A kind of safe banister described in the utility model, wherein: described restrictor bar and jack back are for be arrangeding in parallel.
A kind of safe banister described in the utility model, wherein: two extreme position angles of the swing movement of described restrictor bar and jack back are 90 °.
A kind of safe banister described in the utility model can be: two extreme position of the swing movement of described jack back are respectively arranged with limited block and limit switch.
A kind of safe banister described in the utility model can also be: the length of described long connecting rod should be greater than two times of reductor length of connecting rod.
A kind of safe banister described in the utility model can also be: two extreme position of the swing movement of described jack back are provided with two limited blocks, extreme position of swing movement at described jack back is provided with limit switch, and reductor connecting rod and another corresponding extreme position of jack back of driving at reducing gear are provided with limit switch.
The utlity model has following remarkable advantage: component are few, compare part with existing banister and reduce half, cost is low, can also stop at an arbitrary position, it is the safe banister of a kind of safety and steady and quick operation, the product period of motion of the present utility model is more than 3 seconds, and adopts contact switch, steadily noiseless, because its structure connects simply, easy to operate, have good value for applications.
Description of drawings:
Fig. 1: represent a kind of safe banister embodiment perspective view of the present utility model.
Wherein: 1 reducing gear; 2 reductor connecting rods; 3 lower position switch; 4 rotating shafts; 5 long connecting rods; 6 minor axises; 7 main shaft connecting rods; 8 main shafts; 9 upper limit position switch; 10 vertical limited blocks; 11 jack backs; 12 horizontal limited blocks; 13 restrictor bars; Motor 14; Bearing 15.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described further, but not as to qualification of the present utility model.
As shown in Figure 1, a kind of safe banister, comprise reducing gear 1, restrictor bar 13 that machine case body, motor 14 drive, be supported on the main shaft 8 in the cabinet by bearing 15 main shaft connecting rod 7 is housed, the other end of main shaft connecting rod 7 flexibly connects by the reductor connecting rod 2 that a long connecting rod 5 and reducing gear 1 drive, promptly long connecting rod 5 and reductor connecting rod 2 are flexibly connected, long connecting rod 5 and main shaft connecting rod 7 are flexibly connected by minor axis 6 by rotating shaft 4.Main shaft 8 two ends are respectively arranged with restrictor bar 13 and jack back 11, and described restrictor bar 13 and jack back 11 are for be arrangeding in parallel, and two extreme position angles of the swing movement of described restrictor bar 13 and jack back 11 are 90 °.An extreme position of restrictor bar 13 is perpendicular to the position on ground, another extreme position of restrictor bar 13 is the position that is parallel to ground, two extreme position angles of its swing movement are 90 °, two extreme positions of the swing movement of described jack back 11 are too: an extreme position is perpendicular to the position on ground, another extreme position is the position that is parallel to ground, and two extreme position angles of its swing movement are 90 °.Two extreme position outsides at jack back 11 are respectively arranged with horizontal limited block 12 and upper limit position switch 9.The length of described long connecting rod 5 should be greater than two times of reductor connecting rod 2 length, the two ends of long connecting rod 5 are movably connected in an end of reductor connecting rod 2 and an end of main shaft connecting rod 7 respectively, when 2 rotations of reductor connecting rod, long connecting rod 5 one ends are with 2 rotations of reductor connecting rod, the other end drives main shaft connecting rod 7 and shakes, main shaft connecting rod 7 drives main shaft 8 rotations shakes restrictor bar 13 and jack back 11, because level has the restriction of limited block 12, restrictor bar 13 is shaken in 90 ° of scopes.
Safe banister of the present utility model is provided with and is used for the limit switch that initial sum stops, be provided with on the position and can also be designed at the upper and lower limit bit switch: two extreme position of the swing movement of described jack back 11 are respectively arranged with horizontal limited block 12 and vertical limited block 10, are provided with upper limit position switch 9 in extreme position of swing movement of described jack back 11.Reductor connecting rod 2 places that reductor drives, be provided with lower position switch 3 with the corresponding position of jack back 11 another extreme positions, as reductor connecting rod 2 below, promptly be lower position switch 3 to be set with the corresponding position of jack back 11 another extreme positions, can limit the position and the angle of jack back 11 swing equally, reach restrictor bar 13 levels and close banister, vertically open the action of banister.
Operating principle is as follows: reductor connecting rod 2 is driven by reductor and rotates 360 °, clockwise rotate or rotate counterclockwise and all can, when its from lowest part, the lower position switch place promptly is set rotates 180 °, and by rotating shaft 4 long connecting rod 5 is rotated 180 ° synchronously to the upper end simultaneously, the upper end minor axis 6 of this moment drives main shaft connecting rod 7 and upwards rotates 90 °, like this reductor connecting rod 2 again from 180 ° when 360 ° are rotated, long connecting rod 5 rotates along with rotation makes main shaft connecting rod 7, no matter reductor connecting rod 2 is just changeing or is reversing, main shaft connecting rod 7 is to fluctuate 90 ° on one side all the time, main shaft connecting rod 7 is to adopt taper bolt to link to each other with main shaft 8, main shaft 8 is fixedlyed connected with restrictor bar 13 by key, jack back 11 is fixedlyed connected with main shaft 8 by taper bolt, being provided with two bearings on main shaft 8 is fixed on the machine case body by support, main shaft connecting rod 7 fluctuates 90 ° and makes main shaft 8 drive restrictor bars 13 and jack back 11 rotate 90 °, simultaneously when restrictor bar 13 and jack back 11 run to the predefined extreme position of institute, be subjected to the restriction of horizontal limited block 12 and vertical limited block 10 and come and go and shake.
