Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, specifically a handcart for handling paint. Background Technology

[0002] Paint handling trolleys are labor-saving devices specifically designed for short-distance paint transportation. Their core function is to replace manual carrying with wheeled operation, preventing paint buckets from tipping over or colliding during transport, thus avoiding spillage and damage. They are widely applicable to scenarios such as goods organization in paint warehouses, material transfer at construction sites, and small-batch deliveries to stores. They effectively reduce manual labor and minimize paint waste and contamination during handling, making them a practical tool for improving the safety and convenience of paint storage and use.

[0003] However, existing technologies still have significant shortcomings, such as: Most existing handcarts are fixed designs, which take up a lot of space when transported by vehicle, wasting space in the transport vehicle. Utility Model Content

[0004] The purpose of this utility model is to provide a handcart for transporting paint, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A handcart for transporting paint includes a main frame, two symmetrical sub-frames rotatably mounted on the main frame, each sub-frame rotatably mounted with a movable wheel, a support plate rotatably mounted on the bottom of the main frame, a limit block fixedly mounted on the bottom of the support plate, and an arc-shaped rod rotatably mounted in the middle of the main frame. A fixed rod is rotatably mounted on one of the sub-frames, and a fixed column is fixedly mounted on the other sub-frame. Both the fixed rod and the fixed column are provided with external threads, and a threaded sleeve is fitted onto the external thread of the fixed rod. A handrail is fixedly installed on the sub-frame.

[0006] Preferably, a magnet is fixedly mounted on the fixing rod.

[0007] Preferably, a reinforcing plate is fixedly installed on the main frame, and a limiting plate is fixedly installed on the secondary frame. When the device is unfolded, the limiting plate abuts against the reinforcing plate.

[0008] Preferably, the main frame is provided with two symmetrical fixing rings, one of which is fixedly provided with an elastic band, and the other end of the elastic band is fixedly provided with a hook.

[0009] Preferably, the handrail is fitted with a handle cover, and the handle cover is provided with several anti-slip textures.

[0010] Preferably, a protective ring is fixedly provided on the handle.

[0011] Preferably, two symmetrical protective plates are fixedly installed on the main frame.

[0012] Preferably, the threaded sleeve is fixedly provided with several anti-slip strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The device features a rotatable design, allowing for complete folding and storage: In use, the sub-frame is unfolded until perpendicular to the main frame, maintaining stability through the contact of the limiting plate and reinforcing plate; for storage, the sub-frame and support plate are rotated in the opposite direction, causing all components to fold around the main frame, significantly reducing the overall size of the device. Compared to traditional fixed handcarts, it is easier to place in the trunk of a transport vehicle, a corner of a warehouse, or other spaces after folding, reducing storage and transportation space requirements.

[0014] 2. To unfold, simply rotate the fixing rod to align it with the fixing column, and the magnet will quickly align them. Then, rotate the threaded sleeve with anti-slip strips to lock it in place. To fold, simply rotate the threaded sleeve in the opposite direction to release the lock. No complicated tools or multiple steps are required. The entire folding and unfolding process can be completed by a single person, making it more efficient than traditional folding trolleys that require disassembly of parts. This meets the convenience requirements of mobile operations in construction scenarios. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-5 This utility model provides a technical solution: The device uses a main frame 1 as its core load-bearing structure. Two symmetrically distributed sub-frames 2 are rotatably connected to both sides of the main frame 1, and both can rotate around their connection points with the main frame 1. Each sub-frame 2 has a rotatable wheel 3 at its bottom, which can adjust its posture as the sub-frame 2 rotates. A support plate 4 is rotatably mounted at the bottom of the main frame 1, and the support plate 4 can rotate around its connecting axis to the main frame 1. A limit block 41 is fixedly mounted at the bottom of the support plate 4 to limit its rotation angle. An arc-shaped rod 5 is rotatably mounted in the middle of the main frame 1, and the arc-shaped rod 5 can rotate around its connection point with the main frame 1.

