Description
Technical field
This utility model relates to a kind of locking mechanism, it is possible to achieve install effective locking of screw.
Background technology
For ensureing the reliability that screw is installed, under the environment such as vibration, realize effectively work, generally, be provided with
Screw lock structure.The most conventional locking mechanism is realized by lock washer, and lock washer is also known as lock washer or stop pad
Circle, belongs to a kind of securing member, is generally placed between nut and connected part.When screw element is by External Force Acting, its
Can be good at preventing loosening of screw element.In the locking mechanism of traditional screw thread class securing member, it is also possible to use self-locking
Nut, spring lock washer, duckbill lock washer or beat the form of electric fuse.But but in some particular job occasion, as
Part space structure is compact cannot arrange that traditional lock washer or lock washer are difficult to assembling and locking, causes securing member to loosen
Or even come off, easily cause damage of product.
Summary of the invention
The purpose of this utility model is to provide a kind of locking mechanism, can cannot arrange traditional locking space structure is compact
In the environment of packing ring or lock washer are difficult to assembling and locking, it is achieved the effective locking to screw, to meet product or mechanism
Locking requirement.
Concrete technical scheme of the present utility model is, described locking mechanism includes installing screw, lock washer, described
Installing and be provided with flat recess on screw, lock washer is arranged on installation screw and installs between matrix, outside described lock washer
Path portion upwardly extends and is coated on outside screw, and the other end is provided with downward boss and joins with installing the groove arranged on matrix
Close.Described lock washer material is metal, and the wall thickness upwardly extending part of lock washer is 0.4～0.5mm.
Lock washer in use, is first arranged between matrix and screw during assembling by this utility model, lock washer
Then the groove of boss insertion matrix is screwed into slotted head screw, after the installation completing screw, by the extension of lock washer
Symmetrical punching is locked in the flat recess of screw head, is finally completed whole assembling and the locking of lock washer.
This utility model provides a kind of new-type locking mechanism, has simple in construction, is easily worked, assembles and lock technique
The advantage that simple to operation, locking mode is safe and reliable, and less than the space needed for the assembling of traditional lock washer and locking, energy
Enough meet assembling and the locking requirement of threaded securing member under special occasions.
