The first permanent magnet 700 is located at one side of the soft magnet 600 and can magnetize the front end or the rear end of the soft magnet 600.
In this embodiment, the first permanent magnet 700 may be located at the left side of the soft magnet 600, and the first permanent magnet 700 may magnetize the rear end of the soft magnet 600. The first permanent magnet 700 is a bar magnet, and the middle part of the first permanent magnet 700 is fixedly connected with the rotating shaft 512.
Because the front end of second permanent magnet is the N utmost point, and soft magnet 600 is located the front side of second permanent magnet, consequently, can drive first permanent magnet 700 through pivot 512 and rotate to first permanent magnet 700 and be in the horizontality, at this moment, first permanent magnet 700 extends along left right direction, and the S utmost point of first permanent magnet 700 just faces the rear end of soft magnet 600, through the magnetization, makes the rear end of soft magnet 600 become the N utmost point, so, has magnetic repulsion between second permanent magnet and the soft magnet 600, consequently, the relative soft magnet 600 of second permanent magnet can move backward. Also, at this time, the bolt 511 of the lever handle 510 is just snap-coupled with the lock holder 520, as shown in fig. 2.
When driving first permanent magnet 700 through pivot 512 and rotating 90 back, make first permanent magnet 700 be in vertical state, at this moment, first permanent magnet 700 extends along the upper and lower direction, and soft magnet 600 is located the middle part position of first permanent magnet 700, and soft magnet 600 can not receive first permanent magnet 700's magnetization, so, has magnetic attraction between second permanent magnet and soft magnet 600, consequently, the relative soft magnet 600 of second permanent magnet can move forward. At this time, the latch bolt 511 of the lever handle 510 and the lock holder 520 are released from the engagement, so that the user can open the casement window, as shown in fig. 4.
Since the contact surface between the first sealing member 300 and the sliding groove 112 is smooth and the friction is small, the first sealing member 300 moves backward rapidly under the action of the magnetic repulsive force and moves forward rapidly under the action of the magnetic attractive force. For example, the first sealing member 300 may be slidably coupled to the optical axis extending in the front and rear directions of the movable sash 110. The first permanent magnet 700 has stronger magnetism than the second permanent magnet, and thus the first permanent magnet 700 can magnetize the soft magnet 600.
In addition, in order to mount the first permanent magnet 700 on the rotating shaft 512, a through hole may be formed on a front side surface of the aluminum profile of the movable window frame 110, the through hole being communicated with the inner cavity 111, and the size of the through hole may allow the first permanent magnet 700 to pass therethrough.
In other embodiments, the handle 510 can rotate 180 °, so when the S pole of the first permanent magnet 700 is directly opposite to the rear end of the soft magnet 600, the rear end of the soft magnet 600 becomes the N pole, and at this time, the latch tongue 511 of the handle 510 is in snap-fit connection with the lock base 520. Then, after the handle 510 is turned by 180 °, the N pole of the first permanent magnet 700 directly faces the rear end of the soft magnet 600, and the rear end of the soft magnet 600 becomes the S pole, at this time, the latch bolt 511 of the handle 510 releases the fastening effect with the lock seat 520, and since the front end of the second permanent magnet is the N pole, there is a large magnetic attraction effect between the second permanent magnet and the soft magnet 600.
Of course, in other embodiments, the second permanent magnet extends up and down, the upper end of the second permanent magnet is N-pole, the lower end of the second permanent magnet is S-pole, and the rear end of the soft magnet 600 is opposite to the upper end of the second permanent magnet in the front-rear direction.
It can be understood that the magnetic action between the second permanent magnet and the soft magnet 600 can be utilized to drive the first sealing element 300 to move forward, so that the first sealing element 300 is far away from the first contact surface of the sealing rubber strip 200, therefore, the sealing rubber strip 200 is restored to the original state without the squeezing action, the second contact surface of the sealing rubber strip 200 is separated from the second sealing element 400, and the casement window can be opened more easily. After the first encapsulation 300 is moved forward to a position, the second permanent magnet comes into contact with the soft magnet 600.
After the casement window is closed, the handle 510 is rotated, the rotating shaft 512 drives the first permanent magnet 700 to rotate for a certain angle around the axial direction extending from front to back, so that the soft magnet 600 is magnetized under the action of the magnetic field of the first permanent magnet 700, one end of the soft magnet 600 close to the second permanent magnet is magnetized, the magnetic pole of the soft magnet is opposite to that of the second permanent magnet close to the soft magnet 600, the second permanent magnet is driven to move backwards under the action of magnetic repulsion force, the first sealing element 300 is extruded on the first contact surface of the sealing rubber strip 200, and the sealing rubber strip 200 is forced to deform; when the rotating shaft 512 drives the first permanent magnet 700 to rotate in the opposite direction, the soft magnet 600 loses the magnetization function of the first permanent magnet 700, and demagnetization is realized, so that the second permanent magnet can be magnetically attracted with the soft magnet 600.
In this embodiment, the handle 510 is located on a side of the movable sash 110 away from the hinge. If the hinge is located at the left side of the movable sash 110, the handle 510 is located at the right side of the movable sash 110. Then, the soft magnet 600 and the second permanent magnet are both located on the right side of the movable window frame 110. The handle 510 may be an existing ball seven-letter handle 510, the handle 510 is installed at a front side surface of the movable window frame 110, a bolt 511 of the handle 510 is exposed, and the lock holder 520 is fixed at a front side surface of the fixed window frame 130 by screws.
