The specific embodiment

See also Fig. 1 and shown in Figure 5, the adjustment structure of limit switch of the present invention mainly is to be combined on the rolling door transmission mechanism.

Wherein the rolling door transmission mechanism includes fixed disk 1, CD-ROM drive motor 2, clutch switch 3, limit switch 4 and driving-disc 5, wherein fixed disk 1 inboard is provided with driving-disc 5, also be provided with CD-ROM drive motor 2 and clutch switch 3 on the fixed disk 1, described CD-ROM drive motor 2 is limit controlling organization to be opened in rolling door door position and the organization's integration of rolling door clutch switching controls is a transmission mechanism; The gear train that is provided with on the driving-disc 5 rotates and control limit switch 4 starts by gear.

And as shown in Figure 6, the present invention utilizes adjustment structure 6 to adjust limit switches 4 to make rolling door door position be controlled at optimum state, on fixed disk 1, be provided with two axles 11, be connected with gear train 12 on the wheel shaft 11, two gear trains 12 mesh with the gear 51 of driving-disc 5, and described gear 51 is provided in a side of on the driving-disc 5.

See also Fig. 1 to Fig. 4 with shown in Figure 6 about adjusting structure 6 structures, the adjustment structure of limit switch of the present invention mainly is that the adjustment structure 6 by at least one group touches adjustment with limit switch 4, described adjustment structure 6 includes members such as pedestal 61, worm gear axis body 62, Location resilient piece 63, limit cam bit 64 and loam cake 65, and wherein driving-disc 5 set gears 51 are located at contiguous two groups of limit switch 4 places on the fixed disk 1.Pedestal 61 centers of wherein adjusting structure 6 are provided with axle bed 611, and pedestal 61 1 sides are offered a loose slot 613, one sides and had pedestal 614 and can be provided with for worm gear axis body 62.

Described worm gear axis body 62 is to be placed on the pedestal 614 of pedestal 61 with its two ends to be pivoted, described worm gear axis body 62 includes structures such as axle center 621 and worm gear 622, be located at a plurality of grooves 623 that end surely of worm gear 622 lateral surfaces, one is located at the Location resilient piece 63 in the pedestal 61, it is to contact with the groove 623 that ends surely on the worm gear 622, and can the worm gear axis body after rotating 62 is fixing, and worm gear 622 parts are protruded in pedestal 61 outsides, rotate so that adjust worm gear axis body 62.

The axle bed 611 of said base 61 is limit cam bit 64 to be arranged for secure bond, this limit cam bit 64 is fixed on the axle bed 611 for combination, its peripheral part is provided with tooth portion 641, its opposite side with respect to tooth portion 641 is extended with a limit control strip 642, when 64 combinations of limit cam bit are fixed on the axle bed 611, described tooth portion 641 is axle center 621 engagements with worm gear axis body 62, and limit control strip 642 is for protruding out among loose slot 613.

After said modules is all assembled the location one by one, for being fixed by loam cake 65.

See also Fig. 3, Fig. 5 and shown in Figure 6 again, described gear train 12 is with the rim gear wheel 121 and gear 51 engagements of periphery, and gear train 12 surfaces are provided with inner circular tooth 122, can be for being meshing with each other with inner circular tooth 612 (see figure 2)s of adjusting on structure 6 pedestals 61 lateral surfaces.Adjusting structure 6 is that axle is located on the wheel shaft 11, and is fixed on the wheel shaft 11 by an elastic parts 66 and an enclosing cover 67 and a fastener 68.

When rolling door door position limit switch 4 can't provide accurately door position locating effect, then must utilize the manual mode adjustment, and general method of adjustment must be dismantled more spare part and operation in small space, not only time-consuming and the maintenance on also not convenient, the present invention utilizes inner circular tooth 122 engagements of adjusting the set inner circular tooth 612 of structure 6 pedestals 61 and gear train 12, when rotating base 61, it is to drive limit cam bit 64 by inner circular tooth 612 to rotate, by the rotation of limit cam bit 64 and then drive limit control strip 642 and do angular displacement and move, in case after 642 starts of limit control strip, then adjust and control limit switch 4, utilize aforesaid way to adjust limit switch 4 and be a kind of coarse adjustment structure than wide-angle.

The pattern of another kind of fine setting limit switch 4 then adjusts for the worm gear 622 that utilizes part to be located at the worm gear axis body 62 of pedestal 61 outsides, when with manual mode fine setting worm gear 622, its axle center 621 is to rotate in the lump, promptly drive 64 rotations of limit cam bit with the tooth portion 641 of axle center 621 engagements, limit control strip 642 is also done angular turn simultaneously, because the angle of worm gear axis body 62 adjustment is less, therefore can implement fine setting to limit switch 4.

In addition, be among ending groove 623 surely, to give fixed bit after worm gear axis body 62 rotates by Location resilient piece 63 elasticity clips, make worm gear axis body 62 after adjustment, be restricted the location.

By utilizing the coarse adjustment of adjusting structure 6, the rotation of fine setting control limit switch 4, and then control touching of limit cam bit 64 and limit switch 4, and the adjustment control of adjusting structure 6 is simple and easy, disconnect assembly can be finished the adjustment to limit switch easily one by one, and the adjustment of collocation coarse adjustment and fine setting control, limit switch 4 can be adjusted to best state of a control.

More than explanation is just illustrative for the purpose of the present invention, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present invention.
