Description

Technical Field

[0001] This utility model relates to the field of gas filling machine technology, and in particular to a gas cylinder support device. Background Technology

[0002] A gas filling machine is a mechanical device used to fill containers with gas (or liquefied gas) at a predetermined pressure and quantity. In the food industry, a gas filling machine includes a gas cylinder used to store and transport the gas. The gas cylinder is connected to a sparkling water machine via a pressure reducing valve, and the gas cylinder can introduce gases such as carbon dioxide into the sparkling water machine, which then produces a beverage with bubbles.

[0003] In existing technologies, gas cylinders are typically connected to sparkling water machines in two ways: 1. The gas cylinder is placed directly on the work platform, with the inlet of the pressure reducing valve connected to the cylinder and the outlet connected to the sparkling water machine. In this connection method, the gas cylinder is not secured and may tip over due to vibrations of the work platform, causing pressure reduction or gas supply failure. 2. The gas cylinder is directly fixed to the work platform using pipe clamps, with the inlet of the pressure reducing valve connected to the cylinder and the outlet connected to the sparkling water machine. In this connection method, when replacing or disassembling the gas cylinder, the operator needs to operate the cylinder with one hand and hold the pressure reducing valve with the other. Due to the large size of the gas cylinder, operating it with only one hand is very inconvenient and may cause the cylinder to fall off, leading to a safety accident. Utility Model Content

[0004] The purpose of this invention is to provide a gas cylinder support device that is safe and easy to replace.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A gas cylinder support device, comprising:

[0007] The mounting bracket is used for connection to an external structure;

[0008] The bracket is rotatably connected to the fixed frame via a rotary damper, which can fix the rotation angle of the bracket. The bracket is equipped with a pressure reducing valve, and the air inlet of the pressure reducing valve can be connected to a gas cylinder.

[0009] Preferably, the bracket includes a first limiting ring and a second limiting ring, wherein the first limiting ring can engage with the first end of the pressure reducing valve and the second limiting ring can engage with the second end of the pressure reducing valve.

[0010] Preferably, the second end is provided with a straight portion, and the second limiting ring includes a snap-fit ​​portion that abuts against the straight portion to prevent the pressure reducing valve from rotating around its own axis.

[0011] Preferably, both the first limiting ring and the second limiting ring are detachably connected to the bracket.

[0012] Preferably, the bracket further includes a first support plate, a first connecting plate, and a second support plate connected in sequence. The first connecting plate is rotatably connected to the fixed frame, the first limiting ring is connected to the first support plate, and the second limiting ring is connected to the second support plate.

[0013] Preferably, the fixing frame includes a first limiting member, which includes a first limiting part and a second limiting part spaced apart. The bracket has a first rotation limit position and a second rotation limit position. The first connecting plate is movable between the first limiting part and the second limiting part. When the bracket is located at the first rotation limit position, the first connecting plate abuts against the first limiting part. When the bracket is located at the second rotation limit position, the first connecting plate abuts against the second limiting part.

[0014] Preferably, the rotary damper includes a rotating shaft, a first connecting flange, and a second connecting flange. Both the first connecting flange and the second connecting flange are sleeved on the rotating shaft. One of the first connecting flange and the second connecting flange is fixedly connected to the rotating shaft, and the other is rotatably connected to the rotating shaft. The first connecting flange is connected to the fixed frame, and the second connecting flange is connected to the bracket.

[0015] Preferably, the first connecting flange is connected to the fixing bracket by screws, and the second connecting flange is connected to the bracket by screws.

[0016] Preferably, the fixing frame further includes a second connecting plate and a first fixing plate that are vertically connected, the second connecting plate being rotatably connected to the bracket, and the first fixing plate being able to be connected to the external structure.

[0017] Preferably, the fixing frame further includes a third connecting plate and a second fixing plate that are interconnected and arranged in parallel. The third connecting plate is rotatably connected to the bracket, and the second fixing plate can be connected to the external structure.

