[0030] like Figure 1-2 As shown, a building panel attaching device includes a control ring 2, a driving rod 3 is rotatably connected to the middle part of the control ring 2, a positioning rod 4 is symmetrically connected to the side end surface of the control ring 2, a holding rod 1 is movably provided at one end of the positioning rod 4 away from the control ring 2, an adsorption mechanism 7 for negative pressure adsorption of the decorative panel 5 is fixedly connected to the lower end of the control ring 2, a movable sealing cavity 9 is provided inside the adsorption mechanism 7, a piston plate 10 is slidably connected inside the movable sealing cavity 9, the driving rod 3 passes through the control ring 2 and extends to the inside of the movable sealing cavity 9 and is driven and connected to the piston plate 10, and a sealing ring 13 is embedded at the bottom of the adsorption mechanism 7.

[0031] When in use, the piston plate 10 is driven to slide inside the movable sealing chamber 9 by rotating the driving rod 3, so that negative pressure is generated between the piston plate 10 and the decorative panel 5, and then the decorative panel 5 is fixed and limited, and the decorative panel 5 can be lifted or moved by holding the holding rod 1 or the positioning rod 4, so that the decorative panel 5 can be easily attached after being fixed by the adsorption mechanism 7, which greatly improves the convenience of the device, and further, a sealing ring 13 is embedded in the bottom of the adsorption mechanism 7, and the sealing ring 13 can effectively improve the sealing between the adsorption mechanism 7 and the decorative panel 5, thereby improving the adsorption and fixing effect of the adsorption mechanism 7 on the decorative panel 5. Example

[0032] Based on the first embodiment, Figure 1-5 As shown, the piston plate 10 is rotatably sleeved on the outer end surface of the driving rod 3, and a driving ring 12 threadedly connected to the driving rod 3 is provided in the middle of the piston plate 10.

[0033] like Figure 1-5 As shown, the outer end surface of the piston plate 10 is fixedly connected to the first limiting sliding rod 22 , and the inner wall of the movable sealing chamber 9 is provided with a groove matched with the first limiting sliding rod 22 .

[0034] When in use, a threaded groove is provided at the end of the driving rod 3, and the driving rod 3 is rotated to mesh with the driving ring 12 by means of the threaded groove. At the same time, the piston plate 10 is connected to the sliding of the movable sealing chamber 9 through the first limiting sliding rod 22, so that the piston plate 10 can only slide in the vertical direction inside the movable sealing chamber 9, and then the driving ring 12 can be driven to move up and down by the rotation of the driving rod 3, and the piston plate 10 is driven to move inside the movable sealing chamber 9 by the movement of the driving ring 12, and the outer side of the piston plate 10 is tightly fitted with the movable sealing chamber 9. When the adsorption mechanism 7 is fitted with the decorative panel 5, the pressure between the piston plate 10 and the decorative panel 5 is reduced, forming a negative pressure to adsorb and fix the decorative panel 5.

[0035] like Figure 1-7 As shown, a sliding groove 17 is provided on the upper end surface of the piston plate 10, and a sliding plate 19 is slidably connected inside the sliding groove 17, and a limiting groove 21 adapted to the sliding plate 19 is provided on the upper end surface of the drive ring 12, a second limiting slide rod 23 is fixedly connected to the side end surface of the sliding plate 19, and a groove adapted to the second limiting slide rod 23 is provided inside the sliding groove 17.

[0036] like Figure 1-7 As shown, the inner wall of the movable sealing chamber 9 is fixedly connected with a driving rod 15, the driving rod 15 is arranged at an angle, a bevel groove 20 adapted to the driving rod 15 is opened inside the sliding plate 19, a fixed groove 16 adapted to the sliding plate 19 is opened on the inner wall of the movable sealing chamber 9, and an adapting groove 18 adapted to the driving rod 15 is opened inside the piston plate 10.

[0037] When in use, the piston plate 10 and the drive ring 12 are pinned together by the sliding plate 19, so that the drive ring 12 cannot rotate. As the drive ring 12 drives the piston plate 10 to move upward continuously, when the negative pressure between the piston plate 10 and the decorative panel 5 is large enough, a drive rod 15 is provided to avoid damage to the device and the decorative panel 5. As the piston plate 10 moves upward continuously, the drive rod 15 gradually fits with the inclined groove 20. As the piston plate 10 continues to move upward, the drive rod 15 moves to the inside of the adapter groove 18, and the sliding plate 19 is driven by the action of the inclined surface on the piston plate 10. The surface moves laterally, thereby causing the sliding plate 19 to disengage from the limiting groove 21. At this time, the driving ring 12 can rotate synchronously with the driving rod 3, and further, as the sliding plate 19 moves laterally, the end of the sliding plate 19 away from the limiting groove 21 slides into the interior of the fixing groove 16. When the pin connection between the driving ring 12 and the piston plate 10 is disengaged, the piston plate 10 will move downward under the action of negative pressure, and then the sliding plate 19 will be fixed by the fixing groove 16, thereby avoiding the movement of the piston plate 10 to provide a stable pressure between the decorative panel 5 and the piston plate 10.

