Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a hang lower wheelset of sliding door which characterized in that: the adjustable guide wheel device comprises a panel 1 and a fixed seat 2 arranged at the front end of the panel 1, wherein a movable plate 3 with a guide wheel 4 is embedded in the fixed seat 2, an adjusting device is arranged between the movable plate 3 and the fixed seat 2, and the movable plate 3 is driven to move up and down through the adjusting device, so that sliding groove plates 10 arranged at two sides of the movable plate 3 slide up and down along sliding grooves 23 in the fixed seat 2, and the height of the guide wheel 4 is adjusted; a locking device 9 is arranged in one side of the fixed seat 2, the locking device 9 comprises a locking plate 91 and a hanging groove 92 arranged on one side of the sliding groove plate 10, and the hanging groove 92 is arranged on the side edge of the movable plate 3; the locking plate 91 is installed in the fixed seat 2 in a swinging mode through a hinge shaft 911 arranged on the locking plate 91, a locking column 912 is arranged on the end face of the locking plate 91, the locking column 912 passes through a locking groove 22 on one side of the fixed seat 2 and protrudes out of the locking groove 22, the locking column 912 can slide left and right along the locking groove 22, a hook 913 below the inner end of the locking plate 91 is driven to be buckled or separated from a hanging groove 92, and therefore the guide wheel 4 is locked or unlocked.

The hinge shaft 911 is hinged in the hinge hole 21 at the inner end of the fixing seat 2, and the locking plate 91 is hinged with the fixing seat 2.

The locking groove 22 is arranged in a waist shape.

A spring is arranged between the locking plate 91 and the fixed seat 2, and the spring pushes the hook 913 to swing towards the locking groove 22 all the time.

The hook 913 is formed by bending the locking plate 91 in an upward inclined manner, and the upper end surface of the hanging groove 92 is in accordance with the upper end surface of the hook 913.

The hook 913 is formed by protruding the locking plate 91, the upper end face and the lower end face of the hook 913 are respectively provided with a guide inclined plane, and the hanging groove 92 is a square groove.

The adjusting device comprises a connecting plate 5 arranged at the upper end of the movable plate 3, an adjusting hole 51 is arranged in the connecting plate 5 in a penetrating manner, an eccentric wheel 6 is arranged in the adjusting hole 51, the eccentric wheel 6 is rotated, and the eccentric wheel 6 is rotatably fixed in the adjusting hole 51.
