Technical Field

[0001] This utility model relates to the field of shooting auxiliary device technology, and in particular to a rotating mechanism, a fixing device and a bracket. Background Technology

[0002] Currently, common camera mounts primarily secure mobile phones using fixing devices. These devices typically consist of a base and a rotating base: the rotating base is rotatably connected to the back of the base. To lock the base in place after angle adjustment, existing technology generally adds a positioning plunger to the back of the base. This positioning plunger has a built-in spring and a ball head at its front end. During rotation adjustment, when the ball head is subjected to external force (such as contact with the surface of the rotating base), it retracts into the plunger body; when the external force is removed (the ball head reaches the positioning groove position of the rotating base), the spring pushes the ball head out, causing it to engage in the positioning groove, thereby locking the rotating base at a specific angle.

[0003] However, the above structure has significant shortcomings: achieving the rotational locking function requires an additional positioning plunger assembly. This not only increases the number of parts, making installation steps cumbersome and assembly inconvenient, but also increases the manufacturing cost of the fixing device. Utility Model Content

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] This utility model embodiment provides a rotating mechanism 10, such as Figure 1 - Figure 5As shown, the rotating mechanism 10 includes a base 11 and a rotating member 12. The base 11 has a rotating groove 111 on its back, and the groove wall of the rotating groove 111 forms an elastic positioning arm 1111. The rotating member 12 is rotatably disposed in the rotating groove 111, and a plurality of positioning structures 121 are formed on the rotating member 12. The plurality of positioning structures 121 are arranged at intervals around the rotation axis of the rotating groove 111. When the base 11 is rotated, the elastic positioning arm 1111 can move to cooperate with any of the positioning structures 121 to lock the relative position of the base 11 at the rotating member 12. This application solves the problems of complex rotation locking structures, cumbersome installation steps, and inconvenient assembly in the prior art for fixing devices of shooting brackets. This rotating mechanism 10 not only has a simple structure, fewer installation steps, and is easier to assemble, but also has a lower manufacturing cost.

[0034] Specifically, the back of the base 11 is provided with a rotating groove 111, and the groove wall of the rotating groove 111 forms an elastic positioning arm 1111; the rotating member 12 is rotatably disposed in the rotating groove 111. When the base 11 is rotated, the elastic positioning arm 1111 can move to cooperate with any positioning structure 121 to lock its position after rotating the base 11 by an angle. The locking method is achieved by the elastic positioning arm 1111 formed on the groove wall of the rotating groove 111 and the positioning structure 121 formed by the rotating member 12 itself. It can be completed without adding other components, the structure is simpler, the cost is lower, and unnecessary installation steps are eliminated. The assembly is completed by connecting the base 11 and the rotating member 12, and the assembly efficiency is higher.

[0035] Reference Figure 3 - Figure 5In one embodiment, the positioning structure 121 is a positioning groove 1211; the groove wall includes a bottom groove wall 1112, and a clearance groove 1112a is provided at the bottom groove wall 1112. The base 11 is hollow inside, and the clearance groove 1112a is connected to the inside of the base 11. One end of the elastic positioning arm 1111 is connected to the groove wall of the clearance groove 1112a, and the other end is suspended in the clearance groove 1112a. A positioning protrusion 1111a is provided on the other end, and the positioning protrusion 1111a is adapted to the positioning groove 1211. Thus, the positioning groove 1211 is formed by the rotating part 12 itself, achieving the same goal of eliminating parts and further improving assembly efficiency. Furthermore, the positioning groove 1211, in conjunction with the positioning protrusion 1111a, maintains the stability of the connection between the base 11 and the rotating part 12 after locking, preventing wobbling after the base 11 is locked. The clearance groove 1112a provides the elastic positioning arm 1111 with a certain deformation space. When the rotating part 12 is adjusted by force, the positioning protrusion 1111a is pressed, driving the other end of the elastic positioning arm 1111 to deform and bend inwards towards the base 11, achieving rapid disengagement from the current positioning groove 1211. After the external force is released, the elastic positioning arm 1111 resets using its own elastic potential energy, driving the positioning protrusion 1111a to re-engage with the next positioning groove 1211, completing the re-locking. The entire operation process is simple and efficient, with smoother adjustment and significantly reduced rotational jamming.

[0036] The length of the elastic positioning arm 1111 can be freely adjusted by those skilled in the art according to actual design requirements, and is not limited here. Specifically, its adjustment can follow the lever principle: by adjusting the length of the lever arm (i.e., the length of the elastic positioning arm 1111), the amount of external force required for rotation adjustment can be precisely controlled, so that the user can complete the rotation operation by applying an appropriate force, ensuring the feel of operation.

[0037] Reference Figure 4 Preferably, the elastic positioning arm 1111 extends along the rotation direction of the base 11. Thus, when the base 11 rotates, the force generated by the positioning protrusion 1111a and the rotating component 12 can be decomposed into two components: an axial force driving the elastic positioning arm 1111 to deform, and a tangential force along the rotation direction. Since the extension direction of the elastic positioning arm 1111 is consistent with the rotation direction of the base 11, the torsional stress generated by the tangential force is significantly reduced, reducing energy loss while improving force transmission efficiency. This ensures that the elastic positioning arm 1111 can fully deform and return to its original position, and effectively reduces the risk of structural fatigue damage.

[0038] Reference Figure 4 and Figure 5In one embodiment, the positioning protrusion 1111a has an arcuate surface 1111b, and the shape of the positioning groove 1211 is adapted to the arcuate surface 1111b. Thus, the positioning groove 1211 and the arcuate surface 1111b cooperate to guide the positioning protrusion 1111a into the positioning groove 1211, making locking more efficient and rapid. Furthermore, the arcuate surface 1111b reduces the coefficient of friction between the contact surfaces, reduces resistance during adjustment, and improves the smoothness of rotational adjustment.

