Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment fixing technology, and in particular to a fire extinguisher anti-sway fixing bracket for fire dispatch vehicles. Background Technology

[0002] During fire emergency responses, vehicle-mounted fire extinguishers need to be securely fixed to cope with complex road conditions. The practicality of the fixing device directly affects the efficiency of the response and the safety of use. Currently, many vehicle-mounted fire extinguisher fixing devices on the market have insufficient installation compatibility. Some devices require drilling to fix them to the vehicle, which is not only cumbersome but also can damage the vehicle structure and cannot flexibly adapt to the installation space of different vehicle models. Other devices have a fixed structure, making it difficult to adjust the angle according to the actual installation position, which can cause the fire extinguisher to interfere with vehicle parts after placement, affecting the normal operation of the vehicle.

[0003] The anti-sway performance and protective effect of existing fixing devices also need to be improved. When firefighters respond to an emergency, vehicles frequently accelerate, brake, and experience bumps. Traditional fixing devices often fail to hold the fire extinguisher securely, causing it to shake, shift, or even fall off, posing a safety hazard. At the same time, most devices lack effective cushioning and protection designs, and hard-contact fixing can easily cause wear and tear on the fire extinguisher bottle or damage to the vehicle's interior. Furthermore, some devices are complex to operate, making it difficult to quickly retrieve the fire extinguisher in an emergency, thus delaying rescue opportunities.

[0004] As a company specializing in the production of fire-fighting equipment, we urgently need to develop a fixing device that is structurally sound, angle-adjustable, stable, and easy to operate, addressing the shortcomings of existing technologies and the actual needs of fire emergency response. This device must balance installation flexibility and safety, adapting to the installation space of different vehicle models while effectively blocking the extinguisher's movement path through a reliable fixing structure. It must also simplify the operation process, ensuring rapid access to the extinguisher in emergencies and meeting the high standards of the fire protection industry for vehicle-mounted fire extinguisher fixing devices. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fire extinguisher anti-sway fixing bracket for fire trucks, which solves the technical problems of existing vehicle fire extinguisher fixing devices requiring drilling for installation, which damages the vehicle structure; fixed angles that cannot adapt to different vehicle models and installation spaces; easy shaking and falling off in complex road conditions; hard contact causing wear and tear on the bottle body and vehicle; and cumbersome operation that affects emergency access.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The fire extinguisher anti-sway fixing bracket for fire dispatch vehicles includes a support plate, ear plate, uprights, crossbar one, anti-detachment clamp, vertical plate, crossbar two, clamp arm, nut, knob, rotating shaft, positioning hole, positioning pin and limit block.

[0027] This application provides a fire extinguisher anti-sway fixing bracket for fire trucks, which effectively solves the technical problems of existing vehicle-mounted fire extinguisher fixing devices, such as the need for drilling to install, which damages the vehicle structure; the fixed angle cannot be adapted to the installation space of different vehicle models; the extinguishers are prone to shaking and falling off in complex road conditions; hard contact causes wear and tear on the bottle body and vehicle; and the operation is cumbersome, affecting emergency access.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing vehicle-mounted fire extinguisher fixing devices, such as requiring drilling for installation which damages the vehicle structure, the fixed angle which cannot adapt to the installation space of different vehicle models, the ease with which they shake and fall off in complex road conditions, hard contact causing wear and tear on the bottle body and vehicle, and cumbersome operation which affects emergency access. The overall idea is as follows:

[0030] Ear plates 2 and support plate 1 are fixed: two ear plates 2 are symmetrically installed in the preset positions of support plate 1 to ensure that ear plates 2 and support plate 1 fit tightly; the rotating shaft 12 is inserted through the shaft hole at the bottom of the two uprights 3, and then the two ends of the rotating shaft 12 are connected to the two ear plates 2 respectively, so that the uprights 3 can rotate freely around the rotating shaft 12; the bolts on the side of the ear plate 2 away from the rotating shaft 12 are inserted through the reserved hole of the ear plate 2 so that the end face of the bolt fits with the surface of the rotating shaft 12.

[0031] Angle adjustment of support plate 1: According to the spatial angle requirements of the vehicle installation position, manually rotate support plate 1 to drive the upright 3 to rotate around the rotation axis 12. Observe the five circumferential positioning holes 13 on the ear plate 2. When the support plate 1 rotates to the target angle, stop rotating to ensure that the second positioning hole 16 on the upright 3 is aligned with one of the positioning holes 13 on the ear plate 2.

[0032] Angle locking and fixing: Insert the positioning pin 14 into the aligned positioning hole 13 and positioning hole 16, ensuring that the positioning pin 14 completely passes through the two holes, thereby fixing the upright 3 and the ear plate 2 relative to each other; then tighten the bolts on the ear plate 2 to press the bolts against the rotating shaft 12, further enhancing the stability of the rotating shaft 12 and preventing the positioning pin 14 from falling off due to force when the vehicle is bumpy, thus completing the angle locking.

