The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

The following is further described with reference to the accompanying drawings and specific examples:

as shown in fig. 1, fig. 2, fig. 3 and fig. 4, an elevator door lifter comprises a base 1 and a lifting plate 2, wherein the base 1 comprises a second plate body 13 and two first plate bodies 11, the two first plate bodies 11 are arranged on two sides of the second plate body 13 in parallel, the first plate bodies 11 and the second plate bodies 13 have height differences, the lifting plate 2 comprises a main plate 21, an end plate 23 and a threaded rod 25, the main plate 21 is positioned in a space formed by the second plate body 13 and the two first plate bodies 11, the end part is connected with the end part of the first plate body 11 through a connecting shaft, the end plate 23 is fixedly arranged below the other end part of the main plate 21 and is positioned on the outer side of the end part of the second plate body 13, the threaded rod 25 is arranged in a threaded hole 22 penetrating through the main plate 21, and the lower end of the lifting plate 2 is pressed against the second plate body 13. When needing to brake elevator door leaf, the staff places base 1 in the sill groove department of elevator, and base 1 sets up along the length direction in sill groove, specifically second plate 13 submergence sill inslot, and two first plate 11 lie flat in sill groove top, because of second plate 13 submergence sill inslot, increase the stability of base 1, avoid leading to base 1 skew because of the door leaf effect. When the second plate 13 is immersed in the sill groove, the end plate 23 is also immersed in the sill groove, so that the problem that the end plate 23 is inconvenient to insert due to the small gap between the door leaf and the sill groove is avoided, and when a worker pushes the base 1 to move to the door leaf, the end plate 23 moves in the sill groove and stretches into the lower part of the end angle of the door leaf. The staff rotates threaded rod 25, because threaded rod 25 and mainboard 21 threaded connection, and mainboard 21 and first plate body 11 swing joint force end plate 23 to rise to the end angle of lifting door leaf increases the resistance that the door leaf moved, and then makes the door leaf place steadily.

As shown in fig. 3, the width of the sill groove of the elevator manufactured by different manufacturers is 8 mm to 15 mm, in order to improve the practicability of the door lifter, the distance between the two first plate bodies 11 away from the side surfaces is set to be larger than 15 mm, and the width of the second plate body 13 is 8 mm, so that the situation that the base 1 cannot be stably mounted on the sill groove due to inconsistent sizes is avoided, and the practicability of the door lifter is improved. The distance between the two first plate bodies 11 away from each other is specifically 25 mm, and the distance is set to 25 mm to overcome the large production resistance.

As shown in fig. 3, the depth of the sill groove of the elevator manufactured by different manufacturers is 10 mm to 60 mm, in order to improve the practicability of the door lifter, the second plate 13 is arranged to be horizontal to the sill and submerged in the sill groove, meanwhile, the lower side surface of the first plate 11 is contacted with the upper side surface of the sill groove, when the lifting plate 2 lifts the elevator door leaf, the depth of the sill groove cannot influence the lifting process, the situation that the lifting plate 2 cannot lift the hoistway door due to inconsistent depths of the sill groove is avoided, and the practicability of the door lifter is enhanced.

As shown in fig. 3, the lower side of the first plate 11 is higher than the lower side of the second plate 13, and the upper side is higher than the upper side of the second plate 13, and the height difference between the first plate 11 and the second plate 13 is used to provide support for mounting the lifting plate 2 and lifting the door leaf. The end face of the first plate body 11 adjacent to the end plate 23 is provided with a first inclined surface 12, and is fixedly connected with the embedded plate 14, the upper side surface of the embedded plate 14 is provided with a second inclined surface, and the inclination angle of the second inclined surface is larger than that of the first inclined surface 12. The width of the embedded plate 14 is equal to the width of the first plate body 11, and the lower side surface is flush with the lower side surface of the first plate body 11. The inclined plane is arranged so as to resist the end angle of the elevator door leaf, and the resistance of the door leaf to movement is further increased.

As shown in fig. 1 and 4, the width of the main board 21 is smaller than or equal to the distance between the two first boards 11, and the upper side may be flush with the upper side of the first boards 11. Because the width of the main board 21 is smaller than or equal to the distance between the two first board bodies 11, that is, the width of the main board 21 is smaller than or equal to the width of the second board body 13, the end board 23 is ensured to be immersed into the sill groove, and support is provided for the end angle of the lifting door leaf.

As shown in fig. 4, the lower side of the end plate 23 is flush with the lower side of the second plate body 13, and a groove 24 is provided, the groove 24 being provided along the length direction of the main plate 21. By providing the recess 24, space is provided for the insertion of the end of the guide plate below the door leaf, avoiding the presence of the guide plate being detrimental to the end plate 23 extending below the door leaf. The end plate 23 is arranged to be of an L-shaped structure, the upper side face of the horizontal section of the end plate 23 is arranged to be of an inclined structure, and an included angle between the upper side face and the vertical section of the end plate 23 is smaller than 90 degrees, so that slipping or detachment is avoided when an elevator door leaf is lifted, the uppermost end of the inclined side face of the end plate 23 is lower than the lower side face of the first plate body 11, and the groove 24 is formed in the horizontal section of the end plate 23.
