Description
Technical Field
[0001] This utility model relates to the field of heating equipment assembly technology, specifically to an elastic snap-fit structure and heating equipment. Background Technology
[0002] Traditional heating systems typically consist of a top cover and a main unit. The top cover protects the internal components, and must be removed before maintenance, repair, or replacement. The top cover is usually secured to the main unit with screws. Multiple screws are generally used to fasten the top cover and main unit. To remove the top cover from the main unit, all screws must be removed; similarly, to install the top cover onto the main unit, all screws must be installed and connected before the top cover is securely attached.
[0003] The aforementioned method of connecting the top cover and the body with screws consumes a significant amount of time for disassembling and assembling screws during maintenance, repair, and replacement of internal parts, increasing the labor intensity of operators and severely reducing work efficiency. Utility Model Content

[0005] In a first aspect, this utility model provides an elastic snap-fit structure, comprising: The male buckle has a pair of barbs symmetrically arranged on the two outer sides of the lower part, and a downward protruding end in the middle of the pair of barbs; The casing has an opening at the top; The female buckle body has a pair of elastic tiger mouths symmetrically provided on the two inner sides of the upper part, and the lower part of the pair of tiger mouths is connected by a connecting block; the connecting block is located inside the shell; the pair of tiger mouths expand outwards from the opening; The first elastic element is disposed between the bottom surface of the connecting block and the inner bottom wall of the housing; A connecting rod is located inside the housing, with its upper end rotatably connected to the side wall of the connecting block; a limiting member is provided at the lower end of the connecting rod; the limiting member is positioned facing the inner side wall of the housing. An irregularly shaped stop block is disposed on the inner side wall of the housing; the housing, the female buckle body, the first elastic element, the connecting rod, and the irregularly shaped stop block constitute the female buckle; The elastic buckle structure has the following characteristics: Pressing down on the male buckle causes the end to push downward against the top surface of the connecting block. The limiting member at the lower end of the connecting rod slides along the top surface of the irregularly shaped block to the bottom surface. The connecting block presses down on the first elastic member, and the pair of jaws retract inward while moving downward, resulting in a pair of barbs engaging with the jaws in a locked state. Alternatively, pressing down on the male buckle again causes the end to push downward against the top surface of the connecting block. The limiting member at the lower end of the connecting rod slides along the bottom surface of the irregularly shaped block to the top surface. The first elastic member pushes the connecting block upward, and the pair of jaws expand outward while moving upward, resulting in a pair of barbs disengaging from the jaws in an unlocked state. Beneficial effects: This application adopts the above technical solution. By designing an elastic buckle structure, it conveniently replaces screws for connection, achieving rapid assembly and reliable fixing. Assembly is simple, improving the convenience of maintenance and repair, reducing the labor intensity of operators, and significantly improving work efficiency. Meanwhile, the screwless design of the elastic snap-fit structure of this application reduces the sealing gap that may be generated by traditional screw connections, significantly improving the waterproof, dustproof and leak-proof performance when used in heating equipment. The elastic snap-fit structure of this application has superior sealing performance when making connections, and is especially suitable for heating equipment with high sealing requirements.

Beneficial effects: This application adopts the above technical solution, designing an elastic snap-fit structure to connect the top cover and the body, conveniently replacing screws for connection, achieving rapid assembly and reliable fixing. Assembly is simple, improving the convenience of maintenance and repair, reducing the labor intensity of operators, and significantly improving work efficiency. It has significant innovative value and practical significance for the screwless top cover design of heating equipment. Simultaneously, because the screwless elastic snap-fit structure of this application reduces the sealing gap that may be generated by traditional screw connections, it significantly improves the waterproof, dustproof, and leak-proof performance of the heating equipment.
