Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1 to 5, there is shown a bolt assembly for a grill according to the present invention, including:
the T-shaped bolt 1 is characterized in that the tail 11 of the T-shaped bolt 1 is provided with external threads 11a, the head 12 of the T-shaped bolt 1 is provided with a threaded hole 12a, and the radius of the head 12 of the T-shaped bolt 1 is larger than that of the tail 11 of the T-shaped bolt 1;
a locking nut 2, wherein the locking nut 2 is installed at the tail 11 of the T-shaped bolt 1 in a threaded mode;
the gasket 3 sequentially comprises a first circular ring 31, a first annular circular arc 32 extending obliquely upwards along the outer edge of the first circular ring 31, a second circular ring 33 extending horizontally outwards along the outer edge of the first annular circular arc 32 and a second annular circular arc 34 extending obliquely downwards along the outer edge of the second circular ring 33 from inside to outside, and a circular hole 31a is formed in the center of the first circular ring 31; and
and a screw 4, wherein the tail part 41 of the screw 4 passes through the round hole 31a of the first ring 31 of the washer 3 and is screwed in the threaded hole 12a of the head part 12 of the T-shaped bolt 1, and the head part 42 of the screw 4 is tightly attached to the washer 3.
The bolt assembly for the grating further comprises a cushion block 5, the cushion block 5 is installed at the tail part 11 of the T-shaped bolt 1, and the cushion block 5 is tightly attached to one surface, close to the washer 3, of the locking nut 2.
A through hole 21 is axially formed in the end face of the locking nut 2, a locking wire 22 is arranged in the through hole 21, and one end of the locking wire 22 penetrates through the through hole 21 of the locking nut 2 and is bent inwards to be attached to one end face of the locking nut 2.
The utility model discloses mainly play the effect of fixed grid, when using, 3 cards of packing ring are established on a terminal surface of grid (not shown in the figure), and the afterbody 11 of T type bolt 1 passes the grid, and another terminal surface of grid is hugged closely to the one end of cushion block 5, and lock nut 2 screws this moment, and lock nut 2 is hugged closely to the other end of cushion block 5, and the afterbody 11 of wearing out lock nut 2 of T type bolt is hugged closely to lock silk 22.
The utility model has simple structure, convenient production and convenient use; the design of the washer 3 ensures that the coverage area is large, the design of the first circular ring 31, the first circular arc 32, the second circular ring 33 and the second circular arc 34 ensures enough supporting strength, the locking wire 22 prevents the locking nut 2 from loosening after locking, and if the locking nut 2 loosens, the locking wire 22 provides large friction force to prevent the locking nut 2 from rotating when rotating; because the terminal surface is not level and smooth enough under the grid normal conditions, the setting of cushion block 5 is more convenient for install, promotes the laminating degree with the grid, the utility model discloses can satisfy the demand of the grid of different models, can realize with a set of bolt assembly adaptation for the grid in multiple grid, the practicality is higher, and economic nature is good.
