Description

The general rocking arm of the big small camera of portable broadcast level

Affiliated technical field

The utility model belongs to image production equipment technical field, relates to a kind of video camera rocker arrangement that is used in the on-the-spot supporting video camera work of production.

Background technology

At present having complex structure heaviness, cost height, carry inconvenience in various degree, the incompatible video camera that varies in size, both sides control lever can not be adjusted the locus flexibly in real time according to environment in actual applications for known various types of video camera rocker arrangements both at home and abroad, defectives such as area occupied is big, the stretching-resisting bending-resisting intensity of its armed lever connection place is low, generally need big mouthful through tubing and wire rope support, can use safely.In addition, when existing rocker arrangement uses at the production environment of different sizes (forearm length 1～6 meter time), all need prepare the wire rope (every group of 3～4 wire rope) of 1～6 meter many groups of different length, with stretching armed lever and draw control The Cloud Terrace level, formality is numerous and diverse, and adaptive capacity to environment is poor.When rocking arm is installed, existing rocker arrangement only depends on counterweight to regulate, be difficult for accomplishing best balance, therefore forearm must be put three-legged support, like this when operation, the operator just has to hold the both sides control lever very arduously in whole process, can not loose one's grip during this time, otherwise just can not real-time positioning take, so operating personnel are very easily tired, again because on the monitor installation armed lever or on the control lever, it quite feels inconvenience when the operation rocking arm moves up and down, when monitor rocking arm up and down wide-angle when motion observe more inconvenient so that the video camera with pre-prison signal output not is difficult to accomplish that remote control is recorded accurately, the accident of by mistake recording mistakenly stop very easily takes place.

The utility model content

Be the problem that prior art exists is solved order of the present utility model, so provide a kind of novelty simple in structure, easy to carry, installing/dismounting is laborsaving fast, the general rocking arm of the big small camera of portable broadcast level of the directly perceived and easily-learned easily mastered of flexible operation.

The technical solution that adopts is so for achieving the above object: the general rocking arm of the big small camera of portable broadcast level that is provided has a company and is contained in the U type The Cloud Terrace of regulating on the tripod, U template both sides at U type The Cloud Terrace are respectively equipped with monitor fabricated section and video recorder fabricated section, connect respectively in the front-end and back-end of U template rocking lever and extendable weight loop bar are housed, said rocking lever is connected to form by the aluminum alloy square tube that more piece top has U type groove, connects by the The Cloud Terrace regulating shaft at the front end of rocking lever the camera pan-tilt of being united driving by left rotation and right rotation motor and last lower rotating electrical machine is housed; The square tube that moved the location before and after said extendable weight loop bar can be done in the square tube sleeve by a U type groove square tube sleeve and one constitutes, and connects by the counterweight connection seat in the rear end of square tube carry battery case, remote controller box, angle control lever and bar device for regulating rotary are housed.

With prior art products relatively, that general rocker arrangement described in the utility model has is simple in structure, multiple functional, compact, firm safe, good and cheap, floor area is little, practical and convenient, be used in combination comfortable advantage such as arbitrarily.The compatibility of this rocker arrangement is strong, various brands on market sizes broadcast level, professional video camera all can general (various brands video camera control line be matched voluntarily) so far, monitor can rotate synchronously with operating personnel during operation, be not subjected to rocking arm image up and down, can make operating personnel remain best viewing angle; Image that can be observed in the work according to monitor, by remote controller box, the operating rock arm pitching moves flexibly, and can regulate and control two groups of motors individually or simultaneously and do 360 degree motion rotations up and down, stepless speed regulation is carried out combined type of all shapes and colors and is taken, and makes picture have stronger artistic appreciation; The counterweight loop bar of establishing behind the U type The Cloud Terrace (square tube) can move forward and backward in counterweight sleeve (square tube sleeve), the extendable weight loop bar is changed with rocking arm length adjust, and regulates length and counterweight, is beneficial to the utilization and the best counterweight ratio in space.All members of this rocker arrangement are all quick assembly (can arbitrarily assemble) between 1～6 meter, be easy to dismounting, convenient transportation, and the taxi of a band boot both can pull away a complete set of rocker arrangement and 2～3 people simultaneously.In addition, this rocker arrangement carries the system power supply device, and the assurance instrument reaches in the open air in the various occasions and works long hours easily, is very suitable for occasions such as party scene, scenic film, MTV, documentary film, TV play and uses.
