The squared profile structure that described perpendicular support, middle horizontal support, the location horizontal support of upside, the location horizontal support of downside use cross section to be four T-shaped groove shapes, described location horizontal support is connected by right angle section jointing part with the perpendicular both sides up and down supported, the position of described fixing hole coordinates with the connecting hole position of right angle section jointing part, and perpendicular support is connected with middle horizontal support, the location horizontal support of upside, the location horizontal support of downside by right angle section jointing part, SOC.HD. cap screw.
Top in same adapter sleeve is erected the lower surface of support and is erected the upper surface of support with bottom and contact.
Being provided with bottom support plate bottom the perpendicular support of foot, be provided with the slipmat of the increase such as rubber or plastics and frictional ground force in the bottom of bottom support plate, bottom support plate uses detachable connection with the perpendicular support of foot.
Beneficial effects of the present invention:
1. present configuration is simple, easy accessibility, the space such as can be advantageously placed in car back in-support carriage after dismounting, being easy to load and transport, required constitutional detail versatility is good, and processing is simple, assembling efficient and convenient, cost of manufacture is low, and the convenient occasion being inconvenient to field etc. carry and assemble uses.
Top in the most same adapter sleeve is erected the lower surface of support and is erected the upper surface of support with bottom and contact, the quality of upper ladder part directly transmits the ladder portion being applied to bottom, alleviate the active force that inserted joint casing composite module is subject to, increase the security reliability of complete machine.
3. the inserted joint casing composite module of the present invention, squared profile structure and right angle section jointing part are of many uses, the ladder structure of the present invention can use directly as emergency stretcher after spreading soft mat, then can also use as desk or stool at supporting leg desktop installed above as supporting leg, it is also possible to be additionally arranged at the bottom wheel at desk and use as moveable dolly or container.
