Description

Technical Field

[0001] This utility model relates to the field of handcart technology, specifically to an adjustable width cargo box for a handcart. Background Technology

[0002] Currently, most handcarts on the market have fixed-width cargo bins, and their carrying capacity cannot be adjusted according to actual usage needs. When transporting materials, if the quantity or size of the materials is small, the space utilization rate of the fixed-width cargo bin is low, which can easily lead to a decrease in transportation efficiency. If the quantity or size of the materials is too large, some materials cannot be accommodated, requiring multiple transports, increasing the number of operations and labor costs. In some cases, forced loading may even cause the materials to tilt or slip, resulting in material damage or transportation safety hazards.

[0003] Meanwhile, the few existing cargo bins with width adjustment functions either have poor stability of the adjustment structure and are prone to jamming during the sliding process, or lack effective anti-fall-off design. During adjustment, the extension plate is prone to detach from the main structure, which not only affects the user experience but also poses a safety risk. They are difficult to meet the comprehensive requirements of cargo bin adaptability, stability and safety in actual transportation scenarios. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an adjustable width cargo box for a handcart to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An adjustable-width cargo bin for a handcart includes: a base plate, rollers, limiting rods, a U-shaped plate, and a handle. Four rollers are fixedly installed at the bottom of the base plate. Four limiting rods are fixedly embedded inside the base plate. A stabilizing plate is fixedly installed on the top of the base plate. The side of the stabilizing plate away from the base plate is fixedly connected to the U-shaped plate. The handle is fixedly installed on the outside of the U-shaped plate. The handcart also includes: slots, grooves, and locking plates. Two slots are located on both sides of the U-shaped plate. Four grooves are located on the outside of the U-shaped plate. Four locking plates are slidably connected inside the slots. Two extension plates are fixedly welded to the outside of the four locking plates. The locking grooves are located at the bottom of the U-shaped plate and correspond to the limiting rods. Finally, bolts and U-shaped rods are included. The bolts are threaded into the inside of the U-shaped plate and extend into the grooves. The U-shaped rods are fixedly installed on the outside of the extension plates.

[0006] Furthermore, the outer diameter of the limiting rod is adapted to the inner diameter of the limiting groove, and the length of the limiting rod is greater than the length of the limiting groove, so as to limit the outward movement of the extension plate and prevent the extension plate from falling off.

[0007] Furthermore, the width of the card plate is adapted to the width of the card slot, and the length of the card plate is less than the length of the card slot, so that the card plate can slide stably along the card slot to drive the extension plate to adjust the width.

[0008] Furthermore, the grooves are positioned to correspond one-to-one with the bolt installation positions, and the depth of the grooves is greater than the length of the bolt extension end, to prevent the bolt end from protruding beyond the U-shaped plate and affecting operation.

[0009] Furthermore, the top of the extension plate is flush with the top of the U-shaped plate, and the thickness of the extension plate is the same as the thickness of the U-shaped plate, ensuring that the bearing surface is flat after the cargo compartment is unfolded so as to stably place the goods.

[0010] Furthermore, the installation height of the U-shaped rod is adapted to the installation height of the handle, and the material of the U-shaped rod is the same as that of the extension plate, ensuring structural strength and facilitating gripping and pulling of the extension plate.

[0011] Furthermore, the width of the stabilizing plate is the same as the width of the base plate, and the length of the stabilizing plate is adapted to the length of the U-shaped plate to enhance the stability of the connection between the U-shaped plate and the base plate.

[0012] Furthermore, the number of bolts is the same as the number of grooves, and the ends of the bolts are provided with anti-slip textures to facilitate twisting the bolts to fix or loosen the extension plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The adjustable width of the handcart's cargo bin is flexible and adaptable: the width of the cargo bin can be adjusted by pulling the extension plate, which can flexibly change the carrying space according to the quantity (when there is too much) or size (when the size is too large) of the materials. This solves the problem of the limited material capacity of traditional fixed-width cargo bins and makes it applicable to a wider range of scenarios.

[0014] 2. The adjustable width of the trolley's cargo bin ensures a stable and safe adjustment process with a reliable anti-fall-off design: During adjustment, the extension plate slides through the dual cooperation of the locking plate and the locking groove, and the limiting groove and the limiting rod. This ensures the smoothness of the sliding process and limits the excessive outward movement of the extension plate through the limiting rod, effectively preventing the extension plate from falling off and improving the safety of the adjustment operation.

[0015] 3. The adjustable width of the handcart's cargo bin is structurally stable and has reliable load-bearing capacity: the bottom plate and the U-shaped plate are connected by a stabilizing plate of appropriate size, which can evenly transfer the weight of the goods and reduce structural swaying; the extension plate is flush with the top of the U-shaped plate and has the same thickness, ensuring that the load-bearing surface is flat, which can stably place the goods and prevent the goods from tilting and slipping during transportation, thus ensuring the reliability of the load-bearing capacity.

