Abstract
The utility model relates to an automatic curtain-rolling type screen door or window, which comprises a screen rolling drum 6, a rotating shaft supporting frame 5, a rotating shaft 4 and a spring 7. The utility model is characterized in that one end of the rotating shaft 4 is provided with a ratchet wheel 2 which is matched with a detent 1 on the rotating shaft supporting frame 5; the handle position of the detent 1 is provided with a bayonet 8 which is matched with one side of a cover casing 9; one end of the detent 1 is movably connected with the rotating shaft supporting frame 5 and the middle of the detent 1 is connected with the rotating shaft supporting frame 5 by a tension spring 3. When a window screen is exchanged, the cover casing 9 is dismounted, and the ratchet wheel 2 is positioned by the detent 1 under the function of the tension spring 10. Thus the entire annihilation of the force moment of the spring 7 can be prevented, and the force moment of the spring can be regulated only by reversing the ratchet wheel 2.
Description
The utility model relates to a kind of automatic roller shutter type screen door and window.
Utility model patent CN2119488U provides a kind of roller shutter type to open and close location screen window arbitrarily, and its structure of rolling is made up of spool, rotary shaft rack, rotating shaft, spring, pipe close and spring pretension adjusting device.Because this utility model patent changes the common garden cylindricality torque spring of screen window structure of rolling into special-shaped taper torque spring, make more reasonable in the spool with the torsion that is produced.But other patented products of this utility model patent and existing market are the same to exist a shortcoming: its window screening can only disposablely use, promptly window screening after service failure, the transposing difficulty, the general user can not change voluntarily.
The purpose of this utility model is exactly the roller blind device that can be changed window screening by the user voluntarily of design.
The purpose of this utility model is achieved in that it comprises spool 6, rotary shaft rack 5, rotating shaft 4, spring 7, is characterized in that: described rotating shaft 4 one ends are provided with a ratchet 2, and this ratchet 2 matches with ratchet 1 on the rotary shaft rack 5; Handle position at ratchet 1 has a bayonet socket 8 that matches with one side of case 9; Ratchet 1 one ends and rotary shaft rack 5 link joints, middle by extension spring 3 and rotary shaft rack 5.When this installs when in running order, one side the bayonet socket that is in ratchet 18 positions of case 9 break away from ratchet 1 and ratchet 2.
Advantage of the present utility model just is: when the transposing window screening, unload lower encioser 9, ratchet 1 with ratchet 2 location, can prevent that like this moment of spring 7 from all disappearing under the effect of extension spring 3, as long as and ratchet 2 is reversed with regard to the moment of energy regulating spring 7.
Now in conjunction with the accompanying drawings and embodiments down to the utility model explanation:
Fig. 1 is the roller blind device schematic diagram of curtain;
Fig. 2 is the schematic diagram that the ratchet of locking device is decontroled state;
The roller blind device of screen door and window of the present utility model is made of spool 6, rotating shaft 4, spring 7, rotary shaft rack 5 and locking device.Described locking device by the ratchet 2 and the ratchet 1 on the rotary shaft rack 4 in this side of rotating shaft 4 one sides and be installed on ratchet 1 and rotary shaft rack 5 between extension spring 7 constitute.One end link joint of described ratchet 1 is on rotary shaft rack 5, and the other end is the handle that bayonet socket 8 is arranged.When roller blind device is in running order, one side of case 9 is in bayonet socket 8 positions, ratchet 1 is located in and ratchet 5 position that is separated, spool 6 can moving up and down and rotate with window screening, as unload lower encioser 9, the ratchet 1 that loses support with ratchet 2 interlocks, makes rotating shaft 4 keep certain moment under the effect of extension spring 3.