[0019] When the device needs to be unfolded for paint transport, rotate the sub-frame 2 to unfold it. The moving wheels 3 rotate with the sub-frame 2 to a position in contact with the ground, providing support for the device's movement. Rotate the support plate 4 to make it perpendicular to the main frame 1. The limiting block 41 abuts against the ground or the main frame 1 to prevent the support plate 4 from rotating excessively. At this time, the support plate 4 can be used to support the paint bucket. The arc-shaped rod 5 can be rotated to a suitable position as needed to help limit the paint bucket. When the device needs to be folded, rotate the sub-frame 2, support plate 4, and arc-shaped rod 5 in the opposite direction to fold the components around the main frame 1, reducing the device's size and making it easier to store and carry.

[0020] A fixing rod 6 is rotatably mounted on one of the sub-frames 2, and a magnet 61 is fixedly installed on the fixing rod 6. The magnet 61 is used to attract the fixing rod 6 to the sub-frame 2 when it is stored. A fixing post 7 is fixedly mounted on the other sub-frame 2. The outer circumferential surfaces of the fixing rod 6 and the fixing post 7 are both provided with external threads. A threaded sleeve 8 is fitted on the external thread of the fixing rod 6, and several anti-slip strips 81 are fixedly provided on the outer circumferential surface of the threaded sleeve 8.

[0021] When locking the unfolded sub-frame 2, rotate the fixing rod 6 to align the external threads of the fixing rod 6 and the fixing post 7 coaxially. Then rotate the threaded sleeve 8. Since the internal threads of the threaded sleeve 8 are compatible with the external threads of the fixing rod 6 and the fixing post 7, and the anti-slip strip 81 increases the friction between the hand and the threaded sleeve 8, it is easier for the operator to apply force. This allows the threaded sleeve 8 to be threadedly connected to both the fixing rod 6 and the fixing post 7, stably locking the two sub-frames 2 in the unfolded state and preventing them from rotating accidentally during transportation. When folding the sub-frame 2, rotate the threaded sleeve 8 in the opposite direction to separate it from the fixing post 7, and then rotate the fixing rod 6 to offset it from the fixing post 7. This releases the lock on the sub-frame 2, allowing it to be folded.

[0022] A handrail 9 is fixedly installed on the sub-frame 2. A handle 91 is fitted on the outer circumference of the handrail 9. Several anti-slip textures 911 are distributed on the outer surface of the handle 91, and a protective ring 912 is fixedly installed on the handle 91.

[0023] When the operator pushes the device to move the paint, the hand grips the handle 91. The anti-slip texture 911 increases the friction between the hand and the handle 91, which can effectively prevent the hand from slipping, improve the stability of the grip, and facilitate precise control of the device's moving direction and speed. The protective ring 912 can limit the operator's hand, preventing the hand from accidentally slipping off the handle 91 during the application of force, further ensuring operational safety, and allowing the operator to move the device and paint bucket stably and safely by using the handle 9.

[0024] A reinforcing plate 10 is fixedly installed on the main frame 1, and a limiting plate 11 is fixedly installed on the secondary frame 2. Two symmetrically distributed fixing rings 12 are provided on the main frame 1, one of which is fixedly equipped with an elastic band 121, and the other end of the elastic band 121 is fixedly equipped with a hook 1211. Two symmetrical protective plates 13 are also fixedly installed on the main frame 1.

[0025] When the sub-frame 2 is unfolded, the limiting plate 11 on the sub-frame 2 abuts against the reinforcing plate 10 of the main frame 1, limiting the unfolding angle of the sub-frame 2 and ensuring that the sub-frame 2 remains stable after unfolding, providing a reliable support structure for the device. When transporting the paint bucket, place the paint bucket in the bearing area of ​​the device, and wrap the elastic band 121 around one side of the paint bucket so that the hook 1211 is attached to another fixing ring 12. The elastic tension of the elastic band 121 can firmly fix the paint bucket to the device, preventing the paint bucket from shaking or tipping over during transportation.

[0026] The protective plate 13 protects the casters 3 from collision damage during storage or transportation.

