Description

Technical Field

[0001] This invention relates to a lock body. Background Technology

[0002] Most existing lock bodies, especially lock shells that are two-part hinges, are made by laser welding or riveting. Laser welding is difficult to process, costly, and has poor strength. Similarly, riveting is also difficult to process, easy to break, and unsightly. Summary of the Invention

[0003] This invention provides a lock body that has the advantages of strong connection, convenient processing, and beautiful surface.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a lock body, including a lock shell and a lock assembly, the lock assembly being installed inside the lock shell, the lock shell including a bottom shell and an upper shell, a snap-fit ​​piece being provided between the bottom shell and the upper shell, the snap-fit ​​piece being "I" shaped, the snap-fit ​​piece including snap-fit ​​connectors at both ends and a connecting part in the middle, a first snap-fit ​​groove being provided on the bottom shell, a second snap-fit ​​groove being provided on the upper shell, a first notch being provided on the first snap-fit ​​groove, a second notch being provided on the second snap-fit ​​groove, the first snap-fit ​​groove and the second snap-fit ​​groove respectively engaging with the snap-fit ​​connectors at both ends of the snap-fit ​​piece, the two ends of the connecting part respectively engaging with the corresponding notches one and two, a guide slope being provided at the front end of the second snap-fit ​​groove, the highest point of the guide slope being higher than the bottom surface of the second snap-fit ​​groove and the second notch, the snap-fit ​​piece having elastic force, the elastic force providing the snap-fit ​​piece to enter the second snap-fit ​​groove along the guide slope and remain within the second snap-fit ​​groove.

[0005] The beneficial effects of this invention are as follows: The entire lock assembly of the lock body is installed on the bottom shell of the lock case. Then, through the "I"-shaped locking piece between the bottom shell and the top shell, the locking head of one end of the locking piece is first inserted into the first slot on the bottom shell, and at the same time, the connecting end of the locking piece is inserted into the first notch. Finally, the top shell is closed on the bottom shell. During this process, the locking head of the other end of the locking piece enters the second slot after passing through the guide slope under the action of elastic force and is held in the second slot. The other end of the connecting part of the locking piece is also inserted into the second notch. Since the highest point of the guide slope is higher than the bottom surface of the second slot and the second notch, the locking head of the locking piece cannot be disengaged from the second slot. Finally, the bottom shell and the top shell of the lock case are firmly connected together by the locking heads at both ends of the "I"-shaped locking piece along the direction of the closing of the bottom shell and the top shell. The locking piece can be made of metal to provide a certain elastic force while also having high strength.

[0006] Furthermore, each of the upper and lower ends of the lock housing is provided with a snap-fit ​​piece and corresponding slot 1, slot 2, notch 1, notch 2 and guide slope. The simultaneous provision of a snap-fit ​​piece at each of the upper and lower ends can further increase the connection fixation while also limiting the opening of the gap caused by the vertical displacement between the bottom and upper shells.

[0007] Further, the elastic member is arranged on the clamping piece, and the elastic member provides elastic force for the clamping piece to enter the second clamping groove and to be kept in the second clamping groove.

[0008] Further, the clamping head of the clamping piece is formed with a slanting fold surface opposite to the connecting part, and the slanting fold surface is consistent with the inclination of the guide slant surface.

[0009] Further, the elastic member comprises a fixed base and an elastic end, the fixed base is arranged on the bottom shell, and the elastic end abuts against the clamping piece and provides elastic force for the clamping piece.

[0010] The application will be further described in detail below in combination with the drawings and embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0020] like Figures 1-9 As shown, the present invention provides a lock body including a lock shell 10 and a lock assembly 20. The lock assembly 20 is installed inside the lock shell 10. The lock shell 10 includes a bottom shell 1 and an upper shell 2. A snap-fit ​​piece 3 is provided between the bottom shell 1 and the upper shell 2. The snap-fit ​​piece 3 is I-shaped and includes snap-fit ​​connectors 31 at both ends and a connecting part 32 in the middle. The bottom shell 1 has a first snap-fit ​​groove 11, and the upper shell 2 has a second snap-fit ​​groove 21. The first snap-fit ​​groove 11 has a first notch 12, and the second snap-fit ​​groove 21 has a second notch 22. The first snap-fit ​​groove 11 and the second snap-fit ​​groove 21 are respectively snapped into the snap-fit ​​connectors 31 at both ends of the snap-fit ​​piece 3. The two ends of the connecting part 32 are respectively snapped into the first notch 12 and the second notch 22. The front end of the second snap-fit ​​groove 21 has a guide slope 23. The highest point of the guide slope 23 is higher than the bottom surface of the second snap-fit ​​groove 21 and the second notch 22. The piece 3 has an elastic force, which provides the snap-fit ​​piece 3 to enter the second slot 21 along the guide slope 23 and remain in the second slot 21. Each of the upper and lower ends of the lock shell 10 is provided with a snap-fit ​​piece 3 and a first slot 11, a second slot 21, a first notch 12, a second notch 22 and a guide slope 23 corresponding to the snap-fit ​​piece 3. The snap-fit ​​piece 3 is also provided with an elastic element 4. The elastic element 4 provides the snap-fit ​​piece 3 with an elastic force to enter the second slot 21 along the guide slope 23 and remain in the second slot 21. The snap-fit ​​joints 31 at both ends of the snap-fit ​​piece 3 form an oblique fold surface with the relative connecting part 32. The oblique fold surface is in the same direction as the guide slope 23. The elastic element 4 includes a fixed base 41 and an elastic end 42. The fixed base 41 is installed on the bottom shell 1. The elastic end 42 abuts against the snap-fit ​​piece 3 and provides the snap-fit ​​piece 3 with an elastic force.
