Abstract
The utility model relates to a telescopic link in-place lock mechanism, consisting of a connector (3) and a think link (2) sliding in the connector (3). A plurality of round holes (10) are arranged on the connector (3) and steel balls (5) are arranged in the round holes (10). Locking round holes (9) matched with the steel balls (5) are arranged in the wall of the thin link (3). A positioning lug boss (12) is arranged at the lower end of the connector (3), a pressure spring (6) is arranged on the positioning lug boss, and a sliding sleeve (4) provided with an inclined inner lug boss (11) is arranged on the pressure spring (6); the steel balls (5) are pressed by the inclined surface of the inclined inner lug boss (11); and an axial elastic retaining ring (7) for preventing the steel balls (5) from sliding out is arranged on the top of the connector (3). The utility model which is easy in structure and convenient in dismounting and mounting can not be twisted with other parts; the resistance of the telescopic link in the stretching process is reduced because the relative sliding of telescopic links is changed into the rolling of the steel balls.
Description
Technical field
The utility model relates to a kind of flexible rod, is specifically related to a kind of flexible rod locking framework that puts in place.
Background technique
The flexible rod locking framework that puts in place is meant the mechanism that can realize stretching flexible rod, contract motion automatically locks after putting in place, in the reality again requirement can manually remove locking and be convenient to use repeatedly.At different needs, its form is varied.Only put in place locking framework and the utility model of other similar flexible rods of the present utility model compared explanation below.
For example, folded umbrella commonly used draws rear space in and design improvement on the original basis in order to save, can manually withdraw from locking so that use repeatedly, it adopts spring-pin principle, pin is in pre-locking state all the time under the spring force effect, pin snaps in the thickness bar under the spring force effect and is implemented to position locking after flexible rod launches to put in place.
But at similar annular net-shape antenna reflector because the inner dynamic rope of flexible rod exists, said structure easily and the reflector dynamic ropes tangle.
At the problems referred to above, the utility model mechanism utilizes cleverly that structural design has realized required function, and all parts all are installed in pipe fitting outer, and the situation of tangling with dynamic ropes can not take place.And the outline packages design is good, has avoided linked network.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of reasonable in design is provided, and removes and installs conveniently the flexible rod that can not take place to tangle with the pipe fitting internally-powered rope locking framework that puts in place.
For achieving the above object, the technical solution adopted in the utility model is: a kind of flexible rod locking framework that puts in place, form by joint and the thin bar that in joint, slides, joint is provided with a plurality of circular holes, be provided with steel ball in the circular hole, be provided with the locking circular hole that matches with steel ball in the thin rod tube wall, described joint lower end is provided with positioning boss, stage clip is installed on the positioning boss, sliding sleeve with oblique inner convex platform is installed on the stage clip, the inclined-plane compressing steel ball of oblique inner convex platform, nipple tip is equipped with the circlip for shaft that prevents that steel ball from skidding off.
Circular hole described in the utility model is evenly distributed on the joint.
The utility model compared with prior art has the following advantages: the utility model is simple in structure, is convenient to remove and install, and can not tangle with miscellaneous part; Slide relative between flexible rod changes the rolling of steel ball into, has reduced the resistance of flexible rod expansion process.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
Embodiment 1:
The locking framework that puts in place of a kind of flexible rod as shown in Figure 1, 2, thin bar 2 by joint 3 and slip in joint 3 is formed, joint 3 is provided with a plurality of circular holes 10, be provided with steel ball 5 in the circular hole 10, be provided with the locking circular hole 9 that matches with steel ball 5 in thin bar 2 tube walls, described joint 3 lower ends are provided with positioning boss 12, stage clip 6 is installed on the positioning boss 12, sliding sleeve 4 with oblique inner convex platform 11 is installed on the stage clip 6, the inclined-plane compressing steel ball 5 of oblique inner convex platform 11, joint 3 tops are equipped with the circlip for shaft 7 that prevents that steel ball 5 from skidding off.
Circular hole described in the utility model is 4, is evenly distributed on the joint tube wall.
The flexible rod locking mechanism that puts in place then is that the flexible rod locking framework that puts in place is installed in thick bar 1 termination, and at special position (decide on the situation of the putting in place) fluting of thin bar 2 or punch.Thin bar 2 slips into and then realizes the contraction of brace along thick bar 1 inner chamber, under the effect of steel ball 5 in the structure on opportunity that launches to put in place, snap in immediately in the locking circular hole 9 of thin bar 2 in external force, and restriction steel ball 5 radial displacement, realize the locking that puts in place of flexible rod.
Wherein, joint 3 is affixed with thick bar 1 termination, and all the other component and its assembling realize putting in place lock function.Design the circular hole 10 that circlip for shaft 7 mounting grooves is arranged, be used for steel ball 5 installations, the positioning boss 12 that is used for stage clip 6 axially locating on the joint 3.
The design key of sliding sleeve 4 is the design on its inwall and joint 3 tube wall surface of contact and inclined-plane, with the design limit of joint 3 tube wall surface of contact the footpath after steel ball 5 lockings outwards move; The design limit on inclined-plane before steel ball 5 locking footpath of (or after release) outwards move.
Steel ball 5, stage clip 6, circlip for shaft 7 are standard piece, buyable.Stage clip 6 can be realized the switching of mechanism's locking and releasing state as power source; Steel ball 5 plays the effect of pin at this; 7 effects of the sliding sleeve under the spring force effect 4 being played axial limiting of circlip for shaft.
The parts design details is as follows:
1, in the design of mechanism, the selection of joint 3 outer walls, 4 fit tolerances of sliding sleeve.Can not cause bigger frictional force by tension, only make that under the spring force effect, sliding sleeve 4 is difficult to even can't realizes by the switching of the state of not putting in place with the state that puts in place.Pine makes joint 3 and sliding sleeve 4 compoles be prone to stuck phenomenon excessively.The general Spielpassung of selecting
2, the control of locking circular hole 9 sizes on the thin bar 2.Can not excessively cause play between thick, thin bar, can not be too small, make mechanism reliability reduce.The general selection
(R is steel ball 5 radiuses)
3, the design of sliding sleeve 4 ramp angles.Its with steel ball 5 and joint 3 on the steel ball mounting hole between the relevant θ of coefficientoffriction＞arctg μ (θ is the angle of inclined-plane and substantially horizontal).
4, in the application of reality, suitable work helps the work of mechanism with lubricated.
