Abstract
The utility model relates to a dry type disc spring and pressing stud structure. The disc spring and pressing stud structure comprises a cushion block arranged at the upper ends of coils, and pressing studs arranged on a clamp, and is characterized in that grooves are formed in the cushion block; a string of disc springs, and a cylindrical cushion plate penetrating through each string of disc springs are arranged in each groove; the upper end part of each cylindrical cushion plate is provided with a cover plate used for limiting the position of each string of disc springs; and the lower ends of the pressing studs press against the cover plates. By the dry type disc spring and pressing stud structure, the compression degree of the pressing studs can be adjusted by using the deformation of the strings of disc springs, and a problem that the pressing studs, which are tightly pressed when assembled, are loosened after the pressing studs are lifted several times can be fully and effectively solved.
Description
Technical field
The utility model relates to a kind of dry type dish spring and presses pin structure, is specially adapted to large-scale dry-type transformer.
Background technology
The device body compressing structure of dry-type transformer generally adopts the combination hold down gag of pressing nail, cushion block, rubber blanket; Size adjustment is confirmed through the strain of rubber blanket; And will with the respective outer side edges of iron core folder, this structure has obtained sufficient application and has played good effect on small-sized distribution transformer.But this combination hold down gag is used on the large product of dry type certain limitation has just been arranged; At first large product is bulky; The dimensional discrepancy of component structural is also bigger; Corresponding iron core folder structure is also different, only leans on the strain of rubber blanket can not guarantee that coil compresses, and presses nail to compress in the time of can occurring assembling and through lifting back several times pressing the loosening phenomenon of nail; This phenomenon can be improved through reducing folder screw hole dimensions deviation, but also can't obtain fully effectively solving.
Summary of the invention
In view of the deficiency of prior art, the purpose of the utility model is to provide a kind of can the solution fully effectively to press the dry type dish spring of the easily loosening problem of nail to press pin structure.
To achieve these goals; The technical scheme of the utility model is: a kind of dry type dish spring is pressed pin structure; Comprise the cushion block that is arranged at coil upper end and the pressure nail that is arranged on the folder, offer groove on the said cushion block, be provided with a string disk spring in the said groove and through the cylindrical backing plate of this string disk spring; The upper end of said cylindrical backing plate has a cover plate that limits this string disk spring position, and the lower end of said pressure nail props up this cover plate.
Preferably, said a string disk spring is made up of some disk springs to make-up.
Preferably, said a string disk spring is made up of some disk spring and disk springs that fasten bottom portion of groove to make-up.
Preferably, the lower end of said pressure nail is connected with cover plate.
Preferably, said cushion block is wedge shape.
Compared with prior art; The utlity model has following advantage: this dry type dish spring presses pin structure to regulate the compressing degree of pressing nail through the deformation stroke of a string disk spring, can solve fully effectively to press to bind that timing compresses and problem through becoming flexible after lifting by crane several times.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the enlarged diagram at A place among Fig. 1.
Among the figure: 1-presses nail, 2-jam nut, 3,8,9, the 11-rubber slab, 4, the 10-correcting wedge, 5-high-tension coil, 6-epoxy glass fabric tube, 7-low-voltage coil, 12-disk spring, the cylindrical backing plate of 13-, 14-cover plate, 15-groove, 16-folder, 17-iron core.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
With reference to figure 1 ~ 2; A kind of dry type dish spring is pressed pin structure; Comprise correcting wedge 4 that is arranged at coil upper end and the pressure nail 1 that is arranged on the folder 16; It is characterized in that: offer groove 15 on the said correcting wedge 4, be provided with a string disk spring 12 in the said groove 15 and through the cylindrical backing plate 13 of this string disk spring 12, the upper end of said cylindrical backing plate 13 has a cover plate 14 that limits these string disk spring 12 positions; The lower end of said pressure nail 1 props up this cover plate 14, and the lower end of this pressure nail 1 can directly be connected with cover plate 14 certainly.
In order to enlarge the deformation stroke of this string disk spring 12; Said a string disk spring 12 is made up of some disk spring 12 and disk springs 12 that fasten groove 15 bottoms to make-up; But be not limited to this, this string disk spring 12 can also be only to be made up of some disk springs 12 to make-up certainly.
The operation principle of the utility model is following: press nail 1 cover plate 14 through cylindrical backing plate 13 upper ends that power is delivered to disk spring 12; Regulate the compressing degree of pressing nail 1 by the deformation stroke of disk spring 12; How many sheet numbers of disk spring 12 determines the size of deformation stroke; Fully offset the dimensional discrepancy of folder 16 screws, guaranteed that coil can be fully compacted.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
