Description

Technical Field

[0001] This utility model relates to the field of metal detector technology, specifically to a lightweight metal detector. Background Technology

[0002] Metal detectors, as an important detection device, are widely used in security inspections, mineral exploration, and industrial testing. A metal detector typically consists of a detector main unit, a support, and a detection coil. One end of the detection coil is connected to the main unit, and the other end is connected to the end of the support, forming the coil detection area. The support arm can be extended or retracted to adjust the size of the detection area.

[0003] Because the detection coil forms a large area when the arm of the metal detector is extended, the metal detector often becomes unstable due to uneven center of gravity when operated by hand. This is especially true when the detection area needs to be frequently adjusted or when used in a confined space. The metal detector lacks flexibility, and prolonged hand operation can easily lead to user fatigue, affecting detection accuracy and user experience. This solution addresses the above-mentioned technical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lightweight metal detector. By setting a counterweight component on the support arm, and filling the counterweight box of the counterweight component with an appropriate weight of counterweight medium, the weight of the connecting cable on the other arm is balanced, making the metal detector more stable and reliable in use, reducing fatigue when operating the metal detector by hand, and the setting of the hinge block makes the metal detector easier and more reliable to unfold and use, and more compact and portable when folded, making it more lightweight and flexible in use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lightweight metal detector, comprising a detector body for detecting metal, the detector body comprising a riser, a detector host connected to one end of the riser, and a plurality of arms, one end of which is respectively hinged to the other end of the riser, a detection coil connected between the other ends of the plurality of arms, a connecting cable connecting the detection coil and the detector host, the plurality of arms being arranged in a symmetrical array at the other end of the riser, the connecting cable being laid along one of the arms, and a counterweight assembly being provided on the symmetrical arms of the connecting cable at the end of the riser, the counterweight assembly being used to balance the weight of the connecting cable.

[0006] The counterweight assembly includes a short rod connected to the support arm, a box body connected to the short rod on one side, and a buckle disposed on the other side of the box body for fixing the detection coil. The detection coil passes through the buckle. The top side of the box body is provided with a lid for sealing the counterweight medium.

[0007] A handle is provided at one end of the riser, and the detector host is located at one end of the handle. The other end of the handle is connected to the riser. A wire is inserted through the riser. One end of the wire passes through the handle and is connected to the detector host. The other end of the wire is connected to the connecting cable.

[0008] The other end of the riser is provided with a hinge block, and the side of the hinge block is provided with an array of hinge seats corresponding to the support arm. One end of the support arm is provided with a connecting block, and the connecting block is hinged to the hinge seat. The side of the hinge block is provided with a retaining groove, and one end of the connecting block is provided with a retaining block. The retaining block is in separable contact with the bottom of the retaining groove.

[0009] The buckle has a groove on its side for accommodating the detection coil. On the side of the groove facing the opening, there is a plastic baffle for locking the detection coil. One end of the plastic baffle is fixedly connected to one side of the groove, and the other end of the plastic baffle is detachably abutted against the other side of the groove.

[0010] Each end of the support arm is equipped with a buckle, and the detection coil passes through the buckle in sequence.

[0011] The detection coil is a spiral cable.

[0012] It also includes a monitoring headset that is wirelessly connected to the detector host.

[0013] The riser is provided with a plug on its side, the wire is connected to the plug, and the end of the connecting cable is provided with a plug that is electrically connected to the plug.

[0014] The outer side of the handle is provided with a grip groove that fits the fingers.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By setting a counterweight assembly on the support arm, the counterweight box of the counterweight assembly is filled with an appropriate weight of counterweight medium, which balances the weight of the connecting cable on the other arm, making the use of the metal detector more stable and reliable, reducing fatigue when operating the metal detector by hand, and making it more lightweight and flexible.

[0017] (2) The arm is hinged to the hinge seat of the hinge block through the connecting block, and the arm can be unfolded and fixed and folded by the stop block on the connecting block and the stop groove on the hinge block. The metal detector is more convenient and reliable to unfold and more compact and portable when folded.

[0018] (3) By wirelessly connecting the monitoring earpiece to the detector host, the signal of the detected metal is listened to through the monitoring earpiece, which reduces the weight of the handheld detector, making the handheld metal detector host lighter and more flexible, and improving the efficiency of the metal detector.

