Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] The directional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "side", etc., are only references to the directions in the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention. In addition, in the drawings, structures that are similar or the same are denoted by the same reference numerals.

[0029] Refer to Figures 1 to 7 Specifically, refer to Figure 1 and Figure 2 which shows an embodiment of the bellows auxiliary installation device provided by the present invention. The structure and working principle of the bellows auxiliary installation device will be described in detail below with reference to the accompanying drawings of the specification. The bellows auxiliary installation device includes a first support member 10 and a second support member 20; the two ends of the first support member 10 are respectively a first end 101 and a second end 102, and an upper fixing portion 40 of the bellows is provided on the first end 101; the two ends of the second support member 20 are respectively a third end 201 and a fourth end 202, a lower fixing portion 41 of the bellows is provided on the third end 201, the fourth end 202 is detachably connected to the second end 102, and the third end 201 and the first end 101 are away from each other.

[0030] In a specific implementation, the bellows 200 is a tubular structure composed of foldable annular or spiral thin plates, often made of materials such as metal or plastic. It has a series of parallel ridges and grooves on its surface. Due to its special structure, the bellows 200 can expand and contract in any direction. The bellows 200 is often used for multi-degree-of-freedom displacement compensation functions under sealed conditions and is a widely used elastic compensation element in fluid systems. When the bellows 200 is actually installed, it cannot maintain a vertical state and a fixed length in its free state. Therefore, the bellows 200 will expand and contract during the installation process, causing difficulties in installation. In this embodiment, a bellows auxiliary installation device is used to assist in the installation of the bellows 200. The bellows auxiliary installation device includes a first support member 10 and a second support member 20. The whole of the first support member 10 and the whole of the second support member 20 are both in the shape of straight rods. The two ends of the first support member 10 are a first end 101 and a second end 102, that is, the first end 101 and the second end 102 are the two ends of the first support member 10 that are opposite to each other in the axial direction. A bellows upper end fixing part 40 is provided on the first end 101 of the first support member 10. The bellows upper end fixing part 40 is used to connect and fix one of the two ends of the bellows 200. The two ends of the second support member 20 are a third end 201 and a fourth end 202, that is, the third end 201 and the fourth end 202 are the two ends of the second support member 20 that are opposite to each other in the axial direction. A bellows lower end fixing part 41 is provided on the third end 201 of the second support member 20. The bellows lower end fixing part 41 is used to connect and fix the other end of the bellows 200. The third end 201 of the second support member 20 and the first end 101 of the first support member 10 are away from each other. The connections between the bellows upper end fixing part 40 and the bellows lower end fixing part 41 and the two ends of the bellows 200 are both detachable connections. The bellows upper end fixing part 40 can specifically be set as a bolt structure and is detachably connected to the two ends of the bellows 200 by means of threaded connection. The fourth end 202 of the second support member 20 and the second end 102 of the first support member 10 are detachably connected. When the fourth end 202 of the second support member 20 and the second end 102 of the first support member 10 are connected, the first support member 10 and the second support member 20 are taken as a whole, and their relative positions remain fixed. When affected by an external force, the first support member 10 cannot move independently relative to the second support member 20, and the second support member 20 cannot move independently relative to the first support member 10. When actually installing the bellows 200, after the bellows upper end fixing part 40 on the first end 101 of the first support member 10 is connected and fixed to one end of the bellows 200, the first support member 10 and one end of the bellows 200 are taken as a whole. After the bellows lower end fixing part 41 on the fourth end 202 of the second support member 20 is connected and fixed to the other end of the bellows 200, the second support member 20 and the other end of the bellows 200 are taken as a whole.After connecting the second end 102 of the first support member 10 to the fourth end 202 of the second support member 20, the first support member 10 and the second support member 20 are connected as a whole, and the relative positions of the first support member 10 and the second support member 20 remain fixed. The first support member 10 and the second support member 20 together support and fix both ends of the bellows 200, keeping the relative positions of both ends of the bellows 200 fixed, that is, both ends of the bellows 200 are positioned by the first support member 10 and the second support member 20 that are connected together, so that both ends of the bellows 200 cannot move freely, and the distance between both ends of the bellows 200 remains unchanged. Then the bellows 200 can be installed at the required installation location, and the relative positions between both ends of the bellows 200 always remain fixed during the installation process, and the whole bellows 200 cannot expand or contract. No matter at which angle the bellows 200 is installed, the bellows 200 will not expand or contract, and the installation is very convenient.

