Abstract
The utility model discloses a kind of Flameproof box change over switch mechanism, comprise: a U-shaped bracing frame, change over switch and operating axis, the dual-side of described U-shaped bracing frame is corresponding the first concentric installing hole and the second installing hole of being provided with respectively, on described the first installing hole, be fixed with described change over switch, described operating axis runs through Flameproof box panel and described the second installing hole and is fixed on described the second installing hole by an adjusting nut.By the utilization of installing mechanism of the present utility model, guarantee the application simple installation of common change-over switches in Flameproof box, operation is reliable, exempts clamping stagnation, avoids misoperation; This installing mechanism reduces welding, reduces box deformation, can ensure that Flameproof box panel surface is smooth, has sprayed after paint smooth, attractive in appearance; This installing mechanism rotary type installing mechanism, arbitrary orientation is adjustable, is convenient to adjustment, wiring, maintenance; This installing mechanism is reasonable in design, simplifies production process, meets explosion-proof criteria requirement.
Description
Technical field
The utility model relates to a kind of Flameproof box change over switch mechanism.
Background technology
In the time that explosion-proof electric control box needs configuration transitions switch, the common change-over switches of Flameproof box panel rear side must adopt mounting bracket, and each mounting bracket must at least weld 4 screw brackets, when this 4 screw bracket welding, for ensureing positioning precision, must adopt shuttering supporting.And while adjusting change over switch actual functional capability after installing, must correspondingly adjust 4 screw rod height, guarantee panel peripheral operation switch is concentric with internal conversion switch rotary axle simultaneously, and flexible operation is reliable.If 4 supports are adjusted slightly deviation, just cause peripheral operation switch and internal conversion switch rotary axle decentraction, rotation clamping stagnation, causes switch contact loose contact, loses electric function.Because each change over switch must weld 4 supports, easily cause Flameproof box panel deformation, weldment external table appearance quality variation.
Utility model content
Because prior art exists the problems referred to above, the utility model proposes a kind of Flameproof box change over switch mechanism, it can effectively solve the problems referred to above of prior art.
The utility model addresses the above problem by the following technical programs:
One Flameproof box change over switch mechanism, comprise: a U-shaped bracing frame, change over switch and operating axis, the dual-side of described U-shaped bracing frame is corresponding the first concentric installing hole and the second installing hole of being provided with respectively, on described the first installing hole, be fixed with described change over switch, described operating axis runs through Flameproof box panel and described the second installing hole and is fixed on described the second installing hole by an adjusting nut.
Described operating axis is positioned on one end of described Flameproof box panels outside and has been bolted a console switch.
By the utilization of installing mechanism of the present utility model, guarantee the application simple installation of common change-over switches in Flameproof box, operation is reliable, exempts clamping stagnation, avoids misoperation; This installing mechanism reduces welding, reduces box deformation, can ensure that Flameproof box panel surface is smooth, has sprayed after paint smooth, attractive in appearance; This installing mechanism rotary type installing mechanism, arbitrary orientation is adjustable, is convenient to adjustment, wiring, maintenance; This installing mechanism is reasonable in design, simplifies production process, meets explosion-proof criteria requirement.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the present utility model.
Embodiment
Below in conjunction with embodiment, describe the utility model in detail.
Shown in Figure 1, be the structural representation of an embodiment of the present utility model.
The Flameproof box of the present embodiment comprises with change over switch mechanism: a U-shaped bracing frame 5, change over switch 6 and operating axis 3, the dual-side of described U-shaped bracing frame 5 is corresponding the first concentric installing hole 51 and the second installing hole 52 of being provided with respectively, on described the first installing hole, be fixed with described change over switch 6, described operating axis 3 runs through Flameproof box panel 1 and described the second installing hole 52 and is fixed on described the second installing hole by an adjusting nut 4.
Described operating axis is positioned on one end of described Flameproof box panels outside and has been bolted a console switch 2.Rotate operating axis by rotation console switch.
By the utilization of this installing mechanism, guarantee the application simple installation of common change-over switches in Flameproof box, operation is reliable, exempts clamping stagnation, avoids misoperation; This installing mechanism reduces welding, reduces box deformation, can ensure that Flameproof box panel surface is smooth, has sprayed after paint smooth, attractive in appearance; This installing mechanism rotary type installing mechanism, arbitrary orientation is adjustable, is convenient to adjustment, wiring, maintenance; This installing mechanism is reasonable in design, simplifies production process, meets explosion-proof criteria requirement.
Should be understood that these execution modes are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Claims (2)
