[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0021] Please see Figure 1-5 This utility model provides a novel nitrogen cylinder fixing device, including a base 1, a middle seat 2, and a top cover 3. Multiple middle seats 2 are provided and are connected in a stacked manner between the base 1 and the top cover 3. The gap space for clamping the cylinder is formed between the base 1 and the middle seat 2, between each adjacent middle seat 2, and between the middle seat 2 and the top cover 3. Connecting parts 4 are provided at the four corners of the upper side of the base 1, the upper and lower sides of the middle seat 2, and the lower side of the top cover 3. Each adjacent upper and lower connecting part 4 is connected by a snap-fit ​​component.

[0022] Specifically, the bottom of the base 1 is provided with fixing holes for bolt connection and fixation to the vehicle's cabin floor. The entire device is detachably installed on the equipment box floor using bolts, facilitating modification and disassembly. Multiple middle seats 2 are provided, the number determined according to the required number of nitrogen cylinders to be fixed, to accommodate multiple rows of nitrogen cylinders. Gap spaces for laterally accommodating nitrogen cylinders are formed between the bottom middle seat 2 and the base 1, between adjacent middle seats 2, and between the top cover 3 and the top middle seat 2. Multiple corresponding arc plates conforming to the sidewall contours of the nitrogen cylinders are provided on the upper and lower sides of each gap space, thereby limiting and fixing multiple nitrogen cylinders within the gap space. Damping pads are provided on the inner walls of each gap space for vibration reduction, buffering, and eliminating gaps caused by deformation. The gap space is figure-eight shaped and can hold a pair of cylinders. In this embodiment, the base 1 is a rectangular frame structure, consisting of two base plates, an inner base plate connected by small ribs, and an outer base plate. An external frame with an upward-facing opening is formed, with the ends connected by bottom tie rods. The middle seat 2 is a rectangular frame structure, consisting of two middle station plates that are equidistantly spaced by small ribs, an inner middle plate, and an outer middle plate to form an upward-facing external frame, with the ends connected by middle tie rods and reinforced by ribs. The top cover 3 is a rectangular frame structure, consisting of two upper station plates that are equidistantly spaced by small ribs, a top cover plate, and upper ribs to form a downward-facing external frame, with the ends connected by middle tie rods and reinforced by ribs. In use, the bottommost nitrogen cylinder is fixed in place by the gap between the base 1 and the middle seat 2. Similarly, the second and third rows of nitrogen cylinders are fixed in place by the gap between the middle seats 2. The topmost row of nitrogen cylinders is fixed in place by the gap between the middle seat 2 and the top cover 3. This achieves the fixed installation of multiple layers and two columns of nitrogen cylinders. The number of layers of nitrogen cylinders can be adjusted by adjusting the number of layers in the middle seat 2. The middle seat 2 is preferably 1-5 layers. The connecting part 4 is preferably in the shape of a square. The four corresponding connecting parts 4 between the base 1 and the middle seat 2, between adjacent middle seats 2, or between the middle seat 2 and the top cover 3 have achieved a fixed connection between the upper and lower components. When disassembling, the four corner connecting parts can be disconnected. In actual use, when the connecting parts are tightened, the gap space formed between each base 1 and the middle seat 2, between adjacent middle seats 2, and between the middle seat 2 and the top cover 3 can firmly clamp the bottle. When the connecting parts are disconnected, the bottle can be easily removed layer by layer without affecting the fixation of the next layer of bottle.

[0023] Compared with the prior art, the novel nitrogen cylinder fixing device proposed in this utility model embodiment, by setting a snap-fit ​​component, makes the frame structure composed of base 1, middle seat 2 and top cover 3 easy to disassemble. When the snap-fit ​​component is tightened, the gap space formed between each base 1 and middle seat 2, between adjacent middle seats 2, and between middle seat 2 and top cover 3 can firmly clamp the cylinder. When the snap-fit ​​component is disconnected, the cylinder can be easily removed layer by layer without affecting the fixing of the next layer of cylinder. It can meet the installation, disassembly and replacement of nitrogen cylinder groups for emergency rescue and repair tasks of fire trucks after fire truck modification. It has the characteristics of modularity, high versatility, speed and convenience, and is easy to manufacture, low cost and convenient to install.

