Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a handrail for rail transportation. Background Art

[0002] With the development of the times, people's living standards are constantly improving. Subways have been widely used in medium and large cities.

[0003] At present, the handrails in the carriage are installed on the handrails, and the height of the handrails is fixed. Primary school students or middle school students with developmental delays can only hold the handrails. However, in order to ensure the strength of the handrails, the diameter of the handrails is generally thicker. The palms of the students cannot fully hold the handrails, and they are easy to slip out of their hands, resulting in the students being unable to stabilize their bodies by holding the handrails. In general, the connecting parts are first installed on the handrails, and then the fixing ropes on the handrails are installed on the connecting parts. The connecting parts are generally made of metal, while the handrails and the fixing ropes are made of plastic and cotton cloth respectively. They are easily damaged after being used for a period of time and need to be replaced. At present, the connecting parts need to be disassembled to replace the handrails, which is inconvenient to replace. Utility Model Content

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0021] In one embodiment, Figure 1-4 As shown, a rail transit handrail comprises a handrail 1, a plurality of jacks 2 are provided on the front and rear sides of the surface of the handrail 1, the plurality of jacks 2 are linearly arranged in sequence from top to bottom, a plurality of connecting rings 3 are movably sleeved on the outer surface of the handrail 1, the plurality of connecting rings 3 are linearly arranged in sequence from top to bottom, a positioning mechanism 4 is provided on the connecting ring 3, a mounting mechanism 5 is provided on the left side of the connecting ring 3, a plastic handrail 6 is provided at the bottom of the mounting mechanism 5, a fixing rope 7 is fixedly connected to the top of the plastic handrail 6, a connecting groove is provided at the upper end of the inner side of the fixing rope 7, and a mounting tube 8 is fixedly sleeved in the connecting groove.

[0022] In order to facilitate the fixation of the connecting ring 3 on the handrail 1, the positioning mechanism 4 includes a connecting tube 41. There are two connecting tubes 41, and the two connecting tubes 41 are respectively fixedly connected to the middle of the front and rear sides of the connecting ring 3. An insertion rod 42 is movably sleeved in each connecting tube 41. One end of the two insertion rods 42 is respectively movably sleeved on the front and rear sides of the connecting ring 3 and inserted into adjacent sockets 2. The other end of the insertion rod 42 is movably sleeved on the end of the connecting tube 41 away from the connecting ring 3 and penetrates to the outside of the connecting tube 41. The end face of the insertion rod 42 away from the connecting ring 3 is fixedly connected to a pull ring 43.

[0023] In order to enable the insertion rod 42 to automatically reset and be inserted into the socket 2 after being pulled outward, a fixing block 44 is fixedly sleeved in the middle of the surface of the insertion rod 42, and the fixing block 44 is movably sleeved in the inner cavity of the connecting tube 41. A spring 45 is sleeved in the middle of the surface of the insertion rod 42, and one end of the spring 45 is fixedly connected to a side of the fixing block 44 away from the connecting ring 3, and the other end of the spring 45 is fixedly connected to a side of the inner wall of the connecting tube 41 away from the connecting ring 3.

[0024] In order to facilitate the installation and disassembly of the fixing rope 7, the installation mechanism 5 includes a mounting block 51, the right side of the mounting block 51 is fixedly connected to the left side of the connecting ring 3, the inner cavity of the mounting block 51 is provided with a mounting groove 52, the upper end of the fixing rope 7 is sleeved in the mounting groove 52, and a threaded hole is provided on the left side of the mounting block 51, a fixing rod 53 is threadedly sleeved in the threaded hole, the middle part of the fixing rod 53 passes through the mounting groove 52, the middle part of the fixing rod 53 is movably sleeved in the mounting tube 8, and the left end face of the fixing rod 53 is fixedly connected with a knob 54.

[0025] In order to support the right end of the fixing rod 53 and prevent the left end of the fixing rod 53 from being broken due to excessive downward pressure, a connecting hole 55 is opened on the right side of the mounting groove 52, and the right end of the fixing rod 53 is inserted into the connecting hole 55. After the right end of the fixing rod 53 is inserted into the connecting hole 55, the right end is unlikely to bend downward.

[0026] In order to allow the fixing rope 7 to be inserted into the mounting groove 52 from the bottom of the mounting block 51 , a slot is provided at the bottom of the inner mounting block 51 , the slot is communicated with the mounting groove 52 , and the middle portion of the fixing rope 7 is inserted into the slot.

[0027] In order to conveniently fix the upper and lower ends of the handrail 1 to the top and bottom of the carriage respectively, the top and bottom of the handrail 1 are fixedly connected with fixing plates 9, and each fixing plate 9 has assembly holes at the four corners, and assembly screws 10 are inserted into the assembly holes.

[0028] Working principle: When the utility model is used, first pull the pull ring 43, the pull ring 43 drives the insertion rod 42 to move, so that the insertion rod 42 is pulled out from the socket 2, thereby releasing the fixation of the connecting ring 3, and then adjust the connecting ring 3 up and down, the connecting ring 3 drives the plastic handrail 6 to move up and down, and the plastic handrail 6 is adjusted to a position suitable for the user on the handrail 1, and then release the pulled pull ring 43, the spring 45 will push the fixing block 44 to move, and the fixing block 44 drives the insertion rod 42 to move, so that the insertion rod 42 is inserted into the socket 2 at the corresponding position, and the connecting ring 3 is fixed, so that the connecting ring 3 cannot move up and down, thereby completing the position adjustment of the plastic handrail 6, so that people with shorter height such as students can also hold the plastic handrail 6 to keep the body stable in the car without holding the handrail 1, thereby improving the practicality of the device, when it is necessary to replace the plastic handrail 6 or the fixing rope 7, first twist the rotary The fixing rod 53 is then pulled out of the mounting tube 8 and the plastic handrail 6 is removed from the connecting ring 3. When installing the plastic handrail 6, the top of the fixing rope 7 of the plastic handrail 6 is first inserted into the mounting groove 52 through the slot, and the mounting tube 8 is oriented left and right. Then, the knob 54 is twisted in the opposite direction to move the fixing rod 53 to the right and insert it into the mounting tube 8 to fix the fixing rope 7 so that the fixing rope 7 cannot be separated from the mounting groove 52 until the right end of the fixing rod 53 is inserted into the connecting hole 55. The installation of the plastic handrail 6 is completed in this way.

[0029] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
