[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] Reference below Figure 1-Figure 4 A magnetic base and a welding robot according to an embodiment of the present invention are described.

[0035] like Figure 1-Figure 4 As shown, the magnetic base of the embodiment of the present invention includes a base body 1, a magnet 2, a magnetic conductor 3 and a non-magnetic conductor.

[0036] The magnet 2 is connected to the base body 1 and can rotate relative to the base body 1 in a first direction (such as Figure 1 The magnet 2 has a rotation direction along the second direction (as shown in the up and down direction). Figure 1 The positive and negative poles are arranged in the horizontal direction (shown in FIG. 1 ), and the second direction is orthogonal to the first direction. The magnetic conductor 3 and the non-magnetic conductor are both connected to the base, and at least two magnetic conductors 3 and at least two non-magnetic conductors are arranged one by one along the circumference of the magnet 2 and surround the outer periphery of the magnet 2.

[0037] Specifically, Figure 1 As shown, the base body 1 is preferably but not limited to being horizontally arranged, the magnet 2 is connected to the base body 1 and is at least partially located at the bottom of the base body 1, the magnet 2 has a positive pole and a negative pole arranged in the horizontal direction, and the magnet 2 can rotate in the vertical direction relative to the base body 1.

[0038] The magnetic conductor 3 and the non-magnetic conductor (not shown in the figure) are both connected to the base and are at least partially located at the bottom of the base body 1. There are at least two magnetic conductors 3 and non-magnetic conductors, preferably but not limited to two. The two magnetic conductors 3 and the two non-magnetic conductors are arranged one by one along the circumference of the magnet 2 and surround the outer periphery of the magnet 2. In other words, the magnetic conductors 3 and the non-magnetic conductors are alternately arranged along the circumference of the magnet 2 and surround the outer periphery of the magnet 2.

[0039] Preferably, the two magnetizers 3 are arranged at intervals along the left-right direction, the two non-magnetizers are arranged at intervals along the front-back direction, a non-magnetizer is provided between the front ends of the two magnetizers 3, and another non-magnetizer is provided between the rear ends of the two magnetizers 3. The two magnetizers 3 and the two non-magnetizers surround to form a receiving space, at least part of the magnet 2 is located in the receiving space, and can rotate around the vertical direction in the receiving space.

[0040] The magnetic base of the embodiment of the present invention is provided with a magnet, a magnetic conductor and a non-magnetic conductor on the base body, and the magnet has an open position and a closed position during rotation.

[0041] In the open position, the positive and negative poles of the magnet are arranged horizontally relative to the corresponding magnetizers. In other words, the two magnetizers are located in the arrangement direction of the positive and negative poles. In other words, the magnets rotate to a position where the arrangement direction of the positive and negative poles coincides with the direction in which the two magnetizers are arranged at intervals. At this time, the magnetic lines of force of the magnet pass through the magnetizers to form a closed loop. The magnetizers have magnetic force and can be adsorbed on the work surface, thereby fixing the magnetic base on the work surface.

[0042] In the closed position, the positive and negative poles of the magnet are arranged horizontally relative to the corresponding non-magnetic conductors. In other words, the two non-magnetic conductors are located in the arrangement direction of the positive and negative poles. In other words, the magnet rotates to a position where the arrangement direction of the positive and negative poles coincides with the direction in which the two non-magnetic conductors are arranged at intervals. At this time, the non-magnetic conductor divides the magnetic force lines of the magnet, the magnetic conductor has no magnetic force, and the magnetic base moves on the working surface or leaves the working surface.

[0043] Therefore, the magnetic base of the embodiment of the present invention can control the opening and closing of the magnetic force, which is convenient for disassembling and assembling the magnetic base from the work surface, and adjusting the position of the magnetic base on the work surface.

[0044] Preferably, the magnetic conductor 3 is made of a magnetic material, the non-magnetic conductor is made of copper, the working surface is made of a metal material that can be magnetically attracted, and the magnet 2 is made of neodymium iron boron.

[0045] It should be noted that when there are two magnets 3 and two non-magnets, the spacing arrangement direction of the two magnets 3 is orthogonal to the spacing arrangement direction of the two non-magnets, and the magnet 2 can switch between the open position and the closed position by rotating 90°. However, the magnet 2 is not limited to rotating 90° when switching between the open position and the closed position. According to the size and length of the magnet 3 and the non-magnetic conductor, there is a situation where the magnet 2 can be switched when it is rotated less than 90°.

