Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, specifically to a detachable suction cup cover. Background Technology

[0002] To better utilize or decorate living space, it is sometimes necessary to hang items on walls or furniture, but without wanting to nail unsightly nails or glue them. In such cases, suction cups that are safe, stable, and have long-lasting adhesion are needed.

[0003] To improve the fixation effect of suction cups, suction cups with frames are widely used. The suction cup body of this type of suction cup is made by coating the frame with rubber. A rectangular protrusion is provided on the back side of the frame, and a receiving cover is provided on the outside of the suction cup body. The receiving cover has a rectangular groove that engages with the rectangular protrusion. The connection between the suction cup body and the receiving cover is achieved by engaging the rectangular protrusion into the rectangular groove. The receiving cover includes a disc cover and a receiving element. A hook is provided at the bottom of the receiving element for connecting to the object being hung. The disc cover and the receiving element are integrally molded, and the disc cover has a rectangular groove. During use, pressing the disc cover by hand compresses the rubber-coated suction cup body, forcing out the air inside the suction cup body to form a vacuum chamber, thereby fixing the suction cup to the base surface. Existing support covers feature a single-piece molding process where the cover and support component are integrally formed. This simplifies manufacturing and allows for production of the entire support cover in a single mold (i.e., one-mold production). However, this type of support cover has poor adaptability. When different types or specifications of objects need to be suspended, due to the specific nature of the support component, a new mold is often required to create a new support cover to meet the new suspension requirements. Although the structure of the cover itself remains unchanged, the fact that the cover and support component are designed as a single unit means that each replacement of the support component requires redesigning and remolding the entire support cover, undoubtedly increasing mold-making costs. Furthermore, when either the cover or the support component is damaged, the entire support cover needs to be replaced, resulting in material waste. Utility Model Content

[0004] The purpose of this invention is to provide a detachable suction cup cover, in which the receiving part and the cover are set separately, which can adapt to different hanging objects. This type of suction cup cover does not require the entire suction cup cover to be re-molded during manufacturing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] Preferably, the annular protrusion is rectangular and gradually narrows towards the side away from the suction cup body. Support surfaces are provided on both sides of the narrowest end of the annular protrusion. The rectangular protrusion is inserted from the large end of the annular protrusion into the narrow end of the annular protrusion, and the two locking edges are locked onto the two support surfaces through the narrowest end of the annular protrusion.

[0014] Preferably, the annular protrusion extends through the disc cover along the axial direction of the disc cover.

[0015] Preferably, when the two locking edges are engaged on the two support surfaces, the top of the rectangular protrusion does not exceed the side of the annular protrusion away from the suction cup body.

[0016] Preferably, the suspension part includes a first limiting surface to prevent the external hanging part from moving back and forth, a second limiting surface to prevent the external hanging part from moving left and right, and a third limiting surface to prevent the external hanging part from falling downwards. The first limiting surface, the second limiting surface, the third limiting surface and the receiving part are integrally formed.

[0017] Preferably, the suspension part includes a connecting post and a fastener. The connecting post protrudes from the surface of the receiving member, and the surface of the connecting post is provided with external threads. The fastener is screwed and fixed to the connecting post.

[0018] Preferably, one end of the connecting post is provided with a retaining edge, the outer diameter of which is larger than the outer diameter of the connecting post; the connecting post passes through the receiving member and the retaining edge abuts against the receiving member; the fastener is a mushroom cap with internal threads, and a hexagonal nut is provided at the opening of the mushroom cap.

[0019] Preferably, the receiving component has a reinforcing post on the side near the base surface, and the reinforcing post has a connecting hole, the inner diameter of which matches the outer diameter of the connecting post; the retaining edge is embedded inside the connecting hole.

[0020] Preferably, the suspension part includes a limiting hole, and the limiting hole is connected to a snap-fit ​​block through a connecting plate. The snap-fit ​​block protrudes completely from the limiting hole and has a gap between it and the top surfaces on both sides of the limiting hole.

[0021] Preferably, the connecting plate is longitudinally positioned in the middle of the limiting hole, dividing the limiting hole into a first limiting hole and a second limiting hole.

