Description
Technical field
The utility model relates to the run-through channel of the vehicles such as subway, city rail, light rail, is specifically related to a kind of run-through channel end frame locking mechanism.
Background technology
Run-through channel is the important component part of the vehicles such as subway, city rail, light rail.Run-through channel is arranged on two junctions, joint compartment, plays the effect of connection and transition.It is by several run-through channel end frame locking mechanisms, to be connected with car body frame by vestibule diaphragm end frame that the vestibule diaphragm assembly of run-through channel is connected with two ends car body.Traditional car body frame comprises the mount pad being connected with car body frame and the dead bolt being connected with vestibule diaphragm end frame with the locking mechanism of vestibule diaphragm end frame, and the lower end of described dead bolt is positioned at the mounting groove of vestibule diaphragm end frame, and the upper end of described dead bolt is connected through fastener with mount pad.The shortcoming that the run-through channel end frame locking mechanism of prior art exists is: in vehicle operating process, vibrated, dead bolt can occur loosening and skid off in the mounting groove of vestibule diaphragm end frame, can form and unblank to cause vestibule diaphragm to come off from car body when serious, causes safety misadventure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of use more reliable, safer run-through channel end frame locking mechanism.
Technical solution of the present utility model is, a kind of run-through channel end frame locking mechanism with following structure is provided, comprise the mount pad being connected with car body frame and the dead bolt being connected with vestibule diaphragm end frame, described dead bolt is connected through attaching parts with mount pad, and described mount pad is provided with for locking the locking piece of dead bolt.
Compared with prior art, run-through channel end frame locking mechanism of the present utility model has the following advantages.Owing to being provided with in the utility model for locking the locking piece of dead bolt, after being locked, dead bolt can not rotate, also just can not in the mounting groove of vestibule diaphragm end frame, skid off, thereby guaranteed the connection that vestibule diaphragm end frame is connected with car body frame, use run-through channel end frame locking mechanism of the present utility model can make vestibule diaphragm assembly and two ends car body be connected firmly, more reliable in use.Vestibule diaphragm is difficult for coming off from car body, also safer during use.
As a kind of improvement of the present utility model, described locking piece comprises the location ball that at least one plays the role of positioning to dead bolt, and location ball is located in a through hole of mount pad, and on described dead bolt, corresponding described location ball is provided with positioning through hole or positioning groove.Location ball is pushed against on the positioning through hole and positioning groove on dead bolt, and dead bolt is locked, and dead bolt can not be rotated, thereby avoid dead bolt to skid off from the mounting groove of vestibule diaphragm end frame.
As of the present utility model a kind of preferred, be provided with the location ball described in two.Two location balls can play better locking effect to dead bolt, and dead bolt can not be rotated.
Preferred as another kind of the present utility model, described dead bolt is provided with two positioning through hole of corresponding two described location balls, and the diameter of described positioning through hole is less than the diameter of location ball.The diameter of positioning through hole can play position-limiting action to a side of ball than the diameter of location ball is little.Do not need in dead bolt one side, the spacing parts of other increase to be set again, simplified integral structure.
As of the present utility model, also have that a kind of preferably described attaching parts is through the connecting through hole on dead bolt, the center of described two positioning through hole lays respectively on the longitudinal centerline and cross central line of connecting through hole.Convenient processing positioning through hole, can play better locking position-limiting action.
As another kind of improvement of the present utility model, described attaching parts is near one end of mount pad, to be provided with the bolt of fluted nut, is also provided with the elastic component that stops that location ball drops on described bolt, and the slotted nut of described elastic component is pressed on mount pad.The slotted nut of described elastic component is pressed on mount pad and blocks the through hole of locating ball is installed, thereby stops that location ball is given a shock and drops.
