Abstract

The utility model relates to a cross moved rolling curtain whose driving plate in the transmission motion is arranged on the upper part of the rolling drum of a curtain board and a curling tray which receives the winding of the curtain board is arranged on an inverted basin-shaped tray. The bottom board of a frame is provided with an upward reinforcing rib, etc., which causes the vertical dimension of the lower structure of the rolling drum of the curtain board to be smaller. The part which needs to be laid below the ground can be shallow, and therefore, the part can be arranged on the building floor. The utility model adopts the structure of the enginery clamping type taper, improved lower rail dust sealing and an improved hand actuator, and therefore, the maintenance is convenient, and the range of use is developed. The utility model is suitable for movable screens or dodge gates with broadloom and big hole openings of various buildings.

Description

Cross moved rolling curtain

A kind of horizontal mobile roller shutter is suitable as the movable barrier or the dodge gate at the big hole of width of building, the side roller shutter door of be particularly suitable for preventing fires purpose or antitheft purpose.

At present, places such as the gateway hole of building, shopper window, warehouse use in a large number vertical lift on roll up rolling door, as passage barrier or fire prevention, anti-theft rolling blind door.Advantage convenient, flexible, wide adaptability that last rolling door has is used widely.But last rolling door is subjected to horizontal Wind-Pressure Resistance ability and hangs the bigger restriction of own wt, can not make too wide.The shifted laterally rolling door is because of curtain plate vertically hangs, the reel side direction is placed, and laterally the Wind-Pressure Resistance ability is stronger, thereby can make broad to adapt to the requirement at especially big wide cut gateway hole.In the prior art, the reel of side rolling door crouches darker into ground, is installed on the building floor to be restricted, and difficulty is safeguarded also in its mounting or dismounting, and the perfect necessity of further improvement is arranged.

The purpose of this utility model provides a kind of side roller shutter of the cable traction type that has improved, and it is more shallow into the part on ground that it is crouched, and be convenient to installation and maintenance, to adapt to the needs that are installed on the building floor.

Used technical scheme is system to be led in transmission be positioned over top, and it is characterized in that: the curtain plate reel is by spool shaft, dial, and pallet and framework are formed;

The dial of a, curtain plate reel is installed in the dial axle via the dial core, and the dial axle is loaded in the top chock, and top chock is supported on going up on the plane, top of framework; Pallet is contained on the pallet core, and the pallet core is the back-off peviform, is installed on the pallet axle, and the pallet axle is loaded in the lower shaft bearing, and the lower shaft bearing stretches into the pallet in-core, is supported on the following baseplane of framework; Spool shaft is a hollow circular-tube, and peach shape dish is arranged on it, the spool shaft upper end become with the dial axle can along axis move radially fixedly connected, the lower end becomes dismountable fixedly connected by sleeve pipe with the pallet axle.

The finger that line is in the shape of a spiral arranged is housed on b, the dial, and finger center substantial alignment is wound in the curtain plate thickness central authorities on the peach shape dish of spool shaft.

In addition, also adopt mechanical clamping type finger structure, on curtain plate drum frame base plate, be provided with reinforcing rib upwards, adopted the hand-operated gear that improves the following rail dust seal device of mechanism and improved.

Horizontal mobile roller shutter of the present utility model, owing to adopted dial to place curtain plate reel top and pallet to be installed in structure on the pallet core of back-off peviform, the curtain plate reel is crouched can be more shallow into above ground portion, thereby can be installed on the building floor, and be convenient to maintenance and repair, opened up its scope of application.