[0046] It can be understood that the number of the magnetic conductor and the non-magnetic conductor is not limited to two. In other embodiments, the number of the magnetic conductor and the non-magnetic conductor is four or six.

[0047] It should be noted that the base body 1 is not limited to a horizontal setting. In other words, the magnetic base is not limited to a horizontal setting. Depending on the position and posture of the working surface, the magnetic base and the base body can also be vertically set or tilted.

[0048] In some embodiments, the magnet 2 has a first connection end and a free end 21 that are arranged opposite to each other along a first direction, and the first connection end is connected to the base body 1. The magnetic conductor 3 has a second connection end 31 and an abutting end 32 that are arranged opposite to each other along the first direction, and the second connection end 31 is connected to the base body 1. The end surface of the free end 21 along the first direction is located between the end surface of the base body 1 and the end surface of the abutting end 32 along the first direction.

[0049] like Figure 1 As shown, the upper end of the magnet 2 is the first connection end, the lower end of the magnet 2 is the free end 21 , and the upper end of the magnet 2 is connected to the base body 1 .

[0050] The upper end of the magnetizer 3 is the second connection end 31 , the lower end of the magnetizer 3 is the abutment end 32 , the upper end of the magnetizer 3 is connected to the base body 1 , and the lower end surface of the magnetizer 3 is used to abut and adsorb the working surface.

[0051] The lower end surface of the magnet 2 is located between the lower end surface of the magnetizer 3 and the base body 1. In other words, the lower end surface of the magnet 2 is higher than the lower end surface of the magnetizer 3 to prevent the magnet 2 from directly adsorbing the working surface.

[0052] Furthermore, the upper end of the non-magnetic body is connected to the base body 1, and the lower end surface of the non-magnetic body is located between the lower end surface of the magnet 2 and the lower end surface of the magnetic body 3, or the lower end surface of the non-magnetic body is flush with the lower end surface of the magnet 2, or the lower end surface of the non-magnetic body is flush with the lower end surface of the magnetic body 3, preferably, the lower end surface of the non-magnetic body is flush with the lower end surface of the magnetic body 3.

[0053] In some embodiments, among at least two magnetic conductors 3, any one magnetic conductor 3 is arranged in a spaced relationship with another magnetic conductor 3 along the second direction. Among at least two non-magnetic conductors, any one non-magnetic conductor is arranged in a spaced relationship with another non-magnetic conductor along the second direction.

[0054] like Figure 1 As shown, two magnetic conductors 3 are arranged at intervals along the left-right direction, and two non-magnetic conductors are arranged at intervals along the front-back direction. A non-magnetic conductor is provided between the front ends of the two magnetic conductors 3, and another non-magnetic conductor is provided between the rear ends of the two magnetic conductors 3.

[0055] It can be understood that the magnetic conductors and non-magnetic conductors are not limited to two. In other embodiments, the magnetic conductors and non-magnetic conductors are arranged in multiple groups, each group of magnetic conductors includes two magnetic conductors arranged at intervals along the horizontal direction, and each group of non-magnetic conductors includes two non-magnetic conductors arranged at intervals along the horizontal direction. Along the circumferential arrangement direction of the magnetic conductors and non-magnetic conductors, corresponding non-magnetic conductors are provided between two adjacent magnetic conductors, and corresponding magnetic conductors are provided between two adjacent non-magnetic conductors.

[0056] Preferably, the cross section of the magnet 2 is circular, in other words, the magnet 2 is cylindrical and extends in the vertical direction. The positive pole and the negative pole are arranged along the radial direction of the magnet 2. This facilitates the magnet 2 to rotate and switch between the open position and the closed position.

[0057] Two magnetizers 3 and two non-magnetizers are arranged one by one along the circumference of magnet 2 and surround the outer circumference of magnet 2. Two magnetizers 3 are arranged along the radial direction of magnet 2 and two non-magnetizers are also arranged along the radial direction of magnet 2. The cross-section of magnetizer 3 and the cross-section of non-magnetizer are both arcs extending along the circumference of magnet 2. There is a gap between the inner circumference of magnetizer 3 and the outer circumference of magnet 2, and there is a gap between the inner circumference of non-magnetizer and the outer circumference of magnet 2. This makes it easy for magnet 2 to rotate and avoids collision and friction caused by interference.

