Description

A kind of anti-skidding housing spanner

Technical field

The present invention relates to a kind of spanner, more particularly to a kind of housing spanner for having anti-skidding effect belongs to industrial technical field.

Background technology

Screw (outer literary fame：Screw), it is former using the inclined-plane circular rotating of object and the physics and mathematics of frictional force Reason fastens the tool of implements parts by easy stages.Screw is the general saying of fastener, daily pet phrase.Screw is daily Indispensable industrial necessity in life：The minimum screw that such as camera, glasses, clock and watch, electronics use；TV, electricity The general screw of gas product, musical instrument, furniture etc.；As for engineering, building, bridge then using large-scale screw, nut；Traffic tool, Aircraft, electric car, automobile etc. are then used in combination for big primary screw.Screw industrially bears vital task, as long as there is works on the earth Industry, then the function of screw is forever important.Screw is the joint invention in people's production and living over the past thousands of years, is come according to application field It sees, it is the first major invention of the mankind.

With the invention of screw, spanner has also correspondingly been invented out.Spanner is a kind of common installation and extracting tool. The craft that bolt, screw, nut and other screw threads tightly hold the opening or trepanning firmware of bolt or nut is twisted using lever principle Tool.Spanner, which is usually formed with clamp holder portion in the one or both ends of shank and applies external force shank, applies external force, with regard to can twist bolt or Nut holds the opening or sets of holes of bolt or nut.Threadingly direction of rotation applies external force in shank during use, with regard to that can twist bolt Or nut.Spanner usually uses carbon structural steels or alloy structure steel making.

Spanner is divided into two kinds substantially, solid wrench and adjustable wrench.The former refers to the spanner that fixed number is write, The latter is exactly monkey wrench.

1. fork spanner：One or both ends are formed with fixed-size opening, to twist the nut of certain size or bolt.

2. double offset ring spanner:Both ends have the working end with hexagon ring or 12 corner apertures, narrow suitable for working space, it is impossible to Use the occasion of common wrench.

3. combination wrenches：One end is identical with single head fork spanner, and the other end is identical with double offset ring spanner, and same size is twisted at both ends Bolt or nut.

4. adjustable wrench：Opening width can be adjusted in the range of certain size, can twist the bolt or spiral shell of different size It is female.The spanner to be structurally characterized in that the flat pliers with serration is made in regular jaw recessed；Flat pliers mouth is made in moving jaw one end；It is another The recessed jaw with serration is made in end；Worm screw is pressed downwards, moving jaw can be removed rapidly, exchange jaw position.

5. hook spanner：Also known as crescent wrenches, for twisting restricted jam nut of thickness etc..

6. box spanner：Commonly referred to as sleeve:It is by multiple sleeves with hexagon ring or 12 corner apertures and equipped with handle, The multiple accessories such as extension bar form, especially suitable for twist status it is very narrow or recess very deep bolt or nut.Sleeve has Point of metric system and English system, although sleeve concave shape is the same, outer diameter, length etc. are set for the shape and size for corresponding to equipment Meter, country, so the design of sleeve is comparatively relatively more flexible, meets public needs without Uniform provisions.Box spanner The use such as collet head and handle of waving, extension bar, universal joint, driver connector, elbow handle generally all with a set of various specifications To be inserted in hexagonal (hexagon)nut.The collet head of box spanner is a recessed hexagonal cylinder；Spanner is usually by carbon structural steels or conjunction Golden structural steel is made, and Wrench head has defined hardness, and intermediate and handle portion then has elasticity.

7. allen wrench：The rodlike spanner of L-shaped hexagonal, is exclusively used in twisting soket head cap screw.The type of allen wrench Number it is for the opposite side size according to six sides, the size of bolt has national standard.Purposes：Specialize in fastening or dismounting lathe, vehicle , the round nut on mechanical equipment uses.

8. torque spanner：It can show applied torque when twisting bolt or nut；Or when the torque applied After reaching specified value, light or audible signal can be sent out.Torque spanner be suitable for have to torque it is manifestly intended that assembling.

Manual wrench is called common wrench, is mainly used in common life and work, its use is fairly simple, main point For single head fork spanner, double ended spanner, adjustable wrench, double offset ring spanner, combination wrench, tap spanner, box spanner, sleeve driver, Torque spanner, torque wrench, cross like spanner, ratchet spanner, hook spanner, allen wrench, interior four square head wrench, manual clutch formula Torque wrench, bulldog wrench, T-shaped spanner, L-type spanner, trident spanner, knuckle buster, oil drum spanner, tyre wrench, spark plug Spanner, wrench for filter, combination wrench, other spanners etc..Torque wrench is divided into information ring spanner, pointer spanner, digital display spanner.

The shape that common wrench is provided to cater to screw terminal is inserted in shape or is inserted in interior shape, by rotate and Obstruction is generated, so as to which screw be driven to rotate, screw is rotated, screw is able to screw or loosen.But all wrench are all Shape in screw head surface is in close contact or cannot prevent unexpectedly to occur as possible, when screw tension or when getting rusty or Some screw quality are too poor and scratched corner by spanner, produce sliding situation about pulling, and at this moment spanner just dallies, and does not work .Present some screws manufacturer slacks off decrement, makes screw using steel inferior, screw angle is easy to be turned round by spanner and scrapes and collapse Angle, then increased force are turned round several times, and screw angle is just collapsed circular, and screw is motionless.When the spanner for using all instead all cannot When solution, can only related component be subjected to cutting damage.

