[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0040] See also Figure 1-9The photographic stand that is easy to open in one embodiment of the present invention includes a telescopic rod assembly and a handle assembly 40. The telescopic rod assembly includes a telescopic rod body 10 and a tailstock 20 fixed to the tail end of the telescopic rod body 10. The telescopic rod body 10 has a telescopic design to adapt to different usage scenarios and height requirements. The telescopic rod body 10 is made of a high-strength lightweight material (such as aluminum) to ensure the stability and portability of the stand. The tailstock 20 is provided with at least three positioning recesses 212c arranged in a circumferential direction. These positioning recesses 212c are used to cooperate with the positioning protrusions 421 on the handle assembly 40 to achieve a stable locking of the legs 42.

[0041] The handle assembly 40 includes a mounting seat 41 and three legs 42, wherein the mounting seat 41 is sleeved on the telescopic rod body 10. The upper ends of the three legs 42 are pivotally connected to the mounting seat 41, and the lower ends of the three legs 42 are provided with positioning protrusions 421 that match the positioning recesses 212c. The legs 42 can be unfolded to form a stable triangular structure to increase the stability of the photographic support. As an alternative, the number of the legs 42 can also be more than three.

[0042] The tailstock 20 includes a tailstock body 21 and a button member 22. The tailstock body 21 is fixed to the tail end of the telescopic rod body 10. The bottom surface of the tailstock body 21 is provided with at least three positioning recesses 212c. The button member 22 is mounted on the tailstock body 21 and can be extended and retracted along the axis of the telescopic rod body 10. The button member 22 is provided with at least three driving parts 221 arranged along the circumferential direction. When the button member 22 moves to the retracted position, the at least three driving parts 221 apply a thrust to the lower ends of the three legs 42, so that the positioning protrusion 421 is separated from the positioning recess 212c.

[0043] As an alternative, to meet different manufacturing and use requirements, the positions of the positioning recess 212c and the positioning protrusion 421 can be interchanged. That is, in some embodiments, the positioning recess is provided on the lower end of the support leg 42, and the positioning protrusion is provided on the bottom surface of the tailstock body 21.

[0044] The tailstock of the above-mentioned easy-to-open photographic stand adopts the design of the button member 22 and the driving part 221. The user only needs to press the button member 22 to release all the legs 42 at the same time, without having to pry open the legs 42 one by one, which greatly simplifies the operation steps and improves the convenience of use. In addition, the positioning protrusion 421 is separated from the positioning recess 212c by applying a thrust through the button member 22 and the driving part 221, avoiding the situation where the user needs to use a lot of force to pry open the legs 42. This labor-saving design not only reduces the difficulty of operation, but also reduces the risk of product damage caused by excessive force.

[0045] As an example, the tailstock body 21 includes a base 211 and a bottom cover 212, wherein the base 211 is fixed to the tail end of the telescopic rod body 10, and the bottom cover 212 is covered on the base 211. The tailstock body 21 adopts a split structure, which is convenient for processing and assembly. In this embodiment, the base 211 has a cylindrical outer cylinder portion 211a and a fixing portion 211b located in the outer cylinder portion 211a, and a mounting hole 211c is provided at the center of the fixing portion 211b. The bottom cover 212 includes a cover body 212a and a positioning seat 212b located on the top surface of the cover body 212a, and the positioning seat 212b of the bottom cover 212 is inserted into the mounting hole 211c of the base 211. A first fixing hole 11 is provided at the lower end of the telescopic rod body 10, a second fixing hole 211d is provided on the fixing portion 211b corresponding to the first fixing hole 11, a third fixing hole 212e is provided on the positioning seat 212b corresponding to the first fixing hole 11, and a fixing pin (not shown in the figure) passes through the first fixing hole 11, the second fixing hole 211d and the third fixing hole 212e to fix the base 211 and the bottom cover 212 to the lower end of the telescopic rod body 10.

[0046] In one embodiment, each of the driving parts 221 is provided with a first inclined surface 221a, and the inner side surface of the lower end of the support leg 42 is provided with a second inclined surface 421 that matches the first inclined surface 221a; when the button member 22 moves to the retracted position, the first inclined surface 221a and the second inclined surface 421 slide relative to each other to apply a thrust to the lower end of the support leg 42. The design of the inclined surface allows the first inclined surface 221a to slide along the second inclined surface 421 when the button member 22 moves, thereby applying an outward thrust to the lower end of the support leg 42. The action of this force releases the support leg 42 from the positioning recess 212c, thereby causing the support leg 42 to expand outward. The interaction of the inclined surfaces provides a stable and reliable force transmission mechanism to ensure the stability and safety of the bracket during use.

