[0034] The pressing plate 113 is matched with the rectangular groove formed in the supporting disc 104, and is used for limiting the movement of the pressing plate 113.

[0035] The surface of one group of side plates 106 is fixed with a mounting seat 116 through bolts, one side of the mounting seat 116 is provided with a square slot, the mounting seat 116 is provided with a clamping rod 117 at the square slot, the clamping rod 117 is rotationally connected with the mounting seat 116 through a hinge shaft, the surface of the hinge shaft is provided with a reset torsion spring 118, the two ends of the reset torsion spring 118 are fixedly connected with the clamping rod 117 and the mounting seat 116 respectively, the side of the movable disc 109 close to the clamping rod 117 is provided with a plurality of groups of clamping grooves 119 arranged in a ring shape at equal intervals;

[0036] When the clamping rod 117 is clamped in one group of clamping grooves 119, the movable disc 109 is limited and locked.

[0037] In the embodiment: when the fire nozzle 101 needs to be positionally locked with the fire extinguishing area, first, two groups of pressing plates 113 can be pressed at the same time, so that the pressing plates 113 slide on the fixed rods 111, the springs 112 are compressed through the pressing plates 113, the pressing plates 113 drive the bolts 114 to be separated from the lock grooves 115, the locking of the rotating discs 105 is released, so that when the rotating discs 105 are rotated, the fire nozzle 101 can be driven to be horizontally adjusted under the connection of the side plates 106, when the fire nozzle 101 is horizontally corresponding to the fire extinguishing area, the pressing plates 113 are released, at this time, the springs 112 rebound and drive the bolts 114 to be inserted into the matching corresponding lock grooves 115, the position of the rotating discs 105 is locked;

[0038] When the fire nozzle 101 is adjusted in up-down angle, first, one end of the clamping rod 117 is pressed, so that the clamping rod 117 rotates around the hinge shaft as the center, and drives the reset torsion spring 118 to produce elastic deformation, in this process, the other end of the clamping rod 117 is lifted and separated from the clamping grooves 119 of the movable disc 109, so that the locking of the movable disc 109 is released, so that the fire nozzle 101 can be adjusted in up-down angle, until the fire nozzle 101 is corresponding to the fire extinguishing area in height, then the pressing of the clamping rod 117 is released, at this time, the reset torsion spring 118 resets and clamps the clamping rod 117 in the clamping grooves 119 of the movable disc 109, to lock the position of the movable disc 109, through the up-down angle and horizontal angle of the fire nozzle 101, the stability of the fire nozzle 101 to the specified fire extinguishing area is improved.

[0039] It should be noted that: because the fire nozzle 101 can be disassembled and sleeved on the fixed ring 108, and the fixed ring 108 can be flexibly folded according to the fire nozzle 101, when the fire water is opened, the fire nozzle 101 sprays instantaneously, and in general, if the direction of the water flow is away from the support 103, due to the action of the reaction force, the fire nozzle 101 will have a tendency to retreat. This is because when the water flow is sprayed at high speed from the fire nozzle 101, according to Newton's third law (action and reaction are equal and opposite), the fire nozzle 101 will be subjected to a force in the opposite direction, thereby producing a tendency to retreat. Before the fire nozzle 101 sprays water, the fire nozzle 101 can be adjusted in angle, so that the rear end of the fire nozzle 101 (connected to the water hose end) is inclined downward, and when subjected to the reaction force, the reaction force towards the ground will be generated, at this time the support 103 will not appear to be tilted. At the same time, during this process, the staff is located at the position of the support 103, and the foot can step on the support 103 to improve the stability of the placement of the support 103, so as to avoid the tilting condition.

[0040] It should be noted that: the fixed ring 108 is threadedly connected with an extrusion bolt through the threaded hole opened on the fixed ring 108, the fire nozzle 101 is sleeved on the fixed ring 108, and the fire nozzle 101 is pressurized and installed and fixed by the extrusion bolt. The fire nozzle 101 can be fixed and installed in the fixed ring 108, and this structure can realize the disassembly and assembly operation of the fire nozzle 101.

[0041] The working principle and use process of the utility model: the chemical safety fire fighting device, when extinguishing, first of all, the support 103 is placed on the ground and supports, the water supply pipe 102 is connected with the fire water valve to realize water supply operation, then the fire nozzle 101 is discharged to carry out the extinguishing operation, when extinguishing, handheld movable handle 110, movable connecting plate 107 can be moved to the center of the circle and be angularly rotated, connecting plate 107 rotates on the side plate 106 through the movable disc 109, when the movable handle 110 is horizontally rotated, under the connection of connecting plate 107 and side plate 106, further through the side plate 106, the rotating disc 105 is driven to rotate on the support disc 104, so that the fire nozzle 101 can be angularly rotated and adjusted flexibly and multidirectionally through the handheld movable handle 110, and the fire nozzle 101 can be supported, without the need for the fire personnel to hold the fire nozzle 101 for a long time to spray water, reducing the rapid consumption of the physical strength of the operator, can continuously carry out effective water spraying operation, without affecting the stability and accuracy of water spraying, improving the use effect of the device; when the fire nozzle 101 needs to be position-locked with the fire extinguishing area, first of all, two sets of pressing plates 113 can be pressed simultaneously, so that the pressing plate 113 slides on the fixed rod 111, the spring 112 is compressed through the pressing plate 113, so that the pressing plate 113 drives the bolt 114 to separate from the lock slot 115, the locking of the rotating disc 105 is released, so that when the rotating disc 105 rotates, under the connection of the side plate 106, the fire nozzle 101 can be driven to be horizontally angularly adjusted, so that when the fire nozzle 101 horizontally corresponds with the fire extinguishing area, the pressing plate 113 is released, at this time, the spring 112 rebounds and drives the bolt 114 to be inserted into the matching corresponding lock slot 115, the position of the rotating disc 105 is locked; when the fire nozzle 101 is angularly adjusted up and down, first of all, one end of the clamping rod 117 is pressed, so that the clamping rod 117 rotates around the hinged shaft as the center of the circle and drives the reset torsional spring 118 to produce elastic deformation, in this process, the other end of the clamping rod 117 is raised and separated from the clamping groove 119 of the movable disc 109, so that the locking of the movable disc 109 is released, so that the fire nozzle 101 can be angularly adjusted up and down, until the fire nozzle 101 corresponds with the fire extinguishing area in height, then the pressing of the clamping rod 117 is released, at this time, the reset torsional spring 118 resets and clamps the clamping rod 117 in the clamping groove 119 of the movable disc 109, to lock the position of the movable disc 109, through the up-and-down angle and horizontal angle of the fire nozzle 101, the stability of the fire nozzle 101 to the specified fire extinguishing area is improved.
