Abstract
提供一种螺母，其外轮廓为等边五角形(21)。同时提供一种用来旋紧或松卸上述的螺母的专用扳手，扳手具有内等边五角形(32)。上述螺母必须通过本上述的扳手进行打开，可以有效地防止螺母被轻易松开，达到防盗的功能。
A nut is provided, the outer contour of which is an equilateral pentagon (21). At the same time, a special wrench for tightening or loosening the above-mentioned nuts is provided, and the wrench has an inner equilateral pentagon (32). The above-mentioned nut must be opened by the above-mentioned wrench, which can effectively prevent the nut from being loosened easily and achieve the anti-theft function.
Description
Technical field
The utility model relates to a kind of new type nut, belongs to the fastening piece that connects usefulness between machinery zero (portion) part.The utility model also relate to screw/pine unload the operation above-mentioned new type nut special spanner.
Background technique
At present, in machining, nut commonly used is used with screw and carries out fastening connection.Though nut internal diameter different sizes, its mechanism and profile are all as shown in Figure 1, comprise that interior threaded hole 2, external frame are equilateral hexagon 1.
Just because of equilateral hexagon is a symmetric shape, promptly always there is one group of limit parallel each other.Still be that spanner wrench can both screw it or pine is unloaded no matter with back-up wrench.Therefore, the installation and removal of six-sided nut are very convenient.
Yet in some engineering field, as: the electric power equipment box in the industries such as harbour machinery, mining machinery, large-scale electromechanics, shipbuilding, electric power facility, bridge, high frame iron tower; Pressurized container in the chemical machinery and sealed boiler; In municipal communal facility, the inspection shaft of road administration facility lid, cable machinery cabinet etc., nut does not wish to be opened by pine after fastening, otherwise will produce potential safety hazard, makes troubles for the people's live and work.
In addition, when the material that is adopted when fastened zero (portion) part and accessory thereof had the electric wire, cable, copper material, alloyed steel of higher economic value etc., in case the nut pine is opened, above-mentioned material was stolen easily, brings heavy economic losses for country and manufacturing enterprise.
The model utility content
The utility model is to address the above problem, and a kind of nut that can not be opened easily is provided, and can use in above each engineering field, and the equipment that effectively prevents is stolen, be not damaged.
In order to reach described purpose, the utility model provides following technological scheme.
A kind of nut is characterized in that: its external frame is equilateral pentagon.
Owing to all have angle between equilateral pentagonal any both sides, and do not have parallel opposite side, therefore can not operate, not only effectively clamping but also can not supportingly use by spanner wrench or back-up wrench.Each loading and unloading all must be used special use and pull tool, can avoid the nut after fastening to be dismantled privately effectively.In addition, in actual use, need not to change operating habit, easy and simple to handle.Can satisfy different pretightening force needs.
Nut profile of the present utility model is equilateral pentagon, and manufacturability is strong, helps manufacturing.
Nut of the present utility model more is applicable to larger-diameter nut, is generally greater than M12 and above specification thereof.According to different occasions and demand, be made in the different-diameter specification, be widely used in, as: the electric power equipment box in the industries such as harbour machinery, mining machinery, large-scale electromechanics, shipbuilding, electric power facility, bridge, high frame iron tower, pressurized container in the chemical machinery and sealed boiler, and in municipal communal facility, the inspection shaft of road administration facility lid is fixing, cable machinery cabinet etc., nut does not wish to be opened by pine after fastening, can prevent effectively that equipment is stolen, not be damaged.
The utility model nut is compared with existing nut, has only changed profile, does not change internal structure, and is consistent with existing nut using effect therefore in actual use, can satisfy with the screwing of other machinery zero (portion) part/pine and unload operation.
For screw/pine unloads above-mentioned nut of the present utility model, the utility model also provides a kind of specialist tools.
A kind ofly be used for screwing or pine is unloaded the special spanner of the utility model nut, it is characterized in that: spanner has equilateral pentagonal endoporus.
Spanner of the present utility model is stuck in interior equilateral pentagonal hole on the nut of the present utility model, carries out the different direction rotation, can realize screwing with pine of the utility model nut unloaded.Certainly, for the nut of the present utility model of different size, also will dispose the special spanner of different size, its matching relationship is with the cooperation of existing nut and back-up wrench.
Therefore, the utility model nut must be opened by spanner of the present utility model, can prevent effectively that nut from being unclamped easily, reaches antitheft function.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is existing nut structure schematic representation.
Fig. 2 is a nut plan view of the present utility model.
Fig. 3 is the A-A sectional view of nut shown in Figure 2.
Fig. 4 be used to screw/pine unloads the special spanner of nut of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Fig. 2, shown in Figure 3, the present embodiment nut is identical with existing nut, has interior threaded hole 2, but its external frame is equilateral pentagon 21.
Owing to all have angle between any both sides of equilateral pentagon 21, and do not have parallel opposite side, therefore can not operate, not only effectively clamping but also can not supportingly use by spanner wrench or back-up wrench.Each loading and unloading all must be used special use and pull tool, can avoid the nut after fastening to be dismantled privately effectively.In addition, in actual use, need not to change operating habit, easy and simple to handle.Can satisfy different pretightening force needs.
Present embodiment nut profile is equilateral pentagon 21, and manufacturability is strong, helps manufacturing.
The present embodiment nut has than major diameter, greater than M12.The present embodiment nut is compared with existing nut, has only changed profile, does not change internal structure, and is consistent with existing nut using effect therefore in actual use, can satisfy with the screwing of other machinery zero (portion) part/pine and unload operation.
For screw/pine unloads above-mentioned present embodiment nut, a kind of embodiment of special spanner is as shown in Figure 4.This spanner has the endoporus of equilateral pentagon 32, and external frame is rounded.
The spanner of present embodiment is stuck in the hole of interior equilateral pentagon 32 on the external frame of equilateral pentagon 21 of nut of present embodiment, carries out the different direction rotation, can realize screwing with pine of present embodiment nut unloaded.Present embodiment nut and present embodiment special spanner, its matching relationship is with the cooperation of existing nut and back-up wrench.
The nut of present embodiment must be opened by the spanner of present embodiment, can prevent effectively that nut from being unclamped easily, reaches antitheft function.
More than be one of mode of execution of the present utility model,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize the purpose of this utility model equally for those skilled in the art.But this variation obviously should be in the protection domain of claims of the present utility model.
Claims (3)
1, a kind of nut is characterized in that: its external frame is equilateral pentagon (21).
2, a kind ofly be used for screwing and pine is unloaded the special spanner of operation nut as claimed in claim 1, it is characterized in that: spanner has the endoporus of equilateral pentagon (32).
3, nut as claimed in claim 1 is characterized in that: the diameter of described nut is greater than M12.
