Abstract

The utility model relates to a novel easy lock nut, which is mainly characterized in that a nut cap body is at least provided with three small screwed holes which are uniformly distributed on a nut cap body which has concentric circle with the nut cap body, the small screwed holes penetrate through the nut cap body, and are provided with small bolts. The novel easy lock nut has the advantages that since the nut cap body is at least provided with the three small screwed holes, and the small screwed holes are uniformly distributed on the nut cap body which has concentric circle with the nut cap body, the small screwed holes penetrate through the nut cap body, and are provided with the small bolts, the force required to lock the nut can be shared by a plurality of small bolts, and labor intensity for locking the nut can be reduced; since the small bolt is an inner-hexagon bolt, the bolt is difficult to be dismantled by a wrench, particularly a spring washer is provided, the bolt is not easy to loose; and since the nut cap is also provided with the spring washer, the spring washer keeps larger friction with the construction member body under the pressing of the small bolt.

Description

Novel easy locking nut
Technical field
The utility model relates to a kind of novel easy locking nut, especially a kind of novel easy locking nut.
Background technique
Nut is a kind of public's a fastening piece, at present, the nut check mode generally is by spanner nut directly to be applied screw-down torque, because the area of contact of nut bottom surface and member is bigger, causes frictional force to increase, nut is required great effort in tightening very much, particularly when nut body center screw is big, often need use large-scale spanner when fastening, also need to add long lever sometimes, make a concerted effort to lock by many people, perhaps use Hydraulic wrench.These modes are not only required great effort, and also need to depend on special tool.
A kind of easy locking nut can be arranged, and is Professional visitors's hope always.
Summary of the invention
The purpose of this utility model is, the effort that exists when the locking at existing nut, especially large-scale nut maybe needs to depend on the practical problem of special tool, and a kind of new locking nut is provided.
The purpose of this utility model is achieved in that a kind of novel easy locking nut, comprise nut body, it is characterized in that: three minor thread holes are set on the described nut body at least, they are evenly distributed on the nut body with nut body concentric circumferences, described minor thread hole connects the nut body, and is furnished with small-sized bolt.
In the utility model: described nut body center screw has 15mm at least.
In the utility model: described nut body is tetragonal nut or hexagon nut.
In the utility model: described small-sized bolt be small-sized in corner bolt, especially adopt small-sized in four corner bolts or small-sized hexagon socket head cap screw.
In the utility model: described nut body is furnished with pad, and described small-sized interior corner bolt is furnished with compression spring.
Advantage of the present utility model is: because three minor thread holes are set on the nut body at least, they are evenly distributed on the nut body with nut body concentric circumferences, described minor thread hole connects the nut body, and is furnished with small-sized bolt, the power of required usefulness will be shared by some stove bolts during locking nut, the labor intensity in the time of will alleviating locking nut; Because stove bolt is interior corner bolt, spanner is difficult to dismounting, especially dispose compression spring after, be difficult for loosening; Because the nut body also is furnished with pad, under the compressing of stove bolt, has kept bigger friction with member bodies.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the structural representation that Fig. 1 overlooks state.
Sectional view when Fig. 3 is the utility model locking operation.
Among the figure: 1, plain washer, 2, nut body, 3, small-sized in corner bolt, 4, spring washer, 5, the interior angle spanner.
Disclose the utility model embodiment's concrete structure in the accompanying drawing without limitation, the utility model embodiment has been described further below in conjunction with accompanying drawing.
By Fig. 1 Fig. 2 as seen, the utility model is provided with three minor thread holes at least on nut body 2, they are evenly distributed on the nut body 2 with nut body 2 concentric circumferences, and described minor thread hole connects the nut body, and be furnished with small-sized in corner bolt 3 and spring washer 4.
In the present embodiment, also be provided with plain washer 1 between described nut body 2 and the member, described nut body 2 is positive hexagon nut, and six minor thread holes have evenly distributed on the nut body 2, and be furnished with small-sized interior corner bolt 3, described small-sized interior corner bolt 3 is small-sized hexagon socket head cap screw.
During concrete enforcement, described nut body 2 also can be selected positive hexagon nut, and four minor thread holes evenly distribute on the nut body 2; Described small-sized interior corner bolt 3 also can be selected small-sized interior four corner bolts.
During concrete enforcement, the utility model be mainly used in center screw greater than 15mm than big nut.
As seen from Figure 3, in the use, should be earlier with one plain washer 1 of suit on screw rod, then with nut body 2 pretensions on screw rod, by the interior angle spanner the small-sized interior corner bolt 3 on the nut body 2 is screwed at last, make it be tight against plain washer 1, increase the frictional force between plain washer 1 and the member.
As seen, as long as, tighten interior hexagonal stove bolt,, very laborsaving by with joint efforts big nut being locked of all some stove bolts by behind handgrip nut body 2 pretensions.
