[0041] In order to meet the installation requirements of different scenes and users, existing cameras mainly adjust the shooting angle by adjusting the camera mounting bracket to achieve the requirements of a wide shooting angle range, stability, and easy adjustment. Among the existing adjustment brackets, some use multiple screws to lock and fix the ball head, but when adjusting the ball head, many parts need to be disassembled and assembled, and the adjustment process is cumbersome and costly; some use screws to drive the wedge structure to slide in the adjustment bracket to clamp or tighten the ball head, but the screw and the wedge structure are easily stuck through the threaded fit, resulting in the inability to adjust the ball head, and due to the torque of the electric screwdriver and manpower, the screw torque is insufficient, resulting in insufficient travel of the wedge structure and the inability to lock the ball head.

[0042] In order to solve the above problems, Figures 1 to 10 As shown, the utility model first provides a bracket, the adjustment process of the bracket is simple and convenient, and the locking effect can be guaranteed.

[0043] like Figure 1 to Figure 2As shown, specifically, the bracket includes a base component 1, an outer cover 2, a support member 3, a ball head component 4 and an adjustment component 5, wherein: the outer cover 2 is arranged on the base component 1, and the outer cover 2 is provided with an active cavity 21 and an opening 22 connected to an end of the active cavity 21 away from the base component 1; the support member 3 is arranged in the active cavity 21 and can slide relative to the outer cover 2; the ball head component 4 is arranged in the active cavity 21 and supported by the support member 3, and the ball head component 4 is connected to an external device through the opening 22; the adjustment component 5 includes a cam 51 arranged in the active cavity 21 and located on the side of the support member 3 away from the ball head component 4, the cam 51 can rotate relative to the outer cover 2, and has an unlocked state and a locked state; in the unlocked state, the ball head component 4 can move in the active cavity 21; in the locked state, the cam 51 pushes the support member 3 toward the side away from the base component 1 to limit the movement of the ball head component 4 in the active cavity 21.

[0044] In the bracket provided by the embodiment of the utility model, the camera body and other external devices are connected to the ball head assembly 4 through the opening 22. When the angle of the external device needs to be adjusted, the control cam 51 is rotated relative to the outer cover 2 to an unlocked state. At this time, there is a certain gap or slight contact between the cam 51, the support member 3, the ball head assembly 4 and the inner wall of the active cavity 21 on the side where the opening 22 is provided, so that the ball head assembly 4 can move in the active cavity 21, so that the angle of the external device can be adjusted by adjusting the ball head assembly 4; when adjusted to the desired angle, the control cam 51 is rotated relative to the outer cover 2 to a locked state. In this state, the cam 51 pushes the support member 3 toward the side away from the base assembly 1, so that the support member 3 slides toward the opening 22 and clamps the ball head assembly 4 with the inner wall of the active cavity 21 on the side where the opening 22 is provided. At this time, the ball head assembly 4 cannot move in the active cavity 21, so that the ball head assembly 4 and the external equipment can be locked at the adjusted angle; the adjustment process is simple and convenient, which is easy for users to operate, and the cam 51 will not get stuck during the rotation process, so as to avoid the phenomenon of being unable to adjust or locking failure, so as to ensure the locking effect and ensure the stability and reliability of the bracket in the locked state.

[0045] like Figure 3 and Figure 6 As shown, in the illustrated embodiment, the opening 22 is set as a waist-shaped opening extending along the ±X direction. In the unlocked state, the ball head assembly 4 can swing back and forth along the ±X direction at the waist-shaped opening, and the ball head assembly 4 can also rotate around its own axis Y to adjust the angle of the external device. Of course, in other embodiments, the opening 22 can also be set as a circular opening, an L-shaped opening or other shapes as needed, and the ball head assembly 4 can also move relative to the outer cover 2 in other ways in the active cavity 21 according to the shape of the opening 22, and the embodiment of the utility model does not make specific restrictions here.

[0046] like Figure 1 to Figure 2As shown, in the unlocked state, the outer cover 2 can rotate relative to the base assembly 1 around the axis Z, so that the bottom ball head assembly 4 rotates together with the outer cover 2 relative to the base assembly 1 around the axis Z to adjust the angle of the external device. In the locked state, the cam 51 pushes the base assembly 1 toward the side away from the outer cover 2, so that the outer cover 2 is pressed and fixed to the base assembly 1, and the friction between the outer cover 2 and the base assembly 1 can be increased to limit the rotation of the outer cover 2 relative to the base assembly 1. In this way, the rotation of the outer cover 2 relative to the base assembly 1 and the movement of the ball head assembly 4 in the active cavity 21 can be controlled simultaneously by an adjustment assembly 5; the number of parts is reduced, the adjustment process is further simplified, and the user operation is convenient. Among them, when the ball head assembly 4 swings to the waist-shaped mouth Figure 3 and Figure 6 In the position shown, the axis Y coincides with the axis Z.

