[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, wherein the same components are represented by the same reference numerals.
[0018] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0019] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0020] like Figures 1 to 5 As shown, a connector for a drainage tube with an adjustable fixed head size comprises a connecting tube (1), wherein the connecting tube (1) is provided with an adjusting mechanism (2).
[0021] The adjustment mechanism (2) comprises an elastic hose (201), the elastic hose (201) being sleeved on the outside of the connecting pipe (1), an adjustment sleeve (202) being connected to the outside of the elastic hose (201), adjustment grooves (203) being evenly provided at both ends of the adjustment sleeve (202), a fixed sleeve (204) being connected to the outside of the adjustment sleeve (202), two support plates (205) being fixedly connected to the outside of the fixed sleeve (204), threaded rods (206) being connected to the two support plates (205), one end of the threaded rod (206) extending to the outside of one of the support plates (205), a moving part (207) being provided on the outside of the threaded rod (206), and an end of the moving part (207) being threadedly connected to the threaded rod (206). By twisting the moving part 207 to rotate on the threaded rod 206, the fixed sleeve 204 is squeezed toward the center. At this time, the adjusting sleeve 202 is squeezed along the adjusting groove 203, and then the elastic hose 201 is squeezed to adjust the aperture size of the connecting pipe according to the size of the drainage pipe opening.
[0022] The outer side of the movable member (207) is provided with an anti-skid groove (208). The anti-skid groove 208 increases friction and prevents the hand from slipping when twisting.
[0023] The elastic hose (201) is made of thermoplastic polyurethane material. The elastic hose 201 is made of thermoplastic polyurethane material. This material has good elasticity and wear resistance, can maintain good performance under repeated extrusion and deformation, and prolong the service life of the connecting pipe 1.
[0024] The adjustment sleeve (202) is made of polyethylene material. Polyethylene material has good flexibility and corrosion resistance and can adapt to different use environments.
[0025] The fixing sleeve (204) is made of polycarbonate material. Polycarbonate material has high strength and high heat resistance, and can provide stable fixing support for the connecting pipe 1.
[0026] Working principle: By twisting the movable part 207 to make it rotate on the threaded rod 206, the fixed sleeve 204 is squeezed toward the center. At this time, the adjusting sleeve 202 is squeezed along the adjusting groove 203, and then the elastic hose 201 is squeezed to adjust the aperture size of the connecting pipe according to the size of the drainage pipe opening.
[0027] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
