Problem encountered at present.
Invention content
The technical problem to be solved by the utility model is to provide a kind of self locking expansion bars, pass through the protrusion energy of scotch
The self-locking in location hole can not restPose, and continue to direction of extension move can automatic unlocking, can be contracted after unlock
Return original length.
Technical solution is used by the utility model solves its technical problem：A kind of self locking expansion bar is provided, including
Outer tube, inner tube and sliding block, the outer middle side part of the outer tube are equipped with location hole, and internal slide is socketed with inner tube, described
The side of inner tube is slidably fitted with sliding block, and scotch is rotatablely equipped on the downside of the sliding block, the protrusion on the upside of the scotch
The slide opening being arranged in the middle part of sliding block is stretched out, the convex block of one side resists one end of sliding block, and the opposite side of the scotch passes through
Steel ball is connected with compressed spring, and the side of the compressed spring abuts the link block being slidably installed, the link block it is upper
Side is disposed with sliding slot, the sliding slot and sliding block interlaced arrangement.
As a kind of supplement of telescopic rod described in the utility model, the sliding block is L-shaped, and hook portion accumbency is simultaneously slided
It is arranged in sliding slot, top accumbency and close scotch.
As a kind of supplement of telescopic rod described in the utility model, the protrusion matches with location hole.
As a kind of supplement of telescopic rod described in the utility model, the contact site of the scotch and steel ball is by two pieces
Inclined scotch panel I and scotch panel II intersect composition.
Advantageous effect
The utility model is related to a kind of self locking expansion bar, by the protrusion of scotch can the self-locking in location hole, can not
RestPose, and continue to direction of extension move can automatic unlocking, original length can be contracted after unlock.

Specific embodiment
With reference to specific embodiment, the utility model is elaborated, so that the advantages of the utility model and spy
Sign can be easier to be readily appreciated by one skilled in the art, and more specifically be defined so as to be made to the scope of protection of the utility model.
In addition, following embodiments are only the technical concepts and features for illustrating the utility model, its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement according to this, and the scope of protection of the utility model can not be limited with this, all
According to the spirit of the present invention substantially equivalent change or modification for being made, should all cover the scope of protection of the utility model it
It is interior.
As shown in Figs 1-4, the embodiment of the utility model is related to a kind of self locking expansion bar, including outer tube 1, inner tube 2
With sliding block 3, the outer middle side part of the outer tube 1 is equipped with location hole 8, and internal slide is socketed with inner tube 2, the inner tube 2
Side be slidably fitted with sliding block 3, the downside of the sliding block 3 is rotatablely equipped with scotch 4, the protrusion of 4 upside of the scotch
41 stretch out the slide opening 31 for being arranged in the middle part of sliding block 3, and the convex block 42 of one side resists one end of sliding block 3, the scotch 4 it is another
Side is connected by steel ball 5 with compressed spring 6, and the side of the compressed spring 6 abuts the link block 7 being slidably installed, described
The upside of link block 7 be disposed with sliding slot 71, the sliding slot 71 and 3 interlaced arrangement of sliding block.
The sliding block 3 is L-shaped, and hook portion accumbency is simultaneously slidably arranged in sliding slot 71, top accumbency and close stop
Block 4.
The protrusion 41 matches with location hole 8.
The scotch 4 and the contact site of steel ball 5 are by two pieces of inclined scotch panels I 43 and scotch panel II 44
Intersect composition.
Embodiment
When with external force pull outward inner tube 2 when, link block 7, which is driven, to be moved together, the close scotch 4 one in link block 7
The side wall of the sliding slot 71 of side and the hook portion of sliding block 3 interact, and in the case where compressed spring 6, steel ball 5 drive, past with inner tube 2
Outer movement is rotated when protrusion 41 encounters location hole 8 and up, so as to fall into location hole 8, forms self-locking；Then again outward
Same direction moves, and protrusion 41 is returned under the pulling of link block 7 in inner tube 2, when then moving inner tube 2 toward negative direction, connection
Block 7, which is driven, to be moved together, and the hook portion of sliding block 3 is moved to 4 side of separate scotch in link block 7 relative to sliding slot 71 outward
Sliding slot 71 side wall and be in contact with the side wall of the sliding slot 71 of the side, and compressed spring 6, steel ball 5 drive under, with inner tube
2 back move, and since convex block 42 is withstood by the top of sliding block 3, cause the protrusion 41 to will not fall into location hole 8.So this is stretched
Contracting bar realizes unidirectional auto-lock function, brings great convenience to life.