[0018] The beneficial effects of this utility model are:

[0019] This utility model proposes a gas cylinder support device, including a fixed frame and a bracket rotatably connected. The fixed frame is used to connect to an external structure, and a pressure reducing valve that can connect to the gas cylinder is fixedly installed on the bracket, thereby supporting and fixing the gas cylinder to prevent the gas cylinder from tipping over during operation and improving operational safety. In addition, a rotation damper is provided between the fixed frame and the bracket. The rotation damper can fix the rotation angle of the bracket and prevent the bracket from quickly returning to its original position due to gravity or inertia, which facilitates the disassembly and assembly of the gas cylinder. Specifically, when staff need to replace a gas cylinder, they only need to hold the cylinder with both hands and lift it so that the bracket and pressure reducing valve rotate relative to the fixed frame to a certain angle. At this time, the direction of the pressure reducing valve's air inlet moves with the rotation of the bracket. Then, the gas cylinder is rotated away from the pressure reducing valve. Under the action of the rotation damper, the bracket and pressure reducing valve still maintain a certain rotation angle with the fixed frame, that is, the direction of the pressure reducing valve's air inlet remains unchanged. Then, staff can install other gas cylinders onto the pressure reducing valve's air inlet. Throughout the entire process, staff only need to hold the gas cylinder and do not need to adjust the bracket to adjust the direction of the pressure reducing valve's air inlet, further improving operational safety and convenience.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] Reference Figures 1 to 5 This embodiment proposes a gas cylinder support device, including a fixed frame 1 and a support 2 rotatably connected. The fixed frame 1 is used to connect to an external structure, and a pressure reducing valve 3 that can connect to a gas cylinder 5 is fixedly installed on the support 2, thereby supporting and fixing the gas cylinder 5, preventing the gas cylinder 5 from tipping over during operation, and improving operational safety. Furthermore, the fixed frame 1 and the support 2 are rotatably connected by a rotary damper 4, which can fix the rotation angle of the support 2, preventing the support 2 from quickly returning to its original position due to gravity or inertia, facilitating the assembly and disassembly of the gas cylinder 5. The external structure can be a sparkling water machine, and the gas cylinder 5 can be directly connected to the sparkling water machine through the fixed frame 1, reducing space occupation.

[0033] Specifically, when staff need to replace gas cylinder 5, they only need to hold gas cylinder 5 with both hands and lift it so that the bracket 2 and pressure reducing valve 3 rotate relative to the fixed frame 1 to a certain angle. At this time, the orientation of the air inlet of pressure reducing valve 3 moves with the rotation of bracket 2. Then, screw gas cylinder 5 to disengage it from pressure reducing valve 3. Under the action of rotation damper 4, bracket 2 and pressure reducing valve 3 can still maintain a certain rotation angle with fixed frame 1, that is, the orientation of air inlet of pressure reducing valve 3 is still maintained. Then, staff can install other gas cylinders 5 onto the air inlet of pressure reducing valve 3. Throughout the process, staff only need to hold gas cylinder 5 and do not need to adjust bracket 2 to adjust the orientation of air inlet of pressure reducing valve 3, further improving the safety and convenience of operation.

[0034] Understandably, the fixed frame 1 is connected to the external structure, and the bracket 2 is rotatably connected to the fixed frame 1. The bracket 2 is fixedly equipped with a pressure reducing valve 3 that can connect to the gas cylinder 5. During normal operation, the bracket 2 and the fixed frame 1 are relatively fixed, and the gas cylinder 5 is in a hanging state under the action of gravity. The gas cylinder 5 is perpendicular to the ground, and the air inlet of the pressure reducing valve 3 faces the ground. When the staff needs to replace the gas cylinder 5, they can first lift the gas cylinder 5 so that the bracket 2 rotates relative to the fixed frame 1, so that the gas cylinder 5 is at a first angle to the ground. Then, the gas cylinder 5 is disassembled from the pressure reducing valve 3. At this time, the air inlet of the pressure reducing valve 3 is also at a first angle to the ground. Due to the rotation damper 4 between the bracket 2 and the fixed frame 1, the bracket 2 will not quickly return to the upright position under the action of gravity and inertia. That is, the air inlet of the pressure reducing valve 3 is still at a first angle to the ground. Thus, the staff can replace the gas cylinder 5 and connect it to the air inlet of the pressure reducing valve 3. It is worth noting that when the air inlet of the pressure reducing valve 3 is at a first angle to the ground, disassembling or installing the gas cylinder 5 is more ergonomic, reducing the burden on the worker's waist, avoiding the need to bend over or adopt an awkward posture when directly disassembling or installing the gas cylinder 5, and reducing the risk of injury.

