Description

Technical Field

[0001] This invention relates to the field of building decoration, and specifically to a method for installing and using a magnetic door bolt. Background Technology

[0002] Nowadays, most residential buildings use security doors that are burglarproof and fireproof for the entrance doors; in order to facilitate the movement of furniture, the security doors are often made into double doors, which has become a standard feature of many residential buildings.

[0003] Security doors are made by clamping fire-resistant material between two stamped metal plates and fixing them together to form a complete door leaf. Security doors are usually equipped with anti-theft locks as standard. Because the anti-theft locks already have anti-theft and internal deadbolt functions, security doors usually do not have indoor bolts.

[0004] However, there are always skilled thieves who can use special methods and special key tools to open well-locked security locks. Especially after videos of combination locks being opened with electronic master keys were exposed, people are always a little apprehensive when they are indoors, always worried that their personal safety is not guaranteed.

[0005] The best way to solve this problem is to install a door bolt. However, installing a door bolt usually requires screws to be installed on the door leaf to secure it. When installing a door bolt on a metal door, self-tapping screws are used to secure it.

[0006] Typically, the sheet metal on the inside side of a security door is relatively thin, and self-tapping screws have limited grip on the sheet metal. When there is a violent impact, the self-tapping screws are prone to loosening and falling off. If it is a rented house, the landlord usually does not agree to drill holes in the security door to install bolts. If the tenant installs them privately, he / she may be liable for the cost of restoring the door. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a method for installing and using a magnetic door bolt.

[0008] A method for installing and using a magnetic door bolt, characterized by comprising the following steps:

[0009] Step 1, Preparation:

[0010] 1) Confirm that the security door to which the bolt is to be installed is a burglarproof double door made of stamped metal sheet;

[0011] 2) Confirm that the door can be attracted by a magnet;

[0012] Step two, install door bolts on the inward-opening door:

[0013] In this step, the second magnetic metal door leaf represents the main door leaf that opens inward, and the first magnetic metal door leaf represents the door leaf that is normally locked and not opened.

[0014] 1) Move the positioning head and retract it completely into the limit groove;

[0015] 2) Tear off the protective film on the double-sided tape under the plug head;

[0016] 3) Close the second magnetic metal door;

[0017] 4) Place a card approximately 1mm thick against the edge of the second magnetic metal door leaf where the bolt will be installed;

[0018] 5) Tilt the card approximately 10 degrees toward the second magnetic metal door leaf;

[0019] Place the side of the bolt head with the opening against the card, and bring the bottom side of the bolt head with the magnet close to the first magnetic metal door leaf;

[0020] 6) Adjust the bolt head to a suitable height for convenient use;

[0021] 7) Grasp the end of the bolt and bring the bolt head close to the card. Slowly move the end of the bolt towards the first magnetic metal door leaf until the magnet completely attracts the first magnetic metal door leaf. Firmly attract and stick the bolt head to the first magnetic metal door leaf.

[0022] 8) Confirm that the second magnetic metal door leaf does not come into contact with the latch when opening or closing;

[0023] 9) Close the second magnetic metal door leaf, move the positioning head as far as possible beyond the limiting groove, and rotate the adjusting pin so that the head of the adjusting pin just touches the closed second magnetic metal door leaf;

[0024] 10) Rotate the adjusting pin half a turn in the opposite direction to ensure that the positioning head does not contact the second magnetic metal door leaf when moving back and forth. Installation is complete.

[0025] Step 3: Install door bolts on the outward-opening door panels:

[0026] In this step, the first magnetic metal door leaf represents the door leaf that opens outwards, and the second magnetic metal door leaf represents the fixed door leaf that is normally locked and not opened.

[0027] 1) Move the positioning head and retract it completely into the limit groove;

[0028] 2) Tear off the protective film on the double-sided tape under the plug head;

[0029] 3) Close the first magnetic metal door;

[0030] 4) Place a card approximately 1mm thick against the edge of the second magnetic metal door leaf where the bolt will be installed;

[0031] 5) Tilt the card approximately 10 degrees toward the second magnetic metal door leaf;

[0032] Place the side of the bolt head with the opening against the card, and bring the bottom side of the bolt head with the magnet close to the first magnetic metal door leaf;

[0033] 6) Adjust the bolt head to a suitable height for convenient use;

[0034] 7) Grasp the end of the bolt and bring the bolt head close to the card. Slowly move the end of the bolt towards the first magnetic metal door leaf until the magnet completely attracts the first magnetic metal door leaf. Firmly attract and stick the bolt head to the first magnetic metal door leaf.

[0035] 8) Confirm that the first magnetic metal door leaf does not come into contact with the bolt head when it is opened or closed;

[0036] 9) Close the first magnetic metal door leaf, move the positioning head and extend it as far as possible out of the limiting groove, and rotate the adjusting pin so that the head of the adjusting pin just contacts the second magnetic metal door leaf;

[0037] 10) Rotate the adjusting pin half a turn in the opposite direction to ensure that the positioning head does not contact the second magnetic metal door leaf when moving back and forth. Installation is complete.

[0038] Step 4, Demolition:

[0039] 1) Clamp the end of the bolt with pliers;

[0040] 2) Pull the bolt tail away from the magnetic metal door leaf, so that the base rotates around the bottom edge of the bolt head's outer surface as the center, making the angle between the bottom surface of the magnet block and the magnetic metal door leaf larger. The attraction of the magnet block to the magnetic metal door leaf will gradually weaken, and the double-sided tape will gradually detach from the magnetic metal door leaf.

[0041] 3) The base rotates around the bottom edge of the bolt head's outer facade. After the angle between the bottom surface of the base and the magnetic metal door leaf is greater than 4 degrees, the bolt can be removed.

[0042] 4) Remove any remaining adhesive from the magnetic metal door panel. Removal complete.

[0043] Option 1, as the preferred option among the basic options, uses non-magnetic materials for the entire door bolt, except for the magnet.

[0044] Preferred Option 2, as a preferred option of Preferred Option 1, uses a strong magnet. When the magnet is attached to the first magnetic metal door leaf, the vertical attraction between the magnet and the first magnetic metal door leaf is greater than 60 kg.

[0045] Preferred option three, as a preferred option two, involves two magnet blocks, with the bottom surface of the magnet blocks aligned with the surface of the magnet blocks.

[0046] The bottom surfaces of the plug heads are on the same plane;

[0047] The preferred option four, which is a preferred option three, allows the handle to be pushed by an external force, enabling the slider to slide back and forth in the inner cavity, and the positioning head to be moved and retracted into the fully limiting groove.

[0048] Option 5, as a preferred option of the basic option or the preferred option 4, allows the adjusting pin on the positioning head to adjust the length of the pin head exposed below the positioning head.

[0049] Option 6, as a preferred option of the basic option or the preferred option 5, uses high-viscosity self-adhesive double-sided tape.

[0050] The advantages of the above technical solution are as follows: The magnet on the bolt allows for seamless installation directly onto magnetic metal doors without drilling holes, reducing installation precision requirements and making installation quick and convenient; the magnet presses down on the double-sided adhesive, increasing its adhesion and providing the bolt with a dual reinforcement of adhesion and magnetism for stability; even if the door is subjected to sudden external force that may loosen the double-sided adhesive under the magnet, the magnet's attraction to the door will press the adhesive back into its original tight state once the force disappears, automatically restoring the bolt's stability; installation is particularly convenient on magnetic metal double doors.
