[0002] With the improvement of living standards, people's living environment has been greatly improved. In modern families, every detail is exquisite. However, in order to make better use of living space or decorate space, sometimes you need to hang objects on the wall or furniture, but you don't want to put ugly nails or glue on the wall or furniture. In this case, you need to use a suction cup that is safe, stable and has long-lasting adsorption.

[0003] Suction cups are widely used in people's lives and production. They usually include a bowl-shaped main body. When used, the main body of the suction cup is usually squeezed to make the inner wall of the main body close to the base surface such as the wall, desktop, etc., and the air in the adsorption groove is discharged to generate a vacuum negative pressure to adsorb and fix the suction cup on the base surface. In order to improve the fixing effect of the suction cup, suction cups with a skeleton are widely used. The suction cup main body of this suction cup is made of a skeleton coated with rubber, a rectangular protrusion is provided on the back side of the skeleton, and an outer cover is provided outside the suction cup main body. A rectangular groove that is engaged with the rectangular protrusion is provided on the outer cover. The connection between the suction cup main body and the outer cover is achieved by engaging the rectangular protrusion in the rectangular groove. The outer cover includes a hanging part, which is connected to an external hanging part. The external hanging parts include hooks, racks, mop buckets and other items, so that the external hanging parts can be suspended and fixed. When in use, press the outer cover with your hand, and the outer cover presses the rubber-coated suction cup main body, presses out the air in the suction cup main body to form a vacuum cavity, and then fixes the suction cup on the base surface. The existing connection method of the rectangular protrusion and the rectangular groove is provided with a clamping edge at the end of the rectangular protrusion near the rectangular groove, and the rectangular groove includes two supporting bases, the two supporting bases are arranged opposite to each other, and the two supporting bases are directly connected to the outer cover, and a first connecting plate and a second connecting plate are connected in the middle of the two supporting bases, the first connecting plate and the second connecting plate are not directly connected to the outer cover, and the first connecting plate and the second connecting plate are arranged opposite to each other on both sides of the two bases and form a rectangular groove with the two supporting bases, and limiting protrusions are respectively provided on the first connecting plate and the second connecting plate, the clamping edge and the limiting protrusion are squeezed to cause the clamping edge and / or the limiting protrusion to produce elastic deformation, and then the clamping edge passes through the narrowest end of the limiting protrusion, and then the clamping edge and / or the limiting protrusion restore the elastic deformation, and at this time the connection between the suction cup body and the outer cover is completed. In this connection method, the first connecting plate and the second connecting plate are fixed only by two supporting bases. When the clamping edge and the limiting protrusion are squeezed, an outward thrust is generated on the first connecting plate and the second connecting plate. Under long-term use or when the thrust is large, the first connecting plate and the second connecting plate are easily damaged, which is not conducive to long-term use by users.

DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figures 1 to 6As shown, the suction cup includes a suction cup body 10 and a receiving portion 20, and a connecting portion 11 passing through the suction cup body 10 is provided on the back of the suction cup body 10, the connecting portion 11 includes a rectangular protrusion 12, and the receiving portion 20 includes a covering portion 21 and a hanging portion 23, the covering portion 21 and the hanging portion 23 are integrally formed, the covering portion 21 covers the outer periphery of the suction cup body 10, and the hanging portion 23 is connected to an external hanging part, and the external hanging part is any one of a mop bucket, a storage rack or a hook, and the hanging portion 23 includes a first limiting surface 231 for preventing the external hanging part from moving forward and backward, a second limiting surface 232 for preventing the external hanging part from moving left and right, and a third limiting surface 233 for preventing the external hanging part from falling off downward, and the first limiting surface 231, the second limiting surface 232, the third limiting surface 233 and the hanging portion 23 are integrally formed, so that the hanging portion 23 is less likely to be damaged. A snap-on edge 121 extends outward from one end of the rectangular protrusion 12 away from the suction cup body 10, and a rectangular groove 22 is provided on the side of the cover portion 21 close to the suction cup body 10, and a supporting edge 225 is provided in the rectangular groove 22. When the rectangular protrusion 12 is located in the rectangular groove 22, the suction cup body 10 and the receiving portion 20 are snap-fitted and connected through the snap-on edge 121 and the supporting edge 225. Two snap-on edges 121 are provided, and the two snap-on edges 121 are respectively provided on the long sides of the rectangular protrusion 12, and two supporting edges 225 are correspondingly provided, and the two supporting edges 225 are respectively provided on the long sides of the rectangular groove 22, so that the connection between the rectangular protrusion 12 and the rectangular groove 22 is tighter. The rectangular groove 22 includes a front plate 221, a left plate 222, a rear plate 223 and a right plate 224, wherein the front plate 221, the left plate 222, the rear plate 223 and the right plate 224 are all connected to the cover part 21, and the clamping edge 121 is respectively located on the left plate 222 and the right plate 224, and the front plate 221, the left plate 222, the rear plate 223 and the right plate 224 are connected end to end to form a rectangular groove 22, and realize the connection relationship between the rectangular groove 22 and the cover part 21. The left plate 222 and the right plate 224 are directly connected to the cover part 21. When the rectangular protrusion 12 is inserted into the rectangular groove 22 and elastic deformation occurs between the clamping edge 121 and / or the supporting edge 225, the pulling force on the left plate 222 and the right plate 224 is increased, so that the connection between the rectangular groove 22 and the cover part 21 is stronger, thereby making the connection between the suction cup body 10 and the receiving part 20 stronger, and the receiving part 20 is less likely to be damaged.