[0031] In this embodiment, the upper bellows fixing part on the first end of the first support member and the lower bellows fixing part on the third end of the second support member are respectively connected and fixed to both ends of the bellows. By connecting the fourth end of the second support member to the second end of the first support member, the first end of the first support member and the third end of the second support member respectively support both ends of the bellows, thereby keeping the relative positions of both ends of the bellows fixed to limit the expansion and contraction of the bellows, making the installation of the bellows more convenient.

[0032] In one embodiment, referring to Figure 1 and Figure 2, the corrugated pipe auxiliary installation device further includes an adjustment assembly 30. An expansion channel 11 is axially provided at the second end 102 of the first support member 10. The fourth end 202 of the second support member 20 is movably inserted into the expansion channel 11. The adjustment assembly 30 is provided at the second end 102 of the first support member 10 and is connected to the fourth end 202 of the second support member 20. In a specific implementation, an expansion channel 11 is provided along the axis of the second end 102 of the first support member 10, so that the second end 102 of the first support member 10 forms a sleeve structure. The depth of the expansion channel 11 occupies most of the axial length of the first support member 10. The fourth end 202 of the second support member 20 is integrally inserted into the expansion channel 11, and the fourth end 202 of the second support member 20 can extend into the expansion channel 11 by any length. The auxiliary installation assembly further includes an adjustment assembly 30. The adjustment assembly 30 is installed at the second end 102 of the first support member 10 and is connected to the fourth end 202 of the second support member 20. The adjustment assembly 30 can adjust the length of the fourth end 202 of the second support member 20 extending into the expansion channel 11. By changing the length of the second end 102 of the second support member 20 extending into the expansion channel 11, the adjustment assembly 30 can make the third end 201 of the second support member 20 approach or move away from the first end 101 of the first support member 10, so as to make the two ends of the corrugated pipe 200 approach or move away from each other. The more the adjustment assembly 30 adjusts the length of the fourth end 202 of the second support member 20 extending into the expansion channel 11, the closer the third end 201 of the second support member 20 is to the first end 101 of the first support member 10, and the smaller the distance between the two ends of the corrugated pipe 200; and the less the adjustment assembly 30 adjusts the length of the fourth end 202 of the second support member 20 extending into the expansion channel 11, the farther the third end 201 of the second support member 20 is from the first end 101 of the first support member 10, and the larger the distance between the two ends of the corrugated pipe 200. Thus, by adjusting the length of the second end 102 of the second support member 20 extending into the expansion channel 11 through the adjustment assembly 30, the installation length requirements of the corrugated pipe 200 under different installation conditions are met, and the applicable range is wider.

