If the specific posture changes, the directional indications will also change accordingly.

[0020] In the present utility model, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] In addition, in the present utility model, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. Additionally, the technical solutions between various embodiments may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0022] The following will further describe the present utility model in detail with reference to the Figures 1-3 accompanying drawings.

[0023] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: an anti-misoperation device for the emergency stop button of an escalator, including an emergency stop installation base 1 and an emergency stop button 2; the emergency stop installation base 1 is installed at the entrance and exit of the escalator or moving walkway through a fixing member 5; wherein: an accommodation cavity 11 is opened at the upper end of the emergency stop installation base 1; the emergency stop button 2 is installed in the accommodation cavity 11; an anti-misoperation cover 4 that can be turned outwards is arranged on the accommodation cavity 11 through a rotation reset assembly 3; the anti-misoperation cover 4 covers the emergency stop button 2 under normal conditions; an arc-shaped operation part 41 is arranged at one end of the anti-misoperation cover 4 that is turned outwards. By setting the anti-misoperation cover 4, the present utility model isolates the emergency stop button 2 from the outside world, avoiding the accidental operation of the emergency stop button 2 by passengers or luggage, resulting in the emergency stop of the escalator or moving walkway, ensuring the normal operation of the escalator or moving walkway, and providing a good passenger experience. When an emergency occurs, by setting the arc-shaped operation part 41, it is convenient to manually lift the anti-misoperation cover 4 and press the emergency button to immediately stop the running escalator (moving walkway) until the emergency is eliminated before it can be restarted, ensuring the safety and reliability of the passenger's riding process.

[0024] Specifically, in the solution of this embodiment, the rotation and reset assembly 3 includes a pin shaft 31, a left torsion spring 32 and a right torsion spring 33; a through hole for installing the pin shaft 31 is provided on the emergency stop mounting base 1; rotating sleeves are symmetrically arranged on the upper part of the anti-misoperation cover 4; the pin shaft 31 passes through the right torsion spring 33, the rotating sleeve and the left torsion spring 32 in sequence and is installed on the emergency stop mounting base 1; one end of the right torsion spring 33 is fixed on the emergency stop mounting base 1, and the other end is fixed on the anti-misoperation cover 4; one end of the left torsion spring 32 is fixed on the emergency stop mounting base 1, and the other end is fixed on the anti-misoperation cover 4; the anti-misoperation cover 4 is turned outwards and opened around the pin shaft 31. It should be noted that when an emergency occurs and the emergency button needs to be pressed, a passenger or a staff member puts a finger into the accommodation cavity 11 from the arc-shaped operation part 41, and then turns the anti-misoperation cover 4 outwards. At this time, the left torsion spring 32 and the right torsion spring 33 are in a twisted (compressed) state, thereby generating torque or rotational force. After the emergency stop button 2 is pressed, the anti-misoperation cover 4 returns to its initial position under the action of the torque or rotational force, that is, the anti-misoperation cover 4 covers the emergency button again, playing an insulating role to prevent the emergency stop button 2 from being accidentally actuated by a passenger or luggage, resulting in the emergency stop of the escalator or moving walkway, ensuring the normal operation of the escalator or moving walkway and providing a good passenger experience. It should be noted that the torsion spring belongs to a helical spring. The end of the torsion spring is fixed to other components. When other components rotate around the center of the spring, the spring pulls them back to the initial position, generating torque or rotational force. The torsion spring can store and release angular energy or statically fix a device by rotating a force arm around the central axis of the spring body.

[0025] Specifically, in the solution of this embodiment, the rotation and reset assembly 3 further includes a plug pin 34; a limiting end 311 is provided at one end of the pin shaft 31; the other end of the pin shaft 31 is installed on the emergency stop mounting base 1 through the plug pin 34. It should be noted that the provision of the limiting end 311 at one end of the pin shaft 31 enables one end of the pin shaft 31 to be quickly positioned and installed on the emergency stop mounting base 1. The other end of the pin shaft 31 is quickly fixed on the emergency stop mounting base 1 through the plug pin 34. By the fixing method of the plug pin 34, it is detachable, which is convenient for later maintenance work.

[0026] Specifically, in the solution of this embodiment, a wiring terminal 12 is provided at the bottom of the emergency stop mounting base 1; the wiring terminal 12 is used for electrically connecting the emergency stop button 2 and the control system of the escalator.

[0027] Specifically, in the solution of this embodiment, the anti-misoperation cover 4 is made of a transparent material, and the transparent anti-misoperation cover 4 is convenient for passengers or staff members to more intuitively find the emergency button.

[0028] Specifically, in the solution of this embodiment, the fixing member 5 is a fixing bolt.

[0029] Specifically, in the solution of this embodiment, an emergency button prompt word is provided on the top surface of the anti-misoperation cover 4 to facilitate the staff or passengers to quickly find the emergency button.

[0030] The technical solutions provided by the embodiments of the present invention have been introduced in detail above. Specific examples are used in this article to elaborate on the principles and implementation manners of the embodiments of the present invention. The descriptions of the above embodiments are only applicable to helping understand the principles of the embodiments of the present invention; at the same time, for those of ordinary skill in the art, based on the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
