[0002] The suction cup hook is a commonly used daily necessity. After pressing the flexible suction cup on the hook body against a smooth plane, the vacuum adsorption is realized through the restoring force of the flexible suction cup itself, so that the main body hook is stably fixed on the smooth plane.

[0003] However, only relying on the restoring force of the flexible suction cup itself to achieve vacuum adsorption, the adsorption force is small, and it is laborious to remove the flexible suction cup. Therefore, designing a suction cup hook with large adsorption force and convenient disassembly and assembly is an urgent problem to be solved in this industry. Summary of the Utility Model

Detailed Embodiment

[0027] The following further describes the utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the utility model.

[0028] Embodiment. A suction cup hook has a structure as Figures 1 to 6 shown, including a main body 1; a flexible suction cup 2 is closely arranged on the back of the main body 1, a connecting shaft 3 passing through the main body 1 is vertically connected to the middle of the flexible suction cup 2, and a round rod 4 horizontally arranged on the front of the main body 1 is connected to the end of the connecting shaft 3; a spring 5 is sleeved outside the connecting shaft 3, and both ends of the spring 5 are respectively in contact with the back of the main body 1 and the flexible suction cup 2; a receiving cavity 6 is arranged at the position corresponding to the middle of the flexible suction cup 2 on the back of the main body 1, a cover plate 7 is connected to the front of the main body 1, and a vertically arranged slider 8 is slidably arranged between the cover plate 7 and the front of the main body 1; an inclined sliding table 9 with a protruding top is arranged at the position corresponding to the round rod 4 on the slider 8, and a sliding groove 10 is arranged at the position corresponding to the connecting shaft 3 on the inclined sliding table 9; a hook 11 is connected to the bottom end of the slider 8.

[0029] The side wall of the accommodation cavity 6 is disposed opposite to the edge position of the flexible suction cup 2, and a raised retaining ring 12 is arranged in the accommodation cavity 6; a gap 13 is provided between the retaining ring 12 and the side wall of the accommodation cavity 6, and the height of the retaining ring 12 is lower than that of the side wall of the accommodation cavity 6; the distance of the gap 13 is 3-8 mm; the difference between the height of the retaining ring 12 and the height of the side wall of the accommodation cavity 6 is 1-3 mm; two clamping plates 14 with clamping heads are connected to the cover plate 7, and the two clamping plates 14 are slidably attached to both sides of the slider 8; a clamping hole 15 is provided on the main body 1 corresponding to the position of each clamping plate 14; a first limiting groove 16 for cooperating with the end of the connecting shaft 3 is provided at the top of the chute 10; a second limiting groove 17 for cooperating with the round rod 4 is provided at the top of the inclined slide 9; a raised reinforcing block 18 is provided on the flexible suction cup 2 corresponding to the connection part thereof with the connecting shaft 3; a sliding clamping groove 19 is provided on the front surface of the bottom of the slider 8, and a clamping piece 20 is connected to the bottom of the sliding clamping groove 19; a clamping groove 21 for cooperating with the clamping piece 20 is provided on the hook 11.

[0030] Working principle: When in use, it is necessary to closely attach the flexible suction cup 2 to a smooth plane, and then pull the slider 8 downward. The inclined slide 9 on the slider 8 will slide downward relative to the round rod 4 until the end of the connecting shaft 3 slides along the chute 10 into the first limiting groove 16 at the top, and the round rod 4 at the end of the connecting shaft 3 slides into the second limiting groove 17 at the top of the inclined slide 9; at this time, the inclined slide 9 with a raised top can push the horizontal round rod 4 outwards, and the round rod 4 pulls the middle part of the flexible suction cup 2 to deform into the accommodation cavity 6 and compress the spring 5 through the connecting shaft 3, so that a large adsorption force can be generated between the flexible suction cup 2 and the smooth plane. Since the end of the connecting shaft 3 is stuck in the first limiting groove 16 and the round rod 4 is stuck in the second limiting groove 17, it is difficult to pull the connecting shaft 3 under the action of the restoring force of the flexible suction cup 2 and the spring 5, and the relative position between the slider 8 and the main body 1 can be kept stable, and the flexible suction cup 2 can stably adsorb on the smooth surface. Subsequently, an object can be hung on the hook 11 at the bottom end of the slider 8.

[0031] When it is necessary to remove the main body 1 from the smooth plane, only need to push the slider 8 upward. Under the action of the restoring force of the spring 5, the round rod 4 will slide downward along the inclined slide 9, the connecting shaft 3 moves towards the smooth plane to reset, and the middle part of the flexible suction cup 2 also approaches the smooth plane synchronously, so that the adsorption force between the flexible suction cup 2 and the smooth plane is small, and the user can conveniently remove the flexible suction cup 2 from the smooth plane.

[0032] Since a raised reinforcing block 18 is provided at the connection part of the flexible suction cup 2 and the connecting shaft 3, this part is not easily damaged during the pulling and resetting processes and has good durability; the cover plate 7 is detachably connected to the main body 1 through the clamping heads at the tops of the two clamping plates 14 and the clamping holes 15 on the main body 1, and the disassembly and assembly of the cover plate 7 are relatively convenient; at the same time, the two clamping plates 14 are limitedly arranged on both sides of the slider 8, so that the slider 8 can slide vertically more stably.

[0033] The side wall of the accommodation cavity 6 on the back of the main body 1 is disposed opposite to the edge position of the flexible suction cup 2, so that the connecting shaft 3 can more easily and to a greater extent pull the flexible suction cup 2 to deform, thereby improving the adsorption force; a retaining ring 12 is arranged in the accommodation cavity 6, and a gap 13 is provided between the retaining ring 12 and the side wall of the accommodation cavity 6. The height of the retaining ring 12 is slightly lower than the height of the accommodation cavity 6, so that when the connecting shaft 3 pulls the middle part of the flexible suction cup 2, the edge of the flexible suction cup 2 is not easily slipped into the accommodation cavity 6 and stuck, and the structural stability is relatively high.

[0034] The user can realize the connection between the hook 11 and the slider 8 by snapping the clamping groove 21 on the hook 11 into the clamping piece 20 from the sliding clamping groove 19; the hook 11 only needs to be pulled upward along the sliding clamping groove 19 to be separated from the slider 8, making the replacement and maintenance operations of the hook 11 relatively convenient.