[0058] The extension length of the non-magnetic conductor along the circumferential direction is smaller than the extension length of the magnetic conductor 3 along the circumferential direction.

[0059] The circumferential end faces of the non-magnetic conductor and the magnetic conductor 3 can both be planes, or one can be a convex surface and the other can be a concave surface. Preferably, the circumferential end face of the magnetic conductor 3 is a convex arc surface, and the circumferential end face of the non-magnetic conductor is a concave arc surface. The circumferential end face of the magnetic conductor 3 fits in the corresponding circumferential end face of the corresponding non-magnetic conductor, so that the non-magnetic conductor and the magnetic conductor 3 can limit each other to ensure installation stability.

[0060] It can be understood that the cross-section of the magnet is not limited to a circle, and the cross-section of the magnetizer and the non-magnetizer is not limited to an arc. In other embodiments, the cross-section of the magnet is a polygon, and the cross-sections of the magnetizer and the non-magnetizer are both straight bars, or one of the magnetizer and the non-magnetizer is a straight bar, and the other is L-shaped or quasi-L-shaped, and the magnetizer and the non-magnetizer are arranged in a polygon that matches the cross-sectional shape of the magnet.

[0061] In some embodiments, the magnetic base of the embodiment of the present invention also includes a rotating seat 4, the base body 1 is provided with a mounting hole that penetrates the base body 1, the rotating seat 4 is embedded or penetrated in the mounting hole, and is connected to the magnet 2, and the rotating seat 4 can be driven to rotate relative to the base body 1 around a first direction to drive the magnet 2 to rotate around the first direction.

[0062] like Figure 1As shown, the base body 1 is provided with a mounting hole which passes through the base body 1 in the vertical direction, the rotating seat 4 can be arranged so that the lower end is embedded in the mounting hole, the upper end of the magnet 2 is also located in the mounting hole and is connected to the lower end of the rotating seat 4, the rotating seat 4 can also be arranged to be penetrated in the mounting hole, the lower end of the rotating seat 4 extends out from the bottom surface of the base body 1 and is connected to the upper end of the magnet 2, so that the magnet 2 is indirectly connected to the base body 1 through the rotating seat 4.

[0063] The rotating seat 4 can be driven to rotate in a vertical direction relative to the base body 1, thereby driving the magnet 2 to rotate in a vertical direction. Preferably, the cross section of the rotating seat 4 is circular, and the rotating seat 4 and the magnet 2 are coaxially arranged.

[0064] Furthermore, the upper end of the magnetizer 3 is penetrated through the base body 1. In other words, the base body 1 is provided with an arc hole that penetrates the base body 1 along the vertical direction, and the arc hole extends along the circumference of the rotating seat 4. At least two arc holes surround the outer circumference of the rotating seat 4, and at least two magnetizers 3 are penetrated in the at least two arc holes in a one-to-one manner.

[0065] The non-magnetic conductor can be arranged with its upper end penetrating the base body 1, or the non-magnetic conductor can be arranged with its upper end surface abutting against the bottom surface of the base body 1, and connected with two adjacent magnetic conductors 3 by plugging or snapping through the concave surfaces at both ends of the arc extension direction.

[0066] In some embodiments, the magnetic base of the embodiment of the present invention also includes a driving member 7, which is directly connected to the rotating seat 4, or the driving member 7 is arranged on the base body 1 and is indirectly connected to the rotating seat 4. The driving member 7 is used to drive the rotating seat 4 to rotate relative to the base body 1 around a first direction.

[0067] like Figure 2 As shown, the driving member 7 is arranged on the base body 1 and is indirectly connected to the rotating seat 4. The driving member 7 can adopt a rotating driving member such as a rotating handle, a rotating motor, etc., and is indirectly connected to the rotating seat 4 through a transmission mechanism such as a pull rope 5, a gear transmission mechanism, a chain transmission mechanism, a belt transmission mechanism, etc. The driving member 7 can also adopt a linear driving member such as a linear module, a telescopic cylinder, etc., and is indirectly connected to the rotating seat 4 through a transmission mechanism such as a pull rope 5, a gear rack conveyor, etc., to drive the rotating seat 4 to rotate in a vertical direction relative to the base body 1, so that the magnet 2 can switch between the open position and the closed position.

[0068] It is understandable that the driving member is not limited to being disposed on the base body. In other embodiments, the driving member is directly connected to the rotating seat to drive the rotating seat to rotate in a vertical direction. The driving member is preferably but not limited to a rotating handle, a rotating clamp disposed on an external component, or a rotating motor, etc.

