Description
Technical field
The utility model relates to folding door technical field, relates in particular to a kind of automatic center-of-gravity regulating pulley assembly.
Background technology
The folding door pulley assembly using in the market and door leaf be connected to gun iron link, the function that there is no automatic center-of-gravity regulating, when door leaf is installed out of plumb or door leaf bumpy motion, the deadweight meeting of door leaf produces very large moment of flexure to door leaf rotating shaft and causes rotating shaft torsional deformation, rotating shaft is moved the in the situation that of torsional deformation, rotating shaft was lost efficacy because of fatigue failure, and countershaft has great destructiveness.Thereby reduced the application life of pulley assembly, brought great inconvenience to user, on the one hand, the fatigue failure of use procedure shaft likely causes dropping of door leaf in addition, the hidden danger of having brought life to threaten to holdee.
Therefore, there is defect in prior art, needs to improve.
Utility model content
The purpose of this utility model is to provide a kind of automatic center-of-gravity regulating pulley assembly, is applied to folding door technical field, realizes pulley assembly and regulates voluntarily its center of gravity, guarantees that door leaf is vertical, is conducive to extend the application life of rotating shaft and pulley assembly; Can also solve door leaf in prior art and drop, this hidden danger of bringing life to threaten to holdee.
The technical solution of the utility model is as follows: the utility model provides a kind of automatic center-of-gravity regulating pulley assembly, comprise: mounting seat, be installed on the bearing base in described mounting seat, be installed on the plain radial bearing on described bearing base, be installed on the thrust articulated bearing on described bearing base, be installed on the several only balance wheel assemblies in described mounting seat, be installed on the track in described mounting seat, be installed on the several load-bearing pulleys on described track, rotating shaft and locking nut, described locking nut is fixed on plain radial bearing and thrust articulated bearing in described rotating shaft, the rotation center of circle of described plain radial bearing overlaps with the rotation center of circle of described thrust articulated bearing, described plain radial bearing is located at the top of described thrust articulated bearing.
The described only quantity of balance wheel assembly is more than or equal to four.
Described in each, only balance wheel assembly comprises: be installed on the only escapement installing rack in described mounting seat and be installed on the only escapement on described only escapement installing rack.
Described in each, only escapement contacts with described track medial surface.
The quantity of described load-bearing pulley is more than or equal to four.
Described rotating shaft one end is provided with the first screw thread, and the other end is provided with the second screw thread, and described locking nut locking is installed on the screw thread of described rotating shaft one end, and the described rotating shaft other end is connected with door leaf by the second screw thread.
Adopt such scheme, automatic center-of-gravity regulating pulley assembly of the present utility model, the rotation center of circle of plain radial bearing overlaps with the rotation center of circle of thrust articulated bearing, and rotating shaft be take this coincidence and is rotated center of circle and as the center of circle, do the swing of certain angle, when door leaf is installed or move, rotating shaft just be take plain radial bearing and is automatically adjusted as centre swinging, thereby reach the effect of center-of-gravity regulating, therefore, when at track, out-of-level or door leaf is installed out of plumb, this automatic center-of-gravity regulating pulley assembly can regulate vertical with door leaf rotating shaft the center of gravity of door leaf, thereby it is crooked to avoid rotating shaft to produce, assurance door leaf is vertical, be conducive to extend the application life of rotating shaft and pulley assembly, can also solve door leaf in prior art and drop, this hidden danger of bringing life to threaten to holdee.
