[0036] Specifically, the gel body 200 can be connected to one side of the back plate 100 for adsorption in a close manner, which can be bonding or through secondary injection molding, so that the back plate 100 and the gel body 200 can be made into a suction cup by the above connection, which is simple in structure and does not need to be assembled with complex accessories, and the other side of the back plate 100 is provided with a connecting part 130, which can be used to place articles or connect hooks, supporting rods and other accessories to expand the use of the suction cup, and the hard back plate 100 can provide support for the soft gel body 200 and improve the load-bearing performance of the suction cup, the back plate 100 can provide a certain pressure covering force to the gel body 200 after being pressed, thereby improving the adsorption performance of the suction cup, and the side of the back plate 100 and the gel body 200 can be provided with a protruding protruding part 110, the specific shape of the protruding part 110 is not limited here, and the protruding part 110 can be provided with multiple protruding parts 110, and the protruding part 110 can be arranged more densely without affecting the deformation of the back plate 100, and each protruding part 110 can be arranged near the outer edge of the back plate 100, so as to strengthen the pressure covering of the edge of the suction cup and block the gas from entering the negative pressure cavity from the outer edge, and the protruding part 110 can be more firmly connected with the gel body 200.

[0037] Referring to Figures 1 to 3 In some embodiments of the present application, the outer end of the protruding part 110 extends to the outer edge of the back plate 100. Specifically, after the protruding part 110 extends to the outer edge, the pressure covering force of the edge on the gel body 200 can be further improved, the range of pressure covering can be expanded, and the adsorption durability of the suction cup can be further improved.

[0038] It is conceivable that the protruding part 110 can also extend beyond the outer edge of the back plate 100, so that the protruding part 110 can extend to the outer edge of the protruding gel body 200, and after adsorption, the protruding part 110 can also protect the gel body 200 to block the impact of external force on the side of the gel body 200, causing the gel body 200 to be lifted and leak.

[0039] Referring to Figure 7 and Figure 8 In some embodiments of the present application, the gel body 200 has a vacuum area 210 in the middle, the vacuum area 210 is provided with an adsorption area 220 in the circumferential direction, the adsorption area 220 has a contact surface, and the projection of the protruding part 110 towards the contact surface is located inside the contact surface.

[0040] With reference to Figure 1 In some embodiments of the present application, the distance between adjacent protruding portions 110 is D, and D = 1mm-10mm. Specifically, the density of the protruding portions 110 affects the deformation of the back plate 100 and the pressing force on the gel 200. When the distance is too small or too large, the pressing force on the gel 200 is small after the back plate 100 is pressed. Through experiments, when D = 1mm-10mm, the back plate 100 can be easily deformed and the pressing force can be sufficient.

[0041] In some embodiments of the present application, the protruding thickness of the protruding portions 110 is uniform. Specifically, the protruding portions 110 can be arranged as uniform square strips. After pressing, the gel 200 is stressed uniformly, and the back plate 100 can be easily injection molded, which is convenient for production.

[0042] It is conceivable that the protruding portions 110 can also be trapezoidal, oval or irregular in shape, and the specific shape is not limited.

[0043] With reference to Figure 2 In some embodiments of the present application, the protruding portions 110 have a first inclined surface 111 on the outer side of the middle portion and a second inclined surface 112 on the inner side. The first inclined surface 111 is inclined toward the back plate 100 in the direction from inside to outside, and the second inclined surface 112 is inclined toward the back plate 100 in the direction from outside to inside. Specifically, the first inclined surface 111 on the outer side of the protruding portion 110 can extend to the outer edge of the back plate 100. The shape of the protruding portion 110 is defined by the first inclined surface 111 and the second inclined surface 112. The maximum height of the protruding portion 110 can be increased without affecting the deformation of the back plate 100, thereby further increasing the pressing force on the gel 200 and further improving the adsorption effect of the suction cup.

[0044] It is conceivable that before adsorption, the first inclined surface 111 can be substantially parallel to the surface to be adsorbed, thereby increasing the area of the pressing force.

[0045] It should be noted that the shape of the protruding portion 110 is not limited to the above embodiments, but can also have other embodiments. For example, the protruding portion 110 can also be arranged in multiple directions along the radial direction of the back plate 100, and can be spaced apart from inside to outside, and the height of each protruding portion 110 can also increase from inside to outside.

