The patent number CN202210747579.2 of the applicant in 2022 is an electric sliding door transmission structure and a sliding door, which can transmit the motion of the door body to a power transmission bracket through a circulating rope wheel and a circulating rope, and then directly push the next door body to move through the power transmission bracket, so that the quick and stable motion of the sliding door is realized. The working principle is described in detail in the cited patent and is not described too much here.

The door body of the sliding door is made of aluminum alloy sections, as shown in figures 1-3 (not shown in the original application) in the drawings of the specification, but the sections with the structure have the following defects: the lower part of the section bar is provided with an integral supporting roller installation cavity 1 for arranging a supporting roller 3 of a main driving fixed bracket, no special circulating rope installation cavity exists, and the circulating rope on each section of door body is connected with the next section of door body through a T-shaped connecting plate 2. Specifically, the circulating rope passes through rope holes 5 on the fixing studs 4, the fixing studs 4 are installed in two installation holes 6 on the connecting plate 2, and the circulating rope is tightly pressed through the fixing studs 4, so that the circulating rope is linked with the connecting plate 2. Therefore, the connecting plate 2 can only be hung below the section bar through the circulating rope, the guiding is lacking when the circulating rope moves, the circulating rope is exposed, and the connecting plate is easy to damage and is quite unattractive.

Disclosure of Invention

According to the defects in the prior art, the technical problems to be solved by the utility model are as follows: the utility model provides a section bar for automatically-controlled door sill, sets up circulation rope guide way, makes circulation rope set up inside the section bar to solve above-mentioned problem.

The lower part of the cross section of the section is a supporting roller installation cavity, the supporting roller installation cavity is provided with a downward opening, an upper guide groove and a lower guide groove are arranged on the same side of the supporting roller installation cavity, and the upper guide groove and the lower guide groove are also provided with openings.

In the scheme, the sliding block is arranged in the upper guide groove and is linked with the circulating rope, the upper section of the circulating rope is also positioned in the upper guide groove, the opening in the upper guide groove is used for connecting the sliding block with the connecting piece, and the sliding block is connected with the next door body through the connecting piece. The lower section of the circulating rope is positioned in the lower guide groove, and the end head of the circulating rope is connected with the main drive fixing bracket through a rope end fixing rod.

Preferably, to rationalise the structural design, the upper channel opening is directed to one side and the lower channel opening is directed downwards.

Preferably, the sum of the heights of the upper guide groove and the lower guide groove is identical to the height of the supporting roller mounting cavity.

Preferably, the widths of the upper guide groove and the lower guide groove are equal.

Compared with the prior art, the utility model has the following beneficial effects:

compared with the prior art, the sectional material for the bottom beam of the automatic door has a more reasonable structure, can replace a connecting plate by the sliding block, is arranged in the upper guide groove, is also positioned in the upper guide groove, is positioned in the lower guide groove, plays a role in guiding the movement of the circulating rope, and also plays a role in protecting the circulating rope from damage. And the circulating rope and the sliding block are both positioned in the section bar, so that the appearance of the telescopic door is more attractive.
