Description

Technical Field

[0001] The present invention relates to the field of dark boxes of safes (cabinets), and in particular to a dark box device. Background Art

[0002] The main purpose of a safe is to prevent thieves, robbers or outsiders from opening and obtaining property or important documents inside. Users often place important documents and valuables in a safe. When an outsider uses violence to forcefully open the safe, the important documents and valuables in the safe will be looted. There are usually dark boxes at the bottom of safes on the market. When an outsider opens the door of the safe, if he does not search carefully, it is easy to overlook the things hidden in the dark box, thereby deceiving thieves, robbers and outsiders through appearance to prevent property from being stolen. However, the cover of the dark box on the market is easy to open and is usually easily discovered by outsiders, or the cover opening mechanism uses a switch, and the switch is arranged inside the safe, which is also easy to be found and discovered, reducing the hidden effect. These are areas that need improvement.

[0003] Another Chinese patent with patent number 202120094431.4 discloses a safe with a hidden compartment, including a box, a base fixedly connected to the lower end of the box, a slide bar is provided at both sides of the base and at the bottom, a fixing ear is fixedly connected to the front and rear ends of the base, a second shell is provided at the upper end of the box, a lamp holder is provided at the lower end face of the second shell, a protective door is provided at the front end face of the box, a partition is provided inside the box, a second baffle is fixedly connected to the upper end face of the partition, a third baffle is provided on the right side of the second baffle, a dark box is provided below the partition, a cover is provided at the upper end of the dark box, an adsorption plate is fixedly connected to both sides of the cover and at the bottom, an electromagnet is provided at the lower end of the adsorption plate, and a dark box is fixedly connected to the lower end of the electromagnet. It improves the safety by providing a dark box in the box, and is worthy of vigorous promotion. Its disadvantages are that the electromagnet is energized for a long time to adsorb the cover, resulting in large energy loss and not energy-saving; moreover, it is necessary to draw current from the circuit above, so wires need to be arranged, resulting in a complex structure and difficulty in stealth; the cover needs to be opened or closed by hand, which is not convenient and natural enough.

[0004] Therefore, there is a need in the market for a safe cabinet with a hidden box structure, which has a simple structure, is firm and reliable, is not easily discovered by outsiders, and is easy to operate. Summary of the invention

[0005] The primary technical problem solved by the present invention is to provide a dark box device which is easy to install, energy-saving and easy to use.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] according to Figures 1 to 5 A dark box device 15 includes: a box body 1, at least the top of the box body 1 is open, equipped with an openable movable cover plate 2; the invention focuses on: the movable cover plate 2 is arranged on the top of the dark box in a liftable manner; a lifting mechanism 3 is arranged on the side wall of the dark box, and the movable cover plate 2 is opened and closed by the lifting mechanism 3; a switch sensor 4 is arranged on the dark box and connected to the control module, and the control module outputs a switch instruction to the lifting mechanism 3. The switch sensor 4 preferably adopts a touch sensing element. Only when the user enters a pre-set password sequence or / and frequency, the control module will send an instruction to the lifting mechanism 3 to prevent the dark box device 15 from being opened by an outsider accidentally or intentionally. And the touch sensing element can use a sensor light or metal plate or decorative icon in the shape of a brand LOGO, which is not only beautiful but also can prevent outsiders from noticing the opening mechanism of the dark box device 15.

[0024] At least one movable cover plate 2 is used, and its size and shape match the top opening of the box body 1. The movable cover plate 2 and the box body 1 are preferably rectangular to facilitate manufacturing. The rear part of the movable cover plate 2 and the edge of the top opening of the box body 1 are connected by rotation. In this embodiment, two front and rear movable cover plates 2 are used, and the front and rear movable cover plates 2 are also connected by rotation. The rotation connection between the two movable cover plates 2 can be connected by hinges or shaft pins and sleeves. The hinges 19 or shaft pins and sleeves are usually arranged on the bottom surface of the movable cover plate 2 to increase concealment. The auxiliary lifting mechanism 3 relies on the hinge 19 connection or the shaft pin and sleeve connection to fold open and close the movable cover plate 2.

