Description

Technical Field

[0001] The utility model relates to a lock. Background Art

[0002] A lock is a device that locks or seals two parts that can be opened relative to each other. A latch is a common lock. It has a lock tongue inside that rotates with the lock cylinder. The rotation of the lock tongue achieves the purpose of hooking and locking. On the doors of some electrical control boxes and safes, multiple locks are usually required. Multiple locks ensure that the box-shaped structure has better protection. When a latch is used, before closing the door, all multiple latches need to be adjusted to the open state. After closing the door, each latch is switched to the closed state in turn. There are inconveniences in the use process. Summary of the invention

[0003] In view of the shortcomings existing in the above problems, the utility model provides a lock.

[0004] To achieve the above-mentioned purpose, the utility model provides a lock, including a main lock body, a lock core, a lock core sleeve, and a lock seat. The lock seat and the main lock body are respectively fixed on two parts that can be opened relatively to each other. The side wall of the lock seat is processed to form a spiral groove, and the upper end of the spiral groove is a card entrance. The lock core can be rotatably arranged inside the main lock body. The lock core is provided with a first pin shaft, and the first pin shaft acts with the track groove formed on the main lock body to limit the rotation angle of the lock core relative to the main lock body. The lock core sleeve is sleeved on the outside of the lock core, and the side wall of the lock core sleeve is formed with a long groove. The two ends of the first pin shaft extend into the long groove, so that the lock core sleeve and the lock core keep rotating synchronously. In addition, a spring is built into the lock core sleeve, so that the lock core sleeve can move axially relative to the lock core. The lower part of the lock core sleeve is provided with a second pin shaft, and the second pin shaft is adapted to the spiral groove.

[0005] Furthermore, a washer and a nut ring are provided on the main lock body, and through the action of the washer and the nut ring, it is convenient to configure the main lock body at the installation hole on the door.

[0006] Furthermore, the upper end of the lock core is a square block, and the lock also has a lock opening that matches the square block.

[0007] Furthermore, a first insertion hole is processed on the lock core, and the first pin shaft is interference-fitted in the first insertion hole.

[0008] Furthermore, a second insertion hole is processed on the lock core sleeve, and the second pin shaft is interference-fitted in the second insertion hole.

[0009] The beneficial effects of the utility model compared with the prior art are as follows: the lock structure is cleverly designed. When a plurality of locks are arranged on a box-shaped structure, when the door is closed, even if the position of the second pin shaft does not correspond to the position of the card entrance, the door can be tightly fitted on the door frame through the contraction of the spring to complete the closed state, and the door panel will not be partially lifted up. In addition, the lock is installed on the outside of the edge of the box body, so that the IP level of the box body is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figures 1 to 4 As shown, a lock of an embodiment of the utility model comprises a main lock body 1, a lock core 2, a lock core sleeve 6, and a lock seat 9. The lock seat 9 and the main lock body 1 are respectively fixed on two parts that can be opened relatively. Generally, the main lock body 1 is fixed on the door, and the lock seat 9 is fixed on the door frame. The side wall of the lock seat 9 is processed to form a spiral groove 91, and the upper end of the spiral groove 91 is a card entrance 92. The lock core 2 can be rotatably arranged inside the main lock body 1. The lock core 2 is provided with a first pin shaft 5. The first pin shaft 5 acts with the track groove 11 formed on the main lock body 1 to limit the rotation angle of the lock core 2 relative to the main lock body 1. At the same time, the first pin shaft 5 limits the axial movement of the lock core 2 relative to the main lock body 1 (see Figure 2), in order to prevent dust and water from entering the lock core 2, the circumference of the lock core 2 can be equipped with a rubber sealing ring as needed; the lock core sleeve 6 is sleeved on the outside of the lock core 2, and the side wall of the lock core sleeve 6 is formed with a long groove 61. The two ends of the first pin shaft 5 extend into the long groove 61, so that the lock core sleeve 6 and the lock core 2 keep synchronous rotation. In addition, the lock core sleeve 6 is built with a spring 7, so that the lock core sleeve 6 can move axially relative to the lock core 2. The lower part of the lock core sleeve 6 is provided with a second pin shaft 8, and the second pin shaft 8 is connected to the lock core 2. The spiral groove 91 forms an adapter; a washer 3 and a nut ring 4 are provided on the main lock body 1, and through the action of the washer 3 and the nut ring 4, it is convenient to configure the main lock body 1 at the mounting hole on the door; the upper end of the lock core 2 is a square block 21, and the lock also has a lock opening matching the square block 21; a first insertion hole is processed on the lock core 2, and the first pin shaft 5 is interference-inserted at the first insertion hole; a second insertion hole is processed on the lock core sleeve 6, and the second pin shaft 8 is interference-inserted at the second insertion hole.

[0017] The lock structure is cleverly designed. When multiple locks are configured on a box-shaped structure, when closing the door, even if the second pin shaft does not correspond to the position of the card entrance, the door can still fit tightly against the door frame through the contraction of the spring to complete the closed state, and the door panel will not be partially lifted up. In addition, the lock is installed on the outside of the edge of the box, which makes the IP rating of the box higher.

[0018] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0019] See also Figure 5 The two sets of locks are arranged on a box-shaped structure. Specifically, the box door is connected to the box body by a hinge, the two main lock bodies 1 are fixed on the door, and the two lock seats 9 are fixed on the door frame. Regardless of whether the second pin shaft 8 is aligned with the card entrance 92, pressing the box door can make the box door close to the box body; when the second pin shaft 8 is not aligned with the card entrance 92, the lock core sleeve 6 will move toward the lock core 2, and the spring 7 will shrink under pressure; thereafter, the lock core 2 is driven to rotate by unlocking the lock, so that the second pin shaft 8 enters from the card entrance 92 and reaches the bottom position along the spiral groove 91, and the locking is completed.

[0020] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