[0022] Preferably, a reinforcing rib is provided on the side of the connecting plate away from the snap-fit ​​block.

[0023] Preferably, there are two limiting holes, and the two limiting holes are arranged symmetrically; the connecting plate and the snap-fit ​​block are also provided in two forms, each corresponding to one of the two limiting holes.

[0024] Preferably, the suction cup body includes a skeleton and a gel covering the skeleton, the connecting part is disposed on the skeleton and protrudes from the gel, and the connecting part is integrally formed with the skeleton.

[0025] Preferably, the disc cover includes a circular base plate connected to the snap-fit ​​portion, and a mounting groove is formed between the circular base plate and the side of the annular wall away from the suction cup body. An outer cover is embedded in the mounting groove. The circular base plate is provided with an insertion hole, and the outer cover is provided with a protrusion on the side near the circular base plate. The protrusion is inserted into the insertion hole.

[0026] In the above technical solution, by separating the suction cup cover and the receiving component, the appropriate receiving component can be selected for installation as needed, eliminating the need to replace the suction cup cover and increasing its versatility and adaptability. Because the structure of the suction cup cover is universal, it can be reused in various scenarios. Only corresponding molds for the receiving components need to be designed for different receiving components, avoiding repeated mold openings due to changes in the overall structure, saving material consumption and shortening the production cycle. Furthermore, if either the suction cup cover or the receiving component is damaged, only the damaged part needs to be replaced. The receiving component has a mounting hole at its top, and the suction cup cover has a hollow annular protrusion at its center. The receiving component is connected to the suction cup cover by fitting the mounting hole around the annular protrusion. The inner wall of the mounting hole abuts against the upper and lower surfaces of the annular protrusion, limiting the vertical movement of the mounting hole and thus securing the suction cup cover to the receiving component. Furthermore, the disc cover includes a circular base plate and an annular wall circumferentially arranged along the edge of the circular base plate. A notch is provided at the bottom of the annular wall, through which the side wall of the receiving component passes. The two sides of the notch extend upwards to form protruding ridges, which abut against the side walls of the receiving component, thus limiting the left-right position of the receiving component and preventing it from moving relative to the disc cover. This completes the fixation of the receiving component's left-right and up-down positions by the disc cover. Even further, by setting the depth of the mounting hole to be the same as the height of the annular protrusion, when the connecting part is inserted into the annular protrusion, the connecting part and the annular protrusion limit the mounting hole in the front-back direction, preventing the receiving component from moving in that direction. At this time, the suction cup and the disc cover simultaneously limit the receiving component's front-back, left-right, and up-down positions, ensuring the receiving component is securely connected between them without any shaking.

[0027] By incorporating a suspension unit at the bottom of the mounting bracket, the object is hung and fixed to the bracket, thus securing it to the base surface. The object can be any of the following: hooks, mop buckets, trash cans, or shelves, offering a wide range of applications. A support platform is also located at the bottom of the mounting bracket near the base surface. This platform supports the bracket vertically or at an upward angle, providing two-point support and stability for the object when used with the suction cup. This effectively reduces swaying during hanging, minimizes the impact on the suction cup's adhesion, and indirectly increases the suction cup's load-bearing capacity. Attached Figure Description

[0043] The present invention will be further described below with reference to the accompanying drawings:

[0044] like Figures 1 to 14 As shown, a detachable suction cup cover includes a suction cup body 1, a cover 2, and a receiving component 3. The receiving component 3 has a mounting hole 35 at its top and a hanging part 31 at its bottom. A connecting part 13 protruding from the suction cup body 1 is provided on the back side of the suction cup body 1. A snap-fit ​​part 24 is provided on the cover 2, including a hollow annular protrusion 241 extending from the center of the cover 2 towards the suction cup body 1. The mounting hole 35 is fitted around the annular protrusion 241, and the connection between the three components is achieved by inserting the connecting part 13 into the annular protrusion 241. By separating the cover 2 and the receiving component 3, a suitable receiving component 3 can be selected for installation on the desired hanging object (not shown in the attached figure) without requiring a complete re-molding of the cover 2 and the receiving component 3, significantly reducing production costs. The hanging object can be any of hooks, mop buckets, trash cans, or shelves, offering a wide range of applications. If either the cover 2 or the receiving part 3 is damaged, only the damaged part needs to be replaced, thus saving on usage costs.

