Detailed Description
The essential features and advantages of the utility model will be further elucidated with reference to the examples, without however being limited to the embodiments listed.
As shown in fig. 1 to 5, an automotive bolt locking device of the present embodiment includes a bolt 1 and a washer 2, a seal portion 3 is provided above the washer 2, the seal portion 3 has a boss portion 31, a base portion 32 and a through hole 33, the boss portion 31 is located above the base portion 32, and the through hole 33 penetrates the seal portion 3, so that the bolt 1 can pass through the seal portion 3. Above the protruding portion 31, a mating ring 4 is provided, and the mating ring 4 is made of a flexible material. The bolt 1 comprises a rod body 11 and a head 12, an annular part 13 is arranged at the bottom of the head 12, a containing cavity 14 is formed between the annular part 13 and the rod body 11, and the adapter ring 4 is arranged in the containing cavity 14 and sleeved in the rod body 11, so that the adapter ring 4 is convenient to install. The diameter of the mating ring 4 is larger than the diameter of the boss 31 so that the mating ring 4 can be in close contact with the boss 31. The rod body 11 sequentially passes through the adapter ring 4, the sealing part 3 and the gasket 2, so that the rod body can pass out. In the above technical solution, when the material 10 needs to be locked, the rod 11 is threaded through the material 10, and then the nut 20 is locked on the rod 11, and the material 10 may be formed by combining multiple layers of materials. When the gasket 2 is locked, the bolt 1 drives the matching ring 4 to downwards compress the protruding part 31, so that the sealing part 3 can compress the gasket 2. When water is on the bolt 1, the water flow drops downwards along the annular part 13, so that the water flow between the matching ring 4 and the sealing part 3 is reduced, and the water infiltration is reduced to be in contact with the rod body 11. Through above-mentioned technical scheme, can strengthen the bolt leakproofness, reduce the infiltration risk, increase of service life.
In this embodiment, the gasket 2 includes a base plate 21 and an annular protrusion 22, the annular protrusion 22 is located above the base plate 21, the annular protrusion 22 is disposed in a groove 321 of the base portion 32, the diameter of the base plate 21 is larger than that of the annular protrusion 22, and the material 10 can be dispersed by adopting a larger diameter base 21; further, the connection of the gasket 2 and the base portion 32 can be facilitated by the groove 321. The upper surface of the base portion 32 is provided with a tapered surface 322 so that water flow can be guided to the outside without accumulating on the surface.
In this embodiment, the surface of the end head 12 is provided with a mating groove 5, the mating groove 5 is provided with a plurality of grooves 6, the plurality of grooves 6 are arranged around the middle of the end head 12, and the mating groove 5 is used for being in butt joint with an external tool, so that the bolt can be conveniently screwed. By providing a plurality of grooves 6, the connection stability with an external tool can be improved. The groove 6 comprises an arc-shaped portion 61, a side edge portion 62 and a connecting portion 63, a first included angle m is formed between the side edge portion 62 and the connecting portion 63, the side edge portion 62 of the adjacent groove 6 is provided with a second included angle n, the arc-shaped portion 61 is located between the two connecting portions 63 of the groove 6, so that the contact area between the groove 6 and an external tool can be increased, the stability during screwing is improved, and the angle of the second included angle n is larger than that of the first included angle m.
