Description

Technical Field

[0001] The utility model belongs to the field of electric suction cups, in particular to an electric suction cup capable of sucking a rough surface. Background Art

[0002] On construction sites, electric suction cups are often used to move materials, such as tiles. The structure of existing electric suction cups includes a rigid disc body, a ring-shaped rubber plate is provided at the bottom of the disc body, and the rubber plate is made of rubber or silicone. A U-shaped handle is provided on the upper side of the disc body, and a vacuum pump is provided in the handle. The suction end of the vacuum pump is connected to the inner hole of the rubber plate. Its working principle is to place the electric suction cup on the material with the rubber plate facing the material, and use the suction force generated by the vacuum pump to combine the electric suction cup with the material. However, it is found during use that the existing electric suction cup is only suitable for use on materials with smooth surfaces. For materials with a rough surface, that is, materials with a rough or uneven surface, the electric suction cup cannot be used because it is difficult to seal between the rubber plate and the material. This limits the scope of application of the electric suction cup. Utility Model Content

[0003] The purpose of the utility model is to provide an electric suction cup which can absorb a rough surface. The utility model has the advantages of wide application range and convenient maintenance.

[0004] The technical solution of the utility model is: an electric suction cup that can absorb rough surfaces, including a rigid disc body, an annular rubber plate is provided at the bottom of the disc body, a handle is provided on the upper side of the disc body, an air pump is provided in the handle, the suction end of the air pump is connected to the inner hole of the rubber plate, an annular foam plate is provided at the bottom of the rubber plate, the foam plate is made of flexible material, and the outer side of the foam plate is provided with a first flange that extends upward and wraps part of the rubber plate.

[0005] In the aforementioned electric suction cup that can adsorb rough surfaces, a plurality of annular air grooves and a plurality of linear air grooves are provided on the bottom surface of the rubber plate, the plurality of annular air grooves are coaxial with the inner hole of the rubber plate, the plurality of linear air grooves are evenly distributed circumferentially around the axis of the inner hole of the rubber plate, and one end of the linear air groove passes through all the annular air grooves and then connects to the inner hole of the rubber plate.

[0006] In the aforementioned electric suction cup capable of sucking the rough surface, a second flange pointing upward is provided at the outer edge of the rubber plate, and an annular groove into which the cup body is inserted is provided on the inner side of the second flange.

[0007] In the aforementioned electric suction cup that can absorb the rough surface, a conical surface is provided on the second flange, the upper end of the conical surface is connected to the top surface of the second flange, the lower end of the conical surface is connected to the outer side surface of the second flange, and the first flange extends upward and wraps part of the conical surface.

[0008] In the aforementioned electric suction cup capable of adsorbing the rough surface, a circular lip is provided on the bottom surface of the rubber plate, the cross section of the lip is a right-angled triangle, a right-angled step is formed on the outer side of the lip, and the foaming plate is located inside the right-angled step.

[0009] In the aforementioned electric suction cup capable of sucking the rough surface, the foam plate is made of foam rubber.

[0010] Compared with the prior art, the present invention mainly makes the following improvements on the basis of the existing electric suction cup: 1) A detachable foam plate is added to the outer edge of the rubber plate. When the electric suction cup is used for rough materials, the high flexibility of the foam plate is used to fill the uneven surface of the material, so as to achieve the seal between the rubber plate and the material, so that the electric suction cup can drive the rough material; when the electric suction cup is used for smooth materials, the foam plate can be retained on the rubber plate, but it is preferably removed so that the rubber plate is in direct contact with the material, which can be adsorbed more firmly, and the electric suction cup can also drive the smooth material, thereby achieving a dual-use function and a wide range of applications. 2) Since the electric suction cup contacts the material through the rubber plate or the foam plate, the rubber plate and the foam plate are easily scratched, resulting in poor sealing. The present invention sets the rubber plate and the foam plate as a snap-on detachable structure, so that the rubber plate and the foam plate are easy to replace, thereby making the electric suction cup easy to maintain. Therefore, the present invention has the advantages of a wide range of applications and easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0016] Embodiment. An electric suction cup capable of sucking a rough surface, such as Figure 1 As shown, it includes a tray body 1, a ring-shaped rubber plate 2 is provided at the bottom of the tray body 1, and the rubber plate 2 is made of rubber or silicone. A handle 3 is provided on the upper side of the tray body 1, and an air pump 12 is provided in the handle 3. The suction end of the air pump 12 is connected to the inner hole of the rubber plate 2, and the characteristics are as follows:

[0017] Three annular air grooves 6 and six linear air grooves 7 are provided on the bottom surface of the rubber plate 2. The three annular air grooves 6 are coaxial with the inner hole of the rubber plate 2, and the six linear air grooves 7 are evenly distributed circumferentially around the axis of the inner hole of the rubber plate 2. One end of the linear air groove 7 passes through all the annular air grooves 6 and connects to the inner hole of the rubber plate 2.

[0018] An annular lip 11 is provided on the bottom surface of the rubber sheet 2. The lip 11 is close to the outer edge of the rubber sheet 2. The three annular air grooves 6 are all located on the inner side of the lip 11. The cross section of the lip 11 is a right-angled triangle. The outer side of the lip 11 forms a right-angled step. When the rubber sheet 2 directly contacts the material, the lip 11 can improve the sealing between the rubber sheet 2 and the material. An upward second flange 8 is provided at the outer edge of the rubber sheet 2. An annular groove 9 inserted into the disc body 1 is provided on the inner side of the second flange 8. A conical surface 10 is provided on the second flange 8. The upper end of the conical surface 10 is connected to the top surface of the second flange 8, and the lower end of the conical surface 10 is connected to the outer side surface of the second flange 8. The disc body 1 and the rubber sheet 2 are plug-in connected. In addition, the rubber sheet 2 is made of flexible material, so the rubber sheet 2 is relatively convenient to disassemble.

[0019] A ring-shaped foam plate 4 is provided at the bottom of the rubber plate 2. The foam plate 4 is located in the right-angle step. The inner wall of the foam plate 4 is in contact with the vertical side wall of the step. The foam plate 4 is made of foam rubber. A first flange 5 is provided on the outer side of the foam plate 4. The first flange 5 extends upward and wraps part of the conical surface 10.

[0020] How to use: It is the same as the existing electric suction cup, but the difference is that when used on rough materials, the foam board 4 is kept on the rubber board 2, and the rough materials are contacted by the foam board 4, and the high elasticity and flexibility of the foam board 4 are used to fill the uneven surface of the material. When used on smooth materials, the foam board 4 is removed, and the rubber board 2 directly contacts the material. If the foam board is not removed, the foam board 4 is softer due to the rich gap structure inside the foam board 4, and the lateral rigidity is lower. Although it can be used, it is easy to slide along the surface of the material when subjected to lateral force, and more careful operation is required. When moving the material, the foam board 4 should be kept horizontal as much as possible.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
