Problems solved by technology

Its disadvantage is that when the size of the middle door body changes according to the design requirements, the length of the belt or chain between the two gears also changes, which must be customized according to actual needs, resulting in insufficient applicability of the triple-action door during installation, which is very serious. Inconvenient, not suitable for mass production

Abstract

The invention discloses a three-linkage door. The three-linkage door comprises an upper door frame, a lower door frame, a first outer door body, a second outer door body, a middle door body, and a linkage device arranged on the top of the middle door body, wherein the middle door body is clamped between the first outer door body and the second outer door body. In the three-linkage door, the linkage device replaces the conventional belt and chain for linkage transmission; during installation, linear transmission shafts with different lengths can be used or the connecting depth of a shaft post at a near shaft end and the linear transmission shaft can be regulated according to the width of the middle door body, so that a space between two driving gears is changed to meet actual installation requirements of the three-linkage door; a trouble of customizing a belt and a chain is avoided; the problem that the adaptability during the installation of the three-linkage door is insufficient is solved; the three-linkage door is flexible in structural change and durable; noises are avoided in the driving process of the three-linkage door; and installation requirements and using requirements are met well.

Description

technical field [0001] The invention relates to a triple linkage door. Background technique [0002] At present, in the construction and decoration industry, there are many triple-linkage doors used in shower rooms. There is a kind of triple linkage door on the market at present, rack is set on the front door body and the rear door body, two gears are set on the middle door body, and the three door bodies reach the linkage effect by the belt or chain between the two gears. Its disadvantage is that when the size of the middle door body changes according to the design requirements, the length of the belt or chain between the two gears also changes, which must be customized according to actual needs, resulting in insufficient applicability of the triple-action door during installation, which is very serious. Inconvenient, not suitable for mass production. Contents of the invention [0003] The object of the present invention is to provide a three-linkage door with flexible ...
