The present invention is achieved through the following technical solutions its purpose:
A kind of focusing compensation device of projector lamp, be respectively equipped with two fixedly rubber roll and two swelling rubber rolls in the overhead projector and arranged on left and right sides, described swelling rubber roll is installed on the rotary components, this rotary components comprises the rotation support plate, rotates support plate and connecting rod down, the upper/lower terminal of described swelling rubber roll is connected to the rotation support plate and rotates support plate down by bearing, connecting rod will be gone up the rotation support plate and rotate support plate down and fix, and will be fixed in by bearing pin in the respective aperture of projection magic lamp base plate.
The outside of described swelling rubber roll is provided with first position block and second position block, and wherein first position block is installed on the projection magic lamp base plate, and second position block is installed in down on the rotation support plate; First position block is provided with screwed hole, and second position block is provided with the hand buttonhole, and a hand button that is provided with screw rod passes in the screwed hole that the hand buttonhole is tightened in first position block, and the screw portion of hand button is equipped with a spring.
The upper and lower end of described swelling rubber roll is connected with the rubber roll plug respectively, bearing be fixed in the rotation support plate and down the rotation support plate with the corresponding position of swelling rubber roll upper and lower end, the swelling rubber roll is by pack into bearing and rotating in bearing of rubber roll plug.
Innovative point of the present invention is on the base plate of projection magic lamp rotary components to be housed, and rotary components can rotate by bearing pin; Two swelling rubber rolls embed goes up the rotation support plate and the Inter of rotation support plate down and since the upper and lower side of swelling rubber roll with rotate the support plate bearing up and down and be connected, so two swelling rubber rolls can rotate; The first location link stopper and the second location link stopper are installed on the projection magic lamp base plate respectively and rotate on the support plate down, when the unclear needs of projection magic lamp irradiation pattern are reconciled, can regulate distance between two position blocks by rotating the two hand buttons of location between the link stoppers, thereby the driven rotary assembly rotates, change lantern slide and light-emitting window angle of inclination, reach the purpose of adjusting focal length, making clear picture.
The invention has the beneficial effects as follows:
1, this device is a kind of focusing compensation device of projector lamp, can finely tune the lantern slide angle of inclination at the scene, at any time according to the illumination pattern needs various angles that change irregularly, make all vernier focusings on the imaging surface that tilts of each point on the lantern slide, guarantee that the shadow surface each point is all clear, accurate, make its clear patterns that irradiates, improved performing effect.
2, easy to operate, improved staff's operating efficiency.
3, can satisfy the needs of large-scale performance projection magic lamp irradiation.
