Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a novel elevator door lock comprises two fixing strips 1, wherein the two fixing strips 1 are fixedly connected to the top surface of an elevator door, when the device drives the fixing strips 1 to move, the elevator door can move synchronously to achieve the effect of being opened, the number of the fixing strips 1 is two, the middle parts of the two fixing strips 1 are respectively and fixedly connected with a clamping net piece 2, the diameter value of the mesh of the clamping net piece 2 is far larger than the width value of a clamping rod 3, two sides of the clamping net piece 2 are respectively clamped at the bottom end of the clamping rod 3, the clamping rod 3 extends upwards, the top end of the clamping rod 3 is fixedly connected to the bottom surface of a rack 4, the middle part of the rack 4 is provided with a chute 5 with the same length value as the rack 4, the left end and the right end of the rack 4 are respectively and fixedly connected with a limiting block 6, the rotating ranges of a first gear 12 and a second gear 13 are limited by respectively adopting, avoid moving about to the outside of rack 4, the middle part joint at the spout 5 back is in the bottom surface of telescopic link 7, the top surface fixed connection of telescopic link 7 is in the one end of spring 8, and the other end fixed connection of spring 8 is at the top surface of body 9 inner chamber, the top fixedly connected with location bearing 10 of spring 8, the back fixed connection of location bearing 10 is in the front of mounting panel 11, the left and right sides of mounting panel 11 is fixed the cover respectively and is connected with first gear 12 and second gear 13, the positive middle part fixed connection of first gear 12 has triangular bar 14 to openly stretching out, the one end joint in the triangular bar 14 outside has bull stick 15, when bull stick 15 rotates, can provide synchronous pivoted effort for first gear 12 and second gear 13, be the main reason that the lift-cabin door can be opened by hand.

The first gear 12 and the second gear 13 are meshed with each other, the diameter values of the first gear 12 and the second gear 13 are equal, the bottom surfaces of the first gear 12 and the second gear 13 are meshed with the top surfaces of the two racks 4 respectively, the first gear 12 and the second gear 13 on two sides are designed to be equal in diameter value, and the bottom surfaces of the first gear 12 and the second gear 13 are meshed with the two-day racks 4, so that the second gear 13 can keep the same rotation amplitude with the first gear 12, and the two sides of the elevator door are ensured to be equal in opening distance value.

The number of the positioning bearings 10 is two, the two positioning bearings 10 are respectively and fixedly connected to the left side and the right side of the front surface of the mounting plate 11, the middle parts of the positioning bearings 10 on the two sides are on the same horizontal plane, and because the elevator door lock is in a working process, the first gear 12 and the second gear 13 are in a rotating state, through the design that the first gear 12 and the second gear 13 are respectively sleeved on the two positioning bearings 10, the positions of the first gear 12 and the second gear 13 can be limited, and the rotating effect of the first gear 12 and the second gear 13 can not be hindered.

Triangular slotted hole has been seted up to the one end that bull stick 15 is close to triangular pole 14, the size of slotted hole and the size of triangular pole 14 match each other, and the inner chamber of triangular pole 14 joint at the slotted hole, when elevator normal condition, bull stick 15 is the state of being taken off, can avoid causing the hindrance to the operation of elevator, when the elevator breaks down, can imbed the one end of bull stick 15 with triangular pole 14, at this moment when rotating bull stick 15 again, can ensure that the pivoted effort can transmit completely for first gear 12.

The bottom fixedly connected with slider at the telescopic link 7 back, the slider joint is at the middle part at the spout 5 back, and at first gear 12 and second gear 13 pivoted in-process, two racks 4 also are in the state of outside activity, through the design of seting up spout 5 in the middle part of rack 4, can utilize telescopic link 7 to come to prescribe a limit to the position of rack 4, ensure that rack 4 can be along certain orbit horizontal slip.

The piston has been cup jointed in the bottom surface activity of 9 inner chambers of body, and the upper and lower both sides of piston are fixed connection respectively at the top of telescopic link 7 and the bottom of spring 8, and under the state that the elevator normally used, joint pole 3 is not with joint net piece 2 mutual joint to under the effect of spring 8 elasticity, can upwards stimulate two racks 4 all the time, avoid influencing the normal operating of elevator, the piston is the connection carrier between telescopic link 7 and the spring 8.

The working principle is that before the elevator door opening device is used, the bottom surfaces of the fixing strips 1 on the two sides are fixed on the top surfaces of the two sides of the elevator door respectively, then the mounting plate 11 is fixed at a proper position on the top surface of the elevator door, the middle part of the mounting plate 11 is ensured to be positioned in the middle part of the elevator door, then the device can be mounted, when the elevator door fails to be opened, the triangular rod 14 is inserted into one end of the rotating rod 15, then the mounting plate 11 is pushed downwards, so that the clamping connecting rods 3 on the bottom surface of the rack 4 can be inserted into the inner cavity of the clamping net piece 2 at least two, when the rotating rod 15 is rotated, the first gear 12 and the second gear 13 can have opposite rotating effects, meanwhile, the two racks 4 on the bottom surface can synchronously move, and because the rack 4 can pull the fixing strips 1 towards the two sides under the mutual.
