Description

Technical Field

[0001] This utility model relates to the field of safety facility technology, and in particular to a railway platform lifting protection device with built-in identification and unlocking function. Background Technology

[0002] Railway platform lifting safety devices play a safety protection role on railway platforms, preventing passengers from entering dangerous areas while waiting for their trains.

[0003] Currently, some electronic components of railway platform lifting safety devices are directly installed on the opening and closing doors. This allows for maintenance work simply by opening the doors (when maintaining components such as displays and speakers). However, there is a drawback: the NFC tag sensor used for NFC-based unlocking is fixed to the opening and closing doors with bolts. This method is cumbersome and depends on the condition of the bolts. For example, the bolts may become difficult to unscrew due to corrosion, which greatly complicates the disassembly process. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the prior art by providing a railway platform lifting protection device with built-in identification and unlocking function to solve the aforementioned problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This railway platform lifting protection device with built-in identification function unlocking device includes a box, a lifting frame movably installed in the box, and a rope connected to the lifting frame. A box door is hinged on the box for setting up components such as a display screen and locked to the box by an electric lock. The box door has a positioning slot for limiting the NFC tag sensor electrically connected to the electric lock to the final assembly position of the box door. The positioning slot has an extension groove on the box door that extends to one side and serves as a dwell space for the NFC tag sensor before entering or after exiting the positioning slot. A swingable cover plate is provided in the extension groove to hide the extension groove. A locking component is provided between the cover plate and the extension groove to keep the cover plate closed, and the NFC tag sensor is also limited to the positioning slot when the cover plate is closed.

[0006] Further improvements include interconnection between the positioning slot and the extension slot. The positioning slot has symmetrically distributed protrusions at its opening end, forming a clamping space. The protrusions contain a guide channel that guides the NFC tag sensor into the clamping space. After the NFC tag sensor enters the guide channel, the movement of the NFC tag sensor is limited in four directions: up, down, forward, and backward.

[0007] Further improvements were made, such that when the cover is closed, it interferes with the path of the NFC tag sensor exiting the guide channel.

[0008] Further improvements include a moving block with a locking rod, a rod support, a spring connecting seat, and a spring. The rod support and spring connecting seat are both located on the inner end face of the cover plate. The moving block is located between the rod support and the spring connecting seat. The locking rod at one end passes through the rod support and has a first spring connecting post at the other end. One end of the spring connecting seat has a second spring connecting post opposite to the first spring connecting post. One end of the spring is inserted into the first spring connecting post and the other end is inserted into the second spring connecting post. The spring is compressed and deformed when the locking rod moves in the unlocking direction. A limiting seat with a lock hole is provided on the inner end face of the door for the locking rod to be inserted into.

[0009] Further improvements include an inclined surface at the end of the locking bar that enters the locking hole of the limiting seat.

[0010] Further improvements include a socket located above the moving block on the cover plate, with a rotatable unlocking lever inside the socket, and a cavity inside the unlocking lever for inserting auxiliary tools.

[0011] The beneficial effects of this utility model are:

[0012] This invention enables convenient and rapid assembly of NFC tag sensors and cabinet doors, and allows for maintenance either by opening the cabinet door or by maintaining the cabinet door without opening it. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Referring to the attached diagram: This railway platform lifting protection device with built-in identification unlocking device includes a housing 1, a lifting frame 2 movably installed inside the housing 1, and a rope 3 connected to the lifting frame 2. A door 4 is hinged to the housing 1 for mounting components such as a display screen and is locked to the housing 1 by an electronic lock. The door 4 has a positioning slot 41 for limiting the final assembly position of an NFC tag sensor 5 electrically connected to the electronic lock. The positioning slot 41 has an extension groove 42 on the door 4 that extends to one side and serves as a dwell space for the NFC tag sensor 5 before entering or after exiting the positioning slot 41. A swingable cover plate 6 is provided in the extension groove 42 to hide the extension groove 42. A locking component 7 is provided between the cover plate 6 and the extension groove 42 to keep the cover plate 6 closed, and also to limit the NFC tag sensor 5 within the positioning slot 41 when the cover plate 6 is closed. The principle of this utility model is that the door 4 is used to install some components, namely the display screen, scanning radar, wireless sensor, and speaker. The door 4 and the cabinet 1 are locked together by an electric lock (the electric lock is a commonly used and technologically mature component on the market, and is equipped with a manual key to unlock it, to prevent the NFC tag sensor 5 from being damaged and unable to unlock; therefore, the specific usage structure and principle will not be described in detail). The NFC tag sensor 5 is used to control the unlocking of the electric lock. That is, when the staff touches the lock with an electronic card or an electronic product with NFC information, the lock is triggered, and the electric lock is unlocked. This allows the door 4 to be opened to inspect or maintain the components inside the cabinet 1. Moreover, considering that the NFC tag sensor 5 is a consumable part, it will be damaged due to environmental factors, depreciation, etc. In order to achieve quick replacement of the NFC tag sensor 5 without opening the door 4, the positioning slot 41 and extension slot 42 are set on the door 4. The positioning slot 41 is used to limit the final assembly of the NFC tag sensor 5 on the door 4. The positioning slot 41 has constraints that only allow the NFC tag sensor 5 to move along the assembly direction, while the extension slot 42 does not have these constraints. Therefore, the NFC tag sensor 5 is placed in the extension slot 42 during assembly or disassembly (i.e., by first inserting it into the extension slot 42 and then into the positioning slot 41, or by exiting it from the positioning slot 41 and then entering the extension slot 42). When it enters the extension slot 42 first, wiring is performed in the extension slot 42; when it enters the extension slot 42 later, wiring is disconnected in the extension slot 42. A cover plate 6 is provided inside the extension slot 42, and the cover plate 6 is connected to... The extension slot 42 is pivotally connected to allow for swinging. When it is closed, the extension slot 42 can be hidden, and the wireless sensor 5 can also be confined within the positioning slot 41 (and released from the positioning slot 41). Hiding the extension slot 42 is to prevent dust and other impurities from entering the housing 1. It also serves as a confinement mechanism, eliminating the need for additional fixing structures within the positioning slot 41. This allows for convenient and quick assembly when removing and installing the NFC tag sensor 5, and assembly can be performed with or without opening the housing door 4.

