Abstract
A mechanical gap expander is composed of telescopic pliers, a shell body, a fixing pin, a fixing block, bolts, short connecting rods, long connecting rods, a threaded rod, a moving block, a supporting block, bearings and the like. The telescopic pliers are fixed on the shell body through the fixing pin. The fixing block and the supporting block are fixed on the shell body through the bolts. One short connecting rod is screwed into the telescopic pliers and hinged with one long connecting rod. The long connecting rod is hinged with another short connecting rod which is screwed into the supporting block. The threaded rod simultaneously penetrates through the fixing block, two bearings, the moving block and the supporting block. The bearings are inlaid in the fixing block and the supporting block at the same time. A matched ratchet wrench is used to be sleeved at the outer end of a hexagon of the threaded rod, or a motor is used to drive the threaded rod so that the threaded rod can be driven in forward and reverse directions conveniently. The mechanical gap expander is mainly used for rescuing endangered people buried in ruins, expands rescuing space in time, saves time, and meanwhile greatly reduces physical output of rescuers.
Description
Technical field:
The utility model relates to a kind of rescue, escaping tool, specifically a kind of mechanical type crack extension device.
Background technology:
In recent years, because that various disasters cause distress personnel to be extruded into the event of small space is increasing, it is a rescue work that extremely consumes one's strength and need to race against time that distress personnel is rescued from small space.When the slit very little, when the rescue personnel can't directly sue and labour, traditional rescue mode is the direct free-hand expansion rescue of rescue personnel space, but this rescue mode consumes a large amount of muscle power of rescue personnel, length consuming time, operation inconvenience, and in the rescue process, cause easily rescue personnel and distress personnel repeatedly injured.This mechanical type crack extension device is simple in structure, and is easy to operate, safe and reliable; Can save rescue personnel's muscle power, shorten the time of suing and labouring, to get the rescue time of more preciousnesses.
Summary of the invention:
The purpose of this utility model provides a kind of mechanical type crack extension device, and it can in time rescue distress personnel and shorten the time of suing and labouring when distress personnel be extruded into small space, makes distress personnel overcome fear, steadily rescues disaster-stricken environment with safety.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of mechanical type crack extension device, by extension tongs, housing, steady pin, fixed block, bolt, short connecting rod, long connecting rod, threaded rod, movable block, back-up block and bearing form, extension tongs is fixed on the housing by steady pin, fixed block and back-up block are bolted on housing, short connecting rod screws in extension tongs, and and long connecting rod is hinged, long connecting rod is hinged with another short connecting rod again, another short connecting rod screws on the back-up block, threaded rod passes fixed block simultaneously, two bearings, movable block and back-up block, bearing is embedded on fixed block and the back-up block simultaneously, and the motor that threaded rod stretches out shell ends and ratchet spanner or driving threaded rod is connected.
One end of described upper extension tongs and lower extension tongs all is tabular, and connection nested against one another.
One end of described threaded rod is circular, bar section intermediate surface is screw-like, the other end is regular hexagon, circular threaded rod one end inserts fixed block, whole threaded rod screws in and passes movable block, and being fixedly connected with threaded rod with the bearing that is nested in the back-up block, the device cover that threaded rod one end of regular hexagon and ratchet spanner etc. drive threaded rod connects.
Described fixed block and movable block inside all are provided with draw-in groove, and fixed block is connected draw-in groove and all is connected with bearing with movable block.
The operation principle of described mechanical type crack extension device is: by screw-nut body the threaded rod rotation torque is become linear thrust and pass to toggle, toggle drives the extension tongs that is positioned at front end again, the principle of opening by extension tongs enlarges fast to narrow and small slit, strives for time enough and space to next step rescue.
Outstanding advantages of the present utility model is:
Use the screw-nut body carry-over moment, realized auto-lock function, when guaranteeing safety, effectively saved the energy; The utility model device dexterously with extension tongs as a toggle part, and avoided the toggle dead-centre position during structural design; Because the extension tongs cross section is larger, can bear larger load; This installs available ready-made square-tube type steel and makes shell, saves cost.

The specific embodiment:
Below in conjunction with drawings and Examples this utility unit is further described.
The concrete structure of mechanical type crack extension device described in the utility model is:
This practical operation principle is: when the rescue personnel rescues, threaded rod stretches out hexagon one end and corresponding ratchet spanner socket (or using the motor-driven threaded rod) of housing, apply moment of torsion with ratchet spanner and make threaded rod 13 rotations, threaded rod 13 by and movable block 12 between the screw pair structure movable block 12 is moved forward, movable block 12 moves forward and passes torque to the first short connecting rod 3, the first long connecting rod 7, mechanism and the 3rd short connecting rod 18 that the second short connecting rod 11 forms, the second long connecting rod 22, the mechanism that the 4th short connecting rod 25 forms, two mechanisms are passed to upper extension tongs 1 and lower extension tongs 17 to moment again, upper extension tongs 1 and lower extension tongs 17 Rapid Expansion under the effect of power.
After reaching required height, because the existence of the mechanism that the mechanism that the first short connecting rod 3, the first long connecting rod 7, the second short connecting rod 11 form and the 3rd short connecting rod 18, the second long connecting rod 22, the 4th short connecting rod 25 form, overall structure forms self-locking, and movable block 12 can not move backward; So that do not continuing to provide in the situation of kinetic moment, upper extension tongs 1 and lower extension tongs 17 can not shrink because of the Action of Gravity Field of weight, and can continue to maintain required height.
When wanting the shrinkage expansion device, only need with ratchet spanner or drive motors turn-back threaded rod 13, it is mobile backward that threaded rod 13 reverse rotations drive movable block 12, movable block 12 passes to the mechanism of the first short connecting rod 3, the first long connecting rod 7, the second short connecting rod 11 compositions and the mechanism that the 3rd short connecting rod 18, the second long connecting rod 22, the 4th short connecting rod 25 form with opposing torque, and two mechanisms shrink extension tongs 1 and lower extension tongs 17 under the effect of power.
