Description

Technical Field

[0001] This utility model relates to the technical field of dry powder fire extinguishers, specifically a wheeled dry powder fire extinguisher. Background Technology

[0002] Dry powder fire extinguishers are classified into three types according to their mobility: hand-held, backpack, and wheeled. Each of these types has certain disadvantages: hand-held and backpack fire extinguishers contain less dry powder extinguishing agent, making them difficult to handle larger fires, and they also increase the labor intensity of firefighters. Wheeled dry powder fire extinguishers, on the other hand, are stable when moved by the wheeled vehicle, which is supported by the wheels and the firefighter's hands, allowing them to extinguish fires.

[0003] A search revealed a wheeled dry powder fire extinguisher disclosed in Chinese Patent Publication No. CN216295069U. The key technical feature is that by pulling the insert block out from the top of the fixing block and the connecting block, the fixing plate can be rotated, causing two arc-shaped plates to move closer or further apart. When the two arc-shaped plates move closer, they can clamp and fix the fire extinguisher body in conjunction with the placement groove on the rotating plate, allowing the fire extinguisher body to be placed and fixed on the wheeled vehicle. When the two arc-shaped plates move further apart, the fire extinguisher body can be removed from the rotating plate, facilitating the replacement of the fire extinguisher body.

[0004] However, existing technologies cannot quickly support and fix the fixing plate, resulting in instability in the placement of the fixing plate with the clamping plate, and thus the clamping plate cannot stably clamp the fire extinguisher box. In order to solve the problem of the inability to quickly support and fix the fixing plate in the existing technology, this application proposes to rotate the fixing plate around the support block and place it vertically, then move the support plate around the corresponding connecting block, and then pull the pull block to make the corresponding plug slide horizontally along the corresponding support plate. At this time, the spring will be compressed until the plug and the corresponding slot are on the same central axis. At this time, the pull block is released, and the spring will push the corresponding plug into the corresponding slot under the action of its rebound force. Thus, the fixing plate can be quickly supported and fixed through the insertion between the plug and the corresponding slot. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The aforementioned background technology addresses the problem that existing technologies cannot quickly support and fix the fixing plate.

[0006] This utility model discloses a wheeled dry powder fire extinguisher, including a vehicle body. Four connecting blocks are fixedly connected to the upper surface of the vehicle body. A support plate is rotatably connected to the outer surface of each connecting block. A rod is slidably connected to the inner wall of each support plate. A spring is sleeved on the outer surface of each rod. Two support blocks are slidably connected to the inner wall of the vehicle body. A fixing plate is rotatably connected to the upper surface of each support block. A slot is opened on the outer surface of each fixing plate. The outer surface of each rod is inserted into the corresponding slot. A pull block is fixedly connected to the end of each rod away from the corresponding fixing plate.

[0007] Furthermore, the vehicle body is equipped with two first screws inside, and the outer surface of each first screw is rotatably connected to the vehicle body.

[0008] Furthermore, the outer surface of each first screw is threadedly connected to the corresponding support block, and a second wheel is fixedly connected to the end of each first screw away from the vehicle body.

[0009] Furthermore, a baffle is fixedly connected to the upper surface of each support block, and the outer surface of each baffle is engaged with the corresponding fixing plate.

[0010] Furthermore, a mounting groove is provided on the upper surface of the vehicle body, and a fire extinguisher box is inserted into the inner wall of the mounting groove.

[0011] Furthermore, each of the fixed plates has a connecting rod slidably connected to its inner wall, and each connecting rod has a clamping plate fixedly connected to one end near the fire extinguishing box.

[0012] Furthermore, each of the two clamping plates is rotatably connected to a second screw at one end away from the fire extinguishing box, and a first rotating wheel is fixedly connected to the end of each second screw away from the fire extinguishing box. The outer surface of each second screw is threadedly connected to the corresponding fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model comprises a vehicle body, a support block, a connecting block, a support plate, a plug rod, a spring, a support block, a fixing plate, a slot, and a pull block. By rotating the fixing plate to make it rotate around the support block and place it vertically, and then moving the support plate to rotate around the corresponding connecting block, and then pulling the pull block, the corresponding plug rod is moved to slide horizontally along the corresponding support plate. At this time, the spring is compressed until the plug rod and the corresponding slot are on the same central axis. At this time, the pull block is released, and the spring will push the corresponding plug rod into the corresponding slot under its rebound force. Thus, the device can quickly support and fix the fixing plate through the plug rod and the corresponding slot.

[0014] 2. This utility model, by setting up components such as a first rotating wheel, a second screw, a connecting rod, a clamping plate, and a fixing plate, achieves the effect of tightly clamping the fire extinguisher box by rotating the first rotating wheel, which in turn drives the corresponding second screw to rotate. The rotation of the second screw pushes the corresponding clamping plate to move horizontally toward the fire extinguisher box. The connecting rod prevents the clamping plate from rotating with the second screw, thus achieving the effect of the device being able to tightly clamp the fire extinguisher box by the rotation of the second screw pushing the clamping plate.

