Description

Technical Field

[0001] This utility model relates to the field of suction cup sealing technology, specifically a suction cup sealing ring. Background Technology

[0002] Suction cup sealing rings are ring-shaped sealing components that utilize the principle of negative pressure to form a seal by adhering to the contact surface with a soft and elastic material. They can be adsorbed onto smooth surfaces to achieve functions such as leak prevention and fixation.

[0003] The sealing ring at the bottom of existing suction cups is usually made of rubber as a single structure with protrusions at the contact point with the workpiece surface. This sealing method mainly relies on the elasticity of the rubber to achieve a seal with the workpiece surface. However, when the workpiece surface is extremely rough, this sealing method is difficult to achieve a good sealing effect. Once the seal fails, the suction cup will not work properly. In addition, some suction cups have tried to use soft and highly elastic sponge to make the sealing ring to solve the above problems. Although sponge sealing rings can provide better sealing performance, the sponge material itself has low strength, making it easy to be damaged, which increases the cost of use. Utility Model Content

[0004] The purpose of this invention is to provide a suction cup sealing ring to solve the problem mentioned in the background art, where the bottom sealing ring of the suction cup is mostly a rubber integral structure that relies on elasticity to seal with the workpiece surface. When the workpiece surface is rough, the sealing effect is poor and the suction cup is prone to failure. Some suction cups use soft and elastic sponge as the sealing ring to solve this problem, but the sponge has low strength and is easily damaged, which increases the cost of use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a suction cup sealing ring, comprising a suction cup base, wherein an adsorption component is provided at the bottom of the suction cup base, and a workpiece is connected to the suction cup base through the adsorption component;

[0006] The adsorption assembly includes an integrated sealing ring disposed on the inner wall of the bottom of the suction cup base. The integrated sealing ring is hollow inside. A valve is disposed on one side of the suction cup base. The bottom of the valve is connected to the integrated sealing ring.

[0007] The integrated sealing ring is provided with a retaining ring, which is provided with several buckles, and the suction cup base is provided with several slots corresponding to the buckles.

[0008] Using the above technical solution, the suction cup base serves as the basic support structure of the overall device, providing installation positions for other components. Simultaneously, it facilitates the transport of workpieces via the suction assembly. The integrated sealing ring on the inner wall of the bottom of the suction cup base is hollow, forming a sealed space with the workpiece surface. Made of elastic material, the integrated sealing ring can be pressurized or depressurized via valve one to achieve positive, negative, or zero pressure to accommodate different workpieces. A retaining ring one engages with the inner wall of the bottom of the suction cup base to compress the sealing ring. A buckle one on the retaining ring one engages with a slot one on the suction cup base, securely fixing the integrated sealing ring to the bottom of the suction cup base.

[0009] Preferably, the adsorption assembly includes a rolled edge extrusion sealing ring disposed on the inner wall of the bottom of the suction cup base. The rolled edge extrusion sealing ring includes an upper rolled edge and a lower rolled edge. A second buckle is disposed inside the rolled edge extrusion sealing ring. Several second buckles are disposed on the second buckle. Several second slots corresponding to the second buckles are disposed on the suction cup base.

[0010] Using the above technical solution, the rolled edge extrusion sealing ring is located on the bottom inner wall of the suction cup base. After the upper and lower rolled edges of the rolled edge extrusion sealing ring are rolled up, they are squeezed tightly by the second buckle on the second buckle ring to form a stable hollow area inside. The second buckle on the second buckle ring also cooperates with the corresponding second slot on the suction cup base to firmly fix the rolled edge extrusion sealing ring to the bottom of the suction cup base.

[0011] Preferably, the inside of the rolled edge extrusion sealing ring is a hollow area, and a second valve is provided on one side of the suction cup base, with the bottom of the second valve connected to the hollow area.

[0012] Using the above technical solution, the rolled edge extrusion sealing ring is made of elastic material, and air can be added or extracted to the hollow area through valve two to achieve positive pressure, negative pressure or zero pressure state inside to adapt to different workpieces.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the suction cup sealing ring:

[0014] 1. The integrated sealing ring in the suction cup base and adsorption assembly forms a sealed space with the workpiece surface. The integrated sealing ring is hollow and made of elastic material. It can be filled or evacuated through valve one to make the interior positive, negative or zero pressure. This flexible pressure adjustment method can adapt well to different workpieces. In particular, the negative pressure state is more effective for adsorption of rough workpieces. Secondly, the buckle one cooperates with the inner wall of the bottom of the suction cup base to compress the integrated sealing ring. The buckle one on buckle one cooperates with the slot one on the suction cup base to firmly fix the integrated sealing ring to the bottom of the suction cup base, ensuring the stability and reliability of the structure and ensuring the smooth operation of adsorption and handling.

[0015] 2. The rolled-edge extrusion sealing ring in the adsorption assembly is tightly pressed together by the upper and lower rolled edges and the snap fasteners on the second buckle, forming a stable hollow area inside. The snap fasteners on the second buckle cooperate with the slots on the suction cup base to firmly fix the rolled-edge extrusion sealing ring to the bottom of the suction cup base, ensuring the stability of the structure. Furthermore, the rolled-edge extrusion sealing ring is made of elastic material, and the hollow area can be filled or evacuated through the second valve to achieve positive pressure, negative pressure, or zero pressure inside, which can adapt to different workpieces. In particular, the negative pressure state is more conducive to adsorbing workpieces with rough surfaces, enhancing the applicability and effectiveness of adsorption. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1-5 This utility model provides a technical solution: a suction cup sealing ring, including a suction cup base 1, an adsorption component 3 is provided at the bottom of the suction cup base 1, and a workpiece 2 is connected to the suction cup base 1 through the adsorption component 3;

[0025] The adsorption assembly 3 includes an integrated sealing ring 31 disposed on the inner wall of the bottom of the suction cup base 1. The integrated sealing ring 31 is hollow inside. A valve 32 is disposed on one side of the suction cup base 1. The bottom of the valve 32 is connected to the integrated sealing ring 31.