[0069] In some embodiments, the magnetic base of the embodiment of the present invention further includes a pull rope 5 and a mounting member 6, the mounting member 6 is disposed on the rotating seat 4, the pull rope 5 is connected to the mounting member 6, and thus connected to the rotating seat 4, or the pull rope 5 is sandwiched between the mounting member 6 and the rotating seat 4, and thus connected to the rotating seat 4. The pull rope 5 is connected to the driving member 7, so that the rotating seat 4 is pulled to rotate relative to the base body 1 around the first direction under the drive of the driving member 7.

[0070] like Figure 1 As shown, the upper end of the rotating seat 4 protrudes upward from the top surface of the base body 1, and the mounting member 6 is provided at the upper end of the rotating seat 4. The pull rope 5 can be clamped between the mounting member 6 and the rotating seat 4, or can be directly fixedly connected to the mounting member 6, preferably clamped between the mounting member 6 and the rotating seat 4, so that the pull rope 5 is connected to the rotating seat 4. The pull rope 5 is also connected to the driving member 7, and the driving member 7 rotates or moves linearly to pull the pull rope 5, and pulls the rotating seat 4 to rotate around the vertical direction through the pull rope 5, thereby driving the magnet 2 to rotate around the vertical direction, so that the magnet 2 switches between the open position and the closed position.

[0071] Preferably, the mounting member 6 is fixedly connected to the rotating seat 4 by a connecting member such as a screw, and the pull rope 5 is clamped between the mounting member 6 and the rotating seat 4 so that the pull rope 5 can drive the rotating seat 4 to rotate, and the pull rope 5 and the rotating seat 4 will not slide relative to each other.

[0072] Preferably, the pull rope 5 is a steel cable so that the length of the pull rope 5 does not change. In other words, the length of the pull rope 5 is constant.

[0073] In some embodiments, the rotating seat 4 and the magnet 2 are connected in a one-to-one correspondence, the outer periphery of each magnet 2 is provided with a corresponding magnetic conductor 3 and a corresponding non-magnetic conductor, and the multiple rotating seats 4 are arranged in an annular interval on the base body 1, and the pull rope 5 is arranged in an annular shape and connected to the driving member 7. The driving member 7 is provided on the base body 1, and each rotating seat 4 is provided with a mounting member 6, so that the pull rope 5 is connected to the multiple rotating seats 4 in sequence, so that the driving member 7 can drive the multiple rotating seats 4 to rotate at the same time. Or the driving member 7 is provided on one of the rotating seats 4, and the remaining rotating seats 4 are provided with mounting members 6, so that the pull rope 5 is connected to the remaining rotating seats 4 in sequence, so that the driving member 7 can drive the multiple rotating seats 4 to rotate at the same time.

[0074] like Figure 1 and Figure 2 As shown, the base body 1 is provided with a plurality of rotating seats 4, preferably but not limited to three, the three rotating seats 4 are arranged in a ring-shaped interval, preferably but not limited to a triangular ring-shaped interval arrangement, and each corner of the triangular ring is provided with a corresponding rotating seat 4. The lower end of each rotating seat 4 is provided with a corresponding magnet 2, and the outer periphery of each magnet 2 is provided with a corresponding alternating arrangement of magnetic conductive bodies 3 and non-magnetic conductive bodies.

[0075] The pull rope 5 extends in a ring shape, preferably but not limited to a triangular ring shape, and a corresponding mounting member 6 is provided at the upper end of each rotating seat 4. Each rotating seat 4 and the mounting member 6 provided on the rotating seat 4 are clamped with the pull rope 5, and are clamped in sequence along the extension direction of the pull rope 5, so that the pull rope 5 connects the three rotating seats 4 in sequence.

[0076] The driving member 7 is arranged on the base body 1, and the driving member 7 is located on the extension track of the pull rope 5 and is connected to the pull rope 5. The driving member 7 is preferably, but not limited to, arranged between two of the rotating seats 4. The driving member 7 is used to drive the pull rope 5 to move along the extension direction of the pull rope 5, so as to simultaneously drive the three rotating seats 4 to rotate, thereby simultaneously driving the three magnets 2 to switch between the open position and the closed position, so as to facilitate the use and operation, and make the magnetic base have higher stability when it is adsorbed and fixed on the work surface. Preferably, the three magnets 2 are simultaneously located in the open position or simultaneously located in the closed position.

