Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, specifically a assembleable suction cup with a main and auxiliary three-suction cup structure, which is suitable for multi-scenario applications requiring high adsorption stability, precise assembly, and flexible expansion connections. Background Technology

[0002] Traditional suction cups are mostly single or double suction cups, which have insufficient adsorption stability. In addition, some suction cups have simple assembly structures, loose fasteners and connecting parts, and limited auxiliary connection structures, making it difficult to meet the requirements of adsorption reliability, assembly stability and expandability in various scenarios. Utility Model Content

[0003] This utility model aims to provide an assemblable suction cup. The three-suction cup combination structure (main suction cup + two auxiliary suction cups) enhances suction stability. Precise assembly is achieved using positioning holes and positioning pins, improving suction cup airtightness, maintaining suction vacuum pressure, and preventing detachment. The striped handle of the main suction cup optimizes venting. Reinforcing ribs within the main frame enhance structural strength. Inclined mounting holes and matching gaskets improve the connection stability and sag resistance of extended assembly products. This invention solves problems such as assembly deviations, structural deformation, inconvenient venting, loose extended connections, easy rotation of independent suction cups, and air leakage and detachment due to inaccurate suction cup assembly, which can damage furniture and items, and cause personal injury or other dangerous accidents.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An assemblable suction cup includes a suction cup, a main frame, a connecting shaft, a spring, and auxiliary connecting components;

[0006] The suction cup includes a main suction cup located at the top and two auxiliary suction cups located below the main suction cup. Each suction cup has positioning holes at the top and bottom, and a connecting shaft and a spring sleeved on the connecting shaft and embedded in the suction cup are provided in the middle.

[0007] The suction cup is embedded in the bottom of the main frame, and the contact surface between the suction cup and the main frame is covered with a protruding step that matches the bottom edge of the main frame. The bottom of the main frame is provided with a positioning pin corresponding to the positioning hole of the suction cup. All three suction cups are included.

[0008] The auxiliary connection assembly includes a snap fastener, a connecting block, a pin, and a threaded pin; the snap fastener is connected to the connecting shaft on the suction cup via the pin; the connecting block is installed between the vertically distributed fixing ears on the outside of the main frame via the threaded pin;

[0009] Each suction cup is also provided with a striped handle on one side for easy manual degassing, facilitating quick assembly and disassembly. Furthermore, the suction cups have a polygonal structure, with the main suction cup being a large suction cup and the dual auxiliary suction cups being small suction cups.

[0010] Furthermore, each of the suction cups is provided with four positioning holes, two of which are located at the top and two at the bottom.

[0011] Furthermore, the inner side of the main frame is provided with an inner support reinforcing rib corresponding to each suction cup, and its outer edge is provided with a suction cup contact surface that matches the outer contour of the suction cup.

[0012] Furthermore, the fastener is engaged with the suction cup's connecting shaft via a pin.

[0013] Furthermore, mounting gaskets are provided between the buckle and the main frame, and between the connecting block and the fixing ear.

[0014] Furthermore, the upper and lower fixing ears are respectively provided with mounting holes with an inclined angle, and the mounting gasket between the connecting block and the fixing ear is a gasket with an upward curvature and a step, the upward curvature of which is the same as the inclination angle of the mounting hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] Superior Adsorption Performance: It adopts a polygonal three-suction cup combination structure with a large main suction cup and small dual auxiliary suction cups. The main suction cup provides the main adsorption force, while the dual auxiliary suction cups assist in balance, which greatly improves the adsorption stability. At the same time, the striped handle on one side of the suction cup can be directly torn off to release air without additional tools, which significantly improves the adsorption operation efficiency.

[0017] Higher assembly precision: Each suction cup has two positioning holes at the top and bottom, which, together with the positioning pins on the inside of the main frame, achieve point-to-point precise assembly, avoiding component displacement caused by missing positioning in traditional assembly. At the same time, the suction cup is located at the bottom of the main body, and the contact surface between the suction cup and the main body is covered with a protruding step that matches the bottom edge of the main body, further ensuring the fit of the assembly and increasing the airtightness of the suction cup.

