Tripod capable of being erected quickly

Abstract

A tripod capable of being erected rapidly comprises an angle swing assembly, a ball arranged in the angle swing assembly, a guide rod connected with the ball, a lifting operation longitudinal component moving up and down along the guide rod, and a rebound mechanism connected with the lifting operation longitudinal component in an abutting mode. The lifting operation longitudinal component is switched between a locking position entering the opening cavity of the angle swinging group and an unlocking position far away from the opening cavity of the angle swinging group by virtue of the springback mechanism; and the lifting operation longitudinal component is driven to enable the rotary ratchet groove drum to rotate, so that the lifting operation longitudinal component enables the rotary ratchet groove drum to start to steer by means of the elastic component when the guide abutting groove tongue device encounters a rotation stopping position upwards, and the lifting operation longitudinal component is rebounded to the locking position when no barrier exists in the upward direction. The tripod is simple in structure, higher in stability and less in external interference in operation, and a rebound locking mechanism allows the tripod to rapidly rebound and be locked at a required position after the angle or height of the tripod is adjusted.

[0029] Combined with the drawings of the specification, the specific embodiments of the present invention are further described below to make the technical solutions and their beneficial effects of the present invention clearer and more definite; and it is intended to explain the present invention and should not be construed as a limitation to the present invention.

[0030] Referring to Figure 1-7 As shown, the preferred embodiment of the present invention provides a tripod that can be quickly erected vertically, which includes an angle swing assembly 1, a sphere 2 disposed within the angle swing assembly 1, a guide rod 3 connected to the sphere 2, a lifting operation longitudinal member 4 that moves up and down along the guide rod 3, and a rebound mechanism 5 that connects and abuts against the lifting operation longitudinal member 4, and the rebound mechanism 5 is used to convert the lifting operation longitudinal member 4 between a locked position where it enters the opening 11 of the angle swing assembly and an unlocked position away from the opening 10 of the angle swing assembly; the rebound mechanism 5 includes a tripod main body 51, a rotating ratchet groove cylinder 52 disposed within the tripod main body 51, a guide abutting groove tongue device 6 connected to the lifting operation longitudinal member 4, and an elastic member 7 that holds up the lifting operation longitudinal member 4; the tripod main body 51 is provided with an installation portion 511 for docking the guide rod 3, and a matching structure 512 is formed within the cavity of the tripod main body 51 to limit the up and down movement of the lifting operation longitudinal member 4 therein; the guide abutting groove tongue device 6 is disposed at the installation position 41 of the lifting operation longitudinal member, and the inward extending portion of the guide abutting groove tongue device 6 enters to cooperate with the rotating ratchet groove cylinder 52, driving the lifting operation longitudinal member 4 to rotate the rotating ratchet groove cylinder 52, so that the lifting operation longitudinal member 4 starts to turn when the guide abutting groove tongue device 6 encounters a stop position 521 upward by means of the elastic member 7, and when there is no obstacle upward, the lifting operation longitudinal member 4 rebounds to the locked position. The installation position 41 can be an installation hole or an installation groove. The elastic member 7 can be a helical spring.

[0031] Among them, a plurality of connected guide ratchet groove groups are formed on the outer wall of the rotating ratchet groove cylinder 52, and the guide ratchet groove group includes a vertical groove 522, a first arc groove section 523 disposed at the lower part of the vertical groove 522 and communicating with the vertical groove 522, a stop section groove 524 communicating with the first arc section groove 523, and a second arc groove section 525 connecting the stop section groove 524.

[0032] In this embodiment, the matching structure 512 can be a protrusion or a groove, and a matching member is formed on the outer side wall of the lifting operation longitudinal member corresponding to the protrusion or the groove. Specifically, it is a guide rail structure, but it does not exclude an assembly transmission structure, such as a slide rail structure, a meshing structure, etc.

[0033] The angle swing assembly 1 includes a cylinder 11, an inner support cylinder 12 arranged inside the cylinder 11, a spherical support cup 13 and a lower cylinder 14 connected to the inner support cylinder 13. The cylinder is provided with a protective sleeve 15, and the inner support cylinder 12 has an embedded boss 121.

[0034] The lifting operation longitudinal member 4 is provided with at least one anti-skid footrest extension 42. The guide tongue device 6 comprises a jacket 61, a telescopic column 62 disposed in the jacket 61, a spring 63 for holding the telescopic column 62, and a bottom cover 64 for limiting the spring 63 in the inner cavity of the jacket 61 and fitting to the bottom of the jacket.

[0035] The stop position 512 can be a non-return transition recess, which is arranged at the lower part of the vertical groove 522. Of course, the number of stop positions 512 can be set to multiple, according to different operation requirements; the non-return steering is achieved by virtue of the transition recess being deeper or a through hole than the vertical groove 522. When the telescopic column 62 reaches this position, it extends out and is clamped. Under the elastic force of the elastic component 7, the rotating ratchet groove cylinder 52 can only rotate the telescopic column 62 to enter the first arc-shaped groove section 523.

[0036] The mounting portion 511 is a concentric bolt located in the center of the cavity of the tripod body 51 ; the guide rod 3 is screwed on the mounting portion 511 and fixed.

[0037] The lifting operation longitudinal member 4 has a convex neck ring 43, and the convex neck ring 43 has a side wall that is narrow at the top and wide at the bottom, and an introduction slope 433 is formed between the side wall 431 and the top wall 432, so that it is very easy to introduce the angle swing assembly opening cavity 10 and form a gradually tight matching effect.

[0038] When in use, when unlocking is required, the non-slip foot pedal extension 42 moves the lifting operation longitudinal member 4 downward, and the guide tongue device 6 moves downward from the vertical groove 522 to the rotation stop position 512 for non-return steering. Under the elastic force of the elastic member 7, the ratchet groove cylinder 52 can only be rotated to make the telescopic column 62 enter the first arc groove section 523 and then enter the stop groove 524. Then, the telescopic column 62 is stepped on again, and then the telescopic column 62 is separated from the second arc groove section 525 of the stop groove 524 and then enters the adjacent vertical groove 522 to return to the locking position to form a fast upright state. The utility model has a simple structure, higher stability and less external interference in operation. The rebound locking mechanism allows the tripod to quickly rebound and lock in the desired position after adjusting the angle or height, without manual clamping or screwing again, saving time and operation steps; it is particularly suitable for scenes where the shooting angle and height need to be quickly adjusted, such as outdoor snapshots or sports photography. It effectively reduces shaking caused by improper manual adjustment or loose locking, improves shooting quality and makes the tripod more compact and lightweight when adjusting the angle and storing.
