[0002] Currently, the main methods for connecting and fixing the walls of home elevator cars are as follows: 1. Bolted connection: The car wall panel is connected to the car frame by metal corner brackets and bolts. The structure is simple but the installation is complicated and requires high precision in hole positioning.

[0003] 2. Snap-on connection: Adopts plastic or metal snap-on structure, which is convenient to install but has limited load-bearing capacity, is prone to loosening after long-term use, and has insufficient safety.

[0004] The above methods generally suffer from problems such as complex installation, insufficient structural rigidity, poor seismic performance, or inconvenient maintenance. In particular, home elevators have high utilization of shaft space and a small distance between the car wall and the shaft wall, making it impossible to enter this extremely narrow space to secure the car wall using conventional methods.

[0034] Please see Figure 1-10 This utility model provides a steel wire rope fixing device for connecting the car wall of a home elevator, comprising: Car wall 1, with multiple connecting parts 2 on both sides of the car wall 1, the connecting parts 2 being arranged sequentially from top to bottom along the height direction of the car wall 1; The connecting component 2 includes an upper wire hole 21, a lower wire hole 22, and a protrusion 23, wherein the protrusion 23 is located between the upper wire hole 21 and the lower wire hole 22; Tensioning component 3 is provided on car top 4, which is located above car wall 1; The steel wire rope 5 has one end connected to the tensioning component 3, and the other end of the steel wire rope 5 passes through the upper wire hole 21 and the lower wire hole 22 at the splicing point of the two car walls 1 from top to bottom, and then passes through the lower wire hole 22 and the upper wire hole 21 from bottom to top before being connected to the tensioning component 3.

[0035] Specifically, the protrusion 23 is an arc-shaped protrusion.

[0036] Specifically, both the upper threading hole 21 and the lower threading hole 22 are waistline holes.

[0037] Working principle: Several tensioning devices are installed on the car roof. At the joint between the two car walls, there are protrusions and wire holes arranged in a row from top to bottom, with a lubricating plate on each protrusion. The wire rope crosses through all the wire holes and protrusions at the car wall joint, and the ends of the wire rope are fixed to the tensioning devices. After fixing the ends of the wire rope to the tensioning devices, pressing the handle repeatedly causes the wire rope to press against each car wall due to the tensioning force at the protrusions at the car wall joint. Example 2:

[0038] See Figure 1-10 The figure shows a steel wire rope fixing device for connecting the car wall of a home elevator, provided by Embodiment 2 of this utility model. This embodiment further improves upon the above embodiments by making the following technical solutions: The tensioning component 3 includes a fixed seat 31, a ratchet 32, a stop block 33, and a handle 34. The fixed seat 31 is fixedly connected to the car top 4, and the handle 34 is movably connected to the fixed seat 31 via a rotating shaft. The steel wire rope 5 is connected to the rotating shaft, the ratchet 32 ​​is disposed on the rotating shaft, and the fixed seat 31 is provided with a stop block 33 that cooperates with the ratchet 32. The fixed seat 31 is a U-shaped fixed seat. A mounting base is installed at the joint of the two car walls. The mounting base is welded to the car top and can also be fixed to the car top with screws. In actual use, after continuously pressing the handle until the wire rope is tightened, the teeth on the ratchet are blocked by the stop block due to gravity and cannot reverse, so the car walls will be continuously pressed together and will not loosen. When the car walls become a little loose due to the elevator running for a long time, you can continue to press the handle to tighten them. To disassemble the car walls, the stop block can be manually lifted. Example 3:

[0039] See Figure 1-10 The figure shows a steel wire rope fixing device for connecting the car wall of a home elevator, provided in Embodiment 3 of this utility model. This embodiment further improves upon the above embodiments by providing the following technical solution: a lubricating plate 6 is provided on the arc-shaped protrusion. The lubricating plate reduces the friction of the steel wire rope, allowing for the application of greater clamping force.
