For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] Please refer to Figures 1 to 3, the present invention provides a technical solution: a sand mold cart for casting, comprising a base 1 and a main rod 8; a main wheel 5 is provided on each of the left and right sides of the base 1, a handbrake 6 is provided on the main wheel 5, the base 1 is located at the middle position between the two main wheels 5, a support rod 2 is fixedly provided on the front side of the base 1, a folding rod 3 is provided on the front side of the support rod 2, the folding rod 3 is rotatably connected to the support rod 2, a support rod 4 is fixedly provided on the front side of the folding rod 3, the support rod 4 is parallel to the base 1, two oppositely distributed support wheels 7 are provided on the bottom surface of the support rod 4, and a positioning protrusion 11 is provided on the top surface of the support rod 2; the main rod 8 is fixedly provided at the middle position on the top surface of the base 1, a toolbox 9 is fixedly provided on the rear side of the main rod 8 near the base 1, a handle 10 is fixedly provided on the rear side of the main rod 8 away from the base 1, and two oppositely distributed hooks 12 are provided on the front side of the toolbox 9.

[0031] In this embodiment, when the cart needs to be used, after the folding rod 3 rotates around the rotating pin, the folding rod 3 is in an open state relative to the support rod 2 (as shown in the attachment Figure 1 ), and then the hopper for transporting the sand mold is installed and connected to the main rod 8, the support rod 2, the folding rod 3 and the support rod 4. At this time, the hanging ring on the rear side of the hopper matches the hook 12, and the positioning groove on the bottom surface of the hopper matches the positioning protrusion 11, ensuring that the hopper will not shake back and forth or left and right during transportation; when loading, lock the main wheel 5 with the handbrake 6, and then load the sand mold into the hopper. When pushing, unlock the handbrake 6, hold the handle 10 and push the cart. Since the main rod 8 provides a surface support for the hopper, and the support rod 2, the folding rod 3 and the support rod 4 provide another surface support for the hopper, and under the action of the hanging ring and the hook 12, and the positioning groove and the positioning protrusion 11, it is ensured that the hopper will not shake back and forth or left and right during transportation;

[0032] When the cart is not in use, remove the hopper and place it on the other side, then hold the handle 10 and press the cart towards the side of the toolbox 9, and then hold the folding rod 3. At this time, after the folding rod 3 rotates around the rotating pin, one end of the folding rod 3 is received inside the receiving groove of the support rod 2. At this time, the cart is in a folded state, reducing the occupied space and facilitating storage.

[0033] Furthermore, please refer to Figure 1 and Figure 2 , two main wheels 5 are oppositely distributed on the left and right sides of the base 1 and are rotatably connected to the base 1.

[0034] Furthermore, please refer to Figure 1 , the handbrake 6 is used to control the rotation and locking of the main wheel 5.

[0035] In this embodiment, two main wheels 5 are oppositely distributed on the left and right sides of the base 1 and are rotatably connected to the base 1. In this way, when the handbrake 6 is locked, the main wheel 5 will not rotate, and when the handbrake 6 is unlocked, holding the handle 10 can make the main wheel 5 rotate to realize the movement and docking of the cart.

[0036] Further, the gripping end of the handle 10 is provided with an anti-slip pad.

[0037] In this embodiment, the surface of the anti-slip pad is provided with anti-slip protrusions, so that it is not easy to slide when gripping the handle 10, facilitating operation and controlling the direction.

[0038] Further, a receiving groove is formed at the bottom of the support rod 2, and the receiving groove is matched with the folding rod 3.

[0039] Further, please refer to Figure 1 , the support rod 2 and the folding rod 3 are connected by a rotating pin.

[0040] Further, when the trolley is in a non-use state, after the folding rod 3 rotates around the rotating pin, one end of the folding rod 3 is received inside the receiving groove of the support rod 2.

[0041] Further, when the trolley is in a use state, after the folding rod 3 rotates around the rotating pin, the folding rod 3 is in an open state relative to the support rod 2. At this time, after the cart body is installed, it is connected to the main rod 8, the support rod 2, the folding rod 3 and the support bar 4.

[0042] Further, a positioning groove is formed at the bottom of the cart body, and the positioning groove is matched with the positioning protrusion 11.

[0043] Further, a hanging ring is provided on the rear side of the cart body, and the hanging ring is matched with the hook 12.

[0044] In this embodiment, when the trolley needs to be used, after the folding rod 3 rotates around the rotating pin, the folding rod 3 is in an open state relative to the support rod 2 (as shown in the Figure 1 figure), and then the cart body for transporting the sand mold is installed and connected to the main rod 8, the support rod 2, the folding rod 3 and the support bar 4. At this time, the hanging ring on the rear side of the cart body is matched with the hook 12, and the positioning groove on the bottom surface of the cart body is matched with the positioning protrusion 11, ensuring that the cart body will not shake forward or backward or left and right during transportation; when loading, lock the main wheel 5 with the handbrake 6, and then load the sand mold into the cart body. When pushing, unlock the handbrake 6 and grip the handle 10 to push the trolley. Since the main rod 8 provides a surface support for the cart body, and the support rod 2, the folding rod 3 and the support bar 4 provide another surface support for the cart body, and under the action of the hanging ring and the hook 12, and the positioning groove and the positioning protrusion 11, it is ensured that the cart body will not shake forward or backward or left and right during transportation;

[0045] When the trolley is not in use, remove the cart body and place it on the other side. Then grip the handle 10 and press the trolley towards the toolbox 9. Then grip the folding rod 3. At this time, after the folding rod 3 rotates around the rotating pin, one end of the folding rod 3 is received inside the receiving groove of the support rod 2. At this time, the trolley is in a folded state, reducing the occupied space and facilitating storage.

[0046] Working principle and usage process of the present invention: When the trolley is needed, after the folding rod 3 rotates around the rotating pin, the folding rod 3 is in an open state relative to the support rod 2 (as shown in the attached Figure 1 figure). Then, after installing the hopper for transporting the sand mold, it is connected to the main rod 8, the support rod 2, the folding rod 3 and the support rod 4. At this time, the hanging ring on the rear side of the hopper matches the hook 12, and the positioning groove on the bottom surface of the hopper matches the positioning protrusion 11, ensuring that the hopper will not shake back and forth or left and right during transportation; when loading goods, lock the main wheel 5 with the handbrake 6, and then load the sand mold into the hopper. When pushing, unlock the handbrake 6 and hold the handle 10 to push the trolley. Since the main rod 8 provides a surface support for the hopper, and the support rod 2, the folding rod 3 and the support rod 4 provide another surface support for the hopper, and under the action of the hanging ring and the hook 12, and the positioning groove and the positioning protrusion 11, it is ensured that the hopper will not shake back and forth or left and right during transportation; when the trolley is not in use, remove the hopper and place it on the other side, then hold the handle 10 and press the trolley towards the toolbox 9. Then hold the folding rod 3. At this time, after the folding rod 3 rotates around the rotating pin, one end of the folding rod 3 is received in the receiving groove of the support rod 2. At this time, the trolley is in a folded state, and the occupied space is reduced, which is convenient for storage.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
