Description

A ball head orientation device suitable for monopod

technical field

The utility model relates to a ball head orientation device for photographic equipment, in particular to a ball head orientation device suitable for monopods.

Background technique

When using photographic equipment to take pictures, in order to reduce the shaking of the photographic equipment during shooting and improve the quality of the video, a tripod that fixes the photographic equipment is usually used to assist the shooting, and in order to achieve all-round shooting of the photographic equipment, people generally choose Use tripods with 360-degree rotation/swing functions, most of which use ball head rotation/swing devices to achieve 360-degree rotation/swing of photographic equipment, and ball head rotation devices are generally used on the sphere Apply pressure in one direction to achieve locking, but the locking force in a single direction is often not strong enough, and the locking effect is not good.

In order to solve the above problems, Chinese patent document CN201373969Y discloses a ball head locking structure of a photography platform, which includes a ball head body, a ball head shell and a support seat, the support seat is located in the ball head shell, and the ball head body is located between the support seat and the support seat. Between the ball shells, the support seat can move in the axial direction of the ball shell under the action of the adjustment knob. Inside the ball body, a gasket is set on the top of the ball body. The inner surface of the gasket and the ball head The outer surface of the main body is suitable, and there is a groove on the outside. The two sides of the groove are inclined surfaces inclined outward. There is a ring of bumps inside the ball head shell, and the bumps are matched with the groove of the washer. ; In the ball head locking structure described in the above-mentioned patent documents, the adjustment knob is tightened, the support seat is subjected to upward pressure, and then pressure is applied to the ball head main body, and the ball head main body applies pressure to the washer at the same time, as the pressure of the support seat increases increase, the locking force of the ball head body will gradually increase. In the process of gradually increasing the locking force, the two slopes of the groove of the outer ring of the gasket expand and deform outwardly, increasing the force-bearing area between the ball head body and the washer, thereby The locking force of the main body of the ball head is increased. In the locking structure of the ball head, the upper and lower directions of the main body of the ball head are under pressure at the same time, and the locking effect is better.

The ball joint locking structure described in the above-mentioned patent documents mainly has the following disadvantages: in the ball joint locking structure, the ball joint main body is in contact with the washer and the support seat on an arc surface, and the ball joint main body In the rotating state or in the locked state, the lower end of the ball head is in contact with the support seat from beginning to end. In this way, during the rotation of the ball head body, the lower end of the ball head body will rub against the support seat. After a period of use, the friction between the two The contact arc surfaces will be worn, making the contact surfaces easy to become uneven and no longer smooth, which will cause the ball body and the support seat to not completely fit after the ball head locking structure is locked, and there will be gaps. The locking is not reliable, so that the main body of the ball head is easy to vibrate or tilt at a certain angle under the weight of the device connected to the upper end or when touched by external force, which will affect the photography/camera effect of the photographic equipment or cause photography/video The angle is not accurate and the reliability is poor.
