Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a structure for connecting suction cups. Background Art

[0002] Nowadays, in order to pursue a tidy space, people will use various storage tools to store and organize items. At the same time, in order to save space and facilitate organization, they will hang the tools. Therefore, many items will have a receiving part or a hanging hole. For example, storage racks and storage shelves are equipped with hanging holes connected to external bolts. Generally, it is necessary to drill holes in the wall to install screws, and then hang the storage baskets, storage shelves, etc. on the screws. Therefore, the wall needs to be destroyed during installation, and specific tools are required, making the installation more troublesome. Or use screw traceless stickers, stick the traceless stickers on the wall, install items such as shelves and mop buckets, and realize the hanging and fixing of hooks, shelves, mop buckets and other items. However, the connection between the traceless stickers and screws only relies on the mutual resistance between the screw cap and the traceless stickers, making the load-bearing capacity relatively weak. At the same time, after the traceless stickers are used for a long time, the adhesive on the back will age and become brittle, and it will lose its stickiness and fall off. At the same time, the suction cup expels the internal air by pressing to form a vacuum cavity, and is fixed to the base surface by the internal and external pressure difference. It is widely used as a simple and durable hanging object. In particular, in order to improve the fixing effect of the suction cup and prevent the suction cup from falling off the base surface, suction cups with frames are widely used. The plate body of this suction cup is made of a frame wrapped in rubber, a plate cover is provided outside the plate body, and a connecting part is provided on the plate body, which is used to connect objects that need to be wall-mounted. However, there is currently no structure suitable for connecting objects with hanging holes and suction cups. Utility Model Content

Preferably, 1-2 fixing components are provided. The fixing assembly includes a connecting column 4 and a fastener 5. The connecting column 4 is arranged on the side of the receiving part 3 away from the suction cup and protrudes from the surface of the receiving part 3. The connecting column 4 is a metal rod and a clamping edge 41 is arranged at one end of the connecting column 4. After the connecting column 4 passes through the receiving part 3, the clamping edge 41 abuts against the inner wall of the receiving part 3, and the outer diameter of the clamping edge 41 is larger than the outer diameter of the connecting column 4, so as to enhance the connection between the connecting column 4 and the receiving part 3 and prevent the connecting column 4 from falling. The surface of the connecting column 4 is provided with an external thread, and the fastener 5 is screwed and fixed on the connecting column 4. After the connecting column 4 passes through the hanging object, the fastener 5 is screwed and fastened on the connecting column, and the hanging object can be fixed and hung through the suction cup. The overall structure is simple and easy to use. Furthermore, the fastener 5 is a mushroom cap 51 with an internal thread. The smooth arc-shaped mushroom cap can cover and wrap the end of the connecting column 4 to prevent the end of the connecting column 4 from scratching the hanging object; a hexagonal nut 52 is provided at the opening of the mushroom cap 51, and the hexagonal nut can conveniently screw the fastener 5 to the connecting column 4.

[0051] In a preferred case, the connecting column 4 is embedded in the receiving part 3, that is, one end of the connecting column 4 and the clamping edge 41 are wrapped during the injection molding of the receiving part 3, so that the clamping edge 41 is embedded in the interior of the receiving part 3 to achieve the effect of integral molding of the connecting column 4 and the receiving part 3. In this way, the metal connecting column 4 can not only ensure the strength of the hanging object, but also ensure the firmness of the connection with the receiving part 3 by injection molding with the receiving part 3.

[0052] In another preferred case, a reinforcing column 34 is provided on one side of the receiving part 3 close to the base surface, and a through hole is provided on the reinforcing column 34 to form a connecting hole 35. The inner diameter of the connecting hole 35 is interference fit with the outer diameter of the connecting column 4, so that the connecting column 4 passes through the connecting hole 35, and the clamping edge 41 abuts against the edge of the connecting hole 35. Furthermore, a guide slope is provided on the end edge of the connecting hole 35, so that when the connecting column 4 passes through the connecting hole 35, the guide slope can form an avoidance groove for the clamping edge 41, and at the same time, the clamping edge 41 can be clamped on the guide slope to stabilize the connecting column 4.

