Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.
Referring to figs. 1 to Fig. 6, a kind of dustproof and waterproof bearing block, including having the bearing block ontology 11 of accommodating through-hole, the bearing
Seat 11 inner sidewall of ontology is disposed with the first annular flange 12 radially-inwardly stretched out.One end of first annular flange 12 forms position
Bearing bore 14 in accommodating through-hole, the bearing bore 14 is for placing bearing 42；First annular 12 other end of flange is disposed with diameter
To the second annular flange 13 inwardly stretched out, the internal diameter of the second annular flange 13 is less than the internal diameter of first annular flange 12.Bearing
Seat ontology 11 is disposed with the end cap 21 for covering bearing bore 14.
As shown in figure 5,41 end of shaft is placed in bearing 42, shaft 41 is equipped with the shaft shoulder, which is located at the second convex annular
In edge 13, the shaft shoulder is shaft conventional design.Preferably, having axial gap between 41 shaft shoulder of the second annular flange 13 and shaft
44 and radial clearance 43.
