Description

Technical Field

[0001] The present application relates to a floor scrubber, and more particularly to a conveniently adjustable squeegee lifting mechanism. Background Art

[0002] There are two ways to raise or lower the squeegee of existing floor scrubbers: one is manual lifting, which uses a handle or a cable to raise or lower the squeegee manually; the other is to raise or lower the squeegee using an electric tool such as an electric push rod. For medium and large floor scrubbers, the first method not only increases the operator's workload, but also lacks certain convenience.

[0003] There are two ways to control the working pressure of the existing floor scrubber squeegee: the first is to rely on the weight of the squeegee itself, but there is a situation where the squeegee pressure is insufficient, resulting in a poor scraping effect; the second is to rely on the weight of the squeegee itself or add a counterweight, but the mechanism is heavy and the material cost is high. When working on a bumpy ground, the squeegee will jump up and down, affecting the water absorption effect.

[0004] In order to achieve the ideal water absorption effect, the squeegee of a floor scrubber needs to be adjusted in height left and right and in angle front and back, but most of the current products have problems with adjustment difficulty and poor stability. Utility Model Content

[0005] In order to improve the problem of difficult adjustment and poor stability of the existing squeegee for floor scrubbers when adjusting the left and right height and the front and rear inclination angle, the present application provides a conveniently adjustable squeegee lifting mechanism.

[0006] The present application provides a conveniently adjustable squeegee lifting mechanism, which adopts the following technical solution:

[0007] A conveniently adjustable squeegee lifting mechanism, comprising:

[0008] Frame,

[0009] A swing assembly, one end of which is rotatably connected to the frame;

[0010] A driving assembly, one end of which is rotatably connected to the frame, and the driving assembly is used to drive the swing assembly to swing;

[0011] A pressure component, wherein the pressure component is connected to the swing component, and one end of the pressure component is rotationally connected to the frame and the driving component respectively through a linkage component;

[0012] A height adjustment component, wherein the height adjustment component is mounted on the swing component, and one end of the height adjustment component is rotatably connected to the swing component, and the other end of the height adjustment component is in contact with the ground;

[0013] An elevation angle adjustment component, wherein the elevation angle adjustment component is mounted on the swing component, and one end of the elevation angle adjustment component is rotatably connected to the swing component;

[0014] A water suction rake is installed on the swing assembly, and one end of the water suction rake is hinged to the swing assembly; the elevation angle adjustment assembly is rotatably connected to one end of the water suction rake away from the hinge point.

[0015] By adopting the above technical solution, when the height of the water suction rake needs to be adjusted, the height adjustment component is rotated, and the height adjustment component pushes the swing component to move relative to the ground, the height of the swing component changes, and the pressure applied by the pressure component to the swing component increases or decreases; at the same time, the left and right heights of the water suction rake are reduced or increased. When the elevation angle between the water suction rake and the ground needs to be adjusted, the elevation adjustment component is rotated, and the elevation adjustment component moves relative to the swing component, and the elevation adjustment component drives the end of the water suction rake away from the hinge point to swing back and forth, thereby adjusting the elevation angle of the water suction rake. Operation process: The driving component drives the linkage component to rotate, the linkage component pushes the pressure component to slide, the pressure component drives the swing component to swing, and the swing component drives the water suction rake to swing until the water suction rake contacts the ground, the driving component stops working, and the floor washing operation can be carried out. The above scheme, by providing a height adjustment component capable of adjusting the left and right height of the water suction rake, an elevation adjustment component capable of adjusting the elevation angle between the water suction rake and the ground, and a pressure applying component for applying corresponding pressure to the water suction rake, can improve the problem of difficult adjustment and poor stability when the existing water suction squeegee of the floor scrubber needs to be adjusted in height left and right and in elevation front and back.

