[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1
[0023] Reference Figure 1-5This utility model is a multi-functional trailer, including a trailer frame 1, a U-shaped plate 2 fixedly connected to the trailer frame 1, and an anti-loosening component, which includes a rotating sleeve 3, the rotating sleeve 3 being rotatably connected to the U-shaped plate 2, a sliding rod 7 being slidably connected inside the rotating sleeve 3, and several anti-loosening blocks 11 being slidably connected to the rotating sleeve 3. Ear plates 10 are fixedly connected to the periphery of the sliding rod 7, and a hinge rod 12 is fixedly connected between the anti-loosening blocks 11 and the ear plates 10. A bracket 13 is fixedly connected to the trailer frame 1, and the anti-loosening blocks 11 and the bracket 13 are interlocked. A gear 4 is fixedly connected to the end of the rotating sleeve 3, and two racks 5 mesh on the gear 4.
[0024] The operation process in this embodiment is as follows: After placing the water hose on the trailer frame 1 and securing the trailer frame 1 to the fire truck, transportation can begin. During transportation, to prevent the water hose from being knocked out of the trailer frame 1, the rotating sleeve 3 is rotated to drive the gear 4 to rotate. Figure 2 As shown, the rotation of gear 4 drives the two racks 5 to move inward, thereby causing the clamping plate 18 to clamp the water hose on the trailer frame 1, preventing the water hose from accidentally falling off due to bumps during transportation.
[0025] In actual use, when encountering bumpy roads, gear 4 may rotate, causing the two racks 5 to move outwards, loosening the clamping of the hose and reducing its fixing effect. Therefore, the anti-loosening block 11 maintains its position during transportation. Figure 5 At the position shown, the anti-loosening block 11 is inserted into the insert 13. Multiple anti-loosening blocks 11 simultaneously limit the rotation sleeve 3, preventing the gear 4 from moving abnormally due to bumps during transportation. This prevents the water hose from becoming loose and falling off the trailer frame 1 during transportation.
[0026] Example 2
[0027] The anti-loosening block 11 is inserted into the insert 13, which can prevent the rotating sleeve 3 from loosening during transportation, but it hinders the clamping of the water hose during loading. For this reason, please refer to Figure 2-4 Based on the first specific embodiment, a circular plate 6 is fixedly connected inside the rotating sleeve 3. The circular plate 6 is slidably engaged with the slide rod 7. A baffle 8 is fixedly connected to the side of the slide rod 7. A spring 9 is fixedly connected between the baffle 8 and the circular plate 6. Two racks 5 are arranged parallel to each other, with the teeth of the two racks 5 facing each other. A pressing block 17 is fixedly connected to the end of the rack 5. A pressing plate 18 is fixedly connected to the bottom surface of the pressing block 17. The pressing plate 18 is slidably engaged with the trailer frame 1. A sliding groove is provided on the trailer frame 1. A slider is fixedly connected to the side of the pressing plate 18. The slider is slidably engaged with the sliding groove. A pull ring 15 is fixedly connected to the end of the slide rod 7. A rotating wheel 16 is fixedly connected to the side of the rotating sleeve 3.
[0028] The operation process of this embodiment is as follows: During the loading stage, after the water hose is placed in the trailer frame 1, the rotating sleeve 3 is rotated and the pull ring 15 is pulled. The pull ring 15 drives the slide rod 7 to move. The slide rod 7 moves, thereby compressing the spring 9 and driving the ear plate 10 to move. Since the ear plate 10 is connected to each anti-loosening block 11 through the hinge rod 12, at this time, as the ear plate 10 moves, each anti-loosening block 11 moves out from the insert frame 13, releasing the restriction on the rotating sleeve 3, so that the rotating sleeve 3 can rotate freely. After loading is completed, the pull ring 15 is released, and the spring 9 can drive each anti-loosening block 11 to re-insert into the insert frame 13 to complete the reset. This avoids the situation where each anti-loosening block 11 is inserted into the insert frame 13 and it is not easy to tighten the water hose, thus speeding up the loading speed and improving the rescue efficiency.
[0029] The sliding groove provided on the trailer frame 1 can improve the stability of the clamping plate 18 during movement and prevent the clamping plate 18 from separating from the trailer frame 1 during bumpy conditions, which would cause the water hose to shift. The rotating sleeve 3 is fixedly connected to the side of the rotating sleeve 3, which makes it more convenient for the user to tighten the water hose on the trailer frame 1.
[0030] Example 3
[0031] When the water hose comes into contact with the clamping plate 18, the coefficient of friction between them is relatively low during transportation due to bumps, and they may still detach. Please refer to [link / reference needed]. Figure 1-3 Based on the first specific embodiment, the insert 13 has a circular hole, and the insert 13 has a number of slots 14 arranged along the circumference of the circular hole. The anti-loosening block 11 is inserted into the slot 14. The anti-loosening block 11 is a rectangular block. The clamping plate 18 has a number of anti-slip strips fixedly connected to one side near the gear 4.
[0032] The operation process of this embodiment is as follows: the rotating sleeve 3 does not contact the round hole. When the pull ring 15 is loosened, each anti-loosening block 11 is inserted into the corresponding slot 14 to complete the locking after tightening. Anti-slip strips are set on the side of the pressure plate 18. The anti-slip strips are made of rubber, which can further improve the tightening effect on the water hose.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
