Abstract
The utility model discloses a bottom plate for a DVD (Digital Video Disk), which comprises a body, wherein circular grooves and an auxiliary groove that have the same depth are formed on the body, the circular grooves are communicated by the auxiliary groove, the diameter of each circular groove is greater than the width of the auxiliary groove, and bolting holes are formed at the centers of the bottoms of the circular grooves. According to the bottom plate for the DVD player, while bolt heads are sunk into the circular grooves completely, the width of the auxiliary groove is reduced, so that a larger space is provided for the position design of a swinging arm structure, and the difficulty in processing and assembling the whole DVD player is reduced. In addition, a structure that the circular grooves are communicated by the auxiliary groove avoids deformation of other parts caused in the circular groove manufacturing process, and the planeness of the whole bottom plate for the DVD player is ensured.
Description
Technical field
The utility model relates to DVD, relates in particular to a kind of DVD base plate.
Background technology
The DVD base plate is the power supporting parts of each swing arm structure in the DVD, provides protection for the DVD player core simultaneously.Existing DVD base plate can stamp out groove, at bottom portion of groove design bolt connecting hole, avoid bolt to install after, bolt head protrudes whole too high, affects the global design of DVD integral body; But for bolt head can sink in the groove fully, the width design of groove must be greater than the external diameter of bolt head; Wide recess width forces the positional precision of swing arm structure to improve, and has increased difficulty of processing; And it is plated steel sheet that existing DVD base plate adopts SECC(usually) make through Sheet Metal Forming Technology, its corrosion stability and japanning are not very good.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of DVD base plate, and it can reduce the width of groove in the installation that guarantees bolt, reduce its difficulty of processing, reduces processing cost.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of DVD base plate comprises body, is provided with the identical circular groove of the degree of depth and secondary groove at body, is communicated with by secondary groove between the described circular groove; The diameter of described circular groove is greater than the width of secondary groove; Center in the circular groove bottom is provided with bolt connecting hole.
The design of above-mentioned DVD base arrangement when having guaranteed that bolt head sinks to circular groove fully, has reduced the width of secondary groove, for the Position Design of swing arm structure provides larger space, has reduced processing, the assembling difficulty of whole DVD; The distortion at other positions that the structure that is communicated with circular groove by secondary groove has simultaneously caused when also having avoided only making circular groove has guaranteed the flatness of whole DVD base plate.
Preferably, the diameter of described circular groove greater than with the external diameter of the adaptive bolt head of bolt connecting hole, the width of described secondary groove less than with the external diameter of the adaptive bolt head of bolt connecting hole.
Preferably, the maturation process such as this DVD base plate can be sheared by sheet material, bending are made into integrative-structure, and manufacture difficulty is little; Preferably, this DVD base plate is that SGCC(is the galvanizing steel plate) material, to improve corrosion stability and the japanning of DVD base plate.
Beneficial effect: the DVD base plate that the utility model provides, when having guaranteed that bolt head sinks to circular groove fully, reduced the width of secondary groove, for the Position Design of swing arm structure provides larger space, reduced processing, the assembling difficulty of whole DVD; The distortion at other positions that the structure that is communicated with circular groove by secondary groove has simultaneously caused when also having avoided only making circular groove has guaranteed the flatness of whole DVD base plate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Be illustrated in figure 1 as a kind of DVD base plate of SGCC material, comprise body 1, be provided with the identical circular groove of the degree of depth and secondary groove 2 at body 1, be communicated with by secondary groove 2 between the described circular groove; The diameter of described circular groove is greater than the width of secondary groove 2; Center in the circular groove bottom is provided with bolt connecting hole 3; The diameter of described circular groove greater than with the external diameter of the adaptive bolt head of bolt connecting hole 3, the width of described secondary groove 2 less than with the external diameter of the adaptive bolt head of bolt connecting hole 3.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
