In the process of using existing clean pipes, bolts and flanges are used to fix the pipes and sealing sleeves can achieve the effect of connecting and sealing the pipes, but this method has poor sealing effect and multiple bolts are inconvenient to disassemble, which increases the workload of workers and reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect sealing structure for pipes in a cleanroom, comprising a first pipe with a first stop fixedly connected to one end, a second pipe provided on the side of the first pipe, a second stop fixedly connected to one end of the second pipe, the first stop and the second stop fitting together, and locking blocks provided on the outer surfaces of both the first and second stops, the inner surface of the locking blocks having a positioning groove, the surfaces of the first and second stops facing the positioning grooves being fixedly connected to positioning blocks, the surface of the second stop having a groove, and a supporting slider fixedly connected to the inner wall of the groove of the second stop, a sliding baffle provided on the inner wall of the groove of the second stop, an auxiliary sealing strip fixedly connected to the side surface of the sliding baffle, and a linkage sealing mechanism provided on the outer surface of the second stop, which pushes the linkage slider and the air guide piston column through the inner wall of one side of the locking block to fill the supporting sealing airbag with air, thereby expanding and fitting the outer surface of the sliding baffle.

[0006] Preferably, the first pipe is connected to the first stop, the second pipe is connected to the second stop, and the locking block is a semi-circular design, with two locking blocks on one side fixed together by bolts.

[0007] Using the above technical solution, the locking block is a semi-circular design. The two locking blocks on one side are fixed together by bolts. The semi-circular design facilitates installation and disassembly. The bolt fixing enhances the stability of the connection, ensuring that the first stop and the second stop fit tightly together and preventing loosening at the pipe connection.

[0008] Preferably, the positioning block is cylindrical in design, and the positioning block is arranged in a circular array about the center of the first stop and the second stop, and the positioning groove and the positioning block are engaged.

[0009] Using the above technical solution, the positioning block is cylindrical in design and is arranged in a circular array about the center of the first and second blocks, and the positioning groove and the positioning block form a snap-fit ​​connection.

[0010] Preferably, the vertical cross-section of the support slider is T-shaped, the side surface of the sliding baffle is provided with a support groove, and the sliding baffle is slidably connected to the support slider through the support groove. A spring is connected between the support groove and the support slider, and the auxiliary sealing strip is annular.

[0011] By adopting the above technical solution, the sliding connection of the T-shaped support slider and the support slot, combined with the elasticity of the spring, allows the sliding baffle to slide flexibly, playing a buffering and adjustment role in the process of pipe connection and sealing. The annular auxiliary sealing strip can effectively enhance the sealing of the pipe connection and prevent gas or liquid leakage.

[0012] Preferably, the linkage sealing mechanism includes a linkage slider, which is embedded in the outer surface of the second stop block. One end of the linkage slider is fixedly connected to a guide piston column, and a supporting sealing airbag is fixedly connected to the inner wall of the groove of the second stop block.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a quick-connect sealing structure for pipes in a cleanroom, comprising a first pipe 1, a first stop 2, a second pipe 3, a second stop 4, a locking block 5, a positioning groove 6, a positioning block 7, a supporting slider 8, a supporting slot 9, a sliding baffle 10, an auxiliary sealing strip 11, a linkage slider 12, an air guide piston column 13, and a supporting sealing airbag 14. The first pipe 1 has a first stop 2 fixedly connected to one end. A second pipe 3 is provided on the side of the first pipe 1, and a second stop 4 is fixedly connected to one end of the second pipe 3. The first pipe 1 is connected to the first stop 2, and the second pipe 3 is connected to the second stop 4. The locking blocks 5 are connected and have a semi-circular design. The two locking blocks 5 on one side are fixed by bolts to connect the first pipe 1 and the second pipe 3, so that the first stop 2 and the second stop 4 fit together. Then, the locking blocks 5 on both sides are spliced ​​and combined. The combined locking blocks 5 on both sides are brought close to the first stop 2 and the second stop 4 respectively. At this time, the positioning block 7 will be aligned with the positioning groove 6. Since the positioning block 7 is cylindrical and arranged in an array about the center of the first stop 2 and the second stop 4, it can quickly and accurately position the two pipes, ensuring the coaxiality of the first pipe 1 and the second pipe 3 and avoiding the offset when the pipes are connected.

