Embodiment Construction

[0019] As shown in FIG. 1 and FIG. 2 , a lock screw with a built-in spring card according to an embodiment of the present invention includes a slotted bolt 8 and a clip nut 3 . Position the slotted bolt 8 on the engineering part 1 and the engineering part 2, and tighten the clip nut 3 on the slotted bolt 8 according to the end of the spring card equipped with the back to the slotted bolt 8. The thread of the slotted bolt 8 is provided with a groove 7 . The bullet nut 3 faces away from the end of the slotted bolt 8, and is provided with a bullet groove 4 and a bullet 5 contained therein, and a groove 9 connected with the bullet groove 4, and the bullet nut 3 faces away from the grooved bolt. The screw thread at one end of 8 is provided with a withdrawal groove 6.

[0020] As can be seen from the embodiment, when the spring card nut 3 is screwed with the slotted bolt 8 against the slotted bolt 8 at the end of the spring card, the exposed part of the bullet 4 in the bullet slot ...

Abstract

The invention relates to loose preventing screw with build-in spring seizing sheet. It includes groove bolt and ejecting seizing nut. The former is set at least one groove. And the latter is set at least one ejecting seizing groove. After setting the spring seizing, its part is extended into the hollow part of the nut. And its screw outlet is set flute. The ejecting seizing nut is set unloading groove. Unloading machine includes seizing ring and protecting ring. It has the advantages of safe, simple structure, convenient manufacture, and repeating use.

Description

technical field [0001] The invention belongs to the field of industrial manufacturing fasteners, in particular to an anti-loosening screw provided with a spring card. Background technique [0002] As a common fastener, bolts and nuts are widely used in various fields such as industry, agriculture, national defense, science and technology, and daily life. However, during use, nuts often loosen or slip due to external forces such as vibration, resulting in abnormal Necessary loss, and the bolts and nuts used now do not have reliable anti-loosening function usually, although some patents have also proposed anti-loosening and anti-loosening bolts or nuts (such as disclosed Chinese patents: 200320114705.3 / 200420107189.6 etc.), but Their structures are not too simple, the operation is not convenient enough, the reliability of anti-loosening is not high, or the phenomenon of nut jamming is prone to occur. Mentioned in the disclosed Chinese patent 200320114705.3, "you can first unl...
