Description

Technical Field

[0001] This utility model relates to photographic support technology, and more particularly to a locking structure for a photographic support. Background Technology

[0002] A camera tripod is a support device used for camera or camcorder pan / tilt heads. It uses a fixing mechanism to secure the pan / tilt head to the tripod, thus supporting the camera or camcorder mounted on it. Existing fixing mechanisms mostly use bolts for tightening. This type of tightening lacks elastic cushioning and can damage the surface of the camera or camcorder, reducing its aesthetic appeal. Furthermore, loose bolts can lead to unstable fixing, causing the camera or camcorder to shift and affecting shooting quality. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model proposes a locking structure for a photography bracket.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A locking structure for a camera bracket, characterized in that it comprises:

[0006] A base, on which a telescopic rod is provided.

[0007] A fixing seat is installed on the telescopic rod. The fixing seat has a hollowed-out middle chamber to form a fixing chamber. A retaining cylinder is provided in the fixing chamber. The retaining cylinder has multiple toothed grooves. A through hole is formed in the middle of the retaining cylinder. A rod is provided in the through hole. A disc is provided at the upper end of the rod and a rotating body is provided at the lower end. The disc is placed on the retaining cylinder. A rotationally symmetrical elastic arm is provided on the disc. The elastic arm cooperates with the toothed grooves to limit the movement. A spring is provided on the rod. One end of the spring contacts the outer wall of the fixing seat and the other end contacts the rotating body.

[0008] In the locking structure of this photographic bracket, the spring is in its natural state.

[0009] In the locking structure of this photographic bracket, the surface of the rotating body is provided with anti-slip texture.

[0010] In the locking structure of this photographic bracket, a compression area is formed between the elastic arm and the disc body.

[0011] In the locking structure of this photographic bracket of the present invention, the elastic arm is provided with teeth that cooperate with the tooth groove.

[0012] In the locking structure of this photographic bracket, the retaining cylinder is provided with a helical surface arranged in a rotational symmetry, and the toothed groove is placed on the helical surface.

[0013] In the locking structure of this photographic bracket, the two ends of the spiral surface are respectively provided with blocking bodies. One end of the blocking body is provided with a guide slope, and the other end is provided with a blocking surface. The blocking surface is located at the highest point of the spiral surface and the blocking surface is located at the lowest point of the spiral surface.

[0014] The locking structure of this photographic bracket has the following advantages: The locking structure uses elastic locking, which provides cushioning protection for the photographic equipment, preventing damage to its appearance and effectively protecting it. Furthermore, the unidirectional rotation structure makes locking and unlocking more convenient and simple to operate. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1 to 4 As shown, the locking structure of this photographic bracket includes a base 1 and a fixing seat 2. The base 1 is provided with a telescopic rod 3, and the fixing seat 2 is disposed on the telescopic rod 3.

[0021] The center of the mounting base 2 is hollowed out to form a mounting chamber 4, which is used to place the photographic equipment. By rotating the rotating body 5, the elastic arm 7 on the disc 6 moves continuously on the spiral surface 8, moving from a lower position to a higher position, thereby compressing the spring 9. This pushes the disc 6 to elastically lock the photographic equipment inside the mounting chamber 4.

[0022] A retaining cylinder 10 is provided inside the fixed chamber 4. The retaining cylinder 10 has multiple toothed grooves 11, and a through hole 12 is formed in the middle of the retaining cylinder 10. A rod 13 is provided inside the through hole 12. A disc 6 is provided at the upper end of the rod 13, and a rotating body 5 is provided at the lower end. The surface of the rotating body 5 is provided with anti-slip textures 14. The disc 6 is placed on the retaining cylinder 10. The disc 6 has a rotationally symmetrical elastic arm 7, and a compression area 15 is formed between the elastic arm 7 and the disc 6. The elastic arm 7 cooperates with the toothed grooves 11 for limiting movement. The elastic arm 7 has teeth 16 that cooperate with the toothed grooves 11. A spring 9 is provided on the rod 13. One end of the spring 9 contacts the outer wall of the fixed seat 2, and the other end contacts the rotating body 5. The spring 9 is in a natural state.

[0023] The retaining cylinder 10 has a rotationally symmetrically arranged helical surface 8, and the toothed groove 11 is placed on the helical surface 8. The helical surface 8 has a high point and a low point, and there is a distance difference between them. When the tooth 16 moves from the low point to the high point of the helical surface 8, the disc body 6 can be moved, thereby locking the photographic equipment.

[0024] The spiral surface 8 is provided with a blocking body 17 at both ends. One end of the blocking body 17 is provided with a guide slope 18, and the other end is provided with a blocking surface 19. The blocking surface 19 is located at the highest point of the spiral surface 8 and the blocking surface 19 is located at the lowest point of the spiral surface 8.

[0025] In use, simply rotate the rotating body 5 in one direction, as it will be blocked by the blocking plate 17 and cannot rotate in the opposite direction. During rotation, keep the teeth 16 rotating from the lower to the higher part of the spiral surface 8. This ensures that at each certain angle of rotation, the teeth 16 reach the corresponding limit in the tooth groove 11. Furthermore, the tooth groove 11 is unidirectional, with an inclined surface facing the higher part of the spiral surface 8 and a vertical blocking surface 19 facing the lower part, preventing the disc body 6 from driving the elastic arm 7 to rotate in the opposite direction.

[0026] Because the elastic arm 7 has a certain elasticity, the locking of the camera equipment is an elastic lock. When it is necessary to unlock, simply continue to rotate the rotating body 5 so that the teeth 16 pass over the blocking body 17 under the guidance of the guide slope 18 to unlock and remove the camera equipment.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
