Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, specifically a single-point industrial enclosure door lock. Background Technology

[0002] Traditional industrial enclosure door locks often employ multi-point locking or complex structures, which, while improving security, suffer from high costs, complex installation, and inconvenient maintenance. Especially in compact environments such as electrical control cabinets and mechanical equipment, the bulky structure of multi-point locks can occupy internal space, and frequent opening and closing can cause wear and tear on one side of the latch, leading to a decrease in protection level. Furthermore, traditional locks lack universal design, making it difficult to adapt to door panels of different thicknesses or left / right opening requirements. Single-point door locks, by simplifying the mechanical structure and achieving closure through a single locking point, offer advantages such as low cost, flexible installation, and reliable protection, making them the preferred solution for lightweight protection of industrial enclosures.

[0003] Chinese patent document CN219654483U discloses a power distribution cabinet door lock, including a mounting bolt located at the center of the right end of the lock cylinder shaft, and an axially elastically connected internal gear ring circumferentially positioned on the right end face of the lock cylinder shaft at the periphery of the mounting bolt. The aforementioned utility model, through the design of setting an internal toothed ring, mounting bolts, and an adjustable latch mechanism on the lock cylinder shaft, allows the latch mechanism to be manually pushed to the left during installation. Then, the latch mechanism is rotated and installed onto the mounting bolt by hand. The internal toothed ring is then released to engage with the toothed post of the latch mechanism, thus achieving the positioning and installation of the latch mechanism on the lock cylinder shaft. After the latch mechanism is installed, the extension length of the latch strip can be adjusted according to the structure of the distribution cabinet and the position of the cabinet door lock hole, without the need to replace the latch. This effectively improves the convenience of installation and adjustment of the latch mechanism, saving time and effort. However, the device, which only uses a handle and lock cylinder shaft, cannot prevent moisture in high humidity and rainy weather, and over time, the inside of the lock cylinder shaft will rust and corrode. Therefore, we propose a single-point industrial cabinet door lock. Utility Model Content

A locking block 92 is fixedly connected to the lower side of the front wall of the rear cavity of the housing 1, and the through groove 91 is located directly above the locking block 92. The housing 1 is fastened onto the distribution cabinet door with the installation opening. Then, the fixing plate 5 and the connecting block 6 are aligned. The fixing plate 5 is fixedly connected to the connecting block 6 by screws passing through the round holes on the fixing plate 5. This makes the fixing plate 5 and the housing 1 clamped on both sides of the inner cavity of the distribution cabinet door, thereby firmly installing the device on the distribution cabinet door.

[0017] Handle mechanism 3 includes handle body 31. A claw 32 is fixedly connected to the lower rear end of handle body 31. A rotating groove 36 is formed on the upper rear end of handle body 31. A connecting assembly 35 is rotatably connected to the inner cavity of rotating groove 36. A fixing assembly 34 is provided on the rear side of connecting assembly 35. A stop pin 33 is provided on the rear side of fixing assembly 34. A plurality of mounting holes 37 are formed at the front end of stop pin 33. The rear side of the outer surface of handle body 31 fits against the front cavity of housing 1. The outer surface of claw 32 is slidably connected to the inner cavity of through groove 91. Connecting assembly 35 includes rotating head 351. A rotating shaft 352 is fixedly connected to the rear end of rotating head 351. A mounting groove 353 is formed on the rear end of rotating shaft 352. A screw is rotatably connected to the middle of the inner cavity of mounting groove 353. The threaded shaft 355 has an auxiliary rod 354 fixedly connected to the lower side of the front wall of the inner cavity of the mounting groove 353. The outer surface of the rotating shaft 352 is rotatably connected to the inner cavity of the sleeve column 4. The front part of the outer surface of the rotating head 351 is rotatably connected to the inner cavity of the rotating groove 36. The fixing group 34 includes a T-shaped column 341. A threaded through groove 342 is opened in the middle of the front end of the T-shaped column 341. A sliding hole 343 is opened on the lower side of the middle of the front end of the T-shaped column 341. Threaded holes 344 are opened on both the left and right sides of the rear end of the T-shaped column 341. The front part of the outer surface of the T-shaped column 341 is slidably connected to the rear side of the inner cavity of the mounting groove 353.

