The specific embodiment

For further understanding this practical new feature and technology contents, refer to following relevant this practical new detailed description and accompanying drawing, yet institute's accompanying drawing only provide with reference to and explanation, be not used for newly being limited originally practical.

This is practical describe described in new forward and backward be according to pulley assembly for the installation position of door and window and doorframe and window frame, not therefore and this practical new scope of restriction.

By reference to the accompanying drawings 1～3, slide assemblies 10 is arranged between door and window (not shown) and doorframe and window frame (not shown), makes door and window pass through slide assemblies 10 and slides in doorframe and window frame.Pulley assembly 10 will be by load-bearing, to be installed on door and window bottom, and then drives door and window to slide in doorframe and window frame, reaches the object of opening or closing the doors and windows, and realizes building and extraneous circulation and sealing.

Pulley assembly 10, comprising: housing 110, be arranged at the pulley 130 in housing 110, the movable device 150 being connected with housing 110 elasticity, the toggle mechanism 170 being rotatably connected with housing 110 and goods of furniture for display rather than for use 190.Goods of furniture for display rather than for use 190 is along with rotation and toggle mechanism 170 butts of toggle mechanism 170.

Housing 110 provides receiving space, to place pulley 130, movable device 150, toggle mechanism 170 and goods of furniture for display rather than for use 190.Wherein, pulley 130 will make door and window smooth and easy slip in doorframe and window frame, housing 110 has formed the receiving space parallel with doorframe and window frame, its one end sealing, the other end is also provided with opening, and then the goods of furniture for display rather than for use 190 being positioned in housing 110 making exposes outside housing 110, in movable device 150 in semi-enclosed housing 110 telescopic movable.

Toggle mechanism 170 relatively housing 110 is rotated, and during to the direction rotation of goods of furniture for display rather than for use 190, the one end that makes toggle mechanism 170 and goods of furniture for display rather than for use 190 be contained in housing 110 is connected along the direction perpendicular to doorframe and window frame, goods of furniture for display rather than for use 190 this one end in housing 110 mechanism's 170 jack-up that are struck, and then the other end that goods of furniture for display rather than for use 190 is exposed outside housing 110 is sagging.

Movable device 150 comprises elastic component 151, push rod 153 and is arranged on push rod 153 rivet 155 with elastic component 151 butts.

Movable device 150 under the effect of elastic component 151 in housing 110 telescopic movable.Specifically, elastic component 151 can be spring, and its one end connects in housing 110, and the other end joins with the rivet 155 through push rod 153, and movable in the receiving space providing at housing 110 at the compression by 155 pairs of springs of rivet and release promotion push rod 153.

Toggle mechanism 170 comprises spiral arm 171, passes the free-ended rotating shaft 173 of spiral arm 171 and be sheathed on the back-up block 175 in rotating shaft 173, and spiral arm 171 makes toggle mechanism be rotatably connected with housing by the fixed axis 111 being arranged on housing 110.

Fixed axis 111 is arranged in housing 110, and toggle mechanism 170 is rotated in housing 110, to control the telescopic movable of movable device 150 in housing 110.Back-up block 175 is sheathed on the free end of spiral arm 173 by rotating shaft 173, user can control by back-up block 175 slip of door and window.

When slide assemblies 10 slides, push rod 153 makes rivet 155 block spiral arm 171 by the elastic force of elastic component 151.

Under the elastic force effect of elastic component 151, during door and window, spiral arm 171 cannot rotate, and elastic component 151 promotes rivet 155 to the fixed end of spiral arm 171, and then blocks spiral arm 171, and spiral arm 171 is in the lock state.

Further, the fixed end of spiral arm 171 radially arranges the first cam 177 along rotating shaft 173, rivet 155 blocks the first cam 177 and makes spiral arm 171 locking, will guarantee parallel between door and window and doorframe and window frame, and then has guaranteed that door and window can smooth and easy push-and-pull in doorframe and window frame.

In spiral arm 171, the fixed end of rotation is along one end butt that the second cam 179, the second cams 179 and goods of furniture for display rather than for use 190 are axially set of rotating shaft 173.

The position of the fixed end of spiral arm 171 and goods of furniture for display rather than for use 190 butts will arrange the second cam 179, along the axial setting of rotating shaft 173, and then will be by one end of the second cam 179 jack-up goods of furniture for display rather than for uses 190 while making the fixed end of spiral arm 171 and goods of furniture for display rather than for use 190 butt.

Goods of furniture for display rather than for use 190 one end bend downwards, for hook-shaped, during with one end at spiral arm 171 jack-up goods of furniture for display rather than for uses 190, to pin slide assemblies 10.

This pulley assembly 10 also comprises connecting rod 50, and slide assemblies 10 quantity are a plurality of, and interconnects by connecting rod 50.

For making door and window steadily, slide in doorframe and window frame swimmingly, pulley assembly 10 has also comprised connecting rod 50, and the quantity of slide assemblies 10 is also a plurality of, by connecting rod 50, connects in turn.

Adopt pulley assembly of the present utility model, by the pulley in slide assemblies, make door and window be able to smooth and easy push-and-pull.

As known by the technical knowledge, the above embodiment can realize by other the embodiment that does not depart from its Spirit Essence or essential feature, therefore can not therefore be interpreted as the restriction to the utility model the scope of the claims.Therefore, above-mentioned disclosed specific embodiment, for the person of ordinary skill of the art; all just illustrate; can also have some distortion, be not only to have, and the change within the scope of the utility model of place or in equivalency range all belongs to protection domain of the present utility model.
