Description

Anti-loose gasket structure

The present invention provides a anti-loose gasket, in particular, a screw and the first and second gaskets have an axial and radial interlacing force, so that the screw and the gasket are not affected by the long-term Vibrating and loose anti-loose gasket structure.

Press, the main function of the screw and nut is to lock or fix the item. If the locked item is a stationary object, there is no problem of looseness; if it is used on a machine or vehicle that is always running, it must be Effectively prevent the looseness of the screw or nut, otherwise the damage of the object or the danger of the human body may occur; the reason for the looseness of the screw or the nut is mainly vibration, and the long-term vibration will cause the nut or the screw to rotate. To make the nut or the screw produce a slight rotation. After a long period of operation, the nut or the screw will loosen or loosen or become loose. Therefore, there is a conventional anti-loose screwing method. The first one is that the most common way on the market is to lock the screw. A gasket (was) is added between the lock and the screw. The function of the gasket is to increase the friction coefficient so that the workpiece can Locking reduces the possibility of loosening during use. However, it is generally considered that the above-mentioned anti-loose screwing method is not safe enough to cause looseness; the second is that the anti-loose nut structure is utilized by the top end of the main screw hole. , The impact to be non-circular The local contour of the internal thread of the top end portion is inwardly deformed, and the conventional nut is prevented from loosening due to vibration by the internal thread of the retracted deformation abutting against the stud of the screw, however, When the conventional anti-loose nut is actually used, only the anti-loose nut can be locked in one direction, and there is no mechanism for withdrawing the nut, and the anti-loose nut is quite time-consuming to implement the locking. Therefore, after the screw-proof nut is screwed and positioned, it cannot be repeatedly loaded and unloaded, which seriously causes inconvenience and disturbance to the constructor.

Therefore, how to solve the above problems and shortcomings in the past, that is, the creators of the creation and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, the creators of this creation, in view of the above-mentioned deficiencies, are collecting relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed such application screws and first The second gasket has the axial and radial interlacing force, so that the screw and the gasket are not patented by the anti-loose gasket structure which is loosened by vibration for a long time.

The main purpose of this creation is to make the screw and the first and second spacers have the axial and radial urging force at the same time, so that the screw, the first gasket and the second gasket are The screwing relationship is released without vibration.

For the above purposes, the present invention is a tamper-proof gasket structure, the main structure comprising at least one first gasket and a second spacer is formed, a first rough surface is formed on one side of the first spacer, and a first friction surface is formed on the other side, and a first roughness is formed on one side of the second spacer. The faces are mutually jammed with a second rough surface and the other side is formed with a second friction surface.

With the above-mentioned structural composition, the screw and the first and second spacers have an axial and radial interlacing force at the same time, so that the screw and the gasket are not detached by vibration.

In order to achieve the above objectives and effects, the technical means and structure adopted by the present invention are described in detail in the preferred embodiment of the present creation, and the features and functions are as follows.

Please refer to the first figure, which is a perspective view of a preferred embodiment of the present invention. It can be clearly seen from the figure that the present anti-loose gasket structure comprises: at least one first gasket 1, the first gasket 1 is formed with a first rough surface 11 on one side, and a first friction surface 12 is formed on the other surface, the first rough surface 11 is composed of a plurality of first tooth portions 111; and at least one second spacer 2 The second pad 2 is formed with a second rough surface 21 that is engaged with the first rough surface 11 on one side, and a second friction surface 22 is formed on the other surface. The second rough surface 21 is composed of several The second tooth portion 211 is formed.

With the above structure and composition design, the following is the use of this creation. Please refer to the same section. 2 and 2 are a schematic view of the first embodiment of the preferred embodiment of the present invention. As can be clearly seen from the drawing, the first rough surface 11 on the first spacer 1 is used. And the second rough surface 21 on the second gasket 2 and the two correspond to each other, and then placed on the screw hole to be locked, at this time, the screws are sequentially inserted into the first gasket 1 and the second gasket 2 and drilled in. In the workpiece 4, the first rough surface 11 and the second rough surface 21 are gradually clamped to each other while the screw is locked into the workpiece 4. When the screw is locked, the screw and the first gasket 1 are visible. The first friction surface 12 is attached, and the second friction surface 22 on the second spacer 2 is attached to the surface of the workpiece 4, and the first rough surface 11 and the second rough surface 21 are respectively attached to the screw and the workpiece 4. Therefore, the frictional force of the first rough surface 11 and the second rough surface 21 is so large that the screw is not easily loosened after being screwed.

Please also refer to the third embodiment, which is a schematic diagram of a preferred embodiment of the present invention. It can be clearly seen from the figure that the first embodiment 1a and the second spacer 2a are The screw system cooperates with the angle iron 3a and is applied to the back hole method to strengthen the fixed strength of the stone and the wall surface to achieve another implementation purpose.

However, the above description is only a preferred embodiment of the present invention, and thus does not limit the scope of the patent of the present invention. Therefore, all the simple modifications and equivalent structural changes using the present specification and the schema should be the same. It is included in the scope of this creation patent and is given to Chen Ming.

Therefore, please refer to all the drawings. When using this design, compared with the conventional technology, there are the following advantages: the use of the first gasket 1 and the second gasket 2 simultaneously have an axial and radial compression Force to make the screw loose without being vibrated when locked.

In summary, the anti-loose gasket structure of this creation can achieve its efficacy and purpose when it is used. Therefore, this creation is a practical and excellent creation, which is in line with the application requirements of the new patent. To apply, I hope that the trial committee will grant this creation as soon as possible to protect the hard work of the creators. If there is any doubt in the ruling committee, please do not hesitate to give instructions, the creators will try their best to cooperate and feel good.
