The two sides for stating rotation axis extend to the outside of fixed link after gliding groove, and the rotation axis is located at left/right side and is also connected with rotation
Button.
Further technical solution is that the upper end of the spring contradicts the lower end side in clamping part, and lower end then contradicts
In the upper end side of fixed link, reset damping effect can be played in different sections.
Further technical solution is that the upper hopper chute and gliding groove are waist-shaped hole structure, and the body of rod can be made in upper cunning
It is freely moved up and down in slot and gliding groove, forms the range of a damping.
Further technical solution is that the left and right side of the rotation axis is respectively fixed with a limited block, prevents from rotating
Axis abjection, rotation axis and rotation axis can make screw-threaded coupling fixation be also possible to being directly welded to connect.
Further technical solution is, the telescopic rod bottom end is additionally provided with notch, the gear be located at notch inside and with
Teeth portion is connected, and the setting of notch can be engaged with holding gears and with teeth portion, and teeth portion is driven to move up and down.
Further technical solution is that the guide rail of vertical direction setting, institute are equipped at left and right sides of the lower end of the telescopic rod
The lower end two sides for stating fixed link are equipped with the guide-track groove that connection is slided up and down with guide rail cooperation, telescopic rod can be limited to and be moved down
In dynamic range.
The beneficial effects of the utility model are:
A kind of adjustable telescopic bar of the utility model, the structure can be stretched in fixed link up and down using telescopic rod, and
Its screen resilience is controlled by a spring, and telescopic rod can carry out gear under the turn of knob and drive fine tuning up and down, make spring
Elastic force be changed in a certain range, to be suitable for the use of different road conditions, compared to the existing damping being completely fixed
For effect, it can be achieved that different road conditions cooperate the damping effect of different spring forces, raising damping relevance factor makes user in motion
More comfortable safety.

Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Referring to FIG. 1 to 4, a kind of adjustable telescopic bar, including telescopic rod 1, fixed link 12 and spring 2, fixed link
12 is hollow structures and its outer sheath is slided up and down on telescopic rod 1 and with it and connect, and 1 top excircle of telescopic rod is fixed
Have a circle clamping part 9,2 sets of spring in 1 periphery of telescopic rod, 12 bilateral symmetry side of fixed link is respectively equipped with a upper hopper chute 3
With gliding groove 8, through there is a root cutting pin 4,4 both ends of bolt are located in the upper hopper chute 3 of two sides, stretch the medial side of telescopic rod 1
The bottom end side vertical direction of contracting bar 1 is equipped with teeth portion 10, and 10 side of teeth portion, which is connected, gear 5, and running through on gear 5 has one to turn
Moving axis 6, the two sides of rotation axis 6 extend to the outside of fixed link 12 after gliding groove 8, and rotation axis 6 is located at left/right side and is also connected with
There is knob 11.
The upper end of spring 2 contradicts the lower end side in clamping part 9, and lower end then contradicts the upper end side in fixed link 12, can
To play reset damping effect in different sections.Upper hopper chute 3 and gliding groove 8 are waist-shaped hole structure, the body of rod can be made upper
It is freely moved up and down in sliding slot 3 and gliding groove 8, forms the range of a damping.The left and right side of rotation axis 6 is respectively fixed with one
A limited block 7 prevents rotation axis 6 from deviating from, and rotation axis 6 can make screw-threaded coupling fixation be also possible to directly weld with rotation axis 6
Connection.1 bottom end of telescopic rod is additionally provided with notch 13, and gear 5 is located at 13 inside of notch and is connected with teeth portion 10, and notch 13 is set
Setting can be engaged with holding gears 5 and with teeth portion 10, and teeth portion 10 is driven to move up and down.It is equipped at left and right sides of the lower end of telescopic rod 1 perpendicular
For histogram to the guide rail 13 of setting, the lower end two sides of fixed link 12 are equipped with the guide-track groove 14 for cooperating with guide rail 13 and sliding up and down connection,
Telescopic rod 1 can be limited in the range of moving up and down.
In the present embodiment, teeth portion 10 is placed in the periphery of telescopic rod 1, then gear 52 sets of spring first
Side and held with a cord through gear 5, then the bottom end of telescopic rod 1 is placed into fixed link 12, at this moment spring 2
Upper end contradicts the lower end side in clamping part 9, and lower end then contradicts the upper end side in fixed link 12, then with bolt 4 through flexible
Upper hopper chute 3 on bar 1, bolt 4 and telescopic rod 1 can be screw thread and be fixed to each other, and be also possible to be welded in 4 two side ends of bolt
It is fixed, then rotation axis 6 is inserted into gear 5 after gliding groove 8 in the same way, and in 6 two sides of rotation axis with spiral shell
Line or the fixed limited block 7 of the form directly welded, and knob 11 is installed in the form of screw thread or welding on 6 one side of rotation axis
It extracts cord out in passing, then needs to be tightened in rotation axis 6 plus nut in the outside of knob 11 if it is screw thread, use
When, turn knobs 11, being driven by gear 5 teeth portion 10 and slides up and down telescopic rod 1 in a certain range, telescopic rod 1 by
In the cooperation of bolt 4 and guide rail 13, two o'clock determine straight line make telescopic rod 1 can only vertical shift in above-below direction, work as up time
When needle screws knob 11, telescopic rod 1 moves down and compresses spring 2, and the range that telescopic rod 1 moves up and down is reduced, and promotes bullet
Spring 2 sharply reduces the damping effect of telescopic rod 1, therefore, is suitble to travel on the road surface to lie low, and then just opposite counterclockwise
It is suitble to travel in concave-convex road surface, vehicle pitches at this time, keeps about 1 telescopic rod flexible, and upper hopper chute 3 and gliding groove 8 are distinguished
There is one end distance therefore, it is possible to provide the retractility of rebound improves damping effect.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work should all be covered subject to scope of protection of the utility model.