[0031] The first stop 2 and the second stop 4 are fitted together, and both the first stop 2 and the second stop 4 have locking blocks 5 on their outer surfaces. The inner surface of the locking blocks 5 has a positioning groove 6. Positioning blocks 7 are fixedly connected to the surfaces of the first stop 2 and the second stop 4 facing the positioning groove 6. The positioning blocks 7 are cylindrical and arranged in an array about the center of the first stop 2 and the second stop 4. The positioning groove 6 and the positioning blocks 7 form a locking connection. The vertical cross-section of the supporting slider 8 is T-shaped. The side of the sliding baffle 10... The surface is provided with a support groove 9, and the sliding baffle 10 is slidably connected to the support slider 8 through the support groove 9. A spring is connected between the support groove 9 and the support slider 8. The auxiliary sealing strip 11 is annular. During the locking process of the locking block 5, the inner wall of the locking block 5 will squeeze the linkage slider 12. The linkage slider 12 is slidably connected to the second stop 4, and its surface facing the second pipe 3 is arc-shaped, making it easy to be pushed. While the linkage slider 12 slides, it drives the fixedly connected air guide piston column 13 to move together.

[0032] The surface of the second stop 4 is provided with a groove, and a support slider 8 is fixedly connected to the inner wall of the groove of the second stop 4. A sliding baffle 10 is provided on the inner wall of the groove of the second stop 4. An auxiliary sealing strip 11 is fixedly connected to the side surface of the sliding baffle 10. The linkage sealing mechanism includes a linkage slider 12, which is embedded in the outer surface of the second stop 4. One end of the linkage slider 12 is fixedly connected to a guide piston column 13. A support sealing airbag 14 is fixedly connected to the inner wall of the groove of the second stop 4. The guide piston column 13 and the second stop 4 are also slidably connected. One end of its piston head is connected to the support sealing airbag 14. As the guide piston column 13 slides, air is filled into the support sealing airbag 14, causing the support sealing airbag 14 to expand.

[0033] The outer surface of the second stop 4 is provided with a linkage sealing mechanism. This mechanism, through the inner wall of the locking block 5 on one side, pushes the linkage slider 12 and the air guide piston 13 to inflate the supporting sealing airbag 14, causing it to expand and adhere to the outer surface of the sliding baffle 10. The linkage slider 12 and the second stop 4 are slidably connected, and a spring connects them. The surface of the linkage slider 12 facing the second pipe 3 is arc-shaped. The air guide piston 13 and the second stop 4 are slidably connected, and one end of the piston head of the air guide piston 13 is connected to the supporting sealing airbag 14. The supporting sealing airbag 14 is a ring-shaped design. After expansion, it will fit against the outer surface of the sliding baffle 10. During this process, the sliding baffle 10 is slidably connected to the supporting slider 8 through the supporting slot 9. A spring is connected between the supporting slot 9 and the supporting slider 8. The spring will play a certain role in buffering and adjustment, so that the sliding baffle 10 can better adapt to the expansion of the supporting sealing airbag 14. At the same time, the ring-shaped auxiliary sealing strip 11 further enhances the sealing effect, effectively prevents gas leakage, and ensures the airtightness and environmental stability of the clean room.

[0034] Working principle: When using this quick-connect sealing structure for cleanroom pipes, the first pipe 1 and the second pipe 3 are connected, and the first stop 2 and the second stop 4 are fitted together. The semi-circular locking block 5 is installed on the outer surface of the first stop 2 and the second stop 4. The two locking blocks 5 on the same side are fixed with bolts. The locking blocks 5 after being combined on both sides are brought close together and fixed. At this time, the cylindrical positioning block 7 is aligned with the positioning groove 6 and engaged, accurately determining the relative position of the two pipes and ensuring coaxiality. When the locking block 5 is fixed, its inner wall pushes the linkage slider 12. The linkage slider 12 drives the air guide piston column 13 to slide. The air guide piston column 13 fills the annular support sealing airbag 14 with air, causing it to expand and fit against the outer surface of the sliding baffle 10. The annular auxiliary sealing strip 11 further enhances the sealing effect and increases the overall practicality.
