[0030] The utility model provides a lifting test bench, which provides a stable foundation for the entire lifting test bench through the structure of the supporting base, including a bottom platform and support columns. At the same time, the first lifting member and the second lifting member in the lifting assembly are connected by sliding, combined with the adaptation setting of the clip and the opening, to ensure stability and safety during the lifting process. This structure effectively prevents the risk of the table top suddenly dropping or falling, and ensures the safety of the experimenters and equipment. Among them, the structure of the lifting assembly and the drive assembly takes maintainability into consideration. The adaptation setting of the clip and the opening facilitates the inspection and replacement of worn parts; the modular setting of the drive assembly makes it simple and quick to repair and replace the drive parts. This reduces maintenance costs and extends the service life of the equipment. Example

[0031] The present invention provides a lifting test platform. Figures 1 to 3 As shown, the support base 10 includes a base 110 and a support column 120, and the support column 120 is arranged on the base 110; the lifting assembly 20, the lifting assembly 20 includes a first lifting member 210 and a second lifting member 220, the first lifting member 210 is slidably connected to the second lifting member 220, the second lifting member 220 is connected to the support column 120, the first lifting member 210 includes at least one clamping member 230, and the second lifting member 220 is provided with an opening 240 adapted to the clamping member 230; the connecting member 30, one side of the connecting member 30 is connected to the table top of the lifting test bench, and the other side is connected to the first lifting member 210; the driving assembly 40, the driving assembly 40 includes a driving member 410 and a driving rod 420, one end of the driving rod 420 is connected to the connecting member 30, and the driving member 410 is used to drive the driving rod 420, thereby driving the lifting assembly 20 to rise and fall.

[0032] Thus, the support base 10, comprising the base 110 and support columns 120, provides a stable foundation for the entire lifting platform. Furthermore, the sliding connection between the first and second lifting members 210, 220 in the lifting assembly 20, combined with the adaptability of the clamping member 230 and the opening 240, ensures stability and safety during the lifting process. This structure effectively prevents the risk of the platform suddenly dropping or falling, ensuring the safety of laboratory personnel and equipment.

[0033] The drive assembly 40 includes a drive member 410 and a drive rod 420. By precisely controlling the output of the drive member 410, fine adjustment of the lifting assembly 20 can be achieved. This allows the lifting test platform to accurately reach a predetermined height, meeting the accuracy requirements of experiments or work.

[0034] The connection member 30 tightly connects the tabletop to the lifting assembly 20, and one end of the drive rod 420 is connected to the connection member 30, simplifying the lifting operation. The user can easily raise and lower the lifting table by simply controlling the drive member 410, improving work efficiency and convenience.

[0035] The lift assembly 20 and drive assembly 40 are designed with the equipment's maintainability in mind. For example, the adaption of the clip 230 to the opening 240 facilitates inspection and replacement of worn parts. The modular design of the drive assembly 40 makes repair and replacement of the drive member 410 simple and quick. This reduces maintenance costs and extends the equipment's service life.

[0036] This type of lifting platform is flexible and can be customized to suit different experimental or work requirements. For example, by adjusting the height of the support column 120, replacing the clamping member 230 and the driving member 410 with different specifications, etc., it can meet the lifting requirements of different heights and different load conditions. This improves the applicability and flexibility of the lifting platform.

[0037] More specifically, the first lifting member 210 may be provided with a plurality of clamping members 230 in sequence in the direction of sliding movement with the second lifting member 220 .

[0038] In this way, multiple clips 230 are provided. The number of clips 230 can be two or more, and each clip 230 can be configured to precisely mate with the opening 240 on the second lift member 220 and sequentially lock and unlock during the lifting process. This means that at every stage of the lifting process, at least one clip 230 is in operation, ensuring the stability and stability of the lifting platform. Furthermore, the multi-stage clip connection allows for more precise height adjustment to meet the height requirements of different experiments or workstations. These clips 230 are evenly distributed along the lifting direction, ensuring smooth lifting and uniform force distribution. Even under high loads or rapid lifting, sudden instability or sudden drop of the platform surface can be effectively avoided. Because the clips 230 are removable or adjustable, users can adjust the number, position, or shape of the clips 230 to suit different application scenarios and load conditions. This flexibility makes the lifting platform more practical and efficient. Even if a clip 230 fails due to malfunction or wear, the remaining clips 230 will continue to function, providing additional safety. This safety redundancy reduces the risk of a single fault causing the entire system to fail.

[0039] like Figure 2As shown, the second lifting member 220 is provided with a recessed area 250 in the area where the opening 240 is provided. More specifically, the length of the clamping member 230 extending out of the opening 240 is less than the depth of the recessed area 250. In this way, it is avoided that the clamping member 230 abuts against other components of the laboratory bench when the clamping member 230 is engaged with the opening 240. The second lifting member 220 is provided with a recessed area 250 in the area where the opening 240 is provided. This structure not only provides sufficient space for the clamping member 230 to ensure smooth engagement and unlocking actions, but also avoids unnecessary abutment or interference between the clamping member 230 and other components of the laboratory bench during operation. The depth of the recessed area 250 can be carefully calculated to ensure that when the clamping member 230 is fully engaged with the opening 240, the length thereof extending out of the opening 240 is still less than the depth of the recessed area 250. This ensures a good fit between the clip 230 and the second lifting member 220, while avoiding direct contact between the clip 230 and other structural components of the laboratory bench, thereby reducing wear and noise. Since the clip 230 will not exceed the range of the recessed area 250, even during the lifting process, the clip 230 will not interfere with the support base 10, table top or other accessories of the laboratory bench. This helps to maintain the overall stability and reliability of the lifting laboratory bench, while also simplifying the setup and maintenance process. The presence of the recessed area 250 also optimizes the structural layout of the second lifting member 220, making the entire lifting assembly 20 more compact and efficient. This structure can also help to reduce material usage, reduce manufacturing costs, and improve the overall performance of the lifting laboratory bench.

