[0018] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0019] See also Figures 1 to 3 , which is a structural schematic diagram of a material cart traction structure provided by the utility model. The material cart traction structure includes at least one buckle structure 10 arranged on one side of the chassis of the material cart, and at least one locking and separation device 20 arranged on one side of the chassis of the same material cart relative to the buckle structure 10. It can be imagined that the material cart traction structure also includes some other functional modules, such as connectors, etc., which are well known to those skilled in the art and will not be described in detail here.

[0020] First of all, it should be noted that the traction structure of the material cart is arranged on the chassis of the material cart. The material cart and the chassis of the material cart should be existing technologies and will not be described in detail here.

[0021] The buckle structure 10 includes at least one traction rod 11 arranged on the material vehicle, at least one rotation axis 12 as the rotation center of the traction rod 11, and at least one support structure 13 arranged on the material vehicle. On the adjacent material vehicle, the buckle structure 10 is fixedly connected to the locking and separating device 20. The buckle structure 10 and the locking and separating device 20 are arranged at the same height on the material vehicle, so that the traction rod 11 can be pushed into the fixed frame 21.

[0022] The shape of the traction rod 11 is U-shaped, which is convenient for quickly installing the traction rod 11 in the locking and separating device 20. It is conceivable that, according to actual application requirements, the shape of the traction rod 11 can be designed into other shapes such as a rectangle. The traction rod 11 is used to buckle on the locking and separating device 20 of the corresponding material vehicle to achieve simultaneous connection and movement of multiple material vehicles. The traction rod 11 is provided with a cross bar 111 perpendicular to the arrangement direction of the buckle structure 10 and the locking and separating device 20, so that the cross bar 111 connects the opening of the traction rod 11 to form a closed space to lock the locking and separating device 20, while maintaining an appropriate distance between adjacent material vehicles to avoid collisions due to inertia when the material vehicles are transported or stopped.

[0023] The rotating shaft 12 is arranged on the material vehicle near the traction rod 11. The rotating shaft 12 is perpendicular to the arrangement direction of the buckle structure 10 and the locking and separating device 20, so that the rotation direction of the traction rod 11 is toward the locking and separating device 20 to be connected. The traction rod 11 is arranged on the rotating shaft 12, and the rotating shaft 12 is used to adjust the position of the traction rod 11. When the material vehicle is connected, the traction rod 11 is at the same height as the locking and separating device 20 in the material vehicle to be connected, and the traction rod 11 is pushed to slide into the locking and separating device 20; when the material vehicle is separated, the traction rod 11 that is separated from the rotating and separating device 20 is rotated and placed in the material vehicle where it is located.

[0024] The support structure 13 includes at least one support plate 131 arranged on the periphery of the traction rod 11, and at least one support rod 132 arranged on the material vehicle. The support structure 13 is used to increase the maximum height of the traction rod 11 when it is in the material vehicle, so that the user can operate the traction rod 11 without bending over, thereby improving the safety and efficiency of the user during operation. The support plate 131 is arranged on the traction rod 11, and is used to provide a fulcrum for the support rod 132 to support the traction rod 11. In this embodiment, the support plate 131 is arranged on the traction rod 11 near one end of the rotating shaft 12, that is, by increasing the angle between the traction rod 11 and the material vehicle, the maximum height of the traction rod 11 when it is in the material vehicle is increased, so that the user can operate the traction rod 11 conveniently. When the material vehicle starts to connect with the vehicle, the traction rod 11 is pushed away from the support rod 132, so that the traction rod 11 stops in a direction parallel to the plane where the moving track of the material vehicle is located under the action of gravity.

[0025] The locking and separation device 20 includes at least one fixed frame 21 arranged on the other side relative to the buckle structure 10, at least two slide grooves 22 arranged opposite to each other on the fixed frame 21, at least one fixed wheel 23 arranged on the fixed frame 21, and at least one locking control structure 24 moving on the slide groove 22.

[0026] The fixed frame 21 includes an upper plane provided with the slide groove 22, a lower plane provided with another slide groove 22, and two side surfaces connecting the upper plane and the lower plane. The fixed frame 21 opens in the direction of the buckle structure 10 to be connected to the material vehicle. The fixed frame 21 is provided with an opening to facilitate the entry of the traction rod. In this embodiment, the opening direction of the fixed frame 21 is parallel to the arrangement direction of the material vehicle to be connected, so as to reduce the torque during movement, thereby improving the movement efficiency. It can be imagined that, according to the actual movement path of the material vehicle, the installation direction of the fixed frame 21 and the connected buckle structure 10 is inclined to the arrangement direction of the connected material vehicle. In this embodiment, a notch is provided near the opening of the side of the fixed frame 21, so that the area of ​​the side is reduced in the direction from the buckle structure 10 to the locking and separating device 20, so that the two sides of the opening of the fixed frame 21 have a larger space, thereby reserving space for the lateral rotation displacement of the traction rod 11, so as to facilitate the material vehicle to perform curved movements such as turning. The height of the lower plane is equal to the height at which the rotating shaft 12 is arranged on the material vehicle, so that the traction rod 11 can successfully enter the fixing frame 21 .

