Abstract
The utility model discloses a tooth wedge type anti-loosing fastener, belonging to the fastener field of the engineering machine. The utility model solves the disadvantages of the easy loosing, infirmity or inconvenient use of the existing fastener. The utility model is formed by combining a screw thread connecting piece with a tooth wedge groove and a washer with a tooth wedge. When the utility model is used, because the tooth wedge tallies with the groove and the elastic force is generated by the washer, the utility model can easily achieves the anti-loosing purpose.
Description
The utility model belongs to the tightening technology field in the engineering machinery.
Known to the claimant, the threaded fastener anti-loose method mainly contains four kinds of methods at present.First kind is to adopt the locking mode that increases frictional force.Wherein have the elastic force that adopts elastic washer to flatten the back generation to increase frictional force, but reliability is not high.Adopt in addition double nut to top effect or utilize the elastic force of binding nut to increase frictional force, but be subjected to spatial constraints, the installing/dismounting inconvenience.Have again and adopt the method for the screw thread place of screwing embedding polyamide fibre to increase frictional force, but only be suitable for operating temperature less than 100 ℃ connection.Second kind is to adopt the method for machinery to be equipped with cotter pin as utilizing the hexagonal slotted nut; Utilize lock washer; Utilize the slot wedge wedging screw rod slotted eye gland nut of energy self-marketing; Penetrate the special hole of one group of bolt head with mild steel wire after, make its mutual restriction, but loading and unloading are inconvenient.The third is to adopt chemical method as screwing coating adhesive on the screw thread.Use this go up all will carry tackiness agent when method requires each the installation and need heat when back-outing, otherwise be difficult to dismounting.The 4th kind of method is to adopt riveting to dash or the method for spot welding, and such fastening piece only can disposablely use.
The purpose of this utility model is: at the deficiency of existing fastener locking technology, develop a kind of tooth locking type fastener, it can guarantee pretightening force, reaches locking purpose extremely reliably.
The utility model is design like this: form the tooth locking type fastener by a thread connector and a pad that has the tooth wedge that has tooth wedge groove; Tooth wedge groove is made up of a plurality of roundlet arc concave surfaces that are evenly distributed on the thread connector periphery, and the tooth wedge is to be evenly distributed on to fill up a plurality of small column convex surfaces compositions of going up on the corresponding position.Teeth groove on the thread connector be distributed in fill up the supporting surface that contacts on, tooth wedge on the supporting surface of pad and the tooth wedge groove on the thread connector match.In order to reduce the additional drag that is screwed into or back-outs, tooth wedge height can design very for a short time, and the acting surface of tooth wedge can become less angle with supporting surface.The shaped design archwise of pad is for well, tightens to flatten elastic force that the back produces with the realization pretightening force.
The utility model has the advantages that: as long as a tooth wedge groove on last tooth wedge of pad and the thread connector coincide, other tooth wedge all matches with tooth wedge groove.The screw thread of more every band supporting surfaces, bolt, screw, plug screw etc. can be designed to have the structure of tooth wedge groove on supporting surface.Because tooth wedge groove can dense distribution, thus the tooth on the pad be easy to thread connector on tooth wedge groove match.Guarantee pretightening force after tightening, reach locking purpose extremely reliably.The tooth locking type fastener can often remove and install, and is easy to use.
The contrast accompanying drawing is illustrated below.

For an embodiment.Thread connector in the utility model can be a nut.When using the utility model, at first pad is limited on coupled, the nut that will have tooth wedge groove then is screwed on the screw rod that passes pad and coupled, tightens and make tooth wedge on the pad and the tooth wedge on the nut and the tooth wedge groove on the nut to match.In vibration processes, this nut is difficult to and coupled relative movement, thereby plays locking effect effectively.
Claims (1)
1, tooth locking type fastener is characterized in that being made up of the thread connector (1) of band tooth wedge groove and the pad (2) that has a tooth wedge; Tooth wedge groove is made up of a plurality of roundlet arc concave surfaces that are distributed in the thread connector periphery, and the tooth wedge is to be evenly distributed on to fill up a plurality of small column convex surfaces compositions of going up on the corresponding position.
