Method for realizing reverse obstacle-free rotation of one-way rotating mechanism

Abstract

The present invention relates to a method for achieving reverse barrier-free rotation of a one-way rotating mechanism. At present, most of the conventional one-way rotating transmission mechanisms have two rotating bodies that rotate in one direction at the same time. The rotation of one rotating body will inevitably drive the other rotating body to rotate in the opposite direction. However, if one of the rotating bodies needs to rotate in the opposite direction, since the other rotating body is provided with a braking device for reverse rotation, it will become an obstacle to its reverse rotation. The composition of the present invention includes: a rotating body A (1), a rotating body B (2), the centers of the rotating body A and the rotating body B are connected by a rotating shaft and a fixed hinge support, the rotating body A is unidirectionally rotating, and a braking device is provided for reverse rotation, the rotating body B is bidirectionally rotating when not restricted by external conditions, and the rotating body B is connected with a placeholder device (3). The present invention is used for a reverse barrier-free rotation device of a one-way rotating mechanism.

Description

Technical field:

[0002] The invention relates to the field of one-way rotating mechanisms, and in particular to a method for a one-way rotating mechanism to achieve reverse obstacle-free rotation. Background technology:

[0004] At present, most of the conventional unidirectional rotation transmission mechanisms have two rotating bodies that rotate unidirectionally at the same time. The rotation of one rotating body must drive the other rotating body to rotate in the opposite direction. However, if one of the rotating bodies needs to rotate in the opposite direction, since the other rotating body is provided with a braking device for reverse rotation, it will become an obstacle to its reverse rotation, making this action impossible to achieve. In practical applications, for example, when designing a flip platform, the flip platform is equivalent to a rotating body, one end of which is connected by a rotating shaft and a fixed hinge support, and provides support for one end of the flip platform, while the other end requires a rotatable support to provide support. If a fixed support is used, in order to be able to support the other end of the flip platform, the fixed support seat must be located within the rotation radius of the flip platform. During the flipping process of the flipping platform, the fixed support will interfere with the flipping platform, hindering the flipping of the flipping platform, resulting in the flipping platform being unable to bypass the fixed support and continue to flip. When selecting a flip support, since the flip support can provide support for the platform, the flip seat should be unidirectionally rotating, and a braking device is required in the other direction to provide support for the flip platform, that is, the flip seat can only perform a unidirectional rotation action opposite to the rotation direction of the flip platform. When the flip platform needs to rotate in the opposite direction to fall, the flip seat is provided with a brake device for the reverse rotation, which hinders the reverse rotation of the flip platform. The flip platform can push the flip seat away and rotate upward, but when the flip platform needs to fall, the flip seat cannot rotate to avoid, so that the flip platform cannot rotate in the opposite direction to achieve the falling action. Summary of the invention:

[0006] The purpose of the present invention is to provide a method for a one-way rotating mechanism to achieve reverse barrier-free rotation, thereby solving the problem that a traditional one-way rotating mechanism cannot achieve reverse rotation.

[0007] The above purpose is achieved through the following technical solutions:

[0008] A one-way rotating mechanism reverse barrier-free rotating device, which comprises: a rotating body A and a rotating body B. The centers of the rotating body A and the rotating body B are connected through a rotating shaft and a fixed hinge support. The rotating body A rotates in one direction and is provided with a braking device for reverse rotation. The rotating body B rotates in both directions when not restricted by external conditions, and the rotating body B is connected with a placeholder device.

[0009] A method for realizing reverse barrier-free rotation of a one-way rotating mechanism, the method comprising the following steps:

[0010] (1) The rotating body A and the rotating body B rotate in one direction, wherein the rotating body A rotates in one direction and is provided with a brake device for the reverse direction, and the rotating body B rotates in both directions when not restricted by external conditions;

[0011] (2) The rotating body A can automatically rotate in the reverse direction to the previous braking position within a certain angle range by its own reverse force. When the rotating body A rotates beyond the set braking angle, the reverse braking is triggered. At this time, the rotating body A cannot rotate in the reverse direction by its own reverse force;

[0012] (3) When the rotating body B needs to rotate in the opposite direction, the spacer on the rotating body B gradually fills the front end of the rotating body B from outside the rotation radius of the rotating body A, and drives the rotating body A to rotate, so that the rotating body A rotates a certain angle, and the rotation angle is less than the braking angle, so as to provide a rotation space for the reverse rotation of the rotating body B. During the reverse rotation of the rotating body B, the spacer always presses against the rotating body A. The rotating body A gradually rotates with the rotation of the rotating body B under the action of its own reverse force. When the rotating body B rotates in the opposite direction to the braking position of the rotating body A, the rotating body A stops rotating;

[0013] (4) When the rotating body A reaches the braking position, the rotating body A can provide support for the rotating body B.