[0024] As a preferred technical solution of this embodiment, the snap-fit ​​assembly includes a pin 5 provided on the downward-facing connecting part 4 and a slot 6 provided on the upward-facing connecting part 4. The side wall of the pin 5 is provided with a resiliently movable limiting member 7, and the side wall of the slot 6 is provided with a limiting hole 8 that matches the limiting member 7. Specifically, the base 1 is provided with only one set of upward-facing connecting parts 4, the middle seat 2 is provided with two sets of connecting parts 4 that are respectively upward-facing or downward-facing, and the top cover 3 is provided with only one set of downward-facing connecting parts 4. On the base 1, the connecting part 4 is provided with a slot 6; on the middle seat 2, the downward-facing connecting part 4 is provided with a pin 5, and the upward-facing connecting part 4 is provided with a slot 6; on the top cover 3, the connecting part 4 is provided with a pin 5; the end of the limiting member 7 is provided with a shovel-shaped or ball-shaped design to facilitate snap-fitting or disassembly; the limiting member 7 is embedded in the corresponding limiting hole 8, that is, it restricts the two vertically mating connecting parts 4 from moving away from each other.

[0025] As a preferred technical solution in this embodiment, the lower end of the pin 5 is provided with a retraction groove 9, and an elastic element 10 is provided in the retraction groove 9. One end of the limiting element 7 is slidably disposed in the retraction groove 9 and connected to the elastic element 10. Specifically, one side of the retraction groove 9 is open for the limiting element 7 to extend. The elastic element 10 is preferably a spring. The elastic element 10 maintains elasticity to push the limiting element 7, so that the limiting element 7 remains extended. When the limiting element 7 corresponds to the limiting hole 8, the limiting element 7 is held embedded in the limiting hole 8 under this elastic force. When disassembling, by pressing the extended end of the limiting element 7 with external force, the limiting element 7 can compress the elastic element 10 to retract, thereby disengaging from the limiting hole 8, thus facilitating the disassembly between the two connected connecting parts 4.

[0026] As a preferred technical solution in this embodiment, the pin 5 is movably mounted on the connecting part 4. The connecting part 4 is provided with an adjustment component for adjusting the height of the pin 5. Specifically, the downward-facing connecting part 4 is provided with a through groove 11 that matches the pin 5, and the pin 5 is movably mounted through the through groove 11. In actual use, the nitrogen cylinder is clamped and fixed in the gap space, requiring the removal of the top cover 3 or further removal of the middle seat 2 to remove the nitrogen cylinder for use, which is time-consuming. Moreover, after removal, the top cover 3 and the middle seat 2 require additional space for carrying. This embodiment addresses this issue by eliminating the clamping of the nitrogen cylinder without removing the top cover 3 or the middle seat 2. The adjustment component can adjust the height of the pin 5, thereby adjusting the height of the limiting member 7 relative to the limiting hole 8. When the height of the pin 5 decreases, the maximum height of the gap space increases, thus eliminating the clamping of the nitrogen cylinder. The nitrogen cylinder can be pulled out of the gap space, eliminating the requirement to completely remove the top cover 3 or the middle seat 2.

[0027] As a preferred embodiment, the adjustment assembly includes a slider 12 movably disposed within the connecting portion 4, a guide groove 13 on the slider 12, a sliding pin 14 fixedly disposed at the upper end of the pin 5 and movably connected to the guide groove 13, and an adjusting bolt 15 rotatably disposed on the connecting portion 4. The adjusting bolt 15 is threadedly connected to the slider 12. Specifically, the slider 12 slides horizontally, the guide groove 13 is inclined, and the sliding pin 14 can slide relative to the guide groove 13. The adjusting bolt 15 controls the slider 12 to slide, thereby changing the position of the sliding pin 14 within the guide groove 13, and thus adjusting the height of the pin 5 relative to the connecting portion 4. In actual use, the adjusting bolt 15 can be rotated to make the slider 12 slide, and the slider 12 drives the guide groove 13 on it to move relative to the sliding pin 14. This reduces the relative height of the pin 5 on the connecting portion 4, thereby achieving the maximum height of the expanded gap space, eliminating the need to clamp the nitrogen cylinder, and eliminating the requirement to completely disassemble the top cover 3 or the middle seat 2.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