[0040] like Figure 1 As shown, the driving rod 420 and the first lifting member 210 are both disposed on the same side of the connecting member 30. More specifically, the device may further include a sensor and a controller electrically connected to the sensor, the controller being used to control the ejection of the clamping member 230.

[0041] The drive rod 420 is cleverly positioned on the same side of the connector 30, working in conjunction with the first lift member 210. This configuration allows for more direct and efficient power transmission, reducing energy loss and mechanical wear during the transmission process. It also simplifies the structure of the lift platform, making it more compact and easier to maintain.

[0042] Sensors can be installed at key locations on the lift platform. Their primary task is to monitor the platform's motion in real time. Specifically, these sensors are designed to detect whether the platform is falling or rapidly descending. If a sensor detects abnormal velocity or acceleration, it immediately identifies this as a potential fall or rapid descent and responds quickly.

[0043] When the sensor detects a falling or rapidly descending platform, it immediately sends an emergency signal to the controller. This signal contains critical information about the platform's current state, such as speed, acceleration, and possible direction. Upon receiving this signal, the controller immediately analyzes and determines the situation based on pre-set safety procedures.

[0044] Once the lab bench is confirmed to be in an unsafe state, the controller quickly activates an emergency response mechanism. The core of this mechanism is controlling the ejection of the latch 230. The controller sends instructions to the actuators of the latch 230 (e.g., electromagnets, pneumatic devices, etc.), instructing them to immediately eject the latch 230 from its current position and attempt to reengage it with the opening 240 on the second lifter 220.

[0045] Upon receiving the controller's command, the connector quickly responds and pops out. Because the latching member 230 is configured to tightly mate with the opening 240 on the second lifter 220, once successfully engaged, it effectively prevents the lab bench from descending further. This instant locking mechanism provides a solid support point for the lab bench, preventing damage and danger from a fall or rapid descent.

[0046] like Figure 3 As shown, the clamping member 230 is provided with an elastic member 2310. More specifically, the elastic member 2310 is sleeved on the clamping member 230. When the clamping member 230 is clamped with the opening 240, the elastic member 2310 is in its original state. More specifically, the elastic member 2310 is a spring.

[0047] Specifically, the elastic member 2310 is sleeved on the clamping member 230 to form a composite structure. This structure allows the clamping member 230 to optimize the clamping process and ensure the stability of the clamping when the clamping member 230 is clamped with the opening 240 by utilizing the mechanical properties of the elastic member 2310.

[0048] More specifically, the elastic member 2310 is selected to be a spring. As a common elastic element, the spring has good elasticity and restoring force. It can deform when subjected to an external force and quickly return to its original state after the external force disappears. After the spring is sleeved on the clamping member 230, when the clamping member 230 attempts to engage with the opening 240, the spring will provide a certain pre-tightening force to help the clamping member 230 enter the opening 240 more smoothly and reach a stable position. At the same time, during the lifting process, if the clamping force between the clamping member 230 and the opening 240 is weakened due to some reason (such as vibration, load change, etc.), the restoring force of the spring will also play a supplementary role to prevent the clamping member 230 from accidentally falling off.

[0049] The introduction of the spring provides additional preload and restoring force to the connector 230, making the connection between the connector 230 and the opening 240 more secure and reliable. This allows the connector 230 to maintain a stable connection even under adverse conditions such as vibration or load fluctuations. The spring's elastic properties provide a certain degree of cushioning and guidance when the connector 230 enters the opening 240, reducing impact and wear during the connection process. Furthermore, the spring's preload helps the connector 230 more accurately position itself within the opening 240, improving the efficiency and accuracy of the connection. In the event of an abnormal situation such as a fall or rapid descent, the spring's restoring force quickly responds and strengthens the locking effect of the connector 230, preventing the platform from further descending or falling. This instant locking mechanism provides additional safety for the platform. Due to the spring's cushioning and guiding effects, as well as its enhanced stability, the entire platform is less susceptible to impact and wear during use, thereby extending the life of the device.

[0050] Compared with the prior art, the embodiment of the present invention provides a lifting test bench, which provides a stable foundation for the entire lifting test bench through the structure of the supporting base, including a base and a support column. At the same time, the first lifting member and the second lifting member in the lifting assembly are connected by sliding, combined with the adaptation setting of the clip and the opening, to ensure stability and safety during the lifting process. This structure effectively prevents the risk of the table top dropping or falling, and ensures the safety of the experimenters and equipment. Among them, the structure of the lifting assembly and the drive assembly takes maintainability into consideration. The adaptation setting of the clip and the opening facilitates the inspection and replacement of worn parts; the modular setting of the drive assembly makes it simple and quick to repair and replace the drive parts. This reduces maintenance costs and extends the service life of the equipment.

[0051] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
