Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and the embodiments, the utility model is further elaborated.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

The utility model provides a kind of buckle structure, comprises the first buckling piece, the second buckling piece, buckle; Described first buckling piece is provided with clasp and button hole; Buckle shoulder is provided with at described second buckling piece side; Described buckle forms by detaining base and detaining arm; Described button base is provided with the axis that can snap in described clasp and insert described button hole; Described button arm is made up of the first button arm section and the second button arm section; Described first button arm section is provided with the first projection, and described buckle shoulder is provided with the second projection fastening described first projection when described button arm is fastened in described buckle shoulder; Described second protruding outward extending buckle shoulder is also provided with top board; The inverted draw cut that can snap in described top board is provided with between the described button arm and described button base of described buckle.

Owing to adopting the first projection of the first button arm section at buckle to be interlocked with the second projection in buckle shoulder, reach easy to operate object.

Below in conjunction with embodiment, realization of the present utility model is described in detail.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, be a kind of buckle structure that the utility model provides, comprise the first buckling piece 1, second buckling piece 2, buckle 3; First buckling piece 1 is provided with clasp 4 and button hole 5; Buckle shoulder 6 is provided with at the second buckling piece 2 side; Buckle 3 is made up of button base 7 and button arm 8; Button base 7 is provided with the axis 9 that can snap in clasp 4 and insert button hole 5; Button arm 8 is made up of the first button arm section 10 and the second button arm section 11; First button arm section 10 is provided with the first projection 12, and buckle shoulder 6 is provided with the second projection 13 fastening the first projection 12 when detaining arm 8 and being fastened in buckle shoulder 6; Second protruding 13 outward extending buckle shoulders 6 are also provided with top board 14; The inverted draw cut 15 that can snap in top board 14 is provided with between the button arm 8 and button base 7 of buckle 3; First protruding 12 and second projection 13 needs when designing slightly to misplace, and mainly relies on the upwards top power of top board 14 first protruding 12 and second protruding fastening to be put in place during fastening; So just there is firm fastening effect; Second button arm section 11 is close to the upper surface of the second buckling piece 2 when fastening, so just the fastening power of the first protruding 12 and second projection 13 can be distributed to equably the upper surface of the second fastener 2; Reach and fasten reliable object; Determine groove 15 to be close to top board 14 when fastening, top board 14 and the adhesive force of inverted draw cut 15 make the first projection 12 oriented second projection 13 reciprocal micro-displacements when fastening, and obvious second projection 13 also has identical antiposition to move; The power produced by this small deformation just makes buckle firmly to block; Due to the leverage of the second button arm section 11, only need gently press during operation and buckle just can be made to put in place, reach easy to operate object.

Further, the upper cover of the second buckling piece 2 is higher than buckle shoulder 6; The fastening position of arm section 10 is detained in the fastening position of the second button arm section 11 higher than first; Such design is to make top board 14 more reasonable to the upper surface transmission of the second buckling piece 2 with the adhesion of inverted draw cut 15, can extending the serviceable life of buckle 3.

Further, be provided with in the terminal of the second button arm section 11 portion that upwarps 16 being beneficial to and breaking into two with one's hands; Such finger just can easily snap in buckle 3 and be broken into two with one's hands, reaches easy to operate object further.

Further, the cross section of clasp 4 is C-shaped; The inner circle of clasp 4 and axis 9 are in clearance fit; The opening 17 of clasp 4 is slightly less than the diameter of axis 9; Clearance fit can make axis 9 freely can rotate in clasp 4, but gap is unsuitable excessive, can rotate just just to make axis 9, As time goes on, the friction of rotating can make gap increase, adopt C-shaped cross section structure can the increase in adequate compensation gap, axis 9 can not too be rocked; The diameter that opening 17 is slightly less than axis 9 can make clasp 4 while blocking axis 9, very convenient during installation buckle 3, directly can be clamp-oned by axis 9 from opening 17.

Further, inner circle and the axis 9 of button hole 5 are clearance fit; This is also the rotation facilitating buckle 3; Adopt button hole 5 and clasp 4 with the use of, on the one hand buckle 3 convenience is installed, can be first inserted in button hole 5 first by axis 9, then the other end of axis 9 is directly clamp-oned clasp 4; On the other hand, due to the use of button hole 5, buckle 3 is made to be connected more firm with the second buckling piece 2.

Further, on the second buckling piece 2 with second the contact position of detaining when arm section 11 fastens be provided with make to break into two with one's hands described in upwarp the more convenient recess in portion 18; It is just more convenient that such finger fastens buckle 3.

Further, the first projection 12 is projections of middle disjunction; Second projection 13 is the projections of the middle disjunction matched with the first projection 12; Buckle 3 can be made so stressed more reasonable; Strength when snapping in or break into two with one's hands is more soft.

The utility model additionally provides the fiber reel applying above-mentioned buckle structure and stays box, comprises the box body be square and the lid matched with box body; Lid side and box body hinged; Buckle structure is provided with at hinged offside; Corresponding first buckling piece 1 of box body, corresponding second buckling piece 2 of lid; Can exchange according to actual conditions during certain actual design; Hingedly make lid when opening and box body is butterfly-like; The opposite side that buckle 3 is arranged on hinged limit 21 can make the force-closed lid of the button of buckle 3 maximum; Certainly buckle 3 can be arranged on other sides except hinged limit according to actual conditions, this can determine according to actual conditions.

Further, box body and lid are provided with two buckle structures; Lid two ends effectively can be avoided so then to tilt, reach sealed waterproof effect.

Further, spool 19 is provided with in box body; Lid is also provided with observation panel 20; Spool 19, for optical fiber is spooled, is avoided optical fiber to fracture or puts mixed and disorderly; Observation panel 20 can adopt transparent organic glass sealing box cover, can observe inner optical fiber situation like this when closing upper box cover through observation panel 20; Also observation panel 20 place can be set to labelled place; These can be determined according to actual conditions.

In a word, the utility model is interlocked with the second projection in buckle shoulder owing to adopting the first projection of the first button arm section at buckle, reaches easy to operate object; The fiber reel provided at the utility model stays in box, owing to adopting above-mentioned buckle, reaches the object of folding with convenience.

The foregoing is only better embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
