Described a kind of turnover door, it further designs and is, described driver element comprises gear and some friction pulleys, described gear is fixedly connected on the described supporting station, the one end side surface is provided with power shaft, its bilateral symmetry horizontal distribution has some gear output shafts, and described friction pulley is fixedly connected with the both sides that are symmetrically distributed in gear with described gear output shaft.
Described a kind of turnover door, it further designs and is, be provided with the gathering sill corresponding with described gear in the described guide rail, the gathering sill bilateral symmetry is provided with two frictional grooves, described friction pulley places the corresponding frictional groove frictional groove that is in transmission connection, and slides along the table top of supporting station thereby promote guide rail.
Described a kind of turnover door, it further designs and is, described frictional groove comprises the upper rubbing surface that is positioned at guide rail top and the lower rubbing surface that is positioned at the guide rail bottom, and the described some friction pulley parts of this frictional groove that place are connected with upper rubbing surface contact, and part is connected with lower rubbing surface contact.
Described a kind of turnover door, it further designs and is that two friction pulleys that are symmetrically distributed in the gear both sides are one group, and described friction pulley has five groups, wherein two groups of friction pulleys are connected with described upper rubbing surface contact, and its excess-three group friction pulley is connected with lower rubbing surface contact.
The utility model slides by the frictional force drives guide rail between the rubbing surface in some groups of friction pulleys and the guide rail, thereby drives lifting pin with connecting rod and door body jacking upset, does not need the relatively high power motor can realize steadily that the unlatching of turnover door is with closed.

The specific embodiment
Below in conjunction with Figure of description and specific embodiment the utility model is further specified.
The contrast Figure of description, this turnover door comprises a body 1, doorframe 2 and two connecting rods 3, one end of two connecting rods 3 is fixedly connected with a side of door body 1 respectively, and the other end of connecting rod 3 is hinged with doorframe 2 respectively, and this turnover door also comprises lifting pin 4, guide rail 5, supporting station 6 and driver element 7; Supporting station is fixedly connected with doorframe one side by a fixed support 61, and an end of this supporting station is higher than the other end; Lifting pin 4 one ends and connecting rod 3 middle parts are hinged, and the other end and guide rail 5 are hinged, and guide rail 5 is slidingly arranged on the supporting station, and driver element 7 drives with guide rail 5 and is connected.
In conjunction with Fig. 5-Fig. 6, driver element comprises gear 71 and ten friction pulleys 72, gear 71 is fixedly connected on the supporting station 6, the one end side surface is provided with power shaft, its bilateral symmetry horizontal distribution has ten gear output shafts, its inside is transferred to each friction pulley by gear 73 with the driving force of external motor, and friction pulley is fixedly connected with the both sides that are symmetrically distributed in gear with gear output shaft.Be provided with in the guide rail 5 and the supporting station 6 relative gathering sill 52 of transmission case 71 that cogs, gathering sill 52 bilateral symmetry are provided with two frictional grooves 53, the lower rubbing surface 532 that frictional groove 53 comprises the upper rubbing surface 531 that is positioned at guide rail top and is positioned at guide rail 5 bottoms.This friction pulley 72 is connected with frictional groove 53 contacts.Two friction pulleys 72 that are symmetrically distributed in gear 72 both sides are one group, and ten friction pulleys namely are divided into five groups, are evenly distributed on gear center line both sides, and wherein two groups of friction pulleys are upper friction pulley 72b, are connected with upper rubbing surface 531 contacts; Its excess-three group friction pulley is lower friction pulley 72a, is connected with lower rubbing surface 532 contacts; In actual the use, for the stability that obtains best transmission efficiency and guarantee transmission, can adopt to be less than or more than five groups friction pulley.
