[0023] like Figures 1-4 As shown, an industrial brush quick-release expansion sleeve includes an expansion sleeve body 1. Assembly slots 2 are symmetrically formed on the side walls of the expansion sleeve body 1. A height adjustment mechanism is installed within the assembly slots 2, including a positioning screw 4. A support square plate 3 is slidably inserted onto the positioning screw 4, and a positioning nut 5 is screwed onto the positioning screw 4. The assembly slots 2 are arranged in a square structure. Arc-shaped protective boxes 6 are symmetrically installed on the support square plate 3. The arc-shaped protective boxes 6 have a semi-circular structure. The arc-shaped protective boxes 6 located on the upper and lower sides of the expansion sleeve body 1 are combined to form a complete ring structure, which facilitates the all-around protection of the outer side of the expansion sleeve body 1 by assembling the arc-shaped protective boxes 6 into a sleeve shape.

[0024] Replacement slots 9 are symmetrically provided on both sides of the positioning screw 4 on the side wall of the assembly slot 2, and height support columns 10 are slidably inserted in the replacement slots 9. The height support columns 10 can be easily replaced by sliding, thereby changing the height of the support square plate 3 in the assembly slot 2, and thus facilitating the adjustment of the height of the arc-shaped protective box 6 on the expansion sleeve body 1.

[0025] An air-blowing mechanism is provided between the side walls of two adjacent arc-shaped protective boxes 6. The air-blowing mechanism includes a connecting air box 7. The two sides of the connecting air box 7 are respectively fixedly installed on the two arc-shaped protective boxes 6, and the connecting air box 7 is connected to the arc-shaped protective boxes 6. An air blower 8 is fixedly installed on the side wall of the connecting air box 7, and the air blower 8 is connected to the connecting air box 7. The air blower 8 can inject external air into the connecting air box 7, thereby forming an airflow to clean and maintain the end face of the expansion sleeve body 1.

[0026] The arc-shaped protective box 6 is equipped with an air outlet mechanism, which includes a protective mesh cover 11. An air outlet 12 is opened on the inner ring side wall of the arc-shaped protective box 6. The protective mesh cover 11 is fixedly installed inside the air outlet 12. The protective mesh cover 11 can prevent debris from entering the arc-shaped protective box 6, and the airflow formed inside the arc-shaped protective box 6 can be discharged through the air outlet 12.

[0027] In summary: After assembling the industrial brush using the expansion sleeve, the operator can insert the corresponding height support column 10 into the replacement slot 9 of the assembly slot 2, then slide the support square plate 3 into the positioning screw 4, and then fix it using the positioning nut 5. In this way, the arc-shaped protective box 6 on the upper and lower support square plates 3 can combine with the expansion sleeve body 1 to form a protective tubular structure, thereby protecting the expansion sleeve body 1 and reducing the probability of dirt sticking to the expansion sleeve body 1. At the same time, by starting the blower 8 on the connecting air box 7, the blower 8 can inject external airflow into the arc-shaped protective box 6, and then export the gas through the air outlet 12, thereby cleaning the side walls at both ends of the expansion sleeve body 1. This can effectively reduce the amount of dirt on the expansion sleeve body 1, thereby reducing the wear rate of the expansion sleeve during the transmission process.

[0028] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