[0045] The mounting hole 35 is fitted around the annular protrusion 241, and the inner wall of the mounting hole 35 abuts against the upper and lower surfaces of the annular protrusion 241. This limits the vertical movement of the mounting hole 35 by the outer wall of the annular protrusion 241, thereby fixing the receiving part 3 vertically in place by the disc cover 2. Further, the disc cover 2 includes a circular base plate 21 and an annular wall 23 circumferentially arranged along the edge of the circular base plate 21. A notch 231 is provided at the bottom of the annular wall 23, through which the side wall of the receiving part 3 passes. The two sides of the notch 231 extend upward to form protruding ridges 232, which abut against the two side walls of the receiving part 3, and also abut against the left and right sides of the receiving part 3. The position is limited to prevent the receiving part 3 from moving in the left and right directions relative to the disc cover 2. At this time, the disc cover 2 fixes the receiving part 3 in the left and right and up and down directions. Furthermore, by setting the depth of the mounting hole 35 to be the same as the height of the annular protrusion 241, when the connecting part 13 is inserted into the annular protrusion 241, the connecting part 13 and the annular protrusion 241 limit the mounting hole 35 in the front and back directions to prevent the receiving part 3 from moving in the front and back directions. At this time, the suction cup body 1 and the disc cover 2 simultaneously limit and fix the receiving part 3 in the front and back, left and right and up and down directions. That is, the receiving part 3 is firmly connected between the two and will not shake.

[0046] In this embodiment, by providing a suspension part 31 at the bottom of the receiving part 3, the object is hung and fixed on the receiving part 3, thus fixing the object to the base surface. A support platform 34 is also provided at the bottom of the receiving part 3 near the base surface. The support platform 34 supports the receiving part 3, making it vertical or tilted upwards. This, in conjunction with the suction cup body 1, provides two-point support and stability for the object, effectively reducing the swaying of the object during suspension, reducing the impact on the suction force of the suction cup body 1, and indirectly improving the load-bearing capacity of the suction cup body 1.

[0047] In a preferred embodiment, the connecting portion 13 includes a rectangular protrusion 131, with locking edges 132 extending from the top of the rectangular protrusion 131 to both sides, and a ramp 133 provided along the top edge of the locking edges 132; the annular protrusion 241 is rectangular and gradually narrows towards the side away from the suction cup body 1, with support surfaces 242 provided on both sides of the narrowest end of the annular protrusion 241, the rectangular protrusion 131 is inserted into the narrow end of the annular protrusion 241 from the large end of the annular protrusion 241, the two locking edges 132 are squeezed against the inner wall of the annular protrusion 241, thereby causing elastic deformation of the two locking edges 132 and / or the side wall of the annular protrusion 241, thereby allowing the two locking edges 132 to pass through the narrowest end of the annular protrusion 241, and then the two locking edges 132 and / or the annular protrusion 241 recover their elastic deformation, and the two locking edges 132 are engaged on the two support surfaces 242. Because the narrowest end of the annular protrusion 241 is smaller than the dimensions of the two locking edges 132, the narrowest end of the annular protrusion 241 and the two supporting surfaces 242 mutually limit each other with respect to the two locking edges 132. The two locking edges 132 will not detach from the narrow end of the annular protrusion 241, and the disc cover 2 will not detach from the connecting part 13, resulting in high connection reliability. Simply placing the large end of the hollow annular protrusion 241 onto the rectangular protrusion 131 and applying vertical pressure to the disc cover 2 achieves a reliable connection between the disc cover 2 and the suction cup body 1, making the operation simple and quick.

