The specific embodiment

The present invention is further described below in conjunction with the specific embodiment of accompanying drawing.(but not being limitation of the present invention).

The present invention is the improvement of carrying out in the structure of existing door lifter, and such as Fig. 1-10 structural representation, the present invention comprises motor 1, driven wheel 16, travelling gear 13, driven gear 11, roller 14 and arrangement of clutch etc.; Described driven wheel and travelling gear engagement, travelling gear and driven gear engagement, the driven gear rotating shaft is coaxial with roller wheel shaft; Described motor 1 is located on the base 3, and motor 1 is provided with rotating shaft, this rotating shaft epitaxial end be provided with gear and with gearing reversing device beam 2 in tooth sector engagement, the tooth sector center is provided with outwardly directed driving shaft 6, driving shaft 6 is connected with arrangement of clutch.Arrangement of clutch comprises hollow sleeve 9, on-of pin 18, top shell 4, back-moving spring 26 etc.; Hollow sleeve 9 is enclosed within on the driving shaft 6, and driven wheel 16 is enclosed within on the hollow sleeve 9; The external end head of driving shaft penetrates in the open circles 22 of hollow sleeve, the external end head 12 of driving shaft is provided with positive thread, on-of pin one end is sleeve pipe 15, establish female thread and corresponding with driving shaft 6 external end head positive threads in the sleeve pipe, then both match and make the sleeve pipe 15 can be along driving shaft 6 axial precession or back-outs, top shell 4 is for being provided with the interior empty capsid of centre bore 24, the interior empty capsid of top shell 4 leans against on the one side of driven wheel, an end of back-moving spring 26 is being pressed on the another side top of driven wheel, back-moving spring 26 is enclosed within outside driving shaft and the hollow sleeve 9, and the other end of back-moving spring 26 top is pressed on the shell of gearing reversing device beam 2.

Above-mentioned hollow sleeve is provided with fixing hole 27, the corresponding vertical screw hole that is provided with on hollow sleeve fixing hole 27 and the driving shaft, be connected and fixed by grub screw, thereby hollow sleeve 9 is fixed on the driving shaft 6, hollow sleeve 9 one ends are provided with 2 above plush coppers, and (present embodiment is established 4 plush coppers; Such as plush copper 20), and driven wheel 16 towards corresponding 2 of upper mounted shape of plush copper with upper groove, (present embodiment is established 4 corresponding grooves, such as upper groove 21 of driven wheel), each plush copper can be inserted in each corresponding groove of driven wheel one side, and top shell 4 cover caps are peripheral in hollow sleeve one end plush copper.
