Description

Rotation lock base

This creation is about a rotary locking base, especially a kind of one that allows the bracket and the base to rotate relative to the turntable at the same time, and can be positioned stably and accurately.

At present, the common flat electronic devices such as tablet computers or AIO computers are mostly supported by a support tripod to allow the flat electronic device to stand. Therefore, the display device can be rotated and positioned horizontally, and the tablet computer can be positioned at different angles, so as to facilitate the user's touch operation. Among them, the pivoting mechanism mainly includes a central bearing group and a plurality of limit screws on the periphery. The limit screws can slide in the set arc grooves, so that when the display is stressed, it can slide due to the preset limit screws. The path is rotated relative to the base by means of a centrally located bearing set. However, the above-mentioned support device only allows the display to have a basic pivoting function, but does not take into account the different requirements of displays of different specifications and sizes, so that when mounting displays of other sizes and weights, the operation may not be smooth. produce.

Therefore, such as the "rotatable support device" of TW M514534U, a solution is proposed, which mainly includes a bracket, a chassis, and an adjustable structure connected between the bracket and the chassis. The adjustable structure uses multiple The axial coordination of the company uses the interference degree of the meshing structure between the washers to adjust the external force required to drive the bracket and the adjustable structure to rotate relative to the chassis. In this way, the user can select an appropriate segment according to specifications such as the size and weight of the screen, and even operating habits such as the force application position. And through the degree of engagement and interference in the adjustable structure, the friction force in the structure is changed, and the force exerted by the user on the display is transmitted to the rotating structure and overcomes the aforementioned friction force, the display can be driven to make it horizontal. The angle can be adjusted by rotating the surface; and in the process of operation, the user can feel a better operation feeling and feedback feeling because the friction force is adjustable. However, when it is rotated, the chassis needs to be tipped or upside down before it can be adjusted, which is quite inconvenient.

Another example is a "display stand" in CN207687603U, which is mainly used for carrying a portable ultrasonic diagnostic device, and a shaft is erected on the base. The end of the hollow lower arm is inserted into the shaft in a freely rotatable manner. The upper arm is connected to the top end of the lower arm through a swivel joint. The bracket is connected to the front end of the upper arm through a tilting swivel joint. The shaft is formed by inserting a portion of a cylindrical shaft body into an annular sleeve. A portion of the sleeve in the circumferential direction has a circular arc shape centered on the rotation axis, and the other regions have a circular or oval outer peripheral shape. The resin spacer 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 as the lower arm rotates. Thereby, the operator can perceive the degree of frictional resistance and the stability of the frictional resistance according to the operation load, and intuitively understand that the lower arm is far away from the movable limit. Although it can make the lower arm, the upper arm and the bracket rotate at the same time, it is obviously insufficient in the stability of the overall rotation and positioning, that is, the structure disclosed in the CN207687603U case can make the lower arm, the upper arm and the bracket rotate at the same time. Slightly positioned at multiple angles, but does not produce a very firm and definite positioning effect.

In view of this, in order to provide a structure that is different from the conventional technology and improve the above-mentioned shortcomings, the creator has accumulated many years of experience and continuous research and development improvement, so this creation came into being.

One of the purposes of this creation is to provide a rotary locking base, which can solve the problems that the conventional "rotatable support device" is inconvenient to adjust the rotation angle, and the "display stand" cannot produce a very stable and definite positioning effect. Through the heart-shaped guide groove structure, after the first pressing, the bracket and the base can be rotated relative to the turntable at the same time, so as to be firmly and firmly positioned at a preset angle When you press it for the second time, the lock can be unlocked, so that the bracket and the base can rotate at any position relative to the turntable at the same time, which is very convenient when adjusting the rotation angle.

In order to achieve the purpose of the above creation, the rotation locking base set in this creation includes a base, a turntable and a pressing and positioning module. The seat body has a rotating space with an open bottom surface, and the top surface of the seat body is connected with a bracket; the turntable is connected with the seat body by a rotating shaft, so that the turntable can be accommodated in the rotating space by means of rotation, and the bottom surface of the turntable is protruding from The bottom surface of the seat body and the periphery of the turntable have at least one positioning groove; the pressing and positioning module includes a guide piece and a positioning piece, the guide piece is connected to the base body, and an end surface of the guide piece has a heart-shaped guide groove, the center The shape guide groove has a limiting concave part; one end of the positioning piece has a pressing part, and the other end of the positioning piece has a positioning part for being limited in any positioning groove; the positioning piece has a connecting rod, one end of the connecting rod can be The movement mode is accommodated in the heart-shaped guide groove for the positioning member to move back and forth relative to the guide member.