[0038] like Figure 1-4As shown in 8, the sealing ring 13 includes a fixing plate 29, a spring cavity 30, a pressing portion 31 and a flexible sealing layer 32. The spring cavity 30 is opened at the bottom of the adsorption mechanism 7, the fixing plate 29 is fixedly connected to the top of the inner wall of the spring cavity 30, the pressing portion 31 is elastically connected to the inside of the spring cavity 30, and the flexible sealing layer 32 is fixedly connected to the lower end surface of the pressing portion 31.

[0039] like Figure 1-4 As shown in FIG. 8 , an air hole 28 is opened in the middle of the fixed plate 29 , and a connecting groove 14 is provided inside the adsorption mechanism 7 . One end of the connecting groove 14 is connected to the spring chamber 30 through the air hole 28 , and the end of the connecting groove 14 away from the spring chamber 30 is connected to the upper part of the movable sealing chamber 9 .

[0040] like Figure 1-4 As shown in FIG. 8 , a pressure relief hole 6 is provided on the outer end surface of the adsorption mechanism 7 . The pressure relief hole 6 is connected to the spring cavity 30 , and the horizontal position of the pressure relief hole 6 is lower than the upper end surface of the pressing portion 31 .

[0041] When in use, the pressing part 31 presses the flexible sealing layer 32 through elastic force, and the flexible sealing layer 32 can be distributed in an annular shape, thereby sealing the area between the adsorption mechanism 7 and the decorative panel 5, thereby improving the sealing effect of the decorative panel 5 and the piston plate 10, and further, the interior of the movable sealing chamber 9 is sealed, and the connecting groove 14 is provided on the inner wall of the movable sealing chamber 9 to communicate with the spring chamber 30. As the piston plate 10 moves upward, the pressure on the top of the movable sealing chamber 9 increases, thereby entering the spring chamber 30 through the connecting groove 14 and then pressing, and the pressing part 31 moves further downward, thereby maximizing its sealing effect, and further when the spring chamber The internal pressure of 30 continues to increase, and the pressing part 31 compresses the flexible sealing layer 32 to a limit value. At this time, as the pressing part 31 continues to move downward, the pressure relief hole 6 is connected with the spring chamber 30, thereby relieving the pressure on the top of the movable sealing chamber 9. As the pressure is relieved, the pressing part 31 will return to its original position, so that there is a dynamically balanced positive pressure inside the spring chamber 30, which presses the pressing part 31, and then the upward movement of the piston plate 10 further improves the sealing effect of the flexible sealing layer 32, effectively avoiding pressure relief and air leakage during the clamping process, which may cause the decorative panel 5 to fall off, causing certain loss of life and property.

[0042] like Figure 1-4 As shown in Figures 9-10, the interior of the positioning rod 4 is rotatably connected to a rotating rod 24, and a second bevel gear 26 is provided at one end of the rotating rod 24 that is in contact with the driving rod 3, and a first bevel gear 25 meshing with the second bevel gear 26 is provided on the outer side of the side end surface of the driving rod 3.

[0043] like Figure 1-4 As shown in FIGS. 9-10 , one end of the rotating rod 24 away from the second bevel gear 26 is threadedly engaged with the holding rod 1 , and an anti-skid layer 27 is embedded in the outer end of the holding rod 1 .

[0044] When in use, since the holding area of ​​the existing adsorption device is small, it is difficult to hold when encountering a large-area decorative panel 5. Using multiple groups of adsorption mechanisms 7 to adsorb the four corners also has the problem of being difficult to hold. At the same time, due to the adsorption force between the multiple groups of adsorption mechanisms 7 and the holding angle and other problems, it is very easy to cause falling off, which poses a great safety hazard. The device drives the first bevel gear 25 by rotating the driving rod 3, and then drives the rotation of the rotating rod 24 through the second bevel gear 26. Through the threaded engagement of the rotating rod 24 and the holding rod 1, the holding rod 1 can be driven to extend to both sides until it is equal to or greater than the width of the decorative panel 5. Since the piston plate 10 moves to a certain height, the driving ring 12 can fall off the piston plate 10 after the pressure between the decorative panel 5 and the piston plate 10 is stable. At this time, the driving rod 3 can be rotated at will, so that the telescopic width of the holding rod 1 will not be limited by the displacement of the piston plate 10, and can be freely adjusted as needed. The holding rod 1 and the positioning rod 4 can be limited by a limit rod to prevent the holding rod 1 from rotating synchronously with the rotating rod 24.

[0045] Furthermore, a connecting cavity is provided inside the driving rod 3, in which an elastic rod 8 is provided, and a sealing block 11 is fixedly connected to the bottom of the elastic rod 8. The sealing block 11 seals the connecting cavity inside 3 through the elastic force of the elastic rod 8. After the attachment is completed, the sealing block 11 can be moved downward to restore the pressure between the decorative panel 5 and the piston plate 10, so that the device can be separated from the decorative panel 5.

