[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0028] It should also be noted that the directional terms such as upper, lower, inner, and outer in this embodiment are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0029] First reference Figure 1 and Figure 2 , this embodiment provides a tripod 300, which includes a fixing portion 200 and at least one leg 100 connected to the fixing portion 200. The fixing portion 200 is located above the leg 100 and is used to support a camera or video equipment. In other embodiments, the fixing portion 200 can be used to support the leg 100 to be extended or retracted to a desired length. In this embodiment, there are three legs 100. In other embodiments, the number of legs 100 can also be one (that is, the tripod is a monopod) or more. It can be understood that the fixing portion 200 can also be provided with a locking piece, and when the multiple legs 100 are unfolded to a desired angle, the legs 100 are fixed by the locking piece.

[0030] The leg 100 includes a first section 10, a second section 20 and a third section 30 connected in sequence along the axial direction (the axial direction herein refers to the axial direction of the leg 100) and an operating assembly 60. The operating assembly 60 is used to control the movement of each section.

[0031] Specifically, the first section 10 of the leg 100 is connected to the fixing portion 200. The first section 10 includes two axially extending first rows of tubes 11, and a first base 12 and a second base 13. Among them, the first base 12 is connected to the fixing portion 200. The two first rows of tubes 11 are of the same length, parallel to each other and arranged at intervals in the transverse direction (the transverse direction in this article is perpendicular to the axial direction). The top ends of the two first rows of tubes 11 are respectively fixedly connected to the first base 12, and the bottom ends of the two first rows of tubes 11 are respectively fixedly connected to the second base 13, so that the two first rows of tubes 11 are fixed in the axial direction and the transverse direction through the first base 12 and the second base 13.

[0032] like Figure 1 , 3As shown in Figures 4 and 5, the operating assembly 60 is slidably arranged on the outer periphery of the first section 10, and the operating assembly is also fixedly connected to the second section 20. The operating assembly 60 includes a locking base 61 and an adjustment block 62 and a locking block 63 movably arranged in the locking base 61. The adjustment block 62 is exposed on the locking base 61, and the locking block 63 is located between the adjustment block 62 and the first section 10. When a force perpendicular to the axial direction is applied to the adjustment block 62, the adjustment block 62 can move axially and drive the locking block 63 to approach or move away from the first section 10, thereby locking or releasing the first section 10.

[0033] The locking base 61 is box-shaped and is provided with a first hole 611 and a second hole 612 that penetrate along the axial direction and are arranged at intervals in the transverse direction. The first hole 611 is located in the middle of the locking base 61 and is used for the third section 30 to pass through. There are two second holes 612, which are respectively arranged on the left and right sides of the first hole 611 and are used for the corresponding first row of tubes 11 to pass through. Through the above arrangement, the locking base 61 is slidably arranged on the outer periphery of the two first rows of tubes 11.

[0034] like Figure 7 As shown, the left and right ends of the adjustment block 62 are each provided with a first abutting surface 6221. The first abutting surface 6221 is an inclined surface, and the two first abutting surfaces 6221 are close to each other in the upward direction and relatively far away from each other in the downward direction, so that the adjustment block 62 has a roughly trapezoidal body shape. There are also two locking blocks 63, which are respectively arranged between the adjustment block 62 and the corresponding first row of tubes 11. The left and right sides of the locking block 63 are respectively provided with a curved surface 632 and a second abutting surface 631, wherein the curved surface 632 is used to fit with the outer wall of the corresponding first row of tubes 11, and the second abutting surface 631 is used to cooperate with the first abutting surface 6221. When the adjusting block 62 moves upward along the axial direction, the first abutting surface 6221 of the adjusting block 62 acts on the second abutting surface 631 of the locking block 63, causing the locking block 63 to move laterally, so that the curved surface 632 of the locking block 63 approaches the corresponding first row of tubes 11, and the first row of tubes 11 is pressed against the hole wall of the first channel 611, thereby locking the first row of tubes 11. At this time, the first row of tubes 11 is locked relative to the second section 20. When the adjusting block 62 moves downward along the axial direction, the first abutting surface 6221 of the adjusting block 62 is separated from the second abutting surface 631 of the locking block 63, and the curved surface 632 of the locking block 63 releases the abutment against the first row of tubes 11. At this time, the first row of tubes 11 can move axially relative to the second section 20, and the user can adjust it to a desired position.

