Abstract
The utility model discloses a square plastic nut for an automobile. The square plastic nut comprises a plastic nut body. A cylindrical blind hole is arranged in the plastic nut body and matched with a self-tapping screw. The square plastic nut further comprises a rubber head for sealing, and the rubber head and the plastic nut body are fixedly connected with each other and is of an integrated structure. A square structure is further arranged at a joint of the plastic nut body and an automobile stamping part. The plastic nut body is further provided with a locking structure for locking the stamping part. Compared with the prior art, the square plastic nut is stable in structure, reliable to connect and good in tightness.
Description
Technical field
The utility model relates to a kind of automobile square plastic nut.
Background technique
Square nut is used for having on the automobile connection or the sealing of the structure of square hole, and to be used for the structure of sealing be to add sponge mat at nut to the square nut used of existing automobile at present, and this kind structure sponge mat easily comes off, and water-proof performance is poor.Plastic nut adopts polyoxymethylene (POM) material more simultaneously, and is fragile during detaching products.
The model utility content
The utility model provides a kind of automobile square plastic nut, adds the technical problem that sponge mat easily comes off and the nut water-proof performance is poor that sponge mat causes to solve in the prior art on the nut.
The technical solution of the utility model is as follows:
A kind of automobile square plastic nut, comprise the plastic nut body, described plastic nut body interior is provided with blind cylindrical hole, this blind cylindrical hole cooperates with tapping screw, also comprise the rubber head for sealing, described rubber head is fixedly connected with described plastic nut body, and is monolithic construction.
Preferably, described rubber head is directly to be dissolved in the rubber-wrapping structure that forms on the plastic nut, is that the technological method (such as quadric injection mould) by special type forms.
Preferably, described plastic nut body also is provided with the square structure that cooperates with sheet metal part with the automobile metal plate work joint, is used for installing the square hole sheet metal part of vehicle body.
Preferably, be provided with on the described plastic nut body for the locking mechanism of locking sheet metal part.
Preferably, described locking mechanism is buckle structure.
Preferably, described plastic nut body is PA6 plastic nut body.
Compared with prior art, the beneficial effects of the utility model are as follows:
The first, the rubber head of being located at this square plastic nut body head adopts rubber-wrapping structure, makes this square plastic nut have structural stability, good seal performance, and water-proof performance is good, connects reliably, and the advantage such as do not come off;
The second, square plastic nut body and rubber head are designed to monolithic construction, reduce the manual assembly cost, improve productivity effect;
Three, the plastic nut body adopts the PA6 plastic nut, compares with the POM plastic nut, and is not easy to crack during the dismounting product, in the working life of improving product, reduces maintenance cost.
Certainly, implement arbitrary product of the present invention and might not need to reach simultaneously above-described all advantages.
Description of drawings
Fig. 1 is the cross-sectional view that a kind of automobile of the utility model embodiment is used the square plastic nut;
Fig. 2 is the installation environment generalized section that a kind of automobile of the utility model embodiment is used the square plastic nut.
Embodiment
Below by preferred embodiment the technical solution of the utility model is described, but following embodiment can not limit protection domain of the present utility model.
Embodiment
As shown in Figure 1, a kind of automobile comprises plastic nut body 11 with square plastic nut 1, this plastic nut body main body is square, comprise that also rubber head 14 is fixedly connected with plastic nut body 11, and is monolithic construction for the rubber head 14 of sealing.A non-limitative example of rubber head can be by extraordinary technological method such as adopting quadric injection mould to form for directly being dissolved in the rubber-wrapping structure that forms on the plastic nut.In the present embodiment, rubber head 14 directly is dissolved on the plastic nut by quadric injection mould, has saved manual assembly man-hour, saves cost.And injection molded square plastic nut is monolithic construction, and this structure has structural stability, connect reliable firm, good seal performance, good waterproof performance, the advantage such as do not come off and need not assemble.
Plastic nut body 11 inside are provided with blind cylindrical hole 12, and this blind cylindrical hole 12 cooperates with tapping screw, are used for installing tapping screw.In the present embodiment, blind cylindrical hole 12 has drafting angle, in addition, also can not have drafting angle.
Plastic nut body 11 also is provided with square structure 13 with automobile square hole sheet metal part joint, also is provided with locking mechanism 15 below this square structure, is used for locking square hole sheet metal part.A non-limitative example of this locking mechanism can be buckle structure.
The using method of present embodiment square plastic nut during use, is put into sheet metal part 3 holes with square plastic nut 1 with reference to Fig. 2, then covers stationary platen spare 2, and the tapping screw spare 4 of packing into is afterwards realized connection and the locking of product.The rubber head 14 that is pressed into tapping screw spare 4 rear square plastic nuts 1 tightly is fitted on the sheet metal part 3, realizes water proofing property and the sealing of product.
The plastic nut bulk material can adopt PA6(nylon) material, the toughness of PA6 material is better than the POM(polyoxymethylene) material, and not fragile when making detaching products, thus the working life of prolongation square plastic nut.
Above embodiment only is used for illustrating content of the present utility model, and except above-mentioned mode of execution, the utility model also has other mode of execution, and all employings are equal to replaces or technological scheme that the equivalent deformation mode forms all drops in the protection domain of the present utility model.
