A kind of multifunctional manual dilator

Abstract

The invention discloses a multifunctional manual expander, which comprises a bearing seat, a crawling seat, a connecting rod, a step-up pull plate, a step-up rocker seat, a climbing plate, an auxiliary sleeve and a locking piece, and the crawling seat and the load-bearing seat are respectively covered with On the climbing plate, a number of climbing holes are arranged on the climbing plate, bearing platforms and hinged seats are respectively arranged on both sides of the bearing seat, connecting rods are hingedly installed on the hinged seats, and auxiliary sleeves are installed on the climbing holes to assist The sleeve includes a sliding sleeve on which a pressing table is fixed, and a matching plate is arranged on the upper part of the pressing table, a number of sliding sleeve pin holes are arranged on the sliding sleeve, a fixing groove is arranged on the sliding sleeve, and a fitting plate is arranged on the matching plate. Cooperate with the round hole and the polygonal hole, the bottom plate is provided with a fixed sleeve, a number of reinforcing plates are provided around the fixed sleeve, a support rod is provided between the reinforcing plates, and a rotating sleeve is provided in the fixed sleeve. cylinder. The invention has the advantages of simple structure, light weight, convenient transportation and carrying, high working efficiency, large load-bearing quality and easy maintenance.

Description

【Technical field】 [0001] The invention relates to the technical field of dilator equipment, in particular to the technical field of a multifunctional manual dilator. 【Background technique】 [0002] The expander is a rescue tool, mainly used in the field of firefighting. It can spread heavy objects and rescue people trapped below. At present, full hydraulic pressure is used as the power source for firefighting. This kind of equipment requires high precision parts and low failure rate. High, inconvenient maintenance, complex structure, heavy weight, inconvenient transportation and slow speed, can not meet the needs of fire rescue. At present, some companies have developed screw-type expanders, although the quality It is lighter, but the load-bearing capacity is small and the speed is slow, which still cannot meet the needs. The market needs an expansion device with light weight, large load-bearing capacity, simple structure, and convenient maintenance. At the same time, the e...
