Description

Technical Field

[0001] This utility model relates to the field of protective box technology, and in particular to a multifunctional gas cylinder protective box. Background Technology

[0002] A gas cylinder is a type of portable pressure vessel with a bottle-shaped main structure, typically filled with gas (compressed gas, liquefied gas, dissolved or adsorbed gas, etc.). Gas cylinders have a wide range of applications; they are indispensable in both production and daily life.

[0003] Gas cylinders are pressure vessels that pose an explosion hazard. The media they contain are typically flammable, explosive, toxic, or highly corrosive. Their operating environments are more complex and harsher than those of other pressure vessels due to their mobility, repeated filling, the presence of unsettled operators, and changing environmental conditions. An explosion or leak in a gas cylinder often results in fire or poisoning, or even catastrophic accidents, causing severe property damage, personal injury, and environmental pollution.

[0004] Patent document CN213567147U discloses a gas cylinder box for on-site testing. This utility model includes a box body, a top cover, a front door, and a pull rod. The box body is hollow inside for securing gas cylinders, and the top cover is installed on the top of the box body. The front door is installed at the front of the box body; it is opened when loading and unloading gas cylinders and closed after loading and unloading. A pull rod is installed at the back of the box body. This utility model has a simple structure, is easy to operate, and can safely and conveniently transport gas cylinders to the testing site.

[0005] As in the prior art of the aforementioned patent, the gas cylinder storage box uses clamps to fix the gas cylinders inside. However, this fixing method is cumbersome to disassemble and can only be used to fix gas cylinders of a fixed size. It cannot fix gas cylinders of different sizes. Furthermore, the inside of the gas cylinder box can only store gas cylinders and cannot hold other appliances, which has certain limitations. Utility Model Content

[0025] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] Reference Figure 1-2A multifunctional gas cylinder protective box includes a box body 2, with a lid 1 hinged to the box body 2. Both the box body 2 and the lid 1 are equipped with casters 102 at their bottom ends. The interior of the box body 2 includes two first-size storage compartments 5, one second-size storage compartment 6, and one tool storage compartment 301. Each of the first-size storage compartments 5 and the second-size storage compartment 6 has two fixing straps 7 inside. A locking fastener 8 is provided between the lid 1 and the box body 2. Both the outer shells of the box body 2 and the lid 1 are made of aluminum alloy, serving to protect the equipment inside the box; they are lightweight and strong. The protective box has a high strength and uses a soft protective material for the inner lining, which serves to cushion, insulate, and prevent moisture from the gas cylinder body 12. The first-size storage compartment 5 can hold a standard small-sized gas cylinder body 12, and the second-size storage compartment can hold a standard large-sized gas cylinder body 12. The tool storage compartment 301 is used to store tools and accessories used for assembling multiple gas cylinders. The gas cylinder protective box can be moved by casters 102 and pull rod 10, which provides space for tools and accessories as well as space for gas cylinder bodies 12 of different sizes. It is fixed by fixing straps 7, which increases the protectiveness and stability of the protective box.

[0028] As a preferred technical solution of this embodiment, a cover plate 3 is rotatably installed on the tool storage partition 301, and a magnetic block 4 is provided on the inner wall of the tool storage partition 301. The cover plate 3 is magnetically connected to the magnetic block 4. The tool storage partition 301 can be closed by the cover plate 3 to prevent the tool accessories from shaking.

[0029] As a preferred technical solution of this embodiment, a load-bearing plate 302 is fixedly connected between the tool storage partition 301 and the two first-specification storage partitions 5; the load-bearing plate 302 can increase the load-bearing capacity of the tool storage partition 301 and prevent the bottom plate of the partition from deforming due to placing excessively heavy objects on the tool storage partition 301.

[0030] As a preferred technical solution in this embodiment, the inside of the cover 1 is provided with a protective layer 11; the protective layer 11 is preferably made of pearl cotton, which can protect the gas cylinder body 12.

[0031] As a preferred technical solution of this embodiment, a handle 9 is fixedly installed on the top of the box body 2, and a pull rod 10 is provided on the side of the box body 2 away from the box cover 1; the protective box can be lifted by the handle 9, and the pull rod 10, together with the universal wheels 102, can drag the box body 2 on the ground.

[0032] Example 2

[0033] This embodiment is implemented based on Embodiment 1 above, with reference to... Figure 3-7The fixing strap 7 and the inner wall of the box 2 and the side wall of the partition are all provided with disassembly and assembly components. The top of the first specification storage partition 5 and the second specification storage partition 6 are both provided with telescopic limiting components 17. The disassembly and assembly components can fix the fixing strap 7 at different positions. In order to ensure that the partition can be smoothly placed into the gas cylinder body 12, the height of the partition will be slightly higher than the gas cylinder body 12. The telescopic limiting components 17 can fill and limit the gap at the top of the gas cylinder body 12 after it is placed in.

[0034] As a preferred technical solution of this embodiment, the disassembly and assembly assembly includes multiple fasteners 14 and nuts 16 fixedly installed on the inner walls of both sides of the first-size storage partition 5 and the second-size storage partition 6. Both ends of the fixing strap 7 are provided with through holes 15. The fixing strap 7 is sleeved on the fasteners 14 through the through holes 15 on both sides and locked with nuts 16. By sleeved on the corresponding fasteners 14 through the through holes 15 at both ends of the fixing strap 7 and then locked with nuts 16, the installation and fixation of the fixing strap 7 can be realized, which facilitates the replacement of the fixing strap 7.

[0035] As a preferred embodiment, the telescopic limiting component 17 includes a fixed cylinder 18 fixedly installed at the top of the first-specification storage partition 5 and the second-specification storage partition 6. The fixed cylinder 18 has a first threaded portion 19, and a first sleeve 20 is fitted onto the fixed cylinder 18, threadedly connected to the first threaded portion 19. The first sleeve 20 has a second threaded portion 21 and a second sleeve 22 is fitted onto it, threadedly connected to the second threaded portion 21. The bottom end of the cylinder is rotatably mounted with an abutment 23, and the bottom end of the abutment 23 is fixedly mounted with a locking claw 24. By rotating the first sleeve 20, the first sleeve 20 can be adjusted downwards, and by rotating the second sleeve 22, the second sleeve 22 can be adjusted downwards. The abutment 23 of the second sleeve 22 can abut against the top of the gas cylinder body 12 to prevent the gas cylinder body 12 from shaking up and down. The locking claw 24 can fix the gas cylinder rotating valve 13 to prevent the gas cylinder rotating valve 13 from spinning, which can increase the safety protection performance of the device.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
