Description
Technical field
The utility model relates to a kind of dust catcher, particularly a kind of road wheel of dust catcher.
Background technology
The usual configuration line travelling wheel of current existing dust catcher, under the rolling support of road wheel, dust catcher can be promoted or is drawn to operating position smoothly; Existing road wheel generally includes wheel rim, spoke and wheel shaft; Be rotationally connected between wheel shaft and spoke.
The shortcoming of this structure is, because connection diameter is less between rotating shaft and spoke, forms less radius of curvature, causes mutual wearing and tearing very fast, reduces whole road wheel working life, the final time between failures reducing whole dust catcher.
Utility model content
The utility model is to overcome defect in above-mentioned prior art, and the utility model provides a kind of road wheel of the dust catcher without rotating shaft, reduces the possibility that dust catcher road wheel produces fault, improves the service life of road wheel.
For achieving the above object, the utility model provides a kind of road wheel of dust catcher, comprising: wheel rim, spoke and gland; Wherein, wheel rim is circular ring structure, and the inner ring side of wheel rim is provided with the ladder of decline towards dust-absorbing element; Spoke is circular plate body structure, be embedded in the depression that wheel rim ladder formed, the axial end of spoke and the stepped surfaces of surface and wheel rim form matched in clearance, and wheel rim is rotated around spoke, spoke end face is provided with screw, is fastenedly connected by screw and dust-absorbing element; Gland, for Circular Thin structure, the diameter of gland is greater than the diameter of spoke and is less than the outer annular diameter of wheel rim, the end face of gland is provided with axially extended buckle or screw being greater than spoke diameter place, buckle or screw are two or more, spaced apart around axle center, and the surface of wheel rim is provided with corresponding bayonet socket or screw, buckle stretches in bayonet socket and is fastenedly connected or uses screw wheel rim and gland to be fastenedly connected wheel rim and gland, and wheel rim and gland rotate around spoke by the constraint of spoke.
In technique scheme, the surface of spoke is also provided with axially extended convex tendon, and convex tendon is a plurality of, and the axis uniform intervals around spoke distributes, and the surface of convex tendon is arc, when wheel rim is rotated and the friction of spoke reduce.
In technique scheme, wheel rim is provided with the second ladder around axis towards the end face of gland, and the second step diameter is corresponding with the diameter of gland, makes gland can embed in the second ladder, to keep the setting width of whole dust catcher, and to make dust catcher more attractive in appearance.
In technique scheme, described spoke is made up of polyformaldehyde (POM), to guarantee the anti-wear performance of spoke.
Compared with prior art, the utility model is connected by being embedded with wheel rim by spoke, reduce and be rotationally connected curvature between wheel rim and spoke, make between wheel rim and spoke be rotationally connected more reliable, improve whole road wheel working life, finally improve the time between failures of whole dust catcher; The convex tendon of spoke arranges the friction effectively reduced between spoke and wheel rim, and the loss of whole road wheel is reduced, and the resistance of rotation also reduces simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, a detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
Use steam of the present utility model to the road wheel of the dust catcher that food heats as shown in Figure 1, 2, 3, comprising: wheel rim 3, spoke 2 and gland 4, and wherein, wheel rim 3 is circular ring structure, and the inner ring side of wheel rim is provided with the ladder 31 of decline towards dust-absorbing element, spoke 2 is circular plate body structure (centre can part hollow out), be embedded in the depression that wheel rim ladder 31 formed, the axial end of spoke and ladder 31 surface of surface and wheel rim form matched in clearance, wheel rim 3 is rotated around spoke 2, spoke is made up of polyformaldehyde (POM), to guarantee the anti-wear performance of spoke, spoke 2 end face is provided with screw 22, is fastenedly connected by screw and dust-absorbing element 1, gland 4, for Circular Thin structure, centre is provided with hollow out, gland is made to form similar actiniform spoke structure, to reach effect attractive in appearance, the diameter of gland 4 is greater than the diameter of spoke 2 and is less than the outer annular diameter of wheel rim 3, the end face of gland 4 is provided with axially extended buckle 41 (or screw being greater than spoke diameter place, not shown), buckle 41 is four (being no less than two), distribute around axle center uniform intervals, the surface of wheel rim 3 is provided with corresponding bayonet socket 33 (or screw), buckle 41 stretches in bayonet socket 33 and wheel rim 3 and gland 4 is fastenedly connected (or using screw wheel rim and gland to be fastenedly connected), wheel rim 3 and gland 4 rotate around spoke 2 by the constraint of spoke 2.
Further as shown in Figure 2,3, the surface of spoke 2 is also provided with axially extended convex tendon 21, and convex tendon 21 is a plurality of, and the axis uniform intervals around spoke 2 distributes, and convex tendon 21 surface is arc, when wheel rim 3 is rotated and the friction of spoke 2 reduce.
Further as shown in Figure 1, 2, the second ladder 32, second ladder 32 diameter that wheel rim 3 is provided with around axis towards the end face of gland is corresponding with the diameter of gland 4, makes gland 4 can embed in the second ladder 32, to keep the setting width of whole dust catcher, and to make dust catcher more attractive in appearance.
Compared with prior art, the utility model is connected by being embedded with wheel rim by spoke, reduce and be rotationally connected curvature between wheel rim and spoke, make between wheel rim and spoke be rotationally connected more reliable, improve whole road wheel working life, finally improve the time between failures of whole dust catcher; The convex tendon of spoke arranges the friction effectively reduced between spoke and wheel rim, and the loss of whole road wheel is reduced, and the resistance of rotation also reduces simultaneously.
Be only a specific embodiment of the present utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
