DETAILED DESCRIPTION

[0057] The utility model provides a suction cup which is convenient for releasing adsorption, such as Figures 1-2 As shown, it includes a frame 1, on which an elastic colloid 101 is coated, and 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 receiving assembly. The upper portion of the frame is provided with a connecting portion, and the receiving assembly is connected to the frame 1 via the connecting portion. The elastic colloid 101 is provided with a first through hole 102, which penetrates the elastic colloid 101. The receiving assembly includes a blocking member and a driving member. The blocking member can block the first through hole 102 through the driving member, so that when the suction cup is adsorbed on the base surface, the vacuum degree in the adsorption cavity can be guaranteed, so that the suction cup can be firmly adsorbed on the base surface.

[0058] The skeleton 1 is provided with a skeleton boss 103, and the skeleton boss 103 is provided with a boss through-hole 104 that passes through the skeleton 1. The elastic colloid 101 is provided with an elastic colloid boss 105, and the elastic colloid boss 105 abuts within the boss through-hole 104. The upper surface of the elastic colloid boss 105 is flush with the upper surface of the skeleton boss 103. In this embodiment, the boss through-hole 104 is a stepped through-hole. The boss through-hole 104 can also be of other shapes so that the elastic colloid 101 can more closely cover the skeleton 1. The upper surface of the skeleton boss 103 is provided with two symmetrically arranged raised plates 106, and the raised plates 106 are integrally formed with the skeleton 1. Each raised plate 106 is provided with a raised plate clamping edge 107. The receiving assembly also includes a receiving cover 2. A guide slope is provided on the outer edge of the upper surface of the raised plate clamping edge 107 to facilitate clamping with the receiving cover 2. The receiving cover 2 is covered on the upper surface of the elastic colloid 101. The receiving cover 2 is provided with a rectangular through hole 201. The edge of the rectangular through hole 201 is provided with a hollow rectangular protrusion 202 in communication with the rectangular through hole 201 towards the interior of the receiving cover 2. The inner wall of the rectangular protrusion 202 is symmetrically provided with a clamping plate 203. The position of the clamping plate 203 corresponds to the position of the clamping edge 107 of the protruding plate, and the clamping edge 107 of the protruding plate can be clamped on the clamping plate 203. The top surface of the clamping plate 203 is provided with a limiting edge. When the raised plate 106 is inserted into the rectangular through hole 201, the deformation of the raised plate 106 will cause the raised plate clamping edge 107 to be clamped to the limiting edge. At this time, the raised plate 106 restores its deformation so that the raised plate clamping edge 107 is clamped and fixed on the limiting edge, so that the receiving cover 2 is clamped and fixed on the raised plate 106, so as to realize the connection between the receiving cover 2 and the frame 1, and facilitate the receiving cover 2 to extrude the elastic colloid 101 to be adsorbed on the base surface.

[0059] The frame 1 of the suction cup provided by the present invention, which facilitates desorption, is bowl-shaped, with a high center and low edges. An annular protrusion 108 and a plurality of strip-shaped protrusions 109 are provided on the outer edge of the frame 1. The strip-shaped protrusions 109 are evenly distributed around the frame 1 and can extend radially or be curved in the same direction. The annular protrusions 108 extend through and connect the strip-shaped protrusions 109, thereby 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 falling off the frame 1. The edge of the frame 1 is provided with a plurality of strip slits 110. These slits 110 may extend radially or be arc-shaped, curving in the same direction. These slits 110 are evenly distributed around the edge of the frame 1. The frame 1 is also provided with strip holes 111, located between the raised plate 106 and the annular protrusion 108. These strip holes 111 are evenly distributed around the frame 1. These strip holes 111 may extend radially or be arc-shaped, curving in the same direction. The provision of these strip slits 110 and these strip holes 111 makes deformation of the frame 1 more convenient and labor-saving.

