Description

Technical Field

[0001] The invention belongs to the field of high-pressure gas cylinders, and in particular relates to a fixing device for a high-pressure gas storage cylinder group. Background Art

[0002] A high-pressure gas cylinder is a container for storing high-pressure gas and is widely used in various fields. For example, high-pressure gas cylinders are used in the medical, industrial and other fields to provide necessary gas supply for various fields. Therefore, the application of high-pressure gas cylinders is relatively common, and the demand is often large during application. Therefore, it is necessary to concentrate the high-pressure gas cylinders for easy use and subsequent maintenance; currently, the fixing method of the gas cylinder group is usually horizontal, and the bottle body of the high-pressure gas cylinder is fixed with a clamp. Therefore, when the gas cylinders are stacked, not only will the gas cylinders themselves occupy a certain space, but the clamps used for fixing will also occupy a certain space, thereby expanding the gap between the gas cylinders, resulting in a low effective volume ratio in the area used to place the gas cylinders. Summary of the invention

[0003] In view of the above-mentioned deficiencies, the present invention provides a fixing device for a high-pressure gas storage cylinder group, which reduces the gap between the cylinders and improves the volume ratio of the space by changing the fixing method of the cylinders.

[0004] The present invention is achieved through the following technical solutions:

[0005] A fixing device for a high-pressure gas storage cylinder group, the fixing device comprising a frame, a first cross beam arranged at the bottom end of the frame, and a second cross beam arranged at the top end of the frame, a receiving cavity for receiving a plurality of gas cylinders is formed in the frame, each gas cylinder is placed in the receiving cavity along a vertical direction, and a spacing between adjacent gas cylinders along an extension direction of the first cross beam or the second cross beam is no more than 20 cm; the fixing device further comprises a plurality of supporting parts arranged at the first cross beam, each gas cylinder corresponds to a supporting part, and when the gas cylinder is placed in the receiving cavity, the bottom end of the gas cylinder abuts against the supporting part; the fixing device further comprises a plurality of fixing parts arranged at the second cross beam, and a fixing part located at the second cross beam is arranged on the upper side of each supporting part, and when the gas cylinder is placed in the receiving cavity, the top end of the gas cylinder is fixed to the fixing part. By placing the gas cylinders vertically, the arrangement of the gas cylinders will change compared to horizontal placement. Therefore, when fixing the gas cylinders, although the two ends of the gas cylinders are also limited, the limiting method can be through the limitation in the vertical direction, so when fixing, no additional horizontal space will be occupied, thereby shortening the distance between adjacent gas cylinders, so that the spacing in the extension direction of the first beam or the second beam will not be greater than 20cm. After the spacing between adjacent gas cylinders is reduced, the number of gas cylinders that can be stored in the same space will also increase accordingly. Compared with horizontal placement of gas cylinders, the occupied area of ​​the gas cylinders will not be expanded when fixing the gas cylinders, thereby improving the effective utilization of space when the gas cylinders are stacked.

[0006] Furthermore, the fixing device also includes a limiting portion corresponding to each accommodating cavity, and the limiting portion includes a limiting plate arranged along the installation direction of the gas cylinder. When the gas cylinder is placed in the accommodating cavity, the gas cylinder abuts against the corresponding limiting plate. Since the gas cylinder is placed vertically when placed, and the height of the gas cylinder in the present application is relatively high, the gas cylinder can be limited by the support portion when placed vertically, thereby ensuring the accuracy of the gas cylinder when placed. At the same time, by setting the limiting portion, the limiting portion includes a limiting plate. When the gas cylinder is placed, the limiting plate can limit the installation of the gas cylinder. Since the extension direction of the limiting plate is the installation direction of the gas cylinder, when the gas cylinder is installed, the limiting plate can ensure the accuracy of the gas cylinder when placed, so that the gas cylinder can be accurately placed at the support portion.