[0047] like Figure 1 to Figure 2 As shown, specifically, the base assembly 1 includes a base body 12 and an abutment member 13 that enclose a mounting cavity 11, the base body 12 is provided with a mounting opening 121, and a step portion 23 is provided on a side of the outer cover 2 away from the opening 22, and the step portion 23 extends into the mounting cavity 11 through the mounting opening 121; the inner wall of the base body 12 is provided with a first tooth portion 122, and the first tooth portion 122 is located at the outer periphery of the mounting opening 121, and the step portion 23 is provided with a second tooth portion (not shown), and the cam 51 can push against the abutment member 13 through the mounting opening 121, so that the first tooth portion 122 is meshed with the second tooth portion. The abutment member 13 includes a fixing portion 131 and an abutment portion 132, and the abutment portion 132 can extend into the active cavity 21 through the mounting opening 121. In the unlocked state, there is a certain gap or slight contact between the cam 51 and the abutment portion 132, so that the first tooth portion 122 can be separated from the second tooth portion, and the outer cover 2 can rotate around the axis Z relative to the base assembly 1. In the locked state, the cam 51 pushes the abutment portion 132 toward the side away from the outer cover 2 , the base assembly 1 as a whole slides toward the side away from the outer cover 2 , and the first tooth portion 122 meshes with the second tooth portion to limit the outer cover 2 from rotating relative to the base assembly 1 .

[0048] The abutment member 13 and the base body 12 may be split structures and surrounded to form the installation cavity 11. The abutment member 13 may be fixedly connected to the base body 12 by fasteners such as screws, so as to facilitate the installation of the outer cover 2. During the installation process, the ball head assembly 4, the support member 3 and the cam 51 are first installed in the outer cover 2, and then the end of the outer cover 2 with the opening 22 is passed through the installation opening 121 from the bottom of the base body 12, and the step portion 23 is left at the bottom of the base body 12 and cooperates with the first tooth portion 122, and finally the abutment member 13 is installed to the bottom of the base body 12. Alternatively, the abutment member 13 may also be an integrated structure with the base body 12 and have the installation cavity 11.

[0049] like Figure 7As shown, in the illustrated embodiment, the cross section of the cam 51 is an ellipse, the minor axis size of the ellipse is A, the major axis size is B, and 0.8B<A<B is satisfied. This can increase the torque value of the cam 51 rotation and avoid excessive angular velocity of the cam 51, so that the user can control the cam 51. Figure 8 As shown, in the unlocked state, the two ends of the short axis of the elliptical cam 51 are respectively facing the support member 3 and the abutment member 13, and there is a certain gap or slight contact between the cam 51 and the support member 3 and between the cam 51 and the abutment member 13. Fig. 9 As shown, in the locked state, both ends of the major axis of the elliptical cam 51 abut against the support member 3 and the abutment member 13 respectively.

[0050] Of course, in other embodiments, the elliptical cam 51 can also be set to other sizes as needed, and the cam 51 can also be set to other regular or irregular shapes, as long as the cam 51 has a variable diameter and can push the support member 3 and the base assembly 1 to both sides when rotating from the unlocked state to the locked state, the embodiments of the utility model are not specifically limited here.

[0051] like Figure 7 As shown, the cam 51 includes two abutting surfaces 511 arranged opposite to each other. In the locked state, the two abutting surfaces 511 respectively abut against the support member 3 and the base assembly 1. In the illustrated embodiment, the two abutting surfaces 511 are respectively arranged at both ends of the long axis of the elliptical cam 51. The abutting surfaces 511 can improve the stability of the cam 51 when it abuts against the support member 3 and the abutting member 13, and prevent the cam 51 from accidentally rotating and causing locking failure, thereby improving the locking effect.

[0052] like Figure 1 and Figure 4 As shown, the adjustment assembly 5 further includes a shaft 52 and a handle 53. The shaft 52 is connected to the cam 51, and at least a portion of the shaft 52 is exposed from the active cavity 21. The handle 53 is located outside the outer cover 2 and is connected to the portion of the shaft 52 that is exposed from the active cavity 21. The shaft 52 is used to support the cam 51. The handle 53 is located outside the outer cover 2 to increase the length of the lever arm, making it easier for the user to control the adjustment assembly 5 and convenient for the user to operate. In addition, the handle 53 can also ensure the stopping force of the cam 51 on the support member 3 and the abutment member 13, making the bracket more stable and reliable in the locked state.

[0053] Among them, the number of cams 51 can be two, and the two cams 51 are arranged at intervals along the length direction of the rotating shaft 52. The two cams 51 can improve the balance and stability when the cams 51 push against the support member 3 and the abutment member 13, thereby preventing the support member 3 or the abutment member 13 from tilting and affecting the locking effect.

[0054] like Figures 1 to 3As shown, in one embodiment, the handle 53 is detachably connected to the rotating shaft 52. When the angle of the external device needs to be adjusted, the handle 53 is connected to the rotating shaft 52, and the handle 53 and the rotating shaft 52 are disassembled after the adjustment is completed, so that the space occupied by the bracket during use can be reduced, the appearance is neat, and the handle 53 can be prevented from being accidentally rotated and causing the locking failure.

