Abstract
The utility model belongs to a kind of for car light screw and the structure of sealing ring cooperation of automobile lamp manufacturing field, it is connected between first connector and the second connector using screw, the screw sequentially passes through first connector and second connector, first connector, which is located at below the nut of the screw, is equipped with seal groove, the seal groove is arranged for one week along the screw rod of the screw, sealing ring is arranged in the seal groove, increase the triangle muscle of protrusion on the sealing bottom surface, the triangle muscle is arranged along the sealing ring border.The close contact for which solving sealing ring and seal groove seals, it is ensured that the air-tightness of lamps and lanterns.
Description
Technical field：
The utility model is related to automobile lamp manufacturing fields, and in particular to a kind of for screw and the knot of sealing ring cooperation
Structure.
Background technology：
The leakproofness of lamps and lanterns is one of important indicator of lamps and lanterns qualification, bolt structure be also at present common sealing structure it
One, bolt structure usually sets seal groove, and the sealing of lamps and lanterns is played in three's cooperation between seal groove and sealing ring and lamp body
Effect.
Current structure is sealing ring and seal groove is directly face matching relationship.It is coarse etc. when piece surface is there are overlap
Problem or the problem of assembling is bad when causing the unilateral stress of sealing ring, and face cooperation process window is small, can be amplified, and influence lamps and lanterns gas
Close performance causes lamps and lanterns seal failure.
The content of utility model
The utility model provides a kind of structure for the cooperation of car light screw and sealing ring, which solve sealing ring with it is close
The close contact sealing of sealing groove, it is ensured that the air-tightness of lamps and lanterns.
The basic technical scheme of the utility model is：It is connected between first connector and the second connector using screw, institute
It states screw and sequentially passes through first connector and second connector, first connector is located at the nut of the screw
Lower section is equipped with seal groove, and the seal groove arranges that sealing ring is arranged in the seal groove, institute for one week along the screw rod of the screw
Stating increases the triangle muscle of protrusion on sealing bottom surface, the triangle muscle is arranged along the sealing ring border.The technology makes
The triangle muscle of sealing ring and seal groove is obtained as line matching relationship, process window can effectively be increased by increasing line cooperation contact, be prevented
The whole airtight failure of lamp.First connector can be lamp body, and the second connector can be case ring etc..
The beneficial effects of the utility model are：
1. in terms of assembly technology：Increase the relation that line coordinates at one, increase the process window of part.
2. in terms of mold modification：Part increases feature, and mold modification is convenient and quick.
Description of the drawings
The application examples of the utility model is explained below in conjunction with the accompanying drawings.
Fig. 1 is the seal groove schematic diagram increased after triangle muscle.
Fig. 2 is the installation diagram of the utility model.
Specific embodiment
Shown in Fig. 1, increase the triangle muscle 1 of protrusion, 1 border of triangle muscle arrangement in 5 lower surface of seal groove, path is along close
Seal by region.
Fig. 2 is the installation diagram of the utility model.Connected between first connector 6 and the second connector 7 using screw 3
It connects, screw 3 sequentially passes through the first connector 6 and the second connector 7, and the first connector 6 is equipped with seal groove 5, and seal groove 5 is located at
Below the nut of screw 3, seal groove 5 arranges that sealing ring 4 is arranged in seal groove, 5 bottom of seal groove for one week along the screw rod of screw
Increase the triangle muscle 1 of protrusion on surface, triangle muscle 1 is arranged along sealing ring border.
Sealing ring 4 is directly face matching relationship with seal groove 5 in the prior art, and the triangle muscle of protrusion is added in this technology
1, triangle muscle 1 is arranged in 2 lower surface of seal groove, and the triangle muscle 1 for making sealing ring 4 and seal groove 5 is line matching relationship
A kind of scheme for implementing to provide to the utility model above is discussed in detail, for those of ordinary skill in the art,
According to the thought of the present embodiment, in specific embodiments and applications there will be changes.In conclusion this specification
Content should not be construed as the limitation to the utility model, and all any changes made according to the utility model design philosophy are all in this reality
Within new protection domain.
