[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:
[0022] like Figure 1 As shown, this utility model provides a multi-angle auxiliary adjustment device for a bullet camera, including a fixed bracket 1, a rotating seat 2 fixedly connected to the rear of the fixed bracket 1, a rotating seat 5 rotatably connected to the rear of the rotating seat 2, a rotating platform 3 rotatably connected to the rear of the rotating seat 5, a base 4 rotatably connected to the rear of the rotating platform 3, and a driving device 6 fixedly connected inside the rotating platform 3.
[0023] like Figure 2 As shown, this utility model provides a technical solution: a synchronous pulley 62 is fixedly connected to the left side of a rotating base 2 on a rotating base 2 on a rotating base 5. A synchronous pulley 63 is rotatably connected to the rear of the synchronous pulley 62 on the rotating base 2 on a rotating base 5. The synchronous pulley 63 and the synchronous pulley 62 are driven by a synchronous belt. The synchronous pulley 63 is rotatably connected to the rotating base 2 on a rotating base 2 on a rotating base 5. A bevel gear 64 is fixedly connected to the right side of the synchronous pulley 63. A housing 61 is fixedly connected to the left side of the synchronous pulleys 62 and 63 on the rotating base 2 on a rotating base 5. When the synchronous pulleys 63 and 62 rotate, the fixed connection between the synchronous pulley 62 and the rotating base 2 drives the rotating base 2 and the camera in front to complete the up and down tilting motion.
[0024] like Figure 3As shown, this utility model provides a technical solution: a bevel gear 65 meshes above a bevel gear 64, a spur gear 610 is fixedly connected above the bevel gear 65, a drive shaft 612 is fixedly connected to the right side of a rotating seat 5 on the bevel gear 65, a sliding groove is provided on the drive shaft 612 above the rotating seat 5 and a locking tongue 67 is slidably connected thereto, a spring 68 is fixedly connected above the locking tongue 67, both the upper and lower ends of the drive shaft 612 are rotatably connected to a rotating platform 3, a double toothed ring 69 is rotatably connected to the outside of the drive shaft 612 on the rotating platform 3, the internal gear of the double toothed ring 69 and the locking tongue 67 are both meshed with the spur gear 610, and the outside of the drive shaft 612... A fixed base 613 is rotatably connected, and a guide post 625 is slidably connected inside the fixed base 613. A slide table 611 is fixedly connected above the fixed base 613. A push plate 66 is fixedly connected in front of the slide table 611. When it is necessary to adjust the vertical angle of the rotating seat 2, the electric push rod 628 is activated and pushes the slide table 611 to the farthest end. At this time, the push plate 66 in front of the slide table 611 pushes the locking tongue 67 to move upward, disengaging from the spur gear 610. The spring 68 is compressed and stores energy. The outer toothed ring of the double toothed ring 69 gradually meshes with the spur gear 627, forming a new transmission path and releasing the vertical rotation lock of the rotating seat 2.
[0025] like Figure 4As shown, this utility model provides a technical solution: a locking tongue 624 is fixedly connected below the transmission shaft 612, a slide 616 meshes below the locking tongue 624, a spur gear 615 is rotatably connected above the slide 616, and a spur gear 617 is rotatably connected below the spur gear 615. The spur gear 617 meshes with the spur gear 615, a spur gear 618 meshes below the spur gear 617, a motor 619, the power source of the spur gear 618, is fixedly connected above the spur gear 618, the motor 619 is fixedly connected to a fixed base 613, a bevel gear 620 is rotatably connected below the fixed base 613, a bevel gear 621 meshes above the bevel gear 620, a spur gear 623 is fixedly connected above the bevel gear 621, and a spur gear 623 is rotatably connected above the spur gear 623. There is a fixed seat 2 622, and a locking tongue 2 624 is engaged on the left side of the spur gear 623. The spur gear 7 626 is rotatably connected below the slide 1 611. The spur gear 8 627 is engaged in front of the spur gear 7 626. The spur gear 7 626 and the spur gear 4 617 are fixedly connected. When it is necessary to adjust the left and right angle of the rotating seat 1 2, the electric push rod 628 pulls the slide 1 611 to the innermost side, and the slide 2 616 gradually moves away from the spur gear 2 614, so that the spur gear 2 614 engages with the spur gear 3 615. At the same time, the slide 1 611 drives the spur gear 8 627 away from the double toothed ring 69. At the same time, the spring 68 releases energy, pushes the locking tongue 1 67 to reset and re-engage the spur gear 610, and locks the up and down angle of the rotating seat 1 2. While releasing the left and right rotation lock of the rotating seat 2 5, the upper and lower shafts are locked to avoid multi-axis interference.
