Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to a lead-sealed cabinet door lock. Background Art

[0002] Lead-sealed cabinet door locks were originally made of lead, hence the name lead seal. With the development of technology, modern lead seals have been made of more durable and secure materials such as aluminum. This locking device usually has a unique number and is used for one-time use, which means that once locked, any unauthorized opening will be immediately discovered because the lead seal must be broken to open it, and the broken lead seal cannot be used again. In short, the application of lead-sealed cabinet door locks is very extensive.

[0003] However, it still has the following disadvantages in actual use:

[0004] During the production process of existing lead-mounted door locks, molds must be opened and stamped separately. Lead-mounted door locks are not interchangeable with ordinary door locks. If the lead-mounted door locks need to be changed for use later, the lead-mounted door locks can only be discarded due to special needs of the door locks, resulting in a large number of lead-mounted door locks being discarded and unable to be reused. Utility Model Content

[0005] The utility model aims to provide a lead-sealed cabinet door lock to solve the problem raised in the above-mentioned background technology that, during the production process of the existing lead-mounted door locks, molds must be opened and stamped separately, and the lead-mounted door locks are not interchangeable with ordinary door locks. If the lead-mounted door lock needs to be changed for use later, the lead-mounted door lock can only be discarded due to special needs of the door lock, thereby causing a large number of lead-mounted door locks to be discarded and unable to be reused.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a lead-sealed cabinet door lock, comprising:

[0008] A fixing plate, a connecting plate fixed on the outer surface of the bottom end of the fixing plate, a first hole opened in the middle of the connecting plate, a cover plate rotatably connected to the outer surface of the fixing plate and a second hole opened in the middle of the cover plate.

[0009] Furthermore, the diameter of the fixing plate is consistent with the diameter length of the cover plate, and the diameter length of the first hole is consistent with the diameter length of the second hole.

[0010] Furthermore, a connecting shaft is fixed inside one side of the fixing plate, and an outer surface of the connecting shaft is rotatably connected to the cover plate.

[0011] Furthermore, a lock core is fixed in the middle of the fixing plate, and the outer surface of the lock core is in contact with the cover plate.

[0012] Furthermore, one end of the lock core is movably connected to a lock tongue.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] The utility model is used to receive and install the lead sealing wire through the first hole and the second hole. When the cover plate is opened, the lock core installed inside the fixing plate can be exposed, thereby converting the lead-mounted door lock into an ordinary door lock. This solution unifies the door opening with the traditional door lock, enhances the versatility of the door lock, allows the door lock to be reused, and saves resources.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] See also Figure 1-Figure 3 As shown, this embodiment is a lead-sealed cabinet door lock, comprising:

[0026] A fixing plate 1, a connecting plate 4 fixed to the outer surface of the bottom end of the fixing plate 1, a first hole 5 opened in the middle of the connecting plate 4, a cover plate 6 rotatably connected to the outer surface of the fixing plate 1, and a second hole 7 opened in the middle of the cover plate 6;

[0027] The diameter of the fixing plate 1 is consistent with the diameter of the cover plate 6, and the diameter of the first hole 5 is consistent with the diameter of the second hole 7;

[0028] Since the diameters of the fixing plate 1 and the cover plate 6 are consistent, when the cover plate 6 is rotated, the cover plate 6 can completely cover the fixing plate 1, and the first hole 5 and the second hole 7 are provided to receive and install the lead sealing wire;

[0029] A connecting shaft 8 is fixed inside one side of the fixing plate 1, and the outer surface of the connecting shaft 8 is rotatably connected to the cover plate 6;

[0030] The connecting shaft 8 is fixed inside the fixing plate 1. When the cover plate 6 is rotated, the environment in the middle of the fixing plate 1 can be exposed, thereby adjusting the use of the lead-mounted door lock.

[0031] A lock core 2 is fixed in the middle of the fixing plate 1, and the outer surface of the lock core 2 is in contact with the cover plate 6;

[0032] The lock core 2 is the core part of the lead-mounted door lock, which is responsible for controlling the opening and closing of the lead-mounted door lock and can effectively protect the safety of the locked objects;

[0033] One end of the lock core 2 is movably connected with a lock tongue 3;

[0034] The lock tongue 3 is the part that finally performs the locking and unlocking actions in the lead-mounted door lock system. The lock tongue 3 is a key load-bearing component responsible for firmly fixing the door to the door frame, resisting external prying or damage, and ensuring the safety of stored items;

[0035] When installing the lead sealing wire, the cover plate 6 is rotated under the action of the connecting shaft 8. Since the diameters of the cover plate 6 and the fixing plate 1 are consistent, after the cover plate 6 is covered to the surface of the fixing plate 1, the lead sealing wire can be passed through the first hole 5 and the second hole 7.

[0036] When the position of the lead-mounted door lock needs to be changed;

[0037] Since the positions of the door openings are set in a consistent manner, after the lead-mounted door lock is changed to the desired position, the cover plate 6 is rotated under the action of the connecting shaft 8 to expose the lock core 2 in the middle of the fixed plate 1. By inserting the key into the lock core 2, the state of the lock tongue 3 can be changed, thereby completing the opening and closing of the door;

[0038] This step unifies the door opening with the traditional door lock, enhances the versatility of the door lock, makes the door lock reusable, and saves resources.