[0017] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0018] Please see Figure 1 , Figure 3This utility model discloses a wheeled dry powder fire extinguisher, including a vehicle body 1. Four connecting blocks 8 are fixedly connected to the upper surface of the vehicle body 1. Each connecting block 8 has a support plate 9 rotatably connected to its outer surface. Each support plate 9 can rotate around the corresponding connecting block 8. Each support plate 9 has a slidably connected insert rod 11 to its inner wall. Each insert rod 11 can slide horizontally along the corresponding support plate 9. Each insert rod 11 has a spring 12 sleeved on its outer surface. By pulling the insert rod 11, the insert rod 11 will slide horizontally along the corresponding support plate 9. Then the spring 12 will be compressed. Without external force, the spring 12 will push the corresponding insert rod 11 to reset under its rebound force.

[0019] In a preferred embodiment, two support blocks 5 are slidably connected to the inner wall of the vehicle body 1. Each support block 5 has a fixed plate 6 rotatably connected to its upper surface. Each support block 5 can slide horizontally along the vehicle body 1, and each fixed plate 6 can rotate around the corresponding support block 5. Each fixed plate 6 has a slot 7 on its outer surface. The slots 7 are located on the left and right sides of the corresponding fixed plate 6. The outer surface of each insert rod 11 is inserted into the corresponding slot 7. A pull block 13 is fixedly connected to the end of each insert rod 11 away from the corresponding fixed plate 6. Specifically, by rotating the fixed plate 6 so that it is perpendicular to the support block 5, and then rotating the support plate 9 so that the insert rod 11 and the corresponding slot 7 are on the same central axis, and then by resetting the insert rod 11 so that the insert rod 11 is inserted into the corresponding slot 7, the fixed plate 6 can be quickly supported and fixed.

[0020] In this embodiment, the vehicle body 1 is provided with two first screws 4 inside, and the outer surface of each first screw 4 is rotatably connected to the vehicle body 1. Specifically, the first screw 4 can rotate inside the vehicle body 1, and the two first screws 4 are on the same central axis.

[0021] like Figure 2 As shown, the outer surface of each first screw 4 is threadedly connected to the corresponding support block 5. The end of each first screw 4 away from the vehicle body 1 is fixedly connected to a second rotating wheel 18. Specifically, by rotating the second rotating wheel 18, the second rotating wheel 18 will drive the corresponding first screw 4 to rotate. The rotation of the first screw 4 will drive the corresponding support block 5 to slide horizontally along the vehicle body 1.

[0022] Looking back Figure 1 , Figure 2 , Figure 4 Each support block 5 has a baffle 10 fixedly connected to its upper surface. The outer surface of each baffle 10 is engaged with the corresponding fixed plate 6. Specifically, the baffle 10 limits the rotation of the fixed plate 6, so that the rotation of the fixed plate 6 will be vertical.

[0023] In this embodiment, a mounting groove 2 is provided on the upper surface of the vehicle body 1, and a fire extinguishing box 3 is inserted into the inner wall of the mounting groove 2. Specifically, the mounting groove 2 is designed so that the fire extinguishing box 3 can be placed inside the mounting groove 2.

[0024] In this embodiment, a connecting rod 15 is slidably connected to the inner wall of each fixing plate 6. The connecting rod 15 is perpendicular to the corresponding fixing plate 6. A clamping plate 16 is fixedly connected to one end of each connecting rod 15 near the fire extinguishing box 3. Specifically, the horizontal movement of the clamping plate 16 causes the clamping plate 16 to quickly clamp the fire extinguishing box 3. During this process, the connecting rod 15 slides horizontally along the corresponding fixing plate 6.

[0025] In a preferred embodiment, each of the two clamping plates 16 is rotatably connected to a second screw 14 at one end away from each other. Each second screw 14 is parallel to the corresponding connecting rod 15. Each second screw 14 is fixedly connected to a first rotating wheel 17 at the end away from the fire extinguishing box 3. By rotating the first rotating wheel 17, the first rotating wheel 17 will drive the corresponding second screw 14 to rotate. At this time, the rotation of the second screw 14 will move horizontally along the corresponding fixed plate 6, thereby pushing the corresponding clamping plate 16 to tightly clamp the fire extinguishing box 3. The outer surface of each second screw 14 is threadedly connected to the corresponding fixed plate 6.

[0026] The implementation principle is as follows: First, place the fire extinguisher box 3 in the mounting slot 2. Then, rotate the second rotating wheel 18, which will drive the corresponding first screw 4 to rotate. The rotation of the first screw 4 will drive the corresponding support block 5 to slide horizontally along the vehicle body 1. Then, rotate the fixing plate 6 to rotate around the corresponding support block 5. The fixing plate 6 can be limited by the baffle 10. At this time, by moving the support plate 9, each support plate 9 can rotate around the corresponding connecting block 8. Then, pull the pull block 13, which will drive the corresponding support block 8 to rotate around the vehicle body 1. The corresponding insertion rod 11 slides horizontally along the corresponding support plate 9. At this time, the spring 12 will be compressed. By rotating the support plate 9 and making the slot 7 and the corresponding insertion rod 11 on the same central axis, and then releasing the pull block 13, the spring 12 will push the corresponding insertion rod 11 to reset and insert into the corresponding slot 7 under its rebound force, thereby quickly fixing the fixing plate 6. Then, the first rotating wheel 17 is rotated, which will drive the corresponding second screw 14 to rotate, thereby pushing the corresponding clamping plate 16 to tightly clamp the fire extinguishing box 3.
