Detailed Description

The following describes the present invention in further detail with reference to fig. 1-5.

As shown in fig. 1-5, the utility model comprises a bottom plate 1, frame plates 2 which can slide horizontally and vertically are arranged above the bottom plate 1, and a rotatable guide wheel 3 is arranged between the two frame plates 2;

the roller is of a solid structure.

In the utility model, the guide rail wheel 3 is a solid roller structure, and the solid roller has no bearing and is suitable for heavy doors and windows;

the frame plate 2 can slide horizontally and vertically, so that the positions of the guide rail wheels 3 in the horizontal and vertical directions can be adjusted, and the adjustment of the positions of the guide rail wheels 3 is realized.

The detachable of 1 upper end of bottom plate is connected with collet 4, is equipped with the guide way 5 of slope on collet 4, and the right-hand member of guide way 5 is higher than the left end, and slidable is equipped with round pin axle 6 in the

guide way

5, and 6 both ends of round pin axle run through guide way 5 and frame plate 2 fixed connection, and frame plate 2 upwards slides along guide way 5 at the horizontal slip in-process.

The collet 4 is located the position between two guide rail wheels 3, the gliding extreme position of right side guide rail wheel 3 just does not contact with collet 4, collet 4 is together fixed with bottom plate 1, when frame plate 2 carries out horizontal slip, because of selling axle 6 and frame plate 2 be fixed connection's relation, round pin axle 6 can slide along guide way 5 at horizontal slip's in-process this moment, frame plate 2 can carry out vertical slip this moment, so frame plate 2 carries out vertical slip simultaneously at horizontal slip's in-process, also be exactly that guide rail wheel 3 carries out vertical slip in horizontal slip.

But two 2 right-hand members of frame plate vertical sliding are connected with nut piece 7, and the rotatable threaded rod 8 that is connected with in 1 right side upper end of bottom plate, threaded

rod

8 and 7 threaded connection of nut piece, threaded rod 8 rotate and carry out the horizontal slip through nut piece 7 drive frame plate 2.

Two frame plate 2 right-hand members are equipped with vertical spout, are equipped with the slider in the spout, and the slider runs through spout and nut piece 7 fixed connection, carries out the pivoted in-process when threaded rod 8, and it can drive nut piece 7 and carry out the horizontally slip, thereby nut piece 7 horizontal slip drives frame plate 2 and carries out the horizontally slip.

The coaxial fixedly connected with turbine 9 of threaded rod 8, the meshing has worm 10 below turbine 9, and worm 10 and bottom plate 1 rotatable coupling, worm 10 rotate and drive threaded rod 8 through turbine 9 and rotate.

Be equipped with the patchhole on the worm 10, conveniently insert the screwdriver in the patchhole to thereby drive worm 10 rotates, thereby worm 10 rotates and drives turbine 9 and rotate, and turbine 9 worm 10 has fine auto-lock effect in addition, and threaded connection relation of threaded rod 8 and nut piece 7 in addition, thereby fine assurance nut piece 7's horizontal position.

The outer circumference cover of threaded rod 8 has

spring

11, and 11 left ends of spring and frame plate 2 right side extrusion contact, 11 right-hand members of spring and bottom plate 1 fixed connection.

We also can not set up the spout of nut piece 7 at frame plate 2, like this under spring 11's effect, spring 11 is for promoting frame plate 2 slip left side all the time, can guarantee frame plate 2's position like this, and nut piece 7 drives frame plate 2 and carries out the horizontal slip after, can guarantee frame plate 2's position, if frame plate 2 when gliding to the left side, nut piece 7 slides to the left side, under spring 11's motive force, frame plate 2 slides to the left side.

The bottom plate 1 and the bottom support 4 are fixedly connected through a fine adjustment screw 12.

Through twisting the fine setting screw 12, can change bottom plate 1 and collet 4 complex intensity to make collet 4 have certain vertical displacement, conveniently adjust the position of guide way 5 like this, then change the position of frame plate 2 motion.

In the present invention, it is preferable that the nut block 7 and the frame plate 2 are in contact with each other, and the spring 11 is used to push the frame plate 2 to slide to the left.

The utility model discloses when using, the rotation through worm 10 drives nut piece 7 and carries out horizontal slip, realizes the change of 3 levels of guide rail wheel and high position then, realizes the one-level regulation, according to actual site environment horizontal position, adjusts the high position of fine setting screw 12 about adjusting, realizes that different altitude mixture control about the site environment like this effectively realizes the level, realizes the second grade and adjusts, uses different door and window notch degree of depth, is suitable for the depth control on a large scale.

Solid construction's guide rail wheel 3 can use when playing weight door and window, and application scope is wider, and guide rail wheel 3 can realize the second grade and adjust, according to site operation environment adjustment door and window level, more is suitable for the door and window that the size height scope is wider.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
