Description
Technical field
The present invention relates to transformer mounting technique field more particularly to a kind of EE type transformers for facilitating installing and dismounting.
Background technique
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, with the difference of concrete function, is become
Depressor is divided into more classification, such as switching voltage device, power transformer etc..
Currently, traditional transformer mainly includes magnetic core, the coil being looped around on magnetic core and is wrapped in outer outside coil
Shell, in use, by the way that spiral shell can be passed through in the welding of the edge of shell or integrally formed with multiple ear blocks to extend out
Ear block is mounted on the predetermined position of circuit board or equipment by bolt or screw, then connects the route on transformer again.
But during actual installation transformer, often according to practical situation, the ear block of transformer is arranged
At being in preset tilt angle with case surface, so that ear block can obviously be compared with the mounting surface on abutted equipment, this mode
Trouble, influences the installation effectiveness of transformer, and be unfavorable for the batch production of transformer, meanwhile, ear block extends case surface,
Very occupied space will definitely increase certain cost.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of EE type transformation for facilitating installing and dismounting
Device, can very easily realize the Fast Installation of transformer, while can also save space, reduce unnecessary cost.
Above-mentioned purpose of the invention has the technical scheme that
A kind of EE type transformer facilitating installing and dismounting, comprising: the shell outside coil；It is provided on the outer wall of shell two sides
The consistent strip groove of multiple extending directions；Extending direction slidingtype along strip groove is connected to the movable block in strip groove；With
Mounting blocks that movable block is hinged, offering mounting hole；For driving movable block along strip groove extension side in strip groove
To the elastic component of sliding；For limiting movable block and mounting blocks, so that mounting blocks are placed in strip groove on shell
Limiting device.
By adopting the above technical scheme, by the way that strip groove, the hinged mounting blocks on movable block is arranged, mounting blocks can rotate appearance
It sets in strip groove, by limiting device, movable block and mounting blocks can be limited in the pre-position of strip groove, made
The space for obtaining transformer can be saved, to save unnecessary cost；When needing to install transformer, limit can be released
Limitation of the position device to movable block, allows mounting blocks any rotation angle according to the actual situation, so that mounting blocks
Be adapted to different installation sites, allow staff very easily by screw or bolt by transformer be fixed on equipment or
On the predetermined position of circuit board, by this scheme, the difficulty of transformer installation and adjustment can be reduced, so that transformer is being installed
When enhanced convenience.
The present invention is further arranged: the limiting device include: be mounted in hull outside for limit movable block, with
Movable block is limited in the first limit assembly of strip groove upper section；Movable block is limited in the second limit group of strip groove bottom end
Part；And mounting blocks are limited in the third limit assembly in strip groove.
By adopting the above technical scheme, movable block can be limited in strip groove by the first limit assembly of setting, reduced and moved
The case where motion block slides, and mounting blocks can be limited in strip groove by the second limit assembly, so as to save transformation
The space of device then can be when mounting blocks and equipment be installed by the third limit assembly of setting, and movable block can be limited in
In strip groove, the stability of transformer installation is further increased.
The present invention is further arranged: first limit assembly includes: the item for being provided with and being connected on shell with strip groove
Shape port；Activity is interspersed in the gag lever post that in bar shaped port and end is threadedly coupled with movable block；And it is assemblied in gag lever post
Locking piece far from movable block one end.
By adopting the above technical scheme, movable block when moving, can drive gag lever post to slide along bar shaped port, work as movement
When the predetermined position that block is moved to strip groove needs fixed, can with rotation locking elements, so that locking piece is inconsistent with housing exterior walls,
To limit movable block, freely limiting for movable block can be very easily realized through this structure.
The present invention is further arranged: first limit assembly includes: the limiting slot for being provided with strip groove inner wall；Activity

Stablize.
Meanwhile locating rod 7 is fixed in the bottom interior wall of strip groove 10, and offered on the bottom face of movable block 12
Locating slot 71, when on the bottom predetermined position that movable block 12 is in strip groove 10, locating rod 7 can mutually go embedding with locating slot 71
It closes, the contact area between movable block 12 and locating rod 7 can be increased, further increase the stability of movable block 12, to subtract
The case where few movable block 12 loosens.
It is inlaid with ball 8 close to the side of 10 inner wall of strip groove in movable block 12, in movable block 12 along in strip groove 10
When wall slides, the ball 8 of setting can be in contact with the inner wall of strip groove 10, and ball 8 can reduce movable block 12 and strip groove 10
Frictional force between inner wall, so that the sliding of movable block 12 is more smooth.
In addition, being also bonded elasticity layer 6, in the present embodiment, elastic layer 6 by glue on the bottom face of mounting blocks 2
Can be flexible rubber layer, after mounting blocks 2 and circuit board or equipment are mutually fixed, rubber layer can very closely with electricity
The surface of road plate fits, and can then increase the stiction between circuit board, pine occurs so as to reduce mounting blocks 2
Dynamic situation, meanwhile, rubber layer can also play a certain protective role circuit board, mitigate mounting blocks 2 and cause to circuit board
Crush injury.
Embodiment 2: as shown in figure 3, difference from example 1 is that the difference of the first limit assembly, in this implementation
In example, the first limit assembly includes: the limiting slot 32 for being provided with 10 inner wall of strip groove；Activity is accommodated in the limit in limiting slot 32
Block 33；And be mounted on the driving spring 34 in limiting slot 32 for driving limited block 33 mobile, one end of driving spring 34 with
The inner wall of limiting slot 32 is mutually fixed, the other end is fixed with 33 phase of limited block, and opens in movable block 12 close to the side of limited block 33
Equipped with the limit hole to match with limited block 33；In addition, being also equipped with the shifting block for stirring limited block 33 on 1 outer wall of shell
35, shifting block 35 can drive limited block 33 far from limit hole, and the bar shaped passed through for shifting block 35 is offered on the outer wall of shell 1
Sliding mouth.
When movable block 12 is moved to scheduled position, the driving spring 34 of setting can utilize the elastic force of itself, automatically
Driving limited block 33 along limiting slot 32 inner wall slide so that limited block 33 be inserted into limit hole in, so that movable block 12 be limited
System is on the predetermined position of strip groove 10；When needing to release the limitation to movable block 12, shifting block 35 is stirred, it is made to drive limit
Block 33 slides, at this point, driving spring 34 can be compressed, so that limited block 33 is extracted out out of limit hole, releases to shifting
The limitation of motion block 12.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification made to the present embodiment and do not create contribution after reading this specification, but as long as in this hair
All by the protection of Patent Law in bright scope of the claims.
