detailed description

BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without the creative work are all within the scope of the present invention.

As shown in FIG. 1 to FIG. 3, an embodiment of the present invention provides an airport trolley, including: an armrest 01, a bracket 02, a brake device 03, a front wheel 04, and a rear wheel 05;

The brake device 03 includes a brake line control portion 31, a base 32 connected to the brake line control portion 32, and a brake wire 34 connected to the rear wheel brake pad 33;

The two ends of the brake line control portion 31 are respectively provided with a first rotating shaft 311 and a second rotating shaft 312. The base 32 is provided with a first rotating shaft connecting portion 321 for connecting with the first rotating shaft 311, and a second rotating shaft sliding groove 322 connected to the second rotating shaft 312; a middle portion of the brake wire control portion 31 is provided with a groove for connecting with the brake wire end 35;

The bracket includes a pole 21 and a chassis, and the armrest 01 is fixed to the brake line control unit 31 The base 32 is fixedly connected to the upright 21 .

In the embodiment of the present invention, the control unit brake line control portion 31 of the brake device 03 is disposed between the armrest 01 and the upright 21, specifically, the brake line control portion 31 is fixedly coupled to the armrest 01, and the armrest 01 is controlled. The movement of the brake wire control portion 31 can be controlled, and the brake wire control portion 31 is again coupled to the base 32, and then the base 32 is fixedly coupled to the upright 21 so that the handrail 01 can be pushed to push the entire airport trolley.

The connection between the brake line control unit 31 and the base 32 is specifically provided with a first rotating shaft 311 and a second rotating shaft 312 at two ends of the brake line control unit 31, and a first rotating shaft connecting portion 321 is provided on the base 32. The second rotating shaft sliding slot 321 , the first rotating shaft 311 is pivotally connected to the first rotating shaft connecting portion 321 , that is, the brake line control portion 31 can be rotated by the first rotating shaft connecting portion 321; the second rotating shaft 312 and the second rotating shaft are slid The slot 322 is slidably connected, that is, the second rotating shaft 312 can be slid in the second rotating shaft sliding slot 322, and the upper and lower slots of the second rotating shaft sliding slot 322 serve as a limiting function for sliding the second rotating shaft 312.

After the above-mentioned setting, when the operator presses the armrest 01, the brake line control unit 31 rotates with the first shaft connecting portion 321 as an axis, and lifts up one end of the second shaft 312 of the brake line control portion 31. The groove provided in the middle of the brake line control portion 31 is also lifted upward. Since the end 35 of the brake wire is also disposed in the groove, the brake wire 34 is pulled upward to move the brake pad of the rear wheel 05 of the airport trolley. 33 is lifted up, so that the rear wheel 05 loses the lock of the brake pad 33, so that the airport trolley can be flexibly moved by the operator.

After the above settings, the effect achieved in practical applications is that the operator's rear wheel of the airport trolley is locked before the operator operates the airport trolley, and the airport trolley cannot move; thereby preventing the airport trolley from slipping out of control, avoiding uncontrolled slipping and colliding after others The resulting injury or loss of property. When an airport trolley is required, the operator can press the handrail to make the rear wheel free, so that the airport trolley can be easily moved under the driving force of the operator. As shown in FIG. 4, in the embodiment of the present invention, the first rotating shaft connecting portion of the base may specifically be a first rotating shaft sliding groove. Specifically, in this embodiment, the first connecting portion connecting the brake line control portion and the base may also be arranged as a sliding slot like the second rotating shaft sliding slot, so that after the brake line control portion is connected with the base, the brake line is The first rotating shaft of the control portion can slide in the sliding groove of the first rotating shaft. After the connecting, the first rotating shaft can slide in the sliding groove of the first rotating shaft, and the upper and lower slots of the sliding groove of the first rotating shaft serve to limit the first rotating shaft. .

In the embodiment of the present invention, when the operator presses the armrest, the first rotating shaft of the brake line control portion drives the lower edge of the sliding groove of the first rotating shaft, and then the brake line control portion takes the first rotating shaft as the axis. The heart rotates, so that the groove of the middle portion of the brake line control portion is also lifted upward to release the brake pads of the rear wheel, so that the airport trolley can be moved.

In addition, the operator can also raise the handrail above, which will drive the second rotating shaft of the brake line control portion against the lower edge of the sliding groove of the second rotating shaft, and then the brake line control portion rotates with the second rotating shaft as the axis, so that The groove that drives the middle section of the brake line control section is also lifted up to release the brake pads of the rear wheel, so that the airport trolley can be moved.

Through the above settings, the operator can control the brake pads of the rear wheel of the airport trolley by lifting or lowering the handrail, thereby effectively improving the handling flexibility of the airport trolley.

In order to improve the safety of the airport trolley and avoid the danger of the brake line being exposed, and also to make the appearance of the airport trolley more tidy and beautiful, in the embodiment of the present invention, the brake wire may be disposed through the hollow cavity of the pole and the Rear brake pads are connected.

Further, in order to improve the service life of the brake device and reduce the maintenance cost, in the embodiment of the present invention, a brake wire lead sleeve may be further disposed at a joint where the base and the pole are fixedly connected. Brake sleeve It is installed in the brake wire bushing to reduce the friction between the brake wire and the joint, thus reducing the wear of the brake wire and improving the service life of the entire brake device.

In addition, in the embodiment of the present invention, a base cover is further disposed, and the base cover is fastened to the outside of the brake line control portion after being fastened to the base. Therefore, the brake device is completely packaged in the base cover and the base, thereby avoiding the exposure of the mechanical components of the brake device, thereby making the appearance of the airport trolley more neat and beautiful.

In summary, in the embodiment of the present invention, a brake line control portion of the brake device is provided, and an armrest is provided at one end of the brake line control portion, thereby driving the operator to press down or lift the armrest. The slot for connecting the end of the brake line in the middle of the brake line control section moves upward, and finally lifts the brake line, releasing the brake pad that locks the rear wheel, thereby facilitating the manipulation of the airport trolley.

In the embodiment of the present invention, the brake pad always locks the rear wheel in an unmanned state, so that once the operator leaves the handrail of the airport trolley, the airport trolley automatically stops and stops. When the controller presses down or lifts the armrest, the brake pads are released, so that the airport trolley is in a controlled state, and it is convenient to travel and turn.

The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments are obvious to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded to the broadest scope of the principles and novel features disclosed herein.