It can be understood that, by such an arrangement, the latch tongue 511 can be exposed out of the movable window frame 110, so that the movable window frame 110 can vacate enough space to accommodate the rotating shaft 512, the first permanent magnet 700, the soft magnet 600 and the second permanent magnet, thereby preventing the movable window frame 110 from being oversized in front and rear.
Because the handle 510 is located on the aluminum profile of the right end of the movable window frame 110, then, as for the internal structure of the other aluminum profiles of the movable window frame 110 as shown in fig. 3, the handle 510, the lock base 520, the rotating shaft 512, the soft magnet 600, the first permanent magnet 700 and the second permanent magnet are absent from the aluminum profile of the right end, and the other parts are consistent.
It is understood that the second permanent magnet corresponds to a movable portion of the driving mechanism, is fixedly coupled to the first sealing member 300, and drives the first sealing member 300 to move forward or backward.
In some embodiments, the casement window further includes a seal 800.
In some embodiments, the first contact surface of the sealant strip 200 is provided with two convex portions, each convex portion is annular, the two convex portions are spaced apart from each other and define the slot 220, and the opening of the slot 220 is disposed forward, so that the abutting block 310 can extend into the slot 220. The slot 220 is located at the front side of the cavity 210. After the abutment block 310 is inserted into the insertion slot 220, the abutment block 310 can press the wall surface of the insertion slot 220, thereby causing the deformation of the sealing rubber strip 200.
It can be understood that, with the above-mentioned structural arrangement, when the abutting block 310 is pressed against the wall surface of the slot 220, not only the deformation of the joint strip 200 can be promoted and the second contact surface is made to closely adhere to the second sealing member 400, but also the two convex portions can be made to approach and closely adhere to the abutting block 310, so as to increase the contact area between the joint strip 200 and the first sealing member 300, and thus enhance the sealing effect between the joint strip 200 and the first sealing member 300.
As shown in fig. 5 to 7, a third embodiment of the present invention provides a casement window with good sealing performance, which is different from the second embodiment in that the structure and the operation principle of the driving mechanism are different.
In this embodiment, the structure of the driving mechanism still includes the rotating shaft 512, the soft magnet 600 and the second permanent magnet, and only the dial block 900 is used to replace the first permanent magnet 700. The dial block 900 is fixedly connected to the rotating shaft 512, when the handle 510 is rotated, the dial block 900 can rotate along with the rotating shaft 512 along the rotating axis extending back and forth, and the circumferential direction of the dial block 900 is perpendicular to the extending direction of the rotating axis. Also, the inner cavity 111 of the movable window frame 110 communicates with the sliding groove 112 so that the dial block 900 extends into the sliding groove 112.
The rear side of the dial block 900 is gradually recessed forward along the circumference of the dial block 900. Since the rear side surface of the dial block 900 is always in contact with the front side surface of the first sealing member 300, the contact position of the dial block 900 and the first sealing member 300 changes, specifically, the position of the contact position changes in the front-rear direction, in the process that the dial block 900 rotates along with the rotation of the rotating shaft 512.
The number of the soft magnets 600 and the number of the second permanent magnets are not limited to one. In this embodiment, each soft magnet 600 and each second permanent magnet are arranged in a front-to-back opposing manner, wherein one soft magnet 600 is located below the dial block 900 and the other soft magnet 600 is located above the dial block 900. In addition, as for the left-end aluminum section, the upper-end aluminum section, and the lower-end aluminum section of the movable window frame 110, a second permanent magnet and a soft magnet 600 may be provided, as shown in fig. 3.
As shown in fig. 5, at this time, the lock tongue 511 of the handle 510 is in snap-fit connection with the lock seat 520, the casement window is in a closed state, and the contact position of the first sealing element 300 and the toggle block 900 is located behind the movable window frame 110, so that the first sealing element 300 moves backwards relative to the movable window frame 110, and the first sealing element 300 can be pressed against the first contact surface of the sealing rubber strip 200. It will be appreciated that during rotation of the dial block 900, the contact of the dial block 900 with the primary seal 300 moves rearward, causing the primary seal 300 to move rearward.
As shown in fig. 6, at this time, the locking tongue 511 of the handle 510 releases the locking action with the lock holder 520, so that the user can open the casement window, and the contact position of the first sealing member 300 and the toggle block 900 is located forward relative to the movable window frame 110, so that the first sealing member 300 moves forward relative to the movable window frame 110, and the first sealing member 300 can be separated from the first contact surface of the sealing rubber strip 200. It can be understood that, during the reverse rotation of the dial block 900, the contact position of the dial block 900 and the first sealing member 300 moves forward, and at this time, the first sealing member 300 moves forward due to the magnetic attraction between the second permanent magnet and the soft magnet 600, so that the first sealing member 300 can maintain contact with the rear side surface of the dial block 900.
Because the handle 510 is located the aluminium alloy of the right-hand member of movable window frame 110, then, as shown in fig. 7 to the inner structure of the other aluminium alloys of movable window frame 110, relative right-hand member's aluminium alloy, lacked handle 510, lock seat 520, pivot 512 and shifting block 900, other parts are unanimous.
In this embodiment, the soft magnetic body 600 may be replaced with a magnet, and the first sealing member 300 may be made of iron.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous modifications and substitutions without departing from the spirit of the present invention and within the scope of the appended claims.
