[0002] Pallets are core load-bearing and transfer equipment in logistics transportation and material handling. They are typically made of high-strength materials and have standardized dimensions to adapt to various transport lines, warehouse racks, and transport vehicles. They are mainly used to centrally carry and stack goods, realizing the integrated flow of goods from warehousing and sorting to transportation and loading / unloading. They can reduce manual handling losses and improve the turnover efficiency of goods. They are key tools for connecting various links of the transport line and ensuring the continuity and standardization of logistics operations. They are widely used in various cargo transportation scenarios such as manufacturing, e-commerce warehousing, and cold chain logistics.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-5As shown, this utility model provides a retractable pallet device for a transport line, including a pallet base 1. An adjusting component 2 is fixedly installed in the middle of the bottom surface of the pallet base 1. The driving end of the adjusting component 2 is connected to a transmission frame 3. Slider 4 is fixedly connected to both ends of one side of the transmission frame 3. Support blocks 5 are fixedly fixedly connected to the bottom surface of the pallet base 1 in a symmetrical manner. A circular groove 51 is opened inside the support block 5. A transmission device 52 is rotatably connected inside the circular groove 51. The other end of the transmission device 52 is connected to the outside of the driving end of the adjusting component 2. A first support frame 11 is fixedly connected to the center of the top surface of the pallet base 1. A sliding groove 12 is symmetrically opened on the top surface of the pallet base 1. A support protrusion 6 is fixedly connected to the other side of the transmission frame 3. A second support frame 7 is fixedly connected to one end of the support protrusion 6. The support protrusion 6 moves through the interior of the sliding groove 12. Component 2 includes two bases 21 and a bidirectional lead screw 22. The two bases 21 are fixedly installed on the bottom surface of the pallet base 1 by bolts. One end of the bidirectional lead screw 22 is rotatably connected to the inside of the two bases 21. The transmission frame 3 includes a transmission block 31 and a transmission plate 32. The transmission plate 32 is fixedly connected to one side of the transmission block 31. Two sliders 4 are fixedly connected to both ends of the transmission plate 32. The bottom end of the support block 5 is provided with a groove 53. The end of the transmission plate 32 is located inside the groove 53. Several first guide grooves 41 are provided on the other side of the sliders 4. A guide bar 54 is fixedly connected to one side of the support block 5. A second guide groove 311 is provided on one side of the transmission block 31. The guide bar 54 is slidably connected inside the second guide groove 311. A long plate 13 is also fixedly installed in the middle of the bottom surface of the pallet base 1. The bidirectional lead screw 22 moves through the center of the long plate 13.

[0022] The specific settings and functions of this embodiment are described below. When it is necessary to adjust the position of the slider 4 according to the conveyor track of the conveyor line, the operator inserts one end of the adjusting rod into the inside of the circular groove 51, engages with the end of the transmission device 52, and drives the transmission device 52 to rotate. The transmission device 52 drives the bidirectional lead screw 22 to rotate, and the bidirectional lead screw 22 drives the two transmission frames 3 to move towards or away from each other. Under the transmission of the transmission frames 3, the two adjacent sliders 4 are driven to adjust their positions and align with the conveyor track of the conveyor line, so as to realize the telescopic adjustment to adapt to the adjustment of the conveyor line. At the same time, under the transmission of the transmission frames 3, the support protrusion 6 drives the second support frame 7 to perform the opposite or opposite adjustment operation, expand or shrink the holding space of the support frame, so that the pallet can be adjusted synchronously and flexibly according to the size of the goods conveyed by the conveyor line to meet the size requirements of different specifications of goods.

[0023] When the transmission frame 3 is adjusted by sliding, the guide bar 54 slides inside the second guide groove 311, constraining the movement trajectory of the transmission block 31 and preventing deviation. When the transmission block 31 drives the transmission plate 32 to adjust by sliding, the end of the transmission plate 32 moves inside the groove 53. By opening the groove 53 at the bottom of the support block 5, it is ensured that the support block 5 will not interfere with the transmission plate 32 in space when the transmission plate 32 moves.

