The operation principle of the sliding-door pulley device of present embodiment is：Entire sliding-door pulley device first passes through chassis 1
Mounting hole 16 be fixedly installed in the top of sliding door door-plate, when installation, first pass through screwdriver and adjust adjusting screw 5 so that pulley
Fixed frame 33 is parallel with chassis 1, adjusting bracket 2, i.e., the angle between pulley fixed frame 33 and adjusting bracket 2 is 0, after regulating,
So that the pulley 31 of bearing pulley component 3 is fallen into the fixed rack of top, then adjusting screw 5 is adjusted so that pulley by screwdriver
Fixed frame 33 is rotated relative to shaft 4, and then the angle between chassis 1, adjusting bracket 2 becomes larger, i.e., on pulley fixed frame 33
Width between two pulleys 31 becomes larger, and when two pulleys 31 offset with the side wall of fixed rack just to be bonded, stops turning,
Sliding door can be slided by pulley 31 along sliding rail at this time, realize the push-and-pull function of sliding door.
As shown in figure 5, when rotate clockwise turn adjusting screw 5 when, the adjusting bracket 2 that is attached thereto is along screw thread to screw
The direction movement of head, the first pin 211 on adjusting bracket 2 move along the first limiting slot 12 on chassis 1, are located at simultaneously
The second pin 34 on pulley fixed frame 33 is moved along the second limiting slot 13 on chassis 1, the second pin 34 sliding, push with
The pulley fixed frame 33 of connection rotated centered on shaft 4 so that between two on pulley fixed frame 33 pulley 31
Line and the horizontal direction of adjusting bracket 2 and chassis 1 between angle increase, i.e., so that pulley fixed frame 33 on two cunnings
Width between wheel 31 becomes larger.Similarly, when rotation counterclockwise turns adjusting screw 5, the adjusting bracket 2 being attached thereto is along screw thread
Moved to the former direction far from screw terminal so that line between two pulleys 31 on pulley fixed frame 33 and adjusting bracket 2 with
And the angle between the horizontal direction of chassis 1 becomes smaller, that is, the width between two pulleys 31 on pulley fixed frame 33 is made to become
It is small.
As a result, by Fig. 1~4 it is found that by adjusting adjusting screw 5 so that the adjusting bracket 2 being threadedly coupled therewith moves, into
And drive be set to adjusting bracket 2 on bearing pulley component 3 rotated centered on shaft 4, make bearing pulley component 3 pulley 31 it
Between width increase, and offset with the inner wall of sliding rail.After tested, the sliding-door pulley device of present embodiment can realize 0-
Adjusting within the scope of 90 ° realizes the adjusting of width between two pulleys 31, is suitable for the sliding rail of various different in width, significantly
Improve practicability.It is easy to adjust by the way of threaded connection, it is easy for assemble or unload.
In addition, the chassis 1 of the sliding-door pulley device of present embodiment, adjusting bracket 2 and pulley fixed frame 33 are by stainless
Steel is made, and therefore, has preferable strength and stiffness, is hardly damaged and deforms, service life is long.And two pulleys 31 are plastics
Pulley, and center is bearing arrangement, it is firm wear-resisting, while can also effectively reduce noise.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this practicality
Novel protection domain.
