[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown:

[0024] Embodiment 1: The utility model provides a human flow counting device, comprising: a folding frame mechanism 1, including a folding frame assembly 11, a clamping assembly 12 that is damped and rotatably embedded on the folding frame assembly 11; a camera 2 that is embedded on the clamping assembly 12; a clamping mechanism 3, including a C-shaped bracket assembly 31 connected to the folding frame assembly 11, and a group of clamping rod assemblies 32 that are rotatably embedded on the C-shaped bracket assembly 31;

[0025] Among them, the C-shaped bracket component 31 is embedded in the edge of the table, and can be fixed on the table after rotating a group of clamping rod components 32. The camera 2 can be clamped and fixed by the clamping component 12. The rotating folding frame component 11 can adjust the shooting direction of the camera 2. The pitch angle of the camera 2 can be adjusted by rotating the clamping component 12, so as to capture the flow of people more comprehensively.

[0026] Specifically, the folding frame assembly 11 includes a bracket 111, a bracket 2 112 and a limiting rod 113. The outer side of the upper end of the bracket 111 is fixedly connected with an axle rod 114, the upper end of the bracket 2 112 is fixedly connected with an axle rod 2 115, the bottom of the outer side of the bracket 2 112 is fixedly connected with a limiting ring 116 and a limiting ring 2 117, the outer side of the limiting rod 113 is fixedly connected with a clamping ring 118, and the outer side of the limiting rod 113 is sleeved with a spring 119.

[0027] Specifically, the bracket 112 is rotatably embedded in the shaft 114, the limit rod 113 is slidably embedded in the limit ring 116 and the limit ring 117, the snap ring 118 and the spring 119 are located between the limit ring 116 and the limit ring 117, and the spring 119 can drive the snap ring 118 to drive the limit rod 113 to embed into the upper end of the bracket 111.

[0028] As can be seen from the above, after use, pulling the limit rod 113 upwards can cause the retaining ring 118 to drive the spring 119 to be compressed on the limit ring 116, and at the same time the limit rod 113 is separated from the upper end of the bracket 111. At this time, the staff can rotate the bracket 112 around the shaft 114, so that the bracket 112 is against the bracket 111, thereby avoiding taking up more space.

[0029] Embodiment 2: This embodiment is basically the same as the previous embodiment, with the difference that the clamping assembly 12 includes a fixed clamping plate 121 and a movable clamping plate 122, one end of the fixed clamping plate 121 is fixedly connected to a limited axis frame 123, a movable groove 124 is also provided inside the fixed clamping plate 121, one end of the movable clamping plate 122 is fixedly connected to a group of guide rods 125, the ends of the guide rods 125 are fixedly connected to a ring 126, the outer side of the guide rods 125 is located in the movable groove 124 and is also sleeved with a spring 127, and the camera 2 is embedded in the fixed clamping plate 121 and the movable clamping plate 122.

[0031] Specifically, the threaded rod 321 is rotatably embedded in the threaded hole 313 , and the bottom end of the bracket 111 is limitedly rotatably embedded in the T-shaped frame 312 .

[0032] As can be seen from the above, a group of C-shaped brackets 311 are embedded in the edge of the table, and rotating the handle 323 can make the threaded rod 321 rotate in the threaded hole 313, and at the same time, the positioning clamping ring 322 moves to be fixed on the table, thereby playing a fixing role. The bottom end of the bracket 111 is limited and rotated and embedded in the T-shaped bracket 312, which can facilitate the staff to adjust the shooting direction of the camera 2; pulling the movable splint 122 can make a group of guide rods 125 drive the ring 126 to move in the movable groove 124, and at the same time, the spring 127 is compressed in the movable groove 124, and the camera 2 is placed on the fixed splint 121. After loosening the movable splint 122, the spring 127 resets to fix the camera 2.
