Abstract
The utility model relates to a vibration-reducing friction-increasing anti-loose screw, which can effectively solve the problem that the screw is easy to loose at the position of vibration.
Description
Technical Field
The utility model relates to the field of machinery, in particular to a vibration-damping friction-increasing anti-loosening screw.
Background
When a vehicle is started to normally run, the vehicle is suddenly flamed out sometimes, and the situation that the power supply screw is loosened and poor contact is caused is found through examination, so that the vibration of rail traffic is considered to be larger, and once the screw at a key position is loosened, a great safety problem is probably caused to a train, so that a check screw which is low in cost, simple in structure and convenient to use cannot be invented is a technical problem which needs to be solved urgently at present.
Disclosure of Invention
In view of the above situation, the present invention provides a vibration-damping friction-increasing anti-loosening screw, which can effectively solve the problem that the screw is easy to loosen at the vibrating position.
The technical scheme includes that the anti-skid nut comprises a screw and a nut, a conical rubber gasket is arranged on the screw, a conical cavity matched with the conical rubber gasket is arranged at the bottom of the nut, the volume of the conical rubber gasket is larger than that of the conical cavity, and anti-skid grains are arranged on the inner wall of the conical cavity.
The screw loosening prevention device is simple in structure, reasonable in design, convenient to use and low in cost, effectively solves the problem of screw loosening, is suitable for rail vehicles and equipment or machines with large vibration in the mechanical manufacturing industry, and is an innovation on screws.
Drawings
FIG. 1 is a schematic cross-sectional view of the structure of the present invention.
Fig. 2 is a schematic structural section view of the nut of the present invention.
Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in figures 1-2, the anti-skid nut comprises a screw rod and a nut, wherein a conical rubber gasket 2 is arranged on the screw rod 1, a conical cavity 4 matched with the conical rubber gasket 2 is arranged at the bottom of the nut 3, the volume of the conical rubber gasket 2 is larger than the volume of the conical cavity 4, and anti-skid grains 5 are arranged on the inner wall of the conical cavity 4.
In order to ensure the using effect, the anti-skid threads 5 are axial vertical threads.
The bottom of the nut 3 is provided with anti-skid teeth 6.
The nut 3 is in a convex shape without a bottom sealing, and the conical cavity 4 is arranged at the bottom of the convex shape.
The inner wall of the convex upper part of the nut 3 is provided with an internal thread which is matched with the external thread on the screw rod 1.
The conical rubber gasket 2 is arranged along the circumference of the screw rod 1.
The diameter of the conical rubber gasket 2 is the largest in the middle and gradually reduced towards two ends, namely the conical rubber gasket is in a shape that an inverted cone and a forward cone are connected into a whole.
It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and not intended to limit the present invention in any way, and those skilled in the art can make modifications or equivalent variations to the above-mentioned embodiments without departing from the scope of the present invention.
The nut comprises a screw, a nut and a conical rubber gasket, wherein a conical cavity matched with the conical rubber gasket is formed in the nut, the volume of the conical rubber gasket is larger than that of the conical cavity, the conical rubber gasket can fully hold the screw and fill the conical cavity after the screw is tightened, the friction force between the nut and the screw is increased, axial hard threads are formed in the inner wall of the conical cavity of the nut and used for increasing the friction force between the conical cavity of the nut and the conical rubber gasket, and further, anti-skidding teeth are arranged on the periphery of the bottom of the nut to ensure that the screw cannot loosen.
The screw loosening prevention device is simple in structure, reasonable in design, indistinguishable from a common screw in appearance, good in using effect, suitable for rail vehicles and machinery manufacturing industry, equipment or machines with large vibration, innovative in screw and good in economic and social benefits, and effectively solves the problem of screw loosening.
