Description

Technical Field

[0001] The utility model relates to the technical field of subway hanging rings, in particular to a subway hanging ring buffer structure. Background Art

[0002] Subway hanging rings refer to the hanging rings inside the subway car, which are used by passengers to hold on to and stabilize their bodies. Subway hanging rings are usually installed on the top of the car. Passengers can hold on to the hanging rings to maintain balance and prevent shaking or loss of balance during travel. The sudden acceleration and braking of the subway may cause passengers to be subjected to greater impact when holding the hanging rings, causing discomfort or injury, so a hanging ring buffer structure is needed.

[0003] When the subway is running, sudden acceleration and braking will cause changes in speed, which will cause passengers inside to become unstable and fall. Traditional subway hanging rings are mostly made of ring-shaped hard plastic and fixed to the roof with ropes. They cannot provide cushioning and are easy to cause certain injuries to passengers' wrists and arms. Passengers usually need to hold the hanging rings for a long time to maintain balance during peak hours. However, the traditional hanging ring structure does not take hand comfort into consideration. Holding the hanging rings for a long time may cause hand fatigue and discomfort. Utility Model Content

When the passenger's body tilts, the passenger will generate a pulling force on the handle, which will drive the connecting plate to move downward along the direction of the sliding groove, so that the second slider moves downward to stretch the damper, and under the action of the damper, the handle is initially buffered.

[0008] As a further scheme of the utility model, the second buffer mechanism includes a first connecting block, two first fixing plates are fixed on the inner side wall of the frame, the first connecting block and the two first fixing plates are rotatably connected, a sleeve is fixed on the side wall of the first connecting block, and the inner side wall of the sleeve is slidably connected to the first sliding block, a connecting rod is fixed on the top of the first sliding block, and one end of the connecting rod passes through the top of the sleeve, a second buffer spring is sleeved on the side wall of the connecting rod, and the second buffer spring is located inside the sleeve, and two second fixing plates are fixed on the side wall of the rectangular block, and the inner side walls of the two second fixing plates are rotatably connected to the same second connecting block, and the connecting plate and one end of the connecting rod are fixed, when the connecting plate moves downward and drives the pull rod to move downward, the matching card block drives the rectangular block to move downward, and the rectangular block moves downward to cooperate with the second fixing plate and the second connecting block to make the sleeve tilted and drive the connecting rod to gradually extend. At this time, under the action of the first sliding block, the second buffer spring gradually becomes compressed, and under the reaction force of the second buffer spring in the compressed state, the handle is buffered for the second time, further improving the buffering effect.

[0009] As a further solution of the utility model, a connecting ring is fixed on the top of the frame, and the connecting ring can connect the device to the roof of the subway car through a rope.

A first buffer mechanism for buffering the connecting plate 19 is symmetrically provided at both ends of the inner wall of the frame 1, a baffle 7 is fixed on the inner wall of the frame 1, and the baffle 7 is located above the connecting plate 19, a pull rod 15 is fixed in the middle of the top of the connecting plate 19, and the pull rod 15 runs through the top of the baffle 7, a first buffer spring 16 is sleeved on the side wall of the pull rod 15, a rectangular block 13 is provided on the top of the baffle 7, and the rectangular block A through hole 8 is provided on the top of 13, and the through hole 8 is sleeved on the side wall of the pull rod 15. A clamping block 14 is fixed on the top of the pull rod 15. Second buffer mechanisms for buffering the pull rod 15 are provided at both ends of the rectangular block 13. During use, the device provides passengers with a more comfortable touch through the rubber pad 23 and the convex setting on it, reduces the discomfort caused by the passenger holding the handle 11 for a long time, and when the passenger's body falls, the passenger will generate a pulling force on the handle 11. During the pulling process, the handle 11 is buffered by the first buffer mechanism and the second buffer mechanism, thereby improving the buffering effect and avoiding damage to the passenger's body.

