Description

Technical Field

[0001] The utility model relates to the field of suction cups, in particular to a suction cup pressure cup and a suction cup assembly. Background Art

[0002] A suction cup forms a vacuum cavity by pressing to expel the air inside, and uses the pressure difference between the inside and outside to fix household items on the base surface. It is usually adsorbed on walls, cabinets, etc. for hanging items. A type of suction cup commonly used now has a plate body made of a skeleton covered with rubber. The plate body is provided with a connecting part for connecting hooks, etc., which is generally a connecting column. The skeleton of the suction cup plays a role in supporting and shaping the rubber layer thereon. The skeleton can transmit force to expel the air in the rubber layer, and at the same time squeeze the rubber layer of the plate body tightly against the base surface. In existing suction cups, a pressure plate is usually set on the back of the plate body. The pressure plate is connected to the connecting column. The force on the pressure plate directly acts on the back of the plate body to make the plate body stick to the base surface.

[0003] A Chinese invention patent with publication number CN113819136A discloses an assembled suction cup assembly, which includes: a suction cup body, the front of the suction cup body is used to attach to the base surface to be installed, the middle part of the suction cup body is an inner concave part, the outer periphery of the inner concave part is a fitting part for attaching to the base surface on the front of the suction cup body, the back of the suction cup body is integrally provided with a raised connecting piece, the end of the connecting piece is provided with a first locking part; a pressure plate member, the pressure plate member is configured to The outer circumference of the inner recess of the suction cup body is less than covered, and the middle part of the pressure plate member is provided with a through hole for the connecting member to pass through; a locking member, and the locking member is provided with a second locking portion that cooperates with the first locking portion; wherein the back side of the suction cup body and at least one of the pressure plate member is provided with a raised spacer block arranged outside the inner recess area to separate the suction cup body from the pressure plate member, and the locking member biases the pressure plate member and the inner recess of the suction cup body toward each other when locked in place.

[0004] In the above scheme, when the pressure plate part cooperates with the suction cup body, the mating surfaces on both sides are relatively flat, and both the pressure plate part and the suction cup body are elastic. When the pressure plate part is subjected to force, it needs to undergo a certain degree of deformation before the force can be transmitted to the suction cup body. Therefore, the force acting on the pressure plate part needs to be relatively large, otherwise the adsorption effect of the suction cup will be relatively general and it will be easy to fall off. Summary of the Invention

[0005] In order to solve the above problems, the first purpose of the present invention is to provide a suction cup pressure plate, which increases the pressure on the suction cup body by arranging multiple annular pressure strips on the lower end surface of the pressure plate, improves the adsorption effect, and makes the suction cup closer to the base surface; the second purpose of the present invention is to provide a suction cup assembly having the above-mentioned suction cup pressure plate.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] A suction cup pressure plate comprises a plate body and a positioning boss arranged at the center of the upper end of the plate body; a through hole is constructed at the center of the positioning boss for the connection column on the frame to pass through; it is characterized in that: the lower end surface of the plate body of the pressure plate is provided with a plurality of downwardly protruding annular pressure strips, and the plurality of annular pressure strips are arranged in at least one circle along the outer edge of the lower end surface of the plate body in the circumferential direction, and the lower end surfaces of the annular pressure strips on the same circle are flush.

[0008] In the above technical solution, multiple annular beadings are provided on the lower end surface of the pressure plate. These beadings increase pressure on the suction cup body, enhancing the suction cup's adsorption efficiency. The multiple annular circumferential partitions are designed to reduce the impact of the beadings on the strength increase, making them relatively more susceptible to deformation. Furthermore, the provision of multiple annular beadings enhances the structural strength of the pressure plate and extends its service life.

