Abstract
The utility model relates to a folding joint which is used on a folding bracket and used for connecting two sections of adjacent branch pipes. The folding joint comprises a first sleeve for fixing a first branch pipe, a second sleeve for fixing a second branch pipe, a spring and an adjusting knob; a connecting part is respectively arranged on the first sleeve and the second sleeve; the connecting part of the first sleeve is provided with a through hole, and the inner end of the connecting part of the first sleeve is provided with first anti-rotating saw tooth patterns; the connecting part of the second sleeve is provided with a screw hole corresponding to the through hole, and the inner end of the connecting part of the second sleeve is provided with second anti-rotating saw tooth patterns meshed with the first anti-rotating saw tooth patterns; the outer end of the adjusting knob is provided with a rotating knob part, and the inner end of the adjusting knob is provided with a screw rod; and the screw rod at the inner end of the adjusting knob passes through the through hole and is in threaded connection to the screw hole of the second sleeve, and the spring is positioned between the outer end surface of the connecting part of the first sleeve and the rotating knob part. The folding joint is novel in structure and convenient to use and has a good effect, and the tightness of the connecting part does not need to be adjusted.
Description
Technical field
The utility model relates to a kind of being used on folding rack, connects the folding structure of adjacent two sections arms.
Background technique
Existing folding joint is considerably less and structure is single.The existing folding joint that is used on folding rack generally adopts hinging structure, and adjusts angle between adjacent arm by adjusting the hinge axis degree of tightness.The user needs first to unscrew hinge at every turn, and is urgent again after completing, thereby adjusts the folding angle between adjacent arm, and operation is trouble very.After this folding joint is repeatedly adjusted in addition, easily skid in hinged joint, poor stability, and using effect is bad.
Summary of the invention
Goal of the invention of the present utility model is for a kind of folding joint that is used on folding rack is provided, and this folding joint novel structure can adjust folding strength and stability suitable between adjacent arm, and easy to use, using effect is good.
In order to realize the foregoing invention purpose, the utility model has adopted following technological scheme:
A kind of for the folding joint on folding rack, comprise be used to the first sleeve pipe of fixing the first arm, for the second sleeve pipe, spring and the adjusting knob of fixing the second arm; Be equipped with a junction on the first sleeve pipe and the second sleeve pipe; The joint of the first sleeve pipe is provided with through hole, and the inner of this joint is provided with the first spline hackle mark; The joint of the second sleeve pipe is provided with the screw corresponding with through hole, and joint the inner of the second sleeve pipe is provided with the second spline hackle mark that is meshed with the first spline hackle mark; The adjusting knob outer end is knob section, and the inner is screw rod; The screw rod of adjusting knob the inner passes through hole and is threadedly connected in the screw of the second sleeve pipe, and spring is between the exterior edge face and knob section of joint of the first sleeve pipe.
As preferably, described the first spline hackle mark and the second spline hackle mark are all the hackle marks that launch centered by through hole or screw, radially.
Adopted the folding joint of technique scheme, this folding joint comprises be used to the first sleeve pipe of fixing the first arm, for the second sleeve pipe, spring and the adjusting knob of fixing the second arm.Be equipped with a junction on the first sleeve pipe and the second sleeve pipe, between the first sleeve pipe and the second sleeve pipe, the surface of contact of joint is provided with intermeshing first, second spline hackle mark, adjusting knob is fixed on spring in the outside of first set pipe jointing part, by the outer end of inside elasticity pressing the first sleeve pipe of spring, making between first, second spline hackle mark has interactional pressure.Therefore compare with existing folding joint, this folding joint novel structure, the strength that need only adjust spring just can adjust folding strength and stability suitable between adjacent arm, the operator need only bestow certain strength just can fold adjacent arm easily, need not adjust again the degree of tightness of joint, easy to use and effective.
Description of drawings

Fig. 2: the structural representation of the first sleeve pipe interior edge face in embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment: as depicted in figs. 1 and 2 a kind of for the folding joint on folding rack, this folding joint comprises be used to the first sleeve pipe 1 of fixing the first arm, is used for fixing the second sleeve pipe 2, spring 4 and the adjusting knob 4 of the second arm.
As depicted in figs. 1 and 2, the first sleeve pipe 1 is provided with cylindrical the first joint 11 in a cross section, the opening direction that the second sleeve pipe 2 is provided with cylindrical second joint 11, the first joints 11 and the axial its corresponding casing section of the second joint 11 is vertical mutually.The first joint 11 is axially arranged with through hole 111, and it is the hackle marks that launch centered by through hole 111, radially that the interior edge face of this first joint 11 is provided with the first spline hackle mark 110, the first spline hackle marks 110.The second joint 12 is provided with the screw corresponding with through hole 111 211, it is the hackle marks that launch centered by screw 210, radially that second joint 12 the inners are provided with the second spline hackle mark 210, the second spline hackle marks 210 that are meshed with the first spline hackle mark 110.When through hole 111 and axis hole 211 were corresponding, the first spline hackle mark 110 and the second spline hackle mark 210 also were meshed.Above-mentioned adjusting knob 4 outer ends are that knob section 30, the inner are screw rods 31.The screw rod 31 of adjusting knob 3 the inners passes in the screw 211 that through hole 111 is threadedly connected to the second sleeve pipe, spring 4 is pressed between the exterior edge face and knob section 30 of the first joint 11 by elasticity, the effect of spring 4 is that making between the first spline hackle mark 110, the second spline hackle mark 210 has interactional pressure from inside pressing the first joint 11 of the outer elastic of the first joint and the second joint 12.
During use, the operator rotates knob section 30, by the distance between the exterior edge face that changes knob section's 30 interior edge faces and the first joint 11, adjust the length of spring 4, thereby change the elastic pressure of spring 4, make pressure between the first spline hackle mark 110 and the second spline hackle mark 210 to suitable degree.Like this, both need the operator to bestow certain strength and regulated the first arm of being fixed on folding joint and the angle between the second arm, bring convenience to adjusting, allow again folding joint after adjusting under spring 4 and the effect of spline hackle mark, has certain load-bearing, spline strength, thereby it is constant to keep angle between the first arm and the second arm to stablize, and using effect is very good.
