Abstract
An operation hand grip of a handcart type circuit breaker belongs to the technical field of electric switch accessories. The operation handle comprises a rocking handle, a rod body and an operation end, wherein the rocking hand is located on one end of the rod body, the operation end is located on the other end of the rod body; and the operation handle is characterized in also comprising a push handle, which is in the same line with the operation end, and is located at one side of the rocking handle. When an operator operates, one hand holds the rocking handle, and the other hand applies a push force on the push handle, thus avoiding upsetting force during the operation process, such that the operation end and a rotating screw are reliably engaged, and the operation stability is improved.
Description
Technical field
The utility model belongs to electric switch attachment technique field, is specifically related to a kind of operating grip of handcart type breaker.
Background technology
Handcart type breaker; Be to be installed in a kind of circuit breaker on the special handcart of extracting out to high-voltage switch gear; The switch cubicle that industry will be furnished with handcart type breaker is called the handcart cabinet; Because the handcart cabinet has good interchangeability, therefore can improve the reliability of power supply, can change subsequent use handcart if damage.For handcart type breaker; When circuit is debugged and is safeguarded; Need in switch cubicle, carry out the switching of service position and isolated location; Owing to when switching, need realize, so operating grip is the indispensable aid of handcart type breaker through operating grip (industry is referred to as chassis operating grip, propulsion plant operating grip) rotating screw bolt.
Fig. 3 is the operating grip of a kind of handcart type breaker common in the prior art, and it comprises shakes handle 1, the body of rod 2 and operating side 3, wherein shakes handle 1 and lays respectively at the body of rod 2 two ends with operating side 3, and the body of rod 2 has two bendings, forms to be similar to zigzag.Operating side 3 is used for and the rotating screw bolt engagement, shakes handle 1 and supplies the operator to control (hold and pinch).In actual use, the operator shakes handle 1 through rotation, just can drive rotating screw bolt through operating side 3 and rotate, to realize handcart type breaker moving in switch cubicle.Shake in the process of handle 1 in operator's manipulation; In order to make operating side 3 and rotating screw bolt positive engagement; So need following usually, the operator applies a thrust to shaking handle 1 in the process of shaking handle 1; But this thrust can produce one and makes operating side 3 and rotating screw bolt mesh unsettled inclination to cover moment simultaneously, and there is the anxiety of the engagement disengagement between renders operation end 3 and the rotating screw bolt in this tilting moment, and this kind situation is unfavorable for the operate as normal of operating grip.
In view of above-mentioned prior art, be necessary to improve, the technical scheme that will introduce below produces based on above-mentioned prerequisite.
Summary of the invention
The task of the utility model is to provide a kind of operator of helping avoid to occur when operation that the operating side is engaged with the fixed tilting moment of unstability with rotating screw bolt and the operating grip of using the handcart type breaker that improves the stability of operating.
The task of the utility model is accomplished like this; A kind of operating grip of handcart type breaker comprises and shakes handle, the body of rod and operating side, shakes the end that handle is positioned at the body of rod; The operating side is positioned at the other end of the body of rod; It is characterized in that also including a pushing handle, this pushing handle and described operating side remain on the same straight line, and are positioned at a said side of shaking handle.
The described body of rod of the utility model comprises jack back and connecting rod, and connecting rod is connected with jack back, and said operating side is positioned at an end of connecting rod, and said pushing handle is positioned at the other end of connecting rod.
The connected mode that the described connecting rod of the utility model is connected with jack back is for directly being connected or connecting indirectly.
Described directly being connected to of the utility model constitutes one with said connecting rod and said jack back.
The described indirect connection of the utility model is that said connecting rod is connected with the click-fit device through ratchet with said jack back.
The technical scheme that the utility model provides is when the operator operates; One holds to pinch and shakes handle, and another hand can be to pushing handle applied thrust, thereby can avoid in operating process, occurring the power of toppling; Make operating side and rotating screw bolt positive engagement, improve the stability of operation.

Fig. 2 is the second embodiment sketch map of the utility model.
Fig. 3 is the sketch map of the operating grip of the handcart type breaker in the prior art.
Embodiment
Embodiment 1:
Ask for an interview Fig. 1, the operating grip of the handcart type breaker that the utility model provides comprises be used for that the operator controls shake handle 1, the body of rod 2 and be used for the operating side 3 of rotating screw bolt engagement; Shake the end that handle 1 is formed in the body of rod 2; And operating side 3 is formed in the other end of the body of rod 2, shown in figure, also has a pushing handle 4 at this other end of the body of rod 2; This pushing handle 4 remains on the same straight line with operating side 3, and is positioned at a said side of shaking handle 1.That is to say the concentric and side when being positioned at the operator and operating in pushing handle 4 and operating side 3.
The aforesaid body of rod 2 comprises jack back 21 and connecting rod 22, and aforesaid operating side 3 is formed in an end (diagram left end) of connecting rod 22, and aforesaid pushing handle 4 is positioned at the other end (diagram right-hand member) that promptly is formed in connector 22.In the present embodiment, connecting rod 22 directly is connected with jack back 21, alleged here direct connection is as fixing with jack back 21 welding with connecting rod 22.
In use; Hand of operator is through pushing handle 4 assurance operating sides 3 and rotating screw bolt tight engagement; I.e. pushing pushing handle 4, pushing handle 4 is passed to operating side 3 through the connecting rod 22 of the body of rod 2 with thrust, operating side 3 receive thrust and with the rotating screw bolt tight engagement; Thereby in the process of operator's operating grip, operating side 3 all the time with the rotating screw bolt tight engagement.Operator's another holds and shakes handle 1, does not need this moment only need apply rotatory force and get final product shaking handle 1 applied thrust.After operating handle 1 turns over certain angle, can guarantee to continue smooth operating operation handle through the grip that replaces both hands, for example; When left hand is held pushing handle 4, and the right hand is held and is shaken handle 1 rotating operation handle, after shaking handle 1 and turning to left; Adopt the right hand to hold pushing handle 4; And handle 1 complete operation is shaken in left hand assurance, with this repeatedly, and up to complete operation.
Because after adopting the scheme of the utility model, the operator does not need to apply pushing force again from shaking handle 1, and can effectively avoid the generation of tilting moment.
Embodiment 2:
Only change connecting rod 22 and being connected of jack back 21 into indirect connection; Specifically be to be connected with click-fit device 5 through ratchet; Ratchet and click-fit make connecting rod 22 and jack back 21 both when one-directional rotation, combine; And when backward rotation, be separated, make the operator like this when the operating operation handle, the process of avoiding both hands to replace.All the other are all with the description to embodiment 1.
