Abstract
The utility model relates to an open type load switch which is a common low-voltage electrical apparatus for manually switching on and breaking off a load circuit. Because of lacking a locking device, accidents which can harm personal safety and equipment occur due to the unwanted operation. Aiming at the problem, the utility model provides the knife switch with a locking device, which is secure, reliable, convenient and practical. The utility model has the main technical characteristic that a specifically designed locking device is assembled on the general open type load switch. The position of a touch cutter is locked, and the touch cutter can not be removed to other positions without unlocking.
Description
The utility model belongs to switching device.
Open-type load switch hereinafter to be referred as switch, is a kind of manual connection of confession commonly used and the low-voltage electrical apparatus of disjunction load circuit.Switch may be directed at the accident of harm personal safety and equipment owing to malfunction because of lacking locker.The existing way that prevents the malfunction switch is the sign board that hangs up on switch with " please don't move " printed words, or locks the switch-box that switch is housed.These ways or safe and reliable inadequately, perhaps convenient and practical inadequately.
The purpose of this utility model provides a kind of safe and reliable, convenient and practical switch exactly for overcoming above-mentioned shortcoming.
Technical essential of the present utility model is custom-designed locker of assembling on general open-type load switch, to the azimuth caging of contact knife, contact knife can not be shifted to other position without unblanking.
Task of the present utility model can realize in two ways.Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a kind of mode that realizes the present technique main points.With reference to Fig. 1, this locker hangs (3) by button and lock (4) is formed.Button hangs on the contact knife insulation handle (2) and base (1) that (3) be contained in switch respectively.Like this, only open lock (4) and could change the position of contact knife.
Fig. 2 is the another way that realizes the present technique main points.With reference to Fig. 2, this locker is made up of a connecting piece (5), lock (4) and brake bars (6).Connecting piece (5) is installed on the base (1), one braking keyhole (7) is arranged on the connecting piece (5), be used to support brake bars (6), lock (4) can be contained in connecting piece (5) and upward or with connecting piece (5) make one, lock (4) lockable brake bars (6).Like this, brake bars (6) is placed position shown in Figure 2, i.e. the orientation of lockable contact knife.Only open lock (4), mobile brake bars (6) could change the position of contact knife.
The utility model compared with prior art, has safe and reliable, convenient and practical advantage, investment seldom only needs on original open-type load switch, slightly to make improvements, as long as can be avoided the accident that causes because of the malfunction switch.
Claims (3)
1. can lock the open-type load switch device, contain an open-type load switch, it is characterized in that: a custom-designed locker is housed, on general open-type load switch the azimuth caging of contact knife.
