Abstract
The utility model discloses a transmission system with a disposable bed sheet convenient to replace. The transmission system comprises a bed frame, an unreeling device and a rolling device. The unreeling device comprises two unreeling self-locking sleeves and two unreeling shaft sleeves, wherein a support shaft is arranged on each unreeling shaft sleeve. Each unreeling self-locking sleeve comprises a cylinder seat and a protective sleeve, the peripheral edge of each cylinder seat extends inwards to form an installing groove which is used for installation of each support shaft, and an open groove is formed in each protective sleeve. The two unreeling self-locking sleeves are shifted between a locking state and an unlocking state. When the unreeling self-locking sleeves are in the locking state, the installing grooves and the open grooves are staggered mutually. When the unreeling self-locking sleeves are in the unlocking state, the installing grooves and the open grooves are coincident. When the unreeling shaft sleeves are locked and installed, only the support shafts of the unreeling shaft sleeves need to be placed in the installing grooves, the protective sleeves are rotated, the installing grooves and the open grooves are staggered mutually, and thus locking and installation are achieved. Due to the fact that operation is easy and rapid, the purposes of saving time and improving locking efficiency are achieved.