[0016] Optionally, the swing assembly includes:

[0017] A swing base plate, one end of which is rotatably connected to the frame, and the pressure assembly is connected to the swing base plate;

[0018] A first mounting plate, wherein at least two first mounting plates are provided, and at least one first mounting plate is mounted on each side of the swing base plate;

[0019] The height adjustment components are mounted on the first mounting plate, and at least one set of height adjustment components is arranged on each mounting plate;

[0020] A second mounting plate, the second mounting plate being mounted on an end of the swing base plate away from the rotation point;

[0021] The elevation angle adjustment assembly is rotatably connected to the second mounting plate, and one end of the water suction rake is hinged to the second mounting plate.

[0022] By adopting the above technical scheme, the driving component drives the linkage component to rotate, the linkage component drives one end of the pressure component to swing, the end of the pressure component connected to the swing base plate pushes the swing base plate to swing, the swing base plate drives the first mounting plate and the second mounting plate to swing, thereby driving the height adjustment component, the elevation adjustment component and the water suction rake to swing. By setting the linkage component, the pressure component, the swing base plate, the first mounting plate and the second mounting plate, a certain pressure can be applied to the water suction rake while maintaining stable swinging; the operator only needs to control the working state of the driving component to achieve stable lifting and lowering of the water suction rake, the structure is simple, the stability is high, and it is also easy to adjust.

[0023] Optionally, the pressure applying component includes:

[0024] A lifting component, one end of which is hinged to the linkage assembly, and the other end of which is passed through the swing base plate and is slidably connected to the swing arm base plate;

[0025] The lifting component has a limiting portion on one end away from the hinged end of the linkage assembly, and the limiting portion abuts against the surface of the swing base plate; the limiting portion is used to stabilize the connection between the lifting component and the swing base plate;

[0026] A first elastic component, wherein the first elastic component is sleeved on the lifting component, and one end of the first elastic component is in contact with the first mounting plate; the first elastic component is used to provide a reaction force for the swing base plate;

[0027] The first elastic component has elasticity.

[0028] By adopting the above technical scheme, when the driving component drives the water suction rake to rise and fall, one end of the lifting component swings under the action of the linkage component and pushes the first elastic component to rise and fall. The first elastic component drives the swing base plate to rise and fall. The reaction force or pressure exerted by the first elastic component on the swing base plate is indirectly transmitted to the water suction rake. The lifting component not only transmits the power of the driving component, but also guides the movement direction of the first elastic component so that it can stably exert a reaction force on the swing base plate. When the floor scrubber is operating and encounters a bumpy ground, since the first elastic component exerts a reaction force on the swing base plate and the first elastic component is elastic, the impact force generated by the bumpy ground is buffered or dispersed by the first elastic component, so that the water suction rake does not change with the change of the ground height, and will not jump up and down when encountering a bumpy ground, thereby maintaining a better water absorption effect.

[0029] Optionally, the height adjustment component includes:

[0030] A universal wheel, the universal wheel is mounted on the first mounting plate;

[0031] The universal wheel has a connecting portion, and the connecting portion is rotatably connected to the first mounting plate;

[0032] A fixing component is sleeved on the connecting portion and threadedly connected to the connecting portion; one end of the fixing component abuts against the surface of the first mounting plate.

[0033] By adopting the above technical solution, when the height of the water suction rake needs to be adjusted, loosen the fixing component to keep it away from the first mounting plate, and then turn the universal wheel to adjust the height between the shaft core of the universal wheel and the end face of the swing base plate, so that the height between the water suction rake and the ground changes. After the water suction rake is adjusted to an appropriate height, tighten the fixing component, and the fixing component and the first mounting plate are pressed tightly to lock the universal wheel. The pressure applied by the first elastic component to the water suction rake is generally overpressure, and the excess pressure needs to be borne by a structure that can move with the floor scrubber. Therefore, by setting the universal wheel, on the one hand, the excess pressure can be borne, and on the other hand, by turning the universal wheel, the height between the universal wheel and the end face of the swing base plate can be adjusted, so that the left and right height of the water suction rake can be changed, and the height of the water suction rake can be adjusted. This method is not only convenient to adjust, but also relatively simple in structure.

