[0019] This embodiment provides a manual / automatic turntable locking device 100, including a rotary drive 110, a transmission assembly 120, a locking shaft 130, and a handle 140.

[0020] The rotary drive 110 is connected to the locking shaft 130 via the transmission assembly 120. The rotary drive 110 is a non-self-locking motor or servo motor. When not powered, the shaft of the rotary drive 110 has a certain holding force but can still be rotated. The transmission assembly 120 transmits and converts power, converting the rotation of the shaft of the rotary drive 110 into linear movement of the locking shaft 130, and vice versa. The locking shaft 130 is inserted into a socket on the photoelectric turntable to lock it. A handle 140 is provided at one end of the locking shaft 130, allowing for manual pulling to remove the locking mechanism from the photoelectric turntable and release its locked state.

[0021] The specific working principle of the turntable locking device 100 is as follows: When the photoelectric turntable needs to be locked, the rotating shaft of the rotary drive 110 rotates in the forward direction, driving the locking shaft 130 to move linearly through the transmission assembly 120. This causes the locking shaft 130 to insert into the insertion hole of the photoelectric turntable, locking the turntable and fixing its angle. Since the locking shaft 130 and the photoelectric turntable are connected by a plug-in joint, the rotational tendency of the turntable itself does not allow the locking shaft 130 to disengage from the insertion hole. Furthermore, because the rotating shaft of the rotary drive 110 has a certain holding force, the locking shaft 130 can be stably inserted into the insertion hole, improving the locking stability of the photoelectric turntable.

[0022] When the photoelectric turntable needs to be rotated, the operator manually grasps the handle 140 and pulls the locking shaft 130 to disengage the locking shaft 130 from the insertion hole of the photoelectric turntable, thus releasing the locking state of the photoelectric turntable. When pulling the locking shaft 130, the pulling force applied to the locking shaft 130 needs to overcome the holding force of the rotating shaft of the rotary drive component 110, so that the rotating shaft of the rotary drive component 110 rotates synchronously in the opposite direction.

[0023] In summary, this embodiment utilizes the cooperation of the rotary drive 110, transmission assembly 120, locking shaft 130, and handle 140. The clockwise rotation of the rotary drive 110 drives the locking shaft 130 linearly and inserts it into the socket of the photoelectric turntable, thus locking the turntable. Manually grasping the handle 140 and pulling the locking shaft 130 overcomes the holding force of the rotary drive 110, disengaging the locking shaft 130 from the socket of the photoelectric turntable and releasing the turntable from its locked state. This turntable locking device 100 simultaneously possesses both electric and manual locking functions, resulting in a simple structure and small footprint.

[0024] In one embodiment, the handle portion 140 is configured as a polygonal boss structure, which is located at the end of the locking shaft 130 and integrally formed with the locking shaft 130, providing both easy gripping and high structural strength. Optionally, the handle portion 140 may also be configured as a pull ring, pull rod, or other structure.

[0025] In one embodiment, the transmission assembly 120 includes a gear 121 mounted on the shaft of the rotary drive 110 and a rack 122 mounted on the locking shaft 130, with the gear 121 and rack 122 meshing together. When locking the photoelectric turntable, the rotary drive 110 drives the gear 121 to rotate forward, and the gear 121 drives the rack 122 and locking shaft 130 to move synchronously toward the photoelectric turntable until the locking shaft 130 is inserted into the insertion hole of the photoelectric turntable. When releasing the photoelectric turntable, the locking shaft 130 is pulled outward by the handle 140, and the locking shaft 130 drives the rack 122 to move synchronously. Relying on the meshing of the rack 122 and gear 121, the shaft of the rotary drive 110 rotates in the opposite direction.

[0026] In one embodiment, the rack 122 is mounted on the locking shaft 130 via a clearance adjustment assembly 150, which adjusts the meshing clearance between the rack 122 and the gear 121. Specifically, the clearance adjustment assembly 150 includes a bolt 151, the rack 122 has a slotted hole 152 through which the bolt 151 passes, and the locking shaft 130 has a threaded hole 153 adapted to the bolt 151. Preferably, two bolts 151, two slotted holes 152, and two threaded holes 153 are provided. The bolt 151 passes through the slotted hole 152 and connects to the threaded hole 153, pressing and fixing the rack 122 onto the locking shaft 130. Before the bolt 151 is tightened, the position of the rack 122 can be adjusted up and down through the slotted hole 152, thereby adjusting the meshing clearance between the rack 122 and the gear 121.

[0027] In one embodiment, the locking shaft 130 is provided with a mounting groove 131. The side of the mounting groove 131 that mates with the rack 122 is made into a plane, which increases the contact area between the rack 122 and the locking shaft 130 and improves the stability of the rack 122 installation. The mounting groove 131 is open on the side facing the gear 121, so that the rack 122 can mesh with the gear 121 above it.

[0028] In one embodiment, the turntable locking device 100 further includes a mounting housing 160, a rotary drive 110 is installed inside the mounting housing 160, and a locking shaft 130 passes through the mounting housing 160, with both ends of the locking shaft 130 located outside the mounting housing 160, so that one end of the locking shaft 130 can be inserted into the insertion hole of the photoelectric turntable, and also facilitates pulling out the handle 140 at the other end of the locking shaft 130. Specifically, the mounting housing 160 includes a housing body 161 and a front cover plate 162 and a rear tail plate 163 installed on the front and rear sides of the housing body 161. The housing body 161 has symmetrical through holes 164 for the locking shaft 130 to pass through, and the locking shaft 130 slides in the through holes 164.

[0029] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
