A metal cover is attached to the inner ring surface of the shell, and a plurality of silicon steel sheets are fixed to the inner ring, which can effectively prevent the magnetic field from leaking to the outside of the shell and affecting various sensors. In addition, the silicon steel block fixed inside the coil also has the function of increasing the magnetic field strength, so that the magnetic field can obtain greater adsorption force without leakage. A rubber pad is attached to the front end of the coil, and the rubber pad is located between the shell at the front end of the magnet and the outer ring cylinder. When in use, the rubber pad has a certain protective effect on the coil. However, the patent still has the following problems in actual use:

[0004] Although the coil support structure of this electromagnetic clutch has a metal cover attached to the inner ring surface of the shell and multiple silicon steel sheets are fixed to the inner ring, which can effectively prevent the magnetic field from leaking to the outside of the shell and affecting various sensors, when the electromagnetic coil fails, it is not convenient to disassemble and replace the coil, thereby reducing work efficiency.

[0005] A coil support structure for an electromagnetic clutch is proposed to solve the above-mentioned problems. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coil support structure for an electromagnetic clutch, comprising a clamping mechanism, and a coil support top plate installed on one side of the clamping mechanism;

[0008] Also includes:

[0009] The clamping mechanism includes a coil support base, and a plurality of grooves are provided inside the coil support base. The number of the grooves is four, and the grooves are evenly distributed inside one side of the coil support base.

[0010] Wherein, the coil support base is symmetrically provided with first limiting grooves on the upper and lower sides close to the groove;

[0011] Among them, one end of the first limiting groove is fixedly connected to a spring, one end of the spring is fixedly connected to a trapezoidal block, and the outer side of the trapezoidal block is slidably connected to the first limiting groove.

[0012] Preferably, a spherical bump is disposed inside the groove, and an annular groove is formed inside one end of the spherical bump.

[0013] Preferably, a circular ring is fittedly connected to the interior of the annular groove, and a cylinder is slidably connected to the inner wall of the circular ring.

[0014] Preferably, one end of the cylinder is fixedly connected to the spherical bump, and one end of the cylinder away from the spherical bump is fixedly connected to a push rod.

[0015] Preferably, the outer side of the push rod away from the cylinder end is fixedly connected to a limiting block, and the outer side of the push rod is slidably connected to the top plate of the coil support.

[0016] Preferably, the side of the coil support top plate close to the cylinder is closely connected to the coil support base.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the coil support structure for the electromagnetic clutch can quickly remove the coil support top plate from the coil support base by setting a snap-fit ​​mechanism, so as to facilitate the replacement of the coil. The specific contents are as follows:

[0019] By setting up a locking mechanism, the coil support top plate can be quickly removed from the coil support base, which is convenient for replacing the coil. The trapezoidal block is used to limit the spherical protrusion to prevent the coil support top plate from falling off from the coil support base. The spherical protrusion is driven to move in the groove by pressing the push rod inward, thereby driving the ring to slide on the surface of the cylinder. At the same time, the trapezoidal block moves along the outer side of the ring in the first limiting groove, thereby changing the protruding position of the trapezoidal block. When the ring coincides with the spherical protrusion, the spherical protrusion can be taken out of the groove, thereby releasing the limitation of the trapezoidal block on the coil support top plate, and realizing the disassembly of the coil support top plate. By setting up the limiting block, the push rod can be prevented from falling from the coil support top plate. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4The utility model provides a technical solution: a coil support structure for an electromagnetic clutch, comprising a clamping mechanism 1, and a coil support top plate 112 installed on one side of the clamping mechanism 1; the clamping mechanism 1 comprises a coil support base 101, a plurality of grooves 102 are provided inside the coil support base 101, the number of the grooves 102 is four, and the grooves 102 are evenly distributed inside one side of the coil support base 101, and a coil is wound around the outside of the coil support base 101;

[0027] The coil support base 101 is symmetrically provided with first limiting grooves 103 on both sides of the upper and lower sides near the groove 102; a spring 104 is fixedly connected to one end of the first limiting groove 103, and a trapezoidal block 105 is fixedly connected to one end of the spring 104. The outer side of the trapezoidal block 105 is slidably connected to the first limiting groove 103. By providing the spring 104, the trapezoidal block 105 can always extend out of the first limiting groove 103 and limit the spherical protrusion 106 without being acted upon by external force.

[0028] A spherical bump 106 is provided inside the groove 102, and an annular groove 107 is provided inside one end of the spherical bump 106. A circular ring 108 is fitted and connected inside the annular groove 107. A cylindrical cylinder 109 is slidably connected to the inner wall of the circular ring 108. The circular ring 108 can be driven to move on the surface of the cylindrical cylinder 109 through the trapezoidal block 105.

[0029] One end of the cylinder 109 is fixedly connected to the spherical bump 106, and one end of the cylinder 109 away from the spherical bump 106 is fixedly connected to a push rod 110. The outer side of the push rod 110 away from the end of the cylinder 109 is fixedly connected to a limiting block 111. The outer side of the push rod 110 is slidably connected to the top plate 112 of the coil support. By setting the limiting block 111, the push rod 110 is prevented from falling from the top plate 112 of the coil support.

[0030] The side of the coil support top plate 112 close to the cylinder 109 is fitted and connected to the coil support base 101. A second limiting groove 113 is provided on the outer side of the coil support top plate 112 close to the push rod 110.

[0031] Working principle: Before using this electromagnetic clutch coil support structure, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 4 As shown, first, the push rod 110 is pressed inward to drive the spherical protrusion 106 to move in the groove 102, thereby driving the ring 108 to slide on the surface of the cylinder 109, and at the same time, the trapezoidal block 105 moves along the outer side of the ring 108 in the first limiting groove 103, so that the trapezoidal block 105 moves to the other side of the ring 108;

[0032] Secondly, pull the coil support top plate 112 outward and drive the spherical protrusion 106 to move outward in the groove 102, and the trapezoidal block 105 pushes the ring 108 to move in the direction of the spherical protrusion 106. At the same time, the trapezoidal block 105 moves in the first limiting groove 103 along the outer side of the ring 108. When the ring 108 coincides with the spherical protrusion 106, the limitation of the spherical protrusion 106 by the trapezoidal block 105 can be released, and the spherical protrusion 106 can be taken out of the groove 102, so that the limitation of the coil support top plate 112 by the trapezoidal block 105 can be released, and the coil support top plate 112 can be disassembled, which is convenient for the replacement of the coil.
