A kind of sliding support that is used for the automobile lamp fixture mounting groove mouth
Technical field:
The present invention relates to automobile manufacturing field, be specifically related to a kind of sliding support that is used for the automobile lamp fixture mounting groove mouth.
Background technology:
Automobile lamp is all bigger, general all on four angles of automobile lamp, be provided with four notches are installed, be provided with four installing holes at the corresponding site of body of a motor car, but because the problem of manufacturing process, cooperate between light fixture and the vehicle body to exist gap and face poor, therefore be not easy to guarantee the precision of installing.
Summary of the invention:
The object of the present invention is to provide a kind of sliding support that is used for the automobile lamp fixture mounting groove mouth that can overcome above defective.
To achieve these goals, technical scheme of the present invention is as follows: a kind of sliding support that is used for the automobile lamp fixture mounting groove mouth, it comprises pin, the cross section that it is characterized in that this pin is a square, these foursquare wherein two these foursquare two sections inscribe circularity substitutions of diagonal angle, the bottom of pin is provided with the first rectangle baffle plate, the top of this pin is provided with second baffle, the width of second baffle is greater than the width of the first rectangle baffle plate, the length of the first rectangle baffle plate and second baffle is all greater than the width of the first rectangle baffle plate, second baffle is provided with two wing formula prerotation vanes corresponding to two sections inscribe circular arcs of pin place, and the outside of this wing formula prerotation vane is upturned.Also be provided with the pre-determined bit pin that raises up at second baffle.
Sliding support of the present invention is installed in the automobile lamp fixture mounting groove mouth, can be by the slip of sliding support in the automobile lamp fixture mounting groove mouth, the fit clearance and the face that guarantee light fixture and vehicle body are poor, and utilize the pre-determined bit pin to guarantee that this sliding support and vehicle body are in desirable mounting center position all the time.The invention has the advantages that simple in structure, easy to adjust, dependable performance and can be used in the installation of various light fixtures.

The specific embodiment:
Below in conjunction with drawings and Examples the present invention is elaborated.
It comprises pin 1, the cross section that it is characterized in that this pin 1 is a square, these foursquare wherein two diagonal angles substitute with these foursquare two sections inscribe circular arcs 2, the bottom of pin 1 is provided with the first rectangle baffle plate 3, the top of this pin 1 is provided with second baffle 4, the width of second baffle 4 is greater than the width of the first rectangle baffle plate 3, the length of the first rectangle baffle plate 3 and second baffle 4 is all greater than the width of the first rectangle baffle plate 3, second baffle 4 is provided with two wing formula prerotation vanes 5 corresponding to two sections inscribe circular arc 2 places of pin, and the outside of this wing formula prerotation vane 5 is upturned.Also be provided with the pre-determined bit pin 6 that raises up at second baffle 4.
Automobile lamp is provided with installs notch 7, and this installation notch 7 is a rectangle, and this length that notch 7 is installed is greater than width.The square length of side of pin 1 is slightly less than the width that notch 7 is installed, but the foursquare catercorner length of pin 1 should be greater than the width that notch 7 is installed, the width of this first rectangle baffle plate 3 is less than the width that notch 7 is installed, the length of the first rectangle baffle plate 3 is greater than the width that notch 7 is installed, the width of second baffle 4 is greater than the width that notch 7 is installed, and the height of pin 1 is greater than the height that notch 7 is installed.The outside of automobile lamp fixture mounting groove mouth 7 is provided with the outstanding straight-flanked ring 8 of a circle, and the spacing on these straight-flanked ring 8 width equals or be slightly larger than the length of second baffle 4, but less than the diagonal of second baffle 4.
During installation, the width of the first rectangle baffle plate 3 of this sliding support is aimed at the width that notch 7 is installed, sliding support is filled in installation notch 7, make win rectangle baffle plate 3 and second baffle 4 lay respectively at the both sides that notch 7 is installed, rotate this sliding support along the direction of wing formula prerotation vane 5 perks then, because wing formula prerotation vane 5 is corresponding with two sections inscribe circular arcs 2 of pin, so can rotate smoothly, when second baffle 4 is run into the straight-flanked ring of giving prominence in installation notch 7 outsides 8, because the outside of wing formula prerotation vane 5 is upturned, guide this second baffle 4 to cross this outstanding straight-flanked ring 8, when the length that turns to the first rectangle baffle plate 3 faces toward the width that notch 7 is installed, foursquare diagonal turned over the circular arc portion of pin 1, owing to greater than the width that notch 7 is installed, therefore can not continue smooth rotation.At this moment, the length of the first rectangle baffle plate 3 faces the width that notch 7 is installed, and the length of the length of the first rectangle baffle plate 3 and second baffle 4 is all greater than the width that notch 7 is installed, this sliding support just is stuck in have been installed in the notch 7, but this sliding support can slidably reciprocate in notch 7 is installed and adjust the position of light fixture with respect to vehicle body, thereby it is poor to reach fit clearance and the face adjusted between light fixture and the vehicle body.Second baffle is provided with the pre-determined bit pin can guarantee that sliding support and vehicle body keep theoretical installation site constant.
Obviously, those of ordinary skill in the art can make various modifications and distortion to sliding support of the present invention under the situation that does not exceed the described scope of claim, the structural design that comprises the slip round pin, the design of wing formula prerotation vane, the design of pre-determined bit pin and size of profile or the like.Therefore, if to various modifications of the present invention and modification in appended claim scope, then the present invention includes these modifications and modification.
