Abstract
The utility model relates to a change-over switch capable of realizing lead sealing, which comprises an insulation shell and an operating handle. A positioning device is arranged on the shell, a plurality of positioning holes are arranged on the positioning device, a through hole is arranged on the operating handle, and lead sealing is realized through a lead sealing wire penetrating through the through hole and the corresponding positioning holes. The change-over switch is simple in structure, low in cost, simple and convenient in operation, safe and reliable.
Description
Technical field
The utility model relates to a kind of device for switching, and particularly a kind of change over switch of lead-sealable actuation belongs to the appliance switch technical field.
Background technology
In the distribution box of existing rail vehicle; As the common employing of circuit controling switch is knife switch; But because the space of distribution box is limited; And the protective capacities of knife switch is lower, inapplicablely in high-speed track vehicles such as EMUs, uses, and therefore need replace the knife switch that in the past used with the less change over switch of volume.
Change over switch is a kind of device for switching that supplies two-way or the above power supply of two-way or load transfer to use, and is assembled by the multilayer insulation housing, mainly comprises contact system, detent mechanism, operating grip etc.Wherein contact system is to be made up of several stationary contact headstock and moving contacts in the movable support that are embedded in the insulation shell; With in the rotating shaft of handle, be threaded to diverse location with rotating shaft and use circuit to be switched on or switched off, through detent mechanism; Dispose different locating parts, to obtain the switch of different gears.
For guaranteeing circuit safety, only allow this change over switch of personnel operation of authority, for this reason; The safeguard measure of adopting limit usually be with switch when certain position of the switch; As carrying out lead sealing when the on-position, and this lead sealing only allows have the personnel of authority to remove to it, so that can be only through it there being the manual cut-off switch of operating personnel of authority; Equally, can only close through the manual on of the personnel that lead sealing had authority.
In the prior art, the position that generally is employed in the change over switch handle installs closure construction additional, and this capping comes lead sealing through lead sealing lock or lead sealing wire, but this lead seal structure is complicated, and cost is higher.
Summary of the invention
The utility model main purpose is to address the above problem, and provides a kind of simple in structure, and cost is low, the change over switch of safe and reliable lead-sealable actuation.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
A kind of change over switch of lead-sealable actuation; Comprise insulation shell, operating grip, a location device is set on said housing, on said positioner, have a plurality of location holes; On said operating grip, have a through hole, the lead sealing line passes said through hole and realizes lead sealing with corresponding said location hole.
Further, said positioner is an annular packing ring, and said packing ring passes said operating grip and is fixed on the said housing, and the shirt rim of a protrusion is set on said packing ring, and said location hole is arranged on the said shirt rim.
Content to sum up, the change over switch of the described a kind of lead-sealable actuation of the utility model, simple in structure, cost is low, and is simple to operation, and safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
As shown in Figure 1, operating grip 1, packing ring 2, shirt rim 3, location hole 4, through hole 5.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of change over switch of lead-sealable actuation comprises insulation shell (not shown) and operating grip 1, and operating grip 1 is fixed on the housing, is marked with different gears at housing, and the different gear of rotating operating handle 1 correspondence is realized different functions.
One location device is set on housing, in the present embodiment, as shown in Figure 1; Positioner is an annular packing ring 2, and packing ring 2 passes operating grip 1 and is fixed on the housing, and the shirt rim 3 of a protrusion is set on packing ring 2; Shirt rim 3 is positioned at the position of operating grip 1, on shirt rim 3, has a plurality of location holes 4, and the position that is provided with of location hole 4 can be corresponding with the different gears of operating grip 1; Also can not need correspondence, only need drive a series of location hole 4 and get final product, have a through hole 5 on the operating grip 1; When operating grip 1 rotates to a certain gear, as rotate to when connecting gear, pass through hole 5 and can realize lead sealing with through hole 5 nearest location holes 4 with the lead sealing line; Make operating grip 1 be fixed in this gear, simple to operation.
In use, operating grip 1 usefulness lead sealing line is locked on the normal gear, when abnormal conditions take place when, can operating grip 1 after the operator need obtain authorizing, lead sealing simultaneously is destroyed, and notes this switch and is operated; After the operation, must guarantee after abnormal conditions are got rid of handle 1 to be returned to normal gear, pin with the lead sealing line once more and protect by the special messenger.Authorize and record with this activation manipulation, realize protection important circuit and electric control system critical function to important circuit and critical function.
As stated, in conjunction with the given scheme content of accompanying drawing, can derive the similar techniques scheme.In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
Claims (2)
1. the change over switch of a lead-sealable actuation; Comprise insulation shell, operating grip; It is characterized in that: a location device is set on said housing; On said positioner, have a plurality of location holes, on said operating grip, have a through hole, the lead sealing line passes said through hole and realizes lead sealing with corresponding said location hole.
2. the change over switch of lead-sealable actuation according to claim 1; It is characterized in that: said positioner is an annular packing ring; Said packing ring passes said operating grip and is fixed on the said housing, and the shirt rim of a protrusion is set on said packing ring, and said location hole is arranged on the said shirt rim.
