Abstract
The utility model discloses a kind of removable projector, comprise projector body, bearing, shaft type linear stepping motor and electric rotating machine, described shaft type linear stepping motor comprises screw rod and stepper motor, described stepper motor is arranged on described screw rod, described bearing is provided with cavity, one end of described screw rod is arranged in described cavity, the internal thread coordinated with described screw rod is provided with in described cavity, the other end of described screw rod is connected with described electric rotating machine, and the output shaft of described electric rotating machine is connected with described projector body.The utility model drives adjustment bolt rotary by stepper motor, relative displacement is there is in the cavity of bearing, realize highly regulating, electric rotating machine also can realize Plane Rotation simultaneously, autonomous adjustment projecting direction, structure is simple, easy to operate, realize synchronous adjustment projector, the situation that there will not be projecting plane to tilt occurs.
Description
Technical field
The utility model relates to a kind of projector, refers more particularly to a kind of removable projector.
Background technology
Projector be a kind of can by image or VIDEO PROJECTION to the equipment on curtain, same to computing machine, VCD, DVD, BD, game machine, DV etc. can be connected and play corresponding vision signal by different interfaces.Projector is widely used in family, office, school and public place of entertainment, and the front height of usual projector is realizing best projection quality close to presenting 20 with the plane of screen to during 30-degree angle place as far as possible.If the angle tilted is excessive or too small, the word of appearance and pattern are often comparatively fuzzy, and the projection of projector is bad, even occur that the situation that projecting plane tilts occurs.
Utility model content
It is simple that the purpose of this utility model is just to provide a kind of structure to solve the problem, the removable projector of convenient adjustment.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises projector body, bearing, shaft type linear stepping motor and electric rotating machine, described shaft type linear stepping motor comprises screw rod and stepper motor, described stepper motor is arranged on described screw rod, described bearing is provided with cavity, one end of described screw rod is arranged in described cavity, be provided with the internal thread coordinated with described screw rod in described cavity, the other end of described screw rod is connected with described electric rotating machine, and the output shaft of described electric rotating machine is connected with described projector body.
Further, described bearing settlement on the ceiling.
The beneficial effects of the utility model are:
The utility model drives adjustment bolt rotary by stepper motor, relative displacement is there is in the cavity of bearing, realize highly regulating, electric rotating machine also can realize Plane Rotation simultaneously, autonomous adjustment projecting direction, structure is simple, easy to operate, realize synchronous adjustment projector, the situation that there will not be projecting plane to tilt occurs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-stepper motor, 2-screw rod, 3-electric rotating machine, 4-projector body, 5-bearing, 6-cavity.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises projector body 4, bearing 5, shaft type linear stepping motor and electric rotating machine 3, described shaft type linear stepping motor comprises screw rod 2 and stepper motor 1, described stepper motor 1 is arranged on described screw rod 2, described bearing 5 is provided with cavity 6, one end of described screw rod 2 is arranged in described cavity 6, the internal thread coordinated with described screw rod 2 is provided with in described cavity 6, the other end of described screw rod is connected with described electric rotating machine 3, the output shaft of described electric rotating machine 3 is connected with described projector body 4, described bearing 5 is arranged on the ceiling.
Operating personnel are after setting fixing projection angle, adjustment screw rod 2 is driven to rotate by stepper motor 1, relative displacement is there is in the cavity 6 of bearing 5, realize highly regulating, electric rotating machine 3 also can realize Plane Rotation simultaneously, independently adjusts projecting direction, structure is simple, easy to operate, realize synchronous adjustment projector, the situation that there will not be projecting plane to tilt occurs.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
