Description

Technical Field

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

[0002] Suction cups are household items that are fixed to a base surface by adhering to it and forming a vacuum cavity in the middle, using the pressure difference between the inside and outside. They are usually attached to walls, cabinets, etc. for hanging items and are widely used because of their ease of use and flexible relocation.

[0003] Currently used suction cups generally consist of a frame and an elastic disc. The elastic disc is formed by secondary injection molding and covers the frame. During use, the pressure component engages with the connecting parts on the frame to apply pressure to the suction cup, thereby pressing the elastic disc onto the base surface. At this point, the suction cup frame supports and shapes the elastic disc covering it, while simultaneously transmitting force to expel air from the elastic disc and flattening the frame to press and adhere the disc to the base surface. However, traditional frames have poor elastic deformation capabilities. During use, it is difficult for elastic deformation to occur around the connecting parts on the frame, making it difficult to press the suction cup frame down, or even causing it to break and rendering the suction cup unusable. Furthermore, traditional frames have notches extending towards the center on their outer edges, giving the frame edges a gripping tendency to ensure a greater vacuum. However, this results in poor pressure strength between adjacent notches, hindering the frame's elastic recovery and making it prone to deformation or breakage, thus affecting the suction cup's adsorption capacity. In addition, because the elastic disc is relatively soft, the rebound force of the skeleton is greater than the elastic recovery force of the elastic disc during use. At the same time, the friction between the elastic disc and the base surface will prevent the elastic disc from shrinking back. In particular, the edge of the skeleton is divided into several pressure plates by notches, which makes it easy for the edge of the skeleton to separate or shift from the edge of the disc, resulting in delamination. After delamination, the skeleton separates from the elastic disc, and the suction cup loses its function. Utility Model Content

[0004] The purpose of this invention is to provide a suction cup frame that is tightly connected to an elastic disc covering the outside of the frame, thereby improving the suction effect of the suction cup.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A suction cup frame includes a body with a connecting portion on the upper surface for connection to the outside. The body has a plurality of elongated holes, the connecting portion is located in the middle of the body, the elongated holes are arranged in a circumferential array around the connecting portion, the distance between one end of each elongated hole and the connecting portion is 0-3 mm, and reinforcing ribs are provided between adjacent elongated holes. The lower surface of the body includes a top surface and sidewalls, the sidewalls are connected around the top surface, and the radius of the top surface is not greater than 3 / 5 of the radius of the body.

[0007] Preferably, the reinforcing ribs are elongated protrusions, and the reinforcing ribs are arranged in a circumferential array on the body.

[0008] Preferably, the length of the reinforcing rib is 5-25mm, and the reinforcing rib is located on the side of the body near the outer edge of the body.

[0009] Preferably, the length of the elongated hole is 5-22 mm, and the radius of the body is 20-35 mm.

[0010] Preferably, the elongated holes are provided in the form of 8-22 holes.

[0011] Preferably, the sidewall is composed of several inclined surfaces joined together, with smooth transitions between the inclined surfaces forming a bowl-shaped skeleton.

[0012] Preferably, the connecting part includes a boss and a receiving part, the receiving part is disposed on the upper surface of the boss, the boss and the body are smoothly connected, and the elongated holes are circumferentially arrayed around the boss.

[0013] Preferably, the boss is disposed on the upper side of the top surface and matches the dimensions of the top surface; the top surface is a plane or an arc surface that is concave towards the center.

[0014] Preferably, the receiving part is a hollow protrusion, and there are snap-fit ​​edges on opposite sides of the protrusion.

[0015] Preferably, the receiving part consists of two support plates disposed opposite to each other on the boss, with outwardly protruding latches on the support plates, and a stepped hole penetrating the body is provided on the boss between the two support plates.

[0016] In the above technical solution, the suction cup skeleton of this application has elongated holes around the connecting part. The elongated holes extend from the root of the connecting part to the outer edge of the skeleton body, which enhances the elastic deformation capability of the skeleton. It is easier to deform and more elastically recover than traditional skeletons, thereby making the elastic disc body flatter and enhancing the suction capacity of the suction cup. At the same time, after the elastic disc body covers the skeleton, it forms a covering edge around the connecting part on the upper part of the body. At this time, the elastic disc body passes through the elongated holes and connects with the elastic disc body on the lower side of the body, thereby effectively avoiding the problem of the covering edge curling or detachment. Meanwhile, the elastic disc body near the outer edge of the body passes through the elongated holes longitudinally and connects its upper and lower sides together. The sidewall of the elongated hole forms a radial blocking effect on the elastic disc body. When the skeleton rebounds under the action of deformation force, the sidewall of the elongated hole will simultaneously pull the elastic disc body to rebound together, thereby avoiding the separation or displacement of the skeleton edge and the elastic disc edge due to the inconsistency between the rebound force of the skeleton and the rebound force of the disc body, resulting in delamination. Furthermore, the elongated hole extends from the root of the connector to the outer edge of the skeleton body, increasing the contact area between the skeleton and the elastic suction cup, making the connection between the two tighter, and allowing the skeleton to better support the elastic disc and transmit pressure.

