[0002] Round steel locks are a type of lock used for security purposes, usually made of metal and with a cylindrical appearance. They are often used to protect items or facilities such as bicycles, motorcycles, door locks, etc. This type of lock has a high degree of security because they are difficult to cut or pry open. Common round steel locks usually have designs that are anti-saw, anti-drill, and anti-pry.

[0003] At present, it is inconvenient to replace the lock core of most round steel locks in use. When the round steel lock is used outdoors, the lock core is often unable to continue to be used due to external factors and the like. The fixed installation method in the relatively simple outdoor environment makes it impossible to quickly replace the lock core, resulting in the round steel lock being unable to continue to be used. Therefore, a round steel lock with a replaceable lock core is designed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a round steel lock with a replaceable lock core. Figure 1-4 A replaceable lock core round steel lock comprises a round steel lock body 1, a lock core 2 is fixedly connected inside the round steel lock body 1, a limit ring 3 is threadedly connected to the round steel lock body 1, and the limit ring 3 is used to limit the assembled round steel lock body 1. The round steel lock body 1 is composed of two mounting blocks, such as Figure 1 As shown;

[0022] By adopting the above technical solution, the rear part of the round steel lock body 1 away from the lock core 2 is fixedly connected to the No. 1 mounting block 4, and the front part of the round steel lock body 1 away from the lock core 2 is fixedly connected to the No. 2 mounting block 5. The No. 1 mounting block 4 and the No. 2 mounting block 5 have the same shape and are symmetrically arranged, and the No. 1 mounting block 4 and the No. 2 mounting block 5 are assembled into a connecting column 6. The No. 1 mounting block 4 and the No. 2 mounting block 5 are both provided with a mounting groove 14 on one side close to each other. The mounting groove 14 of the No. 1 mounting block 4 is slidably connected to the mounting plate 7, and the mounting groove 14 of the No. 2 mounting block 5 is slidably connected to the fixed plate 8. Figure 4 As shown, the fixing plate 8 and the mounting plate 7 are snap-connected.

[0023] By adopting the above technical solution, the fixing plate 8 is fixedly connected to the fixing block 82 on one side close to the mounting plate 7, the fixing block 82 is plugged into the mounting plate 7, a groove is provided at the lower end of the fixing block 82, an elastic sheet 83 is fixedly connected in the groove, the lower end of the elastic sheet 83 is fixedly connected to the clamping block 84, the clamping block 84 clamps the mounting plate 7, the fixing plate 8 drives the fixing block 82 to be inserted into the mounting plate 7, after the insertion, the elastic sheet 83 drives the clamping block 84 to move, so that the clamping block 84 clamps the mounting plate 7, thereby connecting the mounting plate 7 and the fixing plate 8.

[0024] By adopting the above technical scheme, when the fixing plate 8 and the mounting plate 7 are connected and received in the mounting groove 14, in order to keep the fixing plate 8 and the mounting plate 7 always in the mounting groove 14, a No. 1 spring 9 is fixedly connected to the upper end of the mounting plate 7, the upper end of the No. 1 spring 9 is fixedly connected to the inner wall of the mounting groove 14, a No. 2 spring 10 is fixedly connected to one side of the mounting groove 14 of the No. 2 mounting block 5, and a No. 2 spring 10 is fixedly connected to one side of the plug-in block 11. A slot 81 is opened in the middle of the side of the fixing plate 8 away from the mounting plate 7, and the No. 1 spring 10 is used to drive the plug-in block 11 to be plugged into the slot 81, thereby fixing the fixing plate 8.

[0025] By adopting the above technical solution, in order to facilitate the exposure of the fixing plate 8 and the mounting plate 7 from the mounting groove 14 during disassembly, a pull rod 12 is fixedly connected to one side of the plug block 11, and the pull rod 12 is fixedly connected to a pull block 13 away from the side of the plug block 11. The pull block 13 can be pulled to drive the pull rod 12 to move, and the pull rod 12 pulls the plug block 11 to move, so that the plug block 11 is separated from the slot 81 of the fixed plate 8.

[0026] The implementation principle of a replaceable lock cylinder round steel lock of the embodiment of the present application is as follows: rotate the limit ring 3 to separate the limit ring 3 from the round steel column body 1 and the connecting column 6, then pull the pull block 13, so that the pull block 13 drives the pull rod 12 to move, and the pull rod 12 pulls the plug block 11 to move, so that the plug block 11 is separated from the slot 81 of the fixed plate 8. After separation, the No. 1 spring 9 will push the mounting plate 7 to descend, and drive the fixing plate 8 clamped with the mounting plate 7 to descend together, so that the lower ends of the fixing plate 8 and the mounting plate 7 are exposed from the mounting groove 14, as shown in FIG. Figure 2As shown, the card block 84 is then pushed from the bottom to make the card block 84 enter the groove and squeeze the elastic sheet 83 to contract, and then the No. 1 mounting block 4 and the No. 2 mounting block 5 are pulled to separate the No. 1 mounting block 4 and the No. 2 mounting block 5, and the No. 1 mounting block 4 and the No. 2 mounting block 5 respectively drive the mounting blocks of the round steel lock body 1 to separate, and then the lock core 2 is taken out and replaced;

[0027] After replacement, the two mounting blocks can be combined again to form the round steel lock body 1, and the No. 1 mounting block 4 and the No. 2 mounting block 5 can be made to contact each other. At the same time, the fixing plate 8 and the mounting plate 7 can be made to contact each other, and the fixing block 82 can be inserted into the mounting plate 7. After insertion, the elastic sheet 83 drives the card block 84 to extend out from the groove, and the card block 84 is engaged so that the fixing plate 8 and the mounting plate 7 are engaged again. Then, the mounting plates 7 connected together are pushed up, so that the mounting plate 7 and the fixing plate 8 enter the mounting groove 14, and the No. 2 spring 10 pushes the plug block 11 to plug into the slot 81, thereby fixing the mounting plate 7 and the fixing plate 8.
