[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] A fire extinguisher capable of preventing a spray nozzle from swinging comprises a fire extinguisher body 1, a pressure gauge 2, a tube body 3, and a hose 5. The fire extinguisher body 1 is filled with dry powder. The upper end opening of the fire extinguisher body 1 is connected to the tube body 3. The pressure gauge 2 is provided at the connection between the tube body 3 and the fire extinguisher body 1. The tube body 3 is connected to one end of the fire extinguisher body 1, and the other end is interference-fitted with the hose 5. The other end of the hose 5 connected to the tube body 3 is fixedly provided with a spray nozzle 13.

[0020] The outer side surface of the tube body 3 is interference-fitted with one end of the fixed tube 4, and the inner side of the other end of the fixed tube 4 is bolted to a limiting mechanism to limit the position of the hose 5;

[0021] The other end of the limiting mechanism connected to one end of the fixing pipe 4 is pin-connected to a fixing mechanism to fix the injection head 13 .

[0022] Specifically, a first threaded hole is provided on the fixed tube 4 to be threadedly connected with a fixing bolt 6, and a second threaded hole is provided on the limiting mechanism to be bolted to the fixed tube 4. The limiting mechanism includes a first limiting tube 7 and a second limiting tube 9. The fixed tube 4 is bolted to the first limiting tube 7. The first limiting tube 7 is connected to one end of the fixed tube 4, and the other end thereof is fixedly provided with a telescopic hose 8 to be connected to the second limiting tube 9. The sum of the length of the first limiting tube 7 and the length of the second limiting tube 9 is less than the length of the hose 5. The fixing mechanism includes a connecting rod 12, a mounting block 11, and a clamping jaw 10. The outer side pin of the limiting mechanism is connected to one end of the connecting rod 12, and the other end of the connecting rod 12 is fixedly provided with a mounting block 11. The bottom end of the mounting block 11 is bolted to the clamping jaw 10. The clamping jaw 10 includes a first claw arm and a second claw arm. A compression spring is provided between the first claw arm and the second claw arm to increase the force of the clamping jaw 10 on the injection head 13.

[0023] This embodiment provides a specific structural connection and use process for a fire extinguisher that can prevent the spray nozzle from swinging; a fire extinguisher that can prevent the spray nozzle from swinging, such as Figure 1 As shown in a side cross-sectional view of a fire extinguisher capable of preventing the nozzle from swinging, the fire extinguisher comprises a fire extinguisher body 1, a pressure gauge 2, a pipe body 3 and a hose 5. The fire extinguisher body 1 is filled with dry powder, the upper end opening of the fire extinguisher body 1 is connected to the pipe body 3, and a pressure gauge 2 is provided at the connection between the pipe body 3 and the fire extinguisher body 1 to detect the pressure of the fire extinguisher body 1; the hose 5 is rotated into the other end of the pipe body 3 connected to the fire extinguisher body 1 until it is tightened; the other end of the hose 5 is connected to the spray head 13;

[0024] The outer side surface of the tube body 3 is interference-fitted with a fixed tube 4 to connect a limiting mechanism, which limits the position of the hose 5; the limiting mechanism includes a first limiting tube 7 and a second limiting tube 9, a first threaded hole is opened on the fixed tube 4, and a second threaded hole is opened on the first limiting tube 7. Figure 2 of Figure 1 As shown in the enlarged view of part A, the fixing bolt 6 passes through the first threaded hole and the second threaded hole in sequence, thereby fixing the fixing tube 4 and the first limiting tube 7;

[0025] A stainless steel telescopic hose 8 is welded to the other end of the first position-limiting tube 7 connected to one end of the fixed tube 4. A second position-limiting tube 9 is welded to the other end of the telescopic hose 8. By adjusting the length and angle of the telescopic hose 8, the direction of the internal hose 5, i.e., the spraying direction, can be controlled.

[0026] like Figure 3 of Figure 1As shown in the enlarged view of part B, the outer side of the other end of the second limiting tube 9 is fixed with a connecting pin to the connecting rod 12, and the other end of the connecting rod 12 is welded with a mounting block 11. The bottom end of the mounting block 11 is bolted with a clamping claw 10 to fix the injection head 13, so that the injection head 13 will not swing when the fire extinguisher is used, and can accurately aim at the fire source for extinguishing the fire.

[0027] The clamping jaw 10 includes a first claw arm and a second claw arm, which are symmetrically hinged to two opposite sides of the mounting block 11; a compression spring is provided between the first claw arm and the second claw arm, which can play a certain buffering role when the clamping jaw 10 fixes the injection head 13.

[0028] Usage process: Before using the fire extinguisher, check the pointer on the pressure gauge 2. If it is normal, you can use the fire extinguisher and tighten the fixing bolts 6 to fix the fixing tube 4 and the first limit tube 7; use the clamping claws 10 to fix the spray head 13; according to the direction of the fire source and the angle of the firefighter's posture holding the fire extinguisher, adjust the angle of the telescopic hose 8 to control the direction of the internal hose 5; pull out the safety pin at the upper end of the fire extinguisher body 1, hold the handle, aim the spray head 13 at the fire source, and then press the handle to extinguish the fire.

[0029] After using the fire extinguisher, stop pressing the handle, insert the safety pin, and adjust the telescopic hose 8 to its initial position; if the spray head 13 needs to be replaced, the clamping jaws 10 need to be manually adjusted in the opposite direction. Under the action of the compression spring between the two claw arms, the spray head 13 is removed and restored to its initial state; after replacing the spray head 13, the two claw arms in the clamping jaws 10 are manually set on both sides of the spray head 13. At this time, the compression spring is stretched, so that the clamping jaws 10 have a tighter force on the spray head 13, thereby ensuring the stability of the spray head 13 during the fire extinguishing process and improving the efficiency of fire extinguishing.

[0030] The above-mentioned implementation manner is not a limitation of the present invention, and the present invention is not limited to the above-mentioned examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
