Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present utility model, preferred embodiments of the present utility model will be described below with reference to specific examples, but it should be understood that these descriptions are only for further illustrating the features and advantages of the present utility model, and are not limiting the patent claims of the present utility model. 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.

The utility model will be further described with reference to the drawings and preferred embodiments.

Example 1

Referring to fig. 1 to 3, a hexagonal washer self-drilling screw according to the present embodiment includes a screw body 10, wherein one end of the screw body 10 is provided with a hexagonal washer head 11, the other end is provided with a drill tail 12, and a combined washer 20 close to a hexagonal Hua Sitou is sleeved on the screw body 10; the combined washer 20 is formed by coaxially arranging and combining two C-shaped washers 21 with the same shape and size, an opening 22 is arranged on the C-shaped washer 21, and the openings 22 on the two C-shaped washers 21 are arranged in a staggered mode.

Further, a positioning protrusion 23 and a positioning groove 24, which are inserted and fitted with each other at 180 degrees apart from each other, are provided on one end surface of the C-shaped gasket 21.

Further, two positioning protrusions 23 and two positioning grooves 24 are provided on the same C-shaped washer 21.

Further, the positioning protrusions 23 are symmetrically disposed at two sides of the opening 22; the positioning projection 23 is adjacent to the opening 22.

Further, the C-shaped gasket 21 is made of rubber material or silicone material.

In the present embodiment, by assembling two C-shaped washers 21 to one end of the screw body 10 near the hexagonal washer head 11 in the radial direction of the screw body 10, the screw body 10 can pass through the opening 22 and enter the center of the C-shaped washer 21 due to the arrangement of the opening 22 and the deformation capability of the C-shaped washer 21 itself, so that the C-shaped washer 21 can be quickly completed; and the positioning protrusion 23 on any C-shaped gasket 21 faces the other C-shaped gasket 21, and the proper position is adjusted circumferentially, so that the positioning protrusion 23 on one C-shaped gasket 21 is fit and inserted into the positioning groove 24 on the other C-shaped gasket 21, and the two C-shaped gaskets 21 are combined to form a combined gasket 20 in a closed ring shape.
