An adsorption fixture

Abstract

This application discloses an adsorption fixture that can be manually or electrically applied to a surface to be adsorbed. Those skilled in the art can choose to control the fixture manually or electrically as needed. By rotating the handle, the disc body deforms, creating a vacuum between the disc body and the surface to be adsorbed, thus adsorbing the suction cup onto the surface. Alternatively, by rotating the handle, the disc body deforms, allowing external air to enter between the disc body and the surface to be adsorbed, thereby breaking the vacuum and detaching the suction cup from the surface. A control switch is electrically connected to an air pump and a pressure relief valve. The air pump draws air from between the suction cup and the surface to be adsorbed, causing the suction cup to adhere. Each pressure relief valve corresponds to a suction cup; opening the pressure relief valve allows external air to enter between the suction cup and the surface to be adsorbed, causing the suction cup to detach. Thus, the adsorption fixture can be electrically controlled to adhere to the surface to be adsorbed via the control switch.

Description

Technical Field

[0001] This utility model generally relates to the field of building decoration tools, and more particularly to an adsorption tool. Background Technology

[0002] Ceramic tiles are a type of acid- and alkali-resistant building or decorative material made from refractory metal oxides and semi-metal oxides through grinding, mixing, pressing, glazing, and sintering. Their raw materials are mostly clay and quartz sand, which are mixed after being compressed at high temperatures, resulting in a material with high hardness.

[0003] When laying tiles, they need to be moved manually, which is time-consuming and laborious, and there is also the problem of people getting cut while moving tiles by hand. Utility Model Content

[0004] This utility model provides an adsorption fixture, including: a protective shell, a suction cup, an air extraction mechanism, and a control switch.

[0005] Multiple suction cups are arranged in the same direction on the protective shell. Each suction cup includes a fixed cover, a deformable disc body, a pull rod, and a handle. The fixed cover includes a groove, and the disc body is installed at the opening of the groove. A through hole is provided at the bottom of the groove. One end of the pull rod passes through the through hole and is connected to the surface of the disc body facing the bottom of the groove. The other end is hinged to the handle. By rotating the handle, the disc body is deformed, and a vacuum state is formed between the disc body and the surface to be suctioned, or external air can enter to break the vacuum state.

[0006] The air extraction mechanism includes an air pump and a pressure relief valve. The air pump is connected to each of the suction cups through an air connection. The air pump draws air from between the suction cup and the surface to be adsorbed, causing the suction cup to adhere to the surface to be adsorbed. The pressure relief valve corresponds to each suction cup. When the pressure relief valve is opened, external air can enter between the suction cup and the surface to be adsorbed, causing the suction cup to detach from the surface to be adsorbed.

[0007] The control switch is electrically connected to the air pump and the pressure relief valve.

[0008] As one possible implementation, the connecting air path includes a connecting pipe, which is sequentially connected to each of the suction cups.

[0009] In one possible implementation, the connecting tube is connected to the suction cup via a one-way valve, and when the air pump draws air from between the suction cup and the surface to be adsorbed, the air enters the connecting tube through the one-way valve.

[0010] As an alternative implementation, the pressure relief valve is connected to the suction cup.

[0011] As an implementation method, the protective shell is a hollow profile and is linear, including a first accommodating cavity, and each of the suction cups is arranged sequentially in the first accommodating cavity along the length direction of the hollow profile.

[0012] As an implementation method, the first accommodating cavity has a C-shaped cross-section and includes opposing sidewalls, the outer surface of which is provided with scale lines along its length.

[0013] As an alternative implementation, the hollow profile further includes a second accommodating cavity stacked with the first accommodating cavity, the second accommodating cavity having a frame-shaped cross-section, the connecting air passage being disposed within the second accommodating cavity, and the pull rod being located within the second accommodating cavity.

