Description

A modular, quick-installation electro-permanent magnet door lock device Technical Field

[0001] This utility model relates to the field of electro-permanent magnet door lock technology, specifically a modular and quick-installation electro-permanent magnet door lock device. Background Technology

[0002] An electro-permanent magnet door lock is a security device that uses the principle of electromagnetic induction to achieve door locking functionality. It typically includes key components such as a permanent magnet and a reed switch (or proximity switch). The permanent magnet generates a constant magnetic field. When the door is closed, the permanent magnet approaches the reed switch, causing its contacts to close or open, thereby changing the circuit state and synchronizing the door lock with the signal output. When the access control system identifies an authorized person, it cuts off the power or changes the magnetic field state, causing the door lock to lose its magnetic attraction, thus allowing the door to open.

[0003] A search revealed Chinese patent document CN109339588A, which discloses a high-security electromagnetic door lock based on internet control. This lock uses an electromagnet and a permanent magnet to electrically control the door's opening and closing. After identity verification, the lock automatically opens. Combined with a pop-out device on the door, it automatically opens. A mechanical lock allows manual key retrieval in case of power outages, network interruptions, or other emergencies. The combination of these two methods is convenient and does not hinder key retrieval. Furthermore, the use of springs, steel balls, and limiting grooves slightly limits the electromagnetic bolt, preventing it from sliding open and ensuring key security. However, the following issues remain:

[0004] The aforementioned modular, quick-installation electro-permanent magnet door lock device is convenient to disassemble and repair when the door lock malfunctions, and it is also convenient to reinstall the door lock after repair. Summary of the Invention

[0005] The purpose of this utility model is to provide a modular and quick-installation electro-permanent magnet door lock device to solve the problem in the above-mentioned modular and quick-installation electro-permanent magnet door lock device that is inconvenient to disassemble and repair when the door lock malfunctions, and is also convenient to reinstall the door lock after repair.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reinforced electrical insulation rubber sheet to prevent dispersion, comprising a positioning base, wherein two sets of positioning bases are provided, and a base plate is fixed between the two sets of positioning bases. The cross-section of the positioning base and the base plate is a "U" shaped structure. A door lock body is slidably connected to the side of the base plate, and the cross-sectional shape of the door lock body is also a "U" shaped structure. A limiting plate is also fixed between the positioning bases, and the limiting plate and the base plate are vertically fixed. A door body is provided on the inner side of the positioning base.

[0007] The positioning base has positioning clamps distributed on the side near the door, and the side of the positioning clamps near the door is covered with an anti-slip pad. A shrinkage groove is provided at the connection between the positioning base and the positioning clamps. Two sets of first adjustment blocks are fixed on the side of the positioning clamps away from the anti-slip pad. The two sets of first adjustment blocks are distributed vertically and parallel to each other. An adjustment plate is slidably connected to the side of the first adjustment block away from the positioning clamps. The adjustment plate is slidably connected inside the shrinkage groove. An adjustment screw is provided through the middle of the adjustment plate.

[0008] Preferably, two sets of positioning posts are fixed to the side of the base plate, and the positioning posts are inserted into and connected to the side of the door lock body.

[0009] Preferably, four sets of positioning bolts are provided at the connection points between the two ends of the door lock body and the limiting plate, and bolt holes are provided at the connection points between the limiting plate and the positioning bolts.

[0010] Preferably, the surface of the anti-slip mat is provided with a corrugated strip structure in opposite directions, and the connection between the positioning base and the door is also covered with an anti-slip mat.

[0011] Preferably, two sets of parallel mirror-distributed limiting rods are fixed at the front and rear ends of the first adjusting block, and a partition is slidably connected between the two sets of the first adjusting blocks. The partition is disposed inside the shrinkage groove and is fixedly connected to the positioning base. Limiting sliders are fixed at the two ends of the partition near the limiting rods, and a limiting groove is formed at the connection between the limiting slider and the limiting rod.

[0012] Preferably, two sets of second adjusting blocks are vertically fixed at the upper and lower ends of the adjusting plate near the first adjusting block.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1, please refer to Figures 1-5. This utility model provides a modular, quick-installation electro-permanent magnet door lock device, including a positioning base 1, a limiting plate 101, a base plate 102, a positioning post 103, bolt holes 104, positioning bolts 105, a contraction groove 106, a door lock body 2, a positioning clamping plate 3, an anti-slip pad 301, a first adjusting block 302, a limiting rod 303, a limiting groove 304, a partition 4, a limiting slider 401, an adjusting plate 5, a second adjusting block 501, an adjusting screw 6, a knob 601, and a door body 7. The positioning base 1 is provided in two sets, and a base plate 102 is fixed between the two sets of positioning base 1. The cross-section of the positioning base 1 and the base plate 102 is a "U" shaped structure. The door lock body 2 is slidably connected to the side of the base plate 102, and the cross-section of the door lock body 2 is also a "U" shaped structure. Two sets of positioning posts 103 are fixed to the side of the base plate 102. The positioning posts 103 are inserted and connected to the side of the door lock body 2. The support of the door lock body 2 by the positioning posts 103 can make the installation of the door lock body 2 on the positioning base 1 more stable.

