Description

1. TECHNICAL FIELD The invention relates to the technical field of robotic arms, and specifically refers to a mobile photography shock absorption system. 2. BACKGROUND ART When moving the lens indoors or outdoors to shoot sports scenes, in order to keep the images captured by the camera stable and smooth, it is usually necessary to use some camera shock absorption devices to maintain the stability of the images captured by the camera. In the prior art, the shock absorption device for cameras usually uses springs as buffering and energy absorption components. Using springs as buffering components has the following disadvantages: 1. when the shock absorption device needs to be adapted to machines of different weights, the springs usually need to be replaced, and the springs on both sides of the shock absorption device need to be adjusted to the same tightness; replacing the springs is time-consuming and laborious; 2. the life of the springs is limited; after a period of high-frequency use, stress relaxation occurs easily, resulting in poor stability. 3. SUMMARY OF THE INVENTION In order to solve the above technical problems, the technical solutions provided by the invention are: a mobile photography shock absorption system, comprising a shock absorption arm main body and a shock absorption head, and the shock absorption head is connected to the shock absorption arm main body; the shock absorption arm main body is installed with a shock absorber, and the end of the shock absorption arm main body is installed with an image transmission bracket; the lower part of the image transmission bracket is installed with a horizontal shock absorption head, and the bottom of the horizontal shock absorption head is installed with a suspension shock absorption system; the shock absorption arm main body is detachably connected with a double-sided dovetail slide plate; the double-sided dovetail slide plate is detachably connected with a first dovetail slider, a second dovetail slider, and a third dovetail slider; the shock absorption arm main body is connected to the double-sided dovetail slide plate through the first dovetail slider; the second dovetail slider is installed with an angle rotation connecting rod bracket, and the end of the angle rotation connecting rod bracket away from the second dovetail slider is installed with a plurality of first suction cups; the third dovetail slider is installed with a plurality of second ball journal suction cups; the first suction cups and the second ball journal suction cups are used to fix the above mobile photography shock absorption system. Further, the shock absorber is a coiled spring shock absorber or other elastic object. Further, the first dovetail slider, the second dovetail slider, and the third dovetail slider have the same structure, and the first dovetail slider is provided with a detent rod and a detent pin. Further, the first suction cup and the second ball journal suction cup have the same structure, and both are provided with two groups; a connecting crossbar is installed between the two groups of first suction cups, and the connecting crossbar is provided with a handle and a lock nut; the first suction cup is provided with three structures. The advantages of the invention compared with the existing technology are: The invention adopts a combination of multiple structures such as a shock absorption arm main body, a shock absorption head, a shock absorber, a double-sided dovetail slide plate, dovetail sliders, suction cups, and an angle rotation connecting rod bracket to provide a mobile photography shock absorption system. The above shock absorption system can be used for mobile shooting in the fields of cars, motorcycles, airplanes and boats, etc. The above structure can be applied to camera equipment of different weights, saving more time and effort. On the other hand, compressed air is used to buffer and absorb energy, without the problem of stress relaxation and reduced shock absorption effect like springs. The rear of the arm is optionally equipped with a hydraulic rebound buffer to relieve the force of the large upward swing of the arm. Various brackets can be fixed at multiple angles and dimensions, which solves the problem that the static fixed torque of the locked joint does not decay under the condition of long-term use and wear. Two axial angle adjustments can be added through a 90-degree adapter. 4.
