Working principle: In the traditional technology, the upper end of the folding door is installed in the guide rail 1 at the top of the cabinet by hoisting the guide wheel set to slide. Due to the influence of the installation accuracy between the guide wheel set and the cabinet, and the manufacturing accuracy of the guide wheel connecting plate, etc. After the folding door is installed, when the guide wheel group slides in the guide rail 1, it is likely to run smoothly, and the rear of the folding door is parallel. Therefore, in the traditional technical installation, the requirements for each size are very strict, otherwise the above problems will occur, so the installation process needs to be very careful and repeatedly measure each size. In view of this situation, in this case, an adjustment screw is provided in the installation frame to screw with the adjustment screw hole in the guide connecting plate. The specific adjustment is to use a tool such as a Phillips screwdriver to rotate the cross rotating head of the adjusting screw, so as to drive the guide plate on the connecting plate of the guide wheel to slide along the guide groove, and convert the rotational motion of the adjusting screw into the linear motion of the guide plate, so that the The guide wheel connecting plate moves relative to the installation frame, and indirectly drives the displacement between the guide wheel and the guide rail to achieve the purpose of adjusting the position of the guide wheel to achieve the best use state, so that the guide wheel and the guide rail 1 can be seamlessly connected to ensure folding. The door is smooth and stable during operation, improving its service life and safety.

Further, the two sides of the lower end of the guide plate protrude outward from the body and are provided with limit platforms, which are clamped on the limit pins in the installation frame to prevent the guide connecting plate from derailing or colliding when the adjustment is excessive. At the same time, a limit groove is set in the lower cover plate installed under the installation frame, and the limit ring of the adjustment screw is clamped in the limit groove, which effectively restricts the adjustment screw from always being located in the installation frame, so there is no need to worry about the adjustment of the adjustment screw The excess is loosened from the guide plate 21 , which avoids the potential safety hazard caused by the door panel falling easily after the two are loosened in the traditional technology, so it can be widely used.
