a two-way closer

Abstract

The invention discloses a bidirectional closer which comprises a base, a rotary shaft, an energy storage spring and a damper, wherein the rotary shaft is rotatably connected onto the base and is provided with a swinging piece, a spring driving mechanism for driving the energy storage spring, and a damping driving mechanism for driving the damper; the swinging piece is connected with a driving piece on a door; a driving groove is formed in the swinging piece; the spring driving mechanism comprises a spring driven cam and a spring seat; the spring driven cam is arranged on the rotary shaft; the spring seat is arranged on the base through a linear sliding structure; the damping driving mechanism comprises a damping driven cam and a damping connecting seat; the damping driven cam is arranged on the rotary shaft; the damping connecting seat can slide along a straight line relative to the base; a damper shell is connected onto the base; and a damping driving face in contact with the damping driven cam is arranged on the damping connecting seat. The bidirectional closer enables a lock latch to be smoothly locked in a keyhole at the final stage of closing the door, so that the door can be closed in a complete autonomous manner.

Description

technical field [0001] The invention relates to a closer used on a door, in particular to a two-way closer. Background technique [0002] The closer is used in the door, and its function is to provide damping when the door is opened, and to provide power and let the door close slowly when closing the door. The existing closers can only be opened in one direction, corresponding to a door that opens to the left or to the right, a corresponding closer must be used. In practical applications, since the opening direction of the door is determined according to the specific structure of the building, there is uncertainty. Therefore, when installing the closer, the opening direction of the door must be known in advance. It is obviously not convenient to count the number of doors that open in each direction, and then purchase the corresponding left opener and right opener for installation, and it is usually difficult to determine the specific quantity. Generally, the amount of vario...

In practical applications, since the opening direction of the door is determined according to the specific structure of the building, there is uncertainty. Therefore, when installing the closer, the opening direction of the door must be known in advance. It is obviously not convenient to count the number of doors that open in each direction, and then purchase the corresponding left opener and right opener for installation, and it is usually difficult to determine the specific quantity. Generally, the amount of various closers is estimated However, it is easy to cause waste when purchasing; and the closer needs to be replaced due to damage during use. Since the type of damaged closer cannot be determined in advance, it is also difficult to prepare a backup closer in advance.
