Description
Technical field
The utility model belongs to high-tension distribution equipment technical field, especially relates to a kind of interlock.
Background technology
Interlock is very extensive in the application of industrial safety field, is exposing a large amount of dangerous matter sources: the gear of rotation, the rope of motion etc., if without any additional protection setting, workman directly contacts this class dangerous matter sources, may cause industrial accident in factory.For fear of the generation of this class accident, select to add extra protector, thus the generation of minimizing accident.
In high-voltage electrical apparatus structural establishment, usually can ensure with interlock workman's safety, each parts of common interlock
oneas adopt mild steel to adopt NaOH solution to heat workpiece is carried out to treatment surface protection, but resistance to corrosion is low, product material easily produces distortion before reaching heat-resistant limit.Interlock internal electrical magnet is general adopts simple sheath body to protect, and coil and clamshell exist the gap of a bit, easily make moist, and produce galvano-cautery, have affected security performance.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art part, and provides a kind of surperficial resistance to corrosion strong, the interlock that security performance is higher.
The purpose of this utility model solves by following technical proposal:
An interlock, comprises interlocking bearing, it is characterized in that: described interlocking bearing inside is provided with connecting rod, and interlocking bearing left side is fixed with sensitive switch No. one, and interlocking bearing right side is fixed with sensitive switch No. two, and interlocking bearing below has been bolted bent plate; On described bent plate, be fixed with rotary magnet, be fixed with baffle plate on rotary magnet, the described baffle plate other end is inner in interlocking bearing;
Described rotary magnet inside includes electromagnet coil, and this electromagnet coil is for adopting the injection molded electromagnet coil of epoxy resin integral type;
The material of described connecting rod is carbon steel, and its surface electrical is coated with zinc layer;
The material of described bent plate is carbon steel, and its surface electrical is coated with zinc layer;
The material of described interlocking bearing is aluminium, and this interlocking bearing is the interlocking bearing through hard anodize.
The cross section of bent plate described in the utility model is L shaped.
Compared to the prior art the utlity model has following characteristics and beneficial effect:
When 1, this interlock can guarantee that protective cover in equipment is opened, integrated model shuts down, guarantee workman check with maintenance process in safety.
2, parts surface adopts hard anodizing and zinc-plated processing, makes product before heat-resistant limit, not produce distortion, has improved its security performance, and its surperficial resistance to corrosion has also obtained reinforcement.
3, electromagnet coil adopts the injection moulding of epoxy resin integral type, is not easy to make moist and produces galvano-cautery, improves security performance and useful life.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model.
Fig. 2 is the right TV structure schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1 and Figure 2, a kind of interlock, comprise interlocking bearing 1, described interlocking bearing 1 inside is provided with connecting rod, interlocking bearing 1 left side is fixed with sensitive switch 2 No. one, interlocking bearing 1 right side is fixed with sensitive switch 3 No. two, and interlocking bearing 1 below has been bolted bent plate 4, and the cross section of described bent plate is L shaped.On described bent plate 4, be fixed with rotary magnet 5, be fixed with baffle plate 6 on rotary magnet 5, described baffle plate 6 other ends are in interlocking bearing 1 inside.
When the protective cover of interlock place equipment is closed, baffle plate 6 closures on rotary magnet 5, stop that connecting rod slides, sensitive switch 2 closures now, and equipment is in operating state; When the protective cover of equipment is opened, the baffle plate 6 being arranged on rotary magnet 5 is opened, and connecting rod walking touches to No. two sensitive switches 3, and now complete equipment decommissions.Workman can check or keep in repair device interior, and workman's safety has obtained guarantee.
Rotary magnet described in the utility model 5 inside include electromagnet coil, and this electromagnet coil is for adopting the injection molded electromagnet coil of epoxy resin integral type; This electromagnet coil is not easy to make moist and produces galvano-cautery, and its security performance and useful life are all significantly improved.
The material of connecting rod and bent plate 4 is carbon steel, and its surface is all electroplate with zinc layer; The material of interlocking bearing 1 described in the utility model is aluminium, and this interlocking bearing 1 is through the interlocking bearing 1 of hard anodize.This product does not produce distortion before heat-resistant limit, has improved its security performance, and its surperficial resistance to corrosion has also obtained reinforcement.
Claims (2)
1. an interlock, comprise interlocking bearing, it is characterized in that: described interlocking bearing inside is provided with connecting rod, interlocking bearing left side is fixed with sensitive switch No. one, interlocking bearing right side is fixed with sensitive switch No. two, and interlocking bearing below has been bolted bent plate; On described bent plate, be fixed with rotary magnet, be fixed with baffle plate on rotary magnet, the described baffle plate other end is inner in interlocking bearing;
Described rotary magnet inside includes electromagnet coil, and this electromagnet coil is for adopting the injection molded electromagnet coil of epoxy resin integral type;
The material of described connecting rod is carbon steel, and its surface electrical is coated with zinc layer;
