Description

Technical Field

[0001] The utility model relates to the technical field of metal detectors, in particular to an adjustable metal detector. Background Art

[0002] A metal detector is a high-performance metal detector designed specifically for security. There are three main types: electromagnetic induction, X-ray detection, and microwave detection. It is an electronic instrument used to detect metal. The working principle of a metal detector is mainly based on electromagnetic induction, using an induction loop for detection. When an electromagnetic field encounters a metal object, the metal object will generate eddy currents (currents generated by the conductivity of the metal). These eddy currents will generate their own electromagnetic fields inside the metal object. This process is called induction.

[0003] A metal detector is disclosed in the patent with publication number CN221261252U, which includes a connecting rod, the outer surface of which is fixedly connected to a mounting plate, the outer surface of which is fixedly connected to a panel, the upper surface of which is fixedly connected to a grip rod, the outer surface of which is slidably connected to a connecting sleeve, and the outer surface of which is fixedly connected to a wrist guard.

[0004] In the above technology, the overall length of the adjusting rod and the connecting rod can be adjusted by sliding the adjusting rod on the inner side of the connecting rod. When the user's hand is separated from the grip rod due to error, the metal detector will fall directly to the ground. The fall may damage the circuit inside the induction loop, resulting in a decrease in detection accuracy. The wrist guard provided in the above technology cannot clamp the user's wrist, so innovation is made in this technology. Summary of the Invention

[0025] Working principle: The metal detector is a high-performance metal detector designed for security; there are three main categories: electromagnetic induction type, X-ray detection type and microwave detection type. It is an electronic instrument used to detect metal. The working principle of the metal detector is mainly based on electromagnetic induction, using the induction ring 3 for detection. When the electromagnetic field encounters a metal object, the metal object will generate eddy currents. The current generated by the conductivity of the metal, these eddy currents will generate its own electromagnetic field inside the metal object. This process is called induction. The processed signal will be compared with the preset reference signal to determine whether there is a metal object. If an abnormal signal is detected, the detector will emit sound, vibration and visual prompts to warn the user. The fitting block 11 can move left and right at one end of the fitting rod 10, and under the connection of the L-shaped plate 12, it can drive the first magnet ring 13 to move left and right, so that the distance between the first magnet ring 13 and the second magnet ring 15 can be adjusted. The position of the first magnet ring 13 can be adjusted according to the width of the user's wrist. The first magnet ring 13 and the second magnet ring 15 is a neodymium magnet, which can provide greater adsorption force. The two are magnetically connected. After the first magnet ring 13 is close to the second magnet ring 15, the two are adsorbed on each other. The first magnet ring 13 and the second magnet ring 15 can clamp the user's wrist, enhancing the stability of the user in holding the handle 4. The thin pad 16 is made of sponge and is relatively soft. It improves the user's feeling of use by contacting the wrist skin and avoids the metal detector from colliding with the ground and being damaged. The screw 7 is embedded in the interior of the positioning sleeve 6 and the limit nut 8 is set. At one end of the screw rod 7, the two are threadedly sleeved, so that the positioning sleeve 6 and the screw rod 7 can be limited and fixed. By moving the fitting block 11, the position of the first magnet ring 13 can be adjusted. After the first magnet ring 13 reaches the appropriate position, one end of the torsion rod 17 is embedded into the concave hole 18 and the inside of the embedding hole. The three are threadedly connected, so the cross plate 9 and the fitting block 11 can be installed. By rotating the limit nut 8 in the opposite direction, the screw rod 7 and the positioning sleeve 6 can be separated from each other, and the screw 7 can be separated from the grip rod 4 for easy storage.
