Abstract
The invention relates to a propulsion device of a primary contact of a low-voltage switch cabinet, which comprises a rack 7, a transverse square bar 4, a longitudinal square bar 6, a straight-toothed gear 3, a longitudinal angular wheel 5 and a transverse angular wheel 8, wherein the transverse square bar 4 and the longitudinal square bar 6 are fixed on a drawer body and can rotate along an axial direction, the longitudinal angular wheel 5 is fixed at the end part of the longitudinal square bar 6, the transverse angular wheel 8 is fixed at the middle part of the transverse square bar 4, the modulus of the longitudinal angular wheel 5 is the same as the modulus of the transverse angular wheel 8, the straight-toothed gear 3 is fixedly distributed on the transverse square bar 4, and the rack 7 is matched and engaged with the straight-toothed gear 3; and the transverse square bar 4 and the longitudinal square bar 6 are vertically installed at 90 degrees, so that the longitudinal angular wheel 5 and the transverse angular wheel 8 are engaged. When one end of the longitudinal square bar 6 is installed, one end of the longitudinal square bar 6 exposes out of the end face of the drawer, and the rack 7 is fixedly connected with a pin box of a movable 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 the control appliance, belong to the low voltage electrical apparatus technology field.
Background technology
In standard GB 7251.1-2005 " low-voltage complete switch equipment and control appliance " and the JB9661-1999 standard criterions such as " low pressure pull-out type switchgear assemblies ", all regulation pull-out type low-voltage complete equipment must have connection, tests and separate three location statuss, main circuit (comprising inlet wire and outlet) at the test position functional unit separates with power supply, and the secondary auxiliary circuit still is in connection status, and cell gate can not be opened when requiring test position, does not reduce the shell protection grade.In order to adapt to new national standard, each manufacturer improves design on the basis of original mechanism, for example known China Patent No. be 03240748.3 and be called " low pressure drawer-type switch cabinet propulsive mechanism " though the utility model patent specification in disclosed propulsive mechanism can satisfy the requirement that test position is not opened the door, but it is moving, the connection of fixed contact or separation, needing to drive whole drawer body moves, owing in the drawer body of low-tension switch cabinet other electric component is installed also, electric component with the drawer body move with, so electric component unavoidably produces vibration in moving process on the one hand, the drawer deadweight also can cause relatively effort of turnover operation on the other hand.For example known again China Patent No. be 200410064770.9 be called " movable propelling continuous drawer function unit " though the patent of invention specification in the dynamic and static contact of disclosed propulsive mechanism connection or separate 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, 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 guarantee that cell gate is not opened when testing the position, and need not drive whole drawer body, can realize that a main circuit (comprising inlet wire and outlet) separates and connection status with power supply, guarantees 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, vertical square bar, straight-tooth gear, vertical angular wheel and lateral taper gear, laterally square bar, vertical square bar are fixed on the drawer body and can rotate vertically, vertically angular wheel is fixed in vertical square bar end, the lateral taper gear is fixed in horizontal square bar middle part, vertically angular wheel is identical with the lateral taper module, the straight-tooth gear stationary distribution on horizontal square bar, the supporting engagement of tooth bar and straight-tooth gear; Laterally square bar becomes 90 to spend vertical installation with vertical square bar, makes vertical angular wheel and lateral taper gears engaged.Vertically an end of square bar exposes to the drawer end face when mounted, and tooth bar is fixedlyed connected with the pin box of moving contact.
The present invention rotates vertical square bar by rocking handle when operation, vertically angular wheel rotates with vertical square bar, driving the lateral taper gear simultaneously rotates, laterally square bar, gear rotate synchronously with the lateral taper gear, gear pulling tooth bar moving linearly, thereby the pin box that promotes moving contact advances or retreats, and promptly realizes deciliter action of moving contact and fixed contact under the situation of not opening cell gate.
Number of spare parts of the present invention is few, and structure is simple for assembly process, and will axially rotatablely move by the conical tooth wheels is converted into the rectilinear motion of fore-and-aft direction, need not open during operation the drawer unit door can realize dynamic/static contact deciliter, handling safety, laborsaving.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The present invention is further described below in conjunction with accompanying drawing.
Among the figure: 3, straight-tooth gear 4, horizontal square bar 5, conical tooth wheels 6, vertical 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, vertical square bar 6, straight-tooth gear 3, vertical angular wheel 5 and lateral taper gear 8, laterally square bar 4, vertical square bar 6 are fixed on the drawer body and can rotate vertically, vertically angular wheel 5 is fixed in vertical square bar 6 ends, lateral taper gear 8 is fixed in horizontal square bar 4 middle parts, vertically angular wheel 5 is identical with lateral taper gear 8 moduluses, straight-tooth gear 3 stationary distribution on horizontal square bar 4, tooth bar 7 and straight-tooth gear 3 supporting engagements; Laterally square bar 4 and the vertically vertical installation of 6 one-tenth 90 degree of square bar make vertical angular wheel 5 and lateral taper gear 8 mesh.Vertically an end of square bar 6 exposes to the drawer end face when mounted, and tooth bar 7 is fixedlyed connected with the pin box of moving contact.
The present invention rotates vertical square bar 6 by rocking handle when operation, vertically angular wheel 5 is with vertical square bar 6 rotations, drive 8 rotations of lateral taper gear simultaneously, laterally square bar 4, gear 3 rotate synchronously with lateral taper gear 8, pulling tooth bar 7 moving linearlies during gear 3 rotations, thereby the pin box that promotes moving contact advances or retreats, and promptly realizes deciliter action of moving contact and fixed contact under the situation of not opening cell gate.
