As a preferable scheme: the driving block is also sleeved with a transmission sleeve, and the transmission sleeve is positioned at the gap between the roller and the driving block.

As a preferable scheme: and a plurality of screw holes are formed in the outer circumference of the transmission sleeve at intervals, fastening bolts are arranged in the screw holes, and the fastening bolts are abutted to the driving block.

As a preferable scheme: the outer circumference of the transmission sleeve is further provided with a plurality of U-shaped bayonets at intervals, transmission holes are formed in the end face of the roller and correspond to the U-shaped bayonets, and transmission rods are fixed in the transmission holes.

As a preferable scheme: the length of the short shaft is smaller than the depth of the blind hole, and the length of the short shaft is larger than that of the section of the through hole with the larger cross section diameter in the stepped hole.

The utility model discloses a set up the minor axis in the roller, during hoist and mount roller, the minor axis buries in the blind hole of roller, when the roller is aligned with the position of drive block, pulls out the minor axis from the blind hole through the screw rod that runs through the drive block for half the minor axis sets up in the blind hole, and half sets up in the shoulder hole of drive block, makes the roller realize being connected with the drive block, and such structrual installation is more convenient, moves more stably.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The broken shaft connecting mechanism shown in fig. 1 to 3 comprises a roller 1, a driving block 2, a screw 5 and a nut 6, wherein blind holes 11 are formed in two ends of the roller 1, short shafts 3 are arranged in the blind holes 11, stepped holes are formed in the driving block 2, the length of each short shaft 3 is smaller than the depth of each blind hole 11, and the length of each short shaft 3 is larger than that of a section of through hole with a larger cross section diameter in each stepped hole; can make the minor axis bury completely in the blind hole like this before the roller installation, do not influence the hoist and mount location, after the roller installation is accomplished, the minor axis is half to be set up in the blind hole, and half sets up in the shoulder hole of drive block, and the roller is connected more stably, is difficult for the pine to take off.

One end of the screw rod 5 penetrates through the stepped hole and then is in threaded connection with the short shaft 3, a threaded hole is formed in the end portion of the short shaft 3 and is connected with the threaded hole, the nut 6 is in threaded connection with the other end of the screw rod 5, the nut 6 is screwed with the screw rod 5, the nut 6 is enabled to abut against the end face of the outer side of the driving block 2, and the short shaft 3 abuts against the stepped face of the stepped hole.
