Abstract
The utility model relates to a kind of locking device be applied on frequency converter, described frequency converter comprises shell, described locking device is arranged at shell of frequency converter place, described locking device comprises lock piece and opening tool, described inner surface of outer cover and opening tool corresponding position are provided with lock piece, described opening tool and outer surface of outer cover are flexibly connected, and described lock piece is fixedly connected with inner surface of outer cover.The setting of opening tool and lock piece can well be opened and locking this frequency converter, and opening tool overcomes technology prejudice in the past, have employed movable, like this when frequency converter opened by needs, loaded by opening tool, when not needed, opening tool also can be taken out, both ensure that frequency converter did not increase relative volume, and also facilitated people and this frequency converter opens or cuts out.
Description
Technical field
The utility model relates to the device on a kind of frequency converter, and especially a kind of person easy to use opens the locking device on the frequency converter of shell of frequency converter.
Background technology
Frequency converter (Variable-frequency Drive, VFD) is application converter technique and microelectric technique, controls the electric control appliance of ac motor by changing machine operation supply frequency mode.Frequency converter is primarily of the composition such as rectification (AC-DC), filtering, inversion (direct current becomes interchange), brake unit, driver element, detecting unit microprocessing unit.Frequency converter close to the inner portion IGBT cut-off the voltage and the frequency that adjust out-put supply; there is provided the supply voltage required for it according to the actual needs of motor, so reach energy-conservation, the object of speed governing, in addition; frequency converter also has a lot of defencive functions, as overcurrent, overvoltage, overload protection etc.Along with improving constantly of industrial automatization, frequency converter have also been obtained application widely.Usual frequency converter is provided with openable shell; but it is more practical in order to make in the volume of frequency converter and profile; usually the opening handle of shell of frequency converter can be cancelled; arrange although it is so and can bring certain convenience; but in some specific situations; when namely needing often to open shell of frequency converter, do not have opening handle to seem and extremely bother, and traditional handle arranges the installation that can not utilize frequency converter.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of person easy to use and opens locking device on the frequency converter of shell of frequency converter.
For solving the problems of the technologies described above, described frequency converter comprises shell, described locking device is arranged at shell of frequency converter place, described locking device comprises lock piece and opening tool, described inner surface of outer cover and opening tool corresponding position are provided with lock piece, described opening tool and outer surface of outer cover are flexibly connected, and described lock piece is fixedly connected with inner surface of outer cover.
After have employed said structure, the setting of opening tool and lock piece can well be opened and locking this frequency converter, and opening tool overcomes technology prejudice in the past, have employed movable, like this when frequency converter opened by needs, opening tool is loaded, when not needed, opening tool also can be taken out, and both ensure that frequency converter does not increase relative volume, also facilitates people and opens this frequency converter or close.
As further improvement of the utility model, described opening tool is microscler handle, and described microscler handle is magnetic material, and described lock piece is shape and the size microscler gag lever post consistent with microscler handle, and described microscler gag lever post is can magnetic conductive metal material.
After have employed said structure, opening tool is microscler handle and for magnetic material, and lock piece is microscler gag lever post and for can magnetic conductive metal material, microscler gag lever post be fixed on inner surface of outer cover in addition, so, when needs are opened, only microscler handle need be loaded onto, because microscler gag lever post and microscler handle are that magnetic coordinates, when two parts magnetic are attracting, while rotating microscler handle, microscler gag lever post also and then rotates, and serves the spacing technique effect can taken again.
As further improvement of the utility model, microscler gag lever post corresponding position on described outer surface of outer cover and inner surface of outer cover is provided with gathering sill, described gathering sill comprises pilot hole and guide rail, and described microscler handle one end is provided with the lead suitable with this pilot hole.The corresponding pilot hole position, one end of described microscler gag lever post, be provided with a hinge hole, described inner surface of outer cover is provided with the jointed shaft suitable with this hinge hole.
After have employed said structure, the setting of gathering sill, microscler handle can be made well to be connected with microscler gag lever post, and microscler gag lever post carries out hinged, also well closes frequency converter.
Accompanying drawing explanation
figure 1 shows that the self-contained schematic diagram of shell;
figure 2 shows that microscler handle isolating construction schematic diagram;
figure 3 shows that frequency converter internal construction schematic diagram.
Detailed description of the invention
As shown in Figure 1, described frequency converter comprises shell (1), described locking device is arranged at shell of frequency converter place, described locking device comprises lock piece (4) and opening tool (3), described shell (1) inner surface and opening tool (3) corresponding position are provided with lock piece (4), described opening tool (3) and shell (1) external surface are flexibly connected, and described lock piece (4) is fixedly connected with shell (1) inner surface.The setting of opening tool (3) and lock piece (4) can well be opened and locking this frequency converter, and opening tool overcomes technology prejudice in the past, have employed movable, like this when frequency converter opened by needs, opening tool is loaded, when not needed, opening tool also can be taken out, both ensure that frequency converter did not increase relative volume, also facilitate people to open this frequency converter or close, and outer casing bottom is provided with stopping means and stopper slot, then further facilitate the connection between the shell of frequency converter and inner casing, serve good fixation.
As shown in Fig. 1 Fig. 2, described opening tool (3) is microscler handle (31), described microscler handle (31) is magnetic material, and described locking system (4) is shape and the size microscler gag lever post (41) consistent with microscler handle, and described microscler gag lever post (41) is can magnetic conductive metal material.Opening device (3) is for microscler handle and be magnetic material, locking system (4) is for microscler gag lever post (41) and be can magnetic conductive metal material, microscler gag lever post (41) is fixed on inner surface of outer cover in addition, so, when needs are opened, only microscler handle (31) need be loaded onto, because microscler gag lever post (41) and microscler handle (31) are magnetic cooperation, when two parts magnetic are attracting, while rotating microscler handle (31), microscler gag lever post (41) also and then rotates, and serves the spacing technique effect can taken again.
As shown in Fig. 2 Fig. 3, microscler gag lever post (41) corresponding position on described outer surface of outer cover and inner surface of outer cover is provided with gathering sill (7), described gathering sill (7) comprises pilot hole (71) and guide rail (72), and described microscler handle (31) one end is provided with the lead (311) suitable with this pilot hole (71).Corresponding pilot hole (71) position, one end of described microscler gag lever post (41), be provided with a hinge hole, described inner surface of outer cover is provided with the jointed shaft suitable with this hinge hole.The setting of gathering sill (7), microscler handle (31) can be made well to be connected with microscler gag lever post (41), and microscler gag lever post carries out hinged, also well closes frequency converter.
