Description

TECHNICAL FIELD

[0001] The utility model relates to hook technical field especially relates to a suction cup hook. BACKGROUND

[0002] At present, some hooks appear on the market for hanging face basin, towel, bath ball and other daily necessities. For example, the Chinese patent with the application number 202223019512.1 discloses a suction cup fixed type basin hook, which comprises a hook, the hook can be fixed on the external base surface, further comprises a suction cup, the hook is connected with the suction cup, the suction cup comprises a disc body, a framework and a disc cover, the disc body is covered on the framework, and a connecting part is arranged on the framework.

[0003] When the suction cup is used, the suction cup is directly pressed on the glass or wall to realize adsorption, but the adsorption force of such suction cup is small, so heavy objects cannot be hung on the hook, otherwise the whole hook will fall off from the wall or glass. UTILITY MODEL CONTENT

[0004] In order to solve the problems in the prior art, a suction cup hook with improved adsorption force is provided.

[0005] The utility model adopts the following technical scheme to realize it: a suction cup hook, comprising:

[0006] A base is provided with a hook on the outer side wall, and a driving member is arranged on the inner wall of the base;

[0007] A suction cup is arranged at the bottom of the base, an axial extension linkage member is arranged at the center of the suction cup, a radial extension convex shaft is arranged on the circumferential side wall of the linkage member; and

[0008] A linkage disc is rotationally connected to the base, a through hole is arranged at the center of the linkage disc for inserting the linkage member, the inner wall of the through hole is provided with a linkage surface with height difference, the convex shaft is in contact with the linkage surface and can slide relative to each other, abutting members are arranged on the side wall of the linkage disc in the circumferential direction, and the abutting members are located on the rotation path of the driving member;

[0009] When the base rotates in the positive direction, the driving member can abut against the abutting member, the base is in actual rotation and can drive the linkage disc to rotate; when the base rotates in the reverse direction, the driving member cannot abut against the abutting member, the base is in idle rotation and cannot drive the linkage disc to rotate.

[0010] In use, the suction cup is pressed on the wall or glass that needs to be adsorbed. After the suction cup is preliminarily fixed, the linkage and the suction cup cannot rotate, at this time the user can rotate the base in the positive direction, at this time the driving part abuts against the abutting part, at this time the base drives the linkage disc to rotate in the positive direction; the rotation of the linkage disc causes the linkage surface to slip relative to the convex shaft, because of the height difference of the linkage surface, the convex shaft moves from the low position of the linkage surface to the high position of the linkage surface, at this time the linkage moves from low to high, so that the center of the suction cup is pulled up to form a vacuum negative pressure, thereby greatly enhancing the adsorption force of the suction cup. Then rotate the base in the reverse direction, so that the hook is rotated to the position in the vertical direction, at this time the driving part cannot abut against the abutting part, thereby realizing the idling of the base, and the convex shaft can be kept at the high position of the linkage surface, and the suction force of the suction cup remains unchanged. When it is necessary to remove the suction cup, the user rotates the base in the positive direction again, so that the driving part abuts against the abutting part and continues to drive the linkage disc to rotate, so that the linkage surface rotates from the high position to the low position, so that the convex shaft is located at the low position, at this time the linkage descends, the vacuum at the center of the suction cup disappears, at this time the user can remove the suction cup.

[0011] Among them, the linkage surface is a continuous surface.

[0012] Among them, the abutting of the driving part and the abutting part means that the driving part is abutted by the abutting part; the non-abutting of the driving part and the abutting part means that the driving part is not abutted by the abutting part, which has two situations, one is that the driving part does not contact the abutting part at all, the other is that the driving part contacts the abutting part but is not abutted by the abutting part.

