technical field

The invention relates to a three-dimensional and two-dimensional switching device for a spherical cloud platform, which belongs to the field of camera equipment.

Background technique

The spherical head is widely used in outdoor film shooting due to its compact structure and quick operation. In most photography occasions, it is more convenient to use a three-dimensional spherical head. When the load is heavy and the center of gravity is high, the platform is easy to fall to the sides. At this time, it is necessary to purchase another pan-tilt. In this way, it is necessary to carry multiple pan-tilts when shooting outdoors, and it is very inconvenient to replace the pan-tilt frequently when shooting indoors. Especially in recent years, the new trend of digital SLR is to integrate the camera function, which requires the gimbal to be improved to adapt to the new development.

Detailed ways

Example 1:

Referring to Fig. 1, 2, the three-dimensional and two-dimensional switching device of the cloud platform of the present invention comprises the left and right gates 2, 3 that are arranged on the outside of the platform body 1 and match with the shape of the platform body 1, and the above-mentioned left and right gates 2, 3 are " U” shape, two dovetail guide rails 5 are fixedly connected by screws 4 on both sides of the pan/tilt body 1, and dovetail grooves 6 are provided on the inner sides of the left and right gates 2 and 3, and the left and right gates 2 and 3 can be horizontal along the dovetail guide rails 5 Sliding, 4 spring pins 7 are also fixed on the cloud platform body 1, and the left and right gates 2, 3 inboards are provided with grooves corresponding to the spring pins 7, and the spring pin 7 ends can slide horizontally in the above-mentioned grooves.

The course of work of embodiment 1 is:

Fig. 3 is the front view that the present invention is in three-dimensional state, left and right gate 2,3 are respectively positioned at the cloud platform body 1 both sides, and spring pin 7 ends are positioned at one end of left and right gate 2,3 inner side grooves, and now, left and right gate 2, 3. There are no restrictions on the ball handle 81. The gimbal can move in three dimensions. If you need to switch to the two-dimensional state, push the left and right gates 2 and 3 to the middle respectively, and the dovetail grooves 6 inside the left and right gates 2 and 3 are along the dovetail-shaped guide rail 5 slides to the middle, and the spring pin 7 slides relatively along the groove. When the left and right gates 2 and 3 are pushed to the middle (as shown in Figure 2), the four spring pins all pop out from the groove, limiting the outward direction of the left and right gates 2 and 3 At this time, the distance between the left and right gates 2 and 3 is the same as the diameter of the ball handle 81, and the left and right gates 2 and 3 limit the movement of the ball handle 81. The relative motion between the ball 8 and the cloud platform body 1 has only two dimensions of pitch and rotation. The platform is in a two-dimensional state and can perform two-dimensional movement. When it is necessary to return to the three-dimensional state, it is only necessary to press the spring pin 7 respectively to make the spring pin 7 enter the inner groove of the left and right gates 2 and 3, and the left and right gates 2 and 3 It only needs to be pushed to the two sides correspondingly, and the relative movement between the pan-tilt body 1 and the ball 8 increases the left-right swinging movement.

Example 2:

As shown in Figures 4, 5, and 6, this embodiment also includes left and right gates 2, 3 that are arranged on the outside of the pan-tilt body and match the shape of the pan-tilt body 1, and the devices that realize the horizontal sliding of the left and right gates 2, 3 are located The left and right sides of the main body 1 include bolts 9 connected with the left and right gates 2 and 3 respectively. The main body 1 of the pan/tilt is provided with an accommodation hole 10 correspondingly. In cooperation, the bolt 9 is connected with the knob 12 through the connection body 11 , and the connection body 11 is fixedly connected with the knob 12 through the screw 13 .

The course of work of embodiment 2 is:

Fig. 4 is the front view of embodiment 2 in a two-dimensional state, the left and right gates 2, 3 fix the ball handle 81, so that the ball handle 81 can only rotate relative to the pan-tilt body 1 and perform pitching motion along the grooves formed by the left and right gates 2, 3 , the ball table is in a two-dimensional state, turn the knob 12, the knob 12 drives the bolt 9 to rotate, the bolt 9 moves to both sides relative to the head body 1, and at the same time drives the left and right gates 2 and 3 to move to both sides. When it is in the state shown in Figure 5, the left and right gates 2.3 The ball handle 81 is no longer fixed, and the ball handle 81 can swing left and right within a certain range relative to the head body 1, and the ball table is in a three-dimensional state.
