Description

Technical Field

[0001] The utility model relates to a plate lifter, in particular to a plate lifter with adjustable angle. Background Art

[0002] A plate lifter is a tool for carrying large-sized plates such as large ceramic tiles. As shown in the patent 202222991335.7, the existing plate lifter includes a plate-lifting frame in a grid structure. A plurality of vacuum suction cups are spaced apart at the bottom of the plate-lifting frame, and the vacuum suction cups are fixed to the plate-lifting frame by screws through a suction cup mounting frame; during use, the vacuum suction cups respectively adsorb the four peripheral end corners of the plate, and then an operator carries the plate through the plate-lifting frame.

[0003] However, the defect of this plate lifter is that, on the one hand, the screw fixation method will cause the relative position of the suction cup mounting frame on the plate-lifting frame to be non-adjustable; on this basis, even if the vacuum suction cups of the plate lifter in the above patent are connected to a telescopic rod structure, so that the vacuum suction cups can move horizontally with the telescopic movement of the rod, the positions of the vacuum suction cups on each rod still cannot be adjusted individually, thus reducing the flexibility of adjusting the distribution position of the vacuum suction cups.

[0004] On the other hand, this plate lifter realizes the connection between the first lifting rod and the second lifting rod through a tenon groove structure, but this connection method will correspondingly limit the installation angle between the first lifting rod and the second lifting rod, that is, the first lifting rod and the second lifting rod can only be in a relatively perpendicular state, or form any fixed connection angle; furthermore, the vacuum suction cups on different first lifting rods can only be adjusted within a specific length range, further reducing the flexibility of adjusting the distribution position of the vacuum suction cups.

[0005] Therefore, the existing plate lifter has the problem of poor flexibility in adjusting the position of the vacuum suction cups. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a plate lifter with adjustable angle. It can improve the flexibility of adjusting the position of the vacuum suction cups.

[0007] The technical solution of the utility model: A plate lifter with adjustable angle includes a plate-lifting frame formed by connecting a first bracket and a second bracket. The outside of the first bracket is connected with a suction cup mounting frame through a first chute. The suction cup mounting frame is fixedly connected to the first chute through a first positioning component. A vacuum suction cup is detachably connected to the suction cup mounting frame; the first positioning component includes a slider snap-fitted in the first chute. A locking pin is connected to the outside of the slider. The end of the locking pin extends to the outside of the first chute and is rotatably connected with a pressing rod, and the pressing rod is used to drive the locking pin to be pulled outwards after rotation.

[0008] In the aforementioned adjustable-angle lifting plate device, the end of the locking pin is rotatably connected to a pressure rod via a connecting shaft. An extrusion portion is provided on the pressure rod on one side of the connecting shaft, and the extrusion portion is used to move toward the slider as the pressure rod rotates.

[0009] In the aforementioned adjustable-angle lifting plate device, a first limit screw is provided on the suction cup mounting bracket on one side of the first positioning assembly. The end of the first limit screw extends into the first chute and is threadedly connected to the slider.

[0010] In the aforementioned adjustable-angle lifting plate device, a second chute is provided on the outer side of the second bracket. The first bracket and the second bracket are connected to each other via a transfer plate. One side of the transfer plate is fixedly connected to the first chute via a first positioning assembly, and the other side of the transfer plate is fixedly connected to the second chute via a second positioning assembly. The structure of the second positioning assembly is the same as that of the first positioning assembly.

[0011] In the aforementioned adjustable-angle lifting plate device, a second limit screw is provided on the transfer plate on one side of the second positioning assembly. The end of the second limit screw extends into the second chute and is threadedly connected to the slider.

[0012] In the aforementioned adjustable-angle lifting plate device, the first bracket includes two parallel rod bodies. A first chute is provided on the outer portion of each rod body. The number of the vacuum suction cups is multiple and they are respectively installed on the first chutes of the two rod bodies. The two rod bodies are connected to each other via a third positioning assembly.

