[0030] See also Figures 1 to 4 The utility model provides a photographic support device, comprising a support base 1, a pan head assembly 2 installed on the top of the support base 1, and a clamping assembly 3 installed on the top of the pan head assembly 2; the pan head assembly 2 comprises a first connecting seat 21 and a first rotating seat 22, the first connecting seat 21 is connected to the support base 1, and the first connecting seat 21 is extended to be provided with two side walls 21a, the first rotating seat 22 is connected between the two side walls 21a through a rotating shaft 23, and can rotate around the rotating shaft 23; the first A rotating seat 22 is provided with a rotating shaft hole 22a, and the rotating shaft 23 is loosely fitted in the rotating shaft hole 22a. A conical groove is provided at one end of the rotating shaft hole 22a, and a first pin 24 is slidably installed in the conical groove. One end of the rotating shaft 23 is also connected to a first locking knob 25 through a thread. The rotating shaft 23 passes through the rotating shaft hole 22a and the first pin 24 in sequence and is connected to the first locking knob 25. The first locking knob 25 is used to squeeze the first pin 24 to lock the first rotating seat 22.

[0031] Specifically, the support base 1 is arranged at the bottom of the overall structure to support the remaining components. The pan-tilt assembly 2 is installed on the support base 1 through connecting parts such as screws 29a. As a structure for directly or indirectly clamping photographic equipment, it can drive the photographic equipment to move relative to the support base 1. In this embodiment, the rotating seat on the pan-tilt assembly 2 can rotate 180 degrees forward and backward around the rotating shaft 23 on the first connecting seat 21 to adjust the pitch angle of the photographic equipment.

[0032] Furthermore, two side walls 21a extend upward on both sides of the first connecting seat 21, and a space is formed between the two side walls 21a for the rotating seat to extend into. The rotating seat is partially inserted between the two side walls 21a, and the rotating seat is constrained in this space through the cooperation of the rotating shaft 23 and the rotating shaft hole 22a. The rotating shaft 23 is a quarter screw 33, which can be fixed between the two side walls 21a by welding, integral molding, etc.

[0033] Furthermore, the diameter of the tapered groove gradually increases along the direction close to the opening of the shaft hole 22a, and the first pin 24 has a certain elastic property. The first pin 24 is squeezed by the knob to clamp the first pin 24 between the shaft 23 and the groove wall of the tapered groove. The first pin 24 fills the gap between the shaft 23 and the tapered groove to eliminate the rotation space of the rotating seat, thereby preventing the rotating seat from continuing to rotate around the shaft 23. Among them, one end of the shaft 23 can extend from the side wall 21a to connect to the first locking knob 25, which is more convenient for users to operate. The first pin 24 and the first locking knob 25 can also be set between the two side walls 21a, thereby improving the compactness of the overall structure and the occupied space.

[0034] The present invention is described in more detail below by way of examples. However, the following examples are merely illustrative and should not be construed as limiting the scope of the present invention. Obviously, those skilled in the art may make any changes, improvements or modifications without violating the spirit of the present invention.

[0035] See also Figures 1 to 4 This example provides a rotation and locking principle of a gimbal assembly 2. A pin for angle locking is provided inside the gimbal rotation assembly. The pin is sleeved outside the shaft 23 to be installed at the end of the shaft hole 22a of the rotating seat. When the first locking knob 25 rotates forward, the knob rotates to squeeze the first pin 24, and the first pin 24 is engaged in the conical groove, so that the shaft 23 and the rotating seat are locked with each other, ensuring that the rotating seat no longer rotates in a circumferential direction, avoiding the situation where the device still shakes after the user reaches the desired pitch angle for shooting. When the angle needs to be adjusted, the first locking knob 25 is rotated in the opposite direction, and the first pin 24 is disengaged from the abutment of the first locking knob 25. At this time, the rotating seat is disengaged from the lock and can rotate. During the rotation process, the first pin 24 is pushed away from the conical groove under the action of the conical groove.

