A three-axis pan-tilt head for a camera

Abstract

This utility model relates to the field of mechanical equipment technology and discloses a three-axis pan-tilt head for a camera, including a mounting plate. An adjustment component is provided at the bottom of the mounting plate, and a U-shaped plate is provided on the right side of the adjustment component. A camera body is disposed inside the U-shaped plate, and a limiting component is provided on the outer wall of the camera body. The limiting component includes an L-shaped support plate, an L-shaped limiting plate, a U-shaped pressure plate, a rubber pad, and an L-shaped locking rod. This utility model installs the camera body in two L-shaped support plates, with the L-shaped limiting plate limiting the position of the camera body. After installation, the rubber pad presses firmly against the top of the camera body. When maintenance is required, pulling the connecting rod causes the L-shaped locking rod to disengage from its slot, releasing the U-shaped pressure plate and allowing it to move upwards. After moving upwards, the released L-shaped locking rod is inserted into another slot to lock the U-shaped pressure plate, thus allowing the camera body to be removed for maintenance. The operation is simple and improves maintenance efficiency.

Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a three-axis gimbal for a camera. Background Technology

[0002] A pan-tilt head is a support platform used to mount load devices, typically imaging devices such as cameras and camcorders. When the imaging device is fixed on the pan-tilt head, its position and angle can be changed by moving the imaging device through the pan-tilt head, thereby achieving active tracking and positioning of the target being photographed.

[0003] According to Chinese Patent Publication No. CN208855880U, a three-axis gimbal includes a mounting platform, a yaw motor, a roll motor, a pitch motor, a first bracket, a second bracket, and a camera. The yaw motor is mounted on the mounting platform. The pitch motor and roll motor are connected to both ends of the first bracket, and the roll motor and yaw motor are connected to both ends of the second bracket. The camera is connected to the pitch motor. The first bracket is tilted outward toward the mounting platform, and the angle formed between the first bracket and the mounting platform is 10° to 45°, which allows the pitch motor to... After the camera head rotates to the back of the three-axis gimbal, its view is not obstructed. This allows the camera lens to automatically rotate to the back of the three-axis gimbal for shooting scenic spots, driven by the pitch motor. This eliminates the need for the drone to rotate to reach the scenic spot behind the three-axis gimbal, reducing shooting limitations and expanding the shooting scenarios. The above technology involves mounting the camera inside the bracket for shooting, but it is inconvenient to disassemble the camera. If the camera needs maintenance, it will cause inconvenience to maintenance personnel. Therefore, a three-axis gimbal for cameras is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a three-axis gimbal for a camera, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a three-axis pan-tilt head for a camera, including a mounting plate, an adjustment component at the bottom of the mounting plate, a U-shaped plate on the right side of the adjustment component, a camera body inside the U-shaped plate, and a limiting component on the outer wall of the camera body. The limiting component includes an L-shaped support plate, an L-shaped limiting plate, a U-shaped pressure plate, a rubber pad, and an L-shaped locking rod. The L-shaped support plate is located inside the U-shaped plate, the L-shaped limiting plate is connected to the left side of the L-shaped support plate, the U-shaped pressure plate is slidably connected to the L-shaped support plate, the rubber pad is connected to the top of the inner wall of the U-shaped pressure plate and abuts against the top of the camera body, a slot is opened on the right side of the U-shaped pressure plate, and one end of the L-shaped locking rod is inserted into the slot.

[0006] Preferably, there are two L-shaped support plates, two L-shaped limiting plates, and two L-shaped locking rods. The camera body is placed inside the two L-shaped support plates, and there are four locking slots on the U-shaped pressure plate.

[0007] Preferably, both L-shaped support plates are provided with guide holes, and the inner wall of the U-shaped pressure plate is connected to two sliders, which are slidably connected in the two guide holes respectively.

[0008] Preferably, a connecting rod is connected between the two L-shaped levers, and two connecting blocks are connected to the top of the connecting rod.

The two round rods are slidably connected in the two round grooves respectively, and a spring is provided in each of the two round grooves.

[0009] Preferably, a limiting mechanism is provided on the right side of the U-shaped pressure plate, the limiting mechanism including an L-shaped frame connected to the right side of the U-shaped pressure plate.

[0010] Preferably, the L-shaped frame is threaded with a lead screw, and the two ends of the lead screw are respectively connected to a rotating block and a pressing block.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. This camera uses a three-axis pan-tilt head. The camera body is installed in two L-shaped brackets, and the L-shaped limiting plates restrict the placement of the camera body. After installation, the rubber pad presses the top of the camera body. When maintenance is required, the connecting rod is pulled to move the L-shaped locking rod out of the slot, so that the U-shaped pressure plate is released from its restriction and then moved upward. After moving upward, the released L-shaped locking rod is inserted into another slot to lock the U-shaped pressure plate, so that the camera body can be removed for maintenance.

[0019] like Figure 1-3As shown, this utility model provides a three-axis pan-tilt head for a camera, including a mounting plate 1. An adjustment assembly 2 is located at the bottom of the mounting plate 1, and a U-shaped plate 3 is located on the right side of the adjustment assembly 2. A camera body 4 is housed inside the U-shaped plate 3, and a limiting assembly 5 is provided on the outer wall of the camera body 4. The limiting assembly 5 includes an L-shaped support plate 51, an L-shaped limiting plate 52, a U-shaped pressure plate 53, a rubber pad 54, and an L-shaped locking rod 55. The L-shaped support plate 51 is located inside the U-shaped plate 3, the L-shaped limiting plate 52 is connected to the left side of the L-shaped support plate 51, the U-shaped pressure plate 53 is slidably connected to the L-shaped support plate 51, the rubber pad 54 is connected to the top of the inner wall of the U-shaped pressure plate 53 and abuts against the top of the camera body 4, a slot is provided on the right side of the U-shaped pressure plate 53, and one end of the L-shaped locking rod 55 is inserted into the slot. Mounting holes are provided on the mounting plate 1 for easy bolt fixing. In appropriate positions, there are two L-shaped support plates 51, two L-shaped limiting plates 52, and two L-shaped locking rods 55. The camera body 4 is placed inside the two L-shaped support plates 51. The U-shaped pressure plate 53 has four slots. The four slots are designed to match the two L-shaped locking rods 55. The four slots are arranged in pairs on the front and rear sides of the camera body 4. When fixing the camera body 4, the L-shaped locking rods 55 are inserted into the upper slot. A connecting rod 56 connects the two L-shaped locking rods 55. Two connecting blocks 57 are connected to the top of the connecting rod 56.