[0060] When the suction cup is adsorbed on the base surface, the blocking member blocks the first through hole 102, squeezing the skeleton 1 to expel the air in the adsorption chamber and ensure the vacuum in the adsorption chamber, and the elastic colloid 101 is then adsorbed on the base surface; when the suction cup is desorbed, the blocking member is moved by the driving unit, 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 in the adsorption chamber, and desorbing the elastic colloid 101. Through the configuration of this device, when desorbing the suction cup, it is only necessary to move the blocking member, which saves time and effort and is convenient and quick. Compared with the prior art method of using sharp flat blades or other tools to pry up the elastic colloid 101, this device will not damage the elastic colloid 101, will not affect the secondary use of the suction cup, and ensures the service life of the suction cup.

[0061] Furthermore, the blocking piece is fixedly connected to the driving part, and the driving part is movably connected to the receiving cover 2. The movable connection method is any method or any combination of rotational connection, sliding connection or rotational connection, and the blocking piece is driven to move at the position of the first through hole 102 by rotating, sliding or rotating the driving part on the receiving cover 2, thereby blocking or unblocking the first through hole 102.

[0062] The elastic colloid in the present invention further includes an edge portion 230, which surrounds the elastic colloid boss 105. The first through hole 102 can be located on the elastic colloid boss 105 or on the edge portion 230. In addition, the first through hole 102 can be located at the center of the elastic colloid boss 105 or at an eccentric position of the elastic colloid boss 105, as long as the blocking member corresponds to the position of the first through hole 102 and can block the first through hole.

[0063] Furthermore, the blocking member may be in the form of a cylindrical blocking rod 204 , with one end of the blocking rod 204 blocking the first through hole 102 , or may be a blocking member formed by combining and connecting multiple parts.

[0064] like Figures 3-6 As shown, in the first embodiment, the blocking member is a cylindrical blocking rod 204, and the first through hole 102 is provided at the center of the elastic colloid boss 105. A circular protrusion 206 is provided on the edge of the rectangular through hole 201 of the receiving cover 2, facing the outside of the receiving cover 2. The circular protrusion 206 is in communication with the rectangular through hole 201, and the outer wall of the circular protrusion 206 is provided with an external thread 207. In this embodiment, the suction cup also includes a threaded cover 208. The blocking rod 204 is fixed to the inner surface of the threaded cover 208. The blocking rod 204 and the threaded cover 208 are integrally formed. The inner side wall of the threaded cover 208 is provided with an internal thread 209 that cooperates with the external thread 207. Through the cooperation of the external thread 207 and the internal thread 209, the threaded cover 208 is threadedly connected to the circular protrusion 206, thereby achieving the connection between the threaded cover 208 and the receiving cover 2.

[0065] In this embodiment, when using the suction cup, the threaded cover 208 is screwed tightly onto the circular protrusion 206 so that the sealing rod 204 in the threaded cover 208 blocks the first through hole 102, and the skeleton 1 is squeezed to ensure the vacuum degree in the adsorption chamber, and the elastic colloid 101 is adsorbed on the base surface; when the suction cup is desorbed, the threaded cover 208 is loosened, and the threaded cover 208 moves outward relative to the receiving cover 2. The outward movement of the threaded cover 208 will cause the sealing rod 204 to move outward accordingly, thereby releasing the blockage of the first through hole 102, and the outside air will enter the adsorption chamber of the elastic colloid 101 through the first through hole 102, releasing the vacuum degree in the adsorption chamber, and releasing the adsorption of the suction cup.

[0066] like Figures 7-11 As shown, in the second embodiment, the blocking member is a cylindrical blocking rod 204, and the first through hole 102 is provided at the center of the elastic colloid boss 105. The edges of the rectangular through hole 201 of the receiving cover 2 are provided with two symmetrically arranged support plates 210 facing the outside of the receiving cover 2. The support plates 210 are provided with support plate clamping edges 211, and the support plates 210 are integrally formed with the receiving cover 2. The suction cup in this embodiment also includes a sliding member 212, which includes two symmetrically arranged side plates 213. The upper edge of each side plate 213 is slidably clamped in the support plate clamping edge 211, thereby realizing the sliding of the sliding member 212 relative to the receiving cover 2. The length of the side plate 213 is greater than the length of the support plate 210, creating a sliding space for the sliding of the sliding member 212. The upper surface of the side plate 213 is parallel to the outer surface of the receiving cover 2, and the lower surface of the side plate 213 is inclined relative to the outer surface of the receiving cover 2. The inclined lower ends of the two side panels 213 are fixedly connected to a first sealing plate 214, and the inclined upper ends of the two side panels 213 are fixedly connected to a second sealing plate 215. The first sealing plate 214, the second sealing plate 215, and the two side panels 213 are integrally formed. The length of the first sealing plate 214 or the second sealing plate 215 is greater than the distance between the two side panels 213, and the four sides of the first sealing plate 214 or the second sealing plate 215 protrude from the two side panels 213, thereby limiting the sliding length of the sliding member 212. The lower surface of each side panel 213 is provided with a wing panel 216, which is arranged toward the middle of the two side panels 213 and is arranged at an angle and parallel to the lower surface of the side panels 213, so that the wing panel 216 and the side panels 213 have the same inclination direction and inclination angle.

