Abstract
The utility model discloses a furniture connecting nut anti-looseness structure which comprises a nut body with a screw hole. A circle of groove is formed in a position, adjacent to the upper end face of the nut body, of the screw hole. A notch communicated with the screw hole and the nut body is formed in the upper end face of the nut body. The bottom face of the notch is level with the bottom face of the groove. An anti-looseness gasket with an opening is arranged in the groove. The furniture connecting nut anti-looseness structure can prevent a nut from loosening after being fastened, is simple in structure, and good in anti-looseness performance.
Description
Technical field
The utility model relates to a kind of nut structure connected for furniture.
Background technique
Can cause nut loosening after general furniture has been used of a specified duration, and nut loosening can bring potential safety hazard.
The model utility content
Technical problem to be solved in the utility model just is to provide a kind of furniture attaching nut anti-loose structure, and simple in structure, anti-loosening performance is good.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of furniture attaching nut anti-loose structure, comprise the nut body that is provided with tapped hole, the adjacent nut body of described tapped hole upper-end surface is provided with a circle groove, described nut body upper-end surface is provided with a breach that is communicated with tapped hole and nut body outer side wall, described breach bottom surface is concordant with the bottom surface of groove, is provided with the lock washer of an opening in described groove.
As preferably, the circle structure that described lock washer is opening, lock washer is provided with the lug of extension in the opening both sides.
As preferably, described lock washer internal ring wall is provided with the burr of compacting.
As preferably, described lock washer is flexible steel ring.
The adjacent nut body of the tapped hole of the utility model nut upper-end surface is provided with a circle groove, be embedded with the lock washer of an opening in groove, and the nut body upper-end surface is provided with a breach that is communicated with tapped hole and nut body outer side wall, say that like this lock washer is nested in groove in advance, lock washer exposes breach at the lug of opening both sides, until nut after screw rod tightens and puts in place, the lug place is tightened, lock washer shrinks, lock ring is on screw flight, some is nested in groove simultaneously, thereby can prevent from becoming flexible after fastening nuts, simple in structure, anti-loosening performance is good.
