Abstract
The utility model relates to a cylindrical spring pressing nail, composed of a pressing nail, a spring, a guide rod, etc. The spring is arranged in the middle of the guide rod. When used for pressing articles, the utility model can compensate pressing force which is reduced due to shrinkage of some reasons for the articles to be pressed, and has enough mechanical strength for pressing tightly when the pressing force rebounces, so that the utility model can prevent the spring from deforming.
Description
The utility model belongs to fastener areas, refers in particular to a kind of spring pressed stud that is used for high-power transformer coil compressing structure.
In transformer device structure, need to adopt fastening piece to adopt and compress coil, to guarantee the proper functioning of coil, at present, large-scale iron core adopts common structural types such as malleation nail, anti-pressure nail and oleo cushion formula spring pressed stud to compress coil, and preceding two kinds impacting force is big inadequately, and can not (shrink because of insulation is arranged) lastingly, and the latter's accuracy of manufacturing requires height, does not generally also adopt.
The purpose of this utility model is that proposition is a kind of simple and practical, and cost is low, is easy to quick installation, and the spring pressed stud that constant pressure is lasting can overcome above-mentioned shortcoming, to improve the security of operation index of transformer.
The purpose of the utility model was communicated with following scheme realization:
The utility model is by pressing nail, spring, guide rod etc. to form, pressing nail and fixed body is screw-thread fit, rotation presses nail that the pressure nail is moved up and down at fixed body, pressure has nailed on a location nut, press the nail lower end that the upper press cover of one shrinkage pool location is arranged, be equipped with helical spring in the middle of upper press cover and the guide rod, be connected a base with guide rod.
Accompanying drawing and drawing explanation:
1-presses nail; The 2-fixed block; The 3-setscrew nut;
The 4-upper press cover; The 5-helical spring; The 6-guide rod;
The 7-base; The 8-collets; 9-is pressed thing.
Below in conjunction with embodiment and accompanying drawing the utility model is done a detailed description:
The utility model utilizes the fixed block 2 on the transformer to be stressed fulcrum, pressing nail 1 is an adjustment screw rod, one screw is arranged on the fixed block, can will press nail 1 to be fixed on the fixed block 2 by setscrew nut 3, upper press cover 4 touches with pressing nail joint, helical spring 5 is in the middle of guide rod 6, by upper press cover 4, guide rod 6, base 7 positioning and guidings.When the utility model is implemented; the decrement of the height may command spring of guide rod 6; promptly upper press cover 4 contacts with guide rod 6 before spring 5 is forced into the limit, and the pressure nail of this moment becomes the rigidity nail, when being pressed object 9 (as transformer coil) to shrink; then rely on the elastic compression of spring; when being pressed thing the pressure bounce-back to occur, (when bearing the short-circuit force impact as transformer) then presses nail because of being subjected to the real impact force of sending out; press nail protection spring and make upper press cover 4 and guide rod 6 be closed into rigidity, in order to avoid impaired.
The guide rod that is also advantageous in that of the present utility model play the guiding role to spring, and spring is being subjected to Beat not during pressure presses nail both to stablize constant voltage, protects again self not impaired, more can protect and pressed The safety of thing. It is securing member a kind of simple in structure, easy to use and reliable.
