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 utility model.

[0026] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0028] The embodiment of the utility model provides a mounting structure for a lower hinge shaft, such as Figure 1-3As shown, the door frame column 110 and the lower hinge member 200 are provided with a lower mounting groove 111 at the bottom of the door frame column 110, and the lower mounting groove 111 can form an opening at the bottom surface of the door frame column 110. The lower hinge member 200 includes a hinge panel 210 and a hinge bottom plate 220. The hinge panel 210 is inserted in the lower mounting groove 111 to hide the hinge panel 210 in the door frame column 110. One end of the hinge bottom plate 220 is connected to the hinge panel 210, and the other end extends out of the door frame column 110. The hinge bottom plate 220 is provided with a lower hinge shaft 230, and the lower hinge shaft 230 is used to be rotatably connected with the door body. A positioning structure is provided on the lower hinge component 200, and an alignment structure matched with the positioning structure is provided on the inner wall of the lower mounting groove 111. After the hinge panel 210 is inserted into the lower mounting groove 111, the positioning structure and the alignment structure are docked with each other to position the lower hinge component 200 relative to the door frame column 110, so that the lower hinge component 200 is in the correct installation position in the lower mounting groove 111, and there is no need to adjust the position of the lower hinge component 200, so as to facilitate the subsequent installation of the lower hinge component 200 by screwing or other methods.

[0029] In some embodiments, the positioning structure includes a hinge positioning plate 240 connected to the hinge panel 210, the hinge positioning plate 240 extends in the vertical direction, the alignment structure includes an alignment groove 112, the alignment groove 112 extends in the vertical direction, the lower end of the alignment groove 112 extends to the bottom opening of the lower mounting groove 111, the alignment groove 112 also forms an opening on the bottom surface of the door frame column 110, the hinge positioning plate 240 is inserted into the alignment groove 112, and the alignment groove 112 and the hinge positioning plate 240 are used to limit the horizontal movement of the hinge panel 210 relative to the door frame column 110, so that it maintains the correct installation position.

[0030] Since the alignment groove 112 also forms an opening on the bottom surface of the door frame column 110, when the hinge panel 210 is inserted from the bottom into the lower installation groove 111, the hinge positioning plate 240 can be inserted into the alignment groove 112 without affecting the movement of the hinge panel 210 in the vertical direction, and it is also convenient for the hinge positioning plate 240 to be quickly inserted into the alignment groove 112.

[0031] A plurality of hinge positioning plates 240 may be provided, and a plurality of alignment grooves 112 may be provided accordingly to improve the positioning effect.

[0032] Furthermore, the alignment groove 112 is located on one side of the hinge positioning plate 240 in the width direction, the side of the hinge positioning plate 240 close to the alignment groove 112 is inserted into the alignment groove 112 and abuts against the bottom wall of the alignment groove 112, and the other side of the hinge positioning plate 240 away from the alignment groove 112 abuts against the inner wall of the lower mounting groove 111.

[0033] In the direction parallel to the horizontal direction and perpendicular to the width direction of the positioning plate 240, the hinge positioning plate 240 is blocked by the side wall of the alignment groove 112, making it difficult for the hinge panel 210 to move in the direction parallel to the horizontal direction and perpendicular to the width direction of the positioning plate 240. At the same time, since both sides of the hinge positioning plate 240 in the width direction are blocked by the bottom wall of the alignment groove 112 and the inner wall of the lower installation groove 111 respectively, it is difficult for the hinge panel 210 to move in the width direction of the positioning plate 240, so that the entire lower hinge component 200 is positioned in the correct installation position in the horizontal direction.

[0034] In other embodiments, the positioning structure includes a hinge positioning block 250 disposed on the top of the hinge bottom plate 220, and the alignment structure also includes an alignment through groove 113 penetrating the surface of the door frame column 110, and the hinge bottom plate 220 passes through the alignment through groove 113, so that the hinge bottom plate 220 can extend out of the door frame column 110. The hinge positioning block 250 abuts against the top wall of the alignment through groove 113, so that the hinge positioning block 250 cannot move upward in the vertical direction, thereby positioning the lower hinge component 200 in the vertical direction to ensure that the lower hinge component 200 can be in the correct installation position.

[0035] In some embodiments, a thickened layer 260 is provided on the surface of the hinge panel 210, and the hinge base plate 220 is connected to the thickened layer 260. The thickened layer 260 increases the thickness of the hinge panel 210, making the structural strength of the thickened layer 260 greater. The connection between the hinge base plate 220 and the thickened layer 260 is not easy to break, thereby ensuring a stable connection between the two and extending the service life.

[0036] The thickened layer 260 may also abut against the inner wall of the lower mounting groove 111 to further enhance the positioning effect of the lower hinge member 200 .

[0037] In some embodiments, the hinge panel 210 is also provided with a panel mounting hole 211 running through it. After the hinge panel 210 is inserted into the lower mounting groove 111, screws can be fixed on the door frame column 110, and the screws are passed through the panel mounting hole 211, so that the lower hinge component 200 is installed and fixed on the door frame column 110.

[0038] In some embodiments, a pressure bearing 270 is sleeved on the lower hinge shaft 230. After the lower hinge shaft 230 is inserted into the rotation hole of the door body, the door body will fall on the pressure bearing 270. The pressure bearing 270 can provide support for the door body to prevent the door body from being directly pressed on the hinge bottom plate 220 to avoid damaging the hinge bottom plate 220. At the same time, the pressure bearing 270 can increase the smoothness of the door body rotation, and the user can save more effort when rotating the door body.

[0039] Furthermore, a bottom plate groove 221 is provided on the hinge bottom plate 220, and the pressure bearing 270 is located in the bottom plate groove 221, thereby reducing the height of the pressure bearing 270, and a part of the door body can also fall on the hinge bottom plate 220, so that the door body is jointly supported by the hinge bottom plate 220 and the pressure bearing 270.

[0040] In the above embodiment, the hinge panel 210, the hinge bottom plate 220, the hinge positioning plate 240, the hinge positioning block 250 and the thickening layer 260 can be connected as one piece, so as to facilitate the overall manufacturing and molding, and to enhance the connection strength between each other. The lower hinge shaft 230 can be connected as one piece with the hinge bottom plate 220, or can be fixed on the hinge bottom plate 220.

[0041] The embodiment of the utility model also provides a revolving door, such as Figure 4 and Figure 5 As shown, the door body 10 and the installation structure of the lower hinge shaft as in any of the above embodiments are included. The specific description of the installation structure of the lower hinge shaft can refer to the above embodiments and will not be repeated here. A lower rotating hole is provided at the bottom of the door body 10, and the lower hinge shaft is inserted into the lower rotating hole and can rotate in the lower rotating hole, thereby realizing that the door body 10 can rotate relative to the door frame column 110.

[0042] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
