## Abstract

A buckle locking structure device for a rear compartment cover of a pickup truck includes: a cross rod aluminum extrusion (1); a slider (2); a T-rod (3); a buckle block (4); a handle (5); a T-insertion block (7); and a frame body aluminum extrusion (8); a lug (403) provided center of a bottom surface of the buckle block (4); left and right semi-circular arc flanges (4031) provided on the center of the bottom surface of the buckle block (4) on a and to left and right sides of the lug (403), respectively; a left edge part slot (5031) extending towards lug (403) and being engageable with the left semi-circular arc flange (4031) of the buckle block (4) so that the left edge part slot (5031) slides on the left semi-circular arc flange (4031) of the buckle block (4) for fastening.

## Claims

### Claim 1

A buckle locking structure device for a rear compartment cover of a pickup truck, includes:
a cross rod aluminum extrusion (1), a slider (2), a T-rod (3), a buckle block (4), a handle (5), a T-insertion block (7), and a frame body aluminum extrusion (8),
wherein the buckle block (4) is a rectangular block,
wherein a buckle slot (401) is provided on the buckle block (4),
wherein a cylinder (406) is provided on a center of a top surface of the buckle slot (401),
wherein a first through hole is provided in a center of the cylinder (406),
wherein the cross rod aluminum extrusion (1) is in a hollow strip shape, wherein a channel (101) is provided in a center of the cross rod aluminum extrusion (1),
wherein the slider (2) is a rectangular hollow block, wherein a slide hole channel (203) is provided in an upper part of a center of the slider, wherein the slide hole channel (203) is fittable over the cross rod aluminum extrusion (1) so that the slider can move back and forth quickly on the cross rod aluminum extrusion (1),
wherein a vertical U-shaped channel (201) and a transverse U-shaped channel (202) are provided in a lower part of the center of the slider, wherein the vertical U-shaped channel and the transverse U-shaped channel are crossed each other,
wherein a lug (403) is provided on a center of a bottom surface of the buckle block (4),
wherein left and right semi-circular arc flanges (4031) are provided on the center of the bottom surface of the buckle block (4) and to left and right sides of the lug (403), respectively,
wherein a left groove face (504) is provided on a lower inner side wall of the buckle block (4),
wherein a right groove face (504) is provided on the lower inner side wall of the buckle block (4),
wherein a left edge part slot (5031) extends from the left groove face (504) towards lug (403) and is engageable with the left semi-circular arc flange (4031) of the buckle block (4) so that the left edge part slot (5031) slides on the left semi-circular arc flange (4031) of the buckle block (4) for fastening,
wherein the right edge part slot (5031) extends from the right groove face (504) towards lug (403) and is engageable with the right semi-circular arc flange (4031) of the buckle block so that the right edge part slot (5031) slides on the right semi-circular arc flange (4031) of the buckle block (4) for fastening.
