[0041] Embodiment 1:

[0042] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 An embodiment of the present invention is a fire extinguisher with a foldable nozzle, comprising a cylinder 1, a connecting pipe 6 is connected to the top of the cylinder 1, a positioning block 7 is connected to one end of the connecting pipe 6, a slider 8 is inserted at one end of the positioning block 7, a pipe 14 is fixedly connected to one end of the positioning block 7, a through hole is opened on the outside of the pipe 14, the slider 8 is set to an L-shaped structure, and openings are opened at both ends, a plurality of positioning grooves 17 are opened on the side of the positioning block 7 close to the slider 8, the positioning grooves 17 are set to an arc structure, the positioning block 7 is set to a structure with a cavity 22 inside, a nozzle 9 is connected to one end of the slider 8, a multi-directional nozzle 10 is connected to one end of the nozzle 9, a pipe 14 is connected to one end of the slider 8 close to the positioning block 7, and a through hole is opened on the outside of the pipe 14, such as Figure 4 As shown, a mounting groove 16 is provided on one side of the slider 8 close to the positioning block 7 , a spring 15 is fixedly connected to the inner wall of the mounting groove 16 , a steel ball 18 is fixedly connected to one end of the spring 15 , and one side of the steel ball 18 is inserted into the positioning groove 17 .

[0043] The slider 8 is turned by hand, and the positioning groove 17 pushes the steel ball 18 to retract when the slider 8 rotates, so that the slider 8 can rotate to adjust the angle of the nozzle 9 and the multi-directional nozzle 10. When the slider 8 rotates to a certain angle, the spring 15 pushes the steel ball 18 into the positioning groove 17, limiting the slider 8 to achieve folding of the nozzle 9 and the multi-directional nozzle 10.

[0044] A plurality of O-rings 13 are sleeved on the outer side of one end of the slider 8 close to the positioning block 7 . The O-rings 13 are made of rubber material. The O-rings 13 are sleeved on the outer side of the slider 8 to seal the gap between the slider 8 and the positioning block 7 .

[0045] A lifting handle 3 is installed on one side of the top of the cylinder 1, and a pressure handle 4 is provided on the top of the lifting handle 3. The pressure handle 4 is installed on one side of the top of the cylinder 1, and a pressure gauge 5 is fixedly connected to the front side of the top of the cylinder 1. The pressure handle 4 and the lifting handle 3 are held by hand so that the liquid inside the cylinder 1 can be sprayed out from the top of the cylinder 1 and transported to the inside of the connecting pipe 6 and the nozzle 9, and sprayed out from the inside of the multi-directional nozzle 10 at the same time. The pressure inside the cylinder 1 can be judged by observing the value on the pressure gauge 5.

[0046] A bracket 2 is sleeved on the outside of the barrel 1, and a fixing groove is opened on one side of the bracket 2. The fixing groove is clamped on the outside of the nozzle 9. When the nozzle 9 is not in use, the nozzle 9 can be clamped into the fixing groove and fixed to the bracket 2 to store the nozzle 9.

[0047] Limiting grooves 20 are provided on both sides of the installation groove 16, and limiting blocks 19 are slidably connected inside the two limiting grooves 20. One end of the two limiting blocks 19 is fixedly connected to both sides of the steel ball 18. When the spring 15 pushes the steel ball 18 to move inside the installation groove 16, the steel ball 18 will drive the limiting blocks 19 to move inside the limiting groove 20. When the limiting blocks 19 contact the inner wall of the limiting groove 20, the steel ball 18 will be limited to prevent the spring 15 from completely pushing the steel ball 18 out of the installation groove 16.

[0048] A base 11 is fixedly connected to the bottom end of the cylinder 1, and is arranged as a cavity 22 structure with an opening at the bottom. A flip block 24 is rotatably connected inside the base 11. The diameter of the flip block 24 is slightly smaller than the cavity 22 structure of the base 11. One side of the flip block 24 is arranged as a conical structure. Grooves 25 are provided on both sides of the flip block 24. A cavity 22 is provided on one side of the inner wall of the base 11, and a spring 21 is fixedly connected to one side. A protrusion 23 is fixedly connected to one end of the spring 21, and one end of the protrusion 23 is inserted into the groove 25. A groove 27 is provided on the inner bottom wall of the cavity 22, and a push block 26 is slidably connected inside the groove 27, and one side of the push block 26 is fixedly connected to the bottom end of the protrusion 23.

[0049] When it is necessary to break the window glass for escape, the push block 26 can be pulled by hand to retract it into the cavity 22, and then the flip block 24 can be rotated to flip the conical surface of the flip block 24 out, and then the push block 26 can be released to allow the spring 21 to push the protrusion 23 into the groove 25 to fix the flip block 24, and then the cylinder 1 can be picked up and the conical surface of the flip block 24 can be used to hit the glass to break the glass on the window for escape.

[0050] When the fire extinguisher is needed, the slider 8 can be rotated by hand. When the slider 8 rotates, the arc-shaped positioning groove 17 will push the steel ball 18 to retract, so that the slider 8 can rotate to adjust the angle of the nozzle 9 and the multi-directional nozzle 10. When the slider 8 rotates to a certain angle, the spring 15 will push the steel ball 18 into the positioning groove 17, limit the slider 8 to realize the folding of the nozzle 9 and the multi-directional nozzle 10, and then hold the pressure handle 4 and the lifting handle 3 by hand to allow the liquid inside the cylinder 1 to enter the connecting pipe 6 from the top of the cylinder 1, and enter the positioning block 7 from the connecting pipe 6, and then enter the slider 8 from the through hole of the pipeline 14, and then pass through the nozzle 9 and spray out from the multi-directional nozzle 10. When the fire extinguisher is not in use, the nozzle 9 can be clamped into the fixed groove to store the nozzle 9.

[0051] Embodiment 2:

[0052] Reference Figure 2 and Figure 8 The difference from the first embodiment is that a through hole is opened on one side of the base 11, and a bolt 12 is threadedly connected inside the through hole on one side of the base 11, and one end of the bolt 12 is threadedly connected inside the groove 25. When it is necessary to break the window glass for escape, the bolt 12 can be rotated to remove the bolt 12 from the inside of the groove 25, and then the flip block 24 is rotated to flip the conical surface of the flip block 24 out, and the bolt 12 is rotated in the opposite direction to make the thread enter the groove 25 again to fix the flip block 24, and then the cylinder 1 is picked up and the conical surface of the flip block 24 is used to hit the glass to break the glass on the window for escape.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
