Abstract

The invention discloses a door speed limiter. The door speed limiter comprises a base, a roller and a centrifugal rolling rod, the base body is of a frame structure, the frame structure is composed ofthree rectangular plates, a fluctuation plate is arranged on the inner side of one of the rectangular plates on the two sides, the fluctuation plate is an arc plate with the central axis of a rollerrotating hole as the central axis, and protruding blocks are evenly distributed on the lower surface of the arc plate. a roller body is a circular ring shell with a shaft in the center and an openingin one side, the shaft in the center of the roller is matched with the roller rotating hole in the base, and a centrifugal rolling rod sliding groove is formed in the shaft on the opening side of thecircular ring shell and used for being matched with a centrifugal rolling rod outer shell; and the centrifugal rolling rod body is a rectangular block, and a rotating wheel is arranged at one end of the rectangular block and can rotate around a rotating wheel restraining hole in the rectangular block. The problem that an existing door body fixator cannot restrain the speed of the whole movement process of a door body is solved.

Description

technical field [0001] The invention relates to a door panel movement speed limiter, in particular to a door speed limiter. Background technique [0002] At present, with the improvement of living standards, people's requirements for the quality of life are increasing day by day, and they begin to pay attention to the details of life. In daily life, it is found that in places with abundant wind resources, the door is often opened suddenly or Closing, making a sudden sound or even hurting people, most of the restrictions on the door are currently adding a magnetic retainer behind the door panel to keep the door open. Once the magnetic retainer is separated, the door will be restored. The out-of-control state cannot play a role in restricting the whole process of door panel activity. Contents of the invention [0003] The purpose of the present invention is to provide a door speed limiter, which is used to solve the problem that the existing door body fixer cannot realize t...
