Hydraulic vehicle underframe adjusting structure

Abstract

The invention relates to the field of medical hydraulic vehicles, and discloses a hydraulic vehicle underframe adjusting structure. The hydraulic vehicle underframe adjusting structure comprises a driving device, a lifting device, an adjusting device, a braking device, a main body, a first pedal and a second pedal; the adjusting device comprises a bearing part, a first adjusting assembly and a second adjusting assembly; the first adjusting assembly and the second adjusting assembly are arranged in two containing grooves correspondingly, and the first adjusting assembly and the second adjusting assembly are both connected with the second pedal. and the lifting device comprises a first exhaust switch and a second exhaust switch. According to the hydraulic vehicle underframe adjusting structure, the height of the lifting device is changed through the adjusting device, and the descending degrees of the two ends of the bed body are different by adjusting the distance between the adjusting assembly and the exhaust switch, so that the adjustment of the bed body to inclination is realized, a traditional hand-cranking mode is changed, and the height of the bed body is adjusted through the exhaust switch, which facilitates a mechanical structure, so that the whole device is simple in structure and small in size, does not occupy too much space, and is low in overall mechanical failure rate.

Description

【Technical field】 [0001] The invention relates to the field of medical hydraulic vehicles, in particular to an adjusting structure for the underframe of the hydraulic vehicle. 【Background technique】 [0002] The hospital bed is often set up in the hospital for the rest of the patient. The bed is mainly composed of a bed body and an underframe. The existing hydraulic vehicle underframe is often equipped with a hand-operated device. By rotating the hand-operated device, the upper bed body It can be raised and lowered to meet the required height. This method is very prone to the situation that the runners are stuck, resulting in the failure of the normal lifting. This method is time-consuming and laborious, and the height of the adjustment cannot be precisely controlled. It can only be adjusted horizontally, not To realize the tilting of the bed body, the scope of application is limited, and the structure of the hand-operated hospital bed is complex, the space required is large...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the above problems and provide a hydraulic vehicle chassis adjustment structure, which solves the problems of inaccurate height adjustment of the hydraulic vehicle chassis, inability to tilt the bed body, complex structure, large volume and high production cost.
