[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] like Figure 1-Figure 6 The figure shows a door leaf pivot base disclosed in the utility model. The door leaf pivot base can be used to cooperate with a door leaf rotating shaft assembly to achieve the installation of the door leaf.

[0029] See also Figure 1 The door leaf pivot base of this embodiment includes a fixing seat 1, an adjusting block 2, and an adjusting screw 3. The fixing seat 1, the adjusting block 2, and the adjusting screw 3 are all made of materials with increased hardness, such as stainless steel, aluminum alloy and other metal materials.

[0030] The fixing base 1 comprises a main body 11 and two wing parts 12 (see Figure 2 ), the top surface of the main body 11 has a sliding groove 111 arranged along the length direction, and one end of the sliding groove 111 has a snap-in groove 112. Specifically, the main body 11 can be in the shape of a groove with an open top, for example, it can be formed by stamping and bending a metal plate. The two wings 12 are respectively in the shape of flat plates and connected to the two sides of the width direction of the main body 11, that is, the two wings 12 protrude from the two side walls of the width direction of the main body 11, each wing 12 has a mounting hole 121, and the door leaf pivot base is mounted on the door frame by screws passing through the mounting holes 121. In order to avoid the screws being exposed, the above-mentioned mounting holes 121 can be countersunk holes.

[0031] The adjusting block 2 is in the shape of a rectangular parallelepiped as a whole, and is provided with a vertical shaft hole 21 and a horizontal threaded hole 22, and the adjusting block 2 is assembled in the sliding groove 111 in such a manner that the shaft hole 21 faces upward and the threaded hole 22 faces the clamping groove 112. In this embodiment, the width of the adjusting block 2 is adapted to the width of the sliding groove 111, for example, the width of the adjusting block 2 is slightly smaller than the width of the sliding groove 111, so that the adjusting block is easily assembled in the sliding groove 111, and can move along the length direction of the sliding groove 111 under the limitation of the two side walls of the sliding groove 111. The vertical and horizontal directions are the states after the door leaf pivot base is installed in the door frame.

[0032] The adjusting screw 3 is assembled on the clamping groove 112 and is threadedly connected to the threaded hole 22 of the adjusting block 2, and when the adjusting screw 3 is driven to rotate, it drives the adjusting block 2 to slide in the sliding groove 111. Under the limit of the clamping groove 112, the adjusting screw 112 does not move axially during the rotation process, but only drives the adjusting block 2 threadedly connected thereto to move axially.

[0033] During assembly, first put the adjusting block 2 into the sliding groove 111 of the main body 11, and make the end of the adjusting block 2 with the threaded hole 22 face the end of the sliding groove 111 with the snap-in groove 112, then insert the adjusting screw 3 into the snap-in groove 112 in the vertical direction and snap-in with the main body 11 to achieve preliminary fixation of the adjusting screw 3 in the horizontal direction, then insert the adjusting screw 3 into the threaded hole 22 of the adjusting block 2 in the horizontal direction and threadedly connect with the adjusting block 2, and adjust the relative position of the adjusting block 2 and the adjusting screw 3 by rotating the adjusting screw 3, thereby achieving horizontal movement of the adjusting block 2 in the sliding groove 111 to adjust the relative position of the rotating shaft 4 connected to the axial hole 21 of the adjusting block 2, and the base is assembled on the door frame by screws passing through the mounting hole 121 of the wing 12, thereby achieving connection between the base and the door frame profile 5.

[0034] In the above-mentioned door leaf pivot base, since the main body 11 is fixed in a "hanging" manner by the two wings 12, the bottom of the main body 11 does not need to be attached to the bottom of the door frame installation groove, so that the installation of door frames with installation grooves of different depths can be met. At the same time, the two wings 12 protrude from both sides of the main body 11 in the width direction, so that the door leaf pivot base can meet the installation requirements of door frames with installation grooves of different widths.