[0009] Preferably, the multiple annular strips are arranged in multiple circles along the outer edge of the lower end surface of the disk body; the width of the annular strips in the inner circle is smaller than the width of the annular strips in the outer circle, and the lower end surface of the annular strips in the inner circle is higher than the lower end surface of the annular strips in the outer circle. In this technical solution, multiple annular strips are arranged in multiple circles. When the pressure plate squeezes the disk body, the disk body is squeezed first from the annular strips at the outer edge. The annular strips on the inner side have a small width, which is conducive to the deformation of the disk body of the pressure plate and is not easy to break. The lower end surface of the annular strips in the inner circle is higher than the lower end surface of the annular strips in the outer circle, so that the multiple circles of annular strips gradually squeeze the suction cup body from the outside to the inside, adapting to the deformation requirements of the disk body of the pressure plate.

[0010] Preferably, the annular bead is integrally formed with the disc body by injection molding. In this technical solution, the annular bead is integrally formed with the disc body by injection molding, which can greatly improve the structural strength of the pressure plate and extend the service life of the pressure plate.

[0011] Preferably, the disc body is an elastic disc-shaped pressure plate, which includes, radially from the inside to the outside, a central ring area arranged around the positioning boss, an annular deformation area around the outside of the central ring area, and an annular pressure area around the outside of the annular deformation area; the multiple annular pressure strips are arranged on the lower end surface of the annular pressure area. In this technical solution, the disc body of the pressure plate is an elastic disc-shaped pressure plate, and the disc body of the pressure plate is divided into a central ring area, an annular deformation area and an annular pressure area radially from the inside to the outside, which can meet the deformation requirements of the disc body when the suction cup is in use; specifically, after the central ring area is subjected to force, the force is transmitted to the annular pressure area through the deformation of the annular deformation area, and then the suction cup body is squeezed by the multiple annular pressure strips on the annular pressure area.

[0012] Preferably, the disk body is constructed with a plurality of deformation holes extending through the upper and lower end surfaces of the disk body, at least within the annular deformation zone. The holes are spaced circumferentially, and the inner and outer ends of the holes extend at least radially across the annular deformation zone. In this technical solution, when the central annular zone is subjected to force, the force is transmitted to the annular pressure zone through the deformation of the annular deformation zone. The provision of deformation holes in at least the annular deformation zone enhances the deformation capacity of the annular deformation zone, making it easier to deform and reducing the effort required to squeeze the annular deformation zone.

[0013] Preferably, the inner ends of the deformation holes are located on the central annular area, while the outer ends extend into the annular pressure area. The annular beading and the deformation holes are arranged alternately around the circumference. In this technical solution, the deformation holes extend from the central annular area to the annular pressure area, enhancing the overall deformation capacity of the pressure plate, making it easier to deform and reducing the effort required to squeeze the pressure plate.

[0014] Preferably, the deformable holes are constructed as strip-shaped holes extending only in the radial direction, with the outer ends of the strip-shaped holes pointing between two adjacent annular strips. In this technical solution, the deformable holes are constructed as strip-shaped holes extending only in the radial direction, so that the arrangement direction of the deformable holes is consistent with the direction of force transmission, thereby making the deformable holes easier to deform and improving the deformation capacity of the pressure plate body.

[0015] Preferably, the central ring area is in the shape of a curved surface that gradually rises from the inside to the outside. In this technical solution, the central ring area is in the shape of a curved surface that gradually rises from the inside to the outside, which is conducive to transferring the force at the center to the outer edge, is easy to deform, and has good stability.

[0016] Preferably, the annular deformation zone is in the shape of an arcuate surface that bends from the inside to the outside and below, or in the shape of an inclined surface that tilts from the inside to the outside and below; the thickness of the annular pressure zone is greater than the thickness of the central annular zone and the annular deformation zone. In this technical solution, the annular deformation zone is configured to be in the shape of an arcuate surface that bends from the inside to the outside and below, or in the shape of an inclined surface that tilts from the inside to the outside and below, which can facilitate the annular deformation zone to transfer the force at the upper end to the lower end; and the thickness of the annular pressure zone is greater than the thickness of the central annular zone and the annular deformation zone, which can improve the structural strength of the annular pressure zone, so that when the annular pressure strip acts on the suction cup body, the annular pressure zone remains stable, and at the same time, a transition is formed between the annular pressure zone and the annular deformation zone, which has a certain effect of improving the deformation effect.

