Description

Technical Field

[0001] This utility model relates to the field of metal detection equipment technology, specifically to a convenient retractable anti-high voltage interference metal detector. Background Technology

[0002] Metal detectors are widely used in security inspections, mineral exploration, archaeological excavations, and other fields. In environments with strong electromagnetic interference, such as high-voltage transmission lines and substations, traditional metal detectors are easily affected, leading to signal distortion, increased false alarm rates, and severely impacting accuracy and reliability. This has led to the development of metal detectors with high-voltage interference resistance. For example, Chinese utility model patent CN215986542U discloses a portable detector and a high-voltage resistant detector. The detector includes a main frame and a detection coil mounted on it. The main frame includes a telescopic frame and two horizontal connecting seats fixed at its front and rear ends. Each horizontal connecting seat has two pull rods mounted on its left and right sides, symmetrically arranged. Each pull rod has a wire clip at its end, and the detection coil is secured within one of the four wire clips. The four pull rods, through the four wire clips, extend the detection coil. This utility model effectively solves the problem of high-voltage line interference, making detection less susceptible to interference.

[0003] However, the metal detectors in the existing technologies mentioned above are still quite bulky when folded and stored, and the efficiency of switching between usage states is low, which makes it inconvenient to store and use the metal detectors. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a convenient retractable anti-high voltage interference metal detector. By setting an anti-high voltage interference arm and an anti-high voltage interference coil structure on the upright support, the detection accuracy and reliability under high voltage environment are effectively improved. The detection arm can swing and retract through the hinge seat. The anti-high voltage interference arm and the locking sleeve on the bearing sleeve can be detachably connected, making the switching of the metal detector's working state more flexible and convenient. The size is smaller after folding, and the metal detector is quicker to retract and deploy.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a convenient retractable anti-high voltage interference metal detector, including a support, a detection arm with one end disposed at one end of the support, and an anti-high voltage interference arm arrayed on the side of the support. The other end of the support is provided with a detector main unit assembly. A detection coil is connected between the other ends of the detection arm and an anti-high voltage interference coil is connected between the other ends of the anti-high voltage interference arm. The ends of the detection coil and the anti-high voltage interference coil are respectively connected to the detector main unit assembly.

[0006] The ends of several of the aforementioned detection arms are swayably disposed at one end of the upright support. A bearing sleeve is movably disposed on the side of the upright support. A locking sleeve for locking the anti-high voltage interference arm is disposed on the side of the bearing sleeve. The anti-high voltage interference arm is detachably connected to the locking sleeve. The axis of the anti-high voltage interference arm and the detection arm are set at an acute angle. A locking structure for locking the rotation angle is disposed on the bearing sleeve.

[0007] One end of the upright is provided with a hinge seat, and several of the probe arms are hinged on the hinge seat. The locking structure includes a guide rod and a locking rod respectively provided on one side of the bearing sleeve. The side of the hinge seat is respectively provided with a limit groove, a positioning groove one and a positioning groove two. The guide rod is swung in the limit groove, and the locking rod is switchably provided in the positioning groove one and the positioning groove two.

[0008] A compression spring is fitted on the outer side of the upright support, one end of which abuts against the bearing sleeve. A stop is provided on the side of the upright support, and the other end of the compression spring abuts against the stop.

[0009] The detection arm includes a sleeve and a support rod with one end slidably inserted inside the sleeve. The end of the sleeve is hinged to the hinge seat, and the other end of the support rod is provided with a buckle for fixing the detection coil.

[0010] The anti-high voltage interference support arm includes a sleeve and a support rod 2 with one end slidably inserted inside the sleeve. The opening of the locking sleeve is obliquely upward on the bearing sleeve. The end of the sleeve is detachably connected to the locking sleeve. The other end of the support rod 2 is provided with a buckle 2 for fixing the anti-high voltage interference coil.

[0011] The side of the support is provided with a snap-fit ​​plate for fixing the detection arm, and the snap-fit ​​plate is provided with a snap-fit ​​groove that can be detachably snapped into the detection arm.

[0012] The side of the detection arm is provided with a locking block for fixing the anti-high voltage interference arm, and the anti-high voltage interference arm is detachably connected to the locking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting up an anti-high voltage interference support arm and an anti-high voltage interference coil structure on the support, the detection accuracy and reliability under high voltage environment are effectively improved. The detection support arm can swing and retract through the hinge seat. The anti-high voltage interference support arm and the locking sleeve on the bearing sleeve can be separated and connected, making the switching of the working state of the metal detector more flexible and convenient. The folded volume is smaller and the metal detector can be retracted and retracted more quickly.

