Abstract
The utility model discloses an electric knife switch which comprises a base, a fuse shield, a power supply shield and a knife contacting handle, and is characterized in that a safety bar is fixed on the side surface of the fuse shield, stretches to the top end of the power supply shield and can be stopped by the knife contacting handle, so that the fuse shield can be prevented from being opened when the knife contacting handle is switched on. The electric knife switch can effectively prevent a fuse box from being opened under the condition that switching off is not conducted, thus ensuring the maintenance staff to be safe.
Description
Technical field
The utility model relates to a kind of electric knife switch switch.
Background technology
The electric knife switch switch is the simplest in the manual electrical equipment, uses more a kind of again low-voltage electrical apparatus switch.The effect of knife switch in circuit is: insulating power supply, to guarantee the safety of circuit and maintenance of equipment; The disjunction load is not as connect and low-voltage circuit that breaking capacity is little or directly start small-capacity motor continually.When the electric current through the electric knife switch switch surpassed the lowest high-current value of the fuse that connects, fuse will blow.Connecing fuse is a fairly simple thing, so the user can select do-it-yourself usually.But connect fuse is the work of part hazardous, does not connect fuse if there is outage earlier just to open guard shield, very likely leads and holds back electric shock.
The utility model content
The purpose of the utility model is to provide a kind of electric knife switch switch of safety utilization of electric power maintenance.
A kind of electric knife switch switch that the utility model provides; Comprise base, fuse guard shield, power supply guard shield, contact knife handle; The side that it is characterized in that said fuse guard shield is fixed with safe bar; This safe bar is stretched the top of sword power supply guard shield, can be stopped by the contact knife handle, and the fuse guard shield is opened when preventing contact knife handle combined floodgate.
In order to prevent that under the situation that the fuse guard shield is opened the contact knife handle closes a floodgate, through a support limited bolt that the contact knife handle closes a floodgate can prevent that the fuse guard shield from opening the time is housed on the said base.
Because the utility model is fixed with safe bar in the side of fuse guard shield; When the contact knife handle is in "on" position; One end of safe bar is positioned at the below of contact knife handle, and the maintenance personal can't open the fuse guard shield under the situation of not operating a switch, must earlier the contact knife handle be left behind if keep in repair; Just can open the fuse guard shield after the outage and keep in repair, so reach the purpose of safety utilization of electric power maintenance.
Description of drawings
Fig. 1 is the three-dimensional structure sketch map of the utility model;
Fig. 2 is the structural representation of the utility model fuse guard shield;
Fig. 3 is the scheme of installation of the utility model limited bolt.
Among the figure: 1, base; 2, fuse guard shield; 3, power supply guard shield; 4, contact knife handle; 5, safe bar; 6, limited bolt; 7, support.
Embodiment
Can find out that from Fig. 1 to Fig. 3 the utility model comprises contact knife handle 4, limited bolt 6, base 1 and is installed in fuse guard shield 2, the power supply guard shield 3 on the base 1.Wherein the side of fuse guard shield 2 is fixed with safe bar 5; One end of safe bar 5 stretches to the top of power supply guard shield; When contact knife handle 4 power switch are connected; Safe bar 5 is stopped by tentacle handle of a knife 4 can not move (like Fig. 2), thereby is preventing that fuse guard shield 2 is opened under the situation that contact knife handle 4 closes a floodgate.Be fixed with a support 7 on the said base 1, the limited bolt that can advance and retreat 6 (as shown in Figure 3) is housed on this support.After contact knife handle 4 is operated a switch outage, advance limited bolt 6, make the contact knife handle 4 in the course of the work can be because of the combined floodgate energized.After service work was accomplished, the fuse guard shield 2 that closes earlier withdrawed from limited bolt 6 then, closed a floodgate power connection to contact knife handle 4 again.
Claims (2)
1. electric knife switch switch; Comprise base (1), fuse guard shield (2), power supply guard shield (3), contact knife handle (4); The side that it is characterized in that said fuse guard shield (2) is fixed with safe bar (5); The top that this safe bar (5) reaches power supply guard shield (3) can be stopped that fuse guard shield (2) is opened when preventing contact knife handle (4) combined floodgate by contact knife handle (4).
2. electric knife switch switch according to claim 1 is characterized in that said base (1) upward is equipped with the limited bolt (6) that can prevent fuse guard shield (2) contact knife handle (4) combined floodgate when opening through a support (7).
