Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
Referring to figs. 1 to shown in Fig. 5, a kind of reusable formula fire-fighting spraying head, including spray head 1, splash box 2, support base 3,
Slide bar 4, thermally conductive sheet 5, power-assisted component 6.
Spray head 1 is equipped with nozzle 11, and the water blockoff head 21 cooperated with nozzle 11 is equipped with above splash box 2, and water blockoff head 21 is upper
Narrow lower wide type, 21 upper end of water blockoff head be equipped with can valve nozzles rubber block 22.
Support base 3 is fixed on spray head 1, and support base 3, which is equipped with, accommodates the perforation 31 that slide bar 4 passes through, slide bar 4 one
End connection splash box 2, the other end are equipped with limiting section 41, and the maximum cross-section length of limiting section 32 is greater than perforation 31 on support base 3
Aperture, and then limiting section 41 can not be passed through from perforation 31,31 tops of perforation are equipped with locating slot 32,4 middle section of slide bar is equipped with location hole
42, positioning pin 43 is installed in location hole 42, positioning pin 43 is made of fusible alloy, and positioning pin 43 is installed on location hole 42 and blocks
When terminating in locating slot 32, the water blockoff head 21 of splash box 2 is in the state of valve nozzles 11, and thermally conductive sheet 5 is equipped with 2 lower section of splash box simultaneously
It is fixedly connected with splash box 2, by screw 51 and slide bar 4, removably locking connects thermally conductive sheet 5, slide bar 4, perforation 31, positioning
Pin 43 is equipped with multiple, and thermally conductive sheet 5 is connect with each slide bar 4, and slide bar 4, thermally conductive sheet 5 are copper at and then heat can pass through thermally conductive sheet
5, slide bar 4, which synchronizes, is transmitted at a positioning pin 43.
Power-assisted component 6 includes stressed plate 61, power assistant spring 62, guiding bar 63, and stressed plate 61 is fixed on limiting section 41
Side, power assistant spring 62 are set between stressed plate 61 and limiting section 41, and power assistant spring 62 provides slide bar 4 and splash box 2 is driven to decline
Thrust, guiding bar 63 are fixed on stressed plate 61, and guiding bar 63 and slide bar 4 are coaxially disposed, and power assistant spring 62 is sheathed on guidance
On bar 63, guiding bar 63 guides power assistant spring 62 to pop up towards 41 direction of limiting section, avoids 62 sideslip of power assistant spring.
This kind of reusable formula fire-fighting spraying head working principle is as follows, (such as Fig. 1 institute when which is in close state
Show), positioning pin 43 is installed in the location hole 42 of slide bar 4, since positioning pin 43 can not pass through the perforation 31 of support base 3, in turn
Slide bar 4 can not slide and be located on support base 3, at this point, positioning pin 43 is locked in locating slot 32, splash box 2 and slide bar 4
Connection, when slide bar 4 is in the locking position, the water blockoff head 21 on splash box 2 blocks nozzle 11, and since water blockoff head 21 pushes up
Portion is rubber block 22, ensure that the reliable closure of nozzle 11；When meeting with fire behavior (as shown in Figure 4), it is located at 2 bottom of splash box
Thermally conductive sheet 5 it is heated first, since thermally conductive sheet 5 and each slide bar 4 are all connected with, and then heat passes through each slide bar 4 and is transferred to positioning pin
At 43, since positioning pin 43 is fusible alloy, when reaching the fusing point of fusible alloy, positioning pin is melted, after positioning pin fusing,
Slide bar loses the positioning action of positioning pin, in nozzle under the collective effect of hydraulic pressure and power assistant spring elastic force, slide bar, splash box
It drops to limiting section to reach at support base, since limiting section section maximum length is greater than the penetration hole diameter of support base, and then limit
Portion can not pass through perforation, and slide bar is positioned again, and nozzle is opened at this time, and water is sprayed by nozzle, and water is dissipated in the punishment of water blockoff head
And disperse again on splash box, water disperses around ejection；The effect of power assistant spring is that providing an initial thrust drives
Slide bar decline, when nozzle being avoided to be blocked completely, the hydraulic pressure in spray head is not enough to wash open water blockoff head, and guiding bar is coaxial with slide bar
Setting guarantees to avoid sideslip towards limiting section when power assistant spring pops up；After fire behavior, by way of replacing positioning pin
It can restore the working condition of the fire-fighting spraying head, it can be achieved that being used for multiple times；Splash box is fixedly connected with thermally conductive sheet, thermally conductive sheet and cunning
Bar is detachably connected by screw, and thermally conductive sheet and splash box are dismantled, reinstall positioning pin, then lock thermally conductive sheet and splashing
Disk can carry out recovery operation to the fire-fighting spraying head, simple and convenient.
It above are only a kind of specific embodiment of the utility model, but the design concept of the utility model is not limited to
This, all non-essential modifications to the present invention made by this concept should belong to infringement scope of protection of the utility model
Behavior.
