[0035] Such as Figure 1 and Figure 2As shown in the figure, this embodiment provides a connecting component 1 for connecting a first rack and a second rack. The connecting component 1 includes a support base 11, a screw 12, a support shaft 13, and a first fastener 14. Among them, the support base 11 is used to connect with the first rack. The first end of the screw 12 is threadedly connected to the support base 11. The support shaft 13 is used to connect with the second rack. The support shaft 13 is provided with a first threaded hole 131, a support surface 132, a first milled plane 133, and a second threaded hole 134. The first threaded hole 131 is threadedly connected to the second end of the screw 12. The support surface 132 is perpendicular to the axis of the first threaded hole 131. The support surface 132 is used to abut against the second rack. The first milled plane 133 is perpendicularly connected to the support surface 132. The first milled plane 133 is used to fit with the surface of the second rack. The second threaded hole 134 vertically penetrates the first milled plane 133. The first fastener 14 is used to pass through the second rack and be threadedly connected to the second threaded hole 134. The support shaft 13 in the connecting component 1 provided in this embodiment is provided with a support surface 132 and a first milled plane 133. When the connecting component 1 is connected between the first rack and the second rack, the support base 11 is connected to the first rack, the support surface 132 abuts against the second rack, the first milled plane 133 fits with the surface of the second rack, and the first fastener 14 passes through the second rack and is threadedly connected to the second threaded hole 134, so as to realize the fixed connection between the support shaft 13 and the second rack. The connecting component 1 provided in this embodiment realizes the positioning and connection with the second rack by using the part of the support shaft 13, with a simple structure, which is conducive to assembly and cost reduction. In addition, when the screw 12 is rotated, by adjusting the depth of the screw 12 screwed into the support shaft 13, the position of the second rack relative to the first rack can also be adjusted.

[0036] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, the support shaft 13 is further provided with a second milled plane 135. The second milled plane 135 is arranged in parallel and spaced from the first milled plane 133. The second threaded hole 134 vertically penetrates the first milled plane 133 and the second milled plane 135. The first fastener 14 includes a first bolt 141 and a first nut 142. After the first bolt 141 is threadedly connected to the second threaded hole 134, it passes through the second rack and is threadedly connected to the first nut 142. By providing the second milled plane 135, the contact area between the first fastener 14 and the support shaft 13 is increased, thereby ensuring the reliable connection between the first bolt 141 and the support shaft 13 and the second rack. Optionally, in this embodiment, a second through hole 302 is opened on the second rack. After the first bolt 141 is threadedly connected to the second threaded hole 134, it passes through the second through hole 302 on the second rack and is threadedly connected to the first nut 142.

[0037] In this embodiment, as Figure 1 and Figure 2As shown in the figure, the support base 11 includes a support plate 111, a shock pad 112, and a second fastener 113. Among them, the shock pad 112 is threadedly connected to the first end of the screw 12, and the second fastener 113 passes through the shock pad 112 and is threadedly connected to the support plate 111. The structural design of the above support base 11 enables the connection assembly 1 to also have a shock-absorbing function. The device using the connection assembly 1 in this embodiment can reduce the amplitude of the device to improve the service life of the device. Optionally, in this embodiment, the shock pad 112 is a bowl-shaped shock pad. Optionally, the support base 11 includes two second fasteners 113, and the two second fasteners 113 together realize the connection between the shock pad 112 and the support plate 111. Specifically, the bowl-shaped shock pad is provided with a central threaded hole 101 and two first through holes 102. The central threaded hole 101 is threadedly connected to the first end of the screw 12. The two first through holes 102 are symmetrically arranged with respect to the central threaded hole 101. The support plate 111 is correspondingly provided with two third threaded holes 103. The second fastener 113 includes a second bolt 104 and a second nut 105. The two second bolts 104 respectively pass through the corresponding first through holes 102, are threadedly connected to the corresponding third threaded holes 103, and then are connected to the corresponding second nuts 105.

[0038] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, a limiting groove 301 is provided at the edge of the second frame. The support shaft 13 extends into the limiting groove 301. The width of the limiting groove 301 matches the diameter of the support shaft 13. The supporting surface 132 of the support shaft 13 abuts against the edge of the limiting groove 301, thereby restricting the relative position of the support shaft 13 and the second frame in the width direction of the limiting groove 301.

