[0034] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a laser imaging device provided in an embodiment of the present application. This laser imaging device can be used in the field of surveillance, replacing human observation to obtain images from the laser eyepiece, thereby improving the accuracy of operations. The laser imaging device 10 includes an imaging mechanism 100, a connecting mechanism 200, and a focusing mechanism 300.

[0035] Among them, the connecting mechanism 200 is arranged on the focusing ring of the laser; the imaging mechanism 100 is arranged on the connecting mechanism 200, and is used to pass through the connecting mechanism 200 to contact the eyepiece of the laser to obtain the image in the eyepiece and send the image to an external device; the focusing mechanism 300 is mounted on the outer periphery of the focusing ring.

[0036] Illustratively, after the image is presented in the eyepiece of the laser, the focusing mechanism 300 can drive the focusing ring of the laser to rotate to make the image in the laser eyepiece clearer. The connecting mechanism 200 is used to fix the imaging mechanism 100. The imaging mechanism 100 observes and obtains the image in the laser eyepiece by contacting the eyepiece of the laser, and then sends the obtained image to an external device, such as a computer, for the staff to perform operations, so that the staff does not need to observe the image in the laser eyepiece with their eyes, avoiding the inconvenience of manual operation and the low accuracy caused by instability.

[0037] Exemplarily, the imaging mechanism 100 includes an imaging component board 110 and a fixed-focus lens 120; the imaging component board 110 is set on the connecting mechanism 200 for sending the image to an external device; the fixed-focus lens 120 is connected to the imaging component board 110 and is used to connect to the eyepiece of the laser through the connecting mechanism 200 to obtain the image in the eyepiece and send it to the imaging component board 110.

[0038] Exemplarily, the fixed-focus lens 120 is installed on the side where the imaging component board 110 is connected to the connecting mechanism 200. After the eyepiece of the laser presents the image, it is focused by the focusing mechanism 300 to display a clearer image. The fixed-focus lens 120 observes and obtains the image in the eyepiece and sends it to the imaging component board 110. The imaging component board 110 further transmits the received image to an external device for operation and processing by the staff, thereby realizing automatic observation and acquisition of the image in the laser eyepiece, effectively reducing the inconvenience and instability caused by manual operation.

[0039] In one embodiment, the imaging component board 110 may be electrically connected to an external device, or may send the captured image to the external device via wireless transmission, which is not limited in any way.

[0040] Exemplarily, the connecting mechanism 200 includes a connecting bracket 210 and at least two pillars 220; the connecting bracket 210 is arranged on the focusing ring of the laser for shading; at least two pillars 220 are arranged on the connecting bracket 210 and connected to the imaging mechanism 100 for fixing and positioning the imaging mechanism 100 so that the imaging mechanism 100 contacts the eyepiece of the laser.

[0041] Exemplarily, the imaging mechanism 100 is mounted on a connecting bracket 210 via at least two pillars 220, and then contacts the eyepiece of the laser through the connecting bracket 210 to observe and acquire the image. The connecting bracket 210 can effectively reduce the influence of the external light source on the imaging mechanism 100 and improve the quality of the acquired image.

[0042] Exemplarily, the connecting bracket 210 includes a first through hole, and the imaging mechanism 100 contacts the eyepiece of the laser through the first through hole.

[0043] The imaging mechanism 100 contacts the laser eyepiece through the first through hole, so that the contact position between the imaging mechanism 100 and the laser eyepiece is located inside the connecting bracket 210, thereby ensuring that the imaging mechanism 100 can avoid being affected by external light sources to a great extent when observing and acquiring the image in the laser eyepiece, thereby improving the clarity of the acquired image.

[0044] Preferably, the shape of the connecting bracket 210 can be cylindrical, or square cylindrical, or any other shape that can achieve its light shielding and corresponding functions.

[0045] In one embodiment, the diameter of the first through hole of the connecting bracket 210 is larger than the diameter of the laser eyepiece, and is fixed to the end face of the focusing ring and is coaxial with the laser eyepiece, and can rotate with the focusing ring.

[0046] In one embodiment, the diameter of the connecting bracket 210 can be the same as the diameter of the laser eyepiece, and it is connected and fixed to the edge of the laser eyepiece, and is coaxial with the laser eyepiece, and does not rotate with the focusing ring.

[0047] Exemplarily, the focusing mechanism 300 includes an adjusting gear 310 and an adjusting part 320; the adjusting gear 310 is mounted on the periphery of the focusing ring; the adjusting part 320 is arranged on the outer shell of the laser and connected to the adjusting gear 310 for performing a zeroing operation on the angle of the adjusting gear 310.

[0048] For example, the adjustment part 320 can set the angle of the adjustment gear 310 to zero, and then the adjustment gear 310 drives the focusing ring to rotate to focus the laser eyepiece, so that the rotation angle of the adjustment gear 310 can be more accurately grasped, and the laser eyepiece can be focused more accurately.

[0049] Exemplarily, the adjustment part 320 includes an optical coupler switch 321 and a paddle 322; the optical coupler switch 321 is set on the housing of the laser; the paddle 322 is set on the adjustment gear 310, and when the paddle 322 passes through the opening of the optical coupler switch 321 under the rotation of the adjustment gear 310, the angle of the adjustment gear 310 is set to zero.

