Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a crank structure and a cleaning machine. Background Art

[0002] Crank handles are commonly used in the field of mechanical equipment. Currently, the existing crank handles on the market are snap-on type, such as Figure 1 As shown, the connecting rod 13 and the rotating shaft 14 are usually connected by a plastic buckle, which mainly works by deforming the plastic buckle. That is, the user can rotate the crank with a force greater than the deformation of the buckle plastic. This solution has the following disadvantages:

[0003] The handle 11 and the rotating shaft 14 are always located on different sides of the connecting rod 13. When the crank is not needed, the handle 11 and the rotating shaft 14 are on different sides, causing the handle 11 to protrude relative to the downstream equipment. The protruding part may cause the operator to accidentally touch it, thereby causing the downstream equipment connected to the crank to malfunction. Utility Model Content

[0034] DETAILED DESCRIPTION

[0035] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention. Such variations and improvements are all within the scope of protection of the present invention.

[0036] The utility model provides a crank structure that can solve the problems of customer misoperation and easy breakage of plastic buckles in the prior art. Figure 2-Figure 7 As shown, the crank mechanism comprises a handle 11, a connecting rod 13, and a rotating shaft 14. One end of the connecting rod 13 is connected to the handle 11, and the other end of the connecting rod 13 is rotatably connected to one end of the rotating shaft 14 via a metal connector. In a preferred embodiment, the metal connector comprises a bolt structure. The other end of the rotating shaft 14 is connected to the downstream equipment. In other words, the function of the rotating shaft 4 is to mount the entire crank mechanism on the downstream equipment.

[0037] The crank structure has an operating state and a storage state. When in the operating state, the handle 11 and the rotating shaft 14 are located on different sides of the connecting rod 13. When in the storage state, the handle 11 and the rotating shaft 14 are located on the same side of the connecting rod 13. The handle 11 and the connecting rod 13 are fastened together by screws. The handle 11 is the place where the user operates. The handle 11 is provided with anti-slip grooves. In a preferred embodiment, the anti-slip grooves are linear anti-slip grooves.

[0038] The crank structure also includes an unlocking limit structure, which is used to keep the crank structure in a working state or a storage state. The unlocking limit structure includes an arc rib 41, and a notch groove 42 is provided on the arc rib 41; the arc rib 41 is provided at one end of the rotating shaft 14 connected to the connecting rod 13. The unlocking limit structure also includes a crank unlocking button 12 and a crank spring; the crank unlocking button 12 includes a button portion 210 and an extension portion 220; the crank unlocking button 12 is installed on the connecting rod 13, specifically, the crank unlocking button 12 is installed on the connecting rod 13 through a groove. The crank spring is installed below the crank unlocking button 12; specifically, it can be installed below the button portion 210. The above and below can refer to Figure 3 direction in.

[0039] When no external force acts on the crank unlock button 12, the crank spring is in a normal state, the crank spring pushes the crank unlock button 12 upward, and the extension portion 220 is located in the notch groove 42 and cooperates with the notch groove 42. Figure 4 In area A, the connecting rod 13 cannot rotate relative to the rotating shaft 14;

[0040] When an external force acts on the crank unlock button 12, the external force presses the crank unlock button 12 downward, and the extension portion 220 moves downward to disengage from the notch groove 42. At this time, the extension portion 220 is released from the notch groove 42, and the connecting rod 13 can rotate relative to the rotating shaft 14. At this time, the crank spring is in a compressed state; that is, the operator presses the crank unlock button 12 to disengage the crank unlock button 12 from the rotating shaft 4. Figure 6 In the B area, Figure 7 The C area in the middle plays the role of unlocking.

[0041] The notch groove 42 includes a first notch groove 43 and a second notch groove 44; the first notch groove 43 and the second notch groove 44 are respectively located on both sides of the arc rib 41. When the extension portion 220 is located in the first notch groove 43, the crank structure is in a working state; when the extension portion 220 is located in the second notch groove 44, the crank structure is in a storage state.

[0042] The working principle of this utility model is as follows:

[0043] Figure 2 In normal use, the parts are positioned as follows Figure 4 When the user needs to fold the crank structure, the Figure 3 When the handle unlocking button 12 is in the unlocked position, the extension portion 220 of the handle unlocking button 12 is disengaged from the notch 42 on the shaft 14. Figure 6, so that the assembly formed by the handle 11, the crank unlock button 12, and the connecting rod 13 can rotate along the axis connected to the rotating shaft 14 and the connecting rod 13, as shown Figure 5 , until it rotates to Figure 5 In the stowed state, the extension portion 220 of the crank unlock button 12 of the present invention is securely and reliably connected to the groove of the shaft 14, preventing the crank assembly from rotating due to user error, as is the case with conventional structures. Furthermore, the crank unlock button 12 is relatively strong and will not break easily.

[0044] The utility model also provides a cleaning machine which adopts the crank structure.