[0067] The suction cup in this embodiment also includes a hollow fixing member 217, which includes two oppositely arranged fixing member grooves 218. The fixing member grooves 218 correspond to the raised plate 106, and the raised plate 106 is clamped in the fixing member grooves 218, thereby limiting the fixing member 217. The upper surface of the fixing member 217 protrudes from the outer surface of the receiving cover 2 and is arranged parallel to the wing plate 216. The blocking rod 204 is fixed to the inside of the fixing member 217 and is integrally formed with the fixing member 217. The top of the fixing member 217 is provided with a fixing member boss 219, and the fixing member boss 219 is provided with a fixing member flange 220 on both sides. The upper surface of the fixing member flange 220 is parallel to the outer surface of the receiving cover 2, and the lower surface of the fixing member flange 220 is inclined and parallel to the upper surface of the fixing member 217 to form an inclined groove 221. The inclined groove 221 has the same inclination angle and inclination direction as the wing plate 216. The wing plate 216 is slidably engaged in the inclined groove 221, thereby enabling the sliding member 212 to slide relative to the fixing member 217. Through this arrangement, the side plate 213 of the sliding member 212 can slide horizontally relative to the receiving cover 2, and the wing plate 216 of the sliding member 212 can tilt and slide relative to the receiving cover 2. In this embodiment, when the first sealing plate 214 abuts the two support plates 210, the sliding contact position of the sliding member 212 and the fixing member 217 is located at the inclined lower end of the wing plate 216, and the blocking rod 204 in the fixing member 217 can block the first through hole 102. When the sliding member 212 is pushed to move the second sealing plate 215 closer to the two support plates 210, the side plate 213 of the sliding member 212 slides horizontally relative to the receiving cover 2, and the wing plate 216 of the sliding member 212 slides relative to the receiving cover 2, and the sliding contact position of the sliding member 212 and the fixing member 217 moves toward the inclined high end of the wing plate 216. However, the receiving cover 2 is fixed, and the sliding member 212 will lift the fixing member 217 that is slidably connected to the wing plate 216 of the sliding member 212, thereby allowing the blocking rod 204 to release the blockage of the first through hole 102.

[0068] In this embodiment, when the suction cup is adsorbed on the base surface, the first sealing plate 214 of the sliding member 212 is abutted against the two support plates 210, and the blocking rod 204 in the fixing member 217 will block the first through hole 102, squeezing the skeleton 1 to ensure the vacuum degree in the adsorption chamber, and the elastic colloid 101 will be adsorbed on the base surface; when the suction cup is desorbed, the sliding member 212 is pushed to make the second sealing plate 215 of the sliding member 212 move toward the two support plates 210. Since the wing plate 216 on the sliding member 212 slides obliquely relative to the receiving cover 2, the sliding member 212 will lift the fixing member 217, causing the blocking rod 204 in the fixing member 217 to be lifted accordingly, thereby releasing the blockage of the first through hole 102, and the outside air will enter the adsorption chamber of the elastic colloid 101 through the first through hole 102, releasing the vacuum degree in the adsorption chamber, and releasing the adsorption of the suction cup.