[0027] Working principle: In use, rotate the two sub-frames 2 by 90 degrees so that the limiting plates 11 on the sub-frames 2 abut against the reinforcing plates 10 of the main frame 1, achieving stable positioning of the sub-frames 2 in the unfolded state; then rotate the fixing rod 6, and with the help of the magnet 61 on the fixing rod 6 for positioning, make the fixing rod 6 coaxial with the fixing column 7. Then rotate the threaded sleeve 8 (with the anti-slip strip 81 for easy force application), so that the threaded sleeve 8 connects the fixing rod 6 and the fixing column 7 at the same time, completing the folding and locking of the sub-frames 2; then rotate the support plate 4 so that it is perpendicular to the main frame 1, and the limiting block 41 can prevent the support plate 4 from rotating excessively. At this time, the paint bucket can be placed on the support plate 4, and the paint bucket can be fixed by the fixing ring 12, elastic band 121 and hook 1211 to prevent shaking during transportation; the operator holds the handle 91 with anti-slip texture 911 and protective ring 912, pushes the handle 9, and moves the device through the moving wheels 3 to realize the transportation of the paint bucket. When folding, follow the reverse of the above operation: first rotate the threaded sleeve 8 to separate it from the fixed column 7, rotate the fixed rod 6, then rotate the sub-frame 2 back to its original position, and rotate the support plate 4 to fit it against the main frame 1. This completes the folding and storage of the device. The protective plate 13 can provide some protection for the components after folding.

[0028] Working principle: In the process of using this utility model, when the device is in use, the sub-frame 2 is first unfolded: the two sub-frames 2 are rotated 90 degrees around the connection point with the main frame 1 until the limiting plate 11 on the sub-frame 2 and the reinforcing plate 10 on the main frame 1 abut against each other. The rigid contact between the two restricts the sub-frame 2 from continuing to rotate, so that the sub-frame 2 is stably kept in the unfolded state, providing a support foundation for the device.

[0029] Then, the sub-frame 2 is locked: rotate the fixing rod 6 on one of the sub-frames 2, and then rotate the threaded sleeve 8 sleeved on the fixing rod 6. The anti-slip strip 81 on the outer circumference of the threaded sleeve 8 increases the friction between the hand and the sleeve, making it easier for the operator to apply force, so that the threaded sleeve 8 moves along the external thread of the fixing rod 6 until it is simultaneously screwed into the external thread of the fixing post 7. Through the threaded connection between the threaded sleeve 8 and the two, the two sub-frames 2 are rigidly fixed, preventing the sub-frames 2 from loosening due to vibration or external force during use.

[0030] After the subframe 2 is fixed, adjust the support plate 4: rotate the support plate 4 at the bottom of the main frame 1 so that it rotates around the connecting shaft until it is perpendicular to the main frame 1. At this time, the limiting block 41 at the bottom of the support plate 4 will abut against the main frame 1 or the ground, preventing the support plate 4 from continuing to rotate and ensuring that the support plate 4 maintains a horizontal bearing posture.

[0031] Next, place and secure the paint bucket: Place the paint bucket stably on the support plate 4, take out the elastic band 121 connected to one of the fixing rings 12 on the main frame 1, wrap the elastic band 121 around the paint bucket, and then hook the hook 1211 at the end of the elastic band 121 onto another fixing ring 12. Use the elastic tension of the elastic band 121 to tightly bind the paint bucket to the device to prevent the paint bucket from shaking or tipping over during transportation.

[0032] When the operator pushes the device, their hands grip the handle 91 of the handle bar 9 on the sub-frame 2. The anti-slip texture 911 on the surface of the handle 91 increases the friction between the hand and the handle 91, preventing slippage when the hands are sweaty or contaminated with paint. The protective ring 912 on the handle 91 restricts the hand position and prevents the hand from slipping off the end of the handle 91 when pushing with force, ensuring that the operator can apply force stably. The entire device and paint bucket are moved by the moving wheels 3 at the bottom of the sub-frame 2, realizing convenient transportation of paint.

[0033] When the device needs to be folded and stored, reverse the steps above: rotate the threaded sleeve 8 to separate it from the fixed post 7, then rotate the fixed rod 6 to offset it from the fixed post 7, releasing the lock of the sub-frame 2; then rotate the two sub-frames 2 in the opposite direction to reset them, so that they are gathered on both sides of the main frame 1; finally, rotate the support plate 4 so that it rotates around the connecting shaft until it fits against the main frame 1, completing the overall folding.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
