[0017] The utility model is further described in combination with the drawings and specific embodiments, so that the technical idea of the utility model claimed is more clearly understood.

[0018] As Figs. 1 to 4 Indicated, a kind of novel air conditioner connecting pipe protection plug, including plug body 1 and pull rod 2, the right side of plug body 1 is uniformly provided with multiple connecting strips 3, the outer side of the end of connecting strip 3 away from plug body 1 is provided with lock hook 4, and the inner side of connecting strip 3 is provided with guide block 5, pull rod 2 is slidably connected with the center of plug body 1, the left end of pull rod 2 is provided with limiting disc 6, and the right end of pull rod 2 is provided with guide disc 7, the side of guide disc 7 opposite to guide block 5 is provided with parallel guide surface 8.

[0019] The working principle of the novel air conditioner connecting pipe protection plug is realized by the cooperation of plug body 1 and pull rod 2, as Figs. 1 to 4As shown, the connecting strip 3 can be made of elastic material such as rubber. When installing the plug body 1, the worker holds the plug body 1 and presses it into the copper nut. The locking hook 4 on the connecting strip 3 abuts against the internal thread of the copper nut and causes the connecting strip 3 to elastically deform inwardly, so that the plug body 1 extends into the copper nut. After the plug body 1 extends into the copper nut, the elastic deformation of the connecting strip 3 recovers and the locking hook 4 is clamped on the internal thread of the copper nut. When disassembling the plug body 1, the worker pulls the limiting disc 6 outwardly. The limiting disc 6 drives the guide disc 7 to move toward the guide block 5 through the pull rod 2. The guide disc 7 abuts against the guide block 5 through the guide surface 8, and the guide disc 7 drives the guide block 5 to move along the central axis of the plug body 1. Then, the guide block 5 drives the connecting strip 3 to elastically deform inwardly, and the locking hook 4 is separated from the internal thread of the copper nut. In this way, the worker can take out the plug body 1 from the copper nut. Compared with the traditional connecting pipe plug, the new air conditioner connecting pipe protection plug does not require the worker to exert a large force to take out the plug body 1 from the copper nut during disassembly. The plug body 1 is easy to disassemble, which can reduce the friction between the locking hook 4 and the internal thread of the copper nut and the corresponding wear.

[0020] Specifically, the locking hook 4 is provided with an inclined guide surface 9 outwardly inclined toward the plug body 1. The guide block 5 is connected to the connecting strip 3 through a connecting rib 10, and the guide block 5 extends toward the central axis of the plug body 1. The inner and outer sides of the part of the connecting strip 3 between the guide block 5 and the plug body 1 are provided with extrusion grooves 11, as shown in the figure. Figs. 1 to 4 As shown, the locking hook 4 abuts against the internal thread of the copper nut through the guide surface 9, which can facilitate the movement of the locking hook 4 along the internal thread of the copper nut, thereby reducing the friction between the locking hook 4 and the internal thread of the copper nut. When installing the plug body 1, the guide disc 7 is separated from the guide block 5, the locking hook 4 abuts against the internal thread of the copper nut, and the connecting strip 3 elastically deforms inwardly. The extrusion grooves 11 can provide space for the elastic deformation of the connecting strip 3.

[0021] Further, the outer side of the plug body 1 is provided with a limiting protrusion 12, and the left side of the plug body 1 is provided with a containing groove 13. Further, the limiting disc 6 is contained in the containing groove 13, and the side of the limiting disc 6 outwardly is provided with a pull handle. The side of the guide disc 7 toward the plug body 1 is provided with a guide groove 14, and the guide surface 8 is arranged on the groove wall around the guide groove 14, as shown in the figure. Figs. 1 to 4 As shown, the limiting protrusion 12 abuts against the copper nut to facilitate positioning of the plug body 1. The containing groove 13 can accommodate the limiting disc 6 and the pull handle, which can reduce the risk of accidental touching of the pull handle and improve the overall aesthetic appearance. The pull handle facilitates the worker to pull the limiting disc 6. The limiting disc 6 can prevent the pull rod 2 from falling off the plug body 1. The guide groove 14 can accommodate the guide block 5 when the guide disc 7 drives the guide block 5 to move.

[0022] The above are only specific embodiments of the present application, and do not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
