Description

Technical Field

[0001] The utility model relates to an improvement of the internal structure of an elevator car, in particular to a lining plate type control box. Background Art

[0002] The elevator car is a spatial structure formed by the car walls on all sides. With the development of structural design, the thickness of the plates used in the car walls has gradually decreased, reducing the weight of the car. At present, plates with a thickness of less than 2mm can meet the strength requirements of the car walls. However, an operating box needs to be installed on the car. The operating box has floor buttons and integrated electrical devices. Due to strength requirements, the operating box has not yet used plates with a thickness of less than 2mm. Therefore, due to the difference in thickness, the radius of the bending angle of the thicker plate will be larger than that of the thinner plate. Therefore, there will be obvious visual differences after installation, and it is easy to produce large gaps, which have a certain impact on the closedness of the car. Therefore, the operating box structure needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a lining plate type control box.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is as follows: the control box includes a bottom box, a panel and a lining plate, the bottom box and the panel are combined to form the main structure of the control box, the electrical equipment is installed on the inner side of the main structure of the control box, the panel is provided with a functional opening, and a lining plate is also provided in parallel on the inner surface of the panel, the lining plate is tightly and fixedly connected to the panel, and a functional opening is also provided on the lining plate, and the side of the lining plate facing the inside of the control box is the base surface for installing the electrical components. The bottom box of the control box is an electrical space enclosing structure, and the panel is a structure facing the inside of the car. Buttons and other working devices are mainly installed on the panel. The panel and the lining plate are combined to form a reliable front surface structure, which can provide a reliable foundation for the installation of electrical devices, and the panel can be made of thinner plates alone to achieve the same processing technology as the car wall, realizing a better integrated feeling. The lining plate enhances the strength of the panel, and more buttons can be installed, making it suitable for use in high-rise buildings.

[0005] Furthermore, the panel is bent from sheet material of the same thickness as the car wall, while the lining is made from sheet material thicker than 0.8 mm. The lining and panel are fixed together by welding or gluing. The panel can be processed in tandem with the car wall, improving processing efficiency. The lining is made from more easily processed sheet material, enhancing structural strength. Different sheet materials can be used for both, achieving a better structural combination.

[0006] Furthermore, the lining plate has a locating hem formed on its side, which serves as a side mounting limit for electrical components. Multiple fixing studs are also connected to the lining plate's surface, regularly spaced along the sides of the functional opening. The locating hem acts as a limiter, preventing electrical components from moving beyond a safe position and improving electrical safety. Since the lining plate is a separate structure, surface quality is not critical, allowing for direct installation of fixing studs, facilitating the installation of electrical components.

[0007] Furthermore, the bottom box and the panel are both provided with short and long folds, and the short and long folds of the two are arranged to align with each other. The combination of the long and short folds can balance the blanking lengths of the two, reduce large variations in the blanking process, facilitate production, and improve material utilization.

[0008] Furthermore, the top and bottom ends of the base box are each provided with a sealing head, which encloses the interior space of the control box and is also provided with a threading hole, through which the wires of the electrical components are connected to the outside of the control box. The sealing head is a space-enclosing structure at the end, which can provide protection, and the threading hole is used to pass the wires.

[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is an improvement on the structure of the elevator control box, which improves the integrity of the control box and the car wall, improves the surface quality, and can increase the structural strength, avoid the problem of deformation of the control box, and improve the quality of the elevator.
