Description

Anti-slip and anti-jumping pulley structure

Technical Field

The utility model belongs to the technical field of single-leaf push-and-pull folding door and window, specifically indicate an anticreep card prevents jumping pulley structure.

Background

At present, the assembly pulley that uses on current single fan push-and-pull folding door and window includes: the main wheel set, the auxiliary wheel set and the fixed shaft seat. The fixed axle seat is fixed at the left end or the right end in the tracks at the upper end and the lower end, the end parts of the upper end and the lower end at one side of the door and window sash are provided with a main wheel set, the upper end and the lower end at the other side are provided with an auxiliary wheel set, the top end of the main wheel set is fixedly provided with a fixed axle head matched with the fixed axle seat for use, the door and window sash can slide left and right through the pulley blocks at the upper end and the lower end, when the door and window sash slides to the end part at one side of the fixed axle seat, the auxiliary wheel set of the door and window sash is separated from the tracks, the fixed axle head rotates towards the outer side of the tracks by taking the axis of the main wheel set as an axis, the fixed axle head is clamped into the fixed axle seat simultaneously for preventing the door and window sash from being clamped, the door and window sash can be pushed and pulled left and can be opened, the outer end surface of the fixed axle head of the existing pulley block and the inner side surface of the fixed axle seat are parallel to each other, the fixed axle seat body is square, the fixed axle seat body is internally provided with a circular arc-shaped groove, the fixed axle head is similar to the shape, the opposite side is straight surface, the opposite side is a cambered surface, the radius of the cambered surface is equal to that of the arc-shaped groove in the fixed shaft seat, and the cambered surface can rotate in the fixed shaft seat; the arc-shaped surface which is matched with the arc-shaped groove of the fixed shaft seat is arranged at one end of the auxiliary wheel set, when the pulley set with the structure rotates, because the working surfaces of the fixed shaft seat and the fixed shaft head are circular arcs smaller than a semicircle, the fixed shaft seat can not well clamp the fixed shaft head, and after the auxiliary wheel set is separated from the bearing of the track, glass can incline towards the auxiliary wheel set under the action of self gravity, so that the fixed shaft head is easily pulled out from the fixed shaft seat to cause the phenomenon of releasing of the clamping, and the door and window fan can incline due to releasing of the clamping. The wider the door and window leaf is, the less the working surface of the fixed shaft seat clamped by the fixed shaft head is, the more easy the door and window leaf is to be unlocked, in order to prevent the door and window leaf from being unlocked, the support of the approach bridge needs to be added outside the track, when the fixed shaft head and the fixed shaft seat have enough contact surfaces and cannot be unlocked, the auxiliary wheel set is separated from the approach bridge, so that the door and window leaf is prevented from being outwards poured out due to the fact that the fixed shaft head and the fixed shaft seat are unlocked, but the approach bridge is an undeformable fixing piece and is fixed at the position of an outlet of the auxiliary wheel set, when each door and window leaf is opened, the radius of the auxiliary wheel set is different due to the fact that the position of the auxiliary wheel set is different, the support of the approach bridge cannot be well matched with the moving track of the auxiliary wheel set, and the door and window leaf is unsmooth to be opened. The approach bridge makes the structure become complicated and because the approach bridge often stands out more than 10 centimeters than the door and window frame, can often influence the use of door and window curtain and influence pleasing to the eye, in order to avoid using the inconvenience that the approach bridge brought and prevent the emergence of the phenomenon of releasing the card, another kind of technical scheme has been adopted to current assembly pulley: the end surface of the inner side of the fixed shaft head is designed to be an inclined plane and is crossed with the end surface of the inner side of the fixed shaft seat, when the fixed shaft head of the pulley block with the structure is translated to the position of the fixed shaft seat, before the door and window sash is rotated and opened towards the outer side, the inner side of one end, close to the auxiliary pulley group, of the fixed shaft head is clamped into the arc groove of the fixed shaft seat, so that when the door and window sash starts to rotate towards the outer side, the contact surface of the fixed shaft head and the fixed shaft seat can prevent the phenomenon of releasing, the larger the rotating angle is, the more the contact surfaces are, the phenomenon of releasing is effectively prevented, but the process that the pulley block and the fixed shaft head of the structure enter the fixed shaft seat is a forced extrusion clamping process, the sliding of the door and window sash is not smooth, the use is inconvenient, in addition, the two structures are arcs with the working surface of the fixed shaft seat smaller than a semicircle, and when the width of the door and window sash exceeds 50 cm, the two structures are easy to generate the phenomenon of releasing, resulting in the inclination of the door and window sashes; the existing door and window type needs to open a notch at the inner side of a track to enable an auxiliary wheel set to enter and exit from the notch of the track, so that the door and window sash is opened and closed, the existing main wheel set is of a two-layer pulley structure, when the door and window sash is pushed and pulled leftwards and rightwards, when the main wheel set passes through the opening of the track, a jumping phenomenon can occur, the service life of a pulley is influenced, and the use feeling is not ; in order to prevent the phenomenon of disengaging, the existing pulley block needs to be additionally provided with an approach bridge, so that the structure becomes complicated and the use of a curtain and the appearance of doors and windows are influenced; in order to prevent the phenomenon of releasing the clamping, the end surface of the inner side of the fixed shaft head and the end surface of the inner side of the fixed shaft seat are designed to be of a crossed structure, and the structure causes the sliding of the door and window sash to be unsmooth and inconvenient to use; the existing pulley block can only be applied to a door window body with the glass width not more than 50 centimeters, and the application range is narrow; the phenomenon of beating can take place for current main wheel group outside through the track opening, influences the life-span of pulley, and it is not good to use the impression.
