Embodiment Construction

[0009] The specific implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings. The first embodiment of the present invention provides a lock nut anti-loosening device, including a base 1, a threaded rod 5, and a lock nut 4. It is characterized in that it also includes Lock ring 2 and fuse 3. Internal threads are processed on the base body 1, and key grooves 101 are processed on the ends thereof. A key 201 is processed on the lock ring 2 to match with the key groove 101 on the base 1 . Align the center hole on the lock ring 2 with the center line of the internal thread on the base 1 , and insert the key 201 on the lock ring 2 into the key groove 101 on the base 1 . Screw the lock nut 4 onto the external thread of the threaded rod 5 . Screw the threaded rod 5 into the internal thread on the base body 1 after passing through the central hole on the lock ring 2 . Rotate the threaded rod 5 to make it reach a s...

Abstract

The invention discloses a locknut looseness preventing device which comprises a base body (1), a threaded rod (5) and a locknut (4) and further comprises a lock ring (2) and a safety wire (3). The lock ring (2) comprises a key (201). The connecting end of the base body (1) is provided with a key groove (101) matched with the key (201). The lock ring (2) further comprises a safety hole (202). The locknut (4) further comprises a safety hole (401). When the locknut looseness preventing device is used, the two safety holes are connected through the safety wire (3), the key (201) is matched with the key groove (101), and thus looseness prevention of the whole locknut looseness preventing device is achieved.

Description

technical field [0001] The invention belongs to mechanical design technology, and relates to a locking nut anti-loosening device. Background technique [0002] The threaded rod screwed into the base body needs to use a lock nut to prevent the threaded rod from loosening, and the lock nut itself is usually prevented from loosening by means of double nuts or lock washers. Double nuts require a lot of space, which cannot be implemented in applications where space is tight; lock washers are folded, which requires a high level of craftsmanship, and the anti-loosening is not reliable, and the failure rate is high. In addition: in the patent No. CN97240716.2, the application date is April 21, 1997, and the patent name is "automobile rear wheel hub lock nut stop lock plate" discloses a kind of automobile rear wheel hub lock nut stopper The lock piece device is composed of a stop lock piece, a lock nut and an adjustment nut lock washer, and realizes the function of locking the lock ...
