Technical field
The present invention relates to spring mechanism high-pressure vacuum breaker manual energy storing device, especially a kind of vacuum circuit-breaker is used manual energy storing device.
Background technology
The spring mechanism high-pressure vacuum breaker is a kind of with the high-pressure vacuum breaker of spring mechanism as the operating mechanism configuration.Use reliably for greater safety, this circuit breaker generally disposes manual stored energy mechanism.The manual stored energy mechanism that existing vacuum circuit-breaker generally uses is energy storage handle and stored energy mechanism split-type structural; When manual energy storage; Need the energy storage handle be inserted into and carry out energy storage on the stored energy mechanism operating axis; And the energy storage handle is as annex at random, and not enough below existing: (1) volume is little, not manageability; (2) the energy storage handle needs 360 degree rotary manipulations, and operational torque is big; (3) the positive reservation stored energy operation hole that needs of vacuum circuit-breaker, barrier propterty reduces and is not attractive in appearance.
Summary of the invention
The purpose of this invention is to provide a kind of operational torque little, use and manage all very easily vacuum circuit-breaker and use manual energy storing device.
A kind of vacuum circuit-breaker is used manual energy storing device; Its special feature is; Comprise the folding handle and the handle set that are hinged; End at this handle set is provided with a stepped hole, matches with the stored energy mechanism axle thereby the check needle bearing is installed in this stepped hole, and a spacer pin also is installed on aforementioned handle set.
Wherein on handle set, also be provided with a boss, cooperate with aforementioned boss and carry out spacing folding handle thereby on folding handle, be provided with a ratchet.
Wherein boss is a terraced steps.
Wherein on folding handle, also be provided with anti-skidding nock, and on folding handle, also have rectangular opening.
The invention has the beneficial effects as follows that the present invention utilizes the fiting effect of ratchet and terraced steps to form the triangle rock-steady structure, makes manual stored energy operation form change into the operation that swings up and down among a small circle, operational torque is light.The manual energy storing device that this device is integrated, as a whole with vacuum circuit-breaker, need not annex in addition, better management.

Embodiment
Like Fig. 1,2, shown in 3, comprise mechanism's dividing plate 1, folding handle 2, handle set 3, stepped hole 4; Needle bearing 5, stored energy mechanism axle 6, spacer pin 7, terraced steps 8, arc shaped groove 9; Ratchet 10, anti-skidding nock 11, back-moving spring 12, reference column 13, the rectangular opening 14 of ratchet 10 location.
A kind of vacuum circuit-breaker is used manual energy storing device; Comprise the folding handle 2 and handle set 3 that are hinged; End at this handle set 3 is provided with a stepped hole 4; Match with stored energy mechanism axle 6 thereby check needle bearing 5 is installed in this stepped hole 4, a spacer pin 7 also is installed on aforementioned handle set 3.
Wherein on handle set 3, also be provided with a boss; Thereby on folding handle 2, being provided with a ratchet 10 cooperates with aforementioned boss and carries out spacing to folding handle 2; Boss is specially terraced steps 8; On folding handle 2, also be provided with anti-skidding nock 11, and on folding handle 2, also have the rectangular opening 14 of ratchet 10 location.
Like Fig. 1,2, shown in 3, the present invention is a kind of vacuum circuit-breaker manual energy storing device, comprises the handle set 3 of activity in can be in 170 degree scopes movable folding handle 2 and the 40 degree scopes; Be positioned at handle set 3 one ends and be provided with stepped hole 4, stepped hole 4 built-in check needle bearings 5.Needle bearing 5 is connected with stored energy mechanism axle 6 during use, is positioned at handle set 3 middle parts and is provided with spacer pin 7 and terraced steps 8, and the arc shaped groove 9 on spacer pin 7 other ends and the mechanism's dividing plate 1 is a matched in clearance; Stored energy mechanism axle 6 is provided with back-moving spring 12, and folding handle 2 is " recessed " type groove structure, and the groove middle inside is provided with ratchet 10; The groove inner side step partly is provided with anti-skidding nock 11; Ratchet 10 is a variable-diameter structure, can cooperate with terraced steps 8, and ratchet 10 can be sagging naturally with gravity.
Like Fig. 1, shown in 2; Ratchet 10, folding handle 2 and 3 of handle sets adopt movable riveted joint mode; When manual energy storing device uses; Utilize the finger recess of vacuum circuit-breaker panel to scratch folding handle 2, utilize terraced steps 8 interlocks on the sagging naturally and handle set 3 of ratchet 10, form leg-of-mutton rock-steady structure; The people holds folding handle and is pressed in for 2 times under the counter-force effect of back-moving spring 12 and swings up and down in the 60 degree scopes, drives handle set 3 and drives 6 energy storage of stored energy mechanism axles with check needle bearing 5 on the handle set 3; After energy storage was accomplished, folding handle 2 slightly up lifted, and removes the constraint of 8 pairs of ratchets 10 of said terraced steps; Folding handle 2 and ratchet 10 are sagging naturally; Be fixed in the ratchet 10 locating rectangle holes 14, cover on the handle set 3, be in same horizontal plane with the vacuum circuit-breaker panel.
