[0017] The utility model embodiment provides equatorial mechanical limiting and mechanical zero position mechanism based on sensor cooperation.

[0018] Please refer to Figure 1 , Figure 2 and Figure 3, including the installation of the card seat 1, the top surface of the mounting card seat 1 is fixedly connected with the holder 2, the inside of the holder 2 is rotatably connected with the harmonic reducer output end 3, the harmonic reducer output end 3 can transmit the power after deceleration to the mechanical equipment, so that the rotating adjusting assembly 7 can drive the equatorial mount 4 to rotate in the harmonic reducer output end 3 according to the set parameters, thereby providing power for the subsequent automatic reset of the equatorial mount 4.

[0019] The outer surface of the equatorial mount 4 is fixedly connected with the declination adapter 10, which facilitates the use of personnel to install astronomical telescopes or cameras and other star observation equipment on the equatorial mount, so that the equatorial mount can play the role of assisting star observation. The holder 2, the harmonic reducer output end 3 and the rotating adjusting assembly 7 involved in the present application are all prior art, and will not be described in detail in the present application.

[0020] The end of the harmonic reducer output end 3 is rotatably connected with the equatorial mount 4, the inside of the harmonic reducer output end 3 is rotatably connected with the rotating adjusting assembly 7, the rotating adjusting assembly 7 is fixed in the inside of the equatorial mount 4, the rotating adjusting assembly 7 can adjust the rotation angle of the equatorial mount 4 relative to the harmonic reducer output end 3 according to the signal transmission of the zero position probe 8 and the limit position probe 9 under the drive of the harmonic reducer output end 3, so that the device can realize the functions of automatic limiting and resetting. The equatorial mount 4 is prior art, and the inside is provided with a motor, a synchronous wheel and other existing equipment, and detailed equipment introduction is not within the scope of the present application, so it will not be described in detail.

[0021] The inside of the harmonic reducer output end 3 is fixedly connected with the adapter assembly 5, the outside of the adapter assembly 5 is fixedly connected with the metal semicircular ring 6, the metal semicircular ring 6 is made of metal material, which can detect the reaction of the zero position probe 8 and the limit position probe 9, so that the zero position probe 8 and the limit position probe 9 can control the rotation angle of the equatorial mount 4 according to the position change of the metal semicircular ring 6, avoiding the rotation angle of the equatorial mount 4 being too large to collide with the tripod below, improving the use safety of the device.

[0022] The inside of the rotating adjusting assembly 7 is fixedly provided with the zero position probe 8 and the limit position probe 9, the zero position probe 8 and the limit position probe 9 are adapted to the metal semicircular ring 6, and the zero position probe 8 and the limit position probe 9 are distributed at a right angle on the disc. When the limit position probe 9 detects the metal semicircular ring 6, the limit position probe 9 transmits a signal to the rotating adjusting assembly 7, so that the rotating adjusting assembly 7 stops rotating.

[0023] When starting, the zero position probe 8 will detect the zero position according to the relative position of the metal semicircular ring. When the zero position probe 8 detects the corresponding position information, the equatorial mount will stop rotating, so that it is in the zero position.

[0024] The zero-position probe 8 and the limit-position probe 9 both belong to a kind of metal sensor, and are prior art, which will not be described in detail in the present application.

[0025] Working principle: when the observer uses the device to observe stars, if the equatorial telescope main body 4 rotates to the east / west 90-degree angle position on the harmonic reducer output end 3, the limit-position probe 9 contacts the metal semi-ring 6 on the adapter assembly 5, at this time, the limit-position probe 9 transmits a signal to the rotation adjusting assembly 7, and the rotation adjusting assembly 7 stops rotating after receiving the signal,

[0026] The zero-position function and the limit-position function can avoid the collision between the equipment installed on the equatorial telescope main body 4 and the supporting tripod at the bottom due to the excessively large rotating angle of the equatorial telescope main body 4.
