Abstract
The utility model discloses a padlock which consists of an end closure nut and a connecting piece; wherein, one end of the connecting piece is provided with a screw thread while the other end of the connecting piece presents a hook shape; the end closure nut is connected with the screw thread end of the connecting piece. For the padlock adopting the structure, as the end closure nut is connected with the connecting piece through screw threads, a bridge body is more firmly connected with a protecting hood, which can be tightened at any time if any loosening happens, dispensing with any tools, thus being convenient in manual operation. The end closure of the end closure nut covers the end part screw thread of the connecting piece, thereby avoiding the rust of the screw thread of the connecting piece. Therefore, the padlock has a service life as long as or even is longer than that of the bridge body. Besides, the padlock is convenient in installation and elegant in appearance.
Description
Technical field
The utility model relates to a kind of shutoff device, particularly a kind of padlock that is used for fastening crane span structure main body crane span structure and guard shield.
Technical background
Crane span structure is widely used in the various installations, and crane span structure is made up of crane span structure main body and guard shield usually, and crane span structure must could link into an integrated entity the main body and the guard shield of crane span structure by padlock.At present; the padlock that uses on the crane span structure is made up of two-part; a part becomes on the hook-shaped main body that is fixed on crane span structure; another part becomes the hasp shape to be fixed on the guard shield of crane span structure; when guard shield is connected with main body; padlock fastens guard shield, guard shield fixedlyed connected with main body be integral, but the padlock of this structure; because it is unadjustable; in case the appearance when main body is connected with guard shield is loosening, then be easy to lose efficacy, use inconvenient; and padlock directly contacts with crane span structure; during installation, one is careless, just can damage the surface of crane span structure; padlock is as the annex of crane span structure; coating does not all reach the thickness of coating of crane span structure body, and under the situation of protection, the working life of padlock is not as the working life of crane span structure outside having.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of easy to use, not fragile crane span structure surface and have and surmount the crane span structure body padlock in working life.
In order to solve the problems of the technologies described above, a kind of padlock of the utility model is made up of end cap nut and link, and described link one end is provided with screw thread, and it is hook-shaped that the other end is, and described nut is connected with the link threaded one end.
Described a kind of padlock, wherein said end cap nut is made up of end cap and nut, and described end cap is provided with a regular polygon counterbore, the gabarit of described nut and described regular polygon counterbore interference fit.
Adopt the padlock of said structure, because end cap nut and link are for being threaded, can make being connected of crane span structure main body and guard shield more firm, when producing between the two when loosening, can be fastening at any time, thereby easy to use and since nut be the end cap nut, do not need to use instrument during use, manual operation is fastening to get final product, the end cap of simple to operate and end cap nut covers the end thread of link, has from then on avoided the screw thread of link to get rusty, and working life of padlock is reached or surmounts crane span structure body working life, the utility model is easy for installation, beautiful shape.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model, form by end cap nut 1 and link 3, described end cap nut 1 is connected with link 3 threaded one ends, described link 3, the one end is provided with outside thread, the other end can be J-shaped or L shaped hook-shaped, it is provided with an externally threaded end and is connected with end cap nut 1, end cap nut 1 is made up of end cap 22 and nut 23, end cap 22 is provided with a regular polygon counterbore 21, the gabarit of nut 23 and described regular polygon counterbore 21 interference fit, end cap 22 bottom surfaces have a regular polygon counterbore 21, and described counterbore 21 can be square or regular hexagon, the shape of the shape of counterbore 21 and nut 23 adapts, thereby prevent that nut 23 from rotating in described counterbore 21, nut 23 embeds in this counterbore 21, the side face interference fit in the gabarit of nut 1 and this hole 21.This end cap 22 can be the also goods of other materials of working of plastics, its shape is not limit, present embodiment adopts hemisphere, during use, be inserted into the threaded end of link 3 in the mounting hole of crane span structure guard shield 5 towards the other places from 5 li of guard shields, make the unciform end of padlock fasten the interior gib head of crane span structure main body 6, again end cap nut 1 is tightened in the threaded end of link 3 outside crane span structure guard shield 5, thereby the guard shield 5 of crane span structure is compressed crane span structure main body 6 by end cap nut 1, thereby crane span structure is connected in aggregates, adopt the padlock of said structure, because end cap nut 1 and link 3 be for being threaded, when being connected between crane span structure main body 6 and the crane span structure guard shield 5 when becoming flexible, can tighten at any time, do not need to use instrument during use, manual operation gets final product, and is convenient and reliable.
