[0041] Please refer to the appendix Figures 1-8 , which shows a detachable buffer for a pulley provided by an embodiment of the present application, including a movable rod 1, a buffer movable part 2, a front pulley connecting member 4, a front pulley member 3, a rear pulley connecting member 5, and a rear pulley member 6.

[0042] The cross-section of the movable rod 1 is "U" shaped. The buffer movable part 2 is slidably installed inside the movable rod 1 along the length direction of the movable rod 1. The length of the buffer movable part 2 is shorter than the length of the movable rod 1. The buffer movable part 2 can slide inside the movable rod 1. The front pulley connecting member 4 is fixedly connected to the front end of the movable rod 1 by a first bolt. One end of the front pulley connecting member 4 away from the movable rod 1 is hinged with a front pulley member 3. The front pulley member 3 can rotate around the hinge shaft. And a second spring 405 is arranged on the side of the front pulley connecting member 4 facing the front pulley member 3. The second spring 405 makes the front pulley member 3 rotate in the direction away from the front pulley connecting member 4. However, during use, a downward force (the gravity of the door and window) is applied to the bottom of the front pulley member 3, so that the movable rod 1 and the pulley member 3 are kept horizontal, and the second spring 405 is compressed, thereby realizing the function of automatically leveling the pulley component of the pulley buffer. The rear pulley connecting member 5 is fixedly connected to the rear end of the movable rod 1 by a second bolt, and a rear pulley member 6 is fixedly connected to one end of the rear pulley connecting member 5 away from the movable rod 1.

[0043] The front pulley connecting member 4 is connected by a first bolt, and the rear pulley connecting member 5 is connected by a second bolt. When the buffer oil cylinder 201 of the buffer movable part 2 inside the movable rod 1 leaks oil and is damaged, or the first spring 204 is damaged, the front pulley connecting member 4 or the rear pulley connecting member 5 can be removed to replace the buffer movable part 2, thus facilitating maintenance during use.

[0044] In one embodiment, the buffer moving member 2 includes: a buffer oil cylinder 201, a first slider 202, a second slider 203, and a first spring 204.

[0045] The first slider 202 and the second slider 203 are fixedly installed at both ends of the buffer oil cylinder 201 respectively. A first spring 204 is arranged between the first slider 202 and the second slider 203 and is parallel to the axial direction of the buffer oil cylinder 201. The first spring 204 and the buffer oil cylinder 201 cooperate to play a good buffering role, and the buffer oil cylinder 201 can be a two-way telescopic oil cylinder.

[0046] A first shaft member 202a is fixedly arranged on the side surface of the first slider 202, and a second shaft member 203a is fixedly arranged on the side surface of the second slider 203.
