Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switching electrical appliances, in particular to a circuit breaker manual operating handle with an internal padlock. Background Art
[0002] As an accessory device of a wiring circuit breaker, an operating handle is an accessory device for opening and closing the circuit breaker installed inside. In the past, a groove was provided beside the operating handle, and a handle locking device composed of spring wire was inserted into the groove to keep the operating handle of the circuit breaker in the closed or open position.
[0003] There is also a bolt structure formed by a handle cover in which a handle locking device is inserted into the operating handle and a bolt separated from the handle cover.
[0004] Either the above-mentioned locking structures are unstable in structure and cannot effectively ensure the locking of the handle, or they are too complex to use, resulting in inconvenient use; moreover, the complex structure also means its cumbersome structure and high cost. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a circuit breaker manual operating handle with an internal padlock.
[0006] The utility model has the advantages of high safety, convenient locking and low cost.
[0007] The technical solution of the utility model: A circuit breaker manual operating handle with an internal padlock includes a housing installed on the circuit breaker, a handle rotatably arranged inside the housing, and a lock core slidably arranged in the middle of the handle; a lock hole for installing an external padlock is provided at the upper part of the lock core; a limit seat corresponding to the handle is arranged inside the housing, and two stepped card slots are correspondingly distributed on the limit seat, and the stepped card slots respectively correspond to the opening point and the closing point; the stepped card slot is in a stepped shape and is provided with a limit card slot; a lock core block corresponding to the stepped card slot is arranged at the bottom of the lock core, and one end of the lock core block passes through the handle; a return spring abutting against the handle is arranged inside the lock core.
[0008] In the aforesaid circuit breaker manual operating handle with an internal padlock, the housing corresponds to the circuit breaker, installation grooves are provided on both sides of the bottom of the housing, and an installation seat corresponding to the handle protrudes outward at the top of the housing; screw connection seats for installing screws corresponding to the circuit breaker are provided at the lower parts of both ends of the housing.
[0009] In the aforesaid circuit breaker manual operating handle with an internal padlock, an installation column for clamping and installing the return spring is arranged inside the lock core.
[0010] Compared with the prior art, the utility model is provided with a handle rotatably arranged on the cover shell, and a slidable lock core is sleeved in the handle. The handle is matched with a limit seat corresponding to the lock core in the cover shell. The limit seat is provided with stepped card slots at the opening and closing points, so that the lock core can slide outwards along the gap of the stepped card slots at this position, which is convenient for the staff to directly add an external lock to the lock hole;
[0011] By setting the stepped card slots corresponding to opening and closing, when the lock core is pulled out for locking, the lock core block is limited and clamped in the stepped card slot, so as to prevent the handle from rotating and effectively prevent misoperation and other situations after locking;
[0012] The structure design of this application is simple and ingenious, the parts are concise, and the production and subsequent maintenance and replacement costs are relatively lower.
[0013] Therefore, the utility model has the advantages of high safety, convenient locking and low cost. BRIEF DESCRIPTION OF THE DRAWINGS
