Description
Technical field
The utility model relates to a kind of hold down gag, particularly a kind of hold down gag that can be used in high voltage transformer.
Background technology
Along with the development of power technology, the capacity of transformer is increasing, and electric pressure is also more and more higher, and the effect of high voltage transformer in electric power system is aobvious outstanding in advance.Therefore the safe operation of high voltage transformer concerns the overall situation of electronic system.And the safe operation of high voltage transformer is subject to the impact of several factors, wherein against short-circuit performance is wherein important one.And the safe operation of high voltage transformer is subject to the impact of several factors, wherein against short-circuit performance is wherein important one.Because transformer device structure is in the past unreasonable, winding easily loosens, and coil easily gets loose, and causes the against short-circuit of transformer poor, have impact on the normal operation of whole electronic system.
Utility model content
The utility model object provides one to be installed in high voltage transformer to overcome the deficiencies in the prior art, for playing the hold down gag of compression and the effect of compacting winding.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hold down gag, comprises fixed mount, thread bush, screw rod, locking nut, slide block, fixed block, sliding sleeve, elastomeric element and handle; Thread bush is provided with in described fixed mount; Described screw rod is through thread bush; On described screw rod, cover has locking nut; Described locking nut is positioned at below thread bush; The bottom of described screw rod is provided with slide block; Described slide block slides in sliding sleeve; Described sliding sleeve is fixed in fixed block; Elastomeric element is provided with between the bottom of described slide block and the inner bottom surface of sliding sleeve; The top of described screw rod is provided with handle.
Preferably, the top of described sliding sleeve is provided with the spacing ring that anti-limited slip block is deviate from.
Preferably, described elastomeric element is spring.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Hold down gag of the present utility model, can to the object continu to press below fixed block, when being applied in high voltage transformer, be installed on below upper yoke, contact with top board, can to top board continu to press, one is ensure that whole winding does not loosen between upper yoke and lower yoke, two is ensure that coil does not get loose between top board and lower platen, improve the against short-circuit ability of high voltage transformer, ensure the normal operation of high voltage transformer, effectively can ensure the quality of high voltage transformer.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of hold down gag of the present utility model;
Accompanying drawing 2 is the using state structural representation of hold down gag of the present utility model;

Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of hold down gag as shown in Figure 1, comprises fixed mount 1, thread bush 2, screw rod 3, locking nut 4, slide block 5, fixed block 6, sliding sleeve 7, elastomeric element and handle 8; Thread bush 2 is provided with in described fixed mount 1; Described screw rod 3 is through thread bush 2; On described screw rod 3, cover has locking nut 4; Described locking nut 4 is positioned at below thread bush 2; The bottom of described screw rod 3 is provided with slide block 5; Described slide block 5 slides in sliding sleeve 7; Described sliding sleeve 7 is fixed in fixed block 6; Elastomeric element is provided with between the bottom of described slide block 5 and the inner bottom surface of sliding sleeve 7; Described elastomeric element is for being preferably spring 9; The top of described sliding sleeve 7 is provided with the spacing ring 10 that anti-limited slip block 5 is deviate from; The top of described screw rod 3 is provided with handle 8.
A kind of hold down gag described in the utility model, swing handle, screw rod is descending, the below of fixed block and the object contact needing to extrude, and slide block slides in sliding sleeve, extrusion spring, until after spring is compacted, screws locking nut, prevent screw bolt loosening; Hold down gag is by the object continu to press of spring to needs extruding.
As described in the utility model a kind of hold down gag that accompanying drawing 2 shows, be applied in high voltage transformer, during installation, first iron core 11 is arranged on lower yoke 12, put winding 13, at installation upper yoke 14, fixed mount 4 is fixed with the upper yoke 14 of high voltage transformer, and fixed block 6 contacts with the top board 15 of winding 13.Hold down gag can to top board continu to press, one is ensure that whole winding does not loosen between upper yoke and lower yoke, two is ensure that coil does not get loose between top board and lower platen, improve the against short-circuit ability of high voltage transformer, ensure the normal operation of high voltage transformer, effectively can ensure the quality of high voltage transformer.
As shown in Figure 3, when being applied in high voltage transformer, described hold down gag has multiple around iron core circular symmetric array, ensure that the uniformity of pressure, the complete compacted reality of coil can be ensured, best, when described hold down gag is provided with 8, compress best results.
Below be only embody rule example of the present utility model, protection range of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
