[0003] In the existing technology, the exhaust pipe and the main pipe are detachably connected in the charging and degassing system of a high vacuum exhaust station. During the installation of the exhaust pipe in the charging and degassing system, it is necessary to fix and seal the exhaust pipe and the main pipe to ensure the stability and sealing of the exhaust pipe connection. However, the installation and positioning of the exhaust pipe in the charging and degassing system of a high vacuum exhaust station is mainly done manually. This not only requires a large number of parts, but also involves complicated operation steps, which is time-consuming and labor-intensive, affecting the convenience of operation and making it difficult to meet the usage requirements. Therefore, a pipe holding mechanism for a high vacuum exhaust station is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] This utility model provides, for example Figure 1-3 The tube-holding mechanism of a high-vacuum exhaust station shown includes a main pipe 100, an exhaust pipe 300, and a tube-holding assembly 200, as follows: Figure 1 As shown, a hydraulic pipe-cutting mechanism is located above the pipe-clamping assembly 200 to cut the exhaust pipe 300. A branch pipe 101, connected to the interior of the main pipe 100, is located at the top of the main pipe 100. A connecting pipe head 102 is connected to the top of the branch pipe 101. The bottom of the outer wall of the exhaust pipe 300 is slidably connected to the inner wall of the connecting pipe head 102. The pipe-clamping assembly 200 is fixedly installed on the outer wall of the main pipe 100 and is used for fixing and sealing the exhaust pipe 300 and the connecting pipe head 102. The exhaust pipe... After the bottom of the exhaust pipe 300 is inserted into the connecting pipe head 102 on the main pipe 100, the pipe clamping assembly 200 can be driven to move, fixing and sealing the exhaust pipe 300 and the connecting pipe head 102. This makes the installation of the exhaust pipe 300 not only stable but also highly airtight. Moreover, by using the pipe clamping assembly 200 to fix and seal the exhaust pipe 300 and the connecting pipe head 102, the tediousness of manual installation can be avoided, improving the convenience and efficiency of exhaust pipe 300 installation and better meeting the needs of actual use.

[0025] The pipe clamping assembly 200 includes a sleeve 202, a passive compression member, and a lifting drive assembly. The sleeve 202 is slidably fitted onto the outer wall of the connecting pipe head 102. A horn-shaped groove 203 for the exhaust pipe 300 to pass through is formed at the top of the sleeve 202. The top of the horn-shaped groove 203 is a funnel shape, wider at the top and narrower at the bottom. The passive compression member is movably disposed inside the sleeve 202. The outer wall of the exhaust pipe 300 passes through the sleeve 202 and the passive compression member sequentially and extends to the inner side of the connecting pipe head 102. The lifting drive assembly is used to drive... The sleeve 202 descends and compresses the passive extrusion component. The passive extrusion component clamps and seals the exhaust pipe 300 through the compression of the sleeve 202. The sleeve 202 is driven to rise and fall at the top of the connecting pipe head 102 by the lifting drive component. The sleeve 202 compresses the passive extrusion component during the descent. The compression action makes the passive extrusion component clamp, fix and seal the position between the exhaust pipe 300 and the connecting pipe head 102, achieving the function of one-click fixing and sealing. The operation is simple, convenient and efficient.

[0026] Furthermore, the passive extrusion component includes an annular seat 204, which is a hollow annulus. Mounting grooves are provided at the center of both the top and bottom of the annular seat 204. Elastic rubber rings 205 are fixedly connected to the mounting grooves at both the top and bottom of the annular seat 204. The cross-section of the elastic rubber rings 205 is cylindrical, and the elastic rubber rings 205 are made of elastic rubber. The thickness of the elastic rubber rings 205 is greater than the depth of the mounting grooves. Due to the elastic deformation properties of the elastic rubber rings 205, and the fact that the depth of the mounting grooves is less than the thickness of the elastic rubber rings 205, the sleeve 202, during its descent, can clamp the annular seat 204 between the connecting pipe head 102 and the sleeve 202. Simultaneously, the connecting pipe head 102 and the sleeve 202 provide pressure to the annular seat 204. The opposing compressive force can compress the elastic rubber ring 205 to undergo elastic deformation, causing the elastic rubber ring 205 to deform into a flat ring shape. This reduces the inner diameter of the elastic rubber ring 205, thus compressing and clamping the outer wall of the exhaust pipe 300. This keeps the exhaust pipe 300 relatively fixed with the elastic rubber ring 205 and the ring seat 204. At the same time, since the ring seat 204 is clamped between the connecting pipe head 102 and the sleeve 202, the position of the exhaust pipe 300 between them can be fixed. In addition, the elastic rubber ring 205 can also achieve a sealing effect between the exhaust pipe 300 and the sleeve 202 and the connecting pipe head 102, so that the exhaust pipe 300 can be fixed in the installation position while sealing the connection position with the connecting pipe head 102.

[0027] In a preferred embodiment, the lifting drive assembly includes a door frame bracket 201, a sleeve 202 fixedly connected to the middle of the top of the door frame bracket 201, and a sealing cylinder 104 located at the bottom inner side of the door frame bracket 201. The sealing cylinder 104 drives the sleeve 202 to rise and fall via the door frame bracket 201. A connecting seat 103 is fixedly connected to the top of the sealing cylinder 104, and the top of the connecting seat 103 is fixedly connected to the outer wall of the main pipe 100. The connecting seat 103 facilitates the installation and fixation of the sealing cylinder 104 below the main pipe 100, allowing the sealing cylinder to... The installation of 104 does not occupy external space and has a high degree of integration. The door frame bracket 201 consists of two cover plates at the top and bottom and a fixed column connecting the ends of the two cover plates. The whole is in the shape of a door frame, which makes it easy to fit on the outside of the main pipe 100, making the installation of the door frame bracket 201 more convenient and adaptable. The door frame bracket 201 enables the sealing cylinder 104 to drive the sleeve 202 to move up and down, thereby achieving the fixed sealing and unlocking between the exhaust pipe 300 and the connecting pipe head 102, making the installation of the exhaust pipe 300 more convenient.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