[0069] like Figure 12 As shown, in the third embodiment, the blocking member is a cylindrical blocking rod 204, and the first through hole 102 is located at an eccentrically upward position of the elastic colloid boss 105. The blocking rod 204 in the fixing member 217 corresponds to the position of the first through hole 102 to achieve blocking of the first through hole 102. The other components and usage methods of this embodiment are the same as those of the second embodiment and are not repeated here.

[0070] like Figures 13-16 As shown, in the fourth embodiment, the blocking member is a cylindrical blocking rod 204, and the first through hole 102 is located at the center of the elastic colloid boss 105. Two support plates 222 are provided along the edge of the rectangular through hole 201 of the receiving cover 2, facing the outside of the receiving cover 2. The two support plates 222 are symmetrically arranged, and the ends of the two support plates 222 on the same side are provided with mounting holes 223. The suction cup in this embodiment also includes a flip plate 224, and the blocking rod 204 is fixed to the inner surface of the flip plate 224. One end of the flip plate 224 is provided with symmetrical mounting bosses 225 facing the inner surface. Each mounting boss 225 is provided with a mounting protrusion 226. The mounting protrusion 226 matches the mounting hole 223 and can rotate within the mounting hole 223, thereby realizing the rotation of the flip plate 224 relative to the support plate 222. A pressure plate 227 is provided at the other end of the flip plate 224, facing the inner surface. The pressure plate 227 provides support for the lower portion of the flip plate 224 and limits the downward rotation of the flip plate 224. Through this arrangement, when the flip plate 224 is parallel to the outer surface of the receiving cover 2, the blocking rod 204 blocks the first through hole 102, and the suction cup can achieve adsorption to the base surface. When the flip plate 224 is pulled and rotated, the rotation of the flip plate 224 drives the blocking rod 204 inside the flip plate 224 to move, causing the blocking rod 204 to release its blockage of the first through hole 102, thereby releasing the adsorption of the elastic colloid 101 to the base surface. Moreover, since the elastic colloid 101 is made of elastic material and has a certain degree of elasticity, the first through hole 102 also has a certain degree of elasticity, which prevents the blocking rod 204 from interfering with the first through hole 102 when the flip plate 224 rotates, further ensuring the movement of the blocking rod 204 and ensuring that the blocking rod 204 unblocks the first through hole 102.

[0071] In this embodiment, when using the suction cup, the flip plate 224 is flipped to be level with the outer surface of the receiving cover 2, and the blocking rod 204 in the flip plate 224 will block the first through hole 102, squeezing the skeleton 1 to ensure the vacuum in the adsorption chamber, and the elastic colloid 101 will be adsorbed on the base surface, and then the suction cup will be adsorbed on the base surface; when the suction cup is desorbed, the flip plate 224 is lifted and rotated, and the blocking rod 204 will move with the rotation of the flip plate 224, thereby releasing the blockage of the first through hole 102, and the 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 adsorption of the suction cup.

[0072] like Figure 17 As shown, in the fifth embodiment, the blocking member is a cylindrical blocking rod 204, the first through hole 102 is located at an eccentric downward position of the elastic colloid boss 105, and the blocking rod 204 in the flip plate 224 corresponds to the position of the first through hole 102 to achieve blocking of the first through hole 102. The other components and usage methods of this embodiment are the same as those of the fourth embodiment and are not repeated here.

[0073] like Figures 18-19 As shown, in the sixth embodiment, the blocking member is a cylindrical blocking rod 204, and the first through hole 102 is provided on the edge portion 230 of the elastic colloid 101, the skeleton 1 is provided with a second through hole 231 corresponding to the first through hole 102, and the first through hole 102 is located inside the second through hole 231, the elastic colloid 101 is provided with a first through hole boss 232, the first through hole 102 is provided on the first through hole boss 232, and the first through hole boss 232 is provided. The arrangement increases the edge thickness of the first through hole 102 while ensuring the sealing effect; a receiving cover groove 233 is provided at one end of the receiving cover 2 close to the first through hole 102, and a pull plate 234 is rotatably connected in the receiving cover groove 233. A third through hole 235 corresponding to the first through hole 102 is provided on the receiving cover 2, and the blocking rod 204 is provided on the side of the pull plate 234 facing the skeleton 1. The blocking rod 204 can pass through the third through hole 235 and then block the first through hole 102.

