Rotary suction cup

Abstract

The rotary suction cup comprises a shell, a suction cup body is arranged at the lower end of the shell, and a rotary knob is rotationally arranged at the upper end of the shell; a limiting piece is arranged in the middle of the rotary knob, and a pair of spiral grooves is formed in the upper end of the limiting piece. The upper end of the suction cup penetrates through the shell and then is matched with the limiting piece through a rotating shaft, and the two ends of the rotating shaft are arranged on the corresponding spiral grooves. During use, the suction cup is tightly attached to a wall surface, so that air in the suction cup is exhausted from the periphery; then the knob is rotated, the knob drives the limiting piece to rotate, so that the rotating shaft moves upwards along the spiral groove, and the sucking disc is lifted upwards by the rotating shaft; the suction cup is firmly adhered to the wall surface, so that the adhesive force of the suction cup to the wall surface is improved, the suction cup has higher bearing capacity, and the situation that a suspended object falls off due to insufficient suction force is avoided.

Description

Technical Field

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

[0002] In daily life, it is often necessary to hang daily utensils on the wall, especially commonly used kitchen utensils and cleaning utensils. The existing hanging method often uses adhesive hooks to hang and fix daily utensils, that is, sticking the adhesive hooks on the wall and then hanging the utensils on the hooks.

[0003] This method mainly relies on the stickiness of the hook to bear the weight of the appliance. It cannot bear heavy objects and will fall off due to insufficient stickiness of the hook. At the same time, the hook can only be used once. Once it is moved, it will lose its stickiness and cannot be reused. Utility Model Content

[0027] Refer to the attached Figures 1 to 4 The utility model is further described in detail.

[0028] When the handle 31 is turned, the cam 31 is rotated to move the handle 32 so that the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam 31 is in a state of rotation and the cam

[0029] When the suction cup 2 is used, the suction cup 2 is first pressed against the wall to allow the air in the suction cup 2 to be discharged from the four sides of the bottom surface of the suction cup 2. Then, by rotating the knob 3, the knob 3 drives the limiter 31 to rotate, causing the rotating shaft 21 to move upward along the spiral groove 311, and the rotating shaft 21 lifts the suction cup 2 upward. This makes the suction cup 2 firmly adhere to the wall, improves the adhesion of the suction cup 2 to the wall, and makes the suction cup 2 have a stronger load-bearing capacity, thereby preventing the hanging object from falling off due to insufficient suction.

[0030] At the same time, when the hanging position needs to be changed, it is only necessary to rotate the knob 3 in the opposite direction to move the rotating shaft 21 from the high position of the thread groove to the low position. The return spring 4 in the shell 1 will press down the suction cup 2, and the suction cup 2 will stretch out to the surroundings, allowing external air to enter the suction cup 2, and the suction cup 2 can be separated from the wall; and it can be re-sucked to other required positions for repeated use.

[0031] In order to ensure that the bottom surface of the suction cup 2 can be firmly adhered to the wall, the upper end of the spiral groove 311 is provided with a positioning groove 3111 adapted to the rotating shaft 21. The positioning groove 3111 locks the rotating shaft 21 to the upper end of the spiral groove 311; it prevents the rotating shaft 21 from sliding off the spiral groove 311 by itself, thereby improving the stability of the suction cup 2 structure.

[0032] The knob 3 is provided with an installation cavity 32 for installing the limit member 31, and a plurality of slots 321 are provided on the side walls of the installation cavity 32; a plurality of clamping blocks 312 adapted to the slots 321 are provided on the outer side wall of the limit member 31, and the clamping blocks 312 are clamped in the slots 321 to clamp the limit member 31 and the knob 3; the knob 3 and the limit member 31 are provided separately, and are quickly assembled by cooperating with the clamping blocks 312 and the slots 321, thereby improving the production and assembly efficiency of accessories.

[0033] Another production method of the knob 3 and the limiter 31 is that the knob 3 and the limiter 31 are integrally formed; no additional assembly is required, thus reducing costs.

[0034] In order to increase the friction between the hand and the knob 3 , an anti-slip protrusion 33 is provided on the outer wall of the knob 3 .

[0035] The upper end surface of the shell 1 is provided with an inner guide protrusion 11 and an outer guide protrusion 12 from the inside to the outside, and the limit member 31 and the knob 3 rotate under the guidance of the inner guide protrusion 11 and the outer guide protrusion 12 respectively; so that the knob 3 can drive the limit member 31 to rotate stably along the outer guide protrusion 12 and the inner guide protrusion 11 to avoid jamming.

[0036] A decorative cover 13 is provided above the housing 1 to cover the hollow portion of the knob 3 , thereby preventing external dust from entering the suction cup 2 through the hollow portion of the knob 3 and improving the appearance of the suction cup 2 .

[0037] The lower end of the housing 1 is provided with a hanging portion 14 for hanging articles, which facilitates the hanging of articles.

[0038] The lower end of the suction cup 2 is provided with an acrylic adhesive block (the acrylic adhesive block is an existing adhesive). The acrylic adhesive can adhere the suction cup 2 to the wall, further improving the adhesion of the suction cup 2.

[0039] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