[0015] (2) A locking structure consisting of a guide rod, a locking rod, and a compression spring is provided to lock the angle of the locking sleeve and the anti-high voltage interference support arm on it, thereby allowing the locking sleeve to avoid the folded detection support arm, further reducing the volume of the metal detector after folding, making the metal detector easier and faster to put away and put away, and more stable and reliable.

[0016] (3) The detection arm includes a sleeve one and a support rod one that slides through the sleeve one at one end. The anti-high voltage interference arm includes a sleeve two and a support rod two that slides through the sleeve two at one end. The size of the detection coil and the anti-interference coil can be flexibly adjusted, which enhances the applicability of the equipment in different scenarios. Attached Figure Description

[0024] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0025] See Figures 1-6 A convenient retractable anti-high voltage interference metal detector includes a support 1, a detection arm 4 with one end set at one end of the support 1, and anti-high voltage interference arms 8 with one end arrayed on the side of the support 1. The other end of the support 1 is provided with a detector main unit assembly 2. The other ends of the detection arm 4 are connected to a detection coil 5, and the other ends of the anti-high voltage interference arms 8 are connected to an anti-high voltage interference coil 9. The ends of the detection coil 5 and the anti-high voltage interference coil 9 are respectively connected to the detector main unit assembly 2.

[0026] Several probe arms 4 are swayed at one end of the support 1. The support 1 is movably provided with a bearing sleeve 6. The bearing sleeve 6 is provided with a locking sleeve 7 for locking the anti-high voltage interference support arm 8. The anti-high voltage interference support arm 8 and the locking sleeve 7 are detachably connected. The axis of the anti-high voltage interference support arm 8 and the probe arm 4 are set at an acute angle. The bearing sleeve 6 is provided with a locking structure for locking the rotation angle.

[0027] One end of the support 1 is provided with a hinge seat 3, and several probe arms 4 are hinged on the hinge seat 3. The locking structure includes a guide rod 61 and a locking rod 62 respectively provided on one side of the bearing sleeve 6. The side of the hinge seat 3 is respectively provided with a limit groove 31, a positioning groove 1 32 and a positioning groove 2 33. The guide rod 61 is swung in the limit groove 31, and the locking rod 62 is switchably provided in the positioning groove 1 32 and the positioning groove 2 33.

[0028] A compression spring 10 is fitted on the outer side of the support 1. One end of the compression spring 10 abuts against the bearing sleeve 6. A stop 11 is provided on the side of the support 1. The other end of the compression spring 10 abuts against the stop 11.

[0029] The detection arm 4 includes a sleeve 41 and a support rod 42 with one end slidably inserted inside the sleeve 41. The end of the sleeve 41 is hinged to the hinge seat 3, and the other end of the support rod 42 is provided with a buckle 43 for fixing the detection coil 5.

[0030] The anti-high voltage interference support arm 8 includes a sleeve 81 and a support rod 82 with one end slidably inserted inside the sleeve 81. The opening of the locking sleeve 7 is obliquely upward on the bearing sleeve 6. The end of the sleeve 81 is detachably connected to the locking sleeve 7. The other end of the support rod 82 is provided with a buckle 83 for fixing the anti-high voltage interference coil 9. The locking sleeve 7 is implemented using existing technology and will not be described in detail here.

[0031] It is understandable that by tilting the bearing sleeve 6, the anti-high voltage interference support arm 8 and the detection support arm 4 form an acute angle, and a height difference is generated between the ends of the anti-high voltage interference support arm 8 and the detection support arm 4, so that the anti-high voltage interference coil 9 is positioned above the detection coil 5, thereby producing the effect of anti-high voltage interference.

[0032] The side of the support 1 is provided with a snap-fit ​​plate 12 for fixing the detection arm 4. The snap-fit ​​plate 12 is provided with a snap-fit ​​groove that can be snapped into the detection arm 4.

[0033] The side of the detection arm 4 is provided with a snap-fit ​​block 13 for fixing the anti-high voltage interference arm 8. The anti-high voltage interference arm 8 and the snap-fit ​​block 13 are detachably connected.

