Description

Technical Field

[0001] The utility model belongs to the field of flip power-off mechanisms, in particular to a flip power-off mechanism for night vision goggles. Background Art

[0002] Night vision goggles are devices that achieve night vision observation based on night vision technology. In actual use, it is necessary to consider the use of night vision goggles in different scenarios. For example, when there is sufficient light during the day, the night vision goggles do not need to work. When night falls, the night vision goggles need to be able to work quickly.

[0003] Therefore, a mechanism is realized in which a night vision goggle can be turned up and not work during the day, and can be turned down and work immediately at night, which has extremely strong practicality and convenience. Utility Model Content

[0004] The utility model aims to provide a night vision goggle flipping and power-off mechanism, which can realize power-off or power-on when the night vision goggle is flipped, and effectively increases the convenience of operation of the night vision goggle.

[0005] The technical solution of the utility model is:

[0006] The utility model discloses a night vision goggle flipping and power-off mechanism, which is composed of a monocular night vision goggle, a connecting seat, a wear-resistant gasket, a clamping handle, an electrode pressing cylinder, an electrode sealing ring, a screw, an electrode screw rod, an electrode contact plate, an electrode contact sheet and a crossbeam.

[0007] The connecting seat and the monocular night vision goggle are an integral whole. The rotating arm of the connecting seat is fixed to the bracket through a clamping handle and can rotate. The wear-resistant gasket is fixed to the rotating arm of the connecting seat and is used to adjust the control damping. The electrode contact plate is fixed to the inner end surface of the rotating arm of the connecting seat. The electrode pressure cylinder is fixed to the clamping handle as an integral whole through screws. The electrode contact plate is fixed to the electrode pressure cylinder through an electrode screw, and the electrode sealing ring is fixed to the electrode pressure cylinder.

[0008] The working principle and beneficial effects of the utility model are as follows:

[0009] The electrode contact plate is connected to the negative pole of the power supply, and the electrode contact piece is connected to the positive pole of the power supply. When the barrel of the monocular night vision goggle rotates, the electrode contact plate rotates accordingly, and the electrode contact piece does not move. When it rotates to a certain angle in the positive direction (such as upward), the electrode contact plate and the electrode contact piece are in contact and conductive, thereby powering the monocular night vision goggle. When it rotates to a certain angle in the reverse direction (such as downward), the electrode contact plate and the electrode contact piece are separated and disconnected, thereby powering off the monocular night vision goggle.

[0010] The night vision goggles do not work when flipped up during the day, but work immediately when flipped down at night, making them extremely practical and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Reference Figure 1-6 The monocular night vision goggles 1 is an imaging component for collecting low-light images. The connecting seat 2 is connected to the monocular night vision goggles 1 as a whole. The wear-resistant gasket 3 is fixed on the cylindrical surface of the rotating arm at one end of the connecting seat 2 to adjust the damping during rotation. The clamping handle 4 is connected to the cross beam 11 as a whole and restricts the connecting seat 2 to the cross beam 11. The connecting seat 2 can rotate on the cross beam 11. The electrode pressing cylinder 5 is connected to the clamping handle 4 as a whole through the screw 7, the electrode sealing ring 6 is connected to the electrode pressing cylinder 5 as a whole, the electrode contact piece 9 is connected to the electrode pressing cylinder as a whole through the electrode screw 8, and the electrode contact plate 10 is fixed in the end surface groove of the connecting seat 2.

[0020] Reference Figure 1-6 , the working principle of the utility model is:

[0021] The electrode screw 8 fixes the electrode contact plate 10 so that the power supply connection wires are welded at the ends of the device respectively. The electrode pressing cylinder 5 is fixed to the pressing handle 4 by screws 7, and the rotation is limited by the groove on the pressing handle 4. The electrode sealing ring 6 is fixed to the electrode pressing cylinder 5, which plays a role of sealing and increasing damping. The electrode contact piece 9 is fixed to the electrode pressing cylinder 5 by the electrode screw 8, and the rotation is limited by the groove on the electrode pressing cylinder 5. The electrode contact plate 10 is fixed to the connecting seat 2.

[0022] When the night vision goggle barrel 1 and the connection seat 2 are in the lowered working state, the electrode contact plate 10 is in contact with the electrode contact piece 9, so the night vision goggle is turned on and in the working state. When the night vision goggle barrel 1 and the connection seat 2 are turned up, the electrode contact plate 10 is driven to rotate together. The electrode contact piece 9 remains stationary, and the electrode contact plate 10 is disconnected from the electrode contact piece 9 when it rotates to a certain angle, so the night vision goggle is disconnected and in the non-working state.

[0023] The power supply connection line can also be adjusted to a signal line, and the power can be cut off when the electrode contact piece 9 and the electrode contact plate 10 are in contact, and the power can be turned on when the electrode contact piece 9 and the electrode contact plate 10 are disconnected.
