Abstract
The utility model provides a 360 DEG rotary disk with a simple travel switch, which comprises a machine frame, a motor, a rotary shaft, a rotary disk, a positive rotation travel switch and a negative rotation travel switch. The utility model is characterized in that one swing rod is pivoted on the machine frame via a pivot shaft, a fixing shaft is arranged on the machine frame of the connecting line between the pivot shaft and a pivot shaft core, one return spring is arranged between the fixing shaft and a swing rod body, and a short pin which can dial the swing of the swing rod is arranged on the rotary disk. The positive rotation travel switch and the negative rotation travel switch are arranged at both sides of the swing range of the swinging end of the swing rod. The rotary disk can realize 360 DEG or more than 360 DEG angular rotation, and the utility model has the advantages of no generation of dead angles, no overlapping signal, simple structure, and low manufacturing cost. The utility model is suitable for the use of a billboard, a projecting lamp, and a camera shot wheel.
Description
The utility model relates to rotating disk mechanism, particularly a kind of 360 ° of rotating disks with simple and easy travel switch, the camera gun use that is fit to billboard, shot-light and does 360 ° of rotations.
Rotating disk is a kind of mechanical hook-up that can 360 ° of rotating disks of positive and negative work.In prior art, the method for control dial rotation angle has two kinds: the first is controlled with travel switch, and the recognizate that utilizes the contact of travel switch to touch recognizing site on the rotating disk carries out.The advantage of this method is a low cost, but not enough be that precision is low, rotating disk can not be done full 360 ° of rotations, and can not distinguish 360 ° and 0 ° of two signal; It two is to adopt digital disk control, reads the bar yardage by counter on digital disk and determines the disk position signal, and its advantage is the precision height, the no signal overlap problem, but shortcoming is used device price height, only requires simple rotating actuation mechanism for some, is difficult to accept.
The purpose of this utility model is to provide a kind of 360 ° of positive and negative rotations of doing, and 360 ° of rotating disks of the simple and easy travel switch that signal can be not overlapping newly design.
Task of the present utility model realizes by this way: this rotating disk include frame, motor, rotating shaft, rotating disk and just changeing, travel switch reverses, it is characterized in that on frame, articulating a fork by a drive-connecting shaft, on the frame of drive-connecting shaft and rotating shaft core line, be provided with a dead axle, between the dead axle and the fork body of rod, be provided with a back-moving spring, the short pin that can stir the fork swing is set on rotating disk.Just change one's profession Cheng Kaiguan and counter-rotating travel switch are set in the both sides of fork swinging end hunting range.
The utility model is work like this: the same with prior art, rotating disk is engaged with by the machine shaft shaft end gear and rotates.Short pin contacts fork on rotating disk makes it to oppress when just changing one's profession Cheng Kaiguan, and the motor-driven rotating disk is made forward rotation.When short pin leaves fork, under the effect of back-moving spring, the fork return.When the short pin on the rotating disk turns to when touching the fork another side and making it compressing counter-rotating travel switch, motor just drives rotating disk and makes backward rotation.In when assembling,, just can make the forward or reverse angle of rotating disk reach 360 ° or greater than 360 ° as long as adjust the angle of just changing one's profession between Cheng Kaiguan and the counter-rotating travel switch.This shows that compared with the prior art the utility model has following advantage:
1, rotating disk can be made 360 ° or big 360 ° rotational angle, does not produce the dead angle.
2, can distinguish two signals of 0 ° and 360 °, no signal is overlapping.
3, simple in structure, low cost.
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Fig. 1 is the utility model one embodiment concrete structure vertical view.
Fig. 2 is along the cut-open view of A-A line among Fig. 1.
Fig. 3 is the vertical view of another embodiment concrete structure of the utility model.
As shown in figures 1 and 3, the structure of frame 1, rotating disk 2, rotating shaft 3, motor 4 and just changing one's profession Cheng Kaiguan 5 and counter-rotating travel switch 6 is identical with technology is arranged basically.Difference is to establish a pivot 7 on frame 1, and fork 8 is articulated on the drive-connecting shaft 7.Dead axle 9 is arranged on the connecting line in drive-connecting shaft 7 and rotating shaft 3 axle center, between dead axle 9 and fork 8 back-moving spring 10 is set, and the short pin 11 that can stir fork 8 is set on rotating disk 2.Just change one's profession Cheng Kaiguan 5 and counter-rotating travel switch 6 are set in the both sides of fork 8 hunting ranges.The Cheng Kaiguan 5 that just changing one's profession should contact with the fork 8 of swing with counter-rotating travel switch 6, and the angle of its position should be decided according to rotating disk 2 required rotational angles.
Embodiment 1: as depicted in figs. 1 and 2, fork 8 is inclined to one side strip, is articulated on the drive-connecting shaft 7 with its middle part, and back-moving spring 10 is connected with fork 8 terminations with dead axle 9, and just changing one's profession Cheng Kaiguan 5 and counter-rotating travel switch 6 are arranged at the both sides of fork 8 other end hunting ranges.