[0055] Specifically, the portion of the rotating shaft 52 that is exposed from the active cavity 21 is provided with an insertion hole 521, and the handle 53 can be inserted into the insertion hole 521 and drive the rotating shaft 52 and the cam 51 to rotate around the axis of the rotating shaft 52. Among them, the cross-section of the insertion hole 521 and the handle 53 can be set to a non-rotating structure with a regular or irregular shape such as a hexagon, a pentagon, a square, a triangle, an ellipse, etc., as long as it is ensured that there is no slippage between the handle 53 and the rotating shaft 52. Alternatively, the handle 53 can also be detachably connected to the portion of the rotating shaft 52 that is exposed from the active cavity 21 by other means such as snap connection, magnetic attraction, etc., and the embodiment of the utility model is not specifically limited here.

[0056] Furthermore, the portion of the rotating shaft 52 exposed from the active cavity 21 is further provided with an indicator portion 522, which is used to remind the user of the rotation angle of the cam 51. The outer wall of the outer cover 2 may be provided with an indicator mark, such as an unlock mark and a lock mark. In the unlocked state, the indicator portion 522 points to the unlock mark, and in the locked state, the indicator portion 522 points to the lock mark, so that the user can control the adjustment component 5.

[0057] like Figures 4 to 6 As shown, in another embodiment, the handle 53 is fixedly connected to the rotating shaft 52, and one of the handle 53 and the outer cover 2 is provided with a slot 24, and the other is provided with an elastic clip 531. In the unlocked state, the elastic clip 531 is disengaged from the slot 24, and the handle 53 can drive the rotating shaft 52 and the cam 51 to rotate synchronously; in the locked state, the elastic clip 531 is clamped in the slot 24 to limit the rotation of the handle 53 relative to the outer cover 2, so as to avoid the handle 53 from rotating accidentally and causing the locking failure. The elastic clip 531 has a certain elasticity to ensure the stability and reliability when the elastic clip 531 is clamped with the slot 24. In addition, the user can choose the handle 53 that is fixedly connected or detachably connected to the rotating shaft 52 according to the use environment and other conditions, so as to broaden the use scenarios of the bracket and meet the different needs of users.

[0058] Furthermore, when the outer wall of the outer cover 2 is provided with an indication mark, such as an unlocking mark and a locking mark, in the unlocking state, the handle 53 points to the unlocking mark, and in the locking state, the handle 53 points to the locking mark, so that the user can control the adjustment component 5.

[0059] like Figure 5As shown, specifically, the outer cover 2 is provided with a card slot 24, the handle 53 is provided with a movable slot 532 and a cover plate 533 covering the movable slot 532 on a side of the outer cover 2, the cover plate 533 is provided with a through hole 5331 corresponding to the movable slot 532, the elastic clamping member 531 includes a clamping block 5311 and an elastic member 5312, the clamping block 5311 is slidably arranged in the movable slot 532, at least part of the clamping block 5311 can be exposed from the movable slot 532 through the through hole 5331, so as to be engaged with the card slot 24, the elastic member 5312 is arranged between the clamping block 5311 and the inner wall of the movable slot 532, and when the clamping block 5311 slides toward the movable slot 532, the elastic member 5312 is compressed. The size of the through hole 5331 is smaller than the size of the clamping block 5311, so as to prevent the clamping block 5311 from falling out of the movable slot 532. The elastic member 5312 enables the block 5311 to be reset in time, and can ensure the stability and reliability of the block 5311 when it is engaged with the slot 24. The block 5311 is preferably spherical, and when the spherical block 5311 abuts against the outer wall of the outer cover 2 and the edge of the slot 24, it can slide toward the movable slot 532, playing a guiding role, so that the user can control the handle 53.

[0060] like Figure 2 As shown, the support member 3 includes a support arc surface 31 facing the ball head assembly 4, and an inner wall of one side of the active cavity 21 having an opening 22 is provided with an abutting arc surface 212. In the unlocked state, there is a certain gap or slight contact between the support arc surface 31, the ball head assembly 4 and the abutting arc surface 212, so that the ball head assembly 4 can move smoothly in the active cavity 21 and is not prone to jamming. In the locked state, the support arc surface 31 and the abutting arc surface 212 clamp the ball head assembly 4 to limit the movement of the ball head assembly 4 in the active cavity 21, and the arc surface can increase the contact area between the support arc surface 31 and the abutting arc surface 212 and the ball head assembly 4 to enhance the locking effect and avoid the ball head assembly 4 from accidentally moving relative to the outer cover 2 due to insufficient locking force.

[0061] like Figure 1 to Figure 2 As shown, along the sliding direction of the support member 3, one of the inner wall of the active cavity 21 and the support member 3 is provided with a slide groove (not shown), and the other is provided with a slider 211 that can slide in the slide groove. The slider 211 cooperates with the slide groove to limit the movement direction of the support member 3, so that the support member 3 can only slide along the Z-axis direction, and can ensure the balance and stability of the support member 3, and prevent the support member 3 from rotating or tilting during the sliding process to affect the locking effect.

[0062] like Fig.10As shown, the ball head assembly 4 includes a ball head body 41 and a rubber part 42. The ball head body 41 includes a ball head 411 and a connecting part 412. The ball head 411 is arranged in the active cavity 21.