[0026] Specifically, as shown in Figures 1 and 2, four sets of positioning bolts 105 are provided at the connection between the two ends of the door lock body 2 and the limiting plate 101. Bolt holes 104 are provided at the connection between the limiting plate 101 and the positioning bolts 105. The positioning bolts 105 can be used to conveniently install and fix the door lock body 2 and the positioning base 1.

[0027] A limiting plate 101 is also fixed between the positioning bases 1, and the limiting plate 101 and the base plate 102 are vertically fixed together. A door 7 is provided on the inner side of the positioning base 1.

[0028] Specifically, as shown in Figures 2 and 4, a positioning clamp 3 is distributed on the side of the positioning base 1 near the door body 7. The side of the positioning clamp 3 near the door body 7 is covered with an anti-slip pad 301. The surface of the anti-slip pad 301 is provided with a corrugated strip structure in opposite directions. The connection between the positioning base 1 and the door body 7 is also covered with an anti-slip pad 301. This can increase the friction between the anti-slip pad 301 and the door body 7, prevent the positioning base 1 from sliding up and down, and make the installation of the positioning base 1 more stable.

[0029] Specifically, as shown in Figures 4 and 5, a shrinkage groove 106 is provided at the connection between the positioning base 1 and the positioning clamp 3. Two sets of first adjusting blocks 302 are fixed on the side of the positioning clamp 3 away from the anti-slip pad 301. The two sets of first adjusting blocks 302 are distributed vertically and horizontally. Two sets of parallel mirror-distributed limiting rods 303 are fixed at the front and rear ends of the first adjusting blocks 302. A partition 4 is slidably connected between the two sets of first adjusting blocks 302. The partition 4 is set inside the shrinkage groove 106 and is fixedly connected to the positioning base 1. Limiting sliders 401 are fixed at the two ends of the partition 4 near the limiting rods 303. A limiting groove 304 is provided at the connection between the limiting sliders 401 and the limiting rods 303. The limiting rods 303 can increase the stability of the positioning clamp 3 when it moves horizontally and can also prevent the positioning clamp 3 from moving excessively and detaching from the positioning base 1. The limiting groove 304 can limit the movement distance of the positioning clamp 3.

[0030] In Example 2, specifically as shown in Figures 3, 4, and 5, an adjustment plate 5 is slidably connected to the side of the first adjustment block 302 away from the positioning clamping plate 3. Two sets of second adjustment blocks 501 are vertically fixed to the upper and lower ends of the adjustment plate 5 near the first adjustment block 302. The second adjustment blocks 501 are slidably connected to the first adjustment block 302, and the connection surface between the first adjustment block 302 and the second adjustment block 501 is an inclined structure. In this way, when the second adjustment block 501 moves, it can push the first adjustment block 302 to move horizontally, and then push the first adjustment block 302 outward and clamp it to the side of the door body 7.

[0031] Specifically, as shown in Figures 4 and 5, the connection between the adjusting plate 5 and the adjusting screw 6 is provided with a corresponding threaded hole, and the adjusting plate 5 and the adjusting screw 6 are threadedly connected, so that the rotation of the adjusting screw 6 can drive the adjusting plate 5 to move.

[0032] Specifically, as shown in Figures 4 and 5, the adjusting plate 5 is slidably connected inside the shrinkage groove 106, and an adjusting screw 6 is provided through the middle of the adjusting plate 5. A knob 601 is fixed at one end of the adjusting screw 6. The knob 601 is distributed on the outer side of the positioning base 1 and is rotatably connected to the positioning base 1. The adjusting screw 6 on the inner side can be rotated by the outer knob 601.

[0033] In use, the positioning base 1 can be set on one side of the door body 7. Rotating the knob 601 rotates the adjusting screw 6, which in turn rotates the adjusting screw 6. The rotating adjusting screw 6 then drives the second adjusting block 501 to slide on the side of the first adjusting block 302 via the adjusting plate 5. The inclined structure then pushes the first adjusting block 302 outwards, causing the positioning clamp 3 to move outwards and contact the door body 7 via the anti-slip pad 301 on one side. This clamps and fixes the positioning base 1 onto the door body 7, allowing the door lock body 2, mounted on the positioning base 1, to be quickly installed on the door body 7. During maintenance, the positioning bolt 105 can be rotated to loosen the connection between the door lock body 2 and the positioning base 1, allowing the door lock body 2 to be removed from the positioning base 1 independently. The door lock body 2 is disassembled from the base 1 and repaired. After repair, the door lock body 2 can be quickly positioned back onto the positioning base 1 and reinstalled. This completes the use of a modular, quick-installation electro-permanent magnet door lock device.
