Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a mechanical anti-theft lock core. Background Art

[0002] Known locks refer to appliances that play a closing role, including locks, keys and their accessories. Although the external shapes of various existing mechanical lock cores vary greatly, the common pin tumbler lock core has a simple structure and a high market share. It mainly consists of components such as a lock housing, a lock core body, and a key, supplemented by pins and pin springs of different lengths, jointly forming the locking and unlocking functions of the lock core. There are lock shell bullet holes on the existing lock core body. For example, a Chinese invention patent with the authorization announcement number CN112854907B discloses a mechanical anti-theft lock core. A T-shaped pin, an upper pin, a spring and a sealing bead are installed in the lock shell bullet hole. The T-shaped pin, the upper pin, the spring and the sealing bead inside the lock shell bullet hole cannot move up and down, which increases the installation difficulty of the T-shaped pin, the upper pin, the spring and the sealing bead. Therefore, it is necessary to improve the existing technology. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a mechanical anti-theft lock core, which designs a hole that can move up and down normally, which is more conducive to the installation of the upper pin, the spring and the sealing bead, and reduces the difficulty of production and manufacturing.

[0005] (2) Technical Solutions to be Adopted

[0006] In order to achieve the above purpose, the technical solutions adopted by the utility model are as follows:

[0007] A mechanical anti-theft lock core includes a lock housing and a rotatable lock core body arranged in the lock housing. An unlocking fork is arranged on the lock housing. A main lock part with a pin structure is arranged on the lock housing. A pin hole is arranged on the main lock part. An installation tube is arranged in the pin hole. A hole is arranged in the installation tube. An internal fitting is installed in the hole.

[0008] Preferably, the internal fitting includes a pin, a spring and a sealing block arranged in the hole. One end of the spring is provided with the pin, and the other end of the spring is provided with the sealing block.

[0009] Preferably, both ends of the lock housing are provided with a groove one and a groove two. A cover plate one is covered at the opening of the groove one, and a cover plate two is covered at the opening of the groove two.

[0010] (3) Technical Effects to be Achieved

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] First, on the main lock part of the present utility model, there are pin holes. An installation pipe is arranged in the pin holes, a duct is arranged in the installation pipe, and an internal fitting is installed in the duct. The designed duct that can move up and down normally is more conducive to the installation of pins, springs, and sealing beads, reducing the difficulty of production and manufacturing.

[0013] Second, at both ends of the lock housing of the present utility model, there are groove one and groove two. A cover plate one is covered at the opening of groove one, and a cover plate two is covered at the opening of groove two. This kind of setting can maintain the integrity of the lock housing while reducing the weight of the lock housing itself. It not only reduces the resources required in production and manufacturing but also helps to reduce the cost input, which is more in line with the production requirements of manufacturing enterprises.

[0022] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0023] Embodiment 1: Refer to Figure 1 、 Figure 2 and Figure 3, A mechanical anti-theft lock core, including a lock housing 1 and a rotatable lock core body 2 disposed within the lock housing 1. An unlocking fork is provided on the lock housing 1, and a main lock portion with a ball structure is provided on the lock housing 1. It is characterized in that: a ball hole 11 is provided on the main lock portion, an installation tube 12 is provided in the ball hole 11, a hole passage 13 is provided in the installation tube 12, and an internal fitting 14 is installed in the hole passage 13. With this setting, the internal fitting 14 can be pre-installed in the hole passage 13 of the installation tube 12, and then the installation tube 12 can be installed into the ball hole 11. In this way, the installation is more relaxed and simple, reducing the installation difficulty and facilitating the reduction of cost investment.

[0024] Embodiment 2: It can be described based on Embodiment 1. For example, Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the internal fitting 14 includes a ball 141, a spring 142 and a sealing block 143 disposed in the hole passage 13. One end of the spring 142 is provided with the ball 141, and the other end of the spring 142 is provided with the sealing block 143. With this setting, it is simple and convenient to install the ball 141, the spring 142 and the sealing block 143 into the hole passage 13 of the installation tube 12.

[0025] Embodiment 3: It can be described based on Embodiment 1 or Embodiment 2. For example, Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the number of the ball holes 11 can be determined according to the length dimension of the lock housing 1, and the number of the ball holes 11 is at least two. Each ball hole 11 is correspondingly installed with the installation tube 12. In this embodiment, fourteen ball holes 11 are adopted, which is more conducive to the installation of the installation tube 12.

[0026] Embodiment 4: It can be described based on Embodiment 1 or Embodiment 2 or Embodiment 3. For example, Figure 1 , Figure 2 and Figure 3 shown, both ends of the lock housing 1 are provided with a groove one 15 and a groove two 16. A cover plate one 17 is covered at the opening of the groove one 15, and a cover plate two 18 is covered at the opening of the groove two 16. With this setting, while maintaining the integrity of the lock housing 1, the weight of the lock housing 1 itself can be reduced. It not only reduces the resources required in production and manufacturing, but also facilitates the reduction of cost investment, and is more in line with the production requirements of production enterprises. Further explanation is that the groove one 15 and the groove two 16 are on the same straight line, and the groove one 15 and the groove two 16 are not connected to each other. With this setting, the integrity of the lock housing 1 will not be damaged.

[0027] The standard parts used in this application document can all be purchased from the market. The specific connection methods of each part all adopt conventional means such as bolts and rivets that are mature in the prior art, and no specific description will be made here.
