Description

Technical Field

[0001] This utility model relates to the field of gimbal technology, specifically to a gimbal for photography. Background Technology

[0002] In the photography and videography industry, tripods are frequently used, and the tripod head is selected differently depending on the purpose and application scenario. For example, in still photography scenarios, a photography tripod head is generally used, among which the ball head is the most widely used type of photography tripod head.

[0003] Existing ball heads typically have a large locking knob on the side. When a fixed angle is needed, rotating the locking knob causes internal components (such as pressure plates and wedges) to apply pressure to the ball. Due to the increased friction between the ball and the ball head housing, the ball can no longer rotate freely, thus fixing the camera or other equipment at the current angle.

[0004] However, because the locking knob protrudes outward from one side of the spherical gimbal, it is prone to friction and collision with external objects when being picked up or placed. The protruding locking knob is easily scratched and damaged. At the same time, the locking knob is relatively large, which makes it inconvenient to carry and store, and cannot meet the needs of use. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a photography gimbal that solves the problem of the locking knob protruding outward in traditional ball head. The locking knob is hidden, which makes it less likely to rub against or collide with external objects. It is also small in size, easy to carry and store, and meets the needs of use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A camera tripod includes a fixed platform and an angle adjustment assembly. The angle adjustment assembly is located at the lower end of the fixed platform and includes a universal ball, a limiting sleeve, a base, and a locking knob. The universal ball is located on the base, the limiting sleeve is fitted over the outside of the universal ball, and the side wall of the upper end of the limiting sleeve is bent inward and extends towards the middle of the limiting sleeve. The base is located on the locking knob, and the locking knob is detachably connected to the limiting sleeve and can move up and down along the limiting sleeve.

[0008] Furthermore, the lower end of the limiting sleeve is provided with an external thread, and the locking knob is provided with an internal thread. Through the cooperation of the internal and external threads, the locking knob can drive the universal ball on the base to move up and down.

[0009] Furthermore, the locking knob has a stepped surface in the middle, and the base is mounted on the stepped surface.

[0010] Furthermore, the limiting sleeve is provided with at least two limiting blocks. The limiting blocks extend from the inner sidewall of the limiting sleeve towards the center and are arc-shaped, adapting to the spherical surface of the universal ball. The base is provided with a limiting groove that adapts to the limiting blocks. When the base moves upward, the limiting blocks are inserted into the limiting grooves.

[0011] Furthermore, the upper end of the omnidirectional ball is equipped with a quarter screw, which extends upward through the fixed platform.

[0012] Furthermore, the lower end of the base is provided with a connecting seat, the upper end of the connecting seat is provided with an annular groove and a through hole, the lower end of the locking knob is provided with an annular plate that matches the annular groove, the annular plate is inserted into the annular groove, the bottom of the limiting block is provided with a screw hole corresponding to the position of the through hole, and the connecting seat and the limiting sleeve are detachably connected by screwing through the through hole into the screw hole.

[0013] Furthermore, the bottom of the connector has a quarter-expansion hole.

[0014] Furthermore, one side of the connector is provided with an auxiliary fixing hole that communicates with the quarter expansion hole.

[0015] The beneficial effects of this utility model are as follows: The angle adjustment component is located at the lower end of the fixed platform. The angle adjustment component includes a universal ball, a limiting sleeve, a base, and a locking knob. The universal ball is located on the base, and the limiting sleeve is fitted over the outside of the universal ball. The side wall of the upper end of the limiting sleeve is bent inward and extends towards the middle of the limiting sleeve to limit the position of the universal ball and prevent it from falling out of the limiting sleeve. At the same time, it limits the upward movement of the universal ball. The base is located on the locking knob, and the locking knob is detachably connected to the limiting sleeve and can move up and down along the limiting sleeve. When the locking knob moves the base... When the omnidirectional ball on the base moves upward, the upper end of the omnidirectional ball abuts against the curved part of the upper side wall of the limiting sleeve, and the lower end of the omnidirectional ball abuts against the base. The upper and lower ends of the omnidirectional ball are restricted at the same time. The abutment of the upper and lower ends generates sufficient friction and constraint force, making it difficult for the omnidirectional ball to rotate freely, thus achieving the locking effect. The locking knob is set at the lower end of the fixed platform, which solves the disadvantage of the traditional ball head locking knob protruding outward. The hidden design of the locking knob makes it less likely to rub against and collide with external objects. It is also small in size, easy to carry and store, and meets the needs of use.

