Description

Technical Field

[0001] The utility model relates to the field of microwaves, and specifically to a self-inductive anti-static wristband. Background Art

[0002] The existing anti-static alarm needs to turn on the power switch to have the alarm and anti-static functions. If the operator forgets to turn on the switch, the anti-static alarm will have no effect at all.

[0003] In actual use, the phenomenon of forgetting to turn on the switch often occurs, which also leads to potential safety hazards of the product. Summary of the Utility Model

[0004] Purpose of the utility model: To provide a self-inductive anti-static wristband to solve the above problems existing in the prior art.

[0005] Technical solution: A self-inductive anti-static wristband includes:

[0006] A wristband and an alarm end adapted to the wristband;

[0007] The alarm end includes:

[0008] A cavity with an anti-static alarm built therein, and a wristband interface is opened at one end;

[0009] A trigger circuit is arranged in the cavity, including a power supply, a voltage regulator connected to the power supply, a relay connected to the voltage regulator, and a U-shaped opposed photoelectric sensor connected to the relay and arranged at the wristband interface;

[0010] The relay is connected to the anti-static alarm;

[0011] The U-shaped opposed photoelectric sensor is connected to the voltage regulator;

[0012] When the U-shaped opposed photoelectric sensor is blocked, the relay is controlled to supply power to the anti-static alarm.

[0013] In the utility model, a trigger circuit is designed in the cavity, and a U-shaped opposed photoelectric sensor is designed at the wristband interface. When the wristband plug is inserted into the cavity through the wristband interface, the wristband plug blocks the light between the transmitting end and the receiving end. When the light is blocked, the U-shaped opposed photoelectric sensor controls the relay to turn on the switch and supply power to the anti-static alarm. At this time, the anti-static alarm starts to work.

[0014] Through the design of the above scheme, the traditional way of turning on the switch of the anti-static alarm is cancelled. When the wristband is inserted into the wristband interface, the anti-static alarm can work.

[0015] In a further embodiment, a wristband plug is provided at the end of the wristband, and the wristband plug is adapted to the wristband interface.

[0016] In a further embodiment, the end of the wristband plug has an L-shaped blocking bump, and a clamping step adapted to the L-shaped blocking bump is disposed in the cavity.

[0017] With the design of the L-shaped blocking bump, after the wristband plug is inserted, it is slightly rotated, so that the L-shaped blocking bump of the wristband plug will catch the clamping step and is not easily disengaged, and it can be aligned when pulled out.

[0018] In a further embodiment, the U-shaped opposed photoelectric sensor includes a transmitting end and a receiving end respectively disposed at the wristband interface and oppositely disposed.

[0019] In a further embodiment, a telescopic rod is further disposed in the cavity, and a resisting block is disposed at the end of the telescopic rod;

[0020] A spring connecting the resisting block and the inner wall of the cavity is sleeved on the telescopic rod.

[0021] Through the design of the telescopic rod, the spring and the resisting block, the L-shaped blocking bump is subjected to the pressure of the spring, so that it is always engaged with the clamping step, avoiding the phenomenon of falling off;

[0022] When pulling out, the wristband plug presses against the resisting block and moves towards the spring end. After moving to a predetermined distance, rotate the wristband plug, align the position, and then pull out the wristband plug.

[0023] Beneficial effects: The present utility model discloses a self-inductive anti-static wristband. The present utility model designs a trigger circuit in the cavity and a U-shaped opposed photoelectric sensor at the wristband interface. When the wristband plug is inserted into the cavity from the wristband interface, the wristband plug blocks the light between the transmitting end and the receiving end. When the light is blocked, the U-shaped opposed photoelectric sensor controls the relay to turn on the switch to supply power to the anti-static alarm, and at this time the anti-static alarm starts to work.

[0030] This application relates to a self - inductive anti - static wristband, which will be explained in detail through specific implementation modes below.

[0031] A self - inductive anti - static wristband includes:

[0032] A wristband 1 and an alarm terminal adapted to the wristband 1;

[0033] The alarm terminal includes:

[0034] A cavity 2, with an anti - static alarm installed inside, and a wristband interface 21 opened at one end;

[0035] A trigger circuit, arranged inside the cavity 2, includes a power supply, a voltage regulator connected to the power supply, a relay connected to the voltage regulator, and a U - shaped opposed photoelectric sensor connected to the relay and arranged at the wristband interface 21;

[0036] The relay is connected to the anti - static alarm;

[0037] The U - shaped opposed photoelectric sensor is connected to the voltage regulator;

[0038] In this utility model, a trigger circuit is designed inside the cavity 2, and a U - shaped opposed photoelectric sensor is designed at the wristband interface 21. When the wristband plug 12 is inserted into the cavity 2 through the wristband interface 21, the wristband plug 12 blocks the light between the transmitting end and the receiving end. When the light is blocked, the U - shaped opposed photoelectric sensor controls the relay to turn on the switch and supply power to the anti - static alarm. At this time, the anti - static alarm starts to work.

[0039] Through the design of the above - mentioned scheme, the traditional way of turning on the switch of the anti - static alarm is cancelled. When the wristband is inserted into the wristband interface 21, the anti - static alarm can work.

[0040] The end of the wristband 1 is provided with a wristband plug 12, and the wristband plug 12 is adapted to the wristband interface 21.

[0041] The end of the wristband plug 12 has an L - shaped blocking convex block 13, and the cavity 2 is internally provided with a clamping step 25 adapted to the L - shaped blocking convex block 13.

[0042] With the design of the L - shaped blocking convex block 13, after the wristband plug 12 is inserted, turn it slightly. In this way, the L - shaped blocking convex block 13 of the wristband plug 12 will be stuck to the clamping step 25, and it is not easy to come out. Just align it when pulling it out.

[0043] The U - shaped opposed photoelectric sensor includes a transmitting end and a receiving end which are respectively arranged at the wristband interface 21 and are oppositely arranged.

[0044] A telescopic rod 22 is further provided in the cavity 2, and a blocking block 24 is provided at the end of the telescopic rod 22;

[0045] A spring 23 is sleeved on the telescopic rod 22 and is connected to the blocking block 24 and the inner wall of the cavity 2.

[0046] Through the design of the telescopic rod 22, the spring 23 and the blocking block 24, the L-shaped blocking convex block 13 is subjected to the pressure of the spring 23, so that it is always engaged with the clamping step 25, avoiding the phenomenon of falling off;

[0047] When pulling out, the wristband plug 12 presses against the blocking block 24 and moves towards the end close to the spring 23. After moving to a predetermined distance, rotate the wristband plug 12, align the position, and then pull out the wristband plug 12.

[0048] Principle of operation description: When the wristband plug 12 is inserted into the cavity 2 from the wristband interface 21, the wristband plug 12 blocks the light between the transmitting end and the receiving end. When the light is blocked, the U-shaped opposed photoelectric sensor controls the relay to turn on the switch, supplying power to the anti-static alarm, and at this time the anti-static alarm starts to work.
