Description

Tyre lock

The present invention relates to a decomposable tire lock structure that can be used with different through hole positions on different rim frames.

The current tire lock structure used in general vehicles, such as the new type "Tire Lock" patent case No. 469989 announced on December 21, 1990, discloses: a type of tyre lock that can be arbitrarily enlarged and reduced by the distance between two opposed clamping arms Designed and matched with the control of the lock head, it can achieve easy and reliable clamping of the tires, resulting in safety and anti-theft benefits when the vehicle is parked; and the main feature is: the fixed clamping arm of the two pairs of clamping arms is extended with a stop grip , And another movable clamp arm can be assembled on the fixed clamp arm to move to enlarge and reduce the distance between the two clamp arms. A lock head is set between the fixed clamp arm and the movable clamp arm, which can be moved The clamping arm can be displaced or fixed to achieve the anti-theft benefit of operating the clamped tire.

The previous patent application uses a fixed clamp arm and a movable clamp arm to simultaneously clamp the inner and outer sides of the tire to achieve the function of locking and anti-theft. However, because the fixed clamp arm needs to be inserted and locked from the inner side of the tire, the inner side of the tire has a small space that is not easy to operate, and it is inconvenient to disassemble and assemble. In addition, there are two components, a fixed clamping arm and a movable clamping arm, so that the overall lock body is huge, occupies a large space, and is not easy to store and carry.

There is also the new type M355835 "Tire tong lock" patent case announced on May 1, 1998, which discloses: a movable rod is pivotally connected to the caliper body, and a sleeve rod is provided for the movement On the rod, and the lock core seat of the pliers body is equipped with a rotating unit, and the screw part inside the sleeve rod is screwed into There is a screw, mainly because the rotating unit is provided with a rotating rod to be set in the accommodating groove of the screw, and the first latch is fixed outside the accommodating groove of the screw, and the second latch is fixed to the rotating unit On the rotating rod, the second locking block of the second locking seat can be used to engage and drive the first locking block of the first locking seat, so that the sleeve rod can move relative to the screw.

Since there is no shielding device between the clamp body and the outer tube, the previous patent case is easy to be damaged by thieves, and loses the anti-theft function. In addition, the clamp body and the movable rod are connected in a pivotal way, which is also easily damaged. And the moving rod is in an arc-shaped moving track, so its rotation angle is limited, it cannot be opened and closed at an excessively large angle, and cannot be used with the rim frame of a large-size tire, so the anti-theft effect is not ideal.

In addition, there is an invention patent case No. GB2483109 published in the United Kingdom on February 29, 2012. It is attached to the lock with a fixed arm. After the fixed arm passes through the through hole of the rim frame, a lock rod is placed on the wheel. The inner side of the ring frame forms a locked state.