[0033] Further, referring to Figure 3, the adjusting assembly 30 includes an adjusting nut 31. The adjusting nut 31 is sleeved on the second end 102 of the first support member 10 and is rotatable relative to the second end 102 of the first support member 10. The fourth end 202 of the second support member 20 passes through the adjusting nut 31 and is threadedly connected thereto. In a specific implementation, the adjusting assembly 30 includes an adjusting nut 31. The adjusting nut 31 is sleeved on the second end 102 of the first support member 10 and is rotatable relative to the second end 102 of the first support member 10. The adjusting nut 31 can rotate freely around the second end 102 of the first support member 10. The second support member 20 is a threaded rod structure as a whole. The fourth end 202 of the second support member 20 is integrally inserted into the threaded hole of the adjusting nut 31 and is threadedly connected to the threaded hole on the adjusting nut 31. When the adjusting nut 31 is rotated, the position of the second end 102 of the first support member 10 remains unchanged relative to the adjusting nut 31. However, since the fourth end 202 of the second support member 20 is threadedly connected to the adjusting nut 31, under the guiding action of the thread, the adjusting nut 31 moves in the axial direction of the second support member 20. When the direction of rotating the adjusting nut 31 is different, the moving direction of the adjusting nut 31 is different. When the adjusting nut 31 is rotated and gradually moves towards the third end 201 of the second support member 20, the length of the fourth end 202 of the second support member 20 extending into the telescopic channel 11 gradually increases, and the third end 201 of the second support member 20 gradually approaches the first end 101 of the first support member 10. The distance between the two ends of the bellows 200 decreases accordingly. When the adjusting nut 31 is rotated and gradually moves away from the third end 201 of the second support member 20, the length of the fourth end 202 of the second support member 20 extending into the telescopic channel 11 gradually decreases, and the third end 201 of the second support member 20 gradually moves away from the first end 101 of the first support member 10. The distance between the two ends of the bellows 200 increases accordingly. In this way, the adjustment of different installation lengths of the bellows 200 is achieved by rotating the adjusting nut 31, which is very convenient.

[0034] Furthermore, referring to Figure 3The adjustment assembly 30 further includes a locking member 32. A movable groove 310 is recessed on the side of the adjustment nut 31 facing the first support member 10. The second end 102 of the first support member 10 is accommodated in the movable groove 310. The adjustment nut 31 is provided with an adjustment hole 311 extending through the movable groove 310 along its radial direction. The locking member 32 can be movably inserted into the adjustment hole 311 and extends into the movable groove 310 to abut against the side wall of the second end 102 of the first support member 10. In a specific implementation, a movable groove 310 is recessed on the side of the adjustment nut 31 facing the first support member 10. The movable groove 310 is a circular groove structure with a certain depth in the axial direction of the adjustment nut 31. The outer side wall of the second end 102 of the first support member 10 is designed to match the movable groove 310. The second end 102 of the first support member 10 is accommodated in the movable groove 310 and can rotate freely in the movable groove 310. The adjusting nut 31 has an adjusting hole 311 in its radial direction. The adjusting hole 311 penetrates into the movable groove 310 along the radial direction of the adjusting nut 31. The adjusting hole 311 connects the radial outer side of the adjusting nut 31 with the movable groove 310. The adjusting assembly 30 also includes a locking member 32. The locking member 32 is a latch structure, which is mainly used to fix the second end 102 of the first support member 10 with the adjusting nut 31. The locking member 32 is movably inserted into the adjusting hole 311 on the adjusting nut 31. A part of the locking member 32 is outside the adjusting nut 31 for manual operation. The locking member 32 as a whole can be telescopically moved in the adjusting hole 311 along the radial direction of the adjusting nut 31, and the locking member 32 extends into the movable groove 310 and abuts against the side wall of the second end 102 of the first support member 10. In the process of rotating the adjusting nut 31 to adjust the length of the fourth end 202 of the second support member 20 extending into the telescopic channel 11, the locking member 32 does not need to abut against the second end 102 of the first support member 10. After the adjusting nut 31 is rotated to adjust the corresponding length of the fourth end 202 of the second support member 20 extending into the telescopic channel 11, the locking member 32 is moved to abut against the side wall of the second end 102 of the first support member 10, so that the second end 102 of the first support member 10 is locked in the movable groove 310 of the adjusting nut 31, and the second end 102 of the first support member 10 will not easily break away from the adjusting nut 31, so that the connection between the first support member 10 and the second support member 20 remains stable, and the installation is more stable.

