Abstract
The utility model discloses a ground switch bevel gear mechanism which comprises a main gear and a gear base, wherein the main gear is arranged on the frontage of the gear base through a shaft sleeve the interior of which is hollow, and the inner wall of the shaft sleeve is provided with a lug along an axial direction; and the two sides of the gear base are provided with equipment gears, and the equipment gears are in transmission connection with the main gear. The ground switch bevel gear mechanism provided by the utility model adopts a gear with the shaft sleeve, the use is convenient, and the operation is safe; and when a ground switch is switched on, the switch is instantly closed, firstly, the shaft sleeve of a gear center is driven, and an operating handle is not driven, the generation of safe accidents is effectively avoided, and the service life of equipment is also prolonged.
Description
Technical field
The utility model relates to a kind of earthed switch bevel gear mechanism.
Background technology
Earthed switch is the mechanical switch that is used for the circuit ground part, belongs to the isolating switch classification, and it can carry the electric current under the non-normal condition within a certain period of time.And existing earthed switch closing operation comes transmission through the action bars driven gear, and during combined floodgate, the movable touch knife of earthed switch and fixed contact are through the spring return; When earthed switch closes a floodgate, the elastic force abrupt release of spring, driven gear and action bars make action bars answer speed very fast, and so not only there is very big influence in the life-span to machinery, and security incident very easily takes place, and impels the staff injured.
The utility model content
The utility model is in order to overcome the deficiency of prior art, and a kind of handling safety, earthed switch bevel gear mechanism easy to use are provided.
To achieve these goals, the utility model adopts following technical scheme: a kind of earthed switch bevel gear mechanism, comprise master gear and pinion stand, and master gear is located at the place ahead of pinion stand through the axle sleeve of inner hollow, and the inwall axis oculi of axle sleeve is to being provided with projection; The both sides of pinion stand are provided with equipment gear, and equipment gear and master gear are in transmission connection.
As preferably, the rearward end of said axle sleeve is provided with a circle groove, is provided with the snap ring of an opening in this groove.
As preferably, said equipment gear is provided with steel bushing in the front portion, has the hexagonal through hole in the steel bushing.
The utlity model has following advantage: the utility model adopts the gear of tape spool cover, and is easy to use, handling safety; When earthed switch closed a floodgate, switch moment was closed, axle sleeve that at first can the driven gear center, and do not drive operating grip, and effectively avoid the generation of complete accident, also prolonged the useful life of equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the STRUCTURE DECOMPOSITION sketch map of the utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, complete description; Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
Like Fig. 1, shown in Figure 2, a kind of earthed switch bevel gear mechanism comprises master gear 7 and pinion stand 1, and master gear 7 is located at the place ahead of pinion stand 1 through the axle sleeve 5 of inner hollow, and the inwall axis oculi of axle sleeve 5 is to being provided with projection 52; The both sides of pinion stand 1 are provided with equipment gear 2, and equipment gear 2 is in transmission connection with master gear 7.The rearward end of axle sleeve 5 is provided with a circle groove 51, is provided with the snap ring 4 of an opening in this groove 51.Equipment gear is provided with steel bushing 3 in 2 front portions, has hexagonal through hole 31 in the steel bushing 3.During use, action bars is inserted in the hexagonal through hole in the steel bushing 3, earthed switch rotating shaft insert in the axle sleeve of master gear; During contact of earth, the twist operation bar, equipment gear drives master gear and rotates; Then drive the rotating shaft action of earthed switch, earthed switch moment is closed, the axle sleeve that its spring at first can the driven gear center; And do not drive operating grip, effectively avoid the generation of complete accident; Also protect and prolonged the useful life of entire equipment.
