Description
Technical field
The utility model relates to a kind of structural member of glasses non optical component, relates in particular to a kind of 180 ° of rotation catapult Leg.
Background technology
A pair of glasses generally comprises mirror holder and mirror pin, is furnished with eyeglass on mirror holder.At present, the glasses of being sold on the market mostly adopt the connected mode of HINGE SCREWS that both are linked together between mirror holder and mirror pin, and the use of HINGE SCREWS makes that the style of glasses is single, and style is also more vulgar.
A kind of HINGE SCREWS connected mode that do not rely on is arranged simultaneously at present, structurally comprise catapult head and catapult body, in the catapult head, spring is installed, a screw links together catapult head and catapult body by spring simultaneously, but owing to spacing structure is not set on one's body at catapult head and catapult, often rotational angle is excessive easily between catapult head and the catapult body, damages the spring of the inside, has reduced serviceable life.
And a kind of " glasses catapult leg ", the patent No. is 02225619.9, comprises village head, leg of spectacles, cannulated sleeve, compression spring and sliding sleeve; The complete opening of described cannulated sleeve front end, rearward end is provided with the stopper slot of leg of spectacles, and the inboard of this stopper slot is darker, and the outside is more shallow; The complete opening of described sliding sleeve head, compression spring is put into its inner chamber from opening part, and the afterbody of sliding sleeve is provided with the protruding key of semisphere; Described leg of spectacles has the spherical recess that circular arc enlarged footing, this enlarged footing top, inside and outside both sides respectively have an energy and described protruding key cunning to join; The shaft-like bad line of leg of spectacles passes from the stopper slot of cannulated sleeve, and its enlarged footing is limited in the inner chamber of cannulated sleeve, in compression spring is housed the sliding sleeve afterbody put into cannulated sleeve inwardly, this sliding sleeve can be free to slide in the chamber within it along the tube wall of cannulated sleeve.Though said structure makes glasses have a kind of novelty to a certain extent, unique style, structure are too complicated to be damaged easily.
Summary of the invention
The utility model mainly is to solve above-mentioned technical matters, thereby provides a kind of simple in structure, and novel fashion is not fragile, long-lived 180 ° of rotation catapult Leg.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: comprise catapult head and catapult body, in the catapult head, spring is installed, a screw links together catapult head and catapult body by spring simultaneously, described catapult head is provided with the layback projection, is provided with the layback spacing block set that cooperates with the projection of swinging back on one's body at catapult.
In the utility model, the catapult head is connected with mirror holder, and the catapult body is connected with the mirror pin, realizes the folding of mirror pin when using glasses by the rotation of catapult head and catapult body.But when the angle of the outside layback of catapult head is excessive, spring to the inside causes damage easily, reduced serviceable life, so the suitable the unknown at catapult head and catapult body is provided with as the layback projection of spacing usefulness and the spacing block set of swinging back, can guarantee that catapult head and catapult move between certain angle, avoid causing damage because of angle is excessive, this angle can be adjusted as required.Such structure, also more novel fashion.
As preferably, have a through hole and a threaded hole in the both sides of catapult body, described layback spacing block set is arranged on the medial surface of through hole one side by the place, bottom.
Because catapult body and catapult head are connected on one by turnbuckle, need each other to rotate, the medial surface that the layback spacing block set is arranged on through hole one side is by the place, bottom, can guarantee that catapult body and catapult head rotate within certain scope smoothly, the size shape of layback spacing block set can be looked after and guided as required.
As preferably, maximum angle can reach 180 ° between described layback projection and the layback spacing block set.
Maximum angle between layback projection and the layback spacing block set reaches 180 ° of projections that can guarantee to swing back and can guarantee at 90 ° with the rotating of layback spacing block set, this angle is for general eyeglasses-wearing the time, and the needed angle of mirror pin folding has enough satisfied.
As preferably, during 90 ° of inside dextrorotations of described catapult head, angle is 180 ° between layback projection and the layback spacing block set, and when catapult head outwards during 90 ° of layback, the layback projection joins with the layback spacing block set and blocks.
When causing wearing spectacles, angle is about 90 ° between layback projection and the layback spacing block set; When closing up glasses, i.e. during 90 ° of inside dextrorotations of catapult head, the layback projection with swing back that angle is about 180 ° between the spacing block set; In the time of wearing spectacles, the catapult head still can outwards be swung back in 90 °, as adjusting.In case catapult head outwards layback reaches 90 °, the layback projection will block each other with the layback spacing block set, prevents the excessive damage spring of angle.
The utility model is by being provided with the layback projection and at catapult the layback spacing block set that cooperates with the projection of swinging back being set on one's body on the catapult head, feasible the utlity model has simple in structure, novel fashion, not fragile, long-lived advantage.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the utility model comprises catapult head 1, catapult body 3, spring 5 and screw 6.Described catapult head 1 is enclosed within the inside of catapult body 3, spring 5 is installed in catapult head 1, and simultaneously an end of spring 5 stretches out catapult head 1, and has screw 6 to pass spring 5 catapult head 1 is connected with catapult body 3, can be between catapult head 1 and the catapult body 3 to changing rotation, angle is within 180 °.
As Fig. 2, shown in Figure 3, catapult head 1 is provided with layback projection 2, this layback projection 2 is arranged on the outside of catapult head 1, when catapult head 1 cooperates with catapult body 3, swing back projection 2 in the inboard of catapult body 3, but do not contact with catapult body 3, described layback projection 2 is a boss that forms in catapult head 1 outside.
As Fig. 4, shown in Figure 5, catapult body 3 is provided with layback spacing block set 4, and this layback spacing block set 4 is arranged on catapult body 3 inboard positions by the bottom.Because screw 5 passes across whole catapult body 3, therefore the both sides of catapult body 3 have a through hole and a threaded hole respectively, described layback spacing block set 4 is a boss that forms on the catapult body 3, is arranged on the side by threaded hole, cooperatively interacts with layback projection 2.
As shown in Figure 6, when catapult head 1 was inwardly just changeing 90 °, the part that spring 5 stretches out catapult head 1 can join with catapult body 3, and the position is blocked.Reach 90 ° and work as the 1 outside layback of catapult head, layback projection 2 will block (referring to Fig. 7) each other with the spacing block set 4 of swinging back
