Detailed Description

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings and the detailed description.

The unipod orientation structure as shown in fig. 1 to 6 comprises a base 1 supported on the ground, a base shaft 2 fixedly connected to the base 1, and a connector 3 for connecting a unipod support bar.

The upper end of the base shaft 2 is provided with a ball head 21, and the connector 3 is provided with a ball bowl 31 which can be matched with the ball head 21. Namely, the base shaft 2 and the connector 3 are connected through a spherical hinge, so that the unipod supporting rod can swing in a universal way.

The base shaft 2 is connected with a directional sleeve 4 in a sliding manner along the up-down direction, and the directional sleeve can prop against the connector 3 from bottom to top so as to limit the universal swing of the connector 3.

The orientation sleeve 4 can realize the switching state of the connector 3 between the universal swinging state and the vertical state, and is specifically as follows: the directional sleeve 4 is sleeved on the base shaft 2 and can slide up and down on the base shaft 2, and when the directional sleeve 4 is pressed downwards, the directional sleeve 4 slides downwards to be separated from the connector 3, the connector 3 can swing freely and universally; when the orientation sleeve 4 slides upwards and makes the upper end of the orientation sleeve abut against the lower portion of the connector 3, the orientation sleeve 4 can block the universal swing of the connector 3 and limit the connector 3 to be in an upright state. (of course, if the sleeve 4 does not top the connector 3 too much, the connector 3 may still rotate circumferentially, i.e. horizontally).

A reset structure for driving the directional sleeve 4 to automatically move upwards is arranged between the directional sleeve 4 and the base 1, and a locking structure for locking the directional sleeve 4 and being of a push type is arranged between the directional sleeve 4 and the base shaft 2. Of course, the locking structure may allow the sleeve 4 to be in two positions: one position is where the sleeve 4 slides up against the connector 3 and the other position is where the sleeve 4 slides down to the down position and out of the connector 3.

The reset structure is mainly used for being matched with the locking structure to realize semi-automation, and the reset structure is described in detail later.

Because the locking structure is of a push type, the utility model can be directly stepped on by feet without bending and manual operation, and the operation is simpler. And the push type locking structure can be used for unlocking and locking only by pushing down, so that the push type locking structure is convenient and quick, and saves time and labor.

More specifically, the return structure comprises a return elastic member 5 which is arranged between the orientation sleeve 4 and the base 1 and pushes the orientation sleeve 4 upwards. The return elastic member 5 is preferably a spring.

More specifically, as shown in fig. 2-4, the locking structure includes a locking block 6 fixedly connected to the inner side wall of the directional sleeve 4, and a pull rod 7 rotatably connected to the base shaft 2, a hook 71 is disposed at the upper end of the pull rod 7, a guiding slot 61 for guiding the direction of the hook 71 is disposed on the locking block 6, and the hook 71 can only move circularly in one direction along the guiding slot 61.

The lower end of the guide groove 61 is provided with a start stop position 619, the upper part of the guide groove 61 is provided with a separation block 62 for hanging the hook 71 so as to limit the downward movement of the hook, and the upper end of the separation block 62 is provided with a locking notch 621 for hanging the hook 71. Hook 71 may rest in both the initial rest position 619 and the locking notch 621. I.e. the hook 71 switches between the two positions of the initial rest position 619 and the locking notch 621 each time the sleeve 4 is pressed. The hooks 71 move along the guide grooves 61 only in one direction and circulate between the initial stop position 619 and the locking notch 621.

More specifically, as shown in fig. 2 to 4, the guide groove 61 includes an upper slide section 611 located at the left side of the separation block 62 and extending to the upper left, a lower slide section 612 extending from the upper left end of the upper slide section 611 to the lower right to the locking notch 621, an upper slide section 613 extending from the locking notch 621 to the upper right end, and a lower slide section 614 located at the right side of the separation block 62 and extending downward from the upper right end of the upper slide section 613 to the lower end of the upper slide section 611, and the upper slide section 611, the lower slide section 612, the upper slide section 613 and the lower slide section 614 are sequentially connected;

