[0002] An electromagnetic lock is a safety device that uses electromagnetic principles to achieve a locking function. It usually consists of components such as an electromagnet, a lock body, a controller, and a power source.

[0003] For the existing electromagnetic locking safety door locks on the market, the rear covers are all integrated, with a simple structure, but poor heat dissipation. The continuous working temperature will be higher, and continuous high-temperature operation will affect the service life of the safety door lock. Therefore, we propose a heat dissipation structure for the safety door lock. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a heat dissipation structure for a safety door lock. By setting a metal mounting plate and a rear cover, the heat of the electromagnet can be conducted through fixation. At the same time, the large-area contact between the metal mounting plate and the electromagnet effectively increases the heat dissipation area. Under the same power, the larger the area, the better the heat dissipation. It is more helpful to dissipate the heat of the electromagnet of the electromagnetic lock during long-term continuous operation, with good heat dissipation effect. The continuous working temperature is about 10 degrees Celsius lower than that of peer competitors. By setting the rear cover, the rear cover can also play the role of a bracket and support the electromagnet.

[0023] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0024] Referring to Figures 1-7 As shown, the present invention provides a heat dissipation structure for a safety door lock in a preferred embodiment, which includes a heat dissipation component 1, a lock body 2 and an electromagnet 3. The heat dissipation component 1 includes a metal mounting plate 101. Above the metal mounting plate 101, a rear cover 102 is movably arranged. The rear cover 102 is fixedly connected to the lock body 2. The lock body 2 is installed on the door frame through the rear cover 102, and the electromagnet 3 is movably connected to the lock body 2.

[0025] By providing the metal mounting plate 101 and the rear cover 102, the heat of the electromagnet 3 can be conducted by fixation. At the same time, the large-area contact between the metal mounting plate 101 and the electromagnet 3 effectively increases the heat dissipation area. Under the same power, the larger the area, the better the heat dissipation, which is more helpful for dissipating the heat of the electromagnet 3 of the electromagnetic lock during long-term continuous operation. The heat dissipation effect is good, and the continuous working temperature is about 10 degrees Celsius lower than that of the same industry competitors. By providing the rear cover 102, the rear cover 102 can also play the role of a bracket at the same time, supporting the electromagnet 3, and there is no need to design a separate bracket.

[0026] Referring to Figures 1-7 As shown, the metal mounting plate 101 has an annular structure. The metal mounting plate 101 is installed on the door body. The metal mounting plate 101 is adapted to the electromagnet 3, and the metal mounting plate 101 is movably sleeved on the outer wall of the electromagnet 3.

[0027] By providing the annular metal mounting plate 101, it is convenient to sleeve the metal mounting plate 101 outside the electromagnet 3. Moreover, both the metal mounting plate 101 and the rear cover 102 are made of metals with better thermal conductivity, which can improve the heat dissipation performance of this electromagnetic lock.

[0028] Referring to Figures 1-7 As shown, a pair of first screw holes 103 are provided on the outside of the rear cover 102. The pair of first screw holes 103 are distributed along the horizontal center line of the rear cover 102.

[0029] Referring to Figures 1-7 As shown, a pair of second screw holes 104 are provided on the outside of the rear cover 102. The pair of second screw holes 104 are distributed along the vertical center line of the rear cover 102.

[0030] By providing the first screw holes 103 and the second screw holes 104, and using fasteners such as screws to penetrate the first screw holes 103 and the second screw holes 104, it is convenient to install the lock body 2 and the rear cover 102 on the door frame, facilitating the cooperation between the electromagnet 3 and the lock body 2.

[0031] Refer to Figures 1-7 As shown, a lock body housing 4 is installed outside the lock body 2, and a connector 5 is fixedly connected to the outer end of the lock body housing 4.

[0032] By providing the lock body housing 4, the lock body 2 can be protected, and the provision of the connector 5 facilitates the connection and energization of the cable to the lock body 2.

[0033] Specific implementation process: First, use fasteners such as screws to pass through the first screw hole 103 and the second screw hole 104 to install the lock body 2 and the rear cover 102 on the door frame;

[0034] The provision of the connector 5 facilitates the connection and energization of the cable to the lock body 2. When the electromagnet 3 and the lock body 2 are energized, the lock body 2 makes the electromagnet 3 protrude and sleeve together with the metal mounting plate 101 to close the door body and the door frame. When the lock body 2 is not energized, the lock body 2 will make the electromagnet 3 retract and separate the electromagnet 3 from the metal mounting plate 101, and the door body can be automatically opened;

[0035] The metal mounting plate 101 and the rear cover 102 can conduct heat of the electromagnet 3 through fixation. At the same time, the large-area contact between the metal mounting plate 101 and the electromagnet 3 effectively increases the heat dissipation area. Under the same power, the larger the area, the better the heat dissipation, which is more helpful for dissipating heat of the electromagnet 3 of the electromagnetic lock working continuously for a long time. The heat dissipation effect is good, and the continuous working temperature is about 10 degrees Celsius lower than that of the same industry competitors. By providing the rear cover 102, the rear cover 102 can also play the role of a bracket and support the electromagnet 3.
