[0002] Plastic products are polymers formed through addition or condensation polymerization, commonly known as plastics or resins, and their composition and shape can be freely altered. Plastic products require specialized transport equipment to move them from one location to another for further processing or storage. Currently, trolleys are commonly used for transport, with workers manually placing items on the trolley and then pushing it to its destination. However, the placement area at the bottom of the trolley often requires operators to bend over, which is inconvenient, increases labor intensity, and affects work efficiency. Therefore, this invention provides a transport device for plastic products to meet these needs. Utility Model Content

[0025] like Figures 1 to 3As shown, an embodiment of this utility model provides a transport device for plastic products, including a base frame 1, a support 2 and a first slide bar 3 fixedly connected to the top of the base frame 1, a second slide bar 4 fixedly connected to the outer wall of the support 2, and a bottom support plate 5 and a middle support plate 6 slidably connected to the outer wall of the first slide bar 3; and a lifting assembly, which drives the bottom support plate 5 to move upward. The lifting assembly is connected to the base frame 1 and the support 2. The lifting assembly can realize the lifting and lowering of the bottom support plate 5, so that when the trolley needs to place or pick up plastic products, the bottom support plate 5 can be raised to a suitable height according to the needs of the operator, thereby facilitating the loading and unloading of plastic products, reducing the labor intensity of the operator, and improving work efficiency.

[0026] As one implementation method in this embodiment, such as Figure 4 and Figure 5 As shown, the lifting assembly includes a first pulley group 7 fixedly connected to the top of the inner wall of the bracket 2, and a second pulley group 8 fixedly connected to the outer wall of the bracket 2; it also includes a connecting frame 9 slidably connected to the outer wall of the second slide rod 4. Terminals 10 are fixedly connected to both sides of the bottom support plate 5 and the top of the connecting frame 9. A fixing box 11 is fixedly connected to the top of the base frame 1. A sliding sleeve 12 is fixedly connected to the top of the bottom support plate 5, and the sliding sleeve 12 is adapted to the first slide rod 3. A terminal 10 on one side of the bottom support plate 5 is connected to a terminal 10 on the top of the connecting frame 9 via a rope, the rope being wound around the outer wall of the first pulley group 7 and the second pulley group 8. A terminal 10 on the other side of the bottom support plate 5 is connected to a terminal 10 on the top of the connecting frame 9 via a rope, the rope being wound around the outer wall of the second pulley group 8. The lifting assembly is thus lifted by ropes. The four terminals 10 on both sides of the base plate 5 are connected to the four terminals 10 on the top of the connecting frame 9. Each rope is wrapped around the outer wall of the first pulley group 7 and the second pulley group 8 respectively, forming a four-point synchronous traction structure, which makes the base plate 5 more stable and reliable during the lifting process. When the foot pedal 16 on the connecting frame 9 is stepped on, the connecting frame 9 will move downward along the second slide bar 4. At this time, the rope will generate tension changes under the traction of the first pulley group 7 and the second pulley group 8, which will drive the four corners of the base plate 5 to move upward along the first slide bar 3. When the sliding sleeve 12 at the top of the base plate 5 touches the bottom of the middle plate 6, it will lift the middle plate 6 together. At this time, the middle plate 6 and the base plate 5 form an integral synchronous lifting structure, thereby raising the placement area and making it easier for operators to pick up and put down products from the middle plate 6 or the base plate 5.

