Description
Technical Field
[0001] This invention belongs to the field of safe cabinet technology, and relates to a variable rotation axis rocker for safes, used to open the door panels of safes placed in concealed spaces such as wardrobes. Background Technology
[0002] As people's living standards continue to improve, safes and security cabinets have become increasingly common in people's lives. In homes, safes are often placed in concealed spaces such as wardrobes or bedside tables. To enhance aesthetics and concealment, wooden boards or other decorative panels are usually installed on the outer door of the safe. These doors are typically hinged to the side panels of the wardrobe or bedside table. However, in actual use, the doors often interfere with or collide with these side panels, making them impossible to open.
[0003] Therefore, it is necessary to improve the existing structure and develop a variable rotation axis rocker mechanism so that the door panel always maintains a certain distance from the side panel during the rotation opening process, and there will be no interference or collision that prevents it from opening. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a variable rotation axis rocker mechanism for a safe with a reasonable structure and ingenious design.
[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a variable rotation axis rocker mechanism for a safe, the safe including a cabinet body and a door panel, characterized in that: the variable rotation axis rocker includes a first fixed plate vertically disposed on the inner wall of the side panel of the cabinet body and a second fixed plate vertically disposed on the back side of the door panel near the side panel; a transmission connecting shaft and a connecting shaft are vertically disposed at the outer end of the first fixed plate and the inner end of the second fixed plate near the first fixed plate, respectively; a first auxiliary connecting plate and a second auxiliary connecting plate are hinged to the upper ends of the transmission connecting shaft and the connecting shaft, respectively; the first auxiliary connecting plate and the second auxiliary connecting plate are connected by a... A pivot connection is provided, in which a first limiting connecting plate and a fourth limiting connecting plate are rotatably connected between the lower inner side of the first fixed plate and the lower end of the connecting shaft of the second fixed plate. The first limiting connecting plate and the fourth limiting connecting plate are rotatably connected together at one end. A second limiting connecting plate and a third limiting connecting plate are rotatably connected between the lower end of the transmission connecting shaft of the first fixed plate and the lower outer side of the second fixed plate. The second limiting connecting plate passes through the fourth limiting connecting plate and is hinged to the third limiting connecting plate. When the door panel is opened, under the action of the four limiting connecting plates, the rotation axis of the door panel changes continuously and always maintains a certain distance from the side panel.
[0006] As an improvement, the upper and lower sides of the first and second fixed plates are respectively folded to form right-angle flanges. The transmission connecting shaft and the connecting shaft are respectively vertically arranged between the upper and lower right-angle flanges of the first and second fixed plates. The first auxiliary connecting plate is L-shaped, and one end of the first auxiliary connecting plate is provided with a U-shaped connecting ear that is rotatably connected to the upper end of the transmission connecting shaft. One end of the second auxiliary connecting plate is rotatably connected to the upper end of the connecting shaft, and the other end is connected to the other end of the first auxiliary connecting plate through a rotating shaft.
[0007] Further improvements include the first, third, and fourth limiting connecting plates being combination plates consisting of two upper and lower plates, and the second limiting connecting plate being a single plate. One end of the first limiting connecting plate is clamped to the inside of the lower right-angle flange of the first fixed plate and is rotatably connected to the right-angle flange via a pin. One end of the fourth limiting connecting plate is rotatably clamped between the lower right-angle flange of the second fixed plate and the connecting shaft, and the other end of the fourth limiting connecting plate is rotatably connected to the first limiting connecting plate via a pin.
[0008] Furthermore, one end of the third limiting connecting plate is clamped to the outside of the right-angle flange at the lower end of the second fixed plate, and is rotatably connected to the right-angle flange by a pin. One end of the second limiting connecting plate can be sleeved on the transmission connecting shaft of the first fixed plate, and the other end of the second limiting connecting plate passes through the fourth limiting connecting plate and is rotatably connected to the other end of the third limiting connecting plate by a pin.
[0009] Furthermore, the end of the second limiting connecting plate connected to the transmission connecting shaft is bent, and the lengths of the four limiting connecting plates are: second limiting connecting plate > first limiting connecting plate > fourth limiting connecting plate > third limiting connecting plate.
[0010] Preferably, one side of the second limiting connecting plate has an inwardly concave arc-shaped surface corresponding to the connection between the first limiting connecting plate and the fourth limiting connecting plate.
[0011] Furthermore, the side panels and side boards of the cabinet body are fixed, and a door board is fixed to the front of the door panel.
[0012] Finally, the safe cabinet includes a safe or vault.