[0047] In one embodiment, each of the driving parts 221 has a first inclined surface 221a on two side surfaces along the circumferential direction, and each of the lower ends of the supporting legs 42 has a second inclined surface 421 on the inner side surfaces at both ends in the circumferential direction; when all the supporting legs 42 are in a closed state, the two first inclined surfaces 221a on each of the driving parts 221 are in contact with the corresponding second inclined surfaces 421 at the lower ends of two adjacent supporting legs 42 in the circumferential direction, respectively. In this design, since each driving part 221 can contact the inclined surfaces of two supporting legs 42 at the same time, each supporting leg 42 is evenly stressed when it is unfolded, and the operation is smooth.

[0048] In one embodiment, the inner side surfaces of the lower ends of all the legs 42 enclose a triangular accommodation space, the button member 22 is a triangle matching the accommodation space, and the driving portion 221 is located at the three vertices of the triangle. In this design, when the button member 22 is operated, the driving portion 221 at each vertex of the triangle directly pushes the lower end of the corresponding leg 42 through the interaction of the inclined surfaces, thereby realizing the rapid deployment or storage of the leg 42. This direct action reduces the energy loss in the mechanical transmission and improves the response speed.

[0049] In one embodiment, the outer side surface of the button member 22 between two adjacent driving parts 221 in the circumferential direction is in an inwardly concave shape relative to the corresponding side surface of the button member 22. This design prevents other side surfaces of the button member 22 from affecting the inclined surface, thereby improving reliability.

[0050] In one embodiment, the tailstock further comprises an elastic component, and the elastic component is arranged between the tailstock body 21 and the button member 22. The elastic component can be a spring, a rubber pad, or other applicable elastic materials, and its main function is to provide the necessary return force to support the button member 22 to automatically return to the original position after being pressed. In this embodiment, the elastic component is a spring 23, and a stepped mounting column 222 is provided at the center of the top surface of the button member 22. The spring 23 is sleeved on the thin section of the mounting column 222, and one end of the spring 23 abuts against the end surface between the thin section and the thick section of the mounting column 222, and the other end abuts against the bottom surface of the bottom cover 212.

[0051] In one embodiment, one of the button member 22 and the tailstock body 21 is provided with a guide protrusion extending in the axial direction, and the other is provided with a guide recess matched with the guide protrusion. The movement of the button member 22 is guided by the cooperation of the guide protrusion and the guide recess, so that the button member 22 moves smoothly. In this embodiment, the guide protrusion is a plurality of guide columns 223 arranged on the top surface of the button member 22, and the guide recess is a plurality of axially extending notches 211e arranged on the outer cylinder 211a of the base 211.

[0052] In one embodiment, the button member 22 is provided with a buckle 224, the tailstock body 21 is provided with a buckle hole 212f, and the hook portion of the buckle 224 passes through the buckle hole 212f, so as to connect the button member 22 and the tailstock body 21 together; and / or the button member 22 and the tailstock body 21 are connected by a screw 24. In this embodiment, the top surface of the button member 22 is provided with a plurality of buckles 224 extending in the axial direction, the cover body 212a of the bottom cover 212 is correspondingly provided with a plurality of buckle holes 212f, the hook portions of the plurality of buckles 224 respectively pass through the plurality of buckle holes 212f, a through hole (not shown in the figure) is provided at the center of the mounting column 222, and a screw hole is provided on the cover body 212a of the bottom cover 212, and the head end of the screw 24 passes through the through hole and is screwed into the screw hole.

[0053] In one embodiment, the mounting seat 41 can slide along the telescopic rod and further comprises at least three connecting rods 30 , wherein the first ends 31 of the at least three connecting rods 30 are respectively hinged to at least three supporting legs 42 , and the second ends 32 are respectively hinged to the tailstock body 21 .

[0054] In one embodiment, a rotating shaft is disposed at the second end 32 of at least three connecting rods 30 , and when the bottom cover 212 is covered on the base 211 , an axial hole matching with the rotating shaft is formed therebetween.

[0055] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
