A letterbox

Abstract

A mechanism box includes a top plate, a bottom plate, two side plates, a high-end plate, and a low-end plate. The opposing surfaces of the two side plates and the inner side of the high-end plate are provided with sliding grooves for the top plate. The mechanism is characterized by a rotating core, an inner sleeve, an outer sleeve, and a lock cylinder. One end of the rotating core has a protrusion. The outer sleeve fits over the protrusion at one end of the rotating core, and the inner sleeve fits over the other end of the rotating core and is fixed to the rotating core by screws or pins. One end of the top plate has a lock hole that matches the lock cylinder. This mechanism box requires no password or key and can be easily opened using self-made markings. However, if the markings are unknown, perfectly aligning the notches on the inner and outer sleeves is quite difficult, making opening the mechanism box challenging.

Description

Technical Field

[0001] This utility model relates to a piece of furniture, and more particularly to a mechanism box. Background Technology

[0002] With the nation's increasing emphasis on traditional culture, local governments, following directives from higher authorities, are actively excavating and protecting various intangible cultural heritage projects. The inventor, responding to the government's call, has been excavating and protecting the mortise and tenon techniques and hidden compartments in traditional furniture. Because safes like those we have today didn't exist in the past, and modern locks were rare, craftsmen used to design hidden compartments and mechanical boxes in furniture to conceal valuables. These designs were generally quite concealed, and opening them required skill. However, many of the hidden compartments and mechanical devices in traditional furniture have been lost. Therefore, this invention redesigns various hidden compartments and mechanical devices, and now provides a mechanical box to fill the aforementioned gaps.

[0003] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content

[0004] The purpose of this utility model is to provide a mechanism box to overcome the above-mentioned technical defects.

[0005] To achieve the above objectives, the present invention provides a mechanism box, comprising a top plate, a bottom plate, two side plates, a high-end plate, and a low-end plate. The opposing surfaces of the two side plates and the inner side of the high-end plate are provided with sliding grooves for the top plate. A mechanism is provided between the low-end plate and the top plate. The mechanism includes a rotating core, an inner sleeve, an outer sleeve, and a lock cylinder. One end of the rotating core has a protrusion. The outer sleeve is fitted over the protrusion at one end of the rotating core. The inner sleeve is fitted over the other end of the rotating core and fixed to the rotating core by screws or pins. One end of the top plate has a lock hole matching the lock cylinder.

[0006] The lower end of the lock cylinder is provided with a tenon, and the opposite surfaces of the inner sleeve and the outer sleeve are provided with a groove that is half of the tenon.

[0007] The low-end plate is provided with a lock cylinder hole, and the lock cylinder is installed in the lock cylinder hole. The lower end of the lock cylinder hole is provided with a rotating core hole, and the rotating core is installed in the rotating core hole. The inner sleeve and the outer sleeve are both provided in the rotating core hole. The outer sleeve is provided with an outer sleeve boss, which is located outside the low-end plate. The inner sleeve is provided with an inner sleeve boss, which is located inside the low-end plate.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the mechanism box designed by this utility model does not require a password or a key. It can be easily opened by markings made by oneself. If the markings are not known, it is quite difficult to align the grooves set on the inner and outer sleeves completely, so it is not easy to open the mechanism box. Attached Figure Description

[0016] The technical features and advantages of this utility model will be described in more detail with reference to the accompanying drawings.

[0017] An embodiment of a mechanism box includes a top plate 3, a bottom plate 4, two side plates 1, a high-end plate 11, and a low-end plate 2. The opposite surfaces of the two side plates 1 and the inner side of the high-end plate 11 are provided with sliding grooves for the top plate 3. A mechanism is provided between the low-end plate 2 and the top plate 3. The mechanism includes a rotating core 6, an inner sleeve 7, an outer sleeve 9, and a lock cylinder 5. One end of the rotating core 6 is provided with a boss. The outer sleeve 9 is fitted onto one end of the boss of the rotating core 6. The inner sleeve 7 is fitted onto the other end of the rotating core 6 and is fixed to the rotating core 6 by screws or pins 8. One end of the top plate 3 is provided with a lock hole that matches the lock cylinder 5.

[0018] The lower end of the lock cylinder 5 is provided with a tenon, and the opposite surfaces of the inner sleeve 7 and the outer sleeve 9 are provided with a groove 10 for half a tenon;

[0019] The lower plate 2 has a lock cylinder hole, and the lock cylinder 5 is installed inside the lock cylinder hole. A rotating core hole is located at the lower end of the lock cylinder hole, and the rotating core 6 is installed inside the rotating core hole. The inner sleeve 7 and the outer sleeve 9 are both located inside the rotating core hole. The outer sleeve 9 has an outer sleeve 9 boss, which is located outside the lower plate 2. The inner sleeve 7 has an inner sleeve 7 boss, which is located inside the lower plate 2. First, make a mark that only you can understand on the bosses of the rotating core 6 and the outer sleeve 9. Using this mark, you can easily align the grooves 10 on the inner and outer sleeves. This is how the lock cylinder... The tenon on lock cylinder 5 can fall into the groove 10. At the same time, lock cylinder 5 comes down from the lock hole of top plate 3. Top plate 3 is pulled out through the sliding groove, and the box is opened. To close the box, push top plate 3 in through the sliding groove, and then turn the box upside down. Lock cylinder 5 falls into the lock hole of top plate 3. Rotate the boss of rotating core 6 and the boss of outer sleeve 9 to make the tenon on lock cylinder 5 misalign with groove 10. Lock cylinder 5 will not come down, and the box will be locked. If you do not know the markings, it is quite difficult to align groove 10 on inner sleeve and outer sleeve with the tenon on lock cylinder 5. Therefore, it is not easy to open the mechanism box.

[0020] The above description is merely a preferred embodiment of this utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of this utility model, all of which will fall within the protection scope of this utility model.
