Embodiment Construction

[0025] A combined multifunctional rescue tool described in this embodiment includes a crowbar 4, a support pad assembly and a support plate assembly.

[0026] Described crowbar 4 is made up of crowbar head and crowbar. Refer to attached Figure 8 , the root of the crowbar head is a hexagonal structure, the root of the hexagonal structure has an annular groove to form a fixed groove, and there are fixed rotating shafts protruding from both sides at the corner of the crowbar head. When in use, place the rotating shaft in the belt-shaped groove In the groove of strut 2. Refer to attached Figure 10 , the shaft part of the pry bar is a telescopic structure in the form of a sleeve combined with a limit pin, which can easily change the length of the pry bar and is convenient to use; the head of the pry bar has a head changing device, which is approximately an elliptical columnar structure, There is an axial hexagonal blind hole at the center of the end of the head changing device...

Abstract

The invention discloses a combined multifunctional rescue tool. The rescue tool comprises a crow bar, a pad component and a supporting plate component, wherein the pad component comprises a bottom plate, a supporting rod with profiled groove and a supporting rod; the supporting rod with profiled groove is connected with the supporting rod, and the supporting rod with profiled groove and the supporting rod are connected with the bottom plate at one end and on the middle part of the bottom plate respectively; the supporting plate component comprises a supporting plate base and a plurality of supports; the supporting plate base consists of two supporting substrates which are connected through a baffle plate and a bump; the pad component is arranged between the two supporting substrates; the baffle plate is sleeved on a cylindrical rod of the bottom plate and can compress a spring on the cylindrical rod together with a connecting block on the end part of the bottom plate; and the crow bar is arranged in section groove of the supporting rod with profiled groove through fixed rotating shafts on the two sides of the head. In work, a heavy object is levered up by the crow bar and supported by the supporting plate component, and the crow bar moves on the supporting rod with the profiled groove to change the height of the supporting point. One person operates the crow bar to lift the supporting point and the object can be supported while the object is levered up so the convenience of use and the rescue efficiency are greatly improved.

Description

technical field [0001] The invention relates to a rescue device, in particular to a combined multifunctional rescue tool. Background technique [0002] In the rescue sites of some disasters such as traffic accidents and house bridge collapses, the crowbar, as a purely mechanical tool, does not need external power such as hydraulic pressure or air pressure. It only needs one or several people to apply force at the same time. It is an irreplaceable advantage in the disaster scene lacking power, and the crowbar has a simple structure and is easy to carry. It is often a necessary and effective rescue tool in the disaster rescue scene. But the crowbar on the market is generally made of a single bar, and its resistance arm length is shorter, and the height that can support is limited. Often in order to increase the height of the support, the fulcrum must be raised to make it closer to the weight to be pried. In actual operation, one person applies force to pry up the heavy objec...
