Abstract
The utility model discloses a lifting and falling mounting for a digital projector, comprising a movable bracket and a fixed under frame. The front end of the movable bracket is hinged with the front end of the fixed under frame. A mechanism which can make the movable bracket rotate winding the hinged end is arranged between the movable bracket and the fixed under frame. The mechanism which can make the movable bracket rotate winding the hinged end comprises a rotary screw rod. The rotary screw rod is fixed on the fixed under frame horizontally and lengthways. A sliding block is sheathed on the screw rod and generates the horizontal and lengthways displacement according to the rotation of the screw rod. Two supporting arms are provided. Both ends of each supporting arm are respectively hinged on the left side or the right side of the sliding block and the upper face of the movable bracket. The front end part of the movable bracket is also provided with a lens rack which can install a widening lens. The utility model adopting the structure can fixedly install digital projectors with various types, can guarantee adjusting the widening lens arranged in external synchronously and can make the optical axle center of the lens in projecting keep consistent with the projecting optical axle center. The lifting and falling mounting for the digital projector adjusts the pitching easily and freely.
Description
Technical field
The utility model relates to cinematographic equipment, is specifically related to a kind of digital projecting device crane.
Background technology
Existing digital projecting device is on the fastening casing that is installed in built-in data processing equipment a bit, and in case after being placed on the casing, the projection angle of pitch of numeral projecting device is regulated and then must be handled together by related casing, and therefore conventional angle of pitch control method is to realize by the angle of inclination that changes casing.Because digital projecting device and both weight of casing are bigger, therefore conventional control method is not only time-consuming but also require great effort when reality is implemented, and very unreliable, is difficult to guarantee the show quality of digital projecting device.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of digital projecting device crane is provided, and it can be easily carries out more reliable, the accurate adjusting to the projection angle of pitch of digital projecting device.
For achieving the above object, the technical solution of the utility model is as follows: digital projecting device crane, it has a Movable bracket and a fixed frame, Movable bracket front end and fixed frame front end are hinged, and are provided with one between Movable bracket and the fixed frame and can make Movable bracket around mechanism that hinged end rotates.
But the above-mentioned Movable bracket that makes comprises the screw rod of a turn around the mechanism that hinged end rotates, and level is vertically fixed on the fixed frame; One slide block is enclosed within on the screw rod and can the occurred level length travel according to the turn of screw rod; And two support arms, on the two ends of each support arm are hinged on below the left side of slide block or right flank and the Movable bracket respectively.
Above-mentioned slide block is made up of top shoe and sliding block, top shoe and sliding block place respectively fixed frame top and below, and with have two slotted eyes longitudinally on the corresponding fixed frame in slide position, be equipped with the screw that one or two end connects upper and lower slide block respectively in each slotted eye.
For the optical axis that makes digital projecting device remains consistent with the expansion camera lens optical axis, the leading section of above-mentioned Movable bracket also installs one in order to install to expand the lens bracket of camera lens, and the pitch regulation that makes digital projecting device and the pitch regulation of expanding camera lens are one integrally-regulated.
The utility model is owing to adopt said structure, can be with the fastening installation of digital projecting device of various models, pitch regulation is freely simple and easy, and can guarantee that external expansion camera lens can adjust synchronously, when making projection the camera lens optical axis center with show optical axis center and remain consistent.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of fixed frame described in the utility model;
Fig. 3 is that the A of Fig. 2 is to the sectional structure synoptic diagram;
Fig. 4 is the structural representation that the utility model is realized pitch regulation.
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model has a Movable bracket 1 and a fixed frame 2, and Movable bracket 1 front end and fixed frame 2 front ends are hinged.Movable bracket 1 leading section installing one is in order to install the lens bracket 11 of expanding camera lens, installing one drawer type cooling fan box 12 below it.But fixed frame 2 has the screw rod 3 of a turn, and its both ends horizontal is vertically fixed in above the fixed frame 2, and screw rod 3 one ends extend a handwheel 31.Be with a slide block 4 with thread connecting mode on the screw rod 3, slide block 4 is made up of with sliding block 42 top shoe 41 and is connected by two attachment screws 43.Top shoe 41 and sliding block 42 place respectively the top of fixed frame 2 and below, and the nail body portion of two attachment screws 43 place respectively be opened on the fixed frame 2 and with corresponding two the vertical slotted eyes 21 in slide block 4 positions.The and arranged on left and right sides of slide block 4 is a hinged support arm 5 respectively, and the other end of support arm 5 is hinged on below the travel(l)ing rest 1.Also have two braces 6, the two ends of each brace 6 are hinged on respectively on the left side or right edge of Movable bracket 1 and fixed frame 2.
As Fig. 1, shown in Figure 4, make slide block slotted eye generation longitudinally length travel by shaking the rotation of handwheel drive screw rod, and the promotion of the length travel of slide block by support arm makes Movable bracket rotate around hinged end, thereby realize being fastened on the pitch regulation of the digital projecting device on the Movable bracket, and since lens bracket and Movable bracket fuse, thereby also the realization pitching that is installed in the expansion camera lens in the lens bracket is adjusted synchronously.The effect of supporting and assisting Movable bracket to rotate is played in two braces at this moment.The cooling fan box adopts drawer type, makes easier maintenance of fan and replacing.