[0035] Furthermore, if Figure 5-7As shown, the adjustment block 62 includes a rising slider 622, an ejection slider 625 and a support slider 623 which are sequentially arranged along the axial direction. The support slider 623 is block-shaped, and a support portion 6232 extending vertically upward is provided along one side thereof. The support portion 6232 is also block-shaped, and a fixing hole 6231 is provided which penetrates along its thickness direction. The ejection slider 625 is provided with an ejection portion 6252 extending from the fixing hole 6231, and the ejection portion 6252 passes through the fixing hole 6231 and extends out of the locking base 61 to operate it. The extension direction of the ejection portion 6252 is perpendicular to both the horizontal direction and the axial direction. Preferably, the ejection portion 6252 passes through the back side of the locking base 61, that is, the side of the locking base 61 facing away from the user, so as to maintain the overall aesthetics and facilitate hidden operation. The ejection slider 625 has an inclined fifth abutment surface 6251, and the fifth abutment surface 6251 faces the rising slider 622. The rising slider 622 is also block-shaped, and a receiving cavity 6222 is concavely arranged at the bottom end thereof facing the ejection slider 625, and the first abutting surfaces 6221 are respectively arranged at the left and right sides of the top end thereof facing away from the ejection slider 625. When the ejection portion 6252 is moved along its own extension direction, the ejection slider 625 moves on the supporting slider 623, and through the interaction of its fifth abutting surface 6251 with the cavity wall of the receiving cavity 6222 of the rising slider 622, the rising slider 622 is driven to move axially upward or downward, thereby acting on the locking block 63, and locking or releasing the first row of tubes 11.

[0036] Preferably, the ejection portion 6252 is an adjustment screw threadedly connected to the ejection slider 625. In this embodiment, it is configured that: when the adjustment screw is rotated clockwise, the ejection slider 625 pushes the ascending slider upward to make it move upward, thereby driving the locking block 63 and the locking ring 81 to respectively lock the first row of tubes 10 and the third row of tubes 30. Conversely, when the adjustment screw is rotated counterclockwise, the locking block 63 releases the contact with the first row of tubes 11, and the locking ring 81 loosens the third row of tubes 30.

[0037] In this embodiment, the operating assembly 60 is disposed on the second section 20. When the legs 100 are unfolded, the handle 43 of the operating assembly 60 is close to the user's hand, so that the user can operate the handle 43 without bending over. This position setting is more ergonomic, labor-saving and convenient. It is understandable that in other embodiments, the operating assembly 60 can also be disposed in other positions.

[0038] Reference again Figure 1 and Figure 3, the second section 20 is connected to the first section 10. The second section 20 includes a third base 22 and two axially extending second rows of tubes 21. The two second rows of tubes 21 have the same length, are parallel to each other and are arranged in a lateral interval. The top ends of the two second rows of tubes 21 pass through the second base 13 respectively and are fixedly connected to the locking base 61. The bottom ends of the two second rows of tubes 21 are fixedly connected to the third base 22 respectively, so that the two second rows of tubes 21 are fixed in the lateral direction. Again, refer to Figure 6 , the locking base 61 is provided with a third hole 613 that penetrates axially. There are two third holes 613, which are respectively arranged between the first hole 611 and the corresponding second hole 612, and are used to fix the second row of tubes 21. The second base 13 is provided with a fourth hole 131 that penetrates axially. There are also two fourth holes 131, which are axially aligned and connected with the corresponding third holes 613. The top ends of the two second rows of tubes 21 slide through the corresponding fourth holes 131, and are then respectively fixed in the two third holes 613 of the locking base 61, so that the locking base 61 can be moved axially, thereby driving the second row of tubes 21 to move axially on the first section 10, and realizing the expansion and contraction of the first section 10 and the second section 20. In this embodiment, the first row of tubes 11 and the second row of tubes 21 are arranged at intervals in the transverse direction, which facilitates the expansion and contraction of the first section 10 and the second section 20. In other embodiments, the first row of tubes 11 and the second row of tubes 21 can also be mutually sleeved.

[0039] Combined with reference Figure 8 , the third section 30 includes a third row of tubes 31. In this embodiment, the third row of tubes 31 is slidably connected to the second section 20 through the third base 22. The adjustment block 62 is provided with an axially penetrating through hole 621 for the third row of tubes 30 to pass through. The third base 22 is provided with an axially penetrating fifth hole 221 for the third row of tubes 31 to slide through. The fifth hole 221 is located between the two second rows of tubes 21, and the sleeve section 811 of the locking ring 81 is provided in the fifth hole 221 and sleeved on the outer periphery of the third row of tubes 31. When the locking ring 81 releases the clamping of the third row of tubes 31, the third row of tubes 31 can move axially to between the two second rows of tubes 21, thereby achieving the overlap of the third section 30 with the second section 20. When the third row of tubes 31 moves axially to between the second row of tubes 21, and then the locking base 61 of the operating assembly 60 is axially moved, the third section 30, the second section 20 and the first section 10 can be overlapped, thereby achieving the contraction of the entire leg 100. Optionally, a support seat 32 is further provided at the bottom end of the third section 30, and a foot nail can be provided at the bottom of the support seat 32 to strengthen the fixing effect with the ground.

[0040] Preferably, the leg 100 of this embodiment further includes a central axis 23 disposed in the second section 20. The central axis 23 is a hollow rod extending axially. The second base 12 is provided with a sixth hole 132 axially penetrating therethrough, and the sixth hole 132 is axially aligned with and connected to the first hole 611 of the locking base 61. The upper end of the central axis 23 is fixed in the sixth hole 132, and the lower end is fixed in the fifth hole 221. When the third section 30 and the second section 20 are contracted (overlapped), the third row of tubes 31 can move axially to the inner wall of the central axis 23. The provision of the central axis 23 further strengthens the stability of the support of the second section 20.