[0018] After the device is installed, rotate the handle body 31 downwards with the connection between the rotating groove 36 and the rotating head 351 as the center. This causes the pawl 32 to insert into the cavity of the through groove 91. Simultaneously, the handle body 31 pushes the top pin 9 to compress the second spring 8, which slides within the sliding groove 7 until the pawl 32 is engaged with the locking block 92, achieving the locking purpose. When unlocking is required, insert a special key into the lock cylinder assembly 2. The lock cylinder assembly 2 causes the pawl 32 to disengage from the locking block 92, and the spring 8 pushes the top pin 9, which ejects the handle body 31. Then, rotate the handle body 31, causing the connecting assembly 35 to rotate within the cavity of the sleeve 4. This rotation of the connecting assembly 35 causes the fixing assembly 34 to rotate the stop pin 33, freeing the stop pin 33 from being engaged within the distribution cabinet cavity, allowing the cabinet door to be opened. Furthermore, according to the distribution... Depending on the type of electrical cabinet, the front-to-back and left-to-right distances of the stop pin 33 can be adjusted. A hex wrench is inserted into the threaded slot 342 and pressed against the threaded shaft 355. The threaded shaft 355 is rotated within the mounting slot 353 by the hex wrench. With the rotation of the threaded shaft 355, the threaded slot 342, and the auxiliary rod 354, the T-shaped post 341 slides back and forth within the mounting slot 353 to a suitable position, thus adjusting the front-to-back distance of the stop pin 33. Two screws are inserted into any two adjacent cavities of the mounting holes 37, and two screws are inserted into the two screw holes 344 and tightened to fix the stop pin 33 onto the T-shaped post 341, thereby adjusting the left-to-right distance of the stop pin 33. This allows the device to be used with different types of electrical cabinets, improving its practicality.

[0019] Example 2: Please see Figure 1 and Figure 7 This utility model provides a technical solution: a single-point industrial box door lock, the lock cylinder assembly 2 includes a core shell 21, the inner cavity of the core shell 21 is provided with a lock cylinder body 22, the rear side of the outer surface of the lock cylinder body 22 and the core shell 21 are provided with a swing block 28, the left side of the outer surface of the swing block 28 is fixedly connected with an L-shaped wave plate 27, the front side of the outer surface of the lock cylinder body 22 is fixedly connected with a column shell 29, the middle of the front end of the column shell 29 is provided with a key hole 24, the upper side of the front wall of the inner cavity of the column shell 29 is fixedly connected with a rotating support 26, the inner cavity of the rotating support 26 is rotatably connected with a baffle 25, the rear side of the outer surface of the rotating support 26 is sleeved and connected with a spring 23, the right end of the spring 23 is fixedly connected to the upper side of the front wall of the inner cavity of the column shell 29, the left end of the spring 23 is fixedly connected to the upper side of the rear end of the baffle 25, the front side of the outer surface of the baffle 25 fits against the inner cavity of the key hole 24, and the front side of the outer surface of the core shell 21 is fixedly connected to the lower side of the front cavity and the rear cavity of the casing 1.

[0020] In detail, when a special key is inserted into the keyhole 24, it pushes the baffle 25 to rotate around the rotating support 26 and compresses the spring 23. The key is then inserted into the lock cylinder 22 and rotated to unlock, simultaneously driving the swing block 28 to rotate. The rotation of the swing block 28 causes the L-shaped wave plate 27 to rotate against the outer surface of the core shell 21, so that the L-shaped wave plate 27 pushes against the pawl 32 during rotation, causing the pawl 32 to disengage from the pawl block 92. Then, under the action of the spring 8 and the top pin 9, the lower side of the handle body 31 pops out of the front cavity of the sleeve 1. At this time, rotating the handle body 31 can open the cabinet door. Then, when the key is pulled out, under the elastic force of the spring 23, the baffle 25 is pushed to rotate, so that the front side of the outer surface of the baffle 25 blocks the keyhole 24, preventing rainwater from entering the spring 23 cavity through the keyhole 24 and causing corrosion to the inside of the lock cylinder 22. The addition of the baffle 25 plays a role in rain protection and increases the service life of the device.
