Refering to Fig. 1, it illustrates the buckle structure according to a kind of embodiment of this utility model, wherein swing component is with fixing Unassembled state it is between axle.Specifically, buckle structure includes a fixing axle 10 and at least one swing component 20, swings Part 20 is pivotally connected to described fixing axle 10.

It is worthy of note, one end of described swing component 20 has at least one Access Division 30, the horizontal stroke of described Access Division 30 Cross section be shaped as one have incomplete annular jaggy so that described fixing axle 10 can partly be contained in described card Connect the inside in portion 30, as shown in Figures 2 and 3.Table in the contacting of contact outer surface and the described Access Division 30 of described fixing axle 10 Face S1 is the most adaptive, to guarantee the reliability being connected between Access Division 30 with fixing axle 10.

According to a preferred implementation of the present utility model, the shape of cross section of the contact inner surface S1 of Access Division 30 is Arc-shaped.In order to strengthen the steadiness being rotationally connected, prevent the unexpected abjection of internal generation from Access Division 30 of fixing axle 10, preferably It is that the shape of cross section of contact inner surface S1 is the central angle major arc more than 180 degree.

As it is shown in figure 1, it is worthy of note, so that two sidepieces of fixing axle 10 will not be hindered thus hold very much Easily just can be plugged into the inside of Access Division 30, the axial direction of fixing axle 10 having the side that at least two is straight and relative to each other. As a preferred embodiment, as it is shown in figure 1, being shaped like in have rotated the cydariform after 90 degree of fixing axle 10 cross section.Tool For body, the outline of described fixing axle 10 cross section includes two straightways relative to each other being positioned at left side and right side, i.e. First straightway 101 and the second straightway 102, and it is positioned at two arc sections relative to each other of the upper side and lower side, i.e. first Arc section 103 and the second arc section 104.

For ease of realizing the assembling between swing component 20 and fixing axle 10, refering to Fig. 1, it is preferable that described Access Division 30 Internal maximal clearance D3 more than the clearance D 2 of described breach, and the clearance D 2 of described breach more than said two straightway 101, Distance D1 between 102, above-mentioned is designed to be prevented effectively from because interference fit causes junction excessive compression that glue occurs to shovel, from And have influence on the quality of product.

Connecing of the circular arc of the first arc section 103 and the corresponding arc surface of the second arc section 104 and described Access Division 30 Touch inner surface S1 to contact with each other and adaptive, to further enhance the rotation reliability of swing component 20.First straightway 101 and second Straightway 102 makes fixing axle 10 be easily achieved to click into place.Optionally, described swing component 20 can be solid relative to described Dead axle 10 is at rotation with in surface at least 90 degree at described fixing axle 10 radially place.Said structure makes swing component 20 and fixing axle Assembling process between 10 is more time saving and energy saving, the rotation flexibility ratio of swing component 20 can also be effectively ensured simultaneously and connect reliable Property.

Meanwhile, the invention also discloses a kind of control to switch.This control switch includes a pressing plate 40 and extremely A few button 50, is provided with between described pressing plate 40 and described button 50 and has a said structure and card that feature combines buckles Structure.

Visible refering to Fig. 3, described fixing axle 10 is arranged on the middle part of described pressing plate 40, and one end of described swing component 20 is passed through Access Division 30 is connected to described fixing axle 10, and its other end may be connected to described pressing plate 40.

It is preferred that the other end of described swing component 20 has a clamping part 21, it is connected in described pressing plate 40 to coordinate Sidepiece, the middle part of described swing component 20 also vertically extends a jut 22, described jut 22 is arranged with return unit 23.One end of return unit 23 abuts to the bottom of swing component 20, and the other end of return unit 23 abuts to the upper surface of pressing plate 40, logical Cross above-mentioned design, it is possible to swing component 20 is rotated rapidly after the pressure applied by side, and in this discharge degree Rear fast quick-recovery is to stable poised state.

It is more fully understood that this case for the ease of those skilled in the art, this practicality is briefly described below in conjunction with Fig. 1 to Fig. 3 new The snap-fitting process of type buckle structure.Specifically, when needs assemble, as it is shown in figure 1, first by swing component 20 relative to Pressing plate 30 is placed vertically, then by the notch alignment of Access Division 30 near the position of fixing axle 10, in order to fixing axle 10 enters Enter the inside of Access Division 30, and be partly resisted against the contact inner surface S1 of arc.Owing to the left and right contact surface of fixing axle 10 is Flat, such that fixing axle 10 is easy for can be plugged into the inside of Access Division 30 in the case of without hindrance, treat After the curved upper surface of fixing axle 10 abuts to the arc contact inner surface S1 of Access Division 30, such as can by swing component 20 relative to Fixing axle 10 (as shown in Figure 2) turns clockwise about 90 degree so that the other end of swing component 20 can snap fit onto pressing plate 30 By a simple spinning movement, sidepiece, is so achieved that swing component 20 fastens with the locking of pressing plate 30.Set by above-mentioned Meter so that assembling process is the most laborsaving, the stability that structure connects is the highest, simultaneously it may also be ensured that swing component 20 is relative In the motility that pressing plate 30 rotates.

Buckle structure of the present utility model is applicable to the situation that the axis hole of great majority switch and socket fastens, its versatility Preferably.Moreover, buckle structure of the present utility model is without complicated and expensive components, it is only necessary to it is raw that injection can realize batch Produce, be therefore not required to higher cost and can realize producing.

By using buckle structure of the present utility model so that assemble convenient, it is not necessary to the training of specialty is with loaded down with trivial details Operation so that the reliability of assembling product is substantially improved, and drastically increases the production efficiency of product.

It is to be understood that, although this specification describes according to each embodiment, but the most each embodiment only comprises one Individual independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should will say Bright book can also form those skilled in the art permissible through appropriately combined as an entirety, the technical scheme in each embodiment Other embodiments understood.

The a series of detailed description of those listed above is only for the concrete of possible embodiments of the present utility model Illustrating, they are also not used to limit protection domain of the present utility model, all without departing from this utility model skill spirit made etc. Effect embodiment or change, as feature combination, split or repeat, within should be included in protection domain of the present utility model.