[0036] See also Figures 1 to 3 In this embodiment, conical grooves are provided at both ends of the shaft hole 22a, and a second pin 26 is provided in the conical groove at the end of the shaft hole 22a away from the first pin 24, and the second pin 26 and the first pin 24 are symmetrically arranged.

[0037] Among them, the second pin 26 has the same structure as the first pin 24 and is symmetrically arranged. When the first locking knob 25 squeezes the first pin 24, the end of the other end of the shaft 23 cooperates with the side wall 21a of the tapered groove to squeeze the second pin 26, so that the end of the shaft hole 22a away from the first pin 24 is also tightened synchronously.

[0038] See also Figures 1 to 3 In this embodiment, the first pin 24 and the second pin 26 are both of a conical structure. The conical pin can better match the shape of the conical groove, so that it can slide more smoothly in the conical groove and cling to the groove wall.

[0039] See also Figures 1 to 3 In this embodiment, the rotating shaft 23 and the first locking knob 25 are provided with secondary locking holes 29, and the secondary locking holes 29 are used to install screws 29a. The secondary locking holes 29 are arranged at positions where the rotating shaft 23 and the first locking knob 25 are relative to each other, so that the screws 29a are inserted from the outside of the first locking knob 25 and connected to the rotating shaft 23, so that the user cannot rotate the first locking knob 25 before removing the screws 29a, further improving the stability of the rotating seat.

[0040] See also Figures 1 to 3 In this embodiment, a fixing hole 21b and an avoidance hole 21c are respectively provided on the two side walls 21a of the first connection seat 21. One end of the rotating shaft 23 is clamped in the fixing hole 21b, and the other end of the rotating shaft 23 extends out of the avoidance hole 21c and is connected to the first locking knob 25. The fixing hole 21b is used to fix the rotating shaft 23. In this embodiment, the end of the rotating shaft 23 is transitionally matched with the fixing hole 21b through the second pin 26 so as to be tightly clamped. The rotating shaft 23 and the second pin 26 are clamped by a hexagonal nut and a hole of a corresponding shape. The avoidance hole 21c is used for the rotating shaft 23 to extend. The extended rotating shaft 23 can be more conveniently connected to the first locking knob 25, which is convenient for users to use and operate.

[0041] See also Figures 1 to 3 In this embodiment, the ends of the first pin 24 and the second pin 26 are both provided with positioning protrusions 27, and the fixing hole 21b and the avoidance hole 21c are correspondingly provided with positioning holes 28 that cooperate with the positioning protrusions 27. The positioning protrusion 27 is a square protrusion extending in the vertical direction, and the positioning hole 28 is a through hole corresponding to the shape and position of the positioning protrusion 27. Through the cooperation of the positioning hole 28 and the positioning protrusion 27, the installation convenience of the first pin 24 and the second pin 26 is further improved.

[0042] See also Figures 1 to 4In this embodiment, the clamping assembly 3 includes a second connecting seat 31 and a second rotating seat 32. The second connecting seat 31 is connected to the top of the pan / tilt assembly 2. A clamping plate 32a for clamping photographic equipment is provided on one side of the second rotating seat 32, and the second rotating seat 32 is rotatably connected to the second connecting seat 31. The design of the second connecting seat 31 and the second rotating seat 32 allows the photographic equipment to be firmly fixed on the supporting device during the shooting process, and the angle of rotation of the photographic equipment around the vertical axis can be adjusted by rotation, so that the direction and viewing angle of the shooting picture can be changed, further improving the practicality and shooting effect of the entire photographic supporting device.

[0043] See also Figure 4 In this embodiment, the second connecting seat 31 includes a bottom plate 31a and a side plate 31b arranged on the bottom plate 31a, the bottom plate 31a is connected to the pan / tilt assembly 2 through a screw 33, and the second rotating seat 32 is rotatably connected to the side plate 31b.
