fig. 1 is a schematic structural view of an elevator locking device of the invention;

fig. 2 is a schematic view of an elevator locking device when a locking bar is inserted into a locking hole in the present invention;

FIG. 3 is a cross-sectional view of a side panel of the present invention;

fig. 4 is an enlarged view of the structure of part a of fig. 3 in the present invention.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1 to 4, the elevator locking device comprises a locking plate 1 and a bottom plate 2, wherein a locking rod 3 for locking an elevator car on the locking plate 1 and a metal sensor 4 for sensing metal to break an elevator safety circuit are arranged on the bottom plate 2, a metal sheet 5 for sensing the metal sensor 4 is arranged at one end of the locking rod 3 far away from the locking plate 1, and a locking hole 11 for inserting the locking rod 3 is arranged on the locking plate 1.

When maintenance personnel need get into the elevator well, insert locking lever 3 in lockhole 11 of lockplate 1, just can prevent on lockplate 1 that the car from dropping and make maintenance personnel be injured with the car locking, at this moment, the sheetmetal 5 of fixing at the other end of locking lever 3 will be close to metal sensor 4, metal sensor 4 senses the safety circuit that metal 5 will break off the elevator, prevent to make the elevator operation cause the casualties of personnel because of other people's mistake touch the switch of elevator at the in-process of maintenance, withdraw from lockhole 11 with locking lever 3 after the elevator has been maintained, at this moment, metal sensor 4 is kept away from to metal sheet 5, metal sensor 4 can not respond to the metal and will reclose the safety circuit of elevator, make the elevator can normal operating.

The handle 31 for pulling the lock rod 3 by holding by hand is arranged on the lock rod 3, so that the maintenance personnel can insert the lock rod 3 into the lock hole 11 of the lock plate by only holding the handle 31 to pull the lock rod 3, and the operation is simple and convenient.

The bottom plate 2 is provided with a side plate 6, the side plate 6 is provided with a rectangular hole 61 for providing a space for the handle 31 to move in the left-right direction, and the left end and the right end of the rectangular hole 61 are provided with U-shaped holes 62 for providing a space for the handle 31 to swing in the up-down direction.

The bottom plate 2 is provided with a lock rod seat 7 for installing the lock rod 3, and the lock rod seat 7 is provided with a through hole for the lock rod 3 to pass through and guiding the lock rod 3.

The lock lever 3 is a circular lever rotatable about its central axis.

When a maintenance person pulls the handle 31 to move the handle 31 in the rectangular hole 61, the rectangular hole 61 can limit the moving space of the handle 31 in the left-right direction and further limit the moving distance of the lock rod 3, and the metal sheet 5 is prevented from colliding on the metal sensor 4 to damage the metal sensor 4 due to the fact that the distance of the pull handle 31 is too large, and the lock rod 3 can rotate around the central shaft of the lock rod 3, so that the handle 31 can swing to the lowest end of the U-shaped hole 62 to be fixed, and the lock rod 3 is prevented from moving left and right.

The side plate 6 between the two U-shaped holes 62 is provided with a first screw 63 which can extend out from the left and right side surfaces of the side plate 6 between the two U-shaped holes 62 to limit the swing of the handle 31.

When the lock rod 3 is inserted into the lock hole 11, the handle 31 is swung to stop at the lowest end of the U-shaped hole 62, the knob 64 is twisted to enable the second screw rod 65 to rotate so as to drive the first screw rod 63 meshed with the second screw rod 65, the first screw rod 63 extends out from the left end of the side plate 6 between the two ends of the U-shaped hole 62, the handle 31 of the first screw rod 63 is fixed at the lowest end of the U-shaped hole 62 to prevent the lock rod 3 from withdrawing from the lock hole 11, the handle 31 can be moved to the lowest end of the U-shaped hole 62 after the lock rod 3 withdraws from the lock hole 11, the knob 64 is twisted to enable the second screw rod 65 to rotate so as to drive the first screw rod 63 meshed with the second screw rod 65, the first screw rod 63 extends out from the right end of the side plate 6 between the two ends of the U-shaped hole 62, the handle 31 of the first screw rod 63 is fixed at the lowest end of the U-shaped hole 62, and in the process of elevator running, the lock rod 3 extends into the guide rail to enable the lock rod 3 to collide with the parts on the guide rail, causing damage to the components on the guide rail and the lock lever 3.
