Description

Technical Field

[0001] This utility model relates to locks, specifically lock reinforcement structures, traffic locks, and handcuff locks. Background Technology

[0002] Locks generally consist of a lock body and mating parts. Locking is achieved by the mating parts working together with the lock body. In some locks, the lock body is also connected to a chain, such as a handcuff lock. The chain connected to the lock body can rotate relative to it, making it easy to adjust the direction of the lock body. The connection between the lock body and the chain needs to have sufficient thickness because of the need to connect the chain. In order to increase the strength of the chain connection, the diameter of the chain connection is increased, which leads to the need to increase the thickness of the entire lock body, resulting in a significant increase in cost. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a lock reinforcement structure, a traffic lock, and a handcuff lock, which can effectively improve the structural strength of the connection between the lock body and the connecting parts, alleviate the cost increase caused by the need to increase the thickness of the lock body due to the connecting parts, and at the same time prevent the connecting parts from falling out of the lock body, thereby improving the stability of the lock in use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lock reinforcement structure, including a lock body, a connector connected to the lock body, and a reinforcing plate disposed on the side of the lock body, wherein the thickness of the lock body is increased by the reinforcing plate; the side of the connector used to connect to the end of the lock body is provided with a protrusion, the protrusion abutting against the edge of the reinforcing plate to prevent the connector from dislodging from the lock body.

[0021] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0022] Reference Figure 1-5 As shown, a lock reinforcement structure of this embodiment includes a lock body 1, a connector 2 connected to the lock body 1, and a reinforcing plate 3 disposed on the side of the lock body 1. The thickness of the lock body 1 is increased by the reinforcing plate 3. The side of the connector 2 used to connect to the end of the lock body 1 is provided with a protrusion 21. The protrusion 21 abuts against the edge of the reinforcing plate 3 to prevent the connector 2 from falling out of the lock body 1.

[0023] The reinforcing plate 3 is fitted to the side of the lock body 1, strengthening the structural strength of the connection area between the lock body 1 and the connector 2 by locally thickening it. The protrusion 21 at the end of the connector 2 forms a close abutting fit with the edge of the reinforcing plate 3. When the connector 2 is subjected to an outward force that causes it to detach from the lock body 1, the protrusion 21 is blocked and limited by the edge of the reinforcing plate 3, preventing the connector 2 from coming off. At the same time, the reinforcing plate 3 is added only at the connection position, without having to thicken the entire lock body 1, thus alleviating the cost increase caused by the increase in the overall size of the lock body 1. This fit method can meet the requirements of installation space and installation strength at a lower cost while thickening the connector 2.

[0024] In order to facilitate the assembly of the connector 2 and the lock body 1, in one optional scheme, the lock body 1 is provided with an opening 11 at the position corresponding to the connector 2, for the radial part of the connector 2 to enter.

[0025] Since the diameter of connector 2 needs to be increased to increase its strength, the original thickness of the housing does not provide enough installation space. In this solution, the design of opening 11 allows at least a portion of the increased diameter of connector 2 to enter the opening 11, thereby providing sufficient installation space.

[0026] According to those skilled in the art, the following two functions can be achieved by selecting different sizes of the opening 11:

[0027] 1. The size of the opening 11 is adapted to the connector 2, and the connector 2 can be inserted into the target position by entering from the side of the opening 11.

[0028] 2. The size of the opening 11 is smaller than that of the connector 2. When the connector 2 and the lock body 1 are finally installed, the connector 2 can meet the installation space requirements through the smaller opening 11 design. It can also prevent the connector 2 from coming out of the opening 11 laterally, and form a better connection stability in conjunction with the reinforcing plate 3.

[0029] Further optimization can be achieved by selecting the following method: a notch 31 is provided at the position of the reinforcing piece 3 corresponding to the protrusion 21, and the notch 31 is formed by the inward concavity of the edge of the reinforcing piece 3.

[0030] The notch 31 formed by the concave edge of the reinforcing piece 3 matches the protrusion 21 on the connector 2, avoiding assembly interference between the reinforcing piece 3 and the protrusion 21, allowing the reinforcing piece 3 to be more stably fitted to the side of the lock body 1. At the same time, the contact between the protrusion 21 and the edge of the reinforcing piece 3 further improves the anti-dislodgement effect of the connector 2, strengthens the connection function, and ensures the effective performance of the limiting function.

