As shown in fig. 1 to 4, an embodiment of the present application discloses a tripod, including a fixing base 100; three leg assemblies 200 respectively hinged to the fixing base 100 for supporting the fixing base 100; a main rod 300 passing through the fixing base 100 and movably connected with the fixing base 100; the linkage mechanism 400 comprises a movable ring 410 and three linkage rods 420, wherein the movable ring 410 is sleeved on the main rod 300 and is in sliding connection with the main rod 300, one end of each linkage rod 420 is hinged to the movable ring 410, and the other end of each linkage rod 420 corresponds to one of the support leg assemblies 200 and is hinged to the support leg assembly 200; and a locking structure 500, the locking structure 500 being respectively provided on the main pole 300 and the leg assembly 200 when the tripod is folded, the main pole 300 being connected with the leg assembly 200 through the locking structure 500, the locking structure 500 being used for locking the main pole 300 with at least one of the leg assemblies 200.

The tripod can be usually folded or folded when not in use, and the locking structure 500 is arranged at the bottoms of the main rod 300 and the leg assemblies 200, so that the three leg assemblies are connected through the linkage mechanism 400, and the locking structure 500 only needs to lock at least one leg assembly, so that the three leg assemblies can be fixed simultaneously to prevent the leg assemblies from being opened accidentally, and the tripod is simple in structure and good in stability.

Specifically, as shown in fig. 2, in this embodiment, the locking structure 500 is respectively disposed at one end of the main rod 300 and the leg assembly 200, which is far away from the fixing base 100, that is, at a position closest to the ground, the locking structure 500 includes a hook 510 and a slot 520, the hook 510 is disposed on the main rod 300, the slot 520 is disposed on the leg assembly 200, the hook 510 is connected with the slot 520 in a matching manner, the hook 510 on the main rod 300 is matched with the slot 520 on the leg assembly to achieve locking, so that the leg assembly is not easy to open, and moreover, the locking position is far away from the fixing base 100, and the arm of force is relatively long, so that the tension applied to the corresponding locking part is minimal, thereby further improving stability, and making the locking part not easy to open; of course, the positions of the hooks 510 and the slots 520 can be changed, for example, the hooks 510 are disposed on the leg assembly 200, and the slots 520 are disposed on the main rod 300.

More specifically, as shown in fig. 2 and 3, a truncated cone-shaped limiting seat 600 is disposed at one end of the main rod 300 away from the fixing seat 100, the limiting seat 600 is fixedly connected to an end of the main rod 300, the movable ring 410 is located between the fixing seat 100 and the limiting seat 600, the movable ring 410 can only slide between the fixing seat 100 and the limiting seat 600, the limiting seat 600 includes a first cylinder 610 and a second cylinder 620 that are stacked on each other, a diameter of the first cylinder 610 is smaller than a diameter of the second cylinder 620, the first cylinder 610 is fixedly connected to the main rod 300, an outer diameter of a diameter of the second cylinder 620 is not smaller than an inner diameter of the movable ring 410, and the hooks 510 are disposed on the second cylinder 620 and located on a side surface of a cylindrical surface. Spacing seat 600 injects the bottom fixed connection of mobile jib 300 through first cylinder 610, when stabilizer blade assembly 200 is opened by drawing in, gangbar 420 drives activity ring 410 from last down sliding on mobile jib 300, spacing seat 600's second cylinder 620 has a limiting displacement to activity ring 410, prevent activity ring 410 from the roll-off of mobile jib 300 bottom, and pothook 510 sets up on the side of second cylinder 620, activity ring 410 also can't direct contact pothook 510 prevent to cause the striking harm to it at the slip in-process, the improvement durability.

According to the position of the limiting seat 600, correspondingly, as shown in fig. 2 and 4, the supporting leg assembly 200 includes a supporting leg 210 and a hinge seat 220, the hinge seat 220 is disposed at one end of the supporting leg 210 away from the fixing seat 100 and is hinged to the linkage rod 420, and the locking groove 520 is disposed on the hinge seat 220; articulated seat 220 is fixed to be set up in the bottom of stabilizer blade 210, and draw-in groove 520 corresponds the setting and faces the position of mobile jib 300 at articulated seat 220, and when stabilizer blade 210 draws in to mobile jib 300, make things convenient for pothook 510 and draw-in groove 520 direct counterpoint cooperation, with its locking, moreover, articulated seat 220 all is relatively fixed with spacing seat 600's position, also more fast and counterpoint the accuracy when counterpointing the locking.

Further, in the present embodiment, as shown in fig. 3, the number of the locking structures 500 is three, and each of the locking structures 500 corresponds to one of the leg assemblies 200; correspondingly, on the same limiting seat 600, three groups of hooks 510 are arranged, each group of hooks 510 corresponds to one clamping groove 520 on one supporting leg 210, each group of hooks 510 is two, the hooks 510 are horizontally arranged on the side surface of the second cylinder 620, the hooks 510 are in a J shape, the bending directions of the two hooks 510 in each group of hooks 510 are mutually deviated, the clamping grooves 520 are correspondingly matched with the hooks 510, and the hooks 510 are embedded into the clamping grooves 520 by extrusion and are in locking fit with the clamping grooves 520; the two hooks 510 correspond to one slot 520, and the hooks 510 are not easy to fall off after being clamped with the slots 520 in the horizontal direction.

Furthermore, as shown in fig. 4, the opening of the clamping groove 520 is an inclined surface, the hooks 510 are embedded into the clamping groove 520 through extrusion, and the opening of the clamping groove 520 is provided with the inclined surface, so that the two hooks 510 are more easily elastically deformed inwards through the guiding effect of the inclined surface, and are conveniently clamped by entering the clamping groove 520.

In this embodiment, as shown in fig. 2 and 4, for the convenience of folding and unfolding, the bottom of the clamping groove 520 corresponding to the vertical direction is hollowed, the limiting seat 600 is detachably connected to the main rod 300, when the supporting legs 210 need to be folded, the movable ring 410 drives the linkage rod 420 to enable the supporting legs 210 to approach the main rod 300, and the clamping hook 510 on the limiting seat 600 of the main rod 300 is matched with the clamping groove 520 on the hinge seat 220, so as to ensure that the whole tripod can not be easily unfolded after being folded; when needing to open, because spacing seat 600 can be dismantled, take out the mobile jib 300 with spacing seat 600 vertical direction, make its pothook 510 also break away from in draw-in groove 520, can the unblock open stabilizer blade 210 once more, it can to install spacing seat 600 again afterwards.

Of course, the spacing base 600 and the main rod 300 may not be detached, and the spacing base 600 may be flexibly connected to the main rod 300 in a telescopic manner, so as to achieve the effect of convenient opening.

As shown in fig. 5, the tripod further includes a tripod head 700, the tripod head 700 is disposed above the fixed base 100 and connected to the main rod 300, and the length of the main rod 300 between the tripod head 700 and the fixed base 100 is adjustable; the user needs to raise the camera and directly extend the main rod 300 upwards.

The foregoing is a more detailed description of the present application in connection with specific alternative embodiments, and the present application is not intended to be limited to the specific embodiments shown. For those skilled in the art to which the present application pertains, several simple deductions or substitutions may be made without departing from the concept of the present application, and all should be considered as belonging to the protection scope of the present application.
