[0002] Fire trucks, also known as fire trucks, are vehicles designed and manufactured to be suitable for firefighters to ride, equipped with various firefighting equipment or fire extinguishing agents, and used by firefighting forces for firefighting, auxiliary firefighting or fire rescue. They are usually double-row vehicles, and fire departments in most countries, including China, will also use them for other emergency rescue purposes. Fire trucks can transport firefighters to the disaster site and provide them with a variety of tools for disaster relief tasks. Fire trucks often travel to disaster sites. In order to prevent fire trucks from being damaged, anti-impact structures are generally set on the sides of fire trucks.

[0003] Traditional side impact protection structures for fire trucks often use guardrails made of metal. Although this method has a simple structure, in actual use, it is easy to cause a large impact on the vehicle body after a collision, which can easily cause the vehicle body to shake violently, and then cause the fire-fighting equipment in the vehicle to shift or be damaged due to the shaking. Therefore, it is necessary to design and modify the side impact protection structure for fire trucks to effectively prevent the phenomenon of poor impact protection. Utility Model Content

[0021] refer to Figures 1 to 3 A handle 13 is fixedly connected to the surface of the movable frame 9.

[0022] As a technical optimization solution of the present invention, the provision of the handle 13 can facilitate the operator to pull the movable frame 9 to both sides.

[0023] refer to Figure 1 , Figure 2 and Figure 4 A bearing is fixedly connected inside the support frame 4, and the bearing is fixedly connected to the sleeve 5.

[0024] As a technical optimization solution of the present invention, the friction between the support frame 4 and the sleeve 5 can be reduced by setting the bearing, thereby facilitating the rotation of the sleeve 5.

[0025] refer to Figure 2 and Figure 4 An elastic band 14 is fixedly connected to the surface of the sleeve 5 , and the elastic band 14 is fixedly connected to the support frame 4 .

[0026] As a technical optimization solution of the utility model, through the setting of the elastic band 14, when the sleeve 5 rotates, the elastic band 14 will be wrapped around the surface of the sleeve 5, thereby stretching the elastic band 14, and utilizing the elasticity of the elastic band 14 itself, thereby exerting a reverse rotation force on the sleeve 5.

[0027] refer to Figures 1 to 3 The front sides of the baffle plate 3 and the movable plate 8 are both fixedly connected with a heat insulation layer 11 .

[0028] As a technical optimization solution of the present invention, the heat exchange rate between the front and back sides of the baffle 3 and the movable plate 8 can be reduced by setting the heat insulation layer 11, thereby preventing the fire truck from being damaged by high temperature.

[0029] refer to Figures 1 to 3 A fireproof layer 12 is fixedly connected to the front side of the heat insulation layer 11 .

[0030] As a technical optimization solution of the present invention, the fireproof layer 12 can be provided to achieve a fireproof effect.

[0031] The working principle and use process of the utility model are as follows: when in use, the mounting plate 1 is mounted on both sides of the fire truck by mounting bolts, so as to facilitate the quick disassembly and assembly of the device. When the fire truck is driving at the fire scene, the operator pulls the handles 13 to both sides, so that the two movable frames 9 move away from each other until the movable frames 9 are separated from the card slots, thereby releasing the lock of the movable plate 8. Then the operator moves the movable plate 8 downward to a suitable position, and then releases the movable frame 9. Under the action of the tension spring 10, the two movable frames 9 move closer to each other until the movable frames 9 are movably connected with the card slots, thereby locking the movable plate 8. The movable plate 8 can prevent objects from hitting the tires of the fire truck and prevent objects from entering the bottom of the vehicle and causing damage to the bottom of the vehicle.

[0032] When an object hits the front of the baffle 3 or the movable plate 8, it will drive the baffle 3 to move to the back side, and then drive the threaded rod 6 to move to the back side. Since the threaded rod 6 is threadedly connected to the sleeve 5, the sleeve 5 rotates during the movement of the threaded rod 6 to the back side, thereby driving the torsion spring 7 to rotate. According to the relationship between the action force and the reaction force, the torsion spring 7 has a reverse rotation force on the sleeve 5 at this time, and then has a force to move the threaded rod 6 to the front side, and then indirectly has a force to move the baffle 3 to the front side, thereby performing the first level of buffering for the baffle 3. When the sleeve 5 rotates, the elastic band 14 will be wrapped around the surface of the sleeve 5, thereby stretching the elastic band 14, and utilizing the elasticity of the elastic band 14 itself, thereby having a reverse rotation force on the sleeve 5. Similarly, there is an indirect force to the front side on the baffle 3, thereby performing the second level of buffering for the baffle 3.
