Description

Technical Field

[0001] This utility model relates to the field of constant temperature oscillators, and more specifically, to a reciprocating water bath constant temperature oscillator. Background Technology

[0002] A water bath constant temperature shaker is an experimental device that combines temperature control and oscillation functions. It is mainly used in laboratories in fields such as chemistry, physics, biology, and pharmaceuticals, especially in situations requiring temperature control and oscillation mixing. The water bath constant temperature shaker provides a uniform temperature environment through a water bath, while simultaneously using oscillation functions (such as horizontal or vertical oscillation) to mix samples. Heating the water to the required constant temperature can assist in the processing of pharmaceuticals.

[0003] However, most water bath constant temperature oscillators currently have the following problems:

[0004] Existing water bath constant temperature shakers mostly have through holes inside the equipment to place test tubes containing reagents for processing. However, different reagents require different amounts to be processed. If there is a large amount of reagent, a larger test tube is needed, which cannot be placed in the small through holes. If the test tube is too small, it is easy for it to fall off. It is also inconvenient to limit the placement of test tubes of different sizes. At the same time, most existing equipment uses a vibration motor to vibrate the material for processing. However, the vibration motor is used in a fixed position, the vibration range is limited, and it requires a long time to vibrate, which is inefficient and inconvenient to uniformly vibrate the material.

[0005] Therefore, we have made improvements to this by proposing a reciprocating water bath constant temperature oscillator. Utility Model Content

[0006] The purpose of this invention is to address the current problems of inconvenience in positioning test tubes of different sizes and inconvenience in uniformly reciprocating oscillation processing of materials.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A reciprocating water bath constant temperature oscillator was developed to improve the above problems.

[0009] The application is as follows:

[0010] The system includes a processing box, on which an electric heater and a temperature controller are fixedly connected. The temperature controller is connected to the electric heater via a cable. A guide rod is slidably connected to the upper limit of the processing box. A mounting plate is fixedly connected to the guide rod, and a spring is fixedly connected to the mounting plate. The other end of the spring is fixedly connected inside the processing box. A cover plate is provided on the processing box, and a first servo motor is fixedly connected to the cover plate. A push plate is fixedly connected to the output shaft of the first servo motor. A sleeve is fixedly connected to the mounting plate, and a push block is fixedly connected to the sleeve. A second servo motor is fixedly connected to the mounting plate, and a first bevel gear is fixedly connected to the output shaft of the second servo motor. The first bevel gear meshes with a second bevel gear, and a threaded rod is fixedly connected to the second bevel gear. The threaded rod is rotatably connected inside the mounting plate, and a connecting plate is threadedly connected to the threaded rod. A connecting bracket is fixedly connected to the connecting plate.

[0011] As a preferred technical solution of this application, the spring is provided in two sets, and the two sets of springs are symmetrically distributed on the left and right sides of the mounting plate, with each set of springs being equidistantly distributed on the mounting plate.

[0012] As a preferred technical solution of this application, the side end face of the mounting plate is in contact with the inner side of the processing box, and the cross-section of the push plate is teardrop-shaped.

[0013] As a preferred technical solution of this application, the side end face of the push block is inclined, the push blocks are symmetrically distributed on the left and right sides of the sleeve, and the side end face of the connecting plate is in contact with the inner side of the mounting plate.

[0014] As a preferred technical solution of this application, the second bevel gear is distributed at equal angles on the first bevel gear, and the second bevel gear corresponds one-to-one with the connecting plate through a threaded rod.

[0015] As a preferred technical solution of this application, a clamping plate is fixedly connected to the connecting frame, a protective pad is fixedly connected to the mounting plate and the clamping plate, a test tube is provided on the mounting plate, and the cross-section of the clamping plate is arc-shaped.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. Equipped with clamping plates; when clamping and limiting the test tube, the second servo motor can be activated to drive the first bevel gear to rotate. The first bevel gear can drive the threaded rod to rotate through the second bevel gear. When the threaded rod rotates, it can push the connecting plate and the connecting frame to move outward. At the same time, the clamping plates on the connecting frame, together with the protective pads, can clamp and limit test tubes of different sizes to prevent the test tubes from falling off. When disassembling the test tube, the threaded rod can be driven to rotate in the opposite direction, and the connecting plate and the connecting frame can move inward. At the same time, the clamping plates can release the clamped test tube for disassembly and installation.

[0019] 2. Equipped with a push plate; when reciprocating oscillation processing is required, the first servo motor can be turned on to drive the push plate to rotate. The longer end of the push plate can push the push block to move the sleeve. When the sleeve moves the mounting plate to the left, it can squeeze the spring on one side and pull the spring on the other side. Under the guidance of the guide rod, the mounting plate is moved smoothly. After the push plate moves past, the sleeve is unobstructed and the mounting plate is reset under the push of the spring. The rotation of the push plate can smoothly drive the mounting plate and the installed test tube to oscillate left and right, improving processing efficiency. Attached Figure Description

[0033] Example 2:

[0034] The solution in Example 1 will be further described below with reference to its specific working method.

[0035] like Figure 4 As shown, in a preferred embodiment, based on the above method, two sets of springs 6 are further provided, with the two sets of springs 6 symmetrically distributed on the left and right sides of the mounting plate 5. Each set of springs 6 is equidistantly distributed on the mounting plate 5, which can ensure that the springs 6 on both sides can smoothly push and pull the mounting plate 5 to perform left and right reciprocating oscillation.

[0036] like Figure 5 As shown, in a preferred embodiment, based on the above method, the side end face of the mounting plate 5 is in contact with the inner side of the processing box 1, and the cross-section of the push plate 9 is teardrop-shaped, which can ensure that the longer end of the teardrop-shaped push plate 9 can push the parts to move left and right.

[0038] like Figure 4As shown, in a preferred embodiment, based on the above method, the second bevel gear 14 is further distributed at equal angles on the first bevel gear 13. The second bevel gear 14 corresponds one-to-one with the connecting plate 16 through the threaded rod 15, which can ensure that the connecting plate 16 can cooperate with the connecting frame 17 and the clamping plate 18 to clamp and limit the multiple test tubes 20.

The electric heater 2 and the temperature controller 3 are turned on to heat the water to assist in the processing of the reagents. The cover plate 7 is placed on the treatment tank 1 to reset it. The first servo motor 8 is turned on to drive the push plate 9 to rotate. The longer end of the push plate 9 can push the push block 11 to move the sleeve 10. When the sleeve 10 moves the mounting plate 5 to the left, it can squeeze the spring 6 on one side and pull the spring 6 on the other side. Under the guidance of the guide rod 4, the mounting plate 5 is moved smoothly. After the push plate 9 moves past, the sleeve 10 is unobstructed and the mounting plate 5 is reset under the push of the spring 6.