[0034] Optionally, the elevation angle adjustment component includes:

[0035] An elevation component, one end of which is passed through the second mounting plate and is threadedly connected to the second mounting plate;

[0036] One end of the elevation component abuts against the water suction rake;

[0037] A locking component is sleeved on the elevation component and is threadedly connected to the elevation component.

[0038] By adopting the above technical solution, the locking component is loosened to move it away from the second mounting plate, and the elevation component is rotated. The elevation component pushes the end of the water suction rake away from the hinge point to swing, and the elevation angle between the water suction rake and the ground changes. After the adjustment is completed, the locking component is tightened to quickly adjust the angle of the water suction rake.

[0039] Optionally, the linkage component includes:

[0040] A lifting frame, the lifting frame is rotatably mounted on the vehicle frame;

[0041] The lifting frame is provided with a first hinge part and a second hinge part, and the angle between the first hinge part and the second hinge part is set at an angle of thirty to forty degrees around the rotation point of the lifting frame;

[0042] The first hinged portion is hinged to the lifting component;

[0043] One end of the driving assembly is hinged to the second hinged portion.

[0044] By adopting the above technical solution, the angle between the first hinge part and the second hinge part is set at thirty to forty degrees, which can better transmit the force of the driving component to drive the swing base plate to swing, so that the water suction rake can be lifted and lowered stably; and the swing base plate can obtain a better swinging distance, so that the water suction rake can obtain a larger lifting distance.

[0045] Optionally, the water suction rake is connected to the second mounting plate via a buffer assembly, one end of the buffer assembly is passed through the second mounting plate and is threadedly connected to the second mounting plate;

[0046] One end of the buffer component is plugged into the water suction rake and is rotatably connected to the water suction rake.

[0047] By adopting the above technical solution, when the water suction rake encounters a raised ground or a stone, the buffer component can buffer the impact force and reduce the degree of damage to the water suction rake.

[0048] Optionally, the buffer component includes:

[0049] A plug-in component, one end of which is passed through the second mounting plate and is threadedly connected to the second mounting plate;

[0050] One end of the plug-in component is rotatably connected to the water suction rake;

[0051] A pressure regulating component, wherein the pressure regulating component is sleeved on the plug-in component and is threadedly connected to the plug-in component;

[0052] A second elastic component, wherein the second elastic component is sleeved on the plug-in component, and one end of the second elastic component abuts against the surface of the second mounting plate, and the other end abuts against the pressure regulating component;

[0053] The second elastic component is elastic.

[0054] By adopting the above technical solution, when it is necessary to adjust the buffering force of the buffer component on the water suction rake or the downward pressure applied to the water suction rake, the pressure regulating component is rotated to adjust the deformation of the second elastic component, thereby changing the buffering force of the buffer component on the water suction rake or the downward pressure applied to the water suction rake; at the same time, the second elastic component is provided to further apply pressure to the water suction rake and provide corresponding buffer space. When the water suction rake encounters a raised ground or stone, the second elastic component can buffer the impact force and reduce the degree of damage to the water suction rake.

[0055] Optionally, a radial spherical bearing is provided on the swing base plate, and one end of the lifting component away from the hinge point is penetrated by the radial spherical bearing and is slidably connected to the radial spherical bearing.

[0056] By adopting the above technical solution, a radial spherical bearing is set to bear the radial load generated by the lifting component during the sliding process, and to support the stable swing of the swing base plate, thereby reducing the shaking problem during the lifting and lowering of the water suction rake.

[0057] In summary, this application has the following beneficial effects:

[0058] 1. By providing a height adjustment component capable of adjusting the left and right height of the water suction rake, an elevation adjustment component capable of adjusting the elevation angle between the water suction rake and the ground, and a pressure component for applying corresponding pressure to the water suction rake, the problem of difficulty in adjustment and poor stability when the water suction squeegee of the existing floor scrubber is to be adjusted in height left and right and in elevation front and back can be improved.

