Description

Technical Field

[0001] The utility model relates to the field of household products, in particular to a hook. Background Art

[0002] Existing hooks generally have self-adhesive stickers on the back, or use nail-free glue, or are fixed by suction cup adsorption. At present, the hook fixed by the suction cup is generally hinged by the pull rod between the hook body and the suction cup, and the eccentricity is generated by flipping the hook body to pull the pull rod to make the suction cup generate vacuum to achieve adsorption. This structure has poor stability. The hook body is prone to reverse flipping due to displacement and other problems during use, resulting in vacuum failure and falling off. At the same time, the traditional suction cup has high requirements on the surface roughness of the adsorption surface and has poor usability. Utility Model Content

[0003] Based on the above problems, the utility model aims to provide a hook which is easy to install and can be fixed stably and firmly.

[0004] In view of the above problems, the following technical solutions are provided: a hook comprises a main body, a suction cup is provided on the back of the main body, a hook body is provided on the front of the main body, a suction cup installation position is also provided on the back of the main body, the suction cup installation position is provided with a support tube extending toward the back of the main body, and the suction cup installation position is also provided with a pulling hole arranged concentrically with the support tube and penetrating the main body; the front of the suction cup is abutted against the end face of the extended end of the support tube near the outer edge, and a screw rod passing through the pulling hole is provided at the center of the front of the suction cup; the front of the main body is also provided with a knob cooperating with the screw thread, and the knob pulls the screw by rotating to form a negative pressure between the concave center position of the back of the suction cup and the adsorbed surface.

[0005] In the above structure, the suction cup is fixedly connected to the screw by injection molding, and the knob pulls the screw by rotating to form negative pressure between the concave center position of the back of the suction cup and the adsorbed surface. At the same time, the end face of the support tube and the front side of the suction cup near the outer edge are abutted against each other to provide support for the outer edge of the suction cup, thereby effectively establishing a negative pressure space, which is beneficial to improving the overall adsorption strength of the suction cup. Since the adsorption of the suction cup is produced by the threaded cooperation of the screw and the knob, the screw can generate sufficient pulling force to ensure the negative pressure, and can also effectively avoid the falling-off phenomenon caused by the displacement of the hook body in the prior art.

[0006] The utility model is further configured that a positioning edge convex outwardly away from the back side of the suction cup is provided at the outer edge of the front side of the suction cup, and the support tube abuts against the front side of the suction cup inside the positioning edge.

[0007] In the above structure, the suction cup becomes concave in the middle when pulled by the screw, which will cause the outer diameter of the suction cup to shrink and then break away from the support of the end face of the support tube. Therefore, a positioning edge is provided to cooperate with the support tube, and the cooperation between the support tube and the positioning edge can be used to limit the reduction of the outer diameter of the suction cup.

[0008] The utility model is further configured such that the suction cup installation position is located at an upper end of the main body; and the hook body is located at a lower end of the main body.

[0009] In the above structure, the center of gravity of the hook body under the load state is effectively lowered to increase the adsorption strength of the suction cup.

[0010] The utility model is further configured that an adhesive layer is provided on the back of the suction cup.

[0011] In the above structure, the softness of the adhesive layer is greater than that of the suction cup, so it can effectively improve the fit between the adhesive layer and the adsorbed surface, improve the air tightness, and at the same time use its own viscosity to improve the load strength.

[0012] The utility model is further configured that a support portion is provided at a lower end position on the back side of the main body.

[0013] In the above structure, the hook body is in a load-bearing state and abuts against the adsorbed surface through the supporting part.

[0014] The utility model is further configured such that a surface of the support portion facing away from the front surface of the main body and a back surface of the suction cup are located in the same plane.

[0015] In the above structure, the force stability of the suction cup is improved.

[0016] The utility model is further configured that an adhesive layer is provided on the back of the suction cup, and a surface of the support portion facing away from the front of the main body and a surface of the adhesive layer facing away from the suction cup are located in the same plane.

[0017] In the above structure, the force stability of the suction cup is improved, and the softness of the adhesive layer is greater than that of the suction cup, so it can effectively improve the fit between the suction cup and the adsorbed surface, improve the air tightness, and at the same time use its own viscosity to increase the load strength.

[0018] The utility model is further configured that the front side of the main body is provided with a hook installation part extending upward and spaced apart from the front side of the main body; the hook body is provided with an inserting part, and the inserting part is sleeved on the hook installation part.

[0019] In the above structure, the hook body and the main body are detachably arranged, which is convenient for replacement. At the same time, the overall size is effectively reduced in the disassembled state, which is conducive to reducing the packaging volume.

[0020] The utility model is further configured that an anti-detachment hook is provided at the upper end of the hook mounting portion, and when the plug-in portion is sleeved on the hook mounting portion, the anti-detachment hook passes through the upper end of the plug-in portion.

[0021] In the above structure, the anti-drop hook can assist the plug-in sleeve in preventing it from dropping off, thereby preventing the hook body from accidentally falling off.

[0022] The beneficial effects of the utility model are as follows: the suction cup is fixedly connected to the screw by injection molding, and the knob pulls the screw by rotating to form negative pressure between the concave center position of the back side of the suction cup and the adsorbed surface, while the end face of the support tube abuts against the front side of the suction cup near the outer edge to provide support for the outer edge of the suction cup, effectively establishing a negative pressure space, which is beneficial to improving the overall adsorption strength of the suction cup; since the adsorption of the suction cup is produced by the threaded cooperation of the screw and the knob, the screw can generate sufficient pulling force to ensure the negative pressure, and can also effectively avoid the falling-off phenomenon caused by the displacement of the hook body in the prior art.
