Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a telescopic tube structure of a vacuum cleaner. Background Art

[0002] There are many styles of household vacuum cleaners, but the basic structure is the same, which includes a vacuum cleaner, a floor brush, and a vacuum tube connecting the floor brush and the vacuum cleaner body. The vacuum tube is equipped with a conductive component. In order to meet the needs of cleaning, the vacuum tube usually has a telescopic function.

[0003] According to the difference in materials, vacuum cleaner hoses are divided into soft tubes and hard tubes. The reliability of soft tubes is poor, and they are prone to aging and high risk of breakage. In addition, they occupy a large volume and are not beautiful. Hard tubes have good reliability, are more beautiful, and are more popular with consumers. They have broad market prospects. For vacuum cleaner hoses with hard tube structures, how to set a length adjustment scheme that meets the requirements of conductivity reliability and has the convenience of adjustment is a problem of general concern. Higher conductivity reliability can reduce maintenance costs, and the convenience of adjustment can further enhance consumers' user experience.

[0004] After searching, for example, the Chinese utility model patent with the prior art authorization announcement number CN218515675U discloses "a dust suction rod of a handheld vacuum cleaner", including a dust suction rod assembly 1 and a dust suction rod assembly 2, the dust suction rod assembly 2 is plugged into the dust suction rod assembly 1, the dust suction rod assembly 1 is composed of a pipe sleeve and a locking mechanism, the locking mechanism is fixedly installed on one side of the pipe sleeve, and an internal thread is arranged on the end of the pipe sleeve away from the locking mechanism; the dust suction rod assembly 2 is slidably plugged into the interior of the dust suction rod assembly 1, and is fixed by the locking mechanism on the dust suction rod assembly 1, so that the utility model has the function of freely adjusting the telescopic length, the dust suction rod assembly 2 is composed of an inner tube, a connector, a locking sleeve and a hair interception mechanism, the hair interception mechanism is plugged into the interior of the connector, the hair interception mechanism can intercept long objects such as hair, the locking sleeve is slidably sleeved on the outside of the connector, and when the locking sleeve presses the hair interception mechanism, the hair interception mechanism can be fixed;

[0005] However, the applicant found that the conventional vacuum rod adopts a screw, a locking plate and a toothed belt to adjust the length of the vacuum rod. Although it can achieve a certain locking effect, it is not durable enough. Because the vacuum rod is a hollow tube, if the screw is too loose, it will lead to insufficient stability. If it is too tight, it will easily bend and deform the hollow vacuum rod, affecting its use.

[0006] Therefore, in view of the shortcomings of the prior art, it is necessary to design a telescopic tube structure of a vacuum cleaner to solve the above problems. Utility Model Content

[0009] The preferred technical solution is: the inner sleeve is constructed as a cylindrical structure and a buckle is provided on the outside of the plug-in end, and a spring sheet is provided on the inside of the plug-in end of the fixed tube, and the buckle and the spring sheet are arranged in a corresponding matching manner.

[0010] The preferred technical solution is: a guide groove arranged along the axial direction is provided on the outer side of the inner sleeve, and a guide block corresponding to and matching the guide groove is provided on the inner side of the inner sleeve.

[0011] The preferred technical solution is: the elastic member is a spring, the spring is axially arranged between the inner sleeve and the outer sleeve, one end of the spring is fixedly connected to the inner sleeve, and the other end of the spring is fixedly connected to the outer sleeve.

[0012] The preferred technical solution is: a sealing ring is sleeved and fixed on the plug-in end of the movable tube, and the outer diameter of the sealing ring matches the inner diameter of the fixed tube.

[0013] Due to the application of the above technical solution, the utility model has the following beneficial effects:

[0014] The utility model provides a telescopic tube structure of a vacuum cleaner, which realizes the adjustment of the length of the movable tube by axially pulling the outer bushing so that a spring buckle pops out of a buckle groove. After the adjustment is in place, the outer bushing is loosened and automatically resets under the elastic action of the elastic member so that the spring buckle is set in the buckle groove, thereby locking the movable tube. The structure arranges the locking structure between the outer bushing and the inner bushing, and the outer bushing can provide a certain protection for the locking structure. The structure also has a simple and beautiful appearance, meets the requirements of simple design, and is suitable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS
