Description

Rolling curtain cup stand
Technical Field
The invention relates to a cup stand, in particular to a roller shutter cup stand, and belongs to the field of injection molding materials.
Background
The cup stand is the common accessory among the automotive interior spare, and its effect is used for placing articles such as drinking cup, mineral water bottle, for the convenience that increases roll up curtain cup stand and use, travelling process plays the fixed action to its built-in thing to the travelling of car.
The rolling curtain cup stand realizes the closing and opening of the opening on the cup bracket by sliding the cup cover. However, the roller shutter type cup cover has a large freedom of movement, so that a sufficient gap is left between the sliding groove of the cup support and the cup cover in sliding fit, otherwise, the sliding friction between the local position of the cup cover and the sliding groove is too large or is blocked, otherwise, the cup cover slides under the action of self inertia due to the too large sliding gap, so that an opening in the cup support cannot be effectively closed, and particularly, the cup cover slides under the conditions of vehicle running, vehicle acceleration or braking along with the fluctuation of a road surface, and the like, so that the service life of the roller shutter cup support is short, and the conditions occur in use.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the roller shutter cup stand which is high in strength, not easy to break and long in service life.
The purpose of the invention is realized by the following technical scheme: a rolling shutter cup stand comprises a main body made of a PC/ABS alloy material and a PtCu alloy film coated on the surface of the main body.
