[0004] Although the aforementioned patents solved the problem of not being able to simultaneously adsorb LCD panels and PCB boards by using adjustment plates and fasteners, the fixtures can only adjust the distance between the suction cups and cannot adjust the height and angle of the suction cups, which increases the limitations of the fixtures in use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing fixtures can only adjust the distance between the suction cups and cannot adjust the height and angle of the suction cups, which increases the limitations of the fixtures. Therefore, this invention proposes a suction cup fixture with adjustable height and angle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable suction cup fixture, including a mounting base, a guide frame fixedly connected to one side of the mounting base, an adjustment mechanism provided on one side of the guide frame, the adjustment mechanism including a lead screw, a U-shaped frame and a back plate, one side of the back plate being rotatably connected to the U-shaped frame, one side of the U-shaped frame being fixedly connected to a connecting plate, the lead screw being inserted through the connecting plate, and there are two sets of lead screws, one set of which is rotatably connected to a sponge suction cup one at its end, and the other set of which is rotatably connected to a sponge suction cup two at its end, and one end of the lead screw is rotatably connected to one side of the connecting plate.

[0007] Preferably, a guide ring is provided on one side of the back plate, and a guide rod is rotatably connected inside the guide ring, with one end of the guide rod fixedly connected to the U-shaped frame.

[0008] Preferably, a limiting screw is inserted into one side of the guide rod, and the limiting screw is connected to the back plate by a thread. Both the back plate and the U-shaped frame have positioning holes on one side, and a limiting bolt is inserted into the positioning hole.

[0009] Preferably, an installation rod is inserted between the back plate and the U-shaped frame, the installation rod is rotatably connected to the back plate, and a guide groove is provided on the outer ring surface of the installation rod, with a limit sleeve slidably connected in the guide groove.

[0010] Preferably, the limiting sleeve is penetrated by the end of the mounting rod, and one end of the limiting sleeve is inserted into a limiting hole, which is located on one side of the U-shaped frame.

[0011] Preferably, a side plate is fixedly connected to one side of the back plate, a support frame is slidably connected to one side of the side plate, and one side of the support frame is fixedly connected to the guide frame.

[0012] Preferably, a telescopic rod is fixedly connected to one side of the sponge suction cup, and the other end of the telescopic rod is inserted into the sponge suction cup. A spirit level is also connected to one side of the telescopic rod by bolts.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the ends of the two sets of lead screws are rotatably connected to sponge suction cup one and sponge suction cup two, respectively. The U-shaped frame is rotatably connected to the back plate. When the U-shaped frame is rotated on one side of the back plate, the guide rod moves inside the guide ring. Rotating the limiting screw makes the end of the limiting screw insert into the guide rod. By limiting the U-shaped frame through the guide rod and the limiting bolt, the angle of use of sponge suction cup one and sponge suction cup two can be adjusted. The height of use of sponge suction cup one and sponge suction cup two can be adjusted through the lead screw, thereby reducing the limitations when using the fixture.

[0015] 2. In this utility model, the bubble level is connected to the telescopic rod on one side by bolts, and the limiting sleeve is slidably connected to the mounting rod. The end of the mounting rod passes through the back plate and the U-shaped frame in sequence. The limiting sleeve is moved along the axial direction of the mounting rod, and the end of the limiting sleeve is inserted into the limiting hole. This allows the U-shaped frame to be installed on one side of the back plate, which is convenient for the subsequent disassembly and replacement of the U-shaped frame. The bubble level can be used to detect whether the sponge suction cup and the telescopic rod are on the same horizontal line, which can reduce the positional offset of the sponge suction cup and the telescopic rod.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Refer to Figures 1-5 As shown: A suction cup fixture with adjustable height and angle includes a mounting base 1. A guide frame 2 is fixedly connected to one side of the mounting base 1. An adjustment mechanism is provided on one side of the guide frame 2. The adjustment mechanism includes a lead screw 10, a U-shaped frame 11, and a back plate 12. One side of the back plate 12 is rotatably connected to the U-shaped frame 11. A connecting plate 5 is fixedly connected to one side of the U-shaped frame 11. The lead screw 10 is inserted through the connecting plate 5. There are two sets of lead screws 10. One set of lead screws 10 has a sponge suction cup 6 rotatably connected to its end. The end of the lead screw 10 is rotatably connected to a sponge suction cup 9, and one end of the lead screw 10 is rotatably connected to one side of the connecting plate 5. A guide ring 17 is provided on one side of the back plate 12, and a guide rod 19 is rotatably connected inside the guide ring 17. One end of the guide rod 19 is fixedly connected to the U-shaped frame 11, and a limit screw 13 is inserted into one side of the guide rod 19. The limit screw 13 is threadedly connected to the back plate 12, and a positioning hole is provided on one side of both the back plate 12 and the U-shaped frame 11. A limit bolt 14 is inserted into the positioning hole.

