Speed reducing mechanism and winding device thereof

Abstract

The invention provides a speed reducing mechanism. The speed reducing mechanism comprises a shell, a moving part, a rotating piece and a damping piece; wherein the movable piece is movably arranged ona spiral track on the first surface of the shell. The rotating piece is rotatably coupled to the shell, the rotating piece is provided with a second surface opposite to the first surface, the rotating piece comprises an actuating part which is arranged on the second surface and abuts against the moving piece, and when the rotating piece rotates relative to the shell, the actuating part drives themoving piece to move in the spiral track. The damping part is selectively arranged on the rotating piece and corresponds to the speed reduction section of the spiral track, and when the moving pieceenters the speed reduction section, the damping part abuts against the moving piece so as to reduce the rotating speed of the rotating piece relative to the shell. In one embodiment, the speed reducing mechanism is combined with the winding device to form the winding device with a speed reducing function, so that the speed can be properly reduced when the take-up end part is close to the shell.

Description

【Technical field】 [0001] The invention relates to a technology for coiling and pulling wires, in particular to a deceleration mechanism and a wire winding device with speed control of wire coiling. 【Background technique】 [0002] see figure 1 As shown in FIG. 2 , it is a schematic diagram of the relationship between video output and input in a conference room in the prior art. In the prior art, taking meeting room 13 as an example, there are generally multimedia output devices, such as projectors or flat-panel displays, and multimedia input devices, such as computers, DVD players, or portable computers. In this application situation, figure 1 In order to facilitate the connection of the signal input end of the projector 11 with the user's portable computer, signal cables are used as the connection medium. However, because users in different positions in the conference room can be connected to the signal cable, long signal cables must be used. [0003] exist figure 1 Amo...

Problems solved by technology

Although this can ensure that the wire is recycled into the reel device, but when the signal wire is reclaimed, when one end of the wire is closer to the reel device, if you do not pay attention, it is easy to cause the user to be hit by one end of the signal wire, or because of recycling If the speed is too fast, one end of the wire will hit the winding device and make a loud noise that will startle the user
