[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-4 As shown, a circular flange lead screw support includes a housing 100, a cavity 200 cut into the interior of the housing 100, and a mounting mechanism disposed at one end of the housing 100 for limiting the installation of the bearing. It also includes a reset mechanism disposed inside the cavity for releasing the bearing from the limiting position. The mounting mechanism includes a stop block 108. A diffuser 300 is bolted to one end of the housing 100, improving the ease of connection between the lead screw and the motor. A fixing ring 101 is welded to the inner wall of the cavity 200. An external thread 102 is cut on the outer side of the fixing ring 101. A rotating ring 103 is threaded onto the outer side of the external thread 102. A mounting base 104 is rotatably connected to the outer side of the rotating ring 103. Multiple slots 400 are cut on the outer side of the 4. A sealing ring 500 is pasted on the inner wall of the slot 400. The sealing ring 500 seals the cavity 200 while ensuring the friction between the mounting base 104 and the cavity 200. A rotating shaft 105 is rotatably connected to one end of the mounting base 104. A roller 106 is rotatably connected to the middle position of the rotating shaft 105. Multiple square holes 107 are evenly cut on the inner wall of the housing 100. The stop block 108 is slidably connected to the inner wall of the square hole 107. A drive plate 600 is welded to one end of the mounting base 104. The drive plate 600 drives the rotating ring 103 to rotate. A spring washer 700 is rotatably connected to the inner wall of the drive plate 600. The spring washer 700 uses elasticity to prevent the spring washer 700 from reversing.

[0031] The reset mechanism includes a reset spring 202. One end of the stop block 108 is fixed to a side plate 201 by bolts. The reset spring 202 is fixed to the middle position of the side plate 201 by bolts. A limit frame 203 is welded above the square hole 107. The limit frame 203 limits the movement direction of the stop block 108. One side of the stop block 108 is cut with a bevel 204. The bevel 204 contacts the roller 106, thereby pressing the stop block 108. A rubber pad 800 is pasted on the outer wall of the housing 100. The rubber pad 800 protects the housing 100 and reduces the impact damage to the housing 100. A bearing outer ring 302 is slidably connected inside the housing 100. Multiple cylindrical rollers 303 are rotatably connected to the inner wall of the bearing outer ring 302. One side of the cylindrical rollers 303 is rotatably connected to the bearing inner ring 301.

[0032] In this embodiment, by turning the drive plate 600, the drive plate 600 drives the rotating ring 103 to rotate. Under the transmission action of the external thread 102, the rotating ring 103 rotates and moves forward, thereby driving the mounting base 104 to move forward. The mounting base 104 drives multiple rollers 106 to move forward synchronously. During the forward movement of the rollers 106, the inclined surface 204 presses down on multiple stops 108. The stops 108 extend from the square hole 107, realizing the quick installation of the bearing. When it is necessary to disassemble the bearing, similarly, by reversing the drive plate 600, under the elastic action of the return spring 202, the stops 108 retract from the square hole 107, releasing the limitation on the bearing. This allows the bearing to be quickly disassembled during use of the round flange screw support, improving the convenience of maintenance of the round flange screw support and ensuring the efficiency of maintenance.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