[0025] By using the fixed connection between the U-shaped frame 11 and the connecting plate 5, the sponge suction cup 6 and the sponge suction cup 9 can rotate synchronously when the U-shaped frame 11 rotates, thereby changing the usage direction of the sponge suction cup 6 and the sponge suction cup 9. The sponge suction cup 6 and the sponge suction cup 9 can be used to adsorb different positions of the workpiece. The distance between the connecting plate 5 and the sponge suction cup 6 and the sponge suction cup 9 can be adjusted by the lead screw 10, thereby adjusting the usage height of the sponge suction cup 6 and the sponge suction cup 9. The guide ring 17 can guide the rotation of the guide rod 19 and the U-shaped frame 11. The limit screw 13 can limit the guide rod 19. The double limit using the limit screw 13 and the limit bolt 14 ensures the stable use of the U-shaped frame 11 after the angle is adjusted.

[0026] Example 2: Figures 1-4 As shown, an installation rod 16 is inserted between the back plate 12 and the U-shaped frame 11. The installation rod 16 is rotatably connected to the back plate 12. A guide groove is provided on the outer ring surface of the installation rod 16. A limit sleeve 15 is slidably connected in the guide groove. The limit sleeve 15 is penetrated by the end of the installation rod 16, and one end of the limit sleeve 15 is inserted into a limit hole 18. The limit hole 18 is opened on one side of the U-shaped frame 11. A side plate 4 is fixedly connected to one side of the back plate 12. A support frame 3 is slidably connected to one side of the side plate 4. One side of the support frame 3 is fixedly connected to the guide frame 2. A telescopic rod 7 is fixedly connected to one side of the first sponge suction cup 6. The other end of the telescopic rod 7 is inserted into the second sponge suction cup 9, and a spirit level 8 is bolted to one side of the telescopic rod 7.

[0027] The mounting rod 16 can be used to assist in the installation of the U-shaped frame 11 on one side of the back plate 12. The end of the mounting rod 16 can be limited by the limiting sleeve 15 to achieve the connection between the mounting rod 16 and the U-shaped frame 11. The mounting rod 16 and the limiting hole 18 can guide the installation of the limiting sleeve 15. The side plate 4 can be used to reinforce one side of the back plate 12 to assist in the stable installation and use of the back plate 12 on the side of the support frame 3. The telescopic rod 7 can be used to adjust the distance between the first sponge suction cup 6 and the second sponge suction cup 9 to support the first sponge suction cup 6 and the second sponge suction cup 9. The bubble level 8 can be used to detect whether there is any positional deviation between the first sponge suction cup 6 and the second sponge suction cup 9, ensuring that the first sponge suction cup 6 and the second sponge suction cup 9 are on the same horizontal line.

[0028] The usage method and working principle of this device are as follows: First, insert the end of the mounting rod 16 through the back plate 12 and the U-shaped frame 11 in sequence. Slide the limiting sleeve 15 along the axial direction of the mounting rod 16 so that the limiting sleeve 15 is inserted into the limiting hole 18, which allows the U-shaped frame 11 to be installed on one side of the back plate 12. Rotate the U-shaped frame 11, and the guide rod 19 slides inside the guide ring 17. The mounting rod 16 and the limiting sleeve 15 rotate with the U-shaped frame 11, while the back plate 12 does not rotate. Adjust the usage direction of the U-shaped frame 11. After adjustment, rotate the limiting screw 13 so that the end of the limiting screw 13 is inserted into the guide rod 19. Then, insert two limiting bolts 14 on one side of the back plate 12 so that the ends of the limiting bolts 14 penetrate the U-shaped frame 11 to position the U-shaped frame 11. The sliding of the inner and outer rods of the telescopic rod 7 can change the position of the sponge suction cup 6 and the sponge suction cup 9. The distance between them is then fixed by inserting a pin into one side of the telescopic rod 7. The extension length of the sponge suction cup 16 and sponge suction cup 29 can be adjusted by the screw 10 on one side of the sponge suction cup 16 and sponge suction cup 29. Thus, when the sponge suction cup 16 and sponge suction cup 29 are used downwards, the usage height of the sponge suction cup 16 and sponge suction cup 29 can be changed. During the adjustment process, the position of the bubble inside the level bubble 8 can be used to determine whether the sponge suction cup 16 and sponge suction cup 29 are on the same horizontal line. If there is a positional deviation, the screw 10 can be rotated to adjust. The limiting sleeve 15 is separated from the limiting hole 18 and the mounting rod 16 in sequence. The limiting screw 13 is rotated in the opposite direction, and then the two limiting bolts 14 are removed. The U-shaped frame 11 and sponge suction cup 16 and sponge suction cup 29 can be quickly replaced on one side of the back plate 12.
