Detailed Description

Example 1

As shown in fig. 1, the electric retractable door roller disassembling tool provided in this embodiment includes a threaded rod 1, a threaded sleeve 2, an articulated arm 3, pulling claws 4 and a locking member 5, wherein one end of the threaded rod 1 is processed with a connecting end 11, the other end is processed with a thimble end 12, the threaded sleeve 2 is connected to the threaded rod 1 in a threaded manner, fixing lugs 21 are processed on the side walls of both sides of the threaded sleeve 2, each fixing lug 21 is hinged to the corresponding pulling claw 4 through the articulated arm 3, one end of the articulated arm 3 is connected to the fixing lug 21 through a bolt 31, the other end is connected to the middle part of the pulling claw 4 through a bolt 31, by providing the articulated arm 3, the distance between the two pulling claws 4 can be conveniently adjusted to adapt to the roller disassembly with different sizes, a pulling hook 41 is processed on the end of the pulling claw 4 close to the thimble end 12, the pulling hooks 41 of the two pulling claws 4 are oppositely arranged, a threaded hole axially perpendicular to the threaded rod 1 is processed on the pulling hook 41, install detachable retaining member 5 in the screwed hole, retaining member 5 includes screw rod 51 and spacing hook 52, spacing hook 52 is fixed at the screw rod 51 tip. The limiting hook 52 is arc-shaped, and the limiting hook 52 is bent towards the corresponding pull claw 4.

In order to facilitate the rotation of the threaded rod 1, the cross section of the connecting end 11 is in a regular hexagon shape so as to adapt to the contour of a wrench, and the wrench is rotated to drive the threaded rod 1 to rotate.

Example 2

In this embodiment, the same as embodiment 1, as shown in fig. 2, only the connecting end 11 is provided with a through mounting hole 13, and when in use, a turning handle can be mounted in the mounting hole 13, and the turning of the threaded rod 1 is controlled by the turning handle.

The utility model discloses a use method is:

when the device is used, as shown in fig. 3, the screw rod 51 is rotated according to the wall thickness of the roller, the distance between the limiting hook 52 and the inner wall of the pulling claw 4 is adjusted to be slightly larger than the wall thickness of the roller, then the thread bushing 2 is rotated to be close to the thimble end 12, then the pulling hook 41 of the pulling claw 4 is hooked on the roller to be disassembled, at the moment, the pulling hook 41 hooks the back of the roller, the limiting hook 52 hooks the inner wall of the roller, a J shape matched with the shape of the roller is formed by the pulling claw 4, the pulling hook 41 and the limiting hook 52, then the threaded rod 1 is rotated to enable the thimble end 12 to be contacted with the rotating shaft, and then the threaded rod 1 is rotated through the connecting end 11 to enable the thread bushing 2 to move towards the connecting end 11 for pulling out the roller from the rotating shaft.

If a roller with a larger diameter is encountered, the included angle between the two pulling claws 4 is increased, as shown in fig. 4, at this time, the pulling hook 41 is opened, and at this time, the inner wall of the roller can be hooked by the arc-shaped limiting hook 52, so that the pulling hook 41 is prevented from falling off from the roller, and the roller dismounting efficiency is ensured.

If a roller with a large wall thickness is encountered, the locking part 5 can be replaced, and the limiting hook 52 with a longer length is replaced, as shown in fig. 5, so that the locking part 5 can be stably hung on the roller in cooperation with the pull claw 4.

The locking piece 5 can be detached when the pull claw 4 is matched with the roller conveniently, and the roller is directly hooked by the drag hook 41.
