[0051] Embodiment one

[0052] Refer to the attached Figure 1 to the attached Figure 4 , the embodiment provides a folding structure, which can have greater activity space in the unfolded state, without hindering the walking of the legs during detection operation.

[0053] Specifically, it includes support seat 100, which has no special shape requirement, and the grid-shaped hollow structure shown in the figure is also provided with a plurality of reinforcing ribs, which has good overall support strength.

[0054] The two sides (such as the left and right sides shown in the figure) of one reverse corresponding of the support seat 100 are respectively provided with two support arms 300 hinged thereto, and the included angle between the two support arms 300 on each side is an acute angle or parallel corresponding, that is, the support arm 300 can swing within a certain amplitude with the hinge point as the center. When the support arm 300 is unfolded in the horizontal direction, the included angle a between them is an acute angle or parallel corresponding, so that the two support arms 300 can be as close as possible, or reach parallel corresponding, while the two support arms 300 farther apart can form a larger obtuse angle, even 180 degrees angle, so that the personnel walking in this area is more convenient during detection operation, and the legs will not touch the support arm 300. The traditional structure is that the support arms are at right angles, so that the activity space of the legs is very limited.

[0055] In addition, it should be noted that four support arms 300 are provided because a certain support strength is needed, especially when finally assembled and used, under the joint action of other components, it will not be easily bent and deformed. It is also convenient for separate disassembly and replacement, and reduces the cost of replacement and maintenance.

[0056] The support seat 100 limits the swing of the support arm 300 towards the detection direction (i.e. Figure 3 The direction shown in the figure towards the ground) through the blocking piece 101, so as to ensure that the support arm 300 will not hang down downward, and keep the posture of stretching horizontally or close to horizontally.

[0057] Of course, the blocking piece 101 shown in the figure is used to limit the upward lifting of the end of the support arm 300, that is, to prevent the free end of the support arm 300 from sagging downward, which is located above the support arm 300 in the direction close to the support base 100. In addition, it can also be arranged in the direction away from the support base 100 and below the support arm 300 to achieve the function of lifting and also play the role of limiting and blocking.

[0058] The position of the blocking piece 101 above the end of the support arm 300 can more effectively play the role of limiting and blocking, and can disperse the weight of the support arm 300 to the support base 100. In addition, the grid structure and several reinforcing ribs of the support base 100 can effectively bear the weight of multiple support arms 300, which is better than the structure of the lifting and dispersion mode of the blocking piece 101 arranged below.

[0059] Through the above structure, the folding and storage of the support arm 300 can be realized, and sufficient space can be provided for personnel to walk. Compared with the traditional complex bending structure, the structure is simpler, the space is larger, and it is more convenient.

[0060] In addition, in order to facilitate disassembly and replacement, the hinged end of the support arm 300 is hinged with the support base 100 through the hinged seat 200 which is detachably connected with the support arm 300. As can be seen from the figure, the hinged seat 200 is more robust, and the support arm 300 can be coaxially inserted into the hinged seat 200. Not only can it realize convenient disassembly, but also can prolong the service life by using a more solid hinged seat 200 to prevent the support arm 300 from being damaged due to excessive force. By replacing the support arm 300 alone, the insertion of the two is also flexible and convenient.

[0061] Referring to the accompanying Figure 9 and the accompanying Figure 10 In this embodiment, in order to realize positioning in the storage state, each support arm 300 or each hinged seat 200 realizes folding positioning through the clamping mechanism 400. That is, when the support arms 300 are close to each other and the axial direction is the same direction, the clamping mechanism 400 can fix the extension to achieve stable storage effect.

[0062] Specifically, the clamping mechanism 400 includes clamping piece one 401 and clamping piece two 402 which are clamped opposite to each other and cannot be easily separated after being clamped. The clamping piece one 401 is fixedly arranged on one end of the support arm 300 or the hinged seat 200 close to the hinge, which is shown in the figure as being arranged above the hinged seat 200. The clamping piece two 402 is arranged on one end of the support base 100 close to the clamping piece one 401. When the two are gradually close to each other, they can be clamped opposite to each other and fixed.

[0063] In the above structure, in order to facilitate the control of the docking and separation, the clamping piece two 402 is hinged with the support seat 100, the clamping piece two 402 can swing with the hinge as the center, and the side of the clamping piece two 402 away from the opposite clamping direction is elastically connected with the support seat 100 through the elastic element 403 (actually a compression spring is used).

[0064] When the clamping piece two 402 is pressed, the compression spring is compressed, the clamping piece two 402 swings with the hinge as the center, and the other end is lifted in the opposite direction (commonly known as opening), at this time, the clamping piece two 402 is separated from the clamping piece one 401 to stretch. Conversely, when the clamping piece one 401 is closed, the clamping piece two 402 is released, the compression spring is reset by its own elasticity, and the clamping piece two 402 is reset by the compression spring, so as to realize the mutual adhesion with the clamping piece one 401, and finally realize the clamping and fixing. Of course, as can be seen from the figure, the compression spring can be positioned by a limiting column or a chamber to prevent displacement and fall after being stressed.

[0065] As a preferred, the acute angle between the two support arms 300 on one side of the support seat 100 is consistent with the acute angle between the two support arms 300 on the other side of the support seat 100. The above structure can form a symmetrical structure, which is more beautiful after stretching, and is also beneficial to processing.

