Description
Technical field
It the utility model is related to telescoping tube interconnection technique field, and in particular to a kind of telescoping tube locking mechanism.
Background technology
Telescoping tube is more by outer tube, the inner tube of insertion outer tube and the locking mechanism group outer tube mutually to be locked with inner tube
Into.Existing locking mechanism realizes releasing and locking for inner tube and outer tube more by the way of bolt or torque spring, but on
State locking mechanism and the shortcomings of complicated, regulation is inconvenient, easy to wear, service life is short be present.
Utility model content
The purpose of this utility model is to provide a kind of telescoping tube locking knot simple in construction, easy to adjust and service life length
Structure.
To achieve the above object, the utility model employs following technical scheme：A kind of described telescoping tube locking mechanism,
Tapered end is coaxially arranged with after the inner tube insertion outer tube of telescoping tube, annular groove is provided with the outer circle wall of tapered end, in annular groove
Bottom land be outwards integrally extended with latch segment, the back side of latch segment is the arc card seamlessly transitted with the bottom land periphery of annular groove
Tight face, the arc clamping face are in that the cambered surface become larger from its bottom to the radial distance top and tapered end axis is set
To put, semiorbicular locking plate is provided with annular groove, the both ends of the locking plate are respectively arranged with inwardly projecting block projection, when
Inner tube synchronous drive tapered end from the lateral arc clamping face tip side in arc clamping face bottom rotate when, the arc of latch segment on tapered end
The top in clamping face can promote locking plate synchronous axial system together against the block projection of locking plate, and now inner tube can freely be moved along outer tube
It is dynamic；When inner tube synchronous drive tapered end rotates from the lateral arc clamping face bottom end side in arc clamping face top, in the arc of latch segment
During block projection of the shape clamping face by locking plate, the block projection of locking plate can be gradually displaced outwardly along arc clamping face
And locking plate is gradually outwards clamped on the inwall of outer tube, so as to which the inner tube of telescoping tube be mutually locked with outer tube.
Further, foregoing a kind of telescoping tube locking mechanism, wherein：Tapered end is integrally formed with latch segment.
The implementation of Pass through above-mentioned technical proposal, the beneficial effects of the utility model are：It is simple in construction, it is easy to adjust, it is not easy
Damage and service life length.

Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of described telescoping tube locking mechanism, the inner tube 1 of telescoping tube is inserted
Tapered end 3 is coaxially arranged with after outer tube 2, annular groove 4 is provided with the outer circle wall of tapered end 3, in the bottom land of annular groove 4 outside one
Body is extended with latch segment 5, and the back side of latch segment 5 is the arc clamping face 6 seamlessly transitted with the bottom land periphery of annular groove 4, institute
It is in that the cambered surface become larger from its bottom to the radial distance top and tapered end axis is set to state arc clamping face 6,
Semiorbicular locking plate 7 is provided with annular groove 4, the both ends of the locking plate 7 are respectively arranged with inwardly projecting block projection 8, when
The synchronous drive tapered end 3 of inner tube 1 from the lateral arc clamping face tip side in arc clamping face bottom rotate when, latch segment 5 on tapered end 3
The top in arc clamping face 6 can promote the synchronous axial system together of locking plate 7 against the block projection 8 of locking plate 7, and now inner tube 1 can edge
Outer tube 2 moves freely；When the synchronous drive tapered end 3 of inner tube 1 rotates from the lateral arc clamping face bottom end side in arc clamping face top,
During the arc clamping face 6 of latch segment 5 is by the block projection 8 of locking plate 7, the block projection 8 of locking plate 7 can be along arc
Clamping face 6 is gradually displaced outwardly and locking plate 7 is gradually outwards clamped on the inwall of outer tube 2, so as to by inner tube 1 and the phase of outer tube 2
It is locked；
Operation principle of the present utility model is as follows：
It is when adjusting 1 position of inner tube when inner tube 1 need to be made to be released with the phase of outer tube 2, inner tube 1 is lateral from arc clamping face bottom
Arc clamping face tip side rotates, and inner tube 1 understands synchronous drive tapered end 3 from the lateral arc clamping face tip side in arc clamping face bottom
Rotate, the top in the arc clamping face 6 of its latch segment 5 in rotation process of tapered end 3 can push away against the block projection 8 of locking plate 7
Dynamic locking plate 7 synchronous axial system together, now inner tube 1 can be moved freely along outer tube 2, i.e. the now relative position of freely adjustable inner tube 1
Put；
When needing to lock inner tube 1 with outer tube 2 after inner tube 1 is moved along outer tube 2 and adjusted to required position, by inner tube 1 from arc
The lateral arc clamping face bottom end side in clamping face top rotates, and inner tube 1 understands synchronous drive tapered end 3 from the lateral arc in arc clamping face top
Shape clamping face bottom end side rotates, on tapered end 3 during block projection 8 of the arc clamping face 6 of latch segment 5 by locking plate 7,
The block projection 8 of locking plate 7 can gradually be displaced outwardly along arc clamping face 6 and locking plate 7 is gradually outwards clamped in outer tube 2
On wall, so as to which inner tube 1 and the phase of outer tube 2 are locked.
The utility model has the advantages that：It is simple in construction, it is easy to adjust, it is hardly damaged and service life is grown.
