[0067] Referring to Figure 2The lock 21 comprises a lock rod 211, a lock tongue 212 and a handle 213. The lock rod 211 is rotationally connected to the end frame 12. The lock tongue 212 is arranged at one end of the lock rod 211 close to the side frame 13, and the lock tongue 212 is arranged at an angle with the lock rod 211. The handle 213 is arranged at the other end of the lock rod 211 away from the lock tongue 212, and can drive the lock 21 to rotate around the axis of the lock rod 211. The limiting plate 22 is arranged on both sides of the side frame 13 and protrudes towards the end frame 12. The fixing portion 23 is arranged on the end frame 12 and cooperates with the handle 213 to limit the handle 213.

[0068] Specifically, the lock 21 is arranged on the end frame upper beam 121. The lock 21 is composed of a cylindrical metal, and both ends thereof are bent downward to form the lock tongue 212 and the handle 213. The limiting plate 22 is fixed above the side of the second upright 132 of the side frame 13 and is arranged opposite to the lock tongue 212.

[0069] When the handle 213 of the lock 21 is limited on the fixing portion 23 of the end frame 12, the lock tongue 212 hooks the limiting plate 22 to abut the limiting plate 22 on the side of the end frame 12. At this time, the lock 21 is limited by the fixing portion 23, preventing the movement of the lock 21, and realizing the connection and fixation between the side frame 13 and the end frame 12.

[0070] When the handle 213 rotates around the axis of the lock rod 211 away from the fixing portion 23, the lock tongue 212 rotates with the lock rod 211 and moves away from the limiting plate 22, thereby disengaging the abutting limiting of the limiting plate 22, to release the locking of the top of the side frame 13 and the end frame 12, so that the side frame 13 can be detached from the second mounting space of the bottom plate 113.

[0071] The lock device 20 in the embodiment can quickly realize the locking and unlocking of the side frame 13 and the end frame 12, and has simple manufacturing process, reliable locking function and can realize the quick connection and disassembly of the side frame 13 and the end frame 12 through simple actions.

The lock rod 211 is fixed by the lock sleeve 214, which has a simple structure. During installation, the lock rod 211 is arranged in the lock sleeve 214, and then the lock sleeve 214 is welded to the top surface of the end frame 12, so that the lock 21 and the end frame 12 are fixed.

[0076] Please refer to Figure 4 、 Figure 15 、 Figure 16 and Figure 20 In the embodiment, the tray box 100 further comprises a water guide assembly 30, which comprises a water collector 31 and a water guide channel 32. The water collector 31 is located below the installation gap between the end frame upper beam 121 and the side frame upper beam 131, and is used to collect water flowing into the accommodation cavity of the tray box 100 from the installation gap between the end frame upper beam 121 and the side frame upper beam 131, so as to increase the sealing performance of the tray box 100.

[0077] Please refer to Figure 15 and Figure 16 The internal structure of the water collector 31 forms a water collecting cavity, and the end frame upper beam 121 and the side frame upper beam 131 abut each other when penetrating into the water collecting cavity of the water collector 31. Therefore, the water flowing along the sides of the end frame upper beam 121 and the side frame upper beam 131 is collected by the water collector 31 and cannot enter the accommodation cavity of the main body of the tray box 100 to wet the goods. This effectively solves the problem that the gap at the abutting position of the side frame upper beam 131 and the end frame upper beam 121 can allow water to enter, which can damage the goods in the tray box 100. This effectively improves the waterproof sealing performance of the connection position of the end frame 12 and the side frame 13 of the tray box 100, so that the tray box 100 is more safe and reliable during transportation of goods.

[0078] Specifically, as shown in Figure 16 The side wall of the water collector 31 is provided with a first connecting port 311, a second connecting port 312 and a third connecting port 313 which are connected with the water collecting cavity. The first connecting port 311 is matched with the upper beam 121 of the end frame, so that the upper beam 121 of the end frame and the upper beam 131 of the side frame pass through the first connecting port 311 into the water collecting cavity. The second connecting port 312 is matched with the upper beam 131 of the side frame, so that the upper beam 131 of the side frame passes through the second connecting port 312 into the water collecting cavity and abuts against the upper beam 121 of the end frame in the water collector 31. The third connecting port 313 is connected with the water guide channel 32, so that the liquid entering the water collector 31 from the gap between the upper beam 121 of the end frame and the upper beam 131 of the side frame can flow out along the water guide channel 32 connected with the third connecting port 313.

[0079] Further, the first connecting port 311 in the embodiment includes a first vertical surface 3111 and a second vertical surface 3112 which intersect with each other. When the upper beam 121 of the end frame passes through the first connecting port 311, the first wall plate 1211 of the upper beam 121 of the end frame completely abuts against the first vertical surface 3111, and the second wall plate 1212 of the upper beam 121 of the end frame completely abuts against the second vertical surface 3112, i.e., the outer contour of the upper beam 121 of the end frame completely matches the vertical surface of the first connecting port 311.

[0080] Correspondingly, the second connecting port 312 includes a third vertical surface 3121 and a fourth vertical surface 3122. When the side frame 13 is connected with the end frame 12, the third wall plate 1311 of the upper beam 131 of the side frame completely abuts against the third vertical surface 3121 of the second connecting port 312, and the fourth wall plate 1312 completely abuts against the fourth vertical surface 3122 of the second connecting port 312, i.e., the outer contour of the upper beam 131 of the side frame completely matches the vertical surface of the second connecting port 312.

