Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] Please refer to figure 1 and figure 2 As shown, it shows the specific structure of the first embodiment of a buffer device for a shower room door of the present invention, including a metal block 10, a cylinder 20, a magnetic ring 30 and a piston 40, wherein:
[0022] Described metal piece 10 is fixed on the door 1, and described cylinder 20, magnetic ring 30, piston 40 are all fixed on the door frame 2, and the left end of this cylinder 20 offers a threaded hole, and a left end air flow regulating cover 50 passes through this threaded hole and The left end of the cylinder 20 is threaded, and the threaded hole of the cylinder 20 is sealed. To ensure the tightness, the left end airflow adjustment cover 50 is covered with a rubber ring 51, and the right end of the cylinder 20 is also provided with a threaded hole, and a right airflow adj...

The invention discloses a buffer device for a shower room door. The buffer device comprises a metal block, a cylinder, a magnetic ring and a piston, wherein the metal block is fixedly arranged on a door; the cylinder, the magnetic ring and the piston are fixedly arranged on a door frame; a left opening of the cylinder is sealed through a left air flow adjusting cover; a right air flow adjusting cover is arranged at a right opening of the cylinder; an air flow passage for circulating air is arranged between the right air flow adjusting cover and the right opening of the cylinder; the piston is arranged in a cavity of the cylinder and the cavity of the cylinder is divided into a left section and a right section which are isolated from each other by the piston; the magnetic ring is attached to the right side of the piston; and when the door is in a closed state, the metal block is positioned in the left lower space of the piston. Thus, according to the buffer device provided by the invention, buffer force can be automatically adjusted according to moment of inertia after the door is stressed; even if the door is closed with over-large force, the phenomenon that the door bounces can be avoided; and the buffer device does not produce contact stress with the shower room door, so that the service life is prolonged, and the buffer effect is improved.
Description
technical field [0001] The invention relates to a buffer device, in particular to a buffer device for a shower room door. Background technique [0002] In order to avoid the collision between the door and the door frame when the shower door is opened or closed, which will affect the service life of the shower door, a buffer device will be installed on the shower door. Existing shower room door buffer device mainly contains spring automatic reset type and damping rod type, also has to adopt anti-collision rubber strip as buffer device. However, the above three existing buffering forms all belong to forced elastic buffering, and their buffering strength cannot be adjusted according to the moment of inertia of the door after being stressed, and the phenomenon of door rebound often occurs, and these existing buffering devices are all contact buffers. Type operation, the service life of the buffer device is limited. Contents of the invention [0003] Aiming at the deficiencie...
