Description

Technical Field

[0001] This utility model relates to the field of car manufacturing technology, specifically to a quick-installation connection structure for car walls. Background Technology

[0002] In recent years, many residents living on high floors, especially the elderly, have found going up and down stairs to be a problem, leading to a growing call for the installation of elevators in old buildings. The process of installing elevators in old buildings requires the installation of shafts in the stairwells, and then the installation of elevator cars and other structures within the stairwells.

[0003] Traditional car wall connections rely on bolts and other methods. In narrow shafts with limited operating space, each hole needs to be aligned and tightened one by one. The installation process is cumbersome, time-consuming, and labor-intensive. Furthermore, the quality of bolt tightening is affected by human factors, and improper operation can easily lead to insufficient connection accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-installation connection structure for car walls, in order to solve the problems mentioned in the background art, which rely on bolts and other methods for car wall connection. In narrow shafts, the operating space is limited, and it is necessary to align the holes one by one and tighten them. The installation process is cumbersome, time-consuming, and labor-intensive. In addition, the bolt tightening quality is affected by human factors and is prone to insufficient connection accuracy due to improper operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation connection structure for car walls, including a car bottom, wherein a first car wall, a second car wall, and a third car wall are bolted to three sides of the car bottom; connecting rods are fixedly installed on both sides of the first car wall, both sides of the second car wall, and both sides of the third car wall; a connecting structure is bolted to the inner cavity of the connecting rod; and a slot is provided on one side of the connecting rod.

[0006] Preferably, a second fixing plate is fixedly installed on the top of the first car wall, the top of the second car wall, and the top of the third car wall. A first fixing hole is opened on the top of the second fixing plate, and the top of the second fixing plate is bolted to the car roof through the first fixing hole. The car wall and the car roof can be fixedly connected through the fixing hole.

[0007] Preferably, the connection structure includes a connecting block, with a first fixing plate fixedly installed at both ends of the connecting block, a second fixing hole opened in the middle of the two first fixing plates, a snap-fit ​​block fixedly connected to one side of the connecting block, and a snap-fit ​​groove opened between the connecting block and the snap-fit ​​block. The snap-fit ​​groove on the connection structure is used for limiting the movement, which allows the car walls to be fixed together.

[0008] Preferably, the inner cavity of the first fixing plate is bolted with rivets, and the first fixing plate is connected to the connecting rod by the rivets. The rivets can fix the connecting structure to the connecting rod on the car wall.

[0009] Preferably, the first car wall is connected to the slot on the second car wall via a snap-fit ​​block, and the second car wall is connected to the second car wall on the third car wall via a snap-fit ​​block.

[0010] Preferably, the connecting block, the first fixing plate, and the snap-fit ​​block are all made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by first installing the connecting structure on the connecting rod with rivets, and then by using the snap-fit ​​block on the connecting structure to snap into the slot on the car wall, the car wall can be quickly installed in a confined space in the shaft. At the same time, the connecting structure can improve the installation efficiency of workers. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figure 1-4This utility model provides a quick-installation connection structure for car walls, including a car bottom 1. The three sides of the car bottom 1 are bolted together with a first car wall 3, a second car wall 4, and a third car wall 5. Connecting rods 6 are fixedly installed on both sides of the first car wall 3, both sides of the second car wall 4, and both sides of the third car wall 5. The inner cavity of the connecting rods 6 is bolted together with a connecting structure. A slot 14 is provided on one side of the connecting rods 6. A second fixing plate 15 is fixedly installed on the top of the first car wall 3, the top of the second car wall 4, and the top of the third car wall 5. A first fixing hole 9 is provided on the top of the second fixing plate 15. The top of the second fixing plate 15 is bolted together with a car top 2 through the first fixing hole 9.

[0016] In this embodiment, the connecting structure is first installed in the connecting rods 6 on the first car wall 3, the second car wall 4, and the third car wall 5. Four connecting structures are evenly installed and fixed with rivets 7. Then, the first car wall 3 is installed on the car bottom 1 using external equipment and fixed with bolts. Then, the second car wall 4 is lifted by external equipment and then the connecting structure is engaged with the slot 14 opened in the connecting rod 6 on the second car wall 4 for locking and limiting. Then, they are installed in sequence.

[0017] Please see Figure 1-4 Furthermore, the connection structure includes a connecting block 11, with a first fixing plate 12 fixedly installed at both ends of the connecting block 11. A second fixing hole 13 is opened in the middle of the two first fixing plates 12. A snap-fit ​​block 8 is fixedly connected to one side of the connecting block 11. A snap-fit ​​groove 10 is opened between the connecting block 11 and the snap-fit ​​block 8. A rivet 7 is bolted to the inner cavity of the first fixing plate 12. The first fixing plate 12 is connected to the connecting rod 6 through the rivet 7. The first car wall 3 is connected to the snap-fit ​​groove 14 on the second car wall 4 through the snap-fit ​​block 8. The second car wall 4 is connected to the second car wall 4 on the third car wall 5 through the snap-fit ​​block 8. The connecting block 11, the first fixing plate 12 and the snap-fit ​​block 8 are all made of stainless steel.

[0018] In this embodiment of the application, the second fixing holes 13 on the first fixing plates 12 at both ends of the connecting block 11 are aligned with the connecting rods 6 on the first car wall 3, the second car wall 4 and the third car wall 5 and evenly arranged. Then, they are fixed by rivets 7. During installation, the snap-fit ​​block 8 is inserted into the snap-fit ​​groove 14. After passing through, it is snapped and limited by the snap-fit ​​groove 10 to prevent the car wall from shifting.

[0019] The connection structure is made of stainless steel. Stainless steel has excellent processing performance and can be made into complex shapes such as buckles and bolt holes through processes such as stamping and welding to meet the needs of rapid installation. At the same time, it has high strength and good toughness, and can withstand the load and vibration of the elevator car to ensure stable connection. The surface is smooth and easy to clean, combining aesthetics and practicality. A dense oxide film is formed on the surface, which is resistant to moisture and acid and alkali corrosion, making it suitable for the complex environment of elevator shafts and extending the structural life.

[0020] In practical use: Four connecting structures are evenly arranged and installed on the connecting rods 6 of the first car wall 3, the second car wall 4, and the third car wall 5 through the second fixing holes 13 opened on the first fixing plates 12 at both ends of the connecting block 11. Then, they are fixed with rivets 7. Then, the first car wall 3 is installed on the car bottom 1 by external equipment and fixed with bolts. Then, the second car wall 4 is lifted by external equipment. During installation, the snap-fit ​​block 8 on the connecting block 11 is inserted into the snap-fit ​​groove 14.