[0077] The driving member 7 can drive the pull rope 5 to always move in the same direction along the extension direction of its ring shape, for example, to move clockwise. At this time, the magnet 2 also always rotates in the same direction under the drive, and the magnet 2 switches every 90° rotation. The driving member 7 can also drive the pull rope 5 to move forward and reversely along the extension direction of its ring shape. At this time, the magnet 2 can also rotate forward and reversely under the drive. Preferably, the magnet 2 rotates forward 90° to switch to the open position, and rotates reversely 90° to switch to the closed position. Preferably, the driving member 7 drives the pull rope 5 to move forward and reversely. In other words, the driving member 7 drives the pull rope 5 to move back and forth.

[0078] It can be understood that the driving member is not limited to being disposed on the base body. In other embodiments, the driving member is disposed on one of the three rotating seats, and the pull rope extends in a ring shape, preferably but not limited to a triangular ring shape. The pull rope connects the driving member and the remaining two rotating seats except the rotating seat with the driving member. The driving member directly drives the rotating seat with the driving member to rotate, and at the same time pulls the pull rope to move along the extension direction of the pull rope, and drives the remaining two rotating seats to actively move, thereby driving the three rotating seats to rotate.

[0079] In some embodiments, an installation groove 41 is provided on the outer circumferential surface of the rotating seat 4, and the installation groove 41 extends along the circumference of the rotating seat 4 for embedding the pull rope 5. The mounting member 6 extends into the installation groove 41 to clamp the pull rope 5 between the mounting member 6 and the bottom surface of the groove 41.

[0080] like Figure 1As shown, the outer circumferential surface of the rotating seat 4 is provided with a mounting groove 41, and the mounting groove 41 extends along the circumference of the rotating seat 4. The mounting groove 41 can extend a distance along the circumference of the rotating seat 4, in other words, the mounting groove 41 can be arc-shaped. The mounting groove 41 can also extend one circle along the circumference of the rotating seat 4, in other words, the mounting groove 41 can also be annular. Preferably, the mounting groove 41 is annular. Part of the pull rope 5 fits in the mounting groove 41.

[0081] The mounting member 6 has a connected mounting portion and an extension portion. The mounting portion is arranged on the top surface of the rotating seat 4, and the extension portion is arranged at one end of the mounting portion and extends downward from the mounting portion. A channel is provided on the upper end groove wall surface of the mounting groove 41. The mounting portion extends into the mounting groove 41 through the channel and clamps part of the pull rope 5 between the mounting member 6 and the groove bottom surface of the mounting groove 41.

[0082] The mounting groove 41 guides and limits the pull rope 5 , preventing the pull rope 5 from being misplaced and knotted when moving under the drive of the driving member 7 , thereby ensuring that the rotating seat 4 can rotate smoothly and accurately under the drive of the pull rope 5 .

[0083] Preferably, the mounting groove 41 is annular, and the pull rope 5 is wound around the rotating seat 4 along the mounting groove 41 for at least one circle. When the mounting member 6 is located in the two overlapping sections formed by the winding of the pull rope 5, the mounting member 6 and the rotating seat 4 clamp one section of the pull rope 5. When the pull rope 5 pulls the rotating seat 4 to rotate, the part of the pull rope 5 wound on the rotating seat 4 detaches from the mounting groove 41 and moves toward the downstream direction of the rotating seat 4, and the part of the pull rope 5 located upstream of the rotating seat 4 and adjacent to the rotating seat 4 is wound in the mounting groove 41, thereby ensuring that the pull rope 5 drives the rotating seat 4 to rotate a certain angle, so that the rotating seat 4 drives the connected magnet 2 to rotate between the open position and the closed position.

[0084] In some embodiments, the driving member 7 is a rotating handle, which includes a connected rotating shaft 71 and a gripping portion 72. The rotating shaft 71 is arranged along a first direction and is arranged on the base body 1 or on one of the rotating seats 4.

[0085] like Figure 2 and Figure 3 As shown, the driving member 7 is a rotating handle, which is disposed on the base body 1 or on one of the rotating seats 4 and can rotate in a vertical direction relative to the base body 1, thereby driving the connected pull rope 5 to move. The rotating handle is preferably disposed on the base body 1.