[0031] In some options, a curved transition 22 is provided between the connector 2 and the protrusion 21, and a recess 32 is provided at the position of the notch 31 corresponding to the curved transition 22. The reinforcing piece 3 forms a clearance space for the curved transition 22 through the recess 32.

[0032] The arc transition 22 between the connector 2 and the protrusion 21 can improve the strength between the connector 2 and the protrusion 21. The arc transition 22 can be used as a reinforcement. The recess 32 at the notch 31 provides clearance space for the arc transition 22 structure, preventing the reinforcing plate 3 from being squeezed and collided with the arc transition 22 part of the connector 2, ensuring smooth cooperation between the connector 2 and the reinforcing plate 3, improving the structural stability of the end of the connector 2, and providing better rotational cooperation when the connector 2 needs to be rotated.

[0033] Further optimization can be achieved by selecting the following method: the reinforcing plate 3 has a groove at the position corresponding to the protrusion 21. When the reinforcing plate 3 is installed on the lock body 1, the protrusion 21 is located in the groove.

[0034] The groove on the reinforcing plate 3 provides a dedicated space for the protrusion 21. After the protrusion 21 is embedded in the groove, it can be further limited, reducing the radial and axial movement of the protrusion 21, improving the tightness of the fit between the protrusion 21 and the reinforcing plate 3, and more effectively preventing the connector 2 from coming out. At the same time, it makes the overall structure of the lock body 1, the reinforcing plate 3 and the connector 2 more compact.

[0035] To improve the flexibility of the connection between the connector 2 and the lock body 1, in one optional embodiment, the protrusion 21 is an annular protrusion 21 that extends circumferentially along the end of the connector 2 and connects end to end. The protrusion 21 rotates and engages with the lock body 1.

[0036] The annular protrusion 21 is continuously arranged around the end of the connector 2, so that the protrusion 21 and the lock body 1 form a circumferential rotational fit, allowing the connector 2 to rotate freely relative to the lock body 1, adapting to the angle adjustment needs of different use scenarios of the lock. The contact area between the annular protrusion 21 and the edge of the reinforcing plate 3 is more uniform, improving the stability of the limiting function.

[0037] In some options, there are two reinforcing plates 3, located on both sides of the lock body 1.

[0038] Two reinforcing plates 3 are symmetrically distributed on the two sides of the lock body 1, which simultaneously increase the thickness of the connection position of the lock body 1 from both sides, further improve the structural strength of the connection part of the lock body 1, make the force on both sides of the lock body 1 more balanced, and improve the overall structural stability of the lock body 1.

[0039] Further optimization can be achieved by means of the following: the two reinforcing plates 3 are fixed to the lock body 1 by riveting or bolting; or both reinforcing plates 3 are fixed to the lock body 1 by welding.

[0040] The two reinforcing plates 3 are connected and fixed to the lock body 1 by riveting. The riveting connection is firm and stable, preventing the reinforcing plates 3 from falling off the lock body 1. At the same time, the riveting process is simple to operate and conducive to mass production and assembly. Similarly, they can also be fixed to the lock body 1 by bolting. If the lock body 1 is made of metal, the reinforcing plates 3 can also be connected by welding.

[0041] This embodiment provides a traffic lock, including any of the lock reinforcement structures described above.

[0042] After integrating the above-mentioned lock reinforcement structure, the traffic lock can improve the structural strength of the connection position between the lock body 1 and the connector 2 with the help of the reinforcing plate 3, which can alleviate the problem of increased cost caused by the overall thickening of the lock body 1. The abutting cooperation between the protrusion 21 and the reinforcing plate 3 can limit the connector 2 from coming out, and improve the stability of the traffic lock during use.

[0043] This embodiment provides a handcuff lock, including any of the lock reinforcement structures described above.

[0044] After applying the above-mentioned lock reinforcement structure, the structural strength of the connection part of the lock body 1 can be improved by the reinforcing plate 3, reducing the cost of the overall thickening of the lock body 1. The cooperation between the protrusion 21 and the reinforcing plate 3 can restrict the connector 2 from coming out of the lock body 1, thus improving the stability of the handcuff lock.

[0045] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
