Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and more specifically, to a constant temperature mixer. Background Technology

[0002] A homogenizer is a widely used laboratory device whose main function is to thoroughly mix, stir, and uniformly disperse sample solutions to ensure the accuracy and reliability of experimental results. In practical applications, the homogenization process of some media requires a long time due to their physical or chemical properties, which affects experimental efficiency to some extent. By increasing the temperature of the medium, the reaction rate can be significantly accelerated, thereby shortening the homogenization time and improving experimental efficiency.

[0003] Chinese patent CN 221182657 U discloses a constant temperature mixer, which integrates a test tube cover mechanism on the main unit for fixing test tubes. A limiting plate is provided at the top of the guide rod. When installing test tubes, the operator needs to pull the cover 32 to the position defined by the limiting plate to provide space for the test tubes. However, the operator must manually hold the test tubes and insert them into the bottom of the cover 32 for placement. During this process, the presence of the cover 32 can obstruct the operator's view to some extent, increasing the difficulty and uncertainty of test tube placement and affecting the convenience and efficiency of the operation. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a constant temperature mixer.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A constant temperature mixer includes a main body, an mounting plate on the top of the main body, a connector box fixedly connected to the mounting plate, a plurality of test tubes inserted into the connector box, two guide rods on the main body, the two guide rods being respectively located on both sides of the connector box, a top cover being rotatably connected between the two guide rods, a sponge test tube cap being provided at the bottom of the top cover, and a support member being provided on the guide rods.

[0007] Furthermore, the guide rod is provided with a rotating shaft, and a top cover is rotatably connected between the two rotating shafts.

Detailed Implementation

[0021] 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 a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0022] like Figures 1-5 As shown, a constant temperature mixer includes a main body 100, an mounting plate 101 is mounted on the top of the main body, a plug box 102 is fixedly connected to the mounting plate, a plurality of test tubes 103 are inserted into the plug box, and the main body can drive the test tubes to shake. The above technical features are all existing technologies, such as the MK-3000 constant temperature mixer produced by Hangzhou Aosheng Instrument Co., Ltd.

[0023] In at least one embodiment, the main body is provided with two guide rods 1, which are respectively located on both sides of the plug-in box. A top cover 2 is rotatably connected between the two guide rods, and a sponge test tube cover 3 is provided at the bottom of the top cover. Supporting components are provided on the guide rods.

[0024] Furthermore, the guide rod is equipped with a rotating shaft 11, and a top cover is rotatably connected between the two rotating shafts. The design of the rotating shaft allows the top cover to rotate around it, facilitating the placement and removal of test tubes by the operator.

[0025] In a more detailed design, the support member restricts the rotation of the top cover around the pivot axis. This design effectively limits the rotation range of the top cover, ensuring it can be stably fixed in the desired position when not in use, thus improving operational convenience and safety.

[0026] In at least one embodiment, the support member includes a rotating plate 4 and a fixed plate 5. The rotating plate is rotatably connected to the guide rod, and the fixed plate is fixedly connected to the guide rod. The rotating plate is located above the rotating shaft, and the fixed plate is located below the rotating shaft. An adjusting bolt 6 is threadedly connected to the fixed plate.

[0027] Furthermore, the rotating plate includes a rotating ring 41, with a mounting hole 42 formed in the center of the rotating ring, and an upper limit plate 43 formed on one side of the rotating ring. The design of the rotating ring allows the rotating plate to rotate easily around the guide rod, while the design of the upper limit plate effectively restricts the upward rotation of the top cover, ensuring the stability of the top cover.

[0028] In a more detailed design, the guide rod is provided with an external thread, and a rotating plate is threadedly connected to this external thread. The external thread of the guide rod mates with a mounting hole, allowing the rotating plate to achieve a rotatable threaded connection with the guide rod via the mounting hole.

[0029] Furthermore, the fixing plate includes a fixing ring 51, with a positioning hole 52 formed in the middle of the fixing ring, and a lower connecting plate 53 formed on one side of the positioning hole. The lower connecting plate has a threaded hole 54. The fixing ring can accommodate the guide rod, and the fixing plate is fixedly connected to the guide rod by argon arc welding at multiple spot welds on the fixing ring. When the upper cover rotates to a horizontal position, the sponge test tube cap contacts the top of the test tube, the lower connecting plate adheres to the bottom of the upper cover, and the upper limit plate rotates to the top of the upper cover to restrict the rotation of the upper cover around the axis. The cooperation of the lower connecting plate and the upper limit plate effectively restricts the rotation of the upper cover, ensuring the stability of the upper cover in a horizontal position.

[0030] The solution is further refined, and the threaded hole is internally threaded with an adjusting bolt.

[0031] To test the operation, confirm that the main body, mounting plate, connector box, and test tubes of the thermostatic mixer are all properly installed and in normal working order. When placing or removing test tubes, first rotate the rotating plate to rotate the upper limit plate 180°, thus releasing the rotation restriction on the top cover. Next, rotate the top cover around the axis to open it to a suitable position. After opening the top cover, test tubes can be easily placed or removed. Afterward, rotate the top cover back to the horizontal position so that the sponge test tube cap contacts the top of the test tube. Rotate the rotating plate again to rotate the upper limit plate to the top of the top cover, thus restricting the top cover's rotation around the axis.

[0032] If necessary, the upward tilt angle of the top cover can be adjusted by turning the adjusting screw for better observation or handling of the test tubes.

[0033] 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 descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
