DETAILED DESCRIPTION OF THE INVENTION

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Referring to Figures 1 - 4 , an embodiment provided by the present utility model: a vehicle liquefied gas cylinder with leak prevention, including a bottle top 1, handles 3 are symmetrically arranged at the top end of the bottle top 1, a hole is arranged in the middle of the top end of the bottle top 1, a through pipe 9 is arranged in the hole of the bottle top 1, a sealing gasket one 15 is arranged on the inner top wall of the bottle top 1, a sealing gasket three 19 is arranged in the middle of the top end of the bottle top 1, the middle of the sealing gasket three 19 is arranged on the outer wall of the through pipe 9, a sleeve 4 is arranged on the outer wall of the through pipe 9, a pressure gauge 5 is arranged at one end of the sleeve 4, an external thread 10 is arranged at the other end of the sleeve 4, limiting blocks 13 are fixedly connected to both sides of the middle of the outer wall of the sleeve 4, a switch assembly is arranged on the side wall of the limiting block 13, the switch assembly includes a rotary cover 6, a turning handle 20 is fixedly connected to the top end of the rotary cover 6, a rotating shaft 17 is fixedly connected to the bottom end of the rotary cover 6, the outer wall of the rotating shaft 17 passes through the sleeve 4 and is fixedly connected to a sphere 18, a hole is opened in the middle of the sphere 18, sealing gaskets two 16 are arranged on both sides of the sphere 18, the outer walls of the sealing gaskets two 16 are arranged on the inner wall of the sleeve 4, and an internal thread 14 is arranged on the inner wall of the sleeve 4.

[0023] Specifically, when the user is using it, the whole can be lifted by the handle 3 and placed at a designated position. The external thread 10 on the sleeve 4 and the internal thread 14 are thread-connected to connect the external pipeline. It can be connected to the sleeve 4 according to different types of pipelines. The bottom end of the outer wall of the sleeve 4 is connected to the through pipe 9, and the through pipe 9 is connected to the bottle top 1. The gas is also transported through the through pipe 9 into the inside of the sleeve 4. To avoid leakage at the joint, a third sealing gasket 19 is installed at the middle top end of the bottle top 1, and a first sealing gasket 15 is installed on the inner top wall of the bottle top 1 to prevent gas leakage. When the gas enters the sleeve 4 from the through pipe 9, the user can open or close the gas transportation by turning the switch assembly. The switch assembly includes a screw cap 6, a turning handle 20, a rotating shaft 17, a sphere 18, and a second sealing gasket 16. When the switch assembly needs to transport gas when it is closed, it can be driven by turning the turning handle 20. The turning handle 20 drives the screw cap 6 to rotate, thereby driving the rotating shaft 17 to rotate, and then driving the sphere 18 to rotate. The rotation of the sphere 18 drives the two second sealing gaskets 16 to rotate. The second sealing gasket 16 is made of soft rubber and can be fixed on both sides of the pipe wall of the sleeve 4 when rotating. When the screw cap 6 rotates to a certain angle, it will be limited by the two limit blocks 13. After the sphere 18 rotates, the gas can be transported through the hole in the middle. When it needs to be closed, turning the turning handle 20 in the opposite direction can close the transportation channel, and the second sealing gasket 16 can seal the leakage of the pipeline gas. Through the switch assembly, the first sealing gasket 15 and the third sealing gasket 19, the effect of avoiding leakage can be achieved. It can not only increase the seal to avoid leakage, but also buffer vibration, ensure the stability of the pressure in the bottle, prevent the escape of toxic gases, and guarantee the breathing safety of the people in the vehicle, solve the problem of leakage of the liquefied gas cylinder, and reduce energy waste.

[0024] Refer to Figures 1 - 2 , a bottle body 2 is provided at the bottom end of the bottle top 1. A protective ring 8 is provided on the outer wall of the bottle body 2, and a fixing seat 7 is provided on the outer wall of the bottle body 2. The outer wall of the protective ring 8 is arranged on one side of the fixing seat 7. A honeycomb sleeve 11 is provided on the inner wall of the bottle body 2. A number of honeycomb holes 12 are provided on the outer wall of the honeycomb sleeve 11, and the outer shape of the honeycomb holes 12 is hexagonal.

[0025] Specifically, the user can place the fixing base 7 in the vehicle or the trunk. Then, through the handle 3, the bottle body 2 is placed in the groove of the fixing base 7 for fixation to prevent it from falling during driving. The protective ring 8 installed on the outer wall of the bottle body 2 can protect the bottle body 2. The protective ring 8 wraps around the outside of the bottle body 2 and can absorb and disperse the collision energy when the vehicle undergoes a minor collision, protecting the bottle body 2 from damage. Inside the bottle body 2, there is a honeycomb sleeve 11, which is composed of multiple layers of buffer materials with a honeycomb structure. This honeycomb structure can further absorb energy through its own compression deformation when subjected to a large impact force, reducing the impact on the bottle body 2 and preventing leakage caused by the bottle body 2 cracking or the interface loosening due to collision. Through the protective ring 8 and the honeycomb sleeve 11, the anti-collision protection effect can be achieved. It can not only protect the outer shell but also buffer and reduce the impact, reduce the risk of the bottle body 2 cracking, protect the safety of the key components of the bottle body 2, solve the problem of poor anti-collision protection, and ensure that the gas does not leak.

[0026] Working principle: The pipeline can be connected to the bottle top 1 through the through pipe 9, and the gas is also transported to the inside of the sleeve 4 through the through pipe 9. To avoid leakage at the joint, a sealing gasket three 19 is installed at the middle top of the bottle top 1, and a sealing gasket one 15 is installed on the inner top wall of the bottle top 1 to block the leakage of the gas. When the gas enters the sleeve 4 from the through pipe 9, the user can drive it by turning the rotating handle 20. The rotating handle 20 drives the screw cap 6 to rotate, thereby driving the rotating shaft 17 to rotate, and then driving the sphere 18 to rotate. The rotation of the sphere 18 drives the two sealing gaskets two 16 to rotate. The sealing gasket two 16 is made of soft rubber, and when rotating, the sealing gasket two 16 can be fixed on both sides of the pipe wall of the sleeve 4. The protective ring 8 wraps around the outside of the bottle body 2 and can absorb and disperse the collision energy when the vehicle undergoes a minor collision, protecting the bottle body 2 from damage. The honeycomb sleeve 11 is composed of multiple layers of buffer materials with a honeycomb structure. This honeycomb structure can further absorb energy through its own compression deformation when subjected to a large impact force, reducing the impact on the bottle body 2.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