[0048] In this embodiment, a through hole 134 is provided laterally along the center of the rectangular protrusion 131, and the extension direction of the through hole 134 is parallel to the snap-fit ​​edge 132. Simultaneously, a blind hole 135 is provided longitudinally along the center of the rectangular protrusion 131. The through hole 134, the blind hole 135, and the ramp 133, together with the slope, make the snap-fit ​​edge 132 more flexible and easier to elastically deform when the two snap-fit ​​edges 132 and the annular protrusion 241 are pressed against each other. The snap-fit ​​edge 132 is also more likely to move towards the center of the rectangular protrusion 131, thus allowing the disc cover 2 to be connected to the connecting part 13 more easily and effortlessly. In this embodiment, the annular protrusion 241 penetrates the disc cover 2 along its axial direction, making it more flexible and easier to elastically deform towards the outside of the annular protrusion 241 when the annular protrusion 241 and the two snap-fit ​​edges 132 are pressed against each other. Furthermore, the support surface 242 is lower than the top surface of the annular protrusion 241, and when the two snap-fit ​​edges 132 are snapped onto the two support surfaces 242, the top of the rectangular protrusion 131 does not exceed the side of the annular protrusion 241 away from the suction cup body 1, preventing the connecting part 13 from being too high and affecting the subsequent connection and fixation between the hanging object and the receiving part 3. At the same time, it can shorten the distance between the hanging object and the wall, further ensuring the stability of the hanging object when suspended.

[0049] In a preferred embodiment, the suspension part 31 includes a first limiting surface 311 to prevent the external hanging part from moving back and forth, a second limiting surface 312 to prevent the external hanging part from moving left and right, and a third limiting surface 313 to prevent the external hanging part from falling downward. The first limiting surface 311, the second limiting surface 312, the third limiting surface 313 and the suspension part 31 are integrally formed, making the suspension part 31 less prone to damage.

[0050] In a preferred embodiment, the suspension part 31 includes a connecting post 323 and a fastener 325. The connecting post 323 is a metal rod with a retaining edge 324 at one end. After the connecting post 323 passes through the receiving part 3, the retaining edge 324 abuts against the inner wall of the receiving part 3. The outer diameter of the retaining edge 324 is larger than the outer diameter of the connecting post 323, enhancing the connection between the connecting post 323 and the receiving part 3 and preventing the connecting post 323 from falling off. The surface of the connecting post 323 is provided with external threads, and the fastener 325 is screwed onto the external threads. After the connecting post 323 passes through the object to be hung, the fastener 325 is screwed onto the connecting post 323, thus the object to be hung can be fixedly suspended by the suction cup body 1. The overall structure is simple and easy to use. Furthermore, the fastener 325 is a mushroom cap 326 with internal threads. The smooth arc-shaped mushroom cap 326 can cover and wrap the end of the connecting post to prevent the end of the connecting post from scratching the support. A hexagonal nut 327 is provided at the opening of the mushroom cap 326. The hexagonal nut 327 can easily screw the fastener 325 onto the connecting post.

[0051] In this embodiment, the connecting post is embedded in the receiving member 3. That is, when the receiving member 3 is injection molded, one end of the connecting post 323 and the retaining edge 324 are wrapped around it, so that the retaining edge 324 is embedded in the interior of the receiving member 3, achieving the effect of the connecting post 323 and the receiving member 3 being integrally formed. In this way, the metal connecting post 323 can ensure the strength of the suspended object, and the injection molding with the receiving member 3 can also ensure the firmness of the connection between them. The receiving component 3 has a reinforcing post 321 on the side near the base surface. The reinforcing post 321 has a connecting hole 322. The inner diameter of the connecting hole 322 is interference-fitted with the outer diameter of the connecting post, so that the connecting post 323 passes through the connecting hole 322 and the retaining edge 324 abuts against the edge of the connecting hole 322. Furthermore, a guide ramp 133 is provided at the end edge of the connecting hole 322. When the connecting post 323 passes through the connecting hole 322, the guide ramp 133 can form a relief groove for the retaining edge 324. At the same time, the retaining edge 324 can be locked on the guide ramp 133 to stabilize the connecting post 323.

