Description

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

Technical field:

The invention relates to the field of one-way rotating mechanisms, in particular to a method for realizing reverse barrier-free rotation of a one-way rotating mechanism.

Background technique:

At present, most of the conventional one-way rotary transmission mechanisms are two rotating bodies that rotate in one direction at the same time. The rotation of one rotating body must drive the other rotating body to rotate in the opposite direction, but if one of the rotating bodies is required 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. In practical applications, for example, when designing a flipping platform, the flipping platform is equivalent to a rotating body, one end is connected by a rotating shaft and a fixed hinge support, and provides support for one end of the flipping platform, while the other end needs a rotatable support To provide support, if a fixed support is used, in order to support the other end of the flipping platform, the fixed support must be located within the rotation radius of the flipping platform. During the flipping process of the flipping platform, the fixed support will Interference occurs, which hinders the turning of the turning platform, so that the turning platform cannot bypass the fixed support and continue to turn. When choosing the flipping support, because the flipping support can provide support for the platform, the flipping base should be one-way rotation, and a braking device is required in the other direction to provide support for the flipping platform, that is, the flipping base can only be used with A one-way rotation action in which the platform rotates in the opposite direction. When the flipping platform needs to rotate in the reverse direction and fall down, the reverse rotation of the flipping seat is provided with a braking device, which hinders the reverse rotation of the flipping platform. When it needs to be dropped, since the turning seat cannot realize the rotation avoidance, the turning platform cannot rotate in the opposite direction to realize the falling action.

Invention content:

The purpose of the present invention is to provide a method for realizing reverse unobstructed rotation of a one-way rotating mechanism, which solves the problem that the traditional one-way rotating mechanism cannot realize reverse rotation.

The above purpose is achieved through the following technical solutions:

A reverse barrier-free rotating device of a one-way rotating mechanism, which is composed of: a rotating body A, a rotating body B, the centers of the rotating body A and the rotating body B are connected by a rotating shaft and a fixed hinge support, so The rotating body A rotates in one direction, and a braking device is provided for rotating in the opposite direction.

(3) When the rotating body B needs to rotate in the reverse direction, the space-occupying device 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 is rotated. Rotate a certain angle, and the rotation angle is smaller than the braking angle, which provides a rotating space for the reverse rotation of the rotating body B. During the reverse rotation of the rotating body B, the space-occupying device always abuts on the rotating body A, and the rotating body A is on itself. Under the action of the reversal force, it gradually rotates with the rotation of the rotating body B. When the rotating body B reversely rotates to the braking position of the rotating body A, the rotating body A stops rotating;

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

In the figure: 1. Rotating body A, 2. Rotating body B, 3. Occupying device.

Detailed ways:

Example 1:

A reverse barrier-free rotating device of a one-way rotating mechanism, which is composed of: a rotating body A1, a rotating body B2, the centers of the rotating body A and the rotating body B are connected by a rotating shaft and a fixed hinge support, so The rotating body A described is unidirectional rotation, and a braking self-locking device is provided for rotation in the opposite direction. The rotating body B can realize bidirectional rotation when it is not restricted by external conditions, and the rotating body B is connected with a space-occupying device. 3.

Example 2:

A method for realizing reverse barrier-free rotation using the one-way rotating mechanism described in Embodiment 1, the method comprising the steps of:

(1) One-way rotation is performed between the rotating body A and the rotating body B, wherein the rotating body A is a one-way rotation, a braking device is provided in the opposite direction, and the rotating body B is a two-way rotation when it is not restricted by external conditions;

(2) The rotating body A can automatically reversely rotate to the previous braking position through its own reversal force within a certain angle range. When the rotating body A rotates beyond the set braking angle, the reverse braking is triggered. When the rotating body A cannot rotate in the opposite direction through its own reversal force;

(3) When the rotating body B needs to rotate in the reverse direction, the space-occupying device 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 is rotated. Rotate a certain angle, and the rotation angle is smaller than the braking angle, which provides a rotating space for the reverse rotation of the rotating body B. During the reverse rotation of the rotating body B, the space-occupying device always abuts on the rotating body A, and the rotating body A is on itself. Under the action of the reverse force, it gradually rotates with the rotation of the rotating body B. When the rotating body B reversely rotates to the braking position of the rotating body A, the rotating body A stops rotating;

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

The rotating body A rotates continuously in one direction. Within a certain angle range (not exceeding the braking angle), it can rotate in the opposite direction through its own reversal force, that is, within the two braking ranges, the rotating body A can automatically reverse the direction. Swing back 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 section. 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 Perform the reverse rotation. In this method, the front end of the rotary body B is gradually filled with the front end of the rotary body B from the outside of the rotation radius of the rotary body B with a space-occupying device, so that the rotary body A is rotated from the braking position by a certain angle, so as to be a countermeasure for the rotary body B. Provide enough rotation space for the rotation to realize the unobstructed reverse rotation of the rotating body B.

When the rotating body B needs to rotate in the reverse direction, firstly rotate the rotating body B by a certain angle according to the original rotation direction to form a certain inclination angle with the rotating body A, but it does not reach the braking position. The outside of the turning radius gradually moves closer to the end of the rotating body B. During the approaching process, the space-occupying device turns 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 rotating body A. Obstructing the reverse rotation of the rotating body B, realizing the unobstructed rotation of the rotating body B in the opposite direction. When the rotating body B rotates in the opposite direction, the rotating body A rotates along with the rotating body B under the action of its own reversal force, and the rotating body A does not rotate when it returns to the previous braking position.

Example 3:

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

When the rotating body B is tentatively set as the power input end, the rotating body B is rotated to drive the rotating body A to rotate. Since the rotating body A rotates in one direction and has a braking function when it rotates in the opposite direction, it has a braking function. When the rotating body B rotates in the reverse direction, it will encounter the obstacle 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 rotate the rotating body B by a certain angle in the original direction. Gradually fill up the end of the rotating body B, and drive the rotating body A to rotate during the process of the space-occupying device moving closer. The rotation angle of the rotating body A is smaller than the braking angle. When the space-occupying device completely occupies 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 occupying 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 to rotate correspondingly under the action of its own reversal force until it reaches its position. The braking position is stopped, so that the reverse rotation of the rotating body B is realized.
