Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1 and 3, the lifting handrail mainly comprises a handrail 1, a sleeve 2, a square tube 3, an electric push rod 4, a mounting plate 5 and a pull rope 22.

The specific structure of the armrest 1 is shown in fig. 2, 4 and 5, and mainly comprises a first remote controller box 6, a second remote controller box 7, a first step 19, a first hole 18 and a first pin 8; a second remote controller 20 is arranged in the second remote controller box 7; a first remote controller 17 is arranged in the first remote controller box 6; the handrail 1 has a first pin 8 passing through the first hole 18 and fixed to the second hole 23.

The specific structure of the sleeve 2 is shown in fig. 1, fig. 2, fig. 3 and fig. 7, and mainly comprises a first sleeve 9, a second sleeve 10, a third sleeve 11 and a fourth sleeve 12; the first sleeve 9 is provided with a second step 24 and a second hole 23; the second sleeve 10 is provided with a third step 26 and a first snap ring 25; the third sleeve 11 is provided with a fourth step 28 and a second snap ring 27; the fourth sleeve 12 is provided with a third snap ring 29 and a third hole 30.

The specific structure of the sleeve 2 is shown in fig. 7, the first sleeve 9 is sleeved in the second sleeve 10; the second sleeve 10 is sleeved in the third sleeve 11; the third sleeve 11 is sleeved in the fourth sleeve 12; the first sleeve 9 can freely slide or rotate up and down in the second sleeve 10; the second sleeve 10 can slide or rotate freely up and down in the third sleeve 11; the third sleeve 11 can slide or rotate freely up and down in the fourth sleeve 12; the third bore 30 of the fourth sleeve 12 is secured to a fourth bore 31.

The specific structure of the square tube 3 is shown in fig. 2, 3 and 8, and mainly comprises an end cover 13, a first pulley 14, a second pin 15 and a fourth hole 31; the square tube 3 is fixed on the mounting plate 5; the end cover 13 is arranged on the square pipe 3; the first pulley 14 is arranged on the square pipe 3; the second pin 15 is mounted on the square tube 3.