[0026] like Figure 5 As shown, this utility model provides a technical solution: an electric push rod 628 is fixedly connected to the lower part of the fixed base 613, the push rod of the electric push rod 628 is fixedly connected to the slide table 611, a spur gear 629 is fixedly connected to the rear of the bevel gear 620, and an internal gear ring is provided in front of the rotating base 5 and meshes with the spur gear 629. When the spur gear 629 rotates, because the spur gear 629 meshes with the internal gear ring in front of the rotating base 5, it will drive the rotating base 5 to rotate around the base 4, thereby realizing the roll adjustment of the camera.
[0027] The working principle of the multi-angle auxiliary adjustment device for this bullet camera will be explained in detail below.
[0028] like Figure 1-5As shown, when it is necessary to adjust the vertical angle of the rotating seat 2, the electric push rod 628 is activated and pushes the slide 611 to its farthest end. At this time, the push plate 66 in front of the slide 611 pushes the locking tongue 67 upward, disengaging it from the spur gear 610. The spring 68 is compressed and stores energy. The outer toothed ring of the double toothed ring 69 gradually meshes with the spur gear 627, forming a new transmission path and releasing the vertical rotation lock of the rotating seat 2. After the motor 619 is started, the power is transmitted to the spur gear 617 through the spur gear 618, and then to the spur gear 627 through the spur gear 626. The spur gear 627 then drives the double toothed ring 69 to rotate, which in turn drives the bevel gear 627 through the bevel gear 618 meshing with it. 65. Bevel gear 64 drives synchronous pulleys 63 and 62 to rotate. Synchronous pulley 62 is fixedly connected to rotating seat 2. Its rotation causes rotating seat 2 and the front camera to tilt up and down. When it is necessary to adjust the left and right angle of rotating seat 2, electric push rod 628 pulls slide 611 to the innermost side. Slide 616 gradually moves away from spur gear 614, so that spur gear 614 meshes with spur gear 615. At the same time, slide 611 drives spur gear 627 away from double toothed ring 69. Spring 68 releases energy, pushing locking tongue 67 to reset and re-engage spur gear 610, locking the up and down angle of rotating seat 2. While locking the left and right rotation of the rotating base 25, the upper and lower shafts are also locked to prevent multi-axis interference. Then, the motor 619 is started. The power of the motor 619 is transmitted to the drive shaft 612 through spur gear 5 618 → spur gear 4 617 → spur gear 3 615 → spur gear 2 614. At the same time, the drive shaft 612 is locked to the rotating base 25. Its rotation will drive the rotating base 25 and the camera to complete the left and right horizontal rotation. When the rotating base 12 needs to rotate, the electric push rod 628 moves the slide 1 611 to the middle position. The slide 1 611 drives the locking tongue 2 624 and the spur gear 7 626 to move. At this time, the locking tongue 1 67 remains locked, and the spur gear 2 614 meshes with the slide 2 616. Gear 623 unlocks from locking tongue 2 624 and engages with spur gear 7 626, unlocking only the rotation function of rotating base 2 5. Then, motor 619 is started. The motor power is transmitted through spur gear 5 618 → spur gear 4 617 → spur gear 7 626 → spur gear 623, and then through bevel gear 4 621 and bevel gear 3 620 to spur gear 9 629. Spur gear 9 629 engages with the internal gear ring in front of rotating base 2 5, driving rotating base 2 5 to rotate around base 4, realizing the roll adjustment of the camera. Electric push rod 628, as the actuator for transmission switching, moves by pushing and pulling slide 1 611 to change the meshing state of the gear set, so that the power of single motor 619 flows to different axes.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
