Abstract

The utility model relates to a fastening mechanism of a key ring. The utility model mainly adopts the structure that a fastener is pivoted on a main body of a key ring, wherein, a cutting groove is respectively and longitudinally arranged on both ends of the fastener and can be respectively buckled and abutted against both ends of a main body of a hook-shaped key ring, a containing part which can contain an elastic element is arranged in the fastener, and thus, the fastener and the main body of a key ring can form a moderate clamp and buckling resultant force, wherein, the fastener is integrally formed of plastic materials through die sinking and die-casting, so as to guarantee that the containing part and the cutting grooves in the fastener are arranged centrally and are not deflected; thereby, the fraction defective of products is lowered, and then, production cost is reduced.

Description

The key-ring clip connection device

Technical field

The utility model relates to a kind of key-ring, particularly a kind of key-ring clip connection device.

Background technology

General buckled key-ring and fastener thereof mainly are through lathe by metal material, boring, again through the milling machine tangent plane, at last by polishing and step such as plating, to make integral body reach attractive in appearance, effects such as novelty, when assembling, because cutter is provided with the holding part and the grooving that can supply the elasticity element to put in the clasp, can be when fastener be articulated in the key-ring body, and the clip that makes fastener and key-ring body form an appropriateness fastens power, with the snapping key or be held on the article of pre-snapping and unexpected coming off, hold effect though this kind processing procedure can be reached basic button, still have to have following shortcoming:

One, the holding part on the fastener, when puncher is given a farfetched interpretation through hole, need fastener aligned and put, the unexpected deflection of can punchinging, but during because of the puncher Drilling, because of rotating the excessive situations such as fastener generation landing or skew that often make of torsion, cause fastener and the key-ring body can't be involutory, and then increase the generation of fraction defective.

Two, fastener needs one by one through steps such as lathe, boring, milling machine tangent plane, polishing and plating, can articulate with the key-ring body, but because this kind processing procedure is not only consuming time, power consumption, and each step needs after certain hour and the test of artificial specification, just can carry out next step, and seriously increase dealer's cost problem.

Summary of the invention

The utility model purpose provides a kind of key-ring clip connection device, this clip connection device can make really holding part in the fastener and grooving place in the middle of and deflection not and then reduces the fraction defective of product.

Above-mentioned purpose of the present utility model is achieved in that a kind of key-ring deduction structure, it is characterized in that: key-ring body bending is colludes shape; The key-ring body respectively extends a top to two ends; Be horizontally set with a notch in a top appropriate location; Provide a hole that pivotly joins for the fastener pivot joint in this top side; Respectively be longitudinally set with a grooving in the fastener two ends, involutory mutually with two tops of key-ring body respectively, and but cutter is established the holding part of an ammunition feed sheet and spring storing in the grooving of fastener, outwards provide the hole that pivotly joins that supplies the rivet pivot joint respectively in the grooving predetermined position, the clip that can make fastener and key-ring body form an appropriateness by this fastens power, with the snapping key or be held on the article of pre-snapping and do not come off, wherein this fastener is one-body molded through die sinking die casting by plastic material, with make really holding part in the fastener and grooving place in the middle of and deflection not, each member is located really, prevent that the facts that fastener and key-ring body can't be involutory from taking place, and then reduce the fraction defective of product, and reach and simplify working process and reduce cost of manufacture.

Above-mentioned purpose of the present utility model, characteristics and advantage can become clearer by in the following detailed description with specific embodiment in conjunction with the accompanying drawings.

Description of drawings

Fig. 1 is the three-dimensional combination figure of the utility model one preferred embodiment;

Fig. 2 is the three-dimensional exploded view of the utility model one preferred embodiment;

Fig. 3 is the partial enlarged drawing of the utility model one preferred embodiment;

Fig. 3 A is the A-A cut-away view of Fig. 3;

Fig. 4 is the user mode schematic diagram of the utility model one preferred embodiment.

Drawing reference numeral explanation: 1 key-ring body; 11 tops; 111 notches; 112,211 pivotly join the hole; 2 fasteners; 21,21 ' grooving; 22 holding parts; 221 shell fragments; 222 springs; 3 rivets.

The specific embodiment

Fig. 1 is the three-dimensional combination figure of the utility model one preferred embodiment, simultaneously referring to shown in Figure 2, from figure, can be clear that, the utility model mainly is to be by a body 1 bending to collude shape, and extend a top 11 to two ends in body 1,11 ', 11 appropriate locations are horizontally set with a notch 111 in the top, and provide one in side and can pivotly join hole 112 for what fastener 2 articulated, wherein, this fastener 2 is one-body molded by die sinking die casting, its length slightly is longer than the breach of key-ring body 1, respectively be longitudinally set with a grooving 21 in fastener 2 two ends, 21 ', can be respectively and the top 11 of body 1,11 ' is involutory, but cutter is established the holding part 22 that an ammunition feed sheet 221 and spring 222 put in the grooving 21 of fastener 2, and outwards provide respectively and can pivotly join hole 211 for what rivet 3 articulated in the predetermined position of grooving 21.

When combination, the shell fragment 221 that is arranged with spring 222 is placed in the holding part 22 of buckle spare 2, and the top 11 on the grooving 21 that makes fastener 2 and the key-ring body 1, pivotly join hole 112,211 by what a rivet passed key-ring body 1 and snapping portion 11, and be a pivot joint state, and make shell fragments 221 in the fastener 2 be resisted against notch 111 on the key-ring body 1, promptly finish combination (as shown in Figure 2); When using, fastener 2 inwardly can be pulled, in order to wearing article or key-ring body 1 being buckled in (as shown in Figure 4) on the thing of withholding; And by spring in the buckle spare 2 222 and shell fragment 221, and make buckle spare 2 and the clip that key-ring body 1 forms an appropriateness fasten power.

Wherein, this fastener 2 is one-body molded through die sinking die casting by plastic material, to make holding part 22 and grooving 21,21 ' in the fastener 2 place middle and unexpected deflection (referring to Fig. 3,3B) really, each member is located really, prevent that the facts that fastener 2 and key-ring body 1 can't be involutory from taking place, and then the fraction defective of reduction product, and reach the structure of simplifying working process and reducing cost of manufacture.

By the above as can be known, key-ring fastening structure of the present utility model has the generation that reduces fraction defective really, and reduces cost of manufacture, and has the effect that environmental protection economizes energy concurrently.

The above is preferred embodiment of the present utility model only, is not to be used for limiting the scope that the utility model is implemented, and all equalizations of doing according to the utility model training centre change and modify, and are all the utility model protection domain and contain.
