Description

TECHNICAL FIELD

[0001] The utility model relates to a curtain door side edge limiting track and belongs to the technical field of curtain door limiting technology. BACKGROUND

[0002] A curtain door is a kind of door that is made up of a plurality of door panels, which are connected in series and move up and down around a fixed roller in a fixed track. The two ends of the track are provided with limiting mechanisms. The core component of the limiting mechanism is a limit switch, which is usually installed on the side rail or the roller of the curtain door and connected to the control system of the curtain door. When the curtain door rises or falls to the set limit position, the door body or the related transmission component will trigger the limit switch, and the limit switch will send a signal to the control system, which will immediately stop the operation of the motor, thereby preventing the curtain door from rising or falling excessively and avoiding the door body from being separated from the track, damaging the motor or other components.

[0003] However, in practice, it has been found that most of the current limiting structures use springs for resetting. When the curtain panel touches the spring, it will push the spring on the side of the spring to compress, thereby pressing the limit switch to control. At this time, the curtain panel will also be subjected to the reaction force of the spring. Due to the good bending property of the curtain panel, the edge position of the curtain panel is prone to bending deformation after being subjected to the reaction force of the spring for a long time or being bumped, which causes the curtain panel to be unable to press the spring, resulting in the limit switch being unable to be triggered, thereby affecting the normal limiting of the curtain panel during movement. Moreover, the part of the curtain panel located inside the track will shake during lifting, causing the edge position of the curtain panel to rub against the inside of the track. Long-term rubbing can cause the edge position to wear out, and the rubbing can also remove the protective paint on the edge, causing the edge of the curtain panel to rust, and the rusted position can corrode the curtain panel from the inside, thereby affecting the service life of the curtain panel. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a curtain door side edge limiting track, which is provided with symmetrical limiting mechanisms to ensure automatic control of the curtain panel during movement and prevent the curtain panel from bending due to the reaction force of the spring.

[0012] The side of the trapezoidal slide block is further fixedly connected with a point control switch, and the point control switch is located on the inner side of the return spring.

[0013] When the curtain plate moves from top to bottom to the side of the trapezoidal slide block, the curtain plate is matched with the inclined surface of the trapezoidal slide block, so that the trapezoidal slide block slides to the inner side of the hollow shell, when the side of the curtain plate is attached to the vertical surface of the trapezoidal slide block, the point control switch is just in contact with the hollow shell, so as to cut off the power supply of the power unit driving the curtain plate, and the limiting effect of the curtain plate lifting is realized.

[0014] As a further technical scheme of the utility model, the side edge limiter comprises a U-shaped groove seat, the side of the U-shaped groove seat is fixedly connected with an auxiliary spring in a rectangular array, and the other side of the auxiliary spring is in contact with the side guide rail.

[0021] 2. In this utility model, the side positioners in the side guides limit the movement of the curtain panel, making it more stable when raising and lowering, and reducing friction between the curtain panel and the side guides. Furthermore, the positioning rollers in the U-shaped groove seats rotate as the curtain panel moves, reducing friction on the side of the curtain panel and thus slowing wear on the curtain panel's edges.
