Description

Technical Field

[0001] This utility model relates to an adjustable fixing device for oxygen cylinders, and more particularly to an adjustable fixing device for oxygen cylinders based on an adsorption-type double-layer bracket, belonging to the field of gas cylinder protection technology. Background Technology

[0002] Oxygen cylinders are high-pressure containers used for storing and transporting oxygen. They are typically made of alloy structural steel, hot-stamped and pressed into a cylindrical shape. They are used in hospitals, emergency stations, sanatoriums, and other similar facilities. The shoulder of the cylinder is marked with a steel stamp indicating the working pressure, test pressure, volume, weight, and other information. The surface is painted sky blue, and the word "oxygen" is written in black.

[0003] Oxygen cylinders are hazardous materials. The cylinders are cylindrical and have a high center of gravity when placed vertically, making them prone to tipping over. They must be secured during use. Otherwise, the oxygen cylinder may tip over due to wind or collisions, causing damage and gas leakage. In severe cases, it may even explode, causing a safety accident. Therefore, oxygen cylinders are placed in specially designed supports during storage.

[0004] Most existing oxygen cylinder fixing brackets are assembled from multiple steel rods using simple welding methods, resulting in poor fixing effect, inability to adapt to different specifications of oxygen cylinders, and inconvenience in operation. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an adjustable fixing device for oxygen cylinders based on an adsorption-type double-layer support.

[0006] The technical solution adopted in this utility model is as follows: An adjustable fixing device for oxygen cylinders based on an adsorption-type double-layer support is designed, comprising an upper support and a lower support; the upper support includes a fixing ring, a first telescopic leg, and a suction cup, with three sets of first telescopic legs circumferentially hinged to the fixing ring, and the suction cup hinged to the lower end of each first telescopic leg; the lower support includes a fixing ring and a second telescopic leg, with three sets of second telescopic legs circumferentially hinged to the fixing ring; both the first and second telescopic legs are adjustable and lockable telescopic structures, and the first and second telescopic legs on the upper and lower supports correspond one-to-one and are hinged in pairs.

[0007] The upper and lower supports, with their fixing rings, provide stable and reliable support for the oxygen cylinder at different heights. Both the first and second telescopic legs are adjustable and lockable, allowing for easy adjustment of the overall height to accommodate varying support needs. The upper and lower supports are hinged together by the first and second telescopic legs, forming a single, integrated structure for ease of use. The tilt angle of the support legs can be flexibly adjusted by hinges between the first and second telescopic legs and their corresponding fixing rings, by hinges between the first and second telescopic legs, and by hinges between the suction cups and the first telescopic legs, adapting to different spatial requirements. The suction cups ensure a more secure connection between the first telescopic legs and the ground. Furthermore, because the first and second telescopic legs are adjustable, one set of hinged legs can be fixed to a wall using the suction cups, providing greater flexibility in support.

[0008] Furthermore, the fixing ring comprises three arc-shaped plates, one of which is hinged to the other two arc-shaped plates at both ends to form a chain-like structure. The other two arc-shaped plates are detachably connected by a locking mechanism. During installation, the fixing ring can be easily mounted onto the oxygen cylinder, making assembly and disassembly convenient.

[0009] Furthermore, the locking mechanism includes a locking rod, a locking cap, and a first and a second locking plate respectively disposed on two detachably connected arc-shaped plates. The first and second locking plates are each provided with a locking groove. Ear plates are respectively disposed on both sides of the first locking plate at the locking groove. The locking rod is hinged to the ear plates via a pin. The locking rod is threaded, and the locking cap is threadedly connected to the locking rod. The fixing ring can be opened or closed by rotating the locking rod and tightening or loosening the locking cap, making operation convenient.

[0010] Furthermore, the locking cap is a nut that passes through the locking rod. The size of the inner cavity of the fixing ring can be adjusted by adjusting the position of the locking cap on the locking rod. This structure can be used to fix and support oxygen cylinders of different specifications.

[0011] Furthermore, the fixing ring is provided with a C-shaped buckle, and the first telescopic leg and the second telescopic leg are respectively hinged to the fixing ring through the C-shaped buckle, which facilitates the connection.

[0012] Furthermore, the outer end of the C-shaped buckle of the upper support is provided with a limiting plate, which is inclined at 25° to help limit the rotation angle of the first telescopic leg.

[0013] Furthermore, the first telescopic leg includes a first sleeve and a first telescopic rod inserted into the first sleeve. A first strip-shaped hole is provided through the first sleeve. A first locking screw is provided on one opposite side of the upper end of the first telescopic rod, which is locked in the first strip-shaped hole. A first locking nut is provided on the first locking screw on both sides. The two nuts lock simultaneously on different sides, making the locking of the first sleeve and the first telescopic rod more secure.

[0014] Furthermore, the second telescopic leg includes a second sleeve and a second telescopic rod inserted into the second sleeve. A second slotted hole is provided through the second sleeve. A second locking screw, which engages with the second slotted hole, is provided on opposite sides of the upper end of the second telescopic rod. A second locking nut is provided on each of the two locking screws. The simultaneous locking of the two nuts on opposite sides ensures a more secure lock on the second sleeve and the second telescopic rod.

