Description

CD player door closure headstock gear

The utility model relates to CD player, more specifically is meant a kind of CD player door closure headstock gear.

In recent years, portable CD player becomes people's new lover, and especially it has and can be convenient to the advantage that people carry, and people can listen to music whenever and wherever possible easily.

With general conventional optical disc player, its door closure headstock gear (as shown in Figure 8), include: a door closure 60, upper casing 61, the button 62 on tool inclined-plane, bottom, one closes and covers slide block 63, this closes an end that covers slide block 63 is can buckle in the button hole 64 of door closure 60, close the end in addition that covers slide block 63 and be provided with a spring 65, but closing the bottom of covering slide block 63 is provided with a supporting guide and closes the lower plate 66 of covering slide block 63, and the fixedly screw of lower plate 66 and upper casing 61 or fastener etc., but, said apparatus is because the part number reaches six, not only the required consumed time of assembling work is more, and expending of cost is also also higher.

For this reason, at the shortcoming that above-mentioned CD player door closure headstock gear exists, fundamental purpose of the present utility model provides a kind of CD player door closure headstock gear.With the part number and the simple and easy linkage editor of simplifying most, just can reach the purpose that reliability is high and reduce cost.

To achieve these goals, the utility model adopts following technical scheme: this CD player door closure headstock gear includes a upper casing that is arranged on the player casing, a door closure is pivoted on the upper casing, be provided with one between door closure and upper casing and can supply the opening spring of door closure unlatching by elastic force, the edge of door closure is formed with a button hole, one edge of upper casing is formed with the key hole of a upper and lower perforation, is formed with one group of relative bullport in the key hole; One button, its end face are to form a press section, and the button bottom is formed with a directing pin in the bullport place relatively; Hook portion before forming one group on the bottom surface of upper casing, its below is to be formed with slot part, is formed with a backstop on the upper casing; One inaccessible grab, the one side forms an axial region, and this axial region is to place in the slot part, and an inclined-plane hook portion adjacent with axial region fastens the button hole place of door closure, and the end in addition of inaccessible grab forms an elastic, and the end of this elastic fastens location, backstop place.

Above-mentioned CD player door closure headstock gear, wherein, the button bottom forms one group and can be disposed into relative elastic fastening hook by key hole.

Above-mentioned CD player door closure headstock gear, wherein, elastic is slightly to be " 2 " font.

Compare with traditional CD player door closure headstock gear, because the utility model mainly comprises door closure, button and inaccessible grab, the button bottom has one group of directing pin, each directing pin can upper and lower action in the bullport of upper casing, and the edge of door closure is formed with button hole, inaccessible grab one side forms can pack into the preceding hook portion place of upper casing of axial region, inaccessible grab has inclined-plane hook portion and elastic, elastic is positioned at the button below, its upper casing backstop place, tail end location, the inclined-plane hook portion fastens the button hole place of door closure, after application of force pressing keys down, door closure is opened.Therefore have following advantage at least: with the number of parts of simplifying most, just can reach and improve the reliability that door closure opens and closes, simultaneously, required consumed time is less when assembling work, helps reducing the purpose of assembly cost.

Below in conjunction with drawings and Examples, further specify concrete structure of the present utility model.
