Abstract
Description
Technical Field
[0001] The utility model relates to a mobile experimental platform, belonging to the technical field of experimental platforms. Background Art
[0002] The laboratory bench used for experiments in the laboratory is one of the indispensable equipment in scientific research and experimental work. The design and function of the laboratory bench vary, usually depending on the type and requirements of the experiment being conducted. Laboratory benches usually include the following types: general laboratory benches, which are simple in design and diverse in function, suitable for various types of experiments. They are usually composed of a sturdy metal frame and a durable table top, which is easy to clean and maintain, and accessories such as sockets, sinks, gas interfaces, etc. can be added as needed; biological laboratory benches, which are mainly used for biological experiments, such as cell culture, biochemical experiments, etc. The table top is usually made of easy-to-clean and corrosion-resistant materials, such as stainless steel or special plastics, and may be equipped with accessories such as biological safety cabinets, incubators, microscopes, etc.; chemical laboratory benches, which are specially designed for chemical experiments, such as solution preparation, reaction research, etc. The table top is usually made of corrosion-resistant materials, such as acid-base stainless steel or special chemical plates, and may be equipped with safety guards, chemical storage cabinets and other safety facilities; physical laboratory benches, which are used for physical experiments, such as mechanics, optics, electricity, etc. The table top may have special conductivity or insulation to adapt to different types of experiments, and may be equipped with power supplies, oscilloscopes, light sources and other equipment required for physical experiments.
[0003] A movable laboratory bench is a laboratory bench with casters underneath. The biggest feature of a movable laboratory bench is its flexibility, which allows it to be easily moved to different locations to accommodate changes in laboratory layout or the needs of different experiments. This flexibility enables laboratory space to be used more efficiently and can be quickly adjusted according to experimental requirements. Nevertheless, there are some disadvantages to mobile laboratory benches, including: poor stability. Mobile laboratory benches are usually designed to be lightweight and easy to move, which may sacrifice a certain degree of stability. When conducting complex experiments or experiments that require a high degree of stability, the stability of the laboratory bench may be limited, affecting the accuracy of the experimental results; limited carrying capacity. Since the design of mobile laboratory benches focuses on lightness and portability, their carrying capacity is usually low. Utility Model Content
[0004] Therefore, the purpose of the utility model is to provide a mobile test bench with new casters, which is convenient for the movement of the test bench on the one hand, and for locking the casters on the other hand. At the same time, it has good stability and is convenient for fine-tuning the support height.
[0005] In order to achieve the above-mentioned purpose, the utility model provides a mobile test bench, including a test bench and casters located below the test bench; the casters include a fixing part for fixing to the test bench, a fixing shaft is arranged below the fixing part, a support ring is fixed on the fixing shaft, an annular receiving groove is formed between the support ring and the fixing part, a mounting ring is rotatably sleeved in the receiving groove, a mounting seat is fixed on the mounting ring, and a roller is arranged on the mounting seat; a support block is arranged below the fixing shaft, the support block and the fixing shaft are matched and connected by a screw and a screw hole; the support block and the mounting seat are key-connected, so that when the mounting seat rotates relative to the fixing part, the support block can be driven to rotate together; the support block can be moved down to a position where the lower end face is lower than the roller, and can be moved up to a position where the lower end face is higher than the lowermost end of the roller.
[0006] The screw rod is fixed on the supporting block, and the screw hole is arranged on the lower end surface of the fixed shaft.
[0007] The mounting seat comprises a C-shaped ring, the roller is mounted on both ends of the C-shaped ring via a rotating shaft, and the C-shaped ring sleeves the supporting block therein; the C-shaped ring and the supporting ring are fixedly connected via a connecting arm.
[0008] A gear is also fixed on the fixed shaft and in the gap between the C-shaped ring and the supporting ring.
[0009] The support block is provided with a clearance groove, and a part of the roller enters into the clearance groove.
[0010] By adopting the above technical scheme, the mobile laboratory bench of the utility model can rotate the mounting seat of the caster to rotate the mounting seat, the roller and the support block together when the laboratory bench needs to be pushed. Since the support block is connected to the fixed shaft by a screw, the support block moves up, and when the lower end surface of the support block retracts to the lowermost end of the roller, the roller contacts the ground, and the laboratory bench can be pushed at this time; when the laboratory bench moves to the specified position, the mounting seat is rotated in the opposite direction, and the support block moves down until the lower end surface of the support block is lower than the roller, and the laboratory bench can be supported by the support block, and the height of the support block can also be fine-tuned, which is very convenient to operate.

[0017] The present invention is further described in detail below through the accompanying drawings and specific implementation methods.
[0018] like Figure 1 , 2 As shown, the utility model provides a mobile test bench, comprising a test bench 1 and four casters 2 located below the test bench 1 .
[0019] like Figure 3-6 As shown, the caster 2 includes a fixing member 21 for fixing to the experimental table 1, and the fixing member 21 is fixed to the lower end surface of the experimental table by screws. A fixing shaft 22 is arranged below the fixing member 21, and a supporting ring 23 is fixed on the fixing shaft 22. An annular receiving groove is formed between the supporting ring 23 and the fixing member 21, and a mounting ring 24 is rotatably sleeved in the receiving groove.
[0020] A mounting seat 25 is fixed on the mounting ring 24, and a roller 26 is arranged on the mounting seat 25; a support block 27 is arranged below the fixed shaft 22, and the support block 27 is connected to the fixed shaft 22 by a screw 271 and a screw hole 221; the support block 27 is key-connected with the mounting seat 25, a keyway 273 is arranged on the support block, and a key 252 is arranged on the mounting seat 25, so that when the mounting seat 25 rotates relative to the fixing member 21, the support block 27 can be driven to rotate together; the support block 27 can move downward to a position where the lower end surface is lower than the roller 26, and can move upward to a position where the lower end surface is higher than the lowermost end of the roller 26.