[0035] Specifically, refer to Figure 3, a limiting flange 12 is concavely provided on the side wall of the second end 102 of the first support member 10, and the locking member 32 extends into the limiting flange 12. The limiting flange 12 is arranged around the side wall of the second end 102 of the first support member 10. The locking member 32 passing through the adjustment hole 311 extends into the limiting flange 12. After rotating the adjustment nut 31 to adjust the corresponding length of the fourth end 202 of the second support member 20 extending into the telescopic channel 11, the locking member 32 extending into the limiting flange 12 locks the second end 102 of the first support member 10 in the movable groove 310 of the adjustment nut 31. Under the cooperation and limitation of the locking member 32 and the limiting flange 12, the first support member 10 cannot move axially along the adjustment nut 31, and the connection stability between the second end 102 of the first support member 10 and the adjustment nut 31 is better.

[0036] In one embodiment, the locking member 32 is threadedly connected to the adjustment hole 311. In a specific implementation, the adjustment hole 311 in the radial direction of the adjustment nut 31 is arranged as a threaded hole structure, and the locking member 32 is provided with a threaded pin structure. The locking member 32 is threadedly connected to the adjustment hole 311. By rotating the locking member 32, it is possible to control the movement of the locking member 32 along the radial direction of the adjustment nut 31 in the adjustment hole 311. After rotating the adjustment nut 31 to adjust the installation length of the bellows 200, only by rotating the locking member 32 can the second end 102 of the first support member 10 be fixed to the adjustment nut 31, which is very convenient.

[0037] In one embodiment, referring to Figure 1 , the bellows auxiliary installation device further includes a retaining ring 50, and the retaining ring 50 is respectively arranged around the upper fixed part 40 and the lower fixed part 41 of the bellows. In a specific implementation, the retaining ring is in a ring structure. Two retaining rings 50 are respectively arranged around the upper fixed part 40 and the lower fixed part 41 of the bellows, that is, one retaining ring 50 is arranged around the upper fixed part 40 of the bellows, and the other retaining ring 50 is arranged around the lower fixed part 41 of the bellows. The retaining ring 50 protrudes in the radial direction of the upper fixed part 40 and the lower fixed part 41 of the bellows, and the retaining ring 50 cannot move relative to the upper fixed part 40 and the lower fixed part 41 of the bellows. During the process of disassembling the bellows 200, the retaining ring 50 is mainly used to cooperate with the bellows 200 to guide the separation of the bellows 200 from the installation site.

[0038] Further, referring to Figure 4, annular grooves 401 are provided on the side walls of both the upper fixing part 40 and the lower fixing part 41 of the corrugated pipe. The inner side of the retaining ring 50 is embedded in the annular groove 401 and is rotatable relative to the annular groove 401. In a specific implementation, annular grooves 401 are provided on the side walls of both the upper fixing part 40 and the lower fixing part 41 of the corrugated pipe. The annular groove 401 is specifically an annular groove structure provided on the side walls of the upper fixing part 40 and the lower fixing part 41 of the corrugated pipe. The retaining ring 50 is integrally annular. The inner side of the retaining ring 50 is embedded in the annular groove 401 on the side walls of the upper fixing part 40 and the lower fixing part 41 of the corrugated pipe. The inner ring surface of the retaining ring 50 is in clearance fit with the annular groove 401, and the retaining ring 50 as a whole can rotate around the annular groove 401.

[0039] In one embodiment, a corrugated pipe 200 is provided, which can be referred to Figures 2 to 7 , the corrugated pipe 200 includes a corrugated pipe auxiliary installation device. The corrugated pipe 200 is connected to the corrugated pipe auxiliary installation device for application.

