In addition, "first", "second", "third", "fourth" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0043] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0044] Please refer to Figure 3In the embodiment, a lock is provided, which comprises a first lock body 1, a second lock body 2 and a transmission mechanism 3. The transmission mechanism 3 is arranged in a mounting cavity 16 of the first lock body 1. The second lock body 2 comprises a lock tongue 23, which can extend into the mounting cavity 16 and cooperate with a hook 322 in the transmission mechanism 3, so as to realize the opening and closing of the locking structure of the first lock body 1 and the second lock body 2.

[0045] Specifically, the transmission mechanism 3 comprises a first transmission member 31 and a second transmission member 32. Please refer to Figure 8 The second transmission member 32 comprises a rotating part 321, a second connecting end 323 and the hook 322. The second transmission member 32 is arranged in the mounting cavity 16 by the rotating part 321, and the hook 322 and the second connecting end 323 are arranged on the circumferential side of the rotating part 321. When the second transmission member 32 rotates, the hook 322 and the second connecting end 323 will naturally rotate around the rotating part 321. The hook 322 can cooperate with the lock tongue 23. When the lock tongue 23 extends into the mounting cavity 16, the hook 322 and the lock tongue 23 can be locked or opened according to the rotation of the rotating part 321.

[0046] The first transmission member 31 is arranged on the circumferential side of the second transmission member 32, which can avoid the internal components of the transmission mechanism 3 being too dispersed, and improve the concentration of the transmission mechanism 3. Please refer to Figure 9 The first transmission member 31 comprises a first transmission end 312 which is movably connected with the second connecting end 323, and a first connecting end 311 which is connected with a force applying member 12. The force applying member 12 can drive the first connecting end 311 to move. The first connecting end 311 and the first transmission end 312 are both arranged on the first transmission member 31, so they will move synchronously, thereby driving the second transmission member 32 to rotate. On this basis, the opening and closing of the lock tongue 23 and the hook 322 can be realized by the force applying member 12.

[0047] It should be noted that the first lock body 1 and the second lock body 2 are arranged on the circumferential side of the rotating part 321 and integrated in a distribution circle with the rotating center of the rotating part 321 as the center, so that the overall structure of the lock is more concentrated on the circumferential side of the second transmission member 32, the overall structure is more compact, and the overall volume of the lock is smaller.

[0048] In combination with the above embodiments, the first transmission member 31 can drive the second transmission member 32 to rotate, so as to realize the opening and closing of the locking structure, and the complexity of the transmission mechanism 3 is reduced. Meanwhile, the first transmission member 31 is arranged on the side of the second transmission member 32, so as to avoid the components in the transmission mechanism 3 being too dispersed, and the concentration of the transmission mechanism 3 is improved. The first lock body 1 and the second lock body 2 are distributed on the side of the transmission part and integrated in a distribution circle with the rotation center of the rotating part 321 as the center, so that the overall structure of the lock piece is in a circular diffusion mode and radiates outward from the rotation center of the rotating part 321, and the overall structure of the lock piece is more compact and smaller in size, and the application range is wider.

[0049] Please refer to Figure 1 , the first lock body 1 comprises a shell 11, and the shell 11 is internally hollow to form a mounting cavity 16. The second lock body 2 comprises a main body 21, and the opposite sides of the shell 11 and the main body 21 are respectively provided with a convex part 13. The convex part 13 is inserted and matched with the concave part 22, and the two are tightly matched to prevent shaking and the like. The lock tongue 23 is arranged on the concave part 22, and the corresponding convex part 13 is provided with a lock hole 111. Please refer to Figure 4 , the lock tongue 23 can be inserted into the mounting cavity 16 through the lock hole 111 and kept in position corresponding to the lock hook 322, so as to realize the buckling and opening of the lock hook 322 and the lock tongue 23 through the rotation of the second transmission member 32.

[0050] Considering that the first lock body 1 and the second lock body 2 need to be integrated in a distribution circle with the rotation center of the rotating part 321 as the center, the outer contour of the first lock body 1 and the second lock body 2 can be arranged in a circular contour, so that when the first lock body 1 and the second lock body 2 are matched, the outer contour of the lock piece structure is circular, and the center of the circle should coincide with or be as close as possible to the rotation center of the rotating part 321, so that the structure of the first lock body 1 and the second lock body 2 is also more concentrated, and the overall compactness of the lock body is improved.

[0051] For the shell 11 provided with the convex part 13, the convex part 13 also has a mounting cavity 16 structure at the corresponding position, and the transmission mechanism 3 can be arranged in the mounting cavity 16 at the corresponding position of the convex part 13, that is, the transmission mechanism 3 is integrated in the range of the convex part 13, so that the overall structure of the transmission mechanism 3 is more compact. The convex part 13 can be arranged in a fan shape, or in a rectangular or other shape, but considering that the rotating part 321 is in a rotating mode to realize the locking with the lock tongue 23, the volume occupied by the convex part 13 is smaller when it is arranged in a fan shape.

