Embodiment Construction
[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] A fire sprinkler suitable for fire fighting equipment is composed of a base 1, a ball head 2, a swing structure and a limit structure; the limit structure includes a first limit structure and a second limit structure.
[0030] Taking the horizontal transverse direction as the reference direction, one end of the base 1 is fixed with the fire fighting equipment, and the other end is an open ball groove 7; the ball head 2 is placed in the ball groove 7, and is limited by the curved edge of the outer end of the ball groove 7; preferably , the outer end of the ball groove 7 skips the center of the ball groove 7 along the horizontal transverse direction, and a snap ring 10 whose longitudinal cross-sectional diameter is smaller than the diameter of the ball head 2 is arranged at the port. The curved edge or the snap ring 10 constitutes the firs...

The invention discloses a fire-fighting sprayer suitable for fire-fighting equipment. The fire-fighting sprayer comprises a base, a ball groove is formed in the end of the base in the horizontal direction. Through the curvature of the ball groove, the ball head is embedded in the ball groove, and a clamping ring with the diameter smaller than that of the ball head is arranged at an end opening of the ball groove. A spraying channel of which the inner side end is connected with a fire-fighting agent spraying pipe in the fire-fighting equipment is arranged in the ball head, and a nozzle of the spraying channel is arranged at the outer side end of the ball head; the inertia ring is arranged along the outer side wall of the ball head. The swingable spray head enables the sprayed fire-fighting agent to cover a certain area in front; the swing amplitude of the ball head is adjusted through the limiting ring capable of rotating along the limiting groove, and then the coverage area of the fire extinguishing agent is adjusted; the inertia ring provides inertia for swinging of the ball head and is matched with the limiting ring to limit the swinging amplitude of the ball head; part of power is provided for swinging of the ball head through linkage of the elastic pipe. The device is simple in structure and convenient to use, is particularly suitable for miniature or fixed fire-fighting equipment which is stimulated by an external heat source to be automatically started, and has very high practicability and wide applicability.
Description
technical field [0001] The invention relates to a fire-fighting nozzle, in particular to a fire-fighting nozzle suitable for fire-fighting equipment. Background technique [0002] Most of the nozzles of the existing fire fighting equipment adopt the duckbill type, which is suitable for large-dose outdoor spraying on a large area, and the effect is particularly obvious. [0003] The duckbill nozzle has the advantages of larger volume and larger spray dose, and it is not suitable for small fire equipment to be used in small spaces. [0004] Therefore, there is a need for a new fire sprinkler suitable for fire fighting equipment. SUMMARY OF THE INVENTION [0005] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a fire-fighting nozzle suitable for fire-fighting equipment. [0006] In order to achieve above-mentioned goal, the present invention adopts following technical scheme: [0007] A fire sprinkler suitable for fir...
