[0030] Please refer to Figures 1 to 7, the present invention provides a logistics storage cage, including a storage cage 1 for storing items. Inside the storage cage 1, there is a classification box 3 for placing items in categories. On the top of the storage cage 1, there is a handling mechanism 2 that facilitates stacking work. On the classification box 3, there is a taking mechanism 4 that facilitates taking the items inside. And the taking mechanism 4 is connected to the handling mechanism 2. Through the handling mechanism 2, stacking work can be facilitated, saving a lot of effort for the staff and improving work efficiency. Through the classification box 3, items can be stored in categories, and then the classification box 3 is slid into the inside of the storage cage 1 for storage. By connecting the taking mechanism 4 and the handling mechanism 2, the sealing of the classification box 3 can be maintained, and at the same time, items can be conveniently stored and retrieved through the taking mechanism 4.

[0031] As Figure 4 shown, both the top of the storage cage 1 and the side where the classification box 3 slides in are designed with through grooves, which can facilitate the classification box 3 to slide into the inside of the storage cage 1 for storage.

[0032] As Figure 4 shown, at least two classification boxes 3 are placed inside the storage cage 1. And the outer side of the end where the classification box 3 first slides into the inside of the storage cage 1 is in contact with the inner wall of the storage cage 1. The outer side of the classification box 3 is in contact with the inner wall of the storage cage 1, which can improve the stability of the classification box 3 inside the storage cage 1.

[0033] As Figure 2 , Figure 3 shown, the handling mechanism 2 includes a fixed seat 23. Four fixed seats 23 are fixedly assembled at the top corners of the storage cage 1. The cross-section of the fixed seat 23 is L-shaped. Inside the fixed seat 23, a first telescopic spring 210 is fixedly installed. The other end of the first telescopic spring 210 is fixedly installed with a closing plate 21. By having four fixed seats 23 fixedly assembled at the top corners of the storage cage 1, when the closing plate 21 slides, the closing plate 21 can be restricted to prevent displacement during sliding and affecting the work.

[0034] As Figure 2 , Figure 3 shown, at the corner of the side of the closing plate 21 away from the first telescopic spring 210, a driving rod 29 is fixedly installed. The end of the driving rod 29 away from the closing plate 21 is fixedly installed with a pressing plate 22. Both the pressing plate 22 and the closing plate 21 slide inside the fixed seat 23, and the pressing plate 22 and the closing plate 21 are located above the storage cage 1. Thus, when the pressing plate 22 slides, the pressing plate 22 can drive the closing plate 21 to slide through the driving rod 29, causing the closing plate 21 and the pressing plate 22 to slide inside the fixed seat 23.

[0035] As Figure 4As shown in the figure, a plug-in slot 211 is provided on the side of the closing plate 21 close to the storage cage 1. The plug-in slot 211 is movably plugged with the storage cage 1 and the sorting box 3. When the closing plate 21 slides to a certain position, the plug-in slot 211 on the closing plate 21 will be plugged with the storage cage 1 and the sorting box 3.

[0036] As Figure 2 , Figure 3 shown in the figure, a limiting slot 25 is provided on the side of the closing plate 21 away from the storage cage 1. A slider 26 is slidably installed inside the limiting slot 25. A rotating shaft 27 is rotatably installed through the slider 26. A connecting plate 24 is fixedly installed on the outer side of the rotating shaft 27. The connecting plate 24 slides at the middle position between the closing plate 21 and the pressing plate 22. And a pulley 28 is rotatably installed on the surface of the connecting plate 24. Pull the connecting plate 24, and the connecting plate 24 drives the slider 26 to move through the rotating shaft 27. The slider 26 slides inside the limiting slot 25. Thus, the connecting plate 24 will slide out of the middle position between the closing plate 21 and the pressing plate 22. After the connecting plate 24 slides out to a certain position, rotate the connecting plate 24 through the rotating shaft 27 so that one end of the connecting plate 24 contacts the ground. Thus, both ends of the connecting plate 24 are respectively connected to the pressing plate 22 and the ground. Through the pulley 28 on the surface of the connecting plate 24, it is convenient for another storage cage 1 to move on the connecting plate 24, so that another storage cage 1 is stacked on the surface of the pressing plate 22. Thus, a large amount of effort of the staff can be saved, the work is facilitated, and the work efficiency is improved.

[0037] As Figure 4 , Figure 5 , Figure 7As shown, the picking mechanism 4 includes a cover 42 that is movably inserted into the sorting box 3. A fixing block 46 is installed through the surface of the cover 42. A third telescopic spring 411 is fixedly installed inside the fixing block 46. The other end of the third telescopic spring 411 is fixedly installed with a sliding piece 48. The sliding piece 48 slides inside the fixing block 46. And a second clamping block 44 is fixedly installed on the side of the sliding piece 48 away from the third telescopic spring 411. A first clamping block 43 is fixedly installed on the side of the closing plate 21 close to the second clamping block 44. The sides of the first clamping block 43 and the second clamping block 44 away from each other are both designed to be arc-shaped. And the sides of the first clamping block 43 and the second clamping block 44 away from each other are movably squeezed and connected. The cover 42 can be inserted onto the sorting box 3 to close the sorting box 3, preventing the items inside the sorting box 3 from falling out. When the cover 42 is inserted into the sorting box 3, the cover 42 will drive the second clamping block 44 to move. During the movement of the second clamping block 44, it will be squeezed by the first clamping block 43, and the second clamping block 44 will slide into the fixing block 46 by squeezing the third telescopic spring 411. After the second clamping block 44 and the first clamping block 43 cancel the squeezing, the second clamping block 44 will return to its starting position through the third telescopic spring 411. Due to the arc-shaped design of the sides of the first clamping block 43 and the second clamping block 44 away from each other, when the sorting box 3 drives the cover 42 to slide into the storage cage 1, it can prevent the second clamping block 44 from getting stuck when being squeezed by the first clamping block 43. At the same time, after the sorting box 3 is completely slid into the storage cage 1, the second clamping block 44 and the first clamping block 43 can be stuck to prevent the cover 42 from sliding off the sorting box 3 and the items inside the sorting box 3 from falling out.

