DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0026] Specifically, Figure 1 As shown, an embodiment of the present application provides an acetylene cylinder conveying device, which fixes an acetylene cylinder 120 by providing a fixing frame 100, wherein four fixing positions 110 are provided on the fixing frame 100, and the four fixing positions 110 are arranged in a rectangular shape on the fixing frame 100, and the fixing positions 110 are used to fix the acetylene cylinder 120. In the embodiment of the present application, four acetylene cylinders 120 are provided, and the four acetylene cylinders 120 are installed corresponding to the positions of their fixing positions 110, so that the acetylene cylinders 120 are arranged in a rectangular shape, which is convenient for the use of the acetylene cylinders 120.

[0027] In this application, with respect to the transportation of the acetylene gas, multiple embodiments are provided to achieve the technical effects of this application.

[0028] Embodiment 1:

[0029] like Figure 1 As shown, a transport pipe 200 is provided at one side of the fixing frame 100. The transport pipe 200 is a steel pipe, which can conveniently transport acetylene gas. Specifically, a transport cavity 210 is formed in the steel pipe, and an output port 230 is provided at one end of the transport pipe 200. The output port 230 is connected to the transport cavity 210. The transport cavity 210 can transport acetylene gas. One end of the steel pipe is connected to an external device to facilitate the external device to use its acetylene gas.

[0030] Among them, four docking ports 220 are arranged on the transport pipe 200, and the four docking ports 220 are evenly arranged on the transport pipe 200, and the four docking ports 220 are all connected to its transport cavity 210, wherein the four docking ports 220 are correspondingly connected to a connecting pipe 300, and the connecting pipe 300 is arranged in four, each corresponding one to the docking port 220.

[0031] The other end of the connecting pipe 300 is respectively connected to the openings of four acetylene bottles 120, so that the acetylene gas in the four acetylene bottles 120 enters the transport chamber 210 through the connecting pipe 300, which facilitates the overall transportation of the acetylene gas. The connecting pipe 300 is provided with an air pressure valve, and the opening and closing of the acetylene bottles 120 can be controlled by the air pressure valve. Specifically, when less acetylene gas is needed, the air pressure valve on one of the connecting pipes 300 can be opened to transport the acetylene in one of the acetylene bottles 120. At this time, the other three acetylene bottles 120 are closed by the air pressure valve, and the flow rate of the acetylene gas can be controlled to avoid unnecessary waste. When more acetylene gas is needed, the air pressure valves corresponding to two, three or four of the acetylene bottles 120 can be opened to facilitate the transportation of a large amount of acetylene gas.

[0032] Embodiment 2:

[0033] like Figure 2 As shown, a transport pipe 200 is provided at both sides of the fixing frame 100, and the two transport pipes 200 are symmetrically arranged on the fixing frame 100. The two transport pipes 200 are both steel pipes, wherein a transport cavity 210 is provided on the two transport pipes 200, and an output port 230 is provided at one end of the transport pipe 200, and the output port 230 is connected to the transport cavity 210. The two transport cavities 210 can transport acetylene gas, and one end of the steel pipe is connected to an external device to facilitate the external device to use its acetylene gas.

[0034] Among them, two docking ports 220 are provided on each of the two transport pipes 200, and the two docking ports 220 are correspondingly connected with connecting pipes 300, so that the acetylene gas in the acetylene cylinder 120 enters the transport cavity 210 through the connecting pipe 300. In the second embodiment of the present application, the transport pipes 200 correspond to two of the acetylene cylinders 120, so that the acetylene gas in one acetylene cylinder 120 can be transported or the acetylene gas in two acetylene cylinders 120 can be transported, thereby avoiding the acetylene gas in the four acetylene cylinders 120 being transported through one transport pipe 200, resulting in an increase in the gas pressure in the transport cavity 210 and affecting the transport pipe 200.

[0035] In the above, a gas pressure valve is also provided on the connecting pipe 300 , and the acetylene gas is transported in the connecting pipe 300 and the transport chamber 210 under the control of the gas pressure valve.

[0036] Embodiment three:

[0037] like Figure 3 As shown, in the third embodiment of the present application, the internal structure of the transport tube 200 is mainly improved, and the content of the improvement can be selected based on the structure in the first and second embodiments of the present application.

[0038] In the third embodiment of the present application, a one-way valve structure 400 is arranged in the transport chamber 210. The one-way valve structure 400 includes a fixing part 410. The fixing part 410 can be snapped into the transport chamber 210 to separate the transport chamber 210 so that the transport chamber 210 is divided into a first chamber 240 and a second chamber 250 through the fixing part 410.

[0039] In the above, the description of the first chamber 240 and the second chamber 250 is only limited to the convenience of structural description in this application, and there is no textual description of the chamber in a physical sense. Acetylene gas can flow from the first chamber 240 to the second chamber 250 through its fixing member 410, and the flow flows through the through hole 411 opened on the fixing member 410, and the through hole 411 connects the first chamber 240 and the second chamber 250. In the third embodiment of the present application, a hollow support member 420 is provided in the first chamber 240, and the hollow support member 420 is fixedly connected to the fixing member 410, which is convenient for the fixing member 410 to be connected to the hollow support member 4 20 moves together and is installed and disassembled in its transport chamber 210. A light spring 430 is fixedly connected to the hollow support member 420. One end of the light spring 430 is located in the first chamber 240 and is connected to the hollow support member 420. The other end enters into the second chamber 250 through its through hole 411. A light ball 440 is fixedly connected to a section of the light spring 430 located in the second chamber 250. The light ball 440 abuts against one end of its through hole 411 toward the second chamber 250 through the pulling force of its light spring 430, so that the light ball 440 blocks its through hole 411, thereby separating the first chamber 240 and the second chamber 250.

[0040] On the basis of the above structure, the one-way flow of acetylene gas can be achieved. Specifically, a docking port 220 is opened in the first chamber 240, and the docking port 220 can be connected to one of the acetylene bottles 120 through its connecting pipe 300. When the acetylene releases the pressure, the acetylene gas enters the first chamber 240 through its docking port 220. Due to the high pressure of the gas, the acetylene gas pushes the lightweight ball 440 through the hollow support member 420 and the through hole 411, so that the lightweight ball 440 moves in the direction away from the first chamber 240, which facilitates the transportation of acetylene gas. When the acetylene bottle 120 is closed, the gas pressure is reduced, and the lightweight ball 440 is pressed against the through hole 411 under the elastic force of its lightweight spring 430, thereby separating the first chamber 240 and the second chamber 250.

[0041] In the above, the one-way valve structure 400 can prevent the backflow of acetylene gas and avoid the waste of gas residue after the use of acetylene gas.

[0042] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
