[0031] like Figure 1-11 As shown:

[0032] A fire extinguisher comprises a fire extinguisher bottle 201 with a ring frame 202 at the lower part, a spray pipe 203 is provided on the upper side of the fire extinguisher bottle 201, and a rotating cover 204 for controlling the opening or closing of the fire extinguisher bottle 201 is rotatably provided on the upper end of the fire extinguisher bottle 201, two vertical rods 102 are penetrated on the ring frame 202, a support plate 101 is fixed at the lower end of the two vertical rods 102, two rollers 105 are rotatably provided at one end of the support plate 101, a support plate 106 is fixed at the other end of the support plate 101, a pull plate 401 is rotatably provided at the upper ends of the two vertical rods 102, and a horizontal pull rod 402 is fixed between the two pull plates 401.

[0033] The fire extinguisher bottle 201 forms a limit with the two vertical rods 102 through the ring frame 202, and then the lower end of the fire extinguisher bottle 201 falls on the supporting plate 101, and then the fire extinguisher bottle 201 is supported and placed through the two rollers 105 and the supporting plate 106. When the fire extinguisher bottle 201 needs to be transferred, the horizontal pull rod 402 is pulled, so that the two pull plates 401 pull the two vertical rods 102, so that the two vertical rods 102 are tilted, and then the fire extinguisher as a whole is in contact with the ground through the two rollers 105, and then continue to pull, so that the fire extinguisher as a whole can be moved through the two rollers 105, saving time and effort;

[0034] When extinguishing a fire, the rotating cover 204 is rotated to open the fire extinguisher bottle 201, so that the fire extinguishing material in the fire extinguisher bottle 201 is sprayed out through the spray pipe 203 to extinguish the fire.

[0035] Further:

[0036] An extension tube 206 is slidably sleeved on the outside of the injection tube 203 .

[0037] By pulling the extension tube 206 to slide on the spray tube 203, the spray tube 203 is extended, so that the spray direction can be better controlled. When the fire extinguisher bottle 201 is not moved, the spray range is increased, and the use is more convenient.

[0038] Further:

[0039] The ring frame 202 is provided with an elastic opening clamp 208 on the side of the injection pipe 203 , and the extension pipe 206 can slide into the elastic opening clamp 208 .

[0040] When not in use, the extension tube 206 is slid into the elastic opening clamp 208 to clamp the extension tube 206, ensuring the overall neatness of the fire extinguisher while making the extension tube 206 and the injection tube 203 in the shortest state to prevent the extension tube 206 from sliding freely in the injection tube 203 and causing obstruction.

[0041] like Figure 1-11 As shown:

[0042] A cross bar frame 403 is provided between the two pull plates 401 for limiting sliding. Two plug pins 404 are provided at the end of the cross bar frame 403 away from the transverse tie rod 402. Two insertion holes 207 are provided on the rotating cover 204. A spring I 406 is provided between the cross bar frame 403 and the transverse tie rod 402. When the pull plate 401 rotates to extend the vertical rod 102 in the upward direction, the two plug pins 404 are respectively inserted into the two insertion holes 207.

[0043] When not in use, the two plug pins 404 are respectively inserted into the two insertion holes 207 by the elastic force of spring I 406, thereby locking the rotating cover 204 to prevent the rotating cover 204 from automatically rotating and causing leakage of the fire extinguisher. At the same time, through the locking of the plug pins 404 and the insertion holes 207, the coaxial locking of the pull plate 401 and the vertical rod 102 can be formed, that is, the horizontal tie rod 402 is located directly above the rotating cover 204, which is convenient for pulling the horizontal tie rod 402 to move the fire extinguisher.

[0044] Further:

[0045] A slide bar 405 penetrating the middle of the cross tie rod 402 is provided in the middle of the cross tie rod frame 403 . When the two plug pins 404 are respectively inserted into the two insertion holes 207 , a D-shaped plug pin 407 slides through the intersection of the cross tie rod 402 and the slide bar 405 .

[0046] The D-shaped latch 407 locks the relative positions of the cross-tie rod 402 and the slide rod 405, thereby forming a relative locking of the positions of the two latch pins 404 and the two insertion holes 207, ensuring that the latch pins 404 will not slide out of the insertion holes 207, and then ensuring that the rotating cover 204 will not rotate and the fire extinguisher will not leak.

[0047] Further:

[0048] The D-shaped latch 407 is D-shaped with an opening at one end.

