Detailed Description

The following description of the embodiments of the present utility model will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1, 2 and 3, the waterproof screw comprises a nut 1, a screw rod 2 and a gasket 3, wherein one end of the screw rod 2 is provided with a reinforcing column 4 for increasing torsion, the reinforcing column 4 and the screw rod 2 are integrated, at least part of the screw rod 2 is provided with a thread 5 for meshing, the length of the thread 5 can be adjusted as required, the thread 5 is close to one side of the reinforcing column 4, the gasket 3 is sleeved on the screw rod 2, the gasket 3 has a certain thickness, the covered area of the gasket 3 is larger than that of the nut 1, the gasket 3 is positioned on the periphery between the reinforcing column 4 and the thread 5, the gasket 3 is provided with a waterproof pad 6 for waterproof, and meanwhile, the waterproof pad 6 has compressibility.

The diameter of the reinforcement post 4 is greater than the diameter of the screw 2 so that more torsion can be accommodated, in this case the diameter of the reinforcement post 4 is smaller than the diameter of the nut 1.

The reinforcing column 4 has a round surface on one side close to the screw rod 2, which is beneficial to better fixing the gasket 3 on one hand and has a buffer function on the other hand.

The screw 2 is provided with all threads 5, and the screw 2 may be provided with all threads 5 as required.

The waterproof pad 6 is located near one side of the thread 5, and is elastic and waterproof, and meanwhile, if the vibration occurs, the mutual friction is reduced, and the vibration and noise are reduced.

As shown in fig. 4, two opposite sides of the nut 1 have a clamping plane, which is used for rotating, and is better than a screw hole, the screw hole is deformed or broken when being matched with a screwdriver to rotate for a long time, a clamping space is formed between the gasket 3 and the nut 1, and the clamping can also play a role of fixed connection.

The above embodiments are only for illustrating the technical concept and features of the present utility model, and are intended to enable those skilled in the art to understand the present utility model and to implement the same, but are not intended to limit the scope of the present utility model, and all equivalent changes or modifications made according to the spirit of the present utility model should be included in the scope of the present utility model.
