Description

Technical Field

[0001] The present application relates to the technical field of tiered locks, and in particular to a tiered lock without a lock shell and a pin. Background Art

[0002] The pin lock is a common lock type that uses a series of small spring-loaded pins (pins) to prevent the lock core from rotating. The pin tumbler lock uses a lock body formed by stacking multiple layers of iron cores, such as the Chinese patent publication number: CN209855451U, which is a tumbler lock without a lock core shell.

[0003] At present, in the pin tumbler lock in use, the protective cover is directly installed on the lower end of the tumbler lock. Since the installation structure is relatively simple, it is easy to fall off during use, resulting in a poor waterproof effect. As a result, the lock core will rust after water enters, affecting the normal use of the pin tumbler lock. Therefore, a lock shell-free pin tumbler lock is designed to solve the above-mentioned problems. Utility Model Content

[0004] In order to solve the problem, the present application provides a lock case-free pin tumbler lock.

[0005] The present application provides a lock case-free pin tumbler lock that adopts the following technical solution:

[0007] Preferably, the installation frame is centrally and symmetrically fixedly connected to a No. 1 spring, and the No. 1 spring is fixedly connected to a through slot at a side away from the installation frame.

[0008] Preferably, a fixing groove is provided in the plug block, a gear is rotatably connected in the fixing groove, a threaded rod is fixedly connected to the middle of one side of the gear, the threaded rod is threadedly connected to a top pipe away from the side of the gear, the top pipe is square, and a plug-in frame is clamped on one side of the top pipe.

[0009] Preferably, the rear portion of the gear engages with a gear plate, and the gear plate and the fixing groove are slidably connected.

[0010] Preferably, the lower end of the gear plate is fixedly connected to a pull plate, and the pull plate is located at the bottom of the protection frame.

[0011] Preferably, the upper end of the pull plate is fixedly connected to a tension spring, and the upper end of the tension spring is fixedly connected to an inner wall of the protection frame.

[0012] Preferably, the socket is aligned with the lock body and lock core.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. In the utility model, the plug-in block is used to plug the plug-in frame, so that the protection frame and the lock body can be connected together, which avoids the problem of the protection frame falling off and causing protection failure when the lock cylinder of the lock body is protected by the protection frame.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-5 This application is described in further detail.

[0023] The present application embodiment discloses a lock case-free pin tumbler lock. Figure 1-5A lock case-free pin tumbler lock comprises a lock body 1, wherein both sides of the lower end of the lock body 1 are fixedly connected to an insertion frame 6, a plug-in block 7 is clamped at the lower end of the insertion frame 6, a protection frame 2 is fixedly connected to the lower end of the plug-in block 7, a through groove 21 is provided in the middle of the lower end of the protection frame 2, a mounting frame 3 is slidably connected in the through groove 21, so that the mounting frame 3 can rotate, a socket 32 ​​is provided in the middle of the mounting frame 3, elastic sheets 4 are fixedly connected to both sides of the mounting frame 3, a shielding plate 5 is fixedly connected to the side of the elastic sheet 4 away from the inner wall of the mounting frame 3, the shielding plate 5 shields the socket 32, and the shielding plate 5 shields the socket 32 ​​by driving the shielding plate 5 through the elastic sheet 4 to seal the protection frame 2, thereby preventing the lock core protected in the protection frame 2 from being protected and preventing water from entering the lock core;

[0024] By adopting the above technical solution, the installation frame 3 is centrally and symmetrically fixedly connected to the No. 1 spring 31, and the No. 1 spring 31 is fixedly connected to the through slot 21 at a side away from the installation frame 3. Figure 4 As shown, after the key is inserted into the lock core through the socket 32, it also needs to be able to rotate. The No. 1 spring 31 provided on the mounting frame 3 can drive the mounting frame 3 to recover through the recovery of the No. 1 spring 31 after the key drives the mounting frame 3 to rotate, so that the mounting frame 3 can be used continuously.

[0025] By adopting the above technical solution, a fixing groove is opened in the plug block 7, and a gear 8 is rotatably connected in the fixing groove. A threaded rod 9 is fixedly connected to the middle of one side of the gear 8. The threaded rod 9 is threadedly connected to a jacking pipe 10 on the side away from the gear 8. The jacking pipe 10 is square in shape to prevent the jacking pipe 10 from rotating with the threaded rod 9 when the threaded rod 9 rotates. One side of the jacking pipe 10 is clamped with the plug-in frame 6.

[0026] By adopting the above technical solution, in order to facilitate the rotation of the gear 8, a gear plate 11 is also meshed at the rear of the gear 8, and the gear plate 11 is slidably connected to the fixed groove, which can push the gear plate 11 to move, thereby driving the gear 8 to rotate, so that the gear plate 8 can drive the threaded rod 9 to rotate. Pull the two pull plates 12, so that the two pull plates 12 drive the gear plate 11 to move, and the tension spring 13 is extended, and the gear plate 11 drives the gear 8 to rotate, so that the gear 8 drives the threaded rod 9 to rotate. After the rotation, the tension spring 13 can also be restored, so that the gear plate 11 drives the gear 8 to rotate, and the threaded rod 9 drives the top pipe 10 to restore.

[0027] By adopting the above technical solution, in order to facilitate the rotation of the gear 8, a pull plate 12 is fixedly connected to the lower end of the gear plate 11, the pull plate 12 is located at the bottom of the protective frame 2, and a tension spring 13 is fixedly connected to the upper end of the pull plate 12, and the upper end of the tension spring 13 is fixedly connected to the inner wall of the protective frame 2.

[0028] By adopting the above technical solution, the socket 32 ​​and the lock core of the lock body 1 are aligned. After the key is inserted into the socket 32, it can be directly aligned with the lock core. Therefore, when the lock body 1 is in use, the lock core is limited by the socket 32, and the key only needs to be inserted into the socket 32 ​​to align with the lock core for unlocking operation.

[0029] The implementation principle of a lock shell-free pin Thousand Layer Lock of the embodiment of the present application is as follows: pull the two pull plates 12 so that the two pull plates 12 drive the gear plate 11 to move, and the tension spring 13 extends, the gear plate 11 drives the gear 8 to rotate, so that the gear 8 drives the threaded rod 9 to rotate, and the threaded rod 9 drives the top pipe 10 to move, so that the top pipe 10 enters the fixed groove, and then the lock body 1 is placed in the protection frame 2, so that the plug block 7 is inserted into the plug frame 6, and then release the pull plate 12, so that the tension spring 13 drives the pull plate 12 to recover, and the pull plate 12 drives the gear plate 11 to recover, the gear plate 11 drives the gear 8 to rotate, and the threaded rod 9 drives the top pipe 10 to move, and after being exposed from the fixed groove, it is inserted into the plug frame 6, so that the plug block 7 is clamped with the plug frame 6, so that the protection frame 2 and the lock body 1 are clamped, so that the protection frame 2 can avoid being separated from the lock body 1 during use, so that the protective function of the protection frame 2 is more effective.

[0030] When the lock body 1 needs to be opened, the key is inserted into the socket 32, and the two shielding plates 5 are moved horizontally, so that the shielding plates 5 push the elastic sheet to contract, and the key passes through the socket 32, and then is inserted into the lock core of the lock body 1, and then the key is turned to drive the lock core to rotate. Since the key is in the socket 32, the key will also drive the installation frame 3 to rotate, and the first spring 31 is squeezed, so that the key can rotate normally. When not in use, the elastic sheet 4 pushes the shielding plate 5 to block the socket 32, so that the socket 32 ​​is sealed, thereby ensuring that the protection frame 2 protects the lock core and plays a good waterproof role.
