Detailed Implementation

[0044] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0045] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0047] This utility model provides a gas cylinder protection ring and a gas cylinder assembly having the gas cylinder protection ring. The gas cylinder protection ring not only has high strength but also light weight. The specific solution is described through the following embodiments.

[0048] The gas cylinder assembly includes a gas cylinder, valves, fittings, and a gas cylinder protective ring 100.

[0049] The gas cylinder can be a vertical or horizontal cylinder; it can be an industrial Dewar flask or an LNG (Liquefied Natural Gas) vehicle-mounted cylinder, etc. This embodiment uses an LNG vehicle-mounted cylinder as an example for illustration.

[0050] The valve, fittings, and cylinder protection ring 100 all protrude from the same end of the cylinder. The cylinder protection ring 100 surrounds the valve and fittings to protect them. Specifically, the cylinder protection ring 100 is fixedly connected to the end of the cylinder and forms a receiving cavity with the end of the cylinder, in which the valve and fittings are housed. When the end of the cylinder receives external impact or collision, the cylinder protection ring 100 can effectively mitigate the impact force and prevent direct damage to the valve and fittings.

[0051] Please see Figure 1 and Figure 2 The gas cylinder protection ring 100 includes a metal body 10. One end of the metal body 10 is used to connect to the end of the gas cylinder. The metal body 10 has a cylindrical structure. This means that along the axial direction of the gas cylinder, the metal body 10 has a certain width, and this width exceeds the valves and fittings located on the top of the gas cylinder, thereby effectively protecting the valves and fittings.

[0052] It should be noted that the metal body 10 is made of metal, such as steel or aluminum alloy. Compared with other materials, such as plastic, it has higher strength and impact resistance, and can effectively withstand damage caused by external impacts, compression or gas cylinder drops, thereby better protecting the gas cylinder valve and fittings.

[0053] In some embodiments, the metal body 10 includes a connecting ring 11. The outer contour of the connecting ring 11 is approximately circular. The diameter of the connecting ring 11 is 100mm to 900mm, and can be set according to actual needs, as long as the valve and fittings at the top of the gas cylinder are located inside the connecting ring 11.

[0054] One end of the connecting ring 11 has an opening. An operator can pass through this opening to enter the interior of the connecting ring 11. The opening facilitates the installation of the metal body 10.

[0055] In some embodiments, a through hole 111 is provided on the connecting ring 11 in the metal body 10. The valve includes a safety valve that can protect the gas cylinder by relieving pressure. The fitting includes a discharge pipe, one end of which is connected to the safety valve, and the other end passes through the through hole 111 and is located outside the connecting ring 11. Therefore, the pressure released from the gas cylinder can be discharged to the outside of the gas cylinder assembly through this discharge pipe.

[0056] In some embodiments, the connecting ring 11 in the metal body 10 is also provided with a fixing hole 112. The fixing hole 112 may be elongated. The fixing hole 112 is located close to the through hole 111 and is used to install a pipe clamp for fixing the discharge pipe.

[0057] In some embodiments, a handrail hole 113 is provided on the connecting ring 11 in the metal body 10. The operator's hand can move the gas cylinder by holding onto the handrail hole 113. Alternatively, the handrail hole 113 can also be used in conjunction with other fixing devices, such as straps, to ensure that the gas cylinder remains stable during transfer, transportation, etc., and to prevent shaking.

[0058] It should be noted that the through hole 111, the fixing hole 112, and the armrest hole 113 may all include a rounded chamfer, thereby effectively reducing concentration and ensuring the strength of the connecting ring 11.

[0059] The gas cylinder protection ring 100 includes reinforcing ribs 20. The reinforcing ribs 20 are disposed on the metal body 10 and are used to enhance the strength of the metal body 10, thereby improving the rigidity and resistance to external pressure of the gas cylinder protection ring 100.

[0060] Specifically, the reinforcing rib 20 includes a reinforcing rib 20 disposed on the surface of the connecting ring 11 in the metal body 10. The reinforcing rib 20 may be disposed along the circumference of the connecting ring 11; or, the reinforcing rib 20 may be disposed along the axial direction of the connecting ring 11; or the connecting ring 11 may have reinforcing ribs 20 in both the circumferential and axial directions.

