Embodiment 1

[0026] see Figure 1-Figure 6 , a non-rotating door opening and closing speed limiter, consisting of a bracket 1, a roller 2 and a pendulum 3; the bracket 1 includes a door connecting plate 4 and three roller connecting plates 5, and the roller connecting plate 5 There are three pieces, which are respectively left, middle and right. There is an annular baffle 6 inside the right roller connecting plate 5-1. The main body of the annular baffle 6 is a ring, and two baffles 7 are arranged symmetrically inside the ring. The main body of the roller 2 is a cylinder 7, the left center of the cylinder 7 has a shaft 8, the center of the right side of the cylinder 7 has a major axis 9, and the top of the major axis 9 is provided with a pendulum connection frame 10, and the pendulum connection frame 10 It is two rectangular plates 11, the rectangular plates 11 are perpendicular to the central axis of the major axis 9, the rectangular plates 11 are provided with a pendulum connection hole ...

Abstract

The invention discloses a rotation stopping type door opening and closing speed limiter which is composed of a bracket, a rolling wheel and a pendulum hammer. The bracket comprises a door connecting plate and three rolling wheel connecting plates, an annular baffle is arranged on the inner side of the right side rolling wheel connecting plate, and two baffles are symmetrically arranged in the annular baffle; a rolling wheel main body is a cylinder, the center of the left side of the cylinder is provided with a shaft, the center of the right side of the cylinder is provided with a long shaft, apendulum bob connecting frame is arranged on the top of the long shaft and comprises two rectangular plates, and the rectangular plates are provided with pendulum bob connecting holes; a mass block is arranged at one end of the pendulum bob, and a pendulum bob connecting shaft is arranged at the other end of the pendulum bob; after the speed limiter is installed on the door, the rolling wheel fits the ground; when the door is opened and closed, the friction between the rolling wheel and the ground can drive the rolling wheel to rotate; when the door opening and closing speed exceeds the set speed, the pendulum bob swings outwards under the centrifugal action, the baffles in the annular baffle of the bracket are hooked, the rolling wheel stops rotating, and the door is slowed down. The problem that an existing door is not restricted when the door is half opened / closed is solved.

Description

technical field [0001] The invention relates to a door opening and closing speed limiter, in particular to a rotation-stop type door opening and closing speed limiter. Background technique [0002] At present, with the development of the urbanization process, more and more high-rise residences are being built. Since the floors of high-rise residences are relatively high, convective winds are often encountered when opening windows for ventilation. Therefore, most of the current high-rise residences are in The door is equipped with an electromagnetic suction device to prevent the door from opening and closing at high speed due to convective wind when the door is opened. [0003] However, only the door of the electromagnetic suction device can only play the fixing effect on the door when the door is fully opened, and cannot realize the fixing effect on the door when the door is in a half-open state. Therefore, it is necessary to fix the existing door. The equipment is suppleme...
