Description

Versatile ball head for industrial and tripods {A very useful ball head for industry and tripods supports}

The present invention can easily adjust the horizontal, vertical angle, direction and rotation of the device when using a photographic device, telescope, video recording equipment, surveying equipment, lighting equipment and other industrial equipment

The present invention relates to a versatile ball head for industrial and tripods, which can be used as a control.

Conventional control device for adjusting the angle, direction, etc. of the device has been largely used in the ball type, the lap fixing method, etc., but there were many problems in the fastening force (fastening force) and convenience.

In particular, the ball head for photo equipment is a device that can be mounted on a tripod to fix cameras, videos, telescopes, etc., and can be rotated and fixed at an arbitrary angle, and is known as a new technology requiring ultra-precision, robustness, and safety. In addition, as the users demand precision and convenience, all of them depend on imported goods due to domestic technology deterioration.

In other words, the ball head needs to maintain heavy equipment at any angle without vibration, and requires great support and precision, and it is well suited to expensive photo equipment, video cameras, lighting equipment, etc., while satisfying simplicity and convenience of operation. Aesthetically beautiful appearance is also required.

These ball heads are composed of a eccentric cam fixed to a small ball on one axis, or a mechanism and a simple cam or cone for fastening or bolting a bolt to a large shaft, and thus a large fastening force due to friction between small balls and lubricants. There is a problem in fixing the ball in the desired position due to the disadvantage that the ball is not fixed to the gravity axis of the ball head because it has a limit on the durability and the eccentric cam or draining.

In addition, the ball-type ball head has a limitation in precision or durability because its body is manufactured by a casting method (Casting, DieCasting) or the metal and the metal are to be directly rubbed to apply lubricating oil, and the ball is simply eccentric in operation. It is hard to get big force by using the user's hand only to fix the cam or draining rod by screwing the screw rod by force rotation. It can be used for cameras or video cameras, where the durability is not sufficient because the wear of the friction part is severe while repeated locking and unlocking due to forced fit due to the forced friction of drainage, and the wear and tear of the friction part is severe. If the locking part is locked, it will be tightened. If it is loosened, it will be completely loosened. Will also result in damage to the unit flat when fixed direction, that is, do not hold the device, nor time consuming and inconvenient to catch the tool by hand.

In addition, the Lava type separates three or more Lava, such as the angle adjusting Lava, the rotation adjusting Lava, the horizontal adjusting Lava, and the cumbersome and heavy weight to be adjusted, causing inconvenience to carry and install. It has the disadvantage of not fine-tuning.

The present invention has been made to improve the above-mentioned disadvantages, in particular, the present invention by using a durallumin material in the ball head to increase the high precision and durability while increasing the lightness and robustness and extremely low the center point of the ball to increase the torque It can be widely used in various industrial devices because it is convenient to use because it can adjust horizontal, vertical and angle as well as small or large weight devices by adjusting the tightening force with a small clamping force and a single operation. It is aimed at providing a ball head that enables easy and precise adjustment of the fine tension adjusting device, safety device and angle rotating plate with one touch. The method consists of four cam structures that maintain their center point as the shaft is configured in an unfixed state. It is an object of the present invention to provide a miniaturized ball head for boosting power.
