Description

Technical Field

[0001] The invention relates to the technical field of detection tools, and in particular to a handheld mineral electromagnetic detector. Background Art

[0002] As a convenient detection tool, handheld electromagnetic mineral detectors are widely used in geological exploration, mineral resource exploration and other fields. Its working principle is mainly to detect the changes in the electromagnetic field generated by underground minerals through electromagnetic induction technology, helping operators to determine the distribution and content of minerals. However, with the continuous and long-term use of exploration tasks, the operator's arms are prone to fatigue, resulting in increased discomfort and reduced detection efficiency.

[0003] Although the handheld electromagnetic detectors in the prior art have gradually improved in performance and weight, they are still insufficient in terms of operational comfort and ease of use. In particular, for operations that require long-term detection, the design of handheld detectors often focuses on the functionality of the equipment, while ignoring ergonomic design, causing operators to experience problems such as arm fatigue and soreness after continuous use. In order to solve this problem, some studies have attempted to alleviate operator fatigue by optimizing the grip of the detector handle. For example, the patent CN220851661U provides a handheld metal detector that is easy to telescope, including a first telescopic rod, a second telescopic rod is slidably installed inside the first telescopic rod, a third telescopic rod is slidably installed inside the second telescopic rod, a detection head is rotatably installed on the side of the first telescopic rod away from the second telescopic rod, a telescopic mechanism is provided inside the first telescopic rod, and a handheld mechanism is provided outside the third telescopic rod. The handheld mechanism includes a folding component and a clamping component, and the clamping component is arranged on the right side of the folding component. The hand rest can wrap the arm as a whole, which is convenient for multi-directional leverage.

[0004] However, adjusting the handle alone cannot effectively alleviate the discomfort caused by long-term use. The lack of proper support for the elbow, forearm and upper arm is one of the main factors leading to operator fatigue. Therefore, an improved design is urgently needed to provide additional support and comfort to the user while ensuring that the function of the equipment is not affected, thereby improving the operator's experience during long-term use.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In order to solve the technical problem that the lack of proper support for the elbows, forearms and upper arms when using the detector makes the operator easily fatigued and cannot effectively reduce the discomfort caused by long-term use, the present invention provides a handheld mineral electromagnetic detector. During use, an additional elbow support point can be provided for the detector to form a triangular support structure consisting of an elbow support structure, a handheld structure and a detection device. This handheld support method helps to disperse the force on the hand when holding, making it less likely to cause fatigue during long-term surveying work, thereby improving the comfort and work efficiency of exploration operations.

[0021] See also Figures 1 to 3The handheld electromagnetic detector for minerals comprises: a detection device 1, an elbow support structure 2 and a handheld structure 3. The detection device 1 comprises an operating unit and a detection unit. The detection unit is arranged at one end of the operating unit for detecting signals or substances. The elbow support structure 2 is arranged on the operating unit, and one side of the elbow support structure 2 is provided with an elbow support space 201 for receiving and supporting the elbow.

The handheld structure 3 is fixed to the side of the operating unit corresponding to the position of the elbow support space, and is arranged between the elbow support structure 2 and the detection unit for being held by the hand.

[0022] In the present device, the detection device 1 is composed of an operating unit and a detection unit, wherein the detection unit is arranged at one end of the operating unit, and is used to detect various signals or substances to realize the detection function; in order to improve the convenience and comfort of the operation of the detection device 1, the present solution is also equipped with an elbow support structure 2 and a hand-held structure 3, the hand-held structure 3 is fixed to the side of the operating unit corresponding to the position of the elbow support space, and is arranged between the elbow support structure 2 and the detection unit, and is mainly for the operator's hand to hold; the elbow support structure 2 is installed on the operating unit, and one side of it has an elbow support space 201, the elbow support space 201 can not only accommodate and support the operator's elbow, but also can be adjusted accordingly with the movement of the elbow, to ensure that during the use of the operating unit, the elbow support space 201 can always adapt and provide comfortable support, thereby reducing the operator's fatigue; so that the operator can maintain a stable and comfortable holding posture when using the detection device 1 for a long time, thereby improving work efficiency and accuracy.

