Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and particularly relates to a hanging rack suction cup. Background Art

[0002] At present, in order to conveniently hang towels or other items in the bathroom, people generally install a hanging rack suction cup on the ceramic tile wall. The suction cup can adsorb on the wall, and the hanging rack can be used to hang towels. The structure of the hanging rack suction cup is relatively complex and the assembly is rather cumbersome, increasing the production cost. Content of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defects of the existing hanging rack suction cup with complex structure and cumbersome assembly, so as to provide a hanging rack suction cup with quick and convenient assembly.

[0004] To this end, the utility model provides a hanging rack suction cup, which comprises a rack body, a suction cup assembly and a knob assembly. The knob assembly includes a knob base and a knob cover. The knob base has a hollow second connecting column and a connecting block arranged on the outer wall of the second connecting column and extending outward. The second connecting column has a plurality of slots spaced along its outer wall, and a positioning protrusion is arranged on the outer wall of the connecting block; the knob cover has a first connecting cover, a second connecting cover and a hook connected in sequence. An insertion block adapted to be inserted into the slot is arranged on the inner wall of the first connecting cover, and a positioning hole adapted to the positioning protrusion is arranged on the inner wall of the second connecting cover.

[0005] The first connecting cover, the second connecting cover and the hook are integrally formed by injection molding.

[0006] The suction cup assembly includes a suction cup, a lifting rod and a pin shaft. The suction cup is arranged on the back of the rack body, and a lifting rod is vertically arranged in the middle thereof. The lifting rod sequentially passes through a second through hole of the rack body and a third through hole of the second connecting column. The pin shaft is fixed on the lifting rod, and its extending direction is perpendicular to the extending direction of the lifting rod. A slope cooperating with the pin shaft is arranged on the inner wall of the second connecting column, and a first step and a second step are arranged at both ends of the slope.

[0007] The height of the first step is higher than that of the second step, and a positioning groove adapted to the pin shaft is arranged between the slope and the first step.

[0008] The lifting rod is formed with a through hole for the pin shaft to pass through, and the second connecting column is formed with a notch corresponding to the through hole and for the pin shaft to be inserted into.

[0009] The technical solution of the utility model has the following advantages:

[0010] 1. The hanging rack suction cup provided by the present utility model, the knob assembly includes a knob base and a knob cover. The knob base has a hollow second connecting column, and a connecting block provided on the outer wall of the second connecting column and extending outward. The second connecting column has a plurality of slots spaced along its outer wall, and a positioning protrusion is provided on the outer wall of the connecting block; the knob cover has a first connecting cover, a second connecting cover and a hook connected in sequence. An insertion block adapted to be inserted into the slot is provided on the inner wall of the first connecting cover, and a positioning hole adapted to the positioning protrusion is provided on the inner wall of the second connecting cover. During assembly, the insertion block of the knob cover is inserted into the slot of the knob base, and the positioning hole of the second connecting cover is adapted to be connected with the positioning protrusion on the outer wall of the connecting block, so as to assemble the knob cover and the knob base together. By operating the knob cover, the knob base can be driven to rotate. The above-mentioned knob assembly has the advantages of simple structure and quick and convenient assembly.

[0011] 2. The hanging rack suction cup provided by the present utility model, the first connecting cover, the second connecting cover and the hook are integrally formed by injection molding. In this way, the knob cover can not only be used to drive the knob base to rotate, but also be used as a hook, having the advantage of simple structure.

[0012] 3. The hanging rack suction cup provided by the present utility model, the suction cup assembly includes a suction cup, a lifting rod and a pin shaft. The suction cup is provided on the back of the rack body, and a lifting rod is vertically provided in the middle thereof. The lifting rod sequentially passes through the second through hole of the rack body and the third through hole of the second connecting column. The pin shaft is fixed on the lifting rod, and its extending direction is perpendicular to the extending direction of the lifting rod. A slope cooperating with the pin shaft, and a first step and a second step provided at both ends of the slope are provided on the inner wall of the second connecting column. When the knob base rotates, the slope on the inner wall of the second connecting column slides relative to the pin shaft, so as to drive the lifting rod through the pin shaft to lift the middle part of the suction cup away from the adsorption surface, thereby forming a larger vacuum space and enhancing the adsorption capacity of the suction cup. Further, the height of the first step is higher than that of the second step, and a positioning groove adapted to the pin shaft is provided between the slope and the first step, so as to keep the lifting rod in the lifted position.
