Description

Vacuum cleaner hose connector with new sealing structure

technical field

The utility model relates to a vacuum cleaner hose joint with a novel sealing structure. the

Background technique

Existing vacuum cleaner hoses and joints are connected by threads and glue is added. When this connection method is mass-produced, the reliability of the glue seal is often not guaranteed, and there will be air leakage. the

Contents of the invention

The purpose of the utility model is to provide a vacuum cleaner hose joint which prevents air leakage and has a novel sealing structure. the

The technical scheme of the utility model is: a vacuum cleaner hose joint with a new type of sealing structure, which includes a vacuum cleaner hose, a joint part sleeved on the vacuum cleaner hose, and A gasket for sealing between the joint and the joint. the

On the basis of the above technical solutions, the following subsidiary technical solutions are further included:

The joint portion has an internal thread that is sealingly engaged with the sealing sheet. the

The sealing sheet is ethylene-vinyl acetate copolymer. the

The utility model advantage is:

In the utility model, a sealing sheet is added in the threaded groove of the hose, and at the same time, glue is applied and screwed into the hose joint, so as to play a reliable role in sealing and prevent air leakage. the

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the partially enlarged cross-sectional schematic diagram of A place of Fig. 1;

Among them: 1. Joint part; 10. Internal thread; 2. Vacuum cleaner hose; 3. Sealing sheet. the

Detailed ways

Embodiment: As shown in Figure 1-2, the utility model provides a specific embodiment of a vacuum cleaner hose joint with a new sealing structure, which includes a vacuum cleaner hose 2 with several thread grooves, which is sleeved on a soft vacuum cleaner. The joint part 1 on the pipe 2 and the sealing sheet 3 bonded on the vacuum cleaner hose 2 to seal between the vacuum cleaner hose 2 and the joint part 1 . The connection between the sealing sheet 3 and the joint part 1 is preferably an adhesive connection. the

The joint part 1 has an internal thread 10 sealingly engaged with the sealing sheet 3 . The sealing sheet 3 is an ethylene-vinyl acetate copolymer. the

In the utility model, a sealing sheet is added in the threaded groove of the hose, and at the same time, glue is applied and screwed into the hose joint, so as to play a reliable role in sealing and prevent air leakage. the

Of course, the above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the main technical solutions of the present invention shall fall within the protection scope of the present invention. the

Claims (3)
