Description
Technical field
The utility model belongs to locking device technical field, and in particular to a kind of self-locking type bolt.
Background technology
Usually used bolt at present, deviates from order to prevent, all can trepanning at one end, and fixed using Type B pin, although can
Type B pin first must be extracted and is inserted into when leaning on, but plugging bolt operation, and operation is relatively complicated.It is therefore desirable to design a kind of operation
Simplicity, being capable of fast insert-pull and the bolt with self-locking function.
Utility model content
(1) technical problems to be solved
The utility model proposes a kind of self-locking type bolts, to solve how to simplify operation, realization fast insert-pull and self-locking
Technical problem.
(2) technical solution
In order to solve the above-mentioned technical problem, the utility model proposes a kind of self-locking type bolt, which includes outer tube, core
Axis, ball, spring and hand handle；Wherein, outer tube have step structure, for mandrel outer tube travel forward into
Row limit；The front end of outer tube offers stepped hole, for being limited to the movement of ball；Mandrel is mounted in outer tube, mandrel
Middle part has bulge-structure, is limited at step structure for mandrel when travelling forward, and mandrel front end has narrower portion；Bullet
Spring is set in the back segment of mandrel, and power is provided for travelling forward for mandrel, and the front end of spring is abutted with bulge-structure, rear end with
The rear end of outer tube abuts；Hand handle is connected to the rear end of mandrel, and positioned at the outside of outer tube, for pulling mandrel to move backward；
Ball is embedded in stepped hole by outer tube, and is held out against in stepped hole by the thicker part of mandrel point so that ball is outside outer tube
Surface bulge, it is ensured that bolt will not be deviate from from pin hole, realize the self-locking of bolt；When mandrel moves backward under the pulling of hand handle
When, the narrower portion of mandrel front end moves at ball so that ball is retracted to from stepped hole within the outer surface of outer tube, it is ensured that
Bolt is deviate from from pin hole, realizes the unlock of bolt.
Further, the rear end of outer tube is equipped with draw ring.
Further, draw ring is welded on the rear end of outer tube.
Further, the shape of draw ring is triangle or circle.
Further, mandrel can rotate in outer tube.
Further, mandrel cannot rotate in outer tube.
Further, the thicker part of mandrel point has tapered intermediate portion between narrower portion.
Further, ball uses steel ball.
(3) advantageous effect
The utility model proposes self-locking type bolt, including outer tube, mandrel, ball, spring and hand handle utilize the fortune of mandrel
Dynamic and its diameter change holding out against in stepped hole or deviates to control, realizes self-locking and the solution of bolt to ball in outer tube
Lock.The self-locking type bolt can realize quick one-handed performance, easy to use, simple in structure, durable.
Description of the drawings
Fig. 1 is structural schematic diagram of the utility model embodiment self-locking type bolt in self-locking state；
Fig. 2 is structural schematic diagram of the utility model embodiment self-locking type bolt in unlocked state.
Specific implementation mode
To keep the purpose of this utility model, content and advantage clearer, with reference to the accompanying drawings and examples, to this practicality
Novel specific implementation mode is described in further detail.
The present embodiment proposes a kind of self-locking type bolt, as shown in Figure 1, the bolt includes mandrel 1, steel ball 2, outer tube 3, spring
4 and hand handle 5.Wherein, 3 inside of outer tube has step structure, for being limited in travelling forward for outer tube to mandrel 1.
The front end of outer tube 3 offers stepped hole, for being limited to the movement of steel ball 2.Mandrel 1 is mounted in outer tube 3, in mandrel 1
Portion has bulge-structure, is limited at step structure for mandrel 1 when travelling forward.Mandrel 1 being capable of the rotation in outer tube 3.
There is 1 front end of mandrel narrower portion, thicker part point to have tapered intermediate portion between narrower portion.Spring 4 is set in mandrel 1
Back segment, provide power for travelling forward for mandrel 1, the front end of spring 4 is abutted with bulge-structure, after rear end and outer tube 3
End abutment.Hand handle 5 is connected to the rear end of mandrel 1, and positioned at the outside of outer tube 3, for pulling mandrel 1 to move backward.Steel ball 2
Stepped hole is internally embedded by outer tube 3, and is held out against in stepped hole by the thicker part of mandrel 1 point so that steel ball 2 is outside outer tube 3
Surface bulge, it is ensured that bolt will not be deviate from from pin hole, realize self-locking.
When being moved backward under pulling of the mandrel 1 in hand handle 5, the narrower portion of 1 front end of mandrel moves at steel ball 2, makes
Steel ball 2 is retracted to from stepped hole in outer tube 3 and will not be completely out out of stepped hole, it is ensured that bolt is deviate from from pin hole, real
It now unlocks, as shown in Figure 2.When unclamping hand handle 5, spring 4 can push 1 return of mandrel so that steel ball 2 is secured in step again
In hole, self-locking is realized.
In addition, being also welded with triangle draw ring in the rear end of outer tube 3.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
