[0023] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0024] Reference Figure 1 , Figure 2 and Figure 5 This embodiment provides a trolley connecting device, including a connector 1. The connector 1 effectively mounts the entire device onto the bottom of the trolley. A travel fixing bolt 2 is provided on the connector 1, effectively fixing the connector 1 together. A bearing wheel 3 is mounted on one side of the device, with the bearing wheel 3 connected to the end of the travel fixing bolt 2. The bearing wheel 3 facilitates better transport of the trolley on the conveyor belt. A connecting shaft 4 is provided on the connector 1, cooperating with the travel fixing bolt 2. The cooperation between the travel fixing bolt 2 and the connecting shaft 4 effectively fixes the connector 1. Together, the bottom of the connector 1 is equipped with a guide wheel 6, which effectively limits the movement of the trolley and prevents it from deviating during movement. The travel fixing bolt 2 and the connecting shaft 4 are movably mounted with a connector 7. The connector 7 allows the existing logistics trolleys to be connected by a chain or by a hydraulic cylinder and a connector head, making the connection methods between the trolleys more diversified. Different connection devices can be selected according to the drive mode of different sorting machines, ensuring that the distance between the trolleys will not be affected during long-term use, and avoiding the phenomena of decreased accuracy, chain aging, and breakage.

[0025] Both the traveling fixing bolt 2 and the connecting shaft 4 pass through the connecting piece 1, and both the traveling fixing bolt 2 and the connecting shaft 4 are provided with fixing pieces 5 at their top ends. By setting the fixing pieces 5, the traveling fixing bolt 2 and the connecting shaft 4 are effectively fixed on the connecting piece 1, and the bearing wheel 3 is also effectively limited to prevent the bearing wheel 3 from shifting during movement.

[0026] In use, firstly, screws are passed through the connector 1 and the trolley to symmetrically fix the connector 1 on both sides of the trolley. Next, the travel fixing bolt 2 is passed through the connector 1 and the connecting piece 7 in sequence. The bearing wheel 3 is installed on one side of the trolley. Then, the connecting shaft 4 is passed through the connector 1. Then, the travel fixing bolt 2 and the connecting shaft 4 are fixed to the connector 1 by the fixing piece 5 to prevent the bearing wheel 3 from shifting during use, and also to prevent the travel fixing bolt 2 and the connecting shaft 4 from falling off the connector 1. Finally, the travel fixing bolt 2 and the connecting shaft 4 are connected by the connecting piece 7 to achieve the connection and fixation effect between the trolleys.

[0027] In summary, the beneficial effects of this utility model are as follows: by setting the connecting parts, the existing logistics carts can be connected by chains or by the cooperation between hydraulic cylinders and connectors, making the connection methods between carts more diversified. Different connection devices can be selected according to the driving methods of different sorting machines, ensuring that the distance between carts will not be affected during long-term use, and avoiding the phenomena of decreased precision, chain aging, and breakage.

[0028] Reference Figure 3 In one embodiment provided in this application, the connector 1 includes a first connecting plate 11 and a second connecting plate 13, which are interleaved. The cooperation between the first connecting plate 11 and the second connecting plate 13 can effectively ensure the installation of the support plate 3.

[0029] Furthermore, the first connecting plate 11 has connecting holes 12 that penetrate through it, and multiple connecting holes 12 are provided. The connecting holes 12 facilitate the insertion of screws through the first connecting plate 11, fixing it to both sides of the trolley. Limiting holes 14 are provided at the intersection of the first connecting plate 11 and the second connecting plate 13, facilitating the insertion of the connecting piece 7 and allowing for better connection between the connecting piece 7 and the connecting shaft 4.

[0030] In use, firstly, the first connecting plate 11 is fixed to both sides of the trolley through the connecting hole 12. Then, the first connecting plate 11 and the second connecting plate 13 are fitted together and staggered to facilitate the passage of the travel fixing bolt 2 and the connecting shaft 4. After the first connecting plate 11 and the second connecting plate 13 are fixed, the connecting piece 7 can better pass through the limiting hole 14 and connect with the connecting shaft 4.

[0031] Reference Figure 3In some embodiments, the fastener 5 includes an anti-loosening washer 51 nested on the travel fixing bolt 2 and the connecting shaft 4. The anti-loosening washer 51 reduces the likelihood of screw loosening due to machine vibration later on. A fixing nut 52 is movably mounted on the outer side of the anti-loosening washer 51, and a positioning rod 53 is provided on one side of the fixing nut 52. The positioning rod 53 passes through the travel fixing bolt 2 and the connecting shaft 4. Through the cooperation between the fixing nut 52 and the positioning rod 53, the travel fixing bolt 2 and the connecting shaft 4 can be effectively fixed to the connecting element 1.

[0032] Reference Figure 4 As an optional embodiment, the connecting member 7 includes a hydraulic cylinder 71. The hydraulic cylinder 71 can be adjusted in length to adapt to the length of the trolley, providing better adaptability. During operation, the distance between trolleys can be adjusted automatically, making it more convenient to use. The two ends of the hydraulic cylinder 71 are respectively provided with a first connector 72 and a second connector 73. Through the cooperation between the first connector 72 and the second connector 73, the two ends of the hydraulic cylinder 71 are effectively connected to the travel fixing bolt 2 and the connecting shaft 4, respectively. The outer sides of the first connector 72 and the second connector 73 are provided with placement grooves 74. The inner walls of the placement grooves 74 are provided with positioning holes 75 on both sides, and the positioning holes 75 penetrate the first connector 72 and the second connector 73. The travel fixing bolt 2 and the connecting shaft 4 are both connected to the hydraulic cylinder 71 through the positioning holes 75.

[0033] Reference Figure 5 and Figure 6 As an optional embodiment, the connector 7 also includes a chain 76, which is connected to the connector 1 via the fastener 5. The chain 76 effectively connects the connecting travel fixed shaft bolt 2 to the connector 1.

[0034] When the sorting machine is driven by a geared motor, a conventional chain 76 can be used to connect the walking fixed shaft bolt 2 for the sorting machine connection and transmission.

[0035] When the sorting machine is driven by a linear motor, the trolley can be equipped with a travel fixing bolt 2 for connection and transmission, and is equipped with an anti-loosening washer 51. At the same time, the micro hydraulic cylinder 71 can extend and retract autonomously, and is not affected by the running speed, which greatly improves the safety performance.

[0036] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
