Description

Technical Field

[0001] This utility model relates to the technical field of gas cylinders, and in particular to an anti-tipping structure for gas cylinders. Background Technology

[0002] Gas cylinders are indispensable core equipment for gas storage and transportation in chemical production, pharmaceutical research and development, scientific research experiments, and industrial manufacturing. They are widely used to load various gases, including mixed gases, specialty gases, and reaction raw material gases. Their design must balance sealing, pressure resistance, and safety, and they are usually made of high-strength metal materials to meet the gas storage needs of different pressure levels.

[0003] When gas cylinders are stored centrally, a standardized frame, fence, or array-style fixing structure is typically used to prevent the cylinders from tipping over. However, this structural design lacks specific adaptability, and it does not provide portable, independent anti-tipping capabilities for individual cylinders in independent operating scenarios (such as individual sampling in the laboratory or temporary use on-site). These centralized protective structures cannot be disassembled or individually adapted to individual cylinders, making it difficult to meet the anti-tipping and stable fixing requirements of individual cylinders in independent operating scenarios.

[0004] Currently, no effective solution has been proposed to address the problem that centralized anti-tipping structures in related technologies are difficult to adapt to the independent operation of individual gas cylinders. Utility Model Content

[0116] The dimensions of the clamping element 61 are matched with the dimensions of the main body element 11. Generally, the length and width of the clamping element 61 are smaller than the radial dimension (inner diameter) of the inner edge surface of the main body element 11, and the height of the clamping element 61 is greater than the axial dimension of the main body element 11.

[0117] In some of these embodiments, the clamping element 61 is made of metal.

[0118] In some of these embodiments, the clamping element 61 is a clamping plate.

[0119] In some embodiments, the third control element 62 includes a second threaded rod and a turntable. The second threaded rod is rotatably disposed on the other side of the clamping element 61 and threadedly connected to the corresponding second connecting element 15; the turntable is disposed at the end of the second threaded rod and connected to the second threaded rod, for driving the second threaded rod to rotate circumferentially along the corresponding second connecting element 15.

[0120] The dimensions of the second threaded rod are matched with the dimensions of the clamping element 61. Generally, the radial dimension of the second threaded rod is smaller than the length and height of the clamping element 61, and the axial dimension of the second threaded rod is larger than the width of the clamping element 61.

[0121] The dimensions of the second threaded rod are matched with the dimensions of the second connecting element 15. Generally, the radial dimension of the second threaded rod is equal to the radial dimension of the second connecting element 15, and the axial dimension of the second threaded rod is greater than the axial dimension of the second connecting element 15.

[0122] In some embodiments, the third control element 62 and the clamping element 61 are rotatably connected without separation. For example, the third control element 62 and the clamping element 61 are connected via a bearing housing.

[0123] In some of these embodiments, the third control element 62 is threadedly connected to the second connecting element 15.

[0124] In some of these embodiments, the third control element 62 is made of metal.

[0125] The method of using this utility model is as follows: (a) Support operations A support element 21 is rotated by a second rotating element 23 along the circumferential direction of the corresponding first rotating element 16 toward the corresponding limiting element 31 until the support element 21 abuts against the corresponding limiting element 31, thereby unfolding. The remaining support elements 21 are unfolded using the above operations, and each unfolded support element 21 is placed on the ground (see reference). Figure 1 As shown in the figure, that is, placed in the designated location; Insert the hex wrench into the second control element 52 and twist the hex wrench so that it drives the first control element 51 to rotate circumferentially along the first connecting element 14 and move downward along the axis of the first connecting element 14. The first control element 51 drives the movable element 41 to move along the axial direction of the cavity element 13. The movable element 41 drives each second snap-fit ​​element 42 to move accordingly until each second snap-fit ​​element 42 snaps into the corresponding first snap-fit ​​element 22, thereby fixing the unfolded support element 21.

[0126] (ii) Placement of gas cylinder A Place gas cylinder A at the inner middle position of the main component 11; Twist a third control element 62 to rotate it circumferentially along the corresponding second connecting element 15 and move it axially toward the gas cylinder A until it comes into contact with the gas cylinder A. Twist another third control element 62 to make it rotate circumferentially along the corresponding second connecting element 15 and move it axially toward the gas cylinder A until it comes into contact with the gas cylinder A.

[0127] The advantages of this invention are as follows: The cooperation between the main body unit and the support unit provides a stable support foundation for the anti-tipping structure. The main body unit provides a rotation mounting point for the support unit, allowing the support unit to unfold and form multi-directional support, improving the structure's load-bearing stability on the gas cylinder and avoiding the problem of easy tipping from a single support point. The limiting unit controls the support angle, restricting the maximum unfolding angle of the support unit to prevent excessive rotation and structural imbalance, while ensuring consistent unfolding angles for all support units and uniform force distribution. The cooperation between the stabilizing unit and the control unit secures the support unit, locking its unfolded state through vertical movement and locking, thus improving support stability. The clamping unit adapts and secures the gas cylinder, adjusting the clamping distance through horizontal opposing or back-to-back movements to accommodate gas cylinders of different diameters.

[0128] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by 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.
