Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0041] According to an embodiment of the present invention, a password key 100 is provided, including a body 1, movable teeth 2 and an adjustment component 3. The body 1 has a cavity inside. A plurality of first openings are provided on the side of the body 1 near one end. A plurality of movable teeth 2 are correspondingly and movably installed in the first openings. One end of the movable teeth 2 extends into the body 1 and the other end extends out of the body 1. A second opening is provided on the body 1. The adjustment component 3 is disposed in the second opening. The adjustment component 3 is movably connected to the end of the movable teeth 2 located inside the body 1.

[0042] Specifically, such as Figure 1 and Figure 2As shown, the body 1 is not specifically limited in this embodiment. For example, the body 1 is cylindrical and has a cavity inside. The side of the body 1 near one end is provided with several first openings. A movable tooth 2 is movably disposed in each first opening. The other end of the body 1 is provided with a second opening. The angle between the first opening and the second opening is 90 degrees. The adjustment component 3 is movably installed in the second opening. The adjustment component 3 is movably connected to the movable tooth 2. The movable component is used to drive the movable tooth 2 to be located in different positions in the first opening. The multiple movable teeth 2 located in different positions match the second tumbler 600 in the lock body 200.

[0043] In this embodiment, the number of first openings is not specifically limited. For example, such as Figures 1 to 3 As shown, this embodiment has three first openings, and correspondingly, the number of movable teeth 2 is also three.

[0044] This utility model adjusts the movable teeth 2 in different positions within the first opening of the main body 1 by adjusting the component 3. By adjusting several movable teeth 2 to suitable positions within the first opening, a key suitable for opening different lock bodies 200 can be formed through the combination of several movable teeth 2. During equipment maintenance and inspection in the field, it is not necessary to carry multiple keys; only one password key 100 is needed to open different fence gates. It has the advantages of simple structure, easy portability, and easy operation, ensuring the normal operation of inspection work.

[0045] In one embodiment, such as Figure 1 As shown, the adjustment assembly 3 includes a rotating component 301, a rotating shaft 302, and a gear 303. The number of rotating components 301 matches the number of movable teeth 2. The rotating components 301 are movably installed in the second opening. One end of the rotating shaft 302 is connected to the rotating component 301, and the other end extends into the first opening. The gear 303 is connected to the end of the rotating shaft 302 away from the rotating component 301. The movable teeth 2 are provided with an adjustment component 201, and the gear 303 is movably connected to the adjustment component 201.

[0046] Specifically, in this embodiment, the number of second openings is not specifically limited. For example, in this embodiment, the number of second openings is three, and a rotating component 301 is movably installed in each second opening.

[0047] In this embodiment, the rotating component 301 is not specifically limited. For example, in this embodiment, the rotating component 301 is cylindrical. The circumferential direction of the rotating component 301 is the same as the axial direction of the rotating shaft 302. The rotating shaft 302 is located between the movable tooth 2 and the rotating component 301. One end of the rotating shaft 302 is connected to the rotating component 301, and the other end of the rotating shaft 302 is provided with a gear 303. The gear 303 is movably connected to the adjusting component 201 on the movable tooth 2.

[0048] In this invention, the user operates the rotating component 301 to rotate it to different positions. The rotating component 301 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the gear 303 to rotate, thereby causing the adjusting component 201 and the gear 303 to move relative to each other, so that the movable teeth 2 are located in different positions in the first opening. By rotating multiple rotating components 301 to different positions, various combinations of movable teeth 2 can be achieved, thereby forming the key required to open the corresponding lock body 200 on different fence gates. It has the advantages of simple structure and easy operation.

[0049] In one embodiment, such as Figure 4 As shown, the adjusting member 201 is a rack, the gear 303 is provided with a first tooth, and the rack is provided with a second tooth, and the first tooth and the second tooth mesh with each other.

[0050] Specifically, in this embodiment, the adjusting member 201 is a rack, and the rack is provided with a second tooth that cooperates with the first tooth on the gear 303. The rack is fixed on the side of the movable tooth 2 facing the gear 303, and the first tooth meshes with the second tooth.

[0051] This utility model allows the movable teeth 2 to extend out of the first opening to different positions by meshing the first tooth and the second tooth. Multiple movable teeth 2 can be combined to form the key required to open the corresponding lock body 200 on different fence gates. It has the advantages of simple structure and easy operation.

[0052] In one embodiment, such as Figure 5 As shown, the adjusting member 201 is a sector gear, the gear 303 is provided with a first tooth, the sector gear is provided with a second tooth, and the first tooth and the second tooth mesh with each other.

[0053] Specifically, in this embodiment, the adjusting member 201 is a sector gear with a central angle of less than 180 degrees. The sector gear is provided with a second tooth that engages with the first tooth on the gear 303. The sector gear is fixed on the side of the movable tooth 2 facing the gear 303, and the first tooth meshes with the second tooth.

[0054] In this embodiment, the central angle of the first opening is not less than the central angle of the sector gear.

[0055] This utility model allows the movable teeth 2 to be offset to different positions in the first opening by meshing the first tooth and the second tooth. After multiple movable teeth 2 are combined, they can form the key required to open the corresponding lock body 200 on different fence gates. It has the advantages of simple structure and easy operation.

