Description

Technical Field

[0001] This utility model belongs to the field of magnetic lock technology, specifically a magnetic lock suction plate anti-loosening locking structure. Background Technology

[0002] Magnetic locks are a widely used type of electronic access control lock. They use magnetic force to control the opening and closing of doors and have the advantages of easy installation, simple operation, and good anti-theft performance.

[0003] In existing technology, the suction plate is installed on the door with screws or on a matching bracket (please refer to...). Figure 6 As shown, the suction plate is made of iron. The stronger the magnetic lock model, the larger and heavier the suction plate. In previous use, it was found that with the increase in the number of times the door is opened and closed and the impact of vibration, the screws securing the suction plate will gradually loosen. When the screws completely fall off, there is a risk that the suction plate may fall and injure people. To solve this risk, a magnetic lock suction plate anti-loosening locking structure is proposed. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic locking plate anti-loosening locking structure.

[0005] The technical solution adopted by this utility model is as follows: a magnetic locking plate anti-loosening locking structure, including a suction plate installed on a door or suction plate bracket, wherein a countersunk through hole and a countersunk threaded hole are opened on the outer wall surface of the suction plate, the countersunk threaded hole is located in the outer area of ​​the countersunk through hole and one end is connected to the countersunk through hole, a locking screw and a stop screw are respectively provided in the countersunk through hole and the countersunk threaded hole, the head of the locking screw is recessed inward to form a positioning hole, and the outer edge of the head of the stop screw is adapted to engage in the positioning hole.

[0006] In a preferred embodiment, there are two positioning ports, which are symmetrically distributed at both ends of the head of the locking screw.

[0007] In a preferred embodiment, the positioning port has a semi-circular structure.

[0008] In a preferred embodiment, both the locking screw and the stop screw are countersunk screws.

[0009] In a preferred embodiment, the tail of the locking screw passes through the countersunk hole and is mounted on the door or suction plate bracket.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: a countersunk threaded hole is provided around the countersunk through hole of the suction plate and is connected to it, and a semi-circular notch is designed on the locking screw. During the assembly of the suction plate, the suction plate is first fastened to the door or suction plate bracket with the locking screw. After the position is correct, the stop screw is tightened, and the head of the stop screw is used to limit and lock the locking screw, which plays a role in preventing rotation and loosening, and can avoid the problem of the suction plate falling and injuring people.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] Reference Figure 1-6A magnetic locking plate anti-loosening locking structure includes a suction plate 100 installed on a door body 400 or a suction plate bracket 600. The outer wall of the suction plate 100 has a countersunk through hole 110 and a countersunk threaded hole 120. The countersunk threaded hole 120 is located in the peripheral area of ​​the countersunk through hole 110, and one end is connected to the countersunk through hole 110. A locking screw 200 and a locking screw 300 are respectively installed in the countersunk through hole 110 and the countersunk threaded hole 120. The head of the locking screw 200 is recessed inward to form a positioning opening 210, which is semi-circular. The outer edge of the head of the locking screw 300 is adapted to engage within the positioning opening 210. The countersunk through hole 110 has a countersunk threaded hole 120 connected to it, and a semi-circular positioning port 210 is designed on the locking screw 200. During the process of assembling the suction plate 100 onto the door body 400 or suction plate bracket 600, the suction plate 100 is first fastened to the door or suction plate bracket 600 with the locking screw 200. After the position is correct, the stop screw 300 is tightened, and the head of the stop screw 300 is used to limit and lock in the positioning port 210. This is used to limit the installation position of the locking screw 200, which can prevent the locking screw 200 from rotating and loosening, and can prevent the suction plate 100 from falling and injuring people due to the loosening of the locking screw 200.

[0026] In this embodiment, the size of the countersunk threaded hole 120 is smaller than that of the countersunk through hole 110, and the countersunk through hole 110 and the countersunk threaded hole 120 can be combined to form a gourd shape.

[0027] In this embodiment, refer to Figure 3 As shown, there are two positioning ports 210, symmetrically distributed at both ends of the head of the locking screw 200. The advantage of the symmetrical arrangement of the two positioning ports 210 is that it makes it easier to align the locking screw 200 during installation. Of course, in other embodiments, the locking screw 200 can also be designed with three or other numbers depending on its size.

[0028] Furthermore, both the locking screw 200 and the locking screw 300 are countersunk screws. The head of the countersunk screw is designed to be countersunk, so that the head of the locking screw 200 and the locking screw 300 can be embedded in the through hole 110 and the countersunk threaded hole 120 during installation, thus maintaining the flatness and aesthetics of the workpiece surface.

[0029] In this embodiment, refer to Figure 4 and Figure 5As shown, the tail of the locking screw 200 passes through the countersunk hole 110 and is installed on the door body 400 or the suction plate bracket 600. The length of the locking screw 200 is longer than the size of the countersunk hole 110. When installed on the door body 400, holes can be pre-drilled in the door body 400 for the clamping nut 500. During installation, the clamping nut is inserted into the door, and the locking screw 200 is used in conjunction with the clamping nut 500 to fasten the suction plate 100 to the door body 400. When installed on the suction plate bracket 600, threaded holes that match the locking screw 200 can be pre-drilled in the suction plate bracket 600, and the suction plate 100 can be directly fixed to the suction plate bracket 600 using the locking screw 200. Of course, washers can also be additionally fitted on the locking screw 200. It should be noted that in installation scenarios that require the use of suction plate bracket 600, because the aluminum bracket (here, suction plate bracket 600) has a limited thickness and a relatively reduced number of tapping turns, it is more likely to loosen and fall off. Therefore, it is even more necessary to add a stop screw 300 to reduce the problem of the locking screw 200 loosening and falling off.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
