[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model provides a fixture for installation in a purification project, including a base 1. A bracket 3 is fixedly connected to the upper center of the base 1. A movable frame 23 is movably connected inside the bracket 3. A mounting plate 4 is fixedly connected to the top of the movable frame 23. Mounting frames 5 are fixedly connected to both ends of the upper part of the mounting plate 4. A fixing block 19 is fixedly connected to the inner side of the left mounting frame 5. Mounting holes 2 are provided at the four ends of the base 1. The fixture can be supported by the bracket 3 and the movable frame 23, improving its stability during use. Furthermore, the mounting holes 2 facilitate the fixation of the entire device by the staff.

[0027] An L-shaped frame 9 is fixedly connected to the outer end of the right mounting bracket 5. A screw 13 is rotatably connected inside the L-shaped frame 9. A movable block 8 is threadedly fitted to the outer end of the screw 13. The movable block 8 is installed inside the right mounting bracket 5. Arc-shaped clamping plate 2 7 and arc-shaped clamping plate 1 6 are installed inside the movable block 8 and the fixed block 19 respectively. The connection point of the two purification engineering pipes is brought into contact with arc-shaped clamping plate 2 7. Then, the screw 13 is rotated. Under the action of the threaded engagement, the arc-shaped clamping plate 6 can be driven to move inward. With the help of arc-shaped clamping plate 2 7, the pipes can be clamped and positioned to ensure the stability of the connection point of the two pipes.

[0028] The two ends of the fixed block 19 are fixedly connected to slider 14, which is slidably connected inside the mounting bracket 5. By setting slider 14, the stability of the movable block 8 when moving can be improved.

[0029] The mounting bracket 5 has a sliding groove 15 on the inner bottom of the arc-shaped clamping plate 7. A sliding rod 16 is fixedly connected inside the sliding groove 15. A connecting plate 17 is fixedly connected to the bottom of the movable block 8. The connecting plate 17 is slidably connected to the sliding rod 16. Setting the sliding groove 15, sliding rod 16 and connecting plate 17 at the bottom of the arc-shaped clamping plate 7 can improve the stability of the entire clamping assembly and improve its clamping effect.

[0030] The inner ends of the fixed block 19 and the movable block 8 are provided with limiting grooves 20. The outer ends of the arc-shaped clamping plate 16 and the arc-shaped clamping plate 27 are fixedly connected to the limiting block 18. The fixed block 19 and the movable block 8 are internally threaded with positioning bolts 22. The positioning bolts 22 and the internal screw holes of the limiting block 18 are mutually engaged, and the bottom threads of the positioning bolts 22 are engaged with nuts 21. The quick correspondence between the limiting block 18 and the limiting groove 20 allows the staff to quickly assemble and disassemble the two arc-shaped clamping plates. The appropriate arc-shaped clamping plate is selected according to the diameter of the pipe to improve the applicability of the device. Secondly, the positioning bolts 22 and nuts 21 can improve the locking effect and increase the stability after installation. The inner ends of the arc-shaped clamping plates 16 and 27 are machined with annular grooves for embedding sealing gaskets (such as silicone gaskets). The groove depth is slightly less than the thickness of the sealing gasket to form an interference fit, ensuring that the sealing gasket is not easy to fall off. The sealing gasket material is corrosion-resistant silicone, which is suitable for chemical cleaning agents in purification projects.

[0031] The outer end of the movable frame 23 has a sliding groove 10, and the inner end of the bracket 3 is fixedly connected to a slider 24. The bracket 3 has a threaded connection to a positioning bolt 11. The sliding groove 10 has several threaded holes 12, which engage with the positioning bolts 11. The positioning bolts 11 have self-locking threads (such as fine threads) to prevent loosening under vibration. Additionally, a local protrusion is designed at the threaded connection of the bracket 3 to form a mechanical stop, reducing the risk of the bolts completely coming loose. A polytetrafluoroethylene coating is added to the contact surface between the slider 24 and the sliding groove 10 to reduce sliding friction, making height adjustment smoother and preventing jamming during manual pulling. This improves durability in humid environments.

[0032] Working principle: During use, the operator installs the entire clamp at the connection of two cleanroom pipelines. Then, the height of the device is adjusted according to the height of the pipelines. Loosening the positioning bolt 11, the operator pulls the entire clamping assembly upwards to adjust the height of the device. After adjusting to the appropriate position, retightening the positioning bolt 11 quickly fixes the movable frame 23, improving its support effect. Then, the connection of the two cleanroom pipelines is brought into contact with the arc-shaped clamp 7. Next, the screw 13 is rotated, and the arc-shaped clamp 6 moves inward under the action of the threaded engagement. Together with the arc-shaped clamp 7, it can clamp and position the pipelines to ensure the stability of the connection between the two pipelines. In addition, the sealing gasket installed inside the two arc-shaped clamps can improve the sealing effect of the connection and reduce the installation intensity for the operator.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
