[0034] The present application provides the following description with reference to the accompanying drawings to help comprehensively understand various embodiments of the present application as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present application.

[0035] In the description of the utility model, the orientation description, such as the orientation or positional relation of the indication of up, down, front, back, left, right etc. for the orientation or positional relation shown in the drawing, is only for the convenience of describing the utility model and simplifying the description, and is not for indicating or implying that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore can not be understood as limiting the utility model.

[0036] It should be understood that when an element (e.g., a first element) is "connected" with another element (e.g., a second element), the element can be directly connected with the other element, or there can be intervening elements (e.g., a third element) between the element and the other element.

[0037] The embodiment of the utility model provides a hinge structure with detachable rotating shaft, as shown in Figures 1-4 The first hinge assembly 100 includes a first rotating seat 110, and the second hinge assembly 200 includes a second rotating seat 210, and the first rotating seat 110 and the second rotating seat 210 are both provided with a through hole 101 that is butted with each other, and the rotating shaft 300 is arranged in the through hole 101 of the first rotating seat 110 and the second rotating seat 210, so that the second hinge assembly 200 can rotate relative to the first hinge assembly 100, and the first hinge assembly 100 and the second hinge assembly 200 are rotationally connected.

[0038] The side surface of the first rotating seat 110 is provided with a mounting hole 111 that is communicated with the through hole 101, and the side surface of the rotating shaft 300 is provided with a limiting groove 310, and the limiting piece 410 is detachably fixed in the mounting hole 111 and inserted into the limiting groove 310.

[0039] When the rotating shaft 300 is installed, the rotating shaft 300 is inserted into the through hole 101 of the first rotating seat 110 and the second rotating seat 210, and then the limiting piece 410 is fixed in the mounting hole 111, so that the limiting piece 410 is inserted into the limiting groove 310 of the side surface of the rotating shaft 300, and the rotating shaft 300 is limited by the limiting piece 410 to be separated from the through hole 101, so as to complete the installation of the rotating shaft 300.

[0040] In some embodiments, the limiting piece 410 is a limiting screw, the mounting hole 111 is a first threaded hole matched with the limiting screw, and the limiting piece 410 is detachably mounted by threaded connection. Meanwhile, the user can make the limiting screw move along the axial direction of the first threaded hole by screwing the limiting screw, and then insert or remove the limiting screw from the limiting groove 310 on the side of the rotating shaft 300.

[0041] Of course, it is predictable that the limiting piece 410 can also be detachably fixed in the mounting hole 111 by means of snap connection, interference fit, etc.

[0042] Further, the side wall opposite to the limiting screw of the limiting groove 310 is a plane wall, and the end of the limiting screw close to the rotating shaft 300 has a limiting wall. During the process of screwing the limiting screw into the first threaded hole, the limiting wall of the limiting screw can abut against and be flush with the plane wall, so that the rotating shaft 300 will be limited by the limiting screw and cannot rotate relative to the first hinge assembly 100, and the second hinge assembly 200 can smoothly rotate relative to the rotating shaft 300. Meanwhile, when the rotating shaft 300 inserted into the through hole 101 is not completely and accurately aligned with the limiting screw, the limiting screw can gradually push the rotating shaft 300 to rotate until the plane wall is flush with the limiting wall as the limiting wall of the limiting screw abuts against the plane wall, which also reduces the difficulty of installation.

[0043] In some embodiments, the first rotating seat 110 is provided with two, and the two first rotating seats 110 are respectively located above and below the second rotating seat 210. The side surface of each of the two first rotating seats 110 is provided with a mounting hole 111 in communication with the through hole 101. The limiting piece 410 is provided with two, and the two limiting pieces 410 are respectively detachably fixed in the mounting holes 111 of the two first rotating seats 110 and used for limiting the rotating shaft 300 from being separated from the through hole 101.

[0044] On the one hand, the number of the first rotating seat 110 is increased, which can improve the stability of the rotating connection between the first hinge assembly 100 and the second hinge assembly 200. On the other hand, the two first rotating seats 110 can respectively limit the second rotating seat 210 to move along the axial direction of the rotating shaft 300 from above and below, so that the rotating shaft 300 cannot be separated from the through hole 101 of the second rotating seat 210, and the second rotating seat 210 can rotate relative to the rotating shaft 300.

[0045] In some embodiments, as shown in Figure 2 , Figure 4 and Figure 5 , the side surface of the second rotating seat 220 is provided with a fixing hole 211 in communication with the through hole 101, and the fixing hole 211 is provided with an adjusting piece 420. The adjusting piece 420 is used for limiting the angle range through which the second hinge assembly 200 can rotate relative to the first hinge assembly 100.