[0019] (4) After the metal detection operation is completed, the arm is retracted and folded along the hinge block. At this time, the detection coil is retracted due to the expansion and contraction characteristics of the spiral cable material, thus realizing the storage of the detection coil and completing the folding of the entire metal detector. By setting the detection coil to the material of the spiral cable, the length of the detection coil can be adaptively adjusted after the arm is extended and retracted in order to adapt to the narrow environment. This eliminates the need to change and adjust the detection coil back and forth, and improves the efficiency of the metal detector’s extension and retraction.

[0020] (5) The grip groove on the handle makes the handheld metal detector more secure and reliable, and the attitude adjustment of the metal detector is easier and more convenient. Attached Figure Description

Detailed Implementation

[0030] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0031] See Figures 1-8 A lightweight metal detector includes a detector body for detecting metal. The detector body includes a riser 1, a detector host 2 connected to one end of the riser 1, and several arms 3 with one end hinged to the other end of the riser 1. A detection coil 4 is connected between the other ends of the arms 3. A connecting cable 5 is connected between the detection coil 4 and the detector host 2. The arms 3 are arranged in a symmetrical array at the other end of the riser 1. The connecting cable 5 is laid along one of the arms 3. A counterweight assembly 6 is provided on the symmetrical arms 3 of the connecting cable 5 at the end of the riser 1. The counterweight assembly 6 is used to balance the weight of the connecting cable 5.

[0032] The detector host 2 is equipped with a display screen to observe the parameters of the metal detector. The detector host 2 is existing technology and will not be described in detail here. Several limiting collars are provided on one support arm 3 to fix the connecting cable 5. The connecting cable 5 passes through the limiting collars to ensure that the connecting cable 5 is laid along the support arm 3.

[0033] The counterweight assembly 6 includes a short rod 61 connected to the support arm 3, a box 62 connected to the short rod 61 on one side, and a buckle 63 set on the other side of the box 62 for fixing the detection coil 4. The detection coil 4 is set through the buckle 63. The top side of the box 62 is provided with a box cover 64 for sealing the counterweight medium. The counterweight medium can be sand, soil, or other easily obtainable media.

[0034] A handle 7 is provided at one end of the riser 1, and the detector host 2 is located at one end of the handle 7. The other end of the handle 7 is connected to the riser 1. A wire is installed inside the riser 1. One end of the wire passes through the handle 7 and is connected to the detector host 2. The other end of the wire is connected to the connecting cable 5.

[0035] The other end of the riser 1 is provided with a hinge block 8. The side of the hinge block 8 is provided with a hinge seat 81 corresponding to the support arm 3. One end of the support arm 3 is provided with a connecting block 9. The connecting block 9 is hinged on the hinge seat 81. The side of the hinge block 8 is provided with a retaining groove 82. One end of the connecting block 9 is provided with a retaining block 91. The retaining block 91 and the bottom of the retaining groove 82 are in separable contact.

[0036] The side of the buckle 63 has a groove 631 for accommodating the detection coil 4. On the side of the groove 631 facing the opening, there is a plastic baffle 632 for locking the detection coil 4. One end of the plastic baffle 632 is fixedly connected to one side of the groove 631, and the other end of the plastic baffle 632 is detachably abutted against the other side of the groove 631. Through the tough deformation of the plastic baffle 632, the detection coil 4 can be constrained in the groove 631 of the buckle 63 to prevent the detection coil 4 from falling out. When it is necessary to remove or put away the detection coil 4, press the plastic baffle 632 to remove or put away the detection coil 4.

[0037] Each end of the support arm 3 is equipped with a buckle 63, and the detection coil 4 is sequentially inserted through the buckle 63.

[0038] The detection coil 4 is a spiral cable. By setting the detection coil 4 as a spiral cable, it is easier and faster to retract and store the detection coil 4 when the metal detector is folded and put away.

[0039] It also includes a monitoring headset 10 that is wirelessly connected to the detector host 2. The monitoring headset 10 reduces the weight of the detector body and improves the accuracy of metal detection. The monitoring headset 10 can also be equipped with a button to control the detector host 2, making it convenient to operate the detector host 2.

[0040] The monitoring earpiece 10 can be wirelessly connected to the detector host 2 via Bluetooth or other wireless methods. The wireless connection between the monitoring earpiece 10 and the detector host 2 is achieved using existing technology and will not be described in detail here.

[0041] A plug 11 is provided on the side of the riser 1, and the wire is connected to the plug 11. The end of the connecting cable 5 is provided with a plug 2 51 that is electrically connected to the plug 11, so as to facilitate the connection and disconnection of the connecting cable 5 and the wire.

