Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a high regulation structure of wheelset under 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 and locking 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 by the adjusting and locking device, so that sliding groove plates 9 arranged at two sides of the movable plate 3 slide up and down along sliding grooves 21 in the fixed seat 2, and the height of the guide wheel 4 is adjusted; the adjusting and locking 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 way, 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; the eccentric wheel 6 comprises an eccentric table 61 and a positioning table 62, an eccentric shaft 7 is arranged at one end of the eccentric table 61, and the eccentric shaft 7 is clamped in the adjusting hole 51; the positioning table 62 is semicircular, a plurality of positioning teeth 621 are arranged on the outer cylindrical surface of the positioning table, and an elastic sheet 8 is clamped on the positioning groove 622 between the adjacent positioning teeth 621 to fix the eccentric wheel 6.
The movable plate 3 has a chute plate 9 clamped at both sides thereof, and the chute plate 9 can slide up and down along the chute 21 at the inner side of the fixed seat 2.
A spring 10 is arranged between the sliding chute plate 9 and the fixed seat 2, and the spring 10 generates thrust to push the sliding chute plate 9 downwards all the time.
The adjusting hole 51 is waist-shaped.
The elastic sheet 8 is in a shape of less, the elastic sheet 8 is embedded in a clamping groove 22 in the fixed seat 2, and the elastic sheet 8 protrudes out of the clamping groove 22.
One end of the positioning table 62 is provided with a cross-shaped rotating table 11, and the cross-shaped rotating table 11 is clamped in the rotating hole 23 at one end of the fixed seat 2.
The working principle is as follows: before the installation, the sliding groove plates arranged on two sides of the movable plate are adjusted to slide upwards along the sliding grooves in the fixing seat, so that the guide wheels arranged in the movable plate move upwards together, and the guide wheels retract to the innermost position, thereby reducing the overall installation height of the cabinet door. At the moment, the cabinet door and the cabinet body are in a parallel height state, the cabinet door is lifted upwards, and the top end of the cabinet door is inserted into the upper track. Because the cabinet door is the parallel state rather than the tilt state with the cabinet body, the width of above cabinet need not to widen, has avoided the tradition to widen the upper rail and has made the cabinet door take place easily in the use because of not hard up the noise of operation that sends.
After the cabinet door is in butt joint with the upper rail, a user can rotate the cross rotating table on one side of the eccentric wheel through a special tool to drive the eccentric wheel to fixedly rotate in the adjusting hole, and the rotating motion of the eccentric wheel is converted into the linear up-and-down motion of the movable plate. After the guide wheel is adjusted to a proper height, the elastic sheet is clamped in the positioning groove between the adjacent positioning teeth to fix the eccentric wheel, so that the height of the guide wheel is locked. Therefore, the lower wheel set in the scheme can reduce the requirement on the size progress of the cabinet door and the cabinet body, further reduce the installation difficulty and improve the installation efficiency.
Compare with wheelset under the tradition art string sliding door, the utility model discloses well regulative mode is more simple reliable, and does not need the installer to lift the door plant and install wheelset down in the accommodation process, reduces the installation operation degree of difficulty, also need not the people and mostly coordinates the installation, reduces the degree of difficulty of installation and debugging, promotes installation and debugging work efficiency, so can extensively use widely.
The above-mentioned embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the scope of the present invention.
