Abstract
The utility model relates to a special wrench for detachment of a tightening nut of a horn hole of a pipeline system. The special wrench comprises an upper fixing ring, wherein the upper fixing ring is hinged to a handle, a first half ratchet body and a second half ratchet body are tightened in the upper fixing ring, a ratchet direction adjusting shaft is arranged on the handle, a first nut adjusting block and a second nut adjusting block are fixedly arranged on the first half ratchet body and the second half ratchet body through clamping groove structures, a locking handle is arranged on the handle through a locking pin, a locking ring is arranged on the locking handle, and a pipeline nut is ensured to penetrate through the upper fixing ring, the handle, the locking pin, the locking ring and the locking handle and is locked. The special wrench has the advantage that the first nut adjusting block and the second nut adjusting block different in sizes quickly adapt to the nuts different in size, and the first half ratchet body and the second half ratchet body are combined into a complete ratchet structure, so the minimum 15-degree working requirement of a hexagon wrench is avoided, the problem of repeated direction change in the operation process is solved by the ratchet direction adjusting shaft, and the operation is more convenient and rapid.
Description
Technical field
The utility model relates to a kind of spanner, is specifically related to a kind of special spanner for the dismounting of pipe-line system bellmouth orifice clamp nut.
Background technology
At present, although develop the such Quick-disassembling tool of ratchet spanner about manufacturing enterprise,, these spanners are all form of sleeve mostly, have certain limitation when use, cannot carry out operation to the special place such as pipeline, oil piping system.Because the complexity of hydraulic pressure, pneumatic circuit system causes the withdrawal space of its maintenance and installation process bellmouth orifice clamp nut narrow and small, cannot meet the user demand of minimum 15 degree of die nut, often can pipeline around all be taken apart for certain root pipeline wherein.On the other hand, due to the diameter difference of pipeline in a system, the size of bellmouth orifice clamp nut is also different.Cause unloading process to need the spanner of different model, replacing instrument is back and forth cumbersome.So, need a kind of easy to operate, low cost, operating environment needed to the Novel ratchet spanner of special requirement, operating personnel are keeped in repair the pipeline that can not normally use in the situation that not destroying around pipeline.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of special spanner for the dismounting of pipe-line system bellmouth orifice clamp nut, simple in structure, cost is cheap, respond well to the dismounting of hydraulic pressure, pneumatic circuit PC Speaker hole clamp nut.
In order to achieve the above object, the technical scheme that the utility model is taked is:
A kind of special spanner for the dismounting of pipe-line system bellmouth orifice clamp nut, comprise retainer ring 1, upper retainer ring 1 is connected through the hinge with handle 9, the first half ratchet wheel bodies 2 are fastened in retainer ring 1 inner side concave panel, the second half ratchet wheel bodies 3 are fastened on inside handle 9 ends in concave panel, the first half ratchet wheel bodies 2 and the second half ratchet wheel bodies 3 are combined into complete ratchet, ratchet direction is adjusted axle 5 and is arranged on handle 9, the first nut adjustment block 4 and the second nut adjustment block 6 are separately fixed on the first half ratchet wheel bodies 2 and the second half ratchet wheel bodies 3 by notch, snap close handle 10 is arranged on handle 9 by snap close pin 7, snap close ring 8 is arranged on snap close handle 10.
Advantage of the present utility model:
1, simple in structure, the feature that cost is low that the utlity model has, can be used as the special ratchet spanner of dismounting of small space hydraulic pressure, pneumatic circuit PC Speaker hole clamp nut, has significant use value and prospect of the application.
2, simple to operate, the reliable feature the utlity model has, can effectively improve operating personnel's operating efficiency.
3, the utility model adopts combined type and modular design concept, provide new mentality of designing can to more Design of Mechanical Product.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structure explosive view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
See figures.1.and.2, a kind of special spanner for the dismounting of pipe-line system bellmouth orifice clamp nut, comprise retainer ring 1, upper retainer ring 1 is connected through the hinge with handle 9, the first half ratchet wheel bodies 2 are fastened in retainer ring 1 inner side concave panel, the second half ratchet wheel bodies 3 are fastened on inside handle 9 ends in concave panel, the first half ratchet wheel bodies 2 and the second half ratchet wheel bodies 3 are combined into complete ratchet, ratchet direction is adjusted axle 5 and is arranged on handle 9, realize the variation adjustment of ratchet driving direction, the first nut adjustment block 4 and the second nut adjustment block 6 are separately fixed on the first half ratchet wheel bodies 2 and the second half ratchet wheel bodies 3 by notch, the first nut adjustment block 4 and the second nut adjustment block 6 of changing different size can realize nut adjusted size, snap close handle 10 is arranged on handle 9 by snap close pin 7, snap close ring 8 is arranged on snap close handle 10, realize the locking of upper retainer ring 1.
Operation principle of the present utility model is:
Upper retainer ring 1 and handle 9 and snap close pin 7, snap close ring 8, snap close handle 10 guarantee through and locking pipe nut, by the first nut adjustment block 4 and the second nut adjustment block 6 of different size, can adapt to fast the nut of different size, thereby it is low to have cost, can overcome the shortcoming that prior art cost is high; Be combined into complete ratchet structure by the first half ratchet wheel bodies 2 and the second half ratchet wheel bodies 3, can avoid the job requirement of minimum 15 degree of die nut, when operation without pipeline around changing because working space is narrow and small; Ratchet direction is adjusted axle 5 and has been solved the problem of repeatedly changing direction in operating process, to adapt to loosen and two kinds of working methods of locking, makes faster and more convenient operation.
