The damping shafts 4 are fixedly inserted through the shaft hole, and the damping shafts 4 are fixedly connected to the first hinge 1 or the second hinge 7 through the fixing block. Two adjacent damping shafts 4 can rotate relative to each other.

[0027] In this embodiment, the first hinge 1 and the second hinge 7 are similar in shape, with intersecting teeth and a shaft hole in the middle for inserting a straight damping shaft 4 to concentrically limit the movement of multiple straight rotating shafts. The appearance and interface, required length and damping requirements are designed according to the appearance and installation position of the equipment. The basic torque value and combination quantity of the straight damping shaft 4, as well as the first hinge 1 and the second hinge 7 of different lengths, are selected to achieve adaptability to different devices.

[0028] Furthermore, such as Figure 2 As shown, the damping shaft 4 is a single-section damping shaft 4, comprising a first main body 42 and a second main body 41 rotatably connected, both the first main body 42 and the second main body 41 being provided with a fixing mechanism; as Figure 3 As shown, the fixing mechanisms of two adjacent damping shafts 4 are assembled to form a fixing hole. The fixing block is detachably connected to the fixing hole, facilitating combination and expansion. When the two damping shafts are installed head-to-head, they can be radially fixed with a single screw, improving integration.

[0029] Furthermore, the first body 42 is fixedly connected to the first hinge 1 by a fastener, and the second body 41 is fixedly connected to the second hinge 7 by a fastener; or the first body 42 is fixedly connected to the second hinge 7 by a fastener, and the second body 41 is fixedly connected to the first hinge 1 by a fastener.

[0030] Furthermore, both the first hinge 1 and the second hinge 7 are provided with positioning grooves, and two adjacent fixing blocks are respectively set in the positioning grooves of the first hinge 1 and the second hinge 7, so that the damping shaft 4 is pressed onto the first hinge 1 and the second hinge 7 respectively.

[0031] Furthermore, the positioning groove of the first hinge or the second hinge is provided with an arc surface, and the arc surface is provided with mounting screw holes that cooperate with the fixing member. The fixing block cooperates with the mounting screw holes to form a fixation, pressing the damping shaft 4 onto the first hinge 1 or the second hinge 7.

[0032] Furthermore, the rotatable connection end between the first body 42 and the second body 41 is disposed in the positioning groove to ensure that the rotation of the damping shaft is not obstructed.

[0033] Furthermore, the number of the fixed blocks is one more than the number of the damping shafts 4.

[0034] Furthermore, the fixing block includes a first fixing member 3 and a second fixing member 6, wherein the first fixing member 3 and the second fixing member 6 are installed in opposite directions.

[0035] Furthermore, the limiting member 5 seals the left and right ends of the series-connected damping shaft 4.

[0036] Example 2

[0037] Compared with the first embodiment described above, the difference lies in that, in this embodiment, reference is made to the appendix. Figure 1 As shown, there are five damping shafts 4 and six fixing blocks.

[0038] In this embodiment, the damping hinge is made of titanium alloy, and the straight damping shaft 4 has a diameter of 6mm, a length of 18mm, and a torque of 0.8Nm.

[0039] Furthermore, the first fixing block and the second fixing block are arranged alternately along multiple fixing holes.

[0040] Furthermore, the fixing mechanism is a semi-circular hole structure, and the fixing mechanisms of the first body 42 and the second body 41 of the two adjacent damping shafts 4 are combined to form a circular fixing hole.

[0041] Furthermore, by inserting the fixing block into the fixing hole with screw 2, the damping shaft 4 is pressed onto the hinge. When the first hinge 1 and the second hinge 7 rotate relative to each other, the damping shaft 4 will provide damping torque. Assuming that the torque of one end of the shaft is T, the damping torque of the 5-segment damping shaft is 5T.

[0042] In this embodiment, the combined torque of the five straight damping shafts can reach 4 N·m. When the equipment is in use, two sets of damping hinges on the left and right sides are used, and their torque can reach 4 N·m.
