Engaged structure for telescopic gate sheet

Abstract

The invention discloses a door plate meshing and coordinating structure for a telescopic door, comprising a plurality of door plates arranged in the telescopic doorframe body; the door plates are provided with transverse connecting rods; two ends of the transverse connecting rods are articulated with moveable post columns and door body post columns; the door body post columns are arranged on the telescopic doorframe body; the invention is characterized in that: the transverse connection rods are provided with racks; the connection ends of the racks and the door body post columns are provided with gears; the gears of transverse connection rods of two adjacent door plates occlude with each other; the transverse connection rods of two adjacent door plates are integrated into a whole through the moveable post columns. The door plates of the invention can be folded and unfolded at the same time, the door plates are stable after being unfolded, the structure is simple, economical and practical.

Description

technical field [0001] The invention relates to the field of telescopic doors, and more specifically relates to a door sheet connection structure of telescopic doors. Background technique [0002] At present, there are various forms of telescopic doors on the market. The more common ones are folding telescopic doors, which are directly hinged with multiple door pieces, generally including The machine head assembly, the machine head assembly and the lower part of the telescopic door frame are all equipped with driving wheels or road wheels, the number of which is more than three odd-numbered door pieces and two half-width door pieces whose width is 1 / 2 of the door piece width. The blades are hinged at the head and tail, and a connecting rod with a length equal to the width of the door is set on each door. The connecting rod and the door are hinged at the center of the length of the connecting rod and the center of the width of the door. Sequentially hinged, so that the opene...

[0002] At present, there are various forms of telescopic doors on the market. The more common ones are folding telescopic doors, which are directly hinged with multiple door pieces, generally including The machine head assembly, the machine head assembly and the lower part of the telescopic door frame are all equipped with driving wheels or road wheels, the number of which is more than three odd-numbered door pieces and two half-width door pieces whose width is 1 / 2 of the door piece width. The blades are hinged at the head and tail, and a connecting rod with a length equal to the width of the door is set on each door. The connecting rod and the door are hinged at the center of the length of the connecting rod and the center of the width of the door. Sequentially hinged so that the opened door has a larger plane and the door has good shielding; the disadvantage of this structure is that the door sheet is not stable during the unfolding process, there is no linkage between the door bodies, and it is not easy to replace the door sheet when it is damaged

For this reason, people improve the door leaf connecting structure of existing telescopic door, set upper and lower transverse connecting rods in the door leaf of telescopic door frame body, the middle of upper and lower transverse connecting rods is connected together by longitudinal rotating shaft, the upper and lower transverse connecting rods The two ends are respectively connected to the longitudinal links on both sides. The upper and lower transverse links and the longitudinal links at both ends constitute a scissor-type four-link door structure. The longitudinal links of this structure penetrate into the holes of the upper and lower transverse links and are hinged. It can be replaced separately, but due to the many joints of the two transverse connecting rods superimposed on each other in the scissor-type four-link door structure, the connection is complicated, the installation is inconvenient, and the cost is high
