[0002] Against the backdrop of the booming development of the modern construction industry, elevators, as an indispensable vertical transportation tool in high-rise buildings, are of paramount importance in terms of safety and stability. Elevator shaft steel structures, with their advantages of short construction cycle, light weight, and flexible modification, are widely used in new construction projects and elevator retrofitting projects in old buildings. As the core component that bears the elevator's operating load and ensures the overall stability of the shaft, the design and performance of the elevator shaft steel structure connection structure directly determine the reliability of the elevator system. Therefore, a more reasonable and efficient elevator shaft steel structure connection structure is needed to ensure the safe and stable operation of elevators.

[0003] However, the existing elevator shaft steel structure connection structure is relatively complicated to install during use, which reduces the speed of splicing the elevator shaft steel structure, resulting in a decrease in the efficiency of the splicing of the elevator shaft steel structure and affecting the construction efficiency inside the elevator shaft. Utility Model Content

[0010] Furthermore, the support assembly includes a hollow fixing rod disposed between bracket one and bracket two. The outer wall of the hollow fixing rod has a threaded groove one, and a fixing plate is disposed on the outer wall of the hollow fixing rod. The fixing plate is threadedly connected to the hollow fixing rod through the threaded groove one. The outer wall of the hollow fixing rod has four rectangular holes, and the right side of the hollow fixing rod is fixedly connected to the fixing cylinder.

[0011] Furthermore, the mounting assembly includes a slide rod disposed within a hollow fixed rod, the right side of the slide rod extending outside the hollow fixed rod, a telescopic rod fixedly connected to the left inner wall of the hollow fixed rod, the right side of the telescopic rod being fixedly connected to the slide rod, a spring sleeved on the outer wall of the telescopic rod, and a hinge being provided on the slide rod; wherein, the slide rod is slidably connected to the hollow fixed rod and supports the hinge, the right side of the spring is fixedly connected to the slide rod, and the left side of the spring is fixedly connected to the hollow fixed rod.

[0012] Furthermore, the opening component includes several fixing holes 1 formed on the bracket 1, and several rectangular protrusions are each provided with fixing holes 2; wherein, several fixing holes 1 penetrate the bracket 1, and several fixing holes 2 respectively penetrate several rectangular protrusions.

[0013] Furthermore, the fixing component includes several elastic fixing blocks fixedly connected to the inner wall of the left side of the fixing cylinder, and anti-slip pads are fixedly connected to the sides of the several elastic fixing blocks that are close to each other; wherein, when the compression ring compresses the several elastic fixing blocks, during this process, the several elastic fixing blocks respectively drive the several anti-slip pads to move closer to each other to fix the slide rod.

[0014] Furthermore, the hinge includes a circular ring fixedly connected to the inner wall of the hollow fixed rod, and a plurality of hinge blocks 1 are fixedly connected to the outer wall of the slide rod.

The circular ring is slidably connected to the slide rod, and the plurality of hinge rods are respectively connected to the plurality of hinge blocks 2.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up an installation part, during installation, bracket two is inserted into several rectangular grooves on bracket one through several rectangular protrusions at its bottom, thus splicing the steel structure. Then, the installation part is inserted into bracket one and bracket two through fixing holes one and two. At this time, pulling the sliding rod to the right causes the sliding rod to extend the telescopic rod and spring, causing the spring to deform and generate elastic force. During this process, the sliding rod drives several fixed rods to move through several hinge blocks one. Under the action of the hinge rods on several hinge blocks two on the right side of the circular ring, several fixed rods press against several hinge rods, causing several hinge rods to rotate around their corresponding hinge blocks two as fulcrums. At this time, several hinge rods move away from each other. The hinge rods, through their hinge points with the hinge blocks, support the fixed rods, causing them to extend through the rectangular holes on the hollow fixed rods. The hollow fixed rods are then pulled to the right, bringing them into contact with the outer wall of the first bracket. The fixing plate is then rotated, moving through the threaded groove on the hollow fixed rod towards the other side of the outer wall of the first bracket. The fixing plate is then rotated to its tightest position. Through the combined action of the fixing plate and the fixed rods, the first and second brackets are secured, allowing for rapid installation, reducing the time spent working at heights, lowering safety risks, improving construction safety, shortening the construction period, and enhancing the overall safety of the shaft.

[0017] 2. By setting up a fixing part, after installation, rotating the circular plate drives the extrusion ring to rotate. At this time, the extrusion ring drives the threaded protrusion to move on the threaded groove two inside the fixing cylinder. Under the action of the threaded protrusion and the threaded groove two, the extrusion ring is forced to move into the fixing cylinder. When the extrusion ring contacts several elastic fixing blocks, it will compress the several elastic fixing blocks to produce deformation and move them closer to the slide rod. At this time, the several elastic fixing blocks respectively drive the corresponding anti-slip pads to move closer to each other and contact the slide rod, thereby fixing the position of the slide rod, ensuring that the position of the slide rod remains unchanged, ensuring a stable and reliable connection, preventing the slide rod from shaking or rotating, and improving the safety and efficiency of elevator shaft construction.

[0032] A specific application of this embodiment is as follows: In use, bracket 2 112 is inserted into bracket 111 through several rectangular protrusions 114 at its bottom into several rectangular grooves 113 on bracket 111, thereby splicing the steel structure. Then, mounting part 2 is inserted into bracket 111 and bracket 2 112 through fixing hole 1 115 and fixing hole 2 116. At this time, the sliding rod 221 is pulled to the right. The sliding rod 221 will drive the telescopic rod 222 and spring 223 to extend, thereby deforming the spring 223 and generating elastic force. During this process, the sliding rod 221 is connected by several hinge blocks 225. The movement of several fixed rods 226 causes the hinge rods 228 on the hinge blocks 227 on the right side of the circular ring 224 to press against each other. This causes the hinge rods 228 to rotate around their corresponding hinge blocks 227. The hinge rods 228 then move away from each other, supporting the fixed rods 226 through their hinge points with the hinge blocks 227. This causes the fixed rods 226 to extend through the rectangular holes on the hollow fixed rods 211. Then, the hollow fixing rod 211 is pulled to the right, causing several fixing rods 226 to contact the outer wall of bracket 111. Next, the fixing plate 213 is rotated. At this time, the fixing plate 213 moves through the threaded groove 212 on the hollow fixing rod 211 and moves towards the other outer wall of bracket 111. Then, the fixing plate 213 is rotated to its tightest position. At this point, through the combined action of the fixing plate 213 and several fixing rods 226, bracket 111 and bracket 212 are fixed. After fixing, the circular plate 315 is rotated to drive the compression ring 313 to rotate. When the compression ring 313 drives the threaded protrusion 314 to move on the threaded groove 312 inside the fixed cylinder 311, under the action of the threaded protrusion 314 and the threaded groove 312, the compression ring 313 is moved into the fixed cylinder 311. When the compression ring 313 contacts several elastic fixing blocks 316, it will compress the several elastic fixing blocks 316 to produce deformation and move closer to the slide rod 221. At this time, the several elastic fixing blocks 316 respectively drive the corresponding anti-slip pads 317 to move closer to each other and contact the slide rod 221, thereby fixing the position of the slide rod 221.
