Abstract

The utility model provides a folding steel screen door, which is mainly composed of a plurality of steel screen pieces. The utility model is characterized in that general accessories are arranged on a fastening plate which is pushed on a wall by a prism, and in addition, a turning pull wire and a turning spring are added in a traditional pull wire transmission mechanism; when the steel screen door is opened, the steel screen pieces can turn an angle and are contracted to one side of the door, and the occupied space is little; simultaneously, a key for closing the door and a key for opening the door respectively use a pull down type and a key type and are arranged inside and outside the door, so the door is opened and closed with hands or feet. The utility model solves the problems that the occupied place is larger after the door is opened; a plastic screen door and a plastic screen window are easy to damage; the hands must be used for opening and closing the door, etc., and the folding steel screen door is convenient to prevent insects and small animals from entering the door and the window points in a room.

Description

Folding steel screen door

The utility model belongs to the building window field, is specially adapted to prevent that toys such as insect and mouse from entering within doors.

A kind of steel screen door is made up of the two halves door in the prior art, and what account for after opening the door is local many, and other are with the door and window that the plastics yarn is made, and are fragile, is not durable, and in addition, these doors all must come switch with hand, inconvenience.

The purpose of this utility model is, design a kind of easy for installation, open the door that the back is taken up an area of less, steel screen door that hand and pin all can switches.

The utility model comprises: the steel screen door that multi-disc rectangle steel yarn sheet is formed, upper and lower each chute, left and right each frame groove, respectively there is a shield front and back of chute, be equipped with the open the door key and the key of closing the door on the one frame groove, switch door line passes fixture, deflecting roller A on take-up pulley, deflecting roller A, deflecting roller B, the steel yarn sheet successively, gets back to take-up pulley, and fixture can move in chute; Also have two prisms up and down in addition, two of every prism has a mounting plate respectively, and prism rotates in the mounting plate at two ends, and mounting plate is released to both sides, and button on the wall; Chute, shield are fixed on the mounting plate, and the frame groove inserts in the slit of mounting plate and wall; Except that being installed with switching line, also being installed with and turning to backguy on the fixture, turn to backguy one to terminate at and the turning on the spring of the mounting plate of deflecting roller B homonymy, the other end is enclosed within (when door was closed, this node just arrived deflecting roller A place) on the switching line; Take-up pulley also is fixed with two lines in addition, the coiling of a line up time, and an other line is oppositely coiling then, and wherein a line connects the key of closing the door, and another line connects back-moving spring; The key that opens the door all has tooth with the key of closing the door, and can block mutually.

If the utility model is used for the wide door of 80cm: during the steel screen door standard-sized sheet,, promptly laterally accounting for 1/3, so vertically only accounting for 1/20 laterally or on vertical only accounting for 1/3 to 1/20 or 1/20 to 1/3 of gate-width, on the contrary also identical, relatively save the space; When mounted, prism is rotated in the mounting plate at two ends, allow mounting plate release to both sides, detain on the wall, other annex then is installed on the mounting plate, thereby does not need to hole on the wall, and installation and removal are all more convenient; The key of closing the door of the present utility model adopts pull-down and button respectively with the key that opens the door, and all installs in the door outdoors, so all can open the door and close the door with hand or pin.The utility model also can be used on the window.

Form steel screen door by 6 rectangle steel yarn sheets 3, its upper and lower each parts are identical, and symmetry is installed, below only explain with top.

Respectively there are a shield 1 and 16 in the front and back of upper hopper chute 11, be equipped with the open the door key 5 and the key 4 of closing the door on the frame groove 2, the fixture 13(fixture 13 that switch door line 10 passes take-up pulley 18, deflecting

roller

14,20,6 steel yarn sheet upper right corner of deflecting roller successively is constant on the position on the switch door line 10), deflecting roller 14, get back to take-up pulley 18, form closed circuit; Each fixture 13 can move in chute 11; Also have two of one six prism 12, six prisms 12 to have a mounting plate 8, six prisms 12 in the mounting plate 8 at two ends, to rotate respectively in addition, mounting plate 8 is released to both sides, button on the wall, mounting plate 8 is more slightly made by the one side of metope, to increase the frictional force of it and wall; Chute 11 two ends are screwed on fixed head 8, and shield 1 and 16 is screwed on mounting plate 8, and frame groove 2 inserts in the slit of mounting plate 8 and wall; Except that being installed with switching line 10, turn to handle 15 also to be installed with to turn to backguy 9, turn to handle 15 to be fixed on the square axis on it on the fixture 13, maximum can be revolved and be turn 90 degrees; Turn to backguy 9 one terminations be fixed on the mounting plate 8, with the turning on the spring 6 of deflecting roller 20 homonymies, the other end is enclosed within (when door was closed, this node just arrived deflecting roller 14 places) on the switching line 10; Take-up pulley 18 also is fixed with

backguy

17 and 19 in addition, backguy 17 clockwise around, outlet is connected on the back-moving spring 7,19 inverse times of backguy around, outlet is connected on the key of closing the door; The key that opens the door all has tooth with the key of closing the door, and can block mutually.

Steel screen door has two kinds of mounting meanss:

(1) if when steel screen door is contained in plate door and security door middle, and during 15 centimetres of middle space width less thaies that stays, fixture 13 can be installed in the centre of each steel yarn sheet, steel yarn sheet 3 turns over Yi Xiaojiao and moves to left end when opening the door, tiltedly be stacked in shield 1 and 16, at this moment shield 1 can be identical with 16 height.
