The sleeve according to claim 1, characterized in that it is equipped with sealing couplings located on the housing, which are tapered on both sides of the housing to the end surface. 3.

Description

A utility model is claimed, which is a sleeve designed for connecting tubular products that can be used in household products.

The closest analogues are known from the prior art: RF patents Nos. 62199 (“Sleeve”), 62200 (“Sleeve”), 2560553 (“Conical sleeve”), 2454594 (“Plastic sliding sleeve ...”).

The objective of this utility model is to create a sleeve for connecting tubular products of different diameters, with simplicity of design, reliability in use and adapted for serial production.

The advantages of the claimed sleeve are:

- ease of manufacture,

- reliability in use, which is provided by the material of manufacture of the case, as well as its configuration.

- simplicity of construction and fastening,

- profitability in manufacturing.

The sleeve is manufactured by injection molding and is industrially applicable.

The sleeve consists of a cylindrical body with a through cylindrical hole.

On the outer surface of the cylindrical sleeve body, designed to be placed in the holes of the tubular products, around the circumference on both sides of the body at some distance from the center of the body there are sealing couplings with longitudinal grooves forming longitudinal protrusions, which can reduce the resistance when introducing the sleeve body into the tubular product and to increase friction between the inner wall of the pipe and the sleeve body after placing it in the pipe, which increases the reliability of the connection structure. In this case, each of the couplings, made at a certain distance from the center of the housing, narrows from the end surface side, as a result of which the diameter of the coupling from the end surface side is less than the diameter of the coupling from the housing side.

The end surface of the housing is made in the form of a circle with a through hole.

The sleeve should be dimensioned so that it can be pressed into the hole of the tubular product with slight deformation and thus securely fixed inside the product, which is facilitated by the shape of the sleeve, tapering from the end surface, the presence of longitudinal grooves forming longitudinal protrusions, and a longitudinal through hole.

The sleeve is made of a material with elastic properties, namely rubber or silicone, or soft plastic or other similar materials that do not affect the elastic properties of the sleeve.

The following is an implementation of a utility model with reference to the attached drawings.

In accordance with the description of the claimed utility model is a sleeve consisting of a cylindrical body 1 (Fig. 1, Fig. 2, Fig. 3). At the same time around the circumference on both sides of the housing 1 (Fig. 1, Fig. 2) at some distance from the center of the housing 1 (Fig. 1, Fig. 2) there are sealing couplings with longitudinal grooves forming longitudinal protrusions 2 (Fig. 1, Fig. 2, Fig. 3).

Both couplings are made with a narrowing 3 (Fig. 1, Fig. 2) from the end sides 4 (Fig. 1, Fig. 2) with a through hole 5 (Fig. 1, 3) of the housing 1.

The resulting device with an indentation force on both sides is placed in the holes of the tubular elements, forming a reliable connection.

A utility model is claimed, which is a sleeve designed for connecting tubular products that can be used in household products.

The closest analogues are known from the prior art: RF patents Nos. 62199 (“Sleeve”), 62200 (“Sleeve”), 2560553 (“Conical sleeve”), 2454594 (“Plastic sliding sleeve ...”).

The objective of this utility model is to create a sleeve for connecting tubular products of different diameters, with simplicity of design, reliability in use and adapted for serial production.

The advantages of the claimed sleeve are:

- ease of manufacture,

- reliability in use, which is provided by the material of manufacture of the case, as well as its configuration.

- simplicity of construction and fastening,

- profitability in manufacturing.

The sleeve is manufactured by injection molding and is industrially applicable.

The sleeve consists of a cylindrical body with a through cylindrical hole.

On the outer surface of the cylindrical sleeve body, designed to be placed in the holes of the tubular products, circumferentially on both sides in the form of sealing couplings located at some distance from the center of the body, longitudinally projecting protrusions are made, which allow reducing the resistance when introducing the sleeve body into the tubular product and to increase friction between the inner wall of the pipe and the sleeve body after placing it in the pipe, which increases the reliability of the connection structure. In this case, each of the couplings, made at a certain distance from the center of the housing, narrows from the end surface side, as a result of which the diameter of the coupling from the end surface side is less than the diameter of the coupling from the housing side. The end surface of the housing is made in the form of a circle with a through hole.

As embodiments, the longitudinally located protrusions can be made not only in the form of couplings located at a certain distance from the center of the housing, but also along the entire surface of the cylindrical housing, as well as directly from the end faces of the housing, or at a certain distance from both end faces of the housing.

The sleeve must be dimensioned so that it can be pressed into the hole of the tubular product with slight deformation, and thus securely fix it inside the product, which is facilitated by the shape of the coupling, tapering from the side of the end surface, the presence of longitudinal protrusions and a longitudinal through hole.

The sleeve is made of a material with elastic properties, namely, rubber, silicone, soft plastic and other similar materials that do not affect the elastic properties of the sleeve.
