Description of drawings
To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment 1,2;
Fig. 2 is the structural representation of the utility model embodiment 1,2;
Fig. 3 is the structural representation of the utility model embodiment 2;
Fig. 4 is the structural representation of the another kind of embodiment of the utility model embodiment 2.
The specific embodiment
As shown in Figure 1, the purpose that cover body 1 sidewall has UNICOM's mouth 2 also is to make cover body 1 inner chamber and extraneous UNICOM to keep cover body 1 interior fire-fighting temperature-sensitive glass probe after external environment changes, can in time move, and starts fire-fighting system.
Because fire-fighting temperature-sensitive glass probe is mounted on the extinguishing pipe; Therefore the cover body 1 of protective cover detachably is fixed on the extinguishing pipe; Connector through being provided with in cover body 1 bottom surface is detachably fixing; In the present embodiment, connector is exactly the buckling groove 3 that is used to tighten extinguishing pipe that on cover body 1 bottom surface open end, has.Said buckling groove 3 is corresponding with extinguishing pipe respectively to be provided with one in said cover body 1 both sides.Connector can also be selected clip, hold out against multiple structures such as screw.
In order to give the protection fully of fire-fighting temperature-sensitive glass probe; Cover body 1 collision impact to external world will have corresponding absorption; Then said cover body 1 highly is higher than the height of fire-fighting temperature-sensitive glass probe, and cover body 1 end face inwall, inwall all and between the fire-fighting temperature-sensitive glass probe leaves the gap all around.Prevent that extraneous collision impact from passing to fire-fighting temperature-sensitive glass probe.
As shown in Figure 1, it is the UNICOM that keeps fire-fighting temperature-sensitive glass probe and external environment that UNICOM's mouth 2 of cover body 1 is provided with purpose, occurs in external environment under the situation such as fire, high temperature, in time the action launching fire-fighting system.UNICOM's mouth 2 can be arranged on the optional position of cover body 1, preferably is arranged on cover body 1 sidewall at the UNICOM's mouth that is provided with on the cover body 12 corresponding fire-fighting temperature-sensitive glass probes.Can't avoid article or foreign material from dropping in the air because the top is provided with UNICOM's mouth 2, therefore, UNICOM's mouth 2 is arranged on more effectively protect fire-fighting temperature-sensitive glass probe on cover body 1 sidewall through UNICOM's mouth 2 hit fire-fighting temperature-sensitive glass probes.UNICOM's mouth 2 is difficult for excessive or too small with respect to cover body 1, excessive just can not the probe to fire-fighting temperature-sensitive glass play a protective role, and the too small fire-fighting temperature-sensitive glass that is unfavorable for is popped one's head in time corresponding; Therefore; The bore of UNICOM's mouth 2 is preferably 1.2～1.5cm, and the shape of UNICOM's mouth 2 does not limit, and Any shape can; On cover body 1 sidewall, be symmetrical set two UNICOM's mouths 2 in the utility model, UNICOM's mouth 2 is circle or rectangle.
For cover body 1 is not popped one's head in the stressed fire-fighting temperature-sensitive glass that passes in outside; Then leave the gap between fire-fighting temperature-sensitive glass probe and the cover body 1; Especially leave spacing between cover body 1 end face inwall and the fire-fighting temperature-sensitive glass probe, prevent that article from dropping to pound on cover body 1 impulsive force is passed to fire-fighting temperature-sensitive glass probe.Cover body 1 shape does not limit, and the shape of bottom surface opening can arbitrarily.
During installation, fire-fighting temperature-sensitive glass probe can be fixed on the extinguishing pipe 5 according to original mode, and cover body 1 detachably is fixed on the extinguishing pipe 5.
Because fire-fighting temperature-sensitive glass probe is mounted on the extinguishing pipe 5; Therefore the cover body 1 of protective cover need detachably be fixed on the extinguishing pipe 5; Connector through being provided with in cover body 1 bottom surface is detachably fixing; Detachable fixing mode has multiple: a kind of connector is on the outer wall of cover body 1 lower end or end face, clip to be set, and the clip both sides are fastened on the extinguishing pipe 5 clip just that cover body 1 is fixing through screw.
The second way is that the cover body 1 with protective cover directly is connected on the extinguishing pipe 5; Because fire-fighting temperature-sensitive glass probe is installed on the extinguishing pipe 5, is provided with the connector that is connected on the extinguishing pipe 5 in cover body 1 bottom surface, and is as shown in Figure 3; Generally correspondence is provided with two fins 4 on corresponding extinguishing pipe 5; Fin 4 lays respectively at fire-fighting temperature-sensitive glass probe both sides, and then a kind of mode of clamping is: corresponding these two fins 4, and connector is exactly like Fig. 1, the buckling groove 3 that is used to tighten extinguishing pipe 5 that on cover body 1 bottom surface open end, has shown in 2; Buckling groove 3 is installed on the fin 4, and said buckling groove 3 and extinguishing pipe 5 are corresponding respectively to be provided with one in cover body 1 both sides.
Like Fig. 1,2, shown in 4, the another kind of mode of clamping is that the cover body 1 bottom surface openend of protective cover has the buckling groove 3 as connector, and buckling groove 3 directly is connected on the outer wall of extinguishing pipe 5.Need cover body be made greatlyyer in this mode, satisfy and directly to be connected on the extinguishing pipe 5.
Because buckling groove 3 is directly to be connected on the extinguishing pipe 5, therefore want cover body 1 chucking, the inwall width of then said buckling groove 3 satisfies: buckling groove 3 is interference fitted on the extinguishing pipe 5.Be connected to 4 last times of fin, buckling groove 3 inwalls and fin 4 external diameter interference fit directly are connected to extinguishing pipe 5 last times, buckling groove 3 inwalls and extinguishing pipe 5 outer wall interference fit at cover body 1.
The UNICOM's mouth 2 that is provided with on the cover body 1 can make and occur passing through UNICOM's mouth 2 timely action launching fire-fighting systems under the situation such as fire, high temperature in external environment.UNICOM's mouth 2 can be arranged on the optional position of cover body 1; Preferably be arranged on cover body 1 sidewall at the UNICOM's mouth that is provided with on the cover body 12 corresponding fire-fighting temperature-sensitive glass probes; The shape of UNICOM's mouth 2 does not limit; Any shape can, on cover body 1 sidewall, be symmetrical set two UNICOM's mouths 2 in the utility model, UNICOM's mouth 2 adopts circular or rectangular shapes.
