A flat-frame suction cup

Abstract

This utility model discloses a flat-frame suction cup, including a housing, a driving unit on one side of the housing, and an adsorption assembly on the other side of the housing. The adsorption assembly includes a disc body and a rubber disc mounted on the disc body. A piston chamber is also provided in the middle of the disc body, and a piston is provided in the piston chamber. When the rubber disc is connected to a substrate, the driving unit causes the piston to move within the piston chamber, thereby creating a vacuum on the side of the piston chamber facing the substrate. In summary, because the adsorption assembly is provided on one side of the housing, and a piston chamber is provided within the disc body, and the piston in the piston chamber moves in conjunction with the driving unit, when the rubber disc contacts the substrate surface, the outward-moving piston can create a vacuum zone between the rubber disc and the substrate surface, thereby assisting the connection between the rubber disc and the substrate. In particular, the entire rubber disc does not move outward when the vacuum zone is formed, making this suction cup more novel and unique in structure than existing suction cups.

Description

Technical Field

[0001] This utility model relates to the field of hardware products technology, specifically a flat frame suction cup. Background Technology

[0002] Currently, suction cups with frames generally include a frame, a suction cup body covering the frame, a connecting rod on the back of the frame, a suction cup cover fitted onto the connecting rod and covering the back of the suction cup body, and a hanger on the back of the suction cup cover connected to the connecting rod for applying tension and pressure to the frame. When it is necessary to attach a flat-framed suction cup to a substrate surface, the suction cup is first attached to the substrate surface. An external force pulls the connecting rod upward, causing the frame to deform, forming a vacuum cavity between the suction cup body and the substrate surface. At the same time, the suction cup cover, under the action of external force, transmits force reaction to the suction cup body, restricting its deformation. Outside air cannot enter the vacuum cavity. Under their interaction, the suction cup body adheres to the substrate surface. It can be seen that existing suction cups basically generate a vacuum by deforming the suction cup soft body, resulting in insufficient suction force and inability to stably and reliably adhere to the substrate surface. Utility Model Content

[0003] The purpose of this invention is to provide a flat-frame suction cup to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flat-frame suction cup, comprising a housing, a driving part on one side of the housing, and an adsorption assembly on the other side of the housing; the adsorption assembly comprises a disc body and a rubber disc mounted on the disc body, a piston chamber in the middle of the disc body, and a piston in the piston chamber; when the rubber disc is connected to the substrate, the driving part causes the piston to move in the piston chamber, so that a vacuum is formed on the side of the piston chamber facing the substrate.

[0005] As a preferred technical solution of this utility model: a spring is also provided in the piston chamber, and the piston is reset by means of the spring.

[0006] As a preferred technical solution of this utility model: the outer wall surface of the piston is further provided with a sealing ring, and the sealing ring contacts the inner wall surface of the piston cavity.

[0007] As a preferred technical solution of this utility model: the side of the rubber disc away from the shell is coated with glue.

[0008] As a preferred technical solution of this utility model: the driving part is eccentrically disposed with respect to the housing, and the lower end of the driving part abuts against the outer wall surface of the housing; by moving the upper end of the driving part to separate the upper end of the driving part from the housing, the piston is moved.

[0009] As a preferred technical solution of this utility model: the piston is provided with a connecting rod, and the connecting rod is also provided with a connecting hole, and the driving part is also provided with a pin hole; the driving part and the piston are connected by passing the pin through the connecting hole and the pin hole.

[0013] As a preferred technical solution of this utility model, a protrusion is provided on the outer circumferential surface of the driving part.

[0014] The beneficial effects of this utility model by adopting the above technical solution are as follows: Since an adsorption component is provided on one side of the shell and a piston chamber is provided in the disc body, and the piston in the piston chamber is linked with the drive unit, when the adhesive disc contacts the surface of the substrate, the outwardly moving piston can form a vacuum area between the adhesive disc and the surface of the substrate, thereby assisting the connection between the adhesive disc and the substrate; in particular, when the vacuum area is formed, the entire adhesive disc will not move outward, so that the suction cup is more novel and unique in structure than the existing suction cups.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0024] Please see Figure 1-7 This utility model provides an embodiment of a flat-frame suction cup, comprising a housing 1, a driving part 2 on one side of the housing 1, and an adsorption assembly 3 on the other side of the housing 1; the adsorption assembly 3 includes a disc body 30 and a rubber disc 31 mounted on the disc body 30, a piston chamber 35 in the middle of the disc body 30, and a piston 33 in the piston chamber 35; when the rubber disc 31 is connected to the substrate, the driving part 2 causes the piston 33 to move in the piston chamber 35, so that a vacuum is formed on the side of the piston chamber 35 facing the substrate.

