Description

Technical Field

[0001] The utility model relates to the technical field of suction cups, and specifically relates to a rotary suction cup structure. Background Art

[0002] In daily life, it is often necessary to fix an attachment to the surface of another object through a suction cup; the suction cup can utilize the internal and external atmospheric pressure difference to firmly fix on the smooth surface of the object, and the adsorption position can be easily changed.

[0003] Currently, the suction cup structures on the market usually include a suction cup, a base, and a handle. A connecting column protrudes from the center of the suction cup. The free end of the connecting column passes through the cover body and is connected to the handle. During use, by pulling the handle towards the suction cup, the handle presses against the base and pulls up the center of the suction cup in the opposite direction, so as to generate a vacuum adsorption effect between the suction cup and the object surface.

[0004] However, the above suction cup structure still has the following problems in actual use. First, since the handle has a certain size, sufficient operating space is required during the pulling process. For some areas with limited operating environments, it is more troublesome to use, and the volume and thickness of such suction cup structures are relatively large, and the assembly is also more complex. Second, when using such a suction cup, the user must press the suction cup with one hand and pull the handle with the other hand to successfully drive the suction cup to generate an adsorption effect, which is also inconvenient in operation. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the defects of the above prior art and provide a rotary suction cup structure with a simple structure and convenient use.

[0006] The technical solution of the utility model is to provide a rotary suction cup structure with the following structure:

[0007] It includes a suction cup, a base, and a driving cover; a vertically upward extending connecting column is provided in the middle of the suction cup, a first through hole is provided in the middle of the base, a second through hole is provided in the middle of the driving cover, and the free end of the connecting column passes through the first through hole and the second through hole in sequence and is movably connected to the driving cover, so that the connecting column can rotate circumferentially relative to the driving cover; at least one lifting track extending along the circumferential direction of the base is provided on the top of the base, a lifting slope is provided on the lifting track, the first end of the lifting slope is flush with the top of the base, and the height of the lifting slope gradually rises from the first end to the second end; a slider is provided at the bottom of the driving cover, the lifting track is located on the movement track of the slider, and the slider abuts against the lifting slope of the lifting track; when the driving cover is screwed and driven to rotate circumferentially, the slider gradually rises along the lifting slope, and drives the middle part of the suction cup to move upward through the connecting column.

[0008] After adopting the above structure, the rotary suction cup structure in the utility model has the following advantages compared with the prior art:

[0009] When the user turns the drive cover, the drive cover will drive the slider to rotate in the circumferential direction and gradually rise along the lifting slope. When the drive cover and the slider rise, they will drive the middle part of the suction cup to rise through the connecting column, thereby causing the suction cup to produce vacuum adsorption. The rotary suction cup structure is easy to operate and has a simple structure. The suction cup can be adsorbed by simply rotating the drive cover, and the suction cup can be unlocked by rotating the drive cover in the opposite direction. The drive cover occupies a small space, which is convenient for operation in some places with small spaces.

[0010] Preferably, a positioning groove is provided at the second end of the lifting slope, and the shape of the positioning groove is adapted to the slider for the slider to be inserted therein.

[0011] The positioning groove has a positioning function. When the driving cover is rotated to make the slider fall into the positioning groove, it indicates that the driving cover is rotated into place, reminding the user to stop rotating the driving cover. The positioning groove can also limit the slider to prevent the suction cup from failing due to automatic resetting of the slider.

[0012] Preferably, a stopper is provided at the second end of the lifting slope to prevent the sliding block from falling off the lifting slope.

[0013] Preferably, there are four lifting rails, which are evenly spaced along the circumferential direction of the base; there are also four sliders, which correspond to the four lifting rails one by one. This can make the force on the drive cover more stable and the user can rotate it more labor-saving.

[0014] Preferably, a radially extending pin is connected to the free end of the connecting column, the pin is located above the second through hole, and the length of the pin is greater than the inner diameter of the second through hole.

[0015] Preferably, a spring is sleeved on the connecting column, one end of the spring abuts against the suction cup, and the other end abuts against the base. When the user rotates the drive cover to gradually raise the slider along the lifting slope, the spring will be compressed; when the user reversely rotates the drive cover to reset the slider, the spring will push the middle of the suction cup to ensure that the suction cup can be reset.

[0016] Preferably, a groove is provided at the top of the driving cover, and a cover plate is detachably connected to the top of the groove; the pin is located in the groove and is provided with a gap from the bottom of the cover plate. The cover plate does not affect the relative rotation between the pin and the driving cover, and can hide the pin, making the overall product more concise and beautiful.

