Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically to the field of floor scrubber technology of a coupling mechanism and its application. Background Technology

[0002] As an effective tool for cleaning hard floors, floor scrubbers are increasingly widely used in daily life due to their environmental protection, energy saving and high efficiency, and have shown a clear trend in various scenarios.

[0003] However, with the increasing popularity of floor scrubbers in home use, users have higher requirements for the ease of moving them in different scenarios. For example, there are more frequent situations in daily life where floor scrubbers need to be moved, such as going up and down stairs or getting in and out of cars. Existing designs involve moving the machine via a handle on a linkage, which requires a sufficiently rigid connection between the linkage and the machine body.

[0004] However, the connecting rods and main body of the floor scrubbers currently on the market are complex, heavy, have many parts, and have low reliability, making it difficult to meet the needs of flexibly moving the machine. Summary of the Invention

[0005] In response to the aforementioned needs, this application proposes a coupling mechanism and its application in a floor scrubber, aiming to overcome the shortcomings of the prior art as described above. By improving the coupling method between the connecting rod and the machine body, it is intended to reduce the overall weight, reduce assembly difficulty, and improve equipment reliability.

[0006] To achieve the above objectives, the present application adopts the following technical solution:

[0007] In a first aspect, this application provides a coupling mechanism, including a connecting rod connecting the body of a floor scrubber and a handle, and a handle disposed in the middle section of the connecting rod. The connecting rod has a groove at the handle, and the handle has a connecting rod cover that engages with the groove.

[0008] It also includes a connector that is vertically fitted to the sewage tank, the connector having a fastening groove at its upper end, and the connector being positioned directly below the connecting rod in its folded state;

[0009] It also includes a snap-fit ​​assembly disposed within the groove and locking the connecting rod with the snap-fit ​​groove.

[0010] In this way, by setting a buckle in the groove space inside the connecting rod and integrating the connecting rod cover and handle into one design, not only is the traditional complicated connection method simplified and the number of parts reduced, but the overall weight is also effectively reduced, and the convenience of carrying and handling is improved.

[0011] Meanwhile, the vertically fitted connectors to the wastewater tank and the locking grooves on the upper ends of the connectors further enhance the integration and compactness of the entire system. Placing the connectors directly below the folded rods reduces the space occupied when the equipment is not in use and effectively locks the rods, ensuring robustness and stability during operation.

[0012] In some possible implementations, the snap-fit ​​assembly includes a pin embedded in the groove and restricted in the forward and backward direction, wing-shaped snaps sequentially fitted onto the pin from front to back, and a spring that applies a restoring force in the locking direction.

[0013] In some possible implementations, the wing-shaped buckle has a locking part that engages with the buckle groove and a bushing part that sleeves the pin and drives the locking part.

[0014] In some possible implementations, a pressing portion is also included, which is disposed on at least one side of the bushing and extends to the outside of the connecting rod.

[0015] In some possible implementations, the latching part includes a hook portion that remains locked to the latching groove in the locked state, and a guide bevel portion that contacts the connector during the locking process to automatically lock the latching part.

[0016] In some possible implementations, pressure plates are also provided at both ends of the pin and to fix the pin.

[0017] In some possible implementations, the bottom of the connector is connected to the chassis, and the top is fastened to the sewage tank.

[0018] In some possible implementations, the connecting rod is provided with a quick-release mounting portion.

[0019] Secondly, this application also provides a floor scrubbing machine that uses the coupling mechanism described above. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0027] Please refer to Figure 1 This is a schematic diagram of a floor scrubber with its connecting rod 1 folded and engaged with the machine body 100, according to a coupling mechanism and its application described in this application. A wastewater tank 200 is located at the front end of the machine body 100. One end of the connecting rod is connected to the machine body 100, and the other end has a handle 300. During normal use, the machine is moved up and down stairs or onto a transport vehicle in this state. At this time, it is necessary to ensure a rigid connection between the connecting rod 1 and the machine body 100 to prevent it from falling off during transport. In some embodiments, the connecting rod 1 has a quick-release mounting part 11, which facilitates the removal and installation of the handle 300, further reducing the overall machine space and facilitating transport.

[0028] To address this, this application utilizes an innovative coupling structure to ensure its stability; please refer to [reference needed]. Figures 2 to 4 This application provides a coupling mechanism for achieving a rigid connection when the connecting rod 1 is folded into the body 100 and a release when the connecting rod 1 is unfolded, as described above. A handle 2 is provided in the middle section of the connecting rod 1, and a groove 12 is provided on the connecting rod 1 corresponding to the handle 2. The handle 2 also has a connecting rod cover 21 that engages with the groove 12. A snap-fit ​​assembly 3, serving as a sub-buckle, is then installed using the space within the groove 12.