[0053] In a preferred case, a first ridge 71 and a second ridge 72 are provided on the side wall of the receiving member 3, a limiting groove 7 is formed between the second ridge 72 and the first ridge 71, and the side edge of the first ridge 71 is flush with or protrudes from the top surface of the receiving member 3; it also includes a connector 8, the connector 8 is fixedly connected to the hanging object, and a plug-in groove 81 is provided on the connector 8, and the plug-in groove 81 is an inverted U-shaped structure with an opening at the bottom. The plug-in groove 81 is plugged and fixed on the first ridge 71 from top to bottom. At this time, the edge 82 of the plug-in groove 81 is clamped in the limiting groove 7, and the connector 8 is fixed to the receiving member 3, and the hanging object is hung. Combined with the way in which the connecting column can be inserted into the socket so that the connecting column and the socket can be separated, the socket 3 can have three connection methods with the hanging object, that is, the connecting column or the limiting groove is connected to the hanging object alone, or the connecting column and the limiting groove are connected to different hanging objects at the same time, further increasing the scope of application of the socket.

[0054] In a preferred case, an extension 61 is provided on the lower side of the receiving part 3, and a support 63 is provided on the side of the extension 61 close to the base surface. When the receiving part 3 is fixed, the support 63 is supported on the base surface so that the receiving part 3 is in a vertical state or tilted upward. In this way, it can form a two-point support and stability effect for the hanging object in cooperation with the suction cup 1, effectively reducing the problem of shaking of the hanging object when hanging, reducing the impact on the adsorption force of the suction cup 1, and indirectly improving the bearing capacity of the suction cup 1. Further, the extension 61 is bent toward the side close to the base surface to form the support 63. In another preferred case, the connecting column 4 is arranged on the extension 61.

[0055] In a preferred case, the receiving part 3 is further provided with a protective cover 6, which includes an annular wall 62, which surrounds the suction cup 1 and is connected to the receiving part 3, forming an effect that the protective cover 6 covers the suction cup 1, so that after the suction cup 1 is adsorbed and fixed on the base surface, the annular wall 63 surrounds the suction cup 1 to form a protective shell of the suction cup 1, so as to prevent the suction cup from being deformed by external force collision, which causes the vacuum chamber to enter air and lose its adsorption function. Preferably, the annular wall 62 is integrally formed with the receiving part 3.

[0056] In a preferred case, the connecting portion 2 includes a rectangular protrusion 21, and a clamping edge 22 extends to both sides from the top of the rectangular protrusion 21, and a slope is provided along the top edge of the clamping edge 222; a clamping groove 31 is provided on the receiving member 3, and an opening 32 is provided on the clamping groove 31, and the opening 32 has a tendency to gradually narrow toward the side away from the suction cup 1, and support surfaces 33 are provided on both sides of the narrowest end of the opening 32, and the rectangular protrusion 21 can be gradually inserted into the interior of the opening, that is, the narrow end of the opening 32 from the large end of the opening, and the two clamping edges 22 are squeezed with the inner wall of the opening 32, thereby causing the two clamping edges 22 and / or the side walls of the opening 32 to produce elastic deformation, thereby causing the two clamping edges 22 to pass through the narrowest end of the opening 32, and then the two clamping edges 22 and / or the opening 32 restore the elastic deformation, and the two clamping edges 22 are clamped on the two support surfaces 33. Since the narrowest end of the opening 32 is smaller than the size of the two clamping edges 22, the narrowest end of the opening 32 and the two supporting surfaces 33 and the two clamping edges 22 form a mutual limit, the two clamping edges 22 will not fall off from the narrow end of the opening 32, and the receiving member 3 will not fall off from the connecting portion 2, and the connection reliability is high. Only by putting the large end of the opening 32 of the receiving member 3 on the rectangular protrusion 21 and then applying pressure in the protruding direction to the receiving member 3, the receiving member 3 and the suction cup 1 are reliably connected, and the operation is simple and quick.