[0018] Stronger structure: The inner side of the main frame is equipped with internal support ribs for each suction cup, which can effectively disperse the stress transmitted to the main frame when the suction cup is adsorbing, avoid deformation of the main frame after long-term use, and extend the service life of the overall structure.

[0019] More stable extended connection: The upper and lower fixing ears are equipped with mounting holes with an inclined angle, and with special gaskets with the same upward curvature and a step, so that there is no gap when the connecting block and the fixing ears fit together, and the upward angle prevents the product from sagging; solving the problem of product sagging when assembling products with traditional straight holes and flat gaskets; at the same time, the mounting gasket between the buckle and the main frame can enhance the tightness of the snap-fit, further improving the overall connection reliability.

[0020] Excellent ease of assembly and disassembly: Each component is assembled using standardized connectors such as connecting shafts, pins, and threaded nails. No complicated tools are required for assembly and disassembly, making it suitable for rapid maintenance and parts replacement in various scenarios. Attached Figure Description

[0029] Example:

[0030] like Figure 1 , 2 As shown in Figure 3, the assemblable suction cup of this utility model adopts a polygonal three-suction cup structure with a main suction cup and two auxiliary suction cups. The specific structure and assembly process are as follows:

[0031] The suction cup 2 includes one large main suction cup 201 and two small auxiliary suction cups 202, all of which are polygonal structures. Each suction cup has two positioning holes 203 at the top and bottom (a total of four). The middle part is pre-set with a groove for embedding the spring 4. After the spring 4 is sleeved, it is assembled with the connecting shaft 3. A striped handle 204 is integrally formed on one side of each suction cup.

[0032] The inner side of the main frame 1 is provided with internal support reinforcing ribs 102 corresponding to the three suction cups, and the outer edge is machined with a suction cup mating surface 103 that perfectly matches the outer contour of the suction cup. A positioning pin 101 is fixedly provided in the positioning hole 203 corresponding to each suction cup. The outer side of the main frame 1 is provided with two upper and lower fixing ears 104, and the fixing ears 104 are provided with mounting holes 1041 with an inclined angle.

[0033] The auxiliary connection components include a snap fastener 5, a connecting block 6, a pin 7, a threaded pin 8, and two types of mounting gaskets (a flat gasket 901 between the snap fastener and the main frame, and a special gasket 902 with a step and an upward curve between the connecting block and the fixing lug).

[0034] Assembly process:

[0035] (1) Initial assembly of suction cup and main frame: The spring 4 is embedded in the groove in the middle of the suction cup 2. After the connecting shaft 3 is sleeved, the suction cup 2 is aligned with the positioning pin 101 on the inner side of the main frame 1, so that the positioning hole 203 of the suction cup and the positioning pin 101 are matched one by one, and the suction cup and the main frame are accurately positioned. At this time, the outer contour of the suction cup is completely in contact with the suction cup contact surface 103 of the main frame.

[0036] (2) Fastener fixing: Place the flat shim 901 between the fastener 5 and the main frame 1, and use the pin 7 to fasten the fastener 5 and the connecting shaft 3 of the suction cup 2. After tightening the pin 7, the fastener and the connecting shaft are tightly fixed to prevent the suction cup from loosening.

[0037] (3) Installation of connecting block: Place the special gasket 902 between the connecting block 6 and the upper and lower fixing ears 104, so that the upper surface of the gasket fits with the inclined mounting hole 1041 of the fixing ear. Pass the threaded nail 8 through the fixing ear, the special gasket and the connecting block in sequence. After tightening the threaded nail, the connecting block and the fixing ear are fixed without gaps and can be directly connected to external accessories.

[0038] Usage process:

[0039] During adsorption, hold the main frame and attach the three suction cups to the surface to be adsorbed. The main suction cup provides the main adsorption force, the two auxiliary suction cups assist in balance, and the internal support reinforcing ribs 102 disperse the adsorption stress. If expansion connection is required, simply fix the external accessories to the connecting block 6 with bolts.

[0040] The present invention and its embodiments have been described above. The accompanying drawings are only preferred embodiments of the present invention, and the actual structure can be adjusted according to the claims (such as the specific shape of the polygonal suction cup, the inclination angle of the mounting holes, etc.). If those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