[0066] Embodiment two

[0067] Referring to the accompanying Figure 5 to the accompanying Figure 8 The purpose of the embodiment is to provide a metal detector.

[0068] Specifically, it includes a detection host 500 and a detection cable 502, and the detection host 500 is arranged on the side of the support seat 100 away from the detection direction in the above folding structure.

[0069] That is, the upper position shown in the figure, which can be connected with the support seat 100 through a connecting rod 501. Of course, the connecting rod 501 can be telescopic to meet the requirements of different working heights. The connecting rod 501 can be inserted with the support seat 100, can be threaded, or can be pin shaft connection, and can realize the two fixed connections, and through the detachable connection, it is also convenient to disassemble and store. The structure shown in the figure is threaded, and the bottom surface of the support seat 100 is provided with a thread hole, and after the connecting rod 501 is inserted with the support seat 100, the bolt is inserted into the thread hole to finally be threaded with the bottom end of the connecting rod 501 and fastened.

[0070] The free end of the two support arms 300 located at one side of the support base 100 and the free end of the two support arms 300 located at the other side of the support base 100 are respectively provided with terminal support arms 600, and the terminal support arms 300 are movably connected with the support arms 300 through joint members 700. When the two terminal support arms 600 located at one side of the support base 100 are stretched (i.e. arranged in opposite directions), the two terminal support arms 600 located at the other side are also stretched, so as to form a frame shape. The detection cable 502 is limited at the free end of each terminal support arm 600 and electrically connected with the detection host 500, and finally surrounds a closed rectangular frame to detect the metal object on the ground.

[0071] It should be noted that the electrical connection mainly includes wired electrical connection and wireless electrical connection, and the two types of electrical connection have advantages and disadvantages. The wired electrical connection has more stable data transmission, but requires line connection. The wireless electrical connection is more convenient, and the operator can carry the detection host by hanging the neck or carrying on the shoulder, but the data transmission is easily interfered and terminated. Users can choose according to needs.

[0072] The detection cable 502 can be connected with the wire slot 602 on the terminal support arm 600 to limit the effect, and one of the terminal support arms 600 is further provided with a three-way joint 601 for penetrating the detection cable 502, so as to stably connect the storage box and facilitate electrical connection with the detection host 500.

[0073] In the above structure, the terminal support arms 600 located at both sides of the support base 100 can also have an angle, such as the obtuse angle bending to the left and right sides as shown in the figure, so as to have a better supporting effect and prevent the free end of the terminal support arm 600 from bending and deforming under the tightening of the detection cable 502.

[0074] Referring to the drawings Figure 11 and the drawings Figure 12 In the embodiment, the joint member 700 plays a role of rotating connection and positioning, which includes a joint part one 710 detachably connected with the support arm 300 and a joint part two 720 detachably connected with the terminal support arm 600. The joint part one 710 and the joint part two 720 are hingedly connected with each other, so that the two joint parts can be close to each other or away from each other, so as to realize the folding storage of the terminal support arm 600.

[0075] In order to realize the angle fixing, the joint part one 710 and the joint part two 720 are respectively provided with space one 711 and space two 721 which can be communicated correspondingly, when the two spaces are communicated correspondingly, it is the state that the joint part one 710 and the joint part two 720 are stretched, or the state that the stretching is maximized. The space one 711 or the space two 721 is provided with elastic member two 701 (actually, compression spring is adopted), which can be embedded and placed in the space, one end of the elastic member two 701 is provided with control knob 730, the control knob 730 is pressed and touched in the space one 711 and the space two 721 and moves.

[0076] Specifically, when the joint part one 710 and the joint part two 720 are stretched, the space one 711 and the space two 721 are communicated correspondingly, the compression spring and the control knob 730 can be placed in the two spaces. At this time, the joint part one 710 and the joint part two 720 will be blocked and cannot rotate with the hinge as the center.

[0077] Conversely, only when the control knob 730 is pressed to suppress the compression spring and make it in one of the spaces, the joint part one 710 and the joint part two 720 can rotate without being blocked, at this time, the folding storage effect can be realized.

[0078] Working principle:

[0079] The four supporting arms 300 can be folded and stored with the hinge as the center, and are positioned through the clamping mechanism. Moreover, the included angle between the two supporting arms 300 on the two sides of the supporting seat 100 is an acute angle or parallel correspondence, a larger space can be formed instead of the traditional 90-degree space. A larger walking space is provided for the detection personnel, and the structure is also simpler. The end supporting arm 600 on each supporting arm 300 can also be folded and stored, and has a good supporting effect when stretched. The detection personnel can move the detection host by holding it with one hand, and the operation is very convenient.

[0080] By adopting the above technical scheme, the utility model has the advantages of the following beneficial effects:

[0081] Because the supporting arms no longer adopt the layout mode of right angle correspondence, but the supporting arms on the two sides of the supporting seat correspond with each other as an acute angle or parallel correspondence, the included angle between the two supporting arms which are far apart is larger, a obtuse angle or 180-degree angle is formed, the personnel can move in the area without being blocked, the leg movement space is sufficient, and the use is more convenient.

[0082] Although the utility model has been described above with reference to the embodiments, various modifications can be made to it and equivalent components can be substituted for the components thereof without departing from the scope of the utility model. In particular, the features of the embodiments disclosed by the utility model can be combined with each other in any manner as long as there is no structural conflict, and the combinations of the features are not exhaustively described in the specification only for the purpose of omitting the length and saving the resources. Therefore, the utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
