Abstract
The utility model discloses a dysmorphism screw, wherein, including bolt, nut and nut, be equipped with the screw thread on the bolt, the nut is the L type, is provided with circular arc degree no. 1, circular arc degree no. 2 on the vertical section of affiliated nut, be provided with circular arc degree no. 3 on the cross section of nut. Be equipped with gasket no. 1 and gasket no. 2 between nut and the nut. The utility model provides a dysmorphism screw transform traditional lug as L type nut, in use convenient with section bar cooperation installation, traditional lug needs follow mounting groove one end and puts into the lug when install with the section bar, and the utility model provides a dysmorphism screw can be directly puts into the nut from the upper portion of mounting groove, and through nut and the fixed connection of screw thread realization bolt with the section bar, this kind of dysmorphism screw is with to compare circular screw during the section bar is installed and use succinctly convenient.
Description
Technical field
The utility model relates to a kind of screw, particularly relates to the special-shaped screw that a kind of shape is different from standard piece.
Background technique
Section bar is as shown in Figure 1 mainly used in various load-bearing member, as can be used for the crossbeam of shelf, main and the screw of this section bar coordinates and realizes the fixing function carried, in prior art, screw is lug, as shown in Figure 2, this screw in use needs to put into lug from one end of section bar, this has many inconveniences in installation and removal, for the problem of this respect, the utility model proposes a kind of special-shaped screw.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of special-shaped screw, comprise bolt, nut and nut, described bolt is provided with screw thread, described nut is L-type, the longitudinal plane of affiliated nut is provided with circular arc degree one, circular arc degree two, the transverse section of described nut is provided with circular arc degree three, between described nut and nut, is provided with pad one and pad two.
The utility model has following beneficial effect relative to prior art:
Transform traditional lug as L-type nut, in use convenient and forced fit is installed, traditional lug is when installing with section bar, need to put into lug from mounting groove one end, and the special-shaped screw that the utility model provides directly can put into nut from the top of mounting groove, realize being fixedly connected with of bolt and section bar by nut and screw thread, this kind of special-shaped screw in installing and using with section bar compared with circular screw convenient succinct.

Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
The utility model discloses a kind of special-shaped screw, wherein, comprise bolt, nut 5 and nut, described bolt is provided with screw thread 4, described nut is L-type, the longitudinal plane of affiliated nut is provided with circular arc degree 1, circular arc degree 22, the transverse section of described nut is provided with circular arc degree 33.Pad 1 and pad 26 is provided with between described nut and nut.
Attachedly Figure 1 shows that a kind of section bar 8 of the prior art, various load-bearing member can be widely used in, as can be used as shelf bearing beam, as shown in the figure, it is fixing that the mounting groove 9 on section bar 8 coordinates screw to realize installation, and the shape of mounting groove 9 is that outside opening is little, inside opening is large, with conventional screw with the use of in, conventional screw needs just can put into mounting groove 9 in one end of section bar 8 mounting groove 9, fixes afterwards with nut 5.The different in nature bolt that the utility model provides is by the improvement to nut, directly nut can be put into mounting groove 9 in use is installed, the fixing of bolt and section bar 8 is realized by pad 3 10 pad 26, pad 1 and nut 5, in use be fixedly connected with mode convenient, it is more convenient to mount and dismount.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
