There are some disadvantages in practical application. After long-term use, the connection accuracy between the latch and the traction component may decrease due to wear or deformation, affecting the traction effect and positioning accuracy. In addition, the latch connection operation requires manual connection and disconnection of the latch, which has certain requirements on the skill level of the operator and may have the risk of operating errors. It is also easy to cause jamming during operation. Utility Model Content

[0021] The present invention is described in detail below through specific embodiments, but the protection scope of the present invention is not limited thereto.

[0022] Example 1

[0023] This embodiment provides a new type of traction mechanism, such as Figure 3The traction mechanism shown is composed of a traction frame and a traction rotating mechanism. The traction frame and the base a11 are located on the trolley a1, and the traction rotating mechanism and the base b21 are located on the trolley b2; Fig. 9 As shown, the traction frame includes a bolt assembly a13, a bent plate 111, a traction rod 121, and a special-shaped plate 122; the traction rotation mechanism includes a bolt assembly b23, a U-shaped groove plate 211, a kit a212, a locking piece 221, a baffle plate 222, and a kit b223; wherein the traction rod 121 is fixedly connected to the special-shaped plate 122, and the special-shaped plate 122 is rotationally connected to the bent plate 111 through the bolt assembly a13; wherein one end of the locking piece 221 is fixedly connected to the baffle plate 222, and the other end of the locking piece 221 extends from the upper hole of the U-shaped groove plate 211 into the lower hole of the U-shaped groove plate 211 under the action of gravity, the baffle plate 222 is fixedly connected to the kit b223, the U-shaped groove plate 211 is fixedly connected to the kit a212, and the kit a212 and the kit b223 are rotationally connected around the bolt assembly b23.

[0024] The traction assembly 12 is formed by welding a special-shaped plate 122 and a traction rod 121; Figure 8 As shown, the traction rotation mechanism has a locking assembly 22 which is welded by a locking piece 221, a kit b223, and a baffle 222, and a fixing assembly which is welded by a U-shaped groove plate 211, a kit a212, and a bolt assembly b23.

[0025] like Figure 7 As shown, the traction rod 121 is divided into two parts, namely, an outer part and a welding part, wherein the outer part is integrally formed, specifically, it is composed of a semicircular arc, two ordinary cylinders, two inclined cylinders and two vertical cylinders; the two ordinary cylinders are arranged in parallel, and one end of the two ordinary cylinders is connected to the two ends of the semicircular arc; one end of the two inclined cylinders is connected to the two ordinary cylinders, and the other end of the two inclined cylinders is connected to the two vertical cylinders; the two vertical cylinders are arranged in parallel, and the distance between the two vertical cylinders is greater than that of the two ordinary cylinders, and the other ends of the two vertical cylinders are connected to the special-shaped plate 122; wherein the welding part is composed of a horizontal cylinder, and the two ends of the horizontal cylinder are respectively welded to the two ordinary cylinders of the outer part, and the horizontal cylinder is perpendicular to the two ordinary cylinders.

[0026] When trolley a and trolley b need to be towed, it is only necessary to lift the towing assembly 12 of trolley a upwards, and then rotate 90° clockwise with the bolt assembly a13 as the axis. At this time, the special-shaped plate 122 contacts the bent plate 111, and the towing assembly 12 is in a horizontal position. Figure 2 As shown, the mobile trolley a makes the traction assembly 12 face the U-shaped groove plate 211 in the traction rotating mechanism. Figure 4As shown, after the traction rod 121 contacts the traction rotating mechanism, the trolley a is moved to the position where the locking assembly 22 of the traction rotating mechanism rotates 45° clockwise with the bolt assembly b23 as the axis. The locking assembly 22 of the traction rotating mechanism will automatically rotate 45° with the bolt assembly b23 as the axis under the influence of gravity, and the locking member 221 will automatically pass through the traction rod 121 and be stuck in the lower end hole of the U-shaped groove plate 211 to achieve self-locking. At this time, the trolley a and the trolley b are in the traction state as shown in FIG. Figure 5 shown.

[0027] When trolley a and trolley b do not need to be towed, it is only necessary to turn the baffle 222 of the rotating mechanism to rotate the locking assembly 22 counterclockwise by 45°, and then move trolley a or trolley b to separate the two. After the towing assembly 12 is rotated counterclockwise by 90° with the bolt assembly a13 as the axis, the towing assembly 12 will automatically fall into the curved plate 111 under the influence of gravity. At this time, trolley a and trolley b are restored as Figure 1 Status shown.

[0028] A method for using a new type of traction mechanism, the steps of use are as follows:

[0029] S1, move the traction assembly 12, align the traction assembly 12 with the notch of the U-shaped groove plate 211 and insert it into the U-shaped groove plate 211;

[0030] S2. During the insertion of the traction component 12 into the U-shaped groove plate 211, the traction component 12 pushes the locking component 22 to rotate with the bolt component b23 as the axis; when the traction component 12 slides over the bottom end of the locking component 22, the locking component 22 is reset under the influence of gravity, so that the locking member 221 is inserted into the hole on the lower end surface of the U-shaped groove plate 211, thereby locking the traction frame and the traction rotating mechanism; at this time, the traction component 12 is in a locked state;

[0031] S3. When traction is not needed, the traction assembly 12 is further inserted into the U-shaped groove plate 211, and the baffle 222 of the locking assembly 22 is moved to make the locking assembly 22 rotate in the reverse direction along the original path, thereby releasing the lock between the traction frame and the traction rotating mechanism;

[0032] S4, then move the traction assembly 12 to make the traction assembly 12 leave the U-shaped groove plate 211 of the traction rotation mechanism;

[0033] S5. Rotate the traction assembly 12 with the bolt assembly a13 as the axis, so that the traction assembly 12 rotates 90° relative to the locked state of the traction assembly 12. The traction assembly 12 automatically falls to a vertical state under the influence of gravity.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention, but not all feasible embodiments of the present invention. For those skilled in the art, any obvious changes made to the present invention without departing from the principle and spirit of the present invention should be considered to be included in the scope of protection of the claims of the present invention.
