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
The invention belongs to mechanical designing technique, relate to a kind of locking nut locking device.
Background technology
The threaded rod being screwed into matrix needs to prevent threaded rod from getting loose with locking nut, locking nut itself locking, and the mode usually by double nut or lock washer realizes. Double nut needs more space, cannot implement in the application examples that space is nervous; Lock washer adopts the mode of turnover, requires higher and locking not firm to technological level, and crash rate is higher. Additionally: be CN97240716.2 in the patent No., date of application is on April 21st, 1997, patent name is a kind of locking washer for locking nut of car rear wheel hub device disclosed in the patent of " locking washer for locking nut of car rear wheel hub ", it is made up of stop locking plate, locking nut and adjusting nut lock washer, it is achieved by the function in locking nut lock jail. It is locking that technical scheme used by this patent adopts the mode of turnover stop locking plate to realize locking nut, requires higher and locking not firm to technological level.
Summary of the invention
The technical problem to be solved in the present invention is in that, it is proposed to a kind of locking nut locking device, and solving locking nut in prior art needs more space, requires higher and locking not firm to technological level, the problem that crash rate is higher.
A kind of locking nut locking device is provided for solving the problems referred to above technical solution of the present invention, including matrix, threaded rod, locking nut, also include lock ring and electric fuse, the link including matrix described in key on described lock ring has the keyway agreed with described key, described lock ring also includes also including on locking nut described in insurance hole insurance hole, described threaded rod there is external screw thread, female thread is had in described matrix, described electric fuse one end is connected with the insurance hole on described lock ring, the other end is connected with the insurance hole on described locking nut, described threaded rod is threaded connection the centre bore through described locking nut the described lock ring of traverse, described lock ring is connected by described key and described keyway with matrix, described threaded rod and described matrix are threaded connection.
The locking nut locking device that technical solution of the present invention provides by key between lock ring with matrix and keyway coordinate and to realize locking nut by the connection of electric fuse between lock ring and nut locking, implement simply, and energy repeated disassembled and assembled.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, specific embodiments of the present invention are further described in detail, wherein:
Fig. 1 is the combinative structure schematic diagram of the present invention
Fig. 2 is the fractionation structural representation of the present invention
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention being described in further details, first embodiment of the invention provides a kind of locking nut locking device, including matrix 1, threaded rod 5, locking nut 4, it is characterised in that also include lock ring 2 and electric fuse 3. On matrix 1, processing has female thread, and on its termination, processing has keyway 101. On lock ring 2, processing has key 201, matches with the keyway 101 on matrix 1. Centre bore on lock ring 2 is alignd with the female thread centrage on matrix 1, the key 201 on lock ring 2 is inserted in the keyway 101 on matrix 1. Locking nut 4 is screwed on the external screw thread of threaded rod 5. Threaded rod 5 is screwed in the female thread on matrix 1 after the centre bore on lock ring 2. Rotating threaded rod 5 makes it arrive suitable position, and rotation lock nut 4 makes it move towards the direction near matrix 1, and the face relative with lock ring 2 until locking nut 4 is close to. By electric fuse 3 through the insurance hole 202 on lock ring 2, after twisting into twisted shape, it is then passed through the insurance hole 401 on locking nut 4, then electric fuse 3 end is twisted into twisted shape accomplishes fluently insurance. Noting, the tension direction of electric fuse 3 should be identical with the direction of rotation that locking nut 4 moves near matrix 1.
