The present invention for the above-mentioned prior art the problem of, propose a kind of forced locking device, it is simple in structure, can
It realizes auto lock, high rigidity and high intensity locking and dismounts quick and convenient.
A kind of forced locking device, including the first noumenon and the second ontology, second ontology is cylindrical and its circumferential direction
Equipped with an annular groove；The first noumenon is evenly arranged with several bayonets, several bayonets in central column and its circumferential direction
It is respectively arranged with a locking unit；When second ontology stretches into the first noumenon intracavitary, several locking unit difference
It is connected on the annular groove by several bayonets, is connected to make the first noumenon and second ontology fix
It connects.
Preferably, the locking unit includes shell, the shell is fixed on the first noumenon, and on the shell
Be coaxially disposed limit hole, threaded hole, pilot hole and card hole, the limit hole, threaded hole, pilot hole, card hole and the bayonet according to
It is secondary to be connected, it is equipped with a steel ball in the card hole, a compressed spring is equipped in the pilot hole, a lock is equipped in the threaded hole
Determine bolt, one end of the compressed spring is connect with the steel ball, the other end and the pilot hole and the threaded hole junction
End face connection, the spring is to provide the elastic force that the steel ball is caught on the annular groove, and the limit hole is to logical
It crosses screwing tool and screws the locking bolt so that the locking bolt is connected on the steel ball, to lock described first
The connection of ontology and second ontology.
Preferably, the annular groove is V-groove.
Preferably, the shell is bolted on the first noumenon and the bolt is arranged in counterbore.
Preferably, the internal diameter of the limit hole is less than the head outer diameter of the locking bolt, to prevent the locking spiral shell
Bolt deviates from the shell.
Preferably, the axial direction of second outer body is equipped with a guide groove, in the axial direction on the inside of the first noumenon
Equipped with the feather key compatible with the guide groove.
Preferably, the guide groove is V-groove, the cross section of the feather key is triangle.
Preferably, the front end that the front end of the first noumenon sets orifice chamfer and second ontology also is provided with cylinder and falls
Angle.
Compared to the prior art, the present invention has the following advantages：
(1) forced locking device of the invention only can be real by the first noumenon and the second ontology by several locking units
Now connect, it is simple in structure, easy to use；
(2) forced locking device provided by the invention, under the action of compressed spring, the steel ball in locking unit can be automatic
The annular groove being caught in the second ontology realizes the auto lock between the first noumenon and the second ontology；
(3) forced locking device of the invention screws locking bolt and steel ball is pressed on the second ontology after auto lock
Annular groove in, realize several locking units active locking, realize high rigidity and high intensity locking；
(4) no matter when depositing power or moment loading in which directions between the first noumenon and the second ontology, pass through steel
The power that ball is applied in locking bolt is always axle power, not will produce moment of flexure in locking bolt and leads to locking bolt
Flexural deformation, external force do not interfere with the normal dismounting of locking bolt always, i.e. this forced locking device can under external force just
Often dismounting；
(5) forced locking device of the invention is only fixed by several lock cells, by screwing several locking bolts i.e.
The separation and connection of the first noumenon and the second ontology can be achieved, dismounting is quick and convenient.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
