Abstract
The utility model provides a kind of back-up protection device, including Switch main body, Switch main body is at least four groups, Switch main body includes shell, coil is provided with shell, tripping mechanism, handle, moving contact, gas discharger and explosion-protection equipment, shell two ends are provided with connector lug, described coil two ends are connected in series with gas discharger, coil one end is electrically connected with the connector lug of shell one end, tripping mechanism is linked with handle, moving contact is linked with tripping mechanism, tripping mechanism is electrically connected with the connector lug of the shell other end, explosion-protection equipment is arranged on the lower end for being located at gas discharger in shell, tripping mechanism has connecting hole, also include link gear, linked between Switch main body by the connecting hole of link gear through tripping mechanism.This product realizes linkage by increasing connecting hole on the tripping mechanism of switch by gangbar, and it is that can control multiple switch while being turned on and off to promote a handle, very useful and very laborsaving, easy to operate.
Description
Technical field
The utility model is related to a kind of switch, more particularly to a kind of back-up protection device.
Background technology
Handle is all linked together realization while being turned on and off, behaviour by electrical apparatus release auxiliary switch in the market
Make inconvenient, be turned on and off needing firmly can just move switch, and handle sets to be integrated and is inconvenient to dismantle, repairs, and
And the electric arc produced between the end of a thread easily triggers blast, so needing a kind of back-up protection device to solve these problems.
Utility model content
For existing technical deficiency, the utility model provides a kind of back-up protection device.
To achieve these goals, technical solution adopted in the utility model is：A kind of back-up protection device, including switch
Body, described Switch main body is at least four groups, described Switch main body include in shell, shell provided with coil, tripping mechanism,
Handle, moving contact, gas discharger and explosion-protection equipment, described shell two ends are provided with connector lug, described coil two ends and gas
Body discharger is connected in series, and described coil one end is electrically connected with the connector lug of shell one end, described tripping mechanism and handle
It is linked, moving contact is linked with tripping mechanism, described tripping mechanism is electrically connected with the connector lug of the shell other end, institute
The explosion-protection equipment stated is arranged on the lower end for being located at gas discharger in shell, and described tripping mechanism has connecting hole, in addition to
Linked between link gear, Switch main body by the connecting hole of link gear through tripping mechanism.
Described link gear is gangbar, and described gangbar is linked through the connecting hole of tripping mechanism.
Described explosion-protection equipment is arc extinguishing stone.
The beneficial effects of the utility model：The utility model provides a kind of back-up protection device, and this product passes through in switch
Increase connecting hole on tripping mechanism, realized and linked by gangbar, it is that controllable multiple switch is opened simultaneously to promote a handle
Or close, explosion-protection equipment is avoided that switch blast, very useful and very laborsaving, easy to operate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, a kind of back-up protection device, including Switch main body, described Switch main body is at least four groups, described
Switch main body includes shell 1, provided with coil 2, tripping mechanism 3, handle 4, moving contact 5, gas discharger 6 and explosion-proof in shell 1
Device 9, the described two ends of shell 1 are provided with connector lug 7, and the described two ends of coil 2 are connected in series with gas discharger 6, described
The one end of coil 2 is electrically connected with the connector lug 7 of the one end of shell 1, and described tripping mechanism 3 is linked with handle 4, moving contact 5 with
Tripping mechanism 3 is linked, and described tripping mechanism 3 is electrically connected with the connector lug 7 of the other end of shell 1, described explosion-protection equipment 9
The lower end for being located at gas discharger 6 in shell 1 is arranged on, described tripping mechanism 3 has connecting hole 8, in addition to link gear,
Linked between Switch main body by the connecting hole 8 of link gear through tripping mechanism 3, tripping mechanism and other assemblies are routine
Technology, does not make excessively to repeat to this.
Described link gear is gangbar, and described gangbar is linked through the connecting hole 8 of tripping mechanism 3.
Described explosion-protection equipment 9 is arc extinguishing stone, and arc extinguishing stone is circuit explosion-protection equipment conventional in the market.
The beneficial effects of the utility model：The utility model provides a kind of back-up protection device, and this product passes through in switch
Increase connecting hole on tripping mechanism, realized and linked by gangbar, it is that controllable multiple switch is opened simultaneously to promote a handle
Or close, it is very useful and very laborsaving, it is easy to operate.