[0049] One end of the D-shaped latch 407 is provided with an opening. When it is needed, the D-shaped latch 407 can be directly pulled in the opposite direction of the opening, and the D-shaped latch 407 will deform itself and slide down from the horizontal tie rod 402. Then, while holding the horizontal tie rod 402, use your fingers to hook the horizontal bar frame 403 upwards to make the two latch pins 404 slide out of the two sockets 207, and then the rotating cover 204 can be rotated to open the fire extinguisher.

[0050] like Figure 1-11 As shown:

[0051] An open ring 103 is fixed to the upper ends of the two vertical rods 102, a ring 301 is slidably mounted on the middle part of the fire extinguisher bottle 201, a square seat 302 is fixed to one end of the ring 301, a middle frame 501 is mounted on the square seat 302, the middle frame 501 is located between the open ring 103 and the ring frame 202, and the middle frame 501 has two interlocking plates 502 that rotate with the open ring 103 and the ring frame 202 respectively.

[0052] Since the open ring 103 is fixed to the two vertical rods 102, the ring frame 202 is fixed to the fire extinguisher bottle 201 and is slidably connected to the two vertical rods 102, the middle frame 501 is pulled away from the fire extinguisher bottle 201, and the four linkage plates 502 are pulled, so that the open ring 103 and the ring frame 202 are close to the sleeve ring 301, and in the process of approaching, the ring frame 202 will drive the fire extinguisher bottle 201 to rise, thereby adjusting the horizontal height of the fire extinguisher bottle 201, so that the fire extinguisher bottle 201 can reach a relatively high fire point to perform a fire extinguishing operation;

[0053] Further:

[0054] A spring II 104 is provided between the ring frame 202 and the support plate 101 .

[0055] The elastic force of the spring II 104 will push the ring frame 202 upward, thereby saving more effort when raising the fire extinguisher bottle 201.

[0056] like Figure 1-11 As shown:

[0057] A square rod 303 is rotated on the square seat 302, and a double-headed rod 304 is horizontally penetrated on the square rod 303, and a spring III 305 is provided between the square rod 303 and the double-headed rod 304, so that the double-headed rod 304 is pressed against the end of the square seat 302, and a limiting frame 205 is fixed on the upper part of the fire extinguisher bottle 201. When the middle frame 501 is located on the square seat 302, the square rod 303 is rotated upward to make the double-headed rod 304 rest on the limiting frame 205, so that the lower end of the fire extinguisher bottle 201 is locked in a fit state with the support plate 101.

[0058] Due to the existence of spring II 104, in order to prevent the spring II 104 from pushing the fire extinguisher bottle 201 up when not in use, a square rod 303 is provided. When the square rod 303 and the square seat 302 are tilted, the middle frame 501 can be limited on the fitted square seat 302. At this time, the four linkage plates 502 are all in a vertical state, thereby ensuring that the lower end of the fire extinguisher bottle 201 is in a fitted state with the support plate 101, that is, the fire extinguisher bottle 201 is at the lowest end. At this time, when the square rod 303 is rotated upward to a vertical state, the double-headed rod 304 can be pushed by the spring III 305 to a hooked state with the limit frame 205, thereby forming a lock in this state;

[0059] When the fire extinguisher bottle 201 needs to be raised, the double-headed rod 304 is pulled to overcome the sliding of the spring III 305 and disengage from the limit frame 205, and the square rod 303 can be rotated to make the square rod 303 coaxial with the square seat 302, so that the middle frame 501 can slide onto the square rod 303, thereby raising the fire extinguisher bottle 201.

[0060] Further:

[0061] A lock pin frame 503 is slidably arranged in the middle frame 501, and a spring IV 504 is arranged between the lock pin frame 503 and the middle frame 501. A plurality of lock holes are evenly arranged on the square rod 303, and the lock pin frame 503 is inserted into one of the lock holes to form a locking control on the rising height of the fire extinguisher bottle 201.

[0062] When the middle frame 501 slides on the square rod 303 to adjust and control the horizontal height of the fire extinguisher bottle 201, the relative limitation of the middle frame 501 and the square rod 303 can be achieved by inserting the pin rod of the locking pin frame 503 into the corresponding locking hole, thereby forming a locking control on the rising height of the fire extinguisher bottle 201. At the same time, through the setting of the spring IV504, the elastic force of the spring IV504 can ensure the stability of the pin rod of the locking pin frame 503 inserted into the corresponding locking hole.
