Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical management technology, and in particular to a mechanical electronic lock and a hazardous chemical cabinet. Background Technology

[0002] In the field of hazardous chemicals management, hazardous chemical storage cabinets are a very important piece of equipment, and the locks on the cabinets are key to their management.

[0003] Hazardous chemicals often exhibit volatility during storage. These volatile chemicals are corrosive and flammable, requiring locks with sufficient strength for safekeeping. Traditional electronic locks typically contain circuit boards and other electronic components that are highly susceptible to corrosion and electrical sparks upon contact with the volatile chemicals. This damage can render the lock unusable or even prevent the cabinet door from opening, significantly increasing the difficulty of managing hazardous chemicals. Current technology does not readily incorporate an emergency unlocking mechanism while protecting the circuit board. Most emergency unlocking mechanisms are somewhat destructive and require replacement as the electronic lock deteriorates. Furthermore, it is difficult to achieve structural complementarity between electronic and mechanical locks, hindering the optimization of the overall electronic lock structure. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a mechanical electronic lock that can be mechanically unlocked in an emergency after the circuit of the electronic lock is damaged.

The mechanical lock structure is disposed within the housing and includes a limiting mechanism and an unlocking mechanism. The unlocking mechanism is movably disposed within the housing and connected to the latch. The limiting mechanism has a locking state where it engages the unlocking mechanism and an unlocking state where it disengages from the unlocking mechanism. By utilizing the unlocking mechanism, an emergency unlocking function can be performed when the electromagnetic lock structure is not working. By utilizing the limiting mechanism, a locking function can be performed when the electromagnetic lock structure is working. This simplifies the structure of traditional locks and combines mechanical and intelligent control, avoiding the destructive problems of conventional emergency locks.

[0013] In one embodiment, the reset assembly includes: a fixing member, a connecting member, and a reset spring;

[0014] The fixing component is fixedly installed inside the outer shell, the connecting component is fixedly installed on the unlocking component, one end of the return spring abuts against the fixing component, and the other end abuts against the connecting component.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0035] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0040] See Figure 1 This utility model provides a mechanical-electronic lock and a hazardous materials cabinet, including a shell 10, a locking tongue 11, an electromagnetic lock structure 12, and a mechanical lock structure 13. The locking tongue 11 is disposed inside the shell 10. The electromagnetic lock structure 12 is disposed inside the shell 10 to drive the locking tongue 11 to move. The mechanical lock structure 13 is disposed inside the shell 10 and includes a limiting mechanism 131 and an unlocking mechanism 132. The unlocking mechanism 132 is movably disposed inside the shell 10 and connected to the locking tongue 11. The limiting mechanism 131 has a locking state of engaging the unlocking mechanism 132 and an unlocking state of disengaging from the unlocking mechanism 132.

[0041] Understandably, by using the unlocking mechanism 132 to perform emergency unlocking when the electromagnetic lock structure 12 is not working, and by using the limiting mechanism 131 to prevent locking when the electromagnetic lock structure 12 is working, the structure of traditional locks is simplified, and mechanical and intelligent control are combined, avoiding the destructive problems of conventional emergency locks.

[0042] Combination Figure 1 and Figure 2 As shown, the limiting mechanism 131 includes a lock cylinder assembly 1311 and a limiting part 1312. The lock cylinder assembly 1311 is mounted on the housing 10. The limiting part 1312 is rotatably disposed on the lock cylinder assembly 1311. In the locked state, the limiting part 1312 is engaged with the unlocking mechanism 132.

[0043] Understandably, by controlling the rotation of the limiting part 1312 through the lock cylinder assembly 1311, the purpose of restricting the unlocking mechanism 132 from opening when the electromagnetic lock structure 12 is working is achieved. In use, the lock cylinder in the lock cylinder assembly 1311 can be rotated by using a key, thereby achieving the purpose of unlocking or locking with a simple structure.

[0044] Combination Figure 2 and Figure 3As shown, the unlocking mechanism 132 includes: an unlocking component 1321, a connecting component 1322, an opening 1323, and a reset component 100. The unlocking component 1321 is slidably installed inside the housing 10 and located below the lock cylinder assembly 1311. The unlocking component 1321 has a protruding locking portion so that in the locked state, the locking portion is locked to the limiting portion 1312. The connecting component 1322 is slidably installed inside the housing 10. One end of the connecting component 1322 is fixedly connected to the lock tongue 11, and the other end can abut against the unlocking component 1321. The opening 1323 is opened on the housing 10 and is opposite to the end of the unlocking component 1321 away from the connecting component 1322. The reset component 100 is disposed inside the housing 10 and located on the movement path of the unlocking component 1321.

