Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock-related products, specifically a mechanical lock for a motorcycle tail box. Background Technology
[0002] A motorcycle rear cargo box is a storage box installed at the rear of a motorcycle. It is mainly used to store items needed while riding and has waterproof and anti-theft functions. The mechanical lock of a motorcycle rear cargo box is a lock that is opened by inserting a key into the keyhole and rotating it. It belongs to the traditional mechanical lock type.
[0003] However, most existing mechanical locks use a locking hook that directly engages with the stop to lock, resulting in low stability at the engagement point. This poses a risk that the cover may be shaken open while the vehicle is in motion, making it a defective design. Utility Model Content
[0004] The purpose of this invention is to provide a mechanical lock for a motorcycle rear box to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical lock for a motorcycle tail box, comprising a lock body and a latch. A key lock is mounted on the lock body, and a lock cylinder is provided inside the key lock. A swing rod is fixedly connected to both sides of the lock cylinder within the lock body. A stop is rotatably connected to one end of each swing rod. A U-shaped locking element is provided on one side of the stop. The U-shaped locking element includes a latch and a contact element. A concave groove corresponding to the contact element is provided on one side of the stop. A first positioning block is fixedly connected to one end of the U-shaped locking element. A second positioning block is fixedly connected to one side of the lock body located on the U-shaped locking element. A spring connects the first and second positioning blocks. Two symmetrically arranged locking hooks are fixedly connected to one side of the latch.
[0006] In a preferred embodiment of this invention, both ends of the swing rod are rotatably connected to the lock cylinder and the stop via pivot pins.
[0007] As a preferred embodiment of this utility model, both the stop and the U-shaped lock are slidably inserted with rivet posts, and the rivet posts are fixedly connected to the lock body.
[0008] As a preferred embodiment of this utility model, the lock body is provided with a slot corresponding to the position of the U-shaped lock, and the lock hook on the buckle is inserted into the slot.
[0009] As a preferred embodiment of this utility model, the top of the rivet post is provided with a threaded groove, and a limiting screw is threaded into the threaded groove.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] The motorcycle's rear box uses a mechanical lock. When locking, the hook on the latch is inserted into the lock body. The hook presses against the contact of the U-shaped lock, causing the bolt to flip and pass through the hook. The lock cylinder is rotated clockwise. At this time, the lock cylinder drives the swing rod to push the stop, which engages with the contact of the U-shaped lock. The U-shaped lock is then restricted and locked.
[0012] The motorcycle's rear box uses a mechanical lock. To unlock, the lock cylinder is turned counterclockwise, which drives the swing arm to rotate. The swing arm pulls the stop to move to both sides, separating the contact ends of the stop and the U-shaped lock. The U-shaped lock rebounds under the action of the spring, ejecting the U-shaped lock tongue from the lock hook to unlock.
[0013] The motorcycle's rear box uses a mechanical lock, with a thickened U-shaped component inside that engages with a stop to restrict the lock hook. This is unlike traditional rear box lock hooks that directly engage with the stop to lock, which reduces the risk of the lid being shaken open while the vehicle is in motion and improves the anti-theft and shockproof performance.
