The specific embodiment
Below in conjunction with embodiment the utility model is done further explain.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model provides a kind of roll wheel assembly to comprise holder 1, support 2, wheel 3, and wheel 3 is connected with support 2 through a transverse axis 4; Said support 2 and hold in the palm 1 between connect through vertical pivot 5, the top of said vertical pivot 5 with ask 1 to captive joint, vertical pivot 5 middle and lower parts are provided with annular notch 7; Vertical pivot 5 bottoms are provided with 6 rotatable cooperations of axle mounting hole that an opening makes progress with support 2, and support 2 bottoms are provided with pin block mounting groove 8, are provided with through hole 12 between said pin block mounting groove 8 and the axle mounting hole 6; Said through hole 12 positions are corresponding with annular notch 7 positions of vertical pivot 5, and support 2 is provided with pin block 9, screw 13, tapped bore 14 and spring 15, and said pin block 9 is provided with pin block slotted eye 9-1; Pin block 9 is provided with inclined-plane 9-2 near the upper end of vertical pivot 5 positions, and said screw 13 tops are drive screw 13-1, and screw 13 middle and lower parts are not threaded pin 13-2; The diameter of said pin 13-2 is bigger than drive screw 13-1; And the length of pin 13-2 is longer than the height of pin block 9, and screw 13 passes pin block slotted eye 9-1 pin block 9 can be installed in the pin block mounting groove 8 slidingly, and the drive screw 13-1 of screw 13 matches with tapped bore 14; The pin 13-2 of screw 13 matches with the pin block slotted eye 9-1 of pin block 9; Said spring 15 also is installed in the pin block mounting groove 8 and the elastic force that provides pin block 9 to move to vertical pivot 5 directions, and the end of pin block 9 band inclined-plane 9-2 passes through hole 12 entering annular notch 7 and matches with annular notch 7, during installation; Can first independent installation support 2; On support 2, screw 13 is passed pin block slotted eye 9-1 and change in the tapped bore 14, pin block 9 and spring 15 are installed in the pin block mounting groove 8, pin block 9 passes through hole 12 and gets into axle mounting hole 6 under the effect of spring 15; Again vertical pivot 5 related holders 1 are fit in the axle mounting hole 6 on the support 2; The lower surface of vertical pivot 5 is connected on the inclined-plane 9-2 of pin block 9, continues vertical pivot 5 is backed down pin block 9 to the right, when the annular notch 7 of vertical pivot 5 moves to pin block 9 same level attitudes; Pin block 9 passes through through hole 12 once more and gets into annular notch 7 under the effect of spring 15; Thereby prevent that vertical pivot 5 from deviating from from axle mounting hole 6, the whole erection process is very simple and convenient, therefore this roll wheel assembly have simple in structure, productive costs is low, easy for installation, work efficiency is high, rotation is flexible, the characteristics of shock-resistant, long service life.
Like Fig. 1, shown in Figure 2; Said vertical pivot 5 middle and upper parts are provided with boss 11; The upper table surface 11-1 of boss 11 matches with holder 1; Boss 11 following table 11-2 are to the degree of depth of the distance between vertical pivot 5 bottom end faces greater than the axle mounting hole 6 on the support 2; Such structure setting is when abutting to 6 bottoms, axle mounting hole of support 2 at vertical pivot 5 bottom end faces; The holder 1 of the following table 11-2 of the boss 11 on the vertical pivot 5 and upper table surface 11-1 upper end breaks away from the support upper end, and the friction force of whole roll wheel assembly only occurs in 6 bottoms, axle mounting hole of vertical pivot 5 bottom end faces and support 2, avoided support 2 with hold in the palm 1 in addition the friction between support 2 and the vertical pivot 5 following table 11-2 have influence on the rotation alerting ability of roll wheel assembly.
Like Fig. 1, shown in Figure 2, said vertical pivot 5 bottom end faces curved surface shape spherical in shape, such structure can be so that the friction between vertical pivot 5 and the axle mounting hole 6 be stressed more even, and is wear-resistant and friction force is little, thereby makes the long service life of roll wheel assembly and rotate flexibly.
Like Fig. 1, Fig. 2, Fig. 4, shown in Figure 5; The annular notch 7 upper surface 7-1 of said vertical pivot 5 arrive the distance between 6 bottoms, axle mounting hole to the distance between vertical pivot 5 bottom end faces greater than through hole 12 upper surfaces; The annular notch 7 concave surface 7-2 of vertical pivot 5 arrive the distance between 6 bottoms, axle mounting hole to the distance between vertical pivot 5 bottom end faces less than through hole 12 lower surfaces; When pin block 9 penetrated through via holes 12 snapped in annular notch 7 after such structure made and to install not can with annular notch 7 upper surface 7-1 or concave surface 7-2 direct contact, thereby having avoided effectively taking place to rub between the upper surface 7-1, concave surface 7-2 of pin block 9 and annular notch has influence on the rotation alerting ability of roller set.
Like Fig. 1, Fig. 2, shown in Figure 6; Be provided with annular iron wash 10 between vertical pivot 5 bottom end faces and 6 bottoms, axle mounting hole; Annular iron wash 10 can play wear-resistant, impact-resistant effect, and area of contact is littler between vertical pivot 5 and the iron wash 10 simultaneously, and it will be more flexible rotating.
