Description

Technical Field

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

[0002] Metal detectors, as an important detection device, are widely used in security inspections, mineral exploration, and industrial testing. They are also called metal detectors. Traditional outdoor metal detectors usually consist of a detector main unit, a rigid bracket, and a detection coil. The end of the detection coil is electrically connected to the main unit. The detection coil is wound around the detection plate at the end of the bracket to form the coil detection area. In order to increase the coverage area of ​​the detection coil and improve detection efficiency, metal detectors often need to increase the unfolded area of ​​the bracket. However, when the unfolded area of ​​the bracket is increased, it often results in a larger overall size of the metal detector, leading to poor portability.

[0003] Existing metal detectors are bulky when stored, making them inconvenient to carry and use. This solution addresses these technical problems. Utility Model Content

The telescopic bottom support includes a telescopic horizontal support hinged to a hinge seat and a telescopic rod, the other end of which is hinged between the two telescopic horizontal supports. The telescopic top support and the telescopic horizontal support are connected by a hinge seat, making the folding detector bracket more compact and portable when folded, and convenient and quick to unfold. Furthermore, the coil detection area formed by the detection frame after unfolding is larger, making the metal detector more convenient and quick to detect metal.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a portable metal detector, including a detector host and a folding detector bracket, the folding detector bracket including a telescopic top support and a detection frame connected to both ends of the telescopic top support, a detection coil being detachably disposed on the detection frame, and the end of the detection coil being electrically connected to the detector host;

One end of the hinge block 2 is fixedly connected to the telescopic rod 2, and the other end of the hinge block 2 is hinged to the telescopic cross brace. A locking component for locking the angle of the telescopic cross brace is provided on the side of the hinge block 2.

[0008] The locking assembly includes two connecting seats disposed on the side of the second hinge block, a bolt passing through the two connecting seats, a connecting plate rotatably mounted on the bolt at one end, and a locking rod disposed at the other end of the connecting plate. A through hole is provided on the side of the second hinge block, and a locking hole is provided on the side of the telescopic cross brace. The locking rod passes through the through hole and is detachably connected to the locking hole. A hand-tightening nut for clamping the connecting plate is provided on the outside of the bolt.

The inner side of the second hinge block is provided with a limiting platform for clamping the telescopic cross brace.

[0010] The telescopic cross brace and the telescopic rod 2 are respectively provided with coil fixing blocks. The coil fixing blocks are provided with limiting grooves for accommodating the detection coils. The detection coils can be detachably locked in the limiting grooves.

[0011] The hinge seat includes a connecting sleeve fixedly connected to the telescopic upright and positioning grooves respectively disposed on the side of the hinge seat, and the telescopic cross brace is hinged in the positioning groove.

[0012] Both telescopic rod one and telescopic rod two are three-section pull-out rod structures, and both telescopic rod one and telescopic rod two are provided with two locking rings on their outer sides for locking the length.

[0028] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0029] See Figures 1-8 A portable metal detector includes a detector host 1 and a foldable detector bracket. The foldable detector bracket includes a telescopic top support 2 and a detector frame 3 connected to both ends of the telescopic top support 2. A detector coil 4 is detachably disposed on the detector frame 3, and the end of the detector coil 4 is electrically connected to the detector host 1.

[0030] The telescopic top support 2 includes a telescopic rod 21 and two telescopic upright supports 22, one end of which is hinged to both ends of the telescopic rod 21. The detector host 1 is mounted on the telescopic rod 21. The detector frame 3 includes a hinge seat 31 connected to the other end of the telescopic upright support 22 and a telescopic bottom support 32 hinged between the two hinge seats 31. The telescopic bottom support 32 includes a telescopic cross support 321 hinged to the hinge seat 31 and a telescopic rod 322 hinged between the two telescopic cross supports 321.

