Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention. In addition, in the drawings, structures with similar or identical structures are represented by the same reference numerals.

[0029] Reference Figures 1 to 7 For details, please 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 are described in detail below in conjunction with the drawings in the specification. The bellows auxiliary installation device comprises a first support member 10 and a second support member 20; the first support member 10 has a first end 101 and a second end 102 at two ends, respectively, and a bellows upper end fixing portion 40 is provided on the first end 101; the second support member 20 has a third end 201 and a fourth end 202 at two ends, and a bellows lower end fixing portion 41 is provided on the third end 201, and the fourth end 202 is detachably connected to the second end 102, and the third end 201 and the first end 101 are far away from each other.

[0030] In specific implementation, the bellows 200 is a tubular structure composed of foldable annular or spiral thin plates, usually made of metal or plastic, etc., with a series of parallel ridges and grooves on its surface. Due to its special structure, the bellows 200 can be extended and retracted in any direction. The bellows 200 is often used for multi-degree-of-freedom displacement compensation under sealing conditions and is a widely used elastic compensation element in fluid systems. When the bellows 200 is actually installed, the bellows 200 cannot maintain a vertical state and a fixed length in a free state, so the bellows 200 will expand and retract during the installation process, causing difficulties in installation. In this embodiment, a bellows auxiliary installation device is used to assist the installation of the bellows 200. The bellows auxiliary installation device includes a first support member 10 and a second support member 20. The first support member 10 as a whole and the second support member 20 as a whole are both straight rod-shaped. The first support member 10 has two ends, a first end 101 and a second end 102, that is, the first end 101 and the second end 102 are two ends of the first support member 10 that are opposite in the axial direction. A bellows upper end fixing portion 40 is provided on the first end 101 of the first support member 10. The bellows upper end fixing portion 40 is used to connect and fix with 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 two ends of the second support member 20 that are opposite in the axial direction. A bellows lower end fixing portion 41 is provided on the third end 201 of the second support member 20. The bellows lower end fixing portion 41 is used to connect and fix with the other end of the bellows 200. The third end 201 of the second support member 20 is far away from the first end 101 of the first support member 10. The connection between the upper end fixing portion 40 of the bellows and the lower end fixing portion 41 of the bellows and the two ends of the bellows 200 is detachable. The upper end fixing portion 40 of the bellows can be specifically configured as a bolt structure, which is detachably connected to the two ends of the bellows 200 by threaded connection. The fourth end 202 of the second support member 20 is detachably connected to the second end 102 of the first support member 10. 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 as a whole, and the relative positions of the two remain fixed. When affected by 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 the bellows 200 is actually installed, after the upper end fixing portion 40 of the bellows 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 formed as a whole, and after the lower end fixing portion 41 of the bellows 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 formed as a whole.After the second end 102 of the first support member 10 is connected 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 jointly support and fix the two ends of the bellows 200, so that the relative positions of the two ends of the bellows 200 remain fixed, that is, the two ends of the bellows 200 are positioned by the first support member 10 and the second support member 20 connected together, so that the two ends of the bellows 200 cannot move freely, and the distance between the two ends of the bellows 200 remains unchanged. Then the bellows 200 can be installed to the position where it needs to be installed. During the installation process, the relative position between the two ends of the bellows 200 always remains fixed, and the bellows 200 as a whole cannot be extended or retracted. No matter at which angle the bellows 200 is installed, the bellows 200 will not extend or retract, and the installation is very convenient.