[0014] Beneficial effects:

[0015] The present invention is a method for realizing reverse barrier-free rotation of a one-way rotating mechanism, which solves the problem that the traditional one-way rotating mechanism cannot realize reverse rotation. The method realizes the reverse rotation of one rotating body in two one-way rotating mechanisms by adding a place-taking device. When the rotating body with reverse braking reaches the braking position, it can provide support for the other rotating body. The present invention provides a feasible support method for the flip platform and other flip mechanisms. Description of the drawings:

[0021] Embodiment 1:

[0022] A one-way rotating mechanism reverse barrier-free rotating device, which comprises: a rotating body A1, a rotating body B2, wherein the centers of the rotating body A and the rotating body B are connected via a rotating shaft and a fixed hinge support, the rotating body A is unidirectionally rotating, and a braking self-locking device is provided for reverse rotation, the rotating body B can realize bidirectional rotation when not restricted by external conditions, and the rotating body B is connected to a placeholder device 3.

[0023] Embodiment 2:

[0024] A method for realizing reverse barrier-free rotation using the one-way rotating mechanism described in Example 1, the method comprising the following steps:

[0025] (1) The rotating body A and the rotating body B rotate in one direction, wherein the rotating body A rotates in one direction and is provided with a brake device in the opposite direction, and the rotating body B rotates in both directions when not restricted by external conditions;

[0026] (2) The rotating body A can automatically rotate in the reverse direction to the previous braking position within a certain angle range by its own reverse force. When the rotating body A rotates beyond the set braking angle, the reverse braking is triggered. At this time, the rotating body A cannot rotate in the reverse direction by its own reverse force;

[0027] (3) When the rotating body B needs to rotate in the opposite direction, the spacer on the rotating body B gradually fills the front end of the rotating body B from outside the rotation radius of the rotating body A, and drives the rotating body A to rotate, so that the rotating body A rotates by a certain angle, which is smaller than the braking angle, to provide a rotation space for the reverse rotation of the rotating body B. During the reverse rotation of the rotating body B, the spacer always rests on the rotating body A. The rotating body A gradually rotates with the rotation of the rotating body B under the action of its own reverse force. When the rotating body B rotates in the opposite direction to the braking position of the rotating body A, the rotating body A stops rotating;

[0028] (4) When the rotating body A reaches the braking position, the rotating body A can provide support for the rotating body B.

[0029] The rotating body A rotates continuously in one direction, and can rotate in the opposite direction by its own reversing force within a certain angle range (not exceeding the braking angle), that is, within the two braking ranges, the rotating body A can automatically rotate in the opposite direction to its previous braking position. When the rotation angle of the rotating body A exceeds the set braking angle, the rotating body A enters the next braking interval. In this case, the rotating body A and the rotating body B can only rotate in a single direction, so that the rotating body B cannot rotate in the opposite direction. The method is to use a space-occupying device at the front end of the rotating body B to gradually occupy the front end of the rotating body B from the rotation radius of the rotating body A, so that the rotating body A can rotate a certain angle from the braking position, thereby providing sufficient rotation space for the reverse rotation of the rotating body B, and realizing the reverse barrier-free rotation of the rotating body B.

[0030] When the rotating body B needs to rotate in the opposite direction, the rotating body B is first rotated in the original direction by a certain angle to form a certain inclination angle with the rotating body A, but before reaching the braking position, the spacer device gradually moves from the maximum turning radius of the rotating body A to the end of the rotating body B. During the process of moving closer, the spacer device moves the rotating body A counterclockwise to drive the rotating body A to rotate, providing space for the reverse rotation of the rotating body B, thereby eliminating the obstruction of the rotating body A to the reverse rotation of the rotating body B, and realizing the unimpeded rotation of the rotating body B in the opposite direction. During the reverse rotation of the rotating body B, the rotating body A rotates with the rotating body B under the action of its own reverse force, and the rotating body A stops rotating when it returns to the previous braking position.

[0031] Embodiment 3:

[0032] The specific implementation steps of the method for realizing reverse barrier-free rotation of the one-way rotating mechanism according to Embodiment 1 or 2 are as follows:

[0033] When the rotating body B is temporarily assumed to be the power input end, Figure 1 and 2 , the rotating body A is driven to rotate by the rotation of the rotating body B. Since the rotating body A is unidirectional and has a braking function when rotating in the reverse direction, when the rotating body B rotates in the reverse direction, it will encounter the obstruction of the rotating body A and cannot continue to rotate. At this time, the rotating body A can play a supporting role for the rotating body B. When the rotating body B needs to continue to rotate in the reverse direction, it is necessary to first rotate the rotating body B in the original direction by a certain angle. At the same time, through the place-taking device, it gradually moves from the maximum rotation diameter of the rotating body A to the tooth end of the rotating body B, and gradually fills the end of the rotating body B. The process of the place-taking device moving closer drives the rotating body A to rotate. The rotation angle of the rotating body A is less than the braking angle. When the place-taking device completely fills the front end of the rotating body B, the rotating body A just does not hinder the reverse rotation of the rotating body B. After the place-taking device reaches the position, the rotating body B can avoid the obstruction of the rotating body A and rotate in the reverse direction. At this time, the rotating body A automatically follows the rotating body B under the action of its own reverse force to rotate accordingly until it reaches its braking position and stops, thereby realizing the reverse rotation of the rotating body B.
