DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a lockable universal joint handle of a floor scrubber.

[0034] Reference Figure 1 and Figure 2 A lockable universal joint handle for a floor scrubber comprises a mounting base 1, which can be mounted on a main body of the floor scrubber. Specifically, the mounting base 1 can be mounted on the top of the main body of the floor scrubber. A flip base 2 is rotatably connected to the mounting base 1, and a rotating handle body 3 is rotatably connected to the flip base 2. The rotation axis between the mounting base 1 and the flip base 2 is perpendicular to the rotation axis between the flip base 2 and the rotating handle body 3. When the mounting base 1 is mounted on the main body of the floor scrubber, the rotation axis between the mounting base 1 and the flip base 2 is parallel to the ground. A locking assembly for locking the flip base 2 is provided on the rotating handle body 3. The locking assembly is plugged into the flip base 2. The rotating handle body 3 extends in a straight direction. A grip is provided at one end of the rotating handle body 3 away from the flip base 2 (existing technology, not shown in the figure).

[0035] When the washing machine moves in a straight line, the locking assembly is locked with the flip seat 2, and the connection points between the flip seat 2 and the rotating handle body 3, the flip seat 2 and the rotating handle body 3 are arranged in a straight line. The staff only needs to hold the handle or the rotating handle body 3 to follow the washing machine to move forward for cleaning. The rotating handle body 3 can be rotated according to the height change of the staff's holding hand, so as to facilitate the staff's operation. When the washing machine needs to be turned, the locking assembly and the flip seat 2 can be unlocked. In this state, the rotating handle body 3 and the flip seat 2 can be rotated, which can make the turning The movable handle body 3 is rotated in the direction in which the floor scrubber is to be turned, and then the locking assembly can be locked with the flip seat 2 again, so that the connection point between the flip seat 2 and the rotating handle body 3, the flip seat 2 and the rotating handle body 3 are arranged in an angled line. Therefore, when the staff applies a turning thrust to the rotating handle body 3, the extension direction of the rotating handle body 3 can be made closer to the force application direction, reducing the force loss, making it easier for the floor scrubber to turn and achieving a labor-saving effect, so that the floor scrubber can meet the use requirements of steering convenience and straight-line control stability at the same time, and the operation convenience of the floor scrubber can be improved.

[0036] The locking assembly includes a connecting block 31, a movable plug-in 32 and a spring-loaded piece 33. The connecting block 31 is mounted on the rotating handle body 3 by bolts. An internal cavity is provided in the rotating handle body 3. The movable plug-in 32 is located inside the rotating handle body 3. The movable plug-in 32 is in the shape of a straight rod. The extending direction of the movable plug-in 32 is consistent with the extending direction of the rotating handle body 3. The movable plug-in 32 is slidably connected to the connecting block 31. The movable plug-in 32 passes through the connecting block 31. The sliding direction of the movable plug-in 32 is consistent with the extending direction of the movable plug-in 32. The spring-loaded piece 33 is a compression spring. One end of the spring-loaded piece 33 is connected to the connecting block 31 and the other end abuts against the outer side of the movable plug-in 32. One end of the movable plug-in 32 is plugged into the flip seat 2. A pull rope (not shown in the figure) is provided at the end of the movable plug-in 32 away from the flip seat 2.

[0037] When the rotating handle body 3 and the flip seat 2 need to rotate, the movable plug-in 32 can be pulled by a pull rope to separate the movable plug-in 32 from the flip seat 2, so that the rotating handle body 3 can be rotated. After the rotation is completed, the pressure spring 33 applies a thrust to the movable plug-in 32, forcing the movable plug-in 32 to be plugged into the flip seat 2, thereby completing the locking again.

[0038] A connecting plate 21 is fixedly connected to the flip seat 2, and a steering shaft 22 is rotatably connected to the side wall of the connecting plate 21. The rotation axis between the mounting seat 1 and the flip seat 2 is perpendicular to the extension direction of the steering shaft 22. The rotating handle body 3 is rotatably connected to the steering shaft 22, and the movable plug-in 32 is slidably connected to the steering shaft 22, and the movable plug-in 32 passes through the steering shaft 22.

[0039] The rotation axis of the rotating handle body 3 coincides with the rotation axis of the movable plug-in 32. When unlocking or locking is required, the movable plug-in 32 moves under the action of the pull rope or the pressure spring 33 and can slide on the steering shaft 22. When steering is required, the rotating handle body 3 can be rotated around the steering shaft 22. The steering shaft 22 provides good and stable support for the rotation of the rotating handle body 3.

[0040] An insertion hole 23 for inserting the mobile plug-in 32 is provided on one side of the flip seat 2 close to the rotating handle body 3 . The size of the insertion hole 23 matches the size of the mobile plug-in 32 , and the insertion holes 23 are distributed in a circle along the steering shaft 22 .

