As shown in the figure, Figure 4 and 5 The brake piece 311 is triangular in shape as a whole, has an arc at the bottom, and has a convex portion 311a at the end of the arc. When the spring 32 is compressed, the convex portion 311a is in contact with the cleaning trolley wheel 2. The lower connecting piece 313 is provided with a circular convex portion 313a at the contact position with the brake piece 311, and the brake piece 311 is provided with a circular groove portion 311b matched with the circular convex portion 313a. The upper connecting piece 312 is a shell structure, and the upper connecting piece 312 is connected to the outer side of the brake piece 311 and the outer side of the lower connecting piece 313, respectively.

[0044] Specifically, the brake assembly 31 is assembled from multiple parts, the upper connecting piece 312 is fixedly connected with the bottom seat 1 of the cleaning trolley through fasteners 39, and the lower connecting piece 313 is fixedly connected with the first connecting rod 33 through fasteners 39. Figure 5 and 6 As shown in the drawings, the brake piece 311 and the lower connecting piece 313 are provided with a cylindrical boss on the surface, and the upper connecting piece 312 is provided with a through hole on both sides matched with the cylindrical boss. The through hole of the upper connecting piece 312 is sleeved on the cylindrical boss, so that the brake piece 311 and the lower connecting piece 313 are movably connected with the upper connecting piece 312 respectively. Among them, the brake piece 311 extends out of the opening of the upper connecting piece 312, and the top surface of the extended part of the brake piece 311 is connected with the spring 32.

[0045] Specifically, when the staff steps on the foot pedal 35, the second connecting rod 34 is pressed down, driving the first connecting rod 33 to rotate, and then the lower connecting piece 313 rotates to touch the brake piece 311 to rotate, the cylindrical boss part 313a is buckled with the circular groove part 311b, and the boss part 311a of the brake piece 311 contacts the wheel 2 of the cleaning trolley, so as to realize the braking of the wheel 2; when the foot is released and the toes are hooked on the bottom of the foot pedal 35, the brake piece 311 automatically moves away from the wheel 2 under the elastic force of the spring 32, and the braking state is released.

[0046] In this embodiment, as shown in Figures 2-3 and 7, it also includes a first connecting shaft 37, the upper part of the foot pedal 35 is provided with a groove part, the groove part contains the first connecting shaft 37, and the first connecting shaft 37 is connected with the bottom of the bottom seat 1 of the cleaning trolley.

[0048] In this embodiment, as shown in Figure 2 , the upper surface of the foot pedal 35 is provided with a plurality of protruding pieces 35a.

[0049] Specifically, the design of the protruding pieces 35a can increase the friction of the surface of the foot pedal 35, thereby effectively preventing the foot from slipping.

[0050] In this embodiment, as shown in Figure 7 , the bottom of the foot pedal 35 is a hollow structure.

[0051] Specifically, on the basis of ensuring the stability of the overall structure of the foot pedal 35, the unnecessary material part is removed, the material is saved, the overall weight is reduced, and the stepping action is more light.

[0052] In this embodiment, as shown in Figure 2 and 3As shown, the second connecting rod 34 is connected to the middle end of the first connecting rod 33.

[0053] Specifically, in order to keep the two brake assemblies 31 balanced, and considering the habit of lifting the foot, the foot pedal 35 is arranged in the middle of the cleaning trolley, and thus the second connecting rod 34 is connected to the middle end of the first connecting rod 33. In other embodiments, the second connecting rod 34 can be connected to the left or right end of the first connecting rod 33.

[0054] In the embodiment, as shown in Figure 7 The second connecting rod 34 is connected to the middle end of the first connecting rod 33. Figure 8 As shown, the first connecting rod 33 is connected to the connecting plate 36, and another connecting shaft passes through the connecting plate 36 to connect the first connecting rod 33 and the other end of the second connecting rod 34.

[0055] Specifically, one second connecting shaft 38 connects the foot pedal 35 and the second connecting rod 34, and the other second connecting shaft 38 and the connecting plate 36 connect the first connecting rod 33 and the second connecting rod 34.

[0059] It is also to be noted that, as used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a component" can include a combination of two or more components, and the term "an element" can include comparable reference to a plurality of elements. Additionally, the term "or" as used herein means any one member of a logical disjunction (i.e., it is equivalent to "or" and "or else") and not a logical exclusion. Also, the terms "comprise," "comprising," "include," "including," and the like mean "including but not limited to." Furthermore, the description herein uses terms such as first and second to denote different elements, but the applicants do not intend these terms to denote an ordering, because some of these elements can, in fact, precede other ones in some of the implementations.

[0060] The above description of disclosed embodiments provides examples, and is not intended to be limiting. Numerous modifications of the embodiments, as defined herein, will be apparent to those in the art, and will not depart from the spirit or scope of the application.