[0061] Furthermore, the extension direction of the reinforcing rib 20 can be the same as the circumferential direction of the connecting ring 11; or, the extension direction of the reinforcing rib 20 can be the same as the axial direction of the connecting ring 11, etc. The specific extension direction of the reinforcing rib 20 can be set according to actual needs and is not limited here. This specification uses the extension direction of the reinforcing rib 20 being the same as the circumferential direction and / or the axial direction of the connecting ring 11 as an example for explanation. Moreover, for ease of description, the reinforcing rib 20 whose extension direction is the same as the axial direction of the connecting ring 11 is defined as the first reinforcing rib 21, and the reinforcing rib 20 whose extension direction is the same as the circumferential direction of the connecting ring 11 is defined as the second reinforcing rib 22.

[0062] Understandably, there are multiple ways to set the reinforcing rib 20.

[0063] For example, Figure 2 In the embodiment of the gas cylinder protection ring 100 shown, the reinforcing rib 20 is provided with two first reinforcing ribs 21. The two first reinforcing ribs 21 are respectively disposed near the two ends of the corresponding opening of the connecting ring 11. Furthermore, in this embodiment, the length of the reinforcing rib 20 is consistent with the width of the connecting ring 11. This arrangement can enhance the strength of the end of the connecting ring 11 near the opening and reduce the impact of the opening on the strength of the connecting ring 11.

[0064] See Figure 3 , Figure 3The illustrated gas cylinder protection ring 100 embodiment includes a first reinforcing rib 21 and a second reinforcing rib 22. Two first reinforcing ribs 21 are provided, respectively located near the two ends of the connecting ring 11. Two second reinforcing ribs 22 are provided, respectively located on both sides of the connecting ring 11. One second reinforcing rib 22 is located near the connection point between the connecting ring 11 and the top of the gas cylinder, thereby reducing stress concentration at this connection point and improving the strength and stability of the connection between the connecting ring 11 and the top of the gas cylinder. The other second reinforcing rib 22 is located near the edge of the connecting ring 11 away from the top of the gas cylinder, thereby enhancing the strength of the connecting ring 11 on the edge away from the gas cylinder and effectively improving the deformation resistance of the connecting ring 11. Furthermore, the two ends of the first reinforcing rib 21 are connected to the ends of the second reinforcing rib 22, so that the two first reinforcing ribs 21 and the two second reinforcing ribs 22 form a closed ring, which can evenly distribute stress and is beneficial to the stability of the connecting ring 11 under external force. Furthermore, the connection between the first reinforcing rib 21 and the second reinforcing rib 22 can be formed with an arc-shaped chamfer, which can further reduce stress concentration and improve the durability and reliability of the connecting ring 11.

[0065] See Figure 4 , Figure 4 The gas cylinder protection ring 100 embodiment shown also includes a first reinforcing rib 21 and a second reinforcing rib 22. It is consistent with... Figure 3 The first reinforcing rib 21 and the second reinforcing rib 22 shown differ in their arrangement. The number of first reinforcing ribs 21 is greater than two; multiple first reinforcing ribs 21 are spaced apart along the circumferential direction of the connecting ring 11, and both ends of each first reinforcing rib 21 are connected to a second reinforcing rib 22. The arrangement of multiple first reinforcing ribs 21 helps to further improve the structural strength of the connecting ring 11. Specifically, the two first reinforcing ribs 21 and the second reinforcing ribs 22 located on both sides of the connecting ring 11 enclose a reinforced area, within which the through hole 111, the fixing hole 112, and the handrail hole 113 are located. This arrangement effectively reduces the impact on the strength of the connecting ring 11 caused by the openings, thus extending the service life of the connecting ring 11.

[0066] See Figure 5 , Figure 5 The gas cylinder protection ring 100 embodiment shown also includes a first reinforcing rib 21 and a second reinforcing rib 22. It is consistent with... Figure 4The first reinforcing rib 21 and the second reinforcing rib 22 shown differ in their arrangement. The number of first reinforcing ribs 21 is reduced, while a second reinforcing rib 22 is added. The added second reinforcing rib 22 is located in the middle of the connecting ring 11, and the through hole 111, fixing hole 112, and armrest hole 113 are located in the extending direction of the second reinforcing rib 22. This means that the sides corresponding to the through hole 111, fixing hole 112, and armrest hole 113 are connected to the second reinforcing rib 22. This arrangement prevents stress concentration at the sides corresponding to the through hole 111, fixing hole 112, and armrest hole 113, ensuring the connecting ring 11's resistance to external pressure.

