A type of subway car handrail

Abstract

This utility model discloses a subway car handrail, including a fixing component, a flexible connecting strip connected to the bottom of the fixing component, and a handle connected to the bottom of the flexible connecting strip. Linear sliding holes are vertically arranged on both sides of the handle, and sliding rods are slidably connected within the linear sliding holes. Hooks are provided at the top of the sliding rods, and the bottoms of the two sliding rods are connected by a pull rod. Pulling the pull rod downwards causes it to slide downwards within a groove, moving the two sliding rods downwards within the linear sliding holes. A spring is provided between the bottom of the sliding rod and the bottom of the linear sliding hole. Through the elastic connection between the sliding rod and the handle, when the pull rod is pulled downwards, the hook can hook onto the handrail crossbar, making the handle and handrail crossbar a rigid connection, saving passengers' energy and preventing swaying and potential collisions. When the pull rod is released, the hook moves upwards and disengages from the handrail crossbar, making the handle and handrail crossbar a flexible connection, preventing injury to passengers and improving passenger safety.

Description

Technical Field

[0001] This utility model belongs to the field of subway equipment technology, and in particular relates to a subway car handle. Background Technology

[0002] In some medium and large cities, subways have become an important mode of transportation. To help standing passengers maintain their balance and increase the number of handrails in crowded environments to prevent falls or collisions due to inertia, handrails are installed in the aisles of the carriages.

[0003] To prevent passengers from colliding with handrails and getting injured while walking, traditional handrails are suspended from the handrail crossbar by ropes or chains. The suspension design can cushion collisions and reduce injury to passengers. However, when a vehicle accelerates, decelerates, or turns, it will sway significantly. The flexible connection between the handrail and the handrail crossbar requires passengers to use a lot of arm strength and inertia to counteract the movement, making it difficult to maintain balance. The body will sway with inertia, making it easy to bump into things. Therefore, there is a need to design a handle that is rigidly connected to the handrail crossbar when in use to improve passenger stability and prevent bumps caused by swaying, and is flexible when not in use to prevent injury to passengers. This would be both practical and safe. Utility Model Content

[0004] The purpose of this invention is to achieve a flexible connection between the handle and the lever by elastically connecting the lever and the handle. This allows the lever to be pulled down, the hook to catch the handrail, and the handle to become rigidly connected to the handrail. When the lever is released, the hook moves upward and detaches from the handrail, making the handle and handrail flexiblely connected. This addresses the problems in the prior art where a rigid connection between the handle and the handrail easily leads to collisions and injuries to passengers, while a flexible connection requires passengers to exert a great deal of force and overcome inertia, making it difficult to maintain balance and causing the body to sway due to inertia, which can easily result in collisions.

[0005] The specific technical solution of this utility model is as follows:

[0006] A subway car handrail includes a fixing component with a flexible connecting strip at the bottom and a handle at the bottom of the flexible connecting strip. Linear sliding holes are vertically provided on both sides of the handle, and sliding rods are slidably connected within the linear sliding holes. Hooks are provided at the top of the sliding rods, and the bottoms of the two sliding rods are connected by a pull rod. Hand grip holes are provided between the two linear sliding holes, penetrating the handle from front to back. Vertical surfaces are provided on both sides of the hand grip holes, and vertical grooves adapted to the pull rods are provided on the vertical surfaces. The grooves communicate with the linear sliding holes. Pulling the pull rod downwards causes it to slide downwards within the grooves, moving the two sliding rods downwards within the linear sliding holes. A spring is provided between the bottom of the sliding rod and the bottom of the linear sliding hole.

[0007] Furthermore, the flexible connecting strip is a ring-shaped strip made of nylon, with two fixing rods inside the ring-shaped strip. One fixing rod is wrapped inside the top of the ring-shaped strip, and the other fixing rod is wrapped inside the bottom of the ring-shaped strip.

[0008] Furthermore, the upper part of the handle is provided with a lower fixing groove, which is adapted to the fixing rod. The top of the lower fixing groove is provided with a lower through groove, which is adapted to the flexible connecting strip. The bottom of the lower through groove is connected to the top of the lower fixing groove, and the top of the lower through groove penetrates through the upper surface of the handle.

[0009] Furthermore, the handle has a groove located between the lower fixing groove and the hand grip hole, and the handle is made of transparent acrylic.

[0010] Furthermore, the handle includes a front handle and a rear handle, which are identical in shape. The front handle and the rear handle are provided with several threaded holes, and the front handle and the rear handle are fixedly connected by the engagement of screws with the threaded holes.

[0011] Furthermore, the fastener has an internal mounting through hole.

[0012] Furthermore, an upper fixing groove is provided near the lower part of the mounting through hole, and an upper through groove is provided at the bottom of the upper fixing groove. The top of the upper through groove is connected to the bottom of the upper fixing groove, and the bottom of the upper through groove penetrates the lower surface of the fixing component.

