Described foot-driven machine structure comprises foot rest and slide bar, foot rest is connected with slide bar, slide bar is fixed by limited block, and under the constraint of limited block, the degree of freedom that only there is above-below direction, the slide bar lower end is wedge shape, slide block is vertical with slide bar to be arranged, the contact jaw of slide block and slide bar is wedge shape, and its lozenges coordinates with slide bar lower end lozenges.
Be provided with spring between described foot rest and limited block, for resetting of foot-driven machine structure.
Described slide block is arranged in stopper slot, and stopper slot is arranged on fixed head.
The beneficial effects of the utility model are:
The utility model can allow hand that deformity is arranged or take on hand the people of full article to be convenient to open the door, and has facilitated daily life.Especially the warehouse keeper and the shop worker that needs are frequently passed in and out to drill shack have larger Practical significance.The utility model is simple in structure, easy to operate, has higher market popularization value.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the reference view that the utility model is used state;
The structural representation of this utility model when Fig. 2 is the door leaf closure state;
The structural representation of this utility model when Fig. 3 is the door leaf opening;
The structural representation that Fig. 4 is another visual angle of the utility model.
In figure: 1, foot-operated door opener; 2, door leaf; 3, doorframe; 4, body of wall; 5, floor; 11, holder; 12, connecting rod; 13, crank; 14, bearing support; 15, gear shaft; 16, slide block; 17, limited block; 18, spring; 19, foot rest; 20, fixed head; 21, stopper slot.
The specific embodiment
As shown in Figures 1 to 4, foot-operated door opener 1, comprise gear shaft 15, the slide block 16 with tooth bar, crank 13 and connecting rod 12, described gear shaft 15 is fixing by bearing support 14, crank 13 1 ends are fixedly connected with gear shaft, and an end of the other end and connecting rod 12 is hinged, and the other end of connecting rod 12 is articulated on the holder 11 of door leaf 2, gear engagement on rack and pinion axle on slide block 16, described slide block 16 is connected with the foot-driven machine structure.The foot-driven machine structure is controlled the motion of slide block 16, and rotates by the rack drives gear, and the crank drivening rod is opened door leaf 2.
Described foot-driven machine structure comprises foot rest 19 and slide bar, foot rest 19 is connected with slide bar, slide bar is fixing by limited block 17, and under the constraint of limited block 17, the degree of freedom that only there is above-below direction, the slide bar lower end is wedge shape, slide block 16 is vertical with slide bar, slide block 16 is wedge shape with the contact jaw of slide bar, and its lozenges coordinates with slide bar lower end lozenges.
Be provided with spring 18 between foot rest 19 and limited block 17, for resetting of foot-driven machine structure.
Its mounting means is as follows, as shown in Figure 1, the described foot-operated door opener 1 of utility model is fixedly mounted on the body of wall 4 or floor 5 of doorframe 3 inboards, and connecting rod 12 is hinged with door leaf 2.
Its operating principle is as follows, as shown in Figure 2, lower foot rest 19 tramps with one's feet, the slope driving slide block 16 of slide bar is to the direction transverse movement away from slide bar, rack drives gear on slide block 16 rotates, and the gear driven gear shaft rotates, and gear shaft drives crank to the door leaf side oscillation, crank 13 promotes connecting rod 12, and door leaf is opened.Crank 13, connecting rod 12 and door leaf 2 form four-bar mechanism.After pin leaves foot rest 19, foot rest 19 is with moving slide-bar to reset under the effect of spring 18.But door leaf 2 is still in opening, and after manually door leaf cutting out, whole door opener resets.
If need to increase the automatic door-closing function, can get back to initial position by the four-bar mechanism that increases torsion spring at the gear shaft place or make by other means, reached the purpose of automatic door-closing.
