Among the figure: 1-cartridge case, 2-housing bottom, 3-spline locking device, 4-screw, 5-spline body, 6-nut, 7-draw-in groove, 8-projection, 9-mounting blocks, 10-connecting ring.
Embodiment
The invention provides a kind of spline locking device 3, now by reference to the accompanying drawings it be further detailed:
Referring to Fig. 1, this spline locking device 3 mainly is comprised of the screw 4 that sets gradually, spline parts and nut 6, wherein the spline parts can stop screw 4 to rotate and with screw 4 clampings; Nut 6 is arranged on the terminal lock screw 4 of screw 4; Whirl-stop device mainly comprises spline body 5 and is arranged on projection 8 and mounting blocks 9 on the spline body 5; Mounting blocks 9 mainly is to be used for fixing spline body 5.When the draw-in groove 7 that is provided with on the screw 4 radially, the center radial position that this projection 8 is arranged on spline body 5 just in time can be stuck in the draw-in groove 7, so that screw 4 passes spline body 5; When on the screw 4 axial draw-in groove 7 being set, this projection 8 is arranged on the outer side wall of spline body 5, just in time is stuck in the draw-in groove 7, also can realize the purpose that stops screw 4 to rotate.In like manner, also the draw-in groove of screw 4 can be replaced to projection, and at the corresponding position of spline body 5 draw-in groove is set, namely be provided with axial projection at screw 4 outer walls; On the spline body 5 of spline parts groove is set, so that projection just in time can be stuck in the groove, and projection is passed spline body 5, nut 6 lockings of screwing on endways; Perhaps can also be at screw 4 radial protrusion to be set, and at the spline body 5 of spline parts adaptive with it radially groove is set, so that projection just in time is stuck in the groove, nut 6 be installed in the end of screw 4, thus lock screw 4.
A kind of aerosol fire-extinguishing device of using above-mentioned spline locking device, referring to Fig. 2, Fig. 3 and Fig. 4, when spline locking device 3 is applied in the aerosol fire-extinguishing device, it can be used for locking the cartridge case 1 of aerosol fire-extinguishing device, the bottom of screw 4 with cartridge case 1 can be connected, can adopt the mode of welding to be fixed on cartridge case 1 bottom and also can pass from inside to outside cartridge case 1 bottom and fix, and radially offer draw-in groove 7 so that engage with projection 8 at it; Offer the screw corresponding with screw 4 and mounting blocks 9 structures of the shape of this screw and spline body 5 are suitable at housing bottom 2 of the present invention, can get final product so that spline body 5 just in time can embed in the screw of housing bottom 2 and can not rotate by mounting blocks 9, also mounting blocks 9 can be set, the structure that directly spline body 5 and housing bottom is fixed with one perhaps can also be with projection 8 simultaneously and housing bottom and the screw 4 clampings location that can realize spline body 5.Of the present invention protruding 8 are arranged on the spline body 5 and can embed in the draw-in groove 7 of screw 4, and screw 4 passes spline body 5, the screw that extends to housing bottom 2 is outside, the nut 6 of screwing on can be finished assembling, and the screw by housing bottom 2 when fastening nut 6 blocks spline body 5, limits its rotation, and the projection 8 in the draw-in groove 7 of embedding screw 4 is by 5 restrictions of spline body, also can not rotate and namely can limit screw 4 and rotate, fastening nut 6 is just finished the fixing of cartridge case 1 and housing.When the hole that screw 4 passes cartridge case 1 bottom extends to cartridge case 1 when outer, can a snap ring be set screw 4 necks outside cartridge case 1, so that it can tighten screw 4, the axial freedom of restriction screw 4.
When spline locking device 3 of the present invention is used in aerosol fire-extinguishing device, when running into combined fixed fire-fighting equipment, it can be provided with a plurality of cartridge cases 1 in housing, then can a plurality of spline locking devices 3 be linked together by connecting ring 10, form one, also can strengthen its whole structural strength, its number is corresponding with the number of cartridge case 1 also can be according to actual use condition adjustment.
Above-mentioned spline locking device 3 can adopt plastic material or the rubber material with certain structural strength and opposing stress.
It is fixing that spline locking device 3 of the present invention not only is applied in the cartridge case 1 of aerosol fire-extinguishing device, also can be applied in needing screw 4 to lock but can't realizing the occasion that nut 6 is fastening of other.
