Detailed ways

As shown in Figure 1, Figure 2, Figure 3, Figure 4, and Figure 5, the utility model includes a panel base assembly 1, a main body 2, a sphere upper gasket 3, a sphere 4, a sphere lower gasket 5, a locking block 6, an adjustment knob Twist assembly and platform base assembly 9, locking block 6 is positioned at sphere lower washer 5 lower ends, and described locking block 6 is the locking ring of an open hoop shape, and the material of this locking block 6 can be metal, also can It's plastic. Two sides of the opening 61 of the locking block are respectively provided with a vertical groove 62 and a slanted groove 63 , wherein the angle of the slanted groove is not limited. In order to protect the vertical groove or the inclined groove from being worn, a spacer 64, 65 can be added respectively in the above two grooves. The shapes of the above-mentioned gaskets 64, 65 are respectively matched with the vertical groove and the inclined groove and fixed therein. The fixing method can be It can be fixed with screws, can also be fixed with glue, and can also be fixed in other ways. The main body 2 is provided with holes 21 and 22 corresponding to the positions of the above two grooves. The adjusting knob assembly includes a locking knob assembly 7 and a damping adjusting knob assembly 8. The screw rod 71 in the locking knob assembly 7 passes through The hole 22 corresponding to the locking block chute 63 on the main body is matched with the locking block chute 63 or the washer 65, and the screw rod 81 in the damping adjustment knob assembly 8 passes through the hole 21 on the main body opposite to the vertical groove and locks Tight block vertical groove 62 or spacer 64 cooperate.

In order to improve the flexibility of the pan-tilt assembly, the number of the above-mentioned vertical slots and inclined slots can be more than two, and the positional relationship of each slot is not limited, that is, the vertical slots and inclined slots can be distributed at any angle; correspondingly, on the main body Holes or slots are provided corresponding to the positions of the slots. During use, the locking knob assembly and the damping adjustment knob assembly are installed by selecting different angles through the holes on the main body corresponding to each slot.

In order to make the screw rod 71 in the locking knob assembly 7 push up the locking block more smoothly and smoothly during the advancing process, an inclined plane insert 10 is added between the screw rod 71 and the chute 63 or the washer 65 . The slope of the sloped insert 10 matches with the locking block chute 63 or the washer 65 , and the other end of the sloped insert cooperates with the screw rod 71 of the locking knob assembly.

In the specific operation process, when it is necessary to lock the head, rotate the locking knob assembly 7, and the screw rod 71 will be pushed forward. piece 65, so that the locking block 6 is pushed up, and the locking block 6 pushes up the lower gasket 5 of the sphere. Since the sphere 4 is limited in the main body 2, the sphere 4 is finally locked in the main body; if the user does not want to Lock the pan-tilt, but hope that the pan-tilt can rotate freely, then rotate the damping adjustment knob assembly 8 according to the needs of the user, because the screw rod 81 withstands the vertical groove 62 or the gasket 64, when the screw rod 81 pushes forward, the lock will be locked. The tight block 6 is extruded and deformed, and after the inner diameter of the locked block 6 becomes smaller, the lower washer 4 of the ball pushes up, but the upward displacement changes slightly with the advancement of the screw rod 81, thereby achieving the effect of fine-tuning the damping.

As shown in Figure 2, Figure 3, Figure 6 and Figure 7, Figure 8-Figure 10, in order to prevent the adjustment knob from falling off from the main body, an anti-rotation structure is provided in the locking knob assembly 7 and the damping adjustment knob assembly 8 . Preventing the screw head from unscrewing is achieved in the following manner: the heads of the screw rods 71, 81 are provided with unthreaded steps 711, 811, the support sleeves 74, 84 are internal and external thread structures, and the support sleeves 74, 84 are connected to the main body through external threads. The holes 21, 22 on the top are matched and fixed on the main body, and the internal threads are matched with the threads 712, 812 on the screw rods 71, 81. During operation, the rotating nut, because there is a section of unthreaded step 711,811 on the screw rod 71,81, so the screw rod 71,81 cannot be unscrewed from the support sleeve 74,84, and the support sleeve 74,84 is fixed on the main body again, so The screw rods 71, 81 will not fall off from the main body. Prevent the screw rod root from being unscrewed in the following ways: 1. As shown in Figure 6 and Figure 7, grooves 713 and 813 are provided at the root of the screw rods 71 and 81, and grooves 713 and 813 are provided on the nuts 72 and 82 relative to the grooves 713 and 813. There are screw holes 721 , 821 through which locking screws 73 , 83 are clamped in the grooves 713 , 813 . In the above structure, because the locking screws 73, 83 clamp the screw rod in the nut through the grooves 713, 813, the screw rod will not fall out from the nut. 2. As shown in Fig. 8 and Fig. 9, the radial section of the roots 714, 814 of the screw rods 71, 81 is polygonal, and the roots are fixedly connected to the nuts 72, 82 by screws 76, 86. The aforementioned polygon may be a square, a pentagon, a hexagon, or the like. 3.
