Abstract
Description
Technical Field
[0001] This utility model relates to the field of hazardous chemical management technology, and in particular to a mechanical 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. Traditionally, some locks secure the cabinet from a single point, necessitating high strength and a sophisticated, complex internal structure. However, the corrosive nature of hazardous chemicals can easily damage this intricate structure, rendering the lock unusable and causing problems with retrieval. Other locks secure the cabinet from multiple points, using a separate lock for each point or adding a transmission mechanism to the locks. While this method allows for multiple locking points with a single power output, it simplifies the lock structure and complicates the overall cabinet design, making maintenance difficult. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a mechanical lock that can reduce costs, simplify the internal structure of the lock, and facilitate maintenance.
[0005] This utility model provides a mechanical lock, including: a shell, a lock cylinder, a transmission structure, and at least two lock tongue structures;
[0006] The lock cylinder is mounted on the housing; the transmission structure is connected to the lock cylinder and is located within the housing; at least one of the latch structures moves laterally relative to the housing, and at least one of the latch structures moves vertically relative to the housing. The transmission structure is connected to each latch structure and drives all latch structures to move synchronously. Each latch structure can extend out of the housing. By using the lock cylinder to drive the transmission structure, the two latch structures are simultaneously driven to translate, thus controlling the locking of two positions from a single power source. The movement directions of the two latch structures are vertical and lateral, respectively, thereby better locking the hazardous chemical container, improving the explosion-proof strength of the hazardous chemical container, and the structure is simple and easy to maintain.
[0007] In one embodiment, each of the latch structures includes: a movable latch and a transmission part;
[0008] The movable locking tongue is slidably installed inside the housing and can extend out of the housing. The transmission part is fixedly installed on the movable locking tongue and is connected to the transmission structure for transmission.
[0009] In one embodiment, at least one of the latch structures includes: a mounting groove and a magnetic element;
[0010] The mounting groove is formed on the movable latch and located at the part of the movable latch that can extend out of the housing. The magnetic component is installed in the mounting groove. By adding a magnetic component to any part of the movable latch that can extend out of the housing, it can be used with a sensor or similar device for intelligent detection. The detection structure can determine whether the movable latch has moved into place, thus completely locking the hazardous chemical cabinet.
[0011] In one embodiment, the movable latch structure that moves laterally relative to the housing is provided with the mounting groove, and the mounting groove is provided with the magnetic element. In this solution, the movable latch in the laterally moving latch structure is provided with a magnetic element, thereby completing the connection with the intelligent monitoring system. Alternatively, the magnetic element can be provided on the vertically moving latch structure, or on both moving latches in both directions, making detection more convenient and improving the explosion-proof strength of the hazardous chemical container.
[0012] In one embodiment, the transmission structure includes a driving gear and a driven gear meshing with the driving gear. The driving gear is fixedly connected to the rotatable part of the lock cylinder. The movable latch is integrally formed with the transmission part, which is a rack. The rack meshes with the driven gear. When the lock cylinder is used to unlock or lock, the driving gear can be driven to rotate, thereby the driven gear drives the rack to move, thus completing the unlocking or locking. This allows the two movable latches to move synchronously, making it convenient to open and close the lock.
[0013] In one embodiment, the driven gear includes a first driven gear and a second driven gear. The first driven gear meshes with both the driving gear and the transmission part of the latch structure that moves laterally relative to the housing. A fixed shaft is fixedly mounted on the first driven gear, and the second driven gear is fixedly mounted on the fixed shaft and meshes with the transmission part of the latch structure that moves vertically relative to the housing. The fixed shaft is rotatably mounted on the housing. By using two driven gears, the first driven gear and the second driven gear can respectively drive the laterally moving latch and the vertically moving latch, and there will be no interference due to the positional difference during the movement.
[0014] In one embodiment, there are two locking tongue structures that move vertically relative to the housing. The locking tongues of the two locking tongue structures are arranged along the vertical direction of the housing and move in opposite directions. In this solution, two vertically moving locking tongues are provided, which are divided into upper and lower locking tongues. Both can be driven by the second driven gear, so that the upper and lower positions of the hazardous chemical cabinet can be locked respectively without interfering with the horizontally moving locking tongue, thereby further improving the explosion-proof strength of the hazardous chemical cabinet.
