Description

Technical Field

[0001] This utility model relates to the field of magnetic attraction equipment technology, specifically a conical magnetic beater. Background Technology

[0002] A conical magnetic swatter is a device primarily used to attract and collect scattered ferromagnetic objects. It typically employs a conical design to better accommodate metal objects of different shapes and sizes, improving operational flexibility and efficiency. The core component of the conical magnetic swatter is a magnet made of a strongly magnetic material, capable of generating a powerful magnetic field to attract and retain ferromagnetic materials. Conical magnetic swatters are widely used in manufacturing, warehousing and logistics, and waste recycling, such as in steel mills, auto repair shops, and transportation sorting scenarios.

[0003] In the existing technology, the inability to directly customize tapered coils leads to poor matching between the coil and the housing, resulting in unstable magnetic field effects. Furthermore, the coil and PCBA board are only fixed by a simple structure, which makes them prone to displacement during assembly or use, affecting performance.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing a conical magnetic paddle. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a conical magnetic snapper. First, by pre-setting the conical inner cavity contours of the upper and lower shells, the ordinary coil naturally completes secondary shaping during assembly through cavity constraints, achieving a fit with the shell without relying on a customized conical coil, thus solving the problem of poor coil-shell matching. Second, a triple fixing mechanism of "radial, axial, and lead wire clamping" is adopted: the positioning ring achieves radial limiting of the coil, the coil pressure plate forms axial pressing through the connecting column a, and the rotatable wire clamp adaptively clamps the extension section of the coil, comprehensively restricting the displacement of the coil during assembly and use. Compared with the simple fixing method of the prior art, this structure can effectively prevent the coil from shifting due to force or vibration, ensuring the stability of the magnetic snapper performance.

[0006] This utility model provides the following technical solution: a conical magnetic paddle, including a housing assembly;

[0007] The housing assembly consists of an upper shell and a lower shell; the inner wall of the upper shell is provided with several slots, and the inner wall of the lower shell is fixedly connected with several buckles, and both of them have steps on their opposite surfaces. The upper shell and the lower shell are initially connected by the slots and buckles and the steps are fitted together, and a special adhesive is applied to the opposite surfaces of the upper shell and the lower shell and cured to form a sealed connection.

[0008] The surfaces of the upper and lower shells are symmetrically provided with two central holes; a positioning ring is provided on the outer side of each central hole; a coil pressure plate is provided on the inner wall of the lower shell; the inner cavities of the upper and lower shells jointly accommodate the coil, and the coil is radially positioned by the positioning ring and axially fixed by the coil pressure plate.

[0009] The inner cavity of the lower shell is provided with a PCBA board;

[0010] The surfaces of the upper and lower shells are connected by a corrugated pipe.

[0011] As a preferred technical solution of this utility model, a connecting plate is fixedly connected to the inner wall of the lower shell, and multiple connecting shafts are rotatably connected to the surface of the connecting plate. A wire clamp is fixedly connected to the surface of each connecting shaft, and a through hole is opened at one end of the connecting plate.

[0012] As a preferred embodiment of this utility model, two connecting posts a are symmetrically fixed to the inner wall of the lower shell, and the coil pressure plate is detachably connected to the connecting posts a by screws.

[0013] As a preferred embodiment of this utility model, four connecting posts b are symmetrically fixed to the inner wall of the lower shell, and the PCBA board is detachably connected to the connecting posts b by screws.

[0014] As a preferred embodiment of this utility model, a button is embedded in both the inner cavities of the upper and lower shells, and the button is electrically connected to the PCBA board.

[0015] As a preferred embodiment of this utility model, the surface of the corrugated pipe is provided with anti-slip grooves, which are distributed in a ring array.

[0016] As a preferred technical solution of this utility model, the inner cavities of the upper and lower shells are tapered contours adapted to the secondary shaping of the coil, so that the coil naturally fits the inner cavity of the shell during assembly and forms a preset magnetic field shape.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the prior art, the inability to directly customize tapered coils leads to poor compatibility between the coil and the housing. This utility model solves the problem of poor coil-housing compatibility by pre-setting the tapered inner cavity contours of the upper and lower housings, allowing ordinary coils to naturally complete secondary shaping during assembly through cavity constraints. This eliminates the need for customized tapered coils to achieve a close fit with the housing.

[0019] 2. To address the shortcomings of existing technologies where coils are easily displaced due to simple structural fixation, this invention employs a triple fixing mechanism of "radial, axial, and lead wire clamping": a positioning ring achieves radial limiting of the coil, a coil pressure plate forms axial clamping through connecting post a, and a rotatable wire clamp provides adaptive clamping of the coil extension section, comprehensively restricting the displacement of the coil during assembly and use. Compared to the simple fixing methods of existing technologies, this structure can effectively prevent the coil from shifting due to force or vibration, ensuring the stability of the magnetic beat performance.

[0020] 3. During the potting process, epoxy resin fills the gaps around the coil evenly, forming an integrated structure with the shell and coil, further enhancing the fixing effect. This design not only prevents the coil from shifting due to the impact of the adhesive during the potting stage, but also prevents the coil from loosening during long-term use, solving the performance degradation problem caused by insecure fixing in the existing technology and ensuring the long-term stability of the magnetic field effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 As shown, the conical magnetic paddle includes a housing assembly;

[0028] The housing assembly consists of an upper shell 1 and a lower shell 101. The inner wall of the upper shell 1 is provided with several slots 102, and the inner wall of the lower shell 101 is fixedly connected with several buckles 103. The opposing surfaces of the two are provided with steps 104. The upper shell 1 and the lower shell 101 are initially connected by the slots 102 and the buckles 103, and the steps 104 are attached. A special adhesive is applied to the opposing surfaces of the upper shell 1 and the lower shell 101 and cured to form a sealed connection.

