DETAILED DESCRIPTION

[0024] In the embodiment, the rotating suction disc type magnetic attraction support comprises a suction disc assembly and a magnetic attraction assembly 7, and the magnetic attraction assembly 7 is movably connected with the suction disc assembly; the suction disc assembly comprises a suction disc 1, a gland 2, a rotating cover 3 and a lifting disc 5; the suction disc 1 is connected with a fixed column 11; the gland 2 is arranged above the suction disc 1; the rotating cover 3 is movably arranged above the gland 2 and presses the gland 2, and the rotating cover 3 can rotate relative to the gland 2; the lifting disc 5 is arranged on the rotating cover 3 and is connected with the fixed column 11 penetrating through the gland 2 (screw locking can be used); an arc-shaped guide groove 31 is arranged in the rotating cover 3, and the guide groove 31 has a structure that gradually becomes shallower from deep to shallow; an arc-shaped lifting head 51 protruding towards the guide groove 31 is arranged at a position of the bottom surface of the lifting disc 5 opposite to the guide groove 31, and the lifting head 51 is embedded in the guide groove 31; the lifting disc 5 is lifted by rotating the rotating cover 3 to make the lifting head 51 push the position of the guide groove 31 that is gradually shallower; the suction disc 1 is pulled tight by the fixed column 11 to generate adsorption force and be tightly adsorbed on an attached surface (such as glass); and the gland 2 tightly presses the periphery of the suction disc 1.

[0025] The guide groove 31 is gradually shallower from the head to the tail, and the depth of the avoiding hole 32 is greater than the depth of the head of the guide groove 31. The depth of the positioning groove 33 is greater than the depth of the tail of the guide groove 31. When the rotating cover 3 is rotated to make the jacking head 51 slide into the avoiding hole 32, the suction cup 1 is loosened, and the suction cup 1 can be easily removed. When the rotating cover 3 is rotated to make the jacking head 51 slide into the positioning groove 33, the suction cup 1 is tightened and positioned. The suction cup 1 is tightly attached to the attachment surface due to the negative pressure.

[0026] The spring groove 12 is arranged around the fixed column 11 on the suction cup 1, and the spring 4 is arranged in the spring groove 12. When the suction cup 1 is pulled by the lifting disc 5, the spring is compressed by the compression cover. When the suction cup 1 is loosened, the spring quickly resets the suction cup 1 by the elastic force, facilitating disassembly.

[0027] A compression ring 21 is arranged along the edge of the compression cover 2, and the compression ring 21 protrudes towards the rotating cover 3. The bottom edge of the rotating cover 3 is pressed against the edge of the compression ring 21.

The rotating cover 3 is installed with the marble assembly 8 with a marble and a compression spring through the spring column 36. When the rotating cover 3 is rotated, the marble is pressed into any limiting groove 63 to realize the positioning of the rotating cover 3, so that the rotating cover 3 will not be randomly rotated. At the same time, when the marble is pressed into the limiting groove 63, a rhythmic sound of “dada, dada, dada” is produced, which can achieve a certain pressure reduction effect.

[0029] The top surface of the compression cover 2 is embedded in the central area of the rotating cover 3. Three guide columns 22 are arranged on the top surface of the compression cover 2. Guide sleeves 62 are arranged on the bottom surface of the surface shell 6 in alignment with the positions of the guide columns 22. The guide columns 22 are inserted into the guide sleeves 62 through the lifting disc 5 and can be locked by screws.

Four stop blocks 34 arranged in a cross shape are arranged in the rotating cover 3. The limiting arms 53 and the stop blocks 34 form a limiting structure for the rotating range of the rotating cover 3. A plurality of outwardly protruding knobs 35 are arranged on the outer side wall of the rotating cover 3, which facilitates the force receiving of the hand when the rotating cover 3 is rotated.

[0031] The shaft seat 61 is arranged on the surface shell 6, and the rotating arm 71 is installed on the shaft seat 61 through a rotating shaft, and the magnetic attraction assembly 7 is hinged with the rotating arm 71 so as to be able to rotate.

[0032] The surface cover 9 is arranged in the central region of the surface shell 6, and the hole of the alignment guide sleeve 62 is covered by the surface cover 9, so as to play a protection and decoration effect.

[0033] The guide grooves 31 include two, and the two guide grooves 31 form a central symmetry structure along the center of the rotating cover 3.

[0034] The above has made a detailed description of the utility model, the above is only a preferred embodiment of the utility model, and cannot limit the utility model implementation range, namely, all equivalent changes and modifications made according to the application range should still belong to the utility model coverage.