[0014] As an implementation, the first accommodating cavity includes a first bottom wall disposed perpendicular to the side wall, the second accommodating cavity has an isosceles trapezoidal shape, the second accommodating cavity shares the first bottom wall with the first accommodating cavity, the second accommodating cavity includes a second bottom wall disposed opposite to the first bottom wall, and the width of the second bottom wall is smaller than the width of the first bottom wall.

[0015] As one possible implementation, the end of the second bottom wall in the width direction protrudes into a handhold portion along the direction from the first bottom wall to the second bottom wall, and the control switch and the handle are disposed on the surface of the second bottom wall facing away from the second accommodating cavity and located between the two handhold portions.

[0016] As an alternative implementation, the length of the handheld portion is equal to the length of the second bottom wall.

[0017] The above-described adsorption fixture provided in this application can be manually or electrically applied to the surface to be adsorbed. Those skilled in the art can choose to control the fixture manually or electrically according to their needs. By rotating the handle, the disc body deforms, creating a vacuum between the disc body and the surface to be adsorbed, thus adsorbing the suction cup onto the surface. Alternatively, by rotating the handle, the disc body deforms, allowing external air to enter between the disc body and the surface to be adsorbed, thus breaking the vacuum and detaching the suction cup from the surface. The control switch is electrically connected to an air pump and a pressure relief valve. The air pump draws air from between the suction cup and the surface to be adsorbed, causing the suction cup to adhere to the surface. The pressure relief valve corresponds to a specific suction cup; when opened, it allows external air to enter between the suction cup and the surface to be adsorbed, causing the suction cup to detach. Thus, the adsorption fixture can be electrically controlled to adhere to the surface via the control switch. This fixture is simple and convenient to use, improves handling efficiency, and avoids contact between human hands and tiles, thus preventing hand injuries. When tiling, the suction cups allow for easy handling of the tiles, resulting in even gaps between adjacent tiles. Furthermore, the electric installation eliminates the need for manually adjusting the handles of each suction cup, making operation convenient and saving time. Attached Figure Description

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] When laying tiles, they need to be moved manually, which is time-consuming and laborious, and there is also the problem of people getting cut while moving tiles by hand.

[0031] Therefore, in related technologies, adsorption fixtures are used to hold and move tiles. This is simple, convenient, and improves handling efficiency, while avoiding direct contact between human hands and tiles, thus preventing hand injuries. When tiling, the gaps between adjacent tiles need to be uniform. However, adjusting tiles by hand is inconvenient due to the difficulty in holding them, leading to problems with adjustment. Using adsorption fixtures allows for free movement of tiles, ensuring uniform gaps between adjacent tiles.

[0032] It should be noted that, as Figure 1 and Figure 2 As shown, the adsorption fixture includes a protective shell 10 and multiple suction cups 20, which are arranged in the same direction on the protective shell 10. Each suction cup 20 includes a fixing cover 21, a deformable disc body 22, a pull rod 23, and a handle 24. The fixing cover 21 includes a groove, with the disc body 22 installed at the groove opening, and a through hole at the bottom of the groove. One end of the pull rod 23 passes through the through hole and is connected to the surface of the disc body 22 facing the bottom of the groove, while the other end is hinged to the handle 24. By rotating the handle 24, the disc body 22 is deformed, creating a vacuum state between the disc body 22 and the surface to be adsorbed, thus allowing the suction cup 20 to adsorb onto the surface to be adsorbed; or, by rotating the handle 24, the disc body 22 is deformed, allowing external air to enter between the disc body 22 and the surface to be adsorbed, thereby breaking the vacuum state and allowing the suction cup 20 to detach from the surface to be adsorbed.

