Low-gravity-center spherical cloud platform locking structure

Abstract

The invention provides a low-gravity-center spherical cloud platform locking structure. The locking structure comprises a barrel body, a ball body, a locking seat, a conical gear rotating seat, a bearing and a locking driving rod, and the ball body, the locking seat, the conical gear rotating seat and the bearing are all arranged in a locking cavity of the barrel body; the bearing is arranged at the bottom of the locking cavity; the conical gear rotating seat is rotatably mounted on the bearing, the conical outer surface of the conical gear rotating seat is provided with teeth, and the side wall of an inner ring is provided with an inner thread; a rotary knob is arranged at one end of the locking driving rod, the other end of the locking driving rod passes through the barrel body and extends into the locking cavity, the end of the locking driving rod is provided with a bevel gear, and the bevel gear is connected with the teeth of the conical gear rotating seat in an engaged manner; and the circumferential side surface of the locking seat is provided with an outer thread, the locking seat is arranged in the inner circular ring of the conical gear rotating seat, the outer thread is connected with the inner thread in a matched and engaged manner, and the locking seat moves up and down under the action of the conical gear rotating seat. The locking structure is stable and reliable in locking effect, ingenious and compact in structure, low in axial height and production cost, small in size and convenient to use and carry.

Description

【Technical field】 [0001] The invention belongs to the technical field of cloud platforms, and in particular relates to a locking structure of a spherical platform with a low center of gravity. 【Background technique】 [0002] At present, the existing photographic tripods on the market are equipped with spherical heads to adjust the angle of the quick mount; however, the existing spherical heads are directly supported and locked on the ball seat by the locking rod on the outside of the ball seat The universal ball inside is used to achieve locking, the locking effect is extremely poor, extremely unstable, and it is easy to cause damage to the surface of the universal ball, affecting normal work, and the axial height is relatively high, not only high cost, but also relatively bulky, occupying a lot of space , It is inconvenient to use and carry. 【Content of invention】 [0003] In order to solve the above-mentioned technical problems existing in the prior art, the present inv...