[0015] In one embodiment, both the transmission structure and the locking tongue structure are made of stainless steel. By using stainless steel, the entire structure will not be damaged by corrosive gases emitted by hazardous chemicals, thus extending its service life and improving its explosion-proof strength.
[0016] This utility model also provides a hazardous chemical cabinet, including: a cabinet body, a door body, and a mechanical lock as described in any one of the above, wherein the door body is rotatably connected to the cabinet body; and the mechanical lock is disposed on the door body.
[0017] Therefore, this utility model has the following advantages compared with the prior art:
[0018] 1. The mechanical lock and hazardous chemical cabinet involved in this utility model utilize the lock cylinder to drive the transmission structure to simultaneously drive the two locking tongue structures to move horizontally. Thus, starting from one power source, the locking of two positions is controlled. The movement directions of the two locking tongue structures are vertical and horizontal, respectively, thereby better locking the hazardous chemical cabinet, improving the explosion-proof strength of the hazardous chemical cabinet, and the structure is simple and easy to maintain.
[0019] 2. According to the mechanical lock and hazardous chemical cabinet involved in this utility model, by adding a magnetic component to any part of the movable lock tongue that can extend out of the housing, it can be used with a sensor-like device for intelligent detection. The detection structure determines whether the movable lock tongue has moved into place, and the hazardous chemical cabinet can be completely locked.
[0020] 3. According to the mechanical lock and hazardous chemical cabinet involved in this utility model, by adding a magnetic component to the movable lock tongue in the horizontally moving lock tongue structure, the connection with the intelligent monitoring system can be completed. Alternatively, a magnetic component can be added to the vertically moving lock tongue structure, or both moving lock tongues in both directions can be added, making detection more convenient and improving the explosion-proof strength of the hazardous chemical cabinet. In this solution, two vertically moving lock tongues are provided, namely the top and bottom lock tongues, both of which can be driven by the second driven gear. Thus, without interfering with the horizontally moving lock tongues, they can lock the upper and lower positions of the hazardous chemical cabinet respectively, further improving the explosion-proof strength of the hazardous chemical cabinet. By using stainless steel material, the whole structure will not be damaged by corrosive gases emitted by hazardous chemicals, extending the service life and improving the explosion-proof strength.
[0021] 4. According to the mechanical lock and hazardous chemical cabinet involved in this utility model, when the lock cylinder is used to unlock or lock, the driving gear can be driven to rotate, thereby driving the rack to move, thus completing the unlocking or locking. The two moving bolts move synchronously, making it convenient to open and close the lock. By using two driven gears, the first driven gear and the second driven gear can drive the horizontally moving moving bolt and the vertically moving moving bolt respectively, and there will be no interference due to the position difference during the movement.

[0036] See Figure 1-2 This utility model provides a mechanical lock and a hazardous materials cabinet, including a housing 10, a lock cylinder 11, a transmission structure 12, and at least two locking tongue structures 13; the lock cylinder 11 is disposed on the housing 10; the transmission structure 12 is connected to the lock cylinder 11 and disposed inside the housing 10; at least one locking tongue structure 13 moves laterally relative to the housing 10, and at least one locking tongue structure 13 moves vertically relative to the housing 10; the transmission structure 12 is connected to each locking tongue structure 13 and drives all locking tongue structures 13 to move synchronously, and each locking tongue structure 13 can extend out of the housing 10.
[0037] Understandably, by using the lock cylinder 11 to drive the transmission structure 12 to simultaneously drive the two locking tongue structures 13 to move, the locking of two positions is controlled from one power source. The movement directions of the two locking tongue structures 13 are vertical and horizontal, respectively, which better locks the hazardous chemical cabinet, improves the explosion-proof strength of the hazardous chemical cabinet, and has a simple structure that is easy to maintain.
[0038] Combination Figure 2-3 As shown, each locking tongue structure 13 includes: a movable locking tongue 131 and a transmission part 132; the movable locking tongue 131 is slidably installed in the housing 10 and can extend out of the housing 10, and the transmission part 132 is fixedly installed on the movable locking tongue 131 and is connected to the transmission structure 12 for transmission.
