Description

Supporting frame adjustment structure

Technical field

The utility model relates to a kind of support structure, is meant a kind of supporting frame adjustment structure that has fast moving simultaneously concurrently and finely tune mobile effect.

Background technique

Habitual support structure, see also Fig. 1, pushing away 13 of seats under it is reached by last footstock 10, interior pipe 11, outer tube 12 forms, wherein should go up footstock 10 and be provided with end face 101, and the place is provided with connector portions 102 in end face 101 belows, and in connector portions 102, be provided with internal thread 103, so that an end of the outside thread 110 of interior pipe 11 is screwed together on the internal thread 103 of connector portions 102, and the other end of pipe 11 in this is screwed together in the internal thread 120 of outer tube 12, and forces interior pipe 11 in outer tube 12, to move up and down by rotation.Again, the other end surface of this outer tube 12 is provided with outside thread 121, for the connector portions 132 that pushes away down seat 13 in internal thread 133 screw togather mutually.

Though such scheme can be reached the purpose that originally set, still have following point to need further to improve:

One, because the adjustment of supporting frame is interlock between the internal thread of outside thread and outer tube of pipe in utilizing rotates and force interior pipe to move up and down, therefore, when supporting frame places body surface, and when the gap of end face between ceiling board of last footstock that makes supporting frame is too big, the number of times of the required rotation of pipe greatly increases in tending to make, and must continue to impose bigger strength can rotate, even can cause the unexpected injury of spraining because of the posture of firmly rotating is bad.

Two, hold as above-mentioned, because therefore its distance that pipe moves up and down in to be the rotation of armrest adjust, can make its speed that moves up and down be restricted, and then cause the overlong time of adjustment.

Three, hold as above-mentioned, unhandy situation took place when it also can cause withdrawal and pushing tow.

Summary of the invention

The utility model main purpose is, provide a kind of and be provided with the control group by the friendship place group that connects between interior pipe and outer tube, whether be the interlock shape, fast moving or fine motion adjustment up and down about whether doing with pipe in certain control between the screw section that has been inserted in the interior pipe in the axis hole of control group by control and the tooth portion of the limit body of the putting chamber that has been positioned at the control group.The utility model not only has fast moving and the mobile adjustment effect of fine setting simultaneously concurrently, also can make its operability easier fast outside, simultaneously, can also be applicable to the inclination utilization of various angles, and can have the effect of auxiliary clamping and positioning object, and then promote its working efficiency.