[0031] In this embodiment, the upper end fixing portion of the bellows on the first end of the first support member and the lower end fixing portion of the bellows on the third end of the second support member are respectively connected and fixed to the two ends of the bellows, and the fourth end of the second support member is connected to the second end of the first support member, so that the first end of the first support member and the third end of the second support member respectively support the two ends of the bellows, thereby keeping the relative positions of the two 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 2The bellows auxiliary installation device further includes an adjustment component 30. The second end 102 of the first support member 10 is provided with a telescopic channel 11 along the axial direction. The fourth end 202 of the second support member 20 can be movably inserted into the telescopic channel 11. The adjustment component 30 is provided at the second end 102 of the first support member 10 and connected to the fourth end 202 of the second support member 20. In a specific implementation, the second end 102 of the first support member 10 is provided with a telescopic channel 11 along the axial direction 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 telescopic 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 telescopic channel 11. The fourth end 202 of the second support member 20 can extend into the telescopic channel 11 to any length. The auxiliary installation assembly also includes an adjustment assembly 30, which is installed at the second end 102 of the first support member 10 and 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 telescopic channel 11. The adjustment assembly 30 can make the third end 201 of the second support member 20 and the first end 101 of the first support member 10 approach or move away from each other by changing the length of the second end 102 of the second support member 20 extending into the telescopic channel 11, so as to make the two ends of the bellows 200 close to each other or move away from each other. When the fourth end 202 of the second support member 20 is moved closer to or farther away from each other, the more the adjusting component 30 adjusts the fourth end 202 of the second support member 20 to extend into the telescopic passage 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 bellows 200; and the less the fourth end 202 of the second support member 20 is adjusted by the adjusting component 30 to extend into the telescopic passage 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 bellows 200. In this way, the length of the second end 102 of the second support member 20 extending into the telescopic passage 11 is adjusted by the adjusting component 30, which meets the installation length requirements of the bellows 200 under different installation conditions, and has a wider range of applications.

[0033] Further, refer to Figure 3, the adjustment component 30 includes an adjustment nut 31, the adjustment 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, and the fourth end 202 of the second support member 20 is penetrated through the adjustment nut 31 and is threadedly connected thereto. In a specific implementation, the adjustment component 30 includes an adjustment nut 31, the adjustment 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 adjustment nut 31 can freely rotate 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 penetrated through the screw hole of the adjustment nut 31 as a whole and is threadedly connected to the screw hole on the adjustment nut 31. When the adjusting nut 31 is rotated, the position of the second end 102 of the first support member 10 relative to the adjusting nut 31 remains unchanged, and the fourth end 202 of the second support member 20 is threadedly connected to the adjusting nut 31. Under the guidance of the thread, the adjusting nut 31 moves axially of the second support member 20. The direction of rotating the adjusting nut 31 is different, and the direction of movement of the adjusting nut 31 is different. When the rotating adjusting nut 31 gradually moves toward the third end 201 of the second support member 20, the fourth end 202 of the second support member 20 extends into the telescopic channel. As the length of the bellows 200 gradually increases, the third end 201 of the second support member 20 and the first end 101 of the first support member 10 gradually approach each other, and the distance between the two ends of the bellows 200 decreases accordingly; and when the adjusting nut 31 is rotated to gradually move 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, the third end 201 of the second support member 20 and the first end 101 of the first support member 10 gradually move away from each other, and the distance between the two ends of the bellows 200 increases accordingly. In this way, the bellows 200 can be adjusted to different installation lengths by rotating the adjusting nut 31, which is very convenient.

[0034] Furthermore, refer 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 recess 12 is recessed on the side wall of the second end 102 of the first support member 10, and the locking member 32 extends into the limiting recess 12. The limiting recess 12 is arranged around the side wall of the second end 102 of the first support member 10, and the locking member 32 penetrating the adjustment hole 311 extends into the limiting recess 12. After the fourth end 202 of the second support member 20 is adjusted to a corresponding length extending into the telescopic channel 11 by rotating the adjustment nut 31, the locking member 32 extending into the limiting recess 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 restriction of the locking member 32 and the limiting recess 12, the first support member 10 cannot move axially in the adjustment nut 31, and the stability of the connection 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 radial adjustment hole 311 on the adjustment nut 31 is set as a threaded hole structure, and the locking member 32 is set as a threaded pin structure. The locking member 32 is threadedly connected to the adjustment hole 311. By rotating the locking member 32, the locking member 32 can be controlled to move in the adjustment hole 311 along the radial direction of the adjustment nut 31. After rotating the adjustment nut 31 to adjust the installation length of the corrugated tube 200, the second end 102 of the first support member 10 can be fixed to the adjustment nut 31 by simply rotating the locking member 32, which is very convenient.

[0037] In one embodiment, referring to Figure 1 , the bellows auxiliary installation device also includes a retaining ring 50, and the retaining ring 50 is respectively arranged on the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows. In the specific implementation, the retaining ring is an annular structure, and the two retaining rings 50 are respectively arranged on the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows, that is, one retaining ring 50 is arranged on the upper fixing part 40 of the bellows, and another retaining ring 50 is arranged on the lower fixing part 41 of the bellows. The retaining ring 50 as a whole protrudes in the radial direction of the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows, and the retaining ring 50 cannot move relative to the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows. In the process of disassembling the bellows 200, the retaining ring 50 is mainly used to cooperate with the bellows 200 to guide the bellows 200 to separate from the installation part.

