Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1 to structure embodiment illustrated in fig. 5.This pulley gear comprises roller 1, and upper groove body 5 and lower groove 6 are bonded the support of roller.Roller 1 to be carried out the constraint on position to it by the wheel shaft 15 be provided with on upper groove body 5, this wheel shaft 15 is located at the core of upper groove body 5.Upper groove body 5 there is the through hole that the second through hole 16, second through hole 16 does for establishing roller 1.In addition, upper groove body 5 is also provided with groove 9, the upper end of groove 9 is provided with manhole 17.Manhole 17 effect is that when installing pulley gear parts, protrusion 10 is by the horizontal insertion groove 9 in manhole 17 position.Lower groove 6 two ends are provided with sheet material 12, and the end on sheet material 12 is equipped with fixed screw holes 7, and fixed screw holes 7 is provided with oval screw hole 8.After oval screw hole 8 loads onto screw, when the location for fixed screw holes 7, can finely tune according to the position location of headspace to pulley gear on oval screw hole 8, with the structure making the installation of pulley gear be more suitable for installation environment.Bolt 4 combines fixing through bolt hole 13 through spring 3 and corresponding bolt hole 14.This bolt 4 lower end is for adding wealthy design, and combine closely with corresponding bolt hole 14 in upper end, upper groove body and lower groove strut by spring 3, gets up to make it unlikely separately upper groove body and lower groove constraint by bolt 4.The bottom of lower groove 6 is provided with the first through hole 11, first through hole 11 can make the bottom of upper groove body 5 flexible out.Lower groove 6 is provided with protrusion 10, when upper groove body 5 is stressed be pressed downward time, the protrusion 10 of lower groove slides along the groove 9 of upper groove body 5.Shown in Figure 4, the position relationship of groove 9 and protrusion 10.
Shown in Figure 5.Lower groove 6 is screwed, and after roller 1 set on upper groove body 5 is stressed, moves under upper groove body 5 meeting be fixedly connected with wheel shaft 15.
Upper groove body is combined by bolt and spring with lower groove, has elasticity to make whole support.Groove on described upper groove body, lower groove set by correspondence and protrusion, groove and protrusion combine, thus guide moving up and down of the upper groove body in rack elasticity limited range, make whole device possess elasticity, and then can cushioning effect be played, make door more steady and smooth in active procedure.In addition, lower groove is provided with fixing sheet material, the end on sheet material is equipped with fixed screw holes, is provided with oval screw hole between fixed screw holes.After oval screw hole loads onto screw, when the location for fixed screw holes, can finely tune according to the position location of the headspace on oval screw hole to pulley gear, with the structure making the installation of pulley gear be more suitable for installation environment.
Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
