Abstract
The utility model relates to a back rolling elastic adjusting mechanism of a hidden screen window, which comprises a rolling cylinder in which a return torsional spring device is arranged and a rolling cylinder bracket and is characterized in that one end of the rolling cylinder is hinged with the bracket. A bearing is arranged between a center supporting rod for fixing one end of the return torsional spring device in rolling cylinder and the inner wall of the rolling cylinder. The outer end of the center supporting rod, which extends out of the rolling cylinder, is provided with a dialing wheel fixedly connected with the outer end of the center supporting rod. The inner side part of the dialing wheel is provided with a ratchet wheel-shaped slot. The ratchet wheel-shaped slot and a ratchet engaged in the ratchet wheel-shaped slot are connected to a short shaft extending into the center of the ratchet wheel-shaped slot. The short shaft is fixed to the corresponding side part of the rolling cylinder bracket. The utility model has the advantages of simple structure, convenient operation and long service life.
Description
Technical field
The utility model relates to a kind of sliding sash with disappearing screen window backrush elastic force governor motion.
Background technology
At present, the research of sliding sash with disappearing screen window there has been bibliographical information, further perfect but these technology of having announced still need.As the patent No. be 03245193.8, name is called the utility model patent of " rolling curtain type screen window driving spring front-adjustment means ", though the technology of its announcement also is to regulate screen window by driving spring elastic force, but this device construction complexity, the manufacturing cost height, each accessory is easy to wear, and this device the running on mainly be the effect that utilizes stiction, easily skid, poor reliability is so be difficult to apply.
Summary of the invention
The purpose of this utility model is to provide a kind of simple structure compactness, easy to operate sliding sash with disappearing screen window backrush elastic force governor motion.
The utility model is to realize like this, be provided with the reel and the roller stand of reduction torsion spring device in comprising, it is characterized in that: an end and the support of reel are hinged, in this spool body in order to be provided with bearing between the center pole of fixed reset torsion spring device one end and the reel inwall, the outer end that described center pole is stretched out reel is provided with the thumb wheel with its Joint, the thumb wheel inside portion is provided with ratchet shape groove, be connected on the minor axis that stretches into ratchet shape groove center with the ratchet that meshes in the ratchet shape groove, described minor axis is fixed on the respective side portion of roller stand.
During use, the turn thumb wheel, the capable groove of ratchet in its inside edge portion rotates thereupon, and then the center pole of the reduction torsion spring device of drive and thumb wheel Joint is rotated, be fixed on spring on the pole of center owing to the effect that is subjected to torsion stretches, thereby strengthened reel initial state pretension torsion, guaranteed can fully roll withdrawal after curtain stretches at work downwards; The thumb wheel that stops operating, check pawl stop the ratchet counter-rotating.
The utility model is than existing " rolling curtain type screen window driving spring front-adjustment means ", have advantages such as simple structure, cost are low, easy to operate, especially can effectively solve when utilizing spring to reset naturally traditionally may be because of the spring problem that the sliding sash with disappearing screen window backrush elastic body that causes can't operate as normal that lost efficacy.

Fig. 2 is the sectional view of Fig. 1 in the A-A position.
The specific embodiment
In comprising, the utility model is provided with the reel 1 and the roller stand 2 of reduction torsion spring device 3, it is characterized in that: an end and the support 4 of reel 1 are hinged, in this spool body in order to be provided with bearing 6 between the center pole 5 of fixed reset torsion spring device 3 one ends and reel 1 inwall, the outer end that described center pole 5 is stretched out reel 1 is provided with the thumb wheel 7 with its Joint, thumb wheel 7 inside portions are provided with ratchet shape groove 8, be connected on the minor axis 10 that stretches into ratchet shape groove 8 centers with the ratchet 9 of engagement in the ratchet shape groove 8, described minor axis 10 is fixed on the respective side portion of roller stand 2.Wherein, thumb wheel 7 outer ledge portions are provided with moving tooth 11, and its peripheral part is fixed in and offers on the over body case of support 4 in order to rotate the opening 12 of moving tooth 11; Reduction torsion spring device 3 by center pole 5, can be absorbed in that reel inwall chute 13 and the projection 14 that slides therein and an end are fixed on center pole 5 and spring 15 that the other end is fixed on the projection 14 constitutes.
During use, turn thumb wheel 7, the capable groove 8 of ratchet in its inside edge portion rotates thereupon, and then the center pole 5 of the reduction torsion spring device 3 of drive and thumb wheel 7 Joints is rotated, be fixed on spring 15 on the center pole 5 owing to the effect that is subjected to torsion stretches, thereby strengthened reel initial state pretension torsion, guaranteed can fully roll withdrawal after curtain stretches at work downwards; The thumb wheel 7 that stops operating, check pawl 9 stops the ratchets counter-rotating.
The utility model simple structure, easy to operate, long service life have bigger application value.