[0041] When steering is required, pull the movable plug-in 32 out of the insertion hole 23, rotate the rotating handle 3, and after the steering is completed, align the movable plug-in 32 with the insertion hole 23 at the corresponding position. Under the elastic force of the spring-loaded part 33, the movable plug-in 32 is inserted into the insertion hole 23, thereby completing further locking.

[0042] Reference Figure 2 and Figure 3A blocking piece 34 is detachably installed on the outer side of the movable plug-in 32, and an opening is provided on one side of the blocking piece 34. An annular clamping groove is provided on the outer side of the movable plug-in 32. The blocking piece 34 is clamped with the annular clamping groove of the movable plug-in 32, and one end of the pressure spring 33 away from the connecting block 31 abuts against the side of the blocking piece 34 close to the connecting block 31.

[0043] After the mobile plug-in 32 is separated from the insertion hole 23, the blocking piece 34 and the connecting block 31 compress the spring-loaded part 33. After the turning is completed, the spring-loaded part 33 applies a thrust to the blocking piece 34, so that the mobile plug-in 32 moves and is inserted into the insertion hole 23 to complete the locking. The blocking piece 34 is easy to disassemble and assemble and is easy to replace.

[0044] Reference Figure 2 and Figure 4 , rotating blocks 24 are symmetrically arranged on the opposite sides of the flip seat 2, and there are two rotating blocks 24. The two rotating blocks 24 are arranged along the extension direction of the rotation axis of the flip seat 2 and the mounting seat 1. The mounting seat 1 is rotatably connected with the rotating blocks 24. Damping clamps are arranged on the rotating blocks 24. The damping clamps are arranged circumferentially on the rotating blocks 24. A friction plate 11 is installed on the mounting seat 1. The friction plate 11 is provided with a clamping hole 12 for partial insertion of the damping clamp. The clamping holes 12 are arranged circumferentially around the rotation axis of the flip seat 2 and the mounting seat 1.

[0045] When the floor scrubber moves in a straight line, the staff can make the flip seat 2 and the mounting seat 1 rotate relative to each other, and the damping clamp and the clamp hole 12 can buffer and decelerate the flip seat 2 to improve the stability of the control.

[0046] The damping card includes a pop-up member 25 and a stop ball 26. The pop-up member 25 is installed on the inner wall of the end of the rotating block 24. The pop-up member 25 is a spring. The stop ball 26 is arranged at the end of the pop-up member 25. The end of the stop ball 26 away from the pop-up member 25 is inserted into the card hole 12. The volume of the stop ball 26 inserted into the card hole 12 does not exceed one third of the total volume of the stop ball 26. In this embodiment, the volume of the stop ball 26 inserted into the card hole 12 accounts for one third of the total volume of the stop ball 26.

[0047] When the flip seat 2 and the mounting seat 1 rotate, the stop ball 26 can be disengaged from the hole 12, and then inserted into the next hole 12 under the elastic force of the pop-up member 25, and then the process is repeated. During this process, the friction resistance of the rotation can be adjusted, and the tightness of the swing of the rotating handle body 3 can be adjusted.

[0048] A press block 13 is provided on the mounting seat 1, and the friction plate 11 is plugged into the press block 13, and the friction plate 11 is plugged into the mounting seat 1. A disassembly component 14 is provided on the press block 13, and the disassembly component 14 is a bolt. The threaded portion of the disassembly component 14 passes through the press block 13, and the threaded portion of the disassembly component 14 is threadedly connected to the mounting seat 1.

[0049] The mounting seat 1 and the press block 13 can clamp and fix the friction plate 11 to improve the stability of the overall structure, and the disassembly member 14 can improve the convenience of disassembly and assembly of the press block 13 and the friction plate 11.

[0050] The implementation principle of a lockable universal joint handle for a floor scrubber in an embodiment of the present application is as follows: when the floor scrubber moves in a straight line, the locking assembly is locked with the flip seat 2, and the staff only needs to hold the handle or the rotating handle body 3 by hand to follow the floor scrubber forward for cleaning. The rotating handle body 3 can rotate according to the change in the height of the staff's holding hand. When the floor scrubber needs to be turned, the locking assembly and the flip seat 2 can be unlocked, and the rotating handle body 3 and the flip seat 2 can be rotated to rotate the rotating handle body 3 in the direction in which the floor scrubber is to turn, and then the locking assembly and the flip seat 2 can be locked again. When turning, the extension direction of the rotating handle body 3 can be close to the force application direction, so that the floor scrubber can be easily turned, so that the floor scrubber can meet the use requirements of steering convenience and linear control stability at the same time, and the operation convenience of the floor scrubber can be improved.