[0052] In a preferred embodiment, the suspension part 31 includes a limiting hole, and a connecting plate 333 is provided at the middle position of the limiting hole along the length direction of the receiving part 3. The connecting plate 333 is integrally formed with the receiving part 3. The connecting plate 333 divides the limiting hole into a first limiting hole 331 and a second limiting hole 332. A snap-fit ​​block 334 is fixedly connected to the side of the connecting plate 333 away from the base surface. The snap-fit ​​block 334 protrudes completely from the limiting hole and has a gap between it and the top surfaces on both sides of the limiting hole. By snapping the snap-fit ​​block 334 into the groove on the top of the hanging object, the hanging object is connected to the base surface through the suction cup body 1. Without human operation, the snap-fit ​​block 334 will not come out of the groove, so that the hanging object is firmly connected and will not fall off. Furthermore, a reinforcing rib 335 is provided on the side of the connecting plate 333 away from the snap-fit ​​block 334. The reinforcing ribs 335 are arranged in a crisscross pattern, and a longitudinal reinforcing rib 335 is provided in the middle of the connecting plate 333. This reduces the weight of the receiving component 3 while increasing the connection between the snap-fit ​​block 334 and the receiving component 3, so that even if the weight of the hanging object is large, it will not cause damage or even detachment of the snap-fit ​​block 334.

[0053] In a preferred embodiment, two through holes 134 are provided, and the two through holes 134 are arranged laterally on both sides of the bottom of the receiving member 3 with the receiving member 3 as the axis of symmetry. This can prevent the receiving member 3 from rotating due to unbalanced force on the hanging object, thus affecting the connection effect of the suction cup body 1. The connecting plate 333 and the snap-fit ​​block 334 are also provided in twos, each corresponding to the two mounting holes. Increasing the number of suspension components can increase the number of hanging objects, making it more convenient to use.

[0054] In a preferred embodiment, the suction cup body 1 includes a frame 11 and a gel 12 covering the periphery of the frame 11. A connecting part 13 is disposed on the frame 11 and integrally formed with the frame 11, and the connecting part 13 protrudes from the gel 12. By covering the frame 11 with the gel 12, the frame 11 can support and shape the gel 12 on it, and can evenly transmit the pressure to the gel 12 to expel the air in the gel 12, while pressing the gel 12 tightly against the base surface.

[0055] In this application, the disc cover 2 includes a circular base plate 21 connected to the snap-fit ​​part 24. A mounting groove 22 is formed between the circular base plate 21 and the side of the annular wall 23 away from the suction cup body 1. An outer cover 4 is embedded in the mounting groove 22. An insertion hole 221 is provided on the dome base plate 21. A protrusion 41 is provided on the side of the outer cover 4 near the circular base plate 21. The protrusion 41 is inserted into the insertion hole 221 to realize the connection between the outer cover 4 and the mounting groove 22, making the disc cover 2 in this application more aesthetically pleasing.

[0056] In the above technical solution, after the suction cup body 1 is fixed in a suitable position, the mounting hole 35 on the upper part of the receiving part 3 is fitted around the annular protrusion 241, and the two ends of the receiving part 3 abut against the two protruding ridges 232 respectively. At this time, the receiving part 3 is limited in the left and right and up and down directions. Then, the large end of the hollow annular protrusion 241 of the disc cover 2 is fitted onto the rectangular protrusion 131, and pressure perpendicular to the suction cup body 1 is applied to the disc cover 2. At this time, the rectangular protrusion 131 is inserted into the hollow annular protrusion 241, and the two locking edges 132 are squeezed against the inner wall of the annular protrusion 241, thereby causing the two locking edges 132 and / or the annular protrusion 241 to be squeezed together. The 241 generates elastic deformation, causing the two locking edges 132 to pass through the narrowest end of the annular protrusion 241. Subsequently, the two locking edges 132 and / or the annular protrusion 241 recover their elastic deformation, and the two locking edges 132 are locked onto the two support surfaces 242. This achieves a reliable connection between the disc cover 2 and the suction cup body 1, while also limiting the front and rear directions of the receiving part 3. The operation is simple and quick. The suction cup body 1 can be stably adsorbed onto the base surface. Different receiving parts 3 can be selected according to different hanging objects, and the hanging objects can be connected to the suspension part 31. At this time, the suspension part 31 suspends the hanging objects. The overall operation is simple and convenient.

[0057] This embodiment is merely an illustration of the concept and implementation of this utility model, and is not intended to limit it. Under the concept of this utility model, the technical solution without substantial changes is still within the protection scope.
