For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.
[0026] In one embodiment of the present invention, Figures 1 to 3 As shown, a locker switch electromagnet is provided, including a mounting seat 10, a core assembly and a connector 30. The core assembly includes a moving core 21, a fixed core 22, a bobbin 23 and a coil 24. The bobbin 23 is arranged in the mounting seat 10, and a mounting cavity 231 is provided in the bobbin 23. The coil 24 is arranged on the outside of the bobbin 23, and a sound insulation layer 25 for sound insulation is provided on the outside of the coil 24. The fixed core 22 is fixedly connected in the mounting cavity 231. The moving core 21 is slidably connected in the mounting cavity 231 and is located above the fixed core 22. A buffer component for buffering is provided between the moving core 21 and the fixed core 22. A fixed cover 13 is provided between the moving core 21 and the mounting seat 10, and sound insulation cotton 14 is provided in the fixed cover 13. The connector 30 is provided below the mounting seat 10 and connected to the moving core 21.
[0027] In this embodiment, the sound insulation layer 25 is made of sound insulation material, such as a sound insulation board, sound insulation cotton 14, etc. The sound insulation layer 25 absorbs the noise generated by the electromagnet, thereby reducing the noise of the electromagnet and facilitating better use by users.
[0028] When the moving iron core 21 approaches the fixed iron core 22, the buffer component is used to buffer the moving iron core 21 and the fixed iron core 22, thereby reducing the impact force when the two are close to each other and reducing the noise of the electromagnet. At the same time, the sound insulation layer 25 and the sound insulation cotton 14 weaken the noise generated when the electromagnet is working, thereby greatly reducing the noise of the electromagnet and facilitating better use by users.
[0029] Preferably, the buffer component includes a first buffer block 261 and a second buffer block 262. The first buffer block 261 is arranged on the moving iron core 21. The second buffer block 262 is arranged on the fixed iron core 22. The moving iron core 21 is close to the fixed iron core 22, and the first buffer block 261 and the second buffer block 262 are in conflict with each other. In this embodiment, the first buffer block 261 and the second buffer block 262 are both rubber pads, and buffer pads can also be made of other materials with buffering effects. The first buffer block 261 and the second buffer block 262 buffer the impact force generated when the moving iron core 21 collides with the fixed iron core 22, thereby reducing the noise generated when the two collide.
[0030] Furthermore, the moving iron core 21 has a protrusion 211 extending outward at one end close to the fixed iron core 22, and the protrusion 211 has a conical structure. The first buffer block 261 is located on the protrusion 211. A spring 212 is provided on the protrusion 211, and the spring 212 is provided between the moving iron core 21 and the fixed iron core 22. By providing the spring 212, a buffering effect is played on the collision between the moving iron core 21 and the fixed iron core 22, and the noise generated when the collision between the two is further reduced.
[0031] Furthermore, one end of the fixed iron core 22 is provided with a movable groove 221 corresponding to the protrusion 211. The second buffer block 262 is located in the movable groove 221. The collision generated when the protrusion 211 contacts the movable groove 221 is buffered by the spring 212, the first buffer block 261 and the second buffer block 262, which greatly reduces the noise generated when the two collide, and facilitates better use by users.
[0032] Preferably, a guide rod 27 is connected to one end of the moving iron core 21 close to the fixed iron core 22. One end of the guide rod 27 is fixedly connected to the moving iron core 21, and the other end is connected to the connecting piece 30. The connecting piece 30 includes a horizontal portion 31 and a vertical portion 32. The horizontal portion 31 is connected to the vertical portion 32, and the horizontal portion 31 and the vertical portion 32 are arranged at 90 degrees. The horizontal portion 31 is connected to the guide rod 27. When the moving iron core 21 is close to the fixed iron core 22, the moving iron core 21 drives the guide rod 27 to move outward, and then drives the connecting piece 30 to move outward, so that the vertical portion 32 on the connecting rod is locked with the cabinet door on the locker, thereby achieving the locking of the cabinet door.
[0033] Preferably, the core assembly further includes a yoke 28 and a protective cover 29. The yoke 28 is disposed between the mounting seat 10 and the bobbin 23. The protective cover 29 is disposed on the sound insulation layer 25 to protect the coil 24. By providing the yoke 28, the magnetic lines of force generated by the electromagnetic coil 24 are enclosed inside, thereby improving the efficiency of the electromagnet; by providing the protective cover 29, the coil 24 can be protected, thereby improving the service life of the electromagnet.
[0034] Furthermore, a plurality of rubber blocks 11 for buffering are arranged between the mounting seat 10 and the yoke 28. The plurality of rubber blocks 11 are evenly distributed on the mounting seat 10. The rubber blocks 11 are arranged to protect the core assembly, prevent the core assembly from directly colliding with the mounting seat 10, and improve the service life of the electromagnet.
[0035] Furthermore, both sides of the mounting base 10 are provided with connecting parts 12 extending outward, and the connecting parts 12 are provided with two sets of fixing holes 121. The connecting parts 12 are connected to the locker to facilitate the installation of the electromagnet.
[0036] By providing a sound insulation layer 25, sound insulation cotton 14 and a buffer component, when the moving iron core 21 approaches the fixed iron core 22, the buffer component buffers the moving iron core 21 and the fixed iron core 22, reduces the impact force when the two approach each other, reduces the noise of the electromagnet, and at the same time, the sound insulation layer 25 and the sound insulation cotton 14 weaken the noise generated when the electromagnet is working, thereby greatly reducing the noise of the electromagnet, which is convenient for users to use better.
[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
