The primary contact propulsion device comprises racks 7, a transverse square bar 4, a longitudinal square bar 6, straight-toothed gears 3, a longitudinal bevel gear 5 and a transverse bevel gear 8, wherein the transverse square bar 4 and the longitudinal square bar 6 are fixed on a drawer body and can rotate in the axial direction; the longitudinal bevel gear 5 is fixed at one end part of the longitudinal square bar 6; the transverse bevel gear 8 is fixed in the middle of the transverse square bar 4; the longitudinal bevel gear 5 has the same modulus as the transverse bevel gear 8; the straight-toothed gears 3 are fixedly distributed on the transverse square bar 4; the racks 7 and the straight-toothed gears 3 are meshed in a matched manner; the transverse square bar 4 and the longitudinal square bar 6 are perpendicular to each other, so that the longitudinal bevel gear 5 and the transverse bevel gear 8 are meshed; during installation, one end of the longitudinal square bar 6 is exposed outside the end surface of the drawer, and 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 be separated three location statuss, be separated with power supply at a main circuit (comprising inlet wire and outlet) of test position functional unit, and secondary auxiliary circuit is still in connection status, and cell gate can not be opened when requiring test position, do not reduce shell protection grade.In order to adapt to new national standard, each manufacturer carries out Curve guide impeller 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 do not open the door, but it is dynamic, the connection of fixed contact or separation, need to drive whole drawer body to move, owing to being also provided with other electric component in the drawer body of low-tension switch cabinet, electric component with drawer body mobile with, so one side electric component in moving process unavoidably produces vibration, drawer deadweight also can cause turnover to operate and compare effort 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 disclosed dynamic and static contact of propulsive mechanism connection or be separated and 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, there is provided a kind of structure simple, 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 when testing position, and whole drawer body need not be driven, a main circuit (comprising inlet wire and outlet) can be realized and be separated and connection status with power supply, guarantee the degree of protection requirement of switchgear.
The technical scheme solving the employing of its technical problem 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, horizontal square bar, longitudinal square bar are fixed on drawer body and also can rotate vertically, longitudinal angular wheel is fixed on longitudinal square bar end, lateral taper gear is fixed in the middle part of horizontal square bar, longitudinal 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; Horizontal square bar becomes 90 degree of at right angle settings with longitudinal square bar, makes longitudinal angular wheel and lateral taper gears meshing.One end of longitudinal 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 when operating by rocking handle, longitudinal angular wheel rotates together with longitudinal square bar, drive lateral taper pinion rotation simultaneously, horizontal square bar, gear rotate with lateral taper gear synchronous, gear pulls tooth bar moving linearly, thus the pin box promoting moving contact advances or retreats, and namely realizes deciliter action of moving contact and fixed contact when not opening cell gate.
Number of spare parts of the present invention is few, and structure is simple for assembly process, by conical tooth wheels, axial rotation motion is converted into the rectilinear motion of fore-and-aft direction, during operation need not drawing-out type drawer cell gate can realize dynamic/static contact deciliter, handling safety, laborsaving.
Accompanying drawing explanation
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, horizontal square bar 4, longitudinal square bar 6 are fixed on drawer body and also can rotate vertically, longitudinal angular wheel 5 is fixed on longitudinal square bar 6 end, lateral taper gear 8 is fixed in the middle part of horizontal square bar 4, longitudinal angular wheel 5 is identical with lateral taper gear 8 modulus, straight-tooth gear 3 stationary distribution is on horizontal square bar 4, and tooth bar 7 engages with straight-tooth gear 3 is supporting; Horizontal square bar 4 and longitudinal square bar 6 one-tenth 90 degree of at right angle settings, make longitudinal angular wheel 5 engage with lateral taper gear 8.One end of longitudinal 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 when operating by rocking handle, longitudinal angular wheel 5 rotates together with longitudinal square bar 6, drive lateral taper gear 8 to rotate simultaneously, horizontal square bar 4, gear 3 are with lateral taper gear 8 synchronous rotary, gear 3 pulls tooth bar 7 moving linearly when rotating, thus the pin box promoting moving contact advances or retreats, and namely realizes deciliter action of moving contact and fixed contact when not opening cell gate.
