[0039] (1) Unlock drive through magnetic repulsion
[0040] When a fire breaks out, the processor issues an energization command to the electromagnetic coil 31a. After the electromagnetic coil 31a is energized, the left end of the swing rod 30b (the end with the magnetic component 31b) is lifted upwards, and the right end swings downward, so that the first One matching part b1 is separated from the second matching part b2 to be unlocked, and the booster module 2 pushes the door to be closed and set.
[0041] (2) After the glass column is broken by high temperature, the top support part is reset to unlock the drive
[0042] When a fire breaks out, the glass column 7 will explode as the indoor temperature rises, and the supporting part 60 of the second limiting part 6 will push the left end of the swing rod 30b upwards and the right end downwards under the reset of the torsion spring. Swing, so that the first matching part b1 is separated from the second matching part b2 to unl...

The invention relates to a sliding door closer comprising a mounting base and a boosting module and a locking mechanism for relatively locking the mounting base and the boosting module, wherein the locking mechanism comprises a locking part for relatively locking the mounting base and the boosting module and an unlocking part; the locking part comprises an oscillating bar arranged on the mounting base in a way of vertically oscillating from the middle around the left and right ends of a horizontally-arranged pivot, wherein the right end of the oscillating bar is provided with a first matching part; the boosting module is provided with a second matching part matched with the first matching part; the unlocking part comprises an electromagnetic coil located at the left end of the oscillating bar; and the door closer also comprises a processor capable of sending an electrifying instruction to the electromagnetic coil according to indoor information. When a fire happens, the electrifying instruction can be rapidly and accurately sent to the electromagnetic coil, a door is unlocked by oscillating bar rotation driven by the repulsion of a magnetic force, and then, the door is pushed to be closed by the boosting module, so that the spread of the fire is effectively avoided; and meanwhile, the sliding door closer is simple in structure, convenient to use and low in cost.
Description
technical field [0001] The invention relates to a sliding door closer. Background technique [0002] There are two main types of door closers: one is an electric door closer; the other is a movable door closer controlled by mechanical principles. It is mainly that in the event of a fire, it can automatically close the door to prevent the circulation of air, thereby controlling the spread of the fire. [0003] However, the door closers used in the market have the following characteristics: [0004] 1) The structure is complex, the operation is inconvenient, and accidents are prone to occur; [0005] 2), the production cost is high, and there is no advantage in market competition. Contents of the invention [0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved sliding door closer. [0007] In order to solve the problems of the technologies described above, the present invention takes t...
