Description
Technical field
This utility model is related to a kind of spanner, and in particular to a kind of split type ratchet spanner.
Background technology
Ratchet spanner is a kind of manual screw tightening tool, when the size of screw or nut is larger or the operating position of spanner
It is very narrow, so that it may to use ratchet spanner.The angle very little that this spanner swings, can tighten and unclamp screw or nut.Which passes through past
Physical pendulum is started switching nut, convenient and swift, laborsaving to save time, and can carry out loose unloading and tight dress, and strong applicability easily can be adjusted
Whole use angle.Existing ratchet spanner using when the polygon endoporus of ratchet is sleeved on into the screw element that geomery matches
On (such as screw), handle is moved in rotation, so as to realize the screwing operations that unscrew of screw element, when handle is moved in reverse rotation, due to
The frictional force effect of screw element screw thread mating surface so that ratchet has stagnates power so as to overcome spring force and ratchet and fixed block
Between relatively less friction, now, between the gear teeth inclined-plane and ratchet inclined-plane of ratchet, produce slip, this course of work moves in circles
Realize screw element screws unscrewing operation.
Ratchet wrench mainly has conventional ratchet spanner and heavy ratchet wrench at present, but sleeve assembly is
The integrated support structure of non-fractionation, by taking the assembly and disassembly of the coupling pipe elements of heating pipeline as an example, typically all use general tool adjustable wrench or
The fork spanner that size matches, stress surface are easily twisted de- less and cause to be screwed part damage, and operator is easily injured；It is big because screwing angle
Make working place scope big, often inefficiency and economic loss are caused because decorateing the limited problem of packaging space.And
Existing market box socket set instrument but cannot be sleeved on pipe joint screw thread part, it is impossible to solve above-mentioned elongated closed system spiral shell
Stricture of vagina part screws assembly and disassembly.
Utility model content
This utility model is the rotation that closed system threaded connector cannot be realized to solve existing ratchet wrench
The problem torn open is screwed, and then provides a kind of split type ratchet spanner.
This utility model by solving the technical scheme that adopts of above-mentioned technical problem is：
A kind of split type ratchet spanner, including handle, fixed core, plug, spring, ratchet, one end of handle and fixed core
One end it is affixed, offer first through hole inside the fixed core, the axis of the through hole is arranged with the diameter parallel of handle, is blocked up
Head and spring are installed in the first through hole of fixed core from the bottom to top successively, one end of ratchet and the end thereof contacts of spring, ratchet
Other end be inclined-plane, it also includes split type ratchet and two groups of split type location-plates, and the split type ratchet includes two
By half wheel of dovetail chute head and the tail connection, and split type ratchet center offers the first polygonal through hole along its axial direction,
The other end of ratchet is inserted in the teeth groove of split type ratchet, and two groups of split type location-plates are symmetricly set on the two of split type ratchet
End, per group of split type location-plate include two half plates being oppositely arranged, and two half plate tops being oppositely arranged offer two relatively
Individual circular groove, two circular grooves being oppositely arranged form second through hole, the wheel hub two ends point of split type ratchet
It is not installed in two the second through holes, the bottom of each half plate is affixed with fixed core by bearing pin.
Split type ratchet is positioned at the top of ratchet, and the wheel hub difference of split type ratchet by two groups of split type location-plates
Coordinate with two the second via clearances.
A kind of split type ratchet spanner also includes split type inner sleeve, and the split type inner sleeve includes that two head and the tail are in close contact
Half set, the first polygonal through hole of the exterior contour of split type inner sleeve and split type ratchet coordinates, and split type inner sleeve passes through
Dovetail chute is fixed in the first polygonal through hole, and the center of split type inner sleeve offers the second polygon along its axial direction and leads to
Hole.
The bottom of each half plate is fixed with fixed core at least through two bearing pins.
This utility model is had the effect that compared with prior art：
Location-plate and ratchet are detachable, in actual application, it is possible to achieve to closed pipe-line system spiral shell
The assembly and disassembly operations of stricture of vagina part, compared with existing monoblock type ratchet spanner, range of application is wider, it is possible to increase the assembly and disassembly of plant equipment
Efficiency, meanwhile, overcome and easily led to not by working place limitation using what the instruments such as common wrench and adjustable wrench occurred
The drawbacks of use, and avoid that its stressed effect is bad and eely drawback, reduce spanner or be screwed the machine of part damage
Rate, improves the processing safety of operator.