[0039] Reference Figure 5 In one embodiment, the rotating member 12 is further provided with a plurality of guide grooves 122, with one guide groove 122 provided for every two adjacent positioning structures 121. The guide grooves 122 extend along the rotation path of the elastic positioning arm 1111 to guide the elastic positioning arm 1111 to alternately switch between the two positioning structures 121. Thus, when the elastic positioning arm 1111 disengages from the current positioning structure 121, the guide grooves 122 can limit the positioning protrusion 1111a, allowing the positioning protrusion 1111a to smoothly transition to the next positioning structure 121 along a preset trajectory. This effectively reduces the radial offset during the switching process, improves the alignment accuracy between the positioning protrusion 1111a and the positioning groove 1211, and further optimizes the smoothness of rotation adjustment.

[0040] Preferably, the width of the guide groove 122 is smaller than the width of the positioning protrusion 1111a. This ensures that when the positioning protrusion 1111a enters the guide groove, the guide groove 122 only partially contacts the protrusion, and the elastic positioning arm 1111, not fully inserted into the guide groove 122, moves towards the interior of the base 11, generating pre-deformation. At this time, the elastic potential energy of the elastic positioning arm 1111 is pre-stored, and when the positioning protrusion 1111a slides into the positioning groove 1211, the elastic positioning arm 1111 can quickly release energy and reset, improving locking efficiency.

[0041] Reference Figure 3 In one embodiment, two elastic positioning arms 1111 are provided, symmetrically arranged on both sides of the rotating groove 111. With this arrangement, when the base 11 is locked, the two elastic positioning arms 1111 simultaneously engage with the corresponding positioning grooves 1211, and the force is evenly distributed to both sides of the rotation center of the base 11, making the locking force of the base 11 more balanced and reducing the circumferential movement of the base 11 in the non-operating state.

[0042] It is understood that the number of flexible positioning arms 1111 can also be set to more than two. Those skilled in the art can adjust it according to actual design requirements, and no limitation is made here.

[0043] Reference Figure 3In one embodiment, the rotating mechanism 10 further includes an elastic damping pad 13, which is installed in the rotating groove 111 and sandwiched between the base 11 and the rotating member 12. This arrangement serves two purposes: firstly, the elastic damping pad 13 can absorb impact vibration energy, preventing the elastic positioning arm 1111 from undergoing plastic deformation due to impact loads, and simultaneously damping the base 11 to prevent excessive shaking when subjected to external forces; secondly, the elastic damping pad 13 can fill the installation gap between the base 11 and the rotating member 12 support 1000, eliminating axial shaking between the base 11 and the rotating member 12 and improving connection stability. Specifically, the elastic damping pad 13 can be made of silicone or rubber, and is not limited thereto.

[0044] Reference Figure 1 and Figure 2 The present invention also discloses a fixing device 100, which includes the rotating mechanism 10 of the above embodiments and is used to connect to the shooting equipment.

[0045] Reference Figure 6 and Figure 7 In one embodiment, the base 11 has storage slots 112 on both sides, and the fixing device 100 includes two grippers 20, which are respectively received in the two storage slots 112. The two grippers 20 are movably connected to the two storage slots 112, allowing both grippers to be exposed outside the base 11, thus defining a clamping space together with the base 11 for fixing the shooting device. With this configuration, the two grippers 20 can fix the shooting device by clamping; and when not in use, the two grippers 20 can be stored in the storage slots 112, reducing external space occupation and making the fixing device 100 more compact and easier to store.

[0046] In one embodiment, the gripper 20 further includes a connecting seat 21 and a clamping member 22. The connecting seat 21 is slidably connected to the base 11, and the clamping member 22 is rotatably connected to the connecting seat 21, so that the clamping member 22 can be screwed into or out of the storage groove 112. With this configuration, the two connecting seats 21 are slidably connected to the base 11 respectively, so that the two clamping members 22 can open relative to each other to accommodate shooting devices of different sizes.

[0047] In one embodiment, along the rotation axis of the clamping member 22, the gripper 20 includes two opposing sidewalls 221, each with a locking groove 2211. The receiving groove 112 includes a limiting surface 1121 opposite to the sidewalls 221, with a locking block 1121a on the limiting surface 1121. The locking block 1121a is located on the rotation path of the locking groove 2211, allowing the clamping member 22 to be screwed into the receiving groove 112, so that the locking block 1121a is locked in the locking groove 2211. This configuration, with the locking block 1121a cooperating with the locking groove 2211, ensures that the clamping member 22 remains in the receiving groove 112, preventing accidental loosening. Furthermore, without additional operation, locking is automatically completed at the final position of the clamping member 22 when screwed into the receiving groove 112, making operation more convenient.

[0048] In one embodiment, the fixing device 100 further includes a magnetic suction element (not shown in the figure), which is disposed on the base 11. The shooting device is placed on the base 11 and magnetically connected to the magnetic suction element. In this way, the fixing device 100 can also fix the shooting device through magnetic connection, which improves its adaptability.

[0049] This utility model also discloses a bracket 1000 (not shown in the figure), which includes the fixing device 100 of the above embodiments. There are many ways to set up the bracket 1000, such as a desktop bracket 1000, a neck bracket 1000, and a handheld bracket 1000, etc. The setting method of the bracket 1000 is not limited here.

[0050] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