[0052] When the convex part 13 is in the shape of a sector, the center of the convex part 13 should be as close as possible to the rotation center of the rotating part 321 or coincide with the rotation center of the rotating part 321, so that the area of the sector of the convex part 13 can be as small as possible under the condition of meeting the space required for the rotation of the rotating part 321, further improving the compactness of the transmission mechanism 3. When the convex part 13 is in other shapes, the center of the convex part 13 should be as close as possible to the rotation center of the rotating part 321 or coincide with the rotation center of the rotating part 321, which can also improve the compactness of the transmission mechanism 3 as much as possible. On the basis of the compact setting of the transmission mechanism 3, the volume of the first lock body 1 and the second lock body 2 around the transmission mechanism 3 can also be as small as possible, further making the lock structure more compact.

[0053] In some embodiments, please refer to Figure 3 To achieve the compactness of the transmission mechanism 3, the first connecting end 311 can be arranged on the lower side of the convex part 13, and the first action end can be extended to the left side of the convex part 13 as an extension part. The second connecting end 323, as an extension part of the second transmission member 32, can be extended to the corresponding position of the first action end, i.e. the left side of the convex part 13, and the lock hook 322 is located on the upper side of the convex part 13. Thus, each part on the first transmission member 31 and the second transmission member 32 can be arranged around the outer periphery of the rotating part 321, improving the structural compactness of the transmission mechanism 3.

[0054] The rotating part 321 and the shell 11 can be connected in a rotating manner by a pin shaft and a pin hole, and the first transmission end 312 and the second connecting end 323 can also be connected in a rotating manner by a pin shaft and a pin hole; that is, the rotating part 321 is a pin hole, and the shell 11 is provided with a pin shaft in the mounting cavity 16, and the pin hole and the pin shaft are in rotating cooperation; similarly, one of the first transmission end 312 and the second connecting end 323 is a pin shaft, and the other is a pin hole, achieving rotating cooperation. The transmission mechanism 3 formed in this way is simpler and has more stable transmission effect.

[0055] The mounting cavity 16 is also provided with an elastic member 15, please refer to Figure 3 The elastic member 15 is located on the right upper side of the convex part 13 and is also arranged along the lateral side of the rotating part 321, one end of the elastic member 15 is connected with the second transmission member 32, and the other end is arranged on the limiting protrusion 14 in the mounting cavity 16, and the elastic member 15 is used to provide the lock hook 322 with a force for facing the lock tongue 23 and being locked with the lock tongue 23. Specifically, when the force applying member 12 pushes the first transmission member 31 to move, the second connecting end 323 connected with the first connecting end 311 will swing, and the second transmission member 32 will rotate around the rotating part 321 as the center to the side, so that the lock tongue 23 is separated from the hook-shaped position of the lock hook 322, and the lock tongue 23 can be separated from the lock hole 111, forming an opening effect, please refer to Figure 4The second transmission member 32 is reset under the elastic force of the elastic member 15, thereby driving the first transmission member 31 to pull the force applying member 12 to reset, please refer to Figure 5 When the second lock body 2 is in position, the lock tongue 23 will be squeezed out of the lock hook 322 through the lock hole 111, and the first transmission member 31 will also be reset by the elastic member 15, so that the lock hook 322 again bites the lock tongue 23 to form the overall closure of the lock, please refer to Figure 3 .

[0056] The elastic member 15 can be a torsion spring, the coil portion of the torsion spring is sleeved on the outer periphery of the pin shaft corresponding to the rotating portion 321, one end of the torsion spring abuts on the second transmission member 32 on the side of the rotating portion 321, and the other end of the torsion spring abuts in the limiting gap 141 between the two limiting blocks 14, please refer to Figure 5 .

[0057] Please refer to Figure 1 and Figure 6 , the force applying member 12 can be a push button arranged on the upper surface of the shell 11, the upper wall of the shell 11 is provided with a limiting groove 112 and a mounting hole 113, and the push button is provided with a limiting portion 121 and a mounting shaft 123 which extend into the limiting groove 112 and the mounting hole 113, please refer to Figure 7 . The mounting shaft 123 is mounted in cooperation with the mounting hole 113 to limit the sliding of the push button on the upper surface of the shell 11; the outer wall of the limiting portion 121 cooperates with the inner wall of the limiting groove 112 to limit the linear movement of the push button along the length direction of the limiting groove 112. The outer wall of the limiting portion 121 can be a polygonal structure, for example, a rectangular structure, and the inner wall of the corresponding limiting groove 112 can cooperate with the polygonal structure, thereby limiting the movement of the push button to ensure that the push button can move linearly along the length direction of the limiting groove 112.

[0058] In addition, the limiting portion 121 is further provided with a connecting shaft 122 which extends into the mounting cavity 16 and cooperates with the first connecting end 311, and the connecting shaft 122 and the first connecting end 311 adopt pin shaft and hole cooperation, that is, the first connecting end 311 is a pin hole structure, and the connecting shaft 122 is inserted into the first connecting end 311, thereby converting the linear movement of the push button into the linear movement of the first connecting end 311, and the two move synchronously.