[0027] In this embodiment, as Figures 5 to 9As shown, a spring 13 is fixedly connected to the inner wall of the fixing box 11, and a wedge block 14 is fixedly connected to the end of the spring 13. A "U"-shaped frame 15 is fixedly connected to the bottom of the fixing box 11. A foot pedal 16 is fixedly connected to the middle position of the top of the connecting frame 9. A connecting rod 17 is fixedly connected to the bottom of the connecting frame 9. A limit ring 18 is fixedly connected to the outer wall of the connecting rod 17. A push-in block 19 is fixedly connected to the end of the connecting rod 17. A sleeve block 20 is slidably connected to the outer wall of the connecting rod 17. A covering groove 21 is opened at the bottom of the sleeve block 20. The covering groove 21 is adapted to the push-in block 19. After stepping on the foot pedal 16 to push the push-in block 19 at the bottom of the connecting frame 9 downward into the fixing box 11, the inclined surface of the end of the push-in block 19 will contact the inclined surface of the wedge block 14 and push the wedge block 14 to retract inward. At this time, the spring 13 will be compressed. During the continuous downward movement of the push-in block 19, the inclined surface of the sleeve block 20 will contact the wedge block 14. Since the sleeve block 20 slides on the connecting rod 17, when the push-in block 19 moves downward, the sleeve block 20 will move upward along the connecting rod 17 and will be left on the inclined surface of the wedge block 14. The push-in block 19 will separate from the covering groove 21 at the bottom of the sleeve block 20. When the push-in block 19 is fully inserted into the fixing box 11, the wedge block 14 will be reset under the action of the spring 13. At this time, the top of the push-in block 19 abuts against the bottom of the wedge block 14, limiting and fixing the push-in block 19. At this time, the pressure on the foot pedal 16 is released. Through the connection of the rope, the connecting frame 9 will move upward under the weight of the bottom support plate 5 and the middle support plate 6, so that the contact between the push-in block 19 and the wedge block 14 is tighter, and the locking of the connecting frame 9 is more stable. At this time, the lifting assembly enters the locked state. Figure 6 When it is necessary to lower the base plate 5, the foot pedal 16 can be pressed again to unlock the lifting assembly. (See reference...) Figure 9 As the connecting frame 9 moves down again, the sleeve block 20 will contact the inclined surface of the wedge block 14 under the blocking action of the limiting ring 18 and push the wedge block 14 to retract inward. At this time, the spring 13 is compressed again. As the push-in block 19 continues to move down, the push-in block 19 will eventually contact the "U" shaped frame 15 at the bottom of the fixing box 11. At this time, the planes on both sides of the sleeve block 20 will fit with the plane part of the wedge block 14. Through the elastic force of the spring 13, the sleeve block 20 will be clamped in the plane part of the wedge block 14. Then, release the foot pedal 16, and the connecting rod 17 will drive the push-in block 19 to move upward into the covering groove 21 at the bottom of the sleeve block 20 and form a whole with the sleeve block 20. At this time, it will drive the sleeve block 20 to move upward together and leave the interior of the fixing box 11, completing the descent operation of the bottom support plate 5.

[0028] The working principle of the technical solution provided by this utility model is as follows: In use, the foot can be placed on the foot pedal 16. When the foot pedal 16 on the connecting frame 9 is stepped on, the connecting frame 9 will move downward along the second slide bar 4. At this time, the rope will generate tension changes under the traction of the first pulley group 7 and the second pulley group 8, thereby driving the four corners of the bottom support plate 5 to move upward along the first slide bar 3. When the sliding sleeve 12 at the top of the bottom support plate 5 touches the bottom of the middle support plate 6, it will lift the middle support plate 6 together. At this time, the middle support plate 6 and the bottom support plate 5 form an integral synchronous lifting structure, thereby raising the placement area. If the foot pedal 16 is stepped on again, the push block 19 at the bottom of the connecting frame 9 will move downward to the fixing box 1. Within 1, the inclined surface of the end of the push-in block 19 will contact the inclined surface of the wedge block 14 and push the wedge block 14 to contract inward. At this time, the spring 13 will be compressed. During the continuous downward movement of the push-in block 19, the inclined surface of the sleeve block 20 will contact the wedge block 14. Since the sleeve block 20 slides on the connecting rod 17, when the push-in block 19 moves downward, the sleeve block 20 will move upward along the connecting rod 17 and will be left on the inclined surface of the wedge block 14. The push-in block 19 will separate from the covering groove 21 at the bottom of the sleeve block 20. When the push-in block 19 is completely inserted into the fixing box 11, the wedge block 14 will be reset under the action of the spring 13. At this time, the push-in block 19 will be fully inserted into the fixing box 11. The top of block 19 abuts against the bottom of wedge block 14, limiting and fixing the push-in block 19. At this time, the pressure on foot pedal 16 is released. Through the rope connection, connecting frame 9 will move upward under the weight of the bottom support plate 5 and middle support plate 6, thereby making the contact between push-in block 19 and wedge block 14 tighter and making the locking of connecting frame 9 more stable. At this time, the lifting component is in the locked state. When it is necessary to lower the bottom support plate 5, foot pedal 16 can be stepped on again to unlock the lifting component. Connecting frame 9 moves down again, and sleeve block 20 will contact the inclined surface of wedge block 14 under the blocking action of limit ring 18 and push the wedge. Block 14 retracts inward, at which point spring 13 is compressed again. As the push-in block 19 continues to move downward, it eventually contacts the "U"-shaped frame 15 at the bottom of the fixing box 11. At this point, the planes on both sides of the sleeve block 20 will fit against the plane of the wedge block 14. Through the elastic force of spring 13, the sleeve block 20 is clamped in the plane of the wedge block 14. Then, the foot pedal 16 is released, and the connecting rod 17 will drive the push-in block 19 to move upward into the covering groove 21 at the bottom of the sleeve block 20, forming a whole with the sleeve block 20. At this point, the sleeve block 20 will move upward together, leaving the interior of the fixing box 11, completing the descent operation of the bottom support plate 5.
