Description
Technical field
The present invention relates to a kind of projector and projector's governor motion, belong to projector optical devices field.
Background technology
Along with social progress, people are more and more deep to the understanding of projector, also more and more higher to the requirement of projector, for example, his noise, sharpness, contrast, regulates projection orientation etc. automatically.
This patent by solve projector a projector upright desktop projection time projection angle problem, when current upright projection of projector, the existing certain methods of projection angle can go to control, such as directly adding a plastic whorl post, remove the projection angle of controlling projection machine by rotation, the advantage of this method is to carry out very accurate angular adjustment, but governing speed is very slow, all will be by regulating threaded post when each folding and unfolding, user can spend one long period and go folding and unfolding threaded post, loses time.
Summary of the invention
Technical matters to be solved by this invention is to provide one both can ensure angular adjustment precision, projector that again can quick adjustment projector projection angle.
It is as follows that the present invention solves the problems of the technologies described above taked technical scheme:
A kind of projector governor motion, comprise: the fixed frame being fixed together with box at the bottom of projector, this fixed frame is provided with connected in star, in described groove, be provided with the first mounting blocks and the second mounting blocks that contain left half-thread and right half-thread hole, and be provided with a threaded post in the threaded hole that described left half-thread hole and right half-thread hole form, the first perforate being provided with from position corresponding to box at the bottom of projector, stretch out downwards, wherein, described the first mounting blocks and the second mounting blocks are located at inside grooves slidably, and be connected with the both sides of fixed frame with right spring by the left spring fixing separately respectively, wherein, top at fixed frame is also provided with fixed cap on, and upper fixed cap is provided with the second perforate, described threaded post protrudes upward through described the second perforate.
Preferably, in the helicitic texture in described threaded post and left half-thread hole and right half-thread hole, the angle between upper screw thread and surface level is less than the angle between lower screw thread and surface level.
Preferably, together with fixed lid fixes with fixed frame.
A kind of projector, is provided with described projector's governor motion.
After the present invention has taked such scheme, only need user threaded post can be adjusted to general position once drawing gently, then finely tune by rotation, only need be with defeating projector while closing, just can disposable threaded post be reverted to initial position, and firmly economize, with respect to existing governor motion, it is relatively simple in structure, easy to adjust, has good effect.
Other features and advantages of the present invention will be set forth in the following description, and, partly from instructions, become apparent, or understand by implementing the present invention.Object of the present invention and other advantages can be realized and be obtained by specifically noted structure in write instructions, claims and accompanying drawing.

Embodiment
Describe embodiments of the present invention in detail below with reference to drawings and Examples, to the present invention, how application technology means solve technical matters whereby, and the implementation procedure of reaching technique effect can fully understand and implement according to this.It should be noted that, only otherwise form conflict, each feature in each embodiment and each embodiment in the present invention can mutually combine, and the technical scheme forming is all within protection scope of the present invention.
The invention provides a kind of novel projector and projector's governor motion, wherein, projector is provided with projector of the present invention governor motion.
As Fig. 1, 2, 3, shown in 4, described projector governor motion, comprise: the fixed frame 4 being fixed together with box at the bottom of projector 9, this fixed frame is provided with rectangular recess, in described rectangular recess, be provided with the first mounting blocks 2 and the second mounting blocks 6 that contain left half-thread and right half-thread hole, and be provided with a threaded post 7 in the threaded hole that described left half-thread hole and right half-thread hole form, the first perforate being provided with from position corresponding to box at the bottom of projector, stretch out downwards, wherein, described the first mounting blocks and the second mounting blocks are located at described rectangular recess inside slidably, and be connected with the both sides of fixed frame with right spring 5 by the left spring 3 fixing separately respectively, wherein, on the top of fixed frame, fixed cap 1 on is also installed, and upper fixed cap is provided with the second perforate, described threaded post protrudes upward through described the second perforate.
Preferably, in the helicitic texture in described threaded post and left half-thread hole and right half-thread hole, angle between upper screw thread 201 and surface level is less than the angle between lower screw thread 202 and surface level, this is explained, when threaded post moves upward, stress surface when upper screw thread 201 is propelling, the angle of screw thread and horizontal direction is less, after projector's angular setting is complete, can threaded post not compressed into projector the inside because of the weight of self, in the time applying external force, can be compressed into.
When threaded post moves downward, lower screw thread 202 is the stress surfaces in when pull-out, and the angle of screw thread and horizontal direction is larger, and while pulling down threaded post, the very little power of use just can be extracted out, more convenient when projector hue angle.
Because threaded post is different from threaded hole stress surface angle while pulling out with propelling, so just can realize and just can pull out gently threaded post, under the effect that there is no pressure, threaded post can not be pressed into because of projector's self gravitation.
Preferably, together with fixed lid fixes with fixed frame.
When putting threaded post, this patent as long as threaded post can be adjusted to Position Approximate with have gentle hands is light once drawing, then as classic method, finely tunes.While receiving threaded post, more install additional simply, as long as with defeating projector, threaded post can slip into initial position automatically, is easy to realize in structure, is adapted to the use of various projectors.
More particularly, in the time pulling down threaded post, during due to pull-out, the angle of stress surface is larger, only need very little power just can left spring 5 and right spring 3 compress, the first mounting blocks 6 is moved to the left, the second mounting blocks 2 moves right, when threaded post can rotary threaded column be finely tuned during to Position Approximate.
When pressing down projector, when propelling, the angle of stress surface is smaller, Gu need larger power that left spring 5 and right spring 3 are compressed, the first mounting blocks 6 is moved to the left, and the second mounting blocks 2 moves right, and makes threaded post get back to initial position.
This patent can solve projector and regulate when projection angle problem fast and accurately, user use also can be very convenient folding and unfolding is all very quick fast, compared with traditional control method, operate quicker, and be easy to just can realize.
Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
