Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, in particular to a suction cup connection structure for a plate lifter. Background Art

[0002] In the tile laying industry, suction cups are commonly used tools. Workers can use suction cups to absorb tiles for long-distance transportation and careful handling. The tiles used in different scenarios are of different sizes. When a single suction cup cannot lift some larger tiles, workers will connect multiple suction cups to a plate lifter, and multiple workers use the plate lifter to carry the larger tiles together. Currently, the suction cup and the plate lifter are usually connected by a bending piece and tightened with several screws at both ends of the bending piece. This method requires each suction cup to be tightened with the bending piece one by one before and after each work, or the screws must be completely separated from the bending piece one by one before they can be separated. Repetitive disassembly and tightening of screws affects the work efficiency of workers. Therefore, there is a need for a suction cup clamping structure that can quickly separate the suction cup and the plate lifter, does not require loosening each screw, and can still be stably connected to the suction cup. Summary of the Invention

[0003] The utility model aims to provide a suction cup connection structure which has a simple structure, can quickly separate the suction cup and the plate lifter, does not need to loosen each screw and can still be stably connected to the suction cup for use.

[0008] Tightening the fixing nut can cause it to move upward along the second articulated screw until it abuts against the lower surface of the lower splint. At this time, the second articulated screw is confined in the side opening and cannot disengage. Loosening the fixing nut can cause it to disengage from the abutment against the lower surface of the lower splint. At this time, the second articulated screw can be rotated outward from the opening of the side opening and disengage, thereby forming a disengagement space between the second articulated screw and the lower splint, and the suction cup grip rod can be moved out of the disengagement space.

[0009] Furthermore, a second rotating rod is provided in the second rotating part, and the second rotating rod passes through the second movable screw. The second movable screw rotates around the second rotating rod, driving the fixing nut to rotate out of contact with the lower surface of the upper connecting plate. At this time, the second movable screw can be rotated out of the side opening through the second rotating rod.

[0010] Furthermore, the number of the first movable screws is two, and a first rotating rod is also provided in the first rotating part. The first rotating rod passes through the first movable screw, and the first movable screw rotates around the first rotating rod. When the second movable screw rotates to disengage from the side opening, the lower splint rotates around the first rotating rod through the first movable screw and disengages from the gripping rod on the suction cup.

[0011] Furthermore, a through hole is provided on the lower clamping plate, and the lower end of the first movable screw passes through the through hole, and the lower end of the first movable screw is threadedly connected to a flange nut.

[0012] Furthermore, the upper surface of the upper connecting plate is also provided with a plurality of placement grooves, rotation grooves and installation grooves. The first rotating rod and the second rotating rod can be placed in the rotation groove. The installation groove can be provided with fixing screws. The upper connecting plate is also provided with a suction cup clamp seat, and the suction cup clamp seat is fixedly connected to the upper connecting plate through fixing screws and the installation groove.

[0013] Furthermore, the lower surface of the upper connecting plate is formed with an upper clamping portion adapted to the grip rod, and the upper surface of the lower clamping plate is formed with a lower clamping portion adapted to the grip rod. The upper clamping portion and the lower clamping portion are formed into the clamping area, and the upper clamping portion and the lower clamping portion are both arc-shaped.

[0014] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0015] The invention relates to a suction cup connection structure for a plate lifter, which is suitable for use with a suction cup. In order to solve the problem that the suction cup currently on the market needs to be fixed with many screws when used in conjunction with the plate lifter, so as to prevent the suction cup from being separated from the tool and causing the object adsorbed by the suction cup to fall, when carrying larger tiles, it is necessary to equip multiple suction cups so as to adsorb the object more stably. This connection method causes each suction cup to be tightened with several screws using a screwdriver. In particular, the connection part between the suction cup and the tool is currently connected by a bending piece, which is not stable enough. When disassembling, each screw needs to be completely separated from the connection part before the connecting part can be separated from the suction cup. The utility model clamps the gripping rod on the suction cup by the upper connecting plate and the lower clamping plate, so that the suction cup and the tool can be stably connected and will not be easily separated. When clamping the gripping rod, it is only necessary to clamp the gripping rod on the suction cup by the upper connecting plate and the lower clamping plate, and then rotate the fixing nut to make it move upward along the thread. When the upper surface of the fixing nut abuts against the lower surface of the upper connecting plate, the fixing nut is tightened by the user and the lower surface of the upper connecting plate is formed. When the second screw is rotated out of the side opening, the lower splint will be rotated by the first screw due to gravity and the separation space will be gradually increased. At this time, the upper surface of the gripping rod on the suction cup will be separated from the upper connecting plate, and the lower surface of the gripping rod on the suction cup will be separated from the lower splint, and the gripping rod on the suction cup can be moved out of the separation space. Moreover, since the fixing nut of the utility model only needs to be rotated one or two times, after leaving the gripping rod, the fixing nut does not need to be removed and stored separately. The clamping of the utility model can not only better and more stably clamp the gripping rod on the suction cup, but also the speed of clamping and disassembly is very fast.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with specific embodiments:

