Description

Technical Field

[0001] The utility model relates to the technical field of photographic equipment, in particular to a rotatably adjustable tripod ring structure. Background Art

[0002] Prior art, such as the Chinese utility model patent document with publication number CN211878278U, discloses a tilt-shift lens tripod ring bracket, comprising: a ring seat, a first frame ring, a second frame ring and a snap fastener, wherein the first frame ring is fixedly arranged on the ring seat, one end of the first frame ring is rotatably connected to one end of the second frame ring, the other end of the first frame ring is snapped to the other end of the second frame ring via the snap fastener, and a mating surface is fixedly provided on both sides of the first frame ring, and the mating surface is concave and convex.

[0003] Based on the above, in the prior art, the tripod ring bracket is an accessory that is fixedly connected to the lens and can be fixed on the tripod head. The technical problem with the existing tripod ring bracket is that after the lens is installed on the tripod ring, when the tripod ring is in a state of holding the lens, the camera and the lens cannot be rotated relative to the base of the tripod ring. As a result, during the photography process, when the camera needs to be rotated to switch between vertical and horizontal shooting, only the spherical head can be adjusted, but the adjustment of the spherical head will not be able to quickly switch between vertical and horizontal shooting. Due to the characteristics of the spherical head, the camera will be offset in the front, back, left and right directions. As a result, when adjusting the spherical head, it is necessary to observe the spirit level to ensure the level of the camera, which is too cumbersome and needs further improvement.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See also Figures 1-6 A rotatable and adjustable tripod ring structure includes a base 10, on which a connecting ring 20 fixedly connected to a lens is rotatably provided, and a locking assembly 30 is provided on the base 10 for restricting the connecting ring 20 from rotating relative to the base 10.

[0029] The rotatable connecting ring provided in this utility model allows the camera and lens to be rotated relative to the base, once the connecting ring and lens are fixedly connected, to switch between vertical and horizontal shooting angles. During rotational adjustment, the locking assembly is unlocked. After adjustment is complete, the locking assembly locks the connecting ring to prevent it from rotating freely and affecting normal shooting.

[0030] See also Figures 1 to 4The connecting ring 20 is provided with a rotating connecting portion 200, which is open on one side and has a limit portion 250 on the other side. A limit member 260 is detachably connected to the open side of the rotating connecting portion 200. The base 10 is provided with a first clamping element 110 and a second clamping element 120 spaced apart from each other. The front and rear walls of the rotating connecting portion 200 are provided with arcuate track grooves 240, and the first clamping element 110 and the second clamping element 120 are respectively movably inserted into the arcuate track grooves 240. Under the action of the first clamping element 110 and the second clamping element 120, the connecting ring 20 can be constrained, so that the connecting ring 20 can only rotate relative to the base 10, and cannot move forward, backward, or up and down relative to the base 10. It can only rotate to the left or right.

[0031] See also Figure 2 and Figure 4 The first clamping element 110 includes a first clamping seat 111 connected to the base 10. The first clamping seat 111 is provided with a plurality of first movable limiting members 112, which are movably inserted into the arc-shaped trajectory groove 240 on the front side. The second clamping element 120 includes a second clamping seat 121 connected to the base 10. The second clamping seat 121 is provided with a plurality of second movable limiting members 122, which are movably inserted into the arc-shaped trajectory groove 240 on the rear side. The arc-shaped trajectory groove 240 cooperates with the first movable limiting members 112 and the second movable limiting members to constrain the rotation of the connecting ring 20, so that the first movable limiting members 112 and the second movable limiting members 122 move within the arc-shaped trajectory groove 240 during rotation.

[0032] In the present invention, an opening is provided on one side of the rotating connection part 200. This setting is to enable the first movable limiting member 112 and the second movable limiting member 122 to enter into the arc trajectory groove 240 or detach from the arc trajectory groove 240 from the opening when the connecting ring 20 rotates, so as to realize the assembly or separation of the connecting ring 20 and the base 10.

[0033] In the present invention, the limiting portion 250 is used to prevent the first movable limiting member 112 and the second movable limiting member 122 from being separated from the end of the arc-shaped track groove 240 . The limiting portion 250 has a limiting function.

[0034] See also Figure 3 and Figure 4 The first clamping seat 111 is fixedly connected to the base 10, and the second clamping seat 121 is detachably connected to the base 10.

[0035] Furthermore, the second clamping seat 121 is fixedly mounted on the second clamping seat 121 by screws.

[0036] Furthermore, the first movable stopper 112 and the second movable stopper 122 are columnar structures and are respectively fixed to the first clamping seat 111 and the second clamping seat 121 by threaded connection.

[0037] See also Figure 5 and Figure 6 The base 10 has an installation cavity 100 with an upper opening, and the locking assembly 30 is arranged in the installation cavity 100. The locking assembly 30 moves up and down relative to the installation cavity 100 to achieve the locking by pushing the connecting ring 20 upward.

[0038] See also Figure 5 and Figure 6 The mounting cavity 100 is provided with a driving block 310 that can move laterally relative to the mounting cavity 100, and the mounting cavity 100 above the driving block 310 is provided with a driven block 320 that can move longitudinally relative to the mounting cavity 100, the upper surface of the driving block 310 is a first inclined surface, and the lower surface of the driven block 320 is a second inclined surface, and the first inclined surface is in contact with the second inclined surface; the mounting cavity 100 is provided with a first elastic element 340 and a second elastic element 350; a driving bolt 330 is threadedly connected to the base 10, one end of the driving bolt 330 extends into the mounting cavity 100, and the driving bolt 330 is used to push the driving block 310 to move in a direction away from the driving bolt 330, and the first elastic element 340 is used to push the driving block 310 to move in a direction close to the driving bolt 330; the second elastic element 350 is used to push the driven block 320 to move downward.

[0039] When the locking assembly is locking, the driving bolt 330 is rotated, which pushes the driving block 310 to move toward the direction close to the driving bolt 330. Under the action of the first inclined surface and the second inclined surface, it can drive the driven block 320 to move upward so that the driven block 320 is pressed against the outer wall surface of the connecting ring 20, thereby restricting the rotation of the connecting ring 20 and achieving locking.

[0040] See also Figures 3 to 6 The connecting ring 20 has a limiting groove 270 on its wall facing the mounting cavity 100, and the base 10 has a rotating roller 130 movably embedded in the limiting groove 270. When the connecting ring 20 rotates, the rotating roller 130 moves along the limiting groove 270, and the cooperation between the two can enhance the stability of the connecting ring 20 during the rotation process.

[0041] See also Figures 1 to 4The connecting ring 20 includes a connecting section 210 and a locking section 220. One end of the locking section 220 is connected to the connecting section 210. A connecting bolt 230 is rotatably connected to the other end of the locking section 220. The connecting bolt 230 is threadedly connected to the connecting section 210. The rotating connecting portion 200 is provided on the connecting section 210. By tightening or loosening the connecting bolt 230, the tightening state of the connecting section 210 and the locking section 220 can be changed, thereby fixing or loosening the lens.

[0042] In the present invention, the limiting member 260 is a screw.