[0007] Furthermore, the limiting part also includes a pulley arranged on the second crossbeam, a suspension rope wound around the pulley, and a bearing member located on the upper side of the support part, the weight of the bearing member is less than the limiting plate, one end of the suspension rope is connected to the bearing member, and the other end is connected to the limiting plate. The bearing member and the limiting plate are respectively located on both sides of the pulley, so that the bearing member and the limiting plate can move toward each other, that is, when the bearing member moves downward, the limiting plate can be driven to move upward, and vice versa; and since the weight of the bearing member is relatively light, the limiting plate will be located below the bearing member under normal conditions, and when the gas cylinder is placed at the support part, since the bearing member is located on the upper side of the support part, the gas cylinder will drive the bearing member to move toward the support part when placed, and since the weight of the gas cylinder is much greater than the weight of the limiting plate, the limiting plate will be driven to move upward, that is, move toward the gas cylinder, and then limit the gas cylinder, so that the gas cylinder is limited in the middle and rear sections of the placement of the gas cylinder, so as to ensure that the gas cylinder can be accurately placed at the support part.

[0008] Furthermore, the distance between the first crossbeam and the second crossbeam in the vertical direction is H, the height of the limit plate is h, and h<H / 2. During the placement of the gas cylinder, space can be left for the movement of the limit plate, thereby preventing the limit plate from abutting against the first crossbeam, affecting the movement of the bearing member driven by the gas cylinder, and causing the gas cylinder to be unable to be normally placed on the support portion.

[0009] Furthermore, each gas cylinder is provided with a shaft sleeve that abuts against the fixing part. The fixing part is used to fix the top of the gas cylinder, so when the shaft sleeve is provided, it is provided at the bottle mouth on the upper side of the gas cylinder, and is connected to the fixing part through the shaft sleeve, so that when the length of the gas cylinder changes due to the pressing or depressurization of the gas cylinder, the normal use of the gas cylinder will not be affected due to the fixing constraint of the gas cylinder by the fixing part.

[0010] Furthermore, the extension direction of the first crossbeam is perpendicular to the extension direction of the second crossbeam. The first crossbeam and the second crossbeam have different extension directions, so that when the corresponding support part and the fixing part are set, the support part and the second crossbeam where the fixing part is located can be staggered in the vertical direction. When the gas cylinder is placed on the corresponding support part, the second crossbeam where the fixing part corresponding to the support part is located will not hinder the placement of the gas cylinder. After the gas cylinder is fixed to the support part, the top of the gas cylinder can be fixed by the fixing part. At the same time, since the support part and the second crossbeam where the corresponding fixing part is located are staggered, the fixing part is set on one side of the second crossbeam, so that the corresponding support part and the fixing part can be corresponded in the vertical direction, so that after the gas cylinder is placed vertically, the bottom and top of the gas cylinder can be fixed.

[0011] Furthermore, the support portion includes a positioning member corresponding to the bottom end of the gas cylinder, and a support assembly fixed to the upper side of the positioning member, and the support assembly is formed with a support hole that is engaged with the bottom end of the gas cylinder. The positioning member is located at the lower side of the support assembly, so when the gas cylinder is placed, the bottom end of the gas cylinder will eventually fall into the positioning member, and the positioning member can also play a positioning role when the gas cylinder is placed, so that the position of the gas cylinder is more accurate when placed. Since the present application can shorten the distance between adjacent gas cylinders, the placement position of the gas cylinder is more accurate, and it can also avoid that the gas cylinder will not collide with adjacent gas cylinders after placement. The support assembly is located on the upper side of the positioning member. When the gas cylinder is placed, the thinner bottom end of the gas cylinder is located at the positioning member, and the size of the part of the gas cylinder that cooperates with the support assembly will be larger than the part in the positioning member, thereby increasing the contact area between the positioning member and the gas cylinder, better supporting the gas cylinder, and preventing the gas cylinder from shaking.

[0012] Furthermore, a clamping piece is provided at the support hole to abut against the gas cylinder in the circumferential direction. The clamping piece abuts against the gas cylinder in the circumferential direction, so the gas cylinder can be limited in the circumferential direction by the clamping piece, thereby preventing the gas cylinder from rotating after being placed, which affects the stability of the gas cylinder.

