BRIEF DESCRIPTION OF THE DRAWINGS
[0018] Figure 1 It is a schematic diagram of the structure of this embodiment;
[0019] Among them, there are a motor 1, a screw rod 2, a slider 3, an insulating part 4, a conductor 5, a conductor spring 6, a hook handle 6a, a hook bend 6b, a reducer 7, a slide rod 8, and a seat 9. DETAILED DESCRIPTION
[0020] like Figure 1 As shown, this embodiment includes a motor 1, a screw rod 2, a nut, a slider 3, an insulating member 4, a conductor 5 and a conductor spring 6.
[0021] The output end of the motor 1 is connected to one end of the screw rod 2, and the motor 1 can drive the screw rod 2 to rotate. Further, the embodiment is also provided with a reducer 7, the output end of the motor 1 is connected to the input end of the reducer 7, and the output end of the reducer 7 is connected to one end of the screw rod 2.
[0022] This embodiment also provides a seat 9, the motor 1 and the reducer 7 are fixed on the seat 9, and the seat 9 is also provided with a bracket for supporting the screw rod 2. The bracket can limit the movement of the screw rod 2 in the horizontal, longitudinal and vertical directions, but cannot limit the rotation of the screw rod 2 around its axis.
[0023] The nut is sleeved on the screw rod 2, and the rotation of the screw rod 2 can drive the nut to slide back and forth on the screw rod 2. One end of the slider 3 is connected to the nut, and the sliding back and forth of the nut can drive the slider 3 to move together. In this embodiment, the nut is embedded in one end of the slider 3, making the overall structure more compact. In other embodiments, the nut can also be connected to the slider 3 by splicing.
[0024] The other end of the slider 3 is connected to one end of the insulating member 4. The movement of the slider 3 drives the insulating member 4 to move. The other end of the insulating member 4 is connected to one end of the conductor 5, and the movement of the insulating member 4 drives the conductor 5 to move. The conductor 5 in this embodiment adopts a thick sheet structure. In other embodiments, the conductor 5 can also adopt a square rod, a round rod or a needle structure.
[0025] In order to make the slider 3 move more smoothly, a slider 8 is also provided in this embodiment. The slider 8 is arranged in parallel with the screw 2, and the slider 8 is also fixed on the seat 9. The slider 3 is sleeved on the slider 8 and can slide back and forth in the length direction of the slider 8. In other embodiments, the slider 8 may not be provided, and a strip-shaped slide groove may be provided, and the slide groove is arranged in parallel with the screw 2, and the slider 3 can slide back and forth in the slide groove. In another embodiment, there is no slider 8 or a slide groove and other structures, and depending on the weight of the slider 3 itself, the rotation of the screw 2 can also realize the movement of the slider 3 back and forth in the length direction of the screw 2.
[0026] The conductor spring piece 6 in this embodiment is made of copper. In other embodiments, iron or other conductor materials may also be used. The two conductor spring pieces 6 are hook-shaped. The hook handles 6a of the two conductor spring pieces 6 are parallel to each other. The two hook handles 6a are respectively used to connect the two ends of the external circuit. The hook bends 6b of the two conductor spring pieces 6 are opposite to each other with a gap. In other embodiments, the two conductor spring pieces 6 may also be arranged in an arc shape. The arc-shaped arch surfaces of the two conductor spring pieces 6 are opposite to each other with a gap.
[0027] The other end of the conductor 5 can be squeezed into and out of the gap under the forward and reverse rotation of the motor 1. When the motor 1 rotates forward, the other end of the conductor 5 is inserted into the gap and squeezes the two conductor springs 6, so that the two conductor springs 6 are conductive. When the motor 1 rotates reversely, the other end of the conductor 5 is separated from the gap, and the two conductor springs 6 are disconnected.
[0028] In order to facilitate the insertion of the other end of the conductor 5 into the gap, the other end of the conductor 5 is chamfered. In other embodiments, the other end of the conductor 5 can also be configured to be needle-shaped or ladder-shaped.
[0029] Since the conductor spring 6 has a certain elasticity, the stability during conduction can be well guaranteed under this structure. Moreover, using two conductor springs 6 to clamp the other end of the conductor 5 can effectively prevent the influence caused by vibration.
[0030] There are two opposite arches on both sides of the gap of the conductor spring piece 6. When the other end of the conductor 5 is squeezed into the gap, it can be squeezed in along the arc. In addition, the conductor spring piece 6 itself has plasticity, so the overall installation accuracy requirement can be reduced.
[0031] Of course, in order to further adjust the alignment of the conductor 5 squeezed into the gap, in other embodiments, a mounting hole perpendicular to the length direction of the screw rod 2 can be provided on the insulating part 4, and a screw is passed through the mounting hole to fix the insulating part 4 to the other end of the slider 3. In this way, the position of the conductive block 5 relative to the gap can be adjusted by changing the position of the screw in the mounting hole.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
