Preferably, through installing the dog on well low-speed passenger train wallboard, realize the purpose of quick fixed roll curtain, guarantee well low-speed passenger train at the operation in-process, roll up the curtain and steadily fix all the time. The end part of the pull rod adopts a fishbone-shaped design, so that the pull rod is fixed with the stop block and has certain aesthetic property.

Preferably, the top mounting and the side mounting of the roller shutter are realized by mounting the mounting brackets at the two ends of the left support and the right support and selecting different bolt hole positions.

Preferably, the reel mechanism is small and exquisite in design, and shields the internal mechanism through the housing, and when considering the aesthetic property of rolling up the curtain, also played the effect of protection rolling up the curtain.

Preferably, the pull rod, the housing and the winding drum are all made of aluminum alloy sections, and the stop block is also made of cast aluminum alloy materials. The product design is more portable, and the lightweight design concept is adopted in the design, so that the service life of the core winding drum mechanism is prolonged while the performance of the product is ensured.

Preferably, the integrated roller shutter module is designed, and only the roller shutter stop block and the roller shutter bracket are required to be mounted on the wallboard, so that the sun-shading function is realized.

The utility model discloses a technological effect and advantage:

1. the utility model discloses this external backstop formula is rolled up curtain, the installation is simple, only need with backstop piece and installing support fixed to the wallboard can, labour saving and time saving can compromise two kinds of mounting means of top dress and side dress again simultaneously, the top dress can be hidden the maximize field of vision of opening the door window in the roll of curtain mechanism completely in the wall roof board.

2. The utility model discloses but wide application in the manual transformation upgrading of drawing the curtain originally of well low-speed passenger train has improved the aesthetic property of product, and this product has been applied to each road bureau in batches, has realized large-scale production, and the central low-speed passenger train has played the key role with the renewal of rolling up the curtain product.

3. The utility model discloses a design of this external backstop formula book curtain, production low in manufacturing cost, and the installation is nimble, does not need special installation interface, only needs to adjust the length of reel or reel curtain cloth according to the requirement of difference, realizes the installation customization of different book curtain sizes.