[0022] The positioning slot 41 and the extension slot 42 are interconnected. The positioning slot 41 has protrusions 8 symmetrically distributed at its opening end to form a clamping space 411. The protrusions 8 have a guide channel 81 that guides the NFC tag sensor 5 into the clamping space 411. After the NFC tag sensor 5 enters the guide channel 81, the protrusions 8 limit the movement of the NFC tag sensor 5 in four directions: up, down, front, and back. The protrusions 8 form the guide channel 81. The guide channel 81 is a connecting structure, that is, the NFC tag sensor 5 has a part that is inserted into the guide channel 81. The clamping space 411 formed between the two protrusions 8 allows the main body of the NFC tag sensor 5 to be placed inside, so that its upper and lower end faces can fit with the upper and lower end faces of the protrusions 8 at different positions, thereby increasing the assembly stability. The guide channel 81 provides the NFC tag sensor 5 with an entry end only at the inlet end on one side, which also limits the assembly direction of the NFC tag sensor 5 and the guide channel 81.

[0023] When the cover plate 6 is in the closed state, it interferes with the path of the NFC tag sensor 5 exiting the guide channel 81. That is, it closes the entrance end of the guide channel 81 that allows the NFC tag sensor 5 to enter. In other words, the cover plate 6 is used as a sealing component to prevent the NFC tag sensor 5 from exiting after entering the guide channel 81.

[0024] The locking assembly 7 includes a movable block 71 with a locking rod 711, a rod support 72, a spring connecting seat 73, and a spring 74. The rod support 72 and the spring connecting seat 73 are both located on the inner end face of the cover plate 6. The movable block 71 is located between the rod support 72 and the spring connecting seat 73. The locking rod 711, located at one end, passes through the rod support 72, and its other end is provided with a first spring connecting post 712. One end of the spring connecting seat 73 is provided with a second spring connecting post 731, which is opposite to the first spring connecting post 712. One end of the spring 74 is inserted into the first spring connecting post 712, and the other end is inserted into the second spring connecting post 731. The spring 74 is compressed and deformed when the locking rod 711 moves in the unlocking direction. The inner end face of the door 4 has a lock hole for inserting the locking rod 711. The limiting seat 9 provides support for the movable block 71 and allows it to move. The movable block 71 moves to lock or unlock the locking rod 711 with the limiting seat 9. The spring connecting seat 73 allows the movable block 71 to be connected to the limiting seat 9. The spring gives the movable block 71 a self-locking effect. When the movable rod 711 is in the lock hole (the spring 74 is not affected by the compressive force), the spring 74 will release its elasticity and return the movable rod 711 to the position when it is locked. That is, the locking rod 711 automatically enters the lock hole. At the same time, when locking the cover plate 6, no alignment adjustment is required. It can be done during the swinging of the cover plate 6 (the lock hole is located on the swinging path of the cover plate 6 and is on the same arc trajectory as the locking rod 711).

[0025] The end of the locking rod 711 that enters the lock hole of the limiting seat 9 has a bevel 7111. The bevel 7111 is designed so that when the locking rod 711 abuts against the limiting seat 9, the slope of the bevel 7111 and the combined thrust can cause the spring 74 to compress and deform, so that the horizontal height of the end of the locking rod 711 is lower than the horizontal height of the lock hole of the limiting seat 9. This makes it easier for the locking rod 711 to enter the lock hole during the swinging of the cover plate 6.

[0026] The cover plate 6 has an insertion hole 61 located above the movable block 71. A rotatable unlocking lever 10 is installed in the insertion hole 61. The unlocking lever 10 has a cavity for inserting an auxiliary tool. The unlocking lever 10 includes a rotating section and a lever section. The cavity is formed in the rotating section. When the auxiliary tool (a flathead screwdriver can be used) is inserted into the cavity, it can drive the rotating section to rotate. The lever rotates together with the rotating section. It rotates from top to bottom, and when it rotates about 60°, it will abut against the movable block 71. Then, by pushing the movable block 71 to adapt to its own rotation, the locking lever 711 is disengaged from the lock hole to unlock. Then the cover plate 6 can leave the guide channel 81 and release the restriction on the NFC tag sensor 5.

[0027] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
