Abstract
The utility model relates to a screwing sleeve of a round-head nut, which is a nut-screwing tool and comprises a sleeve body and an arm; the sleeve body is a cylindrical structure; the upper edge of the sleeve body is plugged with the arm and the lower edge of the sleeve body is provided with a groove which corresponds to a screw hole of a round-head bolt along the circumference. As the screwing sleeve is the cylindrical structure, and is directly sleeved outside the round-head bolt for operation, the requirements of tensioned strength of the bolt can be met no matter how large the nut and the tensioning force of the bolt are. By being used for operating, the screwing sleeve of the round-head nut has high construction efficiency and low labor intensity, saves manpower and mechanical cost and has the advantages of being economical and practical, having convenient operation and convenient carrying, and the like.
Description
Technical field
The utility model relates to a kind of nut screwing clamping instrument, specifically a kind ofly is applicable to that various cheese head screws are tightened sleeve by tight cheese head screw on the large hydraulic machine equipment.
Background technology
In the connection of large-size extruder memorial archway frame, owing to the position concerns reason or specific (special) requirements is arranged and usually adopts cheese head screw by tight bolt, usually the quilt that adopts general spanner or cheese head screw to be finished cheese head screw by spanner is tight, with these spanner operations, not only efficiency of construction is low, and can not satisfy cheese head screw by tight needs.
Along with development of science and technology, the progress in epoch, the various parts that connect with snap bolt more and more are employed, and the demand of the cheese head screw tightening tool of all size size is also constantly increased.But still be not fit to the matching tool that multiple cheese head screw is tightly used at present.
The utility model content
Goal of the invention of the present utility model is to be tightened the deficiency that intensity does not reach requirement at common wrench, cheese head screw by spanner, provides the tight cheese head screw of a kind of quilt convenient and reliable, and the cheese head screw that efficiency of construction is high is tightened sleeve.
Realize the foregoing invention purpose by the following technical solutions: a kind of cheese head screw is tightened sleeve, comprise sleeve body and arm, described sleeve body is a cylinder-like structure, be plugged with arm on the upper edge of this sleeve body, the lower edge of sleeve body is provided with and the corresponding groove of snap bolt screw hole along its circumference.
Adopt above technical scheme, compared with prior art, because the utility model is a tubular structure, directly be enclosed within the external procedure of snap bolt, no matter nut is much, and the tight power of the quilt of bolt is much, all can reach bolt by tight requirement of strength.With its job execution efficient height, labour intensity is low, saves manpower and machinery expenses.Have economical and practical, simple operation, advantage such as easy to carry.
Description of drawings
Fig. 1 is the utility model perspective view.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is user mode figure of the present utility model.
The specific embodiment
See Fig. 1, Fig. 2, a kind of cheese head screw is tightened sleeve, is made up of sleeve body 2 and arm 1, and the upper edge of sleeve body 2 has four arm openings, and four arms 2 are inserted in the arm openings successively.The lower edge of sleeve body 2 equidistantly has a plurality of little grooves 3 along its circumference, the screw hole coupling of the size of groove 3 and cheese head screw side.
That Fig. 3 provides is the embodiment that the utility model vertically uses, and at first the utility model is installed to the position of tightening of cheese head screw 5 during use, and the groove 3 on the sleeve body 2 is aimed at the screw hole of cheese head screw 5, with bearing pin they is fixed.And then install sheath 4 additional, and it is enclosed within the outside of sleeve body 2, simultaneously sheath 4 is in place, prevent that bearing pin from falling down, with hold-down nut sheath 4 to be fixed with tightening sleeve body 2 then, full wind-up 1 is tight with the cheese head screw quilt.
When cheese head screw 5 levels are used, need not install overcoat 4 additional, can directly the utility model be installed to the position of tightening of cheese head screw 5, with sleeve body 2 fixed positions, full wind-up 1 is tight with cheese head screw 5 quilts with hold-down nut.
Foregoing detailed description is to the specifying of the utility model possible embodiments, and this embodiment is not in order to limiting claim of the present utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained among the claim of this case.
