DETAILED DESCRIPTION
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] like Figures 1-5 The diagram shows a deformation suppressor for a railway station anti-theft roller shutter door, including a base plate 1. Two L-shaped limiting structures 2 are symmetrically arranged in the middle of the base plate 1. A gap is reserved between the two L-shaped limiting structures 2 for the anti-theft roller shutter door to pass through. Support components 3 for stabilizing the L-shaped limiting structures 2 are provided on the side of the two L-shaped limiting structures 2 that are far apart from each other.
[0024] The L-shaped limiting structure 2 includes a fixed plate 201, a vertical first limiting plate 202, and a top outwardly inclined second limiting plate 203. The fixed plate 201 is connected to the base plate 1 by bolts. The upper part of the first limiting plate 202 has a connecting hole 204 for fixing to the support assembly 3. The distance between the second limiting plates 203 of the two L-shaped limiting structures 2 gradually decreases from top to bottom. During the descent of the curtain slats, to prevent swaying, misalignment, and squeezing or collision with the structure, an opening with a gradually decreasing gap is provided to ensure that the curtain slats do not squeeze or collide with the structure.
[0025] The support assembly 3 comprises a first connecting plate 301, an inclined support plate 302 and a second connecting plate 303, the first connecting plate 301 is connected with the bottom plate 1 through bolts, and the second connecting plate 303 is connected with the L-shaped limiting structure 2 through bolts.
[0026] Four mounting holes 101 are arranged on the bottom plate 1, the mounting holes 101 are arranged on both sides of the middle position of the straight line where the curtain piece of the anti-theft roller shutter door is vertically projected on the ground, and the bottom plate 1 is fixed to the ground through the countersunk bolts. In the daily non-use state, the countersunk bolts are closed, and the normal access of passengers is not affected.
[0027] In extreme windy weather, the anti-theft roller shutter door of the station entrance is in a fully closed state, and the force area is large, and the curtain piece will be deformed and separated from the guide rail due to the change of wind direction. The bottom plate of the station anti-theft roller shutter door deformation suppressor is fixed to the predetermined point position of the straight line where the curtain piece of the anti-theft roller shutter door is vertically projected on the ground through the countersunk bolts, and a fixed component is formed. After the station anti-theft roller shutter door is closed and lowered, it falls into the middle of the two L-shaped limiting structures. When the curtain piece of the anti-theft roller shutter door is deformed by the wind in two directions, it will contact one of the two L-shaped limiting structures. At this time, the L-shaped limiting structure will provide a counter supporting force for the curtain piece of the anti-theft roller shutter door, thereby preventing the curtain piece of the anti-theft roller shutter door from deforming and separating from the guide rail. Through the support assembly, a triangle is formed with the L-shaped limiting structure and the bottom plate, and a reinforcing support is provided by using the triangle stability principle.
[0028] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
