[0025] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0026] Reference Figure 1 , a preferred embodiment of the utility model provides a subway operation safety bracket, which is used to be set on the platforms on both sides of the traffic track, including: enclosure publicity racks arranged on the platforms at intervals in sequence, connection units 2 vertically supported on the platforms and located between or on one side of adjacent enclosure publicity racks, and fastening components 5 for fastening and connecting. The enclosure publicity rack is used to play a role of safety enclosure, and is used to display warning slogans or publicity terms with set content to the public in each set time period. The two side ends of the enclosure publicity rack along the width direction are respectively plug-connected with the connection units 2 on the corresponding sides, and the fastening components 5 are plug-connected in the connection units 2 to lock the enclosure publicity rack and the connection units 2 after being plugged into place, or the fastening components 5 are used to retreat outward under the action of external force to unlock the plug-in connection between the enclosure publicity rack and the connection unit 2.

[0027] When the subway operation safety support of the utility model is working, first, a plurality of enclosure publicity racks are sequentially arranged at intervals along the extension direction of the platform, and then connecting units 2 are arranged between two adjacent enclosure publicity racks and outside the two enclosure publicity racks at the first and last ends, respectively, and a fastening component 5 is inserted into each connecting unit 2, and finally, the enclosure publicity rack or the connecting unit 2 is moved to make the adjacent enclosure publicity racks and the connecting unit 2 plug-in connected, and the plug-in connection is locked by the action of the corresponding fastening component 5, and finally, the plurality of enclosure publicity racks and the plurality of connecting units 2 are sequentially connected to form a device extending along the length direction of the platform. The safety protection bracket is used to provide safety protection for passengers on the platform. At the same time, the enclosing publicity frame is used to display warning slogans or publicity terms with set content to the public in each set time period to play a publicity and warning role. When the safety protection frame needs to be disassembled, it is only necessary to retract the fastening component 5 relative to the connecting unit 2 to unlock the plug-in connection between the enclosing publicity frame and the connecting unit 2, thereby facilitating the relative separation of the two and facilitating transportation. In the utility model, the fastening component 5 is used to realize the rapid fastening and separation of the enclosing publicity frame and the connecting unit 2, and the disassembly and assembly are simple and easy to operate.

[0028] Optionally, the enclosure publicity rack includes two plug-in blocks on both sides of the width direction thereof. A slot for accommodating the plug-in block is provided on the outer wall of the connection unit 2 corresponding to the plug-in block. The enclosure publicity rack and the connection unit 2 are connected by plugging the plug-in block into the slot, so that the two can be quickly plugged in.

[0029] Furthermore, if Figure 1 and Figure 3 As shown, the outer wall of the connection unit 2 is also provided with an installation channel which is concave and connected to the slot. The fastening assembly 5 includes a telescopic sleeve rod 502 movably arranged in the installation channel, a connecting handle 501 fixed on the outer end of the telescopic sleeve rod 502 extending out of the connection unit 2, a force plate 504 fixed on the inner end of the telescopic sleeve rod 502 extending into the slot, and a negative pressure spring 503 installed on the outer circle of the telescopic sleeve rod 502 and located between the connecting handle 501 and the force plate 504. The force plate 504 is used to press against the top of the plug-in block to retract during the process of inserting the plug-in block into the slot, thereby compressing the telescopic sleeve rod 502 and the negative pressure spring 503 so that the plug-in block continues to be inserted, and disengaging from the plug-in block after the plug-in block is inserted into place, so that the telescopic sleeve rod 502 and the negative pressure spring 503 are extended back and press against the side wall of the slot to limit the plug-in block from being out of the slot.

[0030] When the plug-in block is inserted into the slot, it first presses against and squeezes the force-bearing plate 504, and keeps squeezing the force-bearing plate 504 during a certain length of insertion. The force-bearing plate 504 retreats under the squeezing force exerted by the plug-in block, thereby axially compressing the telescopic sleeve rod 502 and the negative pressure spring 503. When the plug-in block is inserted into the slot to the required depth, the plug-in block is disengaged from the force-bearing plate 504, and the telescopic sleeve rod 502 and the force-bearing plate 504 are axially extended and reset under the action of the negative pressure spring 503. 04 abuts against the side wall of the slot, thereby limiting the plug-in block to prevent it from falling out of the slot; when it is necessary to separate the enclosure publicity frame and the connecting unit 2, it is only necessary to pull the connecting handle 501 to allow the telescopic sleeve 502 to drive the force plate 504 to retreat, thereby making way for the plug-in block to enter and exit the installation channel. At this time, the enclosure publicity frame or the connecting unit 2 can be moved to make the plug-in block withdraw from the slot, thereby realizing the rapid separation of the enclosure publicity frame and the connecting unit 2, thereby facilitating the rapid installation and transportation of the subway operation safety bracket.

