Description

Technical Field

[0001] The utility model belongs to the field of machinery and relates to an alternating buffer protection gas cylinder. Background Art

[0002] Gas cylinders have a wide range of uses. They can be used as oxygen cylinders and argon cylinders. Except that the oxygen cylinder body is painted blue and the argon cylinder body is painted black, the bottle body structure is basically the same. The protection of gas cylinders is very critical. The current protection structure is mainly at the top. The top protection structure generally has a protective cover. This structure is the most common in current gas cylinders. Some of our company's patented technologies are also innovatively improved based on this protective cover. For example, our company applied for a utility model patent for an argon cylinder based on a head anti-collision structure on June 9, 2022. Although major improvements have been made to the traditional protective cover, there is still a risk of collision at the valve connection. Other improvements to the protective cover still have shortcomings in protection performance.

[0003] In order to solve the above problems, this application is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an alternating buffer protection gas cylinder in view of the above-mentioned problems existing in the prior art. The alternating buffer protection gas cylinder optimizes the top protection structure of the bottle body and solves the problems such as insufficient optimization of the top protection structure of the existing gas cylinder.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] An alternating buffer protection gas cylinder comprises a bottle body, a valve and a top protection structure, the top of the bottle body has a connecting portion protruding outward, and the bottom of the valve is screwed to the connecting portion, and is characterized in that the top protection structure is a three-layer structure, including a top inner layer, a top middle layer and a top outer layer, the top outer layer and the top inner layer are both made of soft materials, the top middle layer is made of hard material, the top middle layer is located between the top inner layer and the top outer layer, the top inner layer is an arc-shaped structure and is sleeved on the arc-shaped outer wall of the top of the bottle body, the top outer layer is sleeved on the outer wall of the top middle layer, the top middle layer is cylindrical as a whole and the lower end is fixed to the outer wall of the bottle body, the inner wall of the top middle layer has an inner baffle cover with an arc-shaped structure that fits the outer wall of the top inner layer, and the upper end of the top middle layer extends upward to wrap the valve.

[0007] The connection part and valve in this scheme are both existing technologies, and the structure will not be described in detail. The special feature of this scheme is that it has an optimized top protection structure, which has three layers: inner, middle and outer. The top inner layer and the top outer layer are made of the same material. The top outer layer directly contacts the impact surface, and the top inner layer directly contacts the outer wall of the bottle body. Therefore, the soft material has a good buffering effect, and the top middle layer in the middle is made of hard material, forming a soft-hard-soft interval buffering structure. The impact force is first buffered by the top outer layer, and then most of the impact force is formed in the top middle layer. The top middle layer has a hard protective effect, and then it is transmitted to the top inner layer for buffering. The alternating buffering structure can achieve a good protection for the bottle body. This protection effect cannot be achieved by a fully soft structure or a fully hard structure. The fully soft structure is easy to directly cause bumps to the bottle body under a large impact force, and the fully hard structure has a poor buffering effect. The alternating structure in this scheme not only guarantees the buffering effect but also forms a rigid requirement, and the structural design is ingenious. An inner baffle is designed inside the top middle layer. The design of the inner baffle is to better fix the top inner layer, so that the top inner layer presses against the top wall of the bottle body, and the top inner layer plays a better role in buffering and protection. In addition, the upper end of the top middle layer extends upward to wrap around the valve, which also protects the valve and the connection. When the top middle layer is hit by a rollover, the top middle layer protects it. The top protective structure in this gas cylinder not only protects the top of the bottle body, but also protects the valve and the connection through the top middle layer extension structure.

[0008] In the above-mentioned alternating buffer protection gas cylinder, the lower end of the top middle layer is threadedly connected to the outer wall of the bottle body.

[0009] In the above-mentioned alternating buffer protection gas cylinder, the length of the top middle layer extending out of the top outer layer is greater than the length of the top outer layer.

[0010] Extending the extension length can reduce the impact on the top of the bottle body, and when the upper end of the top middle layer is hit, the impact force transmitted to the lower end can be reduced.

[0011] In the above-mentioned alternating buffer protection gas cylinder, at least one operation opening from top to bottom is opened at the upper end of the top middle layer.

