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 the CD-ROM device field, particularly a kind of movement is pressed dish module shell fragment.
Background technology
Simultaneously referring to Fig. 1, Fig. 2, represent that a traditional inhalation type machine core presses dish module shell fragment, when its purpose is read dish for the video disc high speed rotating, the small movement parts can stressed very big situation under, shell fragment realizes that compressing video disc reads dish, protects that to levy video disc non-slip.As shown in Figure 1, this biography inhalation type machine core presses five metals parts mode that dish module shell fragment generally all adopts the structure more complicated realizing its reliability, but the component processing method more complicated, component costs is than higher.In addition, maybe be long because of reading the dish time, five metals shell fragment and the friction of plastic cement gland projection with the wearing and tearing of plastic cement gland projection, are read the dish bad hidden danger thereby stay.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of movement to press dish module shell fragment, can improve and read the dish reliability.
For solving above technical matters, technical scheme provided by the invention is: a kind of movement is pressed dish module shell fragment, comprises the sheet material that plastic material is processed; Said sheet material comprises diapire; Said diapire is provided with rear side installation portion and preceding side pressure dish portion, and the upwards vertical respectively bending of the left and right side of said rear side installation portion forms the left and right side flanging; Said left and right side flanging is bending laterally respectively, forms left and right cross break limit.
More excellent ground, said left and right cross break limit extend to front side and rear side simultaneously, form the hangers of pressing the mounting hole on the dish arm to cooperate with movement, press on the dish arm said movement is pressed dish module shell fragment be installed in said movement.
More excellent ground, said rear side installation portion and said preceding side pressure dish portion are positioned on the same plane.
More excellent ground becomes step-like between said rear side installation portion and the said preceding side pressure dish portion.
More excellent ground is the left-right symmetric structure.
Compared with prior art, it is that plastic sheet is processed that movement of the present invention is pressed dish module shell fragment, and cooperating the friction of plastic cement gland projection is plastic cement and plastic cement friction, makes that plastic cement gland projection is not easy to wear and tear, and can realize thus than the higher dish unfailing performance of reading.This shell fragment need not punching press and injection moulding, and production technology is simple, and volume is little, and cost is low, and novelty is bigger, has application promise in clinical practice.
Description of drawings
Fig. 1 is the structural representation that existing movement is pressed dish module shell fragment;
Fig. 2 is the structural representation that existing movement is pressed dish module shell fragment;
Fig. 3 is the structural representation that movement of the present invention is pressed dish module shell fragment;
Fig. 4 is the assembling synoptic diagram that movement of the present invention is pressed dish module shell fragment.
Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better, the present invention is done further detailed description below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 3, represent the structure of movement pressure dish module shell fragment (hereinafter to be referred as a shell fragment) preferred embodiment of the present invention.The left-right symmetric structure of this shell fragment for adopting plastic sheet to process, this sheet material comprises diapire 1, is provided with rear side installation portion 5 and preceding side pressure dish portion 2 above, the wherein upwards vertical respectively bending of the left and right side of rear side installation portion 5 forms left and right side flanging 6,4; And left and right side flanging 6,4 bending once more laterally respectively forms left and right cross break limit 7,3.
As shown in Figure 3, rear side installation portion 5 is positioned on the same plane with preceding side pressure dish portion 2.Also can continue to use the prior art characteristic, promptly become step-like between rear side installation portion 5 and the preceding side pressure dish portion 2.More excellent ground, left and right cross break limit 7,3 extend to front side and rear side simultaneously, form the hangers of pressing the mounting hole on the dish arm to cooperate with movement, press on the dish arm this movement is pressed dish module shell fragment be installed in movement.
Referring to Fig. 4, the fit that movement is pressed dish module shell fragment is shown.The hangers that left and right cross break limit 6,3 forms presses the mounting hole 9,10 on the dish arm 8 to cooperate with movement, can press dish module shell fragment to be installed in movement movement easily and press on the dish arm 8.
The described plastic sheet shell fragment of present embodiment need not punching press and injection moulding, and production technology is simple, and volume is little, and cost is low, and certain advance is arranged.Because of cooperating with the projection of plastic cement gland, shell fragment is not easy wearing and tearing, so can realize than the higher dish unfailing performance of reading.
Only be preferred implementation of the present invention below, should be pointed out that above-mentioned preferred implementation should not be regarded as limitation of the present invention, protection scope of the present invention should be as the criterion with claim institute restricted portion.For those skilled in the art, do not breaking away from the spirit and scope of the present invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