the bottom surface of the upper sliding section 611 gradually rises from bottom to top in a direction approaching to the base shaft 2, the bottom surface of the lower turning section 612 is lower than the bottom surface of the left upper end of the upper sliding section 611, and a first step surface 615 is arranged between the lower turning section and the upper sliding section; the bottom surface of the upper turning section 613 is lower than the bottom surface of the lower turning section 612, and a second step surface 616 positioned at the left side of the locking notch 621 is arranged between the bottom surface of the upper turning section and the bottom surface of the lower turning section; the bottom surface of the upper right end of the lower sliding section 614 is lower than the bottom surface of the upper turning section 613, and is provided with a third step surface 617, the bottom surface of the lower sliding section 614 gradually rises from top to bottom in the direction close to the base shaft 2, and a fourth step surface 618 is arranged between the bottom surface of the lower end of the lower sliding section 614 and the bottom surface of the lower end of the upper sliding section 611. The above four stepped surfaces mainly function to prevent the hook 71 from reversing.

Referring to fig. 3 and 4, the actual operation procedure of unlocking and locking of the locking structure of the present utility model is as follows:

1) When the orientation sleeve 4 slides upwards and abuts against the connector 3 under the action of the return elastic member 5 (spring), the hook 71 at the upper end of the pull rod 7 is located at the initial stop 619 at the lower end of the upper sliding section 611.

2) When the guide sleeve 4 is stepped down by a foot, the guide sleeve 4 moves down, the hook 71 moves up along the upper slide section 611, and when moving to the upper left end thereof, the hook 71 passes over the first step surface 615 and enters the lower turn section 612.

3) After releasing the foot, the sleeve 4 is moved upwards by the return spring 5, and the hook 71 moves downwards along the lower deflector portion 612 and passes over the second step surface 616 into the upper deflector portion 613. Under the action of the return elastic member 5, the hook 71 is caught at the locking notch 621 at the left lower end of the upper turn section 613. At this time, the sleeve 4 is locked at the lower position, and the joint 3 can swing in all directions in this state.

4) When the sleeve 4 is stepped down again by the foot, the sleeve 4 moves down and the hook 71 moves along the upper steering section 613 toward the upper right corner and passes over the third step surface 617 to enter the slide-down section 614.

5) After the foot is released again, the orientation sleeve 4 moves upward under the action of the return elastic member 5, and the hook 71 moves downward along the lower slide segment 614, finally passes over the fourth step surface 618 and enters the lower portion of the upper slide segment 611, and returns to the original position.

Obviously, the locking structure can realize semi-automation, locking and unlocking can be realized only by stepping on and releasing by foot, and the operation is simple and convenient.

More specifically, as shown in fig. 2 and 3, a connecting screw 8 for connecting the pull rod 7 and the base shaft 2 is provided between them. The lower end of the pull rod 7 is annular, is sleeved on the connecting screw 8, and can swing left and right on the connecting screw 8.

More specifically, as shown in fig. 2 and 5, a circumferential limiting structure for limiting the rotation of the orientation sleeve 4 is arranged between the orientation sleeve 4 and the base 1. The circumferential limiting structure mainly prevents the directional sleeve 4 from rotating relative to the base shaft 2, so that the directional sleeve 4 can only slide up and down on the base shaft 2.

Further, as shown in fig. 2 and 5, the circumferential limit structure includes a limit pin 22 transversely disposed on the base shaft 2 and extending out of the base shaft 2, and a limit slot 41 disposed on an inner sidewall of the directional sleeve 4 and into which an end of the limit pin 22 is inserted and slides up and down.

More specifically, as shown in fig. 1-3 and 5, the outer sidewall of the directional sleeve 4 is provided with a plurality of pedal wings 42 for downward stepping. The pedal wing plate 42 extends outwards from the outer side wall of the directional sleeve 4, so that the pedal is convenient to pedal. The utility model thus allows the orienting sheath 4 to be stepped down directly with the foot, thus unlocking or locking the orienting structure, without having to bend over and operate by hand, which is very convenient and not tiring.

More specifically, the upper end of the orientation sleeve 4 is provided with a first chamfer 43 gradually shrinking from bottom to top, and the lower end of the inner side wall of the connector 3 is provided with a second chamfer 32 capable of being matched with the first chamfer 43. During the upward movement of the sleeve 4, the first chamfer 43 gradually contacts the second chamfer 32 and gradually presses the second chamfer 32 upward, and the sleeve 4 gradually centers the connector 3 against the connector 3 due to the interaction between the inclined surfaces.

More specifically, the base 1 is connected with a plurality of supporting legs 9 to prevent toppling and increase stability.
