Embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail.
Easily understand, according to the technical solution of the utility model, do not changing under connotation of the present utility model, one of ordinary skill in the art can propose various structures mode and the implementation that can mutually replace.Therefore, following embodiment and accompanying drawing are only the exemplary illustrations to the technical solution of the utility model, and should not be considered as of the present utility model all or be considered as the restriction of technical solutions of the utility model or restriction.
The orientation terms such as the up, down, left, right, before and after of mentioning in this manual or may mentioning, front, the back side, top, bottom are to define with respect to the structure shown in each accompanying drawing, they are relative concepts, therefore likely can correspondingly change according to its diverse location of living in, different use state.So, these or other orientation term should be interpreted as to restricted term yet.
Refer to Fig. 1, the semi-finished product of the utility model beak type fastener 1 comprise a head 4, neck 5, and shoulder 6, elastic arm 9, extracts anti-bias 7 and two and inserts anti-bias 8.Described head 4 is flange shape and is positioned at the top of described beak type fastener, described neck 5 is for thinner vertically extending structure and be connected to described head 4 belows, what the below of described neck 5 connected is the described shoulder 6 that is also flange shape, and what below described shoulder 6, connect is two described elastic arms 9.Described two elastic arms 9 are You Yi space between beak shape and two elastic arms 9, that is to say that two elastic arms 9 have certain distance apart, to guarantee that resiliently deformable can occur two elastic arms in the horizontal direction.Each elastic arm 9 include the joint 91 that is connected with shoulder 6 and joint 91 to downward-extension and the outside arc portion 92 of projection, space length between these two joints 91 is less, space length between two arc portions 92 is greater than two distances between joint 91, and the end of the arc portion 92 of two elastic arms 9 is connected to each other.The shape of the corresponding stamping holes of the outer shape of elastic arm 9, it can be cylindric or other shapes and be beneficial to coordinate with panel beating installation.Describedly extract anti-bias 7 and extend in vertical direction, it is positioned at the space in the middle of two elastic arms 9, described in the one end of extracting anti-bias 7 be connected to the below of shoulder 6, arc portion 92 ends of the other end and two elastic arms 9 link together.Anti-bias 8 of described each insertion protrudes out to the direction of extracting anti-bias 7 that is positioned at the middle space of two elastic arms in the form of sheets and all, and extracts anti-bias 7 certain distances described in distance.
Thereby the shoulder that the semi-finished product of beak type fastener 1 make fastener 1 through single injection-molded has again been coated respectively softer plastic material and above shoulder 6, has formed an encapsulate and take on 10 and below shoulder, formed pair of lamina seal ring 11 in both sides 6 Shang Xia.
Referring to Fig. 3, is that the utility model beak type fastener 1 is not also fixed on the schematic diagram on vehicle body sheet metal 3 by inside gadget or exterior trimming parts 2.Neck 5 shapes of the corresponding beak type of attachment face 20 fastener 1 of described inside gadget or exterior trimming parts 2 are provided with the breach 21 of end opening one by one, and the opening size of described breach 21 is less than breach central diameter.Described plates of automobile 3 is provided with a circular hole 31, and the diameter of described through hole 31 is less than the distance between arc portion 92 outer side surfaces of 1 two elastic arms 9 of beak type fastener.
Refer to Fig. 4, when installing, the neck 5 of beak type fastener 1 is snapped in the breach 21 of described inside gadget or exterior trimming parts 2, because breach 21 opening sizes are less than breach central diameter, therefore neck 5 can firmly be stuck in breach 21 can not deviate from the horizontal direction, and the attachment face 20 of inside gadget or exterior trimming parts 2 is clipped in the middle of the encapsulate shoulder 10 and head 4 of beak type fastener 1 firmly, thereby make beak type fastener 1 fixing with inside gadget or exterior trimming parts 2.
The interior insertion of through hole 31 by from two elastic arms 9 of beak type fastener 1 to panel beating 3, two elastic arms 9 of described beak type fastener 1 pass through hole 31 because resiliently deformable can occur inwardly to shrink in through hole 31 inwall extruding arc portions 92, owing to being provided with, insert anti-bias 8, in the process of inserting, rostriform a certain elastic arm 9 is supported at most and is extracted on anti-bias 7 when contraction deformation to greatest extent, can further to another elastic arm 9 directions, further not be out of shape, can not insert when guaranteeing that beak type fastener 1 inserts askew.Finally, joint 91 is just in time housed in through hole 31, and arc portion 92 flicks and restores to the original state panel beating 3 is just in time clipped between double-layer seal ring 11 and arc portion 92, thereby beak type fastener 1 is fixed on inside gadget or exterior trimming parts 2 on panel beating 3.
Described beak type fastener 1 is when panel beating 3 is extracted, even if the component skewness of substantially horizontal when user operates, owing to having vertical extract anti-bias 7, can guarantee that it can not warp and can extract smoothly.
Through test determination, it is 1:5 with the ratio of the power of extracting from panel beating 3 that described beak type fastener 1 inserts panel beating 3.
Beak type fastener of the present utility model has the elastic arm of beak type structure, can make the ratio of insertion force and withdrawal force reach 1:5 left and right, realize the requirement of low insertion force and high withdrawal force, because insertion force requires low, make convenient this fastener of installing of user, because withdrawal force requirement is high, make this fastener fixing firm again.
The utility model fastener substitutes sponge mat with the formed encapsulate shoulder of encapsulate technique and double-layer seal ring and realizes water-tight, can realize full-automatic production, has fully improved manufacturing efficiency, and has reduced cost of production.
Above embodiment is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the scope of the invention; can also make a variety of changes and modification; therefore all technological schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
