Description

Technical Field

[0001] This utility model belongs to the field of steel cylinder technology, specifically relating to an anti-corrosion structure for liquefied gas steel cylinders. Background Technology

[0002] Gas cylinders are steel cylinders used to store high-pressure oxygen, coal gas, liquefied petroleum gas, etc. Gas cylinders generally contain permanent gases, liquefied gases, or mixtures of gases. Gas cylinder management urgently needs improvement among gas cylinder filling units, gas cylinder inspection units, gas cylinder users (including factories, laboratories, hospitals, schools, disease control centers, electronics rooms, clean rooms, industrial institutions, etc.), bottled gas distributors, and gas cylinder dealers. Safety management of the transportation and storage of gas cylinders should be strengthened.

[0003] According to Chinese patent publication number CN220228727U, a corrosion-resistant welded steel cylinder is disclosed, comprising a cylinder body for loading gas, a handle at the top of the cylinder body, and a gas pipe connected to the top of the cylinder body. An outer coating is fixedly disposed on the outer surface of the cylinder body, an intermediate coating is disposed inside the outer coating, and a base coating is fixedly disposed inside the intermediate coating. A cavity is formed inside the outer coating. This corrosion-resistant welded steel cylinder, through the application of a multi-layer coating design consisting of a polymer ceramic wear-resistant coating layer, a first hyperbranched epoxy modified resin material layer, a fluorocarbon resin layer, a second hyperbranched epoxy modified resin material layer, a third hyperbranched epoxy modified resin material layer, and a polyurethane coating, significantly improves the device's protective performance. This results in excellent corrosion resistance, providing convenience for users, enhancing the device's practicality, and meeting user needs.

[0004] The aforementioned patent employs a multi-layer coating design, which improves the overall corrosion resistance of the material solution. However, the steel cylinder itself is exposed, and prolonged use will lead to the accumulation of dust and impurities on the exterior, inevitably causing damage to the outer wall of the cylinder. Utility Model Content

[0005] The purpose of this invention is to provide an anti-corrosion structure for liquefied petroleum gas cylinders to solve the problem of cylinder outer wall protection in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A corrosion-resistant structure for a liquefied petroleum gas (LPG) cylinder includes a cylinder with a base at the bottom. The base has several rectangular grooves on its surface, and a support assembly is installed in each of the rectangular grooves. A protective plate is installed on the support assembly, and the protective plate is located on the outside of the cylinder. An air bladder is provided on the inner wall of the protective plate.

[0008] Furthermore, the support component includes an arc-shaped support block, an arc-shaped track is provided inside the arc-shaped support block, the arc-shaped track fits the bottom of the protective plate, a support arm is fixed to the bottom of the arc-shaped support block, a positioning shaft is installed at the bottom of the support arm, a rectangular block is provided on one side of the positioning shaft, and the rectangular block and the rectangular groove cooperate with each other.

[0009] Furthermore, one end of the rectangular block is provided with an adhesive block, which is arc-shaped. The arc-shaped adhesive block can fit well against the outer wall of the base. Thus, when the rectangular block is installed and inserted, the adhesive block will abut against the outer wall of the base, thereby indicating the insertion position of the rectangular block as the maximum insertion distance, without the need to deliberately control the insertion distance of the rectangular block.

[0010] Furthermore, the bottom of the arc-shaped track is provided with a T-groove, and the bottom of the protective plate is provided with an arc-shaped slider that cooperates with the T-groove.

[0011] Furthermore, a circular hole is provided on one side of the inner wall of the arc-shaped track, and a raised ball is provided on the outer wall of the protective plate, with the raised ball positioned in the center of the arc-shaped slider. The raised ball has a certain compressive deformation capability, which is reflected by the tough plastic material properties; by rotating the protective plate, when the arc-shaped slider is fitted into the T-slot, its raised ball will be stuck inside the circular hole, generating some resistance or a "click" sound. This allows the installer to interact during installation to determine whether the arc-shaped slider is installed in the correct position.

[0012] The technical solution of this utility model has the following beneficial effects:

[0013] 1. The airbag can fill the gap between the protective plate and the cylinder, thereby preventing external impurities or other contaminants from contacting the outer wall of the cylinder. This keeps the cylinder surface clean and prevents corrosion or damage caused by the accumulation of impurities, thus extending the service life of the cylinder.

[0014] 2. The softness and elasticity of the airbag can also cushion the impact and friction on the gas cylinder to a certain extent, reducing scratches or dents on the cylinder surface caused by accidental collisions, further enhancing the physical protection of the gas cylinder. Through the design of the protective plate and airbag, protection is provided during both transportation and use.

[0015] 3. Rotate the protective plate, and the arc-shaped slider will gradually enter the T-slot to lock in place. In this way, the protective plate and the arc-shaped support block become one unit, which improves the overall stability of the installation and makes the whole unit easy to disassemble and install.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] Example 1:

[0025] refer to Figures 1-3 A corrosion-resistant structure for a liquefied petroleum gas cylinder includes a cylinder 10, a base 101 at the bottom of the cylinder 10, a plurality of rectangular grooves 102 on the surface of the base 101, a support assembly 30 installed in the rectangular grooves 102, a protective plate 20 installed on the support assembly 30, the protective plate 20 being disposed on the outside of the cylinder, and an airbag 201 being provided on the inner wall of the protective plate 20.

