The pin of Fig. 1 can insert the traction belt wheel of Fig. 2.This belt wheel has the hole that is formed at central authorities, this hole basically with the shape complementarity of pin.For the application of mobile shelter or roller shutter, there is gap can not cause damage (supposing that this gap is in the scope of appropriateness) between the pin and the hole of belt wheel.
Tube shaped electric machine of the present invention has the output pin that is suitable for inserting in the hole of drawing belt wheel.This output pin comprises and is installed in pin or the belt wheel and is being formed with the resilient metal member that can prevent the protuberance that slides in the hole of shotpin at belt wheel on pin or the belt wheel.This resilient metal member is suitable for being compressed so that sell in the hole that can insert belt wheel, and is in rigging position automatically after being suitable in the hole of selling out full insertion belt wheel so that anti-shotpin breaks away from belt wheel.
The resilient metal member of using among the embodiment shown in the drawings is modulation steel (harmonic steel) wire piece with suitable shaping.An example of this shaping wire rod before being installed in the cavity of pin of Fig. 3 shown in Fig. 4.Fig. 4 A illustrates three rectangular projections of these parts, and Fig. 4 B illustrates axis side view.
The pin of Fig. 3 after the parts that Fig. 5 is illustrated in Fig. 4 have been installed within it.These parts almost completely are arranged in the cavity of pin.The end of wire rod is outstanding from two side opening side direction of pin, and forms two protuberances.Two eyelets (forming by bent wire) are outstanding from the front portion of pin.
The parts of Fig. 5, that is, wire piece is suitable for radially being compressed by bending.The side surface that this wire piece can be compressed up to its end from pin always is outstanding.Like this, pin freely can be inserted in the hole of belt wheel.In fact, this wire piece is suitable for further being compressed so that it can be installed in the pin.
When in the hole of selling out full insertion belt wheel, as shown in Figure 6, this wire piece (because elasticity of material) is in rigging position automatically, that is, and and the position of Fig. 5; Like this, the protuberance of this parts formation can prevent that shotpin breaks away from belt wheel.
The following describes many favourable but optional aspects of the present invention.