[0057] In a preferred embodiment, a through hole 23 is provided transversely along the center of the rectangular protrusion 21, and the extension direction of the through hole 23 is parallel to the clamping edge 22. At the same time, a blind hole 24 is provided longitudinally along the center of the rectangular protrusion. The through hole 23 and the blind hole 24 cooperate with the slope so that when the two clamping edges 22 and the opening 32 are squeezed against each other, the clamping edge 22 is more flexible and more prone to elastic deformation, and the clamping edge 22 is more likely to move closer to the center of the rectangular protrusion 21, so that the receiving part 3 can be connected to the connecting part 2 more labor-saving and conveniently. In a preferred embodiment, the opening 32 passes through the receiving part 3 along the axial direction of the receiving part 3, so that when the opening 32 and the two clamping edges 22 are squeezed against each other, the opening 32 is more flexible and more prone to elastic deformation toward the outside of the opening. Furthermore, the support surface 33 is lower than the top surface of the receiving member 3, and when the two clamping edges 22 are clamped on the two support surfaces 33, the top of the connecting portion 2 does not exceed the top surface of the receiving member 3, so as to prevent the connecting portion 2 from being too high and affecting the subsequent connection and fixation of the hanging object with the receiving member 3. At the same time, the distance between the hanging object and the base surface can be shortened, further ensuring the stability of the state of the hanging object when it is suspended.

[0058] In a preferred case, the suction cup 1 includes a disc body 11, a frame and a disc cover 12. The disc body 11 is covered on the frame, and a connecting portion 2 is provided on the frame. The connecting portion 2 and the frame 14 are integrally formed. A positioning hole 13 is provided at the center of the disc cover 12. The disc cover 12 is sleeved on the connecting portion 2 through the positioning hole 13 and covers the back of the disc body 11. A rectangular protrusion 21 is provided on the connecting portion 2. With the disc body 11 covered on the frame, the frame can support and shape the disc body 11 thereon, and can evenly transfer the pressure received to the disc body 11 to discharge the air in the disc body, and at the same time press the disc body 11 tightly against the base surface. In addition, there are multiple protrusions in a ring array on the frame, and the protrusions pass through the back of the disc body. In this way, when external force presses the connection part or the disc cover 12, the disc cover 12 compresses the disc body 11, the frame and the protrusions of the annular array. The protrusions apply a circumferential pressure to the disc body, so that the air in the inner edge of the disc body is further discharged and completely drained to form a vacuum cavity, so that the disc body 11 fits more closely with the base surface, is not easy to fall off the base surface, and has a stronger load-bearing capacity.

[0059] In the above technical solution, after the suction cup is pressed and fixed in a suitable position, the large end of the opening of the receiving part is sleeved on the rectangular protrusion, and a pressure vertical to the suction cup is applied to the receiving part, so that the rectangular protrusion is inserted into the receiving part, and the two clamping edges are squeezed with the inner wall of the opening, so that the two clamping edges and / or the opening are elastically deformed, and then the two clamping edges pass through the narrowest end of the opening, and then the two clamping edges and / or the opening restore the elastic deformation, and the two clamping edges are clamped on the two supporting surfaces, thereby realizing a reliable connection between the receiving part and the disk body. The operation is simple and quick, and a reliable connection between the receiving part and the suction cup is realized. The suction cup can be stably adsorbed on the base surface, so that the connecting column passes through the hanging object. At this time, the connecting column hangs the hanging object, and the object can be hung by screwing the fastener on the connecting column. The overall operation is simple and convenient.

[0060] This embodiment is only an illustration of the concept and implementation of the utility model, and does not limit it. Under the concept of the utility model, technical solutions that have not been substantially changed are still within the scope of protection.
