Tripod

Abstract

Disclosed is a tripod, comprising a central disc (1) and three legs (2), with the legs (2) being formed by means of several sleeved segments of pipe fittings (3), and the legs (2) thickening gradually from top to bottom. Such a design can not only improve the extension or retraction speed of the legs by means of fully utilizing the weight of the end segment pipe itself of the legs, but can also reduce the diameter of the central disc, and lower the centre of gravity of the tripod so as to improve the stability.

Description

technical field [0001] The invention relates to a tripod for a camera and a video camera. Background technique [0002] Such as figure 1 , figure 2 As shown, most of the tripod legs that are widely used in the world are aluminum alloy tubes or carbon fiber tubes. What they have in common is that the top is thick and the bottom is thin, except that it is already heavy on the top and light on the bottom, and the center of gravity is too high. In addition to the defects, when it is mounted on the camera, the center of gravity is even higher, such as figure 1 As shown, the height H1 of its center of gravity G1 is almost close to the position of the center plate 1, plus some actions of the photographer when operating the camera, such as dialing, pulling, and pressing, will be transmitted to the farthest and thinnest part. knots, resulting in tremors that affect photography.

Problems solved by technology

[0002] like figure 1 , figure 2 As shown, most of the tripod legs that are widely used in the world are aluminum alloy tubes or carbon fiber tubes. What they have in common is that the top is thick and the bottom is thin, except that it is already heavy on the top and light on the bottom, and the center of gravity is too high. In addition to the defects, when it is mounted on the camera, the center of gravity is even higher, such as figure 1 As shown, the height H1 of its center of gravity G1 is almost close to the position of the center plate 1, plus some actions of the photographer when operating the camera, such as dialing, pulling, and pressing, will be transmitted to the farthest and thinnest part. knots, resulting in tremors, affecting photography

[0003] Furthermore, in order to pursue the portability of the tripod, it is always attempted to shorten the tripod. Under the principle that the total extension height cannot be changed, the number of legs can only be increased and the length of the legs shortened, from the original three to four legs. Increase to five to six sections, due to the limitation of the most detailed bending resistance, it is no longer possible to consider the finer direction, only the outermost two sections can develop thicker, such as figure 1 As shown, in this way, the center plate 1 connecting and combining the three legs will become too large, and the defect of being heavy on the top and light on the bottom will become more serious
