Abstract

This utility model provides a quick-adjusting horizontal locking device, tripod, and photography kit, including a hemispherical cup, a clamping base, a hemispherical pressure block, and a connecting post. The clamping base includes a base body and a clamping assembly. The base body has a first through groove along its radial cross-section and a second through groove along its transverse cross-section. The outer peripheral wall of the base body has clamping arms on both sides of the first through groove. The clamping assembly is connected to the two clamping arms and drives the two clamping arms to move closer together in the center. The connecting post connects the pressure block, the hemispherical cup, and the base body together, with a clearance fit between the convex and concave spherical peripheral walls, and the hemispherical pressure block is adjacent to the hemispherical cup. Then, the hemispherical cup rotates horizontally relative to the base body, and the clamping assembly drives the two clamping arms to move closer together in the center. The arrangement of the first and second through grooves enables the base body to deform and clamp the hemispherical cup, thus achieving quick adjustment and quick clamping and fixing.

Description

Technical Field

[0001] This utility model relates to the field of photographic auxiliary equipment technology, and in particular to a quick-adjusting horizontal adjustment locking device, a tripod, and a photographic kit. Background Technology

[0002] Ordinary photography tripods do not have a leveling function on uneven ground when the center column height adjustment bracket is mounted. The center column height adjustment bracket can only be adjusted up and down, which limits macro photography and shooting from special angles. This restricts operation, makes framing difficult, and results in uneven images. Even if auxiliary equipment such as a 3D head is used to help the photography equipment find a level position, it is still inconvenient to operate, causing you to miss the best shooting time and significantly increasing the cost of photography. Utility Model Content

The connecting post passes through the hemispherical pressing block and the hemispherical bowl and is connected to the seat. The end of the connecting post is adjacent to the hemispherical pressing block, and the hemispherical pressing block is adjacent to the hemispherical bowl.

[0007] A further solution is that the clamping assembly includes a knob and a screw. The screw is threaded into two clamping arms respectively, and the knob is connected to the end of the screw. The knob drives the screw to rotate, which in turn drives the two clamping arms to move closer together in the center.

[0008] A further proposed solution is to place the second through slot below the screw.

[0009] A further option is that the horizontal adjustment locking device includes a height adjustment column, which extends vertically and is located below the base, and the height adjustment column is fixedly connected to the base.

[0010] A further proposed solution is to have a first fixing hole in the vertical direction on the height adjustment column, a first positioning hole in the base body at the position corresponding to the first fixing hole, and a connecting column passing through the first positioning hole and being fixedly connected to the first fixing hole.

[0011] A further solution is to have multiple second fixing holes along the vertical direction on the height adjustment column, with the multiple second fixing holes located on the outer periphery of the first fixing hole. The base body has a second positioning hole at the position corresponding to the second fixing hole, and a connecting screw passes through a second positioning hole and is fixedly connected to a second fixing hole.

[0013] A further proposed solution is to make the curvature of the second through groove less than or equal to π.

[0014] To achieve the second objective of this utility model, this utility model provides a tripod, including leg supports and a horizontal adjustment and locking device as described above, wherein the horizontal adjustment and locking device is disposed at the upper end of the leg supports.

[0015] To achieve the third objective of this utility model, this utility model provides a photography kit, including a three-dimensional gimbal and a horizontal adjustment and locking device as described above, wherein the three-dimensional gimbal is connected to a hemispherical bowl.
