DETAILED DESCRIPTION OF THE EMBODIMENTS <L

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 6As shown in the figure, the utility model provides a positioning type fire fighting spray gun, which includes a moving frame 1 and a fire fighting water gun 9. The bottom of the moving frame 1 is provided with moving wheels, which can facilitate personnel to move it to the fire location. Two right-angle seats 2 are fixedly connected to the moving frame 1. The inner wall of each right-angle seat 2 is movably connected with a support frame 10, so that the support frame 10 can be laid down on the moving frame 1 for easy placement to save the placement space. An adjusting frame 4 is slidably arranged in each of the two support frames 10, so that the adjusting frame 4 can slide up and down in the support frame 10. A limiting mechanism for positioning the adjusting frame 4 is arranged between the two support frames 10. Through the limiting mechanism, the fixing of the adjusting frame 4 can be realized to ensure the normal use of the fire fighting water gun 9 by fire fighting personnel. A rotating rod 6 is rotatably connected between the two adjusting frames 4. The middle of the rotating rod 6 is rotatably connected with a rotating cylinder 7. The fire fighting water gun 9 is detachably connected to the rotating cylinder 7. Through the above structure, the fire fighting water gun 9 can be conveniently installed on the rotating cylinder 7, so that the fire fighting water gun 9 can swing horizontally on the rotating cylinder 7 to adjust the angle, and the rotating rod 6 can support the fire fighting water gun 9. There is no need for personnel to hold the fire fighting water gun 9 by hand, and only the spraying angle of the fire fighting water gun 9 needs to be controlled. Moreover, after the fire fighting water gun 9 is installed on the rotating cylinder 7, it can also rotate between the two adjusting frames 4 through the rotating rod 6, so as to realize the up and down swing adjustment of the spraying end of the fire fighting water gun 9, making the use more convenient. When the fire fighting water gun 9 is not in use, the fire fighting water gun 9 can be directly removed from the rotating cylinder 7, then the two adjusting frames 4 are lowered into the support frame 10, and then the support frame 10 is laid down, and the device can be folded and placed, making the placement of the device more flexible. The machinery, parts and equipment in this device all adopt conventional models in the prior art and will not be elaborated here.

[0025] As Figure 1 shown, the bottom ends of the two support frames 10 are respectively hinged in the two right-angle seats 2. A positioning rod 3 corresponding to the two right-angle seats 2 one by one is hinged on the moving frame 1. Through the above structure, the support frame 10 can only swing in the right-angle seat 2, and when the support frame 10 is in a vertical state, it will not continue to swing forward. Then, the positioning rod 3 is abutted against the back of the right-angle seat 2, and the support and limit of the support frame 10 can be completed.

[0026] As Figure 1 and Figure 2 shown, a positioning groove 11 is opened on the back of each support frame 10, and the top end of the positioning rod 3 is inserted into the positioning groove 11. The hinge points at the bottom ends of the two support frames 10 are higher than the hinge points at the bottom ends of the two positioning rods 3. Through the above structure, after the top end of the positioning rod 3 is inserted into the positioning groove 11, the stability of the support frame 10 during use is improved, preventing it from accidentally tipping over. When the support frame 10 is laid down, the positioning rod 3 is swung backward and laid flat, and the support frame 10 can be laid flat backward, so that the support frame 10 is above the positioning rod 3 for easy placement.

[0027] As Figure 1 and Figure 2 shown, the limiting mechanism includes a fixed frame 51, the fixed frame 51 is fixedly connected between two support frames 10, equal-distance arranged clamping grooves 8 are formed on adjacent side surfaces of the two adjustment frames 4, two positioning blocks 55 are slidably arranged in the fixed frame 51, and two positioning plates 53 are fixedly connected thereto. The two positioning blocks 55 are respectively inserted into the corresponding clamping grooves 8. One end of the positioning block 55 is provided with an inclined surface which is downward. Connecting rods 52 are fixedly connected to adjacent side surfaces of the two positioning blocks 55, and the bottom ends of the connecting rods 52 penetrate and extend below the fixed frame 51. The two connecting rods 52 are respectively slid in the two positioning plates 53. Compression springs 54 are sleeved on the surfaces of the two connecting rods 52, and the two ends of the compression springs 54 are respectively fixedly connected to the surfaces of the positioning blocks 55 and the positioning plates 53. With the above structure, it is convenient for personnel to adjust the height of the rotating rod 6. During specific operation, personnel can directly pull the rotating rod 6 upward. At this time, the clamping groove 8 will push the positioning block 55 to slide into the fixed frame 51, and the adjustment frame 4 will not be hindered when moving upward. When the adjustment frame 4 stops moving, the positioning block 55 will automatically position the clamping groove 8 under the elastic force of the compression spring 54 to prevent the adjustment frame 4 from accidentally sliding downward. Only when personnel pull the bottom end of the connecting rod 52 to move, can the positioning block 55 be separated from the adjustment frame 4, that is, the downward adjustment of the adjustment frame 4 is realized.

