Abstract
The utility model relates to a movement component structure of a video disc player, in particular to a pressure plate elevating mechanism of a suction-type movement. The mechanism comprises a lifting frame of which the middle part is hinged on a fixed framework via a rotating shaft; a pressure plate capable of swinging vertically along the lifting frame is arranged at the front part of the lifting frame; a spring is connected between the rear part of the lifting frame and the fixed framework, and the direction of the spring force presses the pressure plate at the front part of the lifting frame downward; a gear rack capable of moving forwards and backwards is arranged below one side of the lifting frame, and a gear meshed with the gear rack is mounted on the fixed framework; and a dummy club is arranged on the gear rack for jacking the front part of the lifting frame upwards when the gear rack moves forward. The utility model has simple structure, convenient manufacture and installation as well as low cost, and the lifting frame under the spring force is lifted or lowered through moving the dummy club on the gear rack so as to realize the elevation of the pressure plate; moreover, the transmission link is simplified, and the action reliability is enhanced.
Description
Technical field
The utility model relates to the core part structure of video disc player, specifically is a kind of platen elevating mechanism of inhalation type machine core.
Background technology
Inhalation type machine core platen elevating mechanism is when the suction-type player loads video disc, is used to dodge the device of video disc, ballast dish.The elevating mechanism of the platen of existing inhalation type machine core is to form by the stamping parts iron plate of multilayer, and the operating principle of utilization lever carries out transmission, this kind mechanism structure complexity, and manufacturing and installation process are loaded down with trivial details, and reliable in action is lower, and cost is also higher.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, make easy for installation, reliable in action, inhalation type machine core platen elevating mechanism that cost is low.
Inhalation type machine core platen elevating mechanism of the present utility model includes a crane, and the middle part of crane is hinged on the fixed frame by rotating shaft; The crane front portion is provided with can be with the platen of the upper and lower swing of crane; Be connected with spring between crane rear portion and the fixed frame, the direction of spring force makes the platen of crane front portion to pressing down; Crane one side-lower is provided with a tooth bar that can move forward and backward, and one and tooth bar meshed gears are installed on the fixed frame; Tooth bar is provided with one section boss, is provided with the transition inclined-plane between the top of boss and the root, the boss jack-up that the front portion of crane can be made progress when tooth bar moves forward.
The utility model is simple in structure, manufacturing and easy for installation, cost is low, it is by the boss jack-up on the mobile rack or put down crane under the spring action, to realize the platen lifting process, transmission link is few, the reliable in action height.
Description of drawings
Fig. 1 is the utility model structure front schematic view;
Fig. 2 is the utility model structure reverse side synoptic diagram.
Embodiment
As shown in the figure, comprise the crane 1 that in the fixed frame of movement, to do swing by rotating shaft 2 in the mechanism of the present utility model, crane is swung by spring 3 and tooth bar 4 common drivings, boss 5 on the tooth bar contacts with the crane front side portion, and tooth bar 4 is driven by the gear on the fixed frame 6 and does the straight line back and forth movement.
In the movement course of work, when gear 6 forward rotation driving tooth bar 4 was done rectilinear motion, the boss 5 on the tooth bar just left crane 1, makes that under the effect of spring 3 crane is that the centre of gyration is done swing with rotating shaft 2, platen 7 on the crane is dropped on the video disc, play the effect of pressing dish; When gear 6 backward rotation drove tooth bar 4 and do rectilinear motion, boss 5 moved forward the jack-up crane that contact and make progress with crane 1 bottom, makes the platen 7 on the crane leave video disc.
Claims (2)
