Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and more specifically, to a constant temperature oscillating water bath with an adjustable mesh support frame. Background Technology

[0002] Thermostatic shaking baths are commonly used equipment in experimental fields such as biology and chemistry. By controlling the water temperature and supplementing it with shaking function, they provide a stable temperature environment and uniform reaction conditions for experimental samples. Thermostatic shaking baths on the market are equipped with internal support frames, which can be used to support the experimental containers.

[0003] Utility model patent CN211837716U discloses a water bath constant temperature oscillator, including an oscillator body and a sealing cover. The oscillator body has a water tank inside, and a heating device is fixedly installed at the bottom of the water tank. An oscillating device is fixedly installed at the end of the oscillator body away from the heating device. Several support plates are fixedly installed at the output end of the oscillating device. A support platform is embedded in the water tank, and several connecting plates are fixedly installed on the support platform. Several rectangular slots for use with the support plates are opened at the upper end of the sealing cover. A switch is fixedly installed at the end of the oscillator body away from the sealing cover, and an indicator light is fixedly installed at the end of the oscillator body away from the switch. This utility model controls the oscillation speed and time of the oscillator through a speed controller and a temperature controller, respectively.

[0004] While the aforementioned technical solutions offer corresponding advantages, existing support frames for constant-temperature shaking water baths also have some shortcomings in use. For example, traditional support frames are mostly fixed structures with adjustable grid spacing, making them difficult to adapt to different sizes of experimental containers, such as test tubes, beakers, and petri dishes. This results in unstable container placement, making them prone to tipping or collisions, affecting experimental safety and accuracy. Some adjustable support frames have cumbersome adjustment methods, requiring manual adjustment of each grid unit, leading to low operational efficiency and limited adjustment range, failing to meet diverse experimental needs. Therefore, we propose a constant-temperature shaking water bath with an adjustable grid support frame. Utility Model Content

[0005] The purpose of this invention is to provide a constant temperature oscillating water tank with an adjustable mesh support frame to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A constant-temperature oscillating water bath with an adjustable grid support frame includes a constant-temperature oscillating water bath body and a tank body disposed within the constant-temperature oscillating water bath body. A grid support frame is disposed within the tank body. The two sides of the grid support frame rest on the top surface of the constant-temperature oscillating water bath body. A perforated plate is fixedly installed at the bottom position of the grid support frame. Two upper and lower grid limiting components are fixedly installed between the left and right side rods of the grid support frame. The grid limiting components include two side fixing strips fixedly installed on the corresponding grid support frames. Multiple tension springs are detachably installed between the two corresponding side fixing strips. The tension springs are covered with an outer elastic sleeve. The projections of the upper tension spring and the lower tension spring are perpendicular to each other.

[0008] Preferably, the perforated plate has a perforated plate structure, and the tension springs at the top and bottom together form a mesh;

[0009] This setup allows for the use of a grid of tension springs to limit the movement of test tubes, beakers, petri dishes, and other similar items.

[0010] Preferably, the side fixing strip is provided with a plurality of locking holes arranged along the length direction of the side fixing strip, and the end of the tension spring is engaged with the locking holes;

[0011] This setting allows for the installation, removal, and replacement of tension springs.

[0012] Preferably, upper locking blocks are fixedly installed on the top left and right sides of the main body of the constant temperature oscillating water tank, and locking sleeves are fixedly installed on both sides of the grid support frame, with the locking sleeves fitted onto the upper locking blocks;

[0013] Preferably, positioning protrusions are fixedly installed on the top left and right sides of the constant temperature oscillating water tank body, a slot is provided between the upper locking block and the positioning protrusion, and the side plate of the sleeve is located in the slot and engages with the slot.

[0014] The above two settings facilitate the loading and unloading of the grid support frame.

[0015] Preferably, a positioning sleeve is fixedly installed on the side of the sleeve, and the positioning sleeve is fitted onto the positioning protrusion;

[0016] Preferably, the positioning sleeve is provided with a positioning hole, and the positioning protrusion is inserted into the positioning hole;

[0017] The above two settings can be used to position the grid support frame during installation.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model uses a grid limiting component with two perpendicular projections at the top and bottom. It utilizes the locking holes of the side fixing strips and the locking mechanism of the tension springs. Due to the elasticity of the tension springs, different grid sizes can be formed as the adjacent tension springs deform at corresponding locations. Containers are inserted through the mesh holes and pressed against the mesh plate, achieving adaptable support for different experimental containers such as test tubes and beakers. The adjacent upper and lower tension springs press against the four sides of the container for limiting, making the grid adjustable and limiting the container. This solves the problem of poor adaptability of traditional fixed support frames and improves the versatility of the equipment.