[0028] As Figure 2 shown, sliding grooves are formed on the mutually remote side surfaces of the two adjustment frames 4. Limit blocks are fixedly connected to the top ends of the two support frames 10, and the limit blocks are located in the sliding grooves. With the above structure, the adjustment frame 4 can be limited in the support frame 10 to prevent the adjustment frame 4 from being pulled out of the support frame 10.

[0029] As Figure 2 shown, both ends of the rotating rod 6 are respectively rotatably connected to the surfaces of the two adjustment frames 4 through damping rotating shafts, and the bottom end of the rotating cylinder 7 is rotatably connected to the middle of the rotating rod 6 through a damping rotating shaft, so that the fire hose nozzle 9 has a positioning effect after swinging.

[0030] As Figure 1 、 Figure 4 and Figure 6As shown in the figure, a mounting block 16 is fixedly connected to the bottom of the fire hose nozzle 9. A limiting groove 15 is formed on the side surface of the mounting block 16, and the mounting block 16 is inserted into the rotating cylinder 7. A plug plate 17 penetrates through the surface of the rotating cylinder 7 and two guide rods 18 are fixedly connected to the surface of the rotating cylinder 7. The plug plate 17 is sleeved on the two guide rods 18, so that the plug plate 17 can slide on the two guide rods 18. One end of the plug plate 17 is inserted into the limiting groove 15. The upper surface of one end of the plug plate 17 is inclined. Tension springs 12 are sleeved on the surfaces of the two guide rods 18, and the two ends of each tension spring 12 are fixedly connected to the surface of the rotating cylinder 7 and the surface of the plug plate 17 respectively. Through the above structure, it is convenient to fix the fire hose nozzle 9 on the rotating cylinder 7 for use. Just insert the mounting block 16 into the rotating cylinder 7. The bottom end of the mounting block 16 will first press the inclined surface on the plug plate 17, so that the plug plate 17 moves forward until the plug plate 17 is inserted into the limiting groove 15, and then the fire hose nozzle 9 can be fixed. When it is necessary to disassemble the fire hose nozzle 9, just pull the plug plate 17 to release the fixation of the fire hose nozzle 9, and the operation is more convenient.

[0031] As Figure 2 and Figure 3 shown in the figure, fixing plates 14 are fixedly connected to both ends of the rotating rod 6. Two opposite limiting plates 13 are fixedly connected to the adjacent side surfaces of the two adjusting frames 4, and the two limiting plates 13 are respectively located above and below the fixing plate 14. Through the above structure, the swing of the rotating rod 6 can be limited, so that the rotating rod 6 can swing between the upper and lower limiting plates 13, and the large-angle flipping of the fire hose nozzle 9 during use can be avoided, which affects the use.

[0032] The working principle and usage process of the present utility model: During use, first move the moving frame 1 to the fire scene, then flip the rotating rod 6 to make the two support frames 10 in a vertical state. Then, position the two positioning rods 3 on the two support frames 10 respectively to prevent the support frames 10 from tipping over. Then, fix the fire hose nozzle 9 in the rotating cylinder 7 through the mounting block 16, and then the positioning use can start. When it is necessary to adjust the height of the fire hose nozzle 9 during use, just pull the rotating rod 6 upward. After the adjustment is completed, the positioning block 55 can automatically limit the adjusting frame 4 under the elastic force of the compression spring 54. When the fire hose nozzle 9 is no longer in use, first pull the plug plate 17 to move to release the fixation of the fire hose nozzle 9, then remove the fire hose nozzle 9 and wind it up for placement, and pull the two connecting rods 52 to move relative to each other to release the positioning of the adjusting frame 4, so that the top end of the adjusting frame 4 slides to the top end of the support frame 10. Then, swing the two positioning rods 3 backward to release the positioning of the support frame 10, and then lay the support frame 10 backward, and the whole can be placed in the storage box, and the operation is more convenient.

[0033] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The content not described in detail in the specification belongs to the prior art well-known to those of ordinary skill in the art.
