When the cage without the door lock is in operation, the escape skylight is slightly opened due to vibration, and the elevator stops running due to power failure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a construction elevator skylight lock of fleing is provided, the potential safety hazard that the construction elevator skylight of fleing can not be opened by the outside after locking has been solved, the potential safety hazard that the skylight of fleing should not have locking mechanism to exist has been solved.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a construction elevator skylight lock of fleing, is including establishing the spring lock in skylight door bottom and establishing the spring lock dog at cage skylight frame, the spring lock passes through the mounting panel to be fixed in skylight door bottom, the spring lock includes lock body, spring bolt, establish in the lock body top and with the last ejector pad of spring bolt linkage, establish in the lock body below and with the lower ejector pad of spring bolt linkage, the skylight door includes roof and frame, be equipped with the through-hole that supplies the ejector pad to stretch out on the frame. The utility model discloses the principle: when the escape skylight door is opened from the outside, the upward pushing block is pushed to retract, the upward pushing block drives the spring bolt, so that the spring bolt leaves the spring lock stop block, and the escape skylight door can be opened from the outside after the spring bolt completely leaves the spring lock stop block; when the escape skylight door is opened from the inside, the lower push block is pulled to enable the lock tongue to retract, and the escape skylight door can be opened from the inside after the lock tongue completely leaves the spring lock stop block; when the escape skylight door is closed, the spring bolt is contacted with the spring lock stop block, the spring bolt retracts under the thrust action of the spring lock stop block, when the contact is stopped, the spring bolt is positioned below the spring lock stop block, and the escape skylight is opened by rebounding and locking the spring lock to complete self-locking.
As an improvement, the push-up block comprises a push rod and a fan-shaped connecting block, one end of the push rod is connected with the lock tongue through an upper pull ring, the other end of the push rod is connected with the fan-shaped connecting block, and the fan-shaped connecting block extends out of the through hole.
As an improvement, the through hole is a rectangular hole.
As an improvement, the top of the skylight door is provided with an upper handle, and the bottom of the skylight door is provided with a lower handle.
Compared with the prior art, the utility model the beneficial effect who brings is:
the external unlocking is realized through the linkage of the upper push block and the lock tongue, and the internal unlocking is realized through the lower push block and the lock tongue, so that the potential safety hazard that the construction elevator escape skylight cannot be unlocked from the outside after being locked is solved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the escape skylight door lock of the construction elevator comprises a spring lock 6 arranged at the bottom of a skylight door 2, a skylight frame 3 arranged at a skylight opening at the top of a suspension cage 1 and a spring lock stop block 8 arranged on the inner side of the skylight frame 3, wherein the skylight door 2 can be turned over and matched with the skylight frame 3 to realize door closing or door opening.
As shown in fig. 2 and 3, the skylight door 2 includes a top plate 21 and a frame 22 disposed along an edge of the top plate 21, wherein the frame 22 can cover the skylight frame 3 to prevent rainwater from entering the skylight opening; the top of roof 21 is equipped with handle 4, makes things convenient for outside personnel to open skylight door 2, the bottom of roof 21 is equipped with down handle 5, makes things convenient for inside personnel to open skylight door 2.
As shown in fig. 3 to 5, the latch 6 is fixed to the bottom of the ceiling 21 of the skylight door 2 by a mounting plate 7. The spring lock 6 comprises a lock body 61, a lock tongue 62, an upward pushing block arranged above the lock body 61 and linked with the lock tongue 62, and a downward pushing block 65 arranged below the lock body 61 and linked with the lock tongue 62, wherein the lock tongue 62 can be driven to stretch by the upward pushing block or the downward pushing block 65, so that unlocking action is realized. The latch 6 is close to the edge of the skylight door 2, the bolt 62 of the latch 6 points to the latch stop 8 at the inner side of the skylight frame 3, when the skylight door 2 is closed, the bolt 62 touches the latch stop 8 back to retract the bolt, and after the bolt 62 completely passes over the latch stop 8, the bolt 62 stretches and retracts again. Go up the ejector pad and include push rod 63 and fan-shaped connecting block 64, the one end of push rod 63 is passed through last pull ring and is connected with spring bolt 62, and the other end and the fan-shaped connecting block 64 of push rod 63 are connected, be equipped with the rectangle through-hole that supplies the ejector pad to stretch out on the frame 22, fan-shaped connecting block 64 stretches out the through-hole makes things convenient for outside personnel to press fan-shaped connecting block 64 and realizes unblanking.
The utility model discloses the principle: when the escape skylight door 2 is opened from the outside, the push-up block is pushed to retract, the push-up block drives the lock tongue 62, so that the lock tongue 62 leaves the spring lock stop 8, and the escape skylight door 2 can be opened from the outside after the lock tongue 62 completely leaves the spring lock stop 8; when the escape skylight door 2 is opened from the inside, the lower push block 65 is pulled to enable the bolt 62 to retract, and the escape skylight door 2 can be opened from the inside after the bolt 62 completely leaves the spring lock stop 8; when the escape skylight door 2 is closed, the bolt 62 is in contact with the spring lock stop dog 8, the bolt 62 retracts under the thrust action of the spring lock stop dog 8, when the contact is stopped, the bolt 62 is positioned below the spring lock stop dog 8, the spring lock 6 rebounds to lock the escape skylight to be opened, and self-locking is completed.