[0031] A hinge block 33 is provided between the telescopic cross brace 321 and the telescopic rod 322. One end of the hinge block 33 is fixedly connected to the telescopic rod 322, and the other end of the hinge block 33 is hinged to the telescopic cross brace 321. A locking component 331 for locking the angle of the telescopic cross brace 321 is provided on the side of the hinge block 33.

[0032] The locking assembly 331 includes two connecting seats 3311 disposed on the side of the hinge block 33, a bolt 3312 disposed between the two connecting seats 3311, a connecting plate 3313 rotatably disposed on the bolt (3312) at one end, and a locking rod 3314 disposed on the other end of the connecting plate 3313. A through hole is disposed on the side of the hinge block 33, and a locking hole 3211 is disposed on the side of the telescopic cross brace 321. The locking rod 3314 passes through the through hole and is detachably connected to the locking hole 3211. A hand-tightening nut 3315 for clamping the connecting plate 3313 is disposed on the outside of the bolt 3312.

[0033] Specifically, the connecting seat 3311 is made of a material with a certain degree of elastic deformation, such as nylon, ABS engineering plastic, PC material, and polypropylene PP, so that when the hand-tightening nut 3315 is turned, the connecting seat 3311 can press and fasten the connecting plate 3313. The two sides of the connecting plate 3313 in contact with the connecting seat 3311 and the inner sides of the two connecting seats 3311 are provided with anti-slip texture to improve the friction between the connecting seat 3311 and the connecting plate 3313. This makes the fastening effect of the connecting seat 3311 on the connecting plate 3313 better when it presses the connecting plate 3313, so that the locking rod 3314 is not easy to come out of the locking hole 3211.

[0034] The end of the hinge block 33 is provided with an opening groove for accommodating the telescopic cross brace 321. The edge of the opening groove is provided with a shrinkage limiting part 333. The inner side of the hinge block 33 is provided with a limiting platform 332 for clamping the telescopic cross brace 321. Both the shrinkage limiting part 333 and the limiting platform 332 are made of plastic material that allows elastic deformation. The telescopic cross brace 321 is constrained and limited by the compression of the shrinkage limiting part 333 and the limiting platform 332.

[0035] A coil fixing block 34 is provided on the telescopic cross brace 321 and the second telescopic rod 322 respectively. The coil fixing block 34 is provided with a limiting groove 341 for accommodating the detection coil 4. The detection coil 4 can be detachably locked in the limiting groove 341. Furthermore, the coil fixing block 34 is rotatably set on the side of the telescopic cross brace 321 and the second telescopic rod 322 so that when folded and stored, the metal detector can be made more compact after folding by rotating the coil fixing block 34, while the detection coil 4 is fixed by the limiting groove 341.

[0036] The hinge seat 31 includes a connecting sleeve 311 fixedly connected to the telescopic support 22 and positioning grooves 312 respectively disposed on the side of the hinge seat 31. The telescopic cross brace 321 is hingedly disposed in the positioning groove 312.

[0037] Both telescopic rod 1 (21) and telescopic rod 2 (322) are three-section pull-out rod structures. Both telescopic rod 1 (21) and telescopic rod 2 (322) have two locking rings on their outer sides for locking the length. The locking rings are implemented using existing technology and will not be described in detail here.

[0038] Both the telescopic cross brace 321 and the telescopic vertical brace 22 are two-section pull-out rod structures, and both the telescopic cross brace 321 and the telescopic vertical brace 22 are equipped with locking rings for locking the length.

[0039] It is understandable that both the three-section pull-out rod structure and the two-section pull-out structure are implemented using existing technology, and the rod body is pulled out and extended through a sleeve. Their specific structure is the same as the pull-out structure of the tripod in the existing technology, and will not be described in detail here.

[0040] A hinge block 23 is provided between the telescopic rod 21 and the telescopic support 22. The end of the telescopic rod 21 is fixedly mounted on the hinge block 23, and the telescopic support 22 is hinged on the hinge block 23. A limiting platform 332 for clamping the telescopic support 22 is also provided on the inner side of the hinge block 23.