[0039] Combination Figure 2-3 As shown, at least one latch structure 13 includes: a mounting groove 133 and a magnetic element 134; the mounting groove 133 is formed on the movable latch 131 and is located at the part of the movable latch 131 that can extend out of the housing 10; the magnetic element 134 is installed in the mounting groove 133; after adding the magnetic element 134 to the part of any movable latch 131 that can extend out of the housing 10.
[0040] Understandably, it can work with sensors and similar devices to perform intelligent detection, determining from the detection structure whether the movable locking tongue 131 has moved into place, thus completely locking the hazardous materials container.
[0041] Combination Figure 2-3As shown, the movable lock tongue 131 is provided with a mounting groove 133 on the lock tongue structure 13 that moves laterally relative to the housing 10, and a magnetic element 134 is provided in the mounting groove 133.
[0042] Understandably, in this solution, a magnetic component 134 is added to the movable latch 131 in the horizontally moving latch structure 13 to complete the connection with the intelligent monitoring system. Alternatively, a magnetic component 134 can be added to the vertically moving latch structure 13, or to both movable latches 131 in both directions, making detection more convenient and improving the explosion-proof strength of the hazardous chemical container.
[0043] Combination Figure 2-3 As shown, the transmission structure 12 includes a drive gear 121 and a driven gear 122 that meshes with the drive gear 121. The drive gear 121 is fixedly connected to the rotatable part of the lock cylinder 11. The movable lock tongue 131 is integrally formed with the transmission part 132. The transmission part 132 is a rack and pinion, which meshes with the driven gear 122.
[0044] Understandably, when the lock cylinder 11 is used to unlock or lock, it can drive the drive gear 121 to rotate, thereby driving the driven gear 122 to move the rack, thus completing the unlocking or locking, and allowing the two moving bolts 131 to move synchronously, making it convenient to open and close the lock.
[0045] Combination Figure 2-3 As shown, the driven gear 122 includes a first driven gear 1221 and a second driven gear 1222. The first driven gear 1221 meshes with both the driving gear 121 and the transmission part 132 of the latch structure 13, which moves laterally relative to the housing 10. A fixed shaft 1223 is fixedly mounted on the first driven gear 1221. The second driven gear 1222 is fixedly mounted on the fixed shaft 1223 and meshes with the transmission part 132 of the latch structure 13, which moves vertically relative to the housing 10. The fixed shaft 1223 is rotatably mounted on the housing 10.
[0046] Understandably, by using two driven gears 122, the first driven gear 1221 and the second driven gear 1222 can respectively drive the horizontally moving movable latch 131 and the vertically moving movable latch 131, and there will be no interference due to the position difference during the movement.
[0047] Combination Figure 2-3 As shown, there are two locking tongue structures 13 that move vertically relative to the housing 10. The locking tongues of the two locking tongue structures 13 are arranged along the vertical direction of the housing 10 and move in opposite directions.
[0048] Understandably, this solution has two vertically moving locking tongues 131, namely the top and bottom locking tongues, both of which can be driven by the second driven gear 1222. Thus, without interfering with the horizontally moving locking tongues 131, they can lock the upper and lower positions of the hazardous chemical cabinet respectively, further improving the explosion-proof strength of the hazardous chemical cabinet.
[0049] Combination Figure 1-3 As shown, both the transmission structure 12 and the locking tongue structure 13 are made of stainless steel.
[0050] Understandably, by using stainless steel in its construction, the entire structure is protected from damage by corrosive gases emitted by hazardous chemicals, extending its service life while improving its explosion-proof strength.

[0052] The working principle of this mechanical lock is as follows: When it is necessary to unlock or lock the door, the key is inserted into the lock cylinder and the lock cylinder is turned, which causes the drive gear 121 to rotate, driving the first driven gear 1221 to rotate. In turn, the first driven gear 1221 drives the horizontally moving transmission part 132 to move, causing the movable lock tongue 131 to extend or retract into the housing 10. At this time, the sensor is used to determine whether the movement of the movable lock tongue 131 is in place. When the first driven gear 1221 rotates, the fixed shaft 1223 rotates, causing the second driven gear 1222 to rotate, driving the two vertically moving movable lock tongues 131 to move simultaneously, so that the two vertically moving movable lock tongues 131 extend or retract into the housing 10 to unlock or lock the door.
[0053] 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.
[0054] 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.
