[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a material handling trolley for construction, comprising a trolley body 1, which serves as the main frame of the entire material handling trolley. Wheels are provided on the lower side, and a push rod is provided on the rear side. A connecting mechanism 2 is provided on the front side of the trolley body 1. The connecting mechanism 2 includes a connecting component 21 and an auxiliary component 22. The connecting component 21 includes a rotating member 211, which is rotatably connected to the front side of the trolley body 1, enabling flexible rotation. Through cooperation with a connecting bending plate 212, it can provide a larger support area for long, narrow materials, thus facilitating the transportation of materials of different specifications and improving the handling efficiency of the device. The connecting bending plate 212 is arc-shaped, and is fixedly connected to the rear left side of the rotating member 211. Cooperating with a limiting member 214, it can limit the rotation angle of the rotating member 211. The connecting bending plate 212 slides on the inner left wall of the trolley body 1.

[0033] Reference Figure 4 and Figure 6A housing 213 is fixedly connected to the upper front side of the vehicle body 1, providing protection and guidance for the internal limiting member 214, connecting rod 215, and compression spring 216. The limiting member 214 is slidably connected to the inner wall of the housing 213. Through cooperation with the connecting bending plate 212, it achieves precise control and fixation of the rotation angle of the rotating member 211. A protrusion is provided on the lower side of the limiting member 214. The lower part of the limiting member 214 is inserted into the left inner wall of the connecting bending plate 212. The connecting rod 215 is fixedly connected to the upper part of the limiting member 214, serving as the operating rod between the operator and the limiting member 214. Through the medium, the operator can easily control the up and down movement of the limiting member 214 by pulling or pushing the connecting rod 215, thereby realizing the connection and unlocking operation of the rotating member 211. The outer side of the connecting rod 215 slides on the upper inner wall of the outer shell 213. The limiting member 214 and the outer shell 213 are elastically connected by a compression spring 216. The compression spring 216 provides a continuous elastic restoring force for the limiting member 214. The compression spring 216 keeps the limiting member 214 in the state of being inserted into the connecting bent plate 212, ensuring the stable limiting of the rotating member 211.

[0034] Reference Figure 3 and Figure 4 The auxiliary component 22 includes a fixing sleeve 221, which is fixedly connected to the upper rear side of the outer casing 213. The fixing sleeve 221 provides a stable sliding track and mounting base for the limiting post 222, ensuring that the limiting post 222 can slide accurately back and forth on the inner wall of the fixing sleeve 221. This allows for effective limiting and unlocking of the connecting rod 215. The limiting post 222 is slidably connected to the inner wall of the fixing sleeve 221, providing additional limiting for the connecting rod 215. When the limiting post 222 is inserted into the connecting rod 215, it restricts the vertical movement of the connecting rod 215, ensuring that the limiting member 214 is fixed in position within the connecting bend 212, thus enhancing the stability and reliability of the connecting mechanism 2. The front side of the limiting post 222 is inserted into the inner wall of the connecting rod 215. A pull ring 223 is provided on the upper part of the connecting rod 215, providing a convenient and comfortable operating handle for the operator. The operator can easily apply pulling force to the connecting rod 215 by hooking the pull ring 223 with their fingers or tools, thereby controlling the limiting member 214.

[0035] Reference Figure 1 , Figure 2 and Figure 5A limiting component 3 is installed inside the vehicle body 1. The limiting component 3 includes a slide rail 31, which provides vertical sliding guidance for the limiting barrier 33. The slide rail 31 is fixedly connected to the inside of the vehicle body 1. An insertion hole 32 is opened on the inner wall of the slide rail 31, which tightly cooperates with the insertion rod 34 on the front inner wall of the limiting barrier 33 to realize the function of fixing and positioning the limiting barrier 33. This ensures the durability and stability of the limiting effect of the limiting barrier 33 on materials, further improves the safety and stability of material handling, and improves the handling efficiency of the device. The limiting barrier 33 is slidably connected to the inner wall of the slide rail 31. According to the actual size and shape of the material, the position can be flexibly adjusted inside the vehicle body 1 to achieve precise limiting and fixing of the material. The inner wall of the front side of the limiting bar 33 is slidably connected to the insertion rod 34. The insertion rod 34 is set in an L shape and is used to cooperate with the insertion hole 32 to fix the limiting bar 33. The insertion rod 34 is inserted into the inner wall of the insertion hole 32. The inner wall of the front side of the limiting bar 33 is provided with a return spring 35, which connects the two sets of insertion rods 34 and provides continuous elastic restoring force to the insertion rod 34, so that the insertion rod 34 keeps the insertion hole 32 in a fixed position, ensuring the stable limiting of the limiting bar 33.

[0036] Working Principle: When using the material handling trolley to move materials, if long strips of material need to be moved, the operator can hook the pull ring 223 on the upper part of the connecting rod 215 with their fingers or tools and pull the connecting rod 215 upwards. This causes the limiting member 214 to overcome the elastic force of the compression spring 216 and move upwards, disengaging from the connecting bend plate 212. This releases the restriction on the rotating member 211, allowing it to rotate freely and adjust to fit the shape of the material, thus providing a larger support area for the material. During rotation, the connecting bend plate 212 slides on the inner wall of the left side of the trolley body 1. When it rotates to the appropriate position, under the action of the compression spring 216, the protrusion at the lower part of the limiting member 214 tightly inserts into the inner wall of the connecting bend plate 212, precisely limiting the rotation angle of the rotating member 211 and ensuring its stable support of the material.

[0037] Furthermore, when the trolley is not being towed by the connecting mechanism 2 or during transportation, the limiting post 222 inside the fixed sleeve 221 can be inserted forward into the inner wall of the connecting rod 215. Under the vertical pressing force of the connecting rod 215, the connecting rod 215 is prevented from moving due to vibration or other unexpected factors, thereby ensuring the stability of the position of the limiting part 214, avoiding accidental unlocking or loosening of the connecting mechanism 2, and improving transportation safety.

[0038] If it is necessary to handle materials of different sizes, the operator can manually overcome the elasticity of the return spring 35, pull the plug rod 34 out of the socket 32, and then slide the limit bar 33 to the new position. After releasing, the return spring 35 will push the plug rod 34 to re-insert into the socket 32, so as to quickly fix and adjust the limit bar 33, which can conveniently and quickly adapt to the handling needs of materials of different sizes.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
