Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection tools, in particular to a handheld mineral electromagnetic detector. BACKGROUND

[0002] The handheld mineral electromagnetic detector, as a convenient detection tool, is widely used in geological exploration, mineral resource exploration and other fields. Its working principle mainly detects the electromagnetic field changes generated by underground minerals through electromagnetic induction technology, helping the operator to determine the distribution and content of minerals. However, as the exploration task continues and is used for a long time, the operator's arms are prone to fatigue, which increases discomfort and reduces the efficiency of the detection work.

[0003] Although the handheld electromagnetic detector in the prior art has gradually improved in performance and weight, there are still deficiencies in operation comfort and use convenience. Especially for long-time detection operations, the design of handheld detectors often focuses on the functionality of the device, ignoring ergonomic design, which causes operators to experience arm fatigue, soreness and other problems after continuous use. In order to solve this problem, some research attempts to alleviate the fatigue of the operator by optimizing the grip feeling of the detector handle. For example, the patent with publication number CN220851661U provides a handheld metal detector convenient to stretch, which includes a first telescopic rod, a second telescopic rod slidably installed inside the first telescopic rod, a third telescopic rod slidably installed inside the second telescopic rod, a detection head rotatably installed on the side of the first telescopic rod away from the second telescopic rod, a telescopic mechanism provided inside the first telescopic rod, a handheld mechanism provided outside the third telescopic rod, the handheld mechanism including a folding assembly and a clamping assembly, the clamping assembly being provided on the right side of the folding assembly, and the hand rest being capable of wrapping the entire arm, thereby facilitating multi-directional leverage.

[0004] However, adjusting only at the handle still cannot effectively alleviate the discomfort caused by long-time use, and the lack of proper support for the elbow, forearm and upper arm is one of the main factors leading to operator fatigue. Therefore, there is an urgent need for an improved design that can provide additional support and comfort to the user without affecting the functionality of the device, thereby improving the operator's experience during long-time use.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] To address the technical problem of insufficient support for the elbow, forearm, and upper arm during detector use, leading to operator fatigue and discomfort from prolonged use, this invention provides a handheld mineral electromagnetic detector. During use, an additional elbow support point is provided, forming a triangular support structure consisting of an elbow rest, a handheld mechanism, and the detection device. This handheld support helps distribute the force on the hand during use, reducing fatigue during extended exploration work and improving comfort and efficiency in exploration operations.

[0032] Please see Figures 1 to 3 The handheld electromagnetic detector for minerals includes: a detection device 1, an elbow support structure 2, and a handheld structure 3. The detection device 1 includes an operating unit and a detection unit. The detection unit is located at one end of the operating unit and is used to detect signals or substances. The elbow support structure 2 is located on the operating unit and has an elbow support space 201 on one side for receiving and supporting the elbow. The elbow support space 201 can be adjusted with the movement of the elbow to adapt to the movement of the operating unit during use. The handheld structure 3 is fixed to the side of the operating unit corresponding to the position of the elbow support space and is located between the elbow support structure 2 and the detection unit for hand gripping.

[0033] In this device, the detection device 1 consists of an operating unit and a detection unit. The detection unit is located at one end of the operating unit and is used to detect various signals or substances to achieve the detection function. To improve the convenience and comfort of operating the detection device 1, this solution is also equipped with an elbow support structure 2 and a handheld structure 3. The handheld structure 3 is fixed on the side of the operating unit corresponding to the position of the elbow support space and is located between the elbow support structure 2 and the detection unit. It is mainly for the operator's hand to hold. The elbow support structure 2 is installed on the operating unit and has an elbow support space 201 on one side. The elbow support space 201 can not only receive and support the operator's elbow, but also adjust accordingly with the movement of the elbow. This ensures that the elbow support space 201 can always adapt and provide comfortable support during the use of the operating unit, thereby reducing the operator's fatigue. This allows the operator to maintain a stable and comfortable grip posture when using the detection device 1 for a long time, thereby improving work efficiency and accuracy.

[0034] Please see Figure 1 In this embodiment, the operating unit includes a main rod 11 and a controller 12, and the detection unit includes a detection plate 13. The main rod 11 is connected to the controller 12 and the detection plate 13 respectively. The controller 12 controls the detection plate 13 to generate an electromagnetic field through wiring to conduct mineral resource exploration. In use, the operator generally holds the main rod 11 and conducts the exploration on foot.

