Abstract
The invention relates to the field of a CD-ROM (Compact Disc Read-Only Memory) driver, and particularly discloses an elastic sheet for a machine core disc-pressing module. The elastic sheet comprises a sheet made of plastic materials; the sheet comprises a bottom wall; a rear mounting part and a front disc-pressing part are arranged on the bottom wall; left and right sides of the rear mounting part are respectively bent upward vertically, thereby forming left and right side bent edges; and the left and right side bent edges are respectively bent outward, thereby forming left and right transversal bent edges. The elastic sheet for the machine core disc-pressing module provided by the invention is made of plastic sheet materials, and friction of a matched plastic gland lug is plastic-plastic friction, thereby being difficult to abrade the plastic gland lug and realizing higher disc-reading reliability.
Description
Technical field
The present invention relates to CD-ROM device field, particularly a kind of elastic sheet for machine core disc-pressing module.
Background technology
Simultaneously see Fig. 1, Fig. 2, represent a traditional inhalation type machine core pressure dish module spring plate, its object is video disc High Rotation Speed when reading dish, and small movement parts can not in stressed very large situation, and shell fragment realizes compressing video disc and reads dish, ensures that video disc is non-slip.As shown in Figure 1, this biography inhalation type machine core pressure dish module spring plate generally all adopts the five metals parts mode of complicated structure to realize its reliability, but component processing method more complicated, component costs is higher.In addition, may be long because of reading the dish time, five metals shell fragment and plastic cement gland projection rub, and by the wearing and tearing of plastic cement gland projection, thus stay and read dish bad hidden danger.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of elastic sheet for machine core disc-pressing module, can improve and read dish reliability.
For solving above technical matters, technical scheme provided by the invention is: a kind of elastic sheet for machine core disc-pressing module, comprises the sheet material that plastic material is made; Described sheet material comprises diapire; Described diapire is provided with rear side installation portion and pressure dish portion, front side, and the left and right side of described rear side installation portion, respectively to upper vertical bending, forms left and right side flanging; Described left and right side flanging, respectively to outer lateral buckling, forms left and right cross break limit.
More preferably, described left and right cross break limit extends to front side and rear side simultaneously, forms the hangers coordinated with the mounting hole on machine core disc-pressing arm, to be arranged on described machine core disc-pressing arm by described elastic sheet for machine core disc-pressing module.
More preferably, described rear side installation portion and described front side press dish portion in the same plane.
More preferably, stepped between described rear side installation portion and pressure dish portion, described front side.
More preferably, be bilateral symmetry.
Compared with prior art, elastic sheet for machine core disc-pressing module of the present invention is that plastic sheet is made, and the friction coordinating plastic cement gland projection is plastic cement and plastic cement friction, makes plastic cement gland projection be not easy to wear and tear, and can realize thus higher reading dish unfailing performance.This shell fragment is without the need to punching press and injection moulding, and production technology is simple, and volume is little, and cost is low, and novelty is comparatively large, has good application prospect.

Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
See Fig. 3, represent the structure of elastic sheet for machine core disc-pressing module of the present invention (hereinafter referred to as a shell fragment) preferred embodiment.This shell fragment is the bilateral symmetry adopting plastic sheet to make, and this sheet material comprises diapire 1, and be provided with rear side installation portion 5 and pressure dish portion 2, front side above, wherein the left and right side of rear side installation portion 5 is respectively to upper vertical bending, forms left and right side flanging 6,4; And left and right side flanging 6,4 bends again respectively to outside, form left and right cross break limit 7,3.
As shown in Figure 3, rear side installation portion 5 and front side press dish portion 2 in the same plane.Also prior art feature can be continued to use, i.e. stepped between rear side installation portion 5 and pressure dish portion 2, front side.More preferably, left and right cross break limit 7,3 extends to front side and rear side simultaneously, forms the hangers coordinated with the mounting hole on machine core disc-pressing arm, to be arranged on machine core disc-pressing arm by this elastic sheet for machine core disc-pressing module.
See Fig. 4, the assembling mode of elastic sheet for machine core disc-pressing module is shown.The hangers that left and right cross break limit 7,3 is formed coordinates with the mounting hole 9,10 on machine core disc-pressing arm 8, can be arranged on machine core disc-pressing arm 8 by elastic sheet for machine core disc-pressing module easily.
Plastic sheet shell fragment described in the present embodiment is without the need to punching press and injection moulding, and production technology is simple, and volume is little, and cost is low, has certain advance.Be not easy to wear and tear because shell fragment coordinates with the projection of plastic cement gland, therefore can realize higher reading dish unfailing performance.
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