[0033] When the adsorption fixture adheres to the surface to be adsorbed, the handle 24 of each suction cup 20 needs to be manually adjusted, which is cumbersome and time-consuming. Therefore, the adsorption fixture also includes an air extraction mechanism 30 and a control switch 40. The air extraction mechanism 30 includes an air pump 31 and a pressure relief valve. The air pump 31 is connected to each suction cup 20 via an air circuit. The air pump 31 extracts air between the suction cup 20 and the surface to be adsorbed, causing the suction cup 20 to adhere to the surface. The pressure relief valve corresponds to each suction cup 20. When the pressure relief valve is opened, external air can enter between the suction cup 20 and the surface to be adsorbed, causing the suction cup 20 to detach from the surface. The control switch 40 is electrically connected to the air pump 31 and the pressure relief valve.

[0034] For example, in one specific embodiment, such as Figure 3 As shown, the adsorption fixture has four suction cups 20: a first suction cup 20a, a second suction cup 20b, a third suction cup 20c, and a fourth suction cup 20d. The connecting air path includes a connecting pipe 32, which connects to the four suction cups 20 in sequence. The connecting pipe 32 is connected to each suction cup 20 via a one-way valve 33, and a pressure relief valve is connected to each suction cup 20.

[0035] like Figure 3 As shown, the connecting pipe 32 includes a first sub-connecting pipe 321a, a second sub-connecting pipe 321b, a third sub-connecting pipe 321c, and a fourth sub-connecting pipe 321d. The one-way valve 33 can be a three-way valve body. The first sub-connecting pipe 321a is connected to the air pump 31; the first sub-connecting pipe 321a and the second sub-connecting pipe 321b are connected through the first one-way valve 33a, and the first one-way valve 33a is connected to the first suction cup 20a; the second sub-connecting pipe 321b and the third sub-connecting pipe 321c are connected through the second one-way valve 33b, and the second one-way valve 33b is connected to the second suction cup 20b; the third sub-connecting pipe 321c and the fourth sub-connecting pipe 321d are connected through the third one-way valve 33c, and the third one-way valve 33c is connected to the third suction cup 20c; the fourth sub-connecting pipe 321d and the fourth suction cup 20d are both connected to the fourth one-way valve 33d.

[0036] The control switch 40 is electrically connected to the pressure relief valves corresponding to the four suction cups 20 via an electrical connection wire, and this electrical connection wire is sequentially connected to the four pressure relief valves. The control switch 40 is also electrically connected to the air pump 31 via another electrical connection wire.

[0037] Pressing the control switch 40 activates the air pumps 31 corresponding to each suction cup 20. The air pumps 31 draw air from between the first suction cup 20a and the surface to be suctioned, passing it through the first one-way valve 33a into the first sub-connecting pipe 321a, thus allowing the first suction cup 20a to adhere to the surface. Similarly, the air pumps 31 draw air from between the second suction cup 20b and the surface to be suctioned, passing it through the second one-way valve 33b into the second sub-connecting pipe 321b, and then from the second sub-connecting pipe 321b to the first sub-connecting pipe 321a, thus allowing the second suction cup 20b to adhere to the surface. Air pump 31 draws air from between the third suction cup 20c and the surface to be adsorbed, which then enters the third sub-connecting pipe 321c through the third one-way valve 33c. The air then flows from the third sub-connecting pipe 321c to the first sub-connecting pipe 321a, thus adsorbing the third suction cup 20c onto the surface to be adsorbed. Similarly, air pump 31 draws air from between the fourth suction cup 20d and the surface to be adsorbed, which then enters the fourth sub-connecting pipe 321d through the fourth one-way valve 33d. The air then flows from the fourth sub-connecting pipe 321d to the first sub-connecting pipe 321a, thus adsorbing the fourth suction cup 20d onto the surface to be adsorbed. This process achieves the adsorption of the tooling onto the surface to be adsorbed.