[0042] The outer side of the handle 7 is provided with a grip groove 71 that fits the fingers. The grip groove 71 makes it easy to hold and operate the handle 7, making the use of the detector more stable and reliable, and making it easier to adjust the posture of the metal detector.

[0043] The specific working process of this utility model:

[0044] In use, extend the riser 1 and support arm 3 to a certain length. Specifically, rotate the support arm 3 so that the connecting block 9 rotates along the hinge seat 81. When the stop block 91 on the connecting block 9 enters the stop groove 82 of the hinge block 8 and contacts the bottom of the stop groove 82, the support arm 3 is fully extended. The detection coil 4 made of spiral cable material is extended under the fixation of the buckle 63. Adjust the length of each support arm 3 to be consistent so that the area of ​​the detection coil 4 meets the requirements. Then hold the handle 7 and release it, allowing the riser 1 to hang freely. If the support arm 3 connected to the connecting cable 5 hangs down and causes the riser 1 to tilt, open the cover 64 on the box 62 and fill it in place inside the box 62. After filling the box with an appropriate counterweight medium, such as sand or soil, and covering it with the cover 64, recheck the tilt of the riser 1 until the support arm 3 of the counterweight component 6 is balanced with the support arm 3 of the connecting cable 5. At this point, the riser 1 is vertical. Since the mass of the other support arms 3 is equal, there is no need to adjust the counterweight, and the center of gravity of the entire metal detector is balanced. By setting the counterweight component 6 on the support arm 3 and filling the counterweight box of the counterweight component 6 with an appropriate weight of counterweight medium, the weight of the connecting cable 5 on the other support arm 3 is balanced, making the use of the metal detector more stable and reliable, reducing fatigue when operating the metal detector by hand, and making it lighter and more flexible to use.

[0045] The support arm 3 is hinged to the hinge seat 81 of the hinge block 8 via the connecting block 9, and the support arm 3 can be unfolded and fixed and folded by the stop block 91 on the connecting block 9 abutting against the stop groove 82 on the hinge block 8. The metal detector is more convenient and reliable to unfold and use, and more compact and portable when folded.

[0046] Start the detector main unit 2, hold the handle 7 and place your fingers in the grip groove 71, put on the monitoring headset 10, and adjust the headset and detector main unit 2 with your other hand. Finally, walk around with the metal detector to detect metal. By wirelessly connecting the monitoring headset 10 to the detector main unit 2 and listening to the metal detection signal through the monitoring headset 10, the weight of the handheld detector is reduced, making the handheld metal detector main unit 2 lighter and more agile, and improving the efficiency of the metal detector.

[0047] After the metal detection operation is completed, the support arm 3 is retracted and folded along the hinge block 8. At this time, the detection coil 4 is retracted due to the expansion and contraction characteristics of the spiral cable material, thus realizing the storage of the detection coil 4 and completing the folding of the entire metal detector. By setting the detection coil 4 to the material of the spiral cable, the efficiency of the metal detector's retraction and extension is improved. Furthermore, in order for operators to adapt to navigating narrow environments, the length of the detection coil 4 can be adaptively adjusted after the support arm 3 is extended or retracted, thus eliminating the need to repeatedly replace and adjust the detection coil 4.

[0048] The grip groove 71 on the handle 7 makes the handheld metal detector more secure and reliable, and makes the attitude adjustment of the metal detector easier and more convenient.

[0049] Traditional metal detectors often lack a balanced cable layout, causing the device's center of gravity to shift. This can increase the operational burden, especially during rapid movement or prolonged use, due to uneven weight distribution. Furthermore, the detection coil 4 is often fixed using simple binding or clip 63 structures, lacking quick disassembly and adjustment capabilities. Additionally, the connection structure between the support arm 3 and the riser 1 is usually quite complex and heavy, making it difficult to achieve folding and storage with a lightweight structure, further limiting the applicable scenarios for the device.

[0050] The lightweight metal detector designed in this scheme achieves weight balance, ease of operation, and improved adaptability while ensuring detection accuracy through optimized structural design. For example, the synergistic design of the symmetrical support arm 3 and the counterweight component 6 can effectively counteract the bias torque of the connecting cable 5; while the hinged support arm 3 and the modular cable fixing structure can balance flexibility and stability to meet diverse detection needs.

[0051] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