[0022] Reference Figure 4 and Figure 5 In a preferred embodiment, the first buffer mechanism includes a second slider 21, which is fixed to one end of the connecting plate 19. A slide groove 20 is provided on the inner side wall of the frame 1, and the second slider 21 is slidably connected to the slide groove 20. A damper 22 is fixed to the top of the slide groove 20, and the output end of the damper 22 is fixed to the second slider 21. When the passenger's body falls, the passenger will generate a pulling force on the handle 11, which will drive the connecting plate 19 to move downward along the direction of the slide groove 20, so that the second slider 21 moves downward to stretch the damper 22. Under the action of the damper 22, the handle 11 is initially buffered.

[0023] Reference Figure 1 and Figure 2In a preferred embodiment, the second buffer mechanism includes a first connecting block 4, two first fixing plates 3 are fixed to the inner side wall of the frame 1, the first connecting block 4 and the two first fixing plates 3 are rotatably connected, a sleeve 5 is fixed to the side wall of the first connecting block 4, a first slider 18 is slidably connected to the inner side wall of the sleeve 5, a connecting rod 6 is fixed to the top of the first slider 18, and one end of the connecting rod 6 passes through the top of the sleeve 5, a second buffer spring 17 is sleeved on the side wall of the connecting rod 6, and the second buffer spring 17 is located inside the sleeve 5, two second fixing plates 10 are fixed to the side wall of the rectangular block 13, and the two second fixing plates 1 0The inner wall is rotatably connected with the same second connecting block 9, and the connecting plate 19 and one end of the connecting rod 6 are fixed. When the connecting plate 19 moves downward and drives the pull rod 15 to move downward, the matching block 14 drives the rectangular block 13 to move downward. The rectangular block 13 moves downward and cooperates with the second fixed plate 10 and the second connecting block 9 to make the sleeve 5 tilt and drive the connecting rod 6 to gradually extend. At this time, under the action of the first slider 18, the second buffer spring 17 is gradually compressed. Under the reaction force of the second buffer spring 17 in the compressed state, the handle 11 is buffered for a second time, which further improves the buffering effect.

[0024] Reference Figure 1 In a preferred embodiment, a connecting ring 2 is fixed on the top of the frame 1, and the connecting ring 2 can connect the device to the roof of the subway car through a rope.

[0025] Reference Figure 1 and Figure 4 In a preferred embodiment, buffer pads 12 are fixed at both ends of the bottom of the frame 1. The buffer pads 12 can prevent the connecting plate 19 and the frame 1 from having a hard collision, thereby avoiding collision damage to the equipment and having a buffering effect to avoid causing harm to the passengers.

[0026] Working principle of this embodiment: During use of this device, the connecting ring 2 is pre-connected to the roof of the subway car through a rope. When in use, the passenger holds the handle 11. Since the handle 11 is provided with a rubber pad 23 and the rubber pad 23 is provided with a protrusion, when the passenger holds the rubber pad 23, it fits the hand shape more closely, and the rubber pad 23 will undergo a certain deformation when squeezed by an external force, providing the passenger with a more comfortable touch and reducing the discomfort caused by the passenger holding the handle 11 for a long time. When the subway vibrates, the passenger will generate a pulling force on the handle 11, which will drive the connecting plate 19 to move downward along the direction of the slide groove 20, so that the second slider 21 moves downward to stretch the damper 22. Under the action of the damper 22, the handle 11 is initially buffered, and the connecting plate 19 moves downward, driving the pull rod 15 to move downward to cooperate with the baffle 7 to compress. The first buffer spring 16, under the reaction of the first buffer spring 16 in the compressed state, slows down the speed of the pull rod 15 moving downward, and the pull rod 15 continues to move downward, and cooperates with the block 14 to drive the rectangular block 13 to move downward. The rectangular block 13 moves downward and cooperates with the second fixed plate 10 and the second connecting block 9 to make the sleeve 5 tilt and drive the connecting rod 6 to gradually extend. At this time, under the action of the first slider 18, the second buffer spring 17 gradually becomes compressed. Under the reaction force of the second buffer spring 17 in the compressed state, the handle 11 is buffered for the second time, which further improves the buffering effect. When the two ends of the bottom of the connecting plate 19 are respectively in contact with the two buffer pads 12, a hard collision between the connecting plate 19 and the frame 1 is avoided, which can not only avoid collision damage to the equipment, but also have a buffering effect again to avoid harm to the passengers' bodies.