[0038] If the control switch 40 is pressed again, the air pump 31 corresponding to the first suction cup 20a stops working, and at the same time, the pressure relief valve corresponding to the first suction cup 20a operates, allowing external air to enter between the first suction cup 20a and the surface to be adsorbed, causing the first suction cup 20a to detach from the surface; the pressure relief valve corresponding to the second suction cup 20b operates, allowing external air to enter between the second suction cup 20b and the surface to be adsorbed, causing the second suction cup 20b to detach from the surface; the pressure relief valve corresponding to the third suction cup 20c operates, allowing external air to enter between the third suction cup 20c and the surface to be adsorbed, causing the third suction cup 20c to detach from the surface; the pressure relief valve corresponding to the fourth suction cup 20d operates, allowing external air to enter between the fourth suction cup 20d and the surface to be adsorbed, causing the fourth suction cup 20d to detach from the surface. This achieves the detachment of the adsorption fixture from the surface to be adsorbed.

[0039] It is understood that the adsorption fixture provided in this embodiment can be applied to the surface to be adsorbed using both manual and electric methods. Those skilled in the art can choose to control the adsorption fixture manually or electrically according to their needs.

[0040] Of course, it is understood that in another embodiment, the first sub-connecting pipe 321a is connected to the first suction cup 20a through the first one-way valve 33a; the second sub-connecting pipe 321b is connected to the second suction cup 20b through the second one-way valve 33b; the third sub-connecting pipe 321c is connected to the third suction cup 20c through the third one-way valve 33c; and the fourth sub-connecting pipe 321d is connected to the fourth suction cup 20d through the fourth one-way valve 33d.

[0041] As an alternative implementation, the protective shell 10 is a hollow, linear profile, including a first accommodating cavity 11, in which each suction cup 20 is arranged sequentially along the length of the hollow profile. This arrangement reduces the weight of the entire adsorption device, making it easier for operators to use.

[0042] In a specific embodiment, such as Figure 4 or Figure 5 As shown, the protective shell 10 includes a first accommodating cavity 11 and a second accommodating cavity 12 stacked together. The first accommodating cavity 11 has a C-shaped cross-section and includes opposing side walls 111 and a first bottom wall 112 perpendicular to the side walls 111, with the first bottom wall 112 connecting the two side walls 111. The outer surface of the side walls 111 has graduation lines along its length. The smallest unit of the graduation lines can be mm. This allows the adsorption fixture to be a ruler, used to mark lines on the tile for easy cutting by an electric cutter.

[0043] The second receiving cavity 12 has a frame-shaped cross-section. The aforementioned connecting air passage is located within the second receiving cavity 12, and the pull rod 23 is also located within the second receiving cavity 12. The frame shape effectively disperses the load and resists multi-directional forces such as bending, torsion, and shear through the synergistic effect between the components, thereby improving the mechanical properties of the protective shell 10, which helps to stably adhere to the ceramic tile. At the same time, the clever arrangement of the connecting air passage and the pull rod 23 within the second receiving cavity 12 makes full use of the space and contributes to the miniaturization design of the adsorption fixture.

[0044] like Figure 4 or Figure 5 As shown, the shape of the second accommodating cavity 12 may be, but is not limited to, an isosceles trapezoid. The second accommodating cavity 12 shares the first bottom wall 112 with the first accommodating cavity 11. The second accommodating cavity 12 includes a second bottom wall 121 disposed opposite to the first bottom wall 112, and the width of the second bottom wall 121 is smaller than the width of the first bottom wall 112.

[0045] The end of the second bottom wall 121 in the width direction protrudes into a handle portion 13 along the direction from the first bottom wall 112 to the second bottom wall 121. In one embodiment, the length of the handle portion 13 may be equal to the length of the second bottom wall 121; in another embodiment, the length of the handle portion 13 may be less than the length of the second bottom wall 121, and several handle portions 13 are arranged at equal intervals. This allows the operator to grasp the handle portion 13, which helps the operator to grasp the suction tool.

[0046] like Figure 4 or Figure 5 As shown, the control switch 40 and handle 24 are disposed on the surface of the second bottom wall 121 facing away from the second receiving cavity 12, and are located between the two hand grips 13. In this way, the two hand grips 13 can protect the control switch 40 and handle 24 from accidental impact and damage.
