Abstract
The utility model discloses a magnetic-suction fixing device, which belongs to the technical field of magnetic fixing devices, and comprises a columnar permanent magnet and a magnetic conducting sleeve for mounting the permanent magnet. The inner ring wall and the bottom inner wall of the magnetic conducting sleeve closely contact with the columnar lateral surface and the columnar bottom surface of the permanent magnet respectively, the end surface of the magnetic conducting sleeve and the columnar top surface of the permanent magnet are parallel and level, the magnetic conducting sleeve is an iron sleeve, and the permanent magnet is a neodymium-iron-boron magnet. The magnetic conducting sleeve is closely matched with the permanent magnet, two complete magnetic circuits are formed, attractive forces of the two complete magnetic circuits are mainly centralized on a plane acted by an attractive force, and a traditional single magnetic-suction fixing component is provided with a single magnetic circuit and has a plane acted by two attractive forces, so that the shortcoming of dispersion of attractive forces of a traditional structure is overcome. The magnetic conducting sleeve has magnetism after being magnetized, the weight of the neodymium-iron-boron permanent magnet can be accordingly reduced according to the operational need of the attractive forces, so that the cost of neodymium-iron-boron magnetic materials is reduced, and rare-earth resources can be saved.
Description
[technical field]
The utility model relates to a kind of magnetic-type immobilising device, and it is specially adapted to, but do not limit to as the immobilising device of the easily detachable filtering oil smoke web plate of range hood, belong to magnetic holder part technical field.
[background technology]
Press; With reference to figure 1, the easily detachable filtering oil smoke web plate that supplies range hood is the magnetic retaining element a unitary structure normally of usefulness fixedly, such as the cylinder type neodymium iron boron of employing
(towards the magnetic height); As everyone knows; The suction size of same magnetic material depends on its quality size, and its working face suction of this cylinder type neodymium iron boron is 4.5kg, and unit price is 3.8 yuan; The deficiency that the existence price ratio is lower, the practical necessity of improving.
[utility model content]
The utility model is directed against the deficiency of above-mentioned prior art existence and the magnetic-type immobilising device that a kind of suction is big, quality is little, cost is low, cost performance is high is provided.
For realizing above-mentioned technical assignment, the utility model provides following solution:
A kind of magnetic-type immobilising device; Comprise columned permanent magnet; Its improvement is also to comprise the flux sleeve that can supply permanent magnet to install, and flux sleeve and permanent magnet are tight fit, specifically; The internal ring wall of flux sleeve, end inwall are tight with post side, the post bottom surface of permanent magnet respectively and contact, and the end face of flux sleeve is concordant with the capital face of permanent magnet.
Above-mentioned flux sleeve is the irony cover, and above-mentioned permanent magnet is a neodymium iron boron.
Compared with prior art, the utlity model has following advantage and beneficial effect:
Flux sleeve and permanent magnet are tight fit; The utility model has formed two complete magnetic circuits thus; Its suction mainly concentrates on a suction plane, and traditional monomer-type magnetic retaining element is single magnetic circuit, has two suction planes (suction is all stronger); Overcome the deficiency that traditional structure suction disperses thus, therefore embodied the progressive of the utility model;
Have magnetic after flux sleeve is magnetized, according to the suction need of work can corresponding minimizing Nd-Fe-B permanent magnet quality, thereby reduce the neodymium-iron-boron magnetic material cost, can practice thrift rare earth resources, the utlity model has certain popularization value.

Fig. 2 is the front view of the magnetic-type immobilising device of the utility model;
Fig. 3 is the profile of Fig. 2.
[embodiment]
See also Fig. 2, shown in 3, be the preferred embodiment of the utility model.
A kind of magnetic-type immobilising device; Comprise columned permanent magnet 1 and the flux sleeve 2 that can supply permanent magnet to install; Flux sleeve 2 is tight fit with permanent magnet 1; Specifically, the internal ring wall 22 of flux sleeve 2, end inwall 20 are tight with post side 12, the post bottom surface 10 of permanent magnet 1 respectively and contact, and the end face 21 of flux sleeve 2 is concordant with the capital face 11 of permanent magnet 1.
Add man-hour, flux sleeve 2 adopts the irony cover, and its total height is 4mm, and sidewall thickness is 2mm; Bottom wall thickness is 2mm, and permanent magnet 1 adopts neodymium iron boron, and straight degree highly is 2mm for 12mm; Permanent magnet 1 is pressed in the flux sleeve 2 gets final product, the suction on its suction plane of magnetic-type immobilising device is 6.8kg, and the suction of the outer ring surface of the utility model, bottom surface all a little less than; The Nd-Fe-B permanent magnet unit price is 1 yuan, and irony cover unit price is 0.2 yuan, and adding up to total price is 1.2 yuan.
With the said specification of background technology is that
(towards the magnetic height), material are that the magnetic retaining element of cylinder type neodymium iron boron is compared: permanent magnet 1 has highly reduced 6mm; Volume has reduced 3/4, and the price of the utility model has reduced by 2.6 yuan.
Claims (2)