[0035] Furthermore, due to the presence of the rotation damper 4, the damper 4 ensures the stable rotation of the support 2 during the lifting of the gas cylinder 5, thereby guaranteeing the smooth movement of the gas cylinder 5 and improving operational fluency. Preferably, the damping value of the rotation damper 4 is adjustable, allowing operators to pre-adjust the damping value according to the specific model of the gas cylinder 5, ensuring high safety and convenience even when the support 2 is used to fix different models of gas cylinders 5.

[0036] Furthermore, the bracket 2 includes a first limiting ring 21 and a second limiting ring 22. The first limiting ring 21 can engage with the first end 31 of the pressure reducing valve 3, and the second limiting ring 22 can engage with the second end 32 of the pressure reducing valve 3. The first limiting ring 21 and the second limiting ring 22 are arranged opposite to each other to engage the two ends of the pressure reducing valve 3 to fix the pressure reducing valve 3. Specifically, the inner ring of the first limiting ring 21 can wrap around the outside of the first end 31 of the pressure reducing valve 3, and the inner ring of the second limiting ring 22 can wrap around the outside of the second end 32 of the pressure reducing valve 3, thereby fixing the pressure reducing valve 3 to the bracket 2. In this embodiment, both the first limiting ring 21 and the second limiting ring 22 are unclosed rings. The first limiting ring 21 is provided with a first opening, and the second limiting ring 22 is provided with a second opening, which can reduce the weight of the bracket 2. The width of the first opening is smaller than the outer diameter of the first end 31 of the pressure reducing valve 3, and the width of the second opening is smaller than the outer diameter of the second end 32 of the pressure reducing valve 3, to prevent the pressure reducing valve 3 from falling out of the first opening or the second opening, which would cause the pressure reducing valve 3 to fail to be fixed. Of course, in other embodiments, the first limiting ring 21 and / or the second limiting ring 22 may also be closed rings, which is not limited here.

[0037] The method of fixing the pressure reducing valve 3 by using the first limiting ring 21 and the second limiting ring 22 is more convenient and has a lower manufacturing cost compared to traditional bolt fixing or simple welding fixing.

[0038] Additionally, refer to Figure 4 To prevent the pressure reducing valve 3 from rotating when fixed on the bracket 2, the second limiting ring 22 includes a locking portion 221. The second end 32 of the pressure reducing valve 3 has a straight portion 321, and the locking portion 221 abuts against the straight portion 321 to prevent rotation of the pressure reducing valve 3. Specifically, the locking portion 221 protrudes from the inner ring of the second limiting ring 22. When the inner ring of the second limiting ring 22 covers the outside of the second end 32 of the pressure reducing valve 3, the locking portion 221 abuts against the straight portion 321. At this time, the pressure reducing valve 3 is locked and cannot rotate around itself under the action of the locking portion 221. It is worth noting that the function of the pressure reducing valve 3 is to stabilize the output pressure. If the pressure reducing valve 3 rotates during operation, it may affect its internal structure, such as the position of the spring or valve core, leading to unstable pressure or even leakage. Therefore, it is necessary to prevent the pressure reducing valve 3 from rotating during operation.

[0039] The bracket 2 includes a first support plate 23, a first connecting plate 24, and a second support plate 25 connected in sequence. The first connecting plate 24 is rotatably connected to the fixed frame 1. A first limiting ring 21 is connected to the first support plate 23, and a second limiting ring 22 is connected to the second support plate 25. The first support plate 23, the first connecting plate 24, and the second support plate 25 form a receiving cavity that can accommodate the pressure reducing valve 3. This effectively protects the pressure reducing valve 3 from external environmental influences such as dust and moisture, thereby extending the service life of the pressure reducing valve 3. At the same time, the enclosure of the first support plate 23, the first connecting plate 24, and the second support plate 25 enhances the stability of the entire structure, ensuring that the pressure reducing valve 3 will not shift or be damaged during operation.

[0040] Furthermore, both the first limiting ring 21 and the second limiting ring 22 are detachably connected to the bracket 2. That is, the first limiting ring 21 is detachably connected to the first support plate 23, and the second limiting ring 22 is detachably connected to the second support plate 25. Thus, the operator can replace the first limiting ring 21 and the second limiting ring 22 with different inner diameters and connect them to the bracket 2 respectively, thereby adapting to different sizes of pressure reducing valves 3 and expanding the applicability of the device.

