Abstract
The utility model relates to a round nut with a groove. The round nut with the groove comprises a round nut body. A threaded hole is axially arranged in the nut body. An operating groove is arranged on the nut body. The axial end part of the nut body is provided with an elastic locking sleeve which is coaxially arranged with the nut body. The elastic locking sleeve is arranged in the shape of a circular truncated cone with a hole. The free end of the elastic locking sleeve is a small end. The diameter of the small end of the elastic locking sleeve is smaller than the diameter of the threaded hole of the nut body. Two open slots which are symmetrically arranged along the central axis of the elastic locking sleeve are arranged in the side wall of the elastic locking sleeve. Compared with the prior art, the round nut with the groove has the advantages of high locking reliability, loosening prevention and vibration prevention.
Description
Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of grooved round nut.
Background technique
Round nut normal with round nut lock washer adapted, during assembling, with in the groove on tongue insertion axle in packing ring, and in the groove with the outer tongue embedding round nut of packing ring, nut namely is locked; The axial restraint of Chang Zuowei rolling bearing.
Traditional round nut only relies on stopper ring stop locking, and when being in the working environment of frequent vibration, bolt easily occurs loosening and comes off, and causes to connect unreliablely, during in particular for important events such as aircraft instruments, is easy to cause a serious accident.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of grooved round nut of reliable lock.
for achieving the above object, the utility model provides following technological scheme: a kind of grooved round nut, include circular nut body, offer on nut body tapped hole is set vertically, offer operating groove on nut body, it is characterized in that: described nut body axial end portion is provided with the elastic locking cover with the coaxial setting of nut body, the elastic locking cover is round platform setting with holes, the free end of elastic locking cover is small end, the small end aperture of elastic locking cover is less than nut body tapped hole aperture, offer two along symmetrically arranged two opening slots of lock sleeve central shaft on elastic locking cover sidewall.
The small end aperture of described elastic locking cover is 0.6 to 0.65 with the ratio in nut body tapped hole aperture.
Described nut body offers radially fluting with respect to the other end that elastic locking cover one end is set, and radially the degree of depth of fluting is 0.28 to 0.30 with the ratio of nut body thickness.
By adopting technique scheme, hold coupling shaft tightly by the elastic locking cover, realize the locking of round nut, make nut check reliable, the small end aperture setting of elastic locking cover makes round nut can reach reliable locking and is convenient to operation again, and radially fluting arranges convenient operation.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
Referring to accompanying drawing 1, the disclosed a kind of grooved round nut of the utility model includes circular nut body 1, offers on nut body 1 tapped hole 10 is set vertically, offers operating groove on nut body 1; Described nut body 1 axial end portion is provided with the elastic locking cover 2 with nut body 1 coaxial setting, elastic locking cover 2 is round platform setting with holes, the free end of elastic locking cover 2 is small end, the small end aperture of elastic locking cover 2 offers two along symmetrically arranged two opening slots 20 of lock sleeve 2 central shafts less than nut body 1 tapped hole 10 apertures on elastic locking cover 2 sidewalls; And the ratio in the small end aperture of elastic locking cover 2 and nut body 1 tapped hole 10 apertures is 0.6 to 0.65.
Described nut body 1 offers with respect to the other end that elastic locking cover 2 one ends are set and radially slots 11, and 11 the degree of depth of radially slotting is 0.28 to 0.30 with the ratio of nut body 1 thickness.Certainly as the feasible technological scheme of the utility model, operating groove also can be axially grooved for what arrange around the round nut sidewall, but radially fluting arranges convenient operation, and fluting arranges therefore the utility model operating groove preferentially adopts radially.
