Description
Technical field
The utility model relates to projection equipment field, relates in particular to that a kind of projector lens is fixed and changing device more.
Background technology
Projector need to could throw into screen by image by camera lens, for obtaining image clearly, conventionally the focal length, the enlargement factor that need adjustable lens, and the focal length of each camera lens and enlargement factor are all within the specific limits, when environment for use changes,, just there is the possibility of changing camera lens in the range of adjustment that exceeds focal length and enlargement factor.Environment for use mainly refers to projector lens to the distance of screen.In fact, the well matched standard lens of projector one, but space or the length or narrow used, standard lens is the difficult effect that obtains satisfaction also.If distance is short, will obtain large-sized image, just need short-focus lens, distance will obtain image clearly, just needs telephoto lens.
As mentioned above, projector likely configures several camera lenses, depending on environment for use, changes.Need to consider to change like this convenience of camera lens, and camera lens need to be installed firmly.
Current lens changing mode mainly contains two kinds:
1, camera lens and lens fixing base are together by a threaded connection, and camera lens need to be used screwdriver to unclamp, then changes.And the camera lens of projector is generally placed on machine intimate, while changing camera lens, first needs shell to take apart, then change.
2, the substitute mode of screwless, is generally to have individual button or dead man in machine exterior, unclamps camera lens, then take out camera lens by action button or dead man.
Be screwed the mode of camera lens, when carrying out lens changing, whole process is loaded down with trivial details, and in casing, has accurate optics, electron device, if frequent dismounting shell is easy to damage internal components.
The button of machine exterior or dead man, easily by people's maloperation, likely cause camera lens get loose and fall damage.
Utility model content
The purpose of this utility model is to provide that a kind of projector lens is fixed and changing device more, makes to change camera lens more convenient, and simple to operate, camera lens is installed firmly.
The technical solution of the utility model is that a kind of projector lens is fixed and changing device more, comprising: be fixed on fixation kit in housing, be buckled in front upper part of the cover handle cover assembly and lens assembly; Wherein, described fixation kit comprises: pedestal, be fixed on pedestal side set collar, be enclosed within the change on this set collar protruding circular ring external diameter, the handle that is fixed on the torsion spring in set collar and change and is fixed on change top simultaneously, torsion spring provides the coupling mechanism force of change on positive and negative both direction; There is briquetting change inner side; Described handle cover assembly comprises: lid, be enclosed within pulling out hand, be fixed on banking stop on the first reference column of lid inner side, be fixed on and pull out hand inner side and pull out the dead bolt on hand bolt and be fixed on the over cap on the second reference column of lid inner side on lid waist hole; On dead bolt, have extension spring, extension spring upper end hangs on dead bolt, and lower end hangs on the pulling-on piece of banking stop bottom; Described lens assembly comprises: the installing plate on camera lens, camera lens, be fixed on the lock dog of dust cap on protecgulum and dust cap inner side; There is wedge in installing plate outside.There is the first press strip the described set collar left and right sides, and there is the second press strip upper and lower both sides, and the first press strip and the second press strip are pressed in change, prevent change displacement diametrically.Pedestal is fixed on enclosure interior, and set collar is fixed on pedestal side, and change is enclosed within on the external diameter of described fixed lobe annulus.Described torsion spring one end is fixed on set collar, and the other end is fixed in change.Handle cover assembly is stuck in described protecgulum top by lid.Banking stop and dead bolt are fixed on the first reference column of lid inner side successively by pilot hole, pull out hand and from outside, pass successively the waist hole lid and banking stop, are threaded with dead bolt.When camera lens is installed, drawing hand upwards, pulls out the pull out hand bolt of hand by inner side and drives dead bolt to move upward, and dead bolt leaves lock dog, now exposes handle.Then camera lens is inserted in the camera aperture of protecgulum, swing handle, change is rotated thereupon, and the briquetting of change inner side compresses the wedge in installing plate outside fix.Unclamp and pull out hand, under the pulling force of extension spring, dead bolt bottom is stuck on the lock dog of dust cap inner side, has completed the installation of camera lens and has fixed; Dismounting is during camera lens, and drawing hand upwards pulls out the pull out hand bolt of hand by inner side and drives dead bolt to move upward, and dead bolt leaves lock dog.Then swing handle, handle drives change rotation, and the briquetting of change inner side leaves wedge, takes out camera lens, unclamps and pulls out hand, pulls out hand and resets, and has completed dismounting.When pulling out hand and moving up and down, pull out hand bolt and move up and down in waist hole, be not subject to the impact of lid and banking stop, the extension spring on dead bolt helps to pull out hand and moves downward, and is convenient to pull out hand and resets.In the technical program, only need swing handle, just can change camera lens, pull out hand handle is covered, prevent maloperation.Simple to operate, easy to use, briquetting is fixed camera lens, and camera lens is installed firmly.
Further, on described set collar, have notch, briquetting is arranged in notch.Briquetting can only carry out back rotation in notch, has limited the slewing area of change, makes accurately stationary wedge piece of briquetting, avoids sliding, and camera lens is installed firmly.
Further, described handle cover assembly also comprises by pilot hole and is fixed on the lubricated sheet on the first reference column.Lubricated sheet is fixed on the first reference column, between banking stop and dead bolt, reduces the resistance that dead bolt slides, and is convenient to dead bolt and fastens accurately or leave in time lock dog, easy to use.
Further, have hanging hole on pulling-on piece, extension spring lower end hangs in hanging hole.Be convenient to make extension spring to drive dead bolt to reset in time, indirect drive is pulled out hand and is resetted in time.In projector's use procedure, make dead bolt always with lock dog in buckling state, be convenient to fixedly pull out hand, prevent that handle from exposing the maloperation causing.
