Abstract

The utility model provides glasses catapult component, it is characterized by comprising catapult compartment cavitys, catapult compartment cavity has inner cavity, and inner cavity is equipped with slingshot core, and slingshot core is embedding to be adapted in the lumen, inner cavity has inside groove and notch, notch is communicated with inside groove, and the bottom of inside groove is lower than the bottom of notch, and inside groove is at least provided with a pair of of pillar, a pair of of pillar is separately mounted to inside groove side wall, and two pillars are drawn close to inside groove middle part to be enclosed with slingshot core side with gap.The utility model has the beneficial effects that: the design structure is simple, service life is improved, the angle that earpiece can be kept to expand for a long time deviation will not occur because wearing the time, greatly reduce mirror pin expansion problem.

Description

Glasses catapult component

Technical field

The utility model relates to glasses accessory, in particular to glasses catapult components.

Background technique

Existing spectacle frame, is generally made of frame and temple, by screw connection between frame and temple, due to considering The stabilization of present position need to be kept when opening or packing up to leg of spectacles, traditional eyewear is in the connecting portion inner cavity of temple and frame In, fixed assembling is cased with the catapult component of spring, but since long-time uses, spring can generate elastic fatigue, or even damage, Cause frame is opposite with temple to generate relaxation, not only cause with the inconvenience taken, but also may be because frame eyeglass Positional shift and be unable to reach expected vision correction effect, thus influence the use of spectacle frame, if there is damage, mirror pin is needed Often relatively difficult when replacing, catapult is as glasses accessory one kind, and wherein elastic fatigue easily occurs in the spring in catapult component Phenomenon is primarily due to be that spring will appear positional shift in use, service life is caused to shorten.

Summary of the invention

The utility model in view of the above-mentioned problems existing in the prior art, provides glasses catapult component.

The goal of the invention of the utility model is realized by following scheme:

Glasses catapult component, it is characterised in that: including catapult compartment cavity, catapult compartment cavity has inner cavity, and inner cavity is equipped with Slingshot core, slingshot core is embedding to be adapted in the lumen, and inner cavity has two inside grooves and notch communicated, and it is straight that internal slot diameter is greater than notch Diameter, communicates with inside groove place's inside groove and has and contradict end face in notch, and slingshot core includes spring and the catapult that is connected with spring, spring It being placed in inner cavity and is contradicted with end face is contradicted, for inside groove at least provided with a pair of of pillar, a pair of of pillar is separately mounted to inside groove side wall, and two Pillar is drawn close to inside groove middle part to be enclosed with the spring side of slingshot core with gap.

Preferably, pillar is equipped with two pairs, and two pairs of pillars are sequentially arranged in inside groove side wall.

Preferably, two pairs of pillars etc. point mode is arranged on interior trough rim wall.

Preferably, the opposite space formed of two pillars is not less than width of rebate.

Preferably, pillar with a thickness of 0.5-0.9mm.

Preferably, notch outer end is equipped with two convex edges, and two convex edges outwardly protrude by two side wall of notch and formed, two convex edges it is opposite away from From of same size with the notch.

The utility model has the beneficial effects that: the design structure is simple, service life is improved, can be kept for a long time The angle of earpiece expansion, deviation will not occurs because wearing the time, greatly reduce mirror pin expansion problem, and the design is additionally arranged There is the problem of swinging to place spring in pillar, and spring can be allowed to be in elastic stage for a long time, reduces mirror pin vibration problems, together When be additionally arranged convex edge and can guarantee that catapult will not occur with mirror pin having gap because using, cause mirror pin not firm and appear in Problem is loosened during wearing.

Detailed description of the invention

Fig. 1 is the utility model overall structure diagram；

Fig. 2 is the structural schematic diagram equipped with two pairs of pillars.

Specific embodiment

Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.

Embodiment

Referring to shown in attached drawing 1, Fig. 2, glasses provided by the utility model catapult component, including catapult compartment cavity 1, catapult Compartment cavity has inner cavity, and inner cavity is equipped with slingshot core, and slingshot core is embedding to be adapted in the lumen, and inner cavity has inside groove 2 and notch 3, slot Mouthfuls 3 communicate with inside groove 2, and the bottom of inside groove is lower than the bottom of notch, and slingshot core includes spring and the catapult that is connected with spring, bullet Spring is mounted on catapult, and spring is placed in inner cavity and contradicts with end face 6 is contradicted, and inside groove is at least provided with a pair of of pillar 4, a pair of of pillar 4 are separately mounted to inside groove side wall, and two pillars are drawn close to inside groove middle part to be enclosed with the spring side of slingshot core with gap, and be in contact mode Including conflict and gap-contact etc., pillar effect, which is mainly played, is firmly stuck in one the spring in catapult core components Horizontal direction will not move in the horizontal direction, it will not be allowed because occurring deviation in processing or use process, improve product Stability and wearing comfort.

In order to further increase stability, pillar is equipped with two pairs, and two pairs of pillars are sequentially arranged in inside groove side wall.It is preferred that Ground, two pairs of pillars etc. point mode are arranged on interior trough rim wall.

For the reliability of processing, the opposite space formed of two pillars is not less than width of rebate.Preferably, the thickness of pillar For 0.5-0.9mm.

In order to further accomplish to prevent slingshot core from deviating, two convex edges 5 are equipped in notch outer end, two convex edges are by notch two Side wall outwardly protrudes to be formed, and two convex edge relative distances are of same size with the notch.

Be described further to the design: width of rebate and interior groove width are than being about 1:2 in the design；Wherein pillar is big The 2/3 of small about notch, it is in this case, the most stable.

Although the utility model is shown and described by reference to preferred embodiment, this field is common Technical staff is it is to be appreciated that the description that can be not limited to the above embodiments, within the scope of the claims, can make form and Various change in details.