[0016] 4. The adjustable width of the trolley's cargo compartment is easy to operate and highly practical: to adjust, simply twist the bolt with anti-slip texture at the end to lock or unlock. Combined with the U-shaped rod that matches the height of the handle, the operator can easily complete the width adjustment without making large adjustments. Moreover, the bolt is hidden in the groove, so it will not scratch the goods or interfere with the movement of the trolley, resulting in a better user experience.

[0017] 5. The adjustable width of the trolley's cargo compartment makes it easy to move and provides solid basic functions: The four rollers at the bottom of the base provide stable movement for the trolley, and with the handle on the outside of the U-shaped plate, it can be used as conveniently as a regular trolley when the width is not adjusted, thus balancing adjustable functions with basic mobility needs.

[0020] 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.

[0021] Example: Please refer to the following: Figure 1-5 , An adjustable-width cargo box for a handcart includes: a base plate 1, rollers 2, limiting rods 3, a U-shaped plate 4, and a handle 5. Four rollers 2 are fixedly installed at the bottom of the base plate 1. Four limiting rods 3 are fixedly embedded inside the base plate 1. A stabilizing plate is fixedly installed on the top of the base plate 1, and the side of the stabilizing plate away from the base plate 1 is fixedly connected to the U-shaped plate 4. The handle 5 is fixedly installed on the outside of the U-shaped plate 4. The handcart also includes slots 6, grooves 7, and locking plates 8. Two slots 6 are formed on both sides of the U-shaped plate 4. On the side, there are four grooves 7 on the outside of the U-shaped plate 4, and four clamping plates 8 are slidably connected to the inside of the clamping groove 6; there are two extension plates 9 and four clamping plates 8 fixedly welded to the outside of the extension plates 8, and the clamping groove 10 is opened at the bottom of the U-shaped plate 4, and the clamping groove 10 is correspondingly set with the clamping rod 3; there are bolts 11 and U-shaped rods 12, the bolts 11 are threadedly connected to the inside of the U-shaped plate 4 and extend into the grooves 7, and the U-shaped rods 12 are fixedly installed on the outside of the extension plates 9; Specifically, firstly, the base plate 1 serves as the core load-bearing component, with four rollers 2 at the bottom providing mobility for the entire trolley, and four internally fixed limiting rods 3 providing a guiding foundation for subsequent width adjustment; the U-shaped plate 4 is connected to the base plate 1 via a top stabilizing plate, forming the main frame of the cargo bin, and the handle 5 on the outside is used to push the trolley; when the width needs to be adjusted, the bolt 11 inside the U-shaped plate 4 is turned to loosen it from the groove 7, releasing the lock on the extension plate 9; at this time, the U-shaped rod 12 on the outside of the extension plate 9 is held to pull the extension plate 9, causing the locking plate 8 fixed on its inner side to slide along the slots 6 on both sides of the U-shaped plate 4, while the limiting groove 10 at the bottom of the extension plate 9 slides synchronously along the limiting rod 3 on the base plate 1, realizing the lateral adjustment of the width; after adjusting to the target width, the bolt 11 is turned in the opposite direction to re-tighten the structure inside the groove 7, locking the relative position of the locking plate 8 and the slot 6, completing the width fixation, and ensuring that the cargo bin remains stable during use; In the embodiment: the outer diameter of the limiting rod 3 is adapted to the inner diameter of the limiting groove 10, and the length of the limiting rod 3 is greater than the length of the limiting groove 10, so as to limit the outward movement of the extension plate 9 and prevent the extension plate 9 from falling off. Specifically, the outer and inner diameters of the limiting rod 3 and the limiting groove 10 are matched to ensure that they fit tightly during sliding and prevent the extension plate 9 from shaking. The length of the limiting rod 3 is greater than the length of the limiting groove 10. When the extension plate 9 slides outward to its maximum stroke, the end of the limiting groove 10 will contact the end of the limiting rod 3 to form a physical block, preventing the extension plate 9 from slipping out of the constraints of the slot 6 and the limiting rod 3 due to excessive sliding. This fundamentally avoids the risk of the extension plate 9 falling off during the adjustment process and ensures structural safety. In the embodiment: the width of the card plate 8 is adapted to the width of the card slot 6, and the length of the card plate 8 is less than the length of the card slot 6, so that the card plate 8 can slide stably along the card slot 6 to drive the extension plate 9 to adjust the width. Specifically, the width of the pallet 8 is matched with the width of the slot 6 to ensure that there is no lateral gap when the pallet 8 slides in the slot 6, thus preventing the extension plate 9 from shifting left or right when adjusting or carrying goods. At the same time, the length of the pallet 8 is less than the length of the slot 6, which provides enough sliding space for the pallet 8, allowing the extension plate 9 to move stably along the slot 6 with the pallet 8. This enables smooth adjustment of the width of the cargo bin, ensuring the stability of the adjustment process and preventing adjustment jams caused by improper matching of the pallet 8 and the slot 6. In the embodiment: the opening position of the groove 7 corresponds one-to-one with the installation position of the bolt 