DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0023] Please refer to Figure 1 - Figure 5 A fire extinguishing water gun for fire rescue teaching in schools includes a high-pressure water gun 2 mounted on a teaching table 1. A mounting base 3 is connected to the teaching table 1. A support component is connected to the side of the mounting base 3 away from the teaching table 1. The support component includes two triangular support frames 4. A buffer component is connected between the two triangular support frames 4 and the mounting base 3. The end of each of the two triangular support frames 4 away from the mounting base 3 is connected to a mounting component. The high-pressure water gun 2 is mounted on the two triangular support frames 4 through the two mounting components.
[0024] like Figure 1 - Figure 5 As shown, the fire extinguishing water gun of this utility model for school fire rescue teaching is similar in structure to the existing high-pressure water gun for firefighting. The main improvement of this utility model is that by allowing students to practice with the high-pressure water gun 2, they can actually feel the powerful reaction force when the high-pressure water gun 2 sprays water, thereby improving their practical skills. Figures 1 to 5 As shown, the fire extinguishing water gun of this utility model for school fire rescue teaching is used by installing the mounting base 3 on the teaching table 1, and then installing the high-pressure water gun 2 on two triangular support frames 4 through the mounting components. When the high-pressure water gun 2 is used for teaching practice, when the high-pressure water gun 2 sprays high-speed water, it will provide a reaction force to the high-pressure water gun 2, causing the high-pressure water gun 2 to move backward. At this time, the buffer component can buffer the reaction force received by the high-pressure water gun 2, thereby avoiding the high-pressure water gun 2 suddenly moving backward and causing injury to the students behind. At the same time, the reduced reaction force can also make the students feel the strong reaction force when the high-pressure water gun 2 sprays water, so that the students can be more vigilant and make it easier for them to be mentally prepared in advance when they operate the high-pressure water gun 2 in the future. This will prevent beginners from being caught off guard by the strong reaction force when the high-pressure water gun 2 sprays water, improve the practical skills of beginners, improve the actual teaching effect, and eliminate the situation of theoretical discussion.
[0025] like Figure 1 - Figure 4 As shown, the mounting assembly includes a fixing ring 5 and a flipping ring 6. The fixing ring 5 is fixedly connected to the end of the triangular support frame 4 away from the mounting base 3. One side of the flipping ring 6 is hinged to the fixing ring 5, and the other side is connected to the fixing ring 5 with a locking device. The fixing ring 5 and the flipping ring 6 merge to form a ring and fit the high-pressure water gun 2. When installing the high-pressure water gun 2 on the triangular support frame 4, the flipping ring 6 is opened, the high-pressure water gun 2 is placed on the fixing ring 5, and then the flipping ring 6 is flipped and clamped onto the outer wall of the high-pressure water gun 2, and locked by the locking device, thus completing the installation and fixation of the high-pressure water gun 2 on the two triangular support frames 4.
[0026] like Figure 1 - Figure 4As shown, the locking member includes a fixed block 7 and a locking block 8, the fixed block 7 is fixedly connected with the fixed ring 5 away from the hinge side, and the locking block 8 is fixedly connected with the turnover ring 6 away from the hinge side.

By installing a plurality of extension springs 11 between the triangular support frame 4 and the cavity 301, when the high-pressure water gun 2 sprays high-speed water flow, the reaction force acts on the high-pressure water gun 2, drives the triangular support frame 4 to move in the opposite direction of the spray, at this time, the rear extension spring 11 is compressed, and the front extension spring 11 is elongated, the plurality of extension springs 11 cooperate with each other, thereby gradually reducing the moving amplitude of the triangular support frame 4, buffering the reaction force received by the high-pressure water gun 2, and reducing the damage of the reaction force of the high-pressure water gun 2 to the practical operation students.
[0028] As shown in Figure 1 - Figure 3 As shown, the end of the cavity 301 away from the triangular support frame 4 is fixedly connected with a plurality of support rods 12, the other ends of the plurality of support rods 12 penetrate the same column of two extension springs 11 and the triangular support frame 4, and are fixedly connected with the other end of the cavity 301, and the two triangular support frames 4 are slidably connected with the plurality of support rods 12.

[0030] As shown in Figure 1 Figure 5 The fixed clamping block 13 and the movable clamping block 14 are both V-shaped structures, and the inner sides of the V-shaped structures are connected with the two side edges of the teaching desk 1.
