Torsion spring rotation gear and security tripod head

Abstract

The invention relates to a torsion spring rotational mechanism and a security cloud platform which applies the torsion spring rotational mechanism. The security cloud platform comprises a main bracket, a driven shaft which can rotate forwards or reversely, and a camera component; a torsion spring is nested on the external periphery of the driven shaft; the torsion spring is provided with a first end a second end which are arranged separately; a fixed limit part which limits the first end and the second end of the torsion spring simultaneously is fixed on the main bracket; a movable limit part is fixed on the driven shaft; the movable limit part compresses the first end compression torsion spring when the driven shaft rotates forwards; the movable limit part compresses the second end compression torsion spring when the driven shaft rotates reversely. The movable limit part respectively compresses the first end and the second end of the torsion spring when the rotary shaft (the driven shaft) rotates forwards and reversely, so as to enable the torsion spring to be in the compressed state; namely, the torsion spring moves in the maximum allowed elastic deformation range all the time so that the usable elastic transformation is great; the service life of the torsion spring is improved; the possibility on the fracture of the torsion spring is reduced.

Description

technical field [0001] The present invention relates to a rotating structure and a security cloud platform structure, more specifically, a torsion spring rotation mechanism and a security platform applying the structure. Background technique [0002] As an energy storage element, torsion spring is widely used in various industries such as electronics and machinery. In some rotating mechanisms, torsion springs are also used as energy storage reset elements. For example, in the security industry, torsion springs are applied to the pan / tilt to provide energy for the reset of the driven shaft. [0003] Such as figure 1 As shown, it is a structural schematic diagram of an existing security cloud platform, including a main bracket 901, a forward and reverse motor 902 is installed on the bottom of the main bracket 901, a driven shaft 903 is installed on the top of the main bracket 901, and the forward and reverse motor 902 drives the driven shaft 903 to rotate through the pulley ...

AI Technical Summary

Problems solved by technology

[0007] It can be seen that the existing torsion spring installation structure, especially in the pan / tilt of security equipment, always has the situation that the torsion spring is stretched and the service life is short, which is not conducive to the long-term use of the equipment
