[0002] Air conditioning refrigerant pipes refer to the pipes in the air conditioning system that connect the heat exchangers, valves, compressors and other major refrigeration components through which the refrigerant flows, and are usually made of copper pipes.

[0003] At present, the connecting pipes of the indoor and outdoor units of traditional air conditioners are connected by threaded connections to connect the connecting nut and the connecting head. The threaded connection between the connecting nut and the connecting head has the possibility of being disassembled and is easy to be disassembled. Repeated disassembly will cause the connecting nut and the connecting head to loosen, and the loosening of the connecting nut and the connecting head will cause refrigerant leakage.

[0004] Therefore, an air-conditioning connecting pipe protection device is proposed to solve the above-mentioned problems. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Example

[0020] Please refer to Figure 1-5 The utility model provides an air-conditioning connecting pipe protection device, comprising an upper protective shell 1 and a lower protective shell 2. Slots 3 are provided in the middle of both sides of the lower protective shell 2. Insert blocks 4 are fixedly connected to both sides of the bottom of the upper protective shell 1, and each insert block 4 is fixedly connected to the corresponding slot 3. Card slots 5 are provided at the four corners of the lower protective shell 2. Insert plates 6 are fixedly connected to the four corners of the bottom of the upper protective shell 1. A card block 7 is slidably connected to one side of each card plate 6, and each card block 7 is plugged into an opening connected to the corresponding card slot 5.

[0021] Among them, each plug block 4 is slidably connected to a limit block 8 at both ends, each limit block 8 is slidably connected to the limit groove on one side of the corresponding slot 3, each limit block 8 passes through the corresponding plug block 4 and is fixedly connected to a transmission plate 9, each transmission plate 9 is slidably connected to the inner wall of the corresponding plug block 4, and each transmission plate 9 is fixedly connected to a spring 10 on the side away from the corresponding limit block 8, and each end of the spring 10 is fixedly connected to the inner wall of the corresponding plug block 4.

[0022] Among them, there are sockets 11 on both sides of both ends of the lower protective shell 2, and every two corresponding sockets 11 are connected to the side limit grooves of the corresponding slots 3. A locking rod 14 is provided under each socket 11, and each locking rod 14 is rotatably connected to the lower protective shell 2. The end of each locking rod 14 is fixedly connected to a baffle 12, and a through hole 13 is provided at one end of each baffle 12.

[0023] Among them, sealing gaskets 16 are provided at both ends of the placement grooves of the lower protective shell 2 and the upper protective shell 1, each sealing gasket 16 is fixedly connected to the corresponding lower protective shell 2 and the upper protective shell 1, and a sealing plate 15 is provided on the outside of the corresponding lock groove of each locking rod 14, and each sealing plate 15 is plugged into the corresponding lock groove.

[0024] When the lock rod 14 is rotated clockwise, the baffle 12 rotates along with it, so that the through hole 13 rotates to the insertion hole 11. When the lock rod 14 is rotated counterclockwise, the baffle 12 rotates along with it, so that the end of the baffle 12 away from the through hole 13 rotates to the insertion hole 11.

[0025] Specifically, when the present invention is used, the air conditioning connecting pipe is accommodated and covered by the internal space formed after the upper protective shell 1 and the lower protective shell 2 are installed, and the upper protective shell 1 and the lower protective shell 2 are connected and fixed to form an external protective structure for the air conditioning connecting pipe.

[0026] The upper protective shell 1 and the lower protective shell 2 are connected by plugging the plug block 4 into the corresponding slot 3. At the same time, each plug board 6 is inserted into the corresponding card slot 5. After the plug board 6 is fully inserted into the corresponding card slot 5, the card block 7 slides into the corresponding opening, and each spring 10 pushes the corresponding transmission plate 9 to push the corresponding limit block 8 to slide into the corresponding limit slot, thereby realizing the limiting fixation of the corresponding plug block 4 and realizing the connection and fixation of the upper protective shell 1 and the lower protective shell 2.

[0027] When the device needs to be dismantled, the operator needs to use a special key to insert the lock rod 14 into the lock hole and rotate it clockwise to drive the baffle 12 to rotate, rotate one end of the opening 13 of the baffle 12 to the socket 11, and then use a professional tool to insert it into the opening connected to the socket 11 of the lower protective shell 2 and the card slot 5. At the same time, apply pressure to each limit block 8 and the card block 7 to make it slide into the corresponding plug block 4 and plug plate 6, and then pull the upper protective shell 1 upward to dismantle it.

[0028] This product can be disassembled, but first you need to use a special key to rotate the lock rod 14 to drive the baffle 12 to rotate and adjust the position of the through-hole 13, otherwise it will be impossible to push the limit block 8 through the socket 11. Secondly, you need to use a special tool to insert and apply pressure to the eight places of the sockets 11 and through-holes on both sides at the same time, thereby effectively preventing this device from being easily disassembled.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
