Description

Technical Field

[0001] The invention relates to an adapter sleeve, in particular to an adapter sleeve connected to a faucet water outlet, and belongs to the technical field of IPC classification No. F16K. Background Art

[0002] The inner diameter of the faucet outlet is generally 4 or 6 points, but because of the variety of faucet styles, especially some faucets installed in the bathroom ( Figure 4 (Figure C in the figure), the inner diameter of the water outlet of this type of faucet is as small as 2 or 3 centimeters. These water outlets are equipped with their own water outlet parts. These faucet outlets will not be equipped with other adapter sleeves, because they are sufficient for use in the bathroom. However, in some special cases, it is necessary to connect to the faucet, such as external connection when washing the car, external connection when washing the glass, and external connection when washing the floor. At this time, it is necessary to unscrew the parts of the water outlet of this type of faucet first, then screw on the matching external joint, and then use a leather hose to cover the other end of the external joint, so that the external connection is achieved.

[0003] Of course, there are some adapters that are externally fastened by ties, and some that are fixed by threads (see Figure 4 However, because the thread of the parts of the faucet outlet is short and the head of the faucet is protruding, this type of adapter is not suitable for these faucets ( Figure 4 Transfer on (C in Figure 1).

[0004] Currently, for this type of faucet, only a dedicated internal adapter can be used. One internal adapter corresponds to one specification. In special circumstances, it is necessary to purchase it specifically, which is very inconvenient and troublesome. Summary of the invention

[0005] The purpose of the present invention is to solve the technical problems that the internal threads of the existing faucet water outlet are short, the diameters are different, and one internal adapter cannot adapt to multiple specifications of inner diameters, and to provide an internal adapter sleeve for the faucet water outlet that can adapt to multiple specifications of inner diameters.

[0006] The technical solution to the problem to be solved by the present invention is as follows:

[0007] The faucet outlet is internally connected to an adapter sleeve, including a sleeve body, characterized in that: the sleeve body is composed of an upper sleeve and a lower sleeve;

[0008] The upper port of the upper sleeve is provided with a thread on the outside, the port is provided with a plurality of notches, and the port wall on both sides of the notches is provided with film guide grooves, a part of the sealing film sleeve is stuck in the film guide groove, and the other part of the sealing film sleeve is sleeved on the inner wall of the upper sleeve;

[0009] The upper port edge of the lower sleeve is supported by a compression elastic ring piece, and when the lower sleeve rotates, the compression elastic ring piece can be pushed into the inner wall of the upper port edge of the upper sleeve corresponding to the notch of the upper sleeve.

[0010] The upper sleeve is threadedly connected with the lower sleeve, and the lower sleeve can be further screwed into the upper sleeve.

[0011] The lower sleeve is composed of a lower sleeve body and an extension body which is stepped with the lower sleeve body, and the extension body can penetrate into the lower end of the upper sleeve.

[0012] The upper sleeve is made of plastic material.

[0013] The beneficial effects of the present invention are as follows:

[0014] The present invention compresses the elastic ring sheet on the upper push of the lower sleeve to the inner wall of the upper sleeve corresponding to the notch of the upper sleeve, and the compressed elastic ring sheet opens the upper port of the upper sleeve, so that the upper sleeve can be adapted to faucets with inner diameters of short threads of various specifications. The present invention has strong compatibility, is easy to use, has a clever structure, can be produced in a single unit, and saves costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] See also Figures 1 to 3 The faucet outlet is internally connected to a transfer sleeve, including a sleeve body, wherein the sleeve body is composed of an upper sleeve 1 and a lower sleeve 2;

[0021] The upper port 11 of the upper sleeve 1 is provided with a thread 12 on the outer side, and the upper port 11 is provided with a plurality of notches 13, and the upper port 11 wall on both sides of the notches 13 is provided with film guide grooves 14, a part of the sealing film sleeve 3 is stuck in the film guide grooves 14, and the other part of the sealing film sleeve 3 is sleeved on the inner wall of the upper sleeve 1;

[0022] The edge of the upper port 21 of the lower sleeve 2 is supported by a compression elastic ring piece 4. When the lower sleeve 2 rotates, the compression elastic ring piece 4 can be pushed into the inner wall of the edge of the upper port 11 of the upper sleeve 1 corresponding to the notch 13 of the upper sleeve 1.

[0023] The implementation principle of the present invention is as follows:

[0024] When the present invention is implemented, the upper end 11 of the upper sleeve 1 needs to be smaller than or equal to the upper end 11 of the upper sleeve 1 currently on the market, and the head is more protruding. Figure 4 The inner diameter of the short threaded water outlet of the faucet in Figure C.

[0025] First, move the upper port 11 to the position of the faucet water outlet and plug it into the inside of the faucet water outlet. At this time, the adapter sleeve cannot completely match the water outlet, and then rotate the lower sleeve 2 so that the lower sleeve 2 pushes the compression elastic ring piece 4 into the inner wall of the mouth edge of the upper port 11 of the upper sleeve 1 corresponding to the notch 13 of the upper sleeve 1. Because of the presence of the notch 13, the elastic force released from the compression elastic ring piece 4 at all times is greater than the resistance of the inner wall of the mouth edge at this time, so that the inner wall there is squeezed toward the film guide groove 14, and part of the sealing film sleeve 3 in the film guide groove 14 is also squeezed toward the groove edge of the film guide groove 14 provided in the upper port 11 (the outer side of the groove edge is provided with threads), causing the entire upper port 11 to expand and because the elastic force of the compression elastic ring piece 4 is released, the external thread of the upper port 11 is pressed to be in close contact with the inner diameter thread of the faucet water outlet. At this time, you only need to slightly rotate the upper sleeve 1 on the inner diameter of the faucet water outlet to tighten it.

[0026] In this process, because the compression elastic ring sheet 4 squeezes the groove wall of the film guide groove 14 to the outermost side of the upper port 11 of the upper sleeve 1, the sealing film sleeve 3 arranged in the film guide groove 14 is well fixed at the upper port 11 of the upper sleeve 1, so that after the upper sleeve 1 is connected to the water outlet, it can have an ideal sealing effect on the periphery of the connection where the upper port of the upper sleeve 1 is connected.

[0027] In addition, for the present invention, since the compressed elastic ring piece 4 cannot be returned to its original position after being ejected, the adapter cannot be reused. Reuse here means removing it from the faucet outlet and then reconnecting it. Of course, this is not the technical problem to be solved by the present invention and should be excluded.

[0028] Furthermore, when the present invention is implemented, the upper sleeve 1 is screwed with the lower sleeve 2, and the lower sleeve 2 can be further screwed into the upper sleeve 1. Further rotation is equivalent to a reserved stroke, and this spiral stroke is exactly the same as the height of the compression elastic ring piece 4. When the lower sleeve 2 is further screwed into the upper sleeve 1, the compression elastic ring piece 4 just enters the inner wall range of the upper port 11 corresponding to the notch 13.

[0029] Furthermore, when the present invention is implemented, the lower sleeve 2 is composed of a lower sleeve body 22 and an extension body 23 which is stepped with the lower sleeve body 22 , and the extension body 23 can penetrate into the lower end of the upper sleeve 1 .

[0030] Furthermore, when the present invention is implemented, the upper sleeve 1 is made of plastic material. Compared with the upper sleeve 1 made of metal, the upper sleeve 1 made of plastic material is easier to expand for compressing the elastic ring sheet 4.
