In figure：1- doorframes, 2- outer frameworks, 3- accommodating cases, 4- permanent magnets, 5- pads, 6- apical pores, 7- sealing rings, 8- are installed Frame, 9- spring A, 10- voussoir, 11- spring Bs.

Specific embodiment

The technical scheme of this patent is described in more detail with reference to specific embodiment.

Refer to Fig. 1, a kind of magnetic sealing device of locking off-type bar, including device body, described device body Mainly by accommodating case 3, permanent magnet 4, pad 5, apical pore 6, sealing ring 7, mounting bracket 8, spring A9, voussoir 10, the structure of spring B 11 Into；Described device body is set to two parts, and a part for device body is arranged on the top of doorframe 1, device body it is another The inside of outer framework 2 is partially installed on, device body sets accommodating case 3, and the accommodating case 3 is plastic material, the accommodating case 3 Inwall be frosted structure, by the structure of frosted come increasing friction force, the inside of the accommodating case 3 sets permanent magnet 4, described Interference fit between permanent magnet 4 and accommodating case 3, the bottom of permanent magnet 4 sets pad 5, and the pad 5 is plastic material, described The size of pad 5 and the size of permanent magnet 4 are completely the same, are also interference fit, permanent magnet 4 and pad between pad 5 and accommodating case 3 The number of combinations of piece 5 is changed according to personal use habit, such as when being used in the bedroom door or window of family The ratio of permanent magnet 4 and pad 5 is 3 to 5, and permanent magnet 4 and pad 5 are 5 to 3 when use on the door in classroom, are led to Cross the ratio of change permanent magnet 4 and pad 5 to change the size of the suction of device body, the bottom of the accommodating case 3 sets top Hole 6, the apical pore 6 is connected with the inside of accommodating case 3, by the effect of apical pore 6, then with the use of push rod by accommodating case 3 Internal permanent magnet 4 or pad 5 is ejected, and the end of the accommodating case 3 sets sealing ring 7, and the sealing ring 7 is rubber material Matter, the end of sealing ring 7 is fixedly connected with the end of accommodating case 3, the inner ring diameter of the sealing ring 7 just with accommodating case 3 Inner ring diameter is in the same size；The inside of the outer framework 2 is also provided with accommodating case 3, the internal structure of the inner containment box 3 of outer framework 2 Internal structure with the inner containment box 3 of doorframe 1 is consistent, and the top of accommodating case 3 inside the outer framework 2 sets mounting bracket 8, described By screw thread twist-on between the outer wall of mounting bracket 8 and accommodating case 3, the top of the mounting bracket 8 sets spring A9, the spring A9 Two are set, is fixedly connected between the top of the spring A9 and the inwall top of outer framework 2, bottom and the peace of the spring A9 Be fixedly connected between the top for shelving 8, the sidewall bottom of the mounting bracket 8 sets spring B 11, the top of the spring B 11 with The sidewall bottom of mounting bracket 8 is fixedly connected, and is fixedly connected between the bottom of spring B 11 and voussoir 10, and the voussoir 10 is square Body structure, voussoir 10 passes through to be fixedly connected between screw and the inwall of outer framework 2, by spring A9 and spring B 11 to device sheet The top half of body is resetted.

Accommodating case 3 when closing the door inside outer framework 2 connects permanent magnet 4 can be to bottom offset in the presence of magnetic force, dress The interphase interaction of two parts up and down of body is put, connection of combining closely is carried out by the effect of upper and lower two sealing rings 7, formed Sealing state, when enabling, two parts up and down of device body are separated, now the accommodating case 3 and permanent magnet inside outer framework 2 4 need to be resetted, because door is that spring A9 is extended state when close, spring B 11 is compressive state, now spring A9 and spring B 11 are required for recovering deformation, therefore make accommodating case 3 and forever by the effect that spring A9 and spring B 11 reply deformation Magnet 4 resets, and the coefficient of elasticity of spring reduces when when existing single stretching or compression use certain, spring The ability for recovering deformation after deformation reduces, therefore can cause releasing for device body, and then device body can be caused to be dragged to The outside of installation position, prolonged frictional impact comes off between device body meeting and doorframe 1, causes device body to use effect Fruit is deteriorated, the mode that the stretching single compared to existing device or compression spring are resetted, the service life time of spring It is longer.

The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party Formula, in the ken that one skilled in the relevant art possesses, can also be on the premise of this patent objective not be departed from Make a variety of changes.