Detailed Implementation

[0020] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments:

[0021] This embodiment: as follows Figure 1-3 As shown, a photographic gimbal includes a fixed platform 10 and an angle adjustment assembly 20. The angle adjustment assembly 20 is located at the lower end of the fixed platform 10 and includes a universal ball 21, a limiting sleeve 22, a base 23, and a locking knob 24. The universal ball 21 is mounted on the base 23, and the limiting sleeve 22 is fitted over the universal ball 21. The upper sidewall of the limiting sleeve 22 is bent inward and extends towards the middle of the limiting sleeve 22 to limit the position of the universal ball 21, preventing it from falling out of the limiting sleeve 22 and limiting the upward movement of the universal ball 21. The base 23 is mounted on the locking knob 24, and the middle of the locking knob 24 has a stepped surface 242. The base 23 is mounted on the stepped surface 242. The locking knob 24 and the limiting sleeve 22 are detachable. The lower end of the limiting sleeve 22 is provided with an external thread 221, and the locking knob 24 is provided with an internal thread 241. Through the cooperation of the internal thread 241 and the external thread 221, the locking knob 24 can drive the universal ball 21 on the base 23 to move up and down. When the locking knob 24 drives the universal ball 21 on the base 23 to move upward, the upper end of the universal ball 21 abuts against the curved part of the upper side wall of the limiting sleeve 22, and the lower end of the universal ball 21 abuts against the base 23. The upper and lower ends of the universal ball 21 are restricted at the same time. The abutment of the upper and lower ends generates sufficient friction and constraint force, making it difficult for the universal ball 21 to rotate freely, thereby achieving the locking effect. Setting the locking knob 24 at the lower end of the fixed platform 10 solves the disadvantage of the traditional ball head locking knob 24 protruding outward.

[0022] The limiting sleeve 22 is provided with three limiting blocks 222. The limiting blocks 222 extend from the inner side wall of the limiting sleeve 22 towards the center and are arc-shaped to fit the spherical surface of the universal ball 21. The base 23 is provided with a limiting groove 231 that fits the limiting blocks 222. When the base 23 moves upward, the limiting blocks 222 are inserted into the limiting groove 231. The design of the limiting blocks 222 and the limiting groove 231 serves to guide and limit, making it easier for the base 23 to move the universal ball 21 upward more quickly. At the same time, it prevents the base 23 from shaking or shifting during use.

[0023] The upper end of the omnidirectional ball 21 is provided with a quarter screw 211. The quarter screw 211 extends upward through the fixed platform 10 and is used to extend the connection of devices such as mobile phone clips and cameras.

[0024] The lower end of the base 23 is provided with a connecting seat 30. The upper end surface of the connecting seat 30 is provided with an annular groove 31 and a through hole 32. The lower end of the locking knob 24 is provided with an annular plate 243 that is adapted to the annular groove 31. The annular plate 243 is inserted into the annular groove 31. The bottom of the limiting block 222 is provided with a screw hole 223 corresponding to the position of the through hole 32. By screwing the screw through the through hole 32 into the screw hole 223, the connecting seat 30 and the limiting sleeve 22 can be detachably connected. The bottom of the connecting seat 30 is provided with a quarter expansion hole 33, which is a quarter screw hole 223, used to fix this product on equipment with a quarter screw, such as a bracket, tripod, etc. The side of the connecting seat 30 is provided with an auxiliary fixing hole 34 that communicates with the quarter expansion hole 33. The auxiliary fixing hole 34 is a wrench hole, used to assist in locking on the quarter screw.

[0025] This product solves the problem of the traditional ball head's locking knob 24 protruding outwards. The locking knob 24 has a hidden design, which makes it less likely to rub against or collide with external objects. It is also small in size, easy to carry and store, and meets the needs of users.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
