Description

Nut

The present invention relates to a nut, in particular to an elastic gasket and a positioning piece on the nut body, which can be locked and secured by the elastic positioning of the elastic gasket and the positioning piece. .

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. The biting force is to prevent the nut 12 from coming loose, but the effect of preventing the loosening of the lock is limited, and when the lock is locked, the C-shaped washer 13 is first set on the screw or the bolt 10, and then the nut 12 is placed. The screw is locked on the screw or bolt 10, which is time consuming and troublesome in assembling and locking.

The purpose of this creation is to provide an effective solution to the shortcomings of conventional nuts in use.

The nut of the present invention is mainly composed of a nut body, an elastic gasket and a positioning piece, wherein the nut body is provided with an inner screw hole, and one end of the nut body is provided with a connecting portion, a guiding hole is disposed in the connecting portion, the guiding hole is connected to the inner screw hole, and the elastic spacer and the positioning piece are sequentially sleeved on the connecting portion of the nut body, the elastic spacer and the A through hole is formed in the middle of the positioning piece for the connecting portion of the nut body, and the aperture of the elastic pad and the positioning piece is larger than the hole An outer diameter of the connecting portion of the nut body, wherein the two side wall surfaces of the elastic spacer are oppositely inclined, the outer side of the positioning piece is provided with a groove, and the end edge of the connecting portion of the nut body is bent The fastening portion is fastened into the groove of the positioning piece, and the fastening portion is configured to fasten the elastic spacer and the positioning piece to the connecting portion of the nut body.

The nut of the present invention, wherein a middle portion of the elastic spacer forms a gap with an intermediate portion of the positioning piece.

The nut of the present invention has the advantages that the anti-loose effect can be achieved, and the elastic gasket and the positioning piece are combined on the nut body, which is more convenient in assembly.

For the purpose of achieving the above-mentioned purpose and function of the above-mentioned use, the preferred embodiments are described in the following, and the details are as follows: For the embodiment of the present application, please refer to the second figure. The main body is provided with a nut body 2, an elastic spacer 3 and a positioning piece 4, wherein the nut body 2 is provided with an inner screw hole 20, and one end of the nut body 2 is connected. The connecting portion 21 is provided with a guiding hole 22, and the guiding hole 22 is connected In the inner screw hole 20, the elastic spacer 3 and the positioning piece 4 are sequentially sleeved on the connecting portion 21 of the nut body 2, and the elastic spacer 3 and the positioning piece 4 are provided in the middle. The connecting portion 21 of the nut body 2 is provided with the through holes 30 and 40. The apertures of the elastic spacers 3 and the through holes 30 and 40 of the positioning piece 4 are larger than the outer diameter of the connecting portion 21 of the nut body 2, The two side walls of the elastic spacer 3 are provided with a chamfered surface 31 in the same direction. The middle portion of the elastic spacer 3 forms a gap A with the middle portion of the positioning piece 4, and a groove is formed on the outer side of the positioning piece 4. The end of the connecting portion 21 of the nut body 2 is bent into a fastening portion 23, and the fastening portion 23 is fastened in the recess 41 of the positioning piece 4, and the fastening portion 23 is to be The elastic spacer 3 and the positioning piece 4 are fastened and positioned on the connecting portion 21 of the nut body 2, and thus are a nut structure.

When assembling, please refer to the second to fifth figures. First, the elastic spacer 3 and the positioning piece 4 are sleeved on the connecting portion 21 of the nut body 2, so that the end edge of the connecting portion 21 is set in the positioning piece 4. In the groove 41, the end edge of the connecting portion 21 of the nut body 2 can be bent into a fastening portion 23 by mechanical automatic punching, and the fastening portion 23 is fastened in the groove 41 of the positioning piece 4. The positioning piece 4 and the elastic spacer 3 are fastened and positioned on the connecting portion 21 of the nut body 2. Thus, the creation is completed by mechanical automatic assembly, and the assembly is very convenient and fast.

When in use, please refer to the fifth or sixth figure, screw the nut body 2 on the screw or bolt 10 which is placed on the object 11, so that the end of the screw or bolt 10 is guided along the nut body 2. The lead hole 22 is introduced into the inner screw hole 20 to be screwed. When the nut body 2 is locked on the screw or the bolt 10, the elastic gasket 3 abuts against the nut body 2 on the side of the nut body 2 and is subjected to a nut. The body 2 is pressed and elastically deformed such that the other side of the chamfered surface 31 abuts against one side of the positioning piece 4 (as shown in FIG. 6 ), and the elastic spacer 3 and the positioning piece 4 are formed. The gap A is reduced or disappeared, and the other side of the positioning piece 4 abuts against the surface of the object 11 to form an elastic abutting force, which can increase the biting force of the screw hole 20 of the nut body 2 when the screw is locked. In this way, the nut body 2 can be prevented from being loosened due to vibration or external force, and the elastic gasket 3 and the positioning are prevented. The sheets 4 are attached to the nut body 2 without being assembled one by one, so that it is more convenient to assemble and lock on the object 11.

In summary, the present invention has achieved the intended use and effect, and is more desirable and practical than the prior art. However, the above embodiments are only specifically described for the preferred embodiment of the present invention. This embodiment is not intended to limit the scope of the present invention, and all other equivalents and modifications may be included in the scope of the invention covered by the present invention.
