[0001] This application belongs to the field of screen printing equipment technology, and more specifically, relates to a laboratory water bath shaking device. Background Technology

[0002] In the laboratory testing process, some of the pre-experimental treatments involve a water bath process. Usually, in order to ensure a full reaction, the materials in the water bath need to be shaken evenly during the water bath process. In this case, staff need to perform timed actions.

[0003] In practice, workers need to first lift the container containing the material out of the water, then shake it manually to mix it, and finally put it back into the water bath. However, if there are many containers in the water bath at the same time, workers need to operate the containers frequently, which greatly increases their workload. Utility Model Content

The top end of the fixing rod abuts against the container to be water bathed, so that the container is fixed to the fixing ring.

[0010] In one possible implementation, the fixing rod includes a threaded section and a rubber section, the threaded section being threaded onto the fixing ring, and the rubber section being disposed at the top end of the threaded section and pressed against the container to be water-bathed.

[0024] The laboratory water bath shaking device provided in this application will now be described.

[0025] Please refer to the following: Figure 1 and Figure 2The laboratory water bath shaking device includes a base 1, multiple hangers 2, multiple fixing rings 3, and multiple shaking mechanisms 4. The base 1 has a cross-shaped mounting bracket 101 on top. The hangers 2 are mounted on the mounting bracket 101 and include a sliding rod 201 that slides vertically. Multiple fixing rings 3 correspond one-to-one with the hangers 2 and are located at the bottom of their respective hangers. The fixing rings 3 are used to fix containers to be bathed in water, and the containers can be bathed by sliding the sliding rod 201 downwards or by sliding the sliding rod 201 upwards. Multiple shaking mechanisms 4 correspond one-to-one with the hangers 2 and are located between their respective sliding plates and fixing rings 3. The shaking mechanisms 4 are used to shake the liquid in the containers fixed to the fixing rings 3.

[0026] The beneficial effects of the laboratory water bath shaking device provided in this embodiment are as follows: Compared with the prior art, the laboratory water bath shaking device provided in this embodiment constitutes a complete water bath shaking system through the arrangement of a base 1, a mounting bracket 101, a hanging bracket 2, a fixing ring 3, and a shaking mechanism 4. The base 1 provides stable support, and the cross-shaped mounting bracket 101 facilitates the installation and layout of multiple hanging brackets 2. The sliding rod 201 on the hanging bracket 2 can slide vertically, which facilitates the control of the up and down position of the container to be water bathed, thereby realizing the water bath and release operations. The fixing ring 3 can firmly fix the container to be water bathed, ensuring that the container will not fall off during the water bath and shaking process. The shaking mechanism 4 can shake the liquid in the container fixed on the fixing ring 3. The entire device has a simple structure. The operator only needs to fix the container on the fixing ring 3 and realize the water bath and shaking operations by sliding the sliding rod 201, without complicated operation procedures. The shaking mechanism 4 allows the liquid in the container to be thoroughly shaken. Compared with manual shaking, it can mix the materials in the container more evenly, which is beneficial to improving the accuracy and repeatability of the experiment.

[0027] like Figure 2 and Figure 3 As shown, the hanger 2 includes a hanging ring 202, a hanging plate 203, a sliding rod 201, and a first motor 204. The hanging ring 202 is fixed to the horizontal part of the mounting bracket 101. The hanging plate 203 is disposed on the hanging ring 202, and the scraper is provided with a clearance hole. The sliding rod 201 is inserted into the clearance hole and has a rack and pinion structure. The first motor 204 is disposed on the hanging plate 203, and the power output end of the first motor 204 is provided with a drive gear 205, which meshes with the sliding rod 201.

[0028] The hanger 2 is equipped with a first motor 204, a drive gear 205, and a rack and pinion structure slide rod 201. The first motor 204 drives the drive gear 205 to rotate, which meshes with the rack on the slide rod 201, thereby causing the slide rod 201 to slide up and down in the vertical direction. This realizes the automatic lifting and lowering of the container to be bathed in water, eliminating the need for staff to manually lift or put the container into the water bath, further improving the convenience and automation of operation.

