Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] This utility model provides a vacuum cleaner hose connection structure. Please refer to [link / reference]. Figure 1-9 The connector body includes a main body and a mating component.

[0031] The main body includes a first shell 1 and a second shell 2, which are hinged together, and the opening between the first shell 1 and the second shell 2 is provided with a snap-fit ​​structure.

[0032] The inner wall of the first housing 1 is integrally provided with an inner tube 3, and the inner wall of the first housing 1 is integrally provided with a first arc-shaped pressing plate 11, and the inner wall of the second housing 2 is integrally provided with a second arc-shaped pressing plate 21.

[0033] The buckle structure includes a first support strip 12 integrally formed at one end of the first housing 1 and a second support strip 22 integrally formed at one end of the second housing 2;

[0034] The second support bar 22 is hinged to an L-shaped buckle bar 4 by a pin. The end of the L-shaped buckle bar 4 has a protrusion 41, and the first support bar 12 has a slot 121.

[0035] A first rubber strip 111 is bonded to the inner wall of the first arc-shaped clamping plate 11, and there is a gap 5 between the first rubber strip 111 and the inner tube 3. A second rubber strip 211 is bonded to the inner wall of the second arc-shaped clamping plate 21, and there is also a gap 5 between the second rubber strip 211 and the inner tube 3. The first rubber strip 111 and the second rubber strip 211 clamp the hose sleeved on the inner tube 3.

[0036] The first housing 1 has a first hinge block integrally formed at one end, and the second housing 2 has a second hinge block integrally formed at one end. The first hinge block and the second hinge block are hinged together by a pin.

[0037] The bottom of the inner tube 3 has an integral arc-shaped bridging piece 300, which is welded to or integrally formed with the inner wall of the first housing 1.

[0038] The mating part is configured as an external threaded connector 31. The end of the inner tube 3 is integrally equipped with an external threaded connector 31. At this time, the external threaded connector 31, which serves as the mating part, forms a male connector with the main body.

[0039] The mating component is configured as an internally threaded connector 32, and the end of the inner tube 3 is integrally equipped with an internally threaded connector 32. In this case, the internally threaded connector 32, which serves as the mating component, forms a female connector with the main body. The female connector can be threadedly connected to the male connector; thus, the connection between hoses can be achieved through the female connector and the male connector.

[0040] In practical use:

[0041] Fit the hose onto the inner tube 3, and clamp the hose tightly with the first rubber strip 111. Figure 4 As shown, rotate the second housing 2 to the position shown. Figure 1 As shown, the second housing 2 is pressed down until the second rubber strip 211 compresses the hose (at this time, the second rubber strip 211 deforms), and the L-shaped buckle strip 4 is rotated until the protrusion 41 is inserted into the slot 121, thereby realizing the quick connection of the hose.

[0042] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
