The specific embodiment

Existing key with key ring, because the needs of injection mo(u)lding, its key body is divided into upper shell and lower house, key ring also correspondingly is divided into the first half and the latter half, the first half of key ring and the latter half are one-body molded with upper shell and the lower house of key body respectively when injection moulding, be combined into a complete key with key ring by modes such as buckles at last, such as Fig. 1 and Fig. 2.The integrated key of this key ring and key body in injection mo(u)lding, because one-body molded portion structure is complicated, has increased difficulty and the technique of injection moulding.Therefore, need a kind of key with key ring that is easy to injection mo(u)lding of design.

Below in conjunction with accompanying drawing the technical scheme among the utility model embodiment is described in detail.

Please in conjunction with Fig. 3, Fig. 4 and Fig. 5, the utility model has disclosed a kind of key with key ring, comprise key body and key ring 3, key body comprises upper shell 1 and lower house 2, upper shell 1 and lower house 2 can cooperate up and down by buckle or the mode such as gluing, thereby form a complete key body.

In the utility model preferred embodiment, two free ends of key ring 3 are arranged in the engaging space of upper shell 1 and lower house 2, and its main part exposes outside.So arrange, key ring 3 is detachable with respect to key body, thereby makes key ring 3 be independent of key body.Key ring 3 and its structure of key body after separate are simpler, and required Shooting Technique is relatively more simple, has reduced the mould difficulty, thereby have improved production efficiency, reduced cost of production.

In the utility model preferred embodiment, key ring 3 takes the shape of the letter U, and two free ends of key ring 3 are angular bend with respect to the body of key ring 3.Two of key ring 3 free ends are angular bend with respect to the body of key ring 3 herein, and following several implementation can be arranged:

Embodiment one:

Two free ends of key ring 3 are in the angular bend that body planar is of key ring 3, when free-ended angle of bend is 90 when spending, key ring 3 roughly is " Ω ", be provided with two grooves with key ring 3 places of matching on the upper shell 1 of key body or lower house 2, this groove is used for accommodating two free ends of key ring 3.During assembly unit, only need two free ends of key ring 3 are embedded this groove, then with upper shell 1 or lower house 2 engagings, thereby form a complete key with key ring.

Embodiment two:

Two free ends of key ring 3 are angular bend in the plane perpendicular to plane, key ring 3 place, and on the upper shell 1 of key body or lower house 2, be provided with two grooves with key ring 3 places of matching, these two grooves correspondingly are the angle setting, to accommodate two free ends of key ring 3.Erection method is same

Embodiment one.

Embodiment three:

Two free ends of key ring 3 are 90 degree in the plane perpendicular to plane, key ring 3 place crooked, as shown in Figure 4, and on the upper shell 1 of key body or lower house 2, being provided with two holes 4 with key ring 3 places of matching, these two holes 4 are in order to accommodate two free ends of key ring 3.Erection method is same

Embodiment one.

Certainly, except as being undertaken the assembly unit by the buckle form between embodiment one to three described key ring 3 and upper shell 1 or the lower house 2, also can with the key ring 3 of in advance moulding when upper shell 1 or lower house 2 injection moulding and upper shell 1 or lower house 2 one-body molded, this integrated mode not only need not to be pre-formed groove or hole at upper shell 1 or lower house 2, and has saved the assembly unit operation.

In the utility model preferred embodiment, key ring 3 is arranged on the upper shell 1 end away from key piece.Certainly, key ring 3 also can be arranged on the lower house 2 end away from key piece, the sidepiece of upper shell 1, the perhaps sidepiece of lower house 2.

In the utility model preferred embodiment, but key ring 3 also can adopt the bar punch forming except injection mo(u)lding, and is simple in structure, can produce in batches.After the punch forming, can electroplate separately, to increase abrasion resistance and product overall appearance.

The key with key ring that the utility model discloses, comprise key body and key ring 3, key body comprises upper shell 1 and lower house 2, upper shell 1 and lower house 2 cooperate up and down, two free ends of key ring 3 are arranged in the engaging space of upper shell 1 and lower house 2, and its main part exposes outside.So arrange, key ring 3 is detachable with respect to key body.Because independent mutually between key ring 3 and the key body, be assembled into respectively a complete key with key ring after the injection mo(u)lding, and each modular construction after splitting is relatively simple, required Shooting Technique is relatively more simple, reduce the mould difficulty, thereby improved production efficiency, reduced cost of production.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, in other embodiments realization.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
