Description
Technical field
The utility model belongs to the body-building apparatus technical field, more particularly relates to the improvement of the secondary buffer mechanism of treadmill running frame.
Background technology
The shock-absorbing capacity of conventional electric treadmill running frame is poor, thereby the shank that injures the body builder easily knee actuator current amplifier especially.The patent application that the applicant's No. 200620008066.6 names are called " secondary buffer elevating folding treadmill " provides a kind of running board that better buffering elasticity is arranged, and the shank that can avoid injuring the body builder is the treadmill of knee especially.The patent application that the applicant's No. 200620010695.2 names are called " treadmill running frame adjustable secondary buffer mechanism " provides a kind of adjustable secondary buffer mechanism of elasticity that cushions.
But the buffering flexible adjustment amplitude of above-mentioned patent application is less, regulating effect not clearly, regulative mode is also complicated.And its buffering elasticity also awaits further improvement.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of secondary buffer mechanism of treadmill is provided.It has better buffering elasticity, and it is bigger to cushion the flexible amplitude of accommodation, and regulating effect is more obvious, and regulative mode is also simpler.
Treadmill comprise underframe, elevating mechanism, running frame, running motor, front and back roller bearing, running board, running band, stand, about pipe and instrument board and appliance controller.Between running board and the running frame a plurality of elastomers are installed.These elastomers are installed on the running frame, are positioned at the band both sides of running.It has increased the buffering elasticity of running board greatly, and this is once to cushion.
In order to achieve the above object, the utility model comprise above the left and right sides channled rail front end that is installed in elevating mechanism and between the base plate of underframe about compression spring and be installed on the base plate of underframe and lay respectively at left and right sides cushion pad adjuster below the channled rail of the left and right sides.The cushion pad adjuster comprise inside and outside two bearing pins, the middle part that are fixed on side by side on the base plate be articulated in respectively inside and outside two identical stripe board on inside and outside two bearing pins, respectively be articulated in small clevis pin with head in two cushion pads and vertical fixing two spring bases above the stripe board two ends outside respectively at stripe board two ends.Respectively have elongated slot in two spring bases, the semielliptic spring that upwards arches upward respectively is installed in the elongated slot.The height of cushion pad is higher than the height of stripe board.Each is fixing the upper end of two flexural springs on the biside plate of underframe, and the lower end of two flexural springs respectively is fixed with socket cap, and the socket cap of two flexural springs is pressed in respectively on two semielliptic springs.
Two cushion pads are rubber blanket.Rubber is lined with better elasticity, good buffer effect.
The compression spring has increased channled rail together with the buffering elasticity between lifting motor and running frame and the underframe, and the cushion pad between the base plate of left and right sides channled rail and underframe has further played cushioning effect again, Here it is secondary buffer.
Task of the present utility model comes to this and finishes.
The utlity model has better buffering elasticity, it is bigger to cushion the flexible amplitude of accommodation, and regulating effect is more obvious, and regulative mode is also simpler.It can be widely used in the places such as family, hotel, school, gymnasium.

The specific embodiment
Embodiment 1.A kind of secondary buffer mechanism of treadmill is as Fig. 1～shown in Figure 5.Treadmill comprises underframe 1, elevating mechanism 2, running frame 3, running motor, front and back roller bearing, running board 4, the band of running, stand 5, about managing 6 and instrument board and appliance controller 7.A plurality of elastomers 8 are installed between running board 4 and the running frame 3.These elastomers 8 are installed on the running frame 3, are positioned at the band both sides of running, and constitute once buffering.
Present embodiment comprise above left and right sides channled rail 9 front ends that are installed in elevating mechanism 2 and between the base plate 10 of underframe 1 about compression spring 11 and be installed on the base plate 10 of underframe 1 and lay respectively at left and right sides cushion pad adjuster 12 below the left and right sides channled rail 9.Cushion pad adjuster 12 comprise inside and outside two bearing pins 13, the middle part that are fixed on side by side on the base plate be articulated in respectively inside and outside two identical stripe board 14 and 15 on inside and outside two bearing pins 13, respectively be articulated in small clevis pin with head 16 in two cushion pads 17 and vertical fixing two spring bases 18 above stripe board 15 two ends outside respectively at stripe board 14 two ends.Respectively have elongated slot 19 in two spring bases 18, the semielliptic spring 20 that upwards arches upward respectively is installed in the elongated slot 19.The height of cushion pad 17 is higher than the height of stripe board 14.Each is fixing the upper end of two flexural springs 22 on the biside plate 21 of underframe 1, and the socket cap 23 that the lower end of two flexural springs 22 respectively is fixed with 23, two flexural springs 22 of socket cap is pressed in respectively on two semielliptic springs 20.
Two cushion pads 17 are rubber blanket.Rubber is lined with better elasticity, good buffer effect.
Consult Fig. 2.Spring base 18 above regulating among Fig. 2 inward makes following spring base 18 rotate to the outside.Cushion pad 17 above this moment is between the base plate 10 of left and right sides channled rail 9 and underframe 1, and following cushion pad 17 is positioned at the outside of left and right sides channled rail 9.The user is when running, and impulsive force affacts on the compression spring 9 through channled rail 1.Compression spring 9 forms buffering along with user's paces rhythm is compressed.After compression spring 9 was compressed to a certain degree, pressure was pressed onto on the top cushion pad 17 subsequently.Because of on the top cushion pad 17 more near the front portion of treadmill, that is it that the gradient of running frame 3 is descended is more, thereby this moment, buffering effect was big.
Consult Fig. 3.Spring base 18 below regulating among Fig. 3 inward makes top spring base 18 rotate to the outside.Cushion pad 17 below this moment is between the base plate 10 of left and right sides channled rail 9 and underframe 1, and top cushion pad 17 is positioned at the outside of left and right sides channled rail 9.The user is when running, and impulsive force affacts on the compression spring 9 through channled rail 1.Compression spring 9 forms buffering along with user's paces rhythm is compressed.After compression spring 9 was compressed to a certain degree, pressure was pressed onto on the following cushion pad 17 subsequently.Because of on the following cushion pad 17 further from the front portion of treadmill, that is it that the gradient of running frame 3 is descended is less, thereby this moment, buffering effect was little.
Embodiment 1 has better buffering elasticity, and it is bigger to cushion the flexible amplitude of accommodation, and regulating effect is more obvious, and regulative mode is also simpler.It can be widely used in the places such as family, hotel, school, gymnasium.