[0035] To provide support for the operator's elbow, please refer to [link / reference]. Figure 1 and Figure 2 In this embodiment, the elbow support structure 2 includes three main components: a first support portion 21, a second support portion 22, and an elastic element 23. The first support portion 21 is connected to the operating unit. The second support portion 22 is movably disposed on the side of the first support portion 21 away from the operating unit, and its side together with the first support portion 21 forms the elbow support space 201. The other side of the second support portion 22 is connected to the elastic element 23. The elastic element 23 is used to provide support force to ensure that when the user uses the elbow support, the second support portion 22 can closely fit the user's elbow and upper arm, thereby reducing discomfort during support and providing a stable support effect.

[0036] In practical applications, the adjustment mechanism of the elbow support structure 2 allows the operator to adjust the elbow support angle according to personal comfort and the working environment. For example, when the operator needs to conduct surveys on terrain at different heights, they can adjust the relative position between the first support part 21 and the second support part 22 to adapt to different working postures. Furthermore, the adjustment function of the elastic element 23 allows the elbow support structure 2 to adapt to the operator's natural elbow movement, thus maintaining comfort during long-term work. Through this design, the elbow support structure 2 not only adapts to the differences in body shape among different users but also maintains comfort during prolonged use, greatly enhancing the user experience.

[0037] Please see Figures 2 to 4In one embodiment, the first support portion 21 includes a support ball 211, and the second support portion 22 includes a movable support block 221. Specifically, the support ball 211 is installed at the end of the controller 12 opposite to the probe plate 13. A first support groove 2111 and a movable groove 2112 are respectively provided on one side of the support ball 211. The movable support block 221 is disposed within the movable groove 2112 and rotates with the support ball 211, allowing the movable support block 221 to rotate within the movable groove 2112 for flexible position adjustment. A second support groove 2211 is provided on the side of the movable support block 221 corresponding to the first support groove 2111. The first support groove 2111 and the second support groove 2211 can cooperate with each other to form the elbow support space 2 for receiving and supporting the elbow. 01. This design allows the user's elbow to rest within the elbow support space 201 formed between the first support groove 2111 of the support ball 211 and the second support groove 2211 of the movable support block 221 when using the detection device 1. This provides a support point for the user's elbow. The movable support block 221 and the support ball 211 can rotate flexibly to adapt to different angles and positions, thus providing a stable support base. The other side of the movable support block 221 is connected to the groove wall of the movable groove 2112 through the elastic element 23, so that the movable support block 221 can maintain a certain elasticity during use, thereby providing appropriate resistance when the user adjusts the elbow position, ensuring the stability and comfort of the support.

[0038] In a more specific embodiment, main supports 212 are provided on both sides of the support ball 211. The main supports 212 serve as the mounting base for the support ball 211 and the movable support block 221. They are fixedly connected to the end of the housing of the controller 12. A rotating shaft 213 is fixedly installed between the two main supports 212. Collars 222 are provided on both sides of the movable support block 221. The collars 222 are sleeved on the rotating shaft 213. The movable support block 221 can rotate with the rotating shaft 213 through the collars 222. It can rotate around the rotating shaft 213 in the movable groove 2112, so that the elbow support space 201 can be adjusted with the elbow movement to adapt to the operation of the operating unit during use.

[0039] Furthermore, in some embodiments, the support ball 211 is rotatably connected to the rotating shaft 213. The spherical structure of the support ball 211 and its rotatable mounting configuration allow the device to adapt to various angle support requirements, providing additional flexibility. During use, the user can further adjust the angle between the forearm and the detector to meet the needs of different users, ensuring that the elbow support fits snugly against the user's elbow, thereby reducing pressure during use. In addition, a central support 214 is configured below the support ball 211, which is fixedly connected to the controller 12. The central support 214 fits snugly against the support ball 211, and its end face is designed with a frosted surface to increase friction when rotating with the support ball 211, thereby preventing the device from slipping. In other embodiments, the main support 212 can also be tightened with fasteners, and the support ball 211 can be adjusted to a suitable angle before being fixed.

[0040] Furthermore, in some embodiments, both the first support groove 2111 and the second support groove 2211 are arc-shaped grooves. The first support groove 2111 and the second support groove 2211 respectively conform to the physiological curves of the human forearm and upper arm, and can better fit the human forearm and upper arm. The side wall of the first support groove 2111 opposite to the movable groove 2112 is perpendicular to each other, which can limit the rotation range of the movable support block 221 within a certain angle to prevent discomfort or damage caused by excessive rotation.

