[0002] With the continuous development of fire-fighting technology, fire sprinklers are an important part of the fire-fighting system. Their performance and ease of use are of great significance to ensuring the safety of personnel and property. Existing handheld fire sprinklers are mostly conical structures, which are connected to fire hoses through coupling components. Although this structure can increase the impact force of the water spray, it also brings some problems. First, a large reaction force will be generated when the water flows through the sprinkler, which makes the sprinkler easy to shake or shift during the water spraying process, which increases the difficulty of adjusting the spraying direction of the sprinkler. Secondly, when adjusting the direction of the sprinkler, the operator needs to exert force for a long time, and the hand muscles are prone to fatigue, and even cause soreness and numbness. This not only reduces the operating efficiency, but also may cause accidents due to the sprinkler falling out of hand.

[0019] The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example 1

[0020] Please refer to the attached Figure 1-4, this embodiment is a fire sprinkler fixing device: it includes a support seat 1, the support seat 1 is rotatably connected to a support platform 2, the support platform 2 is hinged with a handrail frame, the handrail frame includes a control part and a sprinkler fixing part, the control part includes two symmetrically distributed control rods 3, the two control rods 3 are hinged to the support platform 2, the sprinkler fixing part includes a collar 4 and a fixing screw 5, the collar 4 is fixedly installed between the two control rods 3, and the fixing screw 5 is threadedly connected to the side of the collar 4.

[0021] The support platform 2 is rotatably installed on the support base 1, and the support platform 2 can rotate 360 ​​degrees relative to the support base 1. The handrail frame can be adjusted in the upper and lower angles by being hinged with the support platform 2. The fire sprinkler is fixed in the sprinkler fixing part of the handrail frame. The fire sprinkler can be changed in any azimuth angle within the spatial range through the rotation of the support platform 2 and the handrail frame, thereby improving the flexibility of the device. There are two control levers 3, and the two control levers 3 are symmetrical about the center of the support platform 2. Both control levers 3 are sideways Z-shaped structures. One section of the control lever 3 is hinged on the support platform 2, and the other end of the control lever 3 is bent upward. When in use, both hands are placed on the two control levers 3 respectively, and the control levers 3 are lifted. Pull the operating lever 3 to rotate it along the hinge axis. The rotation of the operating lever 3 drives the fire sprinkler to swing up and down, so that the operating lever 3 drives the fire sprinkler to change its angle. There are two replacement rings 4 for fixing the fire sprinkler. The fire sprinkler is a conical structure. The ring 4 on the front side is smaller than the ring 4 on the rear side. When fixing the fire sprinkler, move the fire sprinkler through the through hole of the ring 4 with a thickness forward. After the front end of the fire sprinkler passes through the through hole of the ring 4 at the front end, rotate the fixing screw 5 on the side to tighten the fire sprinkler on the inside of the ring 4 through the fixing screw 5 to prevent the reaction of the fire sprinkler from driving the fire sprinkler to detach from the ring 4, thereby ensuring the firmness of the fixing of the ring 4.

[0022] One end of the control rod 3 is fixedly connected to a connecting block 6, and the connecting block 6 is rotatably connected to the support platform 2. The other end of the control rod is hinged with a connecting rod 7, and the other end of the connecting rod 7 is hinged with a sliding sleeve 8, and the sliding sleeve 8 is slidably connected to the support platform 2; one end of the control rod 3 is hinged on the support platform 2 through the connecting block 6, and the other end of the control rod 3 is slidably connected to the support platform 2 through the connecting rod and the sliding sleeve 8. With the sliding platform as the base, the control rod 3, the connecting rod 7 and the sliding sleeve 8 constitute a crank slider mechanism. The connecting rod 7 and the sliding sleeve 8 can improve the stability of the control rod 3 after rotation, and avoid the instability of the single hinge mode of the control rod 3 during use. Furthermore, bolts can be installed on the outside of the sliding sleeve 8, and the sliding sleeve 8 and the guide rod 10 are fixed by bolts. When it is necessary to spray a single point, the difficulty of controlling the control rod 3 is reduced.

[0023] The bottom of the collar 4 is fixedly connected with a support rod 9, and the two ends of the support rod 9 are fixedly connected to the two control rods 3; the support rod 9 is horizontally connected between the two control rods 3. The support rod 9 not only supports the collar 4, but also connects the two control rods 3 into a whole to ensure the synchronous movement of the two control rods 3.

[0024] The support platform 2 is an annular structure, and a guide rod 10 is fixedly connected to the support platform 2 and is slidably connected to the sliding sleeve 8. A hydraulic telescopic rod 11 is provided between the support seat 1 and the support platform 2; the support platform 2 is a circular ring structure, and the shape of the support platform 2 is similar to a steering wheel, which is convenient for the user to control the support platform 2 when rotating. The hydraulic telescopic rod 11 between the base and the support platform 2 can adjust the height of the support platform 2, thereby increasing the height of the spray during actual use. At the same time, adjusting to a suitable height for users of different heights can reduce fatigue during use and improve the user experience. Example 2

[0025] The structure is the same as the above embodiment. Figure 5 As shown, the specific difference of this embodiment is that: a cushion block 12 is provided at the edge of the support platform 2, and both ends of the cushion block 12 are fixedly connected with fixing belts 13, and the two fixing belts 13 are fixedly connected with buckles 14 that are clamped to each other.

[0026] The pad 12 is located directly behind the armrest, and the outer side of the pad 12 is an arc-shaped structure. When the user's two hands are on the joystick 3, the user's abdomen contacts the support platform 2, and the pad 12 increases the softness during contact. The fixing belts 13 and buckles 14 on both sides of the pad 12 can pass around the user's body and be tied to the body. When the user's body rotates, the support platform 2 is driven to rotate, thereby improving the flexibility of the overall device as the user moves.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
