Description

Technical Field

[0001] The utility model relates to the technical field of gas storage, in particular to a portable gas bottle. Background Art

[0002] Gas cylinders are very common in our daily life. They are used to store liquefied petroleum gas, butane gas, natural gas and other gases. Gas cylinders can provide fuel for the combustion of flames. With the development of society, portable gas cylinders have gradually come into the public eye because of their light weight and convenience to carry, and are loved by many people.

[0003] For example, a Chinese utility model patent (CN204005236U) discloses a portable butane gas cylinder, which records: "The top cover of the gas cylinder adopts a special curved surface design, and the bottom cover of the gas cylinder adopts a spherical design, which effectively improves the pressure-bearing capacity of the gas cylinder and reduces the material thickness. The gas cylinder tank body is made of high-quality tinplate sheets welded by high-frequency resistance welding. The weld strength exceeds the strength of the material itself, which can effectively ensure the safety of the gas cylinder. At the same time, the gas cylinder valve is designed as a right-angle elbow valve to ensure that the butane gas output by the valve is completely in a gas phase state to meet the combustion requirements of the stove." It also records: "The defects of traditional liquefied petroleum gas cylinders: First, the cylinder is large and bulky, which does not meet the needs of convenience. Secondly, it needs to be connected to the stove with a hose, which is inconvenient to move and prone to aging and leakage. Thirdly, the use of propane-butane mixed gas has a high gas pressure (0.5-0.7MPa) and is not safe." Technical problems.

[0004] In summary, it can be seen that the following technical problems exist in the prior art: although the gas cylinder in the above patent is made of high-quality tinplate sheet material welded by high-frequency resistance welding, and the weld strength exceeds the strength of the material itself, the strength of the unwelded position has not changed.

In addition, the bottle body is slender and not only easy to tip over when placed on the ground, but also difficult to carry. For this reason, the present application proposes a portable gas cylinder to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] Please refer to Figure 1-Figure 3 A portable gas cylinder comprises: a base 1, a gas cylinder liner 2, a protective mechanism 3, a supporting mechanism 4 and a gas cylinder valve 5, wherein the base 1 is movably connected to the gas cylinder liner 2, the top of the gas cylinder liner 2 is fixedly connected to the gas cylinder valve 5, the outer side of the gas cylinder liner 2 is provided with a protective mechanism 3 for protecting the gas cylinder liner 2, and the outer side of the base 1 is provided with a supporting mechanism 4 for facilitating the placement and movement of the device;

[0036] Specifically, the protection mechanism 3 includes a protective shell 6, a connecting buckle 7 and a top cover assembly. Two protective shells 6 are arranged on the outer side of the gas cylinder inner liner 2. The lower ends of the two protective shells 6 are rotatably connected to the base 1 through hinges. The outer sides of the two protective shells 6 are fixedly connected with connecting buckles 7, and the two protective shells 6 are buckled and connected by the connecting buckles 7.

[0037] Furthermore, the top cover assembly includes a protective cover 9, an external thread 10, a flip cover 11 and a magnetic buckle 12. The protective cover 9 is arranged above the protective shell 6. The external thread 10 is provided on the surface of the protective shell 6 and at a position corresponding to the protective cover 9. The protective cover 9 is threadedly connected to the protective shell 6 through the external thread 10. A cover opening 13 is provided in the middle of the protective cover 9 and at a position corresponding to the gas cylinder valve 5. The flip cover 11 is rotatably connected to the top of the protective cover 9 and at a position corresponding to the cover opening 13, and the outer side of the flip cover 11 is fixedly connected to the magnetic buckle 12.

[0038] Furthermore, a plurality of polyurethane foams 8 are fixedly connected to the inner side of the protective shell 6 , and the polyurethane foams 8 are tightly fitted to the surface of the gas cylinder liner 2 .

[0039] It can be seen that when in use, the flip cover 11 can be directly opened, and the gas inside the gas cylinder liner 2 can be used from the cover opening 13 and the gas cylinder valve 5, which is convenient and quick, and during transportation and use, the base 1, the protective shell 6 and the protective cover 9 will provide all-round protection for the gas cylinder liner 2, thereby preventing the gas cylinder liner 2 from being damaged due to accidents, and there are polyurethane foam 8 and air between the protective shell 6 and the gas cylinder liner 2, both of which are good heat insulation media, which can effectively reduce heat conduction and effectively prevent the gas inside the gas cylinder liner 2 from being affected by temperature; when the gas cylinder liner 2 needs to be replaced, the protective cover 9 can be rotated and removed, and the two protective shells 6 can be turned outward by opening the connecting buckle 7, so that the gas cylinder liner 2 can be directly taken out from the inside of the base 1, so that the device can be reused, which effectively improves the stability and safety of the device.

[0040] Embodiment 2:

[0041] The portable gas cylinder provided in Example 1 is further optimized, specifically, as follows Figure 4-Figure 5 As shown, further, the support mechanism 4 includes a fixing groove 14, a support plate 15, an adjustment component and a moving component. The outer side of the base 1 is fixedly connected with the fixing groove 14, and the lower end of the fixing groove 14 is rotatably connected with the support plate 15.

[0042] Furthermore, the adjustment assembly includes a sliding block 16, a connecting rod 17, a threaded rod 18 and a knob 19. The threaded rod 18 is rotatably connected inside the fixed groove 14, and the sliding block 16 is threadedly connected to the outer side of the threaded rod 18. The sliding block 16 is slidably connected to the fixed groove 14, and the connecting rod 17 is rotatably connected to the outer side of the sliding block 16. The end of the connecting rod 17 away from the sliding block 16 is rotatably connected to the middle of the support plate 15, and the knob 19 is rotatably connected to the upper end of the fixed groove 14 and at a position corresponding to the threaded rod 18, and the knob 19 is fixedly connected to the threaded rod 18.

[0043] It can be seen that when in use, the knob 19 can be rotated to drive the threaded rod 18 to rotate, thereby driving the sliding block 16 threadedly connected to the threaded rod 18 to move, and the movement of the sliding block 16 drives the connecting rod 17 to make the support plate 15 flip outward and open, thereby supporting both sides of the device to prevent the device from tipping over when placed.

[0044] Furthermore, the moving component includes a roller 20, an insert block 21, a slot 22, a positioning hole 23 and a hand-tightening bolt 24. A slot 22 is provided at one end of the support plate 15 away from the fixing slot 14. The inside of the slot 22 is plugged and connected with the insert block 21. The outer side of the insert block 21 is rotatably connected with the roller 20. The outer side of the support plate 15 is threadedly connected with the hand-tightening bolt 24. A positioning hole 23 is provided on the surface of the insert block 21 and at a position corresponding to the hand-tightening bolt 24. The hand-tightening bolt 24 extends to the inside of the positioning hole 23.

[0045] It can be seen that when the device needs to be moved, the plug block 21 can be inserted into the slot 22, and then the hand-tightening bolt 24 can be rotated to enter the positioning hole 23 to quickly connect the roller 20 with the support plate 15, so that the device can be quickly moved on the ground. When the device reaches the specified position, it is only necessary to rotate the hand-tightening bolt 24 again to disengage the hand-tightening bolt 24 from the positioning hole 23, and then the roller 20 and the plug block 21 can be pulled out of the slot 22 as a whole to prevent the device from moving.
