Description

Multi-link rotation angle control device and parking breaker including the same

The present invention relates to a device for adjusting a rotation angle of a link, and more particularly, to a device for adjusting a rotation angle of a multi-link and a parking breaker including the same.

A gate is installed in the parking lot to control the entry and exit of vehicles. These gates are located in the horizontal direction to block the entry and exit of the vehicle, and are located in the vertical direction to allow the entry and exit of the vehicle. And, most gates (or gate bars or parking breakers) are cantilevered (cantilever type) and reciprocate in a 90° range. Therefore, it is preferable to operate the gate to wait while maintaining the correct horizontal direction, then lift it vertically if necessary, and then return to the horizontal direction.

However, at the time of initial installation, it was difficult to install it to operate accurately in the horizontal and vertical directions. This is because even a small processing error, assembly error, or gap of each link, joint and parts for driving leads to a large position error at the end of the gate. And, it is frequent as a case in which the ground on which the parking lot gate is installed is inclined or curved. This appears to pose a risk of interfering with passing vehicles if the gate is apparently not kept tilted or raised vertically enough. Conventionally, in order to solve this drawback, parts of various sizes were prepared and appropriately selected to fit the field.

And, even if the parking gate installed in this way is aged or there is an external shock, sagging occurred. In this case, after-sales service was provided in such a way that the entire structure set was replaced or parts were replaced.

Therefore, there is an urgent need for research that can control the rotation angle of the gate simply and precisely so that the gate can rotate accurately vertically and horizontally from the road surface when the gate is opened and closed without additional equipment or additional process.

First, the closed state of the parking breaker as shown in FIGS. 1A to 2 will be described. Due to the rotation of the motor 5 , the first link 100 has a first joint 110 positioned on the drive shaft 190 (see FIG. 1A ).

At this time, the link stopper 220 of the second link 200 comes into contact with the top dead center stopper 140 . As the third link 300 connected to the second link 200 rotates, the central axis of rotation 230 overcomes the force of the spring 240 to position the gate 250 in the horizontal direction.

if. If the gate 250 is not exactly horizontal but inclined, the bolt, which is the top dead center stopper 140, is rotated in the forward or reverse direction using a +-shaped screwdriver or wrench. Then, while the second link 200 rotates around the first joint 110 , the third link 300 is rotated finely. Due to the rotation of the third link 300, the rotation center shaft 230 is rotated in the forward or reverse direction minutely, and accordingly, one end of the gate 250 is rotated in the forward or reverse direction finely, thereby causing the gate The other end of the 250 may be slightly raised or slightly lowered to align the overall horizontal state.
