Abstract
The utility model relates to the special nonstandard pipe nut of a kind of concrete pump connecting tube, comprise nut body, described nut body comprises cored screw and the fastening cap of internal thread, described cored screw is made up of two planes and two cambered surfaces, described hollow cylinder is equipped with chamfering in the end of corresponding fastening cap opposite direction two cambered surface, and described fastening cap is that high two sections in low centre, both sides are stepped.Adopt said structure; nut can be made not easily to rotate; and cored screw is stressed together with bolt as protecting jacket; prevent bolt from rupturing because of high vibration; the force part of nut that simultaneously fastener connects is the high two sections of stair-stepping fastening caps in low centre, both sides, can not cause damage by internal thread.
Description
Technical field
The utility model belongs to fastener areas, is specifically related to the nonstandard pipe nut that a kind of concrete pump connecting tube is special.
Background technique
Pipe nut as a kind of comparatively common fastening piece, extensive use in industrial production and daily life.Present pipe nut is all generally for cylindrical, easily follow in vibration bolt rotate together produce loosen.Particularly this high-power machinery of concrete pump, vibration is violent, easily makes the screw rod of bolt rupture when high vibration, causes concrete to overflow.
Model utility content
Problem to be solved in the utility model is to provide the special nonstandard pipe nut of a kind of concrete pump connecting tube, solves the problem of bolt screw rod fracture.
In order to solve technique scheme, the utility model adopts following technological scheme:
The nonstandard pipe nut that a kind of concrete pump connecting tube is special, comprise nut body, described nut body comprises female cored screw and fastening cap, described cored screw is that the cambered surface being equivalent to V face symmetry by two planes parallel with W face and two is formed, described hollow cylinder is equipped with chamfering in two cambered surface ends rightabout relative to fastening cap, described fastening cap is that two side portions is low, two sections of stepped formations that intermediate portion is high, in the middle of described fastening cap, high part is that the cambered surface being equivalent to V face symmetry by two planes parallel with W face and two is formed, the cambered surface of described fastening cap intermediate portion is consistent with the radian of circular fastening cap.
The utility model distance that can be set to further between described cored screw two plane is less than the distance between described fastening cap intermediate portion two plane.
The utility model beeline that can be set to further between described cored screw two cambered surface is less than the beeline between described fastening cap intermediate portion two cambered surface, and the longest distance between described fastening cap intermediate portion two cambered surface is consistent with the diameter of fastening cap.
The beneficial effects of the utility model: adopt said structure; cored screw is that two cambered surface two planes are formed; inserting the fastened thing socket corresponding with its cored screw shape; this nut not easily rotates; and cored screw is stressed together with bolt as protecting jacket, prevent bolt from rupturing because of high vibration.Fastening cap is the high two sections of stepped formations in low centre, both sides, and the force part of the nut be simultaneously connected with fastener is the high two sections of stair-stepping fastening caps in low centre, both sides, can not cause damage by internal threads.

Embodiment
The nonstandard pipe nut embodiment special to a kind of concrete pump of the utility model connecting tube referring to figs. 1 through Fig. 4 is described further.
The nonstandard pipe nut that a kind of concrete pump connecting tube is special, comprise nut body 1, described nut body 1 comprises cored screw 3 and the fastening cap 2 of internal thread, described cored screw 3 is that the plane 10 parallel with W face by two and two cambered surfaces 9 being equivalent to V face symmetry are formed, described cored screw 3 is equipped with chamfering 4 in the end of corresponding fastening cap 2 opposite direction two cambered surface 9, described fastening cap 2 is stepped by high two sections of the low intermediate portion of two side portions 56, described fastening cap intermediate portion 6 is that the plane 8 parallel with W face by two and two cambered surfaces 7 being equivalent to V face symmetry are formed, the cambered surface 7 of described fastening cap intermediate portion 6 is consistent with the radian of circular fastening cap 2.
The utility model distance that can be set to further between described cored screw 3 liang of planes 10 is less than the distance between described fastening cap intermediate portion 6 liang of planes 8.
The utility model beeline that can be set to further between described cored screw 3 liang of cambered surfaces 9 is less than the beeline between described fastening cap intermediate portion 6 liang of cambered surfaces 7, and the longest distance between described fastening cap intermediate portion 6 liang of cambered surfaces 7 is consistent with the diameter of fastening cap 2.
Described nut body 1 is being inserted the fastened thing socket relative with cored screw 3 shape of described nut, and this nut body 1 not easily rotates, and cored screw 3 is stressed together with bolt as protecting jacket, prevents bolt from rupturing because of high vibration.Described fastening cap 2 is that high two sections of the low intermediate portion of two side portions 56 are stepped, makes the force part of the nut body 1 be connected with fastener be two sections of stair-stepping fastening caps 2 that the low intermediate portion of two side portions 56 is high, can not cause damage by internal threads.