[0034] The detector main unit 2 is implemented using existing technology. Specifically, the detector main unit 2 includes a connecting block 23 at the end of the support 1, a main unit 24 on the connecting block 23, and a main unit 25 inside the support 1. The main unit 24 is a metal detector main unit with high voltage resistance (equipped with a high voltage interference processor), and the main unit 25 is a general detector processor. The connecting block 23 is equipped with a knob group for controlling the detector unit 2. The side of the support 1 is equipped with an interface 21 and an interface 22. The interface 21 is electrically connected to the main unit 24 and the high voltage interference coil 9, respectively, and the interface 22 is electrically connected to the main unit 25 and the detection coil 5, respectively. The side of the connecting block 23 is equipped with a battery for supplying power to the main unit 24 and the main unit 25. In order to reduce the size of the metal detector, the main unit 25 is located inside the support 1. The connection of the main unit 24, the main unit 25 and other components in the detector main unit 2 is implemented using existing technology, which will not be described in detail here. The connecting block 23 is equipped with a handle for hand operation.

[0035] The specific working process of this utility model:

[0036] Instructions for use: First, remove the detection arm 4 from the snap-fit ​​slot of the snap-fit ​​plate 12, swing it to the horizontal working position, and pull out the support rod 42 to the appropriate length. Fix the detection coil 5 and connect the end of the detection coil 5 to the interface 22. Then, remove the anti-high voltage interference arm 8 from the snap-fit ​​block 13 and install it on the locking sleeve 7. Overcome the elastic force of the compression spring 10 and slide the bearing sleeve 6 upward to disengage the locking rod 62 from the positioning groove 33. Then rotate the bearing sleeve 6, guided by the guide rod 61 in the limiting groove 31, and rotate it to the working position. Under the action of the spring force, the locking rod 62 snaps into the positioning groove 32 and locks. Finally, pull out the support rod 82 to the appropriate length, fix the anti-high voltage interference coil 9, and finally connect the end of the anti-high voltage interference coil 9 to the interface 21. Turn on the main unit 2 of the detector and walk by holding the handle to perform metal detection. When the anti-high voltage interference function is not needed, remove the anti-high voltage interference arm 8, and you can perform detection by just the detection coil 5. The metal detector is more convenient to use and easier to put away and put away.

[0037] Folding and Carrying: The process is the reverse of the above. After removing the detection coil 5 and the anti-high voltage interference coil 9, remove the anti-high voltage interference support arm 8 from the locking sleeve 7. Overcome the elastic force of the compression spring 10 and slide the bearing sleeve 6 upward to separate the locking rod 62 from the positioning groove 32. Then rotate the bearing sleeve 6, and under the action of the compression spring 10, insert the locking rod 62 into the positioning groove 33. Then retract and fix each anti-high voltage interference support arm 8 and the detection support arm 4. Rotate the detection support arm 4 and lock it into the locking groove of the locking plate 12. Then lock the anti-high voltage interference support arm 8 onto the locking block 13 of the detection support arm 4. At this time, the anti-high voltage interference support arm 8 is close to the detection support arm 4, completing the folding and storage.

[0038] By incorporating an anti-high voltage interference arm 8 and an anti-high voltage interference coil 9 on the support 1, the detection accuracy and reliability under high voltage conditions are effectively improved. The detection arm 4 is retracted and extended via a hinged seat 3. The anti-high voltage interference arm 8 and the locking sleeve 7 on the bearing sleeve 6 can be detached and connected, making the switching of the metal detector's working state more flexible and convenient. Specifically, when working in the normal working state, the anti-high voltage interference arm 8 can be removed, making the metal detector lighter to use. When working in the anti-high voltage interference working state, the anti-high voltage interference support rod and the anti-high voltage interference coil 9 are installed, making the metal detector more compact when folded and the metal detector quicker to retract and extend.

[0039] A locking structure consisting of a guide rod 61, a locking rod 62, and a compression spring 10 is provided to lock the angle of the locking sleeve 7 and the anti-high voltage interference support arm 8 on it, thereby allowing the locking sleeve 7 to avoid the folded detection support arm 4, further reducing the volume of the metal detector after folding, making the metal detector easier and faster to put on and take off, and more stable and reliable.

[0040] The detection arm 4 includes a sleeve 41 and a support rod 42 that slides through the sleeve 41 at one end. The anti-high voltage interference arm 8 includes a sleeve 81 and a support rod 82 that slides through the sleeve 81 at one end. The size of the detection coil 5 and the anti-high voltage interference coil 9 can be flexibly adjusted, which enhances the applicability of the equipment in different scenarios.

[0041] 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.
