Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 3, the folding fork includes:

the installation frame 100 is a rectangular frame structure enclosed by an upper cross beam 110, a lower cross beam 120, a left vertical plate 130 and a right vertical plate 140, and a suspension column 150 is transversely and fixedly arranged between the left vertical plate 130 and the right vertical plate 140;

the pallet fork main body 200 comprises a vertical fork body 210 and a horizontal fork body 220, the vertical fork body 210 and the horizontal fork body 220 are integrally arranged into an L shape, the upper end of the vertical fork body 210 is welded with a suspension lug 230, and the suspension lug 230 penetrates through the suspension column 150 and is rotatably connected with the suspension column 150;

a hook 300 including a horizontal portion 310 attached to the top surface of the upper beam 110, and a support portion 320 vertically extending forward along one end of the horizontal portion 310, wherein the other end of the horizontal portion 310 opposite to the support portion 320 is detachably connected to the upper beam 110 by a fastening screw 400;

when the fork main body 200 is unfolded, the lower end of the vertical fork body 210 abuts against the lower cross beam 120, and the hook 300 is folded above the upper cross beam 110;

when the fork main body 200 is folded, the fork main body 200 is rotated upward along the hanging column 150, and the hook 300 is rotated to the front side of the mounting frame 100 and makes the support 320 abut against the vertical fork body 210 upward.

By providing the hook 300 capable of horizontally rotating on the upper cross beam 110 of the mounting frame 100, after the fork main body 200 is folded upwards, the fork main body 200 can be supported and fixed by using the support portion 320 of the hook 300, when the fork main body 200 needs to be unfolded to carry a cargo, the fork main body 200 is lifted, the fastening screw 400 is loosened, the hook 300 is rotated above the upper cross beam 120 to fold the hook 300, and then the fork main body 200 can be turned downwards under the action of gravity until the lower cross beam 120 abuts against the fork main body 200 to limit the rotation of the fork main body 200, at this time, the fork main body 200 can be used for carrying work. In the folding fork, the fork main body 200 is of an integrated structure, so that the carrying capacity is strong, the folding operation is simple and convenient, and the folding fork is practical and reliable.

In this application, the number of fork main part 200 is two, and two fork main parts 200 symmetrical arrangement have a couple 300 in the left and right sides of installation frame 100, and every fork main part 200 corresponds to be arranged.

Wherein, fastening screw 400 is the preferred hand wheel screw, and fork main part 200 folding in-process all need not the instrument supplementary in the whole journey promptly, can realize the fixed of couple through manual operation, and it is all more convenient that fork main part 200 expandes or folds. Preferably, the hook 300 is integrally U-shaped to improve the bending resistance and load-bearing capacity of the hook 300.

A middle cross beam 160 is fixedly arranged between a left vertical plate 130 and a right vertical plate 140 of the mounting frame 100, a middle vertical plate 170 is fixedly arranged between an upper cross beam 110 and a lower cross beam 120, the suspension columns 150 are located above the middle cross beam 160, and suspension lugs 230 of the two fork main bodies 200 are respectively located between the middle vertical plate 170 and the left vertical plate 130 and between the middle vertical plate 170 and the right vertical plate 140.

The middle riser 170 may also serve to limit the range of motion of the fork bodies 200 by providing the middle cross member 160 and the middle riser 170 in the mounting frame 100 to improve the structural strength of the mounting frame 100, facilitating adjustment of the spacing between the two fork bodies 200.

It is worth mentioning that after being folded upwards, the fork main body 200 is limited between the hook 300 and the left vertical plate 130 or between the hook 300 and the right vertical plate 140, so that the fork main body 200 is prevented from shaking left and right in the transportation process, and the fork main body 200 is more firmly fixed after being folded, and the safety is better.

In this application, the suspension lug 230 is protruding to be formed with stopper 231 backward, between well riser 170 and left riser 130, set firmly limiting plate 500 respectively between well riser 170 and the right riser 140, two limiting plate 500 are located well crossbeam 160 top, upwards offer three spacing groove 510 that supply the embedding of stopper along limiting plate 500 lower limb, three spacing groove 510 along the horizontal direction equipartition.

When the fork main body 200 is unfolded, the limiting part 231 of the hanging lug 230 is embedded into one of the limiting grooves 510, and at this time, the fork main body 200 cannot slide left and right randomly, i.e., the distance between the two fork main bodies 200 is relatively fixed, so that the use is reliable. When the position of the fork main body 200 needs to be adjusted to accommodate goods of different sizes, the fork main body 200 is turned up so that the position-limiting portions 231 of the suspension lugs 230 are disengaged from the position-limiting grooves 510, the fork main body 200 is slid left and right, and then the fork main body 200 is turned down so that the position-limiting portions 231 are engaged with the other position-limiting grooves 510. Namely, the spacing between the two fork main bodies 200 can be adjusted and locked by the cooperation of the limiting part 231 and the limiting groove 510, and the operation is convenient and the use is reliable.

In order to make the fork main body 200 more stable when overturning, each fork main body 200 is symmetrically provided with two suspension lugs 230 on the left and right sides, and only one suspension lug 230 of the two suspension lugs 230 of each fork main body 200 is provided with a limiting part 231, so as to avoid obstructing the position adjustment of the fork main body 200.

In this application, the rear side of vertical fork 210 has welded cushion 240, and cushion 240 and bottom end rail 120 butt to it is more even to make bottom end rail 120 atress.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
