Abstract
The utility model discloses a one-way nut, relating to a fastener for the industry. The utility model is characterized in that a. The one-way nut comprises a nut sleeve (1), a nut core (2) which is provided with thread, a closing cap (3), a spring (4) and a bead (5); b. The external edge of the nut core (2) is provided with a rabbet (7) and a circle of grooves (8); c. The nut sleeve 1 is sheathed on the nut core (2); d. The nut sleeve (1) is drilled with a pore (6), and the bead (5) and the spring (4) are sealed in the pore (6) by the closing cap (3). The one-way nut has the advantages of fastening use and no looseness use, so the one-way nut can be in particular used as the fastener which can prevent other people from demounting.
Description
The utility model relates to fastening piece.
As everyone knows, as fastening piece with the matching used nut of screw on screw if be to tighten towards the rotation of direction, opposite spin is to back-out so, vice versa.
If above-mentioned nut is mixed screw as a kind of fastening piece that can prevent that other people from dismantling---as when being used to install iron gate-steel sash, people take earlier nut to be tightened and then with welding machine with nut and screw weldering extremely or with instrument the screw thread on the screw is beaten colored way and prevent nut loosening usually.This shows that this way is very inconvenient.
The purpose of this invention is to provide and a kind ofly can only unidirectional rotation promptly can only tighten the nut that to back-out.To satisfy the needs of people under above-mentioned these special occasions.
The structural representation of given with reference to the accompanying drawings One-way nut is described concrete structure of the present utility model below.
This One-way nut provided by the utility model has following feature:
A. it is made of swivel nut 1, screwed spiral shell core 2, capping 3, spring 4 and pearl 5;
B., seam 7 is arranged on the outer of spiral shell core 2 and also have a circle groove 8;
C. swivel nut 1 is enclosed within on the spiral shell core 2;
D. be drilled with hole 6 on the swivel nut 1, pearl 5 and spring 4 be enclosed in the hole 6 by capping 3.
As seen from the figure, no matter how the spiral shell core swings it can not split away off this from swivel nut be that another partly then is stuck in the groove 8 of spiral shell core 2 in the hole 6 of swivel nut 1 because the some of pearl 5 has been stuck in, and it has played the effect of location.When swivel nut rotated as if clockwise direction, pearl 5 can only slide in the groove 8 at spiral shell core 2 under the drive of swivel nut 1 and can not drive 2 rotations of spiral shell core.If swivel nut 8 is inverse time can the direction rotation time, thereby pearl 5 will be stuck in and drives spiral shell core 2 on the seam 7 of spiral shell core 2 and be rotated.
The utility model brings convenience for the people that are engaged in installation or fitting-out work.
