Description

Multi-functional back of the body fold type folding door

Technical field

The utility model belongs to the door that the house is installed, and relates in particular to the security insurance door.

Background technology

In order to make in the house shop security insurance on the street especially, all installing insurance outdoors now, security door, the former iron gates that adopt of this door more, because it is many that this door heaviness is occupied the space, and aesthetics is poor, therefore used the spool door again instead, the door leaf of spool door all is to adopt many aluminum alloy sheet to snap together, these door leafs are around on the volume of the rotating shaft on the door head when opening, this spool door takes up room little and attractive in appearance, but because its this structure makes door leaf to be made up of the not too big sheet material of many width, and the hardness of these materials and intensity can not be too greatly otherwise be difficult for rolling, so many aluminum alloy sheet snap together, not only processing trouble, and owing to throwing off easily at the snapping place, so influenced the safety of this door, whole door leaf will be around on the rotating shaft volume when opening for door in addition, when this door uses more long afterwards, owing to door can tilt, door leaf is just extremely inconvenient when opening, must repair or change, therefore this door is shorter application life.

Summary of the invention

It is a kind of that the purpose of this utility model is to provide, and safety is better, and is easy to use, and little multi-functional back of the body fold type folding door takes up room.

The purpose of this utility model is achieved through the following technical solutions:

A kind of multi-functional back of the body fold type folding door, comprise doorframe, door and door lock, door is made up of the frame on the both sides shop front middle with being packed in frame, doorframe top is the door head, door is by forming more than two sections, and facing mutually has hinge to connect between two sections, and a door both sides respectively install a spring, the lower end of spring is packed in respectively on the doorjamb, and the upper end of superior segment door is linked by the hinge and the head of calling.

Door lock is mounted in it on one section, and a grab is respectively adorned at the two ends of the expansion link of door lock, so that folding door grab when locking can tighten doorframe.

Superior segment door and the hinge of being adorned between the head to the doorstep are contained in the external surface of the shop front, connect the inner face that hinge between superior segment door and the second section door is contained in the shop front, and the connection hinge between three sections doors of second section Men Yudi is contained in the external surface of the shop front.

The grab at door lock expansion link two ends is set on the rotational pin that is fixed on the doorframe, and door lock is contained on second section door.

Head is a flute profile to the doorstep, it is packed in the doorframe top, one side of spring is spirality, in spiral one section groove that is contained in head to the doorstep, the termination of this section is fixed on the groove inwall, door by following position movable pulley is housed, movable pulley contacts with doorframe, it rolls along doorframe in the door pull-up or when putting down, so that light.

Door is divided into three sections, and the door of epimere and second section is made for the metal sheet that is fixed on the frame, is pressed with reinforcing rib on the metal sheet, and the 3rd section the shop front is made for being fixed on the frame tubing.

The door of this folding door is made up of the frame and the shop front that is packed on the frame, door is only formed by several sections, therefore intensity is good, each section of door reaches and the connecting of head to the doorstep of doorframe all adopts hinge, and they are upwards started by the pulling force of spring, therefore no matter this set-up time has and how long all can open easily by the utmost point, the shop front of this door can adopt any thickness of material, even can adopt reinforcing bar and tubing to make, so it has good safety, because this door is to upwardly open to be folded state after other door is opened, and takes up an area of little advantage so it has, it also plays the effect of a cover edge.