[0045] Understandably, after the limiting part 1312 is opened, the limiting part 1312 no longer restricts the locking part 1321. The rod passes through the opening 1323 and extends into the housing 10 to push the locking part 1321 to move. This drives the connecting part 1322 to move the bolt 11, thereby completing the unlocking. With the reset component 100 resetting after unlocking, the purpose of emergency unlocking is achieved without damaging the original structure.

[0046] Combination Figure 1-4 As shown, the unlocking component 1321 has an unlocking end and a connecting end. The connecting end is fixedly connected to the connecting component 1322, and the axis of the unlocking end is aligned with the axis of the opening 1323.

[0047] Combination Figure 1-4 As shown, the unlocking mechanism 132 also includes a sensor 1324, which is disposed on the housing 10 and located between the opening 1323 and the unlocking member 1321, for detecting the position of the unlocking member 1321.

[0048] Understandably, by using sensor 1324 to detect the position of unlocking component 1321, the purpose of intelligent control can be achieved. This eliminates the need for manual inspection of whether the hazardous materials container is locked, as sensor 1324 can be used to detect whether unlocking component 1321 is in place.

[0049] Combination Figure 1-4 As shown, the reset assembly 100 includes: a fixing member 101, a connecting member 102, and a reset spring 103. The fixing member 101 is fixedly disposed inside the housing 10, the connecting member 102 is fixedly disposed on the unlocking member 1321, and one end of the reset spring 103 abuts against the fixing member 101 and the other end abuts against the connecting member 102.

[0050] Understandably, by utilizing the integral molding of the connector 102 and the unlocking component 1321, the connection of the connector 102 is made more stable, and the return spring 103 can better drive the unlocking component 1321 to return to its original position.

[0051] Combination Figure 1-4 As shown, the electromagnetic lock structure 12 includes an electromagnetic lock 121 and a control device 122. The electromagnetic lock 121 is disposed in the housing 10 for driving the bolt 11 to move. The control device 122 is electrically connected to the electromagnetic lock 121 and is connected to the sensor 1324.

[0052] Combination Figure 1-4 As shown, the controller 122 includes a circuit board and an insulating layer. The insulating layer covers the circuit board, the circuit board is fixed to the housing 10 and electrically connected to the electromagnetic lock 121, the circuit board is connected to the sensor 1324, and the insulating layer is an adhesive layer formed by a potting process.

[0053] Understandably, by applying potting compound to the outer layer of the circuit board, the circuit board is sealed. The electromagnetic coil in the electromagnetic lock 121 is also sealed with potting compound, further isolating the corrosive gases inside the hazardous materials cabinet, protecting the circuit board, and thus reducing damage to the electronic lock.

[0054] Combination Figure 1-4 As shown, the outer shell 10, the latch 11, the electromagnetic lock structure 12 and the mechanical lock structure 13 are all made of stainless steel, and a layer of titanium alloy is electroplated on the surface of the above components.

[0055] Understandably, by electroplating a titanium alloy layer onto the stainless steel surface, the overall explosion-proof strength is improved while reducing the rate of corrosion and extending the service life.

[0056] This utility model also provides a hazardous chemical cabinet, including: a cabinet body and a door body and a mechanical lock of any one of the above, wherein the door body is rotatably connected to the cabinet body; and a mechanical electronic lock is provided on the door body.

[0057] The working principle of this electromechanical lock is as follows: When in normal use, it is opened and closed by the electromagnetic lock structure 12. When the electromagnetic lock structure 12 is not working, the key is first inserted into the lock cylinder assembly 1311 and then rotated, causing the limiting part 1312 to be driven, thereby disengaging the limiting part 1312 from the locking part. Then, the rod is passed through the opening 1323 and inserted into the outer shell 10, pushing the unlocking part 1321 and compressing the return spring 103. At this time, the unlocking part 1321 is disengaged from the sensor 1324, driving the connecting part 1322, thereby moving the bolt 11. After unlocking, the rod is pulled out, and then the return spring 103 is reset, driving the unlocking part 1321 to move, and it is sensed again by the sensor 1324, causing the lock cylinder assembly 1311 to reverse, thereby limiting the movement of the unlocking part 1321 again by the limiting part 1312.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