[0046] by Figure 6 and Figure 7 For example, when the adjusting member 420 does not limit the range of angles that the second hinge assembly 200 can rotate relative to the first hinge assembly 100, the rotating door 10 fixed by the first hinge assembly 100 will collide with objects such as pillars, door frames, and walls. After the adjusting member 420 limits the range of angles that the second hinge assembly 200 can rotate relative to the first hinge assembly 100, such as... Figure 8 and Figure 9 As shown, the second hinge assembly 200 can rotate within a smaller range of angles relative to the first hinge assembly 100, which can prevent the revolving door 10 from hitting the collision body and thus protect the revolving door 10.

[0047] Furthermore, such as Figures 4-9 As shown, the adjusting component 420 is an adjusting screw, and the fixing hole is a second threaded hole adapted to the adjusting screw; the rotating shaft 300 includes an adjusting part 320, which has an arc-shaped surface 321 and two adjusting inclined surfaces 322, and the two adjusting inclined surfaces 322 are respectively connected to the two sides of the arc-shaped surface 321; the adjusting screw has an adjusting plane 421 at one end near the rotating shaft 300.

[0048] like Figure 5 As shown, when the adjusting plane abuts against the arc surface 321, the adjusting plane can slide on the arc surface 321. The adjusting plane does not affect the rotation of the second rotating seat 210 relative to the rotating shaft 300, and the second hinge assembly 200 can rotate relative to the first hinge assembly 100.

[0049] like Figure 9 As shown, when the adjusting plane 421 and the adjusting inclined plane 322 are in contact and aligned, further rotation will encounter greater resistance. The adjusting screw can limit the rotation of the second hinge assembly 200 relative to the first hinge assembly 100, thereby limiting the range of angles in which the second hinge assembly 200 can rotate relative to the first hinge assembly 100.

[0050] Furthermore, such as Figure 4 and Figure 5 As shown, the included angle formed by the two adjusting ramps 322 is greater than zero degrees, which correspondingly reduces the range of angles at which the second hinge assembly 200 can rotate relative to the first hinge assembly 100. When in Figure 5 In the state shown, the second hinge assembly 200 and the first hinge assembly 100 are in a closed state, extended relative to each other. When the user opens the door, the second hinge assembly 200 and the first hinge assembly 100 rotate towards each other, and the included angle between them decreases. Generally, starting from the closed state, the second hinge assembly 200 can rotate 90° relative to the first hinge assembly 100, thus forming... Figure 6In the shown state, the second hinge assembly 200 and the first hinge assembly 100 are arranged vertically; after the adjusting screw defines the angle range in which the second hinge assembly 200 can rotate relative to the first hinge assembly 100, the second hinge assembly 200 is arranged as shown in the figure. Figure 8 In the shown state, the second hinge assembly 200 can rotate relative to the first hinge assembly 100 by an angle less than 90° from the closed state, so that the rotating door 10 can be prevented from colliding with the impact body.

[0051] In some embodiments, as shown in Figure 1 and Figure 10 The first hinge assembly 100 further includes a first hinge plate 120 and a second hinge plate 130 connected to each other, and the first rotating seat 110 is connected to the first hinge plate 120. The first hinge plate 120 and the second hinge plate 130 can clamp and fix the base body such as a door frame, a fixed glass, etc. The first hinge plate 120 and the second hinge plate 130 can be fastened together by screws.

[0052] The inner side of the first hinge plate 120 can be provided with a first gusset plate 140, and the inner side of the second hinge plate 130 can be provided with a second gusset plate 150. The first gusset plate 140 is arranged between the first hinge plate 120 and the base body, and the second gusset plate 150 is arranged between the second hinge plate 130 and the base body. This can play a buffering protection role on the base body, and can prevent the first hinge plate 120 and the second hinge plate 130 from damaging the base body.

[0053] Further, the second hinge assembly 200 further includes a third hinge plate 220 and a fourth hinge plate 230 connected to each other, and the second rotating seat 210 is connected to the third hinge plate 220. The third hinge plate 220 and the fourth hinge plate 230 can clamp and fix the rotating door. The third hinge plate 220 and the fourth hinge plate 230 can be fastened together by screws.

[0054] The inner side of the third hinge plate 220 can be provided with a third gusset plate 240, and the inner side of the fourth hinge plate 230 can be provided with a fourth gusset plate 250. The third gusset plate 240 is arranged between the third hinge plate 220 and the rotating door, and the fourth gusset plate 250 is arranged between the fourth hinge plate 230 and the rotating door. This can play a buffering protection role on the rotating door, and can prevent the third hinge plate 220 and the fourth hinge plate 230 from damaging the rotating door.

[0055] Further, the first hinge plate 120 and the third hinge plate 220 are detachably fixed with a decorative cover 20. Since the decorative cover can be detached, the appearance of the hinge structure can be changed by replacing decorative covers 20 with different appearance styles. The decorative cover 20 is simple in structure, which not only saves cost, but also effectively makes the product adapt to the trend of different time periods.

[0056] The decorative cover 20 is detachably fixed on the first hinge plate 120 and the third hinge plate 220 by a clamping and fixing mode.
