Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in FIG. 1 and FIG. 2, the band saw door body time delay handle mechanism include hand (hold) lid 3, bevel gear structure I6, bevel gear structure II 8 and bevel gear seat 7, bevel gear structure I6 and bevel gear structure II 8 all set up in bevel gear seat 7, intermeshing between bevel gear structure I6 and bevel gear structure II 8.

Bevel gear structure II 8 is arranged in bevel gear seat 7 through split washer 9. As shown in FIG. 4, the bevel gear structure II 8 comprises a bevel gear II 11 and a rotating shaft II 13, the bevel gear II 11 is fixed at one end of the rotating shaft II 13, and a central threaded hole is formed in the other end of the rotating shaft II 13. Be equipped with annular recess 12 on pivot II 13, split ring 9 card is in recess 12 to realized split ring 9 and bevel gear structure II 8's connection, split ring 8 and bevel gear seat 7's a side terminal surface fixed connection simultaneously. Therefore, the split retainer ring 9 can limit the bevel gear structure II 8 in the bevel gear seat 7 and simultaneously ensure the rotation of the bevel gear structure II 8. A screw rod is arranged in a central threaded hole of the bevel gear structure II 8, and the bevel gear structure II 8 is in threaded connection with the screw rod. And when the bevel gear structure II 8 rotates, the screw rod is driven to move back and forth in the central threaded hole along the axial direction of the screw rod. The opening and closing of the band saw door body are realized in the process of the front and back stretching of the screw rod.

Bevel gear structure I6 is arranged in bevel gear seat 7 through pressing plate 5. Bevel gear structure I6 includes bevel gear I and pivot I, and the one end of pivot I is fixed with bevel gear I, and the other end center of pivot I is fixed with the arch, bevel gear I and the meshing transmission of bevel gear II 11. The outside of pivot I is equipped with clamp plate 5, and clamp plate 5 is equipped with three self-tapping screw 4 in this embodiment through the terminal surface fixed connection of several self-tapping screw 4 with bevel gear seat 7, and self-tapping screw 4 evenly sets up at interval along clamp plate 5's periphery. The pressing plate 5 can limit the position of the bevel gear I6 and simultaneously ensure the rotation of the bevel gear I6.

Bellied center is equipped with the threaded connection hole, and 5 middle parts of clamp plate are equipped with the hole, and the hole at 5 middle parts of clamp plate is passed in the arch of bevel gear structure I6 to through screw 1 and bite-block 2 and 3 fixed connection of hand (hold) lid: the center of hand (hold) lid 3 is equipped with the screw hole, screw 1 respectively with the screw hole at hand (hold) lid 3 center and bevel gear structure I6's threaded connection hole fixed connection to the fixed connection of bevel gear structure I6 and hand (hold) lid 3 has been realized.

As shown in fig. 3, the handle mechanism is provided on the band saw door body 1, and a plurality of handle mechanisms are provided at intervals in the height direction of the band saw door body 1. The use method of the handle mechanism is as follows: when the machine is stopped, the handle cover 3 is released, and the handle cover 3 is rotated in the direction shown in the figure. Because hand (hold) lid 3 and bevel gear structure I6 fixed connection, consequently hand (hold) lid 3 rotates and drives bevel gear structure I6 and rotate simultaneously. Through the meshing transmission between the bevel gear I and the bevel gear II 11, the bevel gear structure I6 rotates to drive the bevel gear structure II 8 to rotate, so that a screw in a central hole of the bevel gear structure II 8 is driven to rotate, the extension length of the screw can be changed in the rotation process of the screw, and when the screw extends out of the bevel gear structure II 8, the screw plays a role in locking a door body; when the screw rod rotates into the central hole of the bevel gear structure II 8, the locking door body is opened. When the band saw door body is opened to needs, the operator loosens the hand (hold) lid, after the hand (hold) lid rotates, need through the meshing transmission between the bevel gear, after the action such as rotation of screw rod, just can open the door body, need certain delay time to open the band saw door body after the hand (hold) lid rotates promptly, consequently shut down when the machine, loosen the hand (hold) lid after, the band saw door body can not be opened immediately, give the band saw machine certain down time, when opening the band saw door in order to guarantee, the band saw machine is in the shutdown state, operator's safety in utilization has been guaranteed.
