The utility model discloses a fastening which relates to a connection component which connects the two parts into a whole. The fastening comprises an elastic hook which is an extending part from the cottage grafting components (10), moreover, the number of the elastic hook is two, and the elastic hooks (11,12) are provided in uniformly-spaced way along the width direction of the slot (21) which is opened on the fixed parts (20), and forms a PI shape with the cottage grafting components (10). The beneficial effects of the utility model are the following: the fastening makes the connection between the cottage grafting components and the fixed parts more stable; the fastening has certain tolerance, so that can decrease the demand for the manufacturing precision of moulds, and can be favor of decreasing the production cost of the fastening; the scope of the elastic deformation is big, the elastic hook is not easy to be broken, and the fastening can be assembly and disassembly repeatedly.
Description
Technical field
The utility model relates to a kind of connector element that two parts are connected as one.
Background technique
Fastener is a kind of connector element commonly used, has especially obtained utilization widely in the production of various household electric appliance.Fastener relates to plug component and fixed component, plug component and fixed component adopt plastic material more, plug component has an elasticity and colludes body, then offer on the fixed component for this elasticity and collude the slot that body inserts, under the effect of slot cell wall, elasticity is colluded body and is bent in the grafting process, and the back elasticity that puts in place of pegging graft is colluded the body resilience and resetted, the terminal surface that elasticity is colluded body is stuck on the inner actinal surface of slot, thereby realizes being connected and fixed between insertion parts and fixed component.At present, collude the shape of body according to elasticity and distinguish, common fastener can be divided three classes, i.e. loop fasteners, monolateral fastener and spherical fastener.For a long time, on the household appliances of television set one class, adopt monolateral fastener mostly, connect advantage closely though brought into play it, comparing screw is right after and assembles quick, with low cost with other modes of being right after, but the monolateral fastener tolerance of this kind is poor, it is high that die size is required, because of being subjected to the restriction of factors such as mould manufacturing, material behavior, the often actual fastener of making does not reach the designing institute desired effects.Loop fasteners and the same existence of the spherical fastener defective similar to monolateral fastener.
The model utility content
Technical problem to be solved in the utility model provides a kind of fastener, and this fastener not only makes the connection between plug component and the fixed component more firm, and has certain tolerance.Thereby can reduce accuracy of manufacturing requirement to production mould.
The technological scheme that its technical problem that solves the utility model adopts is: fastener of the present utility model has by the extended elasticity of plug component and colludes body, it is characterized in that: the quantity that described elasticity is colluded body is two, these two elasticity are colluded body and are provided with at interval along the width direction that is opened in the slot on the fixed component, and form the π shape with the body of plug component.
In technique scheme, described two elasticity are colluded body and can be preferably be symmetrical arranged along the vertical center line of slot.
After taking technique scheme, collude body by two elasticity and bear pulling force simultaneously, so compare with monolateral fastener, its pulling force that can bear is bigger, makes the connection between plug component and the fixed component more firm; Resiliently deformable is transformed into symmetrical two sides from single face, and deformation band strengthens, so have certain tolerance.
As improvement of the technical scheme, for further strengthening the tolerance of fastener, described two elasticity are colluded the terminal surface of body with respect to slot inner port surface tilt.
The beneficial effects of the utility model are to make the connection between plug component and the fixed component more firm; Have certain tolerance, therefore can reduce accuracy of manufacturing requirement, thereby help reducing the manufacturing cost of fastener production mould; Regime of elastic deformation is bigger, and elasticity is colluded not easy-rupturing of body, and fastener can repeat dismounting.
Description of drawings
This specification comprises following three width of cloth accompanying drawings:
Fig. 1 is the structural representation of the utility model fastener;
Fig. 2 is the insertion process schematic representation of the utility model fastener;
Fig. 3 adopts the plug component of the utility model fastener and the Placement schematic representation between the fixed component.
Component, position and numbering among the figure: plug component 10, elasticity are colluded body 11, elasticity is colluded body 12, terminal surface 13, terminal surface 14, fixed component 20, slot 21.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1, fastener of the present utility model, have by plug component 10 extended elasticity and collude body, the quantity that described elasticity is colluded body is two, these two elasticity are colluded body 11,12 and are provided with at interval along the width direction that is opened in the slot 21 on the fixed component 20, and form the π shape with the body of plug component 10.Described elasticity is colluded body 11,12 and can be preferably be symmetrical arranged along the vertical center line of slot 21.
With reference to Fig. 3, for the described elasticity of tolerance that further strengthens fastener is colluded the terminal surface 13,14 of body 11,12 with respect to slot 21 inner port surface tilt.Be to reduce in the grafting process firmly, and after grafting, plug component 10 can easily be unloaded from fixed component 20, described elasticity is colluded between the terminal surface 13,14, outer surface of body 11,12 and is rounded down.
Compare with traditional monolateral fastener, fastener of the present utility model has following characteristics:
One, connection is firm
Collude body by two elasticity and bear pulling force simultaneously, its pulling force that can bear is bigger, make between plug component 10 and the fixed component 20 be connected more firm;
Two, regime of elastic deformation is bigger
The resiliently deformable of plastics has certain scope, and the elasticity that overruns is colluded body and will be ruptured, and causes fastener to damage.Regime of elastic deformation is subjected to elasticity to collude body length to restrict, and is long then do not have intensity after cooperating if the elasticity of monolateral fastener is colluded body, if too short then amount of deformation is very little, be out of shape when big elasticity and collude body and easily rupture from root.And the distortion that fastener of the present utility model colludes elasticity body is transformed into the two sides of symmetry from single face, and deformation band strengthens naturally, and elasticity is colluded body 11,12 difficult fractures in the insertion process, and fastener can repeat dismounting.
Three, tolerance is strong
Monolateral fastener matches with plug component 10, facing directly of fixed component 20, height dimension to the fitting surface of plug component 10, fixed component 20 has higher requirement, otherwise can cause both connections not tight, even can give birth to elasticity and collude body and can't insert the phenomenon that puts in place.And in fastener of the present utility model, can make elasticity collude the terminal surface 13,14 of body 11,12 with respect to slot 21 inner port surface tilt, reducing the height dimension precision of plug component 10, fixed component 20 fitting surfaces, and can not have influence on the tightness of its connection.
It is pointed out that top described principles more of the present utility model that just explain through diagrams, because the those of ordinary skill in constructed field is easy to carry out on this basis some modifications and change.Therefore, this specification be not be the utility model to be confined to shown in and in described concrete structure and the Applicable scope, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