[0017] The purpose of this invention is to provide a suction cup in which the skeleton of the suction cup is tightly connected to the elastic disc body covering the outside of the skeleton, so that the suction cup has a good adsorption effect and a long service life.

[0018] To achieve the above objectives, the present invention adopts the following technical solution:

[0019] A suction cup includes an elastic disc body and a frame, wherein the frame is the suction cup frame described in the above technical solution, and the elastic disc body extends longitudinally through the elongated hole to connect the upper and lower sides of the elastic disc body; the elastic disc body is not higher than the lower side of the connecting part.

[0020] In the above technical solution, the elastic disc covers the skeleton and passes longitudinally through the elongated hole, intersecting with the skeleton. This makes the connection between the disc and the skeleton body tighter, preventing the edge of the skeleton from detaching from the edge of the disc and thus extending the lifespan of the suction cup. Simultaneously, the skeleton provides better support for the disc, allowing the suction cup to maintain good adsorption capacity. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1 to 6As shown, a suction cup frame includes a body 1, which is bowl-shaped with a higher center and lower edges, and has a radius of 20-35mm. A connecting part 2 for external connection is provided on the upper surface of the body 1. The connecting part 2 extends through an external adhesive covering the body 1 and connects to a hanging device, which can be any of a hook, shelf, connector, storage box, or mop bucket. The main body 1 is also provided with several elongated holes 3, which penetrate the upper and lower surfaces of the main body 1, and there are 8 to 22 elongated holes. The connecting part 2 is located in the middle of the main body 1, and the elongated holes 3 are arranged in a circumferential array around the connecting part 2. Preferably, there are 16 elongated holes 3. The lower surface of the main body includes a top surface 12 and a side wall 13. The side wall 13 is connected around the top surface 12, and the radius of the top surface is not greater than 3 / 5 of the radius of the main body. This enhances the elastic deformation capability of the skeleton, making it easier to deform and more elastically recover than the traditional skeleton. When pressed, it can support the elastic disc to be more flat, which greatly enhances the suction ability of the suction cup. The distance d1 between one end of the elongated hole 3 and the connecting part 2 is 0-3mm, and the distance d2 between the other end of the elongated hole 3 and the outer edge 11 of the body 1 is 0.5-3mm. The elongated hole 3 allows the elastic disc to pass longitudinally through the elongated hole 3 and be covered and fixed on the skeleton when the skeleton is coated with glue, and connects the upper and lower sides of the elastic disc together. After the elastic disc is wrapped around the skeleton, it forms a wrapping edge around the connecting part on the upper part of the body. At this time, the elastic disc passes through the elongated hole 3 and connects to the elastic disc on the lower side of the body 1, thus effectively avoiding the problem of the wrapping edge curling up. At the same time, the elastic disc near the outer edge of the body 1 passes through the elongated hole 3 longitudinally and connects its upper and lower sides together. The sidewall of the elongated hole 3 forms a radial blocking effect on the elastic disc. When the skeleton rebounds under the action of deformation force, the sidewall of the elongated hole 3 will pull the elastic disc to rebound together, thus avoiding the separation or displacement of the skeleton edge and the edge of the elastic disc due to the inconsistency between the rebound force of the skeleton and the rebound force of the disc, resulting in delamination. At the same time, the elongated holes 3 are evenly arranged on the body 1 in the circumference, so that the deformation force of the body 1 is evenly transmitted to the elastic disc, thereby making the supporting and compressive force of the edge of the body 1 on the edge of the elastic disc uniform and stable. Further, the length of the elongated hole is preferably 5-22mm.

[0030] A reinforcing rib 4 is provided between adjacent elongated holes 3. The reinforcing rib is a long strip protrusion with a length of 5-25mm, and the reinforcing rib is arranged in a circumferential array on the side of the body near the outer edge of the body. This can enhance the strength of the skeleton and make the deformation force of the skeleton more evenly transmitted. At the same time, it can strengthen the connection between the elastic disc and the body 1, and further prevent the elastic disc from falling off the body 1.

[0031] In one embodiment, the sidewall 13 is formed by splicing together several inclined surfaces 5, with smooth transitions between the inclined surfaces 5 forming a bowl-shaped skeleton. The connecting part 2 includes a boss 6 and a receiving part 7. The receiving part 7 is disposed on the upper surface of the boss 6, and the boss 6 is disposed on the upper surface of the body 1 and smoothly connected to the body 1. The inclined surfaces 5 surround the boss 6 and connect with the boss 6. The boss 6 is a circular base, or it can be polygonal. The boss 6 is disposed on the upper side of the top surface 12, and the size of the boss 6 is not larger than the size of the top surface 12. Preferably, the size of the boss 6 matches that of the top surface 12. The lower surface of the top surface 12 is a plane or an arc surface that is concave towards the center and contacts the lower side of the external colloid. The boss 6 increases the connection between the receiving part 7 and the body 1, preventing the connection strength of the receiving part 7 from being affected during the deformation of the body 1. Furthermore, elongated holes 3 are arranged circumferentially around the boss 6.

