Description

Technical Field

[0001] The utility model relates to the field of sanitary wares, in particular to a plug installation structure of a water outlet device. Background Art

[0002] The body of the existing water outlet device (such as a shower faucet) is generally formed by injection molding. Since different valves (such as a temperature regulating valve, a water distribution valve, and a flow valve) need to be installed on the body of the water outlet device, the water path of the body of the water outlet device is relatively complex. Therefore, a core pulling hole is provided in the design of the existing body of the water outlet device for core pulling after subsequent injection molding, and the core pulling hole needs to be blocked by a plug. At present, the core pulling hole and the plug are installed by means of a threaded connection. When installing the plug in this way, the plug needs to be rotated many times, and the installation is relatively troublesome.

[0003] In view of the existence of the above problems, it is necessary to study a plug installation structure of a water outlet device, which can facilitate the installation of the plug. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a plug installation structure of a water outlet device, which can facilitate the installation of the plug.

[0005] To achieve the above purpose, the solution of the utility model is:

[0006] A plug installation structure of a water outlet device, which includes a water outlet device body and a plug; the water outlet device body is made of plastic, and the water outlet device body is provided with a core pulling hole that cooperates with the plug. The core pulling hole is provided with at least two installation parts. Each installation part includes an insertion groove located on the inner wall of the core pulling hole and a limiting hole penetrating through the side wall of the core pulling hole. The insertion groove and the limiting hole of the installation part intersect and communicate with each other. The insertion groove axially penetrates through the end of the core pulling hole along the axial direction of the core pulling hole. A limiting rib is convexly provided at a position adjacent to the limiting hole in the insertion groove; the plug is provided with a connection part that cooperates with each installation part of the core pulling hole. The connection part is inserted into the insertion groove of the installation part and then rotated into the limiting hole of the installation part. The connection part is provided with a stop protrusion that is movably stopped and cooperated with the limiting rib; a sealing ring is provided in cooperation with the plug, and the sealing ring is clamped between the plug and the core pulling hole.

[0007] The stop protrusion of the connection part is provided with a stop curved surface.

[0008] The limiting rib is provided with a limiting arc surface.

[0009] The plug is provided with an annular groove for nesting the sealing ring, and both sides of the annular groove are of a reverse arc corner structure.

[0010] The end of the plug is provided with a sunken tool hole.

[0011] The tool hole is in a hexagonal structure.

[0012] A positioning point is provided at the end of the core-pulling hole; and a confirmation point which is movably aligned with the positioning point is provided at the end of the plug.

[0013] The plug is made of plastic.

[0014] After adopting the above scheme, when the plug is installed in the core-pulling hole, the utility model only needs to insert the connection part of the plug into the insertion groove of the corresponding mounting part of the core-pulling hole, and then slightly rotate the plug so that the connection part passes over the limiting rib and rotates into the limiting hole of the mounting part. At this time, the plug is installed in the core-pulling hole; and at this time, the stop protrusion of the connection part cooperates with the stop of the limiting rib to prevent the connection part from retreating to the insertion groove, ensuring that the plug is stably installed in the core-pulling hole, so that the plug will not fall off when it is subjected to the impact force generated by the opening and closing of the water outlet device. As can be seen from the above, when the plug is installed in the core-pulling hole, the utility model is very simple to install, and there is no need to rotate the plug multiple times.

[0025] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0026] like Figures 1 to 6As shown, the utility model discloses a mounting structure of a plug 2 of a water outlet device, which comprises a water outlet device body 1 and a plug 2, and the water outlet device body 1 and the plug 2 can both be made of plastic; wherein, the water outlet device body 1 is provided with a core-pulling hole 11 matched with the plug 2, and the core-pulling hole 11 is provided with at least two mounting parts 111, and the mounting part 111 comprises an insertion groove 1111 located on the inner wall of the core-pulling hole 11 and a limiting hole 1112 penetrating through the side wall of the core-pulling hole 11, and the insertion groove 1111 of the mounting part 111 and the limiting hole 1112 are intersected and connected, and the insertion groove 1111 penetrates the core-pulling hole 11 axially. Through the end of the core-pulling hole 11, an insertion groove 1111 is provided with an inwardly convex limiting rib 1113 near the limiting hole 1112; the plug 2 is provided with a connecting portion 21 that cooperates with each mounting portion 111 of the core-pulling hole 11, the connecting portion 21 is inserted into the insertion groove 1111 of the mounting portion 111 and then rotated into the limiting hole 1112 of the mounting portion 111, the connecting portion 21 is provided with a stop protrusion 211 that cooperates with the limiting rib 1113 as a movable stopper; the plug 2 is matched with a sealing ring 3, the sealing ring 3 is clamped between the plug 2 and the core-pulling hole 11 to ensure the sealing effect of the plug 2 on the core-pulling hole 11.

[0027] When the plug 2 is installed in the core-pulling hole 11, the utility model only needs to insert the connection part 21 of the plug 2 into the insertion groove 1111 of the corresponding mounting part 111 of the core-pulling hole 11, and then slightly rotate the plug 2 so that the connection part 21 passes over the limiting rib 1113 and rotates into the limiting hole 1112 of the mounting part 111. At this time, the plug 2 is installed in the core-pulling hole 11; and at this time, the stop protrusion 211 of the connection part 21 cooperates with the limiting rib 1113 to prevent the connection part 21 from retreating to the insertion groove 1111, ensuring that the plug 2 is stably installed in the core-pulling hole 11, so that the plug 2 will not fall off when subjected to the impact force generated by the opening and closing of the water outlet device.
