DETAILED DESCRIPTION

[0026] Example

[0027] Please refer to Figure 1-Figure 6 A pan / tilt head includes an outer bracket 1 with a through hole, the through hole of the outer bracket 1 is provided with a hemispherical swivel bracket 6, the outer bracket 1 is an L-shaped plate, the through hole is opened in the transverse part of the outer bracket 1, and the outer bracket 1 and the swivel bracket 6 are detachably connected by bolts.

[0028] The slot of the swivel bracket 6 is rotatably provided with a hemispherical damping swivel 7, and the slots of the damping swivel 7 and the swivel bracket 6 are oriented in the same direction, the centers of the damping swivel 7 and the swivel bracket 6 are in the same vertical direction, the slot of the damping swivel 7 is provided with a swivel positioning piece 14 abutting against it, the contact surface between the swivel positioning piece 14 and the damping swivel 7 is coated with damping grease to form a damping grease layer 12, and the damping swivel 7 is provided with a mounting assembly for an external projector.

[0029] The above-mentioned swivel positioning member 14 is penetrated by an adjusting screw 4, one end of the above-mentioned adjusting screw 4 sequentially passes through the above-mentioned damping swivel 7 and the above-mentioned swivel bracket 6 and is threadedly engaged with an adjusting knob 2. The adjusting screw 4 can be extended and retracted relative to the swivel positioning member 14, the damping swivel 7 and the swivel bracket 6, and the above-mentioned adjusting knob 2 and the above-mentioned swivel bracket 6 are abutted and engaged, and the other end of the above-mentioned adjusting screw 4 is threadedly engaged with a hexagonal nut 11.

[0030] The diameter of the hole in the damping turret 7 and the turret bracket 6 through which the adjusting screw 4 passes is much larger than the diameter of the adjusting screw 4, so that the damping turret 7 can swing.

[0031] The adjusting screw rod 4 is fixedly sleeved with a polygonal positioning nut 13, the swivel bracket 6 is provided with a polygonal adjusting groove which is telescopically matched with the polygonal positioning nut 13, and the outer ring surface of the polygonal positioning nut 13 is in contact with the side wall of the polygonal adjusting groove.

[0032] The polygonal positioning nut 13 and the polygonal adjusting groove are both hexagonal structures. This design ensures that the adjusting screw 4 cannot rotate on its own but can only move along its axis.

[0033] The tightening of the utility model is as follows: the adjusting knob 2 is made to be tightly attached to the swivel bracket 6, the adjusting knob 2 is rotated to pull the adjusting screw 4 toward the adjusting knob 2, the polygonal positioning nut 13 moves in the polygonal adjustment groove, so that the hexagonal nut 11 pushes the swivel positioning piece 14 to be pressed tightly on the damping swivel 7, and the damping swivel 7 is pressed tightly on the swivel bracket 6, thereby realizing the locking of the projector connected to the damping swivel 7.

[0034] The utility model is loosened by rotating the adjusting knob 2 away from the swivel bracket 6, and the adjusting knob 2 rotates relative to the adjusting screw 4. When the gap between the adjusting knob 2 and the swivel bracket 6 is distributed on the sides, the gap can allow the adjusting screw 4 to move vertically, so that the hexagonal nut 11 will not press the swivel positioning piece 14, and the swivel positioning piece 14 and the swivel bracket 6 will not clamp and position the damping swivel 7, so that the projector on the damping swivel 7 can move.

[0035] When the damping rotary head 7 is in a loose state, the damping grease layer 12 is sticky and can realize the connection between the damping rotary head 7 and the rotary head positioning piece 14, so that when the rotary head positioning piece 14 is loosened, it can also be kept fixed by the viscosity of the damping grease layer 12. The projector connected to the damping rotary head 7 will not become loose directly, but will rotate to the desired set position when subjected to force, and then be locked by adjusting the knob 2. Compared with the traditional adjustment method, it has the advantage of stable adjustment and will not cause secondary damage due to the projector being too loose.

[0036] In some embodiments of the present invention, the outer bracket 1 is provided with an arc-shaped groove 5 , and the adjusting knob 2 is provided with a slider 3 rotatably matched with the arc-shaped groove 5 .

[0037] In the above embodiment, the rotational cooperation between the arc groove 5 and the slider 3 makes the rotational stability of the adjusting knob 2 higher.

[0038] When the utility model is in a locked state, the slider 3 is connected to one end of the arc groove 5. When the utility model is loosened, the slider 3 moves toward the other end of the arc groove 5. When the locking and positioning of the adjustment knob 2 is repeatedly performed, the slider 3 only needs to be moved to a position abutting against the end of the arc groove 5 to achieve accurate reset.

[0039] There are two groups of arc grooves 5 , and the coordinated sliding structure of the two groups of arc grooves 5 and the slider 3 further improves the stability of the rotation of the adjusting knob 2 .

[0040] In some embodiments of the present invention, the installation assembly includes a connecting piece 10 disposed outside the notch of the damping rotor 7 , and the connecting piece 10 is penetrated by a connecting bolt 8 .

[0041] In the above embodiment, the connecting piece 10 and the damping rotary head 7 are detachably connected via a bolt group, and the connecting bolts 8 on the connecting piece 10 are used for externally connecting to a projector, thereby realizing the connection between the utility model and the projector.

[0042] The connecting piece 10 is adapted to the notch of the damping rotor 7 , so that the connecting piece 10 can just seal the outside of the notch of the damping rotor 7 .

[0043] In some embodiments of the present invention, a rubber gasket 9 is provided on the outer side of the connecting piece 10 .

[0044] In the above embodiment, the design of the rubber gasket 9 realizes elastic buffering between the projector and the pan / tilt head, and the rubber gasket 9 can prevent scratches on the contact surface when the projector and the utility model are connected.

[0045] In some embodiments of the present invention, the turret bracket 6 and the outer bracket 1 are detachably connected via a bolt group.

[0046] In the above embodiment, the connection mode of the bolt group can realize the rapid installation and disassembly of the turret bracket 6 and the outer bracket 1.

[0047] There are multiple bolt groups, which improves the stability of the connection between the turret bracket 6 and the outer bracket 1.

[0048] In some embodiments of the present utility model, the outer bracket 1 is provided with a mounting groove, and the turret bracket 6 is butt-matched with the mounting groove;

[0049] The installation groove is provided with a docking block 15 , and the turret bracket 6 is provided with a docking groove 16 that docks and cooperates with the docking block 15 .

[0050] In the above embodiment, the mounting groove is a circular groove, which is suitable for the installation of the hemispherical turret bracket 6. The docking cooperation between the docking block 15 and the docking groove 16 can prevent the turret bracket 6 from rotating relative to the outer bracket 1, further improving the stability of the installation of the turret bracket 6.

[0051] There are two docking blocks 15 , which are symmetrically arranged about the middle of the installation slot. The design of two groups of docking blocks 15 and docking slots 16 has better stability.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
