Description

Technical Field

[0001] This invention relates to the field of lock accessories technology, specifically to a lock cylinder protection structure and a lock cylinder. Background Technology

[0002] A typical lock consists of a lock cylinder, a lock core, and a lock cylinder housing. The principle is that when a matching key is inserted into the lock cylinder, the lock cylinder can rotate inside the lock cylinder housing. The lock cylinder housing is embedded inside the lock core, and the lock cylinder housing and the lock cylinder are locked together by one or more pins to prevent them from falling out.

[0003] The lock cylinder is the core component of a lock. Its principle involves the precise matching of the key with the internal mechanical structure to open and close the lock. The lock cylinder typically contains multiple pins (or tumblers) and a spring assembly. These components are precisely arranged to form the lock's security barrier. When the correct key is inserted into the lock cylinder, the key's teeth align perfectly with the positions of the pins inside, causing them to fall into their corresponding grooves under the spring's force. This allows the lock cylinder to rotate smoothly, which in turn controls the extension and retraction of the bolt (or latch) via a linkage mechanism, completing the opening and closing of the door.

[0004] Chinese Patent Publication No. CN117588110A discloses a lock cylinder, which includes a main body. One end of the main body is provided with a key cylinder, and the other end of the main body is provided with a finger turner. An elongated movable groove is formed on the main body along its length direction. The main body is also provided with a first threaded hole, which communicates with the elongated movable groove and is offset from the midpoint of the length of the elongated movable groove. Linear slide rails are provided on both sides of the elongated movable groove along its length direction. An elongated movable component is movably connected to the elongated movable groove through the linear slide rails. The length of the elongated movable component is less than the length of the elongated movable groove. Springs are provided at both ends of the elongated movable component and between the two sides of the elongated movable groove along its width direction. A second threaded hole is provided on the elongated movable component, which is offset from the first threaded hole when the spring is in its natural state.

[0005] The lock cylinder involved in the above patent still has some obvious shortcomings in actual use. The lock cylinder lacks a structure to protect its surface, which makes it easy to be damaged after being subjected to external impact, affecting the normal use of the lock cylinder. Therefore, we need to propose a lock cylinder protection structure and a lock cylinder. Summary of the Invention

[0006] The purpose of this invention is to provide a lock cylinder protection structure and a lock cylinder, which has the advantage of setting a protective structure on the surface of the lock cylinder to protect the lock cylinder, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a lock cylinder protection structure, comprising a lock cylinder body, wherein protective components for protecting the lock cylinder body are provided at both ends of the lock cylinder body;

[0008] The protective assembly includes a first U-shaped shell and a second U-shaped shell adapted to be disposed on both sides of the lower end of the lock cylinder body. A first arc-shaped shell is fixedly installed on the upper end of the first U-shaped shell. An installation mechanism for installing the first U-shaped shell is provided between one side of the first U-shaped shell and one end of the lock cylinder body. A third U-shaped shell is provided at the corresponding position of one end of the second U-shaped shell. A fixing mechanism for fixing the second U-shaped shell and the third U-shaped shell is provided between one end of the third U-shaped shell and one end of the second U-shaped shell and the lock cylinder body. A first connecting mechanism is provided between the other end of the third U-shaped shell and the other end of the second U-shaped shell. A second arc-shaped shell is fixedly connected to the upper end of both the second U-shaped shell and the upper end of the third U-shaped shell. A second connecting mechanism is provided between one end of the two sets of second arc-shaped shells.

[0009] For example, the installation mechanism includes a mounting plate fixedly installed at one end of the first U-shaped shell and located on one side of the lock cylinder body. A first through hole is opened through one side of the mounting plate, and a mounting rod is adapted to be provided inside the first through hole. The bottom end of the mounting rod is inserted into the inside of the first through hole. A mounting block is fixedly installed on the other side of the mounting plate.

[0010] For example, the mounting mechanism further includes a mounting hole on one side of the lock cylinder body, the interior of the mounting hole being adapted to one end of the mounting rod, and one end of the mounting rod being threadedly connected to the inner cavity of the mounting hole. A mounting groove is provided below the mounting hole and at one end of the lock cylinder body, the mounting groove being correspondingly provided to the mounting block, and the mounting block being connected to the inner cavity of the mounting groove.

[0011] For example, the fixing mechanism includes a fixing plate fixedly installed at one end of the second U-shaped shell and located on one side of the lock cylinder body. A second through hole is provided through one side of the fixing plate. A fixing rod is connected inside the second through hole, and one end of the fixing rod is inserted into the inner cavity of the second through hole.

[0012] For example, the fixing mechanism further includes a fixing hole opened at one end of the lock cylinder body, the interior of the fixing hole being adapted to the surface of one end of the fixing rod, and one end of the fixing rod being threaded to the inner wall of the fixing hole.

[0013] For example, the fixing mechanism further includes two sets of L-shaped limiting plates fixedly installed on both sides of the lock cylinder body and two sets of limiting grooves opened on both sides of one end of the third U-shaped shell. The interior of the limiting groove is adapted to the L-shaped limiting plate, and one end of the L-shaped limiting plate is slidably connected to the inner cavity of the limiting groove.

[0014] For example, the first connecting mechanism includes several sets of connecting rods fixedly installed at one end of the third U-shaped shell and several sets of connecting grooves opened inside the second U-shaped shell. One end of the connecting rod passes through one side of the second U-shaped shell and extends into the interior of the connecting groove, where a baffle is connected. One side of the baffle and inside the connecting groove is connected to a telescopic spring, and one end of the telescopic spring is connected to the inner wall of one end of the connecting groove.

[0015] For example, the second connecting mechanism includes a connecting shell disposed between the two sets of the second arc-shaped shells and a connecting cavity opened inside the two sets of the second arc-shaped shells. An arc-shaped block is adapted to be disposed inside the connecting cavity. The two ends of the connecting shell pass through one side of the two sets of the second arc-shaped shells and extend into the interior of the two sets of connecting cavities to connect with one side of the two sets of arc-shaped blocks.

[0016] For example, the lock cylinder body includes a key lock head, a toggle block, a connecting shaft, and an adjusting lock head. The key lock head is provided in two sets, and the lower ends of one side of the two sets of key lock heads are connected to each other through the connecting shaft. The upper ends of one side of the two sets of key lock heads are connected to both ends of the toggle block. One end of one set of key lock heads is connected to the adjusting lock head.

This solves the problem that the lock cylinder lacks a structure to protect its surface, making it susceptible to damage after being subjected to external impacts. Furthermore, it can further reinforce the lock cylinder body, enabling it to withstand external impacts and preventing it from being easily damaged by criminals. This increases the difficulty of damaging the lock cylinder and improves its anti-theft performance.