[0023] See also Figure 1 In this embodiment, the operating unit includes a main rod 11 and a controller 12, and the detection unit includes a probe 13. The main rod 11 is connected to the controller 12 and the probe 13 respectively. The controller 12 controls the probe 13 to generate an electromagnetic field through a line to survey mineral resources. When in use, the operator generally holds the main rod 11 and walks to conduct surveys.

[0024] To achieve support for the operator's elbow, refer to Figure 1 and Figure 2In this embodiment, the elbow support structure 2 includes three main components: a first support part 21, a second support part 22 and an elastic member 23. The first support part 21 is connected to the operating unit. The second support part 22 is movably arranged on a side of the first support part 21 away from the operating unit, and one side of the second support part 22 forms the elbow support space 201 together with the first support part 21. The other side of the second support part 22 is connected to the elastic member 23. The elastic member 23 is used to provide supporting force to ensure that when the user uses the elbow support, the second support part 22 can fit closely to the user's elbow upper arm, thereby reducing discomfort during support and providing a stable supporting effect.

[0025] In actual applications, the adjustment mechanism of the elbow support structure 2 allows the operator to adjust the elbow support angle according to personal comfort and working environment. For example, when the operator needs to survey terrains at different heights, the relative position between the first support part 21 and the second support part 22 can be adjusted to adapt to different working postures. In addition, the adjustment function of the elastic member 23 enables the elbow support structure 2 to adapt to the natural movement of the operator's elbow, thereby maintaining comfort during long-term work. Through such a design, the elbow support structure 2 can not only adapt to the differences in body shapes of different users, but also maintain comfort during long-term use, greatly improving the user experience.

[0026] See also Figures 2 to 4In one embodiment, the first support part 21 includes a support ball 211, and the second support part 22 includes a movable support block 221. Specifically, the support ball 211 is installed at the end of the controller 12 away from the search plate 13, and one side of the support ball 211 is respectively provided with a first support groove 2111 and a movable groove 2112 that are connected; the movable support block 221 is arranged in the movable groove 2112 and rotates with the support ball 211, so that the movable support block 221 can rotate in the movable groove 2112 to flexibly adjust the position, and the second support groove 2211 is provided on the side of the movable support block 221 corresponding to the first support groove 2111, and the first support groove 2111 and the second support groove 2211 can cooperate with each other to form the elbow support space 2111 for receiving and supporting the elbow. 01. This design allows the user to place his elbow in 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, providing 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, thereby providing a stable support basis, and the other side of the movable support block 221 is connected to the groove wall of the movable groove 2112 through the elastic member 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.

[0027] In a more specific embodiment, main brackets 212 are provided on both sides of the support ball 211, and the main brackets 212 are used as the installation basis for the support ball 211 and the movable support block 221, and are fixedly connected to the end of the shell of the controller 12, and a rotating shaft 213 is fixedly installed between the two main brackets 212, and rings 222 are provided on both sides of the movable support block 221, and the rings 222 are sleeved on the rotating shaft 213. The movable support block 221 can realize rotation with the rotating shaft 213 through the rings 222, and can rotate around the rotating shaft 213 in the movable groove 2112, so that 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.

[0028] Further, in some embodiments, the support ball 211 is rotatably connected to the rotation shaft 213 via the rotation shaft 213. The spherical structure of the support ball 211 and its rotatable installation arrangement enable the device to adapt to the support requirements of various angles, which provides additional flexibility. When using, the user can further adjust the angle between the forearm and the detector to meet the use requirements of different users, ensuring that the elbow support can fit the user's elbow tightly, thereby reducing the sense of oppression during use. In addition, a central bracket 214 is configured below the support ball 211, and the central bracket 214 is fixedly connected to the controller 12. The central bracket 214 fits tightly with the support ball 211, and its end face is designed with a frosted surface to increase the friction when rotating with the support ball 211, thereby preventing the device from sliding. In other embodiments, the main bracket 212 can also be tightened by fasteners, and the support ball 211 can be fixed after adjusting it to a suitable angle.