[0020] 2. This utility model utilizes a grid support frame that is engaged with the upper block of the constant temperature shaking water tank body via a snap-fit ​​sleeve. The positioning sleeve and positioning protrusion cooperate for positioning, making installation and removal convenient. Furthermore, the outer elastic sleeve outside the tension spring can buffer the shock of vibration, preventing the container from tipping over and breaking. This solves the problems of cumbersome operation and insufficient stability of some adjustable support frames, thereby improving operational efficiency and experimental safety.

[0021] 3. This utility model utilizes a perforated plate in conjunction with a mesh-like tension spring to provide bottom support for the container and enhance the fixing effect through the elastic limit of the tension spring, adapting to the shaking during the constant temperature oscillation process, ensuring the experimental container is placed stably, and achieving the effect of ensuring the accuracy of the experiment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Please see Figures 1-5 This utility model provides a technical solution: a constant temperature oscillating water tank with an adjustable mesh support frame, including a constant temperature oscillating water tank body 1 and a tank 10 disposed within the constant temperature oscillating water tank body 1. A mesh support frame 2 is disposed within the tank 10. The two sides of the mesh support frame 2 rest on the top surface of the constant temperature oscillating water tank body 1. A perforated plate 23 is fixedly installed at the bottom position of the mesh support frame 2. Two upper and lower mesh limiting components 3 are fixedly installed between the left and right side rods of the mesh support frame 2. The mesh limiting components 3 are located above the perforated plate 23. The mesh limiting components 3 include two side fixing strips 30 fixedly installed on the corresponding mesh support frames 2. The two corresponding side fixing strips 30 are detachably installed. There are multiple tension springs 33, and each tension spring 33 is wrapped with an outer elastic sleeve 32. The projections of the upper tension spring 33 and the lower tension spring 33 are perpendicular to each other. The mesh plate 23 is a mesh-like plate structure. The upper and lower tension springs 33 together form a mesh. The mesh plate 23 can support the bottom of containers such as test tubes, beakers, and petri dishes. Since the tension springs 33 can deform, as the tension springs 33 deform to both sides, the space of the corresponding middle mesh part changes. At this time, containers such as test tubes, beakers, and petri dishes can be placed into the corresponding space. The upper and lower tension springs 33 respectively abut against the four sides of the container, which can limit the position of the containers such as test tubes, beakers, and petri dishes.

[0033] like Figure 4 and Figure 5 As shown, the side fixing strip 30 is provided with a plurality of locking holes 31 arranged along the length direction of the side fixing strip 30. The end of the tension spring 33 is engaged with the locking holes 31 to facilitate loading, unloading and replacement operations.

[0034] like Figure 1 and Figure 2As shown, upper locking blocks 11 are fixedly installed on the top left and right sides of the main body 1 of the constant temperature oscillating water tank, and locking sleeves 20 are fixedly installed on both sides of the grid support frame 2. The locking sleeves 20 are fitted onto the upper locking blocks 11. Positioning protrusions 12 are fixedly installed on the top left and right sides of the main body 1 of the constant temperature oscillating water tank, and a slot 13 is provided between the upper locking block 11 and the positioning protrusion 12. The side plate of the locking sleeve 20 is located in the slot 13 and engages with the slot 13, which facilitates the loading and unloading of the grid support frame 2.

[0035] like Figure 1 and Figure 2 As shown, a positioning sleeve 21 is fixedly installed on the side of the sleeve 20, and the positioning sleeve 21 is fitted onto the positioning protrusion 12; a positioning hole 22 is provided inside the positioning sleeve 21, and the positioning protrusion 12 and the positioning hole 22 are inserted and matched, so that the grid support frame 2 is easy to install and remove and is installed accurately, achieving the effect of easy disassembly and positioning.

[0036] When using the constant temperature oscillating water tank with adjustable grid support frame of this utility model, align the sleeves 20 on both sides of the grid support frame 2 with the upper locking block 11 of the constant temperature oscillating water tank body 1, fit the positioning hole 22 of the positioning sleeve 21 onto the positioning protrusion 12, and insert the side plate of the sleeve 20 into the slot 13 to complete the installation.

[0037] Next, the tension spring 33 is pulled to both sides to deform it. At this time, the size of the grid space formed by the upper and lower tension springs 33 changes. Containers such as test tubes, beakers, and petri dishes are inserted along the grid space. The outer elastic sleeve 32 of the deformed tension spring 33 is used to press against the four sides of the container to achieve the fixing operation.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
