Specific embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with the utility model reality
The attached drawing in example is applied, the technical solutions in the embodiments of the present invention are clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Example is applied, every other embodiment obtained by those of ordinary skill in the art without making creative efforts is all answered
When the range for belonging to the utility model protection.
As shown in Figs. 1-5, a kind of anticreep locking mechanism for telescoping tube, including outer tube 1 and in being set in outer tube 1
Pipe 2 is connected between the end and inner tube 2 of outer tube 1 by anticreep locking mechanism, and anticreep locking mechanism includes being bonded in 1 end of outer tube
First lock sleeve 3 in portion, connector sleeve 4, can be with the second lock sleeve 5 and locating part 6 of 4 synchronizing moving of connector sleeve.
The 3 top half inner wall of the first lock sleeve of hollow structure is Nian Jie with the outer wall of outer tube 1 or fixed in other forms connects
It connects, lower half portion inner wall forms second conical surface 31, and second conical surface 31 is in flaring structure from inside to outside, and second conical surface 31 extends to
The intersection of the lower end surface of first lock sleeve 3, top half and lower half portion forms step surface, under the step surface and outer tube 1
End face abuts against；The outer wall of first lock sleeve 3 forms external thread structure.
For the connector sleeve 4 of hollow structure through being socketed in inner tube 2, the outer wall of connector sleeve 4 has first conical surface 41, with the
Two conical surfaces 31 adaptation, i.e., the inclined direction of the two is on the contrary, tilt angle is suitable.The shape on the outer wall close to 4 lower end surface of connector sleeve
Circlewise groove 42, being engaged by clamping on the annular recess 42 has the protrusion 52 of the second lock sleeve 5.In the part of second lock sleeve 5
Have internal screw thread on wall, protrusion 52 is 5 bottom end of the second lock sleeve bulge-structure radially inward, and when assembly, protrusion 52 is along the
One conical surface, 41 slide downward realizes the connection of connector sleeve 4 and the second lock sleeve 5, dress until protrusion 52 is caught in annular recess 42
After matching, the internal screw thread on the second lock sleeve 5 is just threadedly coupled with the external screw thread on the first lock sleeve 3.
Locating part 6 is movably set in the outside of outer tube 1 comprising internal diameter is slightly larger than the planar annular of 1 outer diameter of outer tube
61, the neck 62 of extension is bent downward vertically and positioned at neck 62 far from 61 one end of planar annular from the inner wall of planar annular 61
Tapered protrusion 63, tapered protrusion 63 are in flaring structure structure from bottom to top, while in order to increase elasticity, neck 62 is uniform along one week
Multiple gap slots 621 are distributed with, which extends to tapered protrusion 63, and it is opening down, by taper
63 segmentation of protrusion forms multiple with larger elasticity, relatively independent structure.
As shown in figure 4, the upper end of the second lock sleeve 5 upwardly extends, so that when first conical surface 41 and second conical surface 31 are in
When locking state, the length of the second lock sleeve 5 still exceeds 3 part of the first lock sleeve, so that the first lock sleeve 3, second is locked
Set 5, outer tube 1 enclose and set to form a cavity 7, and the neck 62 and tapered protrusion 63 of locating part 6 are inserted into the cavity 7, planar annular
61 lower surface is in contact with the top surface of the second lock sleeve 5, with tapered protrusion 63 on corresponding position, the second lock sleeve 5
Inner wall is recessed inwardly to form annular slot 51, so that tapered protrusion 63 can be clamped in annular slot 51, realizes 6 He of locating part
The detachable of second lock sleeve 5 is connected.The second lock sleeve 5 of rotation is operated for the ease of user, is socketed with one on its external wall
A rubber ring 53.
The working principle of the utility model is: as shown in figure 4, hold rubber ring 53 covers the first lock sleeve of access from bottom to top
3 outsides, and rotate the second lock sleeve 5 upwards, are allowed to be threadedly engaged with the first lock sleeve 3 and connect, at this time first conical surface 41 and the
The cooperation of two conical surfaces 31, inner tube 2 and outer tube 1 are locked, and after locking, the locating part 6 by movable set in 1 outside of outer tube is caught in
Second lock sleeve, 5 end, also there are cavitys 7 between 3 top surface of locating part 6 and the first lock sleeve at this time；As shown in figure 5, needing to solve
When lock, holds rubber ring 53 and rotate the second lock sleeve 5 from top to bottom, second conical surface 31 loosens the locking to first conical surface 41, complete
At unlock, the inner tube 2 in outer tube 1 can be moved freely, when rotation offsets to locating part 6 and 3 top surface of the first lock sleeve, nothing
Method continues to rotate, i.e., the second lock sleeve 5 is without departing from the first lock sleeve 3.
Above-mentioned specific embodiment is used to illustrate the utility model, rather than limits the utility model,
In the spirit and scope of protection of the claims of the utility model, to any modifications and changes that the utility model is made, all fall
Enter the protection scope of the utility model.