[0013] Compared with existing technologies, the advantages of this invention are as follows: A transmission connecting shaft, a connecting shaft, and four limiting connecting plates are arranged between the door panel and the side panel. When the door panel is opened, under the action of the four limiting connecting plates, the door panel rotates and moves outward simultaneously, gradually increasing the distance between it and the side panel. Throughout the opening process, the rotation axis of the door panel continuously changes under the action of the limiting connecting plates, always maintaining a certain distance between the door panel and the side panel, preventing interference, collision, or inability to open. This invention has a simple structure and ingenious design, ensuring that the safe cabinet will not interfere with or collide with the wardrobe or bedside table, and its structure is stable and reliable.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0018] like Figures 1-3As shown, a variable rotation axis rocker mechanism for a safe cabinet is disclosed. The safe cabinet includes a cabinet body and a door panel 2. The side panel 1 of the cabinet body is fixed to a side wooden board 10. A door wooden board 20 is fixed to the front of the door panel 2. A first fixing plate 3 is vertically arranged on the inner wall of the side panel 1 of the cabinet body. A second fixing plate 4 is vertically arranged on the back of the door panel 2 near the side panel. The upper and lower sides of the first fixing plate 3 and the second fixing plate 4 are respectively folded to form right-angle flanges 31, 32 and 41, 42. Between the right-angle flanges 31 and 32 at the outer end of the first fixing plate 3... A transmission connecting shaft 5 is provided, and a connecting shaft 6 is provided between the upper and lower right-angle flanges 41 and 42 on the side of the second fixed plate 4 near the first fixed plate 3. A first auxiliary connecting plate 7 and a second auxiliary connecting plate 8 are respectively hinged to the upper ends of the transmission connecting shaft 5 and the connecting shaft 6. The first auxiliary connecting plate 7 is L-shaped, and one end of the first auxiliary connecting plate 7 is provided with a U-shaped connecting ear that is rotatably connected to the upper end of the transmission connecting shaft 5. One end of the second auxiliary connecting plate 8 is rotatably connected to the upper end of the connecting shaft 6, and the other end is connected to the other end of the first auxiliary connecting plate 7 through a rotating shaft. A first limiting connecting plate 9 and a fourth limiting connecting plate 13 are rotatably connected between the lower inner side of the first fixed plate 3 and the lower end of the connecting shaft 6 of the second fixed plate 4. The first limiting connecting plate and the fourth limiting connecting plate are connected together by a rotating shaft. A second limiting connecting plate 11 and a third limiting connecting plate 12 are rotatably connected between the lower end of the transmission connecting shaft 5 of the first fixed plate 3 and the lower outer side of the second fixed plate 4. The first limiting connecting plate 9, the third limiting connecting plate 12, and the fourth limiting connecting plate 13 are all combination plates of two plates, while the second limiting connecting plate 11 is a single plate. One end of the first limiting connecting plate 9 is clamped to the right-angle flange at the lower end of the first fixed plate 3. On the inside of plate 32, it is rotatably connected to the right-angle flange 32 via a pin. One end of the fourth limiting connecting plate 13 is rotatably clamped between the lower right-angle flange 42 of the second fixed plate 4 and the connecting shaft 6. The other end of the fourth limiting connecting plate 13 is rotatably connected to the first limiting connecting plate 9 via a pin. One end of the third limiting connecting plate 12 is clamped to the outside of the lower right-angle flange 42 of the second fixed plate 4 and is rotatably connected to the right-angle flange 42 via a pin. One end of the second limiting connecting plate 11 is sleeved on the transmission connecting shaft 5 of the first fixed plate 3. The other end of the second limiting connecting plate 11 passes through the fourth limiting connecting plate 13 and is rotatably connected to the other end of the third limiting connecting plate 12 via a pin. When the door panel 2 is opened, under the action of the four limiting connecting plates, the rotation axis of the door panel 20 changes continuously and always maintains a certain distance from the side panel 10; the end of the second limiting connecting plate 11 connected to the transmission connecting shaft 5 is bent, and the lengths of the four limiting connecting plates are: second limiting connecting plate 11 > first limiting connecting plate 9 > fourth limiting connecting plate 13 > third limiting connecting plate 12; in addition, one side of the second limiting connecting plate 11 is provided with an inwardly concave arc-shaped concave surface 111 corresponding to the connection between the first limiting connecting plate 9 and the fourth limiting connecting plate 13.
[0019] The working principle is as follows: In the initial state, the transmission connecting shaft 5 is the rotation axis, and the first limiting connecting plate 9, the second limiting connecting plate 11, the third limiting connecting plate 12, and the fourth limiting connecting plate 13 are the limiting constraint points. Figure 1 When door panel 2 is opened, under the action of the first limiting connecting plate 9, the third limiting connecting plate 12, and the fourth limiting connecting plate 13, the second limiting connecting plate 11 is driven to rotate around the transmission connecting shaft 5, causing door panel 2 to rotate and open while moving outward, gradually pulling away from the side wooden board 10; when door panel 2 is opened to about 40° ( Figure 2 Under the main force of the first limiting connecting plate 9, the door panel 2 no longer moves outward, but mainly rotates to open. After rotating and opening to the correct position, the door panel 20 and the side panel 10 will maintain a certain distance. Figure 3 ).
[0020] Throughout the opening process, the rotation axis of the door panel 2 changes continuously under the action of the four limiting connecting plates, ensuring that the door panel 20 and the side panel 10 maintain a certain distance, preventing interference, collision, and the inability to open.
[0021] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
