Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the Mume flower contact that provides of the utility model embodiment more changing device;
Wherein: 1 handle, 2 straight-bars, 3 garter springs, 31 draw-in grooves, 4 buckles.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
As shown in Figure 1, the utility model embodiment provides a kind of Mume flower contact more changing device, described Mume flower contact more changing device comprises: the garter spring 3 of handle 1, straight-bar 2, opening and buckle 4, described handle 1 is fixedly connected with the first end of described straight-bar 2, second end of described straight-bar 2 is located in described buckle 4, and be flexibly connected with described buckle 4, the first end of described garter spring 3 is fixedly connected with described buckle 4, and the second end of described garter spring 3 is through described buckle 4 and to described buckle 4 extension;
Second end of described straight-bar 2 is provided with helical tooth, described straight-bar 2 can rotate in described buckle 4, described garter spring 3 is circumferentially provided with the draw-in groove 31 of multiple equidistant arrangement, multiple described draw-in groove 31 engages with the helical tooth on described straight-bar 2 is staggered, and the second end of described garter spring 3 can move relative to described buckle 4.
Wherein, one end that garter spring 3 is connected for the fixed contact being sleeved on Mume flower contact and cable side or bus bar side, when this end of Mume flower contact shrinks, its other end then can open, and one end that namely Mume flower contact is connected with the contact arm on circuit breaker trolley is opened.
Handle 1 is connected with the first end of straight-bar 2, for rotating straight-bar 2, second end of straight-bar 2 is provided with helical tooth and can rotates in buckle 4, this helical tooth coordinates with multiple draw-in grooves 31 that garter spring 3 circumferentially arranges, form worm-drive form, namely the rotation of straight-bar 2 can make draw-in groove 31 on garter spring 3 at this helical tooth upper driving, second end of the garter spring 3 be flexibly connected with buckle 4 can be stretched out relative to buckle 4, and be fixed on buckle 4 due to the first end of garter spring 3, therefore, when straight-bar 2 rotates, the diameter of garter spring 3 can reduce to buckle 4 extension with the second end of garter spring 3, thus make one end banding that the fixed contact of Mume flower contact and cable side or bus bar side is connected by garter spring 3, this end of Mume flower contact is shunk, thus force the other end of Mume flower contact, i.e. one end of being connected with the contact arm on circuit breaker trolley of Mume flower contact, open gradually, until its internal diameter is greater than the diameter with the contact arm of its clamping, then this Mume flower contact easily can be taken off from contact arm, complete dismounting, in like manner, also can be overlapped gently by new Mume flower contact installs on contact arm again, complete installation.
In said process, because the spring coil at Mume flower contact two ends is all positioned at the outside of each contact finger piece all the time and retrains each contact finger piece, therefore, when operating, each contact finger piece is not easily scattered, decrease troublesome poeration, make dismounting and fitting operation all more simple and convenient, by one man operation, and the used time is shorter, compared with each operation of prior art all time-consuming at least half an hour, the utility model on average to operate when only costing about ten minutes at every turn, decrease the used time of about 2/3rds and the manpower of half, substantially increase efficiency of construction, and, because the used time shortens, then shorten the time had a power failure because changing Mume flower contact accordingly, improve power transmission efficiency, in addition, when using the utility model, Mume flower contact not easily sustains damage, and avoids the potential safety hazard caused because of Mume flower contact damage, also serves protective effect to the miscellaneous equipment in high-tension switch cabinet.
Alternatively, described garter spring 3 is the elastic steel sheet of bar shaped.
As shown in Figure 1, particularly, multiple described draw-in groove 31 is in turn along the length direction equidistant arrangement of described elastic steel sheet, and each described draw-in groove 31 is all arranged along the Width of described elastic steel sheet.
Wherein, the elastic steel sheet of bar shaped has certain elasticity, can turn around into garter spring 3, and elastic steel sheet also has bending resistance, can make garter spring 3 retaining ring shape state, be convenient to cover and install on Mume flower contact; On elastic steel sheet, multiple draw-in grooves 31 of its length direction equidistant arrangement suitable are for coordinating with the helical tooth on the second end of straight-bar 2, when straight-bar 2 rotates in buckle 4, each draw-in groove 31 just on helical tooth along the axial transmission of straight-bar 2, first end and the buckle 4 of elastic steel sheet are fixed, its second end just extends outside buckle 4 along with the rotation of straight-bar 2, makes garter spring 3 reduced; Multiple draw-in groove 31 preferentially can be arranged on the part near its second end on elastic steel sheet, and can not arrange draw-in groove 31 near the part of its first end, reduces the amount of labour of processing garter spring 3.
Further, the diameter of described garter spring 3 is 45mm-170mm.
Alternatively, the width of described garter spring 3 is 12mm or 14.2mm.
Wherein, garter spring 3 selects this diameter dimension and width dimensions, can be applicable to the Mume flower contact in most high-tension switch cabinet, have general applicability; Width also can be 8mm, 12.7mm equidimension, and the size of garter spring 3 can be selected flexibly according to the specification of Mume flower contact.
Alternatively, described handle 1 and described straight-bar 2 are steel pole.
As shown in Figure 1, further, described handle 1 is vertical with described straight-bar 2 and be welded to connect.
Wherein, handle 1 and straight-bar 2 all preferably diameter are greater than the conventional steel pole of 8mm, and handle 1 perpendicular to straight-bar 2, and welds with the first end of straight-bar 2 in the middle part of handle 1, the intensity ensureing handle 1 and straight-bar 2 and the steadiness be connected, the rotation process of straight-bar 2 is convenient in the setting of handle 1.
Particularly, described garter spring 3, described buckle 4 are stainless steel material.
Wherein, stainless steel material is widely used, and intensity is higher, use the garter spring 3 of this materials processing and buckle 4 durable; The utility model has that volume is little, lightweight, structure is simple, processing and fabricating is easy, with low cost, use the advantages such as quick, allot to i.e. replaceable good Mume flower contact very soon after maintainer, have efficient, advantage reliably, practical value is remarkable.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
