Abstract
The present invention relates to breaker of switch cabinet technical fields, more particularly, to a kind of low-voltage circuit breaker operating handle auxiliary accessories.Including sleeve and handle, the sleeve is connected with handle, and the sleeve is equipped with the cross recess coordinated with breaker operator handle.The arm of force that breaker of switch cabinet operating handle can be extended, it is more laborsaving when making operator's operating breaker.
Description
Technical field
The present invention relates to breaker of switch cabinet technical fields, auxiliary more particularly, to a kind of low-voltage circuit breaker operating handle
Help accessory.
Background technology
Low-tension switch cabinet is suitable for the industries such as power plant, oil, chemical industry, metallurgy, weaving, skyscraper, as transmission of electricity,
Distribution and electric energy conversion are used.Switchgear is a kind of electric equipment, and outside line is introduced into master switch in cabinet, is opened subsequently into sub-control
It closes, each branch is set according to its needs.Switchgear has the advantages that breaking capacity is high, dynamic thermal stability is good and safe and reliable.
Existing to be limited because of cabinet size, low-voltage circuit breaker operating handle is smaller and short, and operating personnel need to expend larger
Strength could Operation switch divide-shut brake.Because cabinet size limits, low-voltage circuit breaker operating handle is smaller and short, operating personnel
It needs to expend larger strength ability Operation switch divide-shut brake.
Invention content
The present invention is at least one defect overcome described in the above-mentioned prior art, provides a kind of low-voltage circuit breaker operating handle
Auxiliary accessories can extend the arm of force of breaker of switch cabinet operating handle, more laborsaving when making operator's operating breaker.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of low-voltage circuit breaker operating handle auxiliary
Accessory, including sleeve and handle, the sleeve are connected with handle, and the sleeve is equipped with to be coordinated with breaker operator handle
Cross recess.
Pushing, the operator by the operation handlebar that the cross recess on present apparatus sleeve is nested into low tension switch cabinet breaker
Hand-held handle, you can realize the effect for extending the operating handle arm of force, existing low-tension switch cabinet breaker operator handle length is shorter,
The present apparatus can extend handle length, and more laborsaving when making operator's operating breaker, the present apparatus is simple in structure, just in application
On installation to operating handle, is detachably carried when that need not apply, the space in switchgear will not be occupied, avoided interference and open
Close the operation of cabinet.
Further, the sleeve lateral wall is equipped with the screw hole communicated with cross recess.When cross recess nesting to operation
When on handle, there can be certain gap between operating handle and cross recess, by the screw hole of sleeve lateral wall, be revolved using screw
Entering screw hole, screw head compresses operating handle, sleeve and operating handle is made closely to connect, in this way when operating breaker,
It would not loosen, can fall off from operating handle to avoid the present apparatus in operation between the present apparatus and operating handle
The problem of occur.
Further, the handle end is equipped with spherical portion.When operator operates the present apparatus, the end of operating handle
Handle end is designed as spherical portion by the palm of the hand that can withstand on operator, more comfortable when end can be made to oppress the palm of the hand, and is being grasped
Spherical portion prolongs the palm of the hand sliding when making, and reduces friction, keeps operation more convenient comfortable.
Further, it is equipped with anti-skid chequer on the inside of the cross recess.By adding anti-skid chequer, cross recess can be increased
Friction between operating handle makes the cooperation of sleeve and operating handle more fasten.Anti-skid chequer is handed over using cross in the present apparatus
Lines is pitched, twill or straight grain can also be used.
Further, the handle and sleeve are detachably connected by screw thread.If the more difficult operation of breaker operator handle,
The handle of replaceable different length, provides a variety of solutions.
Further, the handle and sleeve are insulation system, and the present apparatus is made of ABS, portable construction, insulation
Performance is good, and operator's electrocution conditions can be avoided to occur.
Compared with prior art, advantageous effect is：
1, the present apparatus can extend the arm of force of breaker operator handle so that more laborsaving when operator's operating breaker；
2, the present apparatus is simple and light, easy to use；
3, the present apparatus, which adds screw hole, can make sleeve and operating handle fixation, avoid falling off when using.
Description of the drawings
Fig. 1 is overall structure of the present invention.
Specific implementation mode
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；It is attached in order to more preferably illustrate the present embodiment
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of position relationship described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
As shown in Figure 1, a kind of low-voltage circuit breaker operating handle auxiliary accessories, including sleeve 1 and handle 2, sleeve 1 and handle
2 connections, sleeve 1 are equipped with the cross recess 11 coordinated with breaker operator handle.
It is pushing by the operation handlebar that the cross recess 11 on present apparatus sleeve 1 is nested into low tension switch cabinet breaker, behaviour
Work person's hand-held handle 2, you can realize the effect for extending the operating handle arm of force, existing low-tension switch cabinet breaker operator handle length
Shorter, the present apparatus can extend handle length, and more laborsaving when making operator's operating breaker, the present apparatus is simple in structure, is answering
Used time just installs to operating handle, is detachably carried when that need not apply, and will not occupy the space in switchgear, avoid
The operation of interferometric switch cabinet.
In the present embodiment, 1 side wall of sleeve is equipped with the screw hole 12 communicated with cross recess 11.When cross recess 11 is nested extremely
When on operating handle, there can be certain gap between operating handle and cross recess 11, by the screw hole 12 of 1 side wall of sleeve,
Screw hole 12 is screwed in using screw, screw head compresses operating handle, so that sleeve 1 and operating handle is closely connected, operating in this way
When breaker, would not be loosened between the present apparatus and operating handle, can to avoid the present apparatus in operation from
The problem of falling off on operating handle.
In the present embodiment, 2 end of handle is equipped with spherical portion 21.When operator operates the present apparatus, the end of operating handle
Portion can withstand on the palm of the hand of operator, and 2 end of handle is designed as spherical portion 21, more comfortable when end can be made to oppress the palm of the hand,
And spherical portion 21 prolongs palm of the hand sliding in operation, reduces friction, keeps operation more convenient comfortable.
