The applicant's the patent No. is that ZL200520081005.8, publication number are that the Chinese patent that CN2797181, name are called " the bench height regulating mechanism of fitness equipments " is the bench height regulating mechanism of another kind of exercycle." regulating mechanism is by the fixed base 5 that is fixed on sliding tube 3 upper back; be installed in the last movable tongue 10 that its front end stretches out from top elongated slot 8 on the fixed base 5 with pivot 6; connecting rod 12 that is connected with last movable tongue 10 with upper pin 11; be installed in the pressure spring 13 between seat cushion stationary axle 4 lower end surfaces and connecting rod 12 upper-end surfaces; be welded on the shaft bearing plate 14 of sliding tube 3 bottom elongated slots 8 both sides; be installed in the little axle 15 on the Y-axis board 14 for it, being installed on the little axle 15 and from following movable tongue 16 and connection that sliding tube 3 bottom elongated slots 8 stretch out descends the lower bearing pin 17 of movable tongue 16 and connecting rod 12 to constitute." it is simple to operate, can auto lock, but structure is too complicated again, and cost of production is also high.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, the locking positioning mechanism that provides a kind of single knob to regulate.It is not only simple in structure, cost of production is lower, only with single knob-operated, easy to operate, and has locking and pretension positioning action, and adjusted positional accuracy and reliability are also high.
In order to achieve the above object, the present invention includes fixing square tube, be sleeved on the overcoat square tube on the fixing square tube, fixedly have a registration hole on the square tube, have a screw on the overcoat square tube, knob is installed in the screw.The top liner plate and the stiffening plate fixed successively of overcoat square tube, screw is positioned on the stiffening plate, has the hole concentric with screw on liner plate and the overcoat square tube.Also be fixed with the U-shaped seat on the overcoat square tube, a side of U-shaped seat is fixed with the pedestal that is used to install movable part, between the biside plate of U-shaped seat fastening about two bolt axis and nut.About in the middle of two bolt axis suit bushing pipe, two inside levers are installed respectively on two bolt axis about the two ends of bushing pipe.Have spring seat below the lever, suit pressure spring on the spring seat.Knob comprises screw rod and is fastened on handball on the screw rod with Cock screw.Suit and is positioned at below the handball neck end and is pressed in 4 pressing plates above the lever on the screw rod.
The left and right sides of pressing plate fastening respectively a locating stud, to prevent the rotation of pressing plate.About on two bolt axis suit two side plates that are positioned at U-shaped seat biside plate inboard, two side plates can prevent that lever from sliding along bolt axis.
Fixedly square tube above have the scale that table is annotated locked position.Have table above the handball and annotate the character of locking or loosening sense of rotation.Operation when this scale and character are convenient to regulate.
Task of the present invention comes to this and finishes.
The present invention is not only simple in structure, cost of production is lower, only with single knob-operated, easy to operate, and has locking and pretension positioning action, and adjusted positional accuracy and reliability are also high.It can be widely used in needs and adjust in the machinery and fitness equipments of relative position of two parts.
Description of drawings
Fig. 1 is a partial sectional view of the present invention.
Fig. 2 is its structural representation.
Embodiment
Embodiment 1.The locking positioning mechanism that a kind of single knob is regulated is as Fig. 1-shown in Figure 2.It comprises fixing square tube 1, be sleeved on the overcoat square tube 2 on the fixing square tube 1, fixedly has a registration hole 23 on the square tube 1, has a screw 24 on the overcoat square tube, in the screw 24 knob is installed.The top liner plate 10 and the stiffening plate 11 fixed successively of overcoat square tube 2, screw 24 is positioned on the stiffening plate 11, has the hole 22 concentric with screw 24 on liner plate 10 and the overcoat square tube 2.Also be fixed with U-shaped seat 3 on the overcoat square tube 2, a side of U-shaped seat 3 is fixed with the pedestal 4 that is used to install movable part, between the biside plate of U-shaped seat 3 fastening about two bolt axis 6 and nut 21.About in the middle of two bolt axis 6 suits bushing pipe 5, two inside levers 7 are installed respectively on two bolt axis 6 about the two ends of bushing pipe 5.Have spring seat 8 below the lever 7, suit pressure spring 9 on the spring seat 8.Knob comprises screw rod 13 and is fastened on handball 16 on the screw rod 13 with Cock screw 17.Suit below the neck end 25 that is positioned at handball 16 and is pressed in pressing plate 12 above 4 levers 7 on the screw rod 13.Liner plate 10 and stiffening plate 11 can strengthen intensity.
