Technical Field
[0001] The utility model relates to the technical field of subway evacuation platforms, in particular to a connection component for subway evacuation platforms. Background Art
[0002] A subway evacuation platform is a specially set up area in a subway station or subway train to safely evacuate passengers and provide necessary rescue in emergency situations such as fire, earthquake or other emergencies. Subway evacuation platforms are set up to respond to emergencies and ensure that passengers can quickly and safely leave the subway station or subway train. They play an important role in the subway system and provide passengers with a safe and orderly way to evacuate.
[0003] After searching, the publication number CN207194946U discloses a fall-proof subway evacuation platform, including an evacuation platform board, a support assembly and a guardrail assembly. The support assembly is fixed on the inner wall of the subway section tunnel to support the evacuation platform board. The guardrail assembly is arranged on the evacuation platform board. The guardrail assembly includes a vertical pole and a horizontal pole. A plurality of vertical poles are evenly spaced on the evacuation platform board. The top of each vertical pole is connected to a horizontal pole through a rotating shaft. The two horizontal poles between two adjacent vertical poles are connected by a safety lock. When the safety lock is closed, the horizontal pole between the two vertical poles is fixedly connected in a direction perpendicular to the vertical poles. In case of emergency evacuation, it can prevent evacuees from falling from the evacuation platform to the track area, and can also serve as a handrail to provide support and guidance for evacuees; when the subway makes an emergency brake at any position in the section tunnel, passengers can quickly open the safety lock corresponding to the door or the closest to the door to form a guardrail opening.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1-Figure 3The utility model provides an embodiment: a connection assembly for a subway evacuation platform, comprising a first platform 1, a hinge 3 is arranged at the bottom of the first platform 1, a second platform 2 is fixedly connected to one side of the hinge 3, the second platform 2 is connected to the first platform 1 through the hinge 3, a connection frame 4 is fixedly connected to one side of the second platform 2, a limiting groove 5 is arranged inside the connection frame 4, a connection rod 6 is fixedly connected to one side of the first platform 1, the connection rod 6 is slidably connected inside the connection frame 4, a rotating ring 7 is rotatably connected to one side of the connection rod 6, a rotating rod 8 is rotatably connected to the outer wall of the rotating ring 7, a limiting column 9 is rotatably connected to one side of the rotating rod 8, a limiting column 9 is slidably connected inside the limiting groove 5, a fixed column 10 is fixedly connected to one side of the connection rod 6, a connection assembly is arranged inside the fixed column 10, and the connection assembly comprises a hook 11, one side of the hook 11 is fixedly connected inside the fixed column 10, and the other side of the hook 11 is slidably connected to the outer wall of the rotating ring 7.
[0025] Specifically, when the evacuation platform needs to be folded, first, the hinge 3 at the bottom of the first platform 1 is rotated to drive the connecting rod 6 connected on one side to start rotating. The rotation of the connecting rod 6 further drives the connecting frame 4 connected to the outer wall to rotate. At the same time, the connecting rod 6 also transmits force through the rotating ring 7 connected to the outer wall, so that the rotating ring 7 starts to rotate. The rotating ring 7 rotates together with the rotating rod 8 connected to the outer wall. At this time, the rotation of the rotating rod 8 will also affect the sliding of the limit column 9 connected on one side inside the limit groove 5. Through the limiting effect of the limit groove 5, the limit column 9 will not slide excessively during the rotation process, but will be engaged with each other at the position matching with it inside the limit groove 5. This design can flexibly adjust the angle of platform connection according to needs to adapt to different folding needs. At the same time, when the rotating ring 7 starts to rotate, the hook 11 connected to the outer wall will also slide accordingly. When it is adjusted to the required folding angle, the movement of the hook 11 will be clamped into the outer wall of the rotating ring 7, thereby fixing the platform at the required folding position, achieving the effect of the platform being foldable.
[0026] Reference Figure 4 and Figure 5 A fixed frame 12 is fixedly connected to the top of the first platform 1 and the second platform 2, a support rod 13 is rotatably connected inside the fixed frame 12, a connecting block 14 is fixedly connected to the outer wall of the support rod 13, a rotating column 15 is rotatably connected inside the connecting block 14, a supporting frame 16 is fixedly connected to the outer wall of the rotating column 15, a railing 17 is fixedly connected to the top of the supporting frame 16, and a slider 18 is slidably connected inside the supporting frame 16.
