[0023] Referring to the accompanying drawings: the electromagnetic release slide rail in this embodiment includes a slide rail body 1, and the slide rail body 1 performs the work of electromagnetic release slide rail. An electromagnet assembly 2 is arranged in the slide rail body 1, and an electromagnet bracket 3 is arranged in the electromagnet assembly 2. An electromagnet 4 is arranged on one side of the electromagnet bracket 3. The electromagnet 4 has a coil, which can achieve the effect of adsorbing the suction cup 7. An oblique stopper 5 is arranged on one side of the electromagnet 4. The oblique stopper 5 can realize the in-and-out function, that is, it can be extended and can be retracted. When working, it is used to block the slider 8, so that the door remains in a normally open state and stays at a required angle. After the work is completed, the slider 8 is left to close the door. The oblique stopper 5 is arranged on the electromagnet bracket 3, and the head end cross-section of the oblique stopper 5 is arranged in an inclined state. A spring 16 is connected to the oblique stopper 5, and the spring 16 is used to drive the in-and-out movement of the oblique stopper 5. A suction cup 7 is connected to the spring 16, and the action of the suction cup 7 can drive the movement of the spring 16. One end of the suction cup 7 is located at the end of the electromagnet 4, and the other end of the suction cup 7 rotates The suction cup 7 is connected to the electromagnet bracket 3 by a rotating shaft. In this way, in the entire electromagnet assembly 2, there is only a single electromagnet 4 and a suction cup 7. When one end of the suction cup 7 is adsorbed on the electromagnet 4, the other end can be rotated to allow the suction cup 7 to be smoothly adsorbed on the electromagnet 4. When the suction cup 7 needs to leave the electromagnet 4, the other end of the suction cup 7 can be rotated to allow the suction cup 7 to smoothly leave the electromagnet 4. In this way, the entry and exit of the inclined block 5 can be realized by a single electromagnet 4 and the suction cup 7, which changes the previous structure that requires multiple electromagnets to work. On the one hand, it reduces the production cost. On the other hand, the structure of a single electromagnet 4 and a suction cup 7 avoids the mutual interference caused by multiple electromagnets in the past, improves the work efficiency, improves the work efficiency of the electromagnetic release slide rail, and reduces the production cost of the electromagnetic release slide rail. A slider 8 is provided on one side of the electromagnet assembly 2, and the slider 8 is provided on the slide rail body 1. The remaining structure of the electromagnet assembly 2 is the same as the conventional one and is not repeated here.

[0024] Furthermore, the oblique stopper 5 is connected with an adjusting bolt 5-1 for adjusting the extension length of the oblique stopper 5, and the adjusting bolt 4-1 is arranged in the spring 1. In this arrangement, the adjusting bolt 5-1 is used to adjust the outward extension length of the oblique stopper 5, and the adjusting bolt 5-1 can be turned to change the extension length of the oblique stopper 5. When the force of blocking the slide block 8 needs to be increased, the adjusting bolt 5-1 is turned to allow more parts of the oblique stopper 5 to extend out, and more parts are used to block the slide block 8, thereby increasing the blocking force.

[0025] Further, the suction cup 7 is connected with a spring 2 7-1, which is located between the suction cup 7-1 and the slide rail body 1. With this arrangement, the spring 2 7-1 can push the suction cup 7 close to the electromagnet 4, so that the electromagnet 4 can absorb the suction cup 7 after generating suction force.

[0026] Furthermore, the slider 8 is connected to a rocker shaft 9 , and the rocker shaft 9 is connected to a rocker arm 10 .

[0027] Furthermore, the electromagnet support 3 is an electromagnet support 3 made of aluminum alloy material. In this way, the electromagnet support 3 made of aluminum alloy material is lightened in weight and reduced in cost.

[0028] Furthermore, the size of the electromagnet support 3 is 90 mm×25.2 mm×17 mm. This arrangement can reduce the length of the electromagnet 4, increase the installation space of the entire structure, facilitate installation, and reduce costs.

[0029] The remaining structures on the slide rail body 1 are the same as those of a conventional electromagnetic release slide rail and will not be described in detail.

[0030] When working, there is a micro switch on the outer side of the electromagnet 4 on the electromagnet assembly 2. The micro switch is connected to the circuit and can also directly energize the circuit. In this embodiment, the micro switch can be used for work, and the working voltage and current are DC24V and 0.06A. When the slider 8 slides over the oblique stopper 5 and contacts the micro switch on the outer side of the electromagnet 4, the circuit is energized, the electromagnet assembly 2 is energized, and the magnetic field generated by the electromagnet 4 sucks the suction cup 7 on the electromagnet 4. After the suction cup 7 is sucked, the oblique stopper 5 is pushed out, and the oblique stopper 5 extends out from the electromagnet bracket 3. Since the head end cross-section of the oblique stopper 5 is arranged in an inclined state, and the inclined side of the oblique stopper 5 is located on the front side, the oblique stopper 5 blocks the slider 8 to position the slider 8, so that the door remains in the normally open state, thereby The door can be kept in a normally open state at a set angle to ensure smooth evacuation, avoid casualties and property losses, and ensure ventilation of the building on weekdays. When a fire occurs, the circuit is powered off. After the circuit is powered off, the electromagnet assembly 2 is powered off, the magnetic field of the electromagnet 4 disappears, the adsorption relationship between the suction cup 7 and the electromagnet 4 is disconnected, the force of the oblique block 5 blocking the slider 8 disappears, and the slider 8 moves back under the action of the door closer assembly, pressing the oblique block 5 into the electromagnet bracket 3, the oblique block 5 retracts into the electromagnet bracket 3, and the slider 8 continues to move to the corresponding position to automatically close the door, thereby preventing the spread of fire, avoiding casualties and property losses. In the entire working process, fire linkage can be achieved, and the power can be cut off and the door can be closed in real time when an emergency fire occurs to avoid the spread of fire.

[0031] The characteristics of the embodiments of the utility model are as follows: the electromagnetic release slide rail of the utility model has a reasonable structure, and the operation of the slide rail main body can be realized through the structure of a single electromagnet and a suction cup, which changes the previous structure that requires multiple electromagnets to work. On the one hand, it reduces the production cost, and on the other hand, the use of a single electromagnet and a suction cup structure reduces interference and improves work efficiency. The working efficiency of the electromagnetic release slide rail is improved, the production cost of the electromagnetic release slide rail is reduced, the use effect is good, and it is conducive to promotion.