[0017] A suction cup assembly includes a suction cup body and a pressure cup, wherein the suction cup body includes a pressing frame and an elastic colloid covering the pressing frame; the lower end surface of the elastic colloid is constructed into an arched adsorption cavity with the center higher than the edge of the cup body; the characteristic is that it also includes a pressure cup for pressing the suction cup described in any one of the above, and the multiple annular pressure strips on the pressure cup are pressed against the edge of the upper end surface of the suction cup body. In this technical solution, the suction cup assembly includes a suction cup body and a pressure cup, and the pressure cup and the suction cup body are assembled by the cooperation of a connecting rod and a through hole. After assembly, the multiple annular pressure strips on the pressure cup are pressed against the edge of the upper end surface of the suction cup body. When in use, the user acts on the pressure cup, and the slight deformation of the pressure cup can cause the multiple annular pressure strips to quickly squeeze the suction cup body to expel the air in the arched adsorption cavity, thereby allowing the suction cup body to be adsorbed on the substrate, which is more labor-saving.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature. Example 1:

[0035] like Figures 1 to 4 As well as the two suction cup pressure plates shown in 7 to 10, comprising a plate body 1, and a positioning boss 2 arranged at the center of the upper end of the plate body 1; a through hole 4 for the connecting column 3 on the frame to pass through is constructed at the center of the positioning boss 2; the lower end surface of the plate body 1 of the pressure plate 100 is provided with a plurality of downwardly protruding annular moldings 5, and the plurality of annular moldings 5 are arranged in at least one circle circumferentially along the outer edge of the lower end surface of the plate body 1, and the lower end surfaces of the annular moldings 5 on the same circle are flush.

[0036] In the above technical solution, multiple annular beadings are provided on the lower end surface of the pressure plate. These beadings increase pressure on the suction cup body, enhancing the suction cup's adsorption efficiency. The multiple annular circumferential partitions are designed to reduce the impact of the beadings on the strength increase, making them relatively more susceptible to deformation. Furthermore, the provision of multiple annular beadings enhances the structural strength of the pressure plate and extends its service life.

[0037] Furthermore, the multiple annular beadings 5 are arranged in multiple circles along the outer edge of the lower end surface of the disc body 1 at intervals in the circumferential direction; the width of the annular beadings 5 in the inner circle is smaller than the width of the annular beadings 5 in the outer circle, and the lower end surface of the annular beadings 5 in the inner circle is higher than the lower end surface of the annular beadings 5 in the outer circle. In this technical solution, the multiple annular beadings are arranged in multiple circles. When the pressure plate squeezes the disc body, the disc body is squeezed first from the outer edge annular beading. The annular beadings on the inner side are narrow, which is conducive to the deformation of the disc body of the pressure plate and is not easy to break. The lower end surface of the annular beading in the inner circle is higher than the lower end surface of the annular beading in the outer circle. Therefore, the multiple circles of annular beadings gradually squeeze the suction cup body from the outside to the inside, adapting to the deformation requirements of the disc body of the pressure plate.

[0038] Furthermore, the annular bead 5 is integrally injection-molded with the disc body 1. In this technical solution, the annular bead 5 is integrally injection-molded with the disc body, which can greatly improve the structural strength of the pressure plate and extend its service life.

[0039] Furthermore, the disc body 1 is a disc-shaped pressure plate with elasticity, and the disc body 1 includes, radially from the inside to the outside, a central ring area 6 arranged around the positioning boss 2, an annular deformation area 7 around the outside of the central ring area 6, and an annular pressure area 8 around the outside of the annular deformation area 7; the multiple annular pressure strips 5 are arranged on the lower end surface of the annular pressure area 8. In this technical solution, the disc body of the pressure plate is a disc-shaped pressure plate with elasticity, and the disc body of the pressure plate is divided into a central ring area, an annular deformation area and an annular pressure area in radial order from the inside to the outside, which can meet the deformation requirements of the disc body when the suction cup is in use; specifically, after the central ring area is subjected to force, the force is transmitted to the annular pressure area through the deformation of the annular deformation area, and then the suction cup body is squeezed by the multiple annular pressure strips on the annular pressure area.

