A bidirectional damper for a shower door, comprising a mounting frame, a tension spring, a damping cylinder, a first coupling member, a second coupling member and two clamping members;
- wherein
- the mounting frame comprises a first frame plate and a second frame plate with opposite main surfaces, wherein the first frame plate and the second frame plate are connected by a connecting plate and two fixing blocks, the first frame plate, the second frame plate and the connecting plate all have strip plate bodies extending along a length direction of the mounting frame, the first frame plate and the second frame plate are spaced apart along a width direction of the mounting frame and are parallel to each other, the two fixing blocks are positioned at two ends of the mounting frame in the length direction, the connecting plate comprises a substantially horizontal main body section and two extension sections, and the two extension sections are connected to two ends of the main body section in a length direction of the main body section;
- the first frame plate, the second frame plate and the two fixing blocks define a mounting cavity, the connecting plate is configured to divide the mounting cavity into an upper cavity and a lower cavity, the upper cavity is located above the connecting plate, the lower cavity is located below the connecting plate, and a cylinder body of the damping cylinder is fixed in the upper cavity;
- the connecting plate is provided with two guide grooves extending through the two extension sections respectively, the two guide grooves extend along the length direction of the mounting frame on the extension sections, the two clamping members are respectively corresponding to the two guide grooves, and the respective clamping member is slidably mounted in the corresponding guide groove;
- an outer end of each of the two extension sections is bent downwards to form a vertical positioning plate, each guide groove extends from the center of the corresponding vertical positioning plate to the main body section, a first cover plate and a second cover plate are respectively provided at two ends of the main body section, the damping cylinder is placed in a space defined by the first cover plate and the second cover plate, and is located in the middle of the upper cavity;
- the bidirectional damper is characterized in that,
- the cylinder body of the damping cylinder is a dual-cavity cylinder body, and two cylinder cavities of the dual-cavity cylinder body are arranged in parallel, axes of the two cylinder cavities are parallel to each other, while openings of the cylinder cavities face toward opposite directions, the two cylinder cavities correspond to a first piston rod and a second piston rod respectively, and, the first piston rod and the second piston rod are parallel to each other;
- or,
- the damping cylinder is composed of two separate parallel cylinder bodies which are arranged side by side with heads being adjacent to tails, the two cylinder bodies correspond to the first piston rod and the second piston rod respectively, and the first piston rod and the second piston rod are parallel to each other.
