[0002] A gas cylinder fixing bracket is a frame used for handling, fixing, supporting and protecting high-pressure gas cylinders. Gas cylinders are used in laboratories or industries to store high-pressure, flammable and explosive hazardous gases, such as nitrogen, hydrogen and oxygen. In the storage of high-pressure gas cylinders, it is required that the cylinders be placed vertically and fixed. Therefore, gas cylinder fixing devices are needed in industrial production workshops to keep them upright.

[0003] The existing utility model with authorization announcement number CN205405618U discloses a gas cylinder fixing bracket for nuclear power plants, including a frame and a base plate fixedly connected to the frame. The frame has a cavity for accommodating the gas cylinder, the base plate is used to support the bottom of the gas cylinder, and an openable door is provided on the front side of the cavity. Both the inner side wall of the door and the inner side wall of the rear side of the cavity are provided with buffer pads to fix the gas cylinder by closing the door.

[0004] The above technical solution, which uses a buffer pad to clamp and fix the gas cylinder, can effectively prevent the gas cylinder from shaking or misaligning during storage or use. It also has shock resistance, can withstand severe accidents in nuclear power plants, and effectively prevents movement during violent shaking. Furthermore, it features a compact structure, is easy to install, is suitable for various sizes of gas cylinders, and has strong versatility. It solves the problem of poor fixing effect of existing gas cylinder storage fixing brackets. However, when using the above technical solution, the fixing bracket is large and cannot be folded. The fixing bracket occupies a lot of space when transported to the nuclear power plant, resulting in a limited number of fixing brackets transported each time.

[0005] Therefore, those skilled in the art have provided a gas cylinder fixing bracket for nuclear power plants to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a gas cylinder fixing bracket for nuclear power plants to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A gas cylinder fixing bracket for a nuclear power plant includes a fixing frame, and a disassembly mechanism is provided on the outside of the fixing frame; The disassembly mechanism includes two first rotating shafts, each with a side plate fixedly connected to its outer surface. Two second rotating shafts are rotatably connected to the inner wall of the fixing frame, each with a base plate fixedly connected to its outer surface. A limiting plate is fixedly connected to the bottom surface of the fixing frame. A rectangular groove is provided on the left side of the fixing frame, and a rectangular block is slidably connected inside the groove. A partition plate is fixedly connected to the left side of the rectangular block, and two limiting blocks are fixedly connected to the front of the partition plate. Four sets of transmission plates are provided on the left side of the fixing frame, each with a clamping ring fixedly connected to its outer surface. The sides of two sets of transmission plates that are far apart from each other contact the sides of two side plates that are close to each other. The sides of the other two sets of transmission plates that are close to each other contact the front and back of the partition plate, respectively. Four storage slots are provided on the upper surface of the fixing frame, and two limiting slots are provided on the right side of the fixing frame.

[0008] As a further improvement of this utility model: both the front and back of the fixing frame are fixedly connected to fixing plates, and the inner wall of each fixing plate is rotatably connected to a rotating shaft.

[0009] As a further improvement of this utility model: a handle is fixedly connected to the outer surface of each of the rotating shafts, and the outer surface of each of the first rotating shafts is rotatably connected to the inner wall of the fixing frame.

[0010] As a further improvement of this utility model: the upper surface of the fixing frame has two slots, and each slot has a locking block inside.

[0011] As a further improvement of this utility model: the top ends of the two card blocks are fixedly connected to a top plate, and the bottom surface of the top plate is in contact with the upper surface of the fixing frame.

[0012] As a further embodiment of this utility model: two sets of force springs are fixedly connected to the inner walls of the two side plates and the inner wall of the partition plate. Two push blocks are fixedly connected to the right end of each set of force springs, and the right side of each push block is in contact with the left side of the transmission plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a rectangular groove, a transmission plate, a clamping ring, and a rectangular block in a coordinated manner. The clamping ring and transmission plate are manually pulled upwards and placed inside a storage slot on the upper surface of the fixed frame. The partition plate, fixed to the left side of the rectangular block, can be pulled out by the sliding connection of the rectangular block within the rectangular groove. Since two limiting blocks are fixedly connected to the front of the partition plate, it can slide into the limiting groove through these blocks, flattening the partition plate on the right side of the fixed frame. Then, a rotational force is applied to the bottom plate, causing it to fold to the left side of the fixed frame under the action of a second rotating shaft until it is parallel to the fixed frame. Similarly, a rotational force is applied to the two side plates, and the first rotating shaft fixed to the inner wall of the side plates rotates under the fixed inner wall, folding the two side plates to the left side of the bottom plate. The two side plates also remain parallel to the fixed frame, thus reducing the overall volume of the fixed frame and ensuring that it does not occupy a large amount of space during transportation to the nuclear power plant, allowing for the transport of more fixed frames at once.

