Abstract
The utility model relates to a novel assembly structure for the connection of a fiber-glass product fastener, comprising a fiber-glass product body (1) and an assembled nut (2) or a bolt (3). The utility model is characterized in that the assembly position of the fiber-glass product body (1) is provided with a boss (4) which is internally provided with an inner hole (4.1); the inside and the outside of the assembled nut (2) are both assembled with screw thread, wherein the external screw thread (2.1) is used for being assembled with the inner hole (4.1) of the boss (4), or the assembled bolt (3) is provided with two sections of external screw thread. The utility model is capable of eliminating the potential safety hazard during the productive process, increasing the production efficiency of the product, improving the smooth performance of the appearance of the product, decreasing the cost of the product under the normal exhaustion, thus providing convenience for the following assembly.
Description
(1) technical field
The utility model relates to a kind of assembly technique that is applied to the vehicle glass steelwork, especially relate between the automobile exterior spare and and vehicle body between mounting structure, belong to the vehicular spare parts technical field.
(2) background technology
The assembling form of existing vehicle glass steelwork adopts bolted connection through regular meeting, but all is that nut (or screw) is placed in the mould and this body by integral forming of glass fiber reinforced plastics product, shows as nut (or screw) pre-buried mode in the glass-felt plastic body.But this mode exists many deficiencies at aspects such as production efficiency, technological forming, reasonable structures, specifically, can be divided into the following aspects:
If 1 buries the boss excessive height of nut (or screw), boss bottom material stock is too much, tangible shrink mark can occur at the outside face of this position product;
If 2 builtin-nuts (or screw) need be placed on patrix, then there is the problem that dropped easily by gravity effect.If nut before matched moulds (or screw) drops, can seriously damage mould during matched moulds;
If the specification difference of 3 nuts, placement location mistake can cause mould impaired, there is very big potential safety hazard.
When 4, in-molded, gap between accessory on the mould and the nut (or screw) can cause the screw thread place of feed stream to nut (or screw), cause the screw thread of builtin-nut unclean, and be difficult to cleaning, if manner of cleaning up is improper even can destroy the coating or the screw thread itself of thread surface, thereby has influence on follow-up assembling;
If 5 half-blanks are scrapped, builtin-nut (or screw) is difficult to separate from body, has increased productive costs;
6, after product life stops,, can increase the difficulty of waste recovery because builtin-nut (or screw) is difficult to separate with the glass-felt plastic body.
(3) summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned original assembling form, a kind of potential safety hazard that can eliminate in the production process is provided, improve production efficiency of products, strengthen the exterior smooth fairing degree of product, reduce the cost under the product normal shrinkage, the novel mounting structure of fastener of fiberglass-reinforced product bonded assembly that offers convenience for the assembling in later stage.
The purpose of this utility model is achieved in that a kind of novel glass steelwork fastener bonded assembly mounting structure, comprise glass fiber reinforced plastics product body and the nut or the screw that are assembled, on described glass fiber reinforced plastics product body, there is the position of assembly relation to be provided with boss, be provided with endoporus in the boss, all be provided with screw thread inside and outside the nut that is assembled, outside thread is used for assembling with the endoporus of boss, and negative thread then assembles with other parts.The boss that is used for fixing this nut or screw is threaded to nut (or screw) in the endoporus of boss with special tool after the depanning at in-mold molding.
The purpose of this utility model also can be achieved in that a kind of novel glass steelwork fastener bonded assembly mounting structure, comprise glass fiber reinforced plastics product body and the nut or the screw that are assembled, on described glass fiber reinforced plastics product body, there is the position of assembly relation to be provided with boss, be provided with endoporus in the boss, the screw that is assembled has two sections outside threads, one section is used for realizing assembling with boss, and another section is used for realizing assembling with other parts.
Compare with the assembling form of existing builtin-nut, the utlity model has following characteristics:
1, guarantees the conformability of product wall thickness, avoided the appearance of product external surfaces shrink mark;
2, the quantity of nut (or screw) is many more, and the advantage of back fit is obvious further, pre-buried relatively mode, and it has increased the degree of utilization of mould and press, has promptly shortened the manufacturing cycle of product, has reduced productive costs;
3, eliminated the impaired hidden danger of mould in the formed product process;
4 if the assembling form of builtin-nut (or screw), mould need be made corresponding slide block and be used for setscrew nut (or screw), the utility model then only need come the deep hole of moulding assembling nut (or screw) to get final product with thimble, so the utility model has reduced the manufacture difficulty and the cost of mould;
If 5 half-blanks are scrapped, the nut (or screw) of back assembling can be removed and reuse, and has saved cost;
When 6, product life stopped the back waste recovery, rearmounted nut (or screw) was easy to separate with the glass-felt plastic body.
