Description

Technical Field

[0001] This utility model relates to the field of gas cylinder technology, and in particular to a high-strength explosion-proof cylinder. Background Technology

[0002] Liquefied petroleum gas (LPG) cylinders are containers used to store LPG. They are usually made of thick steel, have high strength, and good explosion-proof performance. Due to the limited availability of natural gas in rural areas, they are widely used in rural areas.

[0003] A search revealed that the utility model patent with authorization announcement number CN222047373U discloses a thickened explosion-proof liquefied petroleum gas cylinder. This device can protect the cylinder's exterior during use, preventing damage from external forces and ensuring the cylinder's stability. It solves the problem that external forces can easily damage the cylinder's exterior, causing internal leakage and impacting the surrounding environment.

[0004] Although the aforementioned gas cylinders have improved strength and explosion-proof performance through the external protective structure, during actual assembly, the cylinders need to be lifted and then inserted through the top opening of the external protective structure, which is difficult and laborious. In addition, the addition of the external protective structure will further increase the weight of the cylinders. When it is necessary to refill the cylinders during actual use, since the cylinders are usually placed in the kitchen and the refilling operation needs to be carried out outdoors near the cylinders, the difficulty of moving the cylinders is further increased.

[0005] Therefore, it is necessary to invent a high-strength explosion-proof steel cylinder to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a high-strength explosion-proof steel cylinder that effectively reduces the lifting height during cylinder assembly, thereby reducing the assembly difficulty and saving manpower. Furthermore, when the cylinder needs to be inflated, the fixed protective mechanism can be separated to reduce the overall weight and facilitate convenient transfer of the cylinder. This makes it more convenient in actual use, solving the problem mentioned in the background art where, during actual assembly, the cylinder needs to be lifted and then inserted through the top opening of the external protective structure, which is difficult and laborious. Additionally, the addition of the external protective structure further increases the weight of the cylinder. Moreover, in actual use, when the cylinder needs to be inflated, since it is usually placed in the kitchen and the inflation operation needs to be carried out outdoors near the cylinder, the difficulty of transferring the cylinder is further increased.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a high-strength explosion-proof steel cylinder, comprising:

[0008] A fixed protective mechanism is provided for protection of the cylinder body from the outside.

[0009] A dynamic protective mechanism includes a protective plate fitted to the right opening of a U-shaped protective cover. A cylinder tray for placing the cylinder body is fixedly mounted on the top left side of the protective plate. A handle A is fixedly mounted on the top right side of the protective plate, and two casters are rotatably connected to the bottom right side via pins. A slot adapted to an insert is opened on the top left side of the protective plate, and a locking groove is opened on the bottom inner side of the slot. Locking rods are slidably inserted vertically through both ends of the top of the protective plate, with the bottom ends of the locking rods extending into the inner side of adjacent locking grooves. A handle B is fixedly mounted on the top ends of both locking rods.

[0010] The cylinder body is used to store liquefied natural gas.

[0011] According to at least one embodiment of the high-strength explosion-proof steel cylinder of the present disclosure, the fixed protection mechanism includes a U-shaped protective cover, a supporting base plate is fixedly provided on the bottom inner side of the U-shaped protective cover, and a U-shaped configuration block is fixedly provided on the bottom outer side of the U-shaped protective cover.

[0012] According to at least one embodiment of the high-strength explosion-proof steel cylinder of the present disclosure, an insert block is fixedly provided at the middle of both ends of the right side of the U-shaped protective cover, and a locking channel is provided through the top of the insert block in the vertical direction.

[0013] According to at least one embodiment of the high-strength explosion-proof steel cylinder of the present disclosure, the dynamic protection mechanism further includes a steel cylinder positioning groove formed at the top of the steel cylinder positioning groove and adapted to the bottom of the steel cylinder body.

[0014] According to at least one embodiment of the high-strength explosion-proof steel cylinder of the present disclosure, the dynamic protection mechanism further includes a limiting slide groove opened on the top left side of the protective plate, and a limiting slider that is fixedly connected to an adjacent locking rod is slidably arranged in the vertical direction inside the positioning groove of the steel cylinder.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a dynamic protective mechanism. When the cylinder needs to be inflated, pulling handle B upwards moves the locking lever out of the locking channel to release the lock. Then, pulling the protective plate outwards via handle A moves the cylinder body out of the U-shaped protective cover via the cylinder tray. At this point, handle B drives the protective plate to rotate clockwise around the pin on the moving wheel until both moving wheels are fully grounded. Pulling handle B again allows the dynamic protective mechanism to be easily moved via the moving wheels. Compared to existing technologies, this invention effectively reduces the lifting height of the cylinder body during assembly, thereby reducing assembly difficulty and saving manpower. Furthermore, when the cylinder needs to be inflated, the fixed protective mechanism can be separated to reduce the overall weight and facilitate easy transfer of the cylinder body, making it more convenient in actual use.