[0029] Correspondingly, please refer to Figure 1 and Figure 2 The connector 4, which serves as the female buckle, is vertically mounted on the sewage tank 200. The upper end of the connector 4 has a buckle groove 41. The connector 4 is positioned directly below the connecting rod 1 in its folded state. When the connecting rod 1 is folded, the buckle assembly 3 locks into the buckle groove 41. Specifically, the bottom of the connector 4 is connected to the chassis 400, and the upper part is securely connected to the sewage tank 200 via screws through fixing holes 42.

[0030] The following is a detailed description of the snap-fit ​​component 3. Please refer to it. Figures 2 to 4The snap-fit ​​assembly 3 includes a pin 31 that is embedded in the groove 12 and restricts its forward and backward movement. At the same time, four mounting holes 121 are provided around the groove 12 of the connecting rod 1. After the front and rear ends of the pin 31 are pressed on by the pressure plate 122, the top of the pin 31 is flush with the mounting plane of the pressure plate 122. After the pressure plate 122 is pressed on, the pin 31 can be restricted to move up and down by fastening screws 123. Combined with the restriction of the forward and backward movement of the pin 31 by the contact surface of the groove 12, the pin 31 is fixed.

[0031] Furthermore, from front to back, the pin 31 is fitted with a wing-shaped buckle 32 and a spring 33. The spring 33 applies a restoring force in the locking direction. That is, when the spring 33 is in the reset and unfolded state, the buckle assembly 3 and the buckle groove 41 will lock.

[0032] Specifically, the wing-shaped buckle 32 has a locking part 321 that engages with the buckle groove 41 and a bushing part 322 that sleeves the shaft pin 31 and drives the locking part 321. That is, the bushing part 322 and the locking part 321 are fixedly connected, and the locking part 321 passes through the connecting rod 1 and engages with the buckle groove 41 downwards. At the same time, one end of the bushing part 322 can abut against the groove 12, and the other end abuts against the spring 33, pushing the spring 33 to compress, and at the same time, it is abutted against the groove 12 by the restoring force of the spring 33. As the force-receiving part that can compress the spring 33, at least one side of the bushing part 322 is provided with a pressing part 34 extending to the outside of the connecting rod 1. In this embodiment, there are two pressing parts 34, respectively provided on both sides.

[0033] Furthermore, the latching part 321 includes a hook part 3211 that remains locked to the latching groove 41 in the locked state, and a guide slope part 3212 that contacts the top of the connector 4 during the locking process, so that the latching part 321 automatically locks.

[0034] In practical use, when the connecting rod 1 is pressed down until the guide slope 3212 contacts the top of the connector 4, the slope will push the wing-shaped latch 32 backward, causing it to overcome the elastic force of the spring 33 and compress its length. At this time, the wing-shaped latch 32 of the connecting rod 1 continues to fall. After the connecting rod 1 is folded down to a horizontal state, the hook part 3211 at the bottom of the wing-shaped latch 32 will hook onto the latch groove 41. The elastic force of the spring 33 pushes the wing-shaped latch 32 to fit against the surface of the connector 4, thereby achieving the function of locking the connecting rod 1 and the connector 4, that is, the machine body 100. In this state, the floor scrubber can be lifted by the handle 2.

[0035] When unlocking is required, the wing-shaped latch 32 is pushed backward by the pressing part 34, so that the wing-shaped latch 32 overcomes the resistance of the spring 33, and the connecting rod 1 is disengaged from the connecting part 4 to achieve unlocking. At this time, the connecting rod 1 can be rotated upward to turn the connecting rod 1 into the working state.

[0036] In this way, by setting a buckle in the groove 12 space inside the connecting rod 1 and integrating the connecting rod cover 21 and the handle 2 into one unit, not only is the traditional complex connection method simplified and the number of parts reduced, but the overall weight is also effectively reduced, and the convenience of carrying and handling is improved.

[0037] Meanwhile, the vertically fitted connector 4 and the latching groove 41 on the upper end of the connector 4 further enhance the integration and compactness of the entire system. Placing the connector 4 directly below the connecting rod 1 in its folded state reduces the space occupied by the equipment when not in use and effectively locks the connecting rod 1, ensuring its robustness and stability during operation.

[0038] As stated above, this case protects a coupling mechanism and a floor scrubbing machine using it. All technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
