[0030] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Example:

[0033] Refer to the attached Figure 1 A multi-layer plastic turnover box of this embodiment includes a bottom frame 1, and a handrail 13 is fixedly installed on one side of the bottom frame 1. The handrail 13 is convenient for the operator to push the turnover box to move. The outer wall of the handrail 13 is processed with anti-slip grooves, and the anti-slip grooves increase the friction between the handrail 13 and the operator's palm. Moving wheels 14 are fixedly installed at the four corners of the bottom of the bottom frame 1, so that the turnover box can be easily moved, thereby improving the flexibility of the turnover box.

[0034] Refer to the attached Figure 3 and Figure 8 A sliding groove 3 is provided on the bottom frame 1, and a placement box 4 is slidably installed in the sliding groove 3. The sliding groove 3 allows the placement box 4 to be slidably installed on the bottom frame 1, which is convenient for taking out and putting back. A handle 15 is fixedly installed on one side of the placement box 4. An adsorbent is arranged in the placement box 4. The adsorbent is selected from activated carbon to remove odor.

[0035] Refer to the attached Figure 1 and Figure 2 A limiting assembly 5 for limiting the placement box 4 is provided on the bottom frame 1. The limiting assembly 5 includes two connecting shafts 501 fixedly mounted on the bottom frame 1, and the cross section of the connecting shaft 501 is T-shaped. A No. 1 spring 502 is fixedly mounted on the connecting shaft 501, and a limiting plate 503 is rotatably mounted on the connecting shaft 501. During use, under the elastic action of the No. 1 spring 502, the limiting plate 503 contacts the outer wall surface of the placement box 4 to limit the placement box 4 and prevent the placement box 4 from sliding out of the sliding groove 3. When the adsorbent needs to be replaced, the operator rotates the limiting plate 503 to release the limit on the placement box 4, thereby pulling the placement box 4 out of the sliding groove 3.

[0036] Refer to the attached Figure 1-Figure 3, a plurality of connecting frames 2 are arranged above the bottom frame 1. In actual use, the operator selects a suitable number of connecting frames 2 and assembles them with the bottom frame 1 according to actual needs. Among them, a snap-fit ​​block 22 is fixedly installed on the top of the bottom frame 1, and a snap-fit ​​groove 23 is provided at the bottom of the connecting frame 2. The snap-fit ​​block 22 and the snap-fit ​​groove 23 are adapted to each other. By setting the snap-fit ​​block 22 and the snap-fit ​​groove 23, the quick splicing between the bottom frame 1 and the connecting frame 2 is realized.

[0037] Refer to the attached Figure 3 , Figure 4 and Figure 7 , lower connecting blocks 7 are fixedly installed at the four corners of the top of the bottom frame 1, and a No. 1 slot 9 is opened on the lower connecting block 7, and upper connecting blocks 8 are fixedly installed at the four corners of the connecting frame 2, and a No. 2 slot 10 is opened on the upper connecting block 8, and the No. 2 slot 10 is the same size as the No. 1 slot 9, and connecting members 11 are arranged at the four corners of the bottom frame 1, and the connecting member 11 includes a plug-in rod 1101, and the plug-in rod 1101 is adapted to the No. 1 slot 9 and the No. 2 slot 10, wherein the plug-in rod 1101 has a variety of lengths. In actual use, the plug-in rod 1101 of appropriate length is selected according to the number of connecting frames 2, and a lifting handle 1102 is fixedly installed on the top of the plug-in rod 1101, and a No. 1 installation slot is opened on the plug-in rod 1101, and a No. 2 spring 1103 is fixedly installed in the No. 1 installation slot, and a No. 1 limit block 1104 is fixedly installed on the outer end of the No. 2 spring 1103.

