Description

Technical Field

[0001] The utility model relates to the field of gas storage tanks, in particular to a portable liquid oxygen storage tank. Background Art

[0002] Liquid oxygen storage tanks are tanks that liquefy oxygen under high pressure. This type of tank has strict requirements when storing oxygen, because improper operation of liquid oxygen storage tanks during use and transportation, equipment damage, sparks and static electricity can all lead to explosions. Therefore, there are some hidden dangers when carrying portable liquid oxygen storage tanks currently used. At present, liquid oxygen storage tanks need to be moved with special carts, which on the one hand increases the purchase cost, and on the other hand, this type of cart is prone to friction with the liquid oxygen storage tank body during movement, thereby causing static electricity. In addition, this type of cart has poor buffering performance, and bumps may even generate sparks and collision hazards. In addition, when in use, the angle position of the traditional liquid oxygen storage tank protection and control handle cannot be adjusted. On the one hand, it is not convenient to adjust to the appropriate position for movement, and on the other hand, it is easy to block the connection end, which is not convenient for wiring the pipe. Therefore, its use is not flexible enough. For this reason, we propose a portable liquid oxygen storage tank. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] Embodiment 1:

[0019] like Figure 1-4 As shown, a portable liquid oxygen storage tank comprises a storage tank body 1, a rear support seat 2 is fixedly installed on the lower surface of the storage tank body 1, a buffer movable structure 3 is fixedly installed on the surface of the storage tank body 1 near the lower surface, a control valve 4 is fixedly installed on the upper end of the storage tank body 1, and an adjustable movable structure 5 is sleeved and installed on the upper end of the storage tank body 1 around the control valve 4;

[0020] The buffer moving structure 3 includes a limit installation tube 301, a telescopic tube 302, a limit ring 303, a buffer spring 304, a moving cross bar 305 and a moving wheel 306. The telescopic tube 302 is movably installed inside the limit installation tube 301, and the limit ring 303 is fixedly installed on the surface of the telescopic tube 302. The surface of the telescopic tube 302 is located above the limit ring 303 and is sleeved with a buffer spring 304. The lower end of the telescopic tube 302 is fixedly installed with a moving cross bar 305, and both ends of the moving cross bar 305 are movably installed with moving wheels 306 through bearings; the limit installation tube 301, the telescopic tube 302, the limit ring 303 and the buffer spring 304 are provided with two groups in total, and the surfaces of the two limit installation tubes 301 are fixedly installed with connecting blocks, and the limit installation tubes 301 are fixed to the surface of the storage tank body 1 through the connecting blocks. The lower ends of the tubes 302 are fixedly mounted on the surface of the same movable cross bar 305. When encountering bumpy roads during transportation, the telescopic tubes 302 will transmit the amplitude of the bumps to the buffer springs 304. The buffer springs 304 reduce the bumps by buffering, making transportation smoother and more convenient to carry and use. The surface of the control valve 4 is fixedly connected with a connecting end 401. The adjustable movable structure 5 includes a rotating ring groove 501, a rotating slip ring 502 and a protection and control handle 503. The rotating ring groove 501 is slidably mounted with a rotating slip ring 502. The upper surface of the rotating slip ring 502 is fixedly mounted with a protection and control handle 503 near the edge. The rotating slip ring 502 is movably sleeved in the rotating ring groove 501. When the rotating slip ring 502 rotates, it can drive the protection and control handle 503 to rotate. This makes production, movement and connection more convenient.

[0021] It should be noted that the utility model is a portable liquid oxygen storage tank. When moving, the user can rotate the protection and control handle 503 on the rotating ring groove 501 to a suitable position through the rotating slip ring 502, and then tilt the storage tank body 1 so that the two moving wheels 306 contact the ground, and then pull the protection and control handle 503 to move the storage tank body 1. When encountering an uneven road surface during movement, the buffer spring 304 can reduce the degree of bumping through its buffering performance, thereby making the storage tank body 1 smoother during transportation, avoiding collisions during transportation, and making it safer to carry. In addition, the adjustable movable structure 5 can adjust the protection and control handle 503 to any angle, which not only does not affect the adjustment of the moving angle, but also does not affect the interface that blocks the connection end 401, and when installing the control valve 4, there is no need to consider that the final direction of the connection end 401 is not blocked.

[0022] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