[0029] Compared to manual operation, motor-driven operation allows for more precise control of the lifting height of the slide bar 201, thus accurately controlling the position of the container in the water bath. This ensures that each container is bathed at the appropriate depth, guaranteeing consistent experimental conditions and improving the reliability of experimental results.

[0030] like Figure 1 A control box 206 is provided at the top of the slide bar 201. The control box 206 is electrically connected to the first motor 204. The control box 206 is used for timing and controlling the opening and closing of the first motor 204 to automatically realize the timed lifting and lowering of the water bath container. In addition, the control box 206 should also be electrically connected to the second motor 407 mentioned below to realize the automatic shaking of the water outlet container.

[0031] Specifically, the first motor 204 here is a dual-shaft motor, and the control box 206 contains a programmable timer switch and a dual-control relay module. The power supply is connected to the power input interface of the programmable timer switch to provide a suitable energy source for the entire circuit system.

[0032] The output of the programmable timer switch is connected to the control signal input of the dual-control relay module. The first set of normally open contacts of the dual-control relay module is connected to the positive power supply at one end and to the reverse rotation terminal of the dual-axis motor's lifting shaft at the other end. Similarly, the second set of normally open contacts of the dual-control relay module is connected to the positive power supply at one end and to the forward rotation terminal of the dual-axis motor's lifting shaft at the other end. The common terminal of the dual-axis motor's lifting shaft is connected to the negative power supply.

[0033] With this connection, when the timer switch closes the first set of normally open contacts, current flows from the positive terminal of the power supply, through the first set of normally open contacts, into the reverse terminal of the dual-axis motor's lifting shaft, and then returns to the negative terminal of the power supply through the common terminal, driving the lifting shaft to reverse and causing the container to descend into the water bath. When the second set of normally open contacts closes, the current path changes, driving the lifting shaft to rotate forward and causing the container to move upward.

[0034] The third set of normally open contacts of the dual-control relay module is connected to the positive terminal of the power supply on one end and to the second motor 407 on the other end. The other end of the second motor 407 is connected to the negative terminal of the power supply. When the timer switch closes the third set of normally open contacts, current flows through the contacts to drive the dual-axis motor's shaking shaft, causing the container to shake evenly. Simultaneously, the water bath time and shaking time can be preset using a programmable timer switch, achieving a timed automatic cycle of water bath to shaking and back to water bath.

[0035] Here, the water bath time is preset to 15 minutes, and the lifting and shaking time is preset to 3 minutes, with 1 minute used for lifting and 2 minutes for shaking. During the first minute, the timer switch closes the first set of normally open contacts of the dual-control relay module, the dual-axis motor's lifting shaft reverses, and the container descends into the water bath. Then, the timer switch opens the first set of normally open contacts of the dual-control relay module, and the water bath continues from minute 2 to minute 16. At minute 17, the timer switch opens the first set of normally open contacts of the dual-control relay module and closes the second set of normally open contacts, the lifting shaft rotates forward, and the container rises away from the water surface. From minute 18 to minute 19, the timer switch opens the second set of normally open contacts of the dual-control relay module and simultaneously closes the third set of normally open contacts, starting the second motor 407 and shaking the container. At minute 20, the timer switch opens the third set of normally open contacts of the dual-control relay module and closes the first set of normally open contacts, the lifting shaft reverses, and the container re-enters the water bath, starting the next cycle.

[0036] like Figure 2 and Figure 3 As shown, the horizontal section of the mounting bracket 101 has a polygonal cross-section, and the inner hole of the hanging ring 202 is adapted to the horizontal section of the mounting bracket 101. The horizontal section of the mounting bracket 101 is inserted into the inner hole of the ring, and the ring is provided with multiple fixing bolts 207, which are tightened against the horizontal section of the mounting bracket 101.

