Technical Field
[0001] This utility model relates to the field of gas application technology, specifically to a liquid nitrogen cylinder with a hanging bracket. Background Technology
[0002] Nitrogen, as an inert gas, is chemically stable and is often used as a protective or filling gas. For example, in welding and cutting processes, nitrogen helps prevent oxidation, and filling the packaging of fragile foods like potato chips with nitrogen prevents the food from being crushed, thus providing protection. Because of its widespread use, nitrogen needs to be stored and transported in liquid nitrogen cylinders.
[0003] Currently, there are tall, slender cylindrical liquid nitrogen cylinders on the market. These cylinders occupy little ground space and can be placed in corners or other suitable locations. Furthermore, their smooth, clean outer walls, without any protrusions, allow them to lie horizontally, facilitating stacking during transport and placement on filling equipment. While these liquid nitrogen cylinders offer many advantages, their tall, slender shape results in a small contact area with the ground, and their high center of gravity makes them prone to tipping over due to accidental collisions or pipe pulling when connected to the gas connection at the top. Additionally, the high-pressure environment containing liquid nitrogen makes the gas connection susceptible to loosening if the cylinder tipps over, posing safety hazards such as gas leakage and connection detachment. Therefore, the industry needs a structure that ensures the liquid nitrogen cylinder is not easily tipped over when placed vertically, thereby improving its stability and enhancing gas usage safety. Summary of the Invention
[0004] To address the aforementioned problems in the existing technology, the present invention aims to provide a liquid nitrogen cylinder with a hanging rack. The hanging rack has a retractable rope, allowing the cylinder to maintain stability when placed vertically. This is achieved by pulling out the rope and attaching it to a stable base such as a hook on a wall, thus restricting the upper part of the cylinder and effectively preventing safety hazards caused by accidental tipping. This results in greater stability during use and improved gas safety.
[0005] The specific technical solution is as follows: A liquid nitrogen cylinder with a hanger includes a cylinder body with a mounting through hole at the center of the top surface of the cylinder body. A gas connection is installed on the mounting through hole. The cylinder body also includes a hanger mounted on the top surface of the cylinder body. The hanger includes a slide rail, a slider, a telescopic reset component, and a rope. The slide rail is arranged circumferentially around the cylinder body. A telescopic opening is provided on one side of the slide rail. The slider is slidably disposed within the slide rail. One end of the slider is connected to a rope, and the other end of the slider is connected to the telescopic reset component. The end of the rope facing away from the slider extends to the telescopic opening. Simultaneously, the end of the telescopic reset component facing away from the slider is fixed within the slide rail.
[0006] The aforementioned liquid nitrogen cylinder with a hanging bracket is wherein the hanging bracket is fitted outside the gas supply connector, and the highest point of the hanging bracket is lower than the lowest point of the control valve and interface of the gas supply connector.
[0007] The aforementioned liquid nitrogen cylinder with a hanger includes an outer ring and a cover plate. The bottom of the outer ring is welded to the top surface of the cylinder body, and the cover plate is installed on the top surface of the outer ring. An extension port is provided on the outer ring and penetrates the inner and outer walls of the outer ring. The space between the outer ring, the top surface of the cylinder body, and the cover plate forms a slide.
[0008] In the aforementioned liquid nitrogen cylinder with a hanger, a reinforcing block is provided on the cover plate at the telescopic opening corresponding to the outer ring, and the reinforcing block is connected to the top surface of the cylinder by screws.
[0009] In the aforementioned liquid nitrogen cylinder with a hanging rack, a fixed post is provided in the slide and on the side symmetrical to the telescopic opening. The fixed post is welded to the top surface of the cylinder. The fixed post and the telescopic opening divide the slide into two symmetrical grooves. A slider is slidably installed in each groove. At the same time, the two ends of a rope are connected to the two sliders respectively. The middle part of the rope is located at the telescopic opening. Furthermore, a telescopic reset component is provided between each slider and the fixed post.
[0010] The aforementioned liquid nitrogen cylinder with a hanger further includes a limiting post, which is disposed within a slide rail and one end of which is welded to the top surface of the cylinder body. The limiting post is positioned between a fixed post and a telescopic opening. A slider and a telescopic reset component are located between the limiting post and the fixed post. A gap is provided between the limiting post and the inner wall of the slide rail. A rope connected to the slider passes through the gap and extends to the telescopic opening.
[0011] In the aforementioned liquid nitrogen cylinder with a hanger, the fixed post and the limiting post are each provided with a connection hole on the end facing away from the top surface of the cylinder body, and the cover plate is provided with mounting holes corresponding to the connection holes. Screws connect the connection holes and the corresponding mounting holes.
[0012] In the aforementioned liquid nitrogen cylinder with a hanging rack, a top-out block is also provided inside the slide and located at the telescopic opening. The top-out block is welded to the top surface of the cylinder body, and the rope is located outside the top-out block at the telescopic opening.
[0013] In the aforementioned liquid nitrogen cylinder with a hanger, there are two ejector blocks arranged at an interval.
