Description
Technical field
The utility model belongs to hardware component technology field, and in particular to a kind of self-locking nut.
Background technique
Nut is relatively common one of hardware component, and conventional nut is in use due to other reasons such as vibrations
Understand voluntarily loose or dislocation, causes many security risks.Also occur many self-locking nuts in the market, working principle is usually with rubbing
Wiping power is self-locking, and many self-locking nuts also can voluntarily loosen in use for some time, however it remains security risk.
Utility model content
The purpose of the utility model is to overcome defects in the prior art, and provide it is a kind of reasonable in design, it is self-locking
Effect is good, a kind of self-locking nut that will not be loosened.
Purpose of the utility model is realized as follows: including nut body, the middle and upper part of nut body side wall and interior spiral shell
Through-hole is offered on the vertical direction of pit, interior card screw is coated in through-hole, and one end of through-hole is equipped with groove, groove and interior card
The size of nut on screw is adapted, and the intermediate position of interior card screw is recessed equipped with arc-shaped, the circular arc half of arc-shaped recess
The radius of the screw rod installed in diameter and internal thread hole is adapted, and is gradually extended on the circumference of card screw including arc-shaped recess, and
The radian of extension is gradually reduced, and the arc range opened up on card screw including arc-shaped recess is circular arc between 120 °~130 °
Shape is recessed the small position of radian equipped with screw thread, and the screw rod of interior card screw is equipped with screw thread.
Preferably, the material of the nut body and Nei Ka screw is stainless steel.
The utility model have it is reasonable in design, self-locking effect is good, will not loosen and not will cause the excellent of security risk
Point.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model nut.
Fig. 2 is the structural side view of the utility model nut.
Fig. 3 is the structural schematic diagram of card screw in the utility model.
Fig. 4 is the structure sectional view of Fig. 3.
Specific embodiment
In order to which the technical features, objects and effects to utility model are more clearly understood, Detailed description of the invention sheet is now compareed
The specific embodiment of utility model, identical label indicates identical component in the various figures.To make simplified form, in each figure
Part relevant to the utility model is only schematically shown, they do not represent its practical structures as product.
As shown in Figure 1,2,3, 4, the utility model is a kind of self-locking nut, including nut body 1,1 side wall of nut body
The middle and upper part direction vertical with internal thread hole 2 on offer through-hole 3, interior card screw 4, one end of through-hole 3 are coated in through-hole 3
Equipped with groove 5, groove 5 is adapted with the size of the nut 6 on interior card screw 4, and the intermediate position of interior card screw 4 is equipped with arc-shaped
Recess 7, the radius of screw rod 8 installed in the arc radius and internal thread hole 2 of arc-shaped recess 7 are adapted, and arc-shaped, which is recessed, 7 to exist
Gradually extend on the circumference of interior card screw 4, and the radian extended is gradually reduced, is opened up on card screw 4 including arc-shaped recess 7
Arc range is between 120 °~130 °, and the small position of arc-shaped 7 radians of recess is equipped with screw thread, is set on the screw rod of interior card screw 4
There is screw thread.The material of the nut body 1 and Nei Ka screw 4 is stainless steel.
When the utility model is used, being worn in through-hole 3 after installing upper screw rod in the internal thread hole 2 in nut body 1
Interior card screw 4 is loaded onto, nut 6 is just embedded in groove 5, and it is easy to disassemble, after interior card screw 4 has installed, in interior card screw 4
Between the arc-shaped recess at position 7 just matched with screw rod, start nutting ontology 1, after being screwed to a certain degree, further rotate
The radian of interior card screw 4, arc-shaped recess 7 extends to the small direction of radian, until locking cannot turn.The arc-shaped
The cup depth of recess 7 is just adapted with the tooth height of screw rod.
Preferably, the utility model prevents from corroding outdoors in use, material is selected as stainless steel.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, are integrally connected, are also possible to detachably connect
It connects；The connection being also possible to inside two elements；Can be directly connected, can also indirectly connected through an intermediary, for
For those skilled in the art, can understand as the case may be above-mentioned term in the present invention specifically contain
Justice.
