the utility model provides a lock nut with adhesive tape dispensing groove, including the nut body, this internal tooth that is provided with bolt screw-thread fit of nut be equipped with the adhesive tape dispensing groove in the internal tooth of nut body the packing has thread sealing agent in the adhesive tape dispensing groove.
For the above technical solution, the applicant has further optimization measures.
Optionally, the glue dispensing groove is a plurality of grooves formed along the inner wall of the inner tooth, and at least one end of each groove extends out of one end face of the nut body.
Furthermore, the groove is straight and is arranged along the axis direction of the inner teeth.
Optionally, the glue dispensing groove is a plurality of grooves obliquely arranged along the inner wall of the inner tooth, and at least one end of each groove extends out of one end face of the nut body.
Optionally, the inner teeth of the nut body are stepped holes, and the stepped surface on the side with the larger aperture forms the dispensing groove.
Furthermore, the inner wall of the glue dispensing groove is provided with a plurality of ribs for increasing the cross-sectional area.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
the utility model discloses a lock nut through special design's nut structure, sets up the glue dispensing slot that can fill thread sealing agent in the nut internal tooth, can improve the connection fastening nature between nut and bolt, so can play better loosening effect, dismantles also to be convenient for go on and can not lead to the fact the damage to nut and bolt when necessary, has guaranteed nut and bolt's life when having improved assembly efficiency.
