Description

A camera carrying system

technical field

The invention relates to the technical field of photographic and photographic auxiliary equipment, in particular to a photographic and photographic device carrying system.

Background technique

In the prior art, shooting movies and TV usually requires the use of a camera track system at the shooting site. The camera track system generally includes a rail car and a camera track. Or the shooting of the scene to complete the work of photography and videography.

Presently known camera tracks are generally mainly composed of main slide rails, transverse connecting belts, transverse shafts, etc. During use, cameras and tripods are arranged on rail cars, and the characters or scenes are photographed by sliding on rails with rail frames. The horizontal axis of the camera track is set between the two ends of the main slide rail. The main slide rail and the horizontal axis form a fixed frame body. Adjacent transverse shafts are fixedly connected by transverse connecting belts. During use, it is necessary to lay a track matching the track wheel pitch on the ground, and then set the pulley of the rail car in the main slide rail to realize the movement of the rail car.

However, the problem in the prior art is that the horizontal axis is a fixed rod with a fixed length, so the gauge of the main slide rail is limited. Since the gauge is fixed, a set of tracks is only suitable for railcars with corresponding wheelbases. Other alternative rail car carriers with wheels are not available. Moreover, since the gauge of the track is fixed, if a tripod is used to set it directly on the track or on a rail car, its width will be limited due to the fixed track, making it impossible to achieve low-angle shooting with a small width. And in some conferences and gathering occasions, it is also not convenient to use this type of camera track to take pictures and take photos on the spot.

The existing rail cars need to be purchased separately, and the rail cars cannot match all the camera tracks. Rail cars of different gauges need to be matched with the corresponding camera tracks. The waste of resources is serious, and multiple rail cars and camera tracks are required. The cost of shooting is high.

Moreover, in addition to setting up a camera track with a set distance at the shooting site and using a camera track car corresponding to the camera track for shooting movies and TV, after the shooting is completed, the photography and camera equipment need to be stored in the camera track equipment box. In order to carry and move the camera track equipment box conveniently, the camera track equipment box in the prior art generally includes a box body and a pulley mechanism arranged at the bottom of the box body. The pulley mechanism includes four universal wheels, and four universal wheels are set. The purpose of the wheels is to facilitate the movement of the drive box. When in use, just push the box body, and the camera track equipment box can be moved conveniently through the movement of the universal wheels. However, the camera track equipment box only plays the role of storing photography and video equipment, and its application range is narrow, its use function is single, and its utilization rate is low, so it cannot give full play to its effect.

Therefore, in view of the deficiencies in the prior art, it is urgently necessary to provide a rail-carrying technology for photographing and imaging devices that is easy to use, adjustable in gauge, and has a wide range of applications to overcome the deficiencies in the prior art.
