The utility model relates to a postpositional lifting mechanism of a dynamic running machine with negative angle, which comprises a base, a bottom frame. The characteristics are as follows: one end of the bottom frame is movably hinged with the base; a lifting device and an auxiliary supporting device are arranged between the base and the bottom frame; the lifting device is arranged at the outer side and the auxiliary supporting device is arranged at the inner side; the lifting device is a lifter; the auxiliary supporting device comprises a supporting tube, a sliding groove and a sliding block; the lower end of the lifter is hinged with a lower bracket of the lifter fixed on the base; the upper end of the lifter is hinged with an upper bracket of the lifter fixed on the base; one end of the supporting tube is hinged with a lower bracket of the supporting tube fixed on the base, and the other end is connected with the sliding block; the sliding groove is installed at the bottom of the bottom frame; and the sliding block can freely slide in the sliding groove. The postpositional lifting mechanism of the dynamic running machine has advantages of simple and reasonable structure and good stability. In the utility model, the lifter, the supporting tube, the base and the bottom frame form a stable four-rod structure which greatly increases the stability of the whole machine and simplifies the lifting structure.
Description
Technical field
The utility model is specifically related to a kind of rearmounted power treadmill elevating mechanism that has negative angle.
Background technology
General commonly used preposition power treadmill is by underframe, base, and lifting arm, lift and lifting leg are formed.Underframe is hinged by the lifting arm and the lift upper end that are fixed on the underframe, and one of lift lower end and lifting midleg are point articulated.Lifting leg one end and underframe are hinged, and the other end links to each other with underframe.The screw rod of lift rotation drive sleeve elongation during work because lifting leg lower end is fixed on the base, is upwards risen so lift drives the front end of underframe.This kind structure is used in the preposition power treadmill without any problem, has advantages such as simple in structure and collapsible simultaneously.
But this kind structure applies in the rearmounted power treadmill and can produce following problem: rearmounted power treadmill especially requires the bigger treadmill of the gradient (for example 〉=40%) can require the length of the screw rod of lift and sleeve longer, structural member sizes such as the leg of lifting simultaneously increase relatively, cause the increase of the size and the weight of complete machine.Particularly in lifting process, the resistance to overturning of treadmill is bad, and higher to the requirement of strength of lifting screw.If the way of moving after adopting then the center of gravity of treadmill can't guarantee the center at complete machine.
The utility model content
The purpose of this utility model is to overcome above-mentioned problem and shortcoming, and a kind of succinct and rearmounted power treadmill elevating mechanism of being easy to realize is provided.
The utility model is achieved by the following technical solution:
It is a kind of rearmounted power treadmill elevating mechanism, comprise base, underframe, it is characterized in that underframe one end and base are movably hinged, also be provided with lowering or hoisting gear and auxiliary support apparatus between base and the underframe, lowering or hoisting gear is in the outside, auxiliary support apparatus is in the inboard, lowering or hoisting gear is a lift, auxiliary support apparatus comprises stay pipe, chute and slide block, the lift lower end is hinged with the lift lower carriage that is fixed on the base, and the lift upper end is hinged with the lift upper bracket that is fixed on the underframe, stay pipe one end is hinged with the stay pipe lower carriage that is fixed on the base, the other end is connected with slide block, and chute is installed in the bottom of underframe, and slide block can be free to slide in chute.
The lift lower carriage is positioned at the outer end of base, and the lift upper bracket is positioned at the centre position of underframe bottom, and the stay pipe lower carriage is positioned at the inner end of base, and chute is positioned at the inboard of lift upper bracket.
The stay pipe lower carriage is connected with the bridge-type unloading mechanism.
Slider bottom is provided with back-up block, and the upper end and the back-up block of stay pipe are hinged.
Lift described in the utility model is a prior art products, and the sleeve that has screw rod and match, lifter motor drive the screw rod rotation can make sleeve elongate or shorten, and realizes the lifting and the decline of underframe.
The utlity model has simple and reasonable, the advantage of good stability.The utility model is hinged with base and underframe front end, and lowering or hoisting gear has been installed in the rear portion of base, and lift drives the underframe lifting by screw rod and sleeve, sets up auxiliary support apparatus between base and the base, has solved the stability problem of rearmounted power treadmill.In the utility model, lift, stay pipe, base, underframe have formed four stable bar structures, and this structure has great raising to simplify lifting structure simultaneously to the stability of complete machine.Through experiment, underframe of the present utility model can be adjusted arbitrarily in 10 ~ 40 ° scope.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged diagram of the utility model chute and slide block.
As shown in FIG.: 1 base; 2 underframe; 3 bridge-type unloading mechanisms; 4 stay pipe lower carriages; 5 stay pipes; 6 slide blocks; 7 chutes; 8 back-up blocks; 9 lift upper brackets; 10 lift sleeves; 11 lifts; 12 lift lower carriages.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figure 1 and Figure 2: the left end of base 1 and underframe 2 is movably hinged, lift 11 and stay pipe 5 are positioned at base 1 and underframe 2, the sleeve that has screw rod on the lift 11 and match, lift 11 lower ends are hinged on the lift lower carriage 12, lift 11 upper ends are hinged on the lift upper bracket 12, lift lower carriage 12 is positioned at the outer end of base 1, and the lift upper bracket is positioned at the centre position of underframe 2 bottoms.Stay pipe 5 lower ends are hinged on the stay pipe lower carriage 4, stay pipe lower carriage 4 is positioned at the inner end of base 1, stay pipe lower carriage 4 links to each other with bridge-type unloading mechanism 3, the upper end of stay pipe 5 is connected with underframe 2 by slide block 6, chute 7, chute 7 is installed in the bottom of underframe 1, is positioned at the inboard of lift upper bracket 9.
When the utility model used: screw rod drove the sleeve elongation when lift 11 forward rotation, and it is the fulcrum lifting that makes progress with the lift bottom that underframe 2 is subjected to lift sleeve top thrust.Because underframe 2 liftings drive slide block 6 and stay pipe 5 upwards lifts certain angle.Slide block 6 is fixed on certain angle with stay pipe 5 when lift stops, and underframe 2 is played the supplemental support effect, and the pressure of 2 pairs of lift 11 screw rods of underframe and sleeve when having reduced motion has increased the stability of complete machine.Slide block 6 travels forward with underframe 2 whereabouts stay pipe 5 is fallen during lift 11 counter motions.
In this structure, lift 11, stay pipe 5, base 1, underframe 2 have formed four stable bar structures, and this structure has great raising to simplify lifting structure simultaneously to the stability of complete machine.
