Description

Mechanical Buffer and Its Applied Shower Room Sliding Door

technical field

The invention relates to a mechanical buffer and a sliding door of a shower room applied thereto.

Background technique

At present, shower room sliding doors are widely used in the furniture and bathroom industry. In order to reduce the collision noise and damage caused by collisions when doors and windows are opened and closed, people add a plastic hydraulic buffer to the shower room sliding door, but the plastic parts If the hydraulic buffer is used for a long time, it will leak liquid and make the buffer invalid, and the hydraulic buffer needs frequent inspection and maintenance, and has disadvantages such as low service life and unstable quality.

Contents of the invention

The purpose of the present invention is to provide a mechanical buffer with simple structure, convenient assembly, long service life, reliable operation and good buffering effect.

In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:

A mechanical buffer, including a base and a sliding frame that can slide in the base, a one-way rotation damper is installed on the sliding frame, and it is characterized in that: the one-way rotation damper includes a gear, a damping block , mandrel and one-way bearing, there is a concave hole in the middle of the gear, the damping block is inserted into the concave hole, damping oil is filled between the outer wall of the damping block and the inner wall of the concave hole of the gear, the bearing hole is set on the damping block, and the one-way bearing sleeve into the bearing hole, one end of the mandrel is inserted into the one-way bearing, and the other end is installed and locked on the sliding frame. extension spring;

When the sliding frame is pushed along the direction of free rotation of the one-way bearing, the gear and the damping block do not produce resistance. At this time, the extension spring is stretched, and the extension spring acts on the pulling force of the sliding frame to limit the moving speed of the sliding frame;

When the sliding frame is pushed in the direction where the one-way bearing is locked, the gear and the damping block rotate relatively. At this time, the resistance generated by the rotation of the damping oil between the gear and the damping block limits the moving speed of the sliding frame.

The above technical scheme can be further improved through the following measures:

The sliding frame is a rectangular frame including a left side, a right side, a front connecting column and a rear connecting column. A shaft hole is provided on the side, and the rotating shaft is rotatably installed in the shaft hole.

The seat body is box-shaped and includes a top wall, a left side wall, a right side wall, a front end wall and a rear end wall, the rack is arranged inside the top wall, and a horizontal A chute, the sliding frame spans between the left side wall and the right side wall of the seat body and the left side of the sliding frame is slidably embedded in the chute on the left side wall of the seat body, the right side of the sliding frame can Slidably embedded in the chute on the right side wall of the seat body, one end of the tension spring is fixed on the rear end wall of the seat body and the other end is hooked to the rear connecting column of the sliding frame.

The one-way rotary damper also includes an end cover, and the end cover passes through the mandrel to cover the concave hole of the gear.

The gear concave hole is a round hole, and the cross section of the damping block is in the shape of a waist plate with a part of the circular arc cut off symmetrically on the circumference relative to the center line, including two parallel side walls and two arc-shaped walls connecting the ends of the two side walls, The two arc-shaped walls cooperate with the inner wall of the gear concave hole.

The front connecting column of the sliding frame is hinged with a swing arm, which is matched with the outer part and driven by the outer part.

The chute of the side wall and the right side wall includes parallel upper and lower walls and left and right arc walls connecting the ends of the upper and lower walls. There is a locking concave hole on the lower right of the shaped wall. When the swing arm is driven to slide by the outer part, each guide column of the swing arm presses against the lower side wall of the corresponding chute respectively and slides horizontally under the guidance of the lower side wall. When the swing arm When each guide column of the arm enters the right arc-shaped wall from the lower side wall, the swing arm starts to overturn so that the locking column enters the locking concave hole, and finally locks the swing arm.

Another object of the present invention is to provide a sliding door for a shower room. The sliding door for a shower room has a good cushioning effect, which can reduce the impact noise when the door and window are opened and closed, and avoid easy damage due to frequent collisions.

In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:

A sliding door for a shower room, comprising a frame and a door panel, the door panel is slidably embedded in the frame, characterized in that: a mechanical buffer is provided on the top of the frame, and the mechanical buffer includes a seat and a seat that can slide in the seat The moving sliding frame, the seat body is fixed on the top of the frame, and the one-way rotating damper is installed on the sliding frame, and the one-way rotating damper includes a gear, a damping block, a mandrel and a one-way bearing, and the middle part of the gear There is a concave hole, and the damping block can be rotatably inserted into the concave hole.
