Description
Technical field
The utility model relates to technical field of fastening, more particularly, to a kind of new type nut locking device.
Background technique
Currently, various machines are applied with the high speed development of country, in various machinery, equipment, vehicle,
Railway, ship etc. above, have used various locking devices；Existing clamp device is mostly that nut or double nut and bolt connect
Connect fastening means, as plain bolt pair.For often tearing the metal structure product of fortune open, this plain bolt pair is in disassembly process
In provide convenience, and some metal structures are not dismantled for a long time, due to not having the plain bolt pair using locking measures to connect
It does not fasten, everlasting, by exposing to wind and rain or under the effect of fierce shock loads, plain bolt pair will appear loosening now
As major accident occurring, causes extreme loss if causing to connect unstable or nut and falling off without finding to overhaul in time.
Utility model content
To solve the deficiencies in the prior art, the technical problems to be solved in the utility model is to prevent nut because of shake at work
Dynamic or extraneous factor and loose or dislocation, to solve the above-mentioned problems, the utility model provides a kind of new type nut locking device.
A plain nut is arranged on the bolt 1 for a kind of new type nut locking device, including bolt 1 and installation base surface 7
2 and a fixed device；The plain nut 2 face on the securing means.
The fixed device includes L-type fixing piece, and secondary bolt 5 and abaculus 6, the L-type fixing piece include right angle block 4 and spiral shell
Mother 3,4 bottom side of right angle block is fixedly connected with nut 3；4 top of right angle block is equipped with tapped through hole, auxiliary connection bolt 5.
The L-type fixing piece includes L-type metal block 8, and the L-type metal block is made of the vertical bending of straight metal block；Institute
8 bottom of L-type metal block is stated equipped with tapped through hole, connects bolt 1, top is equipped with tapped through hole, connect with secondary bolt 5.
Abaculus 6 is equipped between the L-type fixing piece and plain nut 2, the abaculus 6 is equipped with tapped through hole, with secondary bolt 5
Connection.
Compared with the existing technology, the utility model, the structure is simple, easy to manufacture, and installing and dismounting is easy, anti-loosing effect
It is good, it is reusable, it is the nut anti-looseness device easily promoted.

Specific embodiment
As shown in Fig. 1 to 6, a kind of device for nut anti-looseness of the utility model includes bolt 1 and installation base surface 7, spiral shell
Bolt 1 is vertically mounted on installation base surface 7, and bolt 1 is equipped with plain nut 2 and fixed device, and plain nut 2 is on the securing means
Face.Fixed device includes L-type fixing piece, and secondary bolt 5 and abaculus 6, the L-type fixing piece include right angle block 4 and nut 3, right angle
4 bottom side of block is fixedly connected with nut 3, and 4 top of right angle block is equipped with tapped through hole, auxiliary connection bolt 5, L-type fixing piece
Abaculus 6 is equipped between plain nut 2,6 top of abaculus is equipped with tapped through hole, connect with secondary bolt 5, make secondary 5 He of bolt in this way
Plain nut 2 can preferably be connected and fixed.
As shown in Fig. 7 to 8, L-type metal block 8 is made of the vertical bending of straight metal block, and 8 bottom of L-type metal block is equipped with spiral shell
Line through-hole, connects bolt 1, and top is equipped with tapped through hole, connect with secondary bolt 5.It is equipped between L-type fixing piece and plain nut 2
Abaculus 6,6 top of abaculus are equipped with tapped through hole, connect with secondary bolt 5.
The working principle of the utility model is as follows:
Secondary bolt 5 passes through fixed device and abaculus 6 holds out against plain nut 2, so that abaculus 6 is close to the side of plain nut 2,
When plain nut 2 will loosen, the side that on the one hand secondary bolt 5 presses closer plain nut 2 loosen it can not, on the other hand
Because nut 2 loosens side offset can occur for abaculus 6, and at this moment secondary bolt 5 can not be loosened again due to 6 lateral deviation of abaculus, finally be made
At the interlocking phenomenon between nut 2, abaculus 6 and secondary bolt 5, as shown in fig. 6, in the effect of secondary bolt 5 and L-type fixing piece
Under, plain nut 2, by opposite shearing force, generates eccentric pretightning force with bolt 1 respectively and tightly engages with nut 3, realizes
Locking thread, when nut installs this device, being threadedly coupled with any installation base surface 7 can all be fastened, and reach excellent locking
Effect.
L-type metal block 8 can be considered the equivalence replacement for the L-type fixing piece being made of right angle block 4 and nut 3.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