[0081] The water collector 31 matches the contour of the upper beam 121 of the end frame and the upper beam 131 of the side frame, so that the liquid entering the water collecting cavity can be prevented from entering the main body of the tray box 100 through the gap at the connecting position of the water collector 31 with the upper beam 121 of the end frame and the upper beam 131 of the side frame, thereby enhancing the waterproof capability of the water collector 31.

[0082] It should be understood that the water collector 31 in the embodiment is fixed on the inner side of the end frame 12 and is welded with the first vertical column 122 of the end frame 12. By adopting this arrangement, the end frame 12 and the side frame 13 can be conveniently assembled and connected.

[0083] In some other embodiments, the water collector 31 can also be fixed on the inner side of the side frame 13, as long as the water collecting cavity of the water collector 31 is located below the upper horizontal beam 121 of the end frame 12 and the upper horizontal beam 131 of the side frame 13 after the end frame 12 and the side frame 13 are connected, so that the water can flow into the water collector 31 through the gap between the upper horizontal beam 121 of the end frame 12 and the upper horizontal beam 131 of the side frame 13 and be discharged.

[0084] Referring to Figure 16 In some embodiments, the bottom of the water collector 31 is gradually inclined towards the third connecting port 313. Specifically, the bottom of the water collecting cavity of the water collector 31 is composed of two plate bodies 1131, both of which are inclined towards the third connecting port 313, so that the water in the water collector 31 can be quickly discharged and not accumulated.

[0085] Referring to Figure 14 In some embodiments, the water guide channel 32 includes a first flow guide part 321, which is arranged on the inner side of the end frame 12 and extends along the height direction of the end frame 12. The first flow guide part 321 is recessed inward towards the side of the side frame 13 to form a flow guide groove, which is in communication with the water collector 31, so that the liquid in the water collector 31 can be discharged along the flow guide groove.

[0086] Specifically, as Figure 15 shown, the first flow guide part 321 and the water collector 31 of the present embodiment are both fixed on the inner side of the first vertical column 122 of the end frame 12, and the flow guide groove formed by the first flow guide part 321 is in sequence with the third connecting port 313 of the water collector 31, so that the water on the water collector 31 can quickly flow out along the flow guide groove of the first flow guide part 321 and not be accumulated.

[0087] Referring to Figure 18 and Figure 19 In some embodiments, the water guide channel 32 further includes a second flow guide part 322. The second flow guide part 322 is arranged on the inner side of the side frame 13 and extends along the height direction of the side frame 13. The second flow guide part 322 is recessed inward towards the side of the first flow guide part 321 to form a receiving groove.

[0088] When the end frame 12 and the side frame 13 are connected, one side wall of the second flow guide part 322 is accommodated in the flow guide groove of the first flow guide part 321, and one side wall of the first flow guide part 321 is accommodated in the receiving groove of the second flow guide part 322, so as to form an interlaced channel.

[0089] Specifically, as Figure 15As shown, the first flow guide part 321 includes a first bottom wall 3211 and a first side wall 3212. The first bottom wall 3211 is fixed on the inner side of the first upright column 122 of the end frame 12, and the first side wall 3212 is connected to the first bottom wall 3211, so that the first side wall 3212, the first bottom wall 3211, and the inner side wall of the first upright column 122 of the end frame 12 form a flow guide groove.

[0090] As shown, Figure 20 the second flow guide part 322 includes a second side wall 3221 and a third side wall 3222, which are arranged on the inner side of the second upright column 132 of the side frame 13. The second side wall 3221 and the third side wall 3222 form a receiving groove with the inner side wall of the second upright column 132 of the side frame 13.

[0091] When the end frame 12 abuts against the side frame 13, the first side wall 3212 of the first flow guide part 321 is received in the receiving groove of the second flow guide part 322, and the second side wall 3221 of the second flow guide part 322 near the end frame 12 is received in the flow guide groove of the first flow guide part 321, so that the abutting part of the end frame 12 and the side frame 13 forms an interlaced waterproof channel, preventing liquid from entering the tray box 100.

[0092] The first side wall 3212 of the first flow guide part 321 on the end frame 12 and the second side wall 3221 of the second flow guide part 322 on the side frame 13 are spaced apart and cooperated to form a labyrinth waterproof structure, so that the connection part of the end frame 12 and the side frame 13 is not easy to enter water, which can effectively improve the sealing performance of the tray box 100.

[0093] Please refer to Figure 19 , Figure 20 and Figure 4 , the water blocking blocks 134 are provided on both sides of the fourth wall of the side frame upper cross beam 131 and protrude towards the inside of the tray box 100. When the side frame upper cross beam 131 passes through the second connecting port 312 and abuts against the end frame upper cross beam 121; the water blocking blocks 134 are located in the water collecting cavity of the water collector 31. The water blocking blocks 134 in the water collector 31 are also the water collecting cavity of the water collector 31, which forms a waterproof labyrinth to prevent liquid from dripping towards the inside of the main body of the tray box 100, further increasing the sealing performance of the tray box 100.

[0094] In some embodiments, please refer to Figure 11 and Figure 17 , the guide limiting members 125 are protruded on the end frame upper cross beam 121 and the side frame upper cross beam 131. The guide limiting members 125 are inclinedly arranged towards the inner side of the main body of the tray box 100, and the guide limiting members 125 are narrow at the top and wide at the bottom; so as to guide the top cover 14, so that the top cover 14 can be quickly covered on the main body of the tray box 100.
