Description

Technical Field

[0001] This utility model relates to the field of photographic gimbal technology, specifically to a gimbal locking device with a roller needle structure and a photographic kit. Background Technology

[0002] Gimbals are the most commonly used components in cameras. Traditional ball heads, due to limitations in manufacturing technology, have relatively simple and direct locking structures. Most structures rely on a knob system that directly presses the ball through the base for locking, resulting in a rather stiff feel. In recent years, with the widespread use of CNC machine tools and advancements in processing technology, the manufacturing quality of gimbals has significantly improved, and various locking methods for the gimbal ball have emerged. This invention addresses the issue from the perspectives of gimbal control precision and improving the feel of the gimbal knob, providing a new solution for high-precision control of the gimbal ball's locking mechanism. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a gimbal locking device and a photography kit with a roller needle structure. This locking device can precisely control the locking of the gimbal ball and eliminate torque loss during the locking operation, so as to solve the technical problems described in the background art.

[0004] This utility model is achieved through the following technical solution:

[0005] A gimbal locking device with a needle roller structure includes a vertically arranged pusher A and a pusher B. A groove is formed on the side of the pusher B away from the pusher A, and a needle roller is installed in the groove. The diameter of the needle roller is greater than the depth of the groove.

[0006] The opposing surfaces of the two pushers are respectively provided with inclined plane structures with the same slope. When the pusher B, which is away from the gimbal sphere, is subjected to an external force and moves horizontally relative to the pusher A, the pusher B can use the inclined plane structure to push the pusher A to move vertically and lock the gimbal sphere.

[0007] Furthermore, a lead screw hole is provided on the side of the pusher B, and a lead screw is threaded into the lead screw hole. A knob is fixedly connected to the end of the lead screw away from the pusher B.

[0008] Furthermore, the pusher A protrudes to one side of the pusher B to form two spaced-apart protrusions, and the inclined structure on the protrusions fits into each other with the inclined structure on the pusher B.

[0009] Furthermore, the protrusion and the inclined structure of the pusher B are respectively provided with receiving holes, and an elastic mechanism is installed in the receiving holes to ensure that there is a damping force between the pusher A and the gimbal ball when the gimbal ball is unlocked.

[0010] Furthermore, the elastic mechanism includes a sleeve fitted into the receiving hole, a spring installed in the sleeve, and a ball installed at the other end of the spring.

[0011] A photography kit includes a multi-functional gimbal, the multi-functional gimbal including a gimbal base, and a chassis is fixedly connected to the bottom opening of the gimbal base;

[0012] A ball sleeve is inserted into the top opening of the gimbal base, and a ball is rotatably installed in the ball sleeve. A gimbal locking device with a roller structure as described above is installed between the ball and the chassis.

[0013] Furthermore, a sliding groove is provided on the inner wall of the gimbal base, and a guide block is integrally formed on the outer side of the pusher A for sliding engagement with the sliding groove to restrict the circumferential rotation of the pusher A.

[0014] Furthermore, a threaded hole is provided on the side of the gimbal base, and a fixing sleeve is threaded into the threaded hole, the fixing sleeve being sleeved on the lead screw;

[0015] The lead screw includes a threaded portion and a rod portion integrally formed with the threaded portion. The rod portion is inserted into the fixed sleeve, and a stop ring is installed on the rod portion to cooperate with the fixed sleeve to restrict the horizontal movement of the lead screw.

[0016] A photography kit further includes a photography and video leveling gimbal, the photography and video leveling gimbal employing a gimbal locking device with a roller structure as described above.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Compared with the traditional gimbal ball locking structure, this utility model utilizes the precision adjustment feature of the lead screw. The pusher B is precisely displaced along the axial direction of the lead screw under the rotation control of the lead screw, thereby precisely controlling the clamping force and damping feel of the ball. At the same time, the lead screw has a positioning function for the movement of the pusher B, and also ensures that the damping force of the feel is constant when the ball rotates.

[0019] 2. This utility model utilizes the principle of inclined plane to further amplify the lateral torque provided by the lead screw (amplify the torque in the vertical direction), making the operation of locking the ball with the knob easier and providing a better feel. At the same time, the pusher B, driven by the lead screw, also achieves precise adjustment of the locking torque of the ball.

[0020] 3. This utility model utilizes the special structure of the sliding needle roller to eliminate and reduce the frictional resistance generated during torque transmission, greatly reducing torque loss during operation and providing photographers with a light and smooth feel when operating the gimbal.

[0034] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0035] In the description of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] Please see Figures 1 to 4 This utility model provides a technical solution: a gimbal locking device with a roller needle structure, comprising a vertically arranged pusher A1 and a pusher B2. The pusher is preferably disc-shaped, but can also be rectangular or other shapes as needed. A lead screw hole 6 is provided on the side of the pusher B2, and a lead screw 7 is threaded into the lead screw hole 6. A knob 8 is fixedly connected to the end of the lead screw 7 away from the pusher B2. By turning the knob 8, the lead screw 7 is rotated, thereby precisely adjusting the movement distance of the pusher B2.

