Abstract
The utility model relates to a portable video data demonstrating device, relating to the technical field of data demonstrating devices. The utility model comprises and is composed of a demonstrating table plate, a rear projection plate, a camera, an additional light source lamp, supporting rods, etc. The demonstrating table plate is provided with a rotary supporting seat; the middles of the supporting rods and the rotary supporting seat, the middles of the supporting rods and the middles of supporting rods and the camera are connected by hinges; the connecting positions between the supporting rods are connected by the rotary supporting seat and the additional light source lamp. The portable video data demonstrating device with the structure of the utility model has the advantages of simple structure, low cost, convenient operation, convenient carrying, etc. and can realize omnibearing rotation and fixing.
Description
The utility model relates to data demonstration equipment technical field, particularly a kind of portable video data apparatus for demonstrating.
Traditional be used for teaching or other industry data apparatus for demonstrating mostly is projector.Though projector can be realized the purpose of demonstration, needing to be depicted as transparency by demonstration thing or photo information can demonstrate, and the technology of paint projection sheet complicated and draw after can't change, in presentation process, will be subjected to the influence of surrounding environment light simultaneously.The demonstration effect is also undesirable.Continuous development along with science and technology.The projector for real object of various models and multimedia document demonstration device are put on market in succession, though function is many, good demonstration effect, preferably resolve various data demonstration problems, but its complex structure, the manufacturing cost height is not easy to carry, and the running program complexity, thereby cause very big difficulty to popularization and application.
Goal of the invention of the present utility model is that a kind of portable video data apparatus for demonstrating simple in structure, easy to operate, portable will be provided.
Foregoing invention purpose of the present utility model realizes by following technical proposals:
Portable video data apparatus for demonstrating, comprise: several parts such as demonstration platen, rear-projection plate, video camera, additional source of light lamp, support bar, back projection light source, power control switch, ac power plug, video output terminal are formed, it is characterized in that on the described demonstration platen rotary support being set, between support bar and the rotary support, between support bar and the support bar, all be connected through the hinge between support bar and the video camera, connecting portion is connected with the additional source of light lamp by rotary support between the support bar.
On the described demonstration platen rotary support is set, between support bar and the rotary support, between support bar and the support bar, all be connected through the hinge between support bar and the video camera, connecting portion is connected with the additional source of light lamp by rotary support between the support bar, purpose is to form a collapsible support bar, two ends are connected with demonstration platen, video camera respectively, the centre is connected with the additional source of light lamp, rotatable 270 ° of rotary support, hinge connects rotatable 180 °, thereby can make pick-up lens carry out three-dimensional rotation, realize omnibearing rotation and fixing.Can regulate, rotate collapsible support bar according to the needs of camera angle and position, regulate picture size to reach, determine the local and whole purpose of displaying articles, video camera can carry out the adjustment of different azimuth and fix, so that alignment lens is demonstrated article, thereby realize comprehensive multi-angle picked-up picture, to being placed on the quilt demonstration thing on the demonstration table top, can reach the demonstration work of ideal effect equally.Be connected with the additional source of light lamp in the middle of the collapsible support bar, can open the additional source of light lamp switch, regulate additional source of light lamp angle, make additional source of light lamp light invest the demonstration platen, and can avoid reflective phenomenon influence demonstration effect according to on-the-spot light conditions needs.Simultaneously, after finishing using, support bar can be rotated to and demonstrate the parallel angle of bedplate surface, easy to carry and store.
The design of back projection light source and employing rear-projection plate is set in the demonstration platen, is convenient to transparency, lantern slide are demonstrated, thereby realizes multi-functional demonstration task.
The portable video data apparatus for demonstrating of the utility model structure, have simple in structure, with low cost, stable performance, easy to operate, advantage such as be easy to carry, can make camera lens carry out three-dimensional rotation, realize golden orientation rotation and fixing, be a kind of universal multi-functional data apparatus for demonstrating that is suitable for.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
