Description

Technical Field

[0001] This utility model relates to the field of side rubber strip support structure for floor scrubbers, and more particularly to a side rubber strip support structure for floor scrubbers. Background Technology

[0002] In existing side-mounted rubber strip support structures, the rubber strip is rigidly fixed to the edge of the floor scrubber's base shell by wrapping around it, forming a barrier around the scrubbing turntable. Due to the lack of dynamic adjustment, when the equipment encounters raised obstacles or performs turning maneuvers, the rubber strip cannot adaptively adjust its height, causing deformation due to lateral compression during turns. This continuous pressure not only creates structural gaps at the rubber edge, reducing wiping performance during turns, but also accelerates abnormal wear of the rubber strip, creating a vicious cycle of decreasing wiping efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a side rubber strip support structure for a floor scrubber, which solves the problem that the existing floor scrubber rubber strip structure cannot adapt to dynamic lifting and lowering adjustments, resulting in poor water scraping effect when turning and increased rubber strip wear.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A side strip support structure for a floor scrubber includes a main board and a brush plate disposed on the bottom surface of the main board. Two opposing strip support assemblies are provided on both sides of the main board, and the brush plate is located between the two strip support assemblies.

[0006] The adhesive strip support assembly includes a horizontal flip support, a floating support, and an adhesive strip seat. The horizontal flip support is connected to the main board via a horizontal rotating joint, the floating support is connected to the horizontal flip support via a vertical rotating joint, and the adhesive strip seat is fixed to the floating support and is equipped with a side adhesive strip.

[0007] The horizontal flip bracket has a closed posture and an unfolded posture: when closed, it is located directly above the motherboard, with the side rubber strips surrounding the side of the motherboard; when unfolded, it opens the side of the motherboard. The floating bracket maintains the tendency to press the top surface of the horizontal flip bracket with elastic elements.

[0008] Preferably, one end of the horizontal flip bracket is rotatably connected to a first rotating shaft. The first rotating shaft is arranged longitudinally and fixed on the main board. The horizontal flip bracket has a side opening on the inner side away from the first rotating shaft. When the horizontal flip bracket is in a closed position, a first screw is fixed on the top surface of the main board opposite the side opening. A first locking knob is threaded to the upper end of the first screw. The first locking knob abuts against the horizontal flip bracket, positioning it on the main board and locking its closed position. A connecting groove is provided at the end of the adhesive strip seat near the first rotating shaft, and the first rotating shaft passes through the connecting groove.

[0009] Preferably, one end of the floating support is fixed with a second rotating shaft, which is arranged laterally and rotatably connected between two side connecting plates on the top surface of the horizontal flipping support.

[0010] Preferably, the elastic element includes a second screw fixed to the top surface of the horizontally rotating bracket. The second screw passes through a through hole opened on the floating bracket. The diameter of the through hole is much larger than the outer diameter of the second screw to ensure that the floating bracket can smoothly rotate around the second pivot and extend above the floating bracket. The upper end of the second screw is threadedly connected to a second clamping knob. A spring is also sleeved on the upper end of the second screw. The upper end of the spring abuts against the bottom of the second clamping knob, and the lower end of the spring abuts against the floating bracket, so that the floating bracket abuts against the top surface of the horizontally rotating bracket.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. The floating bracket of this utility model realizes the up-and-down flip adjustment function through the elastic support structure of spring pretension, so that the side rubber strip can adapt to the height change when encountering a turn, avoiding the deformation of the side rubber strip under single-point pressure, which not only reduces abnormal wear of the side rubber strip, but also maintains the stable adhesion of the side rubber strip to the ground, significantly improving the wiping effect under curves and complex road conditions.