[0029] A suction cup connection structure for a plate lifter, comprising an upper connecting plate 2 connected to the plate lifter and a lower clamping plate 3 connected to a suction cup gripping rod, wherein a clamping area is formed between the upper connecting plate 2 and the lower clamping plate 3, and the upper connecting plate 2 is provided with a first rotating portion 4 and a second rotating portion 5 on both sides of the clamping area;

[0030] A first movable screw 6 is provided on the first rotating part 4. The upper end of the first movable screw 6 is rotatably connected to the first rotating part 4, and the lower end thereof is fixedly connected to one side of the lower clamping plate 3. The other side of the lower clamping plate 3 is provided with a side opening 8.

[0031] A second movable screw 7 is provided on the second rotating portion 5. The upper end of the second movable screw 7 is rotatably connected to the second rotating portion 5, and the lower end of the second movable screw 7 is detachably connected to the side opening 8 on the lower clamping plate 3. The lower end of the second movable screw 7 can be rotated around the second rotating portion 5 so that it can enter or move away from the side opening 8 laterally from the side of the lower clamping plate 3. The lower end of the second movable screw 7 is threadedly connected to a fixing nut 9.

[0032] Tightening the fixing nut 9 can cause it to move upward along the second articulated screw 7 until it abuts against the lower surface of the lower splint 3. At this time, the second articulated screw 7 is confined in the side opening 8 and cannot disengage; loosening the fixing nut 9 can cause it to disengage from the abutment against the lower surface of the lower splint 3. At this time, the second articulated screw 7 can be rotated outward from the opening of the side opening 8 and disengage, thereby forming a disengagement space 20 between the second articulated screw 7 and the lower splint 3, and the suction cup grip rod can be moved out of the disengagement space 20.

[0033] The utility model discloses a suction cup connection structure for a plate lifter, which is suitable for use with a suction cup. In order to solve the problem that the suction cup and the plate lifter currently on the market need to be fixed with many screws when used together, so as to prevent the suction cup from being separated from the tool and causing the objects adsorbed by the suction cup to fall off, when carrying larger tiles, it is also necessary to equip multiple suction cups so as to more stably adsorb the objects. This connection method causes each suction cup to be tightened with several screws by a screwdriver, especially the current connection part between the suction cup and the tool is connected by a bent piece, which is not stable enough and is difficult to disassemble. When the tool is in a state of being disconnected from the tool, it is necessary to completely separate each screw from the connected part in order to separate the connector from the suction cup. The utility model clamps the gripping rod on the suction cup by the upper connecting plate 2 and the lower clamping plate 3, so that the suction cup and the tool can be stably connected and will not be easily separated. To clamp the gripping rod, it is only necessary to clamp the gripping rod on the suction cup by the upper connecting plate 2 and the lower clamping plate 3, and then rotate the fixing nut 9 to move it upward along the thread. When the upper surface of the fixing nut 9 abuts against the lower surface of the upper connecting plate 2, the fixing nut 9 is tightly abutted against the lower surface of the upper connecting plate 2 by the abutting force generated by the fixing nut 9 after being tightened by the user. The second movable screw 7 is fixed so that it cannot move and fix the second movable screw 7. The second movable screw 7 cannot move, and the way to open the utility model is also very simple. It only needs to rotate the fixing nut 9 one or two turns to separate the upper surface of the fixing nut 9 from the lower surface of the upper connecting plate 2, and release the interaction force generated when the fixing nut 9 abuts against the lower surface of the upper connecting plate 2. At this time, the second movable screw 7 can drive the fixing nut 9 to move outward from the side opening 8. At this time, a separation space 20 will be formed between the second movable screw 7 and the lower splint 3. When the second movable screw 7 is rotated to separate When the side opening 8 is opened, the lower splint 3 will rotate through the first movable screw 6 due to gravity and gradually increase the disengagement space 20. At this time, the upper surface of the gripping rod on the suction cup will be separated from the upper connecting plate 2, and the lower surface of the gripping rod on the suction cup will be separated from the lower splint 3. The gripping rod on the suction cup can be moved out of the disengagement space 20. In addition, the fixing nut 9 of the utility model only needs to be rotated one or two times. After leaving the gripping rod, the fixing nut 9 does not need to be removed and stored separately. The clamping of the utility model can not only better and more stably clamp the gripping rod on the suction cup, but also the clamping and disassembly speeds are very fast.

At this time, the second movable screw 7 can be rotated out of the side opening 8 by the second rotating rod 10. The utility model makes the second movable screw 7 rotate smoothly by rotatably connecting the upper end of the second movable screw 7 with the second rotating rod 10. The movable screws of the utility model are all movable screws commonly used by workers on the market.
