Abstract
The utility model discloses a V-shaped clamp-spring self-locking screw nut which is designed according to the principle of friction locking and the elastic characteristic of the spring and comprises the screw nut and a clamp-spring. A positioning groove is arranged inside the screw nut. The tail end of the clamp-spring arranged inside the positioning groove is fixed to a fixing hole. The clamp-spring is made of V-shaped spring steel. The screw nut is also provided with a disassembly hole. The screw nut has reasonable structure, easy manufacturing and good self-locking performance, so that the screw nut can not be loose under any condition of vibration.
Description
The utility model discloses a kind of nut, particularly a kind of V-type jump ring self-locking nut.
Someone once invented a kind of self lock nut, and (patent No.: ZL92245175.3), it is to rely on spring and frictional force bolt between the locked screw rod of internal diameter less than footpath in the bolt thread, realizes self-locking with this.Be used to put the friction that do not have between the large-diameter thread of spring and the spring in the nut design, require to have the gap more than the 0.1mm therebetween, large-diameter thread only plays the role of positioning, do not bear frictional force, this nut in course of working since the nut internal diameter be the reducing screw thread, difficulty of processing is big, and quality is difficult for guaranteeing that efficient is low.
The purpose of this utility model will provide a kind of V-type jump ring self-locking nut exactly, is processed with locating slot in the nut, and nut only adds a kind of screw thread, easy processing, and the efficient height, self-locking performance is good, can reduce production costs greatly.
For achieving the above object, the utility model adopts technological scheme as described below: V-type jump ring self-locking nut, comprise nut, jump ring, fixed hole or groove, locating slot and removal hole, be processed with the locating slot of an opening or edge sealing in the nut, jump ring is arranged in locating slot, and the tail end of jump ring is straight peen, elbow or circle cap, is fixed in the fixed hole, jump ring is made for the V-type spring steel by section, and removal hole is in the tangent position of locating slot and communicates with it.
Below in conjunction with accompanying drawing the utility model is said thin explanation.
Fig. 1 is the utility model cross-sectional schematic.
Fig. 2 is a schematic top plan view of the present utility model.
With reference to Fig. 1, Fig. 2.V-type jump ring self-locking nut, it comprises nut 1, jump ring 2, fixed hole or groove 3, locating slot 4, removal hole 5, be processed with the locating slot 4 of an opening or edge sealing in the nut, jump ring 2 is arranged in locating slot 4, the tail end of jump ring 2 is fixed in the fixed hole 3, tail end is made straight peen, elbow or circle cap to increase its pulling force, jump ring is made for the V-type spring steel by section, contact for face between jump ring and the bolt thread, frictional force is big, self-locking performance is good, thereby reduces the jump ring number of turns and nut thickness, thereby improves the mechanical property of nut.Also be processed with removal hole 5 on the nut, removal hole 5 is in the tangent position of locating slot and communicates with it, during dismounting, inserts removal hole with special tool, withstands the movable end of jump ring, unscrews nut again after the jump ring of locked screw rod is unclamped just can lay down.
The utility model is work like this: the V-type spring steel less than the diameter of thread that is contained in the interior locating slot 4 of nut is made spiral shell strand type jump ring along pitch, its tail end is fixed in the fixed hole, nut is when precession, screw mandrel is along the inboard helix precession of jump ring, jump ring is subjected to outwards to expand after the frictional force, make the screw rod precession, otherwise jump ring inside locked screw rod under frictional force action can not move back by pine nut under any vibration operating conditions.
Claims (3)
1, a kind of V-type jump ring self-locking nut, comprise nut (1), jump ring (2), fixed hole or groove (3), locating slot (4), removal hole (5), it is characterized in that: the locating slot (4) that is processed with a upper end open or edge sealing in the nut (1), jump ring (2) is arranged in locating slot, the tail end of jump ring is fixed in the fixed hole (3), and jump ring is that the spring steel of V-type bullet is made by section.
2, V-type jump ring self-locking nut according to claim 1 is characterized in that: removal hole (5) is in the tangent position of locating slot and communicates with it.
3, V-type jump ring self-locking nut according to claim 1 is characterized in that: the tail end of jump ring is straight peen, elbow or circle cap.
