Description

[Detailed Description of the Invention] The present invention relates to a small-sized lifting door for opening and closing irrigation channels, etc., and is characterized in that the door can be rolled up and stopped easily.

Hereinafter, the configuration of the present invention will be explained with reference to embodiment figures.

Guides 2 and 2' are provided on both sides of the rectangular frame 1 to fit the door 3, a spindle protection tube 4 is provided protruding from the center of the top surface of the frame 1, and the upper end of the spindle protection tube 4 is The winding case 5 is fixed, a spindle 6 loosely attached to the center position of the upper end of the door body 3 is provided to protrude upward from the protection tube 4 through the winding case 5, and a handle 7 is attached to the upper end of the spindle 6. fixed,
Inside the case 5, shafts 8 and 8' are installed horizontally at an upper position closer to the back and a lower position closer to the front, and a stopper plate 10 with a locking hole 9 at the center position fitted into the spindle 6 is loosely attached to the shaft 8. A stop lever 1 fixed to the stopper plate 10 together with the stop lever 1
1 protrudes toward the front of the case from a vertical hole 12 provided in the front of the case 5, and the forked rod 13 is loosely attached to the shaft 8' at the lower position of the stopper plate 10, and the locking hole 9' at the center is connected to the spindle 6. The locking plate 14 fitted into the forked rod 13 is loosely attached to the shaft 15 in the forked rod 13, and the lifting lever 16 fixed to the forked rod 13 is projected to the back of the case from the vertical hole 12' provided on the back of the case. This is to constitute a lifting door 17 with a hoisting device.

Next, the effects of the present invention will be explained with reference to embodiment figures.

The lifting door 17 with a lifting device according to the present invention locks the spindle 6 of the door body 3 with a stopper plate 10 inside the case 5, and also operates the lifting lever 16 up and down while moving the forked rod 1.
The locking plate 14 pivotably mounted in the shaft 3 engages with the spindle 6 to raise the spindle 6 little by little. When raised to , the locking hole 9' of the locking plate 14 pivoted to the shaft 15 in the forked rod 13 becomes inclined, locking the spindle 6 and lifting the spindle 6. 16, the locking plate 14 in the forked rod 13 becomes horizontal and the locking hole 9' slides downward on the outer periphery of the spindle 6, and at this time the upper stopper plate 10 tilts around the shaft 8. The spindle 6 is then locked using the locking hole 9 at the center of the stopper plate 10.

Therefore, the vertical operation of the winding lever 16 and the stopper plate 10
With the automatic locking operation, the spindle 6 can gradually rise to open the door body 3, and the opening width of the door body 3 can be freely adjusted, so that the door body 3 can be opened at once. In this case, the stopper plate 10 is held horizontally and the spindle 6 is
After releasing the lock, the door body 3 can be raised by grasping the handle 7 at the upper end, and the spindle 6 can be locked by tilting the stopper plate 10. Since the structure is simple, it can be manufactured at low cost. It is possible to achieve various remarkable effects as described above.
