Anti-vibration fire-fighting lance

Abstract

The utility model provides an anti-vibration fire-fighting lance, and aims to solve the technical problem that a fireman needs to control the vibration of the fire-fighting lance with great strength due to the fact that high-pressure water in the fire-fighting lance has strong impact force on the fireman. The fire-fighting lance comprises: a lance main body, one end of which is connected with a fire hose and the other end of which is a water outlet; the water gun main body is sleeved with the spring, and one end of the spring is close to the water outlet; the supporting frame is movably arranged on the water gun body, and one end of the supporting frame abuts against the other end of the spring; the two handles are symmetrically arranged on the two sides of the supporting frame. During use, a firefighter holds the handle, one end of the water gun main body is connected to a fire hose, and when water pressure in the water gun main body is increased to cause vibration of the water gun main body, the spring arranged on the water gun main body can relieve impact force borne by the hands of the firefighter, so that the risk that the fire-fighting water gun falls off from the hands of the firefighter is reduced.

[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Example:

[0031] See also Figure 1-Figure 3 A vibration-resistant fire-fighting water gun comprises a water gun body 1, a spring 2, a support frame 3 and a handle 4, wherein the water gun body 1 is a rotating body structure, one end of the water gun body 1 is a water outlet, and the other end can be connected to a fire hose.

[0032] A spring 2 is sleeved on the water gun body 1, and one end of the spring 2 is fixed on the end of the water gun body 1 close to the water outlet. The support frame 3 is an annular structure, and the support frame 3 is also sleeved on the water gun body 1.

[0033] The end of the spring 2 away from the water outlet is fixedly arranged on the support frame 3, and the support frame 3 is in a movable state on the water gun body 1.

[0034] A handle 4 is provided on each side of the support frame 3 .

[0035] The working principle of this embodiment is that the firefighter holds the handle 4, and one end of the water gun body 1 is connected to the fire hose. When the water pressure in the water gun body 1 increases, the water gun body 1 vibrates. At this time, the spring 2 arranged on the water gun body 1 can alleviate the impact force on the firefighter's hand, thereby reducing the risk of the fire hose falling off the firefighter's hand.

[0036] In one specific embodiment:

[0037] An annular connecting ring 5 is sleeved on one end of the water gun body 1 close to the water outlet. The connecting ring 5 is fixedly arranged on the water gun body 1 so that the end of the spring 2 can be fixedly arranged on the connecting ring 5, thereby strengthening the strength of the connection between the spring 2 and the water gun body 1.

[0038] In another specific embodiment:

[0039] Two support frames 3 are arranged on the water gun body 1, and the two support frames 3 are both slidably arranged on the water gun body 1. At the same time, two connecting rods 6 are arranged between the two support frames 3, and the two ends of the connecting rod 6 are respectively fixedly connected to the two support frames 3, and the two handles 4 are respectively arranged on the two connecting rods 6.

[0040] In this embodiment, two support frames 3 and two connecting rods 6 are provided to enhance the stability of the support frame 3 on the water gun body 1 and avoid jamming.

[0041] In another specific embodiment:

[0042] The handle 4 is a U-shaped structure, and the two ends of the handle 4 are fixedly connected to the two ends of the connecting rod 6 respectively, and form a U-shaped structure with the connecting rod 6.

[0043] A through hole is provided at one end of the connecting rod 6, and a positioning rod 7 is slidably provided in the through hole. The end of the positioning rod 7 can contact the outer wall surface of the water gun body 1, and the length direction of the positioning rod 7 is perpendicular to the length direction of the water gun body 1.

[0044] A pressure rod 8 is rotatably provided on the inner side of the handle 4 , the middle part of the pressure rod 8 is rotatably connected to the handle 4 , and one end of the pressure rod 8 is in contact with the other end of the positioning rod 7 .

[0045] In this embodiment, when using the fire hose, the firefighter can squeeze the pressure rod 8 so that the end of the positioning rod 7 is pressed against the outer wall of the hose body 1, so that the handle 4 and the hose body 1 are integrated, thereby facilitating the firefighter to accurately control the spraying position of the water in the fire hose.

[0046] In addition, a support rod 9 is rotatably provided in the handle 4 , and the end of the support rod 9 can abut against the end of the pressure rod 8 away from the positioning rod.

[0047] Preferably, positioning rods, pressure rods 8 and support rods 9 are symmetrically arranged on the two handles 4 .

[0048] By setting the support rod 9, the pressure rod 8 can be kept in a state of pressing the positioning rod 7, reducing the workload of the firefighter's hands. By symmetrically setting the positioning rod, pressure rod 8 and support rod 9 on the two handles 4, the stability of the handles 4 when connected to the water gun body 1 can be improved.

[0049] In another specific embodiment:

[0050] The outer wall of the water gun body 1 is provided with a limit rod 10, and the support frame 3 is provided with a limit groove matching the limit rod 10. By setting the limit groove and the limit rod 10, the movable direction of the water gun body 1 in the support frame 3 is limited.

[0051] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
