The specific embodiment

Below in conjunction with embodiment the utility model is done further explain.

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, 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 is provided with a pin hook mounting groove 8, is provided with through hole 12 between said pin hook 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 hook 9, and said pin hook 9 comprises lifting-hook 9-1 and horizontal hook 9-2; Pin hook 9 is installed in the pin hook mounting groove 8; Support 2 sides are provided with screw 13 and tapped bore 14, and said tapped bore 14 links with pin hook mounting groove 8, and said screw 13 cooperates with the lifting-hook 9-1 butt of pin hook 9; And the horizontal hook 9-2 of pin hook 9 passes through hole 12 entering annular notch 7 and matches with annular notch 7; During installation, will sell hook 9 earlier and be placed in the pin hook mounting groove 8, again vertical pivot 5 related holders 1 will be fit into axle mounting hole 6; And then screw 13 changed in the tapped bore 14; Screw 13 is connected to that lifting-hook 9-1 goes up and pushing pin hook 9 moves to vertical pivot 5, makes the horizontal hook 9-2 penetrated through via holes 12 of pin hook 9 get into annular notch 7, thereby prevents that vertical pivot 5 from deviating from from axle mounting hole 6; The whole erection process is very simple and convenient, therefore this a kind of novel 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. 3, shown in Figure 4; 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 the horizontal hook 9-2 penetrated through via holes 12 of selling hook 9 after such structure makes and to install gets into annular notch 7 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 hook 9 and annular notch has influence on the rotation alerting ability of roller set.

Like Fig. 1, Fig. 2, shown in Figure 5; 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.