[0026] The integrated sealing ring 31 is provided with a retaining ring 33, and the retaining ring 33 is provided with several buckles 313. The suction cup base 1 is provided with several slots 34 corresponding to the buckles 313.

[0027] Referring to the attached diagrams in the instruction manual Figures 1-5 As shown, firstly, the suction cup base 1 serves as the basic support structure of the entire device, providing installation positions for other components. Simultaneously, the workpiece 2 is transported through the suction assembly 3. Secondly, the integrated sealing ring 31 on the inner wall of the bottom of the suction cup base 1 is hollow inside, forming a sealed space with the surface of the workpiece 2. The integrated sealing ring 31 is made of elastic material and can be filled or depressurized through the valve 32 to achieve positive pressure, negative pressure, or zero pressure to adapt to different workpieces 2. In addition, the retaining ring 33 can cooperate with the inner wall of the bottom of the suction cup base 1 to compress the sealing ring. The buckle 313 on the retaining ring 33 cooperates with the slot 34 on the suction cup base 1 to firmly fix the integrated sealing ring 31 to the bottom of the suction cup base 1.

[0028] Working principle: When using this suction cup sealing ring, first install the integrated sealing ring 31 onto the inner wall of the bottom of the suction cup base 1. Then install the retaining ring 33. The retaining ring 33 engages with the inner wall of the bottom of the suction cup base 1, pressing the integrated sealing ring 31. The buckle 313 on the retaining ring 33 is then engaged into the corresponding slot 34 at the bottom of the suction cup base 1, thus firmly fixing the integrated sealing ring 31 to the bottom of the suction cup base 1. The suction cup base 1 is connected to the workpiece 2 through the integrated sealing ring 31, forming a sealed space. This can be achieved manually or electrically. The air pump is driven to remove the gas from the sealed space, creating a negative pressure inside. Under the action of air pressure, the suction cup base 1 and the workpiece 2 are tightly connected. At this time, the suction cup can be lifted to start moving the workpiece 2. In addition, the integrated sealing ring 31 is a hollow sealed ring made of elastic material. Through the air valve 32 on the suction cup base 1, air can be added or removed from its hollow interior, so that the interior of the integrated sealing ring 31 is in a positive pressure, negative pressure or zero pressure state. Among them, the negative pressure state is more conducive to adsorbing the rough surface of the workpiece 2.

[0029] Example 2

[0030] like Figures 1-5As shown, the difference between this embodiment and embodiment one is that the adsorption component 3 includes a rolled edge extrusion sealing ring 35 disposed on the inner wall of the bottom of the suction cup base 1. The rolled edge extrusion sealing ring 35 includes an upper rolled edge 36 and a lower rolled edge 37. A second buckle 310 is disposed inside the rolled edge extrusion sealing ring 35. Several second buckles 314 are disposed on the second buckle 310. Several second slots 311 corresponding to the second buckles 314 are disposed on the suction cup base 1.

[0031] The inside of the rolled edge extrusion sealing ring 35 is a hollow area 38. A valve 2 39 is provided on one side of the suction cup base 1, and the bottom of the valve 2 39 is connected to the hollow area 38.

[0032] Referring to the attached diagrams in the instruction manual Figures 1-5 As shown, firstly, the rolled edge extrusion sealing ring 35 is located on the bottom inner wall of the suction cup base 1. After the upper rolled edge 36 and lower rolled edge 37 of the rolled edge extrusion sealing ring 35 are rolled up, they are squeezed tightly by the buckle 314 on the second buckle ring 310 to form a stable hollow area 38. The rolled edge extrusion sealing ring 35 is made of elastic material, and the hollow area 38 can be filled or evacuated by the valve 39 to achieve positive pressure, negative pressure or zero pressure to adapt to different workpieces 2. Secondly, the buckle 314 on the second buckle ring 310 also cooperates with the corresponding slot 311 on the suction cup base 1 to firmly fix the rolled edge extrusion sealing ring 35 to the bottom of the suction cup base 1.

[0033] Working principle: When using this suction cup sealing ring, firstly, install the rolled edge extrusion sealing ring 35 onto the bottom inner wall of the suction cup base 1. Then, roll up the upper rolled edge 36 and the lower rolled edge 37 of the rolled edge extrusion sealing ring 35, and then install the second retaining ring 310. The second buckle 314 on the second retaining ring 310 presses the upper rolled edge 36 and the lower rolled edge 37, making the upper rolled edge 36 and the lower rolled edge 37 fit tightly together, so that a hollow area 38 is formed inside the rolled edge extrusion sealing ring 35. Then, the second buckle 314 on the second retaining ring 310 is inserted into the second slot 311 at the bottom of the suction cup base 1, so that the rolled edge extrusion sealing ring 35 is securely installed on the suction cup. At the bottom of the base 1, the suction cup base 1 forms a sealed space with the surface of the workpiece 2 through the edge-pressing sealing ring 35. A manually or electrically driven air pump removes the gas from this sealed space, creating a negative pressure inside. Under this air pressure, the suction cup base 1 and the workpiece 2 are tightly connected, allowing the workpiece 2 to be lifted and moved. Furthermore, the hollow area 38 inside the edge-pressing sealing ring 35 can be filled or evacuated using valve 39, allowing the inside of the edge-pressing sealing ring 35 to be in a positive, negative, or zero-pressure state. A negative pressure state is more conducive to adsorbing workpieces with rough surfaces like the workpiece 2. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