[0013] Furthermore, the support assembly includes a first support member and a second support member that are separately arranged, and a locking member that fixes the first support member and the second support member, and the first support member and the second support member are enclosed to form a support hole. Since the support hole is formed at the support assembly, the gas cylinder is enclosed, and the gas cylinder is fixed and supported in the circumferential direction. At the same time, the first support member and the second support member are separately arranged, so the first support member and the second support member can fix the gas cylinder after the gas cylinder is placed in place, that is, after the bottom end of the gas cylinder is extended into the positioning member, the first support member and the second support member are enclosed to the gas cylinder, so that the gas cylinder will not be affected during the placement of the gas cylinder through the structure of the separate arrangement, and the first support member and the second support member are assembled after being placed in place. After the first support member and the second support member enclose the gas cylinder, the first support member and the second support member are fixed and locked by the locking member to prevent the first support member and the second support member from separating, thereby achieving better fixation of the gas cylinder.

[0014] Furthermore, the support assembly also includes a first fixing member for fixing the first support member and the positioning member, and a second fixing member for fixing the second support member and the positioning member, and the extension direction of the first fixing member and the second fixing member are both perpendicular to the extension direction of the locking member. The first fixing member and the second fixing member can be respectively fixed to the positioning member, thereby improving the integrity between the first support member, the second support member and the positioning member. At the same time, when the first fixing member and the second fixing member are fixed, the extension direction of both is perpendicular to the extension direction of the locking member, that is, the first fixing member and the second fixing member fix the first support member and the second support member in the vertical direction, and the locking member fixes in the horizontal direction, so that the first fixing member, the second fixing member and the locking member will not affect each other, and the fixing effect is better.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that the directional terms such as left, right, up, down, front and back in the embodiments of the present invention are merely relative concepts or are based on the normal use state of the product, that is, the direction of movement of the product, and should not be considered as limiting.

[0026] In addition, it should be noted that the dynamic terms such as "relative motion" mentioned in the embodiments of the present invention refer not only to changes in position, but also to movements such as rotation and rolling in which there is no relative change in position but a change in state.

[0027] Finally, it should be noted that when a component is referred to as being "located" or "set on" another component, it can be on the other component or there can be an intermediate component at the same time. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there can be an intermediate component at the same time.

[0028] like Figures 1 to 6A fixing device for a high-pressure gas storage cylinder group is shown, the fixing device comprises a frame 1, a first crossbeam 2 arranged at the bottom end of the frame 1, and a second crossbeam 3 arranged at the top end of the frame 1. A receiving cavity for accommodating a plurality of gas cylinders 4 is formed in the frame 1, and each gas cylinder 4 is placed in the receiving cavity along the vertical direction. Along the extension direction of the first crossbeam 2 or the second crossbeam 3, the spacing between adjacent gas cylinders 4 is not greater than 20 cm; for the present application, when storing the gas cylinders 4, the gas cylinders 4 are placed vertically, and the arrangement of the gas cylinders 4 will also change compared with the horizontal placement, so when the gas cylinders 4 are placed When fixing, although the two ends of the gas cylinder 4 are also limited, the limiting method can be through the limitation in the vertical direction, so when fixing, no additional horizontal space will be occupied, thereby shortening the distance between adjacent gas cylinders 4, so that the spacing in the extension direction of the first beam 2 or the second beam 3 will not be greater than 20cm. After the spacing between adjacent gas cylinders 4 is reduced, the number of gas cylinders 4 that can be stored in the same space will also increase accordingly. Compared with the horizontal placement of the gas cylinder 4, the occupied area of ​​the gas cylinder 4 will not be expanded when the gas cylinder 4 is fixed, thereby improving the effective utilization rate of the space when the gas cylinder 4 is stacked.

[0029] Specifically, the fixing device also includes a plurality of supporting parts arranged at the first cross beam 2, each gas cylinder 4 corresponds to a supporting part, and when the gas cylinder 4 is placed in the accommodating cavity, the bottom end of the gas cylinder 4 abuts against the supporting part; the fixing device also includes a plurality of fixing parts 6 arranged at the second cross beam 3, and the upper side of each supporting part is provided with a fixing part 6 located at the second cross beam 3, and when the gas cylinder 4 is placed in the accommodating cavity, the top end of the gas cylinder 4 is fixed to the fixing part 6; through the supporting part and the fixing part 6, the bottom end and the top end of the gas cylinder 4 can be fixed, so as to limit the gas cylinder 4 in the installation cavity, and prevent the gas cylinder 4 from being stuck in the installation cavity. 4 shakes to ensure the safety and stability of the gas cylinders 4 when they are stacked, wherein the support portion is arranged at the first cross beam 2 at the bottom, so after the gas cylinder 4 is placed at the support portion, the support portion can not only play a supporting and fixing role, but also has a limiting function to ensure the stability of the gas cylinder 4 when it is placed vertically, and the fixing portion 6 is located at the second cross beam 3 at the top, when the gas cylinder 4 is snapped into the corresponding support portion, the support portion will bear the dead weight of the gas cylinder 4 and fix the gas cylinder 4, and at this time, the top of the gas cylinder 4 is fixed by the fixing portion 6, so that the gas cylinder 4 is fixed in the accommodating cavity.

