Description

Paint roller brush Technical Field The utility model relates to the technical field of paint construction auxiliary tool equipment, in particular to a paint roller brush. Background In paint construction, roller brushes are common painting tools that dip paint through a rolling brush body and roll on a wall surface to achieve uniform coating. However, the assembly gap between the rolling brush body and the bracket of the existing roller brush is large, so that paint is easy to infiltrate into the gap between the rolling brush body and the bracket. This not only causes the paint waste, can also influence the homogeneity of brushing because of paint pile up in the roll in-process, leads to even that the cylinder is blocked, rotates unsmoothly, reduces the efficiency of construction. In addition, the infiltrated paint is possibly adhered to the bracket after being dried, so that rolling resistance is further increased, the roller brush can be used only once, and cannot be reused, and construction cost is increased. Disclosure of utility model In order to solve the technical problems, the utility model provides a paint roller brush. The utility model adopts the technical scheme that: The utility model provides a paint roller brush which comprises a Y-shaped support and a brush body, wherein the brush body is rotatably connected between two end parts of the support, connectors are arranged at two ends of the brush body, mounting seats are respectively arranged at two end parts of the support, the mounting seats are matched with the connectors to form rotary connection, the connectors comprise a combining rod and a first sealing sleeve arranged outside the combining rod, a combining groove matched with the combining rod and a limiting sleeve matched with the end surface of the first sealing sleeve are arranged on the mounting seats, the combining rod is positioned in the combining groove to form rotary connection between the mounting seats and the connectors, the limiting sleeve is positioned outside the mounting seats, and the end surface of the first sealing sleeve is combined with the end surface of the limiting sleeve to form sealing between the mounting seats and the outer part of the combining surface of the connector.
