Description
Technical field
The utility model relates to a kind of hand-operated curtain screen-roller safety guard.
Background technology
Existing hand-operated curtain screen-roller in use, through pulling pull cord, bead directly drives the pearl dish and does rotation, and roller shutter cloth is launched or rolling-in.Generally speaking, roller shutter cloth is after expansion or rolling-in, and pull cord vertically is suspended on the windowsill limit under the effect of gravity.Under wind-force or artificial action, can swing, can produce potential safety hazard.If children are rich to neck pull cord because of carelessness under the ordering about of curiosity, asphyxiant danger is arranged.
Existing manually moving curtain screen-roller is not when installing, if the people is for going pull cord, bead can drive the pearl dish and rotate, and bead also can be done do action, and this also causes children's curiosity easily, holds easily when toy and plays, and also has potential safety hazard in this case.Therefore, existing curtain roller shutter structure exists hidden danger concerning the client.
The utility model content
The utility model technical problem to be solved be to above-mentioned prior art provide a kind of screen-roller do not install and installation situation under, have safety protection function, avoided the dangerous hand-operated curtain screen-roller safety guard that possibly meet accident.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this hand-operated curtain screen-roller safety guard is characterized in that: comprise
Mount pad has the through hole that can the bead of hand-operated curtain screen-roller be penetrated on this mount pad, also be provided with the groove that is communicated with said through hole on this mount pad;
Slide block is slidingly arranged in the groove of said mount pad, and this slide block has an arch contact site, and under the nature, thereby the inner face of the arch contact site of this slide block has the locking state that is against in the through hole on the bead locking bead between two pearls;
Elastic component; First end and said slide block offset; The groove inwall of second end and said mount pad offsets, thereby this elastic component has all the time and slide block is pushed away the mount pad groove makes the inner face of the arch contact site of slide block prop up in the through hole on the bead trend between two pearls.
Said slide block comprises that the left and right sides is the location division and the middle interconnecting piece that is down " U " font that is connected location division, the left and right sides of " mountain " font, said being down the middle interconnecting piece of " U " font be the arch contact site of said slide block.
Said elastic component is a spring, is installed on the intermediate studdle of said location division.
Be provided with in the groove of said mount pad and be used for slide block is fixed on the reference column in the said mount pad groove; The two ends of this reference column and mount pad groove inwall offset; This reference column is installed in the arch contact site inboard of said slide block, is used to make said slide block to be unlikely to break away from said mount pad.
Compared with prior art, the advantage of the utility model is: after using the safety guard that this practical sexual type provides, when device for opening and closing curtain is not installed; Bead is in locking state, and bead can not shuttling movement under the pulling of external force; Avoided children to make the possibility of its motion because of curiosity pulling bead; And under installation situation, the lower end of bead is fixed on the positioning seat, makes the bead can only be at the artificial action lower swing; Prevent children should be curious and easily bead rich to the neck maybe, also avoided dangerous generation.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Hand-operated curtain screen-roller safety guard shown in Fig. 1～4, it comprises
Integral body is the mount pad 1 of arch; Has the through hole 11 that can the bead 2 of hand-operated curtain screen-roller be penetrated on this mount pad 1; Also be provided with the groove 12 that is communicated with said through hole 11 on this mount pad 1, also be provided with on this mount pad 1 and be used for this mount pad is fixed on the installing hole 13 on the windowsill 3;
Slide block 4; Be slidingly arranged in the groove 12 of said mount pad 1; Slide block 4 comprises that the left and right sides is the location division 41,42 and the middle interconnecting piece 43 that is down " U " font that is connected location division, the left and right sides 41,42 of " mountain " font; This middle interconnecting piece 43 that is down " U " font is the arch contact site of slide block 4, under the nature, locks bead 2 between two pearls thereby the inner face 431 of the arch contact site 43 of this slide block 4 is against in the through hole on the bead 2;
Be provided with reference column 5 in the groove 12 of mount pad 1; The two ends of this reference column 5 and mount pad 1 groove 12 inwalls offset; This reference column 5 is installed in arch contact site 43 inboards of said slide block 4, and is riveted in the mount pad 1 through rivet 6, is used to make said slide block 4 to be unlikely to break away from said mount pad 1;
Two springs 7; Two springs 7 are set in respectively on the interfix post 411,421 of location division, the slide block left and right sides 41,42; And groove 12 inwalls of end and said mount pad 1 offset, thereby two springs 7 have all the time and slide block 4 is pushed away the mount pad groove make the inner face of the arch contact site 43 of slide block 4 prop up in the through hole on the bead 2 trend between two pearls.
During use; Earlier bead 2 is packed in the through hole 11 of mount pad 1; Two springs 7 are inserted in the interfix post 411,421 of slide block 4; Then the location division, the left and right sides of slide block 4 is inserted into the bottom along groove 12 sidewalls of mount pad 1, puts into mount pad 1 to reference column 5 again, (aliging with the reference column hole in the mount pad hole) is riveted on reference column 5 on the mount pad 1 with rivet 6 again.Under installation situation not; Elastic force through two springs 7; The inner face of the arch contact site 43 of slide block 4 props up in the through hole on the bead 2 rope between two pearls, thereby is fixed on bead 2 between the face of cylinder of inner face and reference column 5 of arch contact site 43 of slide block 4, and it can not be moved; Bead is stretchy not, and bead is in locking state.
After the hand-operated curtain screen-roller is installed on the window; Be fixed on 4 last times of windowsill to mount pad 1 through two cross recess self tapping pan head screws 8, thereby slide block 4 is extruded to mount pad is inner and moves, at this moment slide block 4 is in the return state; The inner face of the arch contact site 43 of slide block 4 no longer props up in the through hole on the bead 2 rope between two pearls; Bead 2 is in free state, and pulling bead 2 moves freely its through hole 11 the insides at mount pad 1, roller shutter is accomplished launched or the rolling-in action.
After curtain assembled, the lower end of bead 2 was fixed on the positioning seat 1, and bead 2 can only be at the artificial action lower swing, prevent children should be curious and easily bead rich to the neck maybe, avoided dangerous generation.
And when curtain was not installed, bead was in locking state, and bead can not shuttling movement under the pulling of external force, also avoided children because of curiosity pulling bead make its motion maybe.Even thereby under uninstalled situation, also avoided dangerous generation.
