Description

Technical Field

[0001] The utility model relates to the technical field of photographic equipment, in particular to a fishing rod-type retractable portable photographic rocker arm. Background Art

[0002] A camera jib is a camera support device widely used in film and television shooting. It is used to achieve a full range of shooting angles and capture shots that are difficult to obtain with traditional camera positions, thereby expanding the shooting space and angle of view. However, existing camera jibs cannot be telescopically adjusted and can only be assembled on-site during shooting. Setting up is troublesome, time-consuming and labor-intensive, and the jib is too bulky and inconvenient to carry. Therefore, we propose a fishing rod-shaped retractable portable camera jib. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the existing technology. The existing photographic rocker arm cannot be telescopically adjusted and can only be assembled on site during shooting. It is troublesome to set up, time-consuming and labor-intensive, and the rocker arm is too bulky and inconvenient to carry.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A fishing rod-type retractable portable photographic jib comprises a folding support frame, an angle adjustment seat is mounted on the top of the folding support frame, and a telescopic arm mechanism is mounted on the angle adjustment seat;

[0006] The telescopic arm mechanism includes a main arm, which is installed on an angle adjustment seat. A servo motor is installed in the main arm near the angle adjustment seat. A screw is provided at the output end of the servo motor. The screw extends into the first telescopic arm and the second telescopic arm. The main arm is located in the first telescopic arm, and the first telescopic arm is located in the main arm. A screw nut is provided at one end of the first telescopic arm near the servo motor, and the screw nut is sleeved on the screw. A spring buckle assembly is provided on the outside of the second telescopic arm near the screw nut. A through hole is provided in the first telescopic arm away from the screw nut, and is adapted to the spring buckle assembly.

[0007] Furthermore, the spring buckle assembly includes a housing shell, a spring is installed in the housing shell, a U-shaped piece is provided around the outer periphery of the spring, and protrusions are provided on both sides of the outer periphery of the U-shaped piece.

[0008] Furthermore, a limit block is provided at one end of the first telescopic arm and the second telescopic arm close to the servo motor.

[0009] Furthermore, an auxiliary telescopic arm is installed on the angle adjustment seat below the main arm, and camera seats are installed at the ends of the second telescopic arm and the auxiliary telescopic arm.

[0010] Furthermore, the auxiliary telescopic arm corresponds to the telescopic arm mechanism and is also provided with a two-stage telescopic rod.

[0011] Furthermore, a counterweight wheel is provided at one end of the telescopic arm mechanism close to the angle adjustment seat, and two counterweight wheels are provided on both sides of the front end of the main arm, and a grip is provided at the center of the counterweight wheel.

[0012] Furthermore, the main arm is provided with a control knob at one end of the counterweight wheel.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The telescopic arm mechanism is activated by turning the adjustment knob at the rear end of the main arm, and the servo motor in the main arm will drive the screw to rotate, driving the screw nut to move toward the front end, so that the first telescopic arm is extended from the main arm. If the arm length is not enough, the end of the second telescopic arm can be pulled to extend. When stretched to a certain length, the spring buckle assembly will pop out and be stuck on the through hole opened in the first telescopic arm, thereby realizing the fixed installation of the rocker arm. Compared with the existing technology, the utility model is simple to install, and the rocker arm is a retractable structure, which is easy to carry. BRIEF DESCRIPTION OF THE DRAWINGS
