[0029] Embodiment 1

[0030] Please refer to Figure 1-6 As shown, this embodiment provides a cleaning machine frame, including a frame main body 1 and a handle member 2.

[0031] The frame main body 1 is mainly used for installing the units 5 of the cleaning machine, such as a high-pressure pump, an engine, etc.

[0032] The bottom of the frame main body 1 is provided with rollers 10. Specifically, there are two rollers, which are arranged at the rear side of the bottom of the frame main body 1. Correspondingly, feet 13 are provided at the front side of the bottom of the frame main body 1, and the frame main body 1 is supported by the cooperation of the rollers 10 and the feet 13.

[0033] The frame body 1 can be flipped with the roller 10 as a fulcrum. When the cleaning machine needs to be moved, the handle member 2 is pressed downward with force to make the frame body 1 flip with the roller 10 as a fulcrum until the support foot 13 is off the ground. At this time, the entire cleaning machine is supported by the roller 10 on the ground; in this way, the cleaning machine can be pulled or pushed to walk and move.

[0034] like Figure 1 As shown, the handle member 2 includes a gripping portion 21, wherein the gripping portion 21 is mainly used as a position for human hand to exert force and hold, that is, by pressing the gripping portion 21 downward, the frame body 1 is driven to flip, and then the gripping portion 21 is held to pull or push the entire cleaning machine to move.

[0035] In addition, in this embodiment, the handle member 2 is a component independent of the frame body 1, and can be assembled to the frame body 1 in a detachable manner. Specifically:

[0036] like Figure 1 As shown, the handle member 2 also includes a plug-in end 22. Accordingly, the frame body 1 is provided with two docking ends. The plug-in end 22 can be detachably plugged into and matched with any one of the two docking ends, so that the handle member 2 can switch between the first form and the second form.

[0037] For the convenience of explanation, Figure 1 As shown, in this embodiment, the two butt joint ends are respectively recorded as a first butt joint end 11 and a second butt joint end 12;

[0038] like Figure 3 As shown, when the plug-in end 22 is plugged into the first docking end 11, the handle member 2 is in the first form;

[0039] like Figure 2 As shown, when the plug-in end 22 is plugged into the second docking end 12 , the handle member 2 is in the second configuration.

[0040] like Figure 4 As shown, compared with the handle member 2 in the first form, in the second form, the grip portion 21 is farther from the center of the roller 10 in the horizontal direction, and the grip portion 21 is lower in the vertical direction from the center of the roller 10. Specifically:

[0041] like Figure 4 As shown:

[0042] When the handle member 2 is in the first form, the horizontal distance between the grip portion 21 and the center of the roller 10 is recorded as a first distance L1, and the vertical height between the grip portion 21 and the center of the roller 10 (ie, the vertical distance between the grip portion 21 and the center of the roller 10) is recorded as a first height H1.

[0043] When the handle is in the second form, the distance between the holding portion 21 and the center of the roller 10 in the horizontal direction is denoted as the first distance L2, and the height of the holding portion 21 from the center of the roller 10 in the vertical direction (i.e., the vertical distance between the two) is denoted as the first height H2.

[0044] As described above, compared with the handle member 2 in the first form, when the handle member 2 is in the second form, the distance between the holding portion 21 and the center of the roller 10 in the horizontal direction is farther, and the height of the holding portion 21 from the center of the roller 10 in the vertical direction is lower. Combining Figure 4 It can be understood that the first distance L1 is less than the second distance L2; the first height H1 is greater than the second height H2.

[0045] It should be noted that the aforementioned first distance L1, second distance L2, first height H1, and second height H2 are all defined when the roller 10 and the support feet 13 are both on the ground, or are defined in the parked state of the cleaning machine, that is Figure 4 the state shown.

[0046] In addition, regardless of whether it is the first form or the second form, the holding portion 21 extends to the rear side of the roller 10 (i.e., the side of the roller 10 away from the support feet 13), so as to ensure that when the holding portion 21 is pressed downward, the frame can be flipped with the roller 10 as the fulcrum to lift the support feet 13.

[0047] It can be understood that the first distance L1 and the second distance L2 are equivalent to the force arms when pressing the holding portion 21 to drive the frame body 1 to flip. Since the first distance L1 is less than the second distance L2, when pressing the holding portion 21 to lift the support feet 13 in the second form, the force arm is greater than the force arm when pressing the holding portion 21 to lift the support feet 13 in the first form. Therefore, compared with the first form, when pressing the holding portion 21 to lift the support feet 13 in the second form, it is obviously more labor-saving.

[0048] That is to say, if you want to press and lift the support feet 13 in a more labor-saving way, you can choose to assemble the handle member 2 to the frame body 1 in the second form.

[0049] It can be seen that in this solution, by providing two docking ends for the insertion end 22 of the handle member 2 to be inserted, the user can select a docking end as the insertion part of the insertion end 22 according to their own needs, so that the handle member 2 presents different usage forms, thereby making the entire frame present two different assembly states to improve the adaptability of the frame.

[0050] For example, when the user hopes that the grip of the handle member 2 is higher, at this time, the user can insert the handle member 2 into the docking end corresponding to the first form (i.e., the first docking end 11), that is Figure 3 the state shown;

[0051] Conversely, if you want to lower the grip of the handle member 2, the handle member 2 can be inserted into the docking end corresponding to the second form (i.e., the second docking end 12), that is Figure 2 the state shown.

[0052] For the specific insertion method of the docking end and the insertion end 22, it can be:

[0053] As Figure 3 shown, the insertion end 22 is inserted and cooperated with the first docking end 11 along the first direction to switch the handle member 2 to the first form; as Figure 2 shown, the insertion end 22 is inserted and cooperated with the second docking end 12 along the second direction to switch the handle member 2 to the second form.