[0013] In the aforementioned adjustable-angle lifting plate device, the structure of the third positioning assembly is the same as that of the first positioning assembly. The slider of the third positioning assembly is located in the first chute of one of the rod bodies, and the locking pin of the third positioning assembly passes through the other rod body and is connected to the pressure rod.

[0014] In the aforementioned adjustable-angle lifting plate device, a flexible gasket sleeved on the outside of the locking pin is provided on the pressure rod near the slider.

[0015] In the aforementioned adjustable-angle lifting plate device, handles are connected to both ends of the first bracket via a fourth positioning assembly. The structure of the fourth positioning assembly is the same as that of the first positioning assembly.

[0016] Compared with the prior art, the present utility model has the following characteristics:

[0017] (1) By defining the structures of the first bracket and the first positioning assembly, the present utility model enables the slider to slide arbitrarily and be tightly pressed and fixed in the first chute by rotating the pressure rod. On this basis, the operator can quickly move and fix the lateral position of the vacuum suction cup on the first clamping member, thereby realizing the individual adjustment of each vacuum suction cup;

[0018] (2) By connecting the first bracket and the second bracket to each other through the cooperation of the adapter plate and the second positioning component, the installation position of the second positioning component on the adapter plate can be arbitrarily rotated and displaced along with the first bracket, and after the first bracket rotates into place, it is fixed by pressing in the same manner; under the above cooperation, the inclination angle of each first bracket and the spacing distance between adjacent first brackets can be adjusted separately as needed, and the sliding connection between the second chute and the second positioning component enables the second bracket to connect and fix the first brackets at different positions and inclination angles, further improving the flexibility of the vacuum suction cup during position adjustment;

[0019] (3) Through the structural limitation of the first bracket and the setting of the third positioning component, the first bracket can expand and contract the rod body during adjustment, so that the length dimension of the lifting plate frame can be adjusted according to the size of the plate, thereby increasing the position adjustment range of the vacuum suction cup and the use effect of the present utility model; through the structural limitation of the first bracket and the setting of the fourth positioning component, the operator can operate the pressure rod on the fourth positioning component to quickly adjust and fix the lateral position of the handle on the first bracket, further improving the operation flexibility of the present utility model;

[0020] (4) Since the above functions of the present utility model are all realized by the first positioning component, the second positioning component, the third positioning component and the fourth positioning component with the same structure, it can also improve the generality between different components and facilitate the stock preparation, production and assembly of the manufacturer;

[0021] Therefore, the present utility model can improve the flexibility of position adjustment of the vacuum suction cup. BRIEF DESCRIPTION OF THE DRAWINGS

The number of the first support 1 and the second support 2 is multiple and they are connected in a cross shape. The outside of the first support 1 is connected with a suction cup mounting bracket 4 through a first sliding groove 3. The suction cup mounting bracket 4 is fixedly connected with the first sliding groove 3 through a first positioning component 5. A vacuum suction cup 6 is detachably connected to the suction cup mounting bracket 4; the first positioning component 5 includes a slider 7 buckled in the first sliding groove 3. A locking pin 8 is connected to the outside of the slider 7. The end of the locking pin 8 extends to the outside of the first sliding groove 3 and is rotatably connected with a pressing rod 9. The pressing rod 9 is used to drive the locking pin 8 to be pulled outwards after rotation.

[0031] The end of the locking pin 8 is rotatably connected with the pressing rod 9 through a connecting shaft 10. An extrusion part 11 is arranged on the pressing rod 9 on one side of the connecting shaft 10. The extrusion part 11 is used to move towards the slider 7 along with the rotation of the pressing rod 9 and cooperate with the slider 7 to achieve tight pressing and fixing.

[0032] A first limit screw 12 is arranged on the suction cup mounting bracket 4 on one side of the first positioning component 5. The end of the first limit screw 12 extends into the first sliding groove 3 and is threadedly connected with the slider 7.