[0012] In practice, two operating ports may be provided, and the operating ports may be rectangular. The operating ports are provided to facilitate operation of the valve, such as connection of a delivery pipe.

[0013] The above-mentioned alternating buffer protection gas cylinder also includes a bottom protection structure, which includes a bottom inner sleeve, a bottom middle sleeve and a bottom outer sleeve, all of which have open upper ends. The bottom inner sleeve and the bottom outer sleeve are both made of soft materials, and the bottom middle sleeve is made of hard material. The bottom inner sleeve is sleeved on the outer wall of the bottom of the bottle body, the bottom middle sleeve is located between the bottom inner sleeve and the bottom outer sleeve, and the bottom outer sleeve is sleeved on the outer wall of the bottom middle sleeve.

[0014] Since the potential safety hazard of gas cylinders tipping over occurs frequently, the bottom protection of gas cylinders is often neglected. However, when gas cylinders are unloaded from transport vehicles, there are also many cases where the bottom of the gas cylinder hits the ground and sprays out, causing casualties. Therefore, it is very necessary to innovate and improve the double-end safety of gas cylinders. The bottom protection structure is also divided into three layers: inner, middle, and outer. Its protection principle is similar to the inner, middle, and outer three-layer protection of the top protection structure. Both are achieved through a soft-hard-soft three-layer structure, so that the bottom of the gas cylinder or the outer wall of the bottom can be fully protected when hit, greatly avoiding the safety risks caused by bottom impact.

[0015] In the above-mentioned alternating buffer protection gas cylinder, the top inner layer, the top outer layer, the bottom inner sleeve and the bottom outer sleeve are all made of rubber material.

[0016] Rubber material has good cushioning effect.

[0017] In the above-mentioned alternating buffer protection gas cylinder, the top middle layer and the bottom middle sleeve are made of stainless steel material.

[0018] Stainless steel material has high hardness.

[0019] In the above-mentioned alternating buffer protection gas cylinder, the thickness of the top inner layer, the top outer layer, the bottom inner sleeve, the bottom outer sleeve, the top middle layer and the bottom middle sleeve are not less than 2 mm.

[0020] This size structure enables the corresponding layer or set to fully function.

[0021] Compared with the prior art, this alternating buffer protection gas cylinder has the following advantages:

[0022] 1. The top protective structure of the alternating buffer protection gas cylinder can achieve good protection for the bottle body through the soft-hard-soft alternating buffer structure. At the same time, the top middle layer extends upward to protect the valve and the connection part.

[0023] 2. The bottom protection structure of the alternating buffer protection gas cylinder also adopts a soft-hard-soft alternating buffering method, so that the bottom of the gas cylinder or the outer wall of the bottom can be fully protected when it is hit, thereby avoiding the safety risks caused by bottom impact to a great extent.