[0015] Furthermore, the lower ends of the first telescopic rod and the second telescopic rod are respectively provided with hinge plates, and a hinge shaft is provided between the two hinge plates, making the connection simple.

[0016] Furthermore, a connecting plate is provided between the fixing rings of the upper and lower supports. The connecting plates are arranged in an array along the circumference of the fixing rings to form a cage-like structure, which provides more reliable fixed support for the oxygen cylinder.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention features a double-layer support design to enhance the support and fixation of oxygen cylinders. The length and angle of the first and second telescopic legs are adjustable to adapt to different oxygen cylinder placement scenarios and varying support height requirements, making it more flexible and convenient to use. The suction cup design further stabilizes the fixing device after installation, strengthening the fixation effect. Additionally, the adjustable size of the inner cavity of the fixing ring allows for use with oxygen cylinders of different sizes, making operation and use even more convenient.

[0026] Example 1

[0027] like Figure 1-3 As shown, an adjustable oxygen cylinder fixing device based on an adsorption-type double-layer support includes an upper support 1 and a lower support 2. A connecting plate 27 is provided between the upper support 1 and the lower support 2. At least three connecting plates 27 are arranged in a circumferential array to form a cage-like adjustable oxygen cylinder fixing device, which has a better support and fixing effect and provides a certain degree of protection for the oxygen cylinder.

[0028] The upper support 1 includes a fixing ring 3, a first telescopic leg 4, and a suction cup 5. The fixing ring 3 is circumferentially arranged with three sets of first telescopic legs 4, and the lower end of the first telescopic leg 4 is hinged to the suction cup 5. The lower support 2 includes a fixing ring 3 and a second telescopic leg 6 (a suction cup 5 can also be provided to improve the fixing effect). The fixing ring 3 is circumferentially arranged with three sets of second telescopic legs 6. Both the first telescopic leg 4 and the second telescopic leg 6 are telescopic structures with adjustable length and lockable, such as threaded connection structures, hydraulic connection structures, and structures that are locked by screws after insertion. The first telescopic leg 4 and the second telescopic leg 6 on the upper support 1 and the lower support 2 correspond one-to-one and are hinged in pairs.

[0029] In this embodiment, the hinge structure between the first telescopic leg 4 and the second telescopic leg 6 and the fixing ring 3 is as follows: a C-shaped buckle 14 is welded onto the fixing ring 3, and the first telescopic leg 4 and the second telescopic leg 6 are respectively hinged to the fixing ring 3 through the C-shaped buckle 14. More specifically, a limiting plate 15 is welded to the outer end of the C-shaped buckle 14 of the upper bracket 1. The limiting plate 15 is inclined at no more than 25°. It can be understood that when the limiting plate is set, the suction cup of the telescopic leg can no longer be used to adhere to the wall.

[0030] Example 2

[0031] This embodiment is an optimization of the fixing ring 3 based on embodiment 1. In this embodiment, the fixing ring 3 includes three arc-shaped plates, each of which can be one-third of a circular ring. The two ends of one arc-shaped plate are respectively hinged to the other two arc-shaped plates, and the other two arc-shaped plates are detachably connected by a locking mechanism 7.

The first locking plate 10 and the second locking plate 11 are respectively provided with locking grooves 12. Ear plates 13 are respectively provided on both sides of the first locking plate 10 located in the locking grooves 12. The locking rod 8 is hinged to the ear plates 13 by a pin. The locking rod 8 is threaded, and the locking cap 9 is threadedly connected to the locking rod 8. Here, the locking cap 9 can be a regular nut or a hand-tightened Torx nut. More preferably, the locking cap 9 is a nut and is disposed on the locking rod 8. The inner size of the fixing ring 3 can be adjusted by adjusting the position of the locking cap 9 on the locking rod 8. It is understood that the locking rod 8 is relatively long.

[0033] Example 3

[0034] This embodiment further refines the structure of the first telescopic leg 4 and the second telescopic leg 6 based on embodiment 2. In this embodiment, the first telescopic leg 4 includes a first sleeve 16 and a first telescopic rod 17 inserted into the first sleeve 16. A first slotted hole 18 is provided through the first sleeve 16. A first locking screw 19, which is engaged in the first slotted hole 18, is provided on one opposite side of the upper end of the first telescopic rod 17.

Specifically, one hinge plate 26 is provided at the lower end of the first telescopic rod 17, and two hinge plates 26 are provided at the lower end of the second telescopic rod 22. The hinge plate 26 at the lower end of the first telescopic rod 17 is inserted between the two hinge plates 26 at the lower end of the second telescopic rod 22, and then the hinge shaft is passed through to achieve the hinge.

[0037] When using this application, place the oxygen cylinder in the designated location, then hold this application tightly to the oxygen cylinder, adjust the length and angle of the first telescopic leg 4 and the second telescopic leg 6, then attach the suction cup 5 to the ground, and finally lock the length of the first telescopic leg 4 and the second telescopic leg 6.
