Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a suction cup that is easy to disassemble. Background Technology

[0002] Suction cups, as a common connecting and fixing device, are widely used in various occasions, such as material handling, glass installation, wall decoration, and home repair. Traditional suction cups usually rely on atmospheric pressure to form a tight bond with the object being attracted, thereby achieving the adsorption effect. They are characterized by simple structure, convenient fixing, and flexible relocation.

[0003] Most suction cups currently available are vacuum-adhesive structures. They consist of a bowl-shaped disc made of soft rubber or other flexible material, deeper in the center and shallower around the edges. The disc is pressed firmly against a substrate or object surface, and pressing down on the suction cup flattens and deforms the disc, expelling air between the disc and the substrate, thus adhering the disc to the surface. However, removing the suction cup usually requires considerable external force or a sharp, flat tool to forcibly lift the disc, making it time-consuming, laborious, and inconvenient. Furthermore, sharp, flat tools can easily scratch or damage the adhesive surface during removal, affecting its appearance and lifespan. Moreover, sharp, flat tools may also damage the suction cup itself, affecting its reusability. Utility Model Content

Detailed Implementation

[0046] This utility model provides a suction cup that is easy to disassemble, such as Figures 1-2 As shown, the suction cup includes a frame 1, on which an elastic colloid 101 is coated. The lower surface of the elastic colloid 101 forms an adsorption cavity that is deep in the middle and shallow around the edges. The suction cup also includes a cover assembly. The upper part of the frame 1 includes a connecting part, and the cover assembly is connected to the frame through the connecting part. The elastic colloid 101 has a first through hole 102 that penetrates the elastic colloid 101. The cover assembly includes a sealing part and a driving part, and the driving part is connected to a spring. In its natural state, the sealing part can seal the first through hole 102, ensuring a vacuum in the adsorption cavity when the suction cup is adsorbed onto the base surface, allowing the suction cup to be firmly adsorbed onto the base surface. When the driving part is pressed to compress the spring, it will move the sealing part, thereby releasing the seal on the first through hole 102, causing the elastic colloid 101 to release its adsorption onto the base surface, and thus allowing the suction cup to be disassembled.

[0047] When the suction cup is adsorbed onto the base surface, the sealing part blocks the first through hole 102, and the compression of the frame 1 causes the air in the adsorption chamber to be discharged and maintains the vacuum degree in the adsorption chamber, so the elastic colloid 101 is adsorbed onto the base surface. When the suction cup is released from adsorption, the spring is compressed by pressing the driving part, which drives the sealing part to move, thereby releasing the blockage of the first through hole 102, allowing outside air to enter the adsorption chamber of the elastic colloid 101 through the first through hole 102, releasing the vacuum degree in the adsorption chamber, and the elastic colloid 101 is released from adsorption, thus realizing the disassembly of the suction cup. With the setting of this device, when releasing and disassembling the suction cup, it is only necessary to press the driving part to move the sealing part, which saves time and effort, is convenient and quick, and is easy to operate. Compared with the prior art that uses external force or sharp flat tools to lift the suction cup, this device will not damage the suction cup or the adsorption base surface, will not affect the secondary use of the suction cup, will not affect the aesthetics of the adsorption base surface, and will ensure the service life of the suction cup.

[0048] The sealing part can be in the form of a cylindrical sealing rod 103, with one end of the sealing rod 103 blocking the first through hole 102, or it can be formed by combining and connecting multiple parts.