[0059] 2. By setting up the linkage component, the pressure component, the swing base plate, the first mounting plate and the second mounting plate, a certain pressure can be applied to the water suction rake while maintaining stable swing; the operator only needs to control the working state of the driving component to achieve stable lifting and lowering of the water suction rake. The structure is simple, stable and easy to adjust.

[0060] 3. The lifting component not only transmits the power of the driving component, but also guides the movement direction of the first elastic component, so that it can stably apply a reaction force to the swing base plate; when the floor scrubber is operating, it encounters a bumpy ground. Since the first elastic component applies a reaction force to the swing base plate, and the first elastic component is elastic, the impact force generated by the bumpy ground is buffered or dispersed by the first elastic component, so that the water suction rake does not change with the change of the ground height, and does not jump up and down when encountering a bumpy ground, thereby maintaining a better water absorption effect.

[0061] 4. The pressure applied by the first elastic component to the water suction rake is generally overpressure, and the excess pressure needs to be borne by a structure that can move with the scrubber. Therefore, by setting a universal wheel, on the one hand, the excess pressure can be borne, and on the other hand, by rotating the universal wheel, the height between the universal wheel and the end face of the swing base plate can be adjusted to change the left and right height of the water suction rake, thereby realizing the adjustment of the height of the water suction rake. This method is not only convenient to adjust, but also relatively simple in structure.

[0062] 5. By setting the elevation component and the locking component, loosen the locking component to move it away from the second mounting plate, rotate the elevation component, and the elevation component pushes the end of the water suction rake away from the hinge point to swing, and the elevation angle between the water suction rake and the ground changes. After the adjustment is completed, tighten the locking component to quickly adjust the angle of the water suction rake. BRIEF DESCRIPTION OF THE DRAWINGS

[0101] The working principle of a conveniently adjustable squeegee lifting mechanism of the present application is as follows:

[0102] The initial state is: the driving assembly 3 is retracted to the shortest position, the lifting component 41 lifts the swing assembly 2 to a high position, the limiting portion 410 of the lifting component 41 contacts the swing base plate 21, and the squeegee is off the ground.

[0103] When the driving assembly 3 is working, the electric push rod extends and the linkage assembly 8 swings, that is, the second hinged part 82 drives the lifting frame to swing downward (counterclockwise), and the first hinged part 81 drives the lifting component 41, the swing base plate 21, the first mounting plate 22, the second mounting plate 23 and the squeegee to move downward synchronously.

[0104] When the universal wheel 51 contacts the ground, the swing base plate 21, the first mounting plate 22, the second mounting plate 23 and the water suction rake 7 stop moving; the electric push rod continues to extend, the lifting component 41 continues to descend, the limiting portion 410 of the lifting component 41 is out of contact with the swing base plate 21, the first elastic component 42 is compressed, and the increased pressure reacts on the second mounting plate 23.

[0105] The electric push rod stops after being extended to the longest position. At this time, the pressure generated by the first elastic component 42 acts indirectly on the squeegee to ensure that the squeegee has a constant pressure and works smoothly.

[0106] When the electric push rod is shortened, the lifting frame swings upward (clockwise), and the lifting component 41 starts to move upward; when the limiting portion 410 of the lifting component 41 contacts the lower surface of the swing base plate 21, the lifting component 41 lifts the swing base plate 21, the first mounting plate 22, the second mounting plate 23 and the squeegee; the electric push rod stops after being shortened to the shortest, at which time the squeegee 7 leaves the ground and the drive assembly 3 returns to its initial state.

[0107] Adjust the height of the water suction rake 7: By rotating the universal wheel 51, the left and right height of the first mounting plate 22 can be changed, thereby adjusting the left and right height of the water suction rake 7. After the adjustment, tighten the M20 nut.

[0108] Adjust the elevation angle of the water suction rake 7: through the length of the elevation angle bolt, that is, loosen the M8 nut to make it away from the second mounting plate 23, turn the elevation angle bolt, the elevation angle bolt pushes the end of the water suction rake 7 away from the hinge point to swing back and forth in a small range, thereby realizing the adjustment of the front and rear elevation angle of the water suction rake 7.