[0014] The positive effects of the above technical solution are: The aforementioned liquid nitrogen cylinder with a hanging rack features a slide rail on its top surface, within which a slider slides. A telescopic opening is located on one side of the slide rail. One end of a rope is connected to the slider, and the other end extends to the telescopic opening. Simultaneously, a telescopic reset device installed within the slide rail is connected to the end of the slider opposite to the rope. This allows the operator to pull the rope from the telescopic opening and hang the cylinder on a hook on a stable external base when the hanging rack is needed. This restrains the upper part of the liquid nitrogen cylinder, preventing it from tipping over when placed vertically, thus improving stability and safety during use. After use, the telescopic reset device retracts the slider and rope into the telescopic opening, concealing the rope and maintaining the original state of the outer wall of the liquid nitrogen cylinder, preserving its original function.

[0017] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 4 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.
[0018] Figure 1 This is a structural diagram of an embodiment of the present invention: a liquid nitrogen cylinder with a hanging rack. Figure 2 This is a cross-sectional view of the hanging rack after the ropes have been retracted, according to a preferred embodiment of the present invention. Figure 3 This is a cross-sectional view of the hanging bracket after the rope has been pulled out, according to a preferred embodiment of the present invention. Figure 1 , Figure 2 as well as Figure 3As shown, the liquid nitrogen cylinder with a hanger provided in this embodiment includes a cylinder body 1 and a hanger 3. A mounting through-hole is provided at the center of the top surface of the cylinder body 1, allowing for the filling and discharging of liquid nitrogen and its storage within the cylinder body 1. Additionally, a gas connection 2 is installed on the mounting through-hole. This gas connection 2 includes a control valve and instruments, enabling the connection of a gas pipeline to the interface of the gas connection 2 during gas usage. The control valve regulates the flow rate and the pressure, while instruments monitor changes in parameters, ensuring controllable operation and improving gas usage safety.
[0019] Specifically, the hanger 3 is positioned on the top surface of the bottle body 1, preventing protrusions on the outer wall of the bottle body 1 and maintaining the original smoothness and cleanliness of the liquid nitrogen cylinder's outer wall, thus not affecting the performance of the liquid nitrogen cylinder itself. The hanger 3 includes a slide 31, a slider 32, a telescopic reset component 33, and a rope 34. The slide 31 is arranged circumferentially around the bottle body 1, allowing it to be positioned around the top surface of the bottle body 1, making full use of the top surface space. Simultaneously, a telescopic opening 3111 is provided on one side of the slide 31, providing conditions for the subsequent retrieval and extension of the rope 34. Furthermore, the slider 32 is slidably positioned within the slide 31, with one end of the slider 32 connected to the rope 34 and the other end connected to the telescopic reset component 33, allowing the slider 32 to slide within the slide 31, providing conditions for subsequent telescopic pull-out. Furthermore, the end of the rope 34 facing away from the slider 32 extends to the telescopic opening 3111. Simultaneously, the end of the telescopic reset member 33 facing away from the slider 32 is fixed within the slide rail 31. This allows the operator to pull the rope 34 at the telescopic opening 3111 when the rope 34 is needed to maintain the stability of the liquid nitrogen cylinder. This allows the rope 34 to be easily attached to hooks or other structures on an external stabilizing base, thus restricting the upper part of the liquid nitrogen cylinder and preventing accidental tipping during use, thereby improving gas safety. Additionally, when the rope 34 is pulled out, it pulls the slider 32 to move within the slide rail 31 and extends the telescopic reset member 33. After the rope 34 is released, the telescopic reset member 33 retracts in the opposite direction, and the slider 32 pulls the rope 34 back from the telescopic opening 3111 into the slide rail 31, fulfilling the rope 34 storage requirement without affecting the original function of the liquid nitrogen cylinder. Preferably, the telescopic reset component 33 is a tension spring, which can automatically reset after being stretched, and can be purchased and installed directly, reducing costs.
[0020] More specifically, the bracket 3 is mounted outside the gas connector 2, and the highest point of the bracket 3 is lower than the lowest point of the control valve and interface of the gas connector 2. This makes it convenient for the operator to operate the control valve when using gas, and also makes it easy for the operator to install and remove the gas pipeline at the interface. This avoids the problem of the bracket 3 blocking the gas connector 2 and affecting its use.
[0021] More specifically, the hanger 3 includes an outer ring 311 and a cover plate 312. The bottom of the outer ring 311 is welded to the top surface of the bottle body 1, achieving a fixed connection between the outer ring 311 and the bottle body 1. Since the top surface of the bottle body 1 is a protruding arc-shaped surface, there is a height difference between the outer ring 311 and the top surface of the bottle body 1. Simultaneously, the cover plate 312 is installed on the top surface of the outer ring 311, and the telescopic opening 3111 is set on the outer ring 311, penetrating both the inner and outer walls of the outer ring 311. This creates a slide 31 between the outer ring 311, the top surface of the bottle body 1, and the cover plate 312. This prevents the slider 32 from easily detaching from the slide 31 when it is subsequently placed within it, resulting in a more rational structural design. Furthermore, the hanger 3 allows for disassembly and reassembly. By disassembling and assembling the cover plate 312, the slider 32, the telescopic reset component 33, and the rope 34 can be installed, further enhancing the structural design.