[0041] The transmission assembly 70 is connected to the adjustment block 62, and is used to transmit the axial action of the adjustment block 62 to the third section 30. In this embodiment, the second row of tubes 21 is a hollow rod, and the transmission assembly 70 axially passes through the inner wall of the second row of tubes 21. Specifically, the transmission assembly 70 is a cable with a certain rigidity. The adjustment block 62 is provided with an axial through hole 624 for the cable to pass through. The cable is in an inverted U shape, one end of which is connected to the third base 22, and the other end passes through the corresponding inner wall of the second row of tubes 21, the through hole 624 and the inner wall of another second row of tubes 21 in sequence, and is connected to the third base 22 again. The cable structure is slender and easy to store, and it passes through the adjustment block as a whole and is accommodated in the inner walls of the two second rows of tubes, so that the overall structure is simple and the transmission efficiency is high. In other embodiments, the transmission assembly 70 can also use other structures to transmit the force, such as wire ropes, steel bars or connecting rods.

[0042] The rising slider 622 and the supporting slider 623 jointly define an axial through hole 624 and a through hole 621. The through hole 621 is used for the third row of tubes 30 to pass through. There are two axial through holes 624 arranged at intervals. A groove 6223 for accommodating a cable is provided on the top surface of the rising slider 622. The groove 6223 is arc-shaped, and two axial through holes 624 are located at both ends of the groove 6223. The closed end of the U-shaped cable is located in the groove 6223, and its two free ends respectively pass through the axial through holes 624, and pass through the corresponding inner walls of the second row of tubes 21, and then are fixedly connected to the third base 22. When the ejection portion 6252 is pushed and pulled to move along its own extension direction, the ejection slider 625 moves on the supporting slider 623, and through its fifth abutment surface 6251 acts on the cavity wall of the accommodating cavity 6222 of the rising slider 622, drives the rising slider 622 to move axially upward or downward, thereby acting on the locking block 63 and the cable 70 at the same time, thereby realizing synchronous adjustment of the first section 10 and the third section 30.

[0043] The locking assembly 80 is disposed in the third base 22 and is used to lock or release the third section 30. Figure 8 and Fig. 9As shown, the locking assembly 80 includes a locking ring 81 and a locking member 82. In this embodiment, the locking member 82 is block-shaped and connected to one end of the cable. The locking member 82 is axially arranged corresponding to one of the second row tubes 21, and is provided with a locking cavity 821 facing the other second row tube 21. The locking cavity 821 is defined by a cavity wall. The cavity wall has two third abutment surfaces 8221 symmetrically arranged along its axial direction. The locking ring 81 is Ω-shaped, including a semi-annular sleeve section 811, and two free sections 812 connected to the sleeve section 811. The sleeve section 811 is sleeved on the outer wall of the third section 30. The two free ends are close to and located in the locking cavity 821. The two free ends of the locking ring 81 are respectively provided with fourth abutment surfaces 8121 that cooperate with the third abutment surfaces 8221. The third abutting surface 8221 is axially located below the corresponding fourth abutting surface 8121, so that when the cable pulls the locking member 82 to move upward in the axial direction, the third abutting surface 8221 of the locking member 82 pushes upward against the fourth abutting surface 8121 of the locking ring 81, so that the two free ends are close to each other, thereby achieving the clamping of the locking ring 81 on the third section 30. When the tension on the cable is eliminated, the locking block 63 returns to its original position, thereby releasing the clamping of the third section 30.

[0044] Preferably, the locking member 82 may further include an elastic member 83. The elastic member 83 is connected to one end of the cable and the locking member 82, respectively. When the cable is subjected to an axial tension of the adjustment block 62, the cable pulls the locking member 82 to move axially through the elastic member 83, and the elastic member 83 is deformed. When the tension on the cable is eliminated, the elastic member 83 will restore the deformation. At the same time, the locking member 82 can return to its original position driven by the elastic member 83. The elastic member 83 of this embodiment is a spring.

[0045] Further preferably, the locking member 82 may further include a cable adjuster 84 for adjusting the tightness of the cable. Figure 8 As shown, a seventh hole 222 and an eighth hole 223 are respectively provided on both sides of the fifth hole 221 of the third base 22, which are respectively used to place the locking member 82 and the cable adjuster 84. The cable adjuster 84 is provided with an adjustment knob 841 exposed on the third base 22, and the adjustment knob 841 is connected to one end of the cable. By rotating the adjustment knob 841, the tightness of the cable can be adjusted, thereby adjusting the tightness of the locking ring 81. This arrangement enables the third section 30 to be adjusted separately, so as to further compensate for the lack of adjustment accuracy of the locking assembly 80.

[0046] In a preferred embodiment, the operating component 60 can also be additionally connected to other transmission components to generate axial movement, such as a pull rod or a wrench.

[0047] The above description is only a preferred specific implementation manner of the present invention. The protection scope of the present invention is not limited to the embodiments listed above. Any simple change or equivalent replacement of the technical solution that can be obviously obtained by any technician familiar with the technical field within the technical scope disclosed in the present invention falls within the protection scope of the present invention.
