Description

Technical Field

[0001] This utility model relates to the technical field of carbon dioxide fire extinguishers, specifically a carbon dioxide fire extinguisher with protective function. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool. It contains chemicals used to extinguish fires. Fire extinguishers are common fire-fighting equipment, stored in public places or areas where fires may occur. Different types of fire extinguishers contain different components and are designed for different types of fires. Care must be taken when using them to avoid adverse effects and potential dangers.

[0003] A search revealed a Chinese patent with publication number CN220676592U, which discloses a carbon dioxide fire extinguisher with protective function. The key technical point is that this protective carbon dioxide fire extinguisher, through the installation of a protective mechanism, can protect the fire extinguisher during later use, preventing deformation from impacts. When the fire extinguisher is impacted, the impact force causes the connecting rod to move outward, which in turn causes the movable column to rotate within the slot. Simultaneously, the rotating column rotates at one end of the limiting plate, stretching the spring. The spring then resets, causing the connecting rod to reset, which in turn resets the fire extinguisher's casing, thus protecting the casing.

[0004] However, in existing technologies, the protective mechanisms used to protect fire extinguishers leave part of the extinguisher casing exposed, making it susceptible to damage from impacts with sharp objects. This application addresses the limitation of quick assembly and disassembly of the protective plates in existing technologies by cross-connecting two protective plates and inserting them into a first connecting rod. The plates are then rotated to bring them into contact, allowing the connecting frame to slide along the two protective plates vertically into two grooves. During this process, the insert rod is pulled to slide horizontally along the connecting frame, compressing the second spring until the insert rod and slot are aligned on the same central axis. Releasing the insert rod allows the second spring to push it into the slot under its rebound force, thus enabling quick assembly and disassembly of the fully enclosed protective frame. Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The aforementioned background technology addresses the problem that existing technologies cannot quickly assemble or disassemble protective panels.

[0006] This utility model discloses a carbon dioxide fire extinguisher with protective function, including a base. The upper surface of the base has an installation groove. A first connecting rod is fixedly connected to the upper surface of the base. Two protective plates are rotatably connected to the outer surface of the first connecting rod. The outer surface of each protective plate is slidably connected to the other protective plate. Each outer surface of the protective plate has a slot and a sliding groove. A connecting frame is provided above the base. The inner wall of the connecting frame is slidably connected to the two sliding grooves. An insert rod is slidably connected to the inner wall of the connecting frame. A second spring is sleeved on the outer surface of the insert rod. The outer surface of the insert rod is inserted into both slots.

[0007] Furthermore, one end of the second spring near the slot is fixedly connected to the insertion rod, and the other end is fixedly connected to the connecting bracket.

[0008] Furthermore, a fire extinguisher body is provided above the base, and the outer surface of the fire extinguisher body is inserted into the mounting groove.

[0009] Furthermore, a pressure gauge is fixedly installed on the outer surface of the fire extinguisher body, and a handle is fixedly installed on the outer surface of the fire extinguisher body.

[0010] Furthermore, the output end of the fire extinguisher body is fixedly connected to a connecting pipe, and a connector is fixedly installed at the end of the connecting pipe away from the fire extinguisher body.

[0011] Furthermore, each of the protective plates has a plurality of second connecting rods slidably connected to its inner wall. Each second connecting rod has a baffle fixedly connected to one end away from the fire extinguisher body, and a clamping plate fixedly connected to the other end.

[0012] Furthermore, a first spring is sleeved on the outer surface of each of the second connecting rods, and one end of each first spring near the fire extinguisher body is fixedly connected to the corresponding clamping plate, and the other end is fixedly connected to the corresponding protective plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a base, mounting groove, first connecting rod, protective plate, sliding groove, slot, connecting frame, second spring, and insert rod, etc., connects two protective plates crosswise and inserts them into the first connecting rod. Then, the two protective plates are rotated to make them contact each other. At this time, the connecting frame slides in along the two protective plates. The connecting frame will slide vertically along the two sliding grooves. During this process, the insert rod needs to be pulled to make it slide horizontally along the connecting frame. Then, the second spring will be compressed until the insert rod and the slot are on the same central axis. At this time, the insert rod is released, and the second spring will push the insert rod into the slot under the action of its rebound force. Thus, the device can quickly assemble and disassemble the protective plate by installing the connecting frame.

[0014] 2. This utility model, by setting up components such as a clamping plate, a baffle, a first spring, a second connecting rod, and a fire extinguisher body, installs two protective plates. During this process, the clamping plate will contact and compress the fire extinguisher body, and then the second connecting rod will slide horizontally along the corresponding protective plate. At this time, the first spring will be compressed. At this time, the fire extinguisher body of different sizes can be clamped according to the different degrees of compression of the first spring, thereby achieving the effect of quickly clamping fire extinguisher bodies of different sizes through the setting of the first spring.