[0029] Furthermore, in some embodiments, the first support groove 2111 and the second support groove 2211 are both arc-shaped grooves, and 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 groove wall on one side opposite to the first support groove 2111 and the movable groove 2112 is perpendicular to each other, and the rotation range of the movable support block 221 can be limited to a certain angle to prevent discomfort or injury caused by excessive rotation.

[0030] To increase the comfort of use, further, in some embodiments, the inner wall surfaces of the first support groove 2111 and the second support groove 2211 are padded with rubber, silicone or cloth as linings to ensure that the arm does not feel discomfort when supporting.

[0031] See also Figure 3 and Figure 4 Preferably, in this embodiment, the elastic member 23 includes a support spring 231, which is arranged in the movable groove 2112, one end of which is fixed to the movable support block 221, and the other end is fixedly connected to the groove wall of the movable groove 2112, so as to provide elastic support force for the movable support block 221. When the arm is extended, the movable support block 221 can be supported from the rear, and the upper arm can be indirectly supported, so that the movable support block 221 is always close to the user's arm to ensure comfort.

[0032] In order to protect the support spring 231, further, in some embodiments, the elastic member 23 also includes a protective folding sheet 232, and the protective folding sheet 232 is arranged at the outer edge of the movable groove 2112, and its two ends are respectively fixedly connected to the movable support block 221 and the support ball 211, and its two sides are arranged in contact with the groove wall of the movable groove 2112. When the movable support block 221 rotates, the protective folding sheet 232 can be extended or folded according to the state of the support block, and it can be stably maintained on the outside of the support spring 231, so as to play a role in dust prevention and protection of the support spring 231.

[0033] See also 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 installed on the handle 31. The control switch 32 is electrically connected to the controller 12 and has the function of starting and shutting down the controller 12, so that the operator can easily control the device. In addition, a grip groove is designed on the outside of the handle 31 to improve the comfort when holding.

[0034] In order to better cooperate with the use of the support ball 211, in this embodiment, the handheld structure 3 also includes a telescopic rod 33, which is vertically installed on one side of the operating unit, and the end of its telescopic shaft is rotatably connected to one end of the handle 31, and the other end of the handle 31 can be oriented toward the elbow support structure 2 for easy use. The length of the telescopic rod 33 is adjustable, so that the user can adjust the position of the handle 31 according to personal height and usage habits, thereby achieving a more personalized and comfortable use experience. In order 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, and the telescopic rod 33 can be extended or shortened by rotating the handle 31. In another embodiment, a plurality of positioning holes are provided on the outer wall of the telescopic rod 33, and the user can fix the telescopic rod 33 in a specific position by inserting a positioning pin to prevent it from accidentally sliding during use.

[0035] Working principle: When in use, the user holds the handle 31 and places the elbow in 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. According to the body shape of the user, the support ball 211 can be rotated to adjust the angle of the elbow support space 201 to adapt it to the natural position of the elbow. At the same time, the user can adjust the length of the telescopic rod 33 according to personal 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 constitute an elbow support point, and together with the hand and the detector, form a stable triangular support structure, effectively reducing the force on the hand and improving the comfort of long-term operation. When detecting at different positions, as the angle of the detection device 1 changes, the movable support block 221 can rotate around the rotating shaft 213 to make adaptive adjustments, and provide elastic support force through the support spring 231 to ensure that the elbow support space 201 is always in close contact with the upper arm and forearm of the elbow.

[0036] The present invention provides a detection device 1, an elbow support structure 2 and a hand-held structure 3. The hand-held structure 3 is fixed to a side of the operating unit corresponding to the position of the elbow support space, and is used for the operator to hold the hand. 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 accommodate and support the operator's elbow, but also can be adjusted accordingly with the movement of the elbow, ensuring that during the use of the operating unit, the elbow support space 201 can always adapt and provide comfortable support, thereby reducing the operator's fatigue; allowing the operator to maintain a stable and comfortable holding posture when using the detection device 1 for a long time, thereby improving work efficiency and accuracy.

[0037] During use, the device can provide an additional elbow support point for the detector, forming a triangular support structure consisting of an elbow support structure 2, a handheld structure 3 and a detection device 1. This handheld support method helps to disperse the force on the hand when holding, making long-term surveying work less likely to cause fatigue, thereby improving the comfort and work efficiency of the exploration operation.