[0074] In this embodiment, when using the suction cup, the pull plate 234 is rotated and fitted into the receiving cover groove 233, so that the blocking rod 204 in the pull plate 234 abuts against the first through hole boss 232 and blocks the first through hole 102, and the skeleton 1 is squeezed to ensure the vacuum degree in the adsorption chamber, and the elastic colloid 101 is adsorbed on the base surface, and then the suction cup is adsorbed on the base surface; when the suction cup is desorbed, the pull plate 234 is lifted and rotated away from the receiving cover groove 233, and the blocking rod 204 will move with the rotation of the pull plate 234, thereby releasing the blockage of the first through hole 102, and the outside air will enter the adsorption chamber of the elastic colloid 101 through the first through hole 102, releasing the vacuum degree in the adsorption chamber, and then releasing the adsorption of the suction cup.

[0075] Furthermore, the cross-sectional shape of the blocking rod 204 in the present invention can be any shape, as long as it ensures that the blocking rod 204 blocks the first through-hole. In a preferred embodiment, the cross-sectional shape of the blocking rod 204 is circular, and the blocking rod 204 includes a blocking rod arcuate end 205. The diameter of the blocking rod arcuate end 205 is larger than the diameter of the first through-hole 102, ensuring the sealing performance of the blocking rod arcuate end 205 in blocking the first through-hole 102. In addition, due to the elasticity of the elastic colloid 101, the blocking rod arcuate end 205 can more smoothly block or be removed from the first through-hole 102, thereby ensuring that the blocking rod 204 can smoothly block or release the first through-hole 102.

[0076] like Figure 20 As shown, in the seventh embodiment, the sealing member is a cylindrical sealing rod 204, the first through hole 102 is located in an eccentric downward position of the elastic colloid boss 105, the sealing rod 204 in the flip plate 224 corresponds to the position of the first through hole 102, the cross-sectional shape of the sealing rod 204 is square and can block the first through hole 102, and the other components and usage methods in this embodiment are the same as those in the fourth embodiment and will not be repeated here.

[0077] like Figure 21 As shown, in the eighth embodiment, the blocking member includes a cylindrical blocking rod 204, one end of which is connected to a blocking piece 236 for blocking the first through hole 102. The other end of the blocking rod is connected to the flip plate 224. When the flip plate 224 rotates, it drives the blocking piece 236 on the blocking rod 204 to move, thereby releasing the blockage of the first through hole 102. The shape of the blocking piece 236 is not limited and can be any shape such as circular, square, or polygonal, as long as it can block the first through hole 102. The other components and usage methods of this embodiment are the same as those of the fourth embodiment and will not be repeated here.

[0078] Furthermore, the blocking member may be integrally formed with the corresponding connecting member, as described in the first to eighth embodiments above. In addition, the blocking member may also be detachably connected to the corresponding connecting member.

[0079] like Figure 22 As shown, in the ninth embodiment, the blocking member includes a connected blocking piece 236 and a blocking rod 204. A flip plate boss 237 is provided inside the flip plate 224, and a boss groove 238 is provided on the flip plate boss 237. The blocking rod 204 is movably connected to the boss groove 238. In this embodiment, the blocking rod 204 is inserted into the boss groove 238 to achieve the connection between the blocking member and the flip plate 224. The blocking piece 236 is coated with an elastic film 239, which can block the first through hole. When the suction cup is adsorbed on the base surface, the elastic film 239 blocks the first through hole. When the flip plate rotates, it drives the blocking rod 204 in the boss groove 238 to move, which in turn drives the elastic film 239 to move, thereby releasing the blockage of the first through hole and releasing the suction cup. The other components and usage methods of this embodiment are the same as those of the fourth embodiment and will not be repeated here.

[0080] The receiving cover 2 provided by the present invention, which facilitates the release of the suction cup, is also provided with a hanging portion for connecting to external objects. The hanging portion can be any of a hook, a slot, or a screw. In this embodiment, a lower extension 228 is provided on the outer wall of the receiving cover 2. The end of the lower extension 228 is provided with a slot 229 for connecting to external objects, which facilitates the connection or hooking of external objects.
