Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishers, in particular to a fire extinguisher which is easy to move. Background Art

[0002] A pressure-type fire extinguisher is a fire extinguisher with internal pressure. When a fire occurs, the fire can be controlled to a certain extent. When ordinary fire extinguishers are stored, they are placed directly anywhere, which makes them easy to collapse, roll, and be damaged. Existing fire extinguisher storage boxes are added. When not in use, the fire extinguisher is placed in the fire extinguisher storage box to prevent the fire extinguisher from collapsing. A Chinese patent discloses a pressure-type fire extinguisher (authorization announcement number CN221084495U). This patent technology discloses a pressure-type fire extinguisher, including a pressure-type fire extinguisher body, a limiting mechanism and a storage mechanism. The limiting mechanism is located at the outer end of the pressure-type fire extinguisher body, and the storage mechanism is located at the outer end of the pressure-type fire extinguisher body. The limiting mechanism includes a fixed base, a screw hole, a screw, a knob, an arc-shaped splint, an arc-shaped anti-sliding block and a brake wheel. The pressure-type fire extinguisher is equipped with a limiting mechanism, which facilitates the placement of the pressure-type fire extinguisher body through the fixed base, and the brake wheel facilitates the movement of the fixed base, thereby facilitating the movement of the pressure-type fire extinguisher body. When the pressure-type fire extinguisher body needs to be moved and stored, it can be directly connected to the fixed base and moved together, without the need to set up an additional fire extinguisher storage box, which is more convenient and economical. The fire extinguisher storage box is additional, and there is no need to take the time and effort to disassemble and then install the fire extinguisher storage box. This patented technology solves the problem that the position of the fire extinguisher storage box is fixed, and when the fire extinguisher needs to be moved to another suitable position, an additional fire extinguisher storage box needs to be added, which wastes costs, or the fire extinguisher storage box needs to be disassembled and then installed before the fire extinguisher is stored, which is not convenient enough.

[0003] However, in the prior art, larger capacity fire extinguishers are not convenient to move on the stairs of the fire passage due to their large size and weight. It is necessary to solve the problem in the prior art that the height of the moving wheels can be adjusted according to the height of the stairs of the fire passage to facilitate the movement of the fire extinguisher.

[0004] Therefore, those skilled in the art provide a thin and tall fire extinguisher to solve the problems raised in the above background technology. Utility Model Content

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The examples of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Numerous modifications and variations will be apparent to those skilled in the art. The examples are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0025] For examples, see Figures 1 to 5 In this embodiment, a fire extinguisher that is easy to move is provided, comprising: a mobile frame 1; side panels 2 are integrally fixed to both ends of the surface of the mobile frame 1, and the bottom side walls of the two side panels 2 are equipped with a mobile structure 3;

[0026] The movable structure 3 includes a fixed angle plate 301 fixedly mounted on the outer wall of the side plate frame 2. A load-bearing shaft 302 is rotatably mounted on the inner wall of the fixed angle plate 301. A mounting frame 303 is rotatably mounted on the outer side of the load-bearing shaft 302. The inner wall of the mounting frame 303 is annularly and equidistantly mounted with three adjusting screws 306.

[0027] An adjusting screw 308 is helically driven within the adjusting screw 306, and a movable wheel frame 309 is fixedly mounted on one end of the adjusting screw 308. The fire extinguisher body 6 is positioned between the two side frame members 2. A movable wheel 310 is rotatably mounted within the movable wheel frame 309 for movement. A helical gear ring 307 is fixedly mounted on the outer wall of the adjusting screw 306, meshing with a helical gear 305.

[0028] An adjustment rod 304 is fixedly mounted at the center of the helical gear 305. The inner end of the adjustment rod 304 pivots through the outside of the bearing shaft 302 and is fixedly mounted with a handwheel. An inner slide 311 is fixedly mounted on the outer wall of the movable wheel frame 309. The outer sliding frame 312 constrains the sliding movement of the inner slide 311, which is fixedly mounted on the outer wall of the mounting frame 303. A hand lever screw 4 is helically driven on the inner wall of the top of the side panel frame 2. A locking ring frame 5 is rotatably mounted on the inner end of the hand lever screw 4.

[0029] A sliding frame 8 is slidingly provided on the inner side of the side plate frame 2, and a hand rod screw 2 7 is rotatably installed on the inner wall of the sliding frame 8. There is a spiral transmission relationship between the hand rod screw 2 7 and the side plate frame 2, and a positioning side plate 9 is fixedly installed at one end of the inner side of the sliding frame 8.

[0030] According to the above embodiment, the working principle of the present invention is:

[0031] The fire extinguisher body 6 is placed on the mobile frame 1, and the hand lever screw rod 4 is manually rotated so that the hand lever screw rod 4 is spirally driven along the side frame 2, so that the locking ring frame 5 contacts the fire extinguisher body 6, and the two ends of the locking ring frame 5 are fixed by the external mounting bolts, so that the upper position of the fire extinguisher body 6 can be fixed between the two side frame 2;

[0032] The lower part of the fire extinguisher body 6 is manually rotated by the hand lever screw rod 2 7, so that the hand lever screw rod 2 7 is spirally driven along the side plate frame 2, driving the positioning side plate 9 of the sliding frame 8 to fix the lower part of the fire extinguisher body 6 on the mobile frame 1;

[0033] The movable wheel body 310 can be moved on the stair steps of the fire passage according to the fire extinguisher body 6, and the height position of the movable wheel body 310 can be adjusted according to the height of the stair steps of the fire passage. When adjusting the height, the hand wheel is manually rotated to drive the adjusting rod 304 to rotate. The rotating adjusting rod 304 can drive the bevel gear 305 to rotate. The rotating bevel gear 305 engages with the bevel gear ring 307. The bevel gear ring 307 drives the three adjusting screw barrels 306 to rotate on the inner wall of the mounting frame 303 respectively. The adjusting screw barrel 306 can then drive the inner adjusting screw 308 to spirally transmit the adjusting screw 308. The adjusting screw 308 moves along the adjusting screw barrel 306, and the height of the movable wheel frame 309 and its movable wheel body 310 can be adjusted.

[0034] When the movable wheel frame 309 moves, the inner slide plate 311 can move and limit along the inner side of the outer slide frame 312.
