[Field of Invention]

The present invention relates to a crimp tube adapter detachable structure of a cleaner.

In particular, the present invention relates to a corrugated pipe adapter detachable structure that can be easily separated from the corrugated pipe adapter is connected to the cleaner body.

[Background of invention]

In general, a vacuum cleaner has a dust collecting chamber for storing a dust bag and an electric blowing chamber for storing an electric blower, a suction brush that directly sucks in dust by directly contacting the bottom surface to be cleaned, and makes the suction brush easy to clean by holding. Extension tube with a handle for and can be roughly divided into a corrugated pipe fluidly connecting the body and the suction brush. In particular, the extension tube with the handle is composed of a plurality of pipes and handles that are separated into a suitable length for the convenience of handling in the prefabricated structure, and also the prefabricated structure so that the corrugated pipe and the main body can also be separated and connected. In addition, the corrugated pipe and the main body are formed with a coupler for accommodating the corrugated pipe adapter is coupled to the corrugated pipe at the lower end of the handle formed on the front portion of the main body through which the corrugated pipe is detachably coupled to each other by the corrugated pipe adapter. Conventionally, the crimp tube adapter is simply assembled by inserting the crimp tube adapter, and one side of the corrugator tube adapter or the coupler is usually provided with a release preventing protrusion so that the push button is pressed to detach the crimp tube adapter from the coupler of the main body. Prevents the corrugated tube adapter from being released from the coupler only when the user presses the push button.

However, even in this case, while pressing the push button as described above, it was very inconvenient because the corrugated pipe adapter has to be removed from the coupling hole of the main body.

Accordingly, the present inventors form a circular release preventing projection at a certain portion of the corrugated pipe adapter, and by simply mounting the elastic spring for releasing the corrugated pipe adapter between the release preventing projection and the jaw of the coupling hole of the main body, the corrugated pipe simply presses a push button. To solve the above problems and to complete the present invention by developing a crimp tube adapter detachable structure that can be separated from the adapter of the adapter.

[Purpose of invention]

An object of the present invention is to provide a crimp tube adapter detachable structure of the cleaner.

Another object of the present invention is to provide a corrugated pipe adapter detachable structure that can be easily separated from the corrugated pipe adapter that is connected to the cleaner body.

[Summary of invention]

An object of the present invention is to provide a corrugated pipe adapter detachable structure that can be easily separated from the corrugated pipe adapter that is connected to the cleaner body.

The corrugated pipe adapter detachable structure of the cleaner according to the present invention is a corrugated pipe adapter detachable structure consisting of a corrugated pipe adapter, a corrugated pipe coupled to the corrugated pipe adapter, and a coupler formed in the main body, to form a circular anti-release protrusion at a predetermined portion of the corrugated pipe adapter. And mounting an elastic spring for releasing the corrugated pipe adapter between the release preventing protrusion and the jaw of the coupling hole of the main body, and fixing the elastic push button having the button protrusion partially contacting the release preventing protrusion around the coupling hole. It is characterized by.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[Description of Specific Example of the Invention]

As shown in FIG. 1, the corrugated pipe adapter detachable structure of the cleaner according to the present invention includes a corrugated pipe adapter 1, a corrugated pipe coupled to the corrugated pipe adapter 1, and a coupler 6 formed on the main body 7. In the crimp tube adapter detachable structure, a circular detachment prevention projection (3) is formed at a predetermined portion of the corrugation tube adapter (1), and between the detachment prevention projection (3) and the jaws of the coupling holes (6) of the main body (7). An elastic spring (2) for releasing the corrugated pipe adapter (1) and having a button protrusion (5) partially in contact with the release preventing protrusion (3) around the coupling hole (6) It is characterized by being made by fixing the push button (4).

In the above, the corrugated pipe adapter 1 is the same as or similar to the conventional corrugated pipe adapter 1 except that the anti-separation protrusion 3 is rounded over the entire outer surface thereof.

The release preventing projection 3 is formed roundly over the entire outer surface of the corrugated pipe adapter 1 and partially contacts the button protrusion 5 of the elastic push button 4 described later. In addition, an elastic spring 2 is mounted between the release preventing protrusion 3 and the jaw of the coupling hole 6 of the main body 7 so that the button protrusion 5 of the push button 4 is the release preventing protrusion. When it is spaced apart from the (3) to push out the separation preventing projection (3) by the elasticity of the spring (2) that was compressed.

The elastic spring 2 can be a cylindrical spring 2 which is usually widely used as a mechanical element.

The elastic push button (4) is to move the button portion to the left and right around the fixed part of the push button (4), the elastic push button (4) is a polymer such as plastic commonly used widely It is possible to fabricate, and to those skilled in the art, it is possible to manufacture a push button 4 of a suitable type as shown in Figure 1 using a suitable polymer.

In addition, the push button (4) is characterized in that the button protrusion (5) which is in contact with the detachment prevention projection (3) is formed in part. More preferably, the button protrusion 5 is configured to be inclined at one side thereof so that the crimp tube adapter 1 can be engaged by simply pushing when engaging the corrugated pipe adapter 1 into the coupler 6.

Effects of the configuration and operation of the present invention are as follows.

The crimp tube adapter detachable structure of the cleaner according to the present invention simply presses the push button 4 as described above, so that the button protrusion 5 of the push button 4 is spaced apart from the release preventing protrusion 3. The release preventing protrusion 3 is pushed out by the elasticity of the elastic spring 2 fixed between the release preventing protrusion 3 and the jaw of the coupler 6 of the main body 7. Thus, the entire corrugated pipe adapter 1 is automatically released from the coupler 6.

Although the present invention has been described in detail only with respect to the above-described embodiments, it will be apparent to those skilled in the art that the present invention may be changed or modified within the spirit and scope of the present invention, and such changes or modifications are defined in the appended claims. Should be limited by
