Abstract
The utility model provides a transfer switch device. In order to solve the problems of inconvenient turning and being locked and damaged easily of the former transfer switch, the utility model discloses a transfer switch device used for an explosion-proof electric device, which comprises an iron jacket, a copper jacket, a core, a spring, a pedestal, a pin and an indicating mark. The iron jacket is fixed at the casing of the device. The copper jacket is pressed and installed inside the iron jacket to be fixed. One end of the core is limited and fastened by a pin, and the other end is matched inside the copper jacket. The spring is installed inside a space between the core and the copper jacket, so as to solve the problem that the former button is locked easily.
Description
Technical field
The utility model relates to the Coal Mechanical field, particularly a kind of transfer switch unit of mining equipment.
Background technology
In the flame proof product of prior art, if use change over switch in the product, need be installed in the change over switch button in the housing, want the commutation of control transformation switch, will externally set up conversion equipment, there is multiple deficiency in these transfer switch units at present, mainly contain the following aspects: it is loosening to fall lacquer easily; Stuck easily; With easy wearing and tearing dislocation of a specified duration etc.
Summary of the invention
The utility model purpose is to address the above problem, and a kind of transfer switch unit is provided, and it can increase the flexibility of transfer switch unit, thus the equipment of solution explosion insulation performance and problem stuck easily and the wearing and tearing dislocation.
The utility model adopts following technical scheme to solve technical problem:
A kind of transfer switch unit, comprise iron cover, copper sheathing, core, spring, pin, base and indicateing arm, it is characterized in that the iron cover is fixed on the shell of equipment, copper sheathing pressure-mounting is fixing in the iron cover, one end of core is fastening by pin and base, the other end is engaged in the copper sheathing, and spring is installed in the neutral gear between core and copper sheathing.The core other end is engaged in the copper sheathing, and this end cooperates with copper sheathing, makes core not expose copper sheathing and iron cover.The fit system of copper sheathing pressure-mounting in the iron cover is interference fit.
Compared with prior art, the utlity model has following advantage:
The utility model is on the basis of conventional design, best mode is to have adopted the scheme that the iron cover is fixing and copper sheathing cooperates, earlier with copper sheathing and iron cover interference fit, both are fixed together, copper sheathing adds accurately to be processed man-hour, so both reached requirement of explosion, wear intensity is reduced, again the iron cover directly is welded on the shell of equipment, plays fixation, the neutral gear place shock mount in the middle of core and copper sheathing, play the possibility that relaxes transfer switch unit rotation and translation, this kind is simple in structure, science has solved the irrational place of conventional conversion switching device, and is simple in structure, compact, easy to operate, dismounting, assembling speed is fast etc.
Description of drawings
Fig. 1 is the profile of transfer switch unit structure of the present utility model
1, iron cover 2, copper sheathing 3, core 4, spring 5, pin 6, base 7, indicateing arm
Embodiment
A kind of transfer switch unit comprises iron cover 1, copper sheathing 2, core 3, spring 4, pin 5, base 6 and indicateing arm 7, and iron cover 1 is fixed on the shell of equipment, and copper sheathing 2 is fitted in the iron cover 1 fixing; One end of core 3 is fastening by pin 5 and base 6, and the other end is engaged in the copper sheathing 2; Spring 4 is installed in the neutral gear of 2 of core 3 and copper sheathings, and iron cover 1 is welded on the shell of equipment, and copper sheathing 2 is fitted in the iron cover 1 by interference fit.
Neutral gear place shock mount 4 in the middle of core 3 and the copper sheathing 2 plays the possibility that relaxes transfer switch unit rotation and translation.
Embodiment 1:
Transfer switch unit as shown in Figure 1 comprises iron cover 1, copper sheathing 2, core 3, spring 4, pin 5, base 6 and indicateing arm 7, and iron cover 1 is fixed on the shell of equipment, and copper sheathing 2 is fitted in the iron cover 1 fixing; One end of core 3 is fastening by pin 5 and base 6, and the other end is engaged in the copper sheathing 2; Spring 4 is installed in the neutral gear of 2 of core 3 and copper sheathings.
During making, earlier copper sheathing 2 and iron are overlapped 1 interference fit, both are fixed together, copper sheathing 2 adds accurately to be processed man-hour, has so both reached requirement of explosion, and wear intensity is reduced, and iron cover 1 directly is welded on the shell of equipment again, plays fixation.The structure of the iron cover 1 here is a boss structure, just is stuck in the circular hole that cuts on the device housings, plays location and fixing effect.
One end of core 3 is fastening by pin 5 and base 6, and the other end is engaged in the copper sheathing 2; Spring 4 is installed in the neutral gear of 2 of core 3 and copper sheathings, and spring plays and relaxes that transfer switch unit rotates and the possibility of translation.
Embodiment 2:
A kind of transfer switch unit comprises iron cover 1, copper sheathing 2, core 3, spring 4, pin 5, base 6 and indicateing arm 7, and iron cover 1 is fixed on the shell of equipment, and copper sheathing 2 is fitted in the iron cover 1 fixing; One end of core 3 is fastening by pin 5 and base 6, and the other end is engaged in the copper sheathing 2; Spring 4 is installed in the neutral gear of 2 of core 3 and copper sheathings.
Iron cover 1 can not be the structure of boss, and core structure also can satisfy the requirement of this transfer switch unit.