When installing the corrugated pipe 200, after the first support member 10 and the second support member 20 are connected, the upper fixing portion 40 of the corrugated pipe supports the installation flange 2010 at one end of the corrugated pipe 200, and the lower fixing portion 41 of the corrugated pipe supports the installation flange 2010 at the other end of the corrugated pipe 200. The relative positions of the installation flanges 2010 at both ends of the corrugated pipe 200 are kept fixed, and the overall length of the corrugated pipe 200 is fixed. At this time, the entire corrugated pipe auxiliary installation device is moved to the installation site of the corrugated pipe 200, the installation position and angle are adjusted, and the parts of the upper fixing portion 40 and the lower fixing portion 41 of the corrugated pipe extending outside the through hole 2011 are connected and fixed to the installation site. After the installation flanges 2010 at both ends of the corrugated pipe 200 are fixed to the installation site, only by rotating the first support member 10 and the second support member 20 respectively, the connection between the first support member 10 and the upper fixing portion 40 of the corrugated pipe, and the connection between the second support member 20 and the lower fixing portion 41 of the corrugated pipe can be released. Leave the upper fixing portion 40 and the lower fixing portion 41 of the corrugated pipe fixed to the installation flanges 2010 at both ends of the corrugated pipe 200 at the installation site respectively. When it is necessary to disassemble the corrugated pipe 200, reconnect the first end 101 of the first support member 10 to the upper fixing portion 40 of the corrugated pipe, and connect the third end 201 of the second support member 20 to the upper fixing portion 40 of the corrugated pipe. After connection, release the connection between the upper fixing portion 40 and the lower fixing portion 41 of the corrugated pipe and the installation site. At this time, the installation flanges 2010 at both ends of the corrugated pipe 200 are supported by the upper fixing portion 40 and the lower fixing portion 41 of the corrugated pipe respectively, and the corrugated pipe 200 will not expand or contract as a whole and always remains in a stable state. The entire installation and disassembly process is very convenient.

[0041] Furthermore, it can be referred to Figure 4, on one side of the mounting flanges 2010 at both ends of the bellows 200, which is away from the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows, counterbores 2012 communicating with the through holes 2011 are provided. The diameter of the counterbores 2012 is larger than that of the through holes 2011. The upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows penetrate through the counterbores 2012 and extend out of the counterbores 2012. The retaining rings 50 are received in the counterbores 2012 and stop at the edges of the through holes 2011. In a specific implementation, on one side of the mounting flanges 2010 at both ends of the bellows 200, which is away from the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows, counterbores 2012 are provided. The counterbores 2012 communicate with the through holes 2011. The diameter of the counterbores 2012 is larger than that of the through holes 2011. The upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows respectively pass through the counterbores 2012 on the mounting flanges 2010 at both ends of the bellows 200 and extend out of the counterbores 2012. The parts of the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows that extend out of the counterbores 2012 are used to be connected and fixed to the installation part. The retaining rings 50 on the upper fixing part 40 of the bellows auxiliary installation device are received in the counterbores 2012 of the mounting flange 2010 at one end of the bellows 200, and the retaining rings 50 on the lower fixing part 41 of the bellows are received in the counterbores 2012 of the mounting flange 2010 at one end of the bellows 200. The outer diameter of the retaining rings 50 is designed to be smaller than the diameter of the through holes 2011, so that the retaining rings 50 stop at the edges of the through holes 2011 in the counterbores 2012. When disassembling the bellows 200, taking the example that the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows are connected to the installation part by a threaded connection method, during the process of disconnecting the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows from the installation part, after the upper fixing part 40 of the bellows and the second fixing part are loosened, they gradually move away from the installation part respectively. Since the edges of the through holes 2011 block the retaining rings 50, the retaining rings 50 fix the axial position of the installation part and the upper fixing part 40 of the bellows. The retaining rings 50 in the counterbores 2012 move along with the movement of the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows. The retaining rings 50 generate a thrust force on the edges of the through holes 2011, and drive the mounting flange 2010 to move while loosening the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows. In the actual application scenario of the bellows 200, such as when the bellows 200 is applied to a semiconductor reaction chamber, the mounting flanges 2010 at both ends of the bellows 200 are likely to adhere to the installation part of the semiconductor reaction chamber. However, the retaining rings 50 can automatically separate the adhered mounting flange 2010 from the installation part, eliminating the operation of adhesively separating the mounting flange 2010 from the installation part, making the disassembly of the bellows 200 more convenient.

[0042] In the bellows of this embodiment, due to the adoption of the bellows auxiliary installation device provided by the present utility model, the installation difficulty is reduced, and the installation is more convenient and rapid.

[0043] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