[0041] To further enhance user comfort, in some embodiments, the inner walls of both the first support groove 2111 and the second support groove 2211 are lined with rubber, silicone, or cloth to ensure that the arm does not experience discomfort when supported.

[0042] Please see Figure 3 and Figure 4 Preferably, in this embodiment, the elastic element 23 includes a support spring 231, which is disposed within the movable groove 2112. One end of the support spring 231 is fixed to the movable support block 221, and the other end is fixedly connected to the groove wall of the movable groove 2112, providing elastic support for the movable support block 221. This allows the support spring 231 to be supported from behind when the arm is extended, indirectly supporting the upper arm and ensuring that the movable support block 221 always fits snugly against the user's arm, guaranteeing comfort.

[0043] To further protect the support spring 231, in some embodiments, the elastic element 23 also includes a protective folding piece 232. The protective folding piece 232 is disposed at the outer edge of the movable groove 2112, with its two ends fixedly connected to the movable support block 221 and the support ball 211, respectively. Its two sides are fitted against the groove wall of the movable groove 2112. When the movable support block 221 rotates, the protective folding piece 232 can extend or fold according to the state of the support block. It can be stably held outside the support spring 231, playing the role of dust prevention and protection of the support spring 231.

[0044] Please see Figure 1 , Figure 5 and Figure 6 In this embodiment, the handheld structure 3 includes a handle 31 and a control switch 32. The handle 31 is fixed to one side of the controller 12, and its position corresponds to the position of the first support groove 2111. The control switch 32 is mounted on the handle 31 and is electrically connected to the controller 12, having the function of starting and stopping the controller 12, allowing the operator to easily control the device. In addition, a grip groove is designed on the outer side of the handle 31 to improve the comfort of holding it.

[0045] To better facilitate the use of the support ball 211, in this embodiment, the handheld structure 3 further includes a telescopic rod 33. The telescopic rod 33 is vertically mounted on one side of the operating unit, with its telescopic shaft rotatably connected to one end of the handle 31. The other end of the handle 31 can face the elbow support structure 2 for easy use. The length of the telescopic rod 33 is adjustable, allowing users to adjust the position of the handle 31 according to their height and usage habits, resulting in a more personalized and comfortable user experience. To ensure the stability of the telescopic rod 33 during use, in one embodiment, the telescopic shaft of the telescopic rod 33 adopts a spiral structure, allowing the telescopic rod 33 to extend or shorten by rotating the handle 31. In another embodiment, the outer wall of the telescopic rod 33 is provided with multiple positioning holes, allowing users to insert positioning pins to fix the telescopic rod 33 in a specific position, preventing accidental slippage during use.

[0046] Working Principle: During use, the user grips the handle 31 and places their elbow within the elbow support space 201 formed between the first support groove 2111 of the support ball 211 and the second support groove 2211 of the movable support block 221. Depending on the user's body type, the support ball 211 can be rotated to adjust the angle of the elbow support space 201, adapting it to the natural position of the elbow. Simultaneously, the user can adjust the length of the telescopic rod 33 according to their height and usage habits to adjust the position of the handle 31. In this way, the support ball 211 and the movable support block 221 together form an elbow support point, creating a stable triangular support structure with the hand and the detector, effectively reducing hand stress and improving comfort during extended work periods. When detecting at different positions, as the angle of the detection device 1 changes, the movable support block 221 can rotate around the pivot 213 for adaptive adjustment, and the support spring 231 provides elastic support, ensuring that the elbow support space 201 always fits snugly against the elbow, upper arm, and forearm.

[0047] This invention comprises a detection device 1, an elbow support structure 2, and a handheld structure 3. The handheld structure 3 is fixed to the side of the operating unit corresponding to the position of the elbow support space, for the operator's hand to grip. The elbow support structure 2 is mounted on the operating unit, and has an elbow support space 201 on one side. The elbow support space 201 not only accommodates and supports the operator's elbow, but also adjusts accordingly with the movement of the elbow, ensuring that the elbow support space 201 can always adapt and provide comfortable support during the use of the operating unit, thereby reducing operator fatigue. This allows the operator to maintain a stable and comfortable grip posture when using the detection device 1 for a long time, thereby improving work efficiency and accuracy.

[0048] During use, this device can provide an additional elbow support point for the detector, forming a triangular support structure consisting of elbow support structure 2, handheld structure 3 and detection device 1. This handheld support method helps to distribute the force on the hand when holding the device, making it less likely to cause fatigue during long-term exploration work, and improving the comfort and efficiency of exploration operations.