[0030] As a preferred embodiment of the present application, the support portion is located within the projection of the gas cylinder 4 along the vertical direction. Since the structure of the gas cylinder 4 is thin at both ends and thick in the middle, when the support portion fixes the bottom end of the gas cylinder 4, the width of the portion in contact with the gas cylinder 4 will also be relatively small, and the spacing between adjacent gas cylinders 4 is the spacing between the middle parts of the gas cylinders 4. Therefore, when the gas cylinder 4 is fixed by the support portion, the size of the support portion will not be larger than the maximum size of the gas cylinder 4. Therefore, when the gas cylinder 4 is installed, the number of gas cylinders 4 stacked is limited by the size of the gas cylinder 4 itself, and the support portion will not affect the installation of adjacent gas cylinders 4.

[0031] In the present application, the extension direction of the first crossbeam 2 is perpendicular to the extension direction of the second crossbeam 3; since the support portion and the fixing portion 6 are respectively arranged at the first crossbeam 2 and the second crossbeam 3, and the bottom end and the top end of the gas cylinder 4 are fixed respectively, the extension directions of the first crossbeam 2 and the second crossbeam 3 are different, so that when the corresponding support portion and the fixing portion 6 are arranged, the second crossbeam 3 where the support portion and the fixing portion 6 are located can be staggered in the vertical direction. When the gas cylinder 4 is placed on the corresponding support portion, the second crossbeam 3 where the fixing portion 6 corresponding to the support portion is located will not hinder the placement of the gas cylinder 4. After the gas cylinder 4 is fixed to the support portion, the top end of the gas cylinder 4 can be fixed by the fixing portion 6. At the same time, since the support portion and the second crossbeam 3 where the corresponding fixing portion 6 are located are staggered, the fixing portion 6 is arranged on one side of the second crossbeam 3, so that the corresponding support portion and the fixing portion 6 can be corresponded in the vertical direction, so that after the gas cylinder 4 is placed vertically, the bottom end and the top end of the gas cylinder 4 can be fixed.

[0032] In the present application, the fixing device also includes a limiting portion 7 corresponding to each accommodating cavity, and the limiting portion 7 includes a limiting plate 71 arranged along the installation direction of the gas cylinder 4. When the gas cylinder 4 is placed in the accommodating cavity, the gas cylinder 4 abuts against the corresponding limiting plate 71; since the gas cylinder 4 is placed vertically when placed, and the height of the gas cylinder 4 in the present application is relatively high, the gas cylinder 4 can be limited by the support portion when placed vertically, thereby ensuring the accuracy of the gas cylinder 4 when placed, and at the same time, by setting the limiting portion 7, the limiting portion 7 includes a limiting plate 71. When the gas cylinder 4 is placed, the limiting plate 71 can limit the installation of the gas cylinder 4. Since the extending direction of the limiting plate 71 is the installation direction of the gas cylinder 4, when the gas cylinder 4 is installed, the limiting plate 71 can ensure the accuracy of the gas cylinder 4 when placed, so that the gas cylinder 4 can be accurately placed at the support portion.

[0033] It can be understood that since the extension directions of the first crossbeam 2 and the second crossbeam 3 are perpendicular to each other, the second crossbeam 3 can not only support the fixing portion 6, but also serve as a partition, serving as a dividing line for adjacent gas cylinders 4 when they are placed, and also provides space for the installation of the limit plate 71. The limit plate 71 is arranged below the second crossbeam 3, which can not only play a limiting role, but also because the gas cylinder 4 will also fall from the second crossbeam 3 when placed, the limit plate 71 is located below the second crossbeam 3 and will not affect the placement of the gas cylinder 4.