[0039] In this embodiment, as Figure 1 and Figure 2As shown, the connecting component 1 further includes a first limiting nut 15 and a second limiting nut 16. Both the first limiting nut 15 and the second limiting nut 16 are threadedly connected to the screw rod 12. The first limiting nut 15 abuts against the end face of the support shaft 13, and the second limiting nut 16 abuts against the first limiting nut 15. The second limiting nut 16 can prevent the first limiting nut 15 from loosening, so that the position of the first limiting nut 15 is fixed. Furthermore, the relative position between the screw rod 12 and the support shaft 13 is fixed, thereby realizing a reliable connection. Optionally, the connecting component 1 further includes a third limiting nut 17. The third limiting nut 17 is also threadedly connected to the screw rod 12 and abuts against the shock pad 112 in the support base 11, thereby limiting the relative position between the support shaft 13 and the support base 11. Optionally, in other embodiments, multiple limiting nuts can be provided. The specific number of limiting nuts can be adjusted as needed, as long as it is ensured that the multiple limiting nuts are arranged in sequence and abut against each other along the axial direction of the screw rod 12. Each limiting nut is threadedly connected to the screw rod 12, and one of the limiting nuts located on the outside abuts against the support shaft 13, and the other limiting nut located on the outside abuts against the shock pad 112 in the support base 11, so as to limit the relative position between the support shaft 13 and the support base 11 by using the multiple limiting nuts.

[0040] As Figures 3 to 8 shown, this embodiment also provides a linear sorting machine. The linear sorting machine includes a gantry 2, a linear track 3, a sorting trolley 4, and the above-mentioned connecting component 1. The linear track 3 is used to support the sorting trolley 4. The gantry 2 is the first frame, the linear track 3 is the second frame, and the connecting component 1 is used to connect the gantry 2 and the linear track 3. Since the linear sorting machine provided in this embodiment uses the above-mentioned connecting component 1 to connect the linear track 3 and the gantry 2, the cost is reduced and the assembly efficiency is improved.

[0041] Specifically, as Figure 3 and Figure 4 shown, the linear sorting machine includes at least two gantries 2. The at least two gantries 2 are arranged at intervals in the first direction (the left-right direction in the figure). The linear sorting machine further includes two arc tracks 5. The linear track 3 includes an upper linear track 31 and a lower linear track 32 arranged at intervals in the up-down direction. Both the upper linear track 31 and the lower linear track 32 extend in the first direction. The two arc tracks 5 are arranged at intervals in the first direction. The upper ends of the two arc tracks 5 are respectively connected to the two ends of the upper linear track 31, and the lower ends of the two arc tracks 5 are respectively connected to the two ends of the lower linear track 32. Optionally, in this embodiment, at least one of the upper linear track 31 and the lower linear track 32 is connected to the gantry 2 through the above-mentioned connecting component 1.

[0042] In this embodiment, as Figure 4As shown, each gantry 2 includes an upper crossbeam 21 and a lower crossbeam 22 that are spaced apart in the vertical direction. The upper linear track 31 is located above the upper crossbeam 21. Two connecting components 1 are arranged at intervals along the second direction (the front-back direction in the figure) on each upper crossbeam 21. The support base 11 of each connecting component 1 is located above the corresponding upper crossbeam 21 and is supported by the corresponding upper crossbeam 21. And the support shaft 13 of each connecting component 1 is connected to the upper linear track 31 through a first fastener 14. Among them, the first direction and the second direction are arranged at an angle. In this embodiment, when the connecting component 1 realizes the connection between the upper crossbeam 21 and the upper linear track 31, the support plate 111 is placed on the upper crossbeam 21, ensuring the contact area between the support base 11 and the upper crossbeam 21. The support surface 132 of the support shaft 13 abuts against the upper linear track 31, making the support for the upper linear track 31 more stable. In addition, by adjusting the depth of the adjusting screw 12 screwed into the support shaft 13, the height of the upper linear track 31 can also be adjusted.

[0043] Optionally, in this embodiment, as Figure 4 shown, each gantry 2 further includes two columns 23. The two columns 23 are spaced apart along the second direction. Each column 23 extends in the vertical direction. The upper crossbeam 21 and the lower crossbeam 22 are both connected between the two columns 23, thus ensuring the structural stability of the entire gantry 2. Optionally, the upper crossbeam 21, the lower crossbeam 22, and the columns 23 are all square tube structures.

[0044] Optionally, in this embodiment, as Figure 5 shown, the upper linear track 31 includes two upper slide rails 311 that are opposite and spaced apart along the second direction and an upper connecting plate 312 connected between the two upper slide rails 311. Each upper slide rail 311 extends in the first direction. When the connecting component 1 connects the upper crossbeam 21 and the upper linear track 31, the lower edge of the upper connecting plate 312 abuts against the support surface 132, and the first milling plane 133 fits against the plate surface of the upper connecting plate 312. The first fastener 14 passes through the upper connecting plate 312 and is threadedly connected to the second threaded hole 134, so that the support shaft 13 reliably supports the upper linear track 31. Optionally, a limiting groove 301 is provided at the lower edge of the upper connecting plate 312. When the connecting component 1 connects the upper crossbeam 21 and the upper linear track 31, the support shaft 13 extends into the limiting groove 301. The width of the limiting groove 301 matches the diameter of the support shaft 13, and the support surface 132 of the support shaft 13 abuts against the upper edge of the limiting groove 301, thereby restricting the relative position of the support shaft 13 and the upper connecting plate 312 along the second direction.