[0013] Furthermore, the fastener includes an upper clamping block and a lower clamping block, and the upper clamping block and the lower clamping block are respectively provided with several threaded holes. The upper clamping block and the lower clamping block are fixedly connected by the cooperation of screws and threaded holes.

[0014] Furthermore, the upper fixing groove and the upper through groove are located inside the lower clamping block. The lower clamping block includes a front clamping block and a rear clamping block. The front clamping block and the rear clamping block have the same shape. The front clamping block and the rear clamping block are respectively provided with several threaded holes. The front clamping block and the rear clamping block are fixedly connected by the cooperation of screws and threaded holes.

[0015] Furthermore, a gripping component is fixedly fitted onto the pull rod, with several gripping grooves on the upper surface of the gripping component and several finger grooves on the lower upper surface of the hand grip hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When passengers use the handrail, they pull down on the grip piece, aligning the lower surface of the grip piece with the upper surface of the handgrip hole, and then hold it. At this point, the hook engages with the handrail bar. The handrail and handrail bar are connected by a sliding rod, avoiding swaying caused by the flexible connection. This reduces the force of the passenger's arm against inertia, making it easier for passengers to maintain their balance when the vehicle accelerates, decelerates, or turns. It saves passengers' energy and reduces body swaying, preventing collisions with other people or objects in the carriage, thus improving the safety and practicality of using the handrail. When the handrail is not in use, the spring pushes the sliding rod upward, causing the hook to disengage from the handrail bar. At this point, the handrail and handrail bar are connected by a flexible connecting strip. If a passenger bumps into the handrail while walking, the flexible connection between the handrail and handrail bar causes the handrail to sway during the collision, which can dissipate the reaction force exerted by the handrail on the passenger during the collision, preventing passenger injury and improving the safety of passengers riding the subway.

Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] See Figures 1 to 5This embodiment discloses a subway car handrail, including a fixing member 1, which is installed on the handrail crossbar. A flexible connecting strip 2 is connected to the bottom of the fixing member 1, and a handle 3 is connected to the bottom of the flexible connecting strip 2. Linear sliding holes 31 are vertically provided on the left and right sides of the handle 3, and a sliding rod 4 is slidably connected within the linear sliding holes 31. A hook 41 is provided at the top of the sliding rod 4 to hook onto the handrail crossbar. The sliding rod 4 is made of stainless steel. Further optimization is possible by making the hook 41 at the top of the sliding rod 4 integrally bent. The high strength of stainless steel ensures that the hook 41... 1. It will not be deformed by passengers pulling it. The contact surface between the hook 41 and the handrail crossbar is set as a flat surface, and a rubber anti-slip pad is pasted on the flat surface to increase the stability of the handle 3 during use. The bottom of the two sliding rods 4 are connected by a pull rod 42. The pull rod 42 is set horizontally. A hand grip hole 32 is provided between the two linear sliding holes 31, which runs through the handle 3. Vertical surfaces 321 are provided on both sides of the hand grip hole 32. Vertical grooves 322 that fit the pull rod 42 are provided on the vertical surfaces 321. The pull rod 42 can slide up and down in the grooves 322. The grooves 322 are connected to the linear sliding holes 31. The pull rod 42 can... The slide rod 4, passing through the slide groove 322 and connected to the linear slide hole 31, can be further optimized by welding the slide rod 4 and the pull rod 42 together, increasing the strength between them. When the pull rod 42 is pulled down, it slides downward in the slide groove 322, causing the two slide rods 4 to move downward in the linear slide hole 31. At this time, the hook 41 hooks onto the handrail crossbar, and the handle 3 is connected to the handrail crossbar through the slide rod 4. This avoids the swaying caused by the flexible connecting strip 2, reduces the force of the passenger's arm against inertia, and makes it easier for the passenger to accelerate, decelerate, or turn the vehicle. Maintaining body balance saves passengers' energy and reduces the occurrence of accidents. A spring 5 is installed between the bottom of the slide bar 4 and the bottom of the linear slide hole 31. When the handle 3 is not in use, the spring 5 pushes the slide bar 4 upward, causing the hook 41 to disengage from the handrail. At this time, the handle 3 and the handrail are connected by a flexible connecting strip 2. If a passenger bumps into the handle 3 while walking, the flexible connection between the handle 3 and the handrail causes the handle 3 to shake during the collision, which can dissipate the reaction force exerted by the handle 3 on the passenger during the collision, prevent the passenger from being injured, and improve the safety of passengers taking the subway.

