Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to a dual-axis turntable optical closed-loop tracking coarse tracking support. Background Technology

[0002] A bracket is a common support structure in daily life. It is a temporary structure used to support objects, equipment, and people. It can also be used to fix and hold equipment components in place. For example, the metal bracket inside electronic devices can be used to fix circuit boards or other components.

[0003] When the support is applied in the field of optics, since human reaction time and endurance are insufficient to support continuous operation of the telescope until the target to be captured appears, it is necessary to enable the support to automatically capture the target and move the lens according to the required optical information to achieve automatic tracking. Therefore, a dual-axis turntable optical closed-loop tracking coarse tracking support is required.

[0004] The existing dual-axis turntable optical closed-loop tracking coarse tracking bracket has the following shortcomings:

[0005] Currently available dual-axis turntable optical closed-loop tracking coarse tracking brackets can automatically, quickly, and accurately capture targets in practical applications. However, when the target moves too fast, the turning mechanism moves the lens in an instant. Due to the poor stability of the bracket itself, the lens becomes unstable, resulting in blurred images of the observed objects. Since the target often only has one chance to be observed, this can lead to irreparable losses.

[0006] Therefore, we propose a dual-axis turntable optical closed-loop tracking coarse tracking bracket to solve the problems mentioned above. Utility Model Content

[0007] Rotate the handle to make the threaded nail perpendicular to the ground. The spring slider engages the gear shaft to maintain stability. Move the rotating bar to be perpendicular to the threaded nail and rotate it in the direction of the thread to insert and fix the threaded nail into the ground, thereby enhancing the stability of the bracket. Adjust the bracket legs to the appropriate position, pull open the fixing rod, and tighten the nut to make the slide rail fit tightly with the second fixing rod, thereby fixing the bracket legs to improve stability, prevent the equipment from shaking and shifting, and ensure the capture and tracking lens, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a dual-axis turntable optical closed-loop tracking coarse tracking bracket, comprising a bracket leg, wherein the bracket leg has an internal shaft hole, and a plurality of spring sliders are fixedly connected to the inner side of the shaft hole. A locking gear shaft is rotatably connected to the inner side of the plurality of spring sliders, and a handle is fixedly connected to the outer side of the locking gear shaft. A rotating block is rotatably connected to the inner side of the bracket leg, and the rotating block is fixedly connected to the locking gear shaft. A threaded pin is provided inside the rotating block, and the threaded pin is threadedly connected to the rotating block. A rotating rod is rotatably connected to the top of the threaded pin, and a fixing mechanism is provided on the outer side of the bracket leg.

[0009] Preferably, the fixing mechanism includes a first fixing rod, which is fixedly connected to the inner side of the support leg. A slide rail is provided on the inner side of the first fixing rod, and a fastening screw is slidably connected to the inner side of the slide rail. A second fixing rod is fixedly connected to the rear side of the fastening screw, and a screw cap is provided on the outer side of the fastening screw. The screw cap is threadedly connected to the fastening screw, and the other end of the second fixing rod is fixed to the support leg.

[0010] Preferably, a central shaft is rotatably connected to the top of the support leg, and a horizontal turntable is rotatably connected to the top of the central shaft.

[0011] Preferably, a longitudinal turntable is fixedly connected to the top of the transverse turntable, and a rotating plate is rotatably connected to the inner side of the longitudinal turntable.

[0012] Preferably, a frame is fixedly connected to the top of the rotating plate, and a target switching platform is fixedly connected to the top of the frame.

[0013] Preferably, two connecting blocks are fixedly connected to the outer side of the platform, and a parallel light tube is fixedly connected to the outer side of the two connecting blocks. A fixing frame is fixedly connected to the other side of the platform, and a coarse tracking sensor is fixedly connected to the inner side of the fixing frame.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, after the bracket and equipment are installed, the operation begins. First, the three bracket legs are opened. Referring to the parameters of the level on the central axis, the position of the bracket legs is adjusted so that the central axis is horizontal with the ground. The handle is turned to drive the rotating block and the threaded nail to rotate until the threaded nail is perpendicular to the ground. The engagement of the spring slider and the engaging gear shaft stabilizes the adjusted angle and increases the stability of the mechanism. The rotating bar on the threaded nail is turned to rotate until it is perpendicular to the threaded nail. Then, the rotating bar is turned in the direction of the thread to suspend the threaded nail to the ground, which enhances the stability of the bracket, effectively controls the rotating equipment, and prevents the equipment from shaking and deviating, thus avoiding missing the capture and tracking lens.

[0016] 2. In this utility model, when the support leg is adjusted to a suitable position, the first and second fixing rods on it are pulled apart. By turning the nut, it rotates inward along the thread of the fastening screw, reducing the space between the nut and the fastening screw until the slide rail and the second fixing rod are tightly fitted, thereby fixing the support legs at both ends to enhance the stability of the support and further reduce the possibility of equipment shaking.

