Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with attached drawing and embodiment, the utility model is further described.
As shown in Figure 1-3, a kind of adjustable land wheel of self-balancing hollow door of the utility model, including shell 1 and pulley bracket 2,
Pulley bracket 2 is set in shell 1, and installation is equipped with pulley assembly in pulley bracket 2.As shown in figure 5, pulley assembly includes pulley
18, central spindle 19 and plain cushion 20, plain cushion 20 is located at the two sides of pulley 18, and pulley 18 and plain cushion 20 are fixed on cunning by central spindle 19
In wheel support 2.Height adjusting bracket 3, open at one end, one end of pulley bracket 2 of height adjusting bracket 3 are additionally provided in shell 1
Activity is embedded in height adjusting bracket 3, sees that Fig. 4, shell 1 are respectively equipped with 4 He of Level tune hole through 1 front and rear panel of shell
Hinge hole 5, height adjusting bracket 3 are equipped with through-hole 6, and pulley bracket 2 is respectively equipped with and the Level tune hole 4 of shell 1 and hinge hole 5
Corresponding vertical sliding motion hole 7 and tilt slide hole 8 pass through the first primary and secondary between Level tune hole 4, through-hole 6 and vertical sliding motion hole 7
9 connection of nail, is connected between hinge hole 5 and tilt slide hole 8 by the second master and slave dowel 10, and the side of shell 1 is equipped with for controlling
Pulley bracket 2 is along the oblique adjusting component moved of shell 1.
When there is tilt angle on ground or ground rail, unevenness phenomenon occur, pulley bracket 2 passes through the first master and slave dowel 9
It can be moved up and down along vertical sliding motion hole 7, automatically adjust the lengthwise position of pulley bracket 2, protect hollow door and the track of bottom
Certain balance is held, hollow door detent is prevented, pushes and pulls not the problem of smoothly phenomenon.
Adjusting component includes adjusting screw 11 and nut 12, and the side of shell 1 is equipped with screw hole 13, height adjusting bracket 3
Side is equipped with movable span 14 corresponding with screw hole 13, and the inner sidewall of height adjusting bracket 3 is equipped with the fixture block for fixture nut 12
15, nut 12 is mounted between fixture block 15 and the side wall of height adjusting bracket 3, and adjusting screw 11 sequentially passes through screw hole 13 and activity