[0037] Please see Figure 1 The bottom of the pusher B2 has a groove 3, in which a needle roller 4 is installed. The needle roller 4 is preferably cylindrical, but can also be spherical. The rolling direction of the needle roller 4 is parallel to the center line of the lead screw 7. The diameter of the needle roller 4 is greater than the depth of the groove 3. The needle roller 4 extends out of the groove 3. The needle roller 4 can convert the sliding friction generated during the movement of the pusher B2 into rolling friction and reduce the contact area between the pusher B2 and other objects during the movement. This reduces the friction generated during the movement of the pusher B2, making the movement of the pusher B2 more light and smooth.

[0038] Please see Figure 1 and Figure 4 The pusher A1 protrudes towards one side of the pusher B2 to form two spaced and opposite protrusions 9. The opposite surfaces of the protrusions 9 and the pusher B2 are respectively provided with inclined surface structures 5 with the same slope. The protrusions 9 can reduce the contact area between the pusher A1 and the pusher B2, thereby reducing the friction between the pusher B2 and the pusher A1 when the pusher B2 moves and pushes the pusher A1. When the pusher B2 moves horizontally relative to the pusher A1 under the cooperation of the knob 8 and the lead screw 7, the pusher B2 can push the pusher A1 vertically by means of the inclined surface structure 5, thereby locking the gimbal ball.

[0039] When the pusher B2 moves away from the inclined surface of the pusher A1 under the drive of the lead screw 7, there is no pressure between the pusher A1 and the ball, and the gimbal ball will be unlocked.

[0040] Please see Figure 3 The protrusion 9 and the inclined structure 5 of the pusher B2 are respectively provided with receiving holes 10. An elastic mechanism 11 is installed in the receiving hole 10. The elastic mechanism 11 includes a sleeve 111 embedded in the receiving hole 10. A spring 112 is installed in the sleeve 111. A ball bearing 113 is installed at the other end of the spring 112. In the natural state, the ball bearing 113 abuts against the opening of the sleeve 111 under the action of the spring 112. The ball bearing 113 is in a state of being half-extended from the sleeve 111. When the gimbal ball is unlocked, the spring 112 and the ball bearing 113 push the pusher A1 to move and abut against the gimbal ball, so that a certain damping force is maintained between the gimbal ball and the pusher A1, so as to prevent the gimbal ball from being too loose and wobbling when unlocking.

[0041] Please see Figure 5 and Figure 6 A photography kit includes a multi-functional gimbal 12, the multi-functional gimbal 12 including a gimbal base 121, a base 122 fixedly connected to the bottom opening of the gimbal base 121, and a pusher B2 slidably mounted on the base 122.

[0042] A ball sleeve 123 is inserted into the top opening of the gimbal base 121, and a ball 124 is rotatably installed in the ball sleeve 123. The ball 124 has a connecting post with a threaded interface for connecting to a clamp or tripod. A gimbal locking device with a needle roller structure as described above is installed between the ball 124 and the chassis 122.

[0043] Please see Figure 3 and Figure 7 The inner wall of the gimbal base 121 is provided with a sliding groove 125. The outer side of the pusher A1 is fixedly connected with a guide block 126 for sliding cooperation with the sliding groove 125, thereby restricting the circumferential rotation of the pusher A1, so that the pusher A1 only moves up and down and does not produce horizontal and rotational movements, thereby ensuring that the upper and lower inclined structures 5 are always relative.

[0044] Please see Figure 6 The gimbal base 121 has a threaded hole 127 on its side, and a fixing sleeve 128 is threaded into the threaded hole 127. The fixing sleeve 128 is sleeved on the lead screw 7.

[0045] The lead screw 7 includes a threaded portion 71 and a rod portion 72 integrally formed with the threaded portion 71. The rod portion 72 is inserted into the fixing sleeve 128, and the inner wall of the fixing sleeve 128 is in smooth contact with the outer surface of the rod portion 72. A stop ring 129 is installed on the rod portion 72. The stop ring 129 is located in front of the fixing sleeve 128 and is used to cooperate with the fixing sleeve 128 to restrict the horizontal movement of the lead screw 7, prevent the lead screw 7 from moving outward when it is screwed, and ensure that the lead screw 7 effectively drives the pusher B2 to move horizontally.

[0046] Please see Figure 8 and Figure 9 A photography kit, further comprising a photography and video leveling gimbal 13, wherein the photography and video leveling gimbal 13 is equipped with a gimbal locking device of the roller structure as described above, and the roller structure gimbal locking device is installed in the photography and video leveling gimbal 13 in a similar manner to the multi-functional gimbal 12.

[0047] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
