Description

Technical Field

[0001] This utility model belongs to the field of laboratory equipment, specifically relating to a trolley for placing a laboratory desiccator. Background Technology

[0002] In routine laboratory testing, it is common to encounter situations where samples need to be cooled in a desiccator after high-temperature drying before weighing. Desiccators are commonly used instruments in laboratory physicochemical testing. The most common laboratory desiccators are made of thick glass, which is heavy, smooth, and fragile. If they are moved manually, it is time-consuming and laborious, greatly reducing work efficiency; at the same time, there is also a risk of dropping and breaking them during handling.

[0003] Based on the above problems, CN216232375U discloses a dryer trolley, which is equipped with an adjustable support plate for fixing the dryer and a protective net to prevent the dryer from falling. The trolley is also equipped with a push handle and casters to facilitate the movement of the dryer.

[0004] However, laboratory glass desiccators are typically heavy, and the above-mentioned technical solutions rely solely on a support plate as the sole structural support for the desiccator's weight, making them prone to damage. Furthermore, the trolleys used in these solutions are expensive, hindering their widespread adoption in laboratories. Additionally, laboratory desiccators require the lid to be opened for use, and the lid's edge is coated with petroleum jelly for sealing. It cannot be placed directly on a table, necessitating a convenient and safe storage space for the desiccator lid. Utility Model Content

[0005] To solve the above problems, this utility model provides a simple laboratory desiccant cart.

[0006] A trolley for placing a laboratory desiccator consists of an upper shelf (1), a lower shelf (2), a trolley support column (3), and a trolley handle (4); the upper shelf (1) is surrounded by an upper shelf guardrail (11); the lower shelf (2) is surrounded by a lower shelf guardrail (21), and the lower shelf guardrail (21) has a desiccator lid handle groove (22); the trolley support column (3) has wheels (31) at its bottom.

[0007] The handle groove (22) of the dryer cover is a hollow groove with an open end. When the dryer is opened, because the cover is coated with Vaseline for sealing, the cover cannot be placed face up. The cover can be turned upside down and its handle can be placed in the handle groove (22) of the dryer cover.

[0008] The dryer cover handle groove (22) can be more than one. Depending on the size of the handle of different dryer covers, 1 to 5 grooves can be designed. It is necessary to ensure that there is enough distance between the two handle grooves to ensure the stability of the guardrail.

[0009] Preferably, the bottom width of the handle groove (22) of the dryer cover is smaller than the top width, and the position where its upper end connects to the lower shelf guardrail (21) is rounded.

[0010] More preferably, the width of the bottom of the dryer cover handle groove (22) is less than the maximum outer diameter of the dryer cover handle, but greater than the minimum outer diameter of the dryer cover handle.

[0011] Preferably, the position of the handle groove (22) of the dryer lid on the lower shelf guardrail (21) is tilted outward at a 20-45° angle relative to the direction perpendicular to the ground. This position ensures that the dryer lid is securely locked and fully supported by the lower shelf, resulting in high safety.

[0012] Preferably, the upper shelf guardrail (11) is provided with an elastic fixing rope (12). When the dryer is small, the elastic fixing rope (12) can help fix the dryer and prevent it from shifting or tipping over.

[0013] The upper shelf (1), upper shelf guardrail (11), lower shelf (2) and lower shelf guardrail (21) can be mesh or flat. While ensuring sufficient load-bearing capacity, the mesh structure can reduce the cost of the device.

[0014] Preferably, when the upper shelf guardrail (11) is a flat plate, elastic fixing rope fixing holes (13) are provided around its upper perimeter so that the position of the elastic fixing rope (12) can be flexibly selected according to the size of the dryer; when the upper shelf guardrail (11) is a mesh, there is no need to specially set elastic fixing rope fixing holes because it has its own mesh.

[0015] More preferably, the end of the elastic fixing rope (12) has a metal hook for quick fixing to the elastic fixing rope fixing hole (13).

[0016] Preferably, the upper shelf (1) and the lower shelf (2) are circular to accommodate the circular shape of the laboratory desiccator.

[0017] Preferably, the area of ​​the lower shelf (2) is larger than that of the upper shelf (1), and the normal central axes of the upper shelf (1) and the lower shelf (2) coincide. This structure can make the trolley more stable and avoid the risk of tipping over. More preferably, the area of ​​the lower shelf (2) is greater than or equal to 1.5 times the area of ​​the upper shelf (1). When the shapes or dimensions of the upper and lower shelves are inconsistent, the load-bearing column is bent to adapt to the change in shelf size.

[0018] Preferably, the height of the upper shelf guardrail (11) is 30-50cm, which exceeds the height of commonly used dryers, to ensure the safety of the dryer.

[0019] Preferably, the main body of the trolley is made of stainless steel or ultra-high strength plastic, and the components are connected by welding or integral molding to ensure the trolley's sturdiness.

[0020] Preferably, the wheels (31) at the bottom of the trolley support column (3) are omnidirectional wheels; more preferably, the wheels (31) are equipped with a braking device.

[0021] The trolley for placing laboratory desiccators provided by this utility model has a simple structure and requires low manufacturing cost. It can effectively reduce the handling intensity of laboratory personnel, improve work efficiency, and enhance the safety of desiccator handling. Furthermore, the trolley features a double-layer shelf; the top layer holds the desiccator, while the bottom layer can hold the desiccator lid and other auxiliary supplies. The bottom guardrail has a dedicated handle groove for the desiccator lid, making lid placement and removal convenient and safe. Attached Figure Description
