Embodiment

Below in conjunction with the drawings and specific embodiments the present invention made further instructions and introduce.

With reference to Fig. 1, Fig. 2, the vertical fire alarm installation of this Novel support mainly by bottom flexible spike 1, tubular body 2, hemisphere 3, bead 4, bracing wire 5, worm gear 9, worm screw 10 etc. form.Described flexible spike 1 is mainly made up of 4 draw-tubes 7, spring 6, stay cord 5, draw-tube 7 is nested in spring 6, one end of spring 6 peaks at draw-tube 7 outermost head, the other end peaks at tubular body 2 outer wall, draw-tube 7 is by being screwed on tubular body 2 outer wall, form symmetry shape all around as shown in Figure 1, the outermost of draw-tube 7 is internally connected with one end of stay cord 5, flexible spike 1 can be realized by spring 6 to shrink along with the size in cotton buttress gap, expand, by reeling of stay cord 5, the active contractive action of draw-tube can be realized.

With reference to Fig. 2, Fig. 3, if described tubular body 2 internal main is made up of stay cord 5, roller 11, termination, draw-tube 7 inner outside is fixed in stay cord 5 one end, the hole of and tubular body 2 and flexible spike 1 junction inner through draw-tube 7, through upper roller 11 along extending bottom roller 11 place, and be fixed on winder, realize the transmission of pulling force on stay cord 5, change sliding friction into rolling friction by roller 11.

With reference to Fig. 2, Fig. 3, a critical function of the present invention is that flexible spike 1 can realize initiatively inwardly shrinking, outwards flick two reciprocal processes, and this function has mainly been coordinated by worm gear 9, worm screw 10, bead 4, stay cord 5, spring 6 etc.Bottom described hemisphere, 3 are mainly made up of worm gear 9, worm screw 10, bead 4, winder 12, built-in lower bottom base 8.Built-in lower bottom base 8 is fixed on 3 inside bottom hemisphere with one heart, worm gear 9 and winder 12 are coaxially fixed on the convex axle on built-in lower bottom base 8, winder 12 rotates along with worm gear 9, winder 12 is connected with the stay cord 5 in 4 horizontal directions, driven the collection of stay cord 5 by the rotation of winder 12, realize pulling open of stay cord 5 by the elastic force of spring 6.Worm screw 10 and bead 4 are coaxially fixed on built-in lower bottom base 8, and worm screw 10 is rotated with bead 4, and worm screw 10 is engaged with worm gear 9, and worm screw 10 is driving link, and worm gear 9 is driven member, and bottom hemisphere, 3 are fixed on the lower edge of tubular body 2 by screw thread rotation.

Using method: step 1: when pulling bead 4, from bottom of device, worm screw 10 is rotated and drives worm gear 9 to rotate clockwise, worm gear 9 drives winder 12 to rotate clockwise, winder 12 rotates collects stay cord 5, stay cord 5 is through upper and lower roller 11, and the elastic force pulling draw-tube 7 to overcome spring 6 shrinks to tubular body 2, and device realizes the shrinkage operation of flexible spike; Step 2: otherwise, when oppositely pulling ball 4, from bottom of device, worm screw 10 drives worm gear 9 counterclockwise to rotation, and worm gear 9 drives winder 12 to be rotated counterclockwise, and stay cord 5 combines the power of self-locking simultaneously by spring 6 power and worm gear 9 worm screw 10, outwards strut along winder 12 surface circle, draw-tube 7 struts laterally by the elastic force effect of spring 6, and what achieve flexible spike 1 struts operation, then device is fixed in the gap of cotton buttress certain limit.To realize the unloading operation of warning device, only need carry out above-mentioned step 1, when flexible spike 1 is retracted to that now flexible friction force between spike 1 and gap wall is less than the power of drop-down bead 4, warning device slowly declines along gap wall.

It should be noted that equivalent replacement done on the basis of the above or substitute and all belong to protection scope of the present invention, protection scope of the present invention is as the criterion with claims.
