[0033] A door shaft base according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0034] Reference Figure 1 A door axis base according to an embodiment of the utility model includes a first mounting plate 100 and a second mounting plate 120 .

[0035] Reference Figure 1 and Figure 4 For the first mounting plate 100, the first mounting plate 100 is horizontally arranged and is in the shape of a long strip. A bearing assembly 110 is arranged at one end of the first mounting plate 100. The bearing assembly 110 is used to support the swinging of the door leaf, so that the door axis base can support the swinging opening and closing of the door leaf.

[0036] Reference Figure 1 and Figure 5 For the second mounting plate 120, the second mounting plate 120 includes a transverse plate portion 130 and a vertical plate portion 140 which are perpendicular to each other. The transverse plate portion 130 is in the shape of a long strip, and the bottom of the vertical plate portion 140 is connected to one side of the length direction of the transverse plate portion 130. The vertical plate portion 140 is used to be installed on the left door frame or the right door frame, so that the door axis base can be fixed on the door frame.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Specifically, the first mounting plate 100 is detachably connected to the second mounting plate 120, and two first mounting portions 150 are provided on the first mounting plate 100, and the two first mounting portions 150 are symmetrically arranged along the center of the width direction of the first mounting plate 100, and the second mounting plate 120 is correspondingly provided with two second mounting portions 160, and the two second mounting portions 160 are arranged along the length direction of the cross plate portion 130, and the spacing between the two second mounting portions 160 is equal to the spacing between the two first mounting portions 150, and the two second mounting portions 160 are respectively connected to the two first mounting portions 150.

[0038] It can be understood that since the spacing between the two second mounting portions 160 is equal to the spacing between the two first mounting portions 150, the installation direction of the second mounting plate 120 on the first mounting plate 100 can be changed, that is, the vertical plate portion 140 can be installed on both sides of the width direction of the first mounting plate 100 without changing the direction of the first mounting plate 100. When the vertical plate portion 140 is installed toward one side of the width direction of the first mounting plate 100, the vertical plate portion 140 can be installed in the left door frame, and when the vertical plate portion 140 is installed toward the other side of the width direction of the first mounting plate 100, the vertical plate portion 140 can be installed in the right door frame. Therefore, the door axis base can be compatible with being installed on the left door frame and the right door frame, and the installation position adaptability is high.

[0039] In some specific embodiments, the first mounting portion 150 is set as a waist-shaped hole, and the second mounting portion 160 is set as a threaded hole. The first mounting portion 150 and the second mounting portion 160 are connected by bolts. Therefore, by adjusting the fixed position of the bolt in the waist-shaped hole, the relative position between the first mounting plate 100 and the second mounting plate 120 can be adjusted, thereby facilitating the adjustment of the swing center position of the door leaf.

[0040] Furthermore, the length direction of the waist-shaped hole is parallel to the width direction of the first mounting plate 100 , so that the door axis base can adjust the relative position between the first mounting plate 100 and the second mounting plate 120 along the width direction of the first mounting plate 100 .

[0041] In some specific embodiments, a limiting groove 170 is provided at the bottom of the first mounting plate 100, and the limiting groove 170 is extended along the width direction of the first mounting plate 100. The limiting groove 170 is used to accommodate the cross plate portion 130, and the limiting groove 170 abuts against both sides of the width direction of the cross plate portion 130 for limiting. Therefore, when assembling the first mounting plate 100 and the second mounting plate 120, it is easier to align and install the first mounting plate 100 and the second mounting plate 120.

[0042] Furthermore, the limiting groove 170 penetrates the first mounting plate 100 along the width direction of the first mounting plate 100 , so that the limiting groove 170 does not interfere with the installation of the vertical plate portion 140 toward both sides of the width direction of the first mounting plate 100 .

[0043] In some specific embodiments, the first mounting plate 100 has an upwardly protruding stamping portion 180, and a limiting groove 170 is formed at the bottom of the stamping portion 180. Thus, the limiting groove 170 is formed by stamping, so that the thickness of the first mounting plate 100 at the position of the limiting groove 170 will not be reduced, thereby ensuring the structural strength of the first mounting plate 100.

[0044] In some specific embodiments, the first mounting plate 100 is provided with a first mounting hole 190 which passes through from top to bottom. The first mounting hole 190 is used to be fixed to the ground or the bottom of the door frame by screws, thereby making the installation of the door axis base more secure.

[0045] In some specific embodiments, the horizontal plate portion 130 is provided with a second mounting hole 200 that passes through from top to bottom, and at least one first mounting hole 190 is aligned with the second mounting hole 200 from top to bottom. The second mounting hole 200 is used to accommodate the screws on the first mounting hole 190 to pass through, so that the screws can simultaneously lock the first mounting plate 100 and the second mounting plate 120 when the first mounting plate 100 is fixed to the ground or the bottom of the door frame, thereby making the first mounting plate 100 and the second mounting plate 120 more stable.

[0046] Furthermore, the second mounting hole 200 is a waist-shaped hole, and the length direction of the first mounting hole 190 is parallel to the length direction of the transverse plate portion 130 , so that the relative position between the first mounting plate 100 and the second mounting plate 120 can be adjusted.

[0047] In some specific embodiments, the bearing assembly 110 includes a support column 210 arranged on the first mounting plate 100, a support sleeve 220 mounted on the support column 210, and a steel ball 230 arranged between the top surface of the support column 210 and the top wall of the support sleeve 220. The top wall of the support sleeve 220 has a through hole 240 passing through from top to bottom. The through hole 240 is used to accommodate the top of the steel ball 230, so that the steel ball 230 can support the rotation of the support sleeve 220, so that the friction resistance of the rotation of the support sleeve 220 is smaller, and then, the swinging of the door leaf is more labor-saving.

[0048] Furthermore, the diameter of the through hole 240 is smaller than the diameter of the steel ball 230 , so that the steel ball 230 can support the support sleeve 220 and prevent the steel ball 230 from escaping from the through hole 240 .

[0049] In some specific embodiments, the vertical plate portion 140 is provided with a plurality of third mounting holes for fixing to the door frame by screws, thereby facilitating the installation of the vertical plate portion 140 on the door frame.

[0050] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