[0032] The flexible connecting strip 2 is a ring-shaped strip made of nylon. There are two fixing rods 21 inside the ring-shaped strip. One fixing rod 21 is wrapped inside the top of the ring-shaped strip, and the other fixing rod 21 is wrapped inside the bottom of the ring-shaped strip.

The flexible connecting strip 2 passes through the lower through groove 34 and connects upward to the fixing member 1.

[0034] The handle 3 has a groove 35, which is located between the lower fixing groove 33 and the hand grip hole 32. The handle 3 is made of transparent acrylic. An advertising card can be placed in the groove 35, which is convenient for merchants to place advertisements.

[0035] The handle 3 includes a front handle 36 and a rear handle 37. The front handle 36 and the rear handle 37 have the same shape. The handle 3 is composed of the front handle 36 and the rear handle 37 mirror images of each other, which makes it convenient to place the advertising card, the flexible connecting strip 2, the fixing rod 21, the sliding rod 4 and the pull rod 42 into the groove 35, the lower through groove 34, the lower fixing groove 33, the linear sliding hole 31 and the sliding groove 322 inside the handle 3, respectively. The front handle 36 and the rear handle 37 are provided with several threaded holes. The front handle 36 and the rear handle 37 are fixedly connected by the cooperation of the screw and the threaded holes.

[0036] The fixing component 1 has an internal mounting through hole 11, which is fitted onto the handrail crossbar to connect the fixing component 1 to the handrail crossbar. The inner wall of the mounting through hole 11 is covered with a rubber anti-slip pad to increase the stability of the fixing component 1 on the handrail crossbar and prevent slippage.

[0037] An upper fixing groove 12 is provided near the lower part of the mounting through hole 11. An upper through groove 13 is provided at the bottom of the upper fixing groove 12. The top of the upper through groove 13 is connected to the bottom of the upper fixing groove 12. The bottom of the upper through groove 13 passes through the lower surface of the fixing member 1. A fixing rod 21 is wrapped around the inner side of the top of the annular band and placed in the upper fixing groove 12 to realize the connection between the fixing member 1 and the flexible connecting band 2. The flexible connecting band 2 passes through the upper through groove 13 and connects downward to the handle 3.

[0038] The fastener 1 includes an upper clamping block 14 and a lower clamping block 15. The fastener 1 is composed of the upper clamping block 14 and the lower clamping block 15, which are fitted together to facilitate installation on the handrail crossbar. The upper clamping block 14 and the lower clamping block 15 are provided with several threaded holes. The upper clamping block 14 and the lower clamping block 15 are fixedly connected by the cooperation of screws and threaded holes.

[0039] The upper fixing groove 12 and the upper through groove 13 are located inside the lower clamping block 15. The lower clamping block 15 includes a front clamping block 151 and a rear clamping block 152. The front clamping block 151 and the rear clamping block 152 have the same shape. The lower clamping block 15 is composed of the front clamping block 151 and the rear clamping block 152 mirror images of each other, which makes it convenient to place the fixing rod 21 and the flexible connecting strip 2 in the upper fixing groove 12 and the upper through groove 13 respectively. The front clamping block 151 and the rear clamping block 152 are provided with several threaded holes. The front clamping block 151 and the rear clamping block 152 are fixedly connected by the cooperation of the screws and the threaded holes.

[0040] A gripper 43 is fixedly sleeved on the pull rod 42. The upper surface of the gripper 43 is provided with several grip grooves 431, and the bottom upper surface of the hand grip hole 32 is provided with several finger grooves 323. Both the grip grooves 431 and the finger grooves 323 are concave grooves. In this embodiment, four grip grooves 431 and four finger grooves 323 are arranged in a linear array along the horizontal direction, which can fit with the fingers to improve grip stability and comfort.

[0041] Working principle: When a passenger uses handle 3, they pull on the grip piece 43 and pull it downwards, so that the lower surface of the grip piece 43 is in contact with the bottom upper surface of the hand grip hole 32, and they hold it in their hand. At this time, the hook 41 hooks onto the handrail bar. Handle 3 and handrail bar are connected by the slide bar 4, which avoids the shaking caused by the flexible connecting strip 2, reduces the force of the passenger's arm against inertia, and makes it easier for the passenger to control their body balance when the vehicle accelerates, decelerates or turns. This saves the passenger's energy and also reduces the occurrence of physical collisions. When handle 3 is not in use, the spring 5 pushes the slide bar 4 upwards, so that the hook 41 is disengaged from the handrail bar. At this time, handle 3 and handrail bar are connected by the flexible connecting strip 2. If a passenger bumps into handle 3 while walking, the flexible connection between handle 3 and handrail bar causes handle 3 to shake during the collision, which can absorb the impact force of the collision and dissipate the reaction force exerted by handle 3 on the passenger during the collision, preventing the passenger from being injured and improving the safety of passengers riding the subway.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
