[0027] like Figure 1-5As shown, the utility model discloses an electrical panel handle lock, including a lock belt 1, a fixed base 2, a moving block 3 and a lock 4. The lock belt 1 is provided with a plurality of fixing holes 11, one end of the lock belt 1 is provided on the fixed base 2, and the fixed base 2 is provided with a sliding channel 21 for the lock belt 1 to pass through. The lock 4 is provided on the fixed base 2, and the fixed base 2 is provided with a connecting port 22 opposite to the lock 4, and the connecting port 22 extends to be connected with the sliding channel 21. The lock 4 drives the moving block 3 to move at the linkage port, so that the moving block 3 has a fixed state in the sliding channel 21 and a state not in the sliding channel. When the lock is unlocked, the lock 4 drives the movable block 3 to exit the sliding channel 21, and the lock belt 1 can be freely withdrawn. The integrated lock 4 directly drives the movable block 3 to engage with the lock belt 1, completely eliminating the need for an external padlock and realizing fast one-handed operation. The mechanical interlocking between the movable block 3 and the fixed hole 11 ensures the locking reliability and prevents unauthorized operation of the handle.
[0028] The moving block 3 is provided with a guide ring 31 and the height of the guide ring 31 gradually decreases along the circumferential direction. The lock 4 is provided with a matching ring groove 421 that matches the guide ring 31 and constitutes the vertical movement of the moving block 3. When the lock 4 is rotated, the matching ring groove 421 at the bottom of the linkage disk 42 slides along the guide ring 31 of the moving block 3; due to the gradual change in the height of the guide ring 31, the rotational motion is converted into the vertical lifting and lowering of the moving block 3, so that the moving block 3 is inserted into or exits the sliding channel 21, and the rotational action is converted into a precise vertical locking motion, with a compact structure and efficient transmission; the matching ring groove 421 cooperates with the guide ring 31 to eliminate lateral offset, improve the positioning accuracy of the moving block 3, and extend the life of the components.
[0029] The guide ring 31 is provided with a sliding notch 32 arranged vertically, and the lock 4 is provided with a matching notch 422 opposite to the sliding notch 32. A fixed spring 5 is provided between the lock 4 and the moving block 3. When the guide ring 31 is opposite to the matching notch 422, the fixed spring 5 drives the moving block 3 to move in the direction of the connecting port 22. When unlocking, the lock 4 is rotated until the sliding notch 32 is aligned with the matching notch 422. At this time, under the action of the guide ring 31 and the matching ring groove 421, the moving block 3 is moved out of the sliding channel 21; when locking, the lock 4 is rotated in the opposite direction. When the guide ring 31 is opposite to the matching notch 422, the moving block 3 is inserted into the corresponding fixed hole 11 under the drive of the fixed spring 5.
[0030] A one-way inclined surface 33 with a gradually increasing cross-sectional area along the sliding channel 21 is provided at the bottom of the movable block 3. When the lock belt 1 is tightened, the one-way inclined surface 33 allows the fixing hole 11 to slide unidirectionally through the bottom of the movable block 3, realizing "one-way ratchet-type" pre-tightening. During installation, the lock belt 1 can be tightened with one hand without additional fixation.
[0031] The lock 4 includes a lock body 41 and a linkage disk 42. The matching ring groove 421 and the matching notch 422 are arranged at the bottom of the linkage disk 42. A linkage groove 423 is arranged on the top of the linkage disk 42. A linkage block 411 opposite to the linkage groove 423 is arranged on the lock body 41. When the key rotates the lock body 41, the linkage block 411 drives the linkage disk 42 to rotate, and drives the moving block 3 to rise and fall through the bottom ring groove; the linkage disk 42 can be disassembled independently.
[0032] It also includes a fixing plate 6, which is provided with a fixing channel 61 for the locking tape 1 to pass through. An adhesive tape portion 62 is provided at the bottom of the fixing plate 6. The free end of the locking tape 1 passes through the fixing channel 61 of the fixing plate 6 and is adhered to any position of the panel through the bottom adhesive tape to form a second fixing point.
[0033] It also includes a mating clip 7, on which a mating channel 71 is provided for the lock belt 1 to pass through. The mating clip 7 is also provided with a mating hole 72 that is compatible with the fixing hole 11, and the mating holes 72 are arranged through the mating clip 7. The mating clip 7 is stuck in the middle of the lock belt 1, and its mating hole 72 is aligned with the fixing hole 11 of the lock belt 1. The external padlock is locked through the mating hole 72, which is compatible with the existing external padlock requirements. The padlock can be added at any position through the mating clip 7; it does not interfere with the main lock function and provides flexible security level selection.
[0034] Working process: the lock belt 1 is wrapped around the handle of the electrical panel and passes through the sliding channel 21 of the fixed base 2. The lock 4 drives the moving block 3 to enter the sliding channel 21 through the connecting port 22 and insert into the fixed hole 11 of the lock belt 1 to achieve locking. When unlocking, the lock 4 drives the moving block 3 to exit the sliding channel 21 to release the lock belt 1; the moving block 3 cooperates with the matching ring groove 421 of the lock 4 through the bottom guide ring 31, converting the rotation of the lock 4 into vertical movement. When it rotates until the sliding notch 32 is aligned with the matching notch 422, the guide ring 31 is locked. Under the action of the annular channel 31 and the matching annular groove 421, the bottom of the moving block 3 is just in the sliding channel 21. When the lock belt 1 is tightened, the one-way inclined surface 33 at the bottom of the moving block 3 allows one-way sliding; the linkage disk 42 of the lock 4 drives the moving block 3 to rise and fall through the linkage groove 423 and the lock body 41. The free end of the lock belt 1 can pass through the fixed channel 61 of the fixed disk 6 and be fixed by the adhesive tape part 62, or be positioned by the matching channel 71 of the matching clip 7 and locked with the fixing hole 11 through the matching hole 72 through the external lock.
