Description

TECHNICAL FIELD

[0001] The utility model relates to an improvement of elevator ground structure, in particular to a full hidden type landing door sill assembly. BACKGROUND

[0002] The sill is installed at the lower part of the elevator door ground foundation structure, and is mainly divided into a landing door sill and a car door sill, the landing door sill is installed at the building edge of the landing door and is arranged at the bottom of the landing door for use in moving the landing door, the landing door sill is a part of the building edge below the landing door extending to the shaft space, and is used for filling the gap between the car and the building edge, the traditional landing door sill structure is mainly upwardly opened with a sliding groove, and the structure of the upper part being opened with a groove is used, and sundries are easy to enter the sliding groove, which can cause the obstruction of the door movement and easily scratch the sill and cause the deformation of the sill, therefore, the sill assembly structure needs to be improved. SUMMARY

[0003] The utility model aims at overcoming the above-mentioned insufficient in the prior art, and provides a full hidden type landing door sill assembly.

[0004] The utility model discloses a technical scheme that solves the above-mentioned problem is: landing door sill assembly includes the sill body shaped as a strip, and the sill body is longer than the door opening width of the landing door, and the sill body is shaped with a sliding groove arranged downward, and the sliding groove is arranged adjacent to the outer side edge of the sill body, and the sill body is arranged with a hidden sliding block, and the upper part of the hidden sliding block is fixed on the landing door, and the lower part of the hidden sliding block extends to the outer side of the sill body and is bent from bottom to top into the sliding groove, and the upper surface of the sill body is flush with the ground surface of the building and is arranged as a tread, and the sill body is further shaped with a fixing structure and is fixed on the shaft wall below the landing door. The sill is arranged in a sliding downward mode, the problem that sundries enter the sliding groove is avoided, the protection of the sill structure is improved, the sill body is flush with the ground of the building, the building gap is filled, the use safety is improved, the overall effect is better, the appearance effect is better, and the quality of the elevator is improved.

[0005] Further, the sill body is integrally extruded from aluminum profile, the tread is shaped with anti-skid stripes, the two side edges of the tread are shaped with blocking edges higher than the anti-skid stripes, the bottom surface and the inner surface of the sill body are arranged as mounting surfaces, the bottom surface is supported by the sill support, and the inner surface is connected with the shaft wall surface. The sill is a whole integrated aluminum profile structure, the overall weight is light, the anti-skid stripes are shaped, the blocking edges on the two sides can block the rolling of sundries to the hidden sliding block to a certain extent, and the fixing basis of the landing door sill is relatively less, and two mounting surfaces are needed.

[0006] Further, the installation surfaces are provided with installation grooves, the groove openings of the installation grooves are shaped as narrowed clamping interfaces, the end portions of the connecting pieces are clamped on the clamping interfaces and are fixedly connected with the shaft wall and the sill bracket, and the opening groove width of the installation groove at the bottom is greater than the opening groove width of the inner side surface. The clamping interface facilitates the fixation of the connecting piece, effectively improves the structural installation reliability, and the installation grooves are separately provided on the two installation surfaces to form installation structures in corresponding directions, and the connection reliability is better.

[0007] Further, the outer side groove edges of the sliding grooves are shaped as shortened avoidance edges, the shortened length of the avoidance edges corresponds to the space height of the support body through which the hidden sliding block passes, and the tail end of the hidden sliding block enters the main body space of the sliding groove upward. The avoidance edge reduces the extension length of the sliding block, improves the moving efficiency, and can reduce the deformation of the sliding block structure.

[0008] Further, the hidden sliding block extends downward close to the bottom edge of the sill body, and the adjacent distance is 2-5mm. The adjacent distance of the hidden sliding block can be set closer to reduce the gap between the car and the floor, improve the aesthetic and safety.

[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is an improvement of the landing door sill structure of the elevator, the fixed structure corresponding to the shaft wall outside the landing door can effectively improve the reliability of the landing door sill installation, the surface of the sill is a normal tread, foreign matters are not easy to enter the sliding groove, the opening door smoothness is improved, the working life of the door structure is prolonged, and the anti-impact ability is good, the problem of easy disengagement is avoided, and the ability to respond to crisis state can be improved.
