AI Technical Summary
The existing positioning flap structure is cumbersome to operate in rail transit and lacks safety. It is necessary to simplify the operation process and improve safety.
It adopts a combination structure of fixed plate, flip plate, insertion plate, insertion plate seat and rotating shaft. The insertion and removal of the insertion plate is realized by the rotating shaft moving horizontally in the waist groove of the flip plate, which simplifies the operation steps and eliminates the complex positioning structure.
It enables single-step operation positioning or flattening transition of the flip-up plate, improving safety and ease of operation, reducing costs and facilitating maintenance.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit, and in particular to a positioning flip-plate structure that is easy to operate. Background Technology
[0002] In the field of rail transit, lifting platform equipment is usually equipped with a flap device in the gap area of the platform to fill the gap and provide a connecting transition. The existing positioning flap consists of a hinge and a manual positioning operation device, which is complex, cumbersome to operate, and lacks safety. It requires step-by-step operation to achieve the working posture.
[0003] Therefore, it is necessary to develop a new type of positioning flip-plate structure to overcome the above problems. Utility Model Content
[0004] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides a positioning flip-plate structure that is easy to operate, has a stable structure, is convenient to operate and has strong adaptability, is safe and reliable, and improves safety and user experience.
[0005] Technical solution: The present invention provides a simple-to-operate positioning flip-plate structure, characterized in that it includes a fixed plate, a flip-plate, an insert plate, an insert plate seat, and a rotating shaft; the fixed plate and the flip-plate are connected by the rotating shaft; the insert plate is inserted into the slot of the insert plate seat.
[0006] The flap is provided with handle holes.
[0007] The handle hole is a rounded rectangular structure.
[0008] The flap is provided with a waist groove.
[0009] The rotating shaft can move horizontally within the groove of the flap.
[0010] Beneficial effects: Compared with the prior art, this utility model has the following significant advantages: This utility model optimizes the hinge structure and positioning mechanism, enabling the positioning or flattening transition of the flip panel to be achieved in one operation. It eliminates the complex positioning structure and uses rigid parts that are simple in design, low in cost, and easy to maintain. This makes the flip panel safer, more reliable, and easier to operate during use. Attached Figure Description

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] like Figure 1 , 2 As shown in Figure 3, the positioning flip plate device is connected to the fixed plate 1 and the flip plate 2 through the rotating shaft 5. The flip plate 2 is lifted through the handle hole, and the insert plate 3 is vertically inserted into the slot of the insert plate seat 4, so that the device is in a vertical state. The reason for this function is that the device has the following structure: the rotating shaft 5 can move horizontally in the waist groove of the flip plate 2, so that the insert plate 3 can have enough space to flip and insert into the slot of the insert plate seat 4.
[0019] Example 1:
[0020] like Figure 4 The flap can be installed at the end of the maintenance trolley platform to serve as a ramp for easy loading and unloading. After use, the flap can be turned vertically as a baffle to prevent goods from falling.
[0021] Example 2:
[0022] like Figure 5 The flap can be installed at the train door sill and used as a platform gap transition board to facilitate passengers getting on and off the train. After use, the flap can be turned vertically and used as a barrier to prevent people and goods from falling out if the train door is accidentally opened.
[0023] This invention optimizes the hinge structure and positioning mechanism, enabling the flap to be positioned or flattened in a single operation. It eliminates the complex positioning structure and uses simple, low-cost, and easy-to-maintain rigid parts. This makes the flap safer, more reliable, and easier to operate during use.