[0027] Specifically, when the guardrail needs to be folded and extended, first, by pushing the handrail 17, the force of the handrail 17 causes the support frame 16 fixedly connected at the bottom to start moving. This action further drives the slider 18 connected internally for sliding to move. Similarly, the support frame 16 is also rotated by the rotating column 15 connected internally for rotation. The rotation of the rotating column 15 drives the support rod 13 fixedly connected to the outer wall to start rotating, and the support rod 13 further drives the connection block 14 fixedly connected to the outer wall to rotate, thereby achieving a driving effect.
[0028] Reference Figure 4 and Figure 5 A sliding column 19 is fixedly connected to the top of the slider 18, and the outer wall of the sliding column 19 is slidably connected to the inside of the railing 17. A spring 20 is sleeved on the outer wall of the sliding column 19, one end of the spring 20 is fixedly connected to the bottom of the railing 17, and the other end of the spring 20 is fixedly connected to the top of the slider 18. A handle 22 is fixedly connected to one side of the slider 18, and a clamping column 21 is fixedly connected to the bottom of the slider 18, and the clamping column 21 is in contact with the connecting block 14.
[0029] Specifically, during the movement of the slider 18 and the connecting block 14, the clamping column 21 fixedly connected to the bottom of the slider 18 contacts the connecting block 14, and this contact causes the clamping column 21 to be stressed and causes the slider 18 to slide upward. The sliding action of the slider 18 drives the spring 20 fixedly connected to the top to contract. When the slider 18 moves to a certain position, the spring 20 unloads the force and rebounds, thereby resetting the slider 18. Through the movement of the slider 18, the clamping column 21 can be inserted into the interior of the connecting block 14, thereby completing the fixing of the guardrail and achieving the effect of the guardrail being foldable.
[0030] Working principle: when the evacuation platform needs to be folded, the hinge 3 arranged at the bottom of the first platform 1 is first rotated. At this time, the first platform 1 is subjected to force to drive the connecting rod 6 with one side rotation connection to rotate, and the connecting rod 6 is subjected to force to drive the connecting frame 4 connected to the outer wall sliding connection to rotate, and at the same time, the connecting rod 6 is subjected to force to drive the rotating ring 7 with one side rotation connection to rotate, and the rotating ring 7 is subjected to force to drive the rotating rod 8 connected to the outer wall rotation connection to rotate, and the rotating rod 8 is subjected to force to drive the limiting column 9 with one side rotation connection to slide inside the limiting groove 5, and the limiting column 9 is clamped into the limiting groove 5 when rotating through the limiting groove 5, so that the effect of adjusting the platform connection angle according to needs is achieved. At the same time, when the rotating ring 7 rotates, it will drive the sliding connection hook 11 to slide. When it is adjusted to the required angle, the movement of the hook 11 is clamped into the outer wall of the rotating ring 7 to fix the platform, so as to achieve the effect of the platform being foldable. When the guardrail needs to be folded, When folding and stretching, by pushing the railing 17, the railing 17 is forced to drive the support frame 16 fixed at the bottom to move, and the support frame 16 is forced to drive the slider 18 connected internally for sliding to move. At the same time, the support frame 16 also drives the rotating column 15 connected internally for rotation, and the rotating column 15 is forced to drive the support rod 13 fixed to the outer wall to rotate, and the support rod 13 is forced to drive the connecting block 14 fixed to the outer wall to rotate. During the movement of the slider 18 and the connecting block 14, the clamping column 21 fixedly connected to the bottom of the slider 18 contacts the connecting block 14, and the clamping column 21 is forced to drive the slider 18 to slide upward, and the slider 18 is forced to drive the spring 20 fixedly connected at the top to contract. When moving to a certain position, the spring 20 unloads the force and rebounds, thereby driving the slider 18 to reset, and the slider 18 drives the clamping column 21 to snap into the inside of the connecting block 14 to fix the guardrail, thereby achieving the effect of the foldable guardrail.
