Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and embodiments.
The scheme relates to a through hole female buckle, which comprises a female shell 1, a reverse buckle piece 2 and a copper ring 3 as shown in figures 1-2.
The back-off plate 2 is designed with two straight step structures 2a, 2b and an inclined step structure 2c, the inner sides of the two straight step structures 2a, 2b are correspondingly formed with a pin chamber 21 and a female chamber 22, and the pin chamber is provided with a through hole 211.
The core innovation point of the present invention is the design of the inclined step structure 2c, which has an inclined step surface 24 disposed obliquely upward, and the upper and lower end portions of the inclined step surface 24 correspond to an inclined lower end portion 241 and an inclined upper end portion 242. The inner side of the inclined step structure is correspondingly formed with an inclined chamber 23, and the inner edge of the inclined chamber is correspondingly formed by an inclined lower end part 241. The copper ring 3 is accommodated in the inclined chamber 23, and the inner ring portion 31 of the copper ring 3 extends out of the inclined lower end portion 241, thereby facilitating the snap-fit function.
The female shell 1 surrounds the inclined chamber 23, one end of the female shell 1 is bent inwards to form an edge covering 11 for the reverse buckle piece 2 to abut against the limit position, and the edge covering 11 is used as the side wall of the inclined chamber 23. The other end of the female housing 1 is bent horizontally inward to form a protective edge 12 horizontally surrounding the inclined step surface 24.
In the scheme, the back-off piece 2 is designed into a novel matching structure of two straight step structures and an inclined step structure 2c, the inclined step structure design mainly brings effects, firstly, the thickness of the whole back-off piece 2 can be properly reduced by flexibly adjusting the design of the accommodating position of the copper ring 3 in the inclined chamber 23, and the through hole female buckle is thinned. Preferably, the inclined lower end 242 is located between the inner ring portion 31 and the central diameter portion 32 of the copper ring 3, so that under the premise of the same copper ring structure, the copper ring is stably assembled, the buckling effect is ensured, and the height space of the female cavity 22 is utilized in a staggered manner through the inclined step surface structure, so that the thinning design of the whole thickness of the back-off piece 2 is realized.
Secondly, a triangular structure is formed between the protective edge 12 and the inclined step surface 24, and the bending position of the protective edge 12 is determined by the inclined upper end 242 of the inclined step surface 24, namely, the protective edge and the inclined step surface are matched with each other. The design of oblique rank structure 2c, the messenger corresponds the female casing 1 that surrounds this oblique rank structure 2c and can corresponds the design of increasing, the safe edge 12 that the level surrounds oblique rank face 24 promptly because oblique upper end 242 structure, make this safe edge 12 toward can be adjacent straight rank structure 2b direction increase the design, under the prerequisite that does not increase spare part, thereby make straight rank structure 2 b's part or part can be ingenious to hide in female casing 1, promote the roughness at the box back, it is effective to strengthen the box, firmly the riveting installation effect.
Preferably, the angle of the inclined step surface 24 is preferably controlled to be 45-75 degrees, and the inclined angle determines the height of the bead 12 (relative to the height of the straight step surface b of the straight step structure 2b) to some extent.
Preferably, the height of the inclined upper end 242 of the inclined step surface 24 is lower than the straight step surface b corresponding to the female chamber 22 (straight step structure 2 b); the protective edge 12 is arranged flush with or slightly lower than the straight step surface b.
The foregoing is only a preferred embodiment of the present invention and all equivalent changes and modifications made within the scope of the present invention are intended to be covered by the appended claims.
