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 reaching technique effect can fully understand and implement according to this.It should be noted that, only otherwise form conflict, each embodiment in the present invention and each feature in each embodiment can be combined with each other, and the technical scheme formed 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 be fixed together with box at the bottom of projector 9, this fixed frame is provided with rectangular recess, the first mounting blocks 2 and the second mounting blocks 6 containing left half-thread and right half-thread hole is provided with in described rectangular recess, and be provided with a threaded post 7 in the threaded hole of described left half-thread hole and the formation of right half-thread hole, stretch out downwards the first perforate that the position that box is corresponding at the bottom of projector is provided with, wherein, it is inner that described first mounting blocks and the second mounting blocks are located at described rectangular recess slidably, and be connected with the both sides of fixed frame with right spring 5 respectively by the left spring 3 fixed separately, wherein, fixed cap 1 on one is also installed on the top of fixed frame, and upper fixed cap is provided with the second perforate, described threaded post protrudes upward through described 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, threaded post can not be compressed into inside projector because of the weight of self after projector's angular setting is complete, when an external force is applied, can be compressed into.
When threaded post moves downward, stress surface when lower screw thread 202 is pull-outs, the angle of screw thread and horizontal direction is comparatively large, when pulling down threaded post, just can extract out by very little power, more convenient during projector's hue angle.
Because pull out different from threaded hole stress surface angle with threaded post during propelling, so just can realize just can pulling out threaded post gently, under the effect not having pressure, threaded post can not be pressed into because of projector's self gravitation.
Preferably, together with fixed lid fixes with fixed frame.
As long as threaded post can be adjusted to Position Approximate with have gentle hands is light once drawing when putting threaded post by this patent, then finely tune as classic method.More install additional simple when receiving threaded post, as long as with defeating projector, threaded post can slip into initial position automatically, structure is easy to realize, is adapted to the use of various projector.
More particularly, when pulling down threaded post, because during pull-out, the angle changing rate of stress surface is large, very little power is only needed just can left spring 5 and right spring 3 to compress, first mounting blocks 6 is moved to the left, second mounting blocks 2 moves right, when threaded post can rotary threaded column be finely tuned to during Position Approximate.
When to when pressing down projector, during propelling, the angle changing rate of stress surface is little, Gu need larger power to make left spring 5 and right spring 3 compress, 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 problem fast and accurately when projector regulates projection angle, and user uses also can be fast very convenient, and folding and unfolding is all very quick, compared with traditional control method, operates quicker, and be easy to just can realize.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
