Problems solved by technology

On the one hand, this kind of door lock structure has great potential safety hazards, because when the vehicle is driving, the road surface is bumpy and hollow, and the guide wheel on the door lock will roll back and forth in the guide groove, which will cause the door to be closed. Poor, when running at high speed, the airflow will enter the car from the door gap, affecting the passenger experience; when the vibration is large, the guide wheel may even slide out from the original path in the guide groove, which will cause the door to be broken. Automatic opening, there is a great security risk
On the other hand, in this door lock structure, the power source is fixed on the door frame, and the driving end of the power source is fixed on the guide wheel. When the door is closed or opened, the power applied by the power source is all applied to the guide wheel, and the guide wheel The wheel is the only point of force, and it is easy to cause the guide wheel to be damaged and accelerated due to stress concentration, and because there is only this point of force, when closing or opening the door, the door panels on both sides cannot be guaranteed to be absolutely synchronized, which will cause the two sides to close Or the absolute balance cannot be guaranteed when opening, which may easily cause the door panel to shake
[0004] In order to solve the above-mentioned potential safety hazards, the general solution is to add a cylinder or motor to pull the guide wheel after the door is closed, so that the guide wheel is limited in the guide groove, but this method needs to be used after the door is closed. The larger pulling force limits the position of the guide wheel; and the above-mentioned problem of instability when closing or opening the door has not been solved well, which does not conform to the concept of green environmental protection in today's society
The second is that the escape window has a certain height, and passengers will fall if they climb over the window, causing secondary injuries

Embodiment approach 1

[0070] This embodiment provides a double Sierra escape door, such as Figures 1 to 11 , 19 to 25, mainly by the base 1 fixed on the door frame 20, two groups of shaft-connected drive mechanisms 2, slide rod 3, pull rod 4, two sliding sleeves 5, wire drawing 6, two wire drawing wheels 7, Guide wheel 8, gas spring 21, two door frames 10, two door panels 11, four safety locks 25 and a manual unlocking pull bar 24 form.

[0071] Two sets of shaft-connecting drive mechanisms 2 are respectively installed on both ends of the upper part of the base 1. The two sets of shaft-connecting drive mechanisms 2 are mainly composed of a sliding bracket 201, a driving arm 202 and a connecting arm 203. The sliding brackets in the two sets of coupling driving mechanisms 2 201 is fixedly connected through the slide bar 3, and the driving arm 202 is rotatably connected through the pull rod 4, and the slide bar 3 and the pull rod 4 are parallel to each other. Among the two groups of shaft-connecting...

Embodiment approach 2

[0078] This embodiment is a further improvement of Embodiment 1. The main improvement is that in Embodiment 1, when the emergency situation is over and it is necessary to close the opened double-serra safety door, it is necessary to manually turn the escape doors on both sides to After pushing hard in the middle to close, re-lock the four safety locks 25 on both sides; since the escape door is in the emergency opening state of the gas spring 21, the gas spring 21 is always in an extended state. Pushing the escape door to the middle to close the escape door is very time-consuming and laborious, and the operation is difficult. However, in this embodiment, the above-mentioned defects can be effectively overcome.

[0079] Specifically, the double plug safety door in this embodiment also includes a driving cylinder, which is fixed on the pull rod, and its telescoping end is fixedly connected with the sliding sleeve 5 connected with the guide wheel 8 . After the Sierra escape door ...

Embodiment approach 3

[0086] This embodiment is a further improvement of Embodiment 2. The main improvement is that in Embodiment 2, when the emergency is over, it is necessary to manually pull the manual unlocking lever first, and pull the unlocking piece of the safety lock 25 through the unlocking wire 23 to release it. After the safety lock 25 is unlocked, the gas spring 21 can be stretched quickly to open the door panel. The pulling of the manual unlocking lever requires manpower. In this embodiment, a pneumatic unlocking cylinder 22 is installed on the inner wall of the double-serra escape door, and the telescopic end of the pneumatic unlocking cylinder 22 is connected to the unlocking pieces of each safety lock 25 through unlocking wires 23 .

[0087] The setting of the pneumatic unlocking cylinder 22 enables the opening of the safety lock 25 to be opened pneumatically. The operation is only to touch the opening button of the pneumatic unlocking cylinder 22. After the pneumatic unlocking cylin...

Abstract

The invention relates to the field of sliding-plug doors, and discloses a sliding-plug escape door. The sliding-plug escape door comprises a base fixed to the upper part of a door frame; the two endsof the base are each provided with one group of connecting shaft driving mechanism; the two groups of connecting shaft driving mechanisms are fixedly connected through a sliding rod and rotationally connected through a pull rod; at least one and at most two sliding sleeves are arranged on the sliding rod in a sleeving mode; a guide wheel rotationally connected to one sliding sleeve is limited in aguide groove in the base; and each sliding sleeve is fixedly connected with a door plate through a door carrying frame; a gas spring is fixed on the pull rod; and the telescopic end of the gas springis fixedly connected with the sliding sleeve connected with the guide wheel; the connecting shaft driving mechanisms can do reciprocating motions relative to the base under the driving of the gas spring and external force respectively so as to drive the door plate to be opened and closed; at least one manually-unlocked safety lock is further mounted on each of the two sides of the door plate; andan unlocking piece of each safety lock is connected with a corresponding manual unlocking pull rod through an unlocking pull wire. The sliding-plug escape door is opened towards the two sides by being attached to a vehicle body in emergency, does not occupy much space outside the vehicle, is not prone to colliding with obstacles outside the vehicle and is easy to open.

Description

technical field [0001] The invention relates to the field of driving mechanisms, in particular to a Sierra escape door. Background technique [0002] At present, bus doors, subway doors or high-speed rail doors usually use sliding doors. The sliding door has good sealing performance and takes up less space, making the overall model beautiful and generous. The quality of the sliding door lock directly affects the quality of the sliding door. Security and sealing, in order to improve the security of sliding door, the researcher in the field mainly puts the object of research on the structure of sliding door lock. [0003] The currently used plug door lock structure is usually when the door is closed, a guide wheel on the door lock is introduced into the guide groove through a guide groove on the vehicle frame, and the movement of the door lock is restricted by this guide groove, and the door The lock is fixed on the car door, so that the movement of the car door is restricted...
