Description

Inner connection adapter sleeve for faucet outlet

technical field

The utility model relates to an adapter sleeve, in particular to an adapter sleeve connected inside a water outlet of a faucet, and belongs to the technical field of F16K in the IPC classification.

Background technique

The inner diameter of the water outlet of the faucet is generally 4 or 6 minutes, but because of the various styles of the faucet, especially some faucets installed in the bathroom (C in Figure 4), the inner diameter of the water outlet of this type of faucet is even as small as 2 or 3 minutes. , These water outlets are equipped with the parts of the water outlet. These faucet outlets will not be equipped with other adapter sleeves, because the bathroom is enough, but in some special cases, it needs to be connected to the faucet, such as an external connection when washing the car. , external connection is required when washing the glass, and external connection is required when flushing 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 tube to cover the external joint. On the other end, the external connection is realized in this way.

Of course, on the transferred products, there are some externally connected adapters that are fastened by tie hoops, and adapters that are fixed by threads (see Figures A and B in Figure 4), but because the parts of the outlet of this type of faucet have short threads , the head of the faucet protrudes, and this type of adapter is not suitable for transferring on these faucets (C in Figure 4).

At present, for this type of faucet, only special internal adapters can be used. One internal adapter corresponds to one specification. In special cases, it needs to be purchased specially, which is very inconvenient and troublesome.

Contents of the invention

The purpose of this utility model is to solve the technical problem that the inner thread of the existing faucet outlet is short, the caliber is different, and one inner connection adapter cannot adapt to the inner diameter of various specifications, and provides a single adapter that can adapt to the inner diameter of various specifications. The faucet outlet is internally connected with an adapter sleeve.

The technical scheme of the problem to be solved by the utility model is as follows:

An adapter sleeve connected inside the water outlet of the faucet, including a sleeve body, is characterized in that: the sleeve body is composed of an upper sleeve and a lower sleeve;

The outer side of the upper port of the upper sleeve is provided with threads, and the port is provided with several gaps, and the port wall on both sides of the gap is provided with film-guiding grooves, and a part of the sealing film sleeve is stuck in the film-guiding groove, and the other part of the sealing film sleeve is fit on the inner wall of the upper sleeve;

The upper port edge of the lower sleeve bears against a compressed elastic ring piece, and the compressed elastic ring piece can be pushed into the inner wall of the upper port port edge of the upper sleeve corresponding to the gap of the upper sleeve when the lower sleeve rotates.

The upper sleeve is screwed to the lower sleeve, and the lower sleeve can be further screwed into the upper sleeve.

The lower sleeve is composed of a lower sleeve body and an extension body forming a step with the lower sleeve body, and the extension body can go deep into the lower end of the upper sleeve body.

The upper cover is made of plastic material.

The beneficial effects of the utility model are as follows:

The utility model compresses the elastic ring piece on the lower sleeve and the upper top to reach the inner wall of the upper sleeve corresponding to the gap set by the upper sleeve, and compresses the elastic ring piece to expand the upper port of the upper sleeve, so that the upper sleeve can be adapted to faucets with inner diameters of various specifications and short threads, and is compatible Strong performance, easy to use, ingenious structure, single production and cost saving.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Figures 1 to 3, the adapter sleeve connected to the faucet outlet includes a sleeve body, and the sleeve body is composed of an upper sleeve 1 and a lower sleeve 2;

The outer side of the upper port 11 of the upper sleeve 1 is provided with a thread 12, and the port 11 is provided with a number of gaps 13, and the port 11 on both sides of the gap 13 has a guide film groove 14 on the wall, and a sealing film sleeve 3 is stuck in the film guide groove 14 One part, the other part of the sealing film cover 3 is set on the inner wall of the upper cover 1;

The upper port 21 mouth edge of the lower sleeve 2 withstands a compressed elastic ring piece 4, and the compressed elastic ring piece 4 can be pushed into the upper sleeve 1 upper port 11 mouth edge inner wall corresponding to the upper sleeve 1 gap 13 when the lower sleeve 2 rotates.

The utility model realizes principle as follows:

When the utility model is implemented, the upper port 11 of the upper cover 1 needs to be less than or equal to the inner diameter of the short-threaded water outlet of the faucet whose head is more protruding as shown in Figure C of Figure 4 on the market.

First move the upper port 11 to the water outlet of the faucet and insert it into the water outlet of the faucet. 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 bears on the compressed spring ring 4 Push into the inner wall of the upper port 11 of the upper sleeve 1 corresponding to the gap 13 of the upper sleeve 11. Because there is a gap 13, the elastic force released when compressing the elastic ring piece 4 is greater than the resistance of the inner wall along the mouth at this time, so that the inner wall at this place The film guide groove 14 is squeezed, and the part of the sealing film cover 3 in the film guide groove 14 is also squeezed to the edge of the outer film guide groove 14 of the upward gap 11, and the outside of the groove edge at this place is provided with threads, so that The entire upper port 11 is expanded and because the elastic force of the compressed elastic ring 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 outlet. At this time, it is only necessary to slightly rotate the upper sleeve 1 on the inner diameter of the faucet outlet. Just tighten it.

In this process, because the elastic ring sheet 4 is compressed to the outermost side of the upper port 11 of the upper sleeve 1 by squeezing the groove wall of the film guide groove 14, the sealing film sleeve 3 located in the film guide groove 14 is well fixed on the upper cover. At the upper port 11 of the sleeve 1, after the upper sleeve body 1 is connected to the water outlet, an ideal sealing effect can be achieved on the periphery of the joint where the upper port of the upper sleeve 1 is connected.

In addition, for the present utility model, since the compressed elastic ring piece 4 cannot be returned to its original position after being ejected, the adapter cannot be reused. connect. Certainly this is not the technical problem that the utility model will solve, should get rid of.

Further, when the utility model is implemented, the upper sleeve 1 and the lower sleeve 2 are screwed together, and the lower sleeve 2 can be further screwed into the upper sleeve 1 . Further rotation is equivalent to a reserved stroke, and this helical stroke is just the same as the height of the compressed elastic ring piece 4. After the lower sleeve 2 is further screwed into the upper sleeve 1, the compressed elastic ring piece 4 just enters the upper port 11 corresponding to the notch 13 within the inner wall.

Further, when the utility model is implemented, the lower cover 2 is composed of a lower cover body 22 and an extension body 23 forming a step with the lower cover body 22 , and the extension body 23 can go deep into the lower end of the upper cover 1 .

Further, when the utility model is implemented, the upper cover 1 is made of plastic material. Compared with metal, the upper cover 1 made of plastic material is easier to expand for the compressed elastic ring piece 4 .
