The utility model discloses technical scheme's further improvement lies in: the length of the lower sliding plate is longer than that of the rotary adjusting plate.
The utility model discloses technical scheme's further improvement lies in: the lower slide plate is provided with a fastening screw which is arranged on a part of the lower slide plate, which extends out of the rotation adjusting plate.
The utility model discloses technical scheme's further improvement lies in: the sliding groove is a dovetail groove.
The utility model discloses technical scheme's further improvement lies in: the spout is the groove of falling T.
The utility model discloses technical scheme's further improvement lies in: the length of the fixed bottom plate is 30-50 cm.
The utility model has the advantages that:
the utility model discloses a setting has the PMKD of spout, makes the regulating plate can slide along the spout, adjusts the position of fixing the projecting apparatus on the regulating plate through the regulating plate.
The utility model discloses it is articulated to use the damping pivot between the lower slide of regulating plate and the rotation regulating plate, can reach the problem of adjustment projecting apparatus angle through the angle between adjustment lower slide and the rotation regulating plate.

Detailed Description
The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
The utility model provides a projector that mark usefulness through setting up PMKD and regulating plate, reaches the problem of convenient adjustment projecting apparatus position and angle, makes the projecting apparatus can project suitable position. The following are specific examples:
the utility model relates to a projector that tender was used, including projector 1, PMKD 3 and regulating plate, as shown in fig. 1, fig. 2. The projector 1 is fixed to the adjustment plate. The fixed bottom plate 3 is fixed on a table top.
The fixed bottom plate 3 is detachably fixed on a table top, and the fixed bottom plate 3 is provided with a sliding groove 2 as shown in fig. 1. The adjusting plate can slide along the sliding groove 2 on the fixed bottom plate 3. The adjusting plate comprises a lower sliding plate 4 and a rotary adjusting plate 5. The rotary adjusting plate 5 is hinged with the lower sliding plate 4 through a damping rotating shaft. Because the damping rotating shaft is used for hinging, the angle of the projector 1 can be conveniently adjusted, and meanwhile, after the adjustment is finished, due to the damping characteristic of the damping rotating shaft, no other device for fixing the angle is needed under the action of external force, and the angle cannot deflect. The lower end surface of the lower sliding plate 4 is provided with a sliding limiting block 6, and the sliding limiting block 6 is embedded in the sliding chute 2 and is consistent with the sliding chute 2 in shape, so that the sliding limiting block 6 can slide along the sliding chute 2. The projector 1 is fixed to the upper end face of the rotating adjusting plate 5, the handle 7 is arranged on the side face of the lower sliding plate 4, and the adjusting plate is driven to slide along the sliding groove by holding the handle 7 tightly. The handle 7 is arranged on the side surface of the rotation adjusting plate 5, so that the angle of the projector 1 can be adjusted conveniently. The bottom surface of the lower sliding plate is provided with a plurality of idler wheels, the height distance between the lower sliding plate and the fixed bottom plate can be raised by the idler wheels, the sliding is smooth, and meanwhile, a space is provided for the installation and the movement of the damping rotating shaft.
Preferably, the length of the lower slide plate 4 is longer than that of the rotation adjusting plate 5, as shown in fig. 2. The lower sliding plate 4 is provided with a fastening screw 8, and correspondingly, the fixing bottom plate is provided with a plurality of strip-shaped holes. A fastening screw 8 is provided at a portion of the lower slide plate 4 that extends beyond the rotation adjustment plate 5. After the distance and height of the projector 1 are adjusted, they are fixed by fastening screws 8.
Preferably, the length of the fixed bottom plate 3 is 30-50 cm. The sliding groove 2 can be a dovetail groove or a T-shaped groove, and the sliding limiting block 6 can be smoothly clamped and fixed in the sliding groove 2.
The utility model discloses a setting has the PMKD of spout, makes the regulating plate can slide along the spout, adjusts the position of fixing the projecting apparatus on the regulating plate through the regulating plate.
The utility model discloses it is articulated to use the damping pivot between the lower slide of regulating plate and the rotation regulating plate, can reach the problem of adjustment projecting apparatus angle through the angle between adjustment lower slide and the rotation regulating plate.
It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