[0035] In one embodiment of the present invention, in order to improve the convenience of production, the two wings 12 are integrally arranged with the main body 11 (see Figure 3 ), for example, the main body 11 and the wing 12 are formed by stamping and bending a unified metal plate, and the upper surface of the wing 12 is flush with the top surface of the main body 11, thereby ensuring that the top surface of the main body 11 and the top surface of the wing 12 are in the same horizontal plane to form a T-shaped base; specifically, in other embodiments, the two wings 12 can also be integrally connected at the middle position on both sides of the main body 11.

[0036] In one embodiment of the present invention, the fixing base 1 includes a bottom plate 13 (see Figure 4 and Figure 5 ), the length of the bottom plate 13 matches the length of the main body 11, and the bottom plate 13 is welded to the bottom of the main body 11; the two wings 12 are respectively formed by the parts of the bottom plate 13 protruding from the two side surfaces in the width direction of the main body 11, and the two wings 12 protrude from the two side surfaces in the width direction of the main body 11 with the same width, thereby ensuring that the connection area between the two wings 12 and the door frame profile 5 is the same, thereby improving the connection stability between the base and the door frame profile 5, and the bottom plate 13 is arranged below the main body 11 to form an inverted T-shaped base (see Figure 6 ), the T-shaped base and the inverted T-shaped base can at least be applicable to two or more door frame profiles 5, thereby increasing the application range of the pivot base.

[0037] In one embodiment of the utility model, the distance between the outer edges of the two wings 12 is smaller than the width of the door frame, and the dimension of each wing 12 along the length direction of the door frame is smaller than or equal to the dimension of the main body 11 along the length direction of the door frame, thereby realizing the assembly of the base and the door frame and improving the fit between the base and the door frame.

Specifically, the limiting part 113 is formed by pressing the side wall of the main body 11 inward as a whole, and when the wing 12 is integrally connected to the main body 11, for the convenience of production, the position where the main body 11 is connected to the limiting part 113 does not protrude from the two wings 12 on the side; the adjustment block 2 is provided with a clearance groove matched with the limiting part 113, and when the adjustment block 2 is assembled to the sliding groove 111, the two limiting parts 113 are respectively embedded in the clearance groove, and the limiting part 113 guides the axial movement of the adjustment block 2 in the sliding groove 111. Specifically, the length of the clearance groove is matched with the length of the limiting part 113, so as to reduce the production cost while realizing the limitation of the adjustment block 2 and improving the stability of the connection between the adjustment block 2 and the main body 11.

[0039] In one embodiment of the utility model, the door leaf pivot base also includes a sleeve 23, the adjustment block 2 is provided with a vertical connecting groove, the sleeve 23 is assembled in the connecting groove in an interference fit manner to form an axis hole 21, the sleeve 23 is first connected to the adjustment block 2, and then the adjustment block 2 is assembled in the sliding groove 111 of the main body 11, and the sleeve 23 is inserted through the rotating shaft 4 to realize the rotational connection between the door leaf and the door frame.

[0040] In one embodiment of the utility model, the bottom of the sliding groove 111 has a waist-shaped hole that penetrates the fixed seat 1 and is arranged along the length direction of the fixed seat 1. The width of the waist-shaped hole is greater than or equal to the inner diameter of the shaft hole 21, and when the adjusting block 2 slides in the sliding groove 111, the positive projection of the shaft hole 21 is always in the waist-shaped hole. In other embodiments, when the wing 12 is composed of a bottom plate 13 connected to the bottom of the main body 11 and protruding from both sides of the main body 11, the bottom plate 13 is also provided with a through hole connected to the sliding groove 111, so that when the length of the rotating shaft 4 is too long, it can extend out of the waist-shaped hole and the through hole to connect with the base, thereby improving the diversity of the connection between the base and the rotating shaft 4.

[0041] In one embodiment of the utility model, the adjusting screw 3 includes an axially arranged clamping section and a threaded section, the clamping section has a clamping interface, and the adjusting screw 3 is threadedly connected to the adjusting block 2 by embedding the clamping groove 112 through the clamping interface and inserting the threaded section into the threaded hole 22 of the adjusting block 2, thereby ensuring the tight clamping of the adjusting screw 3 and the clamping groove 112, thereby realizing stable adjustment of the adjusting screw 3 on the adjusting block 2 and improving the stability of the overall structure of the base.
