[0009] A first support is symmetrically arranged in the main body, a pin body is slidingly arranged on the support, the right end of the pin body extends into the separate body, a pin head is vertically arranged on the pin body, a U-shaped locking member is arranged in the separate body, the opening of the locking member is opposite to the main body, and the pin head is engaged with the locking member in the initial state;

[0010] A chuck larger than the diameter of the pin body is arranged on the pin body, and a clamping groove is uniformly arranged on the surface of the chuck;

[0011] A slide rail is arranged in the main body between adjacent supports, a sliding member is arranged on the slide rail, a second support is arranged on the sliding member, a push rod is rotatably arranged on the second support, a push handle is arranged at the end of the push rod, and the push handle is exposed outside the main body; The push rod is provided with an insert matched with the clamping groove.

[0012] Further, a locking disc is fixedly arranged on the pin body between the chuck and the first support close to the direction of the separate body, and a locking spring is arranged between the locking disc and the first support close to the direction of the separate body.

[0013] Through the technical scheme, the locking effect of the pin body is enhanced, the pin head is prevented from being separated from the locking piece under the action of external force, and the locking spring can provide a reverse force to push the push rod back through the chuck when the pin head is released.

[0014] Further, the second support and the push rod are concentric circular structures with the pin body and have an inner diameter greater than the diameter of the pin body.

[0015] Through the technical scheme, the overall structure is more compact, the space occupation is reduced, and the design of the inner diameter being greater than the diameter of the pin body can also avoid the collision of the push rod with the pin body when the push rod is moved by the sliding member.

[0016] Further, the number of the chucks is greater than the number of the inserts.

[0017] Through the technical scheme, the operation flexibility of the latch is increased, the rotation of the push rod can have more clamping positions, and the clamping can be achieved faster, and the adaptability and reliability of the latch are improved.

[0018] Further, the latch box comprises a back plate, a panel is detachably arranged on the back plate, and at least two fixing holes are arranged on the back plate.

[0019] Through the technical scheme, the installation and disassembly of the latch box are more convenient, and the latch box is convenient to maintain and replace; meanwhile, the fixing points cannot be seen at the first time from the visual angle, and the overall aesthetic degree is improved.

[0020] In summary, the present application has at least one beneficial technical effect:

[0021] (1) Through the design of the locking disc and the locking spring, the spring latch can more effectively maintain the clamping state of the pin head and the locking piece when subjected to external force, and prevent accidental separation;

[0022] (2) Meanwhile, the design that the number of chucks is greater than the number of inserts provides more clamping positions for the rotation of the push rod, and improves the operation flexibility and adaptability of the latch. DETAILED DESCRIPTION
