Description

Technical Field

[0001] The invention belongs to the technical field of vehicle accessories, and in particular relates to a handrail for a rail transit vehicle. Background Art

[0002] In people's daily lives, rail transit has become an indispensable green mode of public transportation. The passenger compartment modules of existing rail transit vehicles usually have a column handrail at the entrance area, but when there is a large passenger flow and the vehicle passenger compartment module is fully loaded, because there is only one column handrail, only passengers close to the column handrail can hold on, and most passengers in the door area cannot actually hold on to the fixed handrail, which will bring certain risks to these passengers. How to provide more passengers with better grip needs, improve standing stability and bring higher riding safety has become a technical problem that needs to be solved this time. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a rail transit vehicle handrail that can meet the grasping needs of more passengers and improve people's riding safety.

When the armrest base is pressed, the pressure is transmitted to the clamping piece through the oil pressure pipeline, driving the clamping piece to be squeezed toward the inner side of the shaft seat, so that the clamping piece and the shaft seat are tightly abutted due to friction resistance to fix the position between the rotating shaft and the shaft seat.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following Figure 1-Figure 3 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] The present invention discloses a handrail for a rail transit vehicle, which is usually used in conjunction with a column on a public transportation vehicle. The handrail includes an axle seat 1, a rotating shaft assembly, a clamping member 5, and an armrest base 4. The axle seat is used to be fixedly connected to the column on the rail transit vehicle and is arranged in a ring shape. In this embodiment, the inner side of the axle seat 1 is connected to the column by welding. The axle seat 1 includes an axle seat body 11 and an axle seat ring 12 connected to the lower end of the axle seat body 11 by bolts 13. The cross-section of the axle seat is in the shape of an "I".

[0017] The rotating shaft assembly is loosely sleeved on the shaft seat 1. In the absence of external interference, the rotating shaft assembly can rotate around the shaft seat 1. In practical applications, the rotation also ensures the needs of dynamic passenger flow in the vehicle to better provide the grasping needs of passengers in different positions.

[0018] The rotating shaft assembly includes a rotating shaft 2 sleeved on the shaft seat body 11 and an arm 3 connected to the rotating shaft 2. The arm 3 can be provided with multiple arms according to needs and arranged on the rotating shaft 2 in a circumferential manner. The arm 3 and the rotating shaft 2 are connected by threads, and a hydraulic pipeline is arranged in the rotating shaft assembly; further, a first hydraulic pipeline 31 is arranged in the arm 3, and a ring-shaped second hydraulic pipeline 21 is arranged in the rotating shaft 2. When the arm 3 is connected to the rotating shaft, the first hydraulic pipeline 31 and the second hydraulic pipeline 21 will be connected. The first hydraulic pipeline 31 and the second hydraulic pipeline 21 are respectively formed by the cavities in the arm 3 and the rotating shaft 2. The second hydraulic pipeline 21 is arranged in a ring shape, and the first hydraulic pipeline 31 is in a straight line.

[0019] The clamping member 4 is placed on the inner side of the rotating shaft end where the shaft arm is located. Specifically, the rotating shaft is provided with a through hole that vertically penetrates the second oil pressure pipeline 21. The clamping member 4 is placed at the inner end of the through hole, and the outer end of the through hole is built with a thread for connecting with the shaft arm 3. The clamping member 4 is a damping rubber member. The number of the clamping members 5 corresponds to the number of the shaft arms 3.

[0020] The handrail base 4 is placed on the shaft arm 3, and one end of the handrail base 4 is connected to the oil pressure pipeline, that is, one end of the handrail base 4 is movably extended into the first oil pressure pipeline 31 in the shaft arm 3. The number of the handrail bases 4 can be adjusted as needed. Each handrail base is connected in series with the oil pressure pipeline. A grab rope insertion hole 41 is provided on the handrail base 4, and a grab rope is set in the grab rope insertion hole, and a grab handle is added to facilitate passengers to hold.

[0021] The handrail of the present invention is usually welded to the upper end of the column to avoid occupying the passenger standing space too low. The rotation stop system is realized by combining the hydraulic oil circuit of the hydraulic pipeline. Specifically, since the rotating shaft 2 and the shaft seat 1 can complete the circumferential rotation without the action of external force, the passengers can rotate the shaft arm as needed to hold the handrail. When holding the handrail, the pressure will be transmitted to the clamping member 5 through the hydraulic pipeline to drive the clamping member 5 to squeeze the inner side of the shaft seat 1, so that the clamping member 5 and the shaft seat 1 are closely abutted due to friction resistance, thereby achieving the position fixation between the rotating shaft and the shaft seat, and realizing the shaft arm stopping rotation at the desired position.

[0022] A plurality of shaft arms can be arranged on one shaft, which can be used by passengers in different positions and directions. At the same time, a plurality of handrail bases 4 can be arranged on one shaft arm. When more handrail bases 4 are used, the pressure in the oil pressure pipeline will be greater, thereby enhancing the stability of the rotation stop position.

[0023] In order to better understand the present invention, the following is an explanation of the assembly principle of the oil circuit of the present invention: First, the rotating shaft 2 and the shaft arm 3 are connected, and the connection between the two is through a threaded connection, and the sealing between the rotating shaft and the pipeline in the shaft arm can be achieved by a conventional sealing gasket, etc. After the two are assembled, the oil in the hydraulic pipeline is filled, and the filling can be done by injecting the oil through the connection hole opened on the shaft arm 3 for connecting with the handrail base 4, and finally the entire oil pipeline is sealed through the connection with the handrail base 4.

[0024] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] There are many specific application examples of the present invention. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
