Description

Nut 【0001】

The present invention relates to a nut, in particular to a cap and a washer on the body of the nut, which can achieve the function of locking and double anti-loose by the tight positioning of the washer, and the cap cover It is located at the end of the screw or bolt to prevent collision and injury, and has the function of being beautiful and safe.

【0002】

Pressing, generally used to match the screw or bolt 10 to lock the nut 12 of the object 11, as shown in the first figure, which is mainly provided with a screw hole 120 in the nut 12, however, the conventional nut 12 When the screw is screwed on the screw or the bolt 10, it is easy to loosen due to vibration or external force. Therefore, it is generally attached to the C-shaped washer 13 between the nut 12 and the object 11 to increase the nut 12 screw lock. Bite force to prevent the nut 12 from loosening, but the effect of preventing the loosening of the lock is limited; and after the screw or the bolt 10 and the nut 12 are screwed, the end of the screw or the bolt 10 protrudes from the screw On the outer side of the cap 12, if it is accidentally bumped, there will be an injury, and the end of the screw or bolt 10 is exposed to rust, which is extremely unattractive and will affect its screwing effect.

The slab is disposed in a chamber of the connecting portion of the nut body, and a hole is formed in the middle of the stalk, and the hole diameter of the hole is slightly smaller than the hole diameter of the screw hole in the nut body;
The cap is disposed on the connecting portion of the nut body, and the periphery of the cap is provided with a flange, and the flange of the cap is disposed in the chamber of the connecting portion of the nut body and abuts against the washer The end edge of the connecting portion of the nut body is punched inwardly to form a fastening portion, and the fastening portion can be used to fasten the cap and the washer to the connecting portion of the nut body.

[0005]

The nut of the present invention, wherein a middle portion of the flange of the nut body is provided with a tapered taper hole communicating with the inner screw hole, the tapered taper hole being convenient for inserting a screw or a bolt and screwing into the inner screw hole Inside.

[0006]

The nut of the present invention has the advantages of double anti-loose effect, and the cap cover is arranged at the end of the screw or the bolt to prevent collision and injury, and has the function of being beautiful and safe.

For the purpose of achieving the above-mentioned purpose and effect of the above-mentioned use, a preferred and feasible embodiment will be described, and the details are as follows:

【0009】

For the embodiment of the present invention, as shown in the second figure, a nut body 2 is mainly provided, and the nut body 2 is provided with an inner screw hole 20, and one end of the nut body 2 is provided with a flange 21, The end surface of the flange 21 is provided with a chamfered surface 22 cut inwardly from the middle portion. The middle portion of the flange 21 is provided with a tapered taper hole 23 communicating with the inner screw hole 20, and the other end of the nut body 2 is provided with a connecting portion. 24, the connecting portion 24 is provided with a chamber 25; a washer 3 is disposed in the chamber 25 of the connecting portion 24 of the nut body 2, and a through hole 30 is defined in the middle of the washer 3, and the through hole 30 is The aperture is slightly smaller than the aperture of the inner screw hole 20 of the nut body 2; a cap 4 is disposed on the connecting portion 24 of the nut body 2, and the periphery of the cap 4 is provided with a flange 40, the flange 40 is disposed in the chamber 25 of the connecting portion 24 of the nut body 2, and thus is a nut structure.

[0010]

When assembling, please refer to the second to fourth figures. First, the washer 3 is placed in the chamber 25 of the connecting portion 24 of the nut body 2, and the cap 4 is placed in the joint portion of the nut body 2. The flange 40 of the cap 4 is placed on the washer 3, and the end edge of the connecting portion 24 of the nut body 2 is punched inwardly to form a fastening portion 26, which is fastened. The portion 26 fastens the cap 4 and the washer 3 to the connecting portion 24 of the nut body 2, so that assembly can be completed.

[0011]

When in use, please refer to the fifth figure, screw the nut body 2 to the screw or bolt 10, so that the end of the screw or bolt 10 is introduced into the inner screw hole 20 along the inclined taper hole 22 of the nut body 2. A screw lock, a screw or bolt 10 is screwed into the perforation 30 of the washer 3, and the end of the screw or bolt 10 is inserted into the cap 4, and the end of the screw or bolt 10 is covered by the cap 4. When the nut body 2 is locked on the screw or the bolt 10, the chamfered surface 22 of the end surface of the flange 21 of the nut body 2 is pressed against the surface of the object 11 to form an elastic resistance. The force can increase the bite force when the inner screw hole 20 is screwed, and the washer 3 in the chamber 24 of the nut body 2 can further increase the bite force when the nut body 2 is screwed, thereby preventing the screw The cap body 2 is loosened due to vibration or external force. The creation has a double anti-loose effect, and the cap 4 is placed at the end of the screw or bolt 10 to prevent collision and injury, and the screw or bolt 10 The end is not exposed, and it has the function of being beautiful and safe.
