[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0031] Combine the following Figures 1 to 8 A cleaning brush lifting auxiliary structure according to an embodiment of the utility model is described in detail.

[0032] like Figures 1 to 8As shown, a cleaning brush lifting auxiliary structure according to an embodiment of the utility model includes: a fixed plate 102, a clamping plate 104, a movable rod 106, a movable clamping member 110, etc. An integrally formed clamping plate 104 is provided at the bottom end of the fixed plate 102, and the movable rod 106 is connected to the middle area of ​​the fixed plate 102 by a rotating shaft 108, and the movable rod 106 can rotate relative to the fixed plate 102. The movable clamping member 110 is movably connected to the movable rod 106 by a connecting rod 112 vertically arranged on the movable rod 106, and the movable clamping member 110 not only moves with the movable rod 106, but also rotates relative to the movable rod 106. The connecting rod 112 and the rotating shaft 108 are arranged on the movable rod 106 at intervals and in parallel, and an L-shaped notch 1102 is provided at one end of the movable clamping member 110, and the L-shaped notch 1102 can be used to realize the clamping fixation and movable separation between the clamping plate 104 on the fixed plate 102. Specifically, the movable rod 106 is connected to the cleaning brush bracket, and the movable rod 106 is bent downward, and the shorter side 1106 of the movable engaging member 110 slides obliquely from top to bottom along the engaging plate 104 until the L-shaped notch 1102 is stuck at the bottom end of the engaging plate 104, thereby lifting and fixing the cleaning brush. The movable rod 106 is further bent downward, and the piston engaging member rotates, and its longer side 1104 contacts the engaging plate 104, and the movable rod 106 is released. Under the action of the gravity of the cleaning brush, the longer side 1104 of the movable engaging member 110 slides obliquely from bottom to top along the engaging plate 104, thereby lowering the cleaning brush, which is very labor-saving and improves the convenience of lifting and lowering the cleaning brush.

[0033] Furthermore, if Figure 3 , Figure 5 and Figure 6 As shown, the bottom of the fixed plate 102 is an isosceles triangle with the vertex at the bottom, and the angle of the vertex is 120°. The clamping plate 104 is connected to one waist of the isosceles triangle and is perpendicular to the fixed plate 102, so that the movable clamping member 110 can be clamped and fixed thereto. As long as the movable rod 106 is bent down, the shorter side 1106 of the movable clamping member 110 slides along the clamping plate 104 from top to bottom until the L-shaped notch 1102 is clamped at the bottom of the clamping plate 104, and the cleaning brush can be lifted and fixed. As long as the movable rod 106 is bent down with a little force, so that the L-shaped notch 1102 is separated from the clamping plate 104, the movable clamping member 110 will rotate under the action of gravity, and the longer side 1104 will contact the clamping plate 104. Under the action of the gravity of the cleaning brush, the cleaning brush can be lowered, which is very labor-saving.

[0034] Furthermore, if Figures 1 to 3As shown, a connection hole 1062 is provided at one end of the movable rod 106, and a cleaning brush bracket can be connected through a hinge structure, so that the cleaning brush can be driven to move up and down through the movable rod 106. A handle 1064 is provided at the other end of the movable rod 106, which is convenient for the operator to grasp and operate. Specifically, when the movable engaging member 110 is engaged and fixed with the engaging plate 104, the connection hole 1062 is at a higher position, the handle 1064 is at a lower position, and the cleaning brush is lifted; when the movable engaging member 110 is separated from the engaging plate 104, the connection hole 1062 is at a lower position, the handle 1064 is at a higher position, and the cleaning brush is lowered.

[0035] Furthermore, if Figure 7 and Figure 8 As shown, the angle between the longer side of the L-shaped notch 1102 of the movable engaging member 110 and the side of the movable engaging member 110 is 60°, and the angle between the shorter side of the L-shaped notch 1102 of the movable engaging member 110 and the side of the movable engaging member 110 is 30°. Thus, the movable engaging member 110 is more convenient to engage with the engaging plate 104 and to detach from the engaging plate 104, which is more labor-saving.

[0036] Furthermore, if Figure 6 and Figure 8 As shown, the length of the engaging plate 104 is 24 mm and the thickness is 4 mm; the other end of the movable engaging member 110 is semicircular, and the length of the shorter side of the L-shaped notch 1102 is 5 mm. Thus, the convenience of engaging and disengaging is further improved, and more labor-saving is achieved.

[0037] Furthermore, if Figure 6 and Figure 8 As shown, the length of the longer side of the L-shaped notch 1102 of the movable engaging member 110 is less than the length of the engaging plate 104; the length of the longer side 1104 of the movable engaging member 110 is greater than the length of the engaging plate 104, and the length of the shorter side 1106 of the movable engaging member 110 is less than the length of the engaging plate 104.

[0038] Thus, the handle 1064 is pushed downward, and the shorter side 1106 of the movable engaging member 110 slides obliquely downward from top to bottom along the engaging plate 104 until the L-shaped notch 1102 is stuck at the bottom end of the engaging plate 104, thereby lifting and fixing the cleaning brush. The handle 1064 is pushed downward further, and the piston engaging member rotates, and its longer side 1104 contacts the engaging plate 104, and the handle 1064 is released. Under the action of the gravity of the cleaning brush, the handle 1064 rises, and the longer side 1104 of the movable engaging member 110 slides obliquely upward from bottom to top along the engaging plate 104, thereby lowering the cleaning brush, which is very labor-saving.

[0039] Furthermore, if Figures 1 to 6As shown, the fixing plate 102 is provided with a mounting hole 1022, so as to be fixedly mounted on the vehicle frame through a fixing member, generally fixedly mounted above the central axis of the vehicle frame, so as to facilitate connecting the connecting hole 1062 of the movable rod 106 to the central position of the cleaning brush bracket, further facilitating operation and saving more effort. The fixing member can be a bolt or the like.

[0040] The working process of the cleaning brush lifting auxiliary structure proposed in the utility model is as follows:

[0041] The fixing plate 102 is fixed to the frame by two bolts passing through the two mounting holes 1022 on the fixing plate 102 respectively; the movable rod 106 is connected to the through hole opened in the middle area of ​​the fixing plate 102 through the rotating shaft 108; the cleaning brush bracket is connected to the connecting hole 1062 of the movable rod 106 through a hinge structure; when the handle 1064 is at a higher position and the connecting hole 1062 is at a lower position, the cleaning brush is in a lower state; the handle 1064 is pushed downward, and the shorter side 1106 of the movable engaging member 110 slides from top to bottom along the engaging plate 104 until the L-shaped notch 1102 is stuck at the bottom end of the engaging plate 104, thereby realizing the lifting and fixation of the cleaning brush. Continue to push the handle 1064 downward, the piston engaging part rotates, the L-shaped notch 1102 disengages from the engaging plate 104, and the longer side 1104 of the movable engaging part 110 contacts the engaging plate 104. Release the handle 1064, and under the action of the gravity of the cleaning brush, the handle 1064 rises, and the longer side 1104 of the movable engaging part 110 slides upward along the engaging plate 104, thereby lowering the cleaning brush.

[0042] The small sanitation vehicle comprises the above-mentioned cleaning brush lifting auxiliary structure, the fixing plate of the cleaning brush lifting auxiliary structure is fixedly installed on the vehicle frame, and the connecting hole of the movable rod is connected with the cleaning brush bracket through a hinge structure.
