Main frame for suspension type electric sliding door

Abstract

The invention relates to the field of electric sliding doors, in particular to a main frame for a suspension type electric sliding door. A technical scheme provided by the invention is as follows: a motor 2, a rail 3 and roller wheels 4 which are matched with the rail are arranged at one side of a back plate, which is fixed with a wall surface, on a main frame; door leaf fixing pieces 6 are connected to the roller wheels and the roller wheels are connected with the upper part of a door leaf 7 through the door leaf fixing pieces; and the motor drives the door leaf fixing piece and drives the roller wheels to roll along the rail through a transmission mechanism. The main frame for the suspension type electric sliding door is characterized in that only one working sliding rail is arranged on the rail 3; the roller wheels are in one-to-one correspondence with the door leaf fixing pieces; each roller wheel is further provided with an anti-prying plate 8; the anti-prying plates are fixed and connected with the door leaf fixing pieces; the lower part of each anti-prying plate is provided with a curved surface 9 which is matched with the cross section of the rail and through which the rail can pass; and the roller wheels are arranged in the space which is formed by the door leaf fixing pieces and the anti-prying plates. According to the main frame provided by the invention, the installation space of the main frame is saved, the structure is simple, the manufacture technology requirement is lower and the roller wheel faults are reduced, therefore the working position of the roller wheels in the rail is ensured, and the roller wheels can bear quite large door leaf accidental impact or lateral manmade sabotage.

Description

Technical field [0001] The invention relates to the field of electric doors, in particular to the field of suspension electric sliding doors. Background technique [0002] Suspended electric sliding door refers to a type of electric door in which the door leaf is an integral structure and is suspended under the main frame to move along the track in the main frame. Because this kind of door leaf can reach hundreds of kilograms in weight, is large in mass and relatively strong in resistance to damage, it is widely used in storage, supervision, and guarding. The side of the main frame of the traditional suspended electric sliding door is The glyph is fixed on the external wall (e.g. figure 1 (Shown), the motor drives two parallel sets of rollers to move synchronously along the track. The corresponding two sets of rollers are provided with support rods. The door leaf is in the middle of the suspension support rod. The movement of the rollers drives the door panel to realize the door...
