[0026] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 7 As shown, a safe door hinge device includes: a door frame 1, a hinge assembly and a connecting shaft 16,

[0028] A servo motor 3 is fixedly connected to the top of the door frame 1, and the door frame 1 is connected with the safe door 2. A rotating shaft 5 is fixedly connected to the bottom of the servo motor 3. The door frame 1 can be used to provide support. The safe door 2 rotates on the door frame 1, thereby realizing the operation of opening or closing on the door frame 1. The servo motor 3 is used to provide a driving force for opening or closing the safe door 2. The servo motor 3 can be remotely started in the prior art. The staff only needs to remotely start the servo motor 3 to operate.

[0029] There are multiple sets of hinge assemblies, both ends of which are fixedly connected to the door frame 1 and the safe door 2 respectively, and one end of the hinge assembly close to the servo motor 3 is fixedly connected to the rotating shaft 5. When the servo motor 3 runs and drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the hinge assembly to rotate, and the hinge assembly drives the safe door 2 to rotate; and

[0030] There are multiple groups of connecting shafts 16, and the upper and lower ends of the connecting shafts 16 are fixedly connected to the hinge assemblies respectively. When the rotating shaft 5 rotates, the rotating shaft 5 drives the multiple groups of hinge assemblies to rotate through the connecting shafts 16, and the multiple groups of hinge assemblies drive the safe door 2 to open or close. Compared with the prior art, the servo motor 3 drives the rotating shaft 5 and the connecting shaft 16 to drive the safe door 2 to rotate, which is more time-saving and labor-saving, and avoids the time-consuming and labor-intensive opening of the staff. The servo motor 3 controls the safe door 2 through the multiple groups of hinge assemblies. On the one hand, it ensures the stability of the servo motor 3 controlling the safe door 2 through the hinge assembly, and on the other hand, it ensures that the safe door 2 is balanced by the rotational force of the hinge assembly. On the one hand, the connecting shaft 16 realizes the effect of transmitting the rotational power of the servo motor 3, and on the other hand, it avoids the deformation of the safe door 2 during long-term use, which affects the hinge assembly.

[0031] In some specific implementation schemes, the upper and lower ends of the safe door 2 are respectively fixedly connected with a rotating seat 10, and the upper and lower ends of the door frame 1 are provided with a rotating groove 11 around the axis of the rotating seat 10, and the rotating seat 10 is rotatably connected to the rotating groove 11. In order to further ensure the stability of the rotation of the safe door 2 on the door frame 1, the rotating seat 10 is driven to rotate in the rotating groove 11 when the safe door 2 rotates. On the one hand, the door frame 1 supports the safe door 2 in a limited manner through the limiting action of the rotating seat 10 and the rotating groove 11. On the other hand, part of the weight of the safe door 2 itself is borne by the rotating seat 10, which further reduces the stress on the hinge assembly and improves the service life of the hinge assembly.

[0032] In some specific implementation schemes, the hinge assembly includes: a limit column 7, a connecting plate 8 and a fixed plate 9, the fixed plate 9 is fixedly connected to the door frame 1, the fixed plate 9 is cooperatively connected to the connecting plate 8, the connecting plate 8 is fixedly connected to the safe door 2, the limit column 7 is provided with two groups, the two groups of limit columns 7 are respectively abutted and connected with the upper and lower ends of the fixed plate 9, the limit column 7 is fixedly connected to the connecting shaft 16, and the limit column 7 close to the servo motor 3 is fixedly connected to the rotating shaft 5, the side end of the connecting plate 8 close to the fixed plate 9 is fixedly connected with a rotating column 12, the side end of the fixed plate 9 close to the connecting plate 8 is longitudinally provided with a clamping groove 14, the rotating column 12 is clamped in the clamping groove 14 and rotatably connected in the clamping groove 14, the upper and lower ends of the rotating column 12 are respectively fixedly connected to the limit column 7, the inner diameter of the clamping groove 14 is smaller than the diameter of the limit column 7, for the sake of those skilled in the art To help staff better understand the working principle of the hinge assembly of the utility model, when the servo motor 3 drives the hinge assembly to rotate, the rotating shaft 5 drives the rotating column 12 to rotate through the limiting column 7, and the rotating column 12 drives the safe door 2 to rotate through the connecting plate 8. At the same time, the rotating column 12 transmits the rotational force to the next group of hinge assemblies through the limiting column 7 at the bottom through the connecting shaft 16. The operating principle of the next group of hinge assemblies is the same as above, wherein the rotating column 12 is clamped in the clamping groove 14. When the rotating column 12 rotates, the fixing plate 9 limits the rotating column 12 through the clamping groove 14, thereby ensuring the stability of the safe door 2 driven by the rotating column 12 to rotate. The limiting columns 7 at the upper and lower ends of the rotating column 12, on the one hand, limit the rotating column 12 in the height direction, and on the other hand, the limiting columns 7 have the function of transmitting force.

[0033] In some specific embodiments, the fixed plate 9 is provided with an oil hole 13 longitudinally at the side end away from the rotating column 12, and a plurality of oil distribution holes 15 are provided inside the fixed plate 9 in a direction perpendicular to the axis of the rotating column 12. The upper and lower ends of the fixed plate 9 are respectively fixedly connected with oil pipes 6, and the oil holes 13 are respectively interconnected with the oil pipes 6 and the oil distribution holes 15, and the oil distribution holes 15 are cooperatively connected with the rotating column 12. When the hinge assembly is used for a long time, the lubricating oil between the hinge assemblies will be lacking, and it is troublesome to oil the hinge assembly. In order to avoid the large friction during the operation of the hinge assembly and reduce the life of the hinge assembly, the lubricating oil enters the oil hole 13 formed in the fixed plate 9 through the oil pipe 6, and the lubricating oil enters the hinge assembly from the oil hole 13 through the oil distribution holes 15, and the lubricating oil provides lubrication for the rotating column 12, wherein the limit column 7 blocks the lubricating oil in the clamping groove 14 to prevent the lubricating oil from leaking from the clamping groove 14.

[0034] In some specific implementation schemes, an oil supply device 4 is fixedly connected to the top of the door frame 1, and an oil pipe 6 is provided between the oil supply device 4 and the hinge assembly. The upper and lower ends of the oil pipe 6 are respectively fixedly connected to the oil supply device 4 and the hinge assembly, and multiple groups of oil pipes 6 are provided. The multiple groups of oil pipes 6 are respectively located between the hinge assemblies. In order to ensure that each group of hinge assemblies can be replenished with lubricating oil, the oil supply device 4 transports the lubricating oil through the oil pipe 6, and the oil pipe 6 transports the lubricating oil to each group of hinge assemblies.

[0035] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
