Description

Handrail base of passenger room upright post

Technical Field

The utility model belongs to the mechanical equipment field, in particular to guest room stand handrail base.

Background

The passenger room upright posts are important components installed in the urban rail train, are uniformly distributed along the longitudinal center line of the train, are usually positioned between the train doors at two sides, provide vertical supporting force for a train body and other armrest upright posts, and can also directly serve as an armrest. The upright post handrail base provides supporting and fixing functions, and in order to ensure that the upright post is firmly installed, the fastening screws must be long enough to penetrate through the floor steel structure and the supporting cross beam. In the processes of manufacturing, overhauling, disassembling and assembling a new vehicle, the long bolt is difficult to disassemble and assemble due to the limitation of the installation space; in the long-term operation of vehicle, the floor cloth makes the moisture around the stand too big because of often making the cleanness, leads to the stand base corrosion serious.

Disclosure of Invention

In order to solve the problem, the utility model provides a guest room stand handrail base mainly solves the problem of stand dismouting difficulty and solves the problem of sealed bad easy corrosion.

The utility model adopts the technical proposal that: the utility model provides a guest room stand handrail base, height adjustment seat support and adjustment stand, and is fixed through lock nut between height adjustment seat and the stand, and the periphery is covered with the cup cover, the lower part threaded connection of cup cover and height adjustment seat, the cup cover passes through the sealing washer with the stand and seals, and height adjustment seat passes through fixing bolt from last to being connected with floor cloth, aluminium honeycomb floor, stainless steel floor, chassis crossbeam down in proper order, and there is sealing member in the gap between cup cover and the floor cloth.

Further optimizing, the length of the fixing bolt does not exceed the distance between the upper surface of the base of the height adjusting seat and the lower plane of the upright post, and the fixing bolt penetrates through the cross beam of the underframe after fastening.

Further optimizing, the outer diameter of the locking nut does not exceed the outer diameter of the upright post, and a spring washer is arranged between the locking nut and the upright post.

Further optimize, imbed the sealing washer between cup cover and the stand, sealing washer quantity is one or two.

And further optimizing, and coating a sealant on the periphery of the gap between the cup cover and the floor cloth.

The utility model has the advantages that:

1. the fixing and height adjustment between the upright post and the floor are realized through the height adjusting seat;

2. the problem of interference between the fixing bolt and the locking nut during installation is solved through the locking nut;

3. the problem that the locking nut is easy to loosen is solved through the spring washer;

4. the problem of corrosion caused by poor sealing inside the cup cover is solved through sealing components such as the sealing ring and the sealant.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, the utility model discloses a guest room stand handrail base comprises stand 3, cup cover 2, floor cloth 7 etc. and adopts sealing member to seal between cup cover 2, the floor cloth 7 for increase bottom connection leakproofness, the sealed mode in fig. 1 is that sealed glue 11 is scribbled in the gap between cup cover 2 and floor cloth 7, can also install seal gasket etc. additional between cover 2 and floor cloth 7.

As shown in fig. 2, the height adjusting base 1 supports and adjusts the upright post 3, the height adjusting base 1 and the upright post 3 are fixed by a lock nut 5, the periphery is covered with the cup cover 2, and the cup cover 2 is in threaded connection with the lower part of the height adjusting base 1.

As shown in figure 2, two sealing rings 4 are arranged at the upper end inside the cup cover 2, so that the sealing performance between the upper part of the cup cover 2 and the upright post 3 is improved. The height adjusting seat 1 is connected with the floor cloth 7, the aluminum honeycomb floor 8, the stainless steel floor 9 and the underframe cross beam 10 through four fixing bolts 6 from top to bottom in sequence, the four fixing bolts 6 are uniformly distributed along the circumferential direction, the stand column 3 is effectively fixed, and the stand column 3 is more stable during use. The length of the fixing bolt 6 does not exceed the distance between the upper surface of the base of the height adjusting seat 1 and the lower plane of the upright post 3, and the fixing bolt 6 penetrates through the underframe cross beam 10 after being fastened.

As shown in figure 2, the height adjusting seat 1 is connected with the upright post 3 by adopting a lock nut 5, and a spring washer 12 is arranged between the lock nut 5 and the upright post 3 to prevent the lock nut 5 from loosening caused by the vibration of the vehicle body when in use. The outer diameter of the locking nut 5 is not more than that of the upright post 3, the structure is convenient for the disassembly and the assembly of the fixing bolt 6, and the fastening effect of the locking nut 5 is better.

When the height adjusting seat is installed, the height adjusting seat 1 and the bottom surface of a vehicle body are fixed through the fixing bolt 6, then the locking nut 5 is screwed into the nut at the upper end of the height adjusting seat 1, then the spring washer 12 is padded on the locking nut 5, then the upright post 3 is screwed into the nut at the upper end of the height adjusting seat 1 to a proper height, then the locking nut 5 is rotated, and the upright post 3 is fixed to the position through the locking nut 5. And finally, sleeving the cup cover 2 from the upright post 3, rotating the cup cover 2 to fasten the cup cover with the lower part of the height adjusting seat 1 through threads, and then punching a circle of sealant 11 at the gap between the cup cover 2 and the floor cloth 7. If the height needs to be adjusted, only the locking nut 5 needs to be rotated to enable the locking nut 5 to leave the lower plane of the upright post 3, then the locking nut 5 is rotated after the height is adjusted, and the upright post 3 is fixed at the position through the locking nut 5.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
