Description

Technical Field

[0001] This utility model relates to the field of industrial elevators, specifically to a folding door for a car. Background Technology

[0002] Industrial elevators are widely used in construction, bridge towers, chimneys, etc., providing convenience for personnel maintenance and goods transportation. However, the spaces available in these applications are relatively limited. Conventional elevators often use a top-and-bottom door design, which has the following disadvantages: 1. Top-and-bottom doors occupy space at the bottom or top of the car; 2. Top-and-bottom doors require an additional counterweight system, commonly using wire ropes or chains, which are frequently used, prone to damage, and difficult to replace; 3. Externally mounted doors increase the external dimensions of the car, further compressing the internal space when installed in limited areas. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the above-mentioned background technology and provide a car folding door that makes the overall structure of the car more compact and beautiful, while effectively saving the bottom installation space.

[0004] The purpose of this utility model is achieved through the following technical measures: a car folding door, including a mounting plate, a sealing strip, a door panel one, a door panel two, a sliding groove, a slider, a mounting base, a fixing plate, left and right frames, and a door handle. The mounting base and the mounting plate are fixed by bolts, and the fixing plate and the mounting plate are fixedly connected by bolts. After the two are fixed together, the bottom is open, forming an upper sliding groove. The mounting plate, the left and right frames, and the sliding groove form a folding door mounting frame. The door panel one and the door panel two are connected by hinges. The upper and lower parts of the door panel two are respectively fixed with sliders. The door panel one and the mounting base are connected by a sleeve and a pin.

[0005] In the above technical solution, sealing strips are affixed to the sides and top of door panel one and door panel two.

[0006] In the above technical solution, door panel one and door panel two adopt a symmetrical design, which supports the interchange of the installation positions of the left and right doors.

[0007] In the above technical solution, the door panel adopts a concave design to provide space for the door handle when the door is opened and folded.

[0008] Compared with the prior art, the folding door of this utility model has the following significant advantages:

[0009] 1. Easy to install and disassemble: The connection method of sleeve and pin greatly simplifies the installation and disassembly process of door panel and improves maintenance efficiency.

[0010] 2. Excellent sealing performance: The side and top sealing strips effectively prevent dust from entering the car and significantly reduce operating noise. In particular, the top sealing strip has a significant effect on suppressing the impact noise of the door opening, thus improving the ride comfort.

[0011] 3. Low-resistance operation: The double sliding structure design optimizes the force distribution and significantly reduces the frictional resistance during the opening and closing process, making the door operate more easily and smoothly.

[0012] 4. High versatility and interchangeability: The universally designed door panels can be interchanged between left and right sides, reducing the types of spare parts and inventory costs, and improving the flexibility of installation and maintenance.

[0013] 5. Increased effective space: The concave design of the door panel provides folding space for the door handle, which can increase the actual effective opening size of the car under the same conditions and improve the passage.

[0014] 6. Reliable and durable structure: The overall structure is reasonably designed, and the stability and durability of the door are ensured by the mounting base and sliding mechanism. Attached Figure Description
