Description

Technical Field

[0001] The present application relates to the technical field of testing instruments, and in particular to a building coating washability testing instrument. Background Art

[0002] The paint scrub resistance tester is a laboratory instrument specially used to test the scrub resistance of paint. It simulates the cleaning and wear conditions that paint may encounter during daily use to evaluate the durability of the paint.

[0003] The specific operating process of the paint scrub resistance tester is as follows: apply the paint on a cement board specimen of a specific specification, then place the cement board specimen on the paint scrub resistance tester. While continuously adding a specific scrubbing liquid, scrub the coating surface back and forth with a brush of a specific weight and a specific reciprocating speed until the bottom of the coating is exposed. The number of reciprocating brush strokes when the bottom is exposed is recorded as the test result.

[0004] The paint washability tester includes a mounting frame, and a brush is installed on the mounting frame. However, when the brush is currently installed on the mounting frame, the connection stability between the brush and the mounting frame is poor, which makes the brush more likely to shake and become unstable during the reciprocating washing process, resulting in the paint on the cement board specimen being washed by the brush. As a result, the paint on the cement board specimen is unevenly stressed during the process of being washed by the brush, thereby affecting the test results. Summary of the Invention

[0005] In order to improve the connection stability of a brush installed on a paint washability tester, the present application provides a building paint washability tester.

[0006] This application provides a building coating scrub resistance tester, which adopts the following technical solutions:

[0007] A building paint washability tester includes a frame, a mounting frame is slidably connected to the top of the frame, a mounting groove is provided on the top surface of the mounting frame, a brush is inserted into the mounting groove, the bottom surface of the brush is in contact with the top surface of the mounting frame, a protrusion is provided on the top of the brush, a cover plate is provided on the top surface of the brush, a groove is provided on the bottom surface of the cover plate, the protrusion on the top of the brush is adapted to be inserted into the groove, and buckling plates are respectively provided on one side of the two wide sides of the cover plate, the top surface of the buckling plate is detachably connected to the bottom surface of the cover plate, and the buckling plate is buckled to the outer wall of the mounting frame.

[0008] By adopting the above technical solution, the brush is inserted into the installation groove, and the bottom surface of the brush abuts against the top surface of the mounting frame. Under the action of the mounting frame, the brush is supported, thereby improving the connection stability between the mounting frame and the brush. The convex part at the top of the brush is adaptively inserted into the groove at the bottom of the cover plate, thereby limiting the top of the brush. Then, the cover plate and the mounting frame are buckled through the buckling plate, thereby fixing the outer shell in the cavity formed by the mounting frame and the cover plate, further improving the installation stability between the brush and the mounting frame. When the brush is reciprocatingly washing, the situation of the brush shaking unstably is reduced.

[0009] Preferably, connecting pieces are respectively arranged at both ends of the top surface of the cover plate. One end of each connecting piece passes through the cover plate, the buckling plate, the brush and the mounting frame at the same time, and the connecting pieces fix the cover plate, the buckling plate, the brush and the mounting frame.

[0010] By adopting the above technical solution, the connecting pieces fix the cover plate, the buckling plate, the brush and the mounting frame, thereby further improving the connection stability between the cover plate, the brush and the mounting frame.

[0011] Preferably, the buckling plate is a "C"-shaped plate.

[0012] By adopting the above technical solution, the buckling plate is a "C"-shaped plate. The inner wall of the top of the buckling plate abuts against the top surface of the brush and the top surface of the mounting frame, and the inner side wall and the inner bottom wall of the buckling plate abut against the outer wall of the mounting frame, thereby increasing the contact area between the buckling plate and the mounting frame, further improving the connection stability between the buckling plate and the mounting frame, and further improving the stability of the brush installed between the cover plate and the mounting frame.

[0013] Preferably, a placement groove is formed on the top surface of the frame, and a pressing frame is arranged on the top surface of the frame, and the pressing frame is located in the placement groove.

[0014] By adopting the above technical solution, after the coating is applied to the top surface of the cement board specimen, first take out the pressing frame from the placement groove, place the cement board specimen in the placement groove, and then place the pressing frame on the top surface of the cement board specimen. The pressing frame presses against the top surface of the cement board specimen, and the pressing frame presses against the periphery of the cement board specimen, thereby reducing the situation that the cement board specimen moves along the placement groove.

[0015] Preferably, a pressing component is arranged on the top surface of the frame, and the pressing component is used to press the pressing frame.

[0016] By adopting the above technical solution, the pressing component presses the pressing frame, thereby further applying pressure to the cement board specimen, improving the connection stability between the cement board specimen and the frame, and further reducing the movement of the cement board specimen along the placement groove.

[0017] Preferably, the pressing assembly includes a pressing seat and a fastener, the bottom of the pressing seat is clamped on the top of the frame, and one end of the fastener passes through the pressing seat and the top surface of the frame at the same time.

[0018] By adopting the above technical solution, the pressure seat is clamped on the top of the frame, and after the bottom surface of the pressure seat is abutted against the top surface of the pressure frame, the fasteners are tightened. The fasteners fix the pressure seat and the frame, so that the bottom surface of the pressure seat is pressed against the top surface of the pressure frame, thereby further applying pressure to the cement board specimen.

[0019] Preferably, a connecting groove is formed through the top surface of the pressing seat, the long side of the connecting groove is parallel to the long side of the pressing seat, and one end of the fastener passes through the connecting groove and is fixed to the frame.

[0020] By adopting the above technical solution, under the action of the connecting groove, after loosening the screw rod, the position of the pressing seat can be adjusted so that the pressing seat can better press the pressing frame.

[0021] Preferably, a handle is fixed to the top surface of the fastener.

[0022] By adopting the above technical solution, under the action of the handle, the operator rotates the handle, and the rotation of the handle drives the fastener to rotate, thereby facilitating the operator to rotate the fastener, thereby tightening or loosening the connection between the pressure seat and the frame.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The brush is inserted into the mounting groove, and the bottom surface of the brush is in contact with the top surface of the mounting bracket. Under the action of the mounting bracket, the brush is supported, thereby improving the connection stability between the mounting bracket and the brush. The protrusion on the top of the brush is adapted to be inserted into the groove at the bottom of the cover plate, thereby limiting the top of the brush. Afterwards, the cover plate and the mounting bracket are buckled together through the buckle plate, thereby fixing the shell in the cavity formed by the mounting bracket and the cover plate, further improving the installation stability between the brush and the mounting bracket, and reducing the shaking and instability of the brush during the reciprocating scrubbing process.

[0025] 2. The connector fixes the cover plate, the buckle plate, the brush and the mounting frame, thereby further improving the connection stability between the cover plate, the brush and the mounting frame. At the same time, after the connector is disassembled, the brush can be removed from between the cover plate and the mounting frame, thereby improving the convenience of disassembly and assembly between the brush and the mounting frame and the cover plate.
