Title: Structure of a wax-polishing machine

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a polishing machine, and particularly to the structure of a wax-polishing machine. 
     2. Description of the Prior Art 
     The conventional wax-polishing machines may be classified into two kinds, i.e., an electro-motive type and a pneumatic type. The two types are using electric power and a high-pressure air respectively to drive the rotors to turn; and then such turn will be transformed into a high torsion and a low speed output to actuate the polishing machine to polish the surface of a car with wax. 
     The rotation disk on the front end of the polishing machine includes a single round shaft connected pivotally with a transmission shaft; the surface of the rotation disk is usually mounted with a cloth-type-polishing member or a sponge-polishing member. The machine is driven with a high torsion and a low speed power so as to have the polishing member contacted with the car surface, and to remove wax coated on the car surface and to polish the same. 
     Since the conventional polishing machine has a single round shaft to connect pivotally with a transmission shaft, the surface of the rotation disk can rotate in one direction only; after wax is put on a car, a polishing person uses a hand to coat (in a rotary manner) wax on a car slowly; such a way of coating wax and polishing take a quite long time. 
     SUMMARY OF THE INVENTION 
     The prime object of the present invention is to provide a structure for a wax-polishing machine, in which the front end of the transmission shaft of the polishing machine is mounted with a driving gear and an inner rotation disk; the inner rotation disk is mounted in the center of an outer rotation disk, which is connected, by means of screws, with the outer edge of an inner driven gear; an idle gear is mounted between the inner driven gear and a driving gear; when the transmission shaft of the body portion rotates, the inner and outer rotation disks will be driven to rotate, and then the inner and outer sponge pieces will also rotate in different directions. 
     Another object of the present is provide a structure for a wax-polishing machine, in which the transmission shaft is mounted with a driving gear, and the outer edge of the driving gear is fixedly screwed in a center cylindrical hole of the inner rotation disk; the surface of the inner rotation disk is glued with a Velcro pad to be connected with another Velcro pad attached with a polishing sponge piece; a power can directly be transferred to the sponge piece by means of the transmission shaft. 
     Still another object of the present invention is to provide a structure for a wax-polishing machine, in which one side of the driving gear on the transmission shaft is engaged with an idle gear which is then engaged with an inner driven gear; the outer edge of the inner driven gear is connected together with an outer rotation disk by means of screws; the outer surface of the outer rotation disk is mounted with a Velcro pad to be glued with another Velcro pads on the bottom of a polishing sponge piece; the inner driven disk can transfer power to the polishing sponge piece on the outer surface. 
     A further object of the present invention is to provide a structure for a wax-polishing machine, in which the Velcro pads attached to the inner and outer rotation disks facilitate the polishing sponge pieces to mount or dismount, if necessary. 
     A still further object of the present invention is to provide a structure for a wax-polishing machine, in which two replaceable polishing sponge pieces are furnished on a detachable basis; for waxing operation, the outer sponge piece may be removed, and then the inner sponge piece can be used to rotate so as to coat wax on a car quickly. 
     Yet another object of the present invention is to provide a structure for a wax-polishing machine, in which two replaceable polishing sponge pieces are furnished on a detachable basis; for waxing operation, the inner sponge piece may be dismounted and replaced with a lower sponge piece; then, the space left with the lower sponge piece can be used for putting additional wax therein so as to supply more wax for later coating. 
     Yet still another object of the present invention is to provide a structure for a wax-polishing machine, in which two replaceable sponge pieces are furnished; for polishing operation, the inner and outer sponge pieces can rotate at different linear speed so as to finish the polishing operation rapidly.

After the driving gear  19  is screwed on the transmission shaft  13 , the power applied to the transmission shaft  13  will be transferred to the inner rotation disk  21 ; further, the power will also be transmitted to the outer rotation disk  22  via the driving gear  19 , the idle gear  18  and the inner driven gear  17  so as to provide two different output of power. 
     The inner rotation disk  21  is to be mounted on the transmission shaft  13 ; the surface of the inner driven gear  17  on the outer edge the fixed disk  15  is furnished with a plurality of thread holes  36 . The surface of the inner driven gear  17  is mounted with an outer rotation disk  22  by using a plurality of screws  43 ; the outer rotation disk  22  includes an inner disk surface  40  and an outer disk surface  41  partitioned by means of a ring-shaped plate  53 . The center of the inner disk surface  40  is furnished with a cylindrical hole  44  having a suitable diameter; the inner disk surface is furnished with a plurality of sunk screw holes  42  for receiving screws  43  upon the outer rotation disk  22  being fastened in place; the screws  43  and the inner disk surface  40  are all on a same horizontal surface. The outer disk surface  41  outside the ring-shaped plate  53  has a suitable width extended outwards. The outer disk surface  41  is glued with a Velcro pad  45  which is made of a knitted pad with a plurality of thermoplastic single threads to be cut into a plurality of tiny hooks, i.e., a piece of rug to provide a fastening function. 
     The outer rotation disk  22  is fixedly mounted on the outer edge of the inner driven gear  17 ; the center cylindrical hole  44  of the outer rotation disk  22  is used for receiving the post body  46  furnished with inner threads  47 . When the inner threads  47  of the post body  46  are mated together with the outer threads  14  of the transmission shaft  13 , the driving gear  19  will be fixedly mounted on the transmission shaft  13 . The outer edge of the inner rotation disk  21  is furnished with a ring-shaped plate  54  having a suitable height; the inner disk surface  48  of the ring-shaped plate  54  is to be glued with a round Velcro pad  49 , which is made of a knitted pad with a plurality of thermoplastic single threads to be cut into a plurality of tiny hooks, i.e., a piece of rug to provide a fastening function. 
     After all transmission parts of the polishing machine  11  are mounted on the front end of the body portion  12 , the fixed disk  15  is obviously divided into two independent disk surfaces (i.e., a Velcro pad and a round Velcro pad  45  and  49 ). The outer disk surface is mounted with a sponge piece  24  attached with a Velcro pad  51 , of which the surface is furnished with an adhesive pile to be glued together with the Velcro pad  45  furnished with tiny hooks. The inner disk surface is glued with a Velcro pad  50  attached with a sponge piece  23 ; the adhesive pile of the Velcro pad  50  is to be glued together with the Velcro pad  49  which has a tiny hook surface. The height and kind of the sponge pieces  23  and  24  attached to the inner and outer rotation disks  21  and  22  respectively are varied in accordance with the uses desired. 
     The front end of the body portion  12  of the polishing machine  11  is mounted with the transmission parts respectively. When the transmission shaft  13  has an output of low speed and a high torsion, the inner sponge piece  23  of the inner rotation disk  21  is connected together with the transmission shaft  13  by means of the post body  46  of the disk  21  so as to be driven with the transmission shaft  13 . The outer sponge piece  24  on the outer rotation disk  22  can rotate in different directions because that the outer rotation disk  22  and the outer edge of the inner driven gear  17  are connected together, and the outer surface of the inner driven gear  17  is mounted in the bearing  16  before being fixed to the fixed disk  15 , and then the driving gear  19  and the idle gear  18  are engaged with the inner rotation gear  17  so as to have the power on the transmission shaft  13  transferred to the outer rotation disk  22 .
