[0020] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] In the description of the utility model, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the viewing direction or position relationship, and are only for the convenience of describing the utility model, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0022] In addition, for the convenience of description, in this application, the direction of the length of the upper locking hook hole slot and the lower locking hook hole slot is defined as the front-to-back direction, that is, the Y direction. Figure 1 The up-down direction is the Z direction, and the direction where the pin 9 is located is the X direction.

[0023] like Figure 1-Figure 3 The material rack traction device shown in the figure includes an upper traction plate 1, a lower traction plate 2, a connecting plate, a fixing plate 5, a locking hook 10 and a rotating component. The upper traction plate 1 and the lower traction plate 2 are both provided with locking hook hole grooves. The front end of the locking hook 10 is rotatably connected to the upper part of the upper traction plate 1 through a rotating component, and the rear end passes downward through the lower part of the lower traction plate 2. The rear end of the locking hook 10 can be driven by the rotating component to rotate upward to a position between the upper traction plate 1 and the lower traction plate 2.

[0024] Specifically, the upper traction plate 1 is located directly above the lower traction plate 2, the lengths of the two are distributed along the front-to-back direction and both are distributed horizontally, the upper traction plate 1 and the lower traction plate 2 are respectively provided with an upper locking hook hole groove 6 and a lower locking hook hole groove 7, the upper locking hook hole groove 6 is located directly above the lower locking hook hole groove 7, both penetrate their respective plate thicknesses and are distributed along the front-to-back direction.

[0025] A fixing plate 5 is welded at the rear end between the upper traction plate 1 and the lower traction plate 2, and a first connecting plate 3 and a second connecting plate 4 are welded at the left and right sides between the upper traction plate 1 and the lower traction plate 2, respectively.

[0026] The rotating component is arranged at the front end above the upper traction plate 1 and is located in front of the upper locking hook hole groove 6 and the lower locking hook hole groove 7. The rotating component is composed of two groups of sleeves 8 and a group of pins 9. The two groups of sleeves 8 are symmetrically distributed along the upper locking hook hole groove 6. The sleeves 8 are welded and fixed to the upper end surface of the upper traction plate 1 and the length is distributed along the left and right directions. The length of the pin 9 is horizontally distributed along the left and right directions. The left and right ends of the pin 9 are located inside the left and right groups of sleeves 8 and are rotatably connected to the sleeves 8. The outer diameter of the pin 9 is smaller than the outer diameter of the sleeve 8. A rotating part with an annular groove is formed between the pin 9 and the sleeve 8.

[0027] The front end of the lock hook 10 passes through the upper lock hook hole groove 6 upward, and the bent portion of the lock hook 10 overlaps the pin shaft 9. The lower end is tilted downward from front to back and passes through the lower lock hook hole groove 7 and is located below the lower traction plate 2.

[0028] The length between the front end bending part of the lock hook 10 and the rotation point of the pin 9 to the rear end of the lock hook 10 is the rotation radius R of the lock hook 10, the distance between the front end bending part of the lock hook 10 and the rotation point of the pin 9 to the rear end of the lower lock hook hole groove 7 is L1, and the distance between the front end bending part of the lock hook 10 and the rotation point of the pin 9 to the rear end of the upper lock hook hole groove 6 is L2. It is limited that L2<R<L1. Through this limited condition, when the upper end of the lock hook 10 is rotated along the YZ plane through the pin 9 under the action of external force, the lower end of the lock hook 10 can be rotated upward to between the upper traction plate 1 and the lower traction plate 2, but cannot continue to rotate upward to above the upper traction plate 1, and when the lock hook 10 is not subject to external force, its lower end passes through the lower lock hook hole groove 7 and falls into the position below the lower traction plate 2.

[0029] In this embodiment, the lengths of the upper lock hook hole slot 6 and the lower lock hook hole slot 7 in the front-to-back direction or in the Y direction are the same. Since the length from the rotation point of the lock hook 10 to the lower end of the lock hook 10 is an arc when rotating, under the condition that the lengths of the upper lock hook hole slot 6 and the lower lock hook hole slot 7 are the same, it is only necessary to ensure the precondition of L1<R to satisfy the above-mentioned limiting condition of L2<R<L1.

[0030] When the device is in use, when the traction hook and the traction seat are connected, press the upper end of the lock hook 10 with your fingers, the pin shaft 9 rotates in the shaft sleeve 8 to drive the lower end of the lock hook 10 to lift up, and then put the ring of the traction hook into the middle of the upper and lower traction plates, release the lock hook 10 with your fingers, and the lock hook 10 fixes the traction hook ring between the two traction plates under the action of its own gravity, thereby completing the connection between the traction hook and the traction seat.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