[0050] Exemplarily, the paddle 322 is mounted on the end face of the gear surface of the adjustment gear 310, and the end face is exposed so that when the paddle 322 rotates with the adjustment gear 310, it can pass through the opening of the optocoupler switch 321 toward the side of the adjustment gear 310. When the paddle 322 passes through the opening of the optocoupler switch 321, the angle of the adjustment gear 310 will be set to zero, so that the rotation angle can be accurately grasped.

[0051] Exemplarily, the adjusting gear 310 includes at least one through hole; at least one screw passes through the at least one through hole, so that the adjusting gear 310 is fitted onto and fixed on the focusing ring.

[0052] Illustratively, there is at least one through hole on the gear surface of the adjustment gear 310 , so that the adjustment gear 310 can be fixed to the focusing ring of the laser through a screw to drive the focusing ring to rotate.

[0053] In one embodiment, the imaging device 10 for a laser further includes a driving mechanism 400 ; the driving mechanism 400 is disposed on the housing of the laser and connected to the focusing mechanism 300 , and is used to drive the focusing mechanism 300 to focus the laser.

[0054] For example, the driving mechanism 400 can drive the focusing mechanism 300 to drive the focusing ring of the laser to rotate, and then focus the laser eyepiece, thereby realizing automatic focusing of the laser eyepiece, which can avoid the problems of errors and troublesome operations caused by manual operation.

[0055] Exemplarily, the driving mechanism 400 includes a motor 410, a motor housing 420 and a driving gear 430; the motor housing 420 is arranged on the housing of the laser; the motor 410 is arranged inside the motor housing 420; the driving gear 430 is connected to the motor 410 and to the focusing mechanism 300.

[0056] Exemplarily, the motor 410 is disposed in the motor housing 420 and is installed on the housing of the laser through the motor housing 420. The motor 410 can drive the driving gear 430 to rotate. The driving gear 430 drives the focusing mechanism 300 to work by rotating, thereby driving the focusing ring of the laser to rotate, thereby focusing the laser eyepiece, thereby realizing automatic focusing of the laser eyepiece.

[0057] In one embodiment, the imaging device 10 for a laser further includes an anti-lock mechanism 500 ; the anti-lock mechanism 500 is disposed on the housing of the laser and is connected to the driving mechanism 400 .

[0058] For example, when the focusing mechanism 300 is stuck, in the absence of the anti-lock mechanism 500, since the driving mechanism 400 is connected to the focusing mechanism 300 and provides power to it, the driving mechanism 400 may be stuck, which may cause damage to the driving mechanism 400. After the anti-lock mechanism 500 is set, the driving mechanism 400 is not connected to the laser housing, but is installed on the laser housing through the anti-lock mechanism 500. When the focusing mechanism 300 is stuck, the driving mechanism 400 will rebound under the action of its power, so that the driving mechanism 400 is separated from the focusing mechanism 300, thereby ensuring that the driving mechanism 400 can continue to operate without being locked and damaged due to the jamming of the focusing mechanism 300, thereby improving the stability and safety of the operation.

[0059] In one embodiment, the anti-lock mechanism 500 may use a spring to ensure that the driving mechanism 400 can achieve a rebound effect when the focusing mechanism 300 is locked.

[0060] Specifically, when the staff needs to observe and obtain the image in the eyepiece of the laser in the monitoring device, the fixed-focus lens 120 of the imaging mechanism 100 can be controlled by an external device to observe and obtain the image in the laser eyepiece. After the fixed-focus lens 120 obtains the image, it sends the image to the imaging component board 110. Further, the imaging component board 110 sends the image to the external device. The staff can observe and process the received image through the external device to complete the corresponding task; if the obtained image is not clear, the staff can control the motor 410 of the driving mechanism 400 to work, and the motor 410 drives the driving gear 430 to rotate. Further, the driving gear 430 drives the adjusting gear 310 of the focusing mechanism 300 to rotate. The staff can control the adjusting gear 310 to rotate so that the adjusting part 320 The paddle 322 passes through the opening of the optical coupling switch 321 to set the angle of the adjustment gear 310 to zero, thereby improving the focusing accuracy. The adjustment gear 310 further drives the focusing ring of the laser to rotate, and then focuses the eyepiece of the laser mirror; when the adjustment gear 310 is locked, the driving mechanism 400 can act on the adjustment gear 310 through the driving gear 430 to generate a reaction force, causing the driving mechanism 400 to rebound, and then the anti-lock mechanism 500 is deformed, and when recovering, the driving gear 430 of the driving mechanism 400 contacts the adjustment gear 310 again, and then rebounds again, and so on and so forth, thereby ensuring that the motor 410 of the driving mechanism 400 can maintain an operating state without locking and causing damage when the adjustment gear 310 is locked. The imaging device 10 for a laser realizes automatic observation and acquisition of images in the laser eyepiece, avoiding the inconvenience of manual operation and the problem of low accuracy. It also realizes automatic focusing of the laser eyepiece and adds an adjustment part 320, thereby improving the accuracy of focusing. Furthermore, the setting of the anti-lock mechanism 500 can prevent the motor 410 from locking and being damaged, thereby improving the stability and safety of the device operation.
