Abstract

The utility model relates to a locking fastener of a vehicle for motor vehicles. The utility model comprises a bottom plate, pin columns and a middle fastener body, wherein both ends of the middle fastener body are respectively connected with the pin columns which are connected with the bottom plate. The utility model is characterized in that the width of one end of both of the two ends of the middle fastener body is larger than that of the other end; both sides of the middle part of the middle fastener body are provided with smooth curves which are dovetailed with curves arranged at both sides of an open cavity of a lock body, and the smooth curves are in interference fit with the curves arranged at both of the two sides of the open cavity of the lock body; the narrower end of the middle fastener body is provided with a circular arc chamfer; the middle fastener body is a flat plate body, and the middle fastener body can be a cylinder or an elliptical cylinder. The utility model is tightly matched with the lock body so that friction or impact noise between the utility model and the lock body is reduced and even eliminated.

Description

A kind of vehicle snap close

Technical field

The utility model relates to motor vehicle, relates in particular to a kind of vehicle snap close.

Background technology

Snap close is the significant components of vehicle side door locking device, generally is arranged in body side wall, contains locking mutually by mechanism's clamp, ratchet in sealing ring portion and the door lock, to reach the effect that the locking car door guarantees safety.

Existing lock catch of door lock has two kinds of forms usually:

As shown in Figure 1, a kind ofly formed by the rod iron bending for ring portion, linking to each other with base plate forms.

As shown in Figure 2, another kind is that ring portion is riveted by long intermediate plate 30 and two pins 2, and linking to each other with base plate 1 forms again.

As shown in Figure 3, these two kinds of snap closes in use all are that ring portion all is inclusive in the atrium 4 of lock body, though these two kinds of existing buckle structures are simple in structure, but, the atrium 4 of existing lock body diminishes toward interior camber line gradually because being opening, promptly, as shown in Figure 3, the upper and lower surface side of atrium 4 has curve 4a and curve 4b respectively, therefore, existing latch in buckle into atrium 4 after, snap close can not closely cooperate with atrium 4, even vehicle normal operating jolt can make snap close and lock body mutually string move, produce friction or impact noise, the prior art functional reliability is low.

Summary of the invention

The vehicle snap close that provides a kind of functional reliability high is provided the purpose of this utility model, to solve the problem that cooperates in the prior art closely, produces noise.

The vehicle snap close that the utility model adopted, comprise base plate, pin and middle button, the button two ends link to each other with pin respectively in the middle of described, and described pin is connected to base plate, it is characterized in that: the width of an end is greater than the width of the relative other end among the described middle button two ends.

The both sides, middle part of button are smooth curve in the middle of described.

The curve of described smooth curve and lock body atrium both sides matches.

The curve of described smooth curve and lock body atrium both sides is an interference fit.

The less end of button width is provided with circular arc chamfering in the middle of described.

Button is a platysome in the middle of described.

Button is cylinder or oval cylinder in the middle of described.

The beneficial effects of the utility model are: in the utility model, the width of an end is greater than the width of the relative other end among the middle button two ends, when the utility model buckles in the lock body, the this of middle button matched with the form that the past interior camber line gradually of the opening of atrium diminishes just by length and width degree to the short width state that buckles into, like this, the contact area of the both sides up and down of middle button and atrium, with respect to prior art, will be much bigger, also just meaning, the utility model cooperates tightr with lock body, normal operating the jolting of vehicle the moving possibility of both mutual strings is reduced, and has also just reduced mutual friction or impact noise.

The both sides, middle part of middle button are smooth curve, and match with the curve of lock body atrium both sides, have just improved the goodness of fit of the curve of middle button and atrium both sides, both are closely cooperated, and reduce to rub or impact noise.

When the curve of the smooth curve of the both sides, middle part of middle button and lock body atrium both sides is interference fit, after the utility model buckles into the lock body of plastics manufacturing, button in the middle of atrium then inwardly tightly blocks, realized seamless cooperation between the two, made between the two friction or impact noise complete obiteration.

Fig. 4 is the utility model structural representation.

The specific embodiment

With embodiment the utility model is described in further detail with reference to the accompanying drawings below:

Embodiment 1:

According to Fig. 4, the utility model comprises base plate 1, pin 2 and middle button 3, and this centre button 3 is a platysome, and middle button 3 two ends link to each other with pin 2 respectively, pin 2 is connected to base plate 1, and the width W l of an end is greater than the width Ws of the relative other end among middle button 3 two ends.

As shown in Figure 4, the both sides, middle part of middle button 3 are smooth curve 3a, 3b, and with reference to figure 3, this smooth curve 3a, 3b match with curve 4a, the 4b of lock body atrium 4 both sides respectively.

As shown in Figure 4, the less end of middle button 3 width is provided with circular arc chamfering 32, and in fact, the bigger end of middle button 3 width also is provided with circular arc chamfering 32.

According to Fig. 3 and shown in Figure 4, when using the utility model, the middle button 3 length and width degree in the utility model buckle into atrium 4 to short width, and smooth curve 3a and curve 4a match, smooth curve 3b and curve 4b match, and the utility model and lock body closely cooperate.

Embodiment 2:

The difference of present embodiment and embodiment 1 is: in an embodiment, curve 4a, the 4b of smooth curve 3a, 3b in the middle button 3 and lock body atrium 4 both sides is corresponding micro-interference fit.

Described same or similar as for other structure and using method and embodiment 1, repeat no more herein.

In the various embodiments described above, middle button 3 is a platysome, equally, middle button 3 also can be cylinder, oval cylinder or other shape, and, in the PROCESS FOR TREATMENT of reality, middle button 3 can be an integrative-structure with pin 2, for example, by plate material or cylinder material are bent, the die mould processing obtains the form in the utility model, the width at button 3 two ends was inconsistent in the middle of main points of the present utility model were, after middle button 3 buckled into atrium 4, this of middle button 3 matched with the form that the past interior camber line gradually of the opening of atrium 4 diminishes just by length and width degree to the short width state that buckles into, according to the above, this to those skilled in the art, can not need to pay creative work can implement, and repeats no more herein.