[0027] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the utility model discloses a rotary suction cup structure: comprising a suction cup 1, a base 2 and a driving cover 3; a connecting column 11 extending vertically upward is provided in the middle of the suction cup 1, a first through hole 21 is provided in the middle of the base 2, a second through hole 31 is provided in the middle of the driving cover 3, and the free end of the connecting column 11 passes through the first through hole 21 and the second through hole 31 in sequence and is movably connected with the driving cover 3, so that the connecting column 11 can rotate relative to the driving cover 3 in the circumferential direction. Among them, the first through hole 21 is square, and the cross section of the connecting column 11 is also square, matching the first through hole 21, and the connecting column 11 and the base 2 can move up and down relative to each other, but cannot rotate relative to each other in the circumferential direction.

[0028] The top of the base 2 is provided with at least one lifting track 22 extending in the circumferential direction of the base 2, and the lifting track 22 is provided with a lifting slope 221; one end of the lifting slope 221 is set as the first end, and the other end is set as the second end, so that the first end of the lifting slope 221 is flush with the top of the base 2, and the height of the lifting slope 221 gradually rises from the first end to the second end. A slider 32 is provided at the bottom of the driving cover 3, and the lifting track 22 is located on the movement track of the slider 32, and the slider 32 is against the lifting slope 221 of the lifting track 22; when the driving cover 3 is screwed and the slider 32 is driven to rotate circumferentially, the slider 32 gradually rises along the lifting slope 221, and drives the middle part of the suction cup 1 to move upward through the connecting column 11.

[0029] When the rotary suction cup structure of the utility model is in use, the user only needs to screw the driving cover 3, and the driving cover 3 will drive the slider 32 to rotate in the circumferential direction and gradually rise along the lifting inclined surface 221. When the driving cover 3 and the slider 32 rise, they will drive the middle part of the suction cup 1 to rise through the connecting column 11, thereby causing the suction cup 1 to produce vacuum adsorption. The driving cover 3 can be rotated in the reverse direction to complete the unlocking of the suction cup 1. The rotary suction cup structure is easy to operate and has a simple structure. The driving cover 3 occupies a small space, which is convenient for operation in some places with narrow spaces.

[0030] A positioning groove 222 is formed at the second end of the lifting inclined surface 221 . The shape of the positioning groove 222 matches the slider 32 , so that the slider 32 can be inserted therein.

[0031] The positioning groove 222 has a positioning function. When the driving cover 3 is rotated to make the slider 32 fall into the positioning groove 222, it indicates that the driving cover 3 is rotated into place, reminding the user to stop rotating the driving cover 3. The positioning groove 222 can also limit the slider 32 to prevent the suction failure of the suction cup 1 due to the automatic resetting of the slider 32.

[0032] A stopper 223 is disposed at the second end of the lifting inclined surface 221 to prevent the slider 32 from escaping from the lifting inclined surface 221 .

[0033] There are four lifting tracks 22, which are evenly spaced along the circumferential direction of the base 2; there are also four sliders 32, which correspond to the four lifting tracks 22 one by one, so that the force on the driving cover 3 is more stable and it is more labor-saving for the user to rotate.

[0034] A radially extending pin shaft 12 is connected to the free end of the connecting column 11. The pin shaft 12 is located above the second through hole 31, and the length dimension of the pin shaft 12 is greater than the inner diameter dimension of the second through hole 31 to prevent the free end of the connecting column 11 from disengaging from the second through hole 31.

[0035] A spring 13 is sleeved on the connecting column 11. One end of the spring 13 abuts against the suction cup 1, and the other end abuts against the base 2. When the user screws the driving cover 3 to gradually raise the slider 32 along the lifting inclined surface 221, the spring 13 will be compressed; when the user reversely screws the driving cover 3 to reset the slider 32, the spring 13 will push the middle of the suction cup 1 to ensure that the suction cup 1 can be reset.

[0036] A groove 33 is provided at the top of the driving cover 3. The top of the groove 33 is detachably connected with a cover plate 34 through a buckle; the pin shaft 12 is located in the groove 33 and is arranged with a gap from the bottom of the cover plate 34. The cover plate 34 does not affect the relative rotation of the pin shaft 12 and the driving cover 3, and can hide the pin shaft 12, making the overall product more concise and beautiful.

[0037] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