[0031] Furthermore, if Figure 3As shown, the front end of the force-bearing plate 504 is provided with an inclined matching slope 5041, and the connection between the force-bearing plate 504 and the telescopic sleeve 502 forms a limiting step, which is used to abut against the wall surface at the connection between the installation channel and the slot to prevent the telescopic sleeve 502 from slipping out of the installation channel; the telescopic sleeve 502 is composed of two axially nested and connected sleeves, which is an existing conventional structure. The plug-in block includes a connecting rod and a plug-in block fixed to the front end of the connecting rod, and the plug-in block is provided with an action slope that matches the matching slope 5041, and a top abutment step is formed at the connection between the plug-in block and the connecting rod. During the insertion of the plug-in block, the plug-in block at its front end presses against the load-bearing plate 504, and at the same time, the working inclined surface on the plug-in block cooperates with the matching inclined surface 5041 on the load-bearing plate 504, so that the plug-in block can be inserted stably and smoothly. After the insertion depth of the plug-in block is in place, the plug-in block is disengaged from the abutment with the load-bearing plate 504, and the load-bearing plate 504 extends forward from the bottom of the connecting rod under the compressive elastic force of the negative pressure spring 503. At this time, the plug-in block is located at the front end of the slot depth, and the load-bearing plate 504 is located behind it, and is limited by the abutment against the step and the side of the load-bearing plate 504; when it is necessary to disassemble the enclosure publicity rack and the connecting unit 2, it is only necessary to pull the connecting handle 501 to make the telescopic sleeve rod 502 drive the load-bearing plate 504 to retreat, so as to make way for the path position of the plug-in block to enter and exit the installation channel. The operation is simple and can achieve rapid disassembly.

[0032] Alternatively, if Figure 1 As shown, the enclosure publicity rack also includes a bearing unit 1 for vertically supporting on the platform, and a publicity unit 6 rotatably mounted on the bearing unit 1. The plug-in block is vertically fixed on both ends of the width direction of the bearing unit 1. The publicity unit 6 is used to cooperate with the bearing unit 1 to protect the public, and is used to rotate within a set time interval to display different warning slogans or publicity terms to the public.

[0033] In this option, if Figure 1 As shown, the publicity unit 6 includes a plurality of warning baffles 607 arranged in sequence along the width direction of the carrier unit 1, and a driving mechanism for driving the plurality of warning baffles 607 to rotate synchronously at a set angle. The warning baffles 607 are rotatably mounted on the carrier unit 1, and the transverse section of the warning baffles 607 is a polygon. The driving mechanism is arranged in the carrier unit 1 and is respectively connected to each warning baffle 607. Figure 2 As shown, the transverse section of the warning baffle 607 is a triangle, so different warning slogans or promotional terms can be written on the three sides of the warning baffle 607 to enhance its warning and publicity effect, while also making reasonable use of the resources of the safety bracket.

[0034] In a specific embodiment of this optional solution, Figure 2As shown, the driving mechanism includes a motor 601, a rotating disk 602 connected to the output end of the motor 601, a control rod 603 arranged on the rotating disk 602, a rotatable connecting shaft 604, a matching disk 605 fixed to the end of the connecting shaft 604, and a plurality of active bevel gears 609 arranged in sequence along the length direction of the connecting shaft 604, and a plurality of driven bevel gears 606 meshing with the plurality of active bevel gears 609. The matching disk 605 is arranged corresponding to the rotating disk 602, so as to rotate under the toggle of the control rod 603 and drive the connecting shaft 604 to rotate a set angle. The plurality of driven bevel gears 606 are arranged corresponding to the plurality of warning baffles 607, and each warning baffle 607 is vertically fixed to the driven bevel gear 606 located at the bottom thereof.

[0035] When working, the motor 601 starts and drives the rotating disk 602 to rotate the set angle. During the rotation of the rotating disk 602, the control rod 603 on it drives the matching disk 605 to rotate the set angle. When the matching disk 605 rotates, it drives the connecting shaft 604 to rotate the corresponding angle. When the connecting shaft 604 rotates, it drives the multiple driving bevel gears 609 on it to rotate the set angle synchronously. When the multiple driving bevel gears 609 rotate, they drive the driven bevel gears 606 meshing with each other to rotate the set angle. Finally, when the multiple driven bevel gears 606 rotate synchronously, they drive the warning baffles 607 installed on each other to rotate through the set angle, so that multiple warning baffles 607 rotate through the same angle. In other embodiments, the output end of the motor 601 is connected to the driving gear, and the end of the connecting shaft 604 is fixed with a driven gear meshing with the external driving gear, and the force is transmitted to the connecting shaft 604 through the external meshing of the driving gear and the driven gear. In this solution, the use of the motor 601 can enable the warning baffle 607 to automatically flip over in three adjusted time periods, greatly improving the convenience of using the warning baffle 607 and the publicity effect.

[0036] like Figure 2 As shown, the promotion unit 6 also includes a mounting pad 608 disposed in the carrier unit 1 for abutting and limiting the end of the connecting shaft 604 to limit the axial position of the connecting shaft 604 .

[0037] In this option, if Figure 1 As shown, the carrying unit 1 includes an installation box for supporting on the platform, and an outer frame fixedly supported on the installation box and in the shape of a hollow square frame. The driving mechanism is arranged in the installation box. The warning baffle 607 is rotatably installed in the outer frame.

[0038] Preferably, if Figure 1 As shown, the subway operation safety bracket also includes a warning piece 4 for warning, and a colored light or a reflective component. The warning piece 4 is arranged on two vertical frame edges of the outer frame. The colored light or the reflective component is arranged on the outer frame to increase the safety of the safety bracket at night.

[0039] Preferably, if Figure 1 As shown, the subway operation safety bracket also includes a plurality of rotating plates 3 rotatably mounted on the outer frame. When strong wind blows through the subway operation safety bracket, the wind force on the surface of the outer frame will be unloaded through the rotating rotating plates 3, thereby improving the wind resistance of the entire subway operation safety bracket and ensuring its stability in use.

[0040] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
