Description
The utility model relates to a kind of exercising device of privileged site of suitable human body, relates in particular to a kind of physical training exercising device of training lower limb.
Now comparatively widely used back-pedal formula leg workout device mainly comprises two types of the barbell chip training aids of the pouring weight formula of wire rope pulley transmission and linear bearing kinematic pair, and this type of sports equipment mainly is to utilize the make progress strength of back-pedal of human body shank to overcome the load that pouring weight or disc provide.Reach and allow the user strengthen leg power, strengthen the movement effects of leg muscles.In the pouring weight formula training aids of wire rope pulley transmission, it moves through the shank back-pedal and makes the wire rope pulley transmission lead the whole pouring weight of adjustable number to realize, in actual use, has that the cable wire frequency of utilization is high to be damaged easily.Need frequent the replacing, the deficiency of maintenance just in case cables break takes place, also causes athletic injury easily; In the disc training aids of linear bearing kinematic pair, it moves through the trainer and directly pedals along the frame of pedaling of guide rod moving linearly and realize.Disc is loaded on to be pedaled on the frame.The guide rod direction is consistent with the direction of kicking one's legs.Pedal the frame guide rod and adopt the linear bearing transmission, its weak point is to have adopted 4 dish linear motion bearings, and accuracy of manufacture height, bearing are expensive again, caused the increase of product cost and the complexity of structure, and in use, the bearing noise are difficult to also overcome.
The purpose of this utility model promptly is to provide a kind of back-pedal formula leg workout device, avoiding the pouring weight formula training aids frequent maintenance and the potential safety hazard of wire rope pulley transmission, and can avoid the linear bearing kinematic pair barbell chip training aids labyrinth and use noise.
The purpose of this utility model is achieved through the following technical solutions: comprise base, back cushion, handrail, the backrest arm, disc, pedal frame, fore-stock, the barbell support, connecting rod, mounting, wherein: adjustable pipe arranged with base links together, mounting, fore-stock, handrail backrest arm, adjustable pipe and backrest arm and mounting decline and back cushion are fixed together, the barbell support that links to each other with fore-stock, the connecting rod other end with pedal frame and connect together, the base both sides are provided with the handrail that is the U font, connecting rod and mounting support body are in the shape of the letter V, and base and fore-stock body are the U font.With fore-stock that base links to each other on be provided with two place's symmetric arrangement gripper shoes, have on the gripper shoe be the height direction and before and after two connecting holes that stagger; The barbell support is L shaped parts; Its two ends and centre all are penetrated with a pipe, pipe two ends dress sintered metal powder bearing (have an end not adorn bearing, but be provided with connecting flange, be used for connecting with the barbell pipe that is provided with adpting flange equally); Pedal the set square that the backboard face is welded with two symmetric arrangement of pedaling of frame, two pitch-rows and the identical connecting hole of aforementioned gripper shoe pitch-row are arranged on the set square; Other has two two ends to be welded with the connecting leg of pipe.The all interior dress sintered metal powder bearing in the two ends of different pipe.On training aids, the pipe in the middle of the barbell support runs through with the connecting hole of two gripper shoe front ends by rotating shaft and connects, and can rotate around the axis; The pipe of the barbell support other end then links to each other with another connecting hole of gripper shoe, set square by rotating shaft, about each one, formed the motion of whole parallel double rocking bar thus.Described fore-stock is provided with the connecting plate of two symmetric arrangement, the connection holes that be distributed with two front and back on the connecting plate, just staggers, wherein be high, the place ahead to connecting hole link to each other with the middle tube of barbell support, be low, rear to connecting hole link to each other with the tube of connecting rod one end, sintered metal powder bearing all is equipped with at two ends at each tube, its connection is the rotating shaft that runs through bearing from the outside, and the rotating shaft two ends are all fixed threadably; The described plate of pedaling of pedaling frame adopts the Tofu pudding steel plate to make, pedaling frame forms with the set square of being located at two symmetric arrangement pedaling the backboard face by pedaling plate, two connecting holes identical with the connecting plate pitch-row are arranged on the set square, wherein the front end connection holes connects by the tube of rotating shaft with the barbell support, the rear end connection holes connects with the tube of connecting rod, and connecting mode is identical with the connecting mode of aforementioned connecting plate.
Described fore-stock except that the bottom with the base front end connects, tiltedly stretching out two inclined tubes again links to each other with the transverse tube of base, inclined tube is provided with two rubber blankets, spacing when being used for the barbell support and being in lower limit at the volley, eliminate motion noise simultaneously, described each rotating part all is equipped with sintered metal powder bearing, can eliminate the noise in the motion, described barbell support one end runs through the pipe two ends of stretching out both sides and is equipped with connecting flange, the disc Guan Yiduan that disc is installed also is provided with connecting flange, in use, the disc pipe connects with the barbell support by connecting flange.Run through a pachydermia pipe again as " bursting tube " at disc pipe and barbell support pipe inside.Described back cushion can be done the adjusting at angle of inclination by the adjustable pipe that connects backrest arm and base rear end; The two ends of rotating shaft are affixed with nut, and nut is equipped with hemispheric protective cover outward.
The utility model has the advantages that, by connecting rod, barbell support, pedal the motion that frame, fore-stock have been formed the parallel double rocking bar, avoided the use of linear bearing, spacing rubber blanket uses the noise of having avoided using lower limit, the sintered metal powder bearing at rotating shaft position makes the motion noiselessness, the load mode of disc has been avoided the wire rope pulley transmission, has exempted frequent maintenance and potential safety hazard.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Fig. 1 is a stereo appearance figure of the present utility model.
Fig. 2 is the profile of rotating shaft part.
Fig. 3 is the profile that the barbell support connects with the disc pipe.
Please referring to Fig. 1, it is a stereo appearance figure of the present utility model, by seeing among the figure, back-pedal formula leg workout device of the present utility model mainly by barbell support 1, connecting rod 2, pedal frame 3, fore-stock 4 has been formed the parallel double endplay device, can realize the motion of back-pedal, an end of the extension disc of barbell support 1 is put on the connection inclined tube that fore-stock 4 tiltedly stretches out as can be seen from Figure; Wherein there is a rubber blanket to play buffering and sound deadening on the inclined tube; Base 5 and fore-stock 4 support bodys are " U " from scheming as can be known; Connecting rod 2 is V-shaped with mounting 6.Handrail 7 on the base is " U " shape, simultaneously, it can also be seen that by Fig. 3, and back cushion 8 can be done the adjusting at angle of inclination by the adjustable pipe 10 that is connected in backrest arm 9 and base 5 rear ends.Barbell folder 17 between barbell 16 and the disc pipe 14 in case disc come out.