[0029] Two central holes 2 are symmetrically opened on the surfaces of the upper shell 1 and the lower shell 101; a positioning ring 201 is set on the outer side of each central hole 2; a coil pressure plate 202 is provided on the inner wall of the lower shell 101; the inner cavities of the upper shell 1 and the lower shell 101 jointly accommodate the coil 203, and the coil 203 is radially positioned by the positioning ring 201 and axially fixed by the coil pressure plate 202.

[0030] The inner cavity of the lower shell 101 is provided with a PCBA board 3;

[0031] The surfaces of the upper shell 1 and the lower shell 101 are connected together by a bellows 4;

[0032] A connecting plate 5 is fixedly connected to the inner wall of the lower shell 101. Multiple connecting shafts 501 are rotatably connected to the surface of the connecting plate 5. A wire clamp 502 is fixedly connected to the surface of each connecting shaft 501. A through hole 503 is opened through one end of the connecting plate 5.

[0033] Two connecting posts a6 are symmetrically fixed to the inner wall of the lower shell 101, and the coil pressure plate 202 is detachably connected to the connecting posts a6 by screws.

[0034] Four connecting posts b7 are symmetrically fixed to the inner wall of the lower shell 101, and the PCBA board 3 is detachably connected to the connecting posts b7 by screws.

[0035] The button 8 is embedded in the inner cavity of the upper shell 1 and the lower shell 101, and the button 8 is electrically connected to the PCBA board 3;

[0036] The surface of the bellows 4 is provided with anti-slip grooves, which are distributed in a ring array.

[0037] The inner cavities of the upper shell 1 and the lower shell 101 are shaped into conical profiles to accommodate the secondary shaping of the coil 203, so that the coil 203 naturally fits the inner cavity of the shell during assembly and forms a preset magnetic field shape.

[0038] Before the coil 203 is installed, the inner cavities of the upper shell 1 and the lower shell 101 are pre-designed as conical contours. This contour matches the secondary shaping requirements of the coil 203. During assembly, the coil 203 is first placed into the cavity of the lower shell 101. Due to the constraints of the cavity shape, the coil 203 initially fits against the inner wall, completing the pre-shaping and laying the foundation for the subsequent precise magnetic field shape.

[0039] After the central holes 2 symmetrically opened on the surfaces of the upper shell 1 and the lower shell 101 are aligned, the positioning ring 201 on its outer side cooperates with the central through hole of the coil 203 to form a radial limit, restricting the displacement of the coil 203 in the horizontal direction and ensuring that the axis of the coil 203 is consistent with the overall axis of the magnetic beater.

[0040] The connecting post a6 on the inner wall of the lower shell 101 is connected to the coil pressure plate 202 by screws. The coil pressure plate 202 presses the edge of the coil 203 to achieve axial pressing (limiting vertical displacement). Through the double constraint of the "positioning ring 201 (radial) and coil pressure plate 202 (axial)," the coil 203 is stably fixed in the inner cavity of the upper shell 1 and the lower shell 101.

[0041] The two extension sections of coil 203 are mounted and fixed using the following structure:

[0042] On the connecting plate 5 on the inner wall of the lower shell 101, the connecting shaft 501 can rotate freely, driving the wire clamp 502 to adjust the angle so that the wire clamp 502 can fit the direction of the coil extension section and tightly clamp the surface of the extension section to prevent it from loosening in subsequent processes.

[0043] The clamping force of the wire clamp 502 ensures that the coil extension section will not be displaced due to the impact of the glue or gravity when the epoxy resin is potted; at the same time, the through hole 503 of the connecting plate 5 provides a flow channel for the glue, so that the glue can evenly wrap the connection part between the extension section and the wire clamp 502, and further enhance the fixing effect after curing.

[0044] When the epoxy resin adhesive (75% component A + 25% component B) is injected into the inner cavity of the upper shell 1 and the lower shell 101:

[0045] Due to the multiple constraints of the positioning ring 201, the coil pressure plate 202, and the wire clamp 502, the coil 203 maintains its preset position.

[0046] The adhesive fills the gaps around the coil through the through hole 503. After curing, it forms an integrated structure of "coil, shell and potting compound", which completely fixes the coil 203 and the extension section, eliminates the risk of displacement during long-term use and ensures the stability of the magnetic field.

[0047] PCBA board 3 is fixed to the lower shell 101 by connecting post b7 and screws to ensure circuit stability;

[0048] Button 8 is embedded in the inner cavity of the upper shell 1 and the lower shell 101, and is electrically connected to PCBA board 3 to realize function triggering (such as switch, mode switching);

[0049] The bellows 4 is connected to the surfaces of the upper shell 1 and the lower shell 101. The annular array of anti-slip grooves on its surface increases friction, strengthens the connection stability with the hand or external parts, and improves the comfort of operation and grip. At the same time, after the bellows 4 is connected, the user cannot remove the bellows 4 without damaging the magnetic paddle.