[0033] A second sliding groove 13 is arranged on the outside of the second support 2. The first support 1 and the second support 2 are connected to each other through an L-shaped adapter plate 14. One side of the adapter plate 14 is fixedly connected with the first sliding groove 3 through a first positioning component 5. The other side of the adapter plate 14 is fixedly connected with the second sliding groove 13 through a second positioning component 15. The structure of the second positioning component 15 is the same as that of the first positioning component 5. The slider 7 of the second positioning component 15 is buckled in the second sliding groove 13.

[0034] The cross-sectional shapes of the first sliding groove 3 and the second sliding groove 13 are both T-shaped. The number of the first sliding grooves 3 is multiple and they are annularly distributed around the first support 1. The number of the second sliding grooves 13 is multiple and they are annularly distributed around the first support 1.

[0035] A second limit screw 16 is provided on the adapter plate 14 on one side of the second positioning component 15. The end of the second limit screw 16 extends into the second chute 13 and is threadedly connected to the slider 7.

[0036] The first bracket 1 includes two parallel rod bodies 101. A plurality of first chutes 3 are distributed around each rod body 101. The number of the vacuum suction cups 6 is multiple and they are respectively installed on the first chutes 3 of the two rod bodies 101. The two rod bodies 101 are interconnected by a third positioning component 17.

[0037] The structure of the third positioning component 17 is the same as that of the first positioning component 5. The number of the third positioning components 17 on each first bracket 1 is two and they are respectively arranged at the ends of the two rod bodies 101. The slider 7 of the third positioning component 17 is located in the first chute 3 of one of the rod bodies 101. The locking pin 8 of the third positioning component 17 passes through the other rod body 101 and is connected to the pressure rod 9. A round hole for the locking pin 8 to pass through is provided on this rod body 101.

[0038] A flexible gasket 18 sleeved outside the locking pin 8 is provided on the pressure rod 9 on the side close to the slider 7. The flexible gasket 18 can be selected as a rubber gasket.

[0039] Handles 20 are connected to both ends of the first bracket 1 through a fourth positioning component 19. The structure of the fourth positioning component 19 is the same as that of the first positioning component 5.

[0040] The working principle of the present utility model: Through the structural definition of the first positioning component 5, the second positioning component 15, the third positioning component 17 and the fourth positioning component 19, when operating, the pressure rod 9 can be rotated to a state perpendicular to the slider 7, so that the locking pin 8 axially moves towards the slider 7 along with the rotation, that is, the extrusion limit on the slider 7 is released. In this state, the operator can adjust the lateral position of the slider 7 in the first chute 3 or the second chute 13. After the slider 7 is positioned, the operator rotates the pressure rod 9 to a state parallel to the slider 7. During the rotation of the pressure rod 9, the locking pin 8 will be pulled outwards, and accordingly the extrusion part 11 will be driven to move towards the slider 7, so that the extrusion part 11 overcomes the elastic force of the flexible gasket 18 and squeezes the inner side after rotation, thereby using the cooperation of the pressure rod 9 and the extrusion part 11 to squeeze and fix the first bracket 1 or the second bracket 2.

[0041] Based on this structure, the utility model can adjust the lateral position of the vacuum suction cup 6 on the first bracket 1 through the setting of the first positioning component 5. Through the cooperative setting of the first positioning component 5, the second positioning component 15 and the adapter plate 14, the adapter plate 14 can rotate with the angle between the second bracket 2 and the first bracket 1 during installation, that is, to achieve stable connection between the first bracket 1 and the second bracket 2 at any angle, and enable the operator to adjust the interval position between adjacent first brackets 1 accordingly. Through the cooperative setting of the rod body 101 and the third positioning component 17, the telescopic and fixing of the first bracket 1 can also be realized, thereby increasing the adjustment range of the vacuum suction cup 6 on the first bracket 1. Through the cooperative setting of the rod body 101 and the fourth positioning component 19, the operator can adjust the lateral position of the handle 20 on the first bracket 1, thus facilitating the handling operation of the lifting plate device.
