Reversible lock impacts pry tool
Technical field
The utility model belongs to manual rescue instrument.
Background technology
Along with the continuous progress of society, the seriousness of disasters such as natural calamity and fire, traffic accident, industrial accident is more and more by popular cognition.In order to handle the harm that disaster accident causes to people in the daily life, the rescue aid equipment that is absolutely necessary.Present most of rescue equipment is hydraulic pressure, electronic, pneumatic type, though its function is strong, active force is big, all needs running stores to replenish during operation.And the high manual rescue equipment that need not running stores of simple to operate, light, reliability is often out in the cold; yet often be trapped in the narrow space the rescue site personnel that are injured; the hydraulic pressure of large-scale many people's operations, electronic, pneumatic equipment are owing to be subjected to restrictions such as power source, tool sizes, running stores can not be deep into inside; hydraulic pressure, electronic, pneumatic equipment are because active force is big; structure around when orcible entry, can affecting, even crisis victim.A large amount of rescue experiences are told us: electronic having equipped hydraulic pressure, behind the pneumatic Large-Scale Equipment, small and exquisite, light manual rescue instrument will play irreplaceable effect near the trapped person time.
The utility model content
The utility model provides a kind of reversible lock to impact pry tool, solved the technical problem that in rescue, can manually impact and prize barrier, it can manually impact, hit and split, smash brick, member such as slabstone and armored concrete, the method that replacement rock drill, hammer knock drill rod, and than rock drill, hammering drill rod easy operating, safety.This instrument also can be used as crowbar in addition.
In order to solve the problems of the technologies described above, the technical scheme that the utility model reversible lock impact pry tool is achieved is: comprise working head, reversible lock sliding sleeve, reversible lock tool positioned steel ball, reversible lock jump bit locking ball, jump bit, overcoat and handle; Described working head is contained in described overcoat left end inside, and described working head is made up of head and shank, and the head of working head is for impacting head, cutting head or grafter capitiform formula, is provided with the groove structure that cooperates with reversible lock tool positioned steel ball at the shank of working head; Described reversible lock sliding sleeve is a cylindrical shape, and there is different hierarchic structure its inside, and the ladder jog has been put into back-moving spring; Described jump bit is made up of tup and hammer body, partly is provided with the groove structure that cooperates with described reversible lock jump bit locking ball at tup, is filled with heavy metal lead in the hollow-core construction of hammer body part.
Compared with prior art, the beneficial effects of the utility model are:
Utilize the utility model reversible lock to impact pry tool, handle moves right together with jump bit during work, returns rapidly then and impacts the working head shank, and kinetic energy is passed to working head, working head impacted object (concrete, reinforcing bar etc.) is worked so repeatedly and is finished the orcible entry operation; Also different tool heads can be goed deep into prizing in the object object and finish orcible entry.At different operations when needs are changed tool heads, the reversible lock sliding sleeve is moved right, can decontrol constraint to tool heads, lock jump bit simultaneously, after changing the good tool head, the reversible lock sliding sleeve is moved to the top of entire tool, can decontrol the constraint of the hammer that liquidates, lock tool heads simultaneously, instrument can be reworked.The mode of this quick locking can be two-way as required, also can be unidirectional.The instrument overcoat adopts high strength, lightweight alloy, and handengagabie portion processes non-skid thread.Reduce weight to greatest extent, grip reliably, be easy to carry.Handle adopts two ends projection intermediate surface processing bar-shaped trough structure.Anti-skidding, prevent it from being out of hand, grip comfortable reliable and stable.Tool heads is wide in variety, so that be fit to the manual impact under the varying environment different condition or prize barrier rescue trapped personnel.

Description of reference numerals among the figure: 1. working head, 2. reversible lock sliding sleeve, 3. reversible lock tool positioned steel ball, 4. reversible lock jump bit locking ball, 5. jump bit, 6. overcoat, 7. handle.
Specific embodiments:
It is as follows that the utility model solves the used main technical schemes of this technical problem:
In conjunction with the accompanying drawings, the impact sled axe instrument that has reversible lock mainly is made up of 7 parts: working head 1, reversible lock sliding sleeve 2, reversible lock tool positioned steel ball 3, reversible lock jump bit locking ball 4, jump bit 5, overcoat 6 and handle 7 are formed.Wherein, reversible lock sliding sleeve 2, reversible lock tool positioned steel ball 3 and reversible lock jump bit locking ball 4 are contained in the overcoat 6, jump bit 5 is contained in overcoat 6 inside, handle 7 is connected with jump bit 5, working head 1 is contained in overcoat 6 left end inside, described working head 1 is made up of head and shank, and the head of working head is for impacting head, cutting head or grafter capitiform formula, is provided with the groove structure that cooperates with reversible lock tool positioned steel ball 3 at the shank of working head 1; Described reversible lock sliding sleeve 2 is cylindrical shapes, and there is different hierarchic structure its inside, and the ladder jog has been put into back-moving spring; Described jump bit 5 is made up of tup and hammer body, partly is provided with the groove structure that cooperates with described reversible lock jump bit locking ball 4 at tup, is filled with heavy metal lead in the hollow-core construction of hammer body part.
During work, handle 7 moves right together with jump bit 5, returns the shank that impacts working head 1 then rapidly, and kinetic energy is passed to working head 1, and working head 1 impacted object (concrete, reinforcing bar etc.) is worked so repeatedly and finished the orcible entry operation; Also different tool heads can be goed deep into prizing in the object object and finish orcible entry.At different operations when needs are changed working head, reversible lock sliding sleeve 2 is moved right, can decontrol constraint to working head, lock jump bit 5 simultaneously, after changing the good berth head, reversible lock sliding sleeve 2 is moved to the left, can decontrols the constraint of the hammer 5 that liquidates, lock working head simultaneously, instrument can be reworked.
Although relate to a kind of rescue tool with reference to embodiment is disclosed, the impact, the pry tool that have reversible lock have carried out special description.Above description be illustrative be not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all changes and revising all in scope of the present utility model.
