Description
Technical field
The utility model relates to a kind of spring erector, relates in particular to a kind of breaker open operation spring assembly erector.
Background technology
The modernization construction in cities and towns and the raising of living standards of the people make electricity needs is increased substantially, about statistics shows, and along with development of electric power industry, every year will be to the demand of moulded case circuit breaker with 15%～20% speed increase.Circuit breaker is the core component of low-tension switch cabinet, and its product level, workmanship directly influence Electrical Safety reliability, the production production equipment that has ensured the industrial cousumer and resident's the quality of life of industrial and mining enterprises, hospital, residential quarter etc.In the 0.69kV electric pressure, the use amount of moulded case circuit breaker accounts for more than 70% of circuit breaker total amount.The development of Model Case Circuit Breaker technology reaches its maturity both at home and abroad at present; But when assembling; Must turn round predetermined angular to one group of torsion spring, torsion reaches oxen up to a hundred, and can not destroy the preservative treatment layer on spring surface again; Because the circuit breaker inner space is little, reverse very difficulty to torsion spring in return mechanism inside.Therefore, the fixed contact return mechanism torsion spring of circuit breaker is assembled into the technological problems that restriction is in enormous quantities, streamline is produced.
Like Chinese patent publication number: CN101710550A; Open day: the patent of invention on May 19th, 2010 disclosed a kind of contact terminal assembling device of moulded case circuit breaker; It comprises the base plate of being with groove, can insert bottom plate groove and be connected main body and left and right sides piece, location-plate, back plate and two long sleeve pipes on it; Left and right sides piece is connected in the main body left and right sides and a piece protruding plate is arranged respectively, location-plate one end be connected on the main body other end be one upwards, the jagged plate of bending forward; The base plate front end has long spiro nail and at the end that links to each other with base plate locknut is arranged; The back plate of band square hole is set on the long spiro nail screw rod; Another locknut is fixed on long spiro nail nut one end with the back plate, and two long sleeve pipe one ends can insert the other end respectively not in the plate square hole of back with fixed contact spring wire two ends respectively.But this apparatus structure is complicated, and volume is bigger, can't realize quantitatively the reversing and installing of circuit breaker fixed contact return mechanism torsion spring, and can not guarantee the not damaged assembling of torsion spring surface anticorrosion processing layer.
Summary of the invention
The purpose of the utility model is to be not easy to assembling to existing circuit breaker fixed contact return mechanism torsion spring; Be difficult to both torsion spring was torqued into certain angle; Can not destroy the defective and the deficiency of torsion spring surface anticorrosion processing layer again; Provide a kind of simple in structure, be convenient to efficient assembling, can not destroy a kind of breaker open operation spring assembly erector of spring surface anticorrosion processing layer simultaneously again.
For realizing above-mentioned purpose; The technical solution of the utility model is: a kind of breaker open operation spring assembly erector; Comprise adding long handle, an end that adds long handle is a portion of the handle, and the said other end that adds long handle is provided with protruding fork; The centre of protruding fork longitudinally offers breach, and the upper surface symmetry of protruding fork offers the semicircle cambered surface.
The outer face of said protruding fork is the arc surface to outer process.
The lower surface of said protruding fork is a lower plane, the contact-making surface transitions smooth of lower plane and arc surface.
The beneficial effect of the utility model is:
1. the utility model is provided with protruding fork at an end that adds long handle, and the centre of protruding fork longitudinally offers breach, and the upper surface symmetry of protruding fork offers the semicircle cambered surface, torsion spring is tangled and utilizes lever principle torsion spring is quantitatively reversed through the semicircle cambered surface.
2. the utility model is simple in structure; Time saving and energy saving, easy to assembly and efficient is high, can realize quantitatively reversing to circuit breaker fixed contact return mechanism torsion spring; And can realize not damaged assembling, be suitable for pipelining in enormous quantities torsion spring surface anticorrosion processing layer.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the vertical view of the utility model.
Among the figure: arc surface 1, lower plane 2, semicircle cambered surface 3 adds long handle 4, protruding fork 5.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further to describe in detail.
Referring to Fig. 1, Fig. 2; A kind of breaker open operation spring assembly erector of the utility model; Comprise adding long handle 4, an end that adds long handle 4 is a portion of the handle, and the said other end that adds long handle 4 is provided with protruding fork 5; The centre of protruding fork 5 longitudinally offers breach, and the upper surface symmetry of protruding fork 5 offers semicircle cambered surface 3.
The outer face of said protruding fork 5 is the arc surface 1 to outer process.
The lower surface of said protruding fork 5 is a lower plane 2, the contact-making surface transitions smooth of lower plane 2 and arc surface 1.
An end that adds long handle 4 is a portion of the handle, and the other end that adds long handle 4 is provided with protruding fork 5, and the centre of protruding fork 5 longitudinally offers breach, makes the left and right sides of breach that a convexity arranged respectively, referring to Fig. 2.The upper surface symmetry of protruding fork 5 offers semicircle cambered surface 3; Semicircle cambered surface 3 can play the effect that torsion spring is tangled and locatees when the assembling torsion spring; Make torsion spring in twist process, can not come off; And semicircle cambered surface 3 can play a protective role to the anticorrosive coat on torsion spring surface in mounting the torsion spring process, is not easy to cause damage.The outer face of protruding fork 5 is the arc surface 1 to outer process, and the lower surface of protruding fork 5 is a lower plane 2, and the contact-making surface transitions smooth of lower plane 2 and arc surface 1 is convenient to when inserting spring mechanism inside, avoid damaging mechanism and inner other parts.
The method for using of the utility model is following: the front end with the utility model is inserted into moulded case circuit breaker torsion spring installation position inner to be installed earlier; Then one group of torsion spring of circuit breaker fixed contact return mechanism is inserted in respectively on the semicircle cambered surface 3 of the utility model front end; Pull subsequently and add long handle 4; And be fulcrum with lower plane 2, lower plane 2 is shelved on the inside of circuit breaker, utilizes lever principle can reach the labour-saving effect; Make moulded case circuit breaker fixed contact return mechanism torsion spring quantitatively reverse, realized the not damaged of torsion spring and assembling fast.
