The specific embodiment

Specific embodiment below in conjunction with accompanying drawing further specifies the utility model.(but not being restriction) to the utility model.

The utility model is the improvement of on the structure of existing door lifter, carrying out, and like Fig. 1-10 structural representation, the utility model 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 gear diverter 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, and on-of pin one end is a sleeve pipe 15, establishes 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, and the interior empty capsid of top shell 4 leans against on the one side of driven wheel, and the another side roof pressure of driven wheel an end of back-moving spring 26; Back-moving spring 26 is enclosed within outside driving shaft and the hollow sleeve 9, and the other end roof pressure of back-moving spring 26 is on the shell of gear diverter 2.

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, connect through grub screw fixing, 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; Like plush copper 20); And driven wheel 16 towards upper mounted shape of plush copper corresponding 2 with upper groove; (present embodiment is established corresponding 4 grooves; Like upper groove 21 of driven wheel), each plush copper can be inserted in corresponding each groove of driven wheel one side, and shell 4 cover caps in top are peripheral in hollow sleeve one end plush copper.