[0041] The fixing frame 1 includes a first limiting member 13, which includes a first limiting portion 131 and a second limiting portion 132 spaced apart. The bracket 2 has a first rotation limit position and a second rotation limit position. A first connecting plate 24 is movable between the first limiting portion 131 and the second limiting portion 132. When the bracket 2 is at the first rotation limit position, the first connecting plate 24 abuts against the first limiting portion 131. When the bracket 2 is at the second rotation limit position, the first connecting plate 24 abuts against the second limiting portion 132. Specifically, the first limiting portion 131 and the second limiting portion 132 extend on the fixing frame 1 towards the side closer to the bracket 2. When the bracket 2 rotates relative to the fixing frame 1, the rotation range is located between the first limiting portion 131 and the second limiting portion 132, providing a physical barrier boundary for the rotation of the bracket 2 and preventing the bracket 2 from rotating excessively and thus being damaged. In this embodiment, when the bracket 2 is at the first rotation limit position, the first connecting plate 24 abuts against the first limiting part 131. At this time, the gas cylinder 5 is perpendicular to the ground, and the air inlet of the pressure reducing valve 3 faces the ground.

[0042] Reference Figure 3The rotary damper 4 includes a rotating shaft 41, a first connecting flange 42, and a second connecting flange 43. Both the first connecting flange 42 and the second connecting flange 43 are sleeved on the rotating shaft 41. One of the first connecting flange 42 and the second connecting flange 43 is fixedly connected to the rotating shaft 41, and the other is rotatably connected to the rotating shaft 41. The first connecting flange 42 is connected to the fixed frame 1, and the second connecting flange 43 is connected to the support 2. That is, the fixed frame 1 and the support 2 are rotatably connected through the rotating shaft 41. For example, in the rotary damper 4, the first connecting flange 42 is fixedly connected to the rotating shaft 41, and the second connecting flange 43 is rotatably connected to the rotating shaft 41. At this time, the second connecting flange 43 can rotate relative to the rotating shaft 41, thereby driving the support 2 to rotate relative to the fixed frame 1. Preferably, a damper is provided between the second connecting flange 43 and the rotating shaft 41, thereby fixing the rotation angle of the second connecting flange 43 on the rotating shaft 41, and thus fixing the rotation angle of the support 2 relative to the fixed frame 1. The same principle applies when the second connecting flange 43 in the rotary damper 4 is fixedly connected to the rotating shaft 41, and the first connecting flange 42 is rotatably connected to the rotating shaft 41.

[0043] Furthermore, the first connecting flange 42 is connected to the fixing bracket 1 by screws, and the second connecting flange 43 is also connected to the bracket 2 by screws, which improves connection efficiency and facilitates installation.

[0044] In this embodiment, the mounting bracket 1 includes a second connecting plate 11 and a first fixing plate 12 connected vertically. The second connecting plate 11 is rotatably connected to the support 2, and the first fixing plate 12 can be connected to an external structure. That is, the connection between the support 2 and the mounting bracket 1 is achieved through the rotatable connection of the first connecting plate 24 and the second connecting plate 11, reducing manufacturing costs. Furthermore, the external structure is a sparkling water machine. The first fixing plate 12 and the second connecting plate 11 are arranged perpendicularly, allowing the operator to fix the mounting bracket 1 to the sparkling water machine in a direction perpendicular to the connection surface of the first connecting plate 24 and the sparkling water machine. This is suitable for placing the gas cylinder 5 inside the sparkling water machine.

[0045] In another embodiment, refer to Figure 6 The mounting frame 1 includes a third connecting plate 14 and a second fixing plate 15 that are interconnected and arranged in parallel. The third connecting plate 14 is rotatably connected to the bracket 2, and the second fixing plate 15 can be connected to an external structure. The external structure is a sparkling water machine. The first fixing plate 12 and the second connecting plate 11 are arranged in parallel, allowing the operator to fix the mounting frame 1 to the sparkling water machine with the connecting surface of the first connecting plate 24 parallel to that of the sparkling water machine. Additionally, the mounting frame 1 in this embodiment also includes a second limiting member (not shown in the figure), the structure of which is the same as that of the first limiting member 13.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
