Embodiment 1

[0022] Embodiment 1: as Figure 1~5 As shown, a handrail assembly that can adjust the height up and down includes a handrail connecting seat 1, a U-shaped hoop 3, a handrail welding part 4, and an adjustment part 5; the handrail welding part 4 passes through the U-shaped hoop 3 and the adjustment part 5 is connected to the armrest connecting seat 1, the U-shaped hoop 3 is connected to the armrest connecting seat 1 through the handrail welding part 4, the adjusting part 5 is connected to the armrest connecting seat 1 through two bolts 2, and the adjusting part 5 is located at The inside of the armrest connection seat 1.

[0023] The armrest connection seat 1 includes a base 6, two side plates 7, a base plate 8 and a support plate 9, the base plate 8 and the two side plates 7 are welded on the base 6, the base plate 8 and the two side plates 7 are connected to the support The plates 9 are welded together, the two side plates 7 are provided with pin holes, the bottom of the U-sh...

Embodiment 2

[0026] Embodiment 2: The structure of this embodiment is the same as that of Embodiment 1. The difference is that the 10 pin holes on the two handrail limit plates 12 are the same size as the pin holes on the two side plates 7, and the bolts 2 are Hexagon flange bolts.

[0027] The working principle of this embodiment: when the handle 22 is pulled outward, the handle 22 drives the slider 21 to move outward along the axis II 20, and the slider 21 drives the two slider pins 16 through the connecting plate 19 to fix on the axis I15 The seat 13 moves in the direction, and the slider pin 16 escapes from the limiting holes originally inserted into the armrest limiting plate 12 and the two side plates 7. At this time, the armrest welding part 4 can be rotated to the required height on the armrest connecting seat 1. Loosen the handle 22, the slider pin 16 is under the elastic force of the return spring 17, the slider pin 16 moves to both ends of the shaft along the axis I15, and at th...

Abstract

The invention relates to a handrail assembly with vertically adjustable height, which comprises a handrail connecting base, a U-shaped hoop, a handrail welding part, and an adjusting part; the handrail welding part is connected with the handrail connecting base through the U-shaped hoop and the adjusting part, and the U-shaped hoop crosses through the handrail welding part and connects with the handrail connecting base; the adjusting part is connected with the handrail connecting base through two bolts, and located at the inner part of the handrail connecting base. According to the device, anoperator can rapidly adjust the handrail height of an agricultural machine through a control handle; thus the operator can be located in the most suitable operation height, the labor intensity is reduced, the labor production rate is greatly improved, and the market competitiveness of the product is improved. The handrail assembly is reasonable in structure design, high in general utilization, reliable in work and high in working efficiency; besides, the labor intensity can be lighted.

Description

technical field [0001] The invention relates to an armrest assembly whose height can be adjusted up and down, and belongs to the field of agricultural machinery. Background technique [0002] For the handrail assembly of traditional agricultural machinery, the height adjustment operation is cumbersome, the structure is complex, and the volume is large. It needs to be adjusted with the help of external tools, which makes it inapplicable. Cause the operator not to adjust the height of the armrest, resulting in uncomfortable operation, eventually leading to work fatigue, low work efficiency and other phenomena. Contents of the invention [0003] The purpose of the present invention is to provide a handrail assembly that can adjust the height up and down. The handrail assembly can quickly adjust the height position of the handrail of agricultural implements only through the control handle, and the height position of the handrail can be adjusted at will according to the operati...
