Abstract
The invention relates to a primary contact propelling device of a low-voltage switch cabinet. The primary contact propelling device comprises racks 7, a transverse square rod 4, a longitudinal square rod 6, straight-tooth gears 3, a longitudinal bevel gear 5 and a transverse bevel gear 8. The transverse square rod 4 and the longitudinal square rod 6 are fixed to a drawer body and can rotate in the axial direction. The longitudinal bevel gear 5 is fixed to one end of the longitudinal square rod 6. The transverse bevel gear 8 is fixed to the middle of the transverse square rod 4. The modulus of the longitudinal bevel gear 5 is the same as that of the transverse bevel gear 8. The straight-tooth gears 3 are fixedly distributed on the transverse square rod 4. The racks 7 are matched and meshed with the straight-tooth gears 3. The transverse square rod 4 and the longitudinal square rod 6 are perpendicularly arranged to form a 90-degree angle so that the longitudinal bevel gear 5 can be meshed with the transverse bevel gear 8. One end of the longitudinal square rod 6 is exposed out of one end face of a drawer in the installation process. The racks 7 are fixedly connected with a pin box of a moving contact.
Description
Technical field
The present invention relates to a kind of propulsion device of primary contact of low-voltage switch cabinet in low-voltage complete switch equipment and control appliance, belong to low voltage electrical apparatus technology field.
Background technology
In the standard criterions such as standard GB/T 7251.1-2005 " low-voltage complete switch equipment and control appliance " and JB9661-1999 " low-voltage drawing switch apparatus ", all regulation pull-out type low voltage complete set must have connection, test and separate three location statuss, a main circuit (comprising inlet wire and outlet) at test position functional unit separates with power supply, and secondary auxiliary circuit is still in connection status, and cell gate can not be opened while requiring test position, does not reduce shell protection grade.In order to adapt to new national standard, each manufacturer improves design on the basis of original mechanism, example as is known China Patent No. be 03240748.3 be called " propelling device for low voltage drawer type switch cubicle " although utility model patent specification in disclosed propulsive mechanism can meet the requirement that test position is not opened the door, but moving, the connection of fixed contact or separation, the whole drawer body of demand motive moves, in drawer body due to low-tension switch cabinet, other electric component is also installed, electric component with drawer body mobile with, so in moving process, electric component unavoidably produces vibration on the one hand, drawer deadweight also can cause relatively effort of turnover operation on the other hand.Again example as is known China Patent No. be 200410064770.9 be called " movable propelling continuous drawer function unit " although patent of invention specification in the dynamic and static contact of disclosed propulsive mechanism connection or separate need not drive whole drawer body, but mechanism design is too complicated, bulky.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of simple in structure, laborsaving, fltting speed is fast, accurate positioning, the propulsion device of primary contact of low-voltage switch cabinet that anti-error performance is good, can ensure that cell gate is not opened in the time testing position, and need not drive whole drawer body, can realize a main circuit (comprising inlet wire and outlet) and separate and connection status with power supply, guarantee the degree of protection requirement of switchgear.
The technical scheme that solves its technical problem employing is: design a kind of propulsion device of primary contact of low-voltage switch cabinet, comprise tooth bar, horizontal square bar, longitudinal square bar, straight-tooth gear, longitudinal angular wheel and lateral taper gear, laterally square bar, longitudinal square bar are fixed on drawer body and can rotate vertically, longitudinally angular wheel is fixed on longitudinal square bar end, lateral taper gear is fixed on horizontal square bar middle part, longitudinally angular wheel is identical with lateral taper module, straight-tooth gear stationary distribution is on horizontal square bar, and tooth bar engages with straight-tooth gear is supporting; Laterally square bar becomes 90 degree at right angle settings with longitudinal square bar, and longitudinal angular wheel is engaged with lateral taper gear.Longitudinally one end of square bar exposes to drawer end face when mounted, and tooth bar is fixedly connected with the pin box of moving contact.
The present invention rotates longitudinal square bar by rocking handle in the time of operation, longitudinally angular wheel rotates together with longitudinal square bar, drive lateral taper gear to rotate simultaneously, laterally square bar, gear rotate with lateral taper gear synchronous, gear pulls tooth bar moving linearly, thereby the pin box that promotes moving contact advances or retreats, and realizes deciliter action of moving contact and fixed contact in the situation that not opening cell gate.
Number of spare parts of the present invention is few, and structure is simple for assembly process, the rectilinear motion that is fore-and-aft direction by axial-rotation conversion of motion by conical tooth wheels, need not drawing-out type drawer cell gate when operation can realize dynamic/static contact deciliter, handling safety, laborsaving.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Below in conjunction with accompanying drawing, the present invention is further described.
In figure: 3, straight-tooth gear 4, horizontal square bar 5, conical tooth wheels 6, longitudinal square bar 7, tooth bar 8, lateral taper gear.
Embodiment
As shown in the figure, propulsion device of primary contact of low-voltage switch cabinet of the present invention, comprise tooth bar 7, horizontal square bar 4, longitudinal square bar 6, straight-tooth gear 3, longitudinal angular wheel 5 and lateral taper gear 8, laterally square bar 4, longitudinal square bar 6 are fixed on drawer body and can rotate vertically, longitudinally angular wheel 5 is fixed on longitudinal square bar 6 ends, lateral taper gear 8 is fixed on horizontal square bar 4 middle parts, longitudinally angular wheel 5 is identical with lateral taper gear 8 moduluses, straight-tooth gear 3 stationary distribution are on horizontal square bar 4, and tooth bar 7 engages with straight-tooth gear 3 is supporting; Laterally square bar 4 and longitudinal 6 one-tenth 90 degree at right angle settings of square bar, make longitudinal angular wheel 5 engage with lateral taper gear 8.Longitudinally one end of square bar 6 exposes to drawer end face when mounted, and tooth bar 7 is fixedly connected with the pin box of moving contact.
The present invention rotates longitudinal square bar 6 by rocking handle in the time of operation, longitudinally angular wheel 5 rotates together with longitudinal square bar 6, drive lateral taper gear 8 to rotate simultaneously, laterally square bar 4, gear 3 are with lateral taper gear 8 synchronous rotaries, gear 3 pulls tooth bar 7 moving linearlies while rotation, thereby the pin box that promotes moving contact advances or retreats, and realizes deciliter action of moving contact and fixed contact in the situation that not opening cell gate.
