Description

Technical Field

[0001] The utility model relates to the technical field of roller brushes, and more specifically to a roller brush capable of fixing the use pressure. Background Art

[0002] A roller brush, also known as a roller, is divided into three types: long-hair, medium-hair, and short-hair. It is a tool used for rolling paint over large areas. It is often used in daily architectural decoration projects when rolling paint over large areas. A roller brush needs to be used with a paint tray. Due to its wide rolling range, it is the most labor-saving and time-saving brush, especially when connected to an extension rod. It can easily paint high walls or ceilings. However, its disadvantage is that paint splashes easily. Therefore, the hair of the roller brush should not be too short, but must be thin, so that the paint film brushed out will feel delicate.

[0003] For example, the patent document with announcement number CN 218234213 U discloses an improved roller brush, including a roller brush head main body, a roller brush connecting rod and a roller brush handle, the roller brush head main body and the roller brush handle are connected through the roller brush connecting rod, the bottom end of the roller brush handle is fixed with a connecting shell, an external rod is arranged below the connecting shell, through the connecting shell provided at the bottom end of the roller brush handle, utilizing two symmetrical clamping blocks provided in the connecting shell to clamp the end of the external rod under the action of a spring, and cooperating with the three knobs triangularly arranged in the connecting shell to press the end of the external rod under the action of spiral rotation, so that the end of the external rod can be conveniently and stably connected to the bottom of the roller brush handle, and a person holding the external rod with his back to one end of the roller brush handle can lift part of the roller brush head main body for brushing operation.

[0004] However, when this structure is actually rolling the wall, it is often only possible to perform the squeezing and fitting operation between the roller and the wall by manually applying force. However, long-term high-intensity rolling operation can easily lead to uneven hand strength of the staff, resulting in uneven wall paint, which requires subsequent rework, which is time-consuming and labor-intensive. At the same time, the equipment cannot perform continuous paint operations for a more stable installation and cannot meet daily usage needs.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a roller brush with a fixed working pressure. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a roller brush with a fixed use pressure.

[0007] To achieve the above object, the utility model provides the following technical solution: comprising a U-shaped roller frame, the back of which is fixedly connected to a push rod frame, and the back of which is provided with an extrusion push rod;

[0008] A top fixing frame, wherein the interior of the U-shaped roller frame is movably connected with the top fixing frame via an extrusion push rod, and a roller brush body is arranged inside the top fixing frame;

[0009] A control rod is arranged at the back center of the U-shaped roller frame, the bottom end of the control rod is fixedly connected to a limited position seat, and a telescopic draw rod is arranged inside the control rod.

[0010] Preferably, damping rubber pads are arranged on both sides of the top end of the control rod, and a damping rotating shaft is arranged at the top end of the control rod.

[0011] Preferably, a material extraction pipe is provided at the bottom of the top fixing frame, and a paint cover is connected to the outer surface of the roller brush body.

[0012] Preferably, two ends of the top fixing frame are fixedly connected with sliding bars, and upper and lower ends of the sliding bar are fixedly connected with limit bars.

[0013] Preferably, a sliding groove is provided on the inner wall of the U-shaped roller frame, and limiting grooves are provided at the upper and lower ends of the sliding groove.

[0014] Preferably, both ends of the U-shaped roller frame are fixedly connected with fitting seats, and a limiting rolling ball is arranged inside the fitting seat.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the utility model, the U-shaped roller frame, the push rod frame, the extrusion push rod, the top fixing frame, the roller brush body, the sliding bar, the limit bar, the sliding groove, the limit groove, the fitting seat and the limit rolling ball can be used to enable the equipment to perform a fixed auxiliary pressure wall brushing operation. In actual use, the staff first docks the roller brush body inside the top fixing frame of the equipment onto the wall, and then performs a preliminary docking operation on the equipment as a whole through the U-shaped roller frame. At this time, the fitting seats and the limit rolling balls at both ends of the U-shaped roller frame can be adapted to the two end positions of the top fixing frame and the roller brush body, and then the extrusion push rod on the back of the push rod frame is started to drive the top fixing frame to perform a pressure test operation against the wall. During the pressure test, the two sides of the top fixing frame can perform a stable limited sliding operation with the sliding grooves and the limit grooves at both ends of the inner wall of the U-shaped roller frame through the sliding bars and the limit bars, thereby ensuring the stable progress of the pressure test, greatly improving the pressure stability of the subsequent roller brush body when brushing the wall, and reflecting the practicality of the equipment design.

[0017] 2. In the utility model, the overall use effect of the equipment is further improved through the U-shaped roller frame, the top fixing frame, the roller brush body, the control rod, the limit seat, the telescopic pull-out rod, the damping rubber pad, the damping shaft, the extraction pipe and the paint cover. In the daily use process, when the roller brush body inside the top fixing frame is painting the wall, the equipment can transport the wall painting paint into the paint cover through the extraction pipe at the bottom of the top fixing frame, and then evenly transfer it to the outer surface of the roller brush body to perform the wall painting operation, so that the equipment can perform stable and continuous wall painting operations. At the same time, the daily control rod can perform stable damping angle adjustment operations through the damping rubber pad and the damping shaft at the top. At the same time, the design of the limit seat and the telescopic pull-out rod allows the equipment to be freely adjusted in length, which reflects the comprehensiveness of the equipment design.
