[0007] The bottom surface of the ball bowl is provided with a plurality of latching teeth, the limiting member is engaged with one of the latching teeth, and when the user presses the limiting member downward, the limiting member is disengaged from the latching teeth;

[0008] Specifically, the pan head is installed on the bowl, and when the angle of the support leg needs to be adjusted, the limiter is pressed downward to disengage the limiter from the latch, and the limiter is no longer used to limit the support leg, thereby facilitating the adjustment of the angle of the support leg.

[0009] When the angle adjustment of the supporting leg is completed, release the limit piece. Under the push of the elastic force of the elastic piece, the limit piece can automatically reset upward and re-contact the latch tooth to limit the supporting leg, thereby completing the function of canceling the limit with one button and releasing it to re-limit, which is convenient and quick.

[0010] Preferably, the limiting member includes a rack button and a rack locking block, the rack button is vertically slidably connected inside the slide slot, the rack locking block is fixed to the rack button, and the elastic member is fixed between the bottom of the rack locking block and the inner bottom surface of the slide slot, and the top of the rack locking block has a tooth-shaped protrusion.

DETAILED DESCRIPTION

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0022] like Figures 1 to 5 The angle adjustment mechanism for a pan / tilt tripod shown in the figure comprises a ball bowl 1, three special-shaped upper inserting frames 2 are hingedly connected to the surface of the ball bowl 1, a supporting leg is fixed to the bottom of the special-shaped upper inserting frame 2, a sliding groove 3 is opened on the surface of the special-shaped upper inserting frame 2, a limit piece is vertically slidably connected in the sliding groove 3, and an elastic piece 8 is fixed between the limit piece and the inner bottom surface of the sliding groove 3;

[0023] The bottom surface of the bowl 1 is provided with a plurality of latching teeth 4, and the limiting member is engaged with one of the latching teeth 4. When the user presses the limiting member downward, the limiting member is disengaged from the latching teeth 4;

[0024] As an optional embodiment, the latch teeth 4 have three;

[0025] As an optional embodiment, the elastic member 8 can be an elastic pusher such as a spring or an elastic strip. Figure 2 Shown in is a spring;

[0026] Specifically, the pan head is installed on the bowl 1. When the angle of the support leg needs to be adjusted, the limiter is pressed downward to disengage the limiter from the latch 4, and the limiter is no longer used to limit the support leg, thereby facilitating the adjustment of the angle of the support leg.

[0027] When the angle adjustment of the supporting leg is completed, the limiting member is released. Under the elastic force of the elastic member 8, the limiting member can automatically reset upward and re-contact the latch 4 to limit the supporting leg, thereby completing the function of canceling the limit with one button and releasing and re-limiting, which is convenient and quick;

[0028] Compared with the existing tripods that can be installed on the ground, since the ground placement is only suitable for flat ground, when the tripod is used on a ground with complex terrain, the limit piece can be engaged with the latch 4 to complete the angle positioning of the support legs, thereby ensuring the stability of the tripod. After removing the restrictions of the ground placement or the center placement, the angle between the support legs and the ball bowl 1 can be set larger, thereby lowering the ball bowl 1. It can be seen that the device has a wider range of applications, a fast adjustment speed, a wider adjustment range, and high portability.

[0029] As a further implementation scheme of the utility model, the limiter comprises a rack button 5 and a rack locking block 6, the rack button 5 is vertically slidably connected inside the slide slot 3, the rack locking block 6 is fixed to the rack button 5, and the elastic member 8 is fixed between the bottom of the rack locking block 6 and the inner bottom surface of the slide slot 3, and the top of the rack locking block 6 has a toothed protrusion 7;

[0030] It should be noted that a positioning shaft 601 is provided between the rack locking block 6 and the rack button 5, and the rack locking block 6, the rack button 5 and the positioning shaft 601 are connected into a whole by a positioning and tightening screw;

[0031] Specifically, in the limited position, the rack lock block 6 is pushed by the elastic force of the elastic member 8 to contact the latch 4, and the latch 4 and the tooth-shaped protrusion 7 cooperate to limit the external turning of the special-shaped upper rack 2, thereby facilitating the storage state of the entire device;

[0032] When the bracket legs need to be turned outward, the rack button 5 is pressed downward, and the rack locking block 6 is driven to move downward as a whole through the rack button 5, so that the toothed protrusion 7 on the top of the rack locking block 6 is disengaged from the latching tooth 4. At this time, the special-shaped upper rack 2 can rotate freely, so that the angle of the supporting leg can be adjusted by adjusting the angle of the special-shaped upper rack 2.

[0033] As a further embodiment of the present invention, the tooth-shaped protrusion 7 has a first inclined surface 701 on the side close to the center of the bowl 1, and the latch 4 has a second inclined surface 401 on the side away from the center of the bowl 1;

[0034] Specifically, when the supporting legs need to be stored, the limit on the special-shaped upper rack 2 can be cancelled by pressing the rack downward, or the supporting legs can be directly pushed to the side close to the center of the bowl 1. Under the guidance of the first inclined surface 701 and the second inclined surface 401, the rack locking block 6 can be pushed downward to make way, thereby canceling the limit on the special-shaped upper rack 2.

[0035] As a further embodiment of the utility model, the utility model further comprises a handle 9, the handle 9 is fixed on the bowl 1, and a plurality of mounting holes 10 are formed on the handle 9;

[0036] Specifically, the handle 9 is fixed to the bowl 1 by screws, and there are redundant mounting holes 10 on the handle 9, which can be used to expand more devices to improve the user experience.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements fall within the scope of the utility model to be protected.
