[0027] Example:

[0028] Reference Figures 1-5A laboratory hazardous waste container transport trolley includes a trolley body 1. A pair of traveling wheels and a pair of omnidirectional wheels are fixedly connected to the bottom plate of the trolley body 1. The omnidirectional wheels have brakes to facilitate the movement of the trolley body 1. A tray 2 is placed on the trolley body 1. The tray 2 has a liquid collection chamber 201 for storing liquid. A drain plate 3 is installed on the top opening of the liquid collection chamber 201. Specifically, an installation groove 202 is opened on the top of the liquid collection chamber 201, and the drain plate 3 is installed in the installation groove 202. Moreover, the bottom surface of the liquid collection chamber 201 is an inclined surface, and a water discharge structure is provided on the side near the lower end of the inclined surface. The water structure is preferably a pipe with a valve. Opening the valve allows the liquid collected in the collection tank 201 to be discharged. During use, a tray 2 is installed on the trolley body 1, a drain board 3 is placed in the mounting groove 202, and then the chemical drum is placed on the drain board 3. When the drum leaks, the leaking liquid will pass through the drain board 3 and enter the collection tank 201, which can prevent chemical leakage during transportation and thus prevent environmental pollution and safety accidents. After use, the tray can be removed from the trolley body 1 to clean the liquid collected in the tray, improving the usage effect. The handle 4, used to operate the trolley body 1, is rotatably connected to one end of the trolley body 1. The handle 4 has a U-shaped structure, making it convenient to push or pull the trolley body 1 for movement. A locking device is installed on the trolley body 1 to limit the rotation of the handle 4. When in use, the handle 4 can be rotated by releasing the locking device. When parked, the handle 4 can be folded to reduce space occupation. Moreover, the working angle of the handle 4 can be adjusted according to usage habits or the user's height to improve the user experience. After adjustment, the locking device locks the handle 4 in the current position to prevent the handle 4 from moving during use and affecting normal use. A guardrail assembly is provided on the trolley body 1, and the tray 2 is located inside the guardrail assembly. When the bucket is placed on the drain plate 3, it can prevent the bucket from falling off the trolley body 1 during transportation. Moreover, when the buckets are fully distributed on the drain plate 3 (preferably four buckets), it can prevent the buckets from tilting and improve stability.

[0029] When in use, the handle 4 is rotated and connected to one end of the trolley body 1. A locking device is provided on the trolley body 1 to restrict the rotation of the handle 4. When the locking device is released, the angle of the handle 4 can be adjusted. On the one hand, the handle 4 can be folded when parked to reduce space occupation. On the other hand, the working angle of the handle 4 can be adjusted according to the user's habits or height to improve the user experience.

[0030] Reference Figure 1 and Figure 4A rotating plate 5 is fixedly connected to one end of the trolley body 1 in a symmetrical arrangement. There are two rotating plates 5 symmetrically arranged. A rotating shaft 401 is fixedly connected to both ends of the handle 4. A rotating hole 501 is opened on both rotating plates 5. The rotating shaft 401 is rotatably connected to the rotating hole 501, which can ensure that the handle 4 is reliably rotatably connected to the trolley body 1 and improve the use effect.

[0031] Reference Figure 4 The locking mechanism can be a bolt or a snap-fit. After adjustment, the handle 4 is fixed to the rotating plate 5. Here, the locking mechanism is designed with a fixed cylinder 6 fixedly connected to the handle 4, and a pin 601 is slidably connected inside the fixed cylinder 6. Multiple circumferentially distributed insertion holes 502 are provided on one of the rotating plates 5. There are two to ten insertion holes 502; here, we prefer four, and the line connecting the four insertion holes 502 is a quarter-circle arc. In use, the handle 4 has four positions, the first being vertically upward, which facilitates pushing the trolley body 1. The handle 4 is in a horizontal position when the trolley body 1 is in motion. The second and third handles are located between the first and fourth handles. When the trolley body 1 is parked, the handle 4 can be folded downwards to a vertically downward electric position, improving the usability. One end of the pin 601 is extended into the insertion hole 502 to restrict the handle 4 to its current position. A pull plate is fixedly connected to the other end of the pin 601. In use, the pin 601 is pulled by the pull plate to disengage it from the insertion hole 502. At this time, the position of the handle 4 can be adjusted. The adjustment is convenient and the fixation is reliable, which helps to improve the usability.

[0032] Specifically, a limiting plate is slidably connected inside the fixed cylinder 6, and the pin 601 is fixedly connected to the limiting plate. A spring is sleeved on the pin 601, and the two ends of the spring abut against the limiting plate and the fixed cylinder 6 respectively. In use, by sleeved on the pin 601, when the pin 601 is inserted into the insertion hole 502, the pin 601 can always be inserted into the insertion hole 502 without the action of external force, thereby improving the fixing effect between the handle 4 and the rotating plate 5.

[0033] Reference Figures 1-3Here, we design the fence assembly as two sets of side rails 104. A front baffle 102 and a rear baffle 103 are fixedly connected to both ends of the trolley body 1, respectively. The height of the front baffle 102 is higher than that of the rear baffle 103. The height of the rear baffle 103 and the side rails 104 are the same and located at one-half or one-third of the height of the bucket, preferably one-half, to facilitate the placement of the bucket. One end of each set of side rails 104 is rotatably connected to both sides of the front baffle 102. Here, we prefer to rotatably connect them to the front baffle 102 via hinges. The other end of each set of side rails 104 is inserted and connected to the rear baffle 103 via pins. In use, by rotatably connecting one end of the side rail 104 to the front baffle 102 and detaching the other end of the side rail 104 from the rear baffle 103, it is easy to open the side rail 104. At this time, it is easy to pull the tray out from the trolley body 1 for cleaning, thus improving the usage effect.

[0034] Reference Figures 1-3 An item bag 101 is fixedly connected to the outer wall of both the front baffle 102 and the rear baffle 103. The item bag 101 can be a mesh bag or transparent plastic, used to place item requisition record sheets, waste disposal record sheets, etc., to improve the efficiency of use.
