Description
Technical field
The utility model relates to a kind of glasses, more particularly, relates to a kind of extension type Anti-falling glasses.
Background technology
Glasses are as requisite instrument in myopia or farsightedness user live and work, play an important role in people's life, but when wearing spectacles process, glasses are easily dropped when colliding by external force, eyeglass milli is non-cushioned to be fallen on the ground, is easy to be broken.Simultaneously because mirror holder length is fixed, different user can not regulate the length of mirror holder as required when wearing spectacles, very inconvenient.
Utility model content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of extension type Anti-falling glasses.
The utility model solves the technical scheme that its technical matters adopts: construct a kind of extension type Anti-falling glasses, these glasses comprise picture frame and mirror holder, this picture frame comprises housing, be arranged at " work " type fixed block with this housing elastic movable supports in this housing, eyeglass is fixed on this " work " type fixed block, this mirror holder comprises first body of rod and second body of rod, this second body of rod is slidably sheathed in this first body of rod, one end that this second body of rod stretches in this first body of rod is provided with tooth bar, the gear that can rotate in this first body of rod is provided with in this first body of rod, this gear engages with this tooth bar, the latch be inserted into from this first body of rod in this first body of rod is provided with in this first body of rod, the projection of this tooth bar is blocked when this latch end is provided with insertion, the first spring is provided with between this projection and this first body of rod inwall, this first spring housing is located on this latch.
In extension type Anti-falling glasses described in the utility model, this housing inner side edge should be arranged at respectively by " work " type fixed block, should be connected by the second spring with this housing madial wall by " work " type fixed block.
In extension type Anti-falling glasses described in the utility model, this second rod end is provided with the block preventing this second body of rod from deviating from this first body of rod.
Implement extension type Anti-falling glasses of the present utility model, there is following beneficial effect: when using glasses of the present utility model, when needs regulate mirror holder length, latch is pulled upwardly, make protruding disengaging tooth bar, now, second body of rod can inwardly or be pulled out to regulate the length of mirror holder, after having regulated, unclamp latch, again snap in tooth bar under the elastic restoring force effect of the first spring of latch, the motion of restriction tooth bar, can play the effect regulating mirror holder length.Simultaneously when glasses are dropped, because eyeglass is connected with housing elasticity by " work " type fixed block, buffer protection function is played to eyeglass, prevents eyeglass from being broken.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model extension type Anti-falling glasses.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, in extension type Anti-falling glasses first embodiment of the present utility model, construct a kind of extension type Anti-falling glasses 1, these glasses 1 comprise picture frame 2 and mirror holder 3, this picture frame 2 comprises housing 4, be arranged at " work " type fixed block 5 with this housing 4 elastic movable supports in this housing 4, eyeglass is fixed on this " work " type fixed block 5, this mirror holder 3 comprises first body of rod 7 and second body of rod 8, this second body of rod 8 is slidably sheathed in this first body of rod 7, one end that this second body of rod 8 stretches in this first body of rod 7 is provided with tooth bar 9, the gear 10 that can rotate in this first body of rod 7 is provided with in this first body of rod 7, this gear 10 engages with this tooth bar 9, the latch 11 be inserted into from this first body of rod 7 in this first body of rod 7 is provided with in this first body of rod 7, the projection 13 of this tooth bar 9 is blocked when this latch 11 end is provided with insertion, the first spring 12 is provided with between this projection 13 and this first body of rod 7 inwall, this first spring 12 is sheathed on this latch 11.
When using glasses 1 of the present utility model, when needs regulate mirror holder 3 length, latch 11 is pulled upwardly, makes protruding 13 to depart from tooth bar 9, now, second body of rod 8 inwardly or can be pulled out to regulate the length of mirror holder 3, after adjustment completes, unclamp latch 11, again snap in tooth bar 9 under the elastic restoring force effect of the first spring 12 of latch 11, restriction tooth bar 9 moves, and can play the effect regulating mirror holder 3 length.Simultaneously when glasses 1 are dropped, because eyeglass is connected with housing 4 elasticity by " work " type fixed block 5, buffer protection function is played to eyeglass, prevents eyeglass from being broken.
Further, this housing 4 inner side edge should be arranged at respectively by " work " type fixed block 5, should be connected by the second spring 6 elasticity with this housing 4 madial wall by " work " type fixed block 5.
Further, this second body of rod 8 end is provided with the block 14 preventing this second body of rod 8 from deviating from this first body of rod 7.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
