Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rail transit platform safety door, in particular to a flexible stopper applied to platform door. BACKGROUND

[0002] The platform safety door is arranged along the platform edge, and when the vehicle enters the platform, the door is aligned with the sliding door or emergency door / end door position of the safety door after parking to allow passengers to get on and off the vehicle or to escape in emergency. The emergency door serves as an escape door and plays a crucial role in the entire platform safety door system; the end door provides a channel for station staff to enter and exit the track side and for passengers to quickly enter the platform in emergency. For the emergency door / end door, the staff or passengers can push the push rod from the track side to open the door, and the platform personnel can open it from the platform side with a key.

[0003] The platform emergency door / end door usually does not have a damper to quickly open in emergency. However, sudden opening of the emergency door / end door with great force can cause collision of the emergency door / end door, and in some platform layouts, opening angle that is too large can affect the function of adjacent door bodies. Therefore, the emergency door / end door usually needs to have certain limiting function. The existing emergency door / end door mechanical limiting has complex structure, high cost, small adjustable space, and high difficulty in modification. UTILITY MODEL CONTENT

[0004] The utility model aims at overcoming the defects of the prior art and provides a flexible stopper applied to platform door, which can realize opening limiting of the emergency door or end door.

[0005] One technical solution to achieve the above-mentioned purpose is: a flexible stopper applied to platform door to realize opening limiting of the emergency door or end door, comprising a first column, a second column and a door body.

[0006] One side of the door body is the hinge side, and the door body on this side is connected with the first column through a hinge and a door shaft. A fixed seat is arranged on the column body on the side of the first column facing the second column, and a fixed seat is also arranged on the corresponding position of the door body hinge side facing the first column. A clamping groove is formed on one side of the connecting surface of the fixed seat, the flexible stopper passes through the clamping grooves of the fixed seats on the first column and the door body respectively, and the two ends of the flexible stopper are fixed on the fixed seats.

[0007] In the closed door state, the flexible stopper is in a natural flexible state.

[0008] When the door body is opened to a preset angle, the flexible stopper is taut, limiting the opening angle of the door body.

[0009] Further, the flexible stopper is a steel wire rope.

[0010] Furthermore, the flexible limiter is a belt.

[0011] Furthermore, the belt has a pre-fold line in the middle to guide the folding direction.

[0012] Furthermore, several sets of fixing seats are provided on the first column and the door body along the vertical direction.

[0013] This utility model has the following advantages: The flexible limiter of this utility model applied to platform doors effectively solves the problem of limiting the opening of emergency doors / end doors. The flexible limiter has high flexibility, adjustable limit angle, high adjustability, simple installation, convenient maintenance, and overall reliability and safety. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of a flexible limiter applied to a platform door according to the present invention;

[0015] Figure 2 A schematic diagram of the closed state of the platform door for applying this utility model;

[0016] Figure 3 This is a schematic diagram of the platform door opening state in accordance with the present invention. Detailed Implementation

[0017] To better understand the technical solution of this utility model, a detailed description is provided below through specific embodiments:

[0018] Please see Figures 1 to 3 This utility model discloses a flexible limiter for use in platform doors, which is used to limit the opening of emergency doors or end doors.

[0019] This utility model specifically includes a first column 6, a second column, and a door body 1.

[0020] The side of the door 1 closest to the first pillar 6 is the hinge side. This side of the door is connected to the first pillar 6 via hinges 3 and a door pivot 2, enabling the door 1 to open and close. A fixing seat 5 is provided on the side of the first pillar 6 facing the second pillar, and a corresponding position is also provided on the hinge side of the door 1 facing the first pillar.

[0021] A fixed base 5 is provided. A snap-fit ​​groove is opened on the side of the fixed base 5 where it connects with the first column 6 or the door body 1. The flexible limiter 4 passes through the snap-fit ​​groove of the fixed base on the first column and the door body respectively, and both ends of the flexible limiter are fixed to the fixed base. The fixed base 1 is a casting or a machined part.

[0022] When the door is closed, the flexible limiter is in a natural, flexible state. When the door is opened, the door 1 will open under the action of the door hinge 2 and the hinge 3. The flexible limiter 4 will be tensioned during the opening process until it is fully tightened. At this time, the door opens to the preset angle, thereby achieving the purpose of limiting the door.

[0023] Please see Figure 2 When the door is closed, the door body 1 is fixed to the two pillars. A push-rod lock 11 is installed on the door body 1.

[0024] Please see Figure 3 When the door is open, the hinge end of the door 1 is fixed to the first column 6.

[0025] In one embodiment, the flexible limiter is made of steel wire rope. Steel wire rope is easy to insert and install, has a small size, and has high strength.

[0026] In another embodiment, the flexible limiter is a belt with a pre-fold line in the middle to facilitate folding in a preset direction when the door is closed.

[0027] In the above embodiments, the specific installation position of the fixed base 5 can be adjusted, and the position and reserved length of the flexible limiter 4 in the fixed base can also be adjusted, thereby allowing the limiting angle to be adjusted as needed. After adjustment, the position of the flexible limiter 4 in the fixed base is then fixed.

[0028] like Figure 1 As shown, this embodiment uses a set of fixed seats. In actual implementation, several sets of fixed seats can be set along the vertical direction of the first column and the door as needed, and several sets of flexible limiters can be used.

[0029] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