[0038] Further, refer to Figure 4, an annular groove 401 is provided on the side wall of both the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows, and the inner side of the retaining ring 50 is embedded in the annular groove 401 and can rotate relative to the annular groove 401. In the specific implementation, annular grooves 401 are provided on the side walls of the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows, and the annular grooves 401 are specifically annular groove structures arranged on the side walls of the upper fixing part 40 of the bellows and the lower fixing part 41 of the bellows. The retaining ring 50 is an annular structure as a whole, and 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 of the bellows and the lower fixing part 41 of the bellows. The inner annular surface of the retaining ring 50 is clearance-matched 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 bellows 200 is provided, which can be referred to Figures 2 to 7 The bellows 200 includes a bellows auxiliary installation device. The bellows 200 is connected with the bellows auxiliary installation device for application. The bellows auxiliary installation device can keep the relative positions of the two ends of the bellows 200 fixed, so that the bellows 200 as a whole remains stable. The bellows 200 will not expand or contract during the installation process, and the installation difficulty of the bellows 200 is lower. Among them, the bellows auxiliary installation device in this embodiment can adopt any bellows auxiliary installation device provided by the present invention. Since the specific structure and working principle of the bellows auxiliary installation device have been described in detail in the previous description, they will not be repeated here for the sake of brevity.

[0040] Further, see Figures 4 to 7, both ends of the bellows 200 are provided with mounting flanges 2010, and the mounting flanges 2010 are provided with through holes 2011, the upper fixing portion 40 of the bellows can be movably penetrated through the through hole 2011 of the mounting flange 2010 at one end of the bellows 200 and extend out of the through hole 2011, and the lower fixing portion 41 of the bellows can be movably penetrated through the through hole 2011 of the mounting flange 2010 at the other end of the bellows 200 and extend out of the through hole 2011, the first end 101 of the first support member 10 is threadedly connected to the upper fixing portion 40 of the bellows, and the third end 201 of the second support member 20 is threadedly connected to the lower fixing portion 41 of the bellows. In a specific implementation, mounting flanges 2010 are provided at both ends of the bellows 200. The mounting flanges 2010 at both ends of the bellows 200 are respectively matched with the upper fixing portion 40 of the bellows and the lower fixing portion 41 of the bellows to connect with the mounting position, that is, the mounting flange 2010 at one end of the bellows 200 is matched with the upper fixing portion 40 of the bellows to connect with the corresponding mounting position, and the mounting flange 2010 at the other end of the bellows 200 is matched with the lower fixing portion 41 of the bellows to connect with the corresponding mounting position, and the connection with the mounting position is threaded. Through holes 2011 are provided on the mounting flanges 2010 at both ends of the bellows 200. The through holes 2011 are through holes on the mounting flanges 2010, which penetrate through both sides of the mounting flanges 2010. The upper fixing portion 40 of the bellows can be movably passed through the through hole 2011 on the mounting flange 2010 connected to one end of the bellows 200 and extend out of the through hole 2011. Similarly, the lower fixing portion 41 of the bellows can be movably passed through the through hole 2011 on the mounting flange 2010 connected to the other end of the bellows 200 and extend out of the through hole 2011. Figure 7As shown, the parts of the upper fixing part 40 and the lower fixing part 41 of the bellows extending out of the through hole 2011 are mainly used to connect and fix with the installation part.

