FIG. 1 is a schematic perspective view of a hand-held pole assembly 1 of a pan-tilt head according to an embodiment of the present invention; FIG. 2 is a front view of a hand-held pole assembly 1 for a pan-tilt head according to an embodiment of the present invention; A cross-sectional view of a pan-tilt hand-held bar assembly 1 is provided. FIG. 4 is a cross-sectional view of a pan-tilt hand-held bar assembly 1 according to an embodiment of the present invention. The pan/tilt hand-held bar assembly 1 is mounted on the pan/tilt head 2, and the pan-tilt hand-held bar assembly 1 comprises:

Handle the pole 10,

a connector 20 mounted on the hand lever 10;

The connecting member 20 is movably connected to the hand-held bar 10 for abutting the pan-tilt 2 and detachably mounting the hand-held lever 10 on the pan-tilt head 2.

This embodiment does not limit the specific shape and structure of the pan/tilt. Those skilled in the art can set according to specific design requirements. For example, the pan/tilt can be set as a single-axis pan/tilt, two-axis pan/tilt or three-axis pan/tilt. Preferably, the pan/tilt head can be set to the three-axis pan/tilt head shown in FIG. 5.

The shape and the number of the hand-held pole assembly 1 of the pan-tilt are not limited in this embodiment, and those skilled in the art can set according to specific design requirements. For example, the pan-tilt hand-held bar assembly 1 can be set into a frame shape so that It is placed on the ground to support the pan/tilt, or the pan-tilt hand-held bar assembly 1 is set to one, two, three rod-shaped structures, etc., and preferably, the pan-tilt hand-held bar assembly 1 is set to There are two rod-shaped hand-held bars 10, which are respectively disposed on two sides of the pan-tilt, and the two hand-held bars 10 are on the same straight line.

The hand lever 10 of the embodiment is a cylindrical rod body, and the connecting member 20 is movably coupled to the hand lever 10. The connector 20 is slidable along the extending direction of the hand lever 10. The connecting member 20 is a cylindrical structure that can be sleeved on the hand lever 10. One end of the connecting member 20 is movably connected to the hand-held bar 10, and the other end is detachably fixed to the pan/tilt, so that the hand-held bar 10 is detachably mounted on the pan/tilt head.

In order to achieve a detachable connection of the connector 20 to the platform, the connector 20 includes a connection end 22. The connecting end 22 is located at one end of the hand-held bar 10, and the connecting end 22 is detachably connected to the pan/tilt head 2, so that the hand-held bar 10 is detachably mounted on the pan-tilt head 2 .

In some embodiments, the connecting end 22 may be a detachable connection manner such as a snap connection, a clamp connection, a snap connection, etc.; in this embodiment, the connection end 22 is screwed and connected to the cloud. The table is detachable. The connecting end 22 includes an internal thread for screwing with the pan/tilt to realize quick release and quick loading of the pan-tilt hand-held rod assembly 1 and the pan/tilt head with a simple structure.

The connecting member 20 is also movable on the hand-held lever 10, on the one hand, the hand-held lever 10 can be flexibly mounted, and on the other hand, when the hand-held lever 10 is mounted on the pan/tilt, the In the process of using, the vibration on the hand-held pole 10 can be reduced to the gimbal as much as possible, so that the operation effect of the gimbal is more stable.

Specifically, in the embodiment, in order to realize the sliding of the connecting member 20 along the extending direction of the hand-held bar 10 , the connecting member 20 includes an engaging end 24 along the connecting end 20 . The inner wall is formed to protrude in the radial direction to form a ring having a smaller inner diameter inside the connecting member 20. Of course, in other embodiments, the engaging end 24 may not be a ring structure, but one or more separate protrusions, or other structures capable of engaging in a card. Correspondingly, the hand-held bar 10 is provided with an engaging groove 12, and the length of the engaging groove 12 in the direction in which the hand-held bar 10 extends is greater than the length of the engaging end 24, so that the engaging The end 24 is slidable in the engaging groove 12 in a direction in which the hand lever 10 extends.

In some embodiments, the engaging groove 12 can be directly opened on the hand-held bar 10. In the embodiment, the hand-held bar 10 includes a fixing head 14 , and the fixing head 14 is sleeved in the hand-held At one end of the rod 10, the fixing head 14 has a shoulder 141, and the engaging groove 12 is formed at one end of the shoulder 141.

The PTZ hand-held lever assembly 1 can also be docked with the PTZ when installed on the PTZ to prevent the PTZ hand-held lever assembly 1 from sliding axially after the installation is completed, so that the user can perform misoperation and affect the cloud. The operational performance of the station.

In some embodiments, a plurality of rugged structures are formed on one end of the docking member 30 facing the gimbal. Correspondingly, one end of the gimbal is formed with a plurality of docking structures, and the two are docked with each other. The axial movement is limited to avoid rotation of the handrail 10 about its axis. In this embodiment, a toothed disc 32 is disposed on a side of the docking member 30 facing away from the hand-held lever 10. The corresponding position of the pan/tilt is provided with mating teeth that can engage with the toothed disc 32. When the pan-tilt hand-held bar assembly 1 is mounted on the pan/tilt head, the docking member 30 and the mating teeth on the pan-tilt head mesh with each other, thereby preventing the pan-tilt hand-held bar assembly 1 from being freely rotated about the axis direction, so that The pan/tilt hand lever assembly 1 The connection to the gimbal is more stable.

The docking member 30 is mounted on the fixing head 14 at the end of the hand lever 10. Specifically, the screw can be passed through the docking member 30 to be fixed to the fixing head 14 by means of a screw connection. Further, the outer diameter of the abutting member 30 is larger than the outer diameter of the end of the fixing head 14 to the shoulder 141 of the fixing head 14, so that the engaging groove 12 is formed on the abutting member 30 and the Between the shoulders 141. Therefore, the engaging end 24 of the connecting member 20 can slide between the abutting member 30 and the shoulder 141.

Further, an elastic element 50 may be disposed between the abutting member 30 and the engaging end 24 of the connecting member 20. The elastic member 50 may be a member having a compressive elasticity such as a spring or an elastic column. One end of the elastic member 50 abuts against the abutting member 30 , and the other end abuts against the engaging end 24 of the connecting member 20 .

When the pan/tilt hand lever assembly 1 is not required to be mounted, the connecting member 20 is contracted toward the end of the hand-held lever 10 by the elastic force of the elastic member 50; when the pan-tilt hand-held lever assembly 1 needs to be installed The docking member 30 is firstly connected to the structure to be installed. In this embodiment, the structure to be installed is a pan/tilt head. After the docking is stabilized, the handrail 10 is oriented away from the hand-held pole 10 along the axial direction of the hand-held lever 10. Pulling the connecting member 20 in the direction (ie, the direction of the hand-held bar 10 in the axial direction of the pan-tilt), the elastic member 50 is gradually compressed at the same time, so that the connecting member 20 gradually approaches the pan/tilt, and rotates the The connecting member 20 is configured to screw the connecting end 22 to the pan/tilt head, thereby completely fixing the pan-tilt hand-held lever assembly 1 to the pan/tilt head.
