Abstract
The utility model discloses a ratchet ring spanner, and relates to the field of industrial machines. The ratchet ring spanner comprises a handle and a spanner head positioned at one end of the handle, wherein the handle is rod-shaped; the spanner head consists of a racket shaft with twelve corner pores and a spanner head body; a pawl and a spring are arranged in the spanner head body; one end of the pawl is movably hinged to the spanner head body, and the other end of the pawl is connected with the spring; the handle consists of a telescopic hollow rod and a solid inner rod; four positioning bumps are formed in the hollow rod; four guide grooves are formed in the surface of the solid inner rod, and are 3.2-3.8 millimeters in depths; the racket shaft is used together with a nut sleeve. The length of the handle can be adjusted optionally, thereby saving labor to the maximum extent and bringing convenience to installation and detachment of nuts with high connecting strength. By adopting nut sleeves of multiple models, the application range is ensured. The ratchet ring spanner is simple in structure and convenient to use.
Description
Technical field
The utility model belongs to industrial machinery field, relates in particular to a kind of double offset ring spanner with ratchet.
Background technology
Spanner is a kind of conventional installation and removal instrument, utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware, along with the progressively raising of production automation level, people are also more and more higher to spanner requirement.Existing spanner, comprise wrench body and driving end, the interior axle at described wrench body two ends is with the wheel wrench head of the plum blossom structure matching with nut, in driving end, axle is also fixed with shell fragment, this decreased food is fixed, can not give full play to lever force-saving advantage, two wheel wrench head technique cost driving end models high and this invention are fixed, and working range is narrow and small.
Utility model content
For overcoming the deficiency in prior art, the purpose of this utility model is to provide a kind of double offset ring spanner with ratchet, and regulating handle length, reaches farthest laborsaving arbitrarily, is convenient to mount and dismount the nut that bonding strength is larger.
A kind of double offset ring spanner with ratchet, comprise handle and the spanner that is positioned at handle one end, described handle is shaft-like, described spanner is made up of the ratchet shaft with 12 jiaos of holes and spanner body, in described spanner body, be provided with ratchet and spring, described ratchet one end and spanner body are movably hinged, the described ratchet other end is connected with spring, described handle is made up of scalable hollow stem and solid interior bar, in described hollow stem, be provided with four road positioning convex, described solid interior bar surface is provided with four gathering sills, and described guiding groove depth is 3.2-3.8mm, and described ratchet shaft and nut sleeve support the use; Described ratchet shaft inner surface is provided with texturizing layer; Described nut sleeve one end is provided with location baffle ring.
Preferably, described texturizing layer thickness is 0.1-0.12mm.
Preferably, described hollow stem end is provided with the garment bag of meshed grooves.
The utility model has the advantage of: described handle is made up of scalable hollow stem and solid interior bar, regulating handle length arbitrarily, reach farthest laborsaving, be convenient to mount and dismount the nut that bonding strength is larger, described positioning convex and gathering sill can ensure the displacement of hollow stem on solid interior bar, can there is not sliding phenomenon, described nut sleeve model can have multiple, greatly ensure the scope of application of this utility model, described texturizing layer has improved the contact stiffness of ratchet shaft inner surface, improve service life, garment bag is more suitable for people's hand operated simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As depicted in figs. 1 and 2, the present embodiment is to provide a kind of double offset ring spanner with ratchet, it is regulating handle length arbitrarily, reach farthest laborsaving, be convenient to mount and dismount the nut that bonding strength is larger, can there is not sliding phenomenon, the spanner 2 that it comprises handle 1 and is positioned at handle 1 one end, wherein, handle 1 is shaft-like, this spanner 2 is made up of the ratchet shaft 3 with 12 jiaos of holes and spanner body 4, in the spanner body 4 of the present embodiment, be provided with ratchet 5 and spring 6, described ratchet 5 one end and spanner body 4 are movably hinged, described ratchet 5 other ends are connected with spring 6, described handle 1 is made up of scalable hollow stem 7 and solid interior bar 8, in described hollow stem 7, be provided with four road positioning convex 9, described solid interior bar 8 surfaces are provided with four gathering sills 10, described gathering sill 10 is 3.2-3.8mm deeply, described ratchet shaft 3 and nut sleeve 11 support the use, can realize the adjusting of handle 1 length, reach farthest laborsaving, can twist the nuts and bolt of Multiple Type simultaneously, can expand the scope of application, strengthen practicality.
It should be noted that described ratchet shaft 3 inner surfaces are provided with texturizing layer, texturizing layer thickness is 0.1-0.12mm.The contact stiffness that it can improve ratchet shaft 3 surfaces, increases the service life.
In addition, described hollow stem 7 ends are provided with the garment bag of meshed grooves, can increase the coefficient of friction of handle, improve operability.The present embodiment nut sleeve 11 one end are also provided with location baffle ring, avoid spanner and the direct of workpiece to contact, and can slow down the wearing and tearing of spanner.
Based on above-mentioned, described handle is made up of scalable hollow stem and solid interior bar, the length of conveniently adjusted handle, reaches farthest laborsaving, is convenient to mount and dismount the nut that bonding strength is larger, described positioning convex and gathering sill can ensure the displacement of hollow stem on solid interior bar, sliding phenomenon can not occur, and described ratchet shaft and nut sleeve support the use, and make spanner can twist nut, the bolt of various models, expand the scope of application of spanner, can reduce spanner production cost simultaneously.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
