Detailed Description

Referring to fig. 1 to 4, an automatic lock catch includes a joint folding body 1, a joint folding hook 2, and a joint folding buckle 3, wherein the joint folding body 1 has a rod hole 11 penetrating up and down, and the joint folding body 1 has the joint folding hook 2 hinged and elastic thereto. The rod hole 11 is used for one of the two cross-hinged support rods 4 to pass through, and the front end of the folding joint buckle 3 is connected with the other support rod 5 of the two cross-hinged support rods. The front side of the joint hook 2 is provided with an accommodating groove 21, the rear end of the joint buckle 3 is provided with a clamping part 31, the clamping part 31 can push the joint hook 2 to rotate along with the gradual folding of the two cross hinged support rods, and the clamping part 31 can fall into the accommodating groove 21.

Referring to fig. 2 and 3, an extension portion 6 is disposed at the right end of the folding joint main body 1, a hinge groove 61 is disposed at the rear side of the extension portion 6, the left end of the folding joint hook 2 is located in the hinge groove 61 and is hinged to the extension portion 6, and a spring 7 abutting against the left end of the folding joint hook 2 is disposed in the hinge groove 61. More specifically, the left end of the folding joint hook 2 is provided with an upper hinged plate 22, a lower hinged plate 23 and a spring column 24, the spring column 24 is located between the upper hinged plate 22 and the lower hinged plate 23, the rear end of the spring 7 is sleeved outside the spring column 24, and the front end of the spring 7 is abutted against the inner end face of the hinged groove 61.

Referring to fig. 1 to 4, the right end of the foldable joint hook 2 is provided with a first inclined surface 25 inclined towards the left front, the rear end of the clamping portion 31 is provided with a second inclined surface 32 attached to the first inclined surface 25, and after the clamping portion 31 contacts the foldable joint hook 2, the clamping portion 31 moves along with the foldable joint buckle 3 under the cooperation of the first inclined surface 25 and the second inclined surface 32 to push and rotate the foldable joint hook 2 until the clamping portion 31 completely enters the accommodating groove 21, and then the foldable joint hook 2 is reset under the elastic force of the spring 7. The front end of the joint buckle 3 is provided with a rod groove 33, and the rod groove 33 is used for holding the support rod 5.

Referring to fig. 1 to 4, the design principle of the present invention is as follows: one of the two support rods 4 passes through the rod hole 11 and then is fixedly connected with the folding joint main body 1 through a double-headed rivet, and the other support rod 5 of the two support rods is positioned in the rod groove 33 and is fixedly connected with the folding joint buckle 3 through a double-headed rivet. When bracing piece 4 and bracing piece 5 are in the expansion state, the card portion of closing joint buckle 3 is in the non-cooperation state with the holding tank 21 of closing joint couple 2, when bracing piece 4 and bracing piece 5 will be folding, draw close gradually along with bracing piece 4 and bracing piece 5, it is inconsistent with closing joint couple 2 to close joint buckle 3's card portion 31, and close joint couple 2 promotion rotation with closing joint buckle 3's card portion 31 gradually along with folding, get into completely to close joint buckle 3's card portion 31 in the holding tank 21 of closing joint couple 2, it resets to close joint couple 2 this moment, it is located holding tank 21 and forms the connection of closing joint couple 2 and closing joint buckle 3 to close joint buckle 3's card portion 31, finally realize the fixed after cross-hinged bracing piece 4 and bracing piece 5 are folding. When the support rods 4 and 5 in the folded state are to be unfolded, the foldable joint hook 2 is pulled to rotate, and the clamping portion 31 of the foldable joint buckle 3 is separated from the accommodating groove 21 of the foldable joint hook 2.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
