Description

Technical Field

[0001] This utility model relates to the field of sand table technology, specifically a waterproof, foldable, and portable sand table. Background Technology

[0002] A sand table is a scene model made of sand, models, and other materials according to a certain scale. By changing the shape of different models and sand, many different scenes can be simulated. It can be used not only for psychotherapy but also as a plaything for children. It is widely used in schools, kindergartens, playrooms, and other places.

[0003] In terms of materials, existing sand trays are mostly made of wood. If a wet sand tray (water is added to the sand) is needed during use, the waterproofness of the tray base needs to be considered. Traditional sand trays mostly use a fixed inner lining or a waterproof structure with painted inner surface. This is not only very inconvenient to disassemble and replace, but also not conducive to cleaning the sand tray after use, making it very inconvenient to use. Therefore, a waterproof, foldable, and portable sand tray is proposed. Utility Model Content

[0022] The support mechanism is used for the installation of the sandbox. The support mechanism includes a leg mounting base 8, a flip-up leg 9, a limiting pin 10, and a spring 11. The flip-up leg 9 is flipped and installed on the lower part of the sandbox base 1 via the leg mounting base 8. Specifically, see attached... Figure 4 As shown, four outrigger mounting seats 8 are provided. The outrigger mounting seats 8 are fixedly installed to the lower part of the sandbox base 1 by bolts. The storage slot is opened in the middle of the bottom side of the outrigger mounting seat 8. In order to realize the working limit of the flipping outrigger 9, as shown in the attached figure Figure 5 As shown, the upper end of the flip-up support leg 9 is rotatably fitted into the inner side of the storage slot. A first limiting pin 12 and a second limiting pin 13 are respectively provided on both sides of the support leg mounting base 8. The cap sides of the first limiting pin 12 and the second limiting pin 13 are threaded into the screw holes provided on the edge of the support leg mounting base 8. The insertion ends of the first limiting pin 12 and the second limiting pin 13 are respectively inserted into the shaft holes provided on both sides of the upper part of the flip-up support leg 9 for support installation. The limiting insertion pin 10 is movably installed inside the end side of the flip-up support leg 9 by being pushed by a spring 11. Specifically, the upper part of the flip-up support leg 9 is provided with a insertion pin mounting hole, and the limiting insertion pin 10 is slidably installed inside the insertion pin mounting hole by being pushed by a spring 11. On the side, an unlocking push block 16 is fixedly installed on the edge of the limiting plug 10. The limiting holes are set in pairs, with two sets of limiting holes respectively opened on both sides of the inside of the storage slot. After installation, the end of the limiting plug 10 is inserted into the limiting hole. The flip leg 9 is locked and limited by the limiting plug 10 supported by the spring 11. During operation, the limiting plug 10 and the two sets of limiting holes in the slot of the leg mounting seat 8 are alternately engaged, which can realize the limiting and locking of the leg structure in the storage and unfolding state. The structure is simple and the operation is reliable. By flipping and switching, the leg structure can be conveniently unfolded and supported and flipped and folded for storage, which greatly improves the convenience of installation and operation of the sand table and the portability of mobile storage.

[0023] To achieve control and adjustment of the outrigger height, see attached... Figure 5As shown, a telescopic outrigger 14 is slidably inserted into the middle of the inner cavity of the flip-outrigger 9. Adjustment holes are evenly spaced on the side of the flip-outrigger 9. Fastening bolts 15 are provided on the side of the telescopic outrigger 14. The bolt end of the fastening bolt 15 passes through the adjustment hole and is threaded into the screw hole provided on the side of the telescopic outrigger 14. The height of the outrigger can be controlled and adjusted by changing the installation position of the fastening bolt 15 and the adjustment hole.

[0024] Working principle or structural principle: When the sandbox is in the storage state, the sandbox lid 2 is closed and locked, and the four sets of flip-up support legs 9 are locked by the limiting pins 10 and flipped into the lower part of the sandbox base 1. The user can easily move and carry the sandbox by flipping the handle 6. When in use, use your finger to pull the unlocking push block 16 at the bottom of the flip-up support leg 9 to move the limiting pin 10 backward and disengage it from a set of limiting holes in the rotating groove of the support leg mounting base 8. Then, flip the flip-up support leg 9 to support and unfold it. After completion, the limiting pin 10 at the top of the flip-up support leg 9 is inserted and installed into another set of limiting holes in the rotating groove of the support leg mounting base 8. After unfolding, the flip-up support leg 9 is locked and limited. The remaining three sets of flip-up support legs 9 are unfolded and supported in sequence. Then, the support height of the telescopic support legs 14 is adjusted by stretching and pulling to support the sandbox. The working height is adjusted, and after adjustment, the telescopic support leg 14 is locked and limited by tightening bolt 15. Then, the limit lock 5 is unlocked and the sandbox cover 2 is opened by flipping, completing the sandbox unfolding and installation. During the operation, the waterproof groove seat 3 can prevent water from corroding the sandbox seat 1. After use, the waterproof groove seat 3 can be disassembled and removed independently for cleaning. The extended telescopic support leg 14 is reset, and then the flipped support leg 9 is unlocked by pulling the unlocking push block 16 and flipped to store it. After storage, the spring 11 pushes the limit insertion post 10 to connect with the limit insertion hole in the groove of the support leg mounting seat 8 to achieve the locking and limiting of the flipped support leg 9 after storage. The sandbox cover 2 is closed and locked, completing the folding and storage of the sandbox.

[0025] In summary, this sandbox adopts a split-type waterproof structure. A waterproof groove seat 3 is installed inside the sandbox base 1. The waterproof groove seat 3 is a split type, connected to the mounting cavity 7 in the middle of the sandbox base 1 via a groove structure on its side. The structure is simple and easy to assemble and disassemble. While achieving waterproof protection for the inner cavity of the sandbox base 1, it also allows for convenient disassembly and separation of the waterproof groove seat 3. After use, the waterproof groove seat 3 can be independently disassembled and cleaned, improving the convenience of sandbox cleaning and maintenance. It adopts a foldable, storage-type box structure, and the main body of the sandbox base 1 is a box-type portable container. The convenient flip-up support leg 9 adopts a telescopic and adjustable working structure and is connected and installed through the support leg structure of the support leg mounting base 8. The flip-up support leg 9 is locked and limited by the limiting plug 10 supported by the spring 11. During operation, the limiting plug 10 and the two sets of limiting holes in the rotating groove of the support leg mounting base 8 are alternately engaged to realize the limiting and locking of the support leg structure in the storage and unfolding state. The structure is simple and reliable. By flipping and switching, the support leg structure can be conveniently unfolded for support and flipped and folded for storage, which greatly improves the convenience of installation and operation of the sand table and the portability of mobile storage.