[0039] like Figures 1 to 3As shown, the alternating buffer protection gas cylinder includes a bottle body 1, a valve 2 and a top protection structure. The top of the bottle body 1 has a connection portion 1a protruding outward, the bottom of the valve 2 is screwed to the connection portion 1a, and the top protection structure is a three-layer structure, including a top inner layer 3, a top middle layer 4 and a top outer layer 5. The top outer layer 5 and the top inner layer 3 are both made of soft materials, and the top middle layer 4 is made of hard materials. The top middle layer 4 is located between the top inner layer 3 and the top outer layer 5. The top inner layer 3 is an arc-shaped structure and is sleeved on the top arc-shaped outer wall of the bottle body 1. The top outer layer 5 is sleeved on the outer wall of the top middle layer 4. The top middle layer 4 is cylindrical as a whole and the lower end is fixed on the outer wall of the bottle body 1. The inner wall of the top middle layer 4 has an inner baffle 4a with an arc-shaped structure that fits the outer wall of the top inner layer 3. The upper end of the top middle layer 4 extends upward to wrap the valve 2. The connection portion 1a and the valve 2 in this solution are both existing technologies, and the structure is not repeated. The special feature of this solution is that it has an optimized top protective structure, which has three layers: inner, middle and outer. The top inner layer 3 and the top outer layer 5 are made of the same material. The top outer layer 5 directly contacts the impact surface, and the top inner layer 3 directly contacts the outer wall of the bottle body 1. Therefore, the soft material has a good buffering effect, and the top middle layer 4 in the middle is made of hard material, forming a soft-hard-soft interval buffering structure. The impact force is first buffered by the top outer layer 5, and then most of the impact force is formed in the top middle layer 4, and the top middle layer 4 has a hard protective effect, and then transmitted to the top inner layer 3 for buffering. The alternating buffering structure can achieve a good protection for the bottle body 1, and this protection effect cannot be achieved by a fully soft structure or a fully hard structure. The fully soft structure is easy to directly cause bumps to the bottle body 1 under a large impact force, and the fully hard structure has a poor buffering effect. The alternating structure in this solution not only guarantees the buffering effect but also forms a rigid requirement, and the structural design is ingenious. An inner baffle 4a is designed inside the top middle layer 4. The design of the inner baffle 4a is to better fix the top inner layer 3, so that the top inner layer 3 presses the top wall of the bottle body 1, so that the top inner layer 3 can better play a buffering and protective role. In addition, the upper end of the top middle layer 4 extends upward to wrap the valve 2, which also protects the valve 2 and the connecting part 1a. When the top middle layer 4 is hit by the rollover, the top middle layer 4 achieves a protective effect. The top protective structure in this gas cylinder not only protects the top of the bottle body 1, but also protects the valve 2 and the connecting part 1a through the extension structure of the top middle layer 4.

[0040] The lower end of the top middle layer 4 is threadedly connected to the outer wall of the bottle body 1. The length of the top middle layer 4 extending out of the top outer layer 5 is greater than the length of the top outer layer 5. Extending the extended length can reduce the impact on the top of the bottle body 1, and when the upper end of the top middle layer 4 is hit, the impact force can be reduced from being transmitted to the lower end. The upper end of the top middle layer 4 is provided with two operation ports 4b from top to bottom. In practice, two operation ports 4b can be provided, and the operation ports 4b can be rectangular. The operation ports 4b are provided to facilitate the operation of the valve 2, such as connecting a delivery pipe. It also includes a bottom end protection structure, which includes a bottom inner sleeve 6, a bottom middle sleeve 7 and a bottom outer sleeve 8, all of which have openings at the upper ends. The bottom inner sleeve 6 and the bottom outer sleeve 8 are both made of soft materials, and the bottom middle sleeve 7 is made of hard materials. The bottom inner sleeve 6 is sleeved on the outer wall of the bottom of the bottle body 1, and the bottom middle sleeve 7 is located between the bottom inner sleeve 6 and the bottom outer sleeve 8, and the bottom outer sleeve 8 is sleeved on the outer wall of the bottom middle sleeve 7. Since the potential safety hazard of gas cylinders tipping over occurs frequently, the protection of the bottom of the gas cylinders is often neglected. However, when the gas cylinders are unloaded from the transport vehicle, the bottom of the gas cylinders hits the ground and sprays, causing casualties. Therefore, it is very necessary to innovate and improve the double-end safety of the gas cylinder. The bottom protection structure is also divided into three layers: inner, middle and outer. Its protection principle is similar to the inner, middle and outer three-layer protection of the top protection structure. Both are achieved through a soft-hard-soft three-layer structure, so that the bottom of the gas cylinder or the outer wall of the bottom can be fully protected when it is hit, greatly avoiding the safety risks caused by the bottom impact. The top inner layer 3, the top outer layer 5, the bottom inner sleeve 6 and the bottom outer sleeve 8 are all made of rubber materials. Rubber materials have good buffering effects. The top middle layer 4 and the bottom middle sleeve 7 are made of stainless steel materials. Stainless steel materials have high hardness. The thickness of the top inner layer 3, the top outer layer 5, the bottom inner sleeve 6, the bottom outer sleeve 8, the top middle layer 4 and the bottom middle sleeve 7 is not less than 2mm. This size structure enables the corresponding layers or sleeves to play their full role.
