The present invention relates to a magnet device for adsorption that is used to move various objects made of iron by magnetic force.

More specifically, this is a design related to Utility Model Registration Nos. 795778 and 82115, which the applicant has previously registered.

The above-described prior application registration design requires a plurality of front and rear stimulating members connected in parallel and a rotor case sandwiched between the bottom and left and right cover plates at a predetermined interval on both sides of the front and rear magnetic pole members. If the groove is formed and the left and right cover plates and the bottom plate which serve this groove are formed with holes or cutout grooves, bolts or welds are fixed. Thus, when a groove is drilled in the front and rear pole members themselves, this groove may cause leakage magnetic force. In addition, the vortex phenomenon occurs in the gyro, there is a drawback to weaken the dispersion of the adsorbed magnetic force.

Therefore, the most preferable is that the front and rear pole members, the left and right cover plates and the bottom plate are ideally molded into a single body such as a cast molding, but the front and rear pole members should be a good magnetic material, and the shaft fitting plate and the bottom plate and the left and right cover plates are made of nonmagnetic material. Because of this, co-molding, like casting, has the problem.

The present invention is devised to solve the above problems, and the subject matter of the present invention is that the rotor case sandwiched between the front and rear pole members and the left and right cover plates coupled to the left and right sides of the front and rear pole members are similarly molded and integrally formed so as to have the same strength as before and after. The magnetic pole member itself does not have a hole or a groove, but instead, grooves are formed in the left and right cover plates and the bottom plate itself, thereby welding the groove portions, thereby enabling a function similar to that of a single casting.

This will be described in detail based on the drawings.

Between the left and right cover plates 3, which are nonmagnetic materials, the intermediate part becomes a nonmagnetic material 2, and the left and right parts are nonmagnetic material between the front and rear magnetic pole members 1, 1 ', 1', 1 'and 1' '. Fixed permanent magnets 13 (13 ') are inserted into a vacancy formed by fitting the rotor case 11 (11') made of an adult, and left and right cover plates 3 and bottom plates 12 on the left and right sides and the bottom of the vacancy. In the integrally coupled to the upper and lower ends of the left and right cover plate (3) to form a plurality of "c" type notch groove (5) at regular intervals, the notch groove (5) is the front and rear pole member (1) (1 ') ( 1 ″) (1 '′ ′) to be welded to the reinforcement weld section 6, and the reinforcing weld section is welded to the right and left ends of the bottom plate 12 fitted on the bottom by inclining the surface 12'. 6 '' is formed.

Reference numeral 14 denotes a handle, 15 a fixture, and 16 a hook.

Figure 3 is a separate embodiment of the present invention by arranging the arc-shaped notch groove (5 ') in the upper and lower ends of the left and right cover plate 3, the front and rear magnetic pole members (1) (1') (1 ") (1 '' ') When the left and right cover plates 3 are welded jointly, the reinforcing welding portion 6 'is formed by the arc-shaped notch 5', and FIG. 5 divides the left and right cover plates 3 of FIG. It is fixed by the welding part 6 as the equal cover plate 3 ', and FIG. 6 divides the left and right cover plates 3 of FIG. 5 into 2 equal parts 3 ", and welds it to the welding part 6'. 7 and 8 show the support piece 7 between the left and right ends of the front and rear magnetic pole members 1, 1 ', 1 ″, 1' ′ 'as another separate embodiment of the present invention. Thus, the inclined surface 7 'formed at both ends of the support piece 7 is welded to form a welded portion 6 ″.

The present invention constructed as described above is a bar magnet device for adsorption, which is mainly used for adsorption and movement of various objects made of magnetic material. By operating the handle 14, the permanent magnets 10 and 10 'in the rotor 9 are rotated. The poles of the permanent magnet pieces 13 and 13 'inserted in the vacancy formed by the electronic case 11 (11') and the left and right cover plates 3 and the cover plate 4 and the bottom plate 1 are integral with each other. Is turned ON when the object is adsorbed, and when the poles of the rotor permanent magnets 10 (10 ') and the permanent magnets 13 (13') in the vacancy are opposite to each other, It is well known to release the adsorbed object, the present invention is the front and rear magnetic pole member (1) (1 ') (1 ") (1' '') and the left and right cover plates (3) and the front and rear that generate magnetic force for adsorption. The rotor case 11 sandwiched between the magnetic pole members 1, 1 ', and the front and rear magnetic pole members 1, 1', 1 " ′) It is a through hole or a groove in itself Instead of forming a groove, grooves 5, 5 'and inclined surfaces 7, 12' are formed in the left and right cover plates 3, 3 ', 3 " and the bottom plate 12 itself. 5) By welding the areas of 5 'and 5' and 7 'and 12', the reinforcing welds 6, 6 ', 6 "and 6' 'are not exposed to the outside and welded. Since it is relatively thick, even when the device body is severely impacted from the outside, it is not broken or deformed, so that the generation efficiency of the adsorption magnetic force can be further improved, which is very practical.