[0013] The present scheme drives the linkage disc to rotate through the actual rotation of the base, and realizes that the center of the suction cup is pulled up to form a vacuum environment through the cooperation of the convex shaft and the linkage surface, thereby greatly enhancing the suction force of the suction cup. At the same time, the base can also idle, the hook can be moved to be parallel to the direction of gravity, and the suction force of the suction cup will not change, so that the suction cup remains in a state of large suction force, thereby the heavy object can be hung.

[0014] As a preferred, the circumferential two sides of the abutting part are respectively provided with a first abutting surface and a first contact surface, the first abutting surface can abut against the driving part rotating in the positive direction, and the first contact surface can contact the driving part rotating in the reverse direction; when the base rotates in the reverse direction, the driving part can pass through the abutting part after contacting the first contact surface.

[0015] When the base rotates in the reverse direction, the driving part can pass through the abutting part after contacting the first contact surface, so that the hook can rotate in the reverse direction infinitely when the base idles, so as to facilitate the adjustment of the position of the hook.

[0016] As a preferred, one end of the driving part away from the linkage disc is fixed with the base, and the other end close to the linkage disc is not fixed with the base, so that the driving part can deform to pass through the abutting part.

[0017] The driving member has deformability, so that when the base is idling, the driving member can easily pass the abutting member, facilitating adjustment of the hook position.

[0018] Preferably, the driving member is inclined and overall biased to the positive direction of rotation of the base.

[0019] With the above arrangement, the driving member can better abut against the abutting member when moving in the positive direction, and can better deform to pass the abutting member when rotating in the reverse direction.

[0020] Preferably, the driving member is provided with a second abutting surface for abutting against the first abutting surface and a second contact surface for contacting the first contact surface on the two sides in the circumferential direction; the first abutting surface and the second abutting surface are both vertical surfaces extending in the radial direction, and the first contact surface and the second contact surface are both inclined surfaces deviating from the radial direction and both are rounded transitions.

[0021] The vertical surfaces can firmly realize abutment between them, and the inclined surfaces and rounded transitions can make them mutually separate after contact.

[0022] Preferably, the outer side wall of the linkage disc is provided with a gear ring, the gear ring is arranged between two adjacent abutting members, and the driving member can contact the gear ring.

[0023] When the base rotates, the driving member contacts the gear ring, so that the driving member hits the gear ring and makes a "clicking" sound to prompt the user to rotate. Wherein, whether the base is actually rotating or idling, the driving member will contact the gear ring.

[0024] Preferably, the linkage surface is provided with a groove at least at the high position thereof.

[0025] The groove makes the convex shaft not easily deviate when at the high position of the linkage surface, so as to keep the suction cup in a state of greater suction force.

[0026] Preferably, the upper end of the linkage disc is matched with a limiting block, the limiting block is provided with a matching limiting surface above the linkage surface, and the limiting surface and the linkage surface form a slide groove with a height difference therebetween.

[0027] By forming the slide groove between the limiting surface of the limiting block and the linkage surface, the entire up-and-down position of the convex shaft is completely limited, ensuring the stability of the movement of the convex shaft.

[0028] Preferably, the upper end of the linkage disc is matched with a limiting block, the limiting block is provided with a matching limiting surface above the linkage surface at least at the low position, and the limiting surface and the linkage surface form a slide groove therebetween.

[0029] When the convex shaft is in the high position of the linkage surface, the center of the suction cup has a vacuum environment, when the linkage surface rotates so that the convex shaft changes from the high position to the low position, the linkage member may not immediately drop, therefore, the convex shaft is pressed down by the limiting surface, so that the convex shaft enters the low-position sliding groove, so that the suction cup is in contact with the adsorption state.

[0030] As preferred, the base is matched with a shell, the shell is sleeved on the base, and the shell and the base are clamped and matched.

[0031] The clamped and matched shell and base can realize synchronous rotation.

[0032] Compared with the prior art, the utility model has the advantages that the base drives the linkage disc to rotate, the convex shaft and the linkage surface are matched to pull up the center of the suction cup to form a vacuum environment, so that the suction force of the suction cup is greatly enhanced.