[0038] During the assembly process, the snap-fit ​​block 22 at the top of the bottom frame 1 and the snap-fit ​​groove 23 at the bottom of the connecting frame 2 are first used to realize the quick splicing between the bottom frame 1 and the connecting frame 2. At this time, the No. 1 slot 9 and the No. 2 slot 10 set on the same side are coaxially set, and then the plug-in rod 1101 is inserted into the No. 1 slot 9 and the No. 2 slot 10. During this process, the operator first presses the No. 1 limit block 1104 to shrink it into the No. 1 installation groove, and then slowly inserts the plug-in rod 1101 into the No. 2 slot 10 and the No. 1 slot 9. When the No. 1 limit block 1104 pops out from the No. 1 installation groove below the lower connecting block 7, the assembly between the bottom frame 1 and the connecting frame 2 is realized.

[0039] Refer to the attached Figure 3 and Figure 5 A No. 1 air vent 6 connected to the sliding groove 3 is provided on the bottom frame 1, and a plurality of No. 2 air vents 12 are provided at the bottom of the connecting frame 2. Through the No. 1 air vent 6 and the No. 2 air vent 12, air circulation in the turnover box is achieved to reduce odor.

[0040] Refer to the attached Figure 5 and Figure 6The inner wall of the connection frame 2 is provided with a number of connection grooves 16 at equal intervals, and a partition 17 is slidably installed in the connection groove 16. The partition 17 is provided with a plurality of ventilation grooves 18, and the ventilation grooves 18 are used to maintain air circulation. The installation position of the partition 17 depends on the actual situation. The partition 17 is provided to improve the space utilization rate in the connection frame 2, making the storage more orderly and efficient. The connection frame 2 is provided with a number of snap-in grooves 19 equal to the number of the connection grooves 16. The connection grooves 16 and the snap-in grooves 19 arranged on the same side are connected, and the connection grooves 16 and the snap-in grooves 19 are arranged vertically. The partition 17 is provided with a No. 2 installation groove, and a No. 3 spring 20 is fixedly installed in the No. 2 installation groove, and a No. 2 limit stopper 21 is fixedly installed at the outer end of the No. 3 spring 20.

[0041] When installing the partition 17, the operator first inserts the partition 17 into the connecting groove 16 at the appropriate position, and then presses the No. 2 limit block 21 to make it retract into the No. 2 installation groove. During the movement, the inner wall of the connecting groove 16 hinders the No. 2 limit block 21, preventing it from popping out. When the No. 2 limit block 21 moves to the same horizontal plane as the snap-in groove 19, the No. 2 moving block pops out from the snap-in groove 19, thereby realizing the installation of the partition 17.

[0042] The present application realizes the rapid splicing between the bottom frame 1 and the connecting frame 2 through the snap-fit ​​block 22 of the bottom frame 1 and the snap-fit ​​groove 23 of the connecting frame 2. The user can select different numbers of connecting frames 2 for assembly according to actual needs, thereby improving the modularity and scalability of the turnover box. The design of the plug-in rod 1101 and the first slot 9 and the second slot 10 further enhances the connection strength between the bottom frame 1 and the connecting frame 2, and the different lengths of the plug-in rod 1101 can be adjusted according to the number of connecting frames 2, thereby increasing the flexibility of use.

[0043] The activated carbon adsorbent arranged in the placement box 4 can effectively remove the odor in the turnover box and keep the air in the box fresh. The first air vent 6 and the second air vent 12 opened on the bottom frame 1 and the connecting frame 2 promote the air circulation in the box and further reduce the accumulation of odor. The design of the limiting plate 503 and the first spring 502 realizes the stable positioning of the placement box 4, avoids the placement box 4 from accidentally sliding out of the sliding groove 3, and improves the safety of the turnover box.

[0044] A partition 17 is provided inside the connecting frame 2, through which the internal space of the connecting frame 2 is divided into a plurality of areas, thereby improving space utilization and making storage more orderly and efficient. The partition 17 is stably installed and easy to operate through the design of the snap-in groove 19 and the No. 3 spring 20.