[0025] In summary, since an adsorption component 3 is provided on one side of the housing 1 and a piston chamber 35 is provided in the disc body 30, and the piston 33 in the piston chamber 35 is linked with the drive unit 2, when the adhesive disc 31 contacts the substrate surface, the outwardly moving piston 33 can form a vacuum area between the adhesive disc 31 and the substrate surface, thereby assisting the connection between the adhesive disc 31 and the substrate; in particular, when the vacuum area is formed, the entire adhesive disc will not move outward, making this suction cup more novel and unique than the existing suction cup structure.

[0026] Furthermore, since a spring 32 is also provided in the piston chamber 35, and the piston 33 is reset by the spring 32, when the drive unit 2 is in the opening process, the spring 32 cooperates with the drive unit 2 to reset the piston 33 and contact the vacuum state, so that the rubber disc 31 can be separated from the substrate surface.

[0027] Furthermore, since the outer wall of the piston 33 is also provided with a sealing ring 34, and the sealing ring 34 contacts the inner wall of the piston cavity 35, the sealing ring 34 is used to fill the gap between the piston 33 and the piston cavity 35, so as to ensure that the adsorption assembly 3 can quickly and reliably establish a vacuum state when the piston 33 moves.

[0028] In addition, since the side of the adhesive tray 31 away from the housing 1 is coated with adhesive, the adhesive can be used to help fix the position of the adhesive tray 31 relative to the substrate surface when they first come into contact. At the same time, the adhesive can also be used to help connect the adhesive tray 31 to the substrate surface. The adhesive is the kind commonly used for suction cups, such as blister adhesive, epoxy resin and silicone adhesive.

[0029] Implementation method one: such as Figure 1-4 As shown: the driving part 2 is eccentrically disposed with respect to the housing 1, and the lower end of the driving part 2 abuts against the outer wall surface of the housing 1; by moving the upper end of the driving part 2 to separate the upper end of the driving part 2 from the housing 1, the piston 33 is moved.

[0030] To facilitate assembly and disassembly, the piston 33 is provided with a connecting rod 36, and the connecting rod 36 is also provided with a connecting hole 37. The drive unit 2 is also provided with a shaft pin hole 4. The drive unit 2 and the piston 33 are connected by passing the shaft pin through the connecting hole 37 and the shaft pin hole 4.

[0031] To ensure that the connecting rod 36 does not rotate axially during movement, the cross-section of the connecting rod 36 is rectangular.

[0032] In summary, after the shaft pin connects the drive unit 2 to the connecting rod 36, when it is necessary to release the vacuum state of the suction cup, one end of the drive unit 2 rotates counterclockwise along the central axis of the shaft pin, causing the piston 33 to move towards the substrate; conversely, when the drive unit 2 rotates clockwise, it drives the piston 33 to move away from the substrate, so that the adsorption assembly 3 can be reliably adsorbed onto the substrate. Based on this, the drive unit 2 can be flipped outside the housing 1 to achieve contact or separation between the adsorption assembly 3 and the substrate.

[0033] Implementation Method Two: (e.g.) Figure 5-7 As shown, unlike Embodiment 1, the driving part 2 is concentrically arranged with the housing 1, and the piston 33 is moved by rotating the driving part 2 along the central axis of the housing 1. Therefore, the adsorption assembly 3 can perform adsorption or de-adsorption by rotating the driving part 2, and the driving part 2 can completely fit against the outside of the housing 1 during rotation, making the suction cup structure more aesthetically pleasing.

[0034] Specifically, the drive unit 2 has an internal threaded hole 5 at its center, and the piston 33 is connected to the internal threaded hole 5 by an external threaded post 38. Therefore, the use of threaded connection can not only complete the linkage between the drive unit 2 and the piston 33, but also reduce the processing difficulty and processing cost of the equipment.

[0035] Furthermore, a protrusion 6 is provided on the outer circumferential surface of the drive unit 2. Therefore, the protrusion 6 can be used to prevent the user from causing the drive unit 2 to slip when rotated.

[0036] When the suction cup creates a vacuum, such as Figure 7 As shown, after the piston 33 moves into the piston cavity 35, the area between the inner wall of the piston cavity 35 and the area between the piston 33 and the substrate is a vacuum region.

[0037] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