[0016] Please see Figure 1-4 A gas cylinder fixing bracket for a nuclear power plant includes a fixing frame 1. A disassembly mechanism 2 is provided on the outer side of the fixing frame 1. The disassembly mechanism 2 includes two first rotating shafts 201. Fixing plates 4 are fixedly connected to both the front and back of the fixing frame 1. A rotating shaft 8 is rotatably connected to the inner wall of each fixing plate 4. By setting the fixing plates 4 and the rotating shafts 8, the rotating shafts 8 can be fixed by the fixing plates 4, providing a stable working position for the rotating shafts 8.

[0017] Each first rotating shaft 201 has a side plate 204 fixedly connected to its outer surface. The inner wall of the fixed frame 1 is rotatably connected to two second rotating shafts 213. Each second rotating shaft 213 has a base plate 212 fixedly connected to its outer surface. The bottom surface of the fixed frame 1 is fixedly connected to a limit plate 205. Each rotating shaft 8 has a handle 9 fixedly connected to its outer surface. The outer surface of each first rotating shaft 201 is rotatably connected to the inner wall of the fixed frame 1. By providing the handle 9, the device can be lifted by the handle 9, thus facilitating the handling of the device.

[0018] A rectangular groove 210 is provided on the left side of the fixed frame 1. A rectangular block 211 is slidably connected inside the rectangular groove 210. A partition plate 206 is fixedly connected to the left side of the rectangular block 211. Two limit blocks 207 are fixedly connected to the front of the partition plate 206. Four sets of transmission plates 202 are provided on the left side of the fixed frame 1. A clamping ring 203 is fixedly connected to the outer surface of each set of transmission plates 202. Two slots 7 are provided on the upper surface of the fixed frame 1. A locking block 6 is locked inside each slot 7. By setting the slots 7 and locking blocks 6, the external device can be connected to the top of the fixed frame 1 by locking the locking block 6 inside the slot 7, which has a good auxiliary effect.

[0019] Two sets of transmission plates 202 have their sides facing away from each other and their sides facing close to each other. The other two sets of transmission plates 202 have their sides facing close to each other and their sides facing the front and back of the partition plate 206, respectively. The upper surface of the fixed frame 1 has four sets of storage slots 209. The tops of the two clips 6 are fixedly connected to the top plate 3. The bottom surface of the top plate 3 is in contact with the upper surface of the fixed frame 1. By providing the top plate 3, the storage slots 209 on the upper surface of the fixed frame 1 can be covered by the top plate 3, preventing the clamping rings 203 and transmission plates 202 inside the storage slots 209 from shaking up and down due to the bumps of the transport vehicle.

[0020] Two limiting grooves 208 are provided on the right side of the fixed frame 1. Two sets of force springs 5 ​​are fixedly connected to the inner walls of the two side plates 204 and the inner wall of the partition plate 206. Two push blocks 10 are fixedly connected to the right end of each set of force springs 5. The right side of each push block 10 is in contact with the left side of the transmission plate 202. By setting the force springs 5 ​​and push blocks 10, the force springs 5 ​​can push the push blocks 10 to move towards the position of the transmission plate 202, thereby ensuring that the two transmission plates 202 can drive the clamping ring 203 to clamp gas cylinders of different sizes.

[0021] The working principle of this utility model is as follows: In use, the clamping ring 203 and the transmission plate 202 are manually pulled upwards and placed inside the storage slot 209 opened on the upper surface of the fixed frame 1. Then, through the connection relationship of the rectangular block 211 sliding inside the rectangular slot 210, the partition plate 206 fixed on the left side of the rectangular block 211 can be pulled out. Since there are two limiting blocks 207 fixedly connected to the front of the partition plate 206, it can slide into the limiting slot 208 through the two limiting blocks 207, flattening the partition plate 206 on the right side of the fixed frame 1. Then, a rotational force is applied to the bottom plate 212, and the bottom plate 212 is folded to the left side of the fixed frame 1 under the action of the second rotating shaft 213 until the bottom plate 212 is parallel to the fixed frame 1. Then, a rotational force is applied to the two side plates 204, and the first rotation is fixed by the inner wall of the side plates 204. The rotation of the inner wall of the fixed shaft 201 allows the two side plates 204 to be folded to the left side of the bottom plate 212. The two side plates 204 remain parallel to the fixed frame 1, thereby reducing the overall volume of the fixed frame 1 and ensuring that the fixed frame 1 does not occupy a lot of space during transportation to the nuclear power plant. This allows for the transportation of more fixed frames 1 at once. When it is necessary to fix the gas cylinder inside the fixed frame 1, the above operation can be repeated in reverse to reset the fixed frame 1. When placing the gas cylinder inside the fixed frame 1, one hand needs to pull a clamping ring 203, and then the gas cylinder is placed between the two clamping rings 203. Releasing the clamping rings 203 will allow the clamping rings 203 to clamp gas cylinders of different sizes under the action of the force spring 5, thereby effectively avoiding the problem that the fixed frame 1 occupies a large area and is inconvenient to transport when the device is in use.

[0022] 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.
