Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a one-piece bolt lock. Background Art

[0002] There are many types of bicycle locks, but according to the shape of their bolts, they can be divided into crab claw locks and straight bar locks. Crab claw locks are generally installed on the rear frame to lock the rear wheel, while straight bar locks are generally installed on the front leg to lock the front wheel.

[0003] At present, the one-piece bolt locks on the market have the following disadvantages: when the lock is installed on the bicycle rack, it is mostly fixed with bolts. When the bicycle is parked outdoors and locked, the bolts are difficult to protect or hide, and it is easy for the bolts to be turned out manually, causing the lock to be separated from the bicycle, resulting in the risk of bicycle theft;

[0004] For this reason we have designed a one-piece bolt lock. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a one-piece bolt lock which is highly practical, can be operated simply and has a relatively simple structure, thereby solving the problem in the above-mentioned background technology that the bolts are difficult to protect or hide and can be easily turned out manually.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a one-piece bolt lock, including a fixed block, one side of the surface of the fixed block is fixedly connected to a clamping block by bolts, the other side of the surface of the fixed block is slidably connected to a baffle, one end of the baffle is rotatably connected to a guide rod, one end of the guide rod is rotatably connected to a T-block, one side of the T-block is fixedly connected to a pressure plate, one side of the pressure plate is fixedly connected to a spring, a buffer rod is sleeved inside the spring, and one end of the spring is fixedly connected to the internal cavity of the fixed block.

[0007] Optionally, a protective cover is fixedly connected to the surface of the fixed block, and the protective cover can prevent the connection between the baffle plate and the guide rod from being exposed to the outside, and the baffle plate is slidably connected to the surface of the protective cover.

[0008] Optionally, a circular hole is formed on one side of the fixing block, a U-shaped locking rod is inserted into the surface of the circular hole, and a placement hole adapted to the U-shaped locking rod is formed on the other side of the fixing block, and the U-shaped locking rod can be inserted into the placement hole when the vehicle is not locked, thereby facilitating the storage of the U-shaped locking rod.

[0009] Optionally, a lock core is fixedly connected to the top of the fixed block, and a key is inserted into the surface of the lock core, and the key can open the lock core.

[0010] Optionally, a rectangular groove is provided inside the fixing block, and a pressing plate is movably connected to the surface of the rectangular groove, and the pressing plate can move inside the rectangular groove.

[0011] Optionally, a protruding block is provided on the surface of the baffle, and a fixed block is slidably connected to the surface of the protruding block. The protruding block slides on the surface of the fixed block and is difficult to fall off the fixed block.

[0012] The utility model provides a one-piece bolt lock, which has the following beneficial effects:

[0013] The one-piece bolt lock is provided with a fixing block, a bolt, a clamping block, a baffle, a guide rod, a T-block, a pressure plate and a spring. The U-shaped locking rod is inserted into a circular hole on one side of the fixing block so that it abuts against the pressure plate and drives the pressure plate to squeeze the spring, so that the T-block drives one end of the guide rod to move outward, and then the other end of the guide rod rotates at one end of the baffle and pushes the baffle to move toward the bolt, so that the bolt is blocked by the baffle, which plays a role in hiding the bolt, making it difficult for the bolt to be turned out and disassembled when the device is used to lock the bicycle, thereby reducing the risk of bicycle theft.

[0026] In the utility model, the working steps of the device are as follows:

[0027] The first step is to insert the U-shaped locking rod 10 into the circular hole on one side of the fixed block 1, so that it abuts against the pressure plate 7 and drives the pressure plate 7 to squeeze the spring 8, so that the T-block 6 drives one end of the guide rod 5 to move outward, and then the other end of the guide rod 5 rotates at one end of the baffle 4 and pushes the baffle 4 to move toward the bolt 2, so that the bolt 2 is blocked by the baffle 4, which plays a role in hiding the bolt 2, making it difficult for the bolt 2 to be turned out to disassemble the device when the device is locked. When the vehicle is not locked, insert the U-shaped locking rod 10 into the placement hole to facilitate the storage of the U-shaped locking rod 10.