11, and the depth of the groove 7 is greater than the length of the extension end of the bolt 11, so as to avoid the end of the bolt 11 protruding out of the outside of the U-shaped plate 4 and affecting the operation. Specifically, the groove 7 corresponds one-to-one with the installation position of the bolt 11, ensuring that the bolt 11 can be accurately inserted into the groove 7 to effectively lock the relevant structure of the extension plate 9; and the depth of the groove 7 is greater than the length of the extension end of the bolt 11, so that after the bolt 11 is tightened, its end will not protrude from the outside of the U-shaped plate 4; this design can prevent the end of the bolt 11 from scratching the goods or hindering the operator from pushing the handle 5, while preventing the end of the bolt 11 from being damaged by external force collision, ensuring the reliability of the locking function and the safety of the use process; In the embodiment: the top of the extension plate 9 is flush with the top of the U-shaped plate 4, and the thickness of the extension plate 9 is the same as the thickness of the U-shaped plate 4, to ensure that the bearing surface is flat after the cargo box is unfolded so as to stably place the goods. Specifically, the top of the extension plate 9 is flush with the top of the U-shaped plate 4 and has the same thickness, so that the entire bearing surface remains level and flat, without height differences or steps, whether the cargo bin is in the unfolded or unfolded state. This structural design can prevent goods from tilting or slipping due to uneven bearing surfaces. Especially when transporting irregular or easily rolling goods, it can ensure that the goods are evenly stressed, improve the stability during transportation, and facilitate the loading and unloading of goods. In the embodiment: the installation height of the U-shaped rod 12 is adapted to the installation height of the handle 5, and the material of the U-shaped rod 12 is the same as the material of the extension plate 9, to ensure structural strength and facilitate gripping and pulling the extension plate 9; Specifically, the installation height of the U-shaped rod 12 is adapted to the handle 5. When the operator pushes the handle 5 to move the trolley, they can easily hold the U-shaped rod 12 to adjust the width without making large adjustments to their hand position, reducing the complexity of the operation. The U-shaped rod 12 and the extension plate 9 are made of the same material, which can ensure that the physical properties of the two, such as strength and toughness, are matched. This avoids damage caused by uneven stress on the connection parts due to material differences, extends the service life of the U-shaped rod 12, and ensures the reliability of long-term adjustment operation. In this embodiment: the width of the stabilizing plate is the same as the width of the base plate 1, and the length of the stabilizing plate is adapted to the length of the U-shaped plate 4, so as to enhance the stability of the connection between the U-shaped plate 4 and the base plate 1. Specifically, the width of the stabilizing plate is the same as the width of the bottom plate 1, and the length is adapted to the length of the U-shaped plate 4, so that the stabilizing plate can completely cover the connection area between the U-shaped plate 4 and the bottom plate 1, increasing the contact area between the two; when carrying goods, the stabilizing plate can evenly transfer the weight of the goods borne by the U-shaped plate 4 to the bottom plate 1, avoiding deformation or breakage of the connection part due to excessive local stress, while reducing the shaking of the U-shaped plate 4 during the movement of the trolley, and improving the stability of the entire cargo box structure; In the embodiment: the number of bolts 11 is the same as the number of grooves 7, and the ends of the bolts 11 are provided with anti-slip textures, which makes it easy to twist the bolts 11 to fix or loosen the extension plate 9. Specifically, the number of bolts 11 is the same as that of groove 7, which can form multi-point locking at different positions of U-shaped plate 4, avoiding uneven force on extension plate 9 and displacement caused by locking a single bolt 11, thus improving the stability after locking; the anti-slip texture at the end of bolt 11 can increase the friction between the hand and the end of bolt 11, making it less likely for the operator to slip when turning bolt 11. Even if the hands are covered with dust or slight oil, the tightening or loosening of bolt 11 can be easily completed, improving the convenience of the adjustment process; Working principle: When the adjustable width hopper of this handcart is not in use, it can be moved directly like a regular handcart using the rollers 2 at the bottom of the base plate 1 and controlled by the handle 5 on the outside of the U-shaped plate 4. When it is necessary to adjust the width of the hopper to accommodate more or larger materials, first turn the bolt 11 extending to the groove 7 inside the U-shaped plate 4 to loosen it, then hold the U-shaped rod 12 on the outside of the extension plate 9 and pull the extension plate 9. At this time, the retaining plate 8 on the inside of the extension plate 9 slides along the retaining grooves 6 on both sides of the U-shaped plate 4, and the limiting groove 10 at the bottom of the extension plate 9 slides along the limiting rod 3 inside the base plate 1. The limiting rod 3 and the limiting groove 10 cooperate to restrict the extension plate 9 from moving outward too much to prevent it from falling. After the width is adjusted to be appropriate, turn the bolt 11 in the opposite direction to lock the position of the extension plate 9 and complete the adjustment.
