[0002] An electromagnet is a device that generates electromagnetic force when powered on; a conductive winding matching its power is wound outside an iron core. This current-carrying coil has magnetism like a magnet, and it is also called an electromagnet. By energizing the coil, a magnetic force is generated on the fixed iron core to drive the moving iron core to move. Electromagnets are widely used in products such as televisions, tape recorders, electromagnetic cranes, electric fans, electric bells, electromagnetic relays, and electromagnetic automatic doors.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figure 1-7 shown, the present invention provides an electromagnet that is easy to fix, mainly composed of an electromagnet body 2 and a housing 1 for installing the electromagnet body 2. And through the optimization of the internal structure, the fixing property of the electromagnet body 2 installed in the housing 1 is improved, and it is convenient for the electromagnet body 2 to be assembled in the housing 1.

[0026] The housing 1 is composed of an outer shell 101 and a sealing cover 102. Among them, one end of the outer shell 101 is open, and the sealing cover 102 is arranged at the opening of the outer shell 101 to be connected and sealed. At this time, a space for placing and fixing the electromagnet body 2 is formed inside the housing 1. When the outer shell 101 and the sealing cover 102 are connected, the two are fixed by an insertion connection method, and a concave-convex surface 9 is provided at the connection position to prevent falling off after connection. The concave-convex surface 9 is composed of a convex position provided at one end of the outer shell 101 and a concave position provided at one end of the sealing cover 102. When docking, the convex position slides into the concave position for fixation. At the same time, screws and other methods can also be added to strengthen the fixation.

[0027] The middle part of the end of the outer shell 101 far away from the opening is hollowed out, and a panel 3 covering the hollowed-out part is arranged inside. After being combined with the electromagnet body 2, the panel 3 is mainly used to transmit magnetic force. When the panel 3 is arranged inside the outer shell 101 to cover the hollowed-out end, the panel 3 is fixed to the outer shell 101 by four clamping posts 11 on the side in contact with the outer shell 101, preventing the panel from moving randomly at the hollowed-out part of the outer shell 101. At the same time, a convex part 10 with a convex shape matching the hollowed-out part is provided at one end of the panel 3 covering the hollowed-out part of the outer shell 101, which can further fix the position of the panel 3. After the convex convex part 10 is combined with the hollowed-out part of the outer shell 101, a structure with aligned surfaces is formed.

[0028] In order to better fix the position of the electromagnet body 2, a coaxially arranged card slot 4 is provided on the surface of the panel 3. One end of the electromagnet body 2 is arranged in the card slot 4 for fixation. At the same time, the sealing cover 102 is attached to the other end of the electromagnet body 2, and a snap ring 5 with a protrusion for snap connection with the electromagnet body 2 is provided. At this time, one end of the electromagnet body 2 is fixed by the card slot 4 and the other end is fixed by the snap ring 5. After both ends are fixed, there will be no movement phenomenon, and the entire assembly process is simple, facilitating the fixation process of the electromagnet body 2. To protect the surface of the electromagnet body 2 and improve the sealing performance, a silica gel layer 12 is also adhesively attached to the inner side of the snap ring 5 on the sealing cover 102, and this silica gel layer 12 contacts the surface of the electromagnet body 2 during assembly.

[0029] In addition, a first rubber ring 6, a second rubber ring 7, and multiple limiting insertion posts 8 are additionally provided inside the housing 101 to strengthen the fixation of the side surface of the electromagnet body 2 inside. During connection, the first rubber ring 6 closely adheres to the outer side of the electromagnet body 2, the second rubber ring 7 closely adheres to the inner wall of the housing 101, and the multiple limiting insertion posts 8 are inserted between the first rubber ring 6 and the second rubber ring 7 and squeeze the first rubber ring 6 and the second rubber ring 7 on both sides. When the limiting insertion posts 8 are distributed, they are annularly distributed with the center of the electromagnet body 2 as the base point. When the first rubber ring 6 and the second rubber ring 7 are squeezed by the limiting insertion posts 8, the electromagnet body 2 cannot move around after being fixed. Moreover, according to the squeezing amplitude of the limiting insertion posts 8 on the first rubber ring 6 and the second rubber ring 7, it can be applied to electromagnet bodies 2 of different specifications. When installing the electromagnet body 2 into the housing 1, an opening position can also be left to lead out the wire of the electromagnet body 2.

[0030] Compared with the traditional technology, when fixing the electromagnet body 2 inside the housing 1 in this technical solution, a card slot 4 and a snap ring 5 for restricting the movement of the electromagnet body 2 are respectively provided. At the same time, two rubber rings and squeezing limiting insertion posts 8 are added inside the housing 1 to further strengthen the fixation of the side surface of the electromagnet body 2, improve the stability of the electromagnet body 2, and facilitate assembly.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to encompass all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model, and any reference signs in the claims should not be regarded as limiting the claimed rights.
