Abstract
The utility model relates to a protective hook of an isolating switch. The protective hook of the isolating switch comprises a base, a spindle is arranged on the base, two post insulators are further arranged on the base, one end of a conducting arm is movably connected on one post insulator, a lock hook is arranged at the other end of the conducting arm, and a lock hook holding groove is arranged in the other post insulator. The protective hook of the isolating switch is simple in structure, disconnection and connection of contact fingers with a contact are achieved by mechanical force, and accordingly personal injury of workers due to the fact that the contact fingers are suddenly disconnected with the contact to generate electric arcs caused by accidents is avoided.
Description
Technical field
The utility model relates to a kind of protection hook, especially relates to a kind of protection hook of isolating switch.
Background technology
At present, fingertip on the isolating switch directly contacts with contact, when have overcurrent by or when having unexpected situation to occur, fingertip can eject from normal combined floodgate suddenly, the electric arc that produces like this can threaten to staff's personal safety, and will guarantee normal power-up, then needs very large combined floodgate clamping force, often make contact site serious wear behind divide-shut brake repeatedly, the useful life of having reduced equipment.
Summary of the invention
In order to overcome defects, the utility model provides a kind of protection hook of isolating switch, and when avoiding fortuitous event to occur, fingertip separates suddenly the potential safety hazard that causes with contact.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of protection hook of isolating switch; comprise base; described base is provided with a main shaft; also be provided with two post insulators on the base; be flexibly connected conductive arm one end on one post insulator; the other end of conductive arm is provided with mousing-hook, and another post insulator is provided with the mousing-hook standing groove.
Further, main shaft is provided with link insulator by pull bar, and the link insulator other end is connected on the conductive arm.
Further, pull bar is connected with joint by main shaft.
Further, be provided with caging bolt in the mousing-hook standing groove.
The beneficial effects of the utility model are: simple in structure, realize separating and closure of fingertip and contact by mechanical force, when overcurrent is arranged by fingertip and contact, because conductive arm is that linear pattern is stressed, effectively suffered electric power is transmitted on the post insulator at two ends, guaranteed the normal power-up of fingertip and contact, and the mousing-hook on the conductive arm and caging bolt, reduce electric power to the impact of post insulator, better guaranteed the normal of energising, avoided the fingertip that causes because of accident and produce electric arc to staff's personal injury unexpected separation of contact; And the contact site behind divide-shut brake repeatedly also without noticeable wear, extension device useful life; When needs separate fingertip and contact, only need to use mechanical force just can realize separating of fingertip and contact.
Description of drawings
Fig. 1 is the utility model fingertip and contact isolating construction schematic diagram;
Fig. 2 is the utility model fingertip and contact closure structural representation;
Fig. 3 is the vertical view of Fig. 2.
Among the figure: 1, base; 2, main shaft; 3, post insulator; 4, conductive arm; 5, mousing-hook; 6, put the unhook standing groove; 7, pull bar; 8, link insulator; 9, joint; 10, caging bolt; 11, fingertip; 12, contact.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail: a kind of protection of isolating switch is linked up with as shown in Figure 1 to Figure 3, comprise base 1, base 1 is provided with a main shaft 2, also be provided with two post insulators 3 on the base 1, be flexibly connected conductive arm 4 one ends on one post insulator 3, the other end of conductive arm 4 is provided with mousing-hook 5, and another post insulator 3 is provided with mousing-hook standing groove 6; Main shaft 2 is provided with link insulator 8 by pull bar 7, and link insulator 8 other ends connect conductive arm 4; Pull bar 7 is connected with joint 9 by main shaft 2; Be provided with caging bolt 10 in the mousing-hook standing groove 6.
Realize separating and closure of fingertip and contact by mechanical force, when overcurrent is arranged by fingertip and contact, because conductive arm is that linear pattern is stressed, effectively suffered electric power is transmitted on the post insulator at two ends, guaranteed the normal power-up of fingertip and contact, and the mousing-hook on the conductive arm and caging bolt, reduce electric power to the impact of post insulator, better guaranteed the normal of energising, avoided the fingertip that causes because of accident and produce electric arc to staff's personal injury unexpected separation of contact; And the contact site behind divide-shut brake repeatedly also without noticeable wear, extension device useful life.
When the closed fingertip 11 of needs and contact 12, only need pulling connection mechanism 9 downwards, 7 drive link insulators 8 move downward thereby connection mechanism 9 drives pull bar, link insulator 8 is connected with conductive arm 4, conductive arm 4 moves downward, mousing-hook 5 is stuck in the mousing-hook standing groove 6 of post insulator 8, and 10 pairs of mousing-hooks 5 of caging bolt are spacing, prevents that the fingertip that causes because of reasons such as accidents from separating suddenly the electric arc of generation to staff's injury with contact; When needs separate fingertip and contact, need use upwards jack-up connection mechanism 9, connection mechanism 9 drives pull bars 7 and link insulator 8 actions, the jack-up conductive arm 4 that makes progress, thus so that mousing-hook 5 disengaging mousing-hook standing grooves 6 are realized separating of fingertip and contact.
This structure is to realize separating and closure of fingertip and contact by mechanical force, avoid the fingertip that causes because of accident and contact unexpected separate or the closed electric arc that produces to staff's personal injury.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
