Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Please refer to fig. 1-6, a one-way buffering belt pulley buffering structure, including the rotation axis 2 in belt pulley body 1 and the belt pulley body 1, the internally mounted of belt pulley body 1 has the adapter sleeve 6, the inside sliding connection of adapter sleeve 6 has the traveller 5, install limiting plate 3 on the traveller 5, install on the rotation axis 2 and stretch out board 4, stretch out board 4 and be used for conflicting limiting plate 3, still be provided with spout 8 on the limiting plate 3, traveller 5 sliding connection is in the inside of spout 8, still install second spring 9 on the limiting plate 3, second spring 9 is connected with the traveller 5, second spring 9 is used for driving limiting plate 3 to reset.
In this embodiment: the motor corotation stops, and the electric current in the coil changes, can produce the electromotive force opposite with the applied voltage that stops this electric current change, because the electric current of coil can not be sharply bent, and the effect of reverse electromotive force causes the reversal, and then leads to the motor can drive belt pulley body 1 and reverse, probably influences the operation of other parts, consequently the device is through the internally mounted of belt pulley body 1 has limiting plate 3.
Unidirectional buffering: according to fig. 2, 2 fixed mounting of rotation axis are inside the device, and it is rotatory through motor drive belt pulley body 1, utilize limiting plate 3 of belt pulley body 1 internal to contradict on stretching out board 4, because limiting plate 3 is the slope installation, the lower terminal surface of limiting plate 3 can contradict at the up end that stretches out board 4, and then limiting plate 3 receives the extrusion back that stretches out board 4, upwards slides for it can not influence belt pulley body 1 and drive the limiting plate 3 rotatory to stretch out board 4.
After the motor stall, its motor spindle can reverse to this driving pulley body 1 reversal, as shown in fig. 2, when pulley body 1 is rotatory to keeping away from limiting plate 3, through the conflict of stretching out board 4 in one side of limiting plate 3, and then stretch out board 4 spacing limiting plate 3 for limiting plate 3 and pulley body 1 can not rotate, with this unidirectional rotation who realizes pulley body 1.
Subsequently according to 4 show, in order to avoid stretching out board 4 and being damaged by extrusion deformation, set up limiting plate 3 into sliding connection on traveller 5, when stretching out board 4 and contradict when the left side of limiting plate 3, slide through limiting plate 3 looks right side, utilize traveller 5 sliding connection in the inside of spout 8, and cushion the shock attenuation through traveller 5 compression second spring 9 for the device passes through the cooperation of traveller 5 and spout 8, has realized that belt pulley body 1 can one-way buffering when the reversal.
The inside of limiting plate 3 is provided with piston groove 11, and the inside sliding connection of piston groove 11 has piston board 12, offers the through-hole 13 that is used for the circulated air on the piston board 12, still installs transfer line 10 on the piston board 12, and transfer line 10 runs through piston groove 11 and connects on traveller 5, and the inside of adapter sleeve 6 still installs first spring 7, and first spring 7 is connected with traveller 5, and first spring 7 is used for driving traveller 5 to reset.
Slow buffering: when the reversing speed of the belt pulley body 1 is too high, the belt pulley body 1 can drive the limiting plate 3 to quickly strike the extending plate 4, although the sliding column 5 connected to the limiting plate 3 is connected to the inside of the sliding groove 8 in a sliding mode to compress the second spring 9 for shock absorption, when the force of the limiting plate 3 striking the extending plate 4 is too large, the sliding column 5 can directly compress the second spring 9 to limit, and therefore the buffering shock absorption of the sliding column 5 and the second spring 9 is disabled;
therefore, through setting up piston plate 12 in the inside of limiting plate 3, through piston plate 12 sliding connection in the inside of piston groove 11, as shown in fig. 4, when limiting plate 3 atress slided to the right side, through piston plate 12 sliding connection in the inside of piston groove 11, because the through-hole 13 diameter of seting up on piston plate 12 is limited, and then the volume of the inside circulation of air through-hole 13 of piston groove 11 is invariable, consequently, the speed that leads to piston plate 12 sliding connection in the inside of piston groove 11 can keep even, thereby make the device through setting up piston plate 12 and through-hole 13, even buffering has been realized, avoid the effect that the buffering realized, the one-way buffering effect of the device has further been improved.