[0026] In the above scheme, the protective plate 20 has a circular structure, and its diameter is larger than that of the cylinder 10. During installation, the protective plate 20 is fitted over the outside of the cylinder 10, with its bottom support contacting the support assembly 30 for initial positioning. The outer wall of the protective plate 20 is equipped with an air nozzle 202. An air pump or other inflation device is connected to the air nozzle 202 to inflate the airbag 201. The airbag 201 fills the gap between the protective plate 20 and the cylinder 10, thus preventing external impurities or other contaminants from contacting the outer wall of the cylinder 10. This keeps the cylinder surface clean and prevents corrosion or damage caused by impurity accumulation, thereby extending the cylinder's service life. When inflated, the airbag 201 increases the contact friction with the outer wall of the cylinder 10, further improving the stability of the protective plate 20 on the cylinder's outer wall and preventing it from falling off.

[0027] Meanwhile, the softness and elasticity of the airbag 201 can also buffer the impact and friction of the external environment on the gas cylinder to a certain extent, reducing scratches or dents on the surface of the gas cylinder caused by accidental collisions, further enhancing the physical protection of the gas cylinder 10; the protective plate 20 provides protection for the airbag 201, thereby preventing sharp objects from touching the airbag 201. Through the setting of the protective plate 20 and the airbag 201, protection functions can be provided during both transportation and use.

[0028] Further reference Figures 2-5 The support component 30 includes an arc-shaped support block 301, an arc-shaped track 302 is provided inside the arc-shaped support block 301, the arc-shaped track 302 fits the bottom of the protective plate 20, a support arm 304 is fixed to the bottom of the arc-shaped support block 301, a positioning shaft 305 is installed at the bottom of the support arm 304, a rectangular block 307 is provided on one side of the positioning shaft 305, and the rectangular block 307 cooperates with the rectangular groove 102.

[0029] In a further implementation, the rectangular block 307 is inserted into the rectangular groove 102. The plug-in installation method facilitates disassembly. The rectangular block 307 is stable in the rectangular groove 102, preventing the positioning shaft 305 from rotating. The direction of the support arm 304 is vertically upward, meaning that the bottom of the protective plate 20 will be supported in the arc-shaped track 302 during installation. The arc-shaped track 302, with its arc-shaped structure, fits well against the lower end of the protective plate 20, providing good stability. Note that: to install the protective plate 20 using the support components 30, two or more support components 30 are required to support the bottom of the protective plate 20.

[0030] Preferred Solution Reference Figure 3 and Figure 4The rectangular block 307 has a fitting block 306 at one end, and the fitting block 306 is arc-shaped. The arc-shaped fitting block 306 can fit well against the outer wall of the base 101. So when the rectangular block 307 is installed and inserted, the fitting block 306 will abut against the outer wall of the base 101, thus indicating that the insertion position of the rectangular block 307 is the maximum insertion distance, without the need to deliberately control the insertion distance of the rectangular block 307.

[0031] Example 2:

[0032] refer to Figure 4 and Figure 5 The bottom of the arc track 302 is provided with a T-groove 303, and the bottom of the protective plate 20 is provided with an arc-shaped slider 203 that cooperates with the T-groove 303.

[0033] In the above scheme, when installing the protective plate 20, the arc-shaped slider 203 is staggered from the arc-shaped support block 301, that is, the bottom of the protective plate 20 is supported on the arc-shaped track 302; then the protective plate 20 is rotated, and the arc-shaped slider 203 will gradually enter the T-groove 303 to complete the locking. In this way, the protective plate 20 and the arc-shaped support block 301 are integrated, which improves the overall stable installation; similarly, when it is necessary to disassemble the protective plate 20, it is only necessary to rotate the protective plate 20 to make the arc-shaped slider 203 disengage from the T-groove 303, so as to facilitate the disassembly and removal of the protective plate 20.

[0034] Further reference Figure 4 and Figure 5 A circular hole 308 is provided on one side of the inner wall of the arc-shaped track 302, and a raised ball 204 is provided on the outer wall of the protective plate 20. The raised ball 204 is located in the center position of the arc-shaped slider 203.

[0035] In a further implementation scheme, the raised ball 204 has a certain compressive deformation capability, which is reflected by the tough plastic material properties; by rotating the protective plate 20, when the arc-shaped slider 203 is fitted in the T-groove 303, its raised ball 204 will be stuck inside the round hole 308, which will generate some resistance or a "click" sound. This allows the installer to interact during installation and know whether the arc-shaped slider 203 is installed in the correct position.

[0036] The specific implementation process of this utility model is as follows:

[0037] First, when installing the protective plate 20, it is placed over the outside of the gas cylinder 10, with the bottom support of the protective plate 20 contacting the arc-shaped track 302. Note: The arc-shaped slider 203 is offset from the arc-shaped support block 301, meaning the bottom of the protective plate 20 is supported on the arc-shaped track 302. Then, rotate the protective plate 20, and the arc-shaped slider 203 will gradually enter the T-groove 303 to lock in place. Similarly, when it is necessary to remove the protective plate 20, simply rotate the protective plate 20 to disengage the arc-shaped slider 203 from the T-groove 303, and the protective plate 20 can be easily removed.

[0038] Finally, an air pump or other inflation device is connected to the air nozzle 202 to inflate the airbag 201, which can fill the gap between the protective plate 20 and the cylinder 10.

[0039] The above embodiments are merely exemplary models of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection.