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., as in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a high-strength explosion-proof steel cylinder according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the fixed protection mechanism 1 of a high-strength explosion-proof steel cylinder according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the dynamic protection mechanism 2 of a high-strength explosion-proof steel cylinder according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the high-strength explosion-proof steel cylinder disclosed herein may include components such as a fixed protection mechanism 1, a dynamic protection mechanism 2, and a steel cylinder body 3.

[0030] It should be noted that the cylinder body 3 is made of steel, which has high strength and good explosion-proof performance. It is existing technology, so this application will not elaborate on its specific structure here.

[0031] like Figure 2 As shown in this disclosure, the fixed protective mechanism 1 includes a U-shaped protective cover 11. A supporting base plate 12 is fixedly installed on the bottom inner side of the U-shaped protective cover 11. A U-shaped configuration block 13 is fixedly installed on the bottom outer side of the U-shaped protective cover 11. Insert blocks 14 are fixedly installed at the middle of both ends of the right side of the U-shaped protective cover 11. A locking channel 15 is provided through the top of the insert block 14 in the vertical direction.

[0032] Therefore, the U-shaped protective cover 11 can be used to provide large-area protection for the cylinder body 3 from the outside, thereby preventing the surface of the cylinder body 3 from being directly bumped during use. The support base plate 12 and the U-shaped configuration block 13 can lower the overall center of gravity of the fixed protection mechanism 1, while increasing the contact area between the fixed protection mechanism 1 and the ground, thereby increasing the stability of the fixed protection mechanism 1 after it is placed.

[0033] like Figure 3 As shown, in a preferred embodiment, the dynamic protective mechanism 2 includes a protective plate 21 that fits into the right opening of the U-shaped protective cover 11. A cylinder tray 22 for placing the cylinder body 3 is fixedly installed on the top left side of the protective plate 21. A handle A23 is fixedly installed on the top right side of the protective plate 21, and two movable wheels 24 are rotatably connected to the bottom right side by a pin. A slot 25 that matches the insert block 14 is opened on the top left side of the protective plate 21. A locking groove 26 is opened on the bottom inner side of the slot 25. Locking rods 27 are slidably installed through both ends of the top of the protective plate 21 in the vertical direction. The bottom end of the locking rods 27 extends to the inner side of the adjacent locking groove 26. A handle B28 is fixedly installed on the top of the two locking rods 27.

[0034] Therefore, when assembling the cylinder body 3, the cylinder body 3 is slightly lifted and placed on top of the cylinder tray 22. Then, the handle B28 is pulled up, which causes the handle B28 to move the locking rod 27 upward. Then, the protective plate 21 is pushed by the handle A23, which causes the protective plate 21 to move the cylinder body 3 through the cylinder tray 22 until the insert 14 enters the inner side of the adjacent slot 25. Finally, the handle B28 is released. Under the action of gravity, the handle B28 drives the locking rod 27 through the adjacent locking channel 15 and into the inner side of the adjacent locking groove 26 to achieve locking. At this time, the protective plate 21, together with the U-shaped protective cover 11, provides protection for the outside of the cylinder body 3.

[0035] When it is necessary to inflate the cylinder body 3, pull the handle B28 upwards, thereby moving the locking rod 27 out from the inside of the locking channel 15 to release the lock. Then, pull the protective plate 21 outwards through the handle A23, thereby moving the cylinder body 3 out from the inside of the U-shaped protective cover 11 through the cylinder tray 22. At this time, the protective plate 21 is rotated clockwise around the pin on the moving wheel 24 by the handle B28 until the two moving wheels 24 are completely grounded. Then, when the handle B28 is pulled, the entire moving protective mechanism 2 can be easily moved by the moving wheels 24.

[0036] like Figure 3 The dynamic protection mechanism 2 also includes a cylinder positioning groove 221 located at the top of the cylinder positioning groove 221 and adapted to the bottom of the cylinder body 3, so as to position the cylinder body 3 through the cylinder positioning groove 221, making the cylinder body 3 more stable. The dynamic protection mechanism 2 also includes a limiting slide groove 211 located at the top left side of the protective plate 21. A limiting slider 271 fixedly connected to the adjacent locking rod 27 is slidably provided on the inner side of the cylinder positioning groove 221 in the vertical direction, so that when the locking rod 27 moves upward, it drives the limiting slider 271 to move upward synchronously. The limiting slide groove 211 limits the limiting slider 271, thereby preventing the locking rod 27 from directly coming off the top of the protective plate 21.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
