Description

Technical Field

[0001] The utility model relates to the technical field of vehicle locking devices, in particular to a manual mechanical vehicle locking mechanism. Background Art

[0002] On existing loading and unloading platforms, after the truck has stopped steadily but before the goods are completely loaded and unloaded, the truck may sometimes receive erroneous information and leave the platform, causing the loaded and unloaded goods to be scattered or to be loaded and unloaded again. Therefore, it is urgent to set a structure for locking the truck in the passage of the loading and unloading platform.

[0003] After searching, it was found that the Chinese utility model patent with authorization publication number CN217925375U discloses a vehicle lock. From its description, it can be seen that it is fixed to the ground or the corresponding wall through a base or a vertical mounting plate. The concave area between the upper end surface of the vertical mounting plate and the upper end surface of the hook is used to lock the truck bumper, so that the truck will not easily detach from the hook during loading and unloading. It is used to lock the rear bumper of the truck, thereby completing the locking of the truck and ensuring the reliable loading and unloading.

[0004] However, the vehicle lock device in the above patent has the following problems: (1) It adopts hydraulic drive, so a hydraulic drive device needs to be set up, which increases the cost of the equipment; (2) The hydraulic cylinder drives the locking hook to rise in the inner cavity, but when the locking hook reaches the highest point, the locking hook cannot rotate, making it difficult to lock the rear bumper of the truck.

[0009] In the above technical solution, by pressing down the limit rod so that the limit groove leaves the limit gear, the transmission shaft can be rotated to drive the main shaft to rotate. When the locking hook is rotated to the required angle, the limit rod is released, and the limit rod rebounds under the action of the torsion spring and is stuck on the limit gear, thereby limiting the main shaft and preventing the locking hook from reversing.

[0010] Preferably, one end of the transmission shaft away from the main shaft is connected with a handle.

[0011] The above technical solution facilitates the rotation of the transmission shaft and the main shaft through the handle.

[0012] Preferably, the two sides of the housing are connected with relatively extending mounting ears, and are connected with a cover plate through the cooperation of the mounting ears and screws, and the cover plate is provided with an opening to accommodate the rotation of the lock hook.

[0013] In the above technical solution, when the locking hook is not in use, the locking hook is hidden in the housing and will not hinder the reversing of the truck. When the truck is reversed to a suitable position, the locking hook can be turned out from the opening.

[0014] Preferably, a booster spring is sleeved on the first rotating shaft, one end of the booster spring abuts against the locking hook, and the other end abuts against the cover plate.

[0015] The above technical solution can improve the smoothness of the first rotating shaft through the action of the booster spring.

[0016] Preferably, the vertical mounting plate is provided with a mounting hole, and the fixing plate is provided with a fixing hole.

[0017] According to the above technical solution, the vertical mounting plate can be mounted on the wall through the mounting holes, and the fixing plate can be mounted on the support platform through the fixing holes.

[0018] Preferably, the side of the shell away from the vertical mounting plate is a beveled edge, and the cover plate includes a flat plate and a beveled plate connected to one end of the flat plate, and the beveled plate is buckled on the beveled edge of the shell.

[0019] The above technical solution can reduce the collision with the bottom surface of the rear of the truck by providing an inclined plate.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] (1) The lock hook is rotated by manual mechanical control, eliminating the need for an additional hydraulic drive system, thus reducing costs.

[0022] (2) By rotating the main shaft, the first rotating shaft can be driven to rotate, and the first rotating shaft can drive the locking hook to rotate, so that the locking hook can be stably locked on the bumper of the truck. The position of the main shaft can be limited by the fixer so that the locking hook stays at a suitable angle to adapt to bumpers of different positions or models. BRIEF DESCRIPTION OF THE DRAWINGS