[0024] Example 2: Figures 1-6 As shown, the telescopic pallet device for the conveyor line in this utility model includes a pallet base 1. An adjustment component 2 is fixedly installed in the middle of the bottom surface of the pallet base 1. A transmission frame 3 is connected to the driving end of the adjustment component 2. Slider 4 is fixedly connected to both ends of one side of the transmission frame 3. Support blocks 5 are fixedly connected to the bottom surface of the pallet base 1 in a symmetrical manner. A circular groove 51 is opened inside the support block 5. A transmission device 52 is rotatably connected inside the circular groove 51. The other end of the transmission device 52 is connected to the outside of the driving end of the adjustment component 2. A support frame 11 is fixedly connected to the center of the top surface of the pallet base 1. A sliding groove 12 is symmetrically opened on the top surface of the pallet base 1. The other side of the transmission frame 3 is fixedly connected to... There is a supporting protrusion 6, one end of which is fixedly connected to a second supporting frame 7. The supporting protrusion 6 movably passes through the interior of the slide groove 12. The adjusting component 2 includes two bases 21 and a bidirectional lead screw 22. The two bases 21 are fixedly installed on the bottom surface of the tray base 1 by bolts. One end of the bidirectional lead screw 22 is rotatably connected to the interior of the two bases 21 respectively. The transmission device 52 includes a transmission rod 521 and a first bevel gear 522. The first bevel gear 522 is fixedly connected to one end of the transmission rod 521. A second bevel gear 523 meshes with the outside of the first bevel gear 522. The second bevel gear 523 is fixedly installed on the outside of the bidirectional lead screw 22. A rectangular positioning groove 524 is opened at the other end of the transmission rod 521.

[0025] The overall effect of this embodiment is that when the operator uses the adjusting rod to drive the transmission 52 to rotate, the rectangular protrusion at the end of the adjusting rod needs to be aligned with the rectangular positioning groove 524, and then the rectangular protrusion is engaged inside the rectangular positioning groove 524. Under the transmission of the transmission rod 521, the first bevel gear 522 is driven to rotate, and under the transmission of the second bevel gear 523, the bidirectional lead screw 22 is driven to rotate, thereby driving the two transmission frames 3 to move towards or away from each other. When it is not necessary to adjust the position of the slider 4 in the tray, the adjusting end of the transmission 52 is located inside the circular groove 51, which does not occupy the external space of the tray and avoids the end of the transmission 52 from colliding with hard objects in the external environment.

[0026] The operation and working principle of this device are as follows: The operator inserts one end of the adjusting rod into the inside of the circular groove 51, engages it with the end of the transmission device 52, and drives the transmission device 52 to rotate. The transmission device 52 drives the bidirectional lead screw 22 to rotate, and the bidirectional lead screw 22 drives the two transmission frames 3 to move towards or away from each other. Under the transmission of the transmission frames 3, the two adjacent sliders 4 are driven to adjust their positions and align with the conveyor track of the conveyor line, so as to realize the telescopic adjustment to adapt to the adjustment of the conveyor line. At the same time, under the transmission of the transmission frames 3, the support protrusion 6 drives the second support frame 7 to perform the adjustment operation of facing towards or away from each other, expanding or shrinking the holding space of the support frame.

[0027] When the transmission frame 3 is adjusted by sliding, the guide bar 54 slides inside the second guide groove 311, constraining the movement trajectory of the transmission block 31 and preventing deviation. When the transmission block 31 drives the transmission plate 32 to adjust by sliding, the end of the transmission plate 32 moves inside the groove 53. By opening the groove 53 at the bottom of the support block 5, it is ensured that the support block 5 will not interfere with the transmission plate 32 in space when the transmission plate 32 moves.