[0027] The slide grooves 22 are relatively arranged on the upper plane and the lower plane of the fixed frame 21, so that the control lock structure 24 can simultaneously insert a plurality of the slide grooves 22. The extension direction of the slide grooves 22 is perpendicular to the rotation axis 12, so that the slide grooves 22 are arranged on the installation path from the traction rod 11 to the fixed frame 21, thereby urging the control lock structure 24 to be inserted on the installation path from the traction rod 11 to the fixed frame 21. The slide grooves 22 are used to assist the control lock structure 24 in locking or separating the traction rod 11.

[0028] The fixing wheel 23 is arranged on the upper plane. The fixing wheel 23 is used to fix the control lock structure 24 to prevent the control lock structure 24 from falling off the locking and separating device 20, and to assist the control lock structure 24 in rotating in the slide groove 22. The setting of the fixing wheel 23 is related to the control lock structure 24 described below, and will be described in detail in conjunction with the control lock structure 24 described below.

[0029] The locking structure 24 is arranged on the fixed wheel 23 and located in the slide groove 22. The locking structure 24 includes a locking rod 241 inserted in one or more of the slide grooves 22, and a control rod 242 connected to the locking rod 241. The locking rod 241 is connected to the control rod 242 to form a folding rod. The connection between the locking rod 241 and the control rod 242 is arranged on the fixed wheel 23, and the connection is used as a rotation fulcrum. The control rod 242 is perpendicular to the fixed wheel 23, because the fixed wheel 23 is parallel to the rotation axis 12, so that the movement trajectory of the control rod 242 is parallel to the plane at the position of the plurality of slide grooves 22. The control rod 242 is arranged on the side of the rotation fulcrum opposite to the slide groove 22, so that when the control rod 242 is pressed, the locking rod 241 rotates in the slide groove 22. The control rod 242 is used to control the locking rod 241 to achieve locking and separation of the traction rod 11. In the natural state, the control rod 242 is fixed to the fixed frame 21 via the fixed wheel 23 under the influence of gravity, and the locking rod 241 is attached to the side of the slide slot 22 opening toward the fixed frame 21, and is vertically inserted into the two oppositely arranged slide slots 22. When the material cart is connected, the locking rod 241 is inserted into the traction rod 11 and is located on the movement trajectory of the traction rod 11 leaving the fixed frame 21 to prevent the traction rod 11 from leaving the fixed frame 21. The locking rod 241 receives a force from the traction rod 11, and the force is directed toward the opening direction of the fixed frame 21. The locking rod 241 also receives a supporting force from the sides of the multiple slide slots 22, and the direction of the supporting force is opposite to the direction of the force applied by the traction rod 11, thereby fixing the traction rod 11 in the fixed frame 21. When the material cart is separated, the control rod 242 controls the locking rod 241 to leave the traction rod 11. The control rod 242 moves toward the lower plane, so that the locking rod 241 leaves the sliding groove 22 located on the lower plane.

[0030] When in use, the traction rod 11 is pushed down from the support rod 132, so that the traction rod 11 is stationary in a direction parallel to the ground due to gravity. The fixed wheel 23 is connected to the control rod 242 to fix it to the fixed frame 21, so that the locking rod 241 is vertically set in the multiple slide grooves 22 in the natural state. The material cart where the traction rod 11 is located is pushed to push the traction rod 11 into the fixed frame 21. As the traction rod 11 is pushed into the fixed frame 21, the locking rod 241 in the natural state is pushed up by the traction rod 11, and when the locking rod 241 is pushed to a certain height, it slides off the traction rod 11 and is locked between the cross bar 111 and the traction rod 11. The slide groove 22 provides support for the locking rod 241 to lock the traction rod 11. When separating, the control rod 242 is stepped on by foot to control the locking rod 241 to leave the traction rod 11 , and at the same time, the material cart where the traction rod 11 is located is pulled to pull the traction rod 11 away from the fixing frame 21 .

[0031] Compared with the prior art, the utility model provides a material cart traction structure, which realizes the connection and disconnection between multiple material carts by setting the buckle structure 10 and the locking and separating device 20. Push the traction rod 11 down from the support rod 132 so that the traction rod 11 is stationary in a direction parallel to the ground due to gravity. Push the material cart where the traction rod 11 is located to push the traction rod 11 into the fixed frame 21. As the traction rod 11 is pushed into the fixed frame 21, the locking rod 241 in a natural state is pushed up by the traction rod 11, and when the locking rod 241 is pushed to a certain height, it slides off the traction rod 11 and is locked between the cross bar 111 and the traction rod 11. When separating, step on the control rod 242 with your foot to control the locking rod 241 to leave the traction rod 11, and at the same time pull the material cart where the traction rod 11 is located to pull the traction rod 11 away from the fixed frame 21.

Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
