[0002] Firefighting material racks, also known as firefighting equipment racks, are equipment used to store and display firefighting equipment. They are essential for fire safety management. For coal mines, due to the narrow space underground, it is difficult to place large firefighting equipment. Therefore, fire extinguishers, engineer shovels and other firefighting equipment are often equipped underground to improve the safety of coal mines. In order to store these firefighting equipment, firefighting material racks are needed.

[0003] When the fire-fighting material rack is in use, it is stably placed underground by an adjustable screw, and a fire extinguisher and an engineer shovel are placed on the material rack. However, in the existing fire-fighting material rack, in order to ensure the placement stability of the fire extinguisher, the fire extinguisher is usually placed in the frame from top to bottom, and it needs to be fully lifted up to be taken out for use. When a fire occurs, the staff, due to anxiety, starts to apply force in the horizontal direction after the fire extinguisher is not completely taken out, which often causes the fire extinguisher to not be taken out immediately, thereby affecting the rapid fire extinguishing. At the same time, in the existing fire-fighting material rack, the hook for hanging the engineer shovel is fixedly set, and the position cannot be adjusted according to the actual situation, and the flexibility of use is poor.

[0019] When using the fire-fighting material rack, the support frame 1 is placed underground through the adjusting screw 2, and the adjusting screw 2 is adjusted underground through the adjusting wheel 3 so that the entire support frame 1 is placed stably, the fire extinguisher 7 is placed on the placement structure 4, and the engineer shovel is suspended on the suspension structure 6 on the cross bar 5. During suspension, the position of the suspension structure 6 can be adjusted according to actual conditions. During operation, the tightening ring 606 is moved through the control rod 607, and the tightening ring 606 moves along the connecting rod 603 toward the direction of the end plate 604 and compresses the spring 605. After the tightening ring 606 gives way, the movable block 601 is moved to a suitable position along the strip hole 8, and then the control rod 607 is released. Under the action of the spring 605, the tightening ring 606 abuts against the cross bar 5, which can ensure the stability of the movable block 601, and then the engineer shovel can be suspended on the inclined suspension rod 602. When the engineer shovel is needed, the engineer shovel can be quickly removed from the external interface directly, and the operation is convenient.

[0020] Through the above implementation scheme, the placement structure 4 includes a fixed plate 401, a removable plate 402 and a rotating fastening assembly 405, the fixed plate 401 is connected to the removable plate 402, and the rotating fastening assembly 405 is installed between the fixed plate 401 and the removable plate 402. The placement structure 4 also includes a clearance hole 403 and a circular hole 404, the clearance hole 403 is arranged on the fixed plate 401 and the removable plate 402, and the fixed plate 401 and the removable plate 402 are fixedly connected by screws, and the circular hole 404 is opened at the contact position between the fixed plate 401 and the removable plate 402, and the rotating fastening assembly 405 includes a placement seat 4051, a pin shaft 4052, a tightening spring piece 4053, a weight block 4054, a support rod 4055 and a limiting ring 4056, the placement seat 4051 is fixedly connected to the pin shaft 4052, and the pin shaft 4052 is arranged in the circular hole 404, and the tightening spring piece 4053 is embedded in the placement seat On the inner wall of 4051, the weight block 4054 is fixed to the lower end of the placement seat 4051, the support rod 4055 is fixedly connected to the limit ring 4056, and the support rod 4055 is arranged at the upper end of the placement seat 4051. Through the placement structure 4, the fire extinguisher 7 is placed in the rotating fastening assembly 405, and the placement seat 4051 in the rotating fastening assembly 405 is installed in the makeshift hole 403 between the fixed plate 401 and the removable plate 402 through the pin shaft 4052. When the fire extinguisher 7 is placed normally, due to the weight increase effect of the weight block 4054, the fire extinguisher 7 can be placed vertically. After a fire occurs, when taking the fire extinguisher 7, the rotating fastening assembly 405 can be rotated to a tilted state through the pin shaft 4052, which is convenient for quickly taking out the fire extinguisher 7 and is conducive to extinguishing the fire as soon as possible. The placement seat 4051 is internally provided with a pressing spring piece 4053 to ensure the placement stability of the fire extinguisher 7.

[0021] When installing the placement structure 4, the placement seat 4051 in the rotary fastening assembly 405 is set on the fixed plate 401, and then the detachable plate 402 is installed on the fixed plate 401 through screws. The placement seat 4051 is located in the relief holes 403 of the two plates. At the same time, the pin shaft 4052 is located in the round hole 404. Under the action of the weight increasing block 4054, the placement seat 4051 drives the support rod 4055 and the limit ring 4056 to be in a vertical state. After the placement structure 4 is installed, the fire extinguisher 7 is placed from top to bottom. The lower end of the fire extinguisher 7 passes through the limit ring 4056 and enters the placement seat 4051. The abutting elastic piece 4053 abuts and fixes the fire extinguisher 7 to ensure the placement stability of the fire extinguisher 7. When the fire extinguisher 7 is placed, under the action of the weight increasing block 4054, the entire rotary fastening assembly 405 and the fire extinguisher 7 are still in a vertical state, ensuring the normal placement of the fire extinguisher 7. When the fire extinguisher 7 needs to be used, the user holds the upper end of the fire extinguisher 7 and applies an external force to the rotary fastening assembly 405. The placement seat 4051 rotates on the fixed plate 401 and the detachable plate 402 through the pin shaft 4052. When the rotary fastening assembly 405 rotates to an inclined state, the fire extinguisher 7 can be quickly withdrawn and then used.
