Background

The illuminating lamp is a lamp for improving the ambient brightness in high-speed photography, and can help the high-speed camera to more clearly capture a shot object and improve the definition of a shot picture. Because the light volume that is used for high-speed photography is great, be unfavorable for handheld or with the tripod support, and because the reason that test equipment and place were arranged, high-speed camera often will use in the room, and the light needs the not co-altitude, the shining of multi-angle when using in addition, adopts fixed supporting platform can't realize regulatory function. Therefore, a movable and lockable bracket capable of adjusting the height and the irradiation angle of the illuminating lamp simultaneously is needed. However, because the illuminating lamp is heavy and bulky, the traditional tripod is difficult to provide stable support, and the traditional tripod has the risks of shaking and falling, thereby influencing the test process and the high-speed photographing effect.

At present, the lighting lamp support in the domestic existing, such as a novel tripod structure lamp support disclosed in chinese invention patent CN214501140U, provides a lighting lamp support with adjustable height and angle, but is only suitable for a small lighting lamp for general photography and shooting, and cannot support a high-speed photography lighting lamp with large volume and weight. Also like the photographic lamp bracket disclosed in chinese patent No. CN108279544A, the fixing bracket is adopted to ensure the stability of the illuminating lamp and maintain the positioning accuracy, but the height adjustment is difficult to achieve after the lamp body is fixed, and the portability is greatly impaired. Therefore, the bracket of the high-speed photographic illuminating lamp at the present stage is difficult to meet the requirements of adjustable height and angle and multiple functions of portability, movability and random locking. Therefore, a high-speed camera lighting lamp bracket needs to be developed to meet the use requirements of users.

Preferably, the method further comprises:

and the suspension plate is fixedly arranged on the suspension frame cross arm, and the suspension head is arranged on the suspension plate.

Preferably, the base is formed by intersecting a plurality of support legs, and the adjacent support legs are connected through a triangular connecting piece.

Preferably, the support legs are made of a 4040 aluminum profile in national standard.

Preferably, the material of mounted frame is national standard 2020 aluminium alloy.

The invention has the following beneficial effects: when the high-speed camera shooting illuminating lamp support is used for an illumination test, the height and the angle of the suspension bracket can be conveniently adjusted and fixed through the matching, the rotation and the locking of the screw rod and the nut on the high-speed camera shooting illuminating lamp support, meanwhile, the high-speed camera shooting illuminating lamp support can be conveniently moved to any position by utilizing the universal wheel and the support leg, the foot lock can realize the quick locking of the high-speed camera shooting illuminating lamp support, and the dead-angle-free illumination of shooting objects at different heights and directions is realized; the test device has the advantages that the test device is convenient for experiment technicians to use, the test efficiency is improved, and the time is saved. This stabilizer blade and mounted frame of high-speed light support of making a video recording have adopted aluminum alloy ex-trusions, corner fittings and T type bolted connection to become an organic whole, and the quality is little, easily makes, is convenient for remove and carry, is applicable to the test under the multiple occasion.
