The screw in dress hole, which screws in fixed support portion screw hole, locks and is reliably mounted on the rear end of main casing；The front panel installation
In preceding escutcheon, the preceding escutcheon is installed in the open front of main casing.
Be in place of above scheme Shortcomings: it is tight that the electric instrument passes through multiple screw and nut connections on the shell
Gu installing and dismounting get up it is very inconvenient, often disassembly be also easy to cause nut wear sliding teeth, the nut after abrasion can only be more
It changes, increases the workload of staff；And electric instrument mostly uses ventilative first through hole for radiating on the shell, due to saturating
Gas first through hole is difficult to ensure complete heat dissipation, it may appear that electric instrument internal temperature increases, and is easy to cause electric instrument failure.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of detachable electric instrument, and the electric instrument is logical
Cross the design of simple structure, can be fixed without screw, it is easy for assemble or unload quick, and the electric instrument heat dissipation effect compared with
It is good.
The technical solution of the utility model are as follows:
Detachable electric instrument, it is characterised in that: it includes preceding escutcheon and electric instrument main body, the preceding escutcheon right side
Equipped with opening, the preceding escutcheon includes inside casing and outline border, is equipped with inside casing, connection type are as follows: the inside casing inside the outline border
It is affixed with outline border left end inner wall by welding outside left end；The inside casing side wall is equipped with the first through hole of rectangle, and the outline border is set
There is the second through-hole corresponding with first through hole；Hollow on the left of the electric instrument main body, the electric instrument main body wall is equipped with
Third through-hole corresponding with first through hole, the inside casing of escutcheon before being embedded just below at hollow open on the left of the electric instrument main body
Between outline border, the electric instrument main body and preceding escutcheon are real by strip insertion first through hole, the second through-hole and third through-hole
Now fix.
Further, the outer end of the strip is welded with hanging ring, is equipped with arc groove on the outside of the strip, in the groove
Equipped with pressure-sensitive rubber mat, pressure-sensitive rubber mat effect is: when strip blocks electric instrument main body and preceding escutcheon, due to electric instrument master
Body and preceding escutcheon are not fixed structures, and electric instrument main body can loosen above and below preceding escutcheon, and strip drops out preceding escutcheon in order to prevent,
Therefore it is further fastened in electric instrument main body and preceding escutcheon using pressure-sensitive rubber mat, when electric instrument main body is loose on preceding escutcheon
Biggish pressure will be generated when dynamic, pressure-sensitive rubber mat can fixation electric instrument main body tightly and preceding escutcheon；The effect of hanging ring
Be: when electric instrument disassembly, hanging ring, which facilitates, pulls out strip.
Further, the electric instrument main body wall is additionally provided with multiple thermal vias, the electric instrument main body outside
Thermal dispersant coatings are coated with, its role is to: accelerate the heat dissipation effect of thermal vias；The material of the thermal dispersant coatings is a kind of heat dissipation
Coating, preparation method are shown in that Chinese patent discloses a kind of heat radiation coating, application No. is: 201610599486.4, the applying date are as follows:
2016.07.28。
The utility model has the following beneficial effects: the electric instrument body frame face of the utility model is equipped with several equidistantly
Thermal vias, the heat-radiation coating bed of material is coated with by the outer end face in electric instrument body frame face, it is logical can effectively to accelerate heat dissipation
The heat dissipation effect in hole effectively prevent electric instrument internal temperature to increase, leads to electric instrument failure；And use strip by electric power
Meter body and preceding escutcheon are fixed, and instead of the fixed form of screw rod and nut, effectively accelerate the speed of disassembly electric instrument
With the workload for effectively reducing staff.
