[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1-5The utility model provides a technical solution: a camera support frame, including a bracket 1 and a camera base 2, an adjustment mechanism including a slide plate 3, a limit rod 4 and a reciprocating screw rod 5, the slide plate 3 is slidably arranged on the top of the bracket 1, two slide plates 3 are provided, the limit rod 4 is fixedly installed between the two slide plates 3, and the reciprocating screw rod 5 is rotatably installed between the two slide plates 3. The reciprocating screw rod 5 and the limit rod 4 are both sleeved inside the camera base 2, the limit rod 4 and the camera base 2 are slidably connected, and the reciprocating screw rod 5 and the camera base 2 are threadedly connected. The field of view adjustment mechanism is arranged at the top of the bracket 1 for adjusting the field of view of the camera, and by setting the adjustment mechanism, rotating the reciprocating screw rod 5, through the cooperation of the limit rod 4 and the threaded connection between the reciprocating screw rod 5 and the camera base 2, the camera base 2 slides to the right on the bracket 1, and after reaching the limit distance, it slides to the left, and repeats this process, so that the position of the camera base 2 can be adjusted by rotating the reciprocating screw rod 5, so that when the staff installs the bracket 1, even if there is a certain error, the camera base 2 can be adjusted by adjusting the relative position of the camera base 2 and the bracket 1;

[0034] It is worth noting that the bracket 1 is pre-installed at a preset position by bolts. Since the camera is installed on the top of the bracket 1, the camera is installed at the preset position, and the bracket 1 supports the camera to ensure the stability and accuracy of the captured image.

[0035] Reference Figure 1-5 The field of view adjustment mechanism includes a meshing tooth 6 and a gear ring 7. The meshing tooth 6 is fixedly mounted on the top of the bracket 1, and the gear ring 7 is rotatably mounted on one side of the slides 3 close to the camera base 2. The gear ring 7 and the meshing tooth 6 are meshed and connected. By setting the field of view adjustment mechanism, since the slide 3 is slidably arranged on the top of the bracket 1, through the meshing connection between the meshing tooth 6 and the gear ring 7, when the gear ring 7 rotates, it drives the slide 3 to slide on the bracket 1, so that the camera moves forward or backward, thereby adjusting the relative position of the camera base 2 on the bracket 1, so that the staff can freely adjust the viewing angle range of the camera;

[0036] Reference Figure 1-5 A limiting groove 8 is provided at the top of the bracket 1, and a limiting block 9 is slidably installed inside the limiting groove 8. The top of the limiting block 9 is fixedly connected to the bottom of the slide 3. By setting the limiting groove 8 and the limiting block 9, the moving stroke of the slider on the bracket 1 is limited so that the slider can only move forward or backward;

[0037] Reference Figure 1-5, the surface of the reciprocating screw 5 is fixedly sleeved with a swivel 10, which is sleeved inside the gear ring 7. One of the slides 3 is rotatably installed with a gear 11 on the side close to the camera base 2. The gear 11 and the gear ring 7 are meshed and connected. The surface of the swivel 10 is provided with a receiving cavity 12. A wedge 13 is slidably installed inside the receiving cavity 12. A driving block 14 is fixedly installed on the inner wall of the gear ring 7. The shape of one side of the wedge 13 is set to an arc shape, and the surface of the driving block 14 is set to a smooth shape. A motor 16 is fixedly installed on the left side of one of the slides 3. The output end of the motor 16 is fixedly connected to the gear 11. By setting the swivel 10 and the gear 11. Start the motor 16 to rotate the gear 11. Through the meshing connection between the gear 11 and the gear ring 7, the gear ring 7 drives the driving block 14 to rotate. As the driving block 14 rotates, it abuts and squeezes the wedge block 13, causing the swivel 10 to drive the reciprocating screw 5 to rotate, thereby providing driving force for the rotation of the reciprocating screw 5. When the gear 11 rotates in the opposite direction, due to the arc-shaped setting on one side of the wedge block 13, the wedge block 13 is squeezed by the driving block 14 and retracted into the accommodating cavity 12. The swivel 10 cannot drive the reciprocating screw 5 to rotate, so that the staff can adjust the position of the camera base 2 on the bracket 1 separately.

[0038] Reference Figure 1-5 A spring 15 is fixedly installed on the inner wall of the accommodating chamber 12, and the other end of the spring 15 is fixedly connected to the wedge block 13. By setting the spring 15, the wedge block 13 is squeezed and compressed by the driving block 14 into the accommodating chamber 12, and can return to its original position by the rebound force of the spring 15.

[0039] Specifically, the working process or working principle of this camera support is as follows: when in use, the bracket 1 is installed in the preset position by bolts, and the motor 16 is started to rotate the gear 11. The gear 11 and the gear ring 7 are meshed and connected, so that the gear ring 7 drives the driving block 14 to rotate. Since the driving block 14 abuts and squeezes the wedge block 13 when it rotates, the rotating ring 10 drives the reciprocating screw rod 5 to rotate. Through the cooperation of the limit rod 4 and the threaded connection between the reciprocating screw rod 5 and the camera base 2, the camera base 2 slides to the right on the bracket 1, and after reaching the limit distance, it slides to the left, and so on. The position of the camera base 2 can be adjusted by rotating the reciprocating screw 5, and the motor 16 is started in reverse. When the gear 11 rotates in the opposite direction, due to the arc-shaped setting on one side of the wedge 13, the wedge 13 is squeezed by the driving block 14 and retracted into the accommodating cavity 12, and the rotating ring 10 cannot drive the reciprocating screw 5 to rotate. Since the slide plate 3 is slidably set on the top of the bracket 1, it is connected by the meshing teeth 6 and the gear ring 7. When the gear ring 7 rotates, it drives the slide plate 3 to slide on the bracket 1, so that the camera moves forward or backward, so that the relative position of the camera base 2 on the bracket 1 can be adjusted.

[0040] It should be noted that the motor 16 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
