A kind of locking sword and sheath
Technical field
The present invention relates to daggers and swords technique with the apparatus field, especially a kind of locking sword and sheath.
Background technology
Although existing sword and scabbard can support the use, after sword is inserted scabbard, sword is easily arbitrarily extracted and is played by child in scabbard, there is potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is: the sword provide a kind of child arbitrarily to be extracted in scabbard by sword to play, eliminating safe hidden trouble and sheath.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of locking sword and sheath, be made up of sword and scabbard, and sword comprises sword body, pommel and handguard, main feature of the present invention is, the upper front of described scabbard near porch is provided with locking device.
The left side of described locking device is provided with lock core, is provided with supporting key in the lockhole of lock core, and the bottom of lock core is provided with deep gouge.
Front and the deep gouge corresponding position of described handguard are provided with cylinder plugs.
The end of described cylinder plugs is provided with tapered end.
Described lock core is provided with the dead bolt that tapered end can be pinned.
The upper right of described locking device is provided with manhole, and the top of manhole is provided with internal thread, and bottom is set to spherical through hole.
The top of described manhole be provided with screw-internal thread fit+head bolt.
The below of described+head bolt is provided with Compress Spring.
[below of described Compress Spring is provided with steel ball.
The diameter of described spherical through hole is less than the diameter of steel ball.
Described cylinder plugs is provided with the semi-circular recesses coordinated with steel ball near the top of handguard.
With screw-internal thread fit+Compress Spring and steel ball can be fixed in manhole by head bolt.
The bottom of manhole is set to spherical through hole, and the diameter of spherical through hole is less than the diameter of steel ball, can guarantee that steel ball is while coordinating with semi-circular recesses, can not deviate from from the bottom of manhole.
After sword body is extracted from scabbard, under the elastic force effect of Compress Spring, a part for steel ball gives prominence to manhole; When sword body inserts scabbard, the steel ball of outstanding manhole to slide in semi-circular recesses and sword body and scabbard is pinned.Like this, locking under the state opened, sword body also can not skid off in scabbard, and facilitates sword body insert scabbard or extracted in scabbard by sword body.
Because the left side of locking device is provided with lock core, the bottom of lock core is provided with deep gouge, the end of cylinder plugs is provided with tapered end, lock core is provided with the dead bolt that tapered end can be pinned, tapered end is inserted deep gouge, namely pinned by dead bolt, sword body cannot be extracted in scabbard, only has after opening lock by supporting key and just can extract sword body.Like this, just can prevent child from arbitrarily being extracted in scabbard by sword and play, thus eliminate safe hidden trouble.
