Description

Technical Field

[0001] This utility model belongs to the field of gimbal structure technology, specifically relating to a safety block position adjustment mechanism for a photographic gimbal. Background Technology

[0002] A camera tripod is a platform used to mount external equipment such as cameras and camcorders. A typical camera tripod has mounting slots that extend through both ends, and quick-release plates for mounting external equipment such as cameras and camcorders can be detached and installed inside the mounting slots.

[0003] In order to capture scenery from all directions, cameras or camcorders often need to be tilted. At this time, the quick-release plate is prone to falling off the mounting slot, causing the camera or camcorder to be damaged. Therefore, the camera tripod needs to be equipped with a safety block, and the corresponding position on the quick-release plate is equipped with a positioning groove that matches the safety block, so as to prevent the quick-release plate from falling off the camera tripod.

[0004] In the prior art, the positions of the positioning grooves on different quick-release plates are not the same. Correspondingly, the position of the safety block on the Yuntao also needs to be adjustable to facilitate switching between two positions and adapt to different quick-release plates. Based on this, this application has conducted further research on the position adjustment mechanism of the safety block. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a safety block position adjustment mechanism for a camera tripod, which has a compact structure and is easy to adjust.

[0006] The present invention is solved by the following technical solution.

[0007] A safety block position adjustment mechanism for a camera tripod includes a tripod body with a sliding groove on the tripod body. A safety block extends out of the sliding groove. The position of the safety block is adjusted by an adjustment mechanism on the tripod body. The adjustment mechanism includes a toggle block located on the back of the tripod body, which is rotatably mounted on a positioning post. The toggle block has a second sliding groove, and a portion of the safety block slides within the second sliding groove. When the toggle block rotates, the safety block moves simultaneously within the second sliding groove, thus adjusting the position of the safety block.

[0008] The safety block position adjustment mechanism in this application allows the actuating block to rotate around the positioning column. During rotation, the safety block moves from one side of the slide groove to the other side through the limiting action of the slide groove and the second slide groove, thereby adjusting the position of the safety block. The operation is convenient.

[0009] In a preferred embodiment, the slide groove is a strip-shaped hole, and the second slide groove is also a strip-shaped hole. Specifically, the strip-shaped hole is a straight, elongated strip-shaped hole with rounded ends. The slide groove and the second slide groove are staggered in the length direction, so that when the actuating block rotates, the safety block moves from one end of the second slide groove to the other end, and at the same time moves from one end of the slide groove to the other end, ensuring that the actuating block can move smoothly in the slide groove during the rotation of the actuating block without getting stuck.

[0010] In a preferred embodiment, the actuating block is provided with a lever for easy manual operation.

[0011] In a preferred embodiment, a positioning bead is provided on the end face of the lever facing the gimbal body, and at least two corresponding positioning holes are provided on one side of the gimbal body, so that the positioning bead can enter the positioning hole to realize positioning feedback.

[0012] In a preferred embodiment, one side of the lever is provided with a mounting hole, and a spring, specifically a compression spring, is provided in the mounting hole to provide elastic force. The positioning bead is disposed on the opening of the mounting hole, and the elastic force allows the positioning bead to provide a certain locking force after entering the positioning hole.

[0013] In a preferred embodiment, the lever is located on the side of the actuating block away from the positioning post, making operation easier.

[0014] In a preferred embodiment, the actuating block is provided with a rotating hole fitted onto the positioning post.

[0015] In a preferred embodiment, the positioning post has a hollow structure and is equipped with anti-loosening bolts, so that the actuating block will not come out after assembly.

[0016] In a preferred embodiment, the safety block has a boss on its outer periphery, which is limited in the groove. For example, the groove has a stepped portion, and the boss is limited on the stepped portion, thus playing an axial limiting function.

[0017] In a preferred embodiment, the safety block is slidably assembled in the second groove by bolts to prevent it from coming out, resulting in a compact overall assembly structure.

[0018] Compared with the prior art, the present invention has the following advantages: it provides a safety block position adjustment mechanism for a camera tripod, which is compact in structure and easy to adjust. Attached Figure Description
