Description
Technical field
The utility model belongs to personal ornament parts, particularly a kind of Necklace fastener.
Background technology
As shown in Figure 5, known Necklace fastener system is made up of pin thread 10, box 20 and spring 202.During winding, be connected with elongate body such as chain or line 30 two ends respectively, to constitute necklace with pin thread 10 and box 20 outer ends.Pin thread 10 the inners are convexly equipped with projection 101, and are arranged with card ditch 102 in projection 101 front-end table sides, and card ditch 102 is to be by the axial importing ditch 103 that is connected in regular turn, radially to accept L shaped that ditch 104 and axial fastening ditch 105 constitute.Box 20 the inners are the hollow form sleeve 201 corresponding and sheathed with the inner projection of pin thread 10 101, and sleeve 201 front inner wall are convexly equipped with card grain 203.Spring 202 is mounted in the box 20 inner sleeves 201, and supports to be stuck on the card grain 203 and locate.
When wearing necklace, be that elongate body 30 is suspended from the front, and after pin thread 10 and box 20 extended neck respectively; When desire fastens pin thread 10 and box 20, as shown in Figure 6, be that sleeve 201 with box 20 is corresponding and be sleeved on the projection 101 of pin thread 10, and make card grain 203 it in the importings of sliding of the importing ditches 103 of projection 101 card ditches 102, to make projection 101 elastic compression springs 202; Then, as shown in Figure 7,, card grain 203 is slided in accepting ditch 104 again with box 20 and pin thread 10 relative backward rotation one strokes; Continue it, as shown in Figure 8, decontrol pin thread 10,,, the card grain 203 of box 20 is slided in fastening ditch 105 and only block the projection 101 outside contacts of pin thread 10 by the elastic-restoring force of spring 202.By this, can fasten pin thread 10 and box 20.
This known Necklace fastener is being made, when using, is being remained in following shortcoming:
1, need be arranged with L-shaped card ditch 102 in pin thread 10 projections 101 surfaces, so long processing time.
2, because of the user operates pin thread 10, box 20 when wearing necklace often behind neck, because card ditch 102 is L-shaped, so when fastening pin thread 10 and box 20, operation is trouble.That is, with the projection 101 of pin thread 10 and sleeve 201 fits of box 20, after card grain 203 is slided in importing ditch 103, need pin thread 10 and box 20 relative counter-rotating one strokes, card grain 203 is slided in accepting ditch 104, utilize spring 202 with pin thread 10 outer tops again, card grain 203 is slided and card fastening position in fastening ditch 105.
Summary of the invention
The purpose of this utility model provides a kind of processing Necklace fastener simple, easy to use of making.
The utility model comprises pin thread, box and spring; Pin thread the inner is convexly equipped with projection, and is arranged with in projection front-end table side and is √ shape Ka Gou; The inclination fastening ditch that √ shape Ka Gou system imports ditch by inclination and the importing ditch rear end bending of tilting certainly extends constitutes; Box the inner is and the corresponding and sheathed hollow form sleeve of the inner projection of pin thread, and the barrel forward end inwall is convexly set in and slides in the pin thread √ shape card ditch and card card grain only; Groups of springs is located in the inner sleeve of box, and to being stuck on the card grain.
Because the utility model comprises pin thread, box and spring; Pin thread the inner is convexly equipped with projection, and is arranged with in projection front-end table side and is √ shape Ka Gou; The inclination fastening ditch that √ shape Ka Gou system imports ditch by inclination and the importing ditch rear end bending of tilting certainly extends constitutes; Box the inner is and the corresponding and sheathed hollow form sleeve of the inner projection of pin thread, and the barrel forward end inwall is convexly set in and slides in the pin thread √ shape card ditch and card card grain only; Groups of springs is located in the inner sleeve of box, and to being stuck on the card grain.During winding, be connected with elongate body two ends such as chain or lines respectively, to constitute necklace with pin thread and box outer end.When wearing necklace, be that elongate body is suspended from the front, and after pin thread and box extended neck respectively; And corresponding and be sleeved on the projection of pin thread with the sleeve of box, and make card grain it on import the ditch importing of sliding of taking advantage of a situation in the inclination of projection front-end table side Ka Gou, to make the projection elastic compression spring; After slipping over the turning that tilts to import ditch and inclination fastening ditch when card grain, decontrol pin thread,,, the card grain of box is taken advantage of a situation slip into inclination fastening ditch interior and block the fastening position the outside contact of the projection of pin thread by the elastic-restoring force of spring; Ka Gou system is simple √ shape, so make weak point process time; During operation, need not relatively rotate the male and female button, so operation is simpler and easy, quick.It is simple not only to make processing, and easy to use, thereby reaches the purpose of this utility model.

The specific embodiment
As shown in Figure 1, the utility model comprises pin thread 1, box 2 and spring 22.
During winding, be connected with elongate body such as chain or line 3 two ends respectively, to constitute necklace with pin thread 1 and box 2 outer ends.
When wearing necklace, be that elongate body 3 is suspended from the front, and after pin thread 1 and box 2 extended neck respectively; When desire fastens pin thread 1 and box 2, as shown in Figure 2, system is corresponding and be sleeved on the projection 11 of pin thread 1 with the sleeve 21 of box 2, and makes card grain 23 it on import ditch 121 importing of sliding of taking advantage of a situation in the inclinations of projection 11 front-end table side card ditches 12, to make projection 11 elastic compression springs 22; Continue it, as shown in Figure 3, Figure 4, slip over the turning of importing ditch 121 and inclination fastening ditch 122 when card grain 23 after, decontrol pin thread 1, elastic-restoring force by spring 22, with the projection 11 outside contacts of pin thread 1, the card grain 23 of box 2 is taken advantage of a situation slip in the inclination fastening ditch 122 and block the fastening position.By this, can fasten pin thread 1 and box 2.
As mentioned above, the utlity model has following advantage:
1, card ditch 12 is to be simple √ shape, so make weak point process time.
2, because card ditch 12 is to be simple √ shape, so when fastening pin thread 1 and box 2, operate simple and easy.That is, behind sleeve 21 fits with the projection 11 of pin thread 1 and box 2, as long as being slipped into, card grain 23 tilts to import ditch 121, after the guiding of tilting to import ditch 121 slides to importing ditch 121 degree of depth, decontrol pin thread 1, can cooperate the elastic-restoring force of spring 22, card grain 23 is taken advantage of a situation slip in the inclination fastening ditch 122, and need not relatively rotate male and female button 1,2, so operation is simpler and easy, quick.