[0041] The specific working process of this utility model:

[0042] See Figure 3 This is a schematic diagram of the folded configuration of the portable metal detector of this solution. In use, rotate the four telescopic cross braces 321 along the hinge block 33. When the telescopic cross braces 321 rotate to a 90-degree angle with the telescopic rod 322, manually rotate the connecting plate 3313. The locking rod 3314 on the connecting plate 3313 passes through the through hole on the hinge block 33 and inserts into the locking hole 3211 of the telescopic cross brace 321. At this point, the locking rod 3314 locks the telescopic cross brace 321. Tighten the hand-tightening nut 3315. The hand-tightening nut 3315, through the connecting seat 3311, firmly presses the connecting plate 3313, preventing the locking rod 3314 from disengaging from the locking hole 3211. After locking all the locking components 331 on the four hinge blocks 33, the portable metal detector's configuration is shown in the diagram. Figure 2 Then, loosen the locking rings on the telescopic cross brace 321, telescopic vertical brace 22, telescopic rod one 21 and telescopic rod two 322 respectively, so that the telescopic cross brace 321 and telescopic vertical brace 22 extend out of the set length at the same time, and the telescopic rod one 21 and telescopic rod two 322 extend and retract to the set length at the same time, and then tighten all the locking rings.

[0043] Rotate the four telescopic cross braces 321 along the hinge seat 31. Under the limiting action of the bottom of the positioning groove 312, the ends of the telescopic upright braces 22 are perpendicular to the telescopic cross braces 321 and the telescopic upright braces 22, so that the cross bar and the telescopic rod 22 form a rectangular telescopic base support 32. At this time, the side of the detection coil 4 is sequentially snapped into the limiting groove 341 on the coil fixing block 34. The detection coil 4 forms a coil detection area that matches the shape of the telescopic base support 32. Then, connect the end of the detection coil 4 to the detector host 1. Then, put both legs into the telescopic base support 32, hold the telescopic rod 21 and start the detector host 1. You can then perform metal detection operations while walking.

[0044] After use, first turn off the detector host 1, unplug the detector coil 4 from the detector host 1, remove the limiting groove 341 on the detector coil 4 and the coil fixing block 34, and fold the portable metal detector. The folding process of the metal detector is the reverse of the unfolding process, and will not be described in detail again.

[0045] The telescopic top support 2 includes a telescopic rod 21 and two telescopic upright supports 22, one end of which is hinged to both ends of the telescopic rod 21. The telescopic bottom support 32 includes a telescopic horizontal support 321 that is hinged to the hinge seat 31 and a telescopic rod 322 that is hinged to both ends between the two telescopic horizontal supports 321. The telescopic top support 2 and the telescopic horizontal support 321 are connected through the hinge seat 31, which makes the folding detection bracket more compact and portable when folded, and convenient and quick when unfolded. After unfolding, the coil detection area formed by the detection frame 3 is larger, which makes the metal detector more convenient and quick to detect metal.

[0046] By setting the locking component 331 on the hinge block 33, the connecting seat 3311 fixes the connecting plate 3313 by turning the hand nut 3315, thereby allowing the locking rod 3314 to be inserted into the locking hole 3211 to lock the telescopic rod 322 at an angle. The locking rod 3314 is firmly and reliably fixed, and folding is convenient and quick.

[0047] The end of the hinge block 33 is provided with an opening groove for accommodating the telescopic cross brace 321. The edge of the opening groove is provided with a retraction limiting part 333. The inner side of the hinge block 33 is provided with a limiting platform 332 for clamping the telescopic cross brace 321. The limiting platform 332 limits the telescopic cross brace 321 in the folded state, and the retraction limiting part 333 limits the telescopic cross brace 321 in the unfolded state, thereby making the angle of the telescopic cross brace 321 more stable, reliable, convenient and quick to fix when unfolding and folding.

[0048] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
