Description

Rotary locking base

Technical Field

The present invention relates to a rotary locking base, and more particularly to a rotary locking base which can rotate a stand and a base relative to a turntable at the same time and can be stably and precisely positioned.

Background

At present, a common planar electronic device such as a tablet computer or an AIO computer is supported by a supporting stand, so that the planar electronic device stands, and a base of the supporting stand is pivoted with a pivoting mechanism, so that the display device can be horizontally rotated and positioned, and the tablet computer is positioned at different angles, thereby facilitating the touch operation of a user. The pivot mechanism mainly comprises a central bearing group and a plurality of limiting screws on the periphery, and the limiting screws can slide in the set arc-shaped grooves, so that when the display is stressed, the display can rotate relative to the base because of the preset sliding path of the limiting screws and the central bearing group. However, the above-mentioned supporting device only allows the display to have a basic pivoting function, but does not consider the different requirements of displays with different specifications and sizes, so that when the display with other sizes and weights is mounted, the operation is not smooth.

Therefore, for example, taiwan patent No. M514534U discloses a solution for a rotatable supporting device, which mainly includes a bracket, a chassis, and an adjustable structure connected between the bracket and the chassis, wherein the adjustable structure is axially matched with a plurality of washers, and an external force required for driving the bracket and the adjustable structure to rotate relative to the chassis is adjusted by using an interference degree of an engagement structure between the washers. Therefore, a user can select a proper section according to the specifications of the screen such as size, weight and the like, even the operation habits such as force application position and the like. The friction force in the structure is changed through the engagement and interference degree in the adjustable structure, and the force applied to the display by a user is transmitted to the rotating structure and overcomes the friction force, so that the display can be driven to rotate on the horizontal plane to adjust the angle; and in the process of operation, the user can feel better operation feeling and feedback hand feeling because the friction force is adjustable. However, when the angle of rotation is large, the chassis needs to be tilted or inverted to be adjustable, which is quite inconvenient.

Another example is a display stand of CN207687603U, which is mainly used to carry portable ultrasonic diagnostic equipment, and a shaft is vertically arranged on a base. The end of the hollow lower side arm is inserted into the shaft in a freely rotatable manner. The upper side arm is connected with the top end of the lower side arm through a rotary joint. The bracket is connected to the front end of the upper arm by a swivel joint for tilting. The shaft is formed by embedding a portion of a cylindrical shaft body into an annular sleeve. The sleeve has a circular arc-shaped section in the circumferential direction around the rotation axis, and has a circular or oval outer peripheral shape in the other sections. The resin gasket supported by the lower arm is pressed against the outer peripheral surface of the sleeve. The spacer slides on the outer peripheral surface of the sleeve in accordance with the rotation of the lower arm. The operator can perceive the degree of the frictional resistance and the stable condition of the frictional resistance according to the operation load, and intuitively understand that the lower arm is far away from the movable limit. Although the lower arm, the upper arm and the bracket can be rotated simultaneously, the stability of the overall rotational positioning is obviously insufficient, that is, the structure disclosed in chinese patent CN207687603U can rotate the lower arm, the upper arm and the bracket simultaneously to slightly position at a plurality of angles, but cannot generate a very stable and definite positioning effect.

Two sides of the body 46 are respectively provided with a long hole 465,465 ', two long holes 465, 465' respectively accommodate a compression spring, the compression spring is used as the first elastic member 44, one end of each of the two first elastic members 44 respectively presses against two second lower side plates 418,418 'of the lower frame 412 of the frame 41, and the other end of each of the two first elastic members 44 respectively presses against inner hole end walls of the long holes 465, 465' at two sides of the body 46, thereby enabling the positioning member 43 to elastically reciprocate. Additionally, the bottom of the body 46 has a T-shaped guide 466. The top surface of the positioning portion 47 has an accommodating space 471 with an open end for accommodating a second elastic member 45, and two ends of the second elastic member 45 respectively press against the sidewall of the T-shaped guide slot 466 of the body 46 and a sidewall of the accommodating space 471, so that the positioning portion 47 can elastically reciprocate linearly in the T-shaped guide slot 466 relative to the body 46.

Under a normal state, the positioning portion 47 can be pressed against the periphery of the turntable 3 by the elastic force of the second elastic member 45. As shown in fig. 3, 8-10, after the user presses the pressing portion 461 from the outside of the seat body 2 for the first time, the positioning member 43 can move inward relative to the guiding member 42, so that the two first elastic members 44 and the second elastic member 45 respectively form a compressed state, and at the same time, one end of the connecting rod 464 moves through the first half-guiding groove 424 of the heart-shaped guiding groove 423 and stops in the limiting concave portion 426, and at this time, the positioning portion 47 more tightly presses the periphery of the rotary plate 3 through the elastic action of the second elastic member 45. As shown in fig. 1, 11 and 12, when the bracket 9 and the base 2 rotate relative to the turntable 3 at the same time, and the positioning portion 47 faces the positioning slot 32 of the upper turntable 3, the positioning portion 47 will pop out to be engaged with the positioning slot 32, so as to be positioned at a predetermined angle: in practice, when there are a plurality of positioning slots 32, the bracket 9 and the base body 2 can be rotated simultaneously to be positioned at different angles.

As shown in fig. 13-15, when the user presses the pressing portion 461 for the second pressing, one end of the connecting rod 464 disengages from the limiting concave portion 426 and moves through the second half guiding groove 425 of the heart-shaped guiding groove 423 to return to the original position of the heart-shaped guiding groove 423, so that the positioning portion 47 can be separated from the positioning groove 32 to unlock, and the bracket 9 and the seat body 2 can rotate at an unspecified angular position relative to the rotating disc 3.

In summary, the pressing portion of the present invention protrudes out of the base, and after the first pressing of the pressing portion is performed through the heart-shaped guide slot structure, the bracket and the base can rotate relative to the turntable at the same time, so as to be stably and certainly positioned at a predetermined angle; after the pressing part is pressed for the second time, the locking between the base body and the rotary disc can be released, and the support and the base body can rotate at any position relative to the rotary disc simultaneously, so that the touch control operation of a user can be facilitated, and the rotation angle can be adjusted conveniently and effectively.