[0018] Please see Figure 1 , Figure 2 , Figure 3This utility model discloses a carbon dioxide fire extinguisher with protective function, including a base 1. The upper surface of the base 1 has an installation groove 2. A first connecting rod 3 is fixedly connected to the upper surface of the base 1. The first connecting rod 3 is perpendicular to the base 1. Two protective plates 4 are rotatably connected to the outer surface of the first connecting rod 3. The outer surface of each protective plate 4 is slidably connected to the other protective plate 4. By inserting the two protective plates 4, the slots in the two protective plates 4 will be on the same central axis. Then, the two protective plates 4 are inserted along the first connecting rod 3. At this time, both protective plates 4 can rotate around the first connecting rod 3.

[0019] In a preferred embodiment, each protective plate 4 has a slot 18 on its outer surface and a groove 9 on its outer surface. A connecting frame 15 is provided above the base 1. The inner wall of the connecting frame 15 is slidably connected to the two grooves 9. By pressing the two protective plates 4 together, the connecting frame 15 is slid vertically into the two protective plates 4. At this time, the connecting frame 15 will slide vertically into the two grooves 9, thereby fixing the two protective plates 4 through the connecting frame 15. A plug rod 16 is slidably connected to the inner wall of the connecting frame 15. A second spring 17 is sleeved on the outer surface of the plug rod 16. The outer surface of the plug rod 16 is inserted into the two slots 18. Specifically, during the installation of the connecting frame 15, the plug rod 16 needs to be pulled first. The plug rod 16 will slide horizontally along the connecting frame 15, and then the second spring 17 will be compressed.

[0020] In this embodiment, one end of the second spring 17 near the slot 18 is fixedly connected to the insertion rod 16, and the other end is fixedly connected to the connecting bracket 15. Specifically, during the installation of the connecting bracket 15, the insertion rod 16 is released until it is on the same central axis as the two slots 18. The second spring 17 will push the insertion rod 16 into the slot 18 under its rebound force, thereby quickly fixing the two protective plates 4.

[0021] Looking back Figure 2 The base 1 has a fire extinguisher body 10 on top. The outer surface of the fire extinguisher body 10 is inserted into the mounting groove 2. Specifically, by placing the fire extinguisher body 10 in the mounting groove 2, the fire extinguisher body 10 can be placed on the base 1.

[0022] In this embodiment, a pressure gauge 11 is fixedly installed on the outer surface of the fire extinguisher body 10. The pressure gauge 11 will digitally display the carbon dioxide concentration inside the fire extinguisher body 10. A handle 12 is fixedly installed on the outer surface of the fire extinguisher body 10. Specifically, the handle 12 includes a safety pin, a lifting handle, and a pull handle.

[0023] In this embodiment, the output end of the fire extinguisher body 10 is fixedly connected to a connecting pipe 13, and a connector 14 is fixedly installed at the end of the connecting pipe 13 away from the fire extinguisher body 10. Specifically, the carbon dioxide inside the fire extinguisher body 10 can be released through the connection pipe 13 and the connector 14.

[0024] like Figure 2 , Figure 4 As shown, each protective plate 4 has several second connecting rods 6 slidably connected to its inner wall. Each second connecting rod 6 can slide horizontally along the corresponding protective plate 4. Each second connecting rod 6 has a baffle 5 fixedly connected to one end away from the fire extinguisher body 10, and a clamping plate 7 fixedly connected to the other end. Specifically, the second connecting rod 6 is connected to the corresponding baffle 5 and clamping plate 7. At this time, the fire extinguisher body 10 can be clamped by the clamping plate 7. During this process, the fire extinguisher body 10 of different sizes will drive the corresponding second connecting rod 6 to slide horizontally along the corresponding protective plate 4 through the clamping plate 7.

[0025] In this embodiment, a first spring 8 is sleeved on the outer surface of each second connecting rod 6. One end of each first spring 8 near the fire extinguisher body 10 is fixedly connected to the corresponding clamping plate 7, and the other end is fixedly connected to the corresponding protective plate 4. Specifically, the first spring 8 is compressed to different degrees during the clamping process of the clamping plate 7 clamping fire extinguisher bodies 10 of different sizes, and then the clamping plate 7 squeezes and fixes the fire extinguisher body 10.

[0026] The implementation principle is as follows: First, the two protective plates 4 are cross-connected and inserted along the first connecting rod 3. At this time, both protective plates 4 can rotate around the first connecting rod 3. Then, the fire extinguisher body 10 is placed in the mounting groove 2 on the base 1. Then, the protective plates 4 are rotated to close the two. During this process, the clamping plate 7 will clamp the fire extinguisher body 10 of different sizes, and the first spring 8 will be compressed to different degrees. Then, the connecting frame 15 slides vertically along the two protective plates 4. During this process, the insertion rod 16 is first pulled to slide horizontally along the connecting frame 15. Then, the connecting frame 15 will slide vertically along the two sliding grooves 9 until the insertion rod 16 and the two slots 18 are on the same central axis. At this time, under the action of the rebound force of the second spring 17, the insertion rod 16 will be pushed into the slot 18, so that the two protective plates 4 can be quickly disassembled and assembled.
