Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Fig. 1 to Figure 14, this height adjustable cardan wheel, comprises black nut 1, adjusting bolt 2, mount pad 3, swinging strut 4, wheel support 8, roller 9; Wherein, wheel support 8 is two plate structures, and roller 9 is located at the lower end of wheel support 8 by axle, and namely between two plate lower ends, roller 9 relatively wheel support 8 can relatively rotate.
Mount pad 3 is disc structure, and the edge near disc structure is provided with fixed orifice, is arranged on bottom mobile device, for balanced sequence equipment by fixed orifice.Swinging strut 4 comprises transverse slat and is located at two risers of transverse slat opposite end, and wheel support 8 is located on the riser of swinging strut by rotating shaft, between two risers, and compact conformation.
Can relative rotary setting between mount pad 3 with swinging strut 4, swinging strut 4 can rotate around the axle center of mount pad 3, swinging strut 4 top is provided with protruding cylinder, the middle part of mount pad 3 has protruded upward cylindrical structure, cylindrical structure upper end is sealed end, cylindrical structure lower end is open end, and sealed end is provided with the hole passed for adjusting bolt; Mount pad 3 is enclosed within swinging strut 4, is provided with bearing between the outside face of the cylinder of swinging strut 4 and cylindrical structure inwall; The top of the transverse slat of swinging strut 4 is provided with protruding snap ring, snap ring is positioned at the outside of cylinder, be provided with groove inside the relative snap ring in mount pad 3 bottom, inside the snap ring of mount pad lower recess and swinging strut, be also provided with bearing, ensure the reliability that the axle center that swinging strut 4 is mounted opposite seat 3 rotates.
The center of the cylinder of swinging strut 4 is provided with runs through upper and lower tapped bore, tapped bore and adjusting bolt 2 suitable, adjusting bolt 2 is provided with the black nut 1 corresponding with mount pad, prevents adjusting bolt oneself in rotary moving; Be provided with the handle of convenient operation in adjusting bolt 2 upper end, during the overhang of adjustment adjusting bolt lower end relative swinging strut, directly rotated by handle, without the need to by other instrument.
Side, wheel support 8 top is located on swinging strut 4 by rotating shaft 6, and the relative swinging strut of wheel support is rotatable, regulates the height of roller.Rotating shaft 6 is positioned at the right side on wheel support 8 top, and adjusting shaft 7 is positioned at the left side on wheel support 8 top.
The lower end of adjusting bolt 2 is corresponding with wheel support, and contact position and the rotating shaft position of adjusting bolt 2 lower end and wheel support stagger.Be specially, wheel support 8 is provided with the adjusting shaft 7 corresponding with adjusting bolt lower end, and swinging strut 4 is provided with for the notch 10 spacing to adjusting shaft upper-lower position, and notch 10 is for being located at waist-shaped hole vertical on swinging strut 4.
Screw in adjusting bolt 2, adjusting bolt 2 is located at the adjusting shaft 7 on wheel support under pushing up, move downward on the left of adjusting shaft 7 driven wheel support 8, the rotating shaft 6 of wheel support 8 on swinging strut 4 rotates, when the lowermost position to notch on swinging strut 10 in rotary moving of the adjusting shaft 7 on wheel support 8 is put, restriction adjusting shaft 7 is rotated further and moves down by notch 10, and the now adjustment of cardan wheel highly reaches maximum height.
Because adjusting shaft 7, wheel support 8, roller 9 are conducted oneself with dignity reason, when cardan wheel is not adjusted to maximum height, can move down because of deadweight, for preventing arranging position limiting structure because deadweight moves down.
Spring plate 5 till position limiting structure, stop shell fragment 5 one end is located on swinging strut, and stop shell fragment 5 other end is positioned at the below of adjusting shaft 7, carries out resilient mounting to adjusting shaft 7.Stop shell fragment 5 on swinging strut 4 can be applied to adjusting shaft 7 power upwards, prevents adjusting shaft, wheel support, roller from moving down.
Or position limiting structure is the torsion spring 11 be enclosed within rotating shaft 6, the end of torsion spring 11 is stuck in the knock hole on wheel support 8, projection in the middle of torsion spring 11 withstands on the transverse slat bottom of swinging strut 4, applying bounce to wheel support 8, the resilience better effects if of torsion spring 11, preventing wheel support from moving down because conducting oneself with dignity.
When cardan wheel height regulates, only need rotate adjusting bolt 2, when adjusting shaft 7 is positioned at notch 10 upper extreme position place, cardan wheel is in minimum constructive height state H1, when adjusting shaft 7 is positioned at notch 10 lower limit position place, cardan wheel is in maximum height state H2, adopts adjusting bolt screw-in depth to carry out height and regulates, setting range can adjust arbitrarily within the scope of 10mm, effectively eliminates the problem that height that manufacturing errors and rolling wheel wear bring is inconsistent.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technical scheme are carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