[0067] In other embodiments, the sides corresponding to the through hole 111, the fixing hole 112, and the armrest hole 113 may also be connected to the first reinforcing rib 21. Alternatively, the sides corresponding to the through hole 111, the fixing hole 112, and the armrest hole 113 may be connected to both the first reinforcing rib 21 and the second reinforcing rib 22 simultaneously.

[0068] In some embodiments, the reinforcing rib 20 protrudes from the surface of the metal body 10. Alternatively, the reinforcing rib 20 is recessed from the surface of the metal body 10. See specifically... Figure 6 to Figure 8 It can be seen that the reinforcing rib 20 protrudes from the surface of the metal body 10. See also Figure 9 to Figure 11 It can be seen that the reinforcing rib 20 is recessed relative to the surface of the metal body 10.

[0069] It should be noted that some sections of the reinforcing rib 20 may protrude from the surface of the metal body 10, while others may be recessed from the surface of the metal body 10. Alternatively, among the multiple reinforcing ribs 20 disposed on the same connecting ring 11, some reinforcing ribs 20 may protrude from the surface of the metal body 10, while others may be recessed from the surface of the metal body 10.

[0070] also, Figure 8 and Figure 11 The cross-section of the reinforcing rib 20 shown is arc-shaped. In other embodiments, the cross-section of the reinforcing rib 20 can also be semi-circular, elliptical, rectangular, square, etc., depending on actual needs. It should be noted that the cross-sectional shapes of multiple reinforcing ribs 20 can be the same or different.

[0071] Alternatively, the reinforcing rib 20 can be provided on the outer wall of the connecting ring 11; or, provided on the inner wall of the connecting ring 11; or, the reinforcing rib 20 can be provided on both the outer wall and the inner wall of the connecting ring 11.

[0072] It should be noted that the length of the reinforcing rib 20 is also not limited. For example, the length of the first reinforcing rib 21 can be... Figure 2The width of the second reinforcing rib 22 shown is the same as that of the connecting ring 11, but it can also be shorter than the width of the connecting ring 11. The length of the second reinforcing rib 22 can be... Figure 3 and Figure 4 The form of a full circle can also be used as Figure 5 The stiffener 20 is not a complete circle interrupted by a hole. In other embodiments, the stiffener 20 may also be a structure interrupted by a slot.

[0073] In some embodiments, the reinforcing rib 20 can be welded to the metal body 10. Alternatively, the reinforcing rib 20 and the metal body 10 can be integrally formed, for example, by stamping, roll forming, or other methods.

[0074] The wall thickness of the metal body 10 in this application is 0.5mm to 2.5mm. Compared with the 3mm wall thickness of the main body in the gas cylinder protection ring in the prior art, the wall thickness of the metal body 10 is significantly reduced, thereby effectively reducing the weight of the gas cylinder protection ring 100.

[0075] The thickness of the reinforcing rib 20 provided on the metal body 10 is 0.5mm to 10mm. It is understood that when the reinforcing rib 20 is recessed relative to the surface of the metal body 10, the thickness of the reinforcing rib 20, i.e., the depth of the recess, must be less than the wall thickness of the metal body 10. However, when the reinforcing rib 20 protrudes relative to the surface of the metal body 10, there is no restriction, and the thickness of the reinforcing rib 20 is 0.5mm to 10mm, for example, 0.5mm, 3mm, 5mm, etc., which can be set according to actual needs and are not limited here. Furthermore, it should be noted that the thickness of the reinforcing rib 20 provided on the metal body 10 can increase as the diameter of the connecting ring 11 in the metal body 10 increases, in order to further improve the rigidity of the metal body 10. Correspondingly,

[0076] Please see Figure 1 The gas cylinder protection ring 100 includes a cover plate 30. The end of the metal body 10 furthest from the top of the gas cylinder is the connecting end. The cover plate 30 is disposed on the connecting end and is used to cover most of the pipes and valves, providing dust protection. Simultaneously, the cover plate 30 can also resist external impacts along the gas cylinder's axis to a certain extent. The cover plate 30, in conjunction with the metal body 10, provides comprehensive protection for the pipes and valves located on the top of the gas cylinder. In some embodiments, the cover plate 30 is a metal plate to enhance its strength and improve its impact resistance.

[0077] The cover plate 30 is detachably installed on the connecting end of the metal body 10, thereby facilitating the operator to inspect and disassemble the valves and fittings located at the end of the gas cylinder.

[0078] It should be noted that the detachable connection between the cover plate 30 and the metal body 10 can be screwed, snap-fit, etc., and can be set according to actual needs.

