Abstract
An elastic anti-loose self-locking hinged bolt trimmer comprises a hinged bolt, an axle sleeve bolt, springs, balls and an annular plug, wherein each spring is disposed in a counter bore on the edge of the large round hole of the hinged bolt, a ball bearing is arranged at the external end of the spring, the cylinder body of one end of the axle sleeve bolt penetrates the large round hole of the hinged bolt, the ball is snapped in a circular pit on the periphery of the axle sleeve bolt flange surface, the annular plug is rotationally mounted on threads of the top portion of the axle sleeve bolt cylinder body, the hinged bolt can be fixed by properly tightening after being clamped. The trimmer can be rotationally mounted on an indication rod to connect a turn-out track indication rod in using, when adjusting the hinged bolt, spring pressure on a flange can be overcame by rotating the axle sleeve bolt, the axle sleeve bolt is led to rotate in the round hole of the hinged bolt and then drives the hinged bolt to move on the indication rod. After a switch indicating position is adjusted properly, the axle sleeve bolt can be kept steady in the round hole of the hinged bolt without exerting any external force, thereby effectively preventing axle sleeve bolt from loosing, and guaranteeing reliable and safe usage of equipment.
Description
Technical field:
The locking self-locking type eyelet bolt of elasticity micro-adjuster parts, the connection adjustment that is suitable for railway switch switch representing bar is especially used, and belongs to metal rod and connects the adjustment technology field.
Background technology:
At present, on railway switch switch slide indication rod, be used for connecting the adjustment of switch indication breach eyelet bolt, normally to become flexible the clamp nut at eyelet bolt two ends, after making indication notch reach requirement by mobile eyelet bolt, again that nut is fastening, bother very much during adjustment, be difficult for adjusting to the right place, it is loosening easily to be used for two nuts of fastening eyelet bolt, according to this situation, in No. 97215190.7 " clearance adjustable type eyelet bolt " utility model of Chinese patent to the problems referred to above, terms of settlement has been proposed, adopt adjustment nut and the eyelet bolt regulatable structure that is integrated, greatly facilitate adjustment, but this structure is to adjusting the axle sleeve screw retention weak effect of usefulness, therefore carry out locking with the locking mode that between eyelet bolt and axle sleeve bolt, penetrates spring cotter that changes into of spiral nail the eyelet bolt two ends again, though can play locking effect, but because the gap of pin-and-hole is still spacious to some extent moving between eyelet bolt and axle sleeve bolt, especially after the indication notch adjustment is intact, eyelet bolt aligns with the pin-and-hole difficulty between the axle sleeve bolt, spring cotter can not very successfully penetrate pin-and-hole, brings many inconvenience on site maintenance work.
Summary of the invention:
The utility model provides the locking self-locking type eyelet bolt of a kind of elasticity micro-adjuster, do not need the external world manually to carry out locking operation, elastic pressure by spring between eyelet bolt and the axle sleeve bolt tightly props up mutually to the application force of ball, just can reach locking requirement by actv., the adjusting work program is simpler, convenient, fast.
The utility model is by eyelet bolt, the axle sleeve bolt, spring, ball, the annular plug constitutes, spring is placed in respectively in two counterbores at eyelet bolt big hole edge, a ball is put in the outer end of spring, the cylinder of axle sleeve bolt penetrates in the big hole of eyelet bolt, flange snaps in the annular concave panel of eyelet bolt one end, round concave shape nest on the flange and one side of something of ball block mutually, annular plug spinning is on the screw thread of axle sleeve bolt circle cylindrical shell end, block mutually with the annular concave panel of the flange other end, eyelet bolt is clamped suitably tight fully back to be fixed, during use, with the locking self-locking type eyelet bolt of elasticity micro-adjuster spinning on the thread rod of indication rod, by connecting iron it is connected with the switch representing bar, rotate the axle sleeve bolt of the locking self-locking type eyelet bolt of elasticity micro-adjuster as requested, the axle sleeve bolt overcomes spring and props up ball flange face periphery round concave shape nest applied pressure is rotated in the circular hole of eyelet bolt, driving eyelet bolt moves axially on the thread rod of indication rod, after the adjustment of switch indication position is suitable, tightly prop up the interior ball of axle sleeve bolt flange face round concave shape nest by the spring in the eyelet bolt, as not applying external force axle sleeve bolt is impossible come back rotation, but therefore actv. prevents the axle sleeve bolt looseness.
The big hole both ends of the surface that described eyelet bolt lower end connects are the ring concave face, and the concave panel of an end is provided with two circular counter bore of symmetry.
The cylinder internal diameter of described axle sleeve bolt one end is provided with the screw thread identical with the fluted nut of the other end, and the end of cylinder external diameter is provided with screw thread, and middle flange periphery is provided with 20 uniform round concave shape nests by cylinder.
Advantage of the present utility model: do not need the extraneous job procedure that manually carries out locking operation, tightly prop up mutually by elastic pressure between eyelet bolt and the axle sleeve bolt, can reach locking requirement by actv., and between eyelet bolt and axle sleeve bolt, also move without any spacious, make the adjustment maintenance work simpler, convenient, fast, alleviate working strength of workers, improved work efficiency.
