Description

Technical Field

[0001] This utility model relates to the field of experimental tool technology, and more specifically, to an adjustable-angle thin experimental plate support frame. Background Technology

[0002] In biological experiments and molecular biology research, 96-well plates and PCR multi-well plates are commonly used experimental tools, widely applied in cell culture, enzyme-linked immunosorbent assay (ELISA), polymerase chain reaction (PCR), and other experimental procedures. However, when performing these experiments, researchers often face a challenging problem: how to conveniently observe the status of each well in the plate to ensure that the required reagents or samples have been correctly added to each well.

[0003] Traditional experimental racks or support devices are mostly simple in design, providing only basic support functions and unable to adjust the angle according to experimental needs. When researchers need to observe the bottom of the well plate, they often have to bend over or tilt their bodies to get a better view. This posture is not only uncomfortable, but may also cause researchers to maintain poor posture for a long time, increasing physical strain.

[0004] Furthermore, for experiments requiring precise observation of the liquid within the wells, such as confirming that reagents have been added to each well and that the liquid is evenly distributed, traditional lab racks cannot provide sufficient lighting. Researchers typically need to use additional lighting equipment such as flashlights or desk lamps, which not only increases the complexity of the experiment but can also create shadows or reflections due to improper placement or angle of the lighting equipment, affecting observation. This is especially true for highly precise experiments such as PCR, where the state of the liquid within the wells is crucial to the results. Failure to clearly observe the state of each well can lead to experimental errors or inaccurate results. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable-angle fine experimental plate support frame to solve the problem mentioned in the background art that traditional experimental frames cannot provide sufficient lighting support for certain experiments that require precise observation of the liquid in the well plate, such as confirming whether reagents have been added to each well and whether the liquid is evenly distributed.

[0006] To achieve the above objectives, this utility model provides an adjustable-angle thin experimental plate support frame, including a base, side plates installed on both sides of the top center of the base, a support plate installed between the two side plates, and both ends of the support plate being rotatably connected to the two side plates respectively by pins, and the outer end of each pin being locked and positioned by a locking assembly. The top of the support plate is provided with a support groove, and a lamp plate is installed at the bottom of the support groove. Several lamp beads are installed on the top surface of the lamp plate.

[0007] Preferably, a transparent glass is installed above the lamp panel, and several lamp beads are located below the transparent glass. A circuit channel is provided on one side of the support plate, and a wire hole is provided on the surface of the side plate. The circuit of the lamp panel passes through the circuit channel and the wire hole in sequence and is then connected to an external power supply.

[0008] Preferably, a transverse positioning cylinder is fixedly installed on the side plate, and the outer end of the pin is inserted into the positioning cylinder for engagement.

[0009] Preferably, the outer wall of the positioning cylinder is provided with external threads, the locking assembly includes a threaded sleeve, the inner wall of the threaded sleeve is provided with internal threads, the threaded sleeve is threadedly connected to the outer side of the outer end of the positioning cylinder, and a pressure pad is installed on the inner wall of one end of the threaded sleeve, the pressure pad pressing and positioning the outer end of the pin.

[0010] Preferably, a knob is mounted on the outside of the threaded sleeve.

[0011] Preferably, the LED beads are arranged at equal intervals.

[0012] Preferably, the compression pad is made of sponge material.

[0013] Preferably, the outer wall of the knob is provided with anti-slip stripes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this adjustable-angle microplate support frame, the support plate is rotatably connected to the side plate via a pin and locked in place by a locking assembly, allowing for flexible adjustment of the support plate angle. Experimenters can easily adjust the angle of the support plate according to experimental needs, placing the perforated plate in the optimal observation position without bending over or tilting their bodies, greatly improving the comfort and convenience of the experiment.

[0016] A light panel is installed at the bottom of the support slot, with several LEDs arranged at equal intervals on the panel to provide uniform and soft light. The lighting system is directly integrated into the support frame, eliminating the need for additional lighting equipment such as flashlights or desk lamps, simplifying the experimental process and reducing the space occupied. The transparent glass protects the light panel while ensuring good light transmission, allowing researchers to clearly observe the condition of each hole in the perforated plate.

[0017] The locking assembly uses a threaded connection between a threaded sleeve and a positioning cylinder. By tightening the threaded sleeve, the pressure pad is pressed against the pin, achieving a stable lock on the support plate. The knob facilitates the operation of the locking assembly, and the anti-slip stripe design increases the grip and anti-slip properties of the knob, ensuring the reliability and stability of the locking process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides an adjustable-angle support frame for a thin experimental plate, such as... Figures 1-5 As shown, the device includes a base 1, with side plates 2 installed on both sides of the top center of the base 1. A support plate 3 is installed between the two side plates 2. Both ends of the support plate 3 are rotatably connected to the two side plates 2 by pins 33, and the outer end of each pin 33 is locked and positioned by a locking assembly 4. A support groove is provided on the top of the support plate 3, and a lamp plate 31 is installed at the bottom of the support groove. Several lamp beads 311 are installed on the top surface of the lamp plate 31.

[0027] In use, side plates 2 are installed on both sides of the top of the base 1. A support plate 3 is rotatably connected between the side plates 2 via pins 33, forming a stable triangular support structure and ensuring the overall stability of the support frame. The two ends of the support plate 3 are rotatably connected to the side plates 2 via pins 33, allowing the support plate 3 to be adjusted in angle according to experimental needs, making operation simple and highly flexible. The outer end of the pins 33 is locked in place by a locking assembly 4, effectively preventing the support plate 3 from shaking or shifting after angle adjustment, ensuring safety and reliability during the experiment. The lamp plate 31 installed inside the support plate 3 integrates lighting functions, providing uniform and soft light for the experiment, improving the observation effect.