[0045] Optionally, referring to Figures 3 to 5As shown, the sorting trolley 4 includes two sets of running wheels 41 arranged at intervals in the second direction. The two sets of running wheels 41 can be respectively supported by two upper slide rails 311 and roll along the upper slide rails 311. In the up-down direction, the two upper slide rails 311 are respectively located above the two connecting components 1. With the above arrangement, the two upper slide rails 311 are both supported on the upper cross beam 21 through a connecting component 1, so that the sorting trolley 4 can be supported more stably.

[0046] Optionally, as Figure 5 shown, the upper linear track 31 includes two upper connecting plates 312. Each upper slide rail 311 includes a first end and a second end arranged in the first direction. One upper connecting plate 312 is connected between the first ends of the two upper slide rails 311, and the other upper connecting plate 312 is connected between the second ends of the two upper slide rails 311. Optionally, the linear track 3 includes a plurality of upper linear tracks 31 arranged in sequence in the first direction. Two adjacent upper linear tracks 31 share the same upper connecting plate 312 and two connecting components 1, which reduces the cost. Optionally, in this embodiment, the upper linear track 31 further includes a netting 314. A netting 314 is connected between the two upper slide rails 311 and between the two upper connecting plates 312. The netting 314 is located below the upper linear track 31 and is used to catch the items accidentally dropped by the sorting trolley 4 on the upper linear track 31, so as to prevent the items from falling onto the sorting trolley 4 on the lower linear track 32 and affecting its movement. Optionally, the upper linear track 31 further includes six first reinforcing beams 313. Four of the first reinforcing beams 313 are connected in a rectangle, and the four first reinforcing beams 313 are respectively connected to the two upper slide rails 311 and the two upper connecting plates 312 in a one-to-one correspondence. The other two first reinforcing beams 313 are both connected between the two upper slide rails 311, thereby strengthening the structural strength of the upper linear track 31.

[0047] Optionally, in this embodiment, as Figure 4 shown, the lower linear track 32 is located below the lower cross beam 22. Two connecting components 1 are arranged at intervals in the second direction on each lower cross beam 22. The support base 11 of each connecting component 1 is located above the lower cross beam 22 and is supported by the lower cross beam 22. The support shaft 13 of each connecting component 1 is connected to the lower linear track 32 through a first fastener 14. Optionally, in other embodiments, the lower linear track 32 can also be located above the lower cross beam 22, and the connection manner of the connecting component 1 to the lower linear track 32 is the same as the connection manner of the connecting component 1 to the upper linear track 31.

[0048] Optionally, in this embodiment, as Figures 6 to 8As shown in the figure, the lower linear track 32 includes two lower slide rails 321 that are opposite and spaced apart in the second direction, and a lower connecting plate 322 connected between the two lower slide rails 321. Each lower slide rail 321 extends in the first direction. When the connecting assembly 1 connects the lower linear track 32 and the lower cross beam 22, the supporting surface 132 abuts against the upper edge of the lower connecting plate 322, the first milled plane 133 fits against the plate surface of the lower connecting plate 322, and the first fastener 14 passes through the lower connecting plate 322 and is threadedly connected to the second threaded hole 134. It should be noted that a second through hole 302 is formed in the lower connecting plate 322. When connecting the lower connecting plate 322 and the support shaft 13, after the supporting surface 132 abuts against the upper edge of the lower connecting plate 322, the first fastener 14 is passed through the second through hole 302 in the lower connecting plate 322 and threadedly connected to the second threaded hole 134, so that the lower connecting plate 322 and the support shaft 13 can be quickly positioned. Optionally, a limiting groove 301 is provided at the upper edge of the lower connecting plate 322. When the connecting assembly 1 connects the lower linear track 32 and the lower cross beam 22, the support shaft 13 extends into the limiting groove 301. The width of the limiting groove 301 matches the diameter of the support shaft 13, and the supporting surface 132 of the support shaft 13 abuts against the lower edge of the limiting groove 301, thereby restricting the relative position of the support shaft 13 and the lower connecting plate 322 in the second direction.

[0049] Optionally, in this embodiment, as Figure 6 shown, the lower linear track 32 includes two lower connecting plates 322. One lower connecting plate 322 is connected between the first ends of the two lower slide rails 321, and the other lower connecting plate 322 is connected between the second ends of the two lower slide rails 321. Optionally, the linear track 3 includes a plurality of lower linear tracks 32, and the plurality of lower linear tracks 32 are arranged in sequence in the first direction. Two adjacent lower linear tracks 32 share the same lower connecting plate 322 and two connecting assemblies 1, which reduces the cost. Optionally, in this embodiment, the lower linear track 32 further includes a lower sealing plate 325. A lower sealing plate 325 is connected between the two lower slide rails 321 and between the two lower connecting plates 322, and the lower sealing plate 325 is located above the lower linear track 32. Optionally, the lower linear track 32 further includes a second reinforcing beam 323, and a second reinforcing beam 323 is correspondingly connected to each of the two lower slide rails 321, thereby strengthening the structural strength of the lower linear track 32.