However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as shown in the attached document Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a dual-axis turntable optical closed-loop tracking coarse tracking bracket includes a bracket leg 1. The bracket leg 1 has an internal shaft hole 3. Multiple spring sliders 4 are fixedly connected to the inner side of the shaft hole 3. Engaging gear shafts 5 are rotatably connected to the inner side of the multiple spring sliders 4. A handle 9 is fixedly connected to the outer side of the engaging gear shaft 5. A rotating block 6 is rotatably connected to the inner side of the bracket leg 1. The rotating block 6 is fixedly connected to the engaging gear shaft 5. A threaded pin 7 is provided inside the rotating block 6. The threaded pin 7 is threadedly connected to the rotating block 6. A rotating rod 8 is rotatably connected to the top of the threaded pin 7. A fixing mechanism 2 is provided on the outer side of the bracket leg 1.

[0025] The overall effect of embodiment 1 is as follows: the spring slider 4 is laid in the shaft hole 3, so that the engaging gear shaft 5 is automatically limited without needing to rotate, preventing dimensional deviation. The handle 9 can better rotate the engaging gear shaft 5 in the engaging state. The rotating block 6 is used to fix the threaded nail 7 and drive it to adjust its angle. The rotating rod 8 is used to turn the threaded nail 7, so that the threaded nail 7 can be better inserted into the ground.

[0026] Example 2, as Figure 2 and Figure 3 As shown, the fixing mechanism 2 includes a first fixing rod 201, which is fixedly connected to the inner side of the support leg 1. A slide 202 is provided on the inner side of the first fixing rod 201. A fastening screw 203 is slidably connected to the inner side of the slide 202. A second fixing rod 205 is fixedly connected to the rear side of the fastening screw 203. A screw cap 204 is provided on the outer side of the fastening screw 203. The screw cap 204 is threadedly connected to the fastening screw 203. The other end of the second fixing rod 205 is fixed to the support leg 1.

[0027] The effect achieved by the entire embodiment 2 is as follows: the fastening screw 203 is placed in the slide 202, and the space is reduced by the engagement between the fastening screw 203 and the slide 202, thereby fixing the first fixing rod 201 and the second fixing rod 205.

[0028] Example 3, as Figure 1 and Figure 2 As shown, a central shaft 10 is rotatably connected to the top of the support leg 1, a horizontal turntable 11 is rotatably connected to the top of the central shaft 10, a vertical turntable 12 is fixedly connected to the top of the horizontal turntable 11, a rotating plate 19 is rotatably connected to the inner side of the vertical turntable 12, a platform 17 is fixedly connected to the top of the rotating plate 19, a target switching platform 18 is fixedly connected to the top of the platform 17, two connecting blocks 16 are fixedly connected to the outer side of the platform 17, a parallel light tube 15 is fixedly connected to the outer side of the two connecting blocks 16, a fixed frame 13 is fixedly connected to the other side of the platform 17, and a coarse tracking sensor 14 is fixedly connected to the inner side of the fixed frame 13.

[0029] The effect achieved by the entire embodiment 3 is as follows: the servo motor in the central shaft 10 can drive the horizontal turntable 11 on it to rotate, the vertical turntable 12 has another servo motor that drives the rotating plate, the rotating plate 19 is used to drive the platform 17 on it to rotate, the platform 17 is used to fix each device, the target switching platform 18 can easily replace the device, the coarse tracking sensor 14 can realize the identification of the target, thereby transmitting the signal to each turntable, and then driving the device to rotate through the turntable.

[0030] The working principle of the entire device is as follows: When the support and related equipment are installed and the device begins to work, firstly, the three support legs 1 are opened. Referring to the parameters of the level on the central shaft 10, the positions of the three support legs 1 are precisely adjusted so that the central shaft 10 is level with the ground. Because the support legs 1 have shaft holes 3, multiple spring sliders 4 are laid on the inner surface of the shaft holes 3, and the inner side of the multiple spring sliders 4 has engaging gear shafts 5. The engaging gear shafts 5 are connected to rotating blocks 6 and handles 9. The rotating blocks 6 have threaded pins 7. At this time, rotating the handle 9 will drive the rotating blocks 6 to rotate. Block 6 and threaded nail 7 rotate until threaded nail 7 is perpendicular to the ground. Due to the engagement of spring slider 4 and engaging gear shaft 5, the angle will not easily change after it is adjusted, which also makes the mechanism more stable. At this time, the rotating rod 8 on threaded nail 7 is turned to rotate it to be perpendicular to threaded nail 7. Then, the rotating rod 8 is rotated according to the thread direction on threaded nail 7 to suspend threaded nail 7 to the ground, which makes the bracket more stable and can effectively control the rotating equipment on it, preventing the equipment from shaking and deviating due to its rotational inertia, thus missing the capture and tracking image.

[0031] When the support leg 1 is adjusted to the appropriate position, the first fixing rod 201 and the second fixing rod 205 fixed thereon are pulled apart. Since the first fixing rod 201 has a slide rail 202, the fastening screw 203 fixed to the second fixing rod 205 slides in the slide rail 202. Since the fastening screw 203 has a nut 204 on its external thread, by turning the nut 204, the nut 204 rotates inward along the thread on the fastening screw 203, reducing the space between the nut 204 and the fastening screw 203, until the slide rail 202 and the second fixing rod 205 are tightly fitted together. This achieves the purpose of fixing the support legs 1 at both ends, making the support more stable and further reducing the possibility of shaking.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
