Description

Technical Field

[0001] The utility model relates to a circuit breaker lock, in particular to a circuit breaker lock with a lock. Background Art

[0002] A circuit breaker lock is an electrical protection device, and more particularly, relates to a lock for preventing a circuit breaker from being misoperated. A circuit breaker is a switching device that can close, carry and disconnect current under normal circuit conditions, and can close, carry and disconnect current under abnormal circuit conditions within a specified time.

[0003] A circuit breaker generally includes a shell, components inside the shell, and a handle extending out of the shell surface at the end, wherein the handle is located in a shell groove on the shell surface. The operator can open and close the circuit breaker by moving the handle up and down, so the circuit breaker lock enters the shell groove. The circuit breaker lock is fixed relative to the handle and at the same time abuts against the shell groove, forming a handle that is not centered, ensuring that the circuit breaker state will not change, thereby preventing the circuit breaker from being operated incorrectly.

[0004] Currently, after the circuit breaker lock fixes the handle, an additional lock is required to fix the circuit breaker, which makes the installation complicated. Utility Model Content

[0009] By adopting the above technical solution, when the cover body and the lock body need to be fixed, the cover body is first rotated to a suitable position, and then the key is inserted into the lock hole, thereby driving the blocking member to rotate through the lock, so that the blocking member rotates to the blocking position. At this time, the blocking member and the linkage block are abutted against each other, thereby fixing the cover body and the lock body.

[0010] The utility model is further configured as follows: a rotating block is provided on the lock body, a rotating hole is provided on the rotating block, a rotating shaft that rotates with the rotating hole is provided on the cover body, the rotating hole and the rotating shaft constitute a hinge between the cover body and the lock body, and the linkage block is located on the rotating block and rotates synchronously with the rotating block.

[0011] By adopting the above technical solution, when the lock body rotates relative to the cover body, the linkage block will be driven to rotate together. When the linkage block is blocked by the blocking member, the lock body is fixed.

[0012] The utility model is further configured as follows: the blocking member includes a matching block and a blocking block, the matching block is provided with a matching groove, the lock is provided with an auxiliary block located in the matching groove and constitutes the lock to drive the matching block, and the blocking block is arranged on the other side of the matching block relative to the matching groove.

[0013] The utility model is further configured as follows: it also includes a threaded rod, a fixing groove engaged with the circuit breaker is provided in the lock body, a threaded groove is also provided in the lock body and the threaded groove extends to communicate with the fixing groove, the threaded rod is threadedly matched in the threaded rod, and the threaded rod constitutes the lock body to fix the handle.

[0014] By adopting the above technical solution, when the circuit breaker does not need to be operated, the fixing groove is aligned with the handle of the circuit breaker and inserted, and then the threaded rod is rotated so that the threaded rod part passes through the threaded hole into the fixing groove and abuts against the handle, thereby fixing the handle.

[0015] The utility model is further configured as follows: a receiving cavity is further provided in the cover body, and when the blocking member is located at the blocking position, the threaded rod is located in the receiving cavity.

[0016] By adopting the above technical solution, when it is necessary to fix the cover body and the lock body, the cover body is first rotated so that the accommodating cavity of the cover body covers the threaded rod, thereby preventing the outside from operating the threaded rod, and then the cover body and the lock body are fixed. At this time, if there is no key, the blocking member cannot be rotated, and then the cover body and the lock body cannot be fixed, and there is no way to operate the threaded rod.

[0025] The cover body 2 is provided with a receiving groove 21 for accommodating the lock 3, the lock 3 is located in the receiving groove 21, one end of the lock 3 has a locking hole 31 and is located at the notch of the receiving groove 21, and a blocking member 32 is provided at the other end of the lock 3 relative to the locking hole 31. A linkage block 11 is provided on the lock body 1, and the blocking member 32 has a blocking position and a connecting position. The blocking position is that the blocking member 32 is located on the relative movement trajectory of the linkage block 11 and abuts against the linkage block 11 to constitute a fixed state of the cover body 2 and the lock body 1, and the connecting position is that the blocking member 32 is not on the relative movement trajectory of the linkage block 11, and the cover body 2 and the lock body 1 rotate in coordination. When it is necessary to fix the cover body 2 and the lock body 1, the cover body 2 is first rotated to a suitable position, and then the key is inserted into the lock hole 31, so that the blocking member 32 is driven to rotate by the lock 3, so that the blocking member 32 is rotated to the blocking position, at which time the blocking member 32 abuts against the linkage block 11, thereby constituting the fixation of the cover body 2 and the lock body 1.

[0026] A rotating block 12 is provided on the lock body 1, and a rotating hole 13 is provided on the rotating block 12. A rotating shaft 22 that rotates with the rotating hole 13 is provided on the cover body 2. The rotating hole 13 and the rotating shaft 22 constitute a hinge between the cover body 2 and the lock body 1. The linkage block 11 is located on the rotating block 12 and rotates synchronously with the rotating block 12. When the lock body 1 rotates relative to the cover body 2, the linkage block 11 will be driven to rotate together. When the linkage block 11 is blocked by the blocking member 32, the lock body 1 is fixed.

[0027] The blocking member 32 includes a matching block 321 and a blocking block 322. The matching block 321 is provided with a matching groove 33.