[0038] As Figure 5 , Figure 6 , Figure 7 As shown, a connecting rod 47 is fixedly installed on the side of the sliding piece 48 close to the second clamping block 44. The side of the connecting rod 47 close to the third telescopic spring 411, and the end of the connecting rod 47 away from the sliding piece 48 penetrates through the inner wall of the fixing block 46 and the sorting box 3. A first sliding groove for the connecting rod 47 to move is opened on one side of the fixing block 46. A second sliding groove for the fixing block 46 to penetrate and slide is opened on one side of the sorting box 3. A handle 41 is fixedly installed at the end of the connecting rod 47 penetrating through the inner wall of the sorting box 3. Pull the handle 41, the handle 41 drives the connecting rod 47 to slide inside the first sliding groove and the second sliding groove. At the same time, the connecting rod 47 drives the sliding piece 48 to move. While the sliding piece 48 squeezes the third telescopic spring 411, the second clamping block 44 slides into the fixing block 46, canceling the squeezing between the second clamping block 44 and the first clamping block 43. At this time, the sorting box 3 can be pulled out of the storage cage 1, and then the cover 42 can be slid out of the sorting box 3 to facilitate taking the items inside the sorting box 3.

[0039] As Figure 5 , Figure 6 , Figure 7As shown, a second telescopic spring 410 is fixedly installed inside the second clamping block 44. The other end of the second telescopic spring 410 is fixedly installed with a second magnetic block 49. One end of the second magnetic block 49 away from the second telescopic spring 410 penetrates through the inner wall of the second clamping block 44. A groove for inserting the second magnetic block 49 is formed on one side of the closing plate 21 close to the second clamping block 44. A first magnetic block 45 is fixedly installed inside the groove. The first magnetic block 45 is magnetically adsorbed and connected to the second magnetic block 49. When another storage cage 1 is stacked on the surface of the pressing plate 22, due to being pressed, the pressing plate 22 will drive the closing plate 21 to slide through the driving rod 29. The closing plate 21 will be inserted into the storage cage 1 and the sorting box 3 through the insertion slot 211. At the same time, the closing plate 21 drives the first clamping block 43 to move. The movement of the first clamping block 43 will increase the area of being stuck with the second clamping block 44, which can increase the stability of the sorting box 3 assembled inside the storage cage 1. At the same time, the first magnetic block 45 on the fixed seat 23 will drive the second magnetic block 49 to move through magnetic adsorption, and the second magnetic block 49 will be inserted into the groove to maintain stability.

[0040] Working principle: Pull the connecting plate 24. The connecting plate 24 drives the slider 26 to move through the rotating shaft 27. The slider 26 slides inside the limiting groove 25. Thus, the connecting plate 24 will slide out from the middle position between the closing plate 21 and the pressing plate 22. After the connecting plate 24 slides out to a certain position, rotate the connecting plate 24 through the rotating shaft 27 so that one end of the connecting plate 24 contacts the ground. Thus, the two ends of the connecting plate 24 are respectively connected to the pressing plate 22 and the ground. Through the pulley 28 on the surface of the connecting plate 24, it is convenient for another storage cage 1 to move on the connecting plate 24, so that another storage cage 1 is stacked on the surface of the pressing plate 22; when another storage cage 1 is stacked on the surface of the pressing plate 22, due to being pressed, the pressing plate 22 will drive the closing plate 21 to slide through the driving rod 29. The closing plate 21 will be inserted into the storage cage 1 and the sorting box 3 through the insertion slot 211. At the same time, the closing plate 21 drives the first clamping block 43 to move. The movement of the first clamping block 43 will increase the area of being stuck with the second clamping block 44, which can increase the stability of the sorting box 3 assembled inside the storage cage 1. At the same time, the first magnetic block 45 on the fixed seat 23 will drive the second magnetic block 49 to move through magnetic adsorption, and the second magnetic block 49 will be inserted into the groove to maintain stability; pull the handle 41. The handle 41 drives the connecting rod 47 to slide inside the first sliding groove and the second sliding groove. At the same time, the connecting rod 47 drives the sliding piece 48 to move. While the sliding piece 48 presses the third telescopic spring 411, it slides the second clamping block 44 into the fixing block 46, so that the second clamping block 44 and the first clamping block 43 cancel the extrusion. At this time, the sorting box 3 can be pulled out from the inside of the storage cage 1, and then the cover 42 can be slid out from the sorting box 3, which is convenient for taking the items inside the sorting box 3.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