[0037] This design allows the hanger 2 to be easily installed on the mounting frame 101, and its position on the mounting frame 101 can be adjusted according to experimental needs. The polygonal horizontal portion of the mounting frame 101, the matching inner hole of the hanging ring 202, and the fixing bolts 207 ensure a more secure connection between the hanger 2 and the mounting frame 101, enabling it to withstand greater external forces. During the lifting, lowering, and shaking of the container, the hanger 2 will not shake or loosen, thus improving the structural stability of the entire device and ensuring the smooth progress of the experiment.

[0038] like Figure 1 As shown, multiple fixing rods 301 are screwed onto the fixing ring 3. The top of the fixing rod 301 can move closer to or further away from the axis of the fixing ring 3 due to the rotation of the fixing rod 301. The top of the fixing rod 301 abuts against the container with water bath so that the container is fixed on the fixing ring 3.

[0039] Multiple fixing rods 301 are screwed onto the fixing ring 3. By rotating the fixing rods 301, the tips of the fixing rods 301 can be moved closer to or further away from the axis of the fixing ring 3, thereby locking or loosening the container to be water bathed. This method allows for flexible adjustment according to containers of different sizes and shapes, ensuring that the container can be firmly fixed to the fixing ring 3. Because the fixing rods 301 can be adjusted to accommodate containers of different sizes, this device has a wider range of applications and can meet the water bath mixing needs of various laboratory containers, thus improving the versatility of the device.

[0040] like Figure 5 As shown, the fixing rod 301 includes a threaded section 302 and a rubber section 303. The threaded section 302 is threaded onto the fixing ring 3, and the rubber section 303 is located at the top of the threaded section 302, pressing against the container to be water-bathed. The rubber section 303 prevents the fixing rod 301 from damaging the outer wall of the container when fixing it. For some glass containers, the elasticity of the rubber section 303 can act as a buffer, preventing the fixing rod 301 from being over-tightened and causing the container to break, thus protecting the experimental container and reducing experimental costs.

[0041] Furthermore, the surface of rubber segment 303 possesses a certain degree of friction, allowing it to better adhere to the outer wall of the container and increasing its stability. During water bath and shaking processes, even if the container is subjected to certain external forces, the friction between rubber segment 303 and the container prevents relative sliding, ensuring the smooth progress of the experiment. Combination Figure 2 , Figure 3 As shown, the shaking mechanism 4 includes a shaking plate 401, a shaking slide plate 402, and a driving assembly. The shaking plate 401 is located at the bottom of the slide rod 201. The shaking slide plate 402 is slidably mounted on the shaking plate 401. A shaking rod 409 is located at the bottom of the shaking slide plate 402, and a fixing ring 3 is connected to the corresponding shaking rod 409. The driving assembly is located on the shaking plate 401 and is connected to the shaking slide plate 402. The driving assembly is used to drive the shaking slide plate 402 to reciprocate.

[0042] When the shaking slide plate 402 reciprocates, it drives the shaking rod 409 to move the fixed ring 3 and the container together, thereby achieving the mixing of the liquid in the container. This mixing method allows the liquid in the container to be subjected to forces in multiple directions, resulting in a more uniform mixing effect. For example, in experiments that require rapid mixing of two or more liquids, this shaking mechanism 4 can thoroughly mix the liquid in a shorter time, improving experimental efficiency.

[0043] Meanwhile, the components of the shaking mechanism 4 are rationally arranged, compact in structure, and occupy little space. The shaking slide plate 402 slides on the shaking plate 401, and the sliding stability of the shaking slide plate 402 is ensured by the cooperation of the guide rod 403 and the guide groove. At the same time, the setting of the drive component does not occupy too much space, so that the entire device can achieve efficient shaking function within a limited space.