[0022] Figure 4 for Figure 1 An enlarged view of section A. (See image below.) Figure 1 and Figure 4 As shown, a reinforcing block 3112 is also provided on the cover plate 312 at the telescopic opening 3111 corresponding to the outer ring 311. The reinforcing block 3112 is connected to the top surface of the bottle body 1 by screws. That is, the reinforcing block 3112 strengthens the structure at the telescopic opening 3111 for pulling the rope, so that the rope 34 will not be damaged when it is pulled or when the liquid nitrogen cylinder is pulled by the rope 34. The structural design is more reasonable.
[0023] More specifically, a fixing post 4 is also provided within the slide 31 and on the side symmetrical to the telescopic opening 3111. The fixing post 4 is welded to the top surface of the bottle body 1. The fixing post 4 and the telescopic opening 3111 divide the slide 31 into two symmetrical grooves. A slider 32 is slidably installed in each groove. Simultaneously, both ends of a rope 34 are connected to the two sliders 32, and the middle of the rope 34 is positioned at the telescopic opening 3111. Furthermore, a telescopic reset member 33 is provided between each slider 32 and the fixing post 4. This allows the two sliders 32 to move synchronously when the rope 34 is pulled at the telescopic opening 3111, simultaneously stretching the telescopic reset member 33. This doubles the pulling speed of the rope 34, making the structure more sensitive. At the same time, it halves the stretching stroke of each telescopic reset member 33, reducing the length and deformation of the telescopic reset member 33 itself, resulting in higher structural reliability and a longer service life.
[0024] More specifically, a limiting post 5 is also provided inside the slide 31, and one end of the limiting post 5 is welded to the top surface of the bottle body 1, realizing the stable arrangement of the limiting post 5 inside the slide 31, providing conditions for reliably limiting the movement stroke of the slider 32. In addition, the limiting post 5 is set between the fixed post 4 and the telescopic opening 3111, and the slider 32 and the telescopic reset member 33 are located between the limiting post 5 and the fixed post 4, so that the movement stroke range of the slider 32 is within the range between the fixed post 4 and the limiting post 5, preventing the slider 32 from falling out of the corresponding groove and causing the hanger 3 to fail. In addition, a gap is provided between the limiting post 5 and the inner wall of the slide 31, so that the rope 34 connected to the slider 32 can pass through the gap and extend to the telescopic opening 3111, meeting the pull-out requirements of the rope 34, making the structural design more reasonable.
[0025] More specifically, connecting holes are provided on the ends of the fixed post 4 and the limiting post 5 that are away from the top surface of the bottle body 1. The cover plate 312 is provided with mounting holes that correspond one-to-one with the connecting holes. This allows the connecting holes and the corresponding mounting holes to be connected by screws when the cover plate 312 is installed on the top surface of the outer ring 311, thus realizing the installation of the cover plate 312. This also makes full use of the structure of the fixed post 4 and the limiting post 5, making the structure more rationally utilized.
[0026] More specifically, an ejector block 6 is provided inside the slide 31 and at the telescopic opening 3111. The ejector block 6 is welded to the top surface of the bottle body 1, thus achieving a fixed installation of the ejector block 6 at the telescopic opening 3111. In addition, the rope 34 is located outside the ejector block 6 at the telescopic opening 3111. That is, the ejector block 6 prevents the rope 34 from being completely retracted into the telescopic opening 3111, making it easier for the operator to grab the rope 34 from the telescopic opening 3111 and pull it out, making it more convenient to use.
[0027] In a preferred embodiment, two ejector blocks 6 are provided, and the two ejector blocks 6 are arranged at intervals, so that there is a gap between the two ejector blocks 6, which makes it convenient for the operator's fingers to reach into the gap between the two ejector blocks 6 to pinch the rope 34, and further facilitates the pulling out of the rope 34.
[0028] The liquid nitrogen cylinder with a hanger 3 provided in this embodiment includes a cylinder body 1 and a hanger 3. A slide 31 is provided on the top surface of the cylinder body 1, and a slider 32 is slidably arranged in the slide 31. At the same time, a telescopic port 3111 is provided on one side of the slide 31, and one end of a rope 34 is connected to the slider 32, while the other end extends to the telescopic port 3111. The end of the slider 32 facing away from the rope 34 is connected to a telescopic reset member 33. This allows the rope 34 to be pulled out through the telescopic port 3111 and hung on a hook on an external stable base when it is necessary to restrict the upper part of the liquid nitrogen cylinder. This prevents the liquid nitrogen cylinder from tipping over during use and improves gas safety. In addition, after use, the slider 32 can be pulled back into the slide 31 by the telescopic reset member 33 to hide the rope 34 without affecting the outer wall of the liquid nitrogen cylinder, thus ensuring the original function of the liquid nitrogen cylinder.
[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