Invention content

In order to cope with decrement of slacking off to present some screws manufacturer, screw is made using steel inferior, screw angle is easy to It is scraped and angle of collapsing by spanner torsion, sliding situation about pulling.Thus we have invented a kind of anti-skidding housing spanner of new product, this new spanner is special Door tackles those screws for having slided spanner, very quickly, triumph screws out screw.

A kind of anti-skidding housing spanner solves the problems, such as to be adopted the technical scheme that：A kind of anti-skidding housing spanner includes annular sleeve Body, annular sleeve import, handle, blade composition；The handle links into an integrated entity with annular body；Shape in the annular sleeve body Hollow is annular running-on, and annular running-on is by regular, continuous concave right angle, obtuse angle or the continuous raised acute angle of rule, the convex company in mound It connects and surrounds；The annular body can also be unconnected semi-circular；Blade is installed in side in the annular sleeve body；It is described Lancet base be set in the positions of lateral projections in annular sleeve body, the edge of a knife stretches out, and the edge of a knife is directed toward the center of circle of annular body, knife Plate plane is parallel with the direction line that spanner packs into.

A kind of anti-skidding housing spanner, the edge of a knife of the blade are ramp-like in one end that spanner annular running-on packs into, and are conducive to Blade stress promotes, and gradually cuts insertion cap nut, cap nut, which is tightly bitten, to be slided.

Specific embodiment

The explanation that can be made further is implemented to a kind of anti-skidding housing spanner work below in conjunction with the accompanying drawings.

Fig. 1 Fig. 1 is a kind of Facad structure schematic diagram of the anti-skidding housing spanner of hexagon.The anti-skidding housing of hexagon in figure is pulled The annular body 2 of hand and 1 connecting integration of handle, handle 1 extend a segment length, the torque pulled conducive to acquirement.Ring in figure 2 internal void of shape body, which is divided into, packs into mouth 3, and set import 3 is made of six identical faces and six identical angles, in fact, this The common hexagon housing spanner seen with us is essentially identical, and this spanner can just be packed into outside hexagon cap nut, Carry out torsion screw.But one piece of blade 4 is stretched out among each face in the six of this spanner faces, this block blade 4 is put down The face two faces handing-over line adjacent with 2 medial surface of annular body is parallel.In Fig. 1, it is seen that, 4, this block blade stretches out one Segment, exactly this is a bit of, and spanner will be hindered to pack into cap nut, this illustrate this spanner be not suitable for packing into it is common hard Hexagon cap nut, even if still cannot directly be packed by the cap nut at torsion slumping angle.Generally by the torsion slumping spiral shell at angle Silk cap, be all because caused by the metal that uses of its cap nut is not hard enough as a result, this shortcoming just by us this one The anti-skidding housing spanner of kind is utilized, because the blade 4 in our this spanner set imports 3 is harder than this cap nut, if I Hit to a kind of anti-skidding one hitting power packed into of housing spanner, such as with bell, blade 4 will pushing away with set import 3 And then the inside of cap nut is injected, and when handle 1 carries out laterally turning to twist, blade 4 will hinder the rotation of annular body 2, this Kind hinders finally to screw out screw to rotate together with screw.

A kind of blade installation of anti-skidding housing spanner can be suitble to all housing spanners, that is to say, that all housings are pulled Hand can add the anti-skidding blade of insert as a kind of anti-skidding housing spanner, below our quincunx Anti-shift spanners make example.Fig. 2 is A kind of Facad structure schematic diagram of quincunx anti-skidding housing spanner.Quincunx housing spanner is to turn round the more spiral shell in some angles for covering Silk cap, still, when some second-rate polygonal cap nuts, which are turned round, has collapsed angle, at this moment cap nut almost becomes round.This When changes us this quincunx anti-skidding housing spanner, will give full play to one's remarkable skill, we will cover import alignment cap nut, with bell to set Annular body 2 is hit into direction, blade 4 will be injected inside cap nut, and with the continuation of the number of strike, annular body 2 is complete Screw cap sleeve is bitten, at this moment twists handle, screw is screwed out.

In order to more clearly express a kind of installation situation of anti-skidding housing spanner blade, we show Fig. 3.Fig. 3 is one The side sectional median plane figure of the anti-skidding housing spanner of kind.Blade 4 in figure welds or is installed in the medial surface of annular body 2, the edge of a knife It is stretched out to the center of annular body.The plane of blade 4 is parallel with the direction that set import 3 packs into, conducive to propulsion.Blade 4 exists in figure The one end for covering import 3 is ramp-like for knife, in this way, the blade 4 around set import 3 will collectively constitute a horn mouth, is conducive to pack into Mouth 3 can be induced direction, gradually tightly sting and pack into.In fact, the blade 4 described in us only stretches out a bit, generally only 1~3 milli Rice, and the edge of a knife is sharp, and substrate is thick big, is conducive to firmly to inject metal inside and is difficult to be broken off.If the mistake that blade 4 is stretched Height may be broken by kinking, and the difficulty for injecting metal increases, and certainly, this will be installed or weld according to the size of spanner Connect the blade 4 of different size thickness.
