DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is now described in detail in conjunction with the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the composition related to the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] refer to Figure 1-4 As shown, the utility model provides an anti-disassembly cover for an air-conditioning connecting pipe, comprising a first assembly body 1 and a second assembly body 2, wherein the first assembly body 1 comprises first assembly body side walls 11 on both sides, and the two ends of the first assembly side wall 11 are respectively provided with a first hook portion 12 and a first slot portion 14, the first hook portion 12 comprises a hook arm 121 and a hook 122, the hook arm 121 is arranged at one end of the first assembly body side wall 11, the first slot portion 14 comprises a first slot 141 and a second slot 142 connected to the first slot 141, and the first slot portion 14 is arranged at the other end of the first assembly body side wall 11.

[0022] The second assembly body 2 includes second assembly body side walls 21 on both sides, and the two ends of the second assembly side wall 21 are respectively provided with a second hook portion 22 and a second slot portion 24, the second hook portion 22 includes a second hook arm 221 and a second hook 222, the second hook arm 221 is arranged at one end of the second assembly body side wall 21, the second slot portion 24 includes a third slot 241 and a fourth slot 242, the third slot 241 is arranged at the other end of the second assembly body side wall 21, and the fourth slot 242 is arranged on the second slot 241.

[0023] In some embodiments, the anti-disassembly cover 100 for the air conditioner connecting pipe further includes a first groove 13 disposed between the first hook portions 12 at both ends of the first assembly body 1 and a first boss 15 disposed between the first hook portions 14 .

[0024] In some embodiments, the anti-disassembly cover 100 for the air conditioner connecting pipe further includes a second groove 25 disposed between the second hook portions 24 at both ends of the second assembly body 2 and a second boss 23 disposed between the second slot portions 22 .

[0025] When assembling, the first assembly body 1 and the second assembly body 2 can be conveniently installed by the guiding effect of the first boss 15 and the second groove 25 or the first groove 13 and the second boss 23 .

[0026] The two ends of the first assembly body 1 and the two ends of the second assembly body 2 can be assembled into a whole through the first hook portion 12 and the second slot portion 22, and the first slot portion 14 and the second hook portion 24, respectively.

[0027] In this embodiment, the first hook portion 12 and the second slot portion 22, as well as the second hook portion 24 and the first slot portion 14 adopt anti-disassembly hooks and anti-disassembly slots. The gap between the components after assembly is very small. It is an installable but non-detachable structure and cannot be disassembled after assembly. If forcible disassembly is performed, only the hook or the slot can be destroyed.

[0028] In some embodiments, the first assembly side wall 11 and the second assembly side wall 21 are processed into two semicircular rings of the same shape. In this way, when designing and processing, only one component needs to be prepared, and the embodiment can be completed by swapping the two ends. The first assembly 1 and the second assembly 2 are assembled to form a complete circular ring. This structure is evenly stressed and is not easy to break even if squeezed by external force, and is more solid.

[0029] Optionally, the first assembly body 1 and the second assembly body 2 are injection molded parts, which have low cost, thereby further reducing the cost.

[0030] The utility model also provides an air conditioning connecting pipe structure, including an anti-disassembly cover 100 for the air conditioning connecting pipe and a connecting pipe flexible joint 5, the connecting pipe flexible joint is composed of a connecting pipe 6, a nut 3 and an external thread 7, and the connecting pipe flexible joint 5 is a hollow structure.

[0031] like Figure 5As shown, when in use, the anti-disassembly cover 100 for the air conditioner connecting pipe is assembled at the nut 3 of the connecting pipe flexible joint 5, and the first hook portion 12 of the first assembly body can fall into the second groove portion 22 of the second assembly body by the guiding effect of the first groove 13 and the second boss 23; the second hook portion 24 of the second assembly body can fall into the first groove portion 14 of the first assembly body by the guiding effect of the first boss 15 and the second groove 25. In this way, the anti-disassembly cover 100 for the air conditioner connecting pipe formed by the first assembly body 1 and the second assembly body 2 can be wrapped around the nut 3.

[0032] like Figure 5 As shown, when the anti-disassembly cover 100 for the air conditioner connecting pipe is assembled at the nut 3 of the connecting pipe flexible joint 5, a limiting cavity 4 is formed between the anti-disassembly cover 100 for the air conditioner connecting pipe and the nut 3, and the size of the limiting cavity 4 satisfies the free movement of the anti-disassembly cover 100 for the air conditioner connecting pipe and the nut 3. After the first assembly 1 and the second assembly 2 are assembled, there is a gap in the middle for the connecting pipe 6 to pass through, and the size of the gap ensures that the nut cannot pass through, that is, the nut 3 can freely move up and down and rotate in the anti-disassembly cover 100 for the air conditioner connecting pipe, but cannot fall off.

[0033] By assembling the anti-disassembly cover 100 for the air conditioner connecting pipe at the nut 3 of the connecting pipe flexible joint 5, the hidden danger of refrigerant leakage caused by the accidental disassembly between the pipe joint and the nut can be avoided, which can improve the safety of the air conditioner. In addition, the first assembly body 1 and the second assembly body 2 of the anti-disassembly cover use the same structure, which can be easily processed and can be completely separated into two separate parts, which is convenient to carry. There is no need to deliberately combine them in pairs. They can be installed by simply swapping them during use. When in use, after the pipeline is fixedly connected, it can be connected through the hook part and the groove part set on the side wall of the assembly. The entire anti-disassembly cover is in a circular shape with a smooth outer peripheral surface, which does not affect the normal pipeline connection. After confirming that there is no leakage, protection is performed. The structure is simple and easy to use.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] It should be understood that the terms "length", "width", "up", "down", "front and back", "left and right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
