DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] To enable a further understanding of the present invention content of the invention herein, refer to the detailed description of the invention and the accompanying drawings below:

[0017] As shown in FIG. 1 to FIG. 4, the portable barbecue oven comprises an oven body 1, a net 2 horizontally provided in the oven body 1, a grill 3 spanned above the net 2, a scissor-shaped frame 4 movably attached to the oven body 1 and two folding mechanisms 5.

[0018] The scissor-shaped frame 4 has a first bracket 41 and a second bracket 42, each of the first bracket 41 and the second bracket 42 has a top end and a bottom end, the first bracket 41 is pivoted to the second bracket 42, the top end of the first bracket 41 and the top end of the second bracket 42 are respectively movably attached to the side wall of the oven body 1. In this embodiment, the detail is, the first bracket 41 includes a pair of a first side rod 43 and a second side rod 44 disposed opposite of each other and each having a top end and a bottom end; the second bracket 42 includes a pair of a third side rod 43′ and a fourth side rod 44′ disposed opposite of each other and each having a top end and a bottom end; and a shaft lever 45 is connected between bottom ends of the first side rod 43 and the second side rod 44; the first side rod 43 of the first bracket 41 is movably connected to the third side rod 43′ of the second bracket 42 to form a X shape, and the second side rod 44 of the first bracket 41 is movably connected to the fourth side rod 44′ of the second bracket 42 to also form another X shape ; the top ends of the first side rod 43 and the second side rod 44 are respectively pivoted to the oven body 1 through the folding mechanism 5; two guiding wheels 47 are disposed respectively at two ends of the shaft lever 45 of the first bracket 41; and a hand grab 46 is connected between bottom ends of the third side rod 43′ and the fourth side rod 44′ of the second bracket 42. In this way, when the barbecue oven is in the folded state, the hand grab 46 can be held and lifted upward, then the barbecue oven can be moved through the guiding wheels 47.

[0019] Further, each folding mechanism 5 comprises a connection member 52 and an adjustment piece 51, the adjustment piece 51 has a slot 53 for the connection member 52 to pass through. In this embodiment, the adjustment piece 51 is square, with part of the top end thereof being extended upward to form a mounting portion. The mounting portion has a plurality of mounting holes through which bolts are penetrated to fixedly connect the adjustment piece 51 to the side walls of the oven body 1. Correspondingly, the connection member 52 is a bolt attached to the top end of the first bracket 41, the first side rod 43 and the second side rod 44 of the first bracket 41 has a through hole 9 at the top end thereof, the connection member 52 passes through the slot 53 and the through hole 9 to movably connected the first bracket 41 to the adjustment piece 51.

[0020] To make the connection between the adjustment piece 51 and the first bracket 41 more firm, a position locking hole 531 for positioning the connection member 52 is connected to the slot 53. To make the internal structure of the scissor-shaped frame 4 more firm, a reinforcement plate 6 is respectively connected between the first side rod 43 and the second side rod 44 of each of the first bracket 41 and between the third side rod 43′ and the fourth side rod 44′ of the second bracket 42, at the position close to a pivoting point of the first bracket 41 and the second bracket 42. To avoid relative displacement between the scissor-shaped frame 4 and the oven body 1 and between the first bracket 41 and the second bracket 42 when in the folded state, in this embodiment, the side walls of the frame 4 and the side walls of the oven body 1 are detachably connected by a detachable snap structure. In detail, a hook 7 is provided on a rear side wall of the oven body 1, and a snap 8 hooked onto the hook 7 is provided on a rear outer side of the frame 4.

[0021] The barbecue oven in this embodiment is unfolded in such a way: hold the hand grab 46 on the second bracket 42 and press downward it; lift the second bracket 42 up and transfer the force to the first bracket 41; the guiding wheels 47 on the first bracket 41 is rolled inward so that the connection member 52 on the first bracket 42 slides toward the inner side of the barbecue oven along the slot 53; when the scissor-shaped frame 4 is completely unfolded, clamp the connection member 52 into the position locking hole 531, and now screw the connection member 52 (i.e., the bolt) to tightly connect the adjustment piece 51 to the scissor-shaped frame 4, so that the scissor-shaped frame 4 supports the oven body 1 firmly.

[0022] The barbecue oven in this embodiment is folded in such a way: release the connection member 52 and move out from the position locking hole 531, the guiding wheel 47 on the first bracket 41 is rolled outward, the connection member 52 slides to the outer side of the barbecue oven along the slot 53, and the included angle between the first bracket 41 and the second bracket 42 is gradually reduced until they are overlapped with each other. Now, the scissor-shaped frame 4 is completely folded. Finally, on the back of the barbecue oven, connect the snap 8 on the rear outer side wall of the scissor-shaped frame 4 to the hook 7 on the rear outer side wall of the oven body 1. In this way, the barbecue oven is folded.