[0046] With reference to Figure 5In some embodiments of the utility model, the maximum height of the protruding part 110 protruding relative to the back plate 100 is H, H = 1mm-4mm, and the width of the protruding part 110 is B, B = 0.5mm-3mm. Specifically, if the protruding height of the protruding part 110 is too high, it will affect the extrusion exhaust, and if it is too small, it cannot play the role of strengthening the pressure coverage. After testing, when the maximum height H of the protruding part 110 is set to 1mm-4mm, it can not only facilitate the extrusion exhaust of the suction cup, but also can strengthen the edge pressure coverage of the colloid 200. And the width B of the protruding part 110 is set to 0.5mm-3mm, and the pressure coverage effect is better.

[0047] Referring to Figure 3 In some embodiments of the utility model, the width of the protruding part 110 gradually increases from inside to outside. Specifically, the back plate 100 can be injection molded, and the two sides of the protruding part 110 can be inclined, which can be inclined from inside to outside, so that the width of the protruding part 110 can be gradually expanded. On the one hand, the protruding part 110 can gradually expand outward to improve the pressure coverage of the outer edge, and the deformation of the back plate 100 is not affected. On the other hand, this structure can facilitate the glue running of the protruding part 110, and the injection molding is better.

[0048] Referring to Figure 5 In some embodiments of the utility model, the protruding part 110 is projected along the adsorption direction, and the extension length of the projection along the outside to the inside direction is L, L = 1mm-12mm. Specifically, the setting range of the protruding part 110 will affect the deformation of the back plate 100 and the pressure coverage of the colloid 200. After testing, within the range of L = 1mm-12mm, the back plate 100 can be deformed, and the colloid 200 can be provided with a certain pressure coverage.

[0049] Referring to Figures 1 to 3 In some embodiments of the utility model, the setting interval of the protruding part 110 is equal. Specifically, the uniformly arranged protruding part 110 can make the back plate 100 deform uniformly when pressed, and the colloid 200 can be uniformly stressed, and the adsorption effect is good.

[0050] In some embodiments of the utility model, backboard 100 can have porosity, the projection area of porosity along adsorption direction is set as K, the projection area of colloid 200 along adsorption direction is set as J, K:J < 0.1. Specifically, the porosity can be set on backboard 100, the deformation ability of backboard 100 can be improved, and the required pressing force is reduced, but backboard 100 can prevent air from penetrating into the adsorbed negative pressure area from colloid 200, when the porosity is set on backboard 100, air can penetrate from the porosity, through test, when the vacuum degree of suction cup is-60kPa, the ratio of K:J is respectively 0%, 2%, 4%, 6%, 8%, 12%, 16%, the time required for the vacuum degree of suction cup to drop 10kPa is respectively 78 days, 73 days, 64 days, 45 days, 31 days, 24 days, 22 days, therefore, when K:J < 0.2, the adsorption time of suction cup piece can meet the use demand.

[0051] In some embodiments of the utility model, K=0. Specifically, it can be understood that when K=0, the surface of backboard 100 and colloid 200 close combination is not provided with porosity, at this time, backboard 100 can completely cover and block the outside surface of colloid 200, the effect of preventing gas penetration is good, and then the adsorption durability of suction cup can be improved.

[0052] In some embodiments of the utility model, backboard 100 is made of plastic material, and colloid 200 is made of elastic material. Specifically, backboard 100 can be made of plastic material, such as PP, PC, PET and the like, which can have certain hardness, also has certain elasticity, and also can be injection molded, which is convenient for manufacturing, and colloid 200 can be made of soft and elastic materials such as silica gel and rubber, which has good adsorption effect.

[0053] It should be noted that when colloid 200 is injection molded on backboard 100, pressure is applied to the surface of backboard 100 and colloid 200 close combination, so that backboard 100 forms a shrinkage area.

[0054] Reference Figure 9 In some embodiments of the utility model, the surface of backboard 100 and colloid 200 close combination is provided with a plurality of grooves 140 and a plurality of convex columns 150, when the grooves 140 are set, each groove 140 is arranged around the middle part of backboard 100 at intervals, and the grooves 140 are arranged from inside to outside.