[0086] The rotating handle includes a connected rotating shaft 71 and a gripping portion 72. The rotating shaft 71 is arranged on the base body 1 or on one of the rotating seats 4. Preferably, the rotating shaft 71 is arranged on the base body 1 and can rotate in a vertical direction relative to the base body 1. The rotating shaft 71 extends in the vertical direction, and a gripping portion 72 extending in the horizontal direction is provided at the top. The gripping portion 72 is used for the user to grip and thus rotate the rotating handle.

[0087] The outer circumferential surface of the rotating shaft 71 is provided with at least two connecting holes 73, preferably but not limited to two, the two connecting holes 73 are located at the same position in the circumferential direction of the rotating shaft 71, and are arranged in sequence along the axial direction of the rotating shaft 71, preferably arranged at intervals along the axial direction of the rotating shaft 71, one end of the pull rope 5 is arranged in one of the connecting holes 73, and the other end of the pull rope 5 is arranged in another connecting hole 73, so that the pull rope 5 connects the rotating handle and the three rotating seats 4, so that the rotating handle can drive the three rotating seats 4 to rotate simultaneously through the pull rope 5.

[0088] Preferably, at least one end of the pull cord 5 is wound around the outer circumference of the rotating shaft 71 for at least one circle. In other words, both ends of the pull cord 5 are wound around the outer circumference of the rotating shaft 71 for at least one circle, or one end of the pull cord 5 is wound around the outer circumference of the rotating shaft 71 for at least one circle. When the user turns the rotating handle, the part of one end of the pull cord 5 wound around the outer circumference of the rotating shaft 71 is released and moves away from the rotating shaft 71, and the other end of the pull cord 5 drives the pull cord 5 to wind around the outer circumference of the rotating shaft 71, so that the rotating shaft 71 can drive the pull cord 5 to move a certain distance along the extension direction of the pull cord 5, thereby ensuring that the pull cord 5 can drive the rotating seat 4 to rotate a certain angle, so that the rotating seat 4 drives the connected magnet 2 to rotate between the open position and the closed position.

[0089] Preferably, by the positive rotation of the rotating shaft 71 (such as Figure 2 Clockwise as shown) and reverse (as shown Figure 2 The pull rope 5 is driven to move forward and reversely along the extension direction of the pull rope 5 (counterclockwise as shown), thereby driving the three magnets 2 to switch between the open position and the closed position at the same time, and after switching, they are in the open position or in the closed position at the same time.

[0090] It should be noted that the rotation angle of the handle is not limited to 90°. The rotation angle is related to the arrangement position and quantity of the magnetic conductors 3 and the non-magnetic conductors, and is also related to the operator's usage habits.

[0091] In some embodiments, the magnetic base of the embodiment of the present invention further includes a base cover 8 and an inspection cover 9. Figure 4As shown, the shape of the base cover 8 is preferably consistent with the base body 1. The base cover 8 is detachably connected to the base body 1 so as to cover the base body 1. The upper end of the magnetic conductor 3, the upper end of the rotating seat 4, the mounting member 6 and the pull rope 5 are all located in the space between the base body 1 and the base cover 8. When the upper end of the non-magnetic conductor is inserted into the base body 1, the upper end of the non-magnetic conductor is also located in the space between the base body 1 and the base cover 8.

[0092] The base cover 8 is provided with a plurality of inspection holes, which penetrate the base cover 8 in the vertical direction. The plurality of inspection holes are arranged one by one corresponding to the plurality of rotating seats 4. The hole area of ​​the inspection holes accommodates the corresponding rotating seats 4, mounting parts 6 and magnets 3. When the upper end of the non-magnetic body is passed through the base body 1, the area of ​​the inspection holes also accommodates the non-magnetic body, so that the corresponding rotating seats 4, mounting parts 6, magnets 3 and non-magnetic bodies can be observed, maintained, inspected and disassembled through the inspection holes.

[0093] There are multiple inspection covers 9 arranged one by one corresponding to the inspection holes, and the inspection covers 9 are detachably connected to the base cover 8, the base body 1 or the corresponding magnetic conductor 3 to close and open the corresponding inspection holes.

[0094] The rotating shaft 71 passes through the base cover 8, and the upper end of the rotating shaft 71 and the gripping portion 72 are located above the base cover 8. In order to facilitate the user to rotate the gripping portion 72 to the specified position, the base cover 8 is provided with markings corresponding to the open position and the closed position, such as "open position" and "closed position", "open" and "close", "OFF" and "ON", etc.
