Description

Technical Field

[0001] The utility model relates to the technical field of electromagnets, and more specifically to an electromagnet with a protection frame. Background Art

[0002] An electromagnet is a device that uses electric current to pass through a coil wound around an iron core to generate a magnetic field. It is mainly composed of an iron core, a coil, and a power source. When current passes through the coil, a magnetic field is generated around the iron core, making the electromagnet magnetic.

[0003] When the electromagnet is hit, the structure of the electromagnet may be damaged, such as the core shifting, coil deformation, etc., which will affect the normal working performance of the electromagnet, weaken its magnetic force or make it unstable. Secondly, the impact may cause the coil to be broken or short-circuited. If the coil is broken, the electromagnet may completely lose its magnetism; if a short circuit occurs, it may cause abnormal current, heat and even cause safety problems, such as fire.

[0004] Therefore, a metal protective frame is specially designed to surround the electromagnet to prevent direct collision and damage to the electromagnet by external objects and protect its structural integrity.

[0005] Existing electromagnets usually use a metal frame to surround the electromagnet to protect it from impact, but the protective frame of this structure is relatively bulky. When it is hit, the protective frame itself will vibrate and still produce impact force on the electromagnet, resulting in poor impact protection for the electromagnet. In view of this, we propose an electromagnet with a protective frame. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art, meet practical needs, and provide an electromagnet with a protective frame to solve the current technical problem of poor impact protection of the electromagnet.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: an electromagnet with a protective frame, comprising a bottom plate, a plurality of fixed plates connected to the top surface of the bottom plate, a rubber pad connected to the side wall of the fixed plate, an electromagnet body provided on the side wall of the rubber pad, a connecting wire provided on the side wall of the electromagnet body, a plurality of springs connected to the other side wall of the fixed plate, a protective plate connected to the end of the spring, and a top cover connected to the top surface of the fixed plate.

[0008] Preferably, a groove matching the bottom of the electromagnet body is formed on the top surface of the bottom plate, and a plurality of holes are formed on the bottom plate from top to bottom.

[0009] Preferably, the fixing plate is an arc-shaped plate, a sliding groove is provided on a side wall of the fixing plate, a filter screen is arranged in the sliding groove, and the filter screen is slidably connected to the fixing plate through the sliding groove.

[0010] Preferably, the plurality of fixed plates are arranged in a circular array, the plurality of protective plates are arranged on the outer sides of the plurality of fixed plates and arranged in a circular array, the side walls of the protective plates are provided with a plurality of strip holes, and the side walls of the strip holes are aligned with the side walls of the filter in the horizontal direction.

[0011] Preferably, the rubber pad is an arc-shaped plate structure, and the arc-shaped surface of the side wall of the rubber pad fits with the arc-shaped surface of the circumferential outer wall of the electromagnet body.

[0012] Preferably, a wire groove is provided at the bottom of the protective plate, and a connecting wire is arranged in the wire groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model uses the protective plate to be acted upon by the elastic force of the spring, which repels the impact force received, thereby offsetting most of the impact force, and a small part of the impact force is borne by the fixed plate. The rubber pad on the side wall of the fixed plate can reduce the shock and prevent the side wall of the electromagnet body from being subjected to the impact force, thereby achieving the effect of protecting the electromagnet body during impact and solving the problem of poor impact protection of the electromagnet.

[0015] 2. The utility model also forms a multi-layer protection design by combining a plurality of protective plates arranged in a circular array with a plurality of fixing plates arranged in a circular array, and a plurality of rubber pads that match the shape of the side walls of the electromagnet body to enclose, fix and protect the electromagnet body, which can reduce the weight of the protective frame and at the same time, has a good protection effect on the electromagnet from impact, further solving the problem of poor impact protection of the electromagnet.

[0026] In the embodiment of the utility model, when the device is hit, the outermost protective plate 301 is hit first. The protective plate 301 is subjected to the elastic force of the spring 304, which repels the impact force and can offset most of the impact force. A small part of the impact force is borne by the fixed plate 401. The rubber pad 402 on the side wall of the fixed plate 401 can reduce the shock and prevent the side wall of the electromagnet body 101 from being subjected to the impact force. By adopting a multi-layer protection design, the weight of the protection frame can be reduced and at the same time, the protection effect of the electromagnet being subjected to impact is good.

[0027] Specifically, the top surface of the bottom plate 201 is provided with a groove 202 that fits with the bottom of the electromagnet body 101 , and the bottom plate 201 is provided with a plurality of holes 203 from top to bottom, which are conducive to air circulation and dissipate the heat generated by the electromagnet body 101 .

[0028] Furthermore, the fixed plate 401 is an arc-shaped plate, and a slide groove 404 is opened on the side wall of the fixed plate 401. A filter 403 is arranged in the slide groove 404. The filter 403 is slidably connected to the fixed plate 401 through the slide groove 404. The filter 403 can not only play a blocking role and filter most impurities from entering the interior of the device, but also can provide better air circulation.

[0029] It is worth noting that multiple fixed plates 401 are arranged in a circular array, and multiple protective plates 301 are arranged on the outer sides of the multiple fixed plates 401 in a circular array. Multiple strip holes 302 are opened on the side walls of the protective plates 301, and the side walls of the strip holes 302 are aligned with the side walls of the filter 403 in the horizontal direction. The strip holes 302 are conducive to air circulation between the structures of this device.

[0030] It is worth noting that the rubber pad 402 is an arc-shaped plate structure. The arc-shaped surface of the side wall of the rubber pad 402 matches the arc-shaped surface of the circumferential outer wall of the electromagnet body 101, which can clamp and fix the electromagnet body 101 and at the same time more appropriately protect the electromagnet body 101 from being damaged by impact.

[0031] It is worth mentioning that a wire groove 303 is provided at the bottom of the protective plate 301 , and a connecting wire 102 is arranged in the wire groove 303 . The wire groove 303 facilitates the connecting wire 102 to connect the external power supply with the electromagnet body 101 .
