In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

As shown in fig. 1, 2 and 3, the locking device of the pan/tilt head according to the embodiment of the present invention includes: the cloud platform comprises a cloud platform base 10, wherein the cloud platform base 10 is provided with an accommodating cavity 11; the ball body 20 is movably connected in the accommodating cavity 11; the locking seat 30 is movably arranged in the accommodating cavity 11, a locking part 31 matched with the ball 20 is arranged on the locking seat 30, and the locking seat 30 can move towards the ball 20 and lock the ball 20 to limit the relative movement of the cloud base 10 and the ball 20; the driving member 40 is rotatably sleeved on the cloud base 10 and is in transmission connection with the locking base 30.

It will be appreciated that the locking portion 31 is shaped as an inwardly concave spherical surface that fits into the ball 20.

It should be noted that, in some embodiments of the present invention, the quick-assembling device 12 is mounted on the bottom of the cloud base 10, the bottom of the ball 20 has a base 21, and the base 21 is provided with a threaded hole 211 for connecting with a tripod. Of course, in some embodiments, the quick-assembly device 12 may be mounted on the ball 20, and the head mount 10 may be mounted on a tripod, which is not limited herein.

According to the cloud platform locking device of the embodiment of the invention, the driving member 40 rotates relative to the cloud platform base 10 to drive the locking base 30 to move towards the ball 20 and lock the ball 20, so that the relative movement of the cloud platform base 10 and the ball 20 is limited. Compared with the prior art, among this technical scheme, through locating cloud platform seat 10 with driving piece 40 rotationally the cover, in operation process, driving piece 40 need not to receive the influence of mounting structure and position, can the arbitrary direction rotate driving piece 40 and adjust the photographic demand in order to satisfy different angles to the cloud platform, simple structure and simple operation.

In the prior art, a structure that a screw is used for loosening and tightening a sphere 20 is adopted, when an angle needs to be adjusted, the screw can be screwed only by large force in an initial state, and therefore, in the first step, a user needs to hold a support of a tripod (preventing the tripod from toppling over due to excessive force) with one hand and rotate the screw with the other hand to slightly loosen the screw without completely loosening the locking of the sphere 20; in the second step, the hand holding the tripod is released, the ball 20 or the quick-mount device 12 on which the camera or the like is mounted is held to rotate, and then the screw is rotated by the other hand to lock the ball 20 (at this time, the rotation is performed with only a slight effort), thereby adjusting the shooting angle. However, in the first step of the above operation process, when the screw is loosened too much, the user cannot stabilize the ball 20 or the quick-assembly device 12 in time, so that the rotation angle is too large, and the camera and other objects fall down. In some embodiments of the present invention, an operator can rotate the driving member 40 with one hand and hold the sphere 20 or the quick-assembly device 12, and hold the tripod with the other hand to adjust the shooting angle, so that even if the driving member 40 is unscrewed excessively, the operator can stabilize the sphere 20 or the quick-assembly device 12 in time, and prevent objects such as a camera from falling off, and the present invention is safe and reliable.

As shown in fig. 1 to 7, in some embodiments of the present invention, the driving member 40 is in driving connection with the locking seat 30 through a driving structure, and the driving is reliable. In a specific embodiment, the transmission structure includes a sliding seat 61 slidably disposed in the accommodating cavity 11, the sliding seat 61 is located above the locking seat 30, a driving portion 411 extends radially inside the driving member 40, a width of the driving portion 411 gradually widens from one end to the other end, the driving portion 411 rotates to cooperate with the sliding seat 61 to drive the locking seat 30 to move toward the ball 20 and lock the ball 20, so as to play a role in fastening or loosening the ball 20 in the pan-tilt locking device, the transmission is reliable, and the stability is high. It will be appreciated that the driving member 40 drives the sliding seat 61 to move laterally, thereby pushing the locking seat 30 to move towards the ball 20; the width of the driving part 411 is gradually increased from one end to the other end to be gradually increased from left to right.

It is understood that in some embodiments, the driving member 40 is rotatably sleeved on the cloud platform base 10, and the driving member 40 and the cloud platform base 10 are in threaded adjustment and engagement, and the transmission structure is an extending pushing block connected to the driving member 40, and the extending pushing block is located above the locking base 30. This is still achieved when the driving member 40 is rotated relative to the cloud base 10 and pushes the locking socket 30 towards the ball 20 by extending the pushing block and locking the ball 20.

As shown in fig. 2 to 7, in some embodiments of the present invention, the sliding seat 61 is rotatably provided with a rotating wheel 62, the driving portion 411 has an inner concave surface 4111 matched with the rotating wheel 62, a radial dimension of the driving portion 411 increases or decreases in a circumferential direction, and a length of the inner concave surface 4111 is greater than an outer diameter of the rotating wheel 62. When the cloud platform is locked, as the driving member 40 rotates relative to the cloud platform 10, the rotating wheel 62 abuts from the concave curved surface 4111 at the shorter width of the driving portion 411 to the concave curved surface 4111 at the longer width of the driving portion 411, so as to drive the sliding seat 61 to move laterally, thereby pushing the locking seat 30 to move gradually toward the ball 20 and locking the ball 20. It can be understood that, in the process of the above gradual locking, since the length of the concave cambered surface 4111 is greater than the outer diameter of the rotating wheel 62, the driving distance is relatively long, and through the change of the radian of the concave cambered surface 4111, the driving portion 411 of the driving member 40 slowly applies pressure to the sliding seat 61, so that the user can conveniently rotate the driving member 40, and the operation is convenient and labor-saving.

In some embodiments of the present invention, a positioning sliding groove 14 is disposed in the accommodating cavity 11 of the pan/tilt/zoom holder 10, an upper portion of the sliding seat 61 is embedded in the positioning sliding groove 14, and a lower portion of the sliding seat 61 abuts against the locking seat 30, so as to perform a positioning function and prevent the sliding seat 61 from moving left and right.

It should be noted that, a first spring 50 is arranged between the locking seat 30 and the pan/tilt head seat 10, so as to play a role of buffering and damping; a second spring 63 is disposed between the sliding seat 61 and the pan/tilt head seat 10, and when the driving member 40 rotates in the opposite direction, the second spring 63 can drive the sliding seat 61 to move towards the driving portion 411, so that the locking seat 30 releases the locking of the ball 20.