[0028] In this embodiment, a transparent glass 32 is installed above the lamp board 31, and several LED beads 311 are located below the transparent glass 32. The transparent glass protects the lamp board while ensuring light transmission, allowing the experimenter to clearly observe the state of each hole in the perforated plate. A wiring channel 34 is provided on one side of the support plate 3, and wire holes 21 are provided on the surface of the side plate 2. The wiring of the lamp board 31 passes through the wiring channel 34 and the wire holes 21 in sequence before being connected to an external power supply. The evenly spaced arrangement of the LED beads 311 provides uniform and bright light for the experiment, improving the accuracy of experimental observation. The design of the wiring channel 34 and the wire holes 21 allows the wiring of the lamp board 31 to pass through the support plate 3 and the side plate 2 neatly and orderly, avoiding messy wiring and enhancing the aesthetics and practicality of the support frame. The design of the external power supply facilitates the use of the lamp board 31; simply connecting the power supply is enough to light up the LED beads 311, making operation simple. Preferably, the power supply can also be provided with a knob for adjusting the brightness of the lamp beads 311, so that The brightness of the lamp beads 311 can be changed as needed.

[0029] Specifically, a transverse positioning cylinder 22 is fixedly installed on the side plate 2. The outer end of the pin 33 is inserted into the positioning cylinder 22 for engagement, and the outer end of the pin 33 extends to the outer side of the positioning cylinder 22. The positioning cylinder 22 ensures the stability and accuracy of the support plate 3 during rotation. The engagement between the pin 33 and the positioning cylinder 22 makes the installation and disassembly of the support plate 3 more convenient and quick, improving the maintainability and expandability of the support frame.

[0030] Furthermore, the outer wall of the positioning cylinder 22 is provided with external threads, and the locking assembly 4 includes a threaded sleeve 41. The inner wall of the threaded sleeve 41 is provided with internal threads. The threaded sleeve 41 is threaded onto the outer side of the outer end of the positioning cylinder 22. A pressure pad 43 is installed on the inner wall of one end of the threaded sleeve 41. By tightening the threaded sleeve 41, the pressure pad 43 presses against and positions the outer end of the pin 33. The threaded connection between the threaded sleeve 41 and the positioning cylinder 22 achieves reliable fixation of the locking assembly 4. By rotating the threaded sleeve 41, the pressure force of the pressure pad 43 on the pin 33 can be easily adjusted, thereby achieving precise locking of the angle of the support plate 3. The design of the pressure pad 43 increases the contact area between the locking assembly 4 and the pin 33, improving the stability and reliability of the locking.

[0031] Furthermore, a knob 42 is mounted on the outside of the threaded sleeve 41. The design of the knob 42 makes the rotation operation of the threaded sleeve 41 more convenient and quick. The experimenter only needs to gently rotate the knob 42 to adjust and lock the angle of the support plate 3, which improves the convenience and efficiency of the experimental operation.

[0032] Furthermore, the LED beads 311 are arranged at equal intervals. This equal-interval arrangement of the LED beads 311 ensures that each area on the experimental board receives light of the same brightness, avoiding the impact of uneven light distribution on experimental observation and improving the accuracy and reliability of the experiment.

[0033] Furthermore, the clamping pad 43 is made of sponge material. The sponge material has good elasticity and softness, allowing the clamping pad 43 to fit tightly against the outer end of the pin 33, increasing the friction between the locking assembly 4 and the pin 33, and improving the stability and reliability of the locking. At the same time, the sponge material also has certain shock-absorbing properties, which can reduce the vibration and noise of the support plate 3 during rotation.

[0034] Furthermore, the outer wall of the knob 42 is provided with anti-slip stripes. The anti-slip stripe design increases the grip and anti-slip properties of the knob 42, allowing the experimenter to more stably control the force and direction when rotating the knob 42, avoiding operational errors caused by slipping or insufficient force.

[0035] In use, the adjustable-angle fine experimental plate support frame of this utility model consists of a base 1, side plates 2, and a support plate 3, forming a stable triangular support structure. The cell culture plates or PCR plates used in the experiment are placed and positioned within the support groove. The base 1 provides a stable support foundation, and the side plates 2 are rotatably connected to the support plate 3 via pins 33, ensuring the overall stability of the support frame.

[0036] The experimenter can manually adjust the angle of the support plate 3 by rotating it according to the experimental requirements. After adjusting to the required angle, the experimenter uses the locking assembly 4 to lock the support plate 3 to prevent it from shaking or shifting during the experiment. By rotating the threaded sleeve 41, the experimenter moves the threaded sleeve 41 towards the pin 33 outside the positioning cylinder, thereby easily adjusting the clamping force of the clamping pad 43 on the pin 33. When the clamping pad 43 is tightly fitted against the outer end of the pin 33, the support plate 3 is firmly locked at the required angle.

[0037] The wiring of the lamp board 31 passes through the wiring channel 34 on one side of the support plate 3 and the wire hole 21 on the surface of the side plate 2, and is connected to an external power supply. Simply connecting the power supply is enough to light the lamp beads 311, making operation simple. A transparent glass 32 covers the lamp board 31, protecting the lamp beads 311 while ensuring light transmission and improving the observation effect of the experiment.