[0079] Specifically, in this embodiment, the detachable connection between the cover plate 30 and the metal body 10 is a screw connection. Specifically, the connecting end of the metal body 10 is provided with a plurality of connectors 50 spaced apart along its circumferential direction, each connector 50 being positioned towards the center of the metal body 10. Each connector 50 has a first connecting hole. The cover plate 30 has a second connecting hole. Each first connecting hole and each second connecting hole are opposite each other, allowing the fastener 60 to pass through the first and second connecting holes respectively, thereby achieving the connection between the cover plate 30 and the metal body 10.

[0080] In some embodiments, the fastener 60 may be a combination of a wing nut and a screw, allowing the operator to install and remove the fastener 60 without the need for external tools. Further, the cover plate 30 is connected to the connecting ring 11 in the metal body 10. The cover plate 30 is generally circular. The diameter of the cover plate 30 is 90mm to 890mm. The diameter of the cover plate 30 is smaller than the diameter of the connecting ring 11. For example, if the diameter of the connecting ring 11 is 100mm, the diameter of the cover plate 30 can be 90mm, 95mm, etc.; or if the diameter of the connecting ring 11 is 150mm, the diameter of the cover plate 30 can be 140mm, 142mm, etc.; or if the diameter of the connecting ring 11 is 900mm, the diameter of the cover plate 30 can be 880mm, 890mm, etc.

[0081] In some embodiments, the cover plate 30 has an observation hole 31. The gas cylinder includes a pressure gauge. The observation hole 31 is positioned opposite the pressure gauge. Therefore, the operator can view the pressure gauge through the observation hole 31 to check the pressure of the gas cylinder in a timely manner.

[0082] In some embodiments, the cover plate 30 has a first operating hole 32. The first operating hole 32 allows a person's hand to pass through. The valve includes a vent valve. The first operating hole 32 is disposed opposite to the vent valve. Therefore, an operator can operate the vent valve through the first operating hole 32 to control the pressure inside the gas cylinder.

[0083] In some embodiments, the cover plate 30 has a second operating hole 33. The second operating hole 33 allows a person's hand to pass through. The valve includes a liquid outlet valve, and the second operating hole 33 is disposed opposite to the liquid outlet valve. Therefore, the operator can operate the liquid outlet valve through the second operating hole 33 to control the supply of the medium loaded in the gas cylinder.

[0084] In some embodiments, the cover plate 30 has a third operating hole 34. The third operating hole 34 allows a person's hand to pass through. The valve includes a pressure boosting valve. The fitting includes a pressure boosting line. The third operating hole 34 is disposed opposite to the pressure boosting valve. Therefore, an operator can operate the pressure boosting valve through the third operating hole 34 to control the pressure boosting line.

[0085] It is understandable that the observation hole 31, the first operating hole 32, the second operating hole 33 and the third operating hole 34 on the cover plate 30 allow the operator to view and operate the corresponding instruments and valves without disassembling the cover plate 30.

[0086] In some embodiments, the cover plate 30 is also provided with reinforcing ribs 20 to improve the strength of the cover plate 30. Since the strength of the cover plate 30 is enhanced by the reinforcing ribs 20, the wall thickness of the cover plate 30 can be reduced, thereby reducing the weight of the cover plate 30, which further helps to reduce the overall weight of the gas cylinder protection ring 100.

[0087] Please see Figure 12 and Figure 13 The reinforcing rib 20 provided on the cover plate 30 is the third reinforcing rib 23. The third reinforcing rib 23 is provided on the surface of the cover plate 30 away from the valve and pipe fitting. The third reinforcing rib 23 is provided along the edge of the cover plate 30 to enhance the edge strength of the cover plate 30 and prevent the cover plate 30 from deforming due to the opening of the first connecting hole. The third reinforcing rib 23 is a closed ring, which can effectively reduce stress concentration and help improve the overall strength of the cover plate 30.

[0088] In other embodiments, the third reinforcing rib 23 may be provided on the surface of the cover plate 30 near the valve or pipe fitting; or the third reinforcing rib 23 may be provided on both sides of the cover plate 30. In addition, in other embodiments, the number, extension direction, cross-sectional shape, and whether the third reinforcing rib 23 protrudes or is recessed relative to the surface of the cover plate 30 may be provided according to actual needs, and no restrictions are imposed here.