[0049] First Embodiment

[0050] like Figures 3-7As shown, in the first embodiment, the driving part is a pressure plate 2, the disk cover assembly includes a receiving cover 104, the frame 1 has a frame boss 105 in the middle, and the connecting part consists of two symmetrical first protrusions 106 and second protrusions 107 on the upper surface of the frame boss 105. The first protrusions 106 and second protrusions 107 are integrally formed with the frame 1, increasing the stability of the suction cup. The first protrusion 106 has a first protrusion engagement edge 108, and the second protrusion 107 has a second protrusion engagement edge 109. The outer edges of the upper surfaces of the first protrusion engagement edge 108 and the first protrusion engagement edge 109 are provided with guide ramps to facilitate engagement with the receiving cover 104. A receiving cover 104 covers the upper surface of the elastic colloid 101. A receiving cover protrusion 201 is provided on the inner side of the receiving cover 104. The lower part of the receiving cover protrusion 201 is provided with a first positioning hole 202, a second positioning hole 203, and a third positioning hole 204. The third positioning hole 204 is located between the first positioning hole 202 and the second positioning hole 203. The first positioning hole 202 corresponds to the first protruding plate 106, and the second positioning hole 203 corresponds to the second protruding plate 107, facilitating the connection between the frame 1 and the receiving cover 104. A first snap-fit ​​plate 205 is provided on the side wall of the first positioning hole 202 away from the third positioning hole 204, and a second snap-fit ​​plate 206 is provided on the side wall of the second positioning hole 203 away from the third positioning hole 204. The snap-fit ​​edge 108 of the first protruding plate can snap onto the first snap-fit ​​plate 205, and the snap-fit ​​edge 109 of the second protruding plate can snap onto the second snap-fit ​​plate 206. The top surfaces of the first snap-fit ​​plate 205 and the second snap-fit ​​plate 206 are provided with limiting edges. When the first protruding plate 106 is inserted into the first positioning hole 202 and the second protruding plate 107 is inserted into the second positioning hole 203, the deformation of the first protruding plate 106 and the second protruding plate 107 will respectively cause the first protruding plate snap-fit ​​edge 108 and the second protruding plate snap-fit ​​edge 109 to snap to the limiting edge. At this time, the first protruding plate 106 and the second protruding plate 107 restore their deformation so that the first protruding plate snap-fit ​​edge 108 and the second protruding plate snap-fit ​​edge 109 snap to and fix on the corresponding limiting edge, so that the receiving cover 104 snaps to and fixes on the first protruding plate 106 and the second protruding plate 107, so as to realize the connection between the receiving cover 104 and the skeleton 1, and facilitate the squeezing of the skeleton 1 to make the elastic colloid 101 adsorb onto the base surface.

[0051] The pressure plate 2 includes a pressing part 207. A first protrusion 208 is provided on the inner side of one end of the pressure plate 2 where the pressing part 207 is located. A sealing rod 103 is provided on the inner side of the end of the pressure plate 2 opposite to the pressing part 207. The sealing rod 103 can pass through the third positioning hole 204 and block the first through hole 102 to seal the elastic colloid 101, thereby facilitating the suction cup to be adsorbed onto the base surface. The outer side of the receiving cover 104 is provided with a first groove 209 and a second groove 210. The first positioning hole 202, the second positioning hole 203, and the third positioning hole 204 all communicate with the second groove 210. The pressure plate 2 is accommodated within the first groove 209 and the second groove 210 to provide space for the pressure plate 2 to move. A second protrusion 211 is provided on the bottom surface of the first groove 209. Mounting holes 212 are symmetrically provided on both side walls of the first groove 209. The second protrusion 211 is correspondingly positioned to the first protrusion 208. In this embodiment, the spring is a first spring 213, which is sleeved on the outer walls of the first protrusion 208 and the second protrusion 211. Preferably, the dimensions of the first protrusion 208 and the second protrusion 211 are the same to facilitate the sleeve of the first spring 213 on their outer walls. In its natural state, a gap exists between the first protrusion 208 and the second protrusion 211 to allow space for spring compression. That is, when the pressing part 207 of the pressure plate 2 is pressed, the first protrusion 208 moves, which in turn compresses the first spring 213. When the first protrusion 208 abuts against the second protrusion 211, it forms a limit, preventing further pressing. The pressure plate 2 has symmetrical support plates 214 on both sides. The ends of the support plates 214 are arc-shaped ends 215. In the natural state, the arc-shaped ends 215 abut against the bottom surface of the first groove 209 and the lower surface of the pressure plate 2 abuts against the bottom surface of the second groove 210. Each arc-shaped end 215 is provided with a mounting post 216, which can rotate within the mounting hole 212. The rotation of the mounting post 216 within the mounting hole 212 realizes the rotatable connection of the pressure plate 2 within the receiving cover 104.

[0052] In this embodiment, under natural conditions, the first spring 213 is unloaded, the pressure plate 2 is parallel to the outer wall of the receiving cover 104, and the bottom surface of the second groove 210 forms a limit so that the lower surface of the pressure plate 2 abuts against the bottom surface of the second groove 210. At this time, the sealing rod 103 on the pressure plate 2 can block the first through hole 102, and the squeezing frame 1 can make the suction cup adhere to the base surface. When the pressing part on the pressure plate 2 is pressed, the first protrusion 208 moves towards the inside of the suction cup. This causes the pressure plate 2 to rotate within the first groove 209 and the second groove 210 on the receiving cover 104, with the arc-shaped end 215 as the fulcrum. This causes one end of the pressure plate 2, where the pressing part 207 is located, to move towards the inside of the suction cup, while the other end of the pressure plate 2 moves towards the outside of the suction cup. In other words, the end of the pressure plate 2, where the sealing rod 103 is located, is lifted, which in turn lifts the sealing rod 103. The sealing rod 103 then releases the seal on the first through hole 102. At this time, air enters the elastic colloid 101, releasing the vacuum in the adsorption chamber of the elastic colloid 101, thereby releasing the suction cup from adsorption. At the same time, the first spring 213 is compressed. When the hand is released, the elastic force generated by the compression of the first spring 213 will push the first protrusion 208 to move outward of the suction cup, that is, the end of the pressing part 207 of the pressure plate 2 moves outward of the suction cup, causing the pressure plate 2 to rotate around the arc-shaped end 215 as the fulcrum. The end of the pressure plate 2 where the sealing rod 103 is located moves inward of the suction cup. Due to the limiting effect of the bottom surface of the second groove 210, the lower surface of the pressure plate 2 stops rotating when it abuts against the bottom surface of the second groove 210, so that the sealing rod 103 re-seals the first through hole 102, and the suction cup is reset.

