Abstract
The utility model discloses a car trim prevented from shrinking in injection molding. The car trim comprises a body, at least two screw studs used for being matched with screws and fixing the body to a car sheet metal part are arranged on the body at intervals, the screw studs are provided screw holes, threads are arranged in the screw holes, annular grooves are formed in the connecting positions of the screw studs and the body, the diameter of the upper end faces of the annular grooves is larger than that of the lower end faces of the annular grooves, and the height between the bottom ends of the annular grooves and the bottom end of the body is consistent with the height between the bottom ends of the screw holes and the bottom ends of the body. The car trim has the advantages that the thickness of walls at the connecting positions of the screw studs and the body is reduced, and the connecting positions of the screw studs and the body are prevented from shrinking in the injection molding.
Description
Technical field
The utility model relates to a kind of car trim, especially relates to a kind of car trim shrinking while avoiding injection moulding.
Background technology
Existing car trim is in order to be fixedly connected with automobile metal plate work; conventionally can be provided with such structure: mounting hole is set on automobile metal plate work; on car trim, be provided with screw pole, in screw pole, be provided with screw thread, and be threaded with screw pole through mounting hole with a screw.But due to Shooting Technique, the common car trim with screw pole, because the wall thickness of screw pole and ornamental trimming junction is excessive, causes this car trim to occur the phenomenon of shrinking when injection moulding.
Summary of the invention
It is little that technical problem to be solved in the utility model is to provide a kind of screw pole root wall thickness, the car trim shrinking in the time of can avoiding injection moulding.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of car trim shrinking while avoiding injection moulding, comprise main body, in described main body, be arranged at intervals with at least two for described main body being fixed on to the screw pole on automobile metal plate work with screw fit, described screw pole has screw, in described screw, be provided with screw thread, the junction of described screw pole and described main body is provided with annular groove, the upper surface diameter of described annular groove is greater than the lower surface diameter of described annular groove, the bottom of described annular groove is consistent apart from the height of main body bottom with the bottom of described screw apart from the height of main body bottom.
The upper surface of described annular groove and the vertical distance of lower surface are 1/2nd of main body wall thickness.
In described main body, be provided with the screw pole described in four.
The outer setting of described annular groove has annular reinforcing member, and described reinforcing member is fixedly connected with described screw pole by four road reinforced ribs.
Compared with prior art, the junction that the utility model has the advantage of screw pole and main body is provided with annular groove, the upper surface diameter of annular groove is greater than the lower surface diameter of annular groove, the bottom of annular groove is consistent apart from the height of main body bottom apart from the height of main body bottom and the bottom of screw, this structure has reduced the wall thickness of screw pole and main body junction, and while having avoided injection moulding, shrink in the junction of screw pole and main body;
When the upper surface of annular groove and the vertical distance of lower surface are that two of main body wall thickness/for the moment, in the time of can avoiding injection moulding, shrink in the junction of screw pole and main body;
While being provided with four screw poles in main body, main body can firmly be fixed on automobile metal plate work;
When the outer setting of annular groove has annular reinforcing member, when reinforcing member is fixedly connected with screw pole by four road reinforced ribs, increased the firm degree of screw pole, make not easy fracture of screw pole.
Accompanying drawing explanation
Fig. 1 is part sectional view of the present utility model;
Fig. 2 is the partial enlarged drawing of A part in Fig. 1;
Fig. 3 is block diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Embodiment: as shown in the figure, a kind of car trim shrinking while avoiding injection moulding, comprise main body 1, in main body 1, be arranged at intervals with at least two for main body 1 being fixed on to the screw pole 2 on automobile metal plate work with screw fit, screw pole 2 has screw 3, in screw 3, be provided with screw thread, screw pole 2 is provided with annular groove 4 with the junction of main body 1, the upper surface diameter of annular groove 4 is greater than the lower surface diameter of annular groove, and the bottom of annular groove 4 is consistent apart from the height of main body 1 bottom apart from the height of main body 1 bottom and the bottom of screw 3.
In the present embodiment, the upper surface of annular groove 4 and the vertical distance of lower surface are 1/2nd of main body 1 wall thickness, and in the time of can avoiding injection moulding, shrink in the junction of screw pole and main body.
In the present embodiment, be provided with four screw poles 3 in main body 1, main body 1 can firmly be fixed on automobile metal plate work.
In the present embodiment, the outer setting of annular groove 4 has annular reinforcing member, and reinforcing member is fixedly connected with screw pole 2 by four road reinforced ribs, has increased the firm degree of screw pole 2, makes not easy fracture of screw pole 2.
During use, reduced the wall thickness of screw pole 2 with main body 1 junction, while having avoided injection moulding, screw pole 2 shrinks with the junction of main body 1.
Claims (4)
1. the car trim shrinking while avoiding injection moulding, comprise main body, in described main body, be arranged at intervals with at least two for described main body being fixed on to the screw pole on automobile metal plate work with screw fit, described screw pole has screw, in described screw, be provided with screw thread, the junction of the screw pole described in it is characterized in that and described main body is provided with annular groove, the upper surface diameter of described annular groove is greater than the lower surface diameter of described annular groove, the bottom of described annular groove is consistent apart from the height of main body bottom with the bottom of described screw apart from the height of main body bottom.
