Description

Technical Field

[0001] The utility model relates to the field of elevator cars, in particular to an insert-type car wall structure. Background Art

[0002] The elevator car is a part of the elevator, also known as the elevator car or elevator cabin. The elevator car is the core component of the elevator operation. It is an enclosed space used to transport passengers or goods between different floors in a building.

[0003] The elevator car consists of a car shell and a car door. The car shell is the outer surrounding structure of the elevator car, usually made of steel plates or other strong materials. It has sufficient strength and rigidity to withstand the pressure and load during operation and provide a safe space for passengers and items. The elevator car is equipped with doors inside and outside for passengers to enter and exit the car.

[0004] Currently Figure 1 As shown, the car shell includes a car roof 01 arranged at the top, car walls 02 arranged around, and a car bottom 04 arranged at the bottom, and the three are fixed to form a cubic box body by a common welding method. A skirting board 03 is also welded between the bottom of the car wall 02 and the car bottom 04. The upper and lower ends of the skirting board 03 are bent to increase the welding contact area, and the skirting board 03 also supports the car wall 02.

[0005] But I encountered the following problems when using it:

[0006] The car top 01 and the car wall 02 are fixed at the top, and the car wall 02 and the skirting board 03 are fixed at the bottom. The above-mentioned upper and lower fixing methods result in a small contact area at the connection position of the components, a large load per unit area of ​​the contact surface, and a loose welding point, which affects the stability of the elevator car. In addition, due to the small area of ​​the welding point, it is difficult for the workers to weld. The use of the skirting board 03 will increase the deadweight of the car shell, complicate the structure of the elevator car, and increase the additional load on the lifting motor, which also affects the stability of the elevator car. Summary of the invention

[0007] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a plug-in type car wall structure, which has the advantage of simplifying the basis of the elevator and ensuring structural stability.

[0008] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] A plug-in car wall structure comprises a car top plate, a car side plate and a bottom plate:

[0010] The top of the car side panel is provided with a plug-in groove 1, the edge of the car top panel is inserted into the plug-in groove 1, and the side of the car top panel is fitted with the car side panel;

[0011] The top edge of the car side plate is provided with a plurality of positioning grooves 1, and the positioning grooves 1 are threadedly connected with hexagonal bolts, and the hexagonal bolts fix the side of the car top plate and the car side plate;

[0012] The bottom of the car side panel is provided with a second plug-in slot, the edge of the bottom panel is inserted into the second plug-in slot, and the side of the bottom panel is fitted with the car side panel;

[0013] The bottom edge of the car side plate is provided with a plurality of positioning grooves 2, the positioning grooves 1 and the positioning grooves 2 correspond to each other one by one, and the positioning grooves 2 are threadedly connected with hexagonal bolts to fix the side of the bottom plate and the car side plate.

[0014] Furthermore, the positioning groove 1 is arranged along the width direction of the car side panel, and the slotting direction of the positioning groove 1 is the height direction of the car side panel.

[0015] Furthermore, the second positioning groove is arranged along the width direction of the car side plate, and the slotting direction of the second positioning groove is the height direction of the car side plate.

[0016] Furthermore, the hexagonal bolt is threadedly connected with a hexagonal nut.

[0017] Furthermore, a flat washer is sleeved on the hexagonal bolt, and the flat washer is located between the hexagonal nut and the car side plate.

[0018] Furthermore, a spring washer is sleeved on the hexagonal bolt, and the spring washer is located between the flat washer and the hexagonal nut.

The four sides and bottom of the car top plate are supported, and the contact area between the car top plate and the car side plate is increased to improve stability; similarly, the bottom of the bottom plate and the car side plate are also inserted into each other, which is conducive to increasing the installation stability of the bottom plate.

[0024] 2. The car top and bottom plates are locked with the car side plates by the combination of hexagonal bolts and hexagonal nuts, and the connection structure is simple.

[0025] 3. Flat washers increase the contact area with the car side panels, reduce the pressure per unit area, and reduce the situation where the hexagonal nuts over-tighten the car side panels.

[0026] 4. The spring washer itself has good elasticity. When the spring washer is pressed by the hexagonal nut, the spring washer has a tendency to rebound, which prevents the hexagonal nut from loosening. BRIEF DESCRIPTION OF THE DRAWINGS
