Description

Semi-automatic roller-type curtain

The utility model is the semi-automatic Scroll curtain that belongs to home-use article, and it is a kind of formula that hangs from above curtain of rolling cord with spring torsion automatically.

The kind that Scroll hangs the formula curtain from above is a lot, the operation of its hand pulling type curtain is wasted time and energy, semi-automatic roller shutter has only possesses the function of rolling cord automatically and does not have the control of the optional position of stop, and what have can make cord put down or roll up to rest on the optional position, but the detent mechanism more complicated.Such as " semi-automatic Scroll curtain " (91223323.0) of Chinese patent, curtain can be left behind automatically, manually pull-up, but do not have the control of the optional position of stop; " door and window cord automatic winding device " (92220206.0) are to control automatic winding with going barrel, still do not have stop place control; And " lifting self-rolling structured curtain frame " (92209566.3), be with manually putting down curtain, the automatic rolling up curtains of torsionspring, and with the steel ball location, but the structure more complicated.The utility model is the improvement of double automatic reel formula curtain, and employing spring automatic curtain and click are located the novel structure of combination, just can realize pulling and put down curtain and automatic rolling up curtains, and make down a curtain or a curtain rest on the optional position.

The purpose of the utility model design, be to be to overcome the deficiency that existing Scroll hangs curtain from above, adopt novel torsionspring automatic curtain and click location combining structure, be designed to the semi-automatic Scroll curtain that cord can rest on the optional position on putting down or rolling up the time and can roll automatically from the optional position, and have simple in structure light and handy, easy to use flexibly and the low advantage of cost.

Also in conjunction with the accompanying drawings project organization of the present utility model is described in detail as follows with embodiment below:

Fig. 1 is that the structure of semi-automatic Scroll curtain is always schemed;

Fig. 2 is the A-A cutaway view of semi-automatic Scroll curtain.

As shown in Figure 1, 2, this semi-automatic Scroll curtain is made up of spool, support, cord and pelmet 15.It is characterized in that having in the pipe crimping 4 of spool a right-hand member by cylindroid helical-coil torsion spring 6 to fix with the right-end openings groove of mandrel 5 is connected, left end fixes with the right bulge loop face of terminal pad 12 and is connected, the left end square hole of mandrel 5 inserts with the right-hand member of flat axle 2 fixedlys connected, the right part of flat axle 2 and the mesopore of terminal pad 12 are loosening to be passed, fixedly connected with nylon bearing 3 and be rotationally connected by bearing and terminal pad 12 in the middle part, left part is fixedlyed connected with ratchet 10, the supporting square hole of left end and left socle 1 is inserted and is solidly connected, the outer ring surface of terminal pad 12 blocks with the left end inner ring surface of left pipe close 13 and is connected, the external tooth of ratchet 10 cooperates and is fit to any location that spool rotates with the blade tooth of ratchet 11, ratchet 11 usefulness the pins of two symmetries and terminal pad 12 rivet that the spring that is rotationally connected and forms spool reverses automatic curtain and click cooperates any off-position combining structure.Described spool is by pipe crimping 4, left and right sides pipe close 13,14 and outer cover form, its plastics, the left and right sides stomidium of stainless steel or fiberglass pipe crimping 4 respectively with a left side, right plastics pipe close 13,14 periphery is fixedly connected and cover with steel or aluminium alloy outer cover, the left end inner ring surface of left side pipe close 13 blocks with the left end outer ring surface of steel terminal pad 12 and is connected, be rotationally connected by nylon bearing 3 and flat axle 2, and support by flat axle the spool left side is contacted with the right convex surface rotation of left steel bracket 1, the centre bore of right pipe close 14 is fixedlyed connected with the left end of thimble 16, right-hand member by thimble 16 is rotationally connected with the circular hole of right steel bracket 1 and the spool right-hand member is rotated with the left convex surface of right support and contacts, left part in pipe crimping spring of suitable installation reverses automatic curtain and click cooperates any off-position combining structure, and the nylon lap buckles with the bonding nylon lap buckle of seccotine and suitable and cord 7 upper ends on the pipe crimping are fastened and connected.Left and right sides steel bracket 1 is fit to be installed in the top of window frame, and the left end of the right convex surface square hole of its left socle and flat axle 2 is inserted and is solidly connected, and the left convex surface circular hole of right support and the right-hand member of thimble 16 are rotationally connected.The upper end of cord 7 is fastened and connected by the nylon lap buckle on nylon lap buckle and the pipe crimping 4, and the bagging of lower end is connected with plastics or wooden traction item 9 suits, and traction item 9 is fixedlyed connected with draw ring 8 by backguy.Pelmet 15 is installed in the top and the front of spool, is fit to cover fully spool and support, and rises and decorate and dustproof effect.

The operation of this semi-automatic Scroll curtain is as follows: draw ring 8 is left behind gently, by backguy and traction item 9 cord 7 is left behind, drive pipe crimping 4 simultaneously and rotate, and make spring 6 torsional deflections savings energy.When leaving behind the optional position, if draw ring 8 is slowly loosened, stop because of ratchet 11 pins 10 pipe crimpings of ratchets, if draw ring is loosened fast, the gear teeth that ratchet 11 is just thrown off ratchet 10 automatically then pipe crimping at the twisting force turning down automatic curtain of spring 6.Simultaneously, on cord volume, again draw ring is left behind gently and loosen slowly that then cord is slack, in case leave behind gently when loosening fast then cord again rapidly automatically on the volume in the optional position.

Behind the utility model earthquake carriage center height, two spools can be installed simultaneously to form double-deck semi-automatic Scroll curtain, two spools are fit to load onto thick material casement and thin window yarn respectively.

In a word, the semi-automatic Scroll curtain that manufactures and designs according to present embodiment just can be neatly rests on the optional position with the click structure on the formula curtain of hanging from above puts down or rolls up the time, with spring torsion structure automatic curtain.Of the present utility model simple in structure light and handy, flexible and convenient operation, and have that cost is low, the life-span long, the scope of application extensively and be convenient to mass-producted characteristic.
