Description

A kind of low voltage fuse type isolating switch

Technical field

The utility model is related to disconnecting switch technical field of structures, and in particular to a kind of low voltage fuse type isolating switch.

Background technology

Low voltage fuse type isolating switch is that one kind is applied in outdoor electric line, as the short of inducer for line outlet end of transformer Road, overload protection device, there is an a large amount of application in national Transformation of Rural Electrified Wire Netting, and mainly there are upside-down mounting and 45 ° of inclination angles peaces in when installation Dress；Mainly come by the clamping force of contact itself after outdoor low-tension fuse type isolation switch product on the market closes a floodgate at present Keep moving contact closed state, once contact clamping force failure or electric loop in electrodynamic repulsion force influence, then in upside-down mounting The rotatable portion of product will be fallen along holder automatically under the effect of gravity；Reliability service and behaviour of the such case for power grid The personal safety for making personnel is extremely hazardous hidden danger.

Utility model content

The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, a kind of reliable working performance, no is provided Easily unexpected disconnection, a kind of low voltage fuse type isolating switch safe to use, simple in structure.

To achieve the above object, the technical solution adopted in the utility model is：It includes pedestal, static contact, moving contact, closes Locking device, No.1 support insulator, No. two support insulators, wherein No.1 support insulator, No. two support insulators are fixed It is set on the base, static contact is fixed on No.1 support insulator, and moving contact, which is screwed on, to be arranged in No. two support insulators On, static contact contacts setting with moving contact, and blocking device is provided between static contact and moving contact, and the blocking device includes Draw ring, locking hook, No.1 shaft, No. two shafts, torsional spring, locking button, wherein draw ring is screwed in moving contact end by No.1 shaft Head upside, locking hook are screwed in by No. two shafts on the downside of moving contact end, the locking hook by the strip of the upper end with The card slot of draw ring lower end matches active card and sets, and locking button is fixed on the No.1 support insulator on the downside of static contact, is closed Latch hook fastens setting with locking button, and torsional spring is arranged in No. two shafts, and described one suspension column of torsional spring is fastened on locking hook, turns round Spring another suspension column is fastened in No.1 shaft.

With the above structure, the utility model has the beneficial effect that：A kind of low voltage fuse type described in the utility model Disconnecting switch, blocking device design, ensure that disconnecting switch will not disconnect in use because of fortuitous event, while again The normal use for not interfering with disconnecting switch ensure that user of service's is safe to use, the utility model have it is simple in structure, if The advantages that it is reasonable to set, low manufacture cost.

Description of the drawings

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, other can be obtained according to these attached drawings Attached drawing.

Pedestal 1, moving contact 3, blocking device 4, draw ring 5, locking hook 6,7, No. two shafts 8 of No.1 shaft, is turned round static contact 2 11, No. two spring 9, locking button 10, No.1 support insulator support insulators 12.

Specific implementation mode

The utility model will be further described below with reference to the accompanying drawings.

Referring to as shown in figs 1 to 6, present embodiment include pedestal 1, static contact 2, moving contact 3, blocking device 4, 11, No. two support insulators 12 of No.1 support insulator, wherein 11, No. two support insulators 12 of No.1 support insulator are fixed Be arranged on pedestal 1, static contact 1 is fixed on No.1 support insulator 11, moving contact 3 be screwed on setting it is exhausted in No. two pillars On edge 12, static contact 2 contacts setting with moving contact 3, and blocking device 4 is provided between static contact 2 and moving contact 3, described Blocking device 4 includes draw ring 5, locking hook 6,7, No. two shafts 8 of No.1 shaft, torsional spring 9, locking button 10, and wherein draw ring 5 passes through one Number shaft 7 is screwed on the upside of 3 end of moving contact, and locking hook 6 is screwed in by No. two shafts 8 on the downside of 3 end of moving contact, described Locking hook 6 matches active card with the card slot of 5 lower end of draw ring by the strip of the upper end and sets, and realizes the connection of locking hook 6 and draw ring 5 Dynamic setting, locking button 10 are fixed on the No.1 support insulator 11 of 2 downside of static contact, locking hook 6 and 10 button of locking button Setting is closed, torsional spring 9 is arranged in No. two shafts 8, described 9 one suspension columns of torsional spring are fastened on locking hook 6, torsional spring another column Foot is fastened in No.1 shaft 7.

At work, it is that moving contact 3 is closed to close lock to present embodiment, is in close contact with static contact 2, and be latched at this time Hook 6 and locking button 10 fasten, and moving contact will not be opened accidentally, and when needing to open a sluice gate, pull draw ring 5 using tool, at this time draw ring 5 Linkage drives locking hook 6 to move backward, and offsets the tension of torsional spring 9, so that locking hook 6 and locking button 10 is separated, moving contact can be free It opens.
