Technical field
The utility model relates to multimedia projector, particularly relates to a kind of damper mechanism of multimedia projector.
Background technique
In society, multimedia technology application is extensive, and multimedia projector is a kind of more accurate equipment, can not stand larger vibrations, if make projector use in movement, as vehicle-mounted projector, just can be easy to damage.
Model utility content
The purpose of this utility model is just the damper mechanism providing a kind of multimedia projector in order to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of damper mechanism of multimedia projector, comprise cabinet, described projector is arranged in described cabinet, the top of described projector is provided with the first axle bed, described first axle bed is provided with transverse axis, the afterbody of described projector is provided with the second axle bed, described second axle bed is provided with vertical pivot, described transverse axis and described vertical pivot are all fixed in described cabinet, the two ends of described transverse axis are all set with horizontal torsion spring, one end of described horizontal torsion spring is connected with described first axle bed, the other end is fixed on described transverse axis, the two ends of described vertical pivot are all set with longitudinal torsion spring, one end of described longitudinal torsion spring is connected with described second axle bed, the other end is fixed on described vertical pivot.
By horizontal torsion spring, projector and transverse axis are carried out elasticity to be connected, by longitudinal torsion spring, projector and vertical pivot are carried out elasticity to be connected, and transverse axis and vertical pivot are all be fixed in cabinet, what ensure that projector can have at vertical direction and substantially horizontal the shock-absorbing capacity having inertial force, avoids projector and causes internal damage because shaking suddenly.
Particularly, the two ends of described transverse axis and the two ends of described vertical pivot are provided with draw-in groove, described cabinet is provided with transverse axis hole and vertical pivot hole, and be all provided with position-limited shaft in described transverse axis hole and described vertical pivot hole, described transverse axis and described vertical pivot are all installed on described position-limited shaft by described draw-in groove.
As preferably, the wire diameter of described horizontal torsion spring and described longitudinal torsion spring is 8 ~ 14mm.
As preferably, the diameter of described position-limited shaft is 8mm.
The beneficial effects of the utility model are:
Projector and transverse axis are carried out elasticity by horizontal torsion spring and are connected by the utility model, by longitudinal torsion spring, projector and vertical pivot are carried out elasticity to be connected, and transverse axis and vertical pivot are all be fixed in cabinet, ensure that the shock-absorbing capacity can at vertical direction and substantially horizontal with inertial force of projector, avoid projector and cause internal damage because shaking suddenly, ensure that projector can use in high-speed mobile, can be used as a kind of vehicle-mounted projecting device, extend its working life.
Accompanying drawing explanation
Fig. 1 be the damper mechanism of a kind of multimedia projector described in the utility model face structural representation;
Fig. 2 is the structural representation after the damper mechanism removing cabinet of a kind of multimedia projector described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model comprises cabinet 1, projector 4 is arranged in cabinet 1, the top of projector 4 is provided with the first axle bed 3, first axle bed 3 is provided with transverse axis 2, the afterbody of projector 4 is provided with the second axle bed 10, second axle bed 10 is provided with vertical pivot 8, transverse axis 2 and vertical pivot 8 are all fixed in cabinet 1, the two ends of transverse axis 2 and the two ends of vertical pivot 8 are provided with draw-in groove 9, cabinet 1 is provided with transverse axis hole and vertical pivot hole, in transverse axis hole and vertical pivot hole, position-limited shaft 7 is all installed, transverse axis 2 and vertical pivot 8 are all installed on position-limited shaft 7 by draw-in groove 9, the two ends of transverse axis 2 are all set with horizontal torsion spring 6, one end of horizontal torsion spring 6 is connected with the first axle bed 3, the other end is fixed on transverse axis 2, the two ends of vertical pivot 8 are all set with longitudinal torsion spring 5, one end of longitudinal torsion spring 5 is connected with the second axle bed 10, the other end is fixed on vertical pivot 8.
In the present embodiment, the wire diameter of horizontal torsion spring 6 and longitudinal torsion spring 5 is 8 ~ 14mm, the diameter of position-limited shaft is 8mm, such projector just can withstand sharp pounding and not damage, for the ease of, it should be noted that laterally and vertically by a movable position-limited shaft 7 and a fixing position-limited shaft 7, when transverse axis 2 and vertical pivot 8 snap fitted to after on fixing position-limited shaft 7, again the position-limited shaft 7 of activity is inserted the other end draw-in groove 9 place of transverse axis 2 in cabinet 1 and vertical pivot 8, in the drawings by this representation not out.
Projector 4 is carried out elasticity with transverse axis 2 by horizontal torsion spring 6 and is connected by the utility model, by longitudinal torsion spring 5, projector 4 is carried out elasticity with vertical pivot 8 to be connected, and transverse axis 2 and vertical pivot 8 are all be fixed in cabinet 1, ensure that the shock-absorbing capacity can at vertical direction and substantially horizontal with inertial force of projector 4, avoid projector 1 and cause internal damage because shaking suddenly.
