The swing locking block 17 is in a cuboid shape, a circular groove is formed in the front end of the swing locking block, and the magnet II is embedded in the front end of the swing locking block and is fixed by glue. The opposite end faces of the magnet II and the magnet I are homopolar and generate repulsion. The lock body baffle is provided with a through hole II, the through hole II of the lock body baffle is aligned with the opening of the lock body shell, and the lock body shell is welded on the lock body baffle; the lock body baffle 18 is provided with two screw holes II 181 for connecting with the door lock hole. The edge 182 of the lock body baffle plate contacting with the bolt is arc-shaped, and is arranged on the door to protect the door edge from being damaged by collision, and simultaneously, after contacting with the bolt 9, the bolt 9 can move more smoothly after being collided.
When the door is closed, the front end of the lock tongue is positioned in the lock body shell, the tension spring 6 is in a natural state or a contraction state, the swing locking block 17 is positioned in the through groove, and a gap is formed between the lock tongue and the swing locking block; when the door is opened, the swing locking block 17 is positioned in the lock body shell, the magnet I on the lock tongue and the magnet II of the swing locking block generate repulsive force, the lock tongue is positioned in the lock tongue shell, and the tension spring 6 is in a contraction state.
Because the magnets are arranged in the double-magnet lock body of the silent door, the metal material in the whole lock body is made of non-magnetic materials, such as stainless steel, aluminum and other metals; the installed door material is suitable for a plastic steel door, an aluminum alloy door, a wooden door and the like; the lock body is made of non-magnetic materials, so that the lock body has oxidation resistance and can be kept in a humid environment for a long time.
In this embodiment, the angle β between the inclined surface of the lower portion of the tail end of the swing lock piece and the inner end surface of the tail end of the lock body housing is 15 to 17 degrees.
In this embodiment, the clearance between spring bolt outer wall and the spring bolt shell side inner wall is 0.1 mm. As a transformation, the clearance between the outer wall of the lock tongue and the inner wall of the side face of the lock tongue shell can be determined according to actual conditions, and the lock tongue can move smoothly in the lock tongue shell as long as the lock tongue can be ensured.
The use process comprises the following steps: the door frame fixed end spring bolt is installed in the locked groove on the fixed door frame, and the screw is put into the upper and lower screw holes I of the spring bolt fixed baffle 1 to be screwed down or fixed by the rivet. The door lock body is arranged in a door lock hole, and is placed into the upper screw hole II and the lower screw hole II of the lock body baffle 18 by screws or rivets and fixed. The rotation locking piece is in an inclined state, that is, the rotation locking piece is positioned in the through groove 131. Then, a handle is installed, the shape and the use of the handle are not described, and the installation hole positions are common to handles on the market.
When closing the door, promote the room door and remove toward the direction of closing, when the room door gets into the door frame and is close half region, the slope terminal surface 91 department of the first contact spring bolt 9 of edge circular arc part of lock body baffle 18 one end, spring bolt 9 is at the in-process of striking, receives the restriction of direction spacer pin 11 and guide way 12, can only be steady to the inside removal of spring bolt shell 2, at this moment check valve 3 is opened, with gaseous a large amount of discharges, the speed of spring bolt 9 inward movement can be faster slightly, up to with the door limit parallel and level. The door continues to be closed towards the door frame until the bolt 9 enters the lock body shell 13 to be clamped (the front end of the bolt 9 is provided with an inclined end surface 91 which is more easy to enter a lock hole and be clamped), at this time, the tension spring 6 ejects the bolt 9 outwards, the one-way valve 3 is closed, only quantitative air intake can be realized by the exhaust hole 4, the bolt 9 slowly and stably moves outwards until the guide limiting pin 11 is clamped on the guide groove 12, the bolt 9 stops moving, the door is locked, and one-time door closing action is completed (as shown in figures 10-11).
When opening the door, rotatory door handle is installed in rotating hole 15, and it is rotatory to drive rotatory catch 16, and the horizontal position is reachd to the swing locking piece, and cylinder magnet II repels with I peer of cylinder magnet and produces powerful magnetic force (magnetic force is greater than tension spring 6's spring-supported power), and push spring bolt 9 to and remove in spring bolt shell 2, check valve 3 opens, and spring bolt 9 removes in to spring bolt shell 2 fast, and when spring bolt 9 left lock body shell 13, it can to open the door. Due to the fact that the bolt 9 adopts the extension delay design, noise generated by bolt rebounding can be greatly reduced.