[0013] 2. The horizontal flip bracket of this utility model realizes the opening and closing switching through the rotating shaft mechanism. When unfolded, it frees up operating space on both sides of the motherboard, which is convenient for brush plate disassembly and maintenance. With the quick locking design of the clamping knob, the bracket state can be switched without tools, which greatly simplifies the daily maintenance process. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 6 This embodiment provides a side strip support structure for a floor scrubber, including a main board 1. Two brush discs 2 are rotatably mounted on the bottom surface of the main board 1. Horizontal flip brackets 3 are mounted on both sides of the main board 1, and the two horizontal flip brackets 3 are arranged opposite to each other. One end of each horizontal flip bracket 3 is rotatably connected to a first rotating shaft 4. The first rotating shaft 4 is arranged longitudinally and fixed on the main board 1. A side opening 301 is opened on the inner side of the horizontal flip bracket 3 away from the end of the first rotating shaft 4. A first screw 5 is fixed on the top surface of the main board 1. When the horizontal flip bracket 3 is in a closed position, the first screw 5 is located inside the side opening 301. The upper end of the first screw 5 is threaded with a first clamping knob 6. The first clamping knob 6 abuts against the horizontal flip bracket 3 and positions it on the main board 1, locking it in a closed position. Rotating the first clamping knob 6 moves it upward along the first screw 5, releasing the clamping of the horizontal flip bracket 3. Then, the horizontal flip bracket 3 can be flipped to the side of the main board 1 and flipped again to the top of the main board 1. After the side opening 301 is fitted over the outside of the first screw 5, rotating the first clamping knob 6 causes it to descend and clamp the horizontal flip bracket 3, lowering and locking it above the main board 1.

[0023] Two opposing side connecting plates 7 are fixed to the top surface of the horizontally flipping bracket 3. A second rotating shaft 8 is rotatably mounted between the two side connecting plates 7. A floating bracket 9 is fixed to the outer wall of the second rotating shaft 8. The floating bracket 9 extends away from the first rotating shaft 4. The end of the floating bracket 9 away from the first rotating shaft 4 is fixed to the connecting ear 1001 at the upper end of the adhesive strip holder 10. The connecting ear 1001 extends towards the side of the main board 1, and bends downward after passing the top surface of the main board 1. The adhesive strip holder 10 surrounds the brush plate 2 on the side of the main board 1. One end away from the second rotating shaft 8 bends past the main board 1 toward the front center of the main board 1 to form an inclined part 1002. The inclined part 1002 surrounds the main board 1 on the front side. The side adhesive strip 11 is attached and fixed to the outer wall of the adhesive strip seat 10, and the bottom surface of the side adhesive strip 11 is lower than the bottom surface of the brush plate 2. In this structural arrangement, the floating bracket 9 connects the adhesive strip seat 10 and the side adhesive strip 11, so that the side adhesive strip 11 has a movable space that can be raised and lowered. The side adhesive strip 11 can be rotated up and down around the axis of the second rotating shaft 8 on the floating bracket 9.

[0024] However, relying solely on the connecting ear 1001 to support and connect the adhesive strip seat 10 results in instability in the entire structure. Therefore, a connecting groove 1003 is provided at the end of the adhesive strip seat 10 near the first rotating shaft 4. The first rotating shaft 4 passes through the connecting groove 1003. However, the length of the connecting groove 1003 in the extension direction of the side adhesive strip 11 is much larger than the outer diameter of the first rotating shaft 4. But the length of the connecting groove 1003 in the direction perpendicular to the extension direction of the side adhesive strip 11 is slightly larger than the outer diameter of the first rotating shaft 4. This ensures that when the floating bracket 9 flips, the first rotating shaft 4 will not be hindered from moving by the connecting groove 1003. However, the movement of the side adhesive strip seat 10 away from the motherboard 1 is restricted due to the presence of the first rotating shaft 4 and the connecting groove 1003, thus improving the stability of the connection of the adhesive strip seat 10.

[0025] To ensure that the side rubber strip 11 has a force to press against the bottom surface, a second screw 12 is fixed on the top surface of the horizontal flip bracket 3. The second screw 12 extends through the through hole 901 opened on the floating bracket 9 to the top of the floating bracket 9. The diameter of the through hole 901 is much larger than the outer diameter of the second screw 12. The upper end of the second screw 12 is threadedly connected to a second clamping knob 13. A spring 14 is also sleeved on the upper end of the second screw 12. The upper end of the spring 14 abuts against the bottom of the second clamping knob 13, and the lower end of the spring 14 presses against the floating bracket 9, so that the floating bracket 9 is pressed against the top surface of the horizontal flip bracket 3. In this way, the spring 14 can be used to make the floating bracket 9 always have a downward flipping tendency. When the side rubber strip 11 contacts the ground, it can always stay in contact with the ground. When it encounters a raised obstacle or turns, it can overcome the elastic force of the spring 14 and flip upward instead of being squeezed, deformed and twisted. This ensures the wiping performance under working conditions such as turning, reduces the wear of the side rubber strip 11, extends its service life, and further guarantees the wiping performance.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