[0054] Among them, the first direction is different from the second direction. Preferably, as Figure 1 shown, in the projection of the width direction of the frame, the first direction and the second direction are arranged at an angle α. Here, the width direction can also be understood as the axial direction of the roller 10.

[0055] For the convenience of description, the side of the frame body 1 where the roller 10 is provided is denoted as the rear side of the bracket body, and the side where the support feet 13 are provided is denoted as the front side of the frame body 1. In some embodiments, the first docking end 11 is located at the rear side of the frame body 1 and extends upward. Here, the upward direction is not limited to the absolute vertical direction, and it can also be inclined relative to the vertical direction towards the rear side of the roller 10.

[0056] In addition, the second docking end 12 is located at the front side of the frame body 1 and extends obliquely upward towards the first docking end 11. In some embodiments, the first docking end 11 and the second docking end 12 on the same side are in the same vertical plane.

[0057] For example, as Figure 1 shown, the frame body 1 includes side frames 14 provided on both sides. The side frames 14 are tube structures. One end of the side frame 14 extends upward on the side where the roller 10 is located to form the first docking end 11, and the other end extends obliquely towards the first docking end 11 to form the second docking end 12.

[0058] As Figure 1 shown, in this embodiment, the first direction can be understood as the axial direction D1 of the first docking end 11, and the second direction can be understood as the axial direction D2 of the second docking end 12.

[0059] In order to improve the insertion firmness between the handle member 2 and the frame body 1, in some embodiments, as Figure 1As shown, there are two plug-in ends 22, and both the first docking ends 11 and the second docking ends 12 also include two. The two first docking ends 11 respectively correspond to the two plug-in ends 22 one by one for the two plug-in ends 22 to be inserted respectively; correspondingly, the two second docking ends 12 also respectively correspond to the two plug-in ends 22 one by one for the two plug-in ends 22 to be inserted respectively. Specifically, one first docking end 11 and one second docking end 12 are provided on each of the side frames 14 on both sides.

[0060] In this way, there are equivalent to two plug-in and mating points between the handle member 2 and the frame body 1, ensuring that after their plug-in combination, they can be more stable.

[0061] As for the specific structure of the two plug-in ends 22, it can be, for example Figure 1 As shown, the handle member 2 has a U-shaped rod structure; both ends of the handle member 2 respectively form the two plug-in ends 22; the middle rod of the handle member 2 constitutes the holding portion 21. In some embodiments, in the handle member 2, the rod portions on both sides of the holding portion 21 have a certain bending angle.

[0062] Since the plug-in and mating structures of the plug-in end 22 and each docking end are basically the same, in this embodiment, one of them will be taken as an example for specific description:

[0063] Combined with Figure 1 As shown, the plug-in end 22 includes a plug 221, and an elastic pin 3 capable of radially expanding and contracting along the plug 221 is provided on the plug 221. The elastic pin 3 refers to a pin structure capable of elastic expansion and contraction.

[0064] In some embodiments, the specific structure of the adopted elastic pin 3 is:

[0065] For example Figure 5 As shown, the elastic pin 3 includes a pin body 31 and a U-shaped elastic piece 32. The plug 221 has a channel for installing the elastic piece 32 inside. For example, the plug 221 is a tubular structure, and its internal pipeline constitutes the channel; the elastic piece 32 and the pin body 31 are integrally inserted into the channel, and one end of the elastic piece 32 abuts against or is fixed to the side wall of the channel, and the other end is fixed to the pin body 31. The pin body 31 is movably inserted through the plug 221 along the radial direction of the plug 221, and the elastic piece 32 provides an elastic force for the pin body 31 to drive the pin body 31 to have a tendency to radially extend outward along the plug 221.

[0066] For example Figure 6As shown, correspondingly, the docking end includes a socket 111, and the socket 111 is provided with a locking hole 112 for inserting the pin body 31 of the elastic pin 3. When assembling the handle member 2, the plug 221 is inserted into the socket 111. During the insertion process, the pin body 31 contracts inwardly against the elastic force of the elastic piece 32. When the pin body 31 moves to the position of the locking hole 112, under the elastic force of the elastic piece 32, the pin body 31 is pushed to move outwardly to insert into the locking hole 112. In this way, the plug 221 is locked in the socket 111. When it is necessary to remove the handle member 2, just press the pin body 31 inwardly, and then pull the handle member 2 outwardly with force to extract the handle member 2.

[0067] It can be understood that the positions of the plug 221 and the socket 111 can be interchanged, that is, in addition to the above method, it can also be that the plug 221 is provided at the docking end and the socket 111 is provided at the plug-in end 22.

[0068] Since when the handle member 2 is assembled to the frame body 1, only part of the docking end is occupied, and the other part of the docking end is in an idle state; for example, as Figure 3 shown, when the plug-in end 22 is plugged into the first docking end 11, the second docking end 12 is in an idle state. In this way, the orifice of the socket 111 of the second docking end 12 is exposed, which is neither beautiful nor may some external impurities enter the socket 111. Therefore, in some embodiments, a cover 4 is further provided, and the cover 4 can be detachably installed on the socket 111 to block the orifice of the socket 111. The cover 4 is mainly used to block the idle socket 111, on the one hand, it plays a decorative role, and on the other hand, it blocks the orifice of the socket 111 to prevent external impurities from entering.

[0069] Embodiment 2

[0070] Combined with Figure 1-6 shown, on the basis of Embodiment 1, this embodiment further provides a cleaning machine, including a frame and a unit 5 provided on the frame, wherein the frame adopts the cleaning machine frame provided in Embodiment 1. It can be understood that the cleaning machine further includes a spray gun 6, and high-pressure water flow is sprayed by the spray gun 6 during work to achieve the cleaning purpose.

[0071] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
