Detailed Description

Referring to fig. 1 to 4, the present invention provides a fastener, including a clamping plate 1 formed by an upper plate 11, a side plate 12, and a lower plate 13 connected in sequence, further including a screw 3 and an elastic gasket 2, the lower plate 13 has a threaded hole matched with the screw 3, the left and right sides of the elastic gasket 2 are bent downward and then bent toward the middle of the elastic gasket 2 horizontally to form a reverse buckle 21, the bottom surface of the elastic gasket 2 has a front and a rear bulges 22, the bulges 22 are located between the two reverse buckles 21, and the periphery of the end of a screw 31 of the screw 3 is provided with a boss 32; the elastic gasket 2 deforms when pressed, the tail end of the screw 31 falls between the two protrusions 22, the peripheral edge of the boss 32 abuts against the two protrusions 22, and then the elastic gasket 2 resets and the reverse buckle 21 fastens the boss 32. The elastic gasket 2 and the clamping plate 1 are integrally formed. The protrusions 22 are formed by stamping the elastic pad 2, wherein the top surface of the elastic pad 2 is recessed and the bottom surface of the elastic pad 2 is formed with the protrusions 22.

The utility model discloses still ask to protect a lamps and lanterns, including this fastener, still include light source, lamp body 4, light-permeable cover 5; the light source is arranged in the lamp shell 4, and the light-transmitting cover 5 and the lamp shell 4 are matched to seal the light source; the end of the screw 31 passes through the threaded hole and the elastic gasket 2 is pressed to fasten the boss 32, the clamping plate 1 clamps the bottom of the shell edge 41 of the lamp housing 4 and the top surface of the light-transmitting cover 5, and after the screw 3 is screwed with the threaded hole, the top surface of the elastic gasket 2 abuts against the bottom surface of the shell edge 41 to fixedly connect the light-transmitting cover 5 and the lamp housing 4.

The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto, and any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are equivalent replacement modes, and are all included in the scope of the present invention.