[0053] In this embodiment, when using the suction cup, in its natural state, the pressure plate 2 is parallel to the outer wall of the receiving cover 104, and the sealing rod 103 on the pressure plate 2 will block the first through hole 102. The compression frame 1 ensures a vacuum in the adsorption cavity, and the elastic colloid 101 is adsorbed onto the base surface. When disassembling the suction cup, press the pressing part 207 on the pressure plate 2. The pressing part 207 on the pressure plate 2 moves inward to the suction cup, and the sealing rod 103 on the pressure plate 2 moves outward to the suction cup, so that the sealing rod 103 is lifted, thereby releasing the blockage of the first through hole 102. Outside air will enter the adsorption chamber of the elastic colloid 101 through the first through hole 102, releasing the vacuum in the adsorption chamber and releasing the suction cup. At this time, the first spring 213 is compressed. After releasing the pressing part 207 on the pressure plate 2, the elastic force generated by the compression of the first spring 213 will reset the pressure plate 2, and the sealing rod 103 will re-seal the first through hole 102. After the suction cup is reset, the suction cup can be disassembled and adsorbed on other base surfaces.

The way in which the first protruding plate 106 is snapped onto the first snap-fit ​​plate 205 and the second protruding plate 107 is snapped onto the second snap-fit ​​plate 206 is the same as in the first embodiment, and will not be described again here.

One end of the guide plate 303 is flush with the edge of the second through hole 301, and the other end of the guide plate 303 extends to the edge of the receiving cover boss 302. The movable plate 3 can slide between the two guide plates 303. By setting the guide plates 303, the movement of the movable plate 3 is guided. The receiving cover protrusion 302 is connected to a protective cover 304. The edge of the receiving cover protrusion 302 is provided with several locking interfaces 305. In this embodiment, there are two locking interfaces 305, which are symmetrically arranged on both sides of the receiving cover protrusion 302. The inner edge of the protective cover 304 is provided with two locking blocks 306 corresponding to the locking interfaces 305. The locking blocks 306 can be locked into the locking interfaces 305 to realize the locking of the protective cover 304 and the receiving cover 104.

[0057] One end of the protective cover 304 has a protective cover through hole 307, and one end of the movable plate 3 is a trigger part 308. The trigger part 308 extends through the protective cover through hole 307 to facilitate pressing the trigger part 308. The top surface of the movable plate 3 has a movable plate groove 309. The end of the movable plate groove 309 away from the trigger part 308 has a movable plate recess 310. The movable plate recess 310 is sealed by a sealing plate 311. The length of the sealing plate 311 is greater than the distance between the two guide plates 303 to limit the movement of the movable plate 3.

[0058] The spring components in this embodiment include a first spring 213 and a second spring 312. A first protrusion 313 is provided on the outer side of the sealing plate 311.

[0059] The movable plate recess 310 has a plurality of guide protrusions 315 symmetrically arranged at intervals on its two edges along the length direction. In this embodiment, there are two guide protrusions 315 on each edge. The side of the guide protrusion 315 away from the trigger part 308 has a raised ramp 316 to facilitate the movement of the guide protrusion 315, thereby causing the movable plate 3 to move. The movable plate 3 is connected to a support block 317, which passes through the movable plate recess 310. The upper part of the support block 317 has a support block protrusion 318, and the support block protrusion 318 has two guide recesses 319 corresponding to the guide protrusions 315. The shape of the guide recesses 319 matches that of the guide protrusions 315 so that the guide protrusions 315 are engaged in the guide recesses 319, thereby realizing the engagement of the movable plate 3 and the support block 317. When the trigger part 308 is pressed down, the movable plate 3 moves downward. Due to the raised ramp 316, the guide protrusion 315 on the movable plate 3 moves downward, which in turn causes the guide recess 319 to be lifted, thereby lifting the support block 317. There are two guide protrusions 315 and two guide recesses 319 on each edge, so that the guide protrusions 315 form four-point support when moving, making the movement of the movable plate 3 more stable. In the natural state, the first spring 213 is in an unloaded state. The side of the support block 317 away from the trigger part 308 abuts against the sealing plate 311, and the other side of the support block 317 leaves a gap with the side wall of the recess 310 of the movable plate, providing space for the movable plate 3 to move. In this embodiment, the sealing rod 103 is provided on the bottom surface of the support block 317, and the sealing rod 103 blocks the first through hole 102. The top surface of the support block 317 is provided with a support block groove 320, and the bottom surface of the support block groove 320 is provided with a second protrusion 321. In the natural state, the second spring 312 is compressed. One end of the compressed second spring 312 is sleeved on the outer side wall of the second protrusion 321, and the other end abuts against the inner side wall of the protective cover 304.

