Description

Technical Field

[0001] This utility model relates to a quick-assembly structure for a floor scrubber brush disc. Background Technology

[0002] In the field of cleaning equipment, floor scrubbers, as efficient and convenient floor cleaning tools, are widely used in various commercial and industrial settings. By installing brushes, floor scrubbers can perform functions such as brushing and scrubbing, greatly improving the efficiency and quality of floor cleaning. However, in existing technology, floor scrubbers with brushes generally face a pressing problem during use and maintenance: the disassembly and assembly process of the brushes is too cumbersome.

[0003] Specifically, traditional floor scrubber brush installation structures are often complex, requiring operators to use specialized tools and go through multiple steps to disassemble and assemble the brush. This not only increases the operator's workload and reduces work efficiency, but also causes considerable inconvenience when frequently changing brushes or performing routine maintenance. Furthermore, the complex disassembly and assembly process can potentially damage the brush or other components of the floor scrubber, increasing maintenance costs and downtime. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide a quick-installation structure for the brush disc of a floor scrubber.

[0005] The technical solution of this utility model is: a quick-release structure for a floor scrubber brush disc, including a main unit and a brush disc. The lower end of the main unit has a bushing, and the lower end of the bushing is covered with a sliding sleeve that slides vertically with the bushing. The lower end of the bushing is covered with a spring that extends vertically. A retaining ring is fixed at the lower end of the bushing. A convex ring is inside the sleeve, and the spring is stuck between the bottom of the convex ring and the top of the retaining ring. A sleeve for driving the sliding sleeve to move downward is covered with a sleeve. A base is fixed at the bottom of the sleeve. The lower end side wall of the bushing has at least two through holes that penetrate internally and externally. A steel ball is placed in each through hole. The convex ring blocks the steel ball. The top of the brush disc has a hexagonal rod, and the outer side of the hexagonal rod has an arc-shaped groove. The lower end of the bushing has a slot, and the hexagonal rod is inserted into the slot, and the steel ball is stuck into the arc-shaped groove.

[0006] Furthermore, the lower end of the sleeve has a first step, and the outer wall of the sliding sleeve has a second step, with the first step pressing on top of the second step.

[0007] Furthermore, after pulling the sleeve downwards, the sleeve causes the sliding sleeve to move downwards, separating the convex ring from the steel ball.

[0008] The advantages of the quick-installation structure for a floor scrubber brush provided by this utility model are as follows: When installing the brush, pull down the sleeve, and the sleeve will move the sliding sleeve downwards, separating the convex ring from the steel ball. At this time, the hexagonal rod can be inserted. After releasing, the spring will drive the sleeve and sliding sleeve to return to their original positions, and the convex ring will block the steel ball, so that the steel ball can be firmly inserted into the arc-shaped groove. When disassembling, pull down the sleeve, and then the hexagonal rod can be pulled out. Both disassembly and assembly are relatively convenient. Attached Figure Description

[0016] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0017] like Figure 1 — Figure 6As shown, a quick-release structure for a floor scrubber brush disc includes a main unit 1 and a brush disc 2. The lower end of the main unit 1 has a bushing 3. The lower end of the bushing 3 is covered by a sliding sleeve 4 that slides vertically with the bushing 3. The lower end of the bushing 3 is covered by a spring 5 that extends vertically. A retaining ring 6 is fixed at the lower end of the bushing 3. A protruding ring 42 is inside the sleeve 7. The spring 5 is locked between the bottom of the protruding ring 42 and the top of the retaining ring 6. The sliding sleeve 4 is covered by a sleeve 7 for driving the sliding sleeve 4 to move downward. A base 8 is fixed at the bottom of the sleeve 7. The lower side wall of the bushing 3 has at least two through holes 31 that are internally and externally connected. A steel ball 9 is placed in each through hole 31. The protruding ring 42 blocks the steel ball 9. The top of the brush disc 2 has a hexagonal rod 21. The outer side of the hexagonal rod 21 has an arc-shaped groove 211. The lower end of the bushing 3 has a slot 32. The hexagonal rod 21 is inserted into the slot 32, and the steel ball 9 is locked into the arc-shaped groove 211. The base 8 has a through hole 81 that runs vertically through the hexagonal rod 21. In a preferred embodiment of this utility model, there are two through holes 31, which are located on the left and right sides of the lower end of the bushing 3, respectively.

[0018] like Figure 5 , Figure 6 As shown, the lower end of the sleeve 7 has a first step 71, and the outer wall of the sliding sleeve 4 has a second step 41. The first step 71 presses against the top of the second step 41. Therefore, when the sleeve 7 is pulled down, the sleeve 7 can drive the sliding sleeve 4 to move downward.

[0019] like Figure 3 As shown, after pulling down the sleeve 7, the sleeve 7 drives the sliding sleeve 4 to move downward, and the convex ring 42 separates from the steel ball 9.

[0020] When installing the brush plate 2, pull down the sleeve 7. The sleeve 7 moves the sliding sleeve 4 downward, and the convex ring 42 separates from the steel ball 9. At this time, the hexagonal rod 21 can be inserted. After releasing, the spring 5 drives the sleeve 7 and the sliding sleeve 4 to return to their original positions. The convex ring 42 blocks the steel ball 9, so that the steel ball 9 can be firmly inserted into the arc-shaped groove 211. When disassembling, pull down the sleeve 7, and then the hexagonal rod 21 can be pulled out. Disassembly and assembly are both relatively convenient.

[0021] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
