Abstract

The invention relates to a seat stretcher vehicle, which comprises a longitudinal beam assembly and an upper wheel frame assembly. The longitudinal beam assembly has two parts, one for the left and one for the right, and includes a front joint (4) of the longitudinal beam and a rear joint (4) of the longitudinal beam ( 1), longitudinal beam tube (2), hexagon socket flat head round screw (5), hexagonal lock nut (3); the upper wheel frame assembly includes upper wheel left wheel frame assembly (10), upper wheel right wheel frame assembly ( 8), the upper wheel axle assembly (9), the upper wheel axle assembly (11), the upper wheel shaft assembly (12) and the upper wheel locking assembly (7), and the upper wheel locking assembly (7) includes a left connecting brace Plate (7.1), right connecting stay (7.10), left torsion spring (7.2), right torsion spring (7.9), backrest support (7.5) and locking mechanism tube (7.12); said left connecting stay (7.1) There are multiple gear slots (7.13) in the middle of the right connecting brace (7.10), and the gear slots (7.13) are symmetrically arranged on the left connecting brace (7.1) and the right connecting brace (7.10). Cooperate with the hexagon socket flat head round screw (5) on the lower side of the front end of the longitudinal beam assembly. The invention has good operation safety and reliability.

Description

Technical field: [0001] The invention relates to a seat stretcher vehicle, in particular to a connection structure between a longitudinal beam assembly and an upper wheel frame assembly of the seat stretcher vehicle. It is mainly used to rescue and transport patients in various environments. It is especially suitable for use in medical departments and ambulances. Background technique: [0002] Seat stretcher vehicle commonly used at present is generally made up of foot frame support assembly, hand control assembly, left longitudinal beam assembly, right longitudinal beam assembly, upper wheel frame assembly, guardrail assembly, backrest assembly and chair back assembly. The upward erection or downward flat laying action of the backrest assembly is realized by the matching belt between the longitudinal beam assembly and the upper wheel frame assembly. Since the stepless positioning is adopted between the longitudinal beam assembly and the upper wheel frame assembly, it is e...
