Abstract

The utility model relates to an improved mother-son typed fastening structure, which mainly comprises a mother seat and a son seat. The entity of the mother seat is provided with a through slot and a side slot; the side slot is communicated with the through slot; while the son seat is provided with a penetrating and extending component and a limited wing extended out of the terminal of the penetrating and extending component; the limited wing is relatively corresponding to the through slot of the mother seat; the penetrating and extending component and the limited wing can directly penetrate and extend into the through slot and the side slot of the mother seat. By means of the rotary action and the position change of the son seat, the utility model make the fastening of an object more smooth and the style of the object more changeable and plays the effects of various ornaments and toys.

Description

The primary-secondary type fastening structure of improvement

The utility model is the primary-secondary type fastening structure about a kind of improvement.

Traditional primary-secondary type fastening structure, establish a slotted eye on its female seat, can fix with the projection and the rotating disk inlay card of dorsal part for stroma, and the rotation that utilizes rotating disk is positioned on the female seat stroma, one female seat can be changed, to be useful in article such as various ornaments, toy, bob chain and hair clip respectively with a plurality of stromas.

The present utility model people through further investigation after, think traditional primary-secondary type fastening structure, in addition room for improvement is still arranged, so that it reaches more perfect boundary, for this reason, the inventor initiates a kind of primary-secondary type fastening structure of improvement through long-term test experiments.

The purpose of this utility model provides a kind ofly more has superiority than traditional primary-secondary type fastening structure, the primary-secondary type fastening structure of more perfect improvement.

The figure number explanation:

1 female seat, 2 grooves, 20 limit grooves, 3 stop blocks, 4 short slots, 41 stop sections, 5 protruding grains, 6 stromas, 7 parts that stretch through, the 70 restriction wings, 8 grooves, 80 limit grooves, 81 stop sections, 82 parts that stretch through, the 83 restriction wings, 9 parts that stretch through, the 90 restriction wings, 91 grooves, 92 limit grooves, 93 stop sections.

Consult Fig. 1, shown in Figure 2, the utility model main member includes:

Female seat 1, can be the entity that commercialization also can be designed to different shape, for convenience of description, now describe with disc-shape, female seat 1 entity appropriate location is preset with the cylindrical groove 2 that runs through, and on groove 2, be provided with at least one group coupled logical and be all the limit groove 20 that runs through, simultaneously on female seat 1 back side entity, be preset with a stop block 3, these stop block 3 entities are preset with at least one short slot 4 to form stop section 41, be provided with in addition the suitable protruding grain of height in groove 2 and limit groove 20 joints, this protruding grain can be single, two grains even many s' setting.Groove on the female seat entity and limit groove can be cross, M shape or other shapes.

Stroma 6 can combine and can be the entity of various different shapings design with female seat 1, be preset with the column type part 7 that stretches through on the entity face, and is extended with at least one group the correspondence restriction wing 70 in the terminal both sides of the part 7 that stretches through.

Situation is implemented in combination of the present utility model, it is the groove 2 that mainly utilizes part 7 correspondences that stretch through to wear stroma 6 to be combined in female seat 1 set, and make 70 pairs on the wing of restriction be combined in limit groove 20, and make stroma 6 tentatively be linked in (its detailed situation is shown in Fig. 3,4) on the female seat 1, by the set protruding grain 5 of limit groove 20 and groove 2 joints, the restriction wing 70 of stroma 6 is obstructed 5 of protruding grains, and make stroma 6 unlikely disengaging female seats 1, adopt the manner of this kind architecture design, then at stop block 3 sidepieces stop section 41 and short slot 4 need not be set, its combination and enforcement situation such as Fig. 8 are to shown in Figure 11.

Female seat 1 set groove and limit groove of the present utility model is not limited only to specific unmodifiable shape in addition, sees also shown in Figure 12.Former cylindrical groove can be designed to rectangle or square, be provided with a limit groove 80 than minor diameter at rectangle or square three-way groove 8 appropriate locations, and be equipped with a circular hole, and be provided with a stop section 81 in circular hole one side, the stroma 6 former cylindrical parts that stretch through also can change to rectangle or square tube groove 8 simultaneously, be all rectangle or squared design, and be extended with the restriction wing 83 equally at rectangle or square part 82 ends that stretch through, its combination and enforcement situation, then be the restriction wing 83 to be installed with in limit groove 80, be displaced downwardly to the circular hole place, again with stroma 6 rotations, make the restriction wing 83 be obstructed in the stop section 81, reach the fixedly purpose of stroma 6 (situation such as Figure 13 arrive shown in Figure 16 in detail) and stroma 6 and female seat 1 can not separated.

Stroma 6 of the present utility model again is similarly and not only is confined to specific shape, see also Fig. 7 to shown in Figure 21, the design outward appearance body of stroma 6 can be the moulding of various animals, on stroma 6 entities, be provided with rectangle or the square part 9 that stretches through equally, end is extended with the restriction wing 90 equally, female seat 1 also can be designed to rectangle or square simultaneously, on entity, be provided with rectangle or square groove 91 equally, limit groove 92, and connect and establish a circular hole, and be provided with stop section 93 in circular hole one side, for the people who uses with its inclination, select the stroma 6 of different shaping to cooperate female seat 1 mutual build-in location, and do various variation, cooperatively interact down by the different grooves and the part that stretches through simultaneously, and play various ornaments, the effect of toy.Compare with traditional primary-secondary type fastening structure, perfect and excellent more.