[0032] In another preferred embodiment, the connecting part 7 is a protrusion with a snap-fit ​​structure, that is, it is connected to the external hanger by snap-fit ​​and / or plug-in method. Specifically, the receiving part 7 is a hollow protrusion 8, and snap-fit ​​edges 81 are provided on opposite sides of the protrusion 8. The external hanger is connected by snapping onto the snap-fit ​​edges 81 through a slot.

[0033] In a preferred embodiment, the receiving part 7 may further consist of two support plates 9 oppositely disposed on the boss 6. Each support plate 9 has an outwardly protruding latch 91, and the external hanging part is secured to the latch 91 via a slot, thus achieving connection. Further, a stepped hole 10 penetrating the body 1 is provided on the boss 6 between the two support plates 9. A support rod is sealed within the stepped hole 10, and the support rod moves to the inside of the suction cup and pushes open the suction cup, facilitating the quick release of the suction cup's adsorption state. When the suction cup is in the adsorption state, the support rod is only sealed at the stepped hole 10; further still, the elastic disc does not protrude above the upper surface of the boss 6.

[0034] The aforementioned frame needs to be wrapped with an elastic disc during use. When in use, the elastic disc is placed against the base surface, and pressure is applied to ensure it adheres firmly, expelling any air between the disc and the base. Subsequently, the center of the frame body, due to deformation, tends to spring back, pulling the bottom of the disc upwards to form a vacuum chamber. The edge of the elongated hole causes the elastic disc to follow the frame, converging and springing towards the center, thus achieving a tight adhesion to the base surface. This results in a high vacuum level in the suction cup's vacuum chamber and strong adhesion of the disc. Furthermore, it prevents delamination, extending the suction cup's lifespan.

[0035] like Figures 5 to 6As shown, this application also provides a suction cup, including an elastic disc body 11 and a frame. The lower surface of the elastic disc body 11 forms an adsorption cavity that is deep in the middle and shallow around the edges. The elastic disc body 11 covers the frame, which is the suction cup frame described in the above-mentioned technical solution. Specifically, the suction cup frame includes a body 1, which is bowl-shaped with a higher center and lower edges, and has a radius of 20-35mm. A connecting part 2 for connecting to the outside is provided on the upper surface of the body 1. The connecting part 2 passes through the external adhesive covering the body 1 and connects to a hanging part, which can be any of a hook, shelf, connector, storage box, or mop bucket. The main body 1 is also provided with several elongated holes 3, which penetrate the upper and lower surfaces of the main body 1, and there are 14-18 elongated holes. The connecting part 2 is located in the middle of the main body 1, and the elongated holes 3 are arranged in a circumferential array around the connecting part 2. Preferably, there are 16 elongated holes 3, which enhances the elastic deformation capability of the skeleton. It is easier to deform and more easily recover elastically than the traditional skeleton. When pressed, it can support the elastic disc to be more flat, which greatly enhances the suction capacity of the suction cup. The distance between one end of the elongated hole 3 and the connecting part 2 is 0-3mm, and the distance d1 between the other end of the elongated hole 3 and the outer edge 11 of the main body 1 is 0.5-3mm. After the elastic disc passes through the elongated hole 3 longitudinally, it covers and is fixed to the main body 1, and the elastic disc is not higher than the lower side of the connecting part, so that the upper and lower sides of the elastic disc are connected together. After the elastic disc is wrapped around the skeleton, it forms a wrapping edge around the connecting part on the upper part of the body 1. At this time, the elastic disc passes through the elongated hole 3 and is connected to the elastic disc on the lower side of the body 1, thus effectively avoiding the problem of the wrapping edge curling up. At the same time, the elastic disc near the outer edge of the body 1 passes through the elongated hole 3 longitudinally and connects its upper and lower sides together. The sidewall of the elongated hole 3 forms a radial blocking effect on the elastic disc. When the skeleton rebounds under the action of deformation force, the sidewall of the elongated hole 3 will pull the elastic disc to rebound together, thus avoiding the separation or displacement of the skeleton edge and the edge of the elastic disc due to the inconsistency between the rebound force of the skeleton and the rebound force of the disc, resulting in delamination. At the same time, the elongated holes 3 are evenly arranged on the body 1 in the circumference, so that the deformation force of the body 1 is evenly transmitted to the elastic disc, thereby making the supporting and compressive force of the edge of the body 1 on the edge of the elastic disc uniform and stable.

[0036] This embodiment is merely an illustration of the concept and implementation of this utility model, and is not intended to limit it. Under the concept of this utility model, the technical solution without substantial changes is still within the protection scope.