[0040] Furthermore, the disc body 1 is constructed with a plurality of deformation holes 9 extending through the upper and lower end surfaces of the disc body 1, at least within the annular deformation zone 7. The plurality of deformation holes 9 are arranged at intervals along the circumference, and the inner and outer ends of the deformation holes 9 at least radially span the annular deformation zone 7. In this technical solution, when the central annular zone is subjected to force, the force is transmitted to the annular pressure zone through the deformation of the annular deformation zone. By providing at least the deformation holes in the annular deformation zone, the deformation capacity of the annular deformation zone is enhanced, making it easier to deform and saving effort when squeezing the annular deformation zone.

[0041] It should be noted here that if Figures 1 to 4 As shown, the inner end of the deformation hole 9 is located on the central ring area 6, and the outer end extends into the annular pressure area 8; and the annular pressure strip 5 and the deformation hole 9 are arranged alternately in the circumferential direction, which improves the overall deformation ability of the pressure plate body, makes it easy to deform, and saves more effort when squeezing the pressure plate body.

[0042] Furthermore, the deformation holes 9 are constructed as strip holes extending only in the radial direction, with the outer ends of the strip holes pointing between two adjacent annular beadings 5. In this technical solution, the deformation holes are constructed as strip holes extending only in the radial direction, so that the arrangement direction of the deformation holes is consistent with the direction of the transmitted force, thereby making the deformation holes easy to deform and improving the deformation capacity of the pressure plate body.

[0043] Furthermore, the central ring area 6 is in the shape of a curved surface that gradually rises from the inside to the outside. In this technical solution, the central ring area is in the shape of a curved surface that gradually rises from the inside to the outside, which is conducive to transferring the force at the center to the outer edge, is easy to deform, and has good stability.

[0044] Furthermore, the annular deformation zone 7 is in the shape of an arcuate surface that curves downward from the inside to the outside, or in the shape of an inclined surface that tilts downward from the inside to the outside; and the thickness of the annular pressure zone 8 is greater than that of the central annular zone 6 and the annular deformation zone 7. In this technical solution, the annular deformation zone is configured as an arcuate surface that curves downward from the inside to the outside, or in the shape of an inclined surface that tilts downward from the inside to the outside, which facilitates the annular deformation zone to transfer the force applied at the upper end to the lower end; and the thickness of the annular pressure zone is greater than that of the central annular zone and the annular deformation zone, which improves the structural strength of the annular pressure zone, ensuring that the annular pressure zone remains stable when the annular pressure strip acts on the suction cup body. At the same time, a transition is formed between the annular pressure zone and the annular deformation zone, which has the effect of enhancing the deformation effect to a certain extent. Example 2:

[0045] like Figures 5 and 6 The two suction cup assemblies shown in Figures 11 and 12 include a suction cup body 200 and a pressure cup 100. The suction cup body 200 includes a pressing frame and an elastic colloid 11 covering the pressing frame. The lower end surface of the elastic colloid 11 is formed into an arched adsorption cavity 12 with its center higher than the edge of the cup body 1. The multiple annular pressure strips 5 on the pressure cup 100 press against the upper end surface edge of the suction cup body 200. Figures 5 and 6 The suction cup assembly shown includes the following Figures 1 to 4 The suction cup and pressure plate shown; and Figures 11-12 The suction cup assembly shown includes the following Figures 7-10 The suction cup pressure plate shown; the pressure plate and the suction cup body are assembled through the cooperation of the connecting rod and the through hole. After assembly, the multiple annular pressure strips on the pressure plate are pressed against the edge of the upper end surface of the suction cup body. When in use, the user acts on the pressure plate, and the multiple annular pressure strips are squeezed on the suction cup body to discharge the air in the arched adsorption cavity, thereby making the suction cup body tightly adsorbed on the base surface, and the adsorption effect is better.
