Abstract
The utility model discloses a guiding type screw nut. The inner surface of the cylindrical hole of the screw nut is divided into two sections. One section is a smooth inner surface, and the other is an inner screw surface. The diameter of the smooth inner surface is matched with the major diameter of the outer screw of a matched bolt. When the utility model is matched with the bolt to be installed, the screw nut and the bolt can not offset, the situation that the screw is damaged can not appear, the installation is fast, and the working efficiency is high.
Description
Technical field
The utility model belongs to the improvement of nut structure, particularly the guidance type nut.
Background technique
The nut internal thread length of using wherein is identical with the axial length of nut now, though being used, such nut and bolt can guarantee join strength comparatively reliably, but this traditional nut is when cooperating installation with bolt, nut axis and the difficult situation about overlapping of bolt axis often appear easily, dislocation causes thread damage when causing nut to turn.When this had than the bolt of fine pitch or multi-thread bolt in use, the nut inconsistent phenomenon was more obvious, needed carefully nut is aimed at bolt and made repeated attempts and repeatedly just can install inefficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of guidance type nut, can not misplace when cooperating installation with bolt, more can not occur screw thread is twisted bad situation, and is quick for installation, high working efficiency.
The purpose of this utility model is achieved in that a kind of guidance type nut, the cylindrical hole internal surface of nut is divided into two sections, one section is slippery inner surface, and another section is an interior threaded surface, and the diameter of slippery inner surface is complementary with the externally threaded big footpath of the bolt that is used.
Because the utility model nut has one section smooth internal surface, can play guiding and positioning action, when nut cooperated installation with bolt, the axis of nut was easy to overlap with the axis of bolt like this, and the situation of nut axis and bolt axial offset can not appear, prevent thread damage.The utility model nut with have when being used than the bolt of fine pitch or multi-thread bolt, install particularly fast, working efficiency is improved significantly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 looks cross-sectional view for master of the present utility model; Fig. 2 is a plan view of the present utility model.
Embodiment
A kind of guidance type nut, as shown in Figure 1, the cylindrical hole internal surface of nut 1 is divided into two sections, and one section is slippery inner surface, and another section is an interior threaded surface, and the diameter of slippery inner surface is complementary with the externally threaded big footpath of the bolt that is used.The axial length of slippery inner surface is at least 1/5 of whole nut 1 axial length.As shown in Figure 2, be positioned at and uniform on the nut side end face of slippery inner surface one side anti-skidding line 2 be set, the lines of anti-skidding line 2 should be comparatively tiny, and anti-skidding line 2 is set can be played locking and damping effect to nut 1.Because the utility model nut has one section smooth internal surface, can not only play guiding and positioning action, make the nut 1 and the axis of bolt be easy to overlap, prevent thread damage; And when being used, can also playing the effect that improves bolt fatigue strength, and can reduce vibration with bolt.The utility model nut with have when being used than the bolt of fine pitch or multi-thread bolt, install particularly fast, working efficiency is improved significantly.
Claims (3)
1, a kind of guidance type nut is characterized in that: the cylindrical hole internal surface of nut (1) is divided into two sections, and one section is slippery inner surface, and another section is an interior threaded surface, and the diameter of slippery inner surface is complementary with the externally threaded big footpath of the bolt that is used.
2, guidance type nut according to claim 1, it is characterized in that: the axial length of slippery inner surface is at least 1/5 of whole nut axial length.