[0034] As a preferred embodiment of the present application, the limiting portion 7 further includes a pulley 72 arranged on the second cross beam 3, a sling 73 wound around the pulley 72, and a bearing member 74 located on the upper side of the support portion, the weight of the bearing member 74 is less than the limiting plate 71, one end of the sling 73 is connected to the bearing member 74, and the other end is connected to the limiting plate 71; the bearing member 74 and the limiting plate 71 are respectively located on both sides of the pulley 72, so that the bearing member 74 and the limiting plate 71 can move towards each other, that is, when the bearing member 74 moves downward, it can drive the limiting plate 71 to move upward, and vice versa; Since the weight of the support member 74 is relatively light, the limit plate 71 will be located below the support member 74 under normal circumstances. When the gas cylinder 4 is placed on the support portion, since the support member 74 is located on the upper side of the support portion, the gas cylinder 4 will drive the support member 74 to move toward the support portion when placed. Since the weight of the gas cylinder 4 is much greater than the weight of the limit plate 71, the limit plate 71 will be driven to move upward, that is, move toward the gas cylinder 4, and limit the gas cylinder 4 accordingly, thereby limiting the gas cylinder 4 in the middle and rear section of the placement of the gas cylinder 4, thereby ensuring that the gas cylinder 4 can be accurately placed on the support portion.

[0035] Preferably, the distance between the first beam 2 and the second beam 3 in the vertical direction is H, and the height of the limit plate 71 is h, where h is less than H / 2. Since the limit plate 71 is connected to the support member 74 through the suspension rope 73, the support member 74 and the limit plate 71 can drive each other to achieve position change, and the height of the limit plate 71 is less than 1 / 2 of the height between the first beam 2 and the second beam 3. Therefore, during the placement of the gas cylinder 4, space can be left for the movement of the limit plate 71, thereby preventing the limit plate 71 from abutting against the first beam 2, affecting the movement of the support member 74 driven by the gas cylinder 4, and causing the gas cylinder 4 to be unable to be normally placed on the support portion.

[0036] In the present application, when it is necessary to place the gas cylinder 4, the gas cylinder 4 can be moved into the accommodating cavity by hoisting. Since the structure of the gas cylinder 4 is thin at both ends and thick in the middle, the mouth of the gas cylinder 4 can be hoisted. At the same time, when the gas cylinder 4 is placed, it will also drive the supporting member 74 to move toward the support part and be fixed at the support part. Therefore, in order to ensure that the supporting member 74 does not affect the placement of the gas cylinder 4, the supporting member 74 can be selected as an annular structure, so that the supporting member 74 can be mounted on the bottom end of the gas cylinder 4. Alternatively, the supporting member 74 can also be selected as a solid structure. When the gas cylinder 4 drives the supporting member 74 to move to the support part, installation space can be reserved for the supporting member 74 at the support part, thereby preventing the supporting member 74 from affecting the normal placement of the gas cylinder 4.

[0037] In the present application, the support portion includes a positioning piece 51 corresponding to the bottom end of the gas cylinder 4, and a support assembly fixed to the upper side of the positioning piece 51, and the support assembly is formed with a support hole that is clamped with the bottom end of the gas cylinder 4; the positioning piece 51 is located at the lower side of the support assembly, so when the gas cylinder 4 is placed, the bottom end of the gas cylinder 4 will eventually fall into the positioning piece 51, and the positioning piece 51 can also play a positioning role when the gas cylinder 4 is placed, so that the position of the gas cylinder 4 is more accurate when placed. Since the present application can shorten the distance between adjacent gas cylinders 4, the placement position of the gas cylinder 4 is more accurate, and it can also avoid that the gas cylinder 4 will not collide with adjacent gas cylinders 4 after placement. The support assembly is located on the upper side of the positioning piece 51. When the gas cylinder 4 is placed, the thinner bottom end of the gas cylinder 4 is located at the positioning piece 51, and the size of the part of the gas cylinder 4 that cooperates with the support assembly will be larger than the part in the positioning piece 51, thereby increasing the contact area between the positioning piece 51 and the gas cylinder 4, better supporting the gas cylinder 4, and preventing the gas cylinder 4 from shaking.

