Embodiment 1

[0022] As shown in Figure 1, it is a schematic diagram of the overall structure of this embodiment. The retractable door of this embodiment includes a door head 1, a door frame 2 and walking wheels 3, wherein the door head 1, door frame 2 and walking wheels 3 are similar to ordinary telescopic doors. Walking wheel 3 is installed on door head 1 and door frame 2 bottoms. The door frame 2 is composed of several door rows. Two mother-child slide rail devices 4 are installed in the lower part of the door frame 2 in parallel. One end of each mother-child slide rail device 4 is fixed on the ground, and the other end is fixed at the joint between the door head 1 and the door frame 2. . The door frame 2 is expanded or contracted through the motion guidance of the mother-to-child slide rail device 4. The mother-to-son slide rail device 4 includes: a mating mother part 42, which is used to guide and accommodate the inserted sub-parts, so that the door frame can be kept in the correct sta...

Embodiment 2

[0024] As shown in Figure 5, it is a schematic diagram of the local structure after telescopic assembly of this embodiment. The telescopic door of this embodiment includes a door head 1 (not shown in the figure), a door frame 2 and walking wheels 3, wherein the door head 1, door frame 2 Similar to the common retractable door with the traveling wheel 3, the traveling wheel 3 is installed on the door head 1 and the door frame 2 bottoms. In addition, a mother-child slide rail device 4 is also installed at the bottom of the telescopic door in this embodiment. The mother-child slide rail device 4 is composed of an embedded sub-piece 41, a small fitting mother part 45, a middle fitting mother part 47, a large fitting mother part 42 and several sliding balls 44, and the sliding balls 44 pass through the sliding plate 440 are embedded at intervals between the inserting sub-piece 41 and the small fitting female part 45, between the small fitting female part 45 and the middle fitting fe...

Embodiment 3

[0027] This embodiment is similar to Embodiment 2, the difference lies in that the mating mother parts of the mother-child slide rail device 4 are directly and smoothly matched without sliding balls. In this way, the process can be simplified and the cost can be saved. In addition, the limit block 5 is composed of a Π connecting frame 51, a rotating connecting column 52, a wear-resistant sleeve 53 and a roller 54, and the roller 54 is installed on the bottom of the Π connecting frame 51. Such a structure increases the stability of the telescopic door when it moves. The principle is the same as in embodiment 2.

[0028] Fig. 8 is a schematic diagram of component assembly of the mother-child slide rail device and the limit block in this embodiment.

Abstract

The invention relates to a flexible door, and comprises a door head, a door frame and a road wheel arranged under the door head and the door frame, wherein, the telescopic motion of the door frame performs the guide function through secondary and master slide rail devices. The secondary and master slide rail devices comprise at least an inserted master element, and is used to guide and hold the inserted sub-element, to ensure that the door fame is held under an accurate status of a straight line operation; at least an inserted secondary element, and enables the each part of the master and secondary elements to be inserted a whole in a sliding way through the movement of the inserted secondary element in an inserted master element direction, in order to ensure that the door frame is held under an accurate status of a straight line operation. The usage of the invention can omit the laying of a pavement track, the cost is saved; and the guide function of the secondary and master slide rail devices ensures the reliability of the flexible door movement, the operational effect is obvious, and the assembly and the maintenance are convenient.

Description

technical field [0001] The invention relates to an automatic door, in particular to a new telescopic door with mother-to-child sliding rails. Background technique [0002] At present, because the automatic door series products have the characteristics of beauty, exquisiteness and convenient opening and closing, they have been widely used in the courtyard doors of government agencies, colleges, factories and residential quarters, etc., and with the rapid development of social and economic construction, other The market demand is increasing. In summary, all types of automatic doors today can basically be divided into three categories: one is the electric telescopic doors with different shapes and styles derived from the working principle of the vertical door row structure, such as the patent " An automatic telescopic door" (Patent No. 00211484.4); the second is a screen-type telescopic door composed of a door frame, screen piece, hinge, roller, etc., such as the patent "A Scr...
