Embodiment Construction

[0034] The three-position indication and locking device for the drawer seat of the circuit breaker provided by the specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as figure 1 As shown, the three-position indication and locking device of the drawer base of the circuit breaker includes a bottom plate 1, a driving device 2, a position indicating member 3 and a locking member 4, wherein

[0036] The driving device 2 is detachably arranged on the base plate 1, and the position indicator 3 is arranged on the base plate 1 and is connected to the driving device 2 in transmission, so as to switch between the three positions of separation, test and connection as required. The indicator 3 cooperates to lock the position indicator 3 when it is in the desired position, so that the three-position indicating locking device of the drawer base has a simple structure and can accurately and reliably displ...

Abstract

The invention discloses a three-position indication locking device for a circuit breaker drawer seat, which comprises a bottom plate (1) and a driving device (2) arranged on the bottom plate; a position indicator (3) is arranged on the bottom plate (1) and is connected with the drive unit (2) is geared to switch between the three positions; the locking member (4), cooperating with the position indicator (3) to lock the position indicator (3) when it is in the desired position, The three-position indicating and locking device of the drawer seat has a simple structure, can accurately and reliably display the three positions, and has stable and reliable performance.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a three-position indicating locking device for a drawer seat of a circuit breaker. Background technique [0002] Existing frame circuit breakers are usually installed in the switch cabinet when in use, and now a drawer structure is more common, that is, the circuit breaker body can be rolled into the drawer seat of the switch cabinet, and during the installation process In this process, the user needs to observe the positional relationship between the circuit breaker body and the drawer seat, that is, the state of the circuit breaker body and the drawer seat at the three positions of separation, test and connection, so as to avoid the circuit breaker from not being properly shaken or excessively shaken and causing a circuit breaker. Incorrect installation between the appliance body and the drawer base. [0003] However, the existing three-position indication and locking...
