Description

Technical Field

[0001] The utility model relates to the technical field of sealing brush detection, in particular to a pressure testing device. Background Art

[0002] A sealing brush is a special brush that is usually composed of densely arranged bristles and a brush head or base that supports the bristles. The main function of a sealing brush is to form an effective seal between equipment, components or structures through the dense arrangement and elasticity of the bristles to prevent the intrusion or leakage of dust, liquid, gas, impurities, etc.

[0003] Existing pressure testing devices can evaluate the strength and stability of the bristles when subjected to external forces by applying pressure to the bristles. They can only focus on testing the compressive performance of the bristles and evaluate their bearing capacity by applying pressure, but cannot simultaneously detect their sealing performance. Therefore, they cannot meet the problem of testing the sealing performance of the sealing brush. Utility Model Content

The detection mechanism 2 includes a sliding frame 209 slidably connected to the outer surface of the shell 1, the outer surface of the sliding frame 209 is fixedly connected to the second electric telescopic rod 212, the output end of the second electric telescopic rod 212 is fixedly connected to the detection frame 203, the inner wall of the detection frame 203 is slidably connected to the detection plate 206, and the inner wall of the detection frame 203 is fixedly connected to the pressure sensor 211.

[0025] In order to facilitate the detection of the pressure resistance and sealing performance of the sealing brush, a first electric telescopic rod 210 is fixedly connected to the inner wall of the shell 1, and the output end of the first electric telescopic rod 210 is fixedly connected to the outer surface of the sliding frame 209. By starting the first electric telescopic rod 210, the output end of the first electric telescopic rod 210 drives the sliding frame 209 to slide on the inner wall of the shell 1, and then the sliding frame 209 can drive the second electric telescopic rod 212 to slide, which is convenient for detecting brush wires of different lengths. The detection mechanism 2 also includes a fan 201 fixedly connected to the outer surface of the shell 1, and the lower surface of the fan 201 is fixedly connected to the wind hood 202, and the lower surface of the wind hood 202 is fixedly connected to the bellows 204, the other end of the bellows 204 is fixedly connected to a fixed frame 205, and the fixed frame 205 is fixedly connected to the upper surface of the detection plate 206. By starting the fan 201, the air flow generated by the fan 201 is blown to the outer surface of the brush filament through the wind collecting cover 202, the bellows 204 and the fixed frame 205, so as to facilitate the testing of the sealing of the brush filament. The outer surface of the sliding frame 209 is fixedly connected to the connecting frame 208, and the outer surface of the connecting frame 208 is slidably connected to the outer surface of the outer shell 1, and the outer surface of the connecting frame 208 is fixedly connected to the wind speed sensor 207. The wind speed sensor 207 is used to facilitate the detection of whether there is airflow passing under the sealing brush, so as to facilitate the detection of the airtightness of the sealing brush.

[0026] It is worth mentioning that when the first electric telescopic rod 210 is started, the output end of the first electric telescopic rod 210 drives the sliding frame 209 to slide on the inner wall of the shell 1, and the sliding frame 209 slides to drive the connecting frame 208 and the second electric telescopic rod 212 to slide synchronously, and the sliding of the second electric telescopic rod 212 drives the detection frame 203 and the detection plate 206 to slide, and then the second electric telescopic rod 212 is started, and the output end of the second electric telescopic rod 212 drives the detection frame 203 and the detection plate 206 to move downward, so as to facilitate pressure on the brush filaments of the sealing brush. At the same time, the connecting frame 208 drives the wind speed sensor 207 to slide toward the outer surface of the shell 1, and then the fan 201 is started. The fan 201 generates an air flow that blows into the wind gathering cover 202, and then blows to the outer surface of the brush filaments through the bellows 204 and the fixed frame 205, thereby facilitating the detection of the sealing of the brush filaments.

[0027] In order to facilitate the clamping of sealing brushes of different models, the clamping mechanism 3 includes a limiting frame 304 slidably connected to the inner wall of the shell 1, and the inner surface of the limiting frame 304 is rotatably connected to multiple groups of driven wheels 301 and a group of driving wheels 302. The outer surface of the limiting frame 304 is fixedly connected to the motor 303, and the output shaft of the motor 303 passes through the outer surface of the limiting frame 304 and is fixedly connected to the outer surface of the driving wheel 302.

The outer surface of the driven wheel 301 is rotatably connected to the inner wall of the shell 1, and the inner wall of the shell 1 is fixedly connected to the third electric telescopic rod 305, and the output end of the third electric telescopic rod 305 is fixedly connected to the upper surface of the limiting frame 304. By starting the third electric telescopic rod 305, it is convenient to clamp the outer surfaces of sealing brushes of different thicknesses.

[0028] It is worth mentioning that the sealing brush is placed between the driven wheel 301 and the driving wheel 302, and then the third electric telescopic rod 305 is started. The output end of the third electric telescopic rod 305 drives the limiting frame 304 to move downward along the inner wall of the shell 1, so that the outer surface of the driving wheel 302 clamps the outer surface of the sealing brush. Then, the motor 303 is started, and the output shaft of the motor 303 drives the driving wheel 302 to rotate. The rotation of the driving wheel 302 drives the sealing brush to slide on the outer surface of the driven wheel 301, thereby facilitating the adjustment of the detection position of the sealing brush.

[0029] Working principle: By placing the sealing brush between the driven wheel 301 and the driving wheel 302, and then starting the third electric telescopic rod 305, the output end of the third electric telescopic rod 305 drives the limiting frame 304 to move downward along the inner wall of the shell 1, so that the outer surface of the driving wheel 302 clamps the outer surface of the sealing brush, and then starting the motor 303, the output shaft of the motor 303 drives the driving wheel 302 to rotate, and the rotation of the driving wheel 302 drives the sealing brush to slide on the outer surface of the driven wheel 301, thereby facilitating the adjustment of the detection position of the sealing brush, and then starting the first electric telescopic rod 210, the output end of the first electric telescopic rod 210 drives the sliding frame 209 to slide on the inner wall of the shell 1, and the sliding frame 209 slides to drive the connecting frame 208 and the second electric telescopic rod 212 to slide synchronously The second electric telescopic rod 212 slides to drive the detection frame 203 and the detection plate 206 to slide, and then the second electric telescopic rod 212 is started. The output end of the second electric telescopic rod 212 drives the detection frame 203 and the detection plate 206 to move downward, so as to apply pressure to the bristles of the sealing brush. The pressure sensor 211 fixed in the detection frame 203 is convenient for detecting the pressure on the brush filaments, and the sliding frame 209 slides to facilitate the detection of brush filaments of different lengths. At the same time, the connecting frame 208 drives the wind speed sensor 207 to slide toward the outer surface of the shell 1, and then the fan 201 is started. The fan 201 generates an air flow that blows into the wind gathering cover 202, and then blows to the outer surface of the brush filament through the bellows 204 and the fixed frame 205, thereby facilitating the detection of the sealing of the brush filament.
