Abstract
The utility model discloses a connecting structure of a projecting apparatus. The projecting apparatus is fixed on a base or a table top through a connecting bar, the connecting bar is a serpentine bar, on which a plurality of grooves and flanges are formed, and the grooves and the flanges can be twisted at will by the serpentine bar, when a user uses the projecting apparatus, the serpentine bar can be turned, so that the projecting apparatus can be turned at the needed position, and the light outlet surface of the projecting apparatus is caused to be parallel to the table top, thus the projecting ray can keep vertical to the table top, thereby ensuring that the projected image is clear and does not distort.
Description
Technical field
The utility model relates to the projection lamp that a kind of children learning machine is used, and refers to a kind of syndeton of projection arrangement especially.
Background technology
At present, the learning machine that uses to children has a variety of, a kind of learning machine of projection that is is wherein arranged, its structural principle is: fixedly mount or place a projection arrangement on a stand, film be can plug on this projection arrangement, various literal or pattern (comprising line image or multicolour pattern or the like) then are printed on the film.In use, open projection arrangement, light sees through film, and literal on the film or pattern will shine upon on the table, only needs to take pen to retouch according to the image that mirrors this moment and draws, and can reach the purpose that exercise is write or drawn a picture.
In the prior art, above-mentioned projection arrangement is by a connecting rod and base or direct-connected with desk, the syndeton be similar to electric fan then is set between projection arrangement and the connecting rod, make this projection arrangement can before and after or left-right rotation, to reach the purpose of regulating image position.Yet this rotational angle of projection arrangement is very limited, can't take each corner of desktop into account.And because this adjusting is to realize by the angle that changes projection arrangement, in case and angle changes, its throw light can not be perpendicular to desktop, will make deformation of image that projection goes out or smudgy clear like this.
The utility model content
At above-mentioned deficiency, the purpose of this utility model is to provide a kind of syndeton of projection arrangement, and it can make the projection arrangement wide-angle regulate, thereby it is vertical with desktop to make projection ray remain.
For achieving the above object, technical solution of the present utility model is:
A kind of syndeton of projection arrangement, this projection arrangement is fixed on base or the desktop by a connecting rod, and described connecting rod is snakelike bar, is formed with some grooves and flange on this snakelike bar.
After adopting such scheme, because the utility model is fixed in projection arrangement on base or the desktop by a snakelike bar, and some grooves that form on this snakelike bar and flange can make it reverse arbitrarily, when the user uses projection arrangement, can break this snakelike bar off with the fingers and thumb, make it be torqued into the position that needs, and make the exiting surface and the desktop keeping parallelism of projection arrangement, can make projection ray and desktop keep vertical like this, thereby make the image definition that projects indeformable.
Description of drawings
Fig. 1 is the structural representation that projection arrangement described in the utility model is positioned over desktop;
Fig. 2 is that the adjusting of connecting rod described in the utility model changes synoptic diagram.
Embodiment
As shown in Figure 1, what the utility model was related is a kind of projection arrangement, this projection arrangement is applied on the children learning machine, this children learning machine comprises a desk 1, on this desk 1, fix or be placed with a projection arrangement 2, this projection arrangement 2 is connected with a base 4 by a connecting rod 3, and perhaps this connecting rod 3 is directly fixed on the desktop of desk 1.Key of the present utility model is:
Described connecting rod 3 is snakelike bar, owing to be formed with some grooves 31 and flange 32 on the snakelike bar, can make snakelike bar reverse (as shown in Figure 2) arbitrarily like this.When the user uses projection arrangement, can break this snakelike bar off with the fingers and thumb, make it be torqued into the position that needs, and make the exiting surface and the desktop keeping parallelism of projection arrangement 2, can make projection ray and desktop keep vertical like this, thereby make the image definition that projects indeformable.
Claims (1)
1, a kind of syndeton of projection arrangement, this projection arrangement is fixed on base or the desktop by a connecting rod, it is characterized in that: described connecting rod is snakelike bar, is formed with some grooves and flange on this snakelike bar.
