Abstract
Description
Technical Field
[0001] The present invention relates to a piece of furniture, and particularly to a mechanism box. Background Art
[0003] Since there were no such safes in the past as there are now, and there were few various locks like modern ones, craftsmen in the past would design some hidden compartments on furniture and make some mechanism boxes to hide valuable items. Generally, the designs were relatively concealed and opening them required techniques. However, many hidden compartments and various mechanism devices in traditional furniture have now been lost. Therefore, the inventor redesigned various hidden compartments and mechanism devices and now provides a mechanism box to fill the above-mentioned defects.
[0004] In view of the above-mentioned defects, the creator of the present invention finally obtained the present invention through long-term research and practice. Summary of the Invention
[0005] The purpose of the present invention is to provide a mechanism box to overcome the above-mentioned technical defects.
[0006] To achieve the above purpose, the technical solution adopted by the present invention is to provide a mechanism box, including the top plate, bottom plate, two side plates, a high-end plate and a low-end plate of the box. The opposite surfaces of the two side plates and the inner side of the high-end plate are all provided with the top plate sliding grooves. A mechanism device is arranged between the low-end plate and the top plate. The mechanism device includes: two rotating shafts, a moving bar, and a lock core. A lock core hole is arranged on the low-end plate. Rotating shaft mounting holes are arranged on both sides of the lock core hole. A moving bar mounting hole is arranged at the lower end of the lock core hole. A lock hole matching the lock core is arranged at one end of the top plate; Arc-shaped notches are arranged on both sides of the lock core. Eccentric circular bosses are arranged at the positions of the rotating shafts opposite to the notches. The diameter of the eccentric circular bosses matches the diameter of the arc-shaped notches. A protruding rotating button is arranged at the outer end of the rotating shaft. A gasket is arranged at the inner end of the rotating shaft. The gasket is fixed to the rotating shaft by screws; The moving bar is provided with a slope for pushing the lock core to move up and down. A step is arranged at the highest point of the slope for limiting the moving bar; A notch is arranged on the moving bar. A drop mortise is arranged on the low-end plate. When the moving bar moves to lock the lock core and the top plate, the drop mortise can fall into the notch. The depth of the notch is half of the length of the drop mortise; The low-end board has two layers, namely the inner layer and the outer layer. The lock core, the moving bar, the drop tenon and the eccentric circular boss are all arranged between the inner layer and the outer layer.
[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: The mechanism box designed by the present invention does not require a password or a key, and can be easily opened by the marks made by oneself. It is quite difficult to open the mechanism box without knowing the internal structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION
[0009] The present invention will be described in more detail in combination with the accompanying drawings with respect to its technical features and advantages.
[0010] Embodiment: A mechanism box includes a top board 3, a bottom board 15, two side boards 1, a high-end board 2 and a low-end board of the box. Slide grooves for the top board 3 are provided on the opposite surfaces of the two side boards 1 and the inner side of the high-end board 2. A mechanism device is arranged between the low-end board and the top board 3. The mechanism device includes: two rotating shafts 7, a moving bar 5, and a lock core 4. A lock core hole is provided on the low-end board. Rotating shaft 7 mounting holes are provided on both sides of the lock core hole. A moving bar 5 mounting hole is provided at the lower end of the lock core hole. A lock hole matching the lock core 4 is provided at one end of the top board 3. Arc-shaped notches are provided on both sides of the lock core 4. An eccentric circular boss 8 is provided at the position of the rotating shaft 7 opposite to the notch. The diameter of the eccentric circular boss 8 matches the diameter of the arc-shaped notch. A protruding rotating button is provided at the outer end of the rotating shaft 7. A gasket 12 is provided at the inner end of the rotating shaft 7. The gasket 12 is fixed to the rotating shaft 7 by a screw 13. The moving bar 5 is provided with a slope for pushing the lock core 4 to move up and down. A step is provided at the highest point of the slope for limiting the moving bar 5. The moving bar 5 is provided with a notch 9, and a dropping tenon 6 is provided on the low-end plate. When the moving bar 5 moves to the position where the lock core 4 is locked with the top plate 3, the dropping tenon 6 can fall into the notch 9. The depth of the notch 9 is half of the length of the dropping tenon 6. The low-end plate has two layers, namely the inner layer 11 and the outer layer 10. The lock core 4, the moving bar 5, the dropping tenon 6 and the eccentric circular boss 8 are all arranged between the inner layer 11 and the outer layer 10. A mark can be made on the rotating button protruding from the rotating shaft 7 first. When opening the box, first turn the box upside down so that the dropping tenon 6 falls back into the dropping tenon 6 hole, push the moving bar 5 to the limit position, then turn the box upside down again, and twist the two rotating buttons to turn the eccentric circular bosses 8 to the opposite side of the arc-shaped notch. The lock core 4 will automatically drop, and the top plate 3 can be opened along the sliding groove. When closing the box, close the top plate 3 along the sliding groove, push the moving bar 5 to the limit position, and the lock core 4 rises under the push of the slope of the moving bar 5 and enters into the lock hole of the top plate 3. The dropping tenon 6 falls into the notch 9 to lock the moving bar 5, making the moving bar 5 unable to move back and forth. Then twist the two rotating buttons to align the two eccentric circular bosses 8 with the arc-shaped notch, and the box is closed. In this way, with double insurance, it is very difficult for people who do not know the internal structure to open it.
[0011] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
