In a kind of preferred embodiment of the chart drum provided at the utility model, described coil paper cylindrical shell also comprises base and face shield, described coil paper support tube side is fixedly arranged on described base, described face shield and described base engagement arrange formation receiving space, and described coil paper support tube and described worm gear are all contained in described coil paper cylindrical shell.
In a kind of preferred embodiment of the chart drum provided at the utility model, described worm screw comprises worm-drive parts and worm screw handle, described worm-drive parts and described worm gear are arranged, and are contained in described coil paper cylindrical shell, and described worm screw handle is connected with described worm-drive parts.
In a kind of preferred embodiment of the chart drum provided at the utility model, described chart drum adopts resin material or metal material to make.
Compared to prior art, chart drum of the present utility model adopts worm and gear principle, utilize worm screw driving link and worm gear follower, transmit the motion between two alternating axis and power, the deceleration had by worm-and-wheel gear, transmission agency, and the characteristic of stable drive is applied to chart drum, allow coil paper user get paper in right amount according to use amount, avoid the waste that chart drum Free-rolling brings, reduce the waste of toilet paper.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the outside drawing of chart drum one preferred embodiment that the utility model provides;
Fig. 2 is the internal structure schematic diagram of chart drum shown in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1 and Fig. 2, wherein Fig. 1 is the outside drawing of chart drum one preferred embodiment that the utility model provides, and Fig. 2 is the internal structure schematic diagram of chart drum shown in Fig. 1.
Described chart drum 1 adopts resin material or metal material to make, and comprises coil paper cylindrical shell 11 and worm-and-wheel gear 12.
Described coil paper cylindrical shell 11 comprises the coil paper support tube 111 of axial rotation, base 112 and face shield 113.Described coil paper support tube 111 is fixedly arranged on described base 112, and described face shield 113 is equipped with formation receiving space with described base 111, and described coil paper support tube 111 is contained in the receiving space of described coil paper cylindrical shell 11.
Described worm-and-wheel gear 12 comprises worm gear 121, worm screw 122 and worm gear back shaft 123.Described worm screw 122 arranges with described worm gear 121 in axle vertical direction and engages each other and is in transmission connection, and described worm gear 121 is connected with described worm gear back shaft 123.Described worm gear 121 and described worm gear back shaft 123 are in transmission connection in described coil paper support tube 111 cental axial position, are in transmission connection with described coil paper support tube 111 and described worm gear 121, and described coil paper support tube 111 is with described worm gear back shaft 123 synchronous axial system.Described worm gear 121 is contained in described coil paper cylindrical shell 111.
Described worm screw 122 comprises worm-drive parts 1221 and worm screw handle 1222.Described worm-drive parts 1221 are equipped with described worm gear 121, and are contained in described coil paper cylindrical shell 111, and described worm screw handle 1222 is connected with described worm-drive parts 1221.
