Description

Technical Field

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

[0002] Handrails for rail transit vehicles are an important device that provides support and stability for passengers. The design and installation of handrails need to take into account the comfort and safety of passengers, and must also comply with relevant standards and specifications.

[0003] Vehicle disinfection requires disinfection of the handrail structure. The disinfectant has a certain degree of corrosiveness and is corrosive to the handrail mounting seat. Over time, the threads are corroded and rusted and cannot be disassembled for cleaning. Some dead corners of the fixed seat cannot be cleaned at all. Over a long period of time, rust is generated. During the next vehicle maintenance, the threads are oxidized and rusted. The column handrail is difficult to disassemble during vehicle maintenance and is not waterproof and corrosion-resistant. Based on these problems, Chinese patent CN218750776U discloses a subway column handrail mounting structure, in which the handrail base is clamped inside the cup cover through a cup cover. During the disassembly process, it is only necessary to squeeze the lower rubber ring clamped between the semicircular boss and the handrail mounting seat. The deformation of the lower rubber ring realizes the separation of the cup cover and the handrail base, and realizes quick disassembly, installation and maintenance. The upper rubber ring accommodated in the first semicircular groove on the top of the cup cover and the lower rubber ring clamped between the handrail mounting seat and the semicircular boss can effectively prevent external moisture and corrosive liquid from seeping into the base and corroding the base threads.

[0004] The mounting base of the column handrail in the device is mainly installed on the floor inside the rail transit vehicle, so the position of the cup body assembly is relatively low and it is easily kicked by the passengers' feet. When the lower rubber ring is deformed due to external collision, the cup cover will automatically detach from the handrail base. At this time, the bolt connection structure is not only exposed to affect the aesthetics, but also causes the bolt connection structure to be corroded by dust and water stains.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0035] Reference Figure 1-7 The utility model provides an embodiment: a handrail structure for a rail transit vehicle, including a mounting seat 1, a cavity 2 running through the mounting seat 1 from top to bottom, a first threaded sleeve 3 fixedly connected to the bottom end of the inner wall of the cavity 2, a long axis bolt 4 threadedly connected to the inner wall of the first threaded sleeve 3, and the mounting seat 1 can be fixed to the floor of the rail transit vehicle by using the connection structure between the long axis bolt 4 and the first threaded sleeve 3. The top ends of the mounting seat 1 are welded with an insertion shaft 5, and the outer wall of the insertion shaft 5 is sleeved with an armrest seat 6. The bottom ends of the armrest seat 6 are provided with vertical through holes, and the outer wall of the insertion shaft 5 is vertically inserted upward. The armrest seat 6 is inserted into the through hole and the installation position of the armrest seat 6 can be limited by setting the insertion shaft 5. A rubber pad 7 is bonded at the center of the bottom of the armrest seat 6. A pad 8 is fixedly connected to the bottom of the rubber pad 7. By setting the rubber pad 7 and the pad 8 structure, the top of the long-axis bolt 4 can be pressed, which is beneficial to improve the stability of the long-axis bolt 4. When the bottom surface of the pad 8 contacts the top surface of the long-axis bolt 4, the armrest seat 6 continues to move downward to deform the rubber pad 7. At this time, the contact position of the pad 8 and the long-axis bolt 4 can be made closer. The outer walls of the rubber pad 7 and the pad 8 are both sleeved with the top of the inner wall of the cavity 2.

[0036] A second threaded sleeve 9 is fixedly connected to the center of the outer wall on both sides of the mounting seat 1, and a sleeve 10 is sleeved on the outer wall of the second threaded sleeve 9. A retaining ring 11 is fixedly connected to one end of the inner wall of the sleeve 10. A threaded shaft 12 runs through the inner wall of the retaining ring 11, and one end of the outer wall of the threaded shaft 12 is threadedly connected to the inner wall of the second threaded sleeve 9. By arranging the retaining ring 11 and the threaded shaft 12 structure, the second threaded sleeve 9 can be fixed in the sleeve 10, and a U-shaped frame 13 is fixedly connected to the outer wall of the sleeve 10, and a top frame 14 is fixedly connected to the top of the U-shaped frame 13. The bottom ends of the opposite surfaces of the top frame 14 are sleeved on the two ends of the outer wall of the armrest seat 6, and the top ends of the opposite surfaces of the top frame 14 are fixedly connected to an arc-shaped rubber sheet 15. By arranging the top frame 14, the armrest seat 6 can be fixed.

[0037] The bottom end of the outer wall of the mounting seat 1 is fixedly connected with an outer ring 16, and the top of the outer ring 16 is penetrated by a first magnetic ring 17. The outer wall of the U-shaped frame 13 is sleeved with a casing 18. By setting the casing 18, the two groups of U-shaped frames 13 can be further fixed, so that the contact positions of the two groups of U-shaped frames 13 can be made closer. At the same time, the mounting structure of the threaded shaft 12 can be shielded, which helps to improve the aesthetics of the handrail structure. The bottom of the casing 18 is penetrated by a second magnetic ring 19. The top surface of the first magnetic ring 17 is magnetically connected to the bottom surface of the second magnetic ring 19. By setting a connection structure between the first magnetic ring 17 and the second magnetic ring 19, the casing 18 can be fixed. When the cover 18 is kicked by the passenger's foot, the cover 18 may slide upward a short distance, but with the effect of the cover 18's own gravity and the suction of the first magnetic ring 17 to the second magnetic ring 19, the cover 18 can be quickly reset. At the same time, the simple connection between the first magnetic ring 17 and the second magnetic ring 19 also makes the disassembly and assembly steps of the cover 18 and the threaded shaft 12 more convenient and quick. The outer wall of the cover 18 is fixedly connected to the limit shell 20, and the outer wall of the limit shell 20 is fixedly connected to the rubber shell 21. The bottom end of the inner wall of the limit shell 20 can be covered on the outer wall of the outer ring 16, and the rubber shell 21 can protect the position where the passenger's foot kicks.

[0038] A chassis 22 is welded at the center of the top of the armrest seat 6, and the bottom ends of the outer walls of the chassis 22 are slidably connected to the concave surface of the arc-shaped rubber sheet 15. First handrails 23 are welded at both ends of the top of the chassis 22, and a first anti-slip sleeve 24 is bonded to the outer wall of the first handrail 23. A second handrail 25 is fixedly connected to the top of the first handrail 23, and a second anti-slip sleeve 26 is bonded to the outer wall of the second handrail 25. The cross-sectional size of the first handrail 23 is smaller than that of the second handrail 25. The first handrail 23 is mainly suitable for passengers with smaller hand sizes, and the second handrail 25 is mainly suitable for passengers with larger hand sizes. By arranging the first anti-slip sleeve 24 and the second anti-slip sleeve 26, it is beneficial to improve the safety of the first handrail 23 and the second handrail 25 during use.