[0025] The lifting mechanism 3 includes: an output motor 5, fixed on the side of the box body 1, and connected to the output of the control module to provide power for the lifting mechanism; a gearbox 6, the input end of which is connected to the output motor 5 for speed control; a driving gear 7, fixed on the output end of the gearbox 6; a driven gear 8, which has arc-shaped teeth and is rotatably arranged on the side of the box body 1 through a connecting shaft and meshes with the driving gear 7; at least one connecting rod 9, the two ends of which are respectively axially connected to the movable cover plate 2 and the driven gear 8. In this embodiment, the connecting rod 9 is preferably two different lengths, which are correspondingly connected with the front and rear movable cover plates 2.

[0026] The driven gear 8 is in a partial sector shape, and the outer end of the sector is provided with a tooth surface meshing with the driving gear 7. The side of the dark box is arranged with a matching open position switch 10a and a closed position switch 10b on the rear lower side of the driven gear 8. When the bottom of the driven gear 8 contacts the open position switch 10a and the closed position switch 10b respectively, the output motor 5 stops working to realize the limit function. In order to improve the stable guidance, there is a guide limit structure between the driven gear 8 and the side of the dark box. The guide limit structure is a hollow C-shaped guide slide hole 11 provided on the driven gear 8, and correspondingly, a plurality of screws 12 are sleeved on the slide sleeve, passing through the guide slide hole 11 of the driven gear 8, and fixed on the side of the dark box, so that the driven gear 8 can rotate along the guide slide hole 11 when rotating. When the driven gear 8 rotates to the maximum stroke, the guide slide hole 11 will be blocked by the screw 12, thereby realizing the limit function and preventing the driven gear 8 from excessive rotation.

[0027] Finally, in order to facilitate the installation of the dark box device 15, the above-mentioned components can be installed on the inside and outside of the mounting side plate 20, such as the output motor 5 and the gearbox 6 are arranged inside the mounting side plate 20, and the driving gear 7, the driven gear 8, the connecting rod 9 and the position switch are arranged outside the mounting side plate 20, and then the mounting side plate 20 is fixed to the side wall surface of the box body 1 with screws.

[0028] like Figures 3-5A safe cabinet, which is provided with a cassette device 15 at the bottom of a cabinet body 13, a door frame 14 is provided in front of the cabinet body 13, the bottom height of the door frame 14 is substantially flush with the top of the cassette device 15, so as to increase the confidentiality of the cassette device 15, a switch sensor 4 with a brand LOGO is provided on the door frame 14, the switch sensor 4 can be a touch sensing element, the touch sensing element can be a sensor lamp or a metal plate in the shape of the brand LOGO, and connected to a control module, a password area 16 is provided on the surface of the cabinet body 13, and a storage area 17 is provided in the cabinet body 13, where users place ordinary property and documents that need to be protected. Only the signal generated by the touch of a specific mode can be received and recognized by the control module, and the switch instruction is output to the lifting mechanism 3 to make it work. Here, the touch of a specific mode can be a preset number of consecutive finger clicks, or a preset number of finger clicks combined with a short time, or clicks of various icons in different orders, or clicks of various icons in different orders combined with a short time, etc., to form a specific preset input mode, forming a preset password.

[0029] When the user uses the safe cabinet with the dark box device 15, the cabinet door 18 is opened through the password area 16 on the surface of the cabinet body 13, and then the switch sensor 4 is touched in the order and / or frequency of the password. The control module will issue a command to make the lifting mechanism 3 work, and the output motor 5 drives the driven gear 8 to rotate through the driving gear 7. The driven gear 8 rotates through the connecting rod 9 to gradually open or close the movable cover 2. When the bottom of the driven gear 8 contacts the position switch 10a in the open position or the position switch 10b in the closed position, the control module can detect the position switch signal and issue a command to stop the output motor 5 to complete the opening or closing of the dark box device 15 in the safe cabinet.

[0030] The safe cabinet described in this article refers to a relatively large safe or a relatively small safe.