[0038] As a preferred embodiment of the present application, the support assembly includes a first support member 52 and a second support member 53 which are separately arranged, and a locking member 54 for fixing the first support member 52 and the second support member 53. The first support member 52 and the second support member 53 are surrounded by a support hole. Since the support hole is formed at the support assembly, the gas cylinder 4 is surrounded, and the gas cylinder 4 is fixed and supported in the circumferential direction. At the same time, the first support member 52 and the second support member 53 are separately arranged, so the first support member 52 and the second support member 53 can be placed in place before the gas cylinder 4 is fixed and supported. 4 is fixed, that is, after the bottom end of the gas cylinder 4 extends into the positioning member 51, the first support member 52 and the second support member 53 are surrounded to the gas cylinder 4, so that the gas cylinder 4 will not be affected during the placement of the gas cylinder 4 through the structure of the split arrangement, and the first support member 52 and the second support member 53 are assembled after the gas cylinder 4 is placed in place. When the first support member 52 and the second support member 53 surround the gas cylinder 4, the first support member 52 and the second support member 53 are fixed and locked by the locking member 54 to prevent the first support member 52 and the second support member 53 from separating, thereby achieving better fixation of the gas cylinder 4.

[0039] Since the first support member 52 and the second support member 53 are separately arranged, when the gas cylinder 4 is placed, the first support member 52 and the second support are enclosed around the gas cylinder 4, so as to protect the gas cylinder 4 in the circumferential direction. As a preferred embodiment of the present application, the support assembly also includes a first fixing member for fixing the first support member 52 and the positioning member 51, and a second fixing member for fixing the second support member 53 and the positioning member 51. The extension directions of the first fixing member and the second fixing member are both perpendicular to the extension direction of the locking member 54. The first fixing member and the second fixing member can be respectively fixed to the first support member 52 and the second support member. The support member 52 and the second support member 53 are fixed to the positioning member 51, thereby improving the integrity between the first support member 52, the second support member 53 and the positioning member 51. At the same time, when fixed by the first fixing member and the second fixing member, the extension direction of both is perpendicular to the extension direction of the locking member 54, that is, the first fixing member and the second fixing member fix the first support member 52 and the second support member 53 in the vertical direction, and the locking member 54 is fixed in the horizontal direction, so that the first fixing member, the second fixing member and the locking member 54 will not affect each other, and the fixing effect is better.

[0040] Preferably, a clamping piece is provided at the support hole, which abuts against the gas cylinder 4 in the circumferential direction; the clamping piece abuts against the gas cylinder 4 in the circumferential direction, so the gas cylinder 4 can be limited in the circumferential direction by the clamping piece, thereby preventing the gas cylinder 4 from rotating after being placed, affecting the stability of the gas cylinder 4.

[0041] As an implementation mode of the above-mentioned embodiment, since the support hole is formed by the first support member 52 and the second support member 53, and when the gas cylinder 4 is placed, the gas cylinder 4 will be located on the inner side of the support hole, the clamping member can be set so that the clamping member is formed by the inner wall of the support hole, that is, the support hole formed by the first support member 52 and the second support member 53 is an elliptical hole or an irregular hole. When the first support member 52 and the second support member 53 are closed to limit the gas cylinder 4, the gas cylinder 4 will abut against the inner wall of the support hole. At the same time, since the shape of the support hole does not match the shape of the gas cylinder 4, when the gas cylinder 4 has a tendency to rotate, the gas cylinder 4 can be limited by the inner wall of the support hole to prevent the gas cylinder 4 from rotating.

[0042] As another implementation of the above embodiment, the clamping part can also be a protruding structure arranged at the supporting hole, and the positioning part is recessed to form a structure matching the inner wall of the gas cylinder. When the gas cylinder is placed, the inner wall of the gas cylinder 4 will abut against the clamping part, thereby achieving the limitation of the gas cylinder 4.

[0043] In the present application, each gas cylinder 4 is provided with a shaft sleeve 8 abutting against the fixing portion 6; the fixing portion 6 is used to fix the top end of the gas cylinder 4, so when the shaft sleeve 8 is set, it is set at the bottle mouth on the upper side of the gas cylinder 4, and is connected to the fixing portion 6 through the shaft sleeve 8. Therefore, when the gas cylinder 4 is pressed or depressurized to cause the length of the gas cylinder 4 to change, the normal use of the gas cylinder 4 will not be affected by the fixing constraint of the fixing portion 6 on the gas cylinder 4.

[0044] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
