Description
Technical field
The present invention relates 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 is swung, can tighten and unclamp screw or nut.It passes through past
Physical pendulum is started switching nut, convenient and efficient, laborsaving time saving, can carry out loose unloading and tight dress, strong applicability, can easily adjust
It is whole to use angle.Existing ratchet spanner using when the polygon inner hole sleeve of ratchet is mounted in the screw element that matches of geomery
On (such as screw), handle is moved in rotation, so as to fulfill the screwing operations that unscrew of screw element, when handle is moved in reverse rotation, due to
The frictional force effect in screw element thread fitting face so that ratchet, which has, stagnates power so as to overcome spring force and pawl and fixed block
Between relatively less friction, at this time, slip is produced between the gear teeth inclined-plane and pawl inclined-plane of ratchet, 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, generally all with general tool adjustable wrench or
The fork spanner that size matches, stress surface is few easily to twist de- and causes to be screwed part damage, and operator is easily injured；It is big because screwing angle
Make operating space scope big, often because packaging space of decorateing is limited the problem of and caused by work efficiency is low and economic loss.And
Existing market box socket set instrument can not be but sleeved on pipe joint screw thread part, can not solve above-mentioned elongated closed system spiral shell
Line part screws assembly and disassembly.
The content of the invention
The present invention is complicated in order to solve existing split type ratchet wrench structure, and same spanner can only correspond to applicable one
The problem of torquing operations of the threaded connector of a size, and then provide a kind of split type ratchet spanner.
The present invention is that technical solution is used by solving above-mentioned technical problem：
A kind of split type ratchet spanner, including handle, fixed core, plug, spring, pawl, one end of handle and fixed core
One end it is affixed, first through hole is offered inside the fixed core, the axis of the through hole and the axis of handle are arranged in parallel, block up
Head and spring are installed in the first through hole of fixed core successively from the bottom to top, one end of pawl and the end thereof contacts of spring, pawl
Other end be inclined-plane, it further includes split type ratchet and two groups of split type positioning 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 pawl is inserted into the teeth groove of split type ratchet, and two groups of split type positioning plates are symmetricly set on the two of split type ratchet
End, every group of split type positioning plate include two half plates being oppositely arranged, and two half plate tops being oppositely arranged are opposite to offer two
A circular groove, two circular grooves being oppositely arranged form second through hole, the wheel hub both ends point of split type ratchet
It is not installed in two the second through holes, the lower part of each half plate is affixed with fixed core by axis pin, a kind of split type ratchet wrench
Hand further includes split type inner sleeve, and the split type inner sleeve includes half set that two head and the tail are in close contact, the outside of split type inner sleeve
First polygonal through hole of profile and split type ratchet coordinates, and split type inner sleeve is fixed in the first polygon by dovetail chute
In through hole, the center of split type inner sleeve offers the second polygonal through hole along its axial direction.
Split type ratchet is positioned at the top of pawl, and the wheel hub difference of split type ratchet by two groups of split type positioning plates
Coordinate with two the second via clearances.
The lower part of each half plate is fixed at least through two axis pins with fixed core.
The present invention has the following effects that compared with prior art：
Positioning 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 line part, compared with existing monoblock type ratchet spanner, application range is wider, it is possible to increase the assembly and disassembly of mechanical equipment
Efficiency, meanwhile, overcome using easy limited to by operating space that the instruments such as common wrench and adjustable wrench occur and lead to not
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.