[0060] In this embodiment, under natural conditions, the second spring 312 is compressed between the support block 317 and the protective cover 304. The compression of the second spring 312 generates elastic force, which pushes the sealing rod 103 on the bottom surface of the support block 317 to block the first through hole 102. The compression of the frame 1 can make the suction cup adhere to the base surface. At this time, the first spring 213 is in an unforced state. When the trigger part 308 on the movable plate 3 is pressed, the movable plate 3 will move downward. The downward movement of the movable plate 3 will drive the sealing plate 311 to move downward. The movement of the sealing plate 311 will compress the first spring 213. When the sealing plate 311 abuts against both ends of the U-shaped limiting plate 314, it reaches the limit and stops moving. At this time, due to the movement of the guide protrusion 315 on the movable plate 3, the support block 317 will be lifted. The sealing rod 103 on the bottom surface of the support block 317 will be lifted accordingly. The sealing rod 103 will release the blockage of the first through hole 102, thereby releasing the suction cup. At the same time, the second spring 312 will be further compressed. When the press on the trigger part 308 on the movable plate 3 is released, the elastic force of the compressed first spring 213 will push the sealing plate 311 to move upward, thereby driving the movable plate 3 to move upward. When the sealing plate 311 abuts against both ends of the guide plate 303, it reaches the limit and stops moving. At this time, the first spring 213 resets, the movable plate 3 resets, and the elastic force generated when the second spring 312 is further compressed will push the support block 317 to fall, thereby driving the sealing rod 103 on the support block 317 to fall, so that the sealing rod 103 re-seals the first through hole 102, and the suction cup resets.

[0061] In this embodiment, when using the suction cup, the first spring 213 is in an unstressed state, the sealing plate 311 abuts against the ends of the two guide plates 303, and the second spring 312 is in a compressed state. The elastic force of the compressed second spring 312 causes the sealing rod 103 on the support block 317 to block the first through hole 102, compressing the skeleton 1 to maintain a vacuum in the adsorption chamber, and the elastic colloid 101 is then adsorbed onto the base surface. When disassembling the suction cup, pressing the trigger part 308 on the movable plate 3 causes the movable plate 3 to move. The movement of the movable plate 3 causes the support block 317 to be lifted, thereby releasing the sealing rod 103 from blocking the first through hole 102. Outside air enters the adsorption chamber of the elastic colloid 101 through the first through hole 102, releasing the vacuum in the adsorption chamber and thus releasing the suction cup. At the same time, the movement of the movable plate 3 will drive the sealing plate 311 to move, thereby compressing the first spring 213, and the second spring 312 will be further compressed. When the press on the trigger part 308 on the movable plate 3 is released, the elastic force of the first spring 213 being compressed causes the movable plate 3 to reset, and at the same time the elastic force of the second spring 312 being further compressed causes the support block 317 to reset, thereby causing the sealing rod 103 to re-seal the first through hole 102. After the suction cup is reset, the suction cup can be disassembled for adsorption on other base surfaces.

[0062] The easily detachable suction cup provided by this utility model has a bowl-shaped frame 1 that is higher in the middle and lower around the edges. An annular protrusion 110 and several strip-shaped protrusions 111 are provided on the outer edge of the frame 1. The strip-shaped protrusions 111 are evenly distributed circumferentially on the frame 1. The strip-shaped protrusions 111 can extend radially or be arc-shaped, curving in the same direction. The annular protrusion 110 penetrates and connects the strip-shaped protrusions 111, enhancing the strength of the frame 1 and strengthening the connection between the elastic colloid 101 and the frame 1, preventing the elastic colloid 101 from detaching from the frame 1. Several strip-shaped slots 112 are provided along the edge of the frame 1. The strip-shaped slots 112 can extend radially or be arc-shaped and curved in the same direction. The strip-shaped slots 112 are evenly distributed around the edge of the frame 1. Strip-shaped holes 113 are also provided on the frame 1. The strip-shaped holes 113 are located between the first protruding plate 106, the second protruding plate 107, and the annular protrusion 110. The strip-shaped holes 113 are evenly distributed around the frame 1. The strip-shaped holes 113 can extend radially or be arc-shaped and curved in the same direction. The arrangement of the strip-shaped slots 112 and strip-shaped holes 113 makes the deformation of the frame 1 more convenient and less labor-intensive.
