Abstract
An anti-looseness anti-drop nut comprises a nut body, small bolts and rubber gaskets. The anti-looseness anti-drop nut is characterized in that a pair of symmetrical sides of the nut is provided with bolt holes and matched small bolts, the rubber gaskets are embedded in the bolt holes, and each lead angle is 1.5 degrees. A cross groove is arranged at the top of a bolt head of each small bolt, a screwdriver can be used to screw the small bolts in when a small spanner is not available, and accordingly the usage is facilitated. When in use, the nut is located, the small bolts are screwed in, and the bottoms of the small bolts abut against the rubber gaskets, thereby enabling the rubber gaskets to be filled into the clearances between the nut and the matched bolts due to deformation, enhancing friction and achieving the aim of preventing looseness and drop.
Description
Technical field
The utility model relates to technical field of fastening, is a kind of locking screwed retaining ring specifically.
Background technique
Being threaded is one of common mechanical connection, the part and nut is absolutely necessary in great majority are threaded, because the vibration of machinery makes this ease of connection occur getting loose, thus the working life that makes vibration aggravate to produce noise and can reduce machine.
Summary of the invention
The purpose of this utility model addresses the above problem exactly, provide a kind of can locking screwed retaining ring.
The technological scheme that the utility model is adopted for achieving the above object is: a kind of can locking screwed retaining ring, comprise nut body, stove bolt and rubber sheet gasket, it is characterized in that: on a pair of symmetrical side of nut, offer bolt hole and add a supporting stove bolt, two bolts hole are only joined a stove bolt, be for when one of them hole is blocked, can use another hole, the inner end of bolt hole all is embedded with a rubber sheet gasket in addition, lead angle is 1.5 °, so higher self-locking performance can be arranged, the bolt head top of stove bolt is provided with cross recess, when not having small wrench, can be screwed into convenient the use with screw-driver.In use, after nut had good positioning, stove bolt is screwed into, the stove bolt bottom can withstand on the rubber sheet gasket again, and rubber sheet gasket will stress deformation and be filled to the space of nut bolt supporting with it like this, thereby increase frictional force therebetween plays locking purpose.
The utility model there is no report both at home and abroad at present.
Description of drawings
Accompanying drawing 1 is the plan view that the utility model adds stove bolt.1 is nut body, and 2 is rubber sheet gasket, and 3 is stove bolt, and 5 is bolt hole.
Accompanying drawing 2 is plan views that the utility model adds stove bolt.1 is nut body, and 3 is stove bolt, and 4 is cross recess.
Accompanying drawing 3 is plan views that the utility model does not add stove bolt.1 is nut body, and 2 is rubber sheet gasket, and 5 is bolt hole.
Accompanying drawing 4 is plan views that the utility model does not add stove bolt.1 is nut body, and 2 is rubber sheet gasket.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.Referring to accompanying drawing 1.Accompanying drawing 1 is the plan view that the utility model adds stove bolt.Mainly comprise nut body 1, rubber sheet gasket 2, stove bolt 3, bolt hole 5.
The use condition of nut is as follows: in use, stove bolt 3 is screwed into from one of them hole 5 on the nut body 1, after being screwed into certain distance, the bottom of stove bolt 3 can withstand on the rubber sheet gasket 2, rubber sheet gasket 2 will stress deformation and is filled to nut body 1 and matches with it in space of bolt like this, frictional force between bolt thereby increase nut body 1 matches with it plays locking purpose.In addition, the bolt head top of stove bolt 3 is provided with cross recess 4, when not having small wrench, can be screwed into screw-driver, the convenient use.
Claims (3)
1. a locking screwed retaining ring is characterized in that, offers bolt hole on a pair of symmetrical side of nut, and adds a supporting stove bolt.
2. locking screwed retaining ring according to claim 1, its feature are that also the inner end of bolt hole is embedded with a rubber sheet gasket.
3. locking screwed retaining ring according to claim 1, its feature also are, are provided with cross recess at the bolt head top of stove bolt.
