[0001] The utility model relates to the technical field of rubber suction cups, in particular to an electric suction cup, and more particularly to a detachable vacuum suction cup. Background Art

[0002] A vacuum suction cup is a tool that adsorbs on an object through the pressure difference between the inside and outside of a rubber suction cup. In actual applications, the vacuum degree is used to maintain the attachment of two objects without separation, and the "pick up" and "put down" during the handling of glass, tiles, etc. are achieved by changing the vacuum degree of the rubber suction cup.

[0003] Some vacuum suction cups, such as the patent with the authorization announcement number CN216835495U, provide an electric suction cup. The electric suction cup includes a suction cup base and a first sealing gasket. A groove is provided on the side gasket of the first sealing gasket, and the first sealing gasket is clamped with the edge of the suction cup base through the elastic deformation of the groove of the first sealing gasket, so that the first sealing gasket and the suction cup base can be quickly installed or disassembled.

[0004] However, in actual use, when the first sealing gasket realizes adsorption due to the air extraction effect, when the object to be adsorbed is lifted by the electric suction cup, the clamping part between the first sealing gasket and the suction cup base is stressed. Since the first sealing gasket is made of rubber material, when the object adsorbed by the suction cup is too heavy, the first sealing gasket and the suction cup base are extremely easy to fall off, having a certain safety hazard.

[0030] As Figures 1-5As shown, the detachable vacuum suction cup includes a main frame 1 and a mounting plate 2. The main frame includes electronic components, a pump body, a handle 1a, and a fixing plate 1b. The electronic components and the pump body are common components inside and are not shown in the figure.

[0031] In the figure, from top to bottom are the main frame 1, the mounting plate 2, and the rubber suction cup 3. The rubber suction cup 3 is wrapped and arranged on the mounting plate 2. The rubber suction cup 3 can be made of traditional rubber material. The fixing plate 1b on the main frame 1 and the mounting plate 2 are fixedly connected by a number of first screws 4.

[0032] It should be noted here that the mounting plate 2 and the rubber suction cup 3 can form a component and be directly mounted on the fixing plate 1b of the main frame 1 through the mounting plate 2.

[0033] A flanging is provided around the rubber suction cup 3. The flanging wraps around the edge of the mounting plate 2. The flanging also includes an upper edge 31a that fits on the upper surface of the mounting plate 2. Since the rubber suction cup 3 is made of a flexible material, the flanging can be directly removed.

[0034] Below the fixing plate 1b of the main frame 1, a pressing block 11 and a number of ribs 12 located outside the pressing block 11 are provided. When the main frame 1 and the mounting plate 2 are fixed, the pressing block 11 presses against the mounting plate 2 and is located inside the inner circle of the upper edge 31a of the rubber suction cup 3, and the ribs 12 press against the upper edge 31a and clamp the upper edge 31a with the mounting plate 2 for fixation.

[0035] Preferably, the first screws 4 for fixedly connecting the main frame 1 and the mounting plate 2 are installed from top to bottom, which is convenient for disassembling the main frame 1 and the mounting plate 2, or adjusting the distance between the mounting plate 2 and the ribs 12 of the main frame 1 to achieve the disassembly and assembly of the rubber suction cup 3.

[0036] In this application, through the wrapped installation of the rubber suction cup 3 on the mounting plate 2, and the clamping arrangement of the main frame 1 and the mounting plate 2 on the upper edge 31a that fits on the upper surface of the mounting plate 2, when the vacuum suction cup is used to carry heavier objects, it is not easy for the rubber suction cup 3 and the mounting plate 2 to fall off, improving the safety during the adsorption and handling of objects, and at the same time increasing the upper limit of the weight of the adsorbed object.

[0037] As Figure 2 、 Figure 3 and Figure 5 shown, the rubber suction cup 3 is provided with an upper layer 31, a lower layer 32, and an intermediate layer 33 connecting the upper layer 31 and the lower layer 32.

The upper edge 31a is connected to the inner circle of the groove wall of the groove 31b and extends. The mounting plate 2 is arranged in the groove 31b, and the upper edge 31a and the groove 31b elastically fit on the mounting plate 2. The bottom of the groove 31b is higher than the intermediate layer 33, which is convenient for the mounting plate 2 to be placed in contact with the bottom of the groove 31b.

[0038] In this embodiment, a gap groove 34 is provided between the upper layer 31 and the lower layer 32. The gap groove 34 is located on the outer ring of the middle layer 33 and communicates with the outer wall surface of the rubber sucker 3. Moreover, a plurality of protruding and annularly closed convex feet 35 are provided on the lower end surface of the lower layer 32, and an air cavity 36 is formed inside the inner ring of the convex feet 35. Generally, the bottom of the rubber sucker 3 is flat, and when air is pumped out, the bottom will also bulge upward to form an air cavity.

[0039] Preferably, the length of the convex feet 35 located on the outer ring is greater than the length of the convex feet 35 located on the inner ring, that is, the lower end surfaces of adjacent convex feet 35 are inclined downward from the inside to the outside.

[0040] Such as Figure 2 、 Figure 4 and Figure 5 As shown, an air guide pipe 37 is provided on the rubber sucker 3. The air guide pipe 37 is arranged at the bottom of the middle layer 33 or the embedding groove 31b, and the pipe hole of the air guide pipe 37 is penetrated. The pipe hole communicates with the air cavity 36 located below the middle layer 33. A through hole one 13 is provided on the fixed disk 1b of the main frame 1, and a through hole two 21 is provided on the mounting disk 2. The air guide pipe 37 sequentially passes through the through hole two 21 and the through hole one 13 and exposes the fixed disk 1b.

[0041] In this embodiment, columns 14 are provided at both ends of the handle. The columns 14 and the fixed disk 1b can also be fixedly connected by screws two (screws two are not shown in the attached drawings of the specification), and the screws two are installed from bottom to top. An installation groove 15 is provided on one column 14 of the handle 1a. The through hole one 13 communicates with the installation groove 15. The installation groove 15 is provided with an upper opening or a side opening, and the air guide pipe 37 is inserted into the installation groove 15 until the end. Moreover, the air pump is inserted into the installation groove 15 for installation and is connected to the air guide pipe.
