Specific embodiment
A kind of linkage fire-fighting spraying head, as shown in Figure 1, illustrating by taking three spray heads as an example, but is not limited to three, as long as
It is the linkage structure that the utility model can be used in two or more spray heads.It is specifically described by taking intermediate spray head as an example:
It from top to bottom successively include pipe fitting 1, the upper yoke cantilever crane of 1 bottom end integrally connected of pipe fitting, with upper yoke cantilever crane bottom end integrally connected
Casing 3, be radially fixed at the upper splash box 10 on 3 top of casing, the U-shaped structure with 3 bottom end integrally connected of casing
Lower yoke arm frame 4, the nozzle boss 5 being fixedly connected with the gathering bottom end of the U-shaped structure of lower yoke arm frame 4 and be fixed at nozzle boss
The lower splash box 6 of 5 bottom ends.3 inner sleeve of casing cylindrical trussed shore 7；Upper yoke cantilever crane includes two connecting plates 21, connecting plate 21
Top and pipe fitting 1 bottom end integrally connected, the top integrally connected of the bottom end of connecting plate 21 and casing 3；In upper yoke cantilever crane
It is provided with support rod 8,8 apical grafting of support rod is between pipe fitting 1 and trussed shore 7；Vitreum 9, glass are provided in lower yoke arm frame 4
The top of body 9 is fixedly connected with trussed shore 7, and bottom end is connected on nozzle boss 5；It is high filled with thermal expansion coefficient in vitreum 9
Organic solution.
As shown in Figure 1, the realization of linkage triggering is caused in casing 3 to lower landing by trussed shore 7, specific structure
Are as follows: the top of the trussed shore 7 of intermediate spray head is fixedly connected with the second traction steel wire 11, the other end of the second traction steel wire 11 with
The bottom of the support rod 8 of right side spray head is fixedly connected；The bottom of the support rod 8 of intermediate spray head is fixedly connected with the first traction
The top of steel wire 12, the trussed shore 7 of the other end and left side spray head of the first traction steel wire 12 is fixedly connected.Left side spray head
The bottom of support rod 8 is equally fixedly connected with the first traction steel wire 12, and the other end of first traction steel wire 12 is fixedly connected on
In addition the top of the trussed shore 7 of the spray head adjacent with left side spray head；Equally, the top of the trussed shore 7 of right side spray head is solid
Surely the second traction steel wire 11, the support rod of the other end of the second traction steel wire 11 spray head adjacent with right side spray head are connected with
8 bottom is fixedly connected；It so repeats, realizes the linkage triggering control between each spray head.
As shown in Fig. 2, the bottom of pipe fitting 1 offers apopore 13, blocking in apopore 13 has sealing element 14；Support rod
8 top abuts the bottom end of sealing element 14, and the bottom end of support rod 8 abuts trussed shore 7.Since support rod 8 is only that apical grafting is sealing
Between part 14 and trussed shore 7, in order to further ensure the stability of support rod 8, the second limit is provided in the bottom surface of sealing element 14
Position slot 15 makes the top of support rod 8 match limit and is connected in the second limiting slot 15；As shown in figure 3, in the top surface of trussed shore 7
It is provided with the first limiting slot 16, the bottom end matching limit of support rod 8 is connected in the first limiting slot 16.
As shown in Figure 4 and Figure 5, nozzle boss 5 is tube-shaped structure, and internal screw thread is equipped with screw 17；Screw 17 is through spray
The top of headstock 5, screw 17 is abutted with the bottom end of vitreum 9, and the bottom end of screw 17 is inside the round tube of nozzle boss 5；By twisting
The bottom end of dynamic screw 17 guarantees that the stabilization of vitreum 9 is supported between trussed shore 7 and nozzle boss 5.
The fire-fighting spraying head of the utility model, linkage control principle are specific as follows:
As shown in Figure 1, when the high organic solution of the thermal expansion coefficient filled in the vitreum 9 of intermediate spray head is heated continuous
Expansion, after vitreum 9 is burst, support of the trussed shore 7 without bottom and to lower landing in casing 3, drive support rod 8 to downslide
It falling, sealing element 14 is taken off after losing support by water flow punching, and water is sprayed from apopore 13, after upper splash box 10 and lower splash box 6,
It is sprayed to the scene of fire of lower section.In 7 slide downward of trussed shore of intermediate spray head, the second traction steel of the connection of trussed shore 7
Silk 11 falls downwards, pulls the support rod 8 of the spray head on right side, and the support rod 8 is made to deviate original position, the spray head spray of triggering right side
Leaching.Similarly, the trussed shore 7 of left side spray head is also pulled and drops, to trigger the spray head spray in left side.
Since intermediate spray head is heated triggering, the vitreum 9 that trussed shore 7 loses bottom supports, can just cause
The spray head of the left and right sides.If the spray head being triggered, i.e., the spray head of unmanaged triggering, i.e. vitreum 9 do not damage, still for
Trussed shore 7 provides support, therefore trussed shore 7 will not fall or slide downwards, to will not cause spray head adjacent thereto
Triggering, it is possible to prevente effectively from accidentally spraying.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