[0056] In one embodiment, the adjusting member 201 is provided with limiting members at both ends.

[0057] Specifically, in this embodiment, limiting members are provided at both ends of the rack. When the gear 303 moves relative to the rack, the gear 303 can be stopped by abutting against the limiting members.

[0058] In some other embodiments, limiting members are provided at both ends of the second tooth of the sector gear. When the gear 303 moves relative to the sector gear, when the gear 303 abuts against the limiting member, the gear 303 can be stopped.

[0059] This utility model has limiting members at both ends of the adjusting member 201, which can limit the adjusting member 201 and prevent the gear 303 from disengaging from the adjusting member 201.

[0060] In one embodiment, the outer wall of the rotating member 301 is marked circumferentially.

[0061] This utility model has markings on the outer wall of the rotating component 301 to facilitate user operation and adjustment of the rotating component 301 to the desired position.

[0062] In one embodiment, the numbers are 0 to 9.

[0063] Specifically, in this embodiment, the outer wall of the rotating member 301 is provided with number marks from 0 to 9 in sequence. Each number mark corresponds to a different position of the movable tooth 2 in the first opening. By rotating the number marks on the three rotating members 301 to different number combinations, the three movable teeth 2 can be combined into a key that can open different lock bodies 200.

[0064] In one embodiment, the surface of the rotating member 301 is provided with an anti-slip portion.

[0065] Specifically, the anti-slip part is not specifically limited in this embodiment. For example, the anti-slip part can be knurled. Knurling is provided on the outer wall of the rotating part 301. When the user pushes the rotating part 301 with his / her finger, it can provide more friction and prevent the rotating part 301 from slipping on his / her finger.

[0066] This invention provides an anti-slip part on the surface of the rotating part 301, which can increase the friction of the rotating part 301 and facilitate the user's rotation operation.

[0067] In one embodiment, such as Figure 3 As shown, the main body 1 includes a handle portion 101 and a user portion 102. The handle portion 101 has a hollow interior and a second opening is provided on the handle portion 101. The user portion 102 has a hollow interior and a first opening is provided on the user portion 102.

[0068] Specifically, in this embodiment, the handle portion 101 is not specifically limited. For example, in this embodiment, the handle portion 101 is cylindrical, the diameter of the handle portion 101 is larger than the diameter of the use portion 102, and the length of the use portion 102 matches the structure of the lock cylinder 500 in the lock body 200.

[0069] In this embodiment, when the user part 102 is inserted into the lock cylinder 500, the handle part 101 abuts against the lock cylinder 500, which can limit the length of the user part 102 inserted into the lock cylinder 500. At this position, the movable tooth 2 cooperates with the second tumbler 600 inside the lock cylinder 500.

[0070] According to an embodiment of the present invention, on the other hand, as... Figure 6 As shown, a lock body 200 structure is also provided, suitable for the aforementioned combination key 100, including a lock body 200, an elastic element 300, a first pin 400, and a lock cylinder 500. The lock body 200 has a first mounting cavity along a first direction and a plurality of second mounting cavities 210 along a second direction. The second mounting cavities 210 communicate with the first mounting cavities, and the number of second mounting cavities 210 matches the number of movable teeth 2. The elastic element 300 is disposed within the second mounting cavity 210, and the first pin 400 is movable. The lock cylinder 500 is rotatably installed in the first mounting cavity, and the lock cylinder 500 is provided with a third mounting cavity 510 and a fourth mounting cavity 520. The third mounting cavity 510 and the fourth mounting cavity 520 are connected. The third mounting cavity 510 is suitable for the body 1 to be inserted. The fourth mounting cavity 520 matches the second mounting cavity 210. The second pin 600 is movably installed in the fourth mounting cavity 520 and is suitable for abutting against the movable tooth 2.

[0071] Specifically, in this embodiment, the first direction is perpendicular to the second direction. The lock cylinder 500 is rotatably installed in the first mounting cavity. There are three second mounting cavities 210, and each second mounting cavity 210 has an elastic element 300 installed in it. In this embodiment, the elastic element 300 is a spring, and one end of the spring is provided with a first pin 400. The third mounting cavity 510 on the lock cylinder 500 is in the same direction as the second mounting cavity 210, and the fourth mounting cavity 520 is in the same direction as the first mounting cavity. The third mounting cavity 510 is provided with a second pin 600. In this embodiment, the three second pins 600 have different lengths. The length of the movable teeth 2 is matched with the length of the movable teeth 2. When the user rotates the rotating part 301, the length of each movable tooth 2 extending out of the body 1 is matched with the length of the second pin 600. The end of the second pin 600 away from the movable teeth 2 is on the same plane as the top of the third mounting cavity 510. At this time, the user can rotate the combination key 100 to make the lock cylinder 500 rotate, thereby opening the fence door corresponding to the lock body structure. For different lock body structures on different fence doors, the user only needs to carry one combination key 100 and adjust the rotating part 301 to match the movable teeth 2 with the lock cylinder 500 in the corresponding lock body 200 to open the door.