[0029] A first slope 122 is provided along the top edge of the clamping edge 121, and the first slope 122 is arranged on the side of the clamping edge 121 away from the suction cup body 10 and narrows toward the side away from the suction cup body 10. A second slope 226 is provided along the supporting edge 225, and the second slope 226 is arranged on the side of the supporting edge 225 close to the rectangular protrusion and narrows toward the side close to the rectangular protrusion. When the rectangular protrusion 12 is inserted into the rectangular groove 22, the first slope 122 and the second slope 226 transition from clearance fit to interference fit until the clamping edge 121 is clamped with the supporting edge 225. At this time, the distance between the supporting edge 225 and the cover part 21 is not less than the length of the first slope 122. At the same time, the first slope 122 and the second slope 226 are equivalent to reinforcing ribs, so that the supporting edge 225 and the clamping edge 121 are not easily damaged.

[0030] In a preferred embodiment, a through hole 123 is provided transversely along the rectangular protrusion 12, and the extension direction of the through hole 123 is parallel to the clamping edge 121. At the same time, a blind hole 124 is provided longitudinally along the center of the rectangular protrusion 12. The through hole 123 and the blind hole 124 cooperate with the first slope 122, so that when the two clamping edges 121 and the second slope 226 are squeezed against each other, the clamping edge 121 is more flexible and easier to elastically deform, and the clamping edge 121 is easier to move closer to the center of the rectangular protrusion 12, so that the receiving portion 20 can be connected to the suction cup body 10 more labor-saving and conveniently.

[0031] In a preferred embodiment, the suction cup body 10 includes a bowl-shaped frame (not shown in the figure), and a coating layer (not shown in the figure) is coated on the bowl-shaped frame. The frame can support and shape the coating layer. The coating layer protrudes from the cover part 21. When the disc body is pressed against the base surface, all the air in the disc body can be discharged. A connecting part 11 is provided on the back side of the frame, and the connecting part 11 is integrally formed with the frame. In a preferred embodiment, the suction cup also includes a disc cover 30. The disc cover 30 is bowl-shaped, and an annular convex rib (not shown in the figure) is provided at one end of the disc cover 30 close to the suction cup body 10. A positioning hole is provided in the center of the disc cover 30. The positioning hole cooperates with the rectangular protrusion. The disc cover 30 is sleeved on the connecting part 11 through the positioning hole and covers the back of the suction cup body 10. In this way, when an external force squeezes the connection part 11 or the disc cover 30, the disc cover 30 compresses the suction cup body through the annular convex rib, so that the annular convex rib generates a circumferential compressive force on the suction cup body and squeezes the suction cup body at the same time, so that the suction cup body is evenly stressed, and the suction cup body fits more closely with the base surface and is not easy to fall off the base surface. A plurality of strip through holes 31 in an annular array are also provided on the disc cover 30. The strip through holes 31 are located on the inner side of the annular convex rib. When an external force squeezes the disc cover 30, the disc cover 30 is slightly deformed. The length direction of the strip through holes 31 is the same as the radius direction of the disc cover 30, and a flexible deformation space is provided when the disc cover 30 is squeezed and deformed, thereby reducing the risk of the disc cover 30 breaking.

[0032] In a preferred embodiment, the cover part 21 includes a circular plate 211 connected to the rectangular groove 22 and an annular connector 212 surrounding the outer periphery of the circular plate 211. The circular plate 211 and the annular connector 212 are integrally formed. The annular connector 212 is connected to the hanging part 23. An outer cover 213 is provided on the side of the annular connector 212 away from the suction cup. A pressing mark 214 is provided on the side of the outer cover 213 away from the circular plate 211 to remind the user to press and use. A positioning groove 215 and a protrusion 216 are provided on the edge of the outer cover 213, and a positioning protrusion 217 and a groove 218 are provided on the inner side of the annular connector 212. During installation, first align the outer cover 213 with the annular connector 212, then rotate the outer cover 213 so that the positioning protrusion 217 is engaged in the positioning groove 215, and then press the outer cover 213 toward one side of the circular plate 211 so that the protrusion 216 is engaged in the groove 218, so that the outer cover 213 is embedded in the annular connector 212 and engaged with the annular connector 212.

[0033] In the above technical solution, the outer cover 213 is first snapped into the annular connector 212 to connect the outer cover 213 with the receiving portion 20, and then the disc cover 30 is covered on the back of the suction cup body 10, and the suction cup body with the disc cover 30 is pressed onto the base surface, and then the inner side of the receiving portion 20 is turned toward the connecting portion 11, and then the receiving portion 20 is pressed to make the first slope 122 and the second slope transition from a clearance fit to an interference fit, until the snap-in edge 121 and the supporting edge 225 are successfully snap-fitted.

[0034] 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.