[0089] The third reinforcing rib 23 can be welded to the cover plate 30. Alternatively, the reinforcing rib 20 and the cover plate 30 can be integrally formed, for example, by stamping or roll forming.

[0090] The wall thickness of the cover plate 30 in this application is 0.5mm to 2mm. In particular, when the wall thickness of the cover plate 30 is less than 2mm, the weight of the cover plate 30 can be reduced compared to the cover plate in the prior art, which usually has a wall thickness of 2mm, thereby further reducing the overall weight of the gas cylinder protection ring 100.

[0091] The thickness of the third reinforcing rib 23 is 0.5mm to 10mm. It is understood that when the third reinforcing rib 23 is recessed relative to the surface of the cover plate 30, the thickness of the third reinforcing rib 23, which is the depth of the recess, must be less than the wall thickness of the cover plate 30. However, when the reinforcing rib 23 protrudes relative to the cover plate 30, there are no restrictions, and the thickness of the third reinforcing rib 23 can be 0.5mm to 10mm, for example, 0.5mm, 3mm, 5mm, etc., which can be set according to actual needs and are not limited here.

[0092] In addition, the thickness of the third reinforcing rib 23 provided on the cover plate 30 can be increased as the diameter of the cover plate 30 increases, so as to improve the rigidity of the cover plate 30 and increase the strength of the cover plate 30.

[0093] See Figure 1 and Figure 2 In some embodiments, the cylinder protection ring 100 includes a dust cover 40. The valve includes a filling connector. The dust cover 40 covers the filling connector to prevent it from being contaminated by dust during daily use.

[0094] A dust cover 40 is mounted on the metal body 10. Specifically, the metal body 10 includes two extensions 12. Each extension 12 is connected to the end of the corresponding opening of the connecting ring 11. The extensions 12 extend outward toward the connecting ring 11. The dust cover 40 includes a panel (not shown). A filling connector is mounted on the panel. Both ends of the panel have bends, through which screws, bolts, and other fasteners can pass and connect to the extensions 12, thereby securing the panel.

[0095] Furthermore, along the axial direction of the gas cylinder, the width of the extension 12 is smaller than the width of the connecting ring 11, so that the metal body 10 forms a clearance space 70. The panel is located on the side of the extension 12 near the clearance space 70. This arrangement positions the entire panel away from the top of the gas cylinder, making it easier for the operator to operate the filling connector on the panel.

[0096] Furthermore, the provision of the clearance space 70 reduces the weight of the cylinder protection ring 100, contributing to its lightweight design. In some embodiments, some valves in the cylinder assembly are located within the clearance space 70, thus facilitating operation of the valves within the clearance space 70 by the operator.

[0097] The dust cover 40 includes a cover body 41. The cover body 41 is disposed on the side of the extension 12 away from the clearance space 70, covering the panel to effectively prevent dust from entering. Specifically, the metal body 10 includes a connecting plate (not shown), with its two ends respectively connected to the two extensions 12. Therefore, the connecting ring 11, the extensions 12, and the connecting plate form a closed ring. The cover body 41 includes a straight section 411 and a bent section 412. The straight section 411 is disposed opposite to the panel. The side of the straight section 411 away from the connecting ring 11 is hinged to the connecting plate. The two ends of the straight section 411 are respectively provided with bent sections 412, and the bent sections 412 extend toward the clearance space 70. This arrangement ensures that the cover body 41 is tightly connected to the extensions 12 of the metal body 10, effectively preventing dust from entering the space between the two extensions 12.

[0098] The cover 41 includes a locking element disposed on the top of the bent section 412 near the connecting ring 11. An accessory adapted to the locking element is provided on the extension 12 of the connecting ring 11, thus securing the top of the cover 41 to the extension 12. Therefore, the operator can open the cover 41 simply by unlocking the locking element or accessory and using the filling connector on the panel. Furthermore, since the straight section 411 is hinged to the connecting plate on the side away from the connecting ring 11, the cover 41 is prevented from falling off.

[0099] The gas cylinder protection ring 100 in this application includes a metal body 10, a cover plate 30, and reinforcing ribs 20. Both the metal body 10 and the cover plate 30 are provided with reinforcing ribs 20, thereby effectively improving the rigidity and resistance to external pressure of the gas cylinder protection ring 100. Furthermore, the wall thickness of the metal body 10 and the cover plate 30 can be reduced, thus meeting the requirement of reducing the weight of the gas cylinder protection ring 100.

[0100] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.