Similarly, the third end 201 of the second support member 20 is threadedly connected with the lower fixing part 41 of the bellows, so that the first support member 10 is connected with the upper fixing part 40 of the bellows as a whole, and the second support member 20 is connected with the lower fixing part 41 of the bellows as a whole. When installing the bellows 200, after the first support member 10 is connected with the second support member 20, the upper fixing part 40 of the bellows supports the mounting flange 2010 at one end of the bellows 200, and the lower fixing part 41 of the bellows supports the mounting flange 2010 at the other end of the bellows 200. The two ends of the bellows 200 are connected. The relative position of the mounting flange 2010 remains fixed, and the overall length of the bellows 200 is fixed. At this time, the entire bellows auxiliary mounting device is moved to the mounting position of the bellows 200, the mounting position and angle are adjusted, and the parts of the upper fixing portion 40 and the lower fixing portion 41 of the bellows extending outside the through hole 2011 are connected and fixed to the mounting position. After the mounting flanges 2010 at both ends of the bellows 200 are fixed to the mounting position, it is only necessary to rotate the first support member 10 and the second support member 20 respectively to release the connection between the first support member 10 and the upper fixing portion 40 of the bellows, and to release the connection between the second support member 20 and the lower fixing portion 41 of the bellows. The upper fixing portion 40 and the lower fixing portion 41 of the bellows are left fixed to the installation position with the mounting flanges 2010 at both ends of the bellows 200 respectively. When the bellows 200 needs to be disassembled, the first end 101 of the first support member 10 is reconnected to the upper fixing portion 40 of the bellows, and the third end 201 of the second support member 20 is connected to the upper fixing portion 40 of the bellows. After the connection is completed, the connection between the upper fixing portion 40 and the lower fixing portion 41 of the bellows and the installation position is released. At this time, the mounting flanges 2010 at both ends of the bellows 200 are supported by the upper fixing portion 40 and the lower fixing portion 41 of the bellows respectively. The bellows 200 as a whole will not expand or contract and always remain in a stable state. The entire installation and disassembly process is very convenient.

[0041] Further, see Figure 4The mounting flanges 2010 at both ends of the bellows 200 are provided with countersunk holes 2012 penetrating the through hole 2011 on the side away from the upper fixing portion 40 of the bellows and the lower fixing portion 41 of the bellows. The countersunk holes 2012 have a diameter greater than that of the through hole 2011. The upper fixing portion 40 of the bellows and the lower fixing portion 41 of the bellows are penetrated through the countersunk holes 2012 and extend out of the countersunk holes 2012. The retaining ring 50 is received in the countersunk holes 2012 and stopped at the edge of the through hole 2011. In a specific implementation, the mounting flanges 2010 at both ends of the bellows 200 are provided with countersunk holes 2012 on the side away from the upper fixing portion 40 and the lower fixing portion 41 of the bellows. The countersunk holes 2012 are connected with the through hole 2011. The diameter of the countersunk holes 2012 is larger than the diameter of the through hole 2011. The upper fixing portion 40 and the lower fixing portion 41 of the bellows respectively pass through the countersunk holes 2012 on the mounting flanges 2010 at both ends of the bellows 200 and extend out of the countersunk holes 2012. The parts of the upper fixing portion 40 and the lower fixing portion 41 of the bellows extending out of the countersunk holes 2012 are used to be connected and fixed to the mounting position. The retaining ring 50 on the upper fixing part 40 of the bellows auxiliary installation device is accommodated in the countersunk hole 2012 of the mounting flange 2010 at one end of the bellows 200, and the retaining ring 50 on the lower fixing part 41 of the bellows is accommodated in the countersunk hole 2012 of the mounting flange 2010 at one end of the bellows 200. The outer diameter of the retaining ring 50 is designed to be smaller than the diameter of the through hole 2011, so that the retaining ring 50 is stopped at the edge of the through hole 2011 in the countersunk hole 2012. When disassembling the bellows 200, taking the threaded connection between the upper fixing part 40 and the lower fixing part 41 of the bellows and the installation part as an example, in the process of disconnecting the upper fixing part 40 and the lower fixing part 41 of the bellows from the installation part, the upper fixing part 40 of the bellows and the second fixing part are loosened and gradually move away from the installation part. Since the edge of the through hole 2011 blocks the retaining ring 50, the retaining ring 50 fixes the axial position of the installation part and the upper fixing part 40 of the bellows, and the retaining ring 50 in the counterbore 2012 moves with the movement of the upper fixing part 40 and the lower fixing part 41 of the bellows. The retaining ring 50 generates a thrust on the edge of the through hole 2011, and drives the installation flange 2010 to move while loosening the upper fixing part 40 and the lower fixing part 41 of the bellows. In actual application scenarios of the bellows 200, such as when the bellows 200 is used in a semiconductor reaction chamber, the mounting flanges 2010 at both ends of the bellows 200 are easily adhered to the mounting portion of the semiconductor reaction chamber, and the retaining ring 50 can automatically separate the adhered mounting flanges 2010 from the mounting portion, eliminating the operation of adhesively separating the mounting flanges 2010 from the mounting portion, making the disassembly of the bellows 200 more convenient.

[0042] The bellows in this embodiment uses the bellows auxiliary installation device provided by the present invention, so the installation difficulty is reduced and the installation is more convenient and quick.
