[0028] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0029] Please combine Figure 1 - Figure 4 A forward and reverse loading fork of this embodiment includes a fork body 2 and a fork frame 1. In order to facilitate the installation of the fork body 2, a hook 3 is first fixed to one side of the fork body 2 by welding. The hook 3 is provided with two hooks, namely an upper hook 31 and a lower hook 32, which have the same structure. The one close to the bending part of the fork body 2 is defined as the lower hook 32, and the other is defined as the upper hook 31.

[0030] A through fixing hole 33 is provided in the middle of the hook 3, and an internal thread can be provided in the fixing hole 33, and a fixing screw 4 is connected through the thread. In addition, a plurality of slots 8 are provided on the fork frame 1, and the hook 3 can be connected to the fork frame 1, and the fixing screw 4 can be rotated to make the lower end of the fixing screw 4 extend into the slot 8, thereby fixing the fork body 2.

[0031] Because only the upper end of the fork frame 1 is provided with a slot 8, the corresponding hook 3 can be fixed by the fixing screw 4. In order to further fix the fork body 2 and prevent it from shaking, a positioning hole 5 is also provided on the fork frame 1. The positioning hole 5 is an oblong hole. In addition, a positioning plate 6 is also provided. Two positioning rods 7 are fixedly connected to the positioning plate 6. When in use, the two positioning rods 7 are respectively located on both sides of the fork body 2 and pass through the positioning hole 5. A thread can be provided at the end of the positioning rod 7, and a nut can be provided. After the positioning rod 7 passes through the positioning hole 5, it is connected to the nut. In this way, the lower end of the fork body 2 is fixed to the fork frame 1 to prevent it from shaking.

[0032] When the fork body 2 needs to be used in reverse, the nuts on the fixing screw rod 4 and the positioning rod 7 are removed. The fork body 2 is reversed, so two upper hooks 31 and lower hooks 32 with the same structure in opposite directions are provided at the same time, so after the fork body 2 is reversed, it can still be installed and fixed in the same way.

[0033] The fork body 2 is installed in reverse, mainly for hoisting some goods. In order to facilitate hoisting, a mounting box 9 is also provided, and a hole is provided in the middle of the mounting box 9 for the fork body 2 to pass through, and the fork body 2 can directly pass through the mounting box 9. In order to fix the mounting box 9 and the fork body 2 together and prevent the mounting box 9 from slipping when hoisting goods, a fixing clamp 10 is also provided on the mounting box 9, and the fixing clamp 10 is used to fix the mounting box 9 and the fork body 2 together.

[0034] Specifically, a through hole is provided at the top of the installation box 9, wherein the lower end of the fixing clamp plate 10 is located inside the installation box 9, and the upper end thereof protrudes from the installation box 9. In addition, a rotating drum 12 is connected to the fixing frame plate located outside the installation box 9, and an internal thread is provided inside the rotating drum 12. To match this, a threaded rod 11 is also rotatably installed at the top of the installation box 9, and the threaded rod 11 passes through the rotating drum 12. When the threaded rod 11 is controlled to rotate, the fixing clamp plate 10 can be driven to move up and down along the direction of the threaded rod 11.

[0035] Therefore, in the initial state, the fixed clamping plate 10 is at the lowest point, and the fork body 2 can pass through the installation box 9 and the fixed clamping plate 10 from the middle, and then the threaded rod 11 is rotated to drive the fixed clamping plate 10 to move upward, and finally the fork body 2 will be clamped and fixed in the middle with the installation box 9. This prevents the installation box 9 from slipping during lifting, causing the goods to shake or even greater danger.

[0036] In order to facilitate hoisting, an adjustment rail 13 is welded and fixed at the bottom of the installation box 9 , and a chuck 15 is clamped in the adjustment rail 13 . The chuck 15 is clamped in the adjustment rail 13 and can move in the adjustment rail 13 .

[0037] A lifting lock 14 is fixedly connected below the chuck 15, and a thread is provided at the lock rod (not marked in the figure) of the lifting lock 14, and a fixed lock cap 16 is connected to the outside of the lifting lock 14 through a thread. That is, the lifting lock 14 can move along the adjustment track 13 together with the chuck 15 to adjust the position of the lifting lock 14. In this embodiment, four lifting locks 14 are provided, which is convenient for cooperating with each other to lift some objects with special structures. For example, for a long-sized main body, multiple lifting locks 14 are easier to maintain balance than a single lifting lock 14.

[0038] The implementation process and principle of a forward and reverse loading fork in the embodiment of the present application are as follows:

[0039] Therefore, two hooks 3 with the same structure and in opposite directions are fixedly connected to the fork body 2, namely, the upper hook 31 and the lower hook 32, so that the fork body 2 can still be installed and fixed in the same way after being reversed. That is, above the fork frame 1, the fork body 2 is positioned and fixed by the fixing screw 4, and below the fork frame 1, the fork body 2 can be fixed by the cooperation of the positioning plate 6, the positioning rod 7 and the nut to prevent shaking and ensure stability when lifting fork cargo.

[0040] In addition, when the fork body 2 is reversely installed, the threaded rod 11 can be rotated to drive the fixed frame plate to move upward, and cooperate with the inner wall of the installation box 9 to fix the fork body 2, which can prevent the installation box 9 from slipping during lifting;

[0041] In addition, the fixed lock cap 16 is rotated to make the fixed lock cap 16 and the lower surface of the installation box 9 out of contact. At this time, it is convenient to adjust the position of the lifting lock 14. The lifting lock 14 and the chuck 15 can move along the adjustment track 13. For goods of different shapes and volumes, the corresponding number of lifting locks 14 are selected and moved to the specified position. The fixed lock cap 16 is rotated in the opposite direction, and the fixed lock cap 16 and the bottom surface of the installation box 9 are tightly fitted. Thus, the lifting lock 14 is fixed.

[0042] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