[0046] Working principle: By rotating the driving rod 3, the piston plate 10 is driven to slide inside the movable sealing chamber 9, so that negative pressure is generated between the piston plate 10 and the decorative panel 5, and then the decorative panel 5 is fixed and limited. The decorative panel 5 can be lifted or moved by holding the holding rod 1 or the positioning rod 4, so that the decorative panel 5 can be easily attached after being fixed by the adsorption mechanism 7, which greatly improves the convenience of the device. Furthermore, a sealing ring 13 is embedded at the bottom of the adsorption mechanism 7. The sealing ring 13 can effectively improve the sealing between the adsorption mechanism 7 and the decorative panel 5, thereby improving the adsorption and fixing effect of the adsorption mechanism 7 on the decorative panel 5. A threaded groove is provided at the end of the driving rod 3. By rotating the driving rod 3, with the help of the threaded groove and the driving ring 12 is meshed, and at the same time, the piston plate 10 is connected with the sliding of the movable sealing chamber 9 through the first limiting sliding rod 22, so that the piston plate 10 can only slide in the vertical direction inside the movable sealing chamber 9, and then the driving ring 12 can be driven to move up and down by the rotation of the driving rod 3, and the piston plate 10 is driven to move inside the movable sealing chamber 9 through the movement of the driving ring 12, and the outer side of the piston plate 10 is tightly fitted with the movable sealing chamber 9. When the adsorption mechanism 7 is fitted with the decorative panel 5, the pressure between the piston plate 10 and the decorative panel 5 is reduced, forming a negative pressure to adsorb and fix the decorative panel 5, and the piston plate 10 and the driving ring 12 are pinned together by the sliding plate 19, so that the driving ring 12 cannot rotate. Continuously move upward, when the negative pressure between the piston plate 10 and the decorative panel 5 is large enough, in order to avoid damage to the device and the decorative panel 5, a driving rod 15 is provided. As the piston plate 10 continues to move upward, the driving rod 15 gradually fits with the inclined groove 20. As the piston plate 10 continues to move upward, the driving rod 15 moves to the inside of the adapter groove 18. Under the action of the inclined surface, the sliding plate 19 will be driven to move laterally on the surface of the piston plate 10, thereby causing the sliding plate 19 to disengage from the limiting groove 21. At this time, the driving ring 12 can rotate synchronously with the driving rod 3, and further, at this time, as the sliding plate 19 moves laterally, the end of the sliding plate 19 away from the limiting groove 21 slides into the inside of the fixed groove 16. When the pin connection between the driving ring 12 and the piston plate 10 is disengaged, under the action of negative pressure The lower piston plate 10 will move downward, and then fix the sliding plate 19 through the fixing groove 16, so as to avoid the movement of the piston plate 10, so as to provide stable pressure between the decorative panel 5 and the piston plate 10, and the pressing part 31 presses the flexible sealing layer 32 through elastic force, and the flexible sealing layer 32 can be distributed in an annular shape, so as to seal the area between the adsorption mechanism 7 and the decorative panel 5, so as to improve the sealing effect between the decorative panel 5 and the piston plate 10, and further, the movable sealing chamber 9 is sealed inside, and is connected with the spring chamber 30 by providing a connecting groove 14 on the inner wall of the movable sealing chamber 9. As the piston plate 10 moves upward, the pressure on the top of the movable sealing chamber 9 increases, so as to enter the spring chamber 30 through the connecting groove 14 and then press, and the pressing part 31 moves further downward, so as to maximize its sealing effect.When the pressure in the spring cavity 30 continues to increase and the pressing part 31 compresses the flexible sealing layer 32 to a limit value, the pressure relief hole 6 is connected to the spring cavity 30 as the pressing part 31 moves downward continuously, thereby relieving the pressure on the top of the movable sealing cavity 9. As the pressure is relieved, the pressing part 31 will return to its original position, so that there is a positive pressure in dynamic balance inside the spring cavity 30, pressing the pressing part 31, and further improving the sealing effect of the flexible sealing layer 32 with the help of the upward movement of the piston plate 10, effectively avoiding the decorative panel 5 from falling off due to pressure relief and air leakage during the clamping process, causing certain loss of life and property. Since the existing adsorption equipment has a small gripping area, it is difficult to grip a large-area decorative panel 5, and using multiple adsorption mechanisms 7 to adsorb the four corners also has the problem of being difficult to grip. At the same time, due to Problems such as the adsorption force between the multiple adsorption mechanisms 7 and the holding angle can easily lead to falling off, which poses a great safety hazard. In addition, the device drives the first bevel gear 25 by rotating the driving rod 3, and then drives the rotation of the rotating rod 24 through the second bevel gear 26. Through the threaded engagement of the rotating rod 24 and the holding rod 1, the holding rod 1 can be driven to extend to both sides until it is equal to or greater than the width of the decorative panel 5. Since the piston plate 10 moves to a certain height, the driving ring 12 can fall off the piston plate 10 after the pressure between the decorative panel 5 and the piston plate 10 is stable. At this time, the driving rod 3 can be rotated at will, so that the telescopic width of the holding rod 1 will not be limited by the displacement of the piston plate 10, and can be freely adjusted as needed. The holding rod 1 and the positioning rod 4 can be limited by a limit rod to prevent the holding rod 1 from rotating synchronously with the rotating rod 24.
