[0032] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figures 1 to 3As shown, the utility model is an adjustable large load-bearing pivot base, including a base 10, and a fixed panel 20 assembled and connected to the upper end of the base 10; a transversely arranged adjusting screw 30 is provided on the base 10, and a threaded movable block 40 is provided on the outer side of the adjusting screw 30, and a shaft sleeve 50 is fixed at the upper end of the movable block 40, and the upper end of the shaft sleeve 50 is exposed from the fixed panel 20 for easy connection with the door shaft; a fastening nut 60 is sleeved on the tail end of the adjusting screw 30, and a vertically penetrating set screw 70 is provided on the fixed panel 20.

[0035] In this embodiment, the base 10 and the fixed panel 20 are connected as a whole by butt welding and installed in the door frame. This installation connection method is more stable and can meet the needs of large load-bearing door leaves. The door shaft is installed in the shaft sleeve 50 and rotates to realize the rotation of the door leaf. The adjusting screw 30 is rotated, and the movable block 40 moves back and forth along the adjusting screw 30 in the base 10 under the drive of the thread, thereby adjusting the position of the shaft sleeve 50 and the door shaft, and the operation is convenient. After the position adjustment of the door shaft is completed, the set screw 70 is screwed in, and the lower end of the set screw 70 abuts against the fastening nut 60, thereby limiting the rotation of the adjusting screw 30, so as to fix the position of the movable block 40 and the door shaft.

[0036] Specifically, the base 10 includes a U-shaped support base 11 and a connecting platform 12 integrally formed on one side of the support base 11. The connecting platform 12 is horizontally arranged to facilitate connection with the fixed panel 20. The adjusting screw 30 passes through the support base 11 horizontally, and the tail end of the adjusting screw 30 is arranged at the lower end of the connecting platform 12. A countersunk hole 111 is penetrated on one side of the support base 11 away from the connecting platform 12, and a through hole 112 is penetrated on the other side of the support base 11. The countersunk hole 111 and the through hole 112 are horizontally aligned. The adjusting screw 30 passes through the countersunk hole 111 and the through hole 112 in sequence, and the countersunk hole 111 is arranged to accommodate the head of the adjusting screw 30. A guide groove 113 is recessed at the bottom of the support base 11, and the guide groove 113 extends along the length direction of the adjusting screw 30. A guide block 41 extends from the lower end of the movable block 40, and the guide block 41 is slidably connected in the guide groove 113 to limit the movable block 40 to always slide linearly in the base 10 to adjust the position of the door shaft.

[0037] Furthermore, in order to fix the base 10 and the fixed panel 20, the support base 11 extends a connecting block 114 upward, and the fixed panel 20 is provided with a connecting hole 21. The cross-sectional shapes of the connecting block 114 and the connecting hole 21 are both rectangular. The connecting block 114 is inserted into the connecting hole 21 to achieve the connection and alignment between the base 10 and the fixed panel 20; a circular hole 121 is penetrated through the connecting platform 12, and a pin hole (not shown) is recessed at the bottom of the fixed panel 20 and is aligned with the circular hole 121 up and down. The radius of the circular hole 121 is consistent with that of the pin hole, and a pin shaft 80 is inserted into the circular hole 121 and the pin hole to reinforce the connection between the fixed panel 20 and the base 10.

[0038] Specifically, a mounting platform 42 extends from the upper end of the movable block 40, and a mounting hole 421 is provided on the mounting platform 42, and the shaft sleeve 50 is fixed in the mounting hole 421. In addition, in order to ensure the adjustment of the door shaft, a limiting hole 22 is penetrated on the fixed panel 20, and the limiting hole 22 is specifically arranged above the guide groove 113. When the movable block 40 moves along the adjusting screw 30, the mounting platform 42 moves in the limiting hole 22.

[0039] Specifically, a washer 71 and a retaining ring 72 are sleeved on the tail end of the adjusting screw 30 . The washer 71 and the retaining ring 72 are respectively arranged at both ends of the fastening nut 60 to prevent the fastening nut 60 from loosening and falling off.

[0040] Specifically, the fixed panel 20 is provided with an assembly hole 23 for structural connection, and bolts are screwed into the assembly holes 23 to install the fixed panel 20 and the base 10 into the door frame.

[0041] The assembly sequence of the adjustable large load-bearing pivot base involved in the utility model is as follows:

[0042] 1. The shaft sleeve 50 is pressed into the mounting hole 421 on the movable block 40 .

[0043] 2. The movable block 40 is placed between the fixed panel 20 and the base 10 , and the guide piece at the lower end of the movable block 40 is inserted into the guide groove 113 in the base 10 .

[0044] 3. The panel 20 and the base 10 are fixed by plugging and assembling the connection block 114 and the connection hole 21, and the panel 20 and the base 10 are fixed by butt welding.

[0045] 4. Insert the pin shaft 80 into the circular hole 121 and the pin hole to reinforce the fixed panel 20 and the base 10.

[0046] 5. Screw in the adjusting screw 30 , which passes through the countersunk hole 111 , the movable block 40 and the through hole 112 in sequence. Screw the adjusting screw 30 to adjust the position of the movable block 40 .

[0047] 6. Assemble the washer 71 , the fastening nut 60 and the retaining ring 72 at the tail end of the adjusting screw 30 , and finally screw in the set screw 70 to lock the adjusting screw 30 .

[0048] 7. Install the base 10 and the fixed panel 20 onto the door leaf frame, and install the door shaft onto the shaft sleeve 50.

[0049] Compared with the prior art, the adjustable large-load-bearing pivot base involved in the utility model can meet the needs of large-load-bearing door leaves and has the function of conveniently adjusting the door shaft; specifically, a threaded movable block 40 and an adjusting screw 30 are provided, and the movable block 40 is used to connect the door shaft. Rotating the adjusting screw 30 can adjust the position of the movable block 40 and then adjust the distance of the door shaft, and the adjustment is convenient; in addition, a locking screw 70 is provided to limit the rotation of the adjusting screw 30, thereby fixing the movable block 40 and the door shaft position; in addition, a base 10 and a fixed panel 20 for assembling the movable block 40 and the adjusting screw 30 are also provided, and the base 10 and the fixed panel 20 are installed on the door frame to provide support for the movable block 40 and the door shaft. The structure is more stable and can meet the needs of large-load-bearing door leaves.
