Abstract
The invention discloses a lock hook structure for preventing a landing door of an elevator from falling off. The lock hook structure comprises a sill (1). A sliding groove (2) is formed in the sill (1). First sliding blocks (3) and second sliding blocks (4) are symmetrically arranged on the two sides of the sliding groove (2). Sill supporting plates (5) are arranged above the first sliding blocks (3) and the second sliding blocks (4). The car landing door (6) is arranged on the sill supporting plates (5). A fixed block (7) is arranged in the middle of the sill (1), and sill hooks (8) are arranged on the two sides of the fixed block (7). Sliding block hooks (9) matched with the sill hooks (8) are arranged on the sides of the first sliding blocks (3). By means of the lock hook structure, the problem that an elevator landing door is separated from a sill after suffering from impacts can be effectively solved, and the use safety of the elevator is improved.
Description
Technical field
The present invention relates to a kind of elevator cage, the latch hook structure that particularly a kind of anti-elevator door comes off.
Background technology
When lift car is positioned at other stops or gate is closed, layer door is being kept closed, which ensure that people, other animals or object will not enter elevator hoistways, avoid contingency, and for general elevator, its landing-door sill device is the structure that not anti-layer door comes off, although this sill component ensure that layer door runs by certain track when switch gate, but, if layer door is when being subject to external force collision, will be easy to deform and depart from sill, object, people or other animals are possible to be strayed into hoistway and accident occurs, there is certain potential safety hazard.
Summary of the invention
It is an object of the invention to, it is provided that the latch hook structure that a kind of anti-elevator door comes off.The present invention can efficiently solve the problem that elevator door departs from after being impacted with sill, improves the safety in utilization of elevator.
Technical scheme: the latch hook structure that a kind of anti-elevator door comes off, including sill, inside sill, be provided with chute, chute be symmetrically arranged on two with the first slide block and the second slide block, first slide block and the second slide block are arranged over Sill support plate, and Sill support plate is provided with car layer door；The centre of described sill is provided with fixed block, and the both sides of fixed block are provided with sill hook；The sidepiece of the first slide block is provided with the slide block hook agreed with mutually with sill hook.
In the latch hook structure that above-mentioned anti-elevator door comes off, described sill hook includes the top board being positioned at fixed block side surface upper part, has side channel below top board；Described slide block hook is the side tenon being fixed on the first slide block side, and side tenon agrees with mutually with side channel.
In the latch hook structure that aforesaid anti-elevator door comes off, the both sides of described fixed block fix through the bottom of bolt Yu sill ditch.
In the latch hook structure that aforesaid anti-elevator door comes off, described Sill support plate is provided with 4 bolts hole, and 4 bolts hole are crisscross arranged, and are provided with supporting plate bolt in bolt hole, and Sill support plate is fixed through supporting plate bolt and car layer door.
Compared with prior art, the present invention is provided with the first slide block and the second slide block in the chute of sill, the side of the first slide block is provided with slide block hook, and the middle part of sill is provided with fixed block, and the both sides of fixed block are provided with sill hook, when car layer door is closed, slide block hook agrees with mutually with sill hook, when car layer door is subject to impacting, owing to slide block hook and sill hook hook, therefore avoid car layer door upwardly away from, improve the safety in utilization of elevator.As further preferably, described sill hook includes with fixed block in top board integrally, is side channel below top board, described slide block hook is the side tenon being fixed on the first slide block side, and when car layer door is closed, side tenon inserts in side channel, simple in construction, but anti-detachment effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the partial enlarged drawing of part A in Fig. 1.
Detailed description of the invention