[0033] Frame structure reinforcement inspection: Confirm the fixed connection status of horizontal bar 4 and vertical bar 3, and ensure that horizontal bar 4 and horizontal bar 8 are arranged in parallel; check the corresponding assembly position of horizontal bar 8 and anti-detachment clamp 5, and ensure that the anti-detachment clamp 5 is firmly installed in the middle of the two vertical bars 3 without loosening or displacement, and that the overall frame structure does not shake.

[0034] Working principle:

[0035] Fire extinguisher placement and pre-positioning: Place the fire extinguisher vertically on the support plate 1, adjust the position of the cylinder so that the arc-shaped anti-detachment clamp 5 in the middle of the upright 3 fits against the side of the fire extinguisher cylinder, forming a preliminary lateral positioning; the support plate 1 has a groove 7, and a central shaft is integrally formed in the groove 7. The bottom of the vertical plate 6 is rotatably connected to the central shaft, and the angle of the vertical plate 6 can be adjusted by the central shaft to adapt to the direction of the fire extinguisher cylinder; ensure that the bottom of the fire extinguisher is completely in contact with the support plate 1, without being suspended or tilted, that the first horizontal bar 4 and the second horizontal bar 8 do not interfere with the cylinder, and that the handle on the top of the cylinder can be operated normally.

[0036] Clamping arm 9 clamping drive: Manually rotate the knob 11 on the top clamping arm 9 of the vertical plate 6. Since the knob 11 is fixedly connected to the nut 10, when the knob 11 rotates, it drives the nut 10 to move axially along the clamping arm 9. Using the principle of thread transmission, the nut 10 converts the rotational force into the radial clamping force of the clamping arm 9, driving the two clamping arms 9 to move inward synchronously until the inner side of the clamping arm 9 is tightly attached to the fire extinguisher bottle body. When the knob 11 can no longer be tightened, stop the operation. At this time, the limiting block 15 at the other end of the nut 10 has abutted against the end face of the clamping arm 9, avoiding excessive clamping and damage to the bottle body. During the process, the angle of the vertical plate 6 can be finely adjusted by the central shaft in the groove 7 to ensure that the clamping arm 9 is more tightly attached to the bottle body.

[0037] Multi-point fixation confirmation: Check the overall status of the support plate 1 bottom bearing + anti-detachment clamp 5 lateral limit + clamp arm 9 precise clamping + groove 7 and central axis coordinated limit. The fire extinguisher has no vertical bounce space, no horizontal deviation, and no front and back sliding. Gently push the fire extinguisher body to confirm that the fixing frame is not deformed, all connecting parts are not loose, the positioning pin 14 has not come out of the positioning hole 13, and the bolts show no signs of loosening. At the same time, check the connection status of the central axis and the vertical plate 6 in the groove 7 to ensure that there is no looseness.

[0038] Pre-dispatch quick inspection: Before each fire dispatch, focus on checking three items: whether the positioning pin 14 is fully inserted into the positioning hole 13 and positioning hole 16 and has not fallen off; whether the knob 11 is tight, the clamping arm 9 is not loose, and whether the connection between the central shaft in the groove 7 and the vertical plate 6 is secure; and whether the anti-detachment clamp 5 is in close contact with the bottle body and the frame structure is not deformed, to ensure the stability of the device under complex road conditions.

[0039] Regular maintenance: Perform a comprehensive maintenance on the device once a month. Disassemble the positioning pin 14, check the wear of positioning holes 13 and 16, and clean the dust or debris in the holes; rotate the knob 11 to check the smoothness of the thread transmission between the nut 10 and the clamping arm 9, and apply a small amount of grease if necessary; check the connection status of the bolts and rotating shaft 12, tighten any loose parts, and clean the dust and impurities in the groove 7; check the wear of the central shaft to ensure that the vertical plate 6 rotates smoothly; check whether the arc structure of the anti-detachment clamp 5 is deformed and ensure its fit with the bottle body.

[0040] Fire extinguisher disassembly: When the fire extinguisher needs to be retrieved, rotate the knob 11 in the opposite direction to move the nut 10 in the opposite direction along the axial direction of the clamping arm 9, and the clamping arm 9 will loosen the clamping force on the fire extinguisher; adjust the angle of the vertical plate 6 through the central shaft in the groove 7 to reserve space for the fire extinguisher to be removed; grasp the top handle of the fire extinguisher and lift it upward to make the bottle body separate from the anti-detachment clamp 5 and the support plate 1, and the retrieval is completed.

[0041] Angle Adjustment and Storage When Not in Use: If the installation angle needs to be changed, first remove the positioning pin 14 and loosen the bolts on the ear plate 2; rotate the support plate 1 to the new target angle so that the positioning hole 13 and the positioning hole 16 are aligned, reinsert the positioning pin 14, tighten the bolts, and at the same time adjust the angle of the vertical plate 6 through the central shaft in the groove 7 to ensure that the whole is adapted to the new installation position; when the device is not in use, the positioning pin 14 and the bolts on the ear plate 2 can be loosened, the angle of the support plate 1 can be adjusted by rotating the shaft 12, and then the vertical plate 6 can be rotated to a parallel state with the support plate 1 by using the central shaft in the groove 7, so as to achieve the folding and storage of the support plate 1 and the vertical plate 6, reducing space occupation.

[0042] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
