Description
Technical field
The present invention relates to a kind of mechanical-electric interlocking device, particularly a kind of interlock that is applicable to isolating switch, automatic change-over.
Background technology
Interlock is widely used in the middle of device for switching, the complete set of equipments; its main purpose be play the protection personal safety, prevent faulty operation and guarantee electricity consumption order etc.; difference according to the electrical equipment type; the interlock of selecting is also different, and mechanical interlocking, electrical interlock, electromagnetic lock, microcomputer locking, Mechanically programm's lock etc. are generally arranged.Consider the feature of electric equipment and the factor of cost, isolating switch, automatic change-over generally adopt mechanical interlocking or electrical interlock, mechanical interlocks normal operation steel wire rope or leverage guarantee the operating mechanism akinesia with the change of mechanical location; The interlock electrical interlock generally has two kinds of interlock methods, a kind of is the action of going to control operation mechanism by the interlock auxiliary contact on the operating mechanism (Chang Kai or normally closed), another kind of electrical interlock is to utilize the interlock auxiliary contact (Chang Kai or normally closed) on the range switch operating mechanism to control, during the handle of Drawing switch, interlock auxiliary contact (Chang Kai or normally closed) cuts off circuit.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the purpose of this invention is to provide a kind of mechanical-electric interlocking device, to realize having the function of machinery and electric dual interlock, the characteristics such as whole mechanism operation is simple, safe and reliable, volume is little, economical and practical.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution used in the present invention is as follows:
A kind of mechanical-electric interlocking device is comprised of indication piece, panel, jump ring, spring, spring base, support, cam washers, axle sleeve, pedestal, rotating shaft, sensitive switch etc., and the device feature is: a band circular hole block card is arranged on the indication piece; Panel round hole one side has a draw-in groove; At support 1 sensitive switch is housed, in the pedestal bilateral symmetry that cam washers is housed a sensitive switch is housed respectively; Described spring base is arranged on the axle sleeve, pocketed springs and jump ring on spring base, and indication piece inserts panel, passes spring and links to each other with rotating shaft with jump ring.
Described a kind of mechanical-electric interlocking device is characterized in that adding padlock can not mode of operation the time when device is in, and the sensitive switch that is contained on the support disconnects, and makes dump, realizes the function of electrolock; Being stuck in the square draw-in groove of panel round hole one side with the circular hole block card on the while indication piece, the connecting rod that links to each other with indication piece is pulled up and is stuck, reaches the purpose of mechanical caging.
Described a kind of mechanical-electric interlocking device is characterized in that being in when not adding the padlock normal operating state when device, and the cam washers that is enclosed within the rotating shaft can make sensitive switch closed or disconnect in left-right rotation.
In sum, the present invention has the characteristics of control two-way circuit on-off when realizing the mechanical electric interlock.
Beneficial effect: mechanical-electric interlocking device of the present invention has machinery and the function of electric dual interlock, the characteristics such as whole mechanism operation is simple, safe and reliable, volume is little, economical and practical.
Description of drawings

Fig. 2 is that the present invention adds the padlock normal operating state.
Fig. 3 is that the present invention does not add the padlock normal operating state.
Embodiment
The present invention will be further explained below in conjunction with accompanying drawing.
As shown in Figure 1, be mechanical-electric interlocking device of the present invention.This mechanical-electric interlocking device is comprised of indication piece 1, panel 2, jump ring 3, spring 4, spring base 5, support 6, cam washers 9, axle sleeve 10, pedestal 11, rotating shaft 13, sensitive switch 7, the parts such as 8 and 12.One band circular hole block card is arranged on the indication piece 1; Panel 2 round holes one side has a draw-in groove; At support 61 sensitive switch is housed, in pedestal 11 bilateral symmetry that cam washers 9 is housed a sensitive switch is housed respectively.Described spring base 5 is arranged on the axle sleeve 10, pocketed springs 4 and jump ring 3 on spring base 5, and indication piece 1 inserts panel 2, passes spring 4 and links to each other with rotating shaft 13 with jump ring 3.
As shown in Figure 2, add padlock can not mode of operation the time when device is in, the sensitive switch 7 that is contained on the support 6 disconnects, and makes dump, realizes the function of electrolock; Being stuck in the square draw-in groove of panel 2 round holes one side with the circular hole block card on the while indication piece 1, the connecting rod that links to each other with indication piece is pulled up and is stuck, reaches the purpose of mechanical caging.
As shown in Figure 3, when device is in when not adding the padlock normal operating state, the cam washers 9 that is enclosed within the rotating shaft 13 can make sensitive switch 8 and 12 closed or disconnections in left-right rotation, when realizing the mechanical electric interlock, has the characteristics of control two-way circuit on-off.