[0044] In this embodiment, the bottom of the shaking plate 401 is provided with two guide rods 403, which are arranged at intervals and have guide grooves on opposite surfaces. The two sides of the shaking plate 402 are provided with guide blocks 404, which are inserted into the guide grooves.

[0045] The guide rod 403 at the bottom of the shaking plate 401 and the guide blocks 404 on both sides of the shaking slide plate 402 cooperate to ensure that the shaking slide plate 402 can accurately reciprocate along the direction of the guide rod 403 during the sliding process, without wobbling or deviation. This ensures that the shaking slide plate 402 can stably drive the fixed ring 3 and the container to perform the shaking operation, improving the accuracy and reliability of shaking.

[0046] like Figure 4 As shown, the drive assembly includes a reset plate 405, a reset spring 406, a second motor 407, and a shaking cam 408. The reset plate 405 is fixed to the bottom of the shaking plate 401, and the reset plate 405 and the shaking slide plate 402 are arranged at intervals. The reset spring 406 is located between the reset plate 405 and the shaking slide plate 402. When the reset spring 406 is in its natural state, a portion of the shaking slide plate 402 extends to the outside of the shaking plate 401. The second motor 407 is located on the shaking plate 401. The shaking cam 408 is located at the power output end of the second motor 407. The shaking cam 408 can push the shaking slide plate 402 towards the reset plate 405 due to rotation, and the shaking cam 408 can release the pushing of the shaking slide plate 402 due to rotation.

[0047] In the drive assembly, the second motor 407 drives the shaking cam 408 to rotate. The shaking cam 408 pushes the shaking slide plate 402 towards the reset plate 405. When the shaking cam 408 rotates to a certain position, it releases the push on the shaking slide plate 402, and the shaking slide plate 402 automatically resets under the action of the reset spring 406. This realizes the automatic reciprocating motion of the shaking slide plate 402, thereby automatically shaking the liquid in the container. Simply starting the second motor 407 will automatically perform the shaking operation without manual intervention, further improving the automation level of the experiment.

[0048] By adjusting the rotational speed of the second motor 407, the rotational speed of the shaking cam 408 can be changed, thereby adjusting the reciprocating frequency of the shaking slide 402, and consequently, the shaking frequency of the liquid in the container. Simultaneously, by adjusting the elastic coefficient of the return spring 406 and the shape of the shaking cam 408, the reciprocating amplitude of the shaking slide 402 can also be adjusted to meet the requirements of different experiments regarding shaking frequency and amplitude. For example, for experiments requiring gentle shaking, the rotational speed of the second motor 407 can be reduced to decrease the shaking amplitude; for experiments requiring vigorous shaking, the rotational speed of the second motor 407 can be increased to increase the shaking amplitude.

[0049] In this embodiment, in order to protect the shaking mechanism 4 and prevent the water in the water bath from damaging the second motor 407, a protective box is fixed at the bottom of the slide bar 201, and the protective box covers the shaking mechanism 4.

[0050] Multiple L-shaped connecting rods 410 are provided between the shaking rod 409 and the fixing ring 3, and the connecting rods 410 are evenly arranged along the circumference of the shaking rod 409. The setting of the connecting rods 410 can make the fixing ring 3 more firmly connected to the shaking rod 409, and can evenly transmit the shaking force during the shaking process, preventing the fixing ring 3 from tilting or shaking, thus improving the structural stability of the entire shaking mechanism 4.

[0051] Finally, a clearance rod 208 is provided at the bottom of the slide rod 201. The clearance rod 208 is L-shaped, with the horizontal part of the clearance rod 208 fixedly connected to the slide rod 201, and the vertical part of the clearance rod 208 fixed to the top of the shaking plate 401. The clearance rod 208 allows the base 1 to be fixed next to the water bath, with the fixing ring 3 located above the water bath, thus facilitating water bathing of the container on the fixing ring 3.

[0052] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
