Technical Field
[0001] The utility model mainly relates to the field of elevators, in particular to a linkage structure between an elevator cage door and an outer layer door. Background Art
[0002] Elevators are widely used in workshop production, construction and other fields. Elevators usually have a double-layer protection structure of elevator doors and outer doors. The outer doors and elevator doors usually require dual control structures to control the opening. The structural redundancy increases the probability of failure in harsh operating environments. At the same time, the added structure becomes a burden on the operation of the elevator, resulting in poor use effect. Utility Model Content
[0003] To address the deficiencies of the prior art, the utility model provides a linkage structure between an elevator cage door and an outer layer door, which has a simple structure and can achieve synchronous lifting of the outer layer door and the elevator door, thereby improving the stability of the elevator cage door opening.
[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:
[0005] A linkage structure between a cage door and an outer layer door of an elevator comprises an outer layer door, a mounting seat is arranged at the bottom of the outer layer door, a wedge block is hinged on the mounting seat, a torsion spring is arranged between the wedge block and the mounting seat, a recovery shell is arranged below the outer layer door, and a recovery groove is arranged in the recovery shell.
[0006] The top surface of the wedge-shaped block is a contact surface. A circular groove is arranged on the top surface of the wedge-shaped block. An elongated iron column is arranged in the circular groove.
[0007] The bottom of the wedge block is provided with a limiting platform, and when the wedge block is separated from the recovery groove, the limiting platform conflicts with the mounting seat under the elastic force of the torsion spring.
[0008] When the limiting platform is in conflict with the mounting seat, the top surface of the wedge block is at 85 degrees with the outer door.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] The utility model has a simple structure and is easy to operate, and can smoothly drive the elevator door to open through the outer door, thereby realizing synchronous opening of the outer door and the elevator door.
[0011] This device simplifies the double-door opening structure, has a lower failure rate when used in complex environments, and can ensure the smooth use of the elevator cage. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.
[0018] like Figure 1-4 As shown, the utility model discloses a linkage structure between a cage door of an elevator and a peripheral layer door, comprising an outer layer door 1, a mounting seat 2 is installed at the bottom of the outer layer door 1, the mounting seat 2 is in an "L"-shaped structure, a wedge block 3 is hinged on the mounting seat 2, and a torsion spring 4 is arranged between the wedge block 3 and the mounting seat 2. Specifically, the front end of the wedge block 3 has a slot, and a section of the torsion spring 4 is snapped into the slot to complete the fixation. The wedge block 3 includes a planar support surface at the top and an arcuate surface at the bottom, and a limiting platform 33 is provided at the arcuate surface, and the limiting platform 33 is used to contact with the top surface of the mounting seat 2, so as to position the opening angle of the wedge block 3.
[0019] A recovery shell 5 is provided below the outer door 1 , and a recovery groove 51 is provided in the recovery shell 5 . The recovery groove 51 is used to contact the bottom surface of the wedge block 3 , so that the wedge block 3 is recovered under the restriction of the recovery groove 51 as the outer door 1 descends.
[0020] Specifically, the top surface of the wedge block 3 is a contact surface, and a circular groove 31 is provided on the top surface of the wedge block 3, and a long iron column 32 is provided in the circular groove 31. The circular groove 31 serves as the installation position of the iron column 32, and the iron column 32 penetrates the circular groove 31 for installation. The iron column 32 is used to expand the bearing area of the wedge block 3, and is used to bear the bottom of the ladder door 6 to lift the ladder door 6. The provision of the iron column 32 makes the lifting and lowering action of the ladder door 6 more coherent and smooth.
[0021] The bottom of the wedge block 3 is provided with a limiting platform 33. When the wedge block 3 is separated from the recovery groove 51, the limiting platform 33 contacts the mounting seat 2 under the elastic force of the torsion spring 4. At this time, the top surface of the wedge block 3 is 85 degrees with the outer door 1. The wedge block 3 is driven up by the outer door 1. After the wedge block 3 is separated from the recovery shell 5, the wedge block 3 is driven to open under the elastic action of the torsion spring 4, and the bottom of the upper ladder door 6 is pushed to drive the ladder door 6 to open synchronously. When the outer door and the ladder door 6 need to be closed, the outer door is lowered, and the ladder door 6 is lowered under the action of gravity to complete the closing. The wedge block 3 is swung and retracted through the conflict of the recovery groove 51, and is stored in the recovery groove 51.
