[0031] Embodiment 1:
[0032] like Figures 1-2 As shown, the utility model proposes a spring lock, the spring lock 3 comprises a long strip-shaped locking member 31, a spring 32 and a long strip-shaped fixing member 33, one end of the fixing member 33 is closed and the other end is open, the locking member 31 is arranged in the open end of the fixing member 33 and slidably cooperates with it, the spring 32 is located between the inner end surface of the locking member 31 and the inner bottom surface of the closed end of the fixing member 33, a pushing portion 311 is provided on the outer side surface of the locking member 31, and a pushing hole 312 connected with the interior of the fixing member 33 is opened at the outer side surface corresponding to the pushing portion 311, so as to realize the function of quick locking and unlocking.
[0033] Embodiment 2:
[0034] like Figures 3-4 As shown, this embodiment is improved on the basis of embodiment 1. The structure and principle of this embodiment are the same as those of embodiment 1. The similarities are not repeated here. The main difference is that the spring lock 3 includes two long strip-shaped locking members 31, a spring 32 and a long strip-shaped fixing member 33. The two locking members 31 are respectively located in the two ends of the fixing member 33 and slide with it. The spring 32 is located between the inner end surfaces of the two locking members 31. The outer surfaces of the locking members 31 are provided with a pushing portion 311. The fixing member 33 has a pushing hole 312 connected to the inside thereof at the corresponding pushing portion 311 on the same outer surface. To realize the function of quick unlocking or locking, the two pushing portions are pushed to the middle of the fixing member at the same time. At this time, the spring is compressed and the pushing member is completely retracted into the fixing member, which is the unlocking state. On the contrary, the pushing portion is released, and the spring drives the locking member to reset and extend out of the fixing member under the action of elastic force, which is the locking state. The above-mentioned locking state or unlocking state will be different according to the actual use.
[0035] The specific shape of the fixing member 33 is not limited, as long as it is in the shape of an elongated strip and can accommodate the elongated locking member 31 to slide therein.

[0039] The box body 1 is foldable and comprises two outer frames 11 with access openings 11a, a bottom plate 12, two side plates 13 and a top plate 14. Specifically, the bottom surfaces of the two outer frames 11 are rotatably connected to the front and rear sides of the bottom plate 12 through a rotating shaft, and the left and right ends of the bottom plate 12 are fixed with connecting parts. The bottom surfaces of the two side plates 13 are rotatably connected to the corresponding connecting parts through a rotating shaft. The left and right ends of the two outer frames 11 are respectively connected to the inner sides of the corresponding side plates 13. The two access openings 11a are rotatably connected with the box doors 2, and the box doors 2 are installed with spring locks 3. The top plate 14 is detachably connected to the two outer frames 11. Specifically, the two outer frames 1 1, a plurality of snap fasteners 111 for fixing the top plate 14 are rotatably connected on the top, the top plate 14 is provided with snap-fitting parts 141 corresponding to the plurality of snap fasteners 111, and the two outer side surfaces of the bottom plate 12 are provided with snap-fitting grooves 121 snap-fitting with the snap fasteners 111; the function of folding and stacking the box as a whole is realized, the snap fasteners snap-fitting with the top plate on the outer frame are unlocked, the top plate is removed, and then the outer frame is unlocked from the side plates, the outer frame is rotated along its hinge point and sequentially stored in the storage cavity, and then the two side plates are rotated along their hinge points and sequentially stored in the storage cavity, the two outer frames and the two side plates are sequentially stacked and placed in parallel inside the storage cavity, and then the top plate is placed just above the side plate at the top, so that the folding function of the storage box can be realized.
[0040] The box door 2 consists of a left box door 21 and a right box door 22. The two side surfaces at the left end of the left box door 21 and the two side surfaces at the right end of the right box door 22 are coaxially rotatably connected to the side surfaces corresponding to the leftmost end and the rightmost end of the loading and unloading opening 11a, respectively. The left box door 21 and the right box door 22 are both provided with spring locks 3. The box door is a double-opening type, and the spring locks are used to realize the quick locking or unlocking function of the left and right boxes, so as to avoid the problem that the box door is easily opened due to the shaking of the box body.
[0041] The box door 2 consists of a left box door 21 and a right box door 22 hinged on the side of the left box door 21. The upper and lower inner sides of the loading and unloading port 11a are provided with sliding grooves. The two side surfaces at the right end of the right box door 22 are rotatably connected with the side surfaces corresponding to the rightmost end of the sliding groove. The two side surfaces at the left end of the left box door 21 are rotatably provided with pulleys that slide with the sliding groove. The box door 2 is provided with a spring lock 3. The box door is a folding and sliding opening and closing type. The spring lock realizes the function of quickly locking or unlocking the box door, so as to avoid the problem that the box door is easily opened due to the shaking of the box body. For doors of the same size, this opening method has a smaller rotation radius when the box door is opened.
[0042] like Figure 12-13 As shown, when there are two or more boxes 1, the boxes 1 are stacked in sequence along the vertical direction. Of the two adjacent boxes 1, the box 1 located at the bottom is engaged with the corresponding engaging grooves 121 on the bottom plate 14 of the box 1 located at the top through a plurality of snap fasteners 111 on the outer frame 11; while stacking of multiple groups of boxes is achieved, the firmness and stability thereof are significantly improved due to the cooperation of the snap fasteners and the engaging grooves, and the user can customize the number of boxes to be stacked.
