Description

Technical Field

[0001] This utility model belongs to the technical field of test tube water baths, and in particular relates to a test tube water bath device. Background Technology

[0002] In pharmaceutical research and testing, such as drug detection and experiments, heating is often required using water bath equipment, for example, placing the drug in a test tube into a water bath for heating. Traditional test tube water bath heating uses some simple test tube fixing and support devices, but after heating, removing the test tube can easily cause high-temperature burns and water droplets that may affect the environment. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a test tube water bath device.

[0004] The technical solution adopted by this utility model is as follows: a test tube water bath device, including multi-stage telescopic rotating rods and test tube positioning units; the multi-stage telescopic rotating rods are relatively distributed, and each has a mounting plate at its top, and the two mounting plates are connected by a connecting rod of a predetermined length; the device is mounted on the top of the corresponding water bath through the mounting unit at the bottom; multiple sets of test tube positioning units are provided, all slidably arranged on the connecting rods, and have positioning chambers that are open at the top and bottom, with positioning rods having a predetermined elastic deformation force at the top of the inner wall of the positioning chamber, the positioning rods extending radially along the positioning chamber to a predetermined length, and the positioning rods are arranged in a ring at intervals, abutting against the corresponding tube wall when the test tube passes through.

[0005] Furthermore, the test tube positioning unit includes a positioning block, which has a predetermined working height and working width. The positioning block is slidably disposed on the connecting rod, and a through hole is opened along the height direction to form the positioning chamber. An adaptive clamping unit is disposed in the positioning chamber and performs corresponding clamping operations in the positioning chamber.

[0006] Furthermore, the outer wall of the end of the positioning rod near the center of the positioning chamber is provided with a wiping layer of predetermined outer diameter and length, and the wiping layer forms a wiping end at the corresponding end of the positioning rod.

[0007] Furthermore, the adaptive clamping unit includes a limiting rod that moves radially through a corresponding position on the side wall of the positioning chamber; a clamping plate that is assembled on one end of the limiting rod inside the positioning chamber, and whose clamping working surface has a predetermined curvature; and a support spring that is wound around the limiting rod and located between the clamping plate and the inner wall of the positioning chamber.

[0008] Furthermore, the installation unit includes an inverted U-shaped clamp plate that is movably engaged with the top edge of the corresponding water bath. A positioning screw is movably configured on the outer side wall of the clamp plate, and the positioning screw is threadedly connected to the corresponding side wall of the clamp plate.

[0009] The beneficial effects of this utility model after adopting the above structure are as follows:

[0010] (1) The depth of the test tube submerged in the water bath can be adjusted by the multi-stage telescopic rod. After the test tube is in the water bath, the test tube positioning unit and the test tube can be raised to facilitate the draining and cooling of the test tube and to observe the color change of the internal solution.

[0011] (2) The test tube positioning unit can be used to clamp test tubes of different outer diameters, and the positioning rod with predetermined elasticity can be used to press against the side wall of the test tube for auxiliary positioning.

[0012] (3) When the water bath temperature of the test tube is not high and it needs to be removed in time, the test tube passes through the wiping end of the positioning rod to wipe the side wall of the test tube, reducing the impact of dripping water droplets on the experimental environment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0023] like Figures 1-6 As shown, a test tube water bath device includes a multi-stage telescopic rotating rod 1 and a test tube positioning unit. The multi-stage telescopic rotating rod 1 is relatively distributed, with mounting plates 3 respectively installed at its top. The two mounting plates 3 are connected by connecting rods 2 of predetermined length. The connecting rods 2 are configured as a group and distributed front and back. The device is mounted on the top of the corresponding water bath through the mounting unit at the bottom. The multi-stage telescopic rods support the test tube positioning unit above the water bath. The height can be adjusted to adjust the height of the test tubes inserted into the water bath, preventing the test tubes and other water bath containers from touching the bottom. After the water bath is completed, the test tubes can be lifted to drain water, reducing water droplets falling into the external environment.

[0024] In this embodiment, the installation unit includes an inverted U-shaped clamping plate 11, which is movably engaged with the top edge of the corresponding water bath. A positioning screw 12 is movably configured on the outer wall of the clamping plate 11. The positioning screw 12 is threadedly connected to the corresponding side wall of the clamping plate 11, thereby movably engaging the clamping plate 11 with the side wall of the water bath. An internally threaded tube is fitted on the outer wall of the clamping plate 11 at the movable through position of the positioning screw 12 to enhance the stable connection between the positioning screw 12 and the clamping plate 11. A positioning plate with a predetermined working area is configured at one end of the positioning thread located inside the clamping plate 11. By rotating the positioning screw 12, it is made to abut against the outer wall of the water bath, thereby installing the entire device on the water bath.

[0025] Based on the above embodiments, in some preferred embodiments, multiple sets of test tube positioning units are provided, all of which are slidably arranged on the connecting rod 2. When sliding, the position of the test tube positioning unit can be adjusted. For example, for a conical flask with a regular long tubular top, the distance between the two sets of positioning units needs to be adjusted during water bath to avoid collision of the lower part with a wider outer diameter.

[0026] It has a positioning chamber 4 that is open at the top and bottom. The top of the inner wall of the positioning chamber 4 is provided with a positioning rod 5 having a predetermined elastic deformation force. The positioning rod 5 extends radially along the positioning chamber 4 to a predetermined length. The positioning rods 5 are arranged in a ring at intervals and abut against the corresponding tube wall when the test tube passes through.

[0027] In this embodiment, preferably, the outer wall of the end of the positioning rod 5 near the center of the positioning chamber 4 is provided with a wiping layer 7 of a predetermined outer diameter and length. The wiping layer 7 forms a wiping end at the corresponding end of the positioning rod 5. The wiping layer 7 can be a soft material such as absorbent cotton cloth or cotton, and the thickness of the wiping layer 7 can gradually decrease in outer diameter along the length direction of the positioning rod 5, closer to the fixed end. When the water bath temperature is not high and the test tube needs to be removed for the next experiment after use, the test tube is briefly drained when lifted out of the water bath. Then, when the test tube is removed from the positioning chamber 4, the wiping end of the positioning rod 5 abuts against the tube wall to wipe the tube wall, reducing water droplets falling into the external environment. The positioning block 6 can have a large height, and the positioning through hole is long enough that multiple sets of positioning rods 5 can be arranged vertically. The test tube can repeatedly enter and exit the positioning through hole to set the position of the positioning rod 5, improving the wiping effect of the tube wall.

[0028] Based on the above embodiments, in some preferred embodiments, the test tube positioning unit further includes a positioning block 6, which has a predetermined working height and working width. The positioning block 6 is slidably disposed on the connecting rod 2, and a through hole is opened along the height direction to form the positioning chamber 4. An adaptive clamping unit is disposed in the positioning chamber 4 and performs corresponding clamping operations in the positioning chamber 4.

[0029] Specifically, the adaptive clamping unit includes a limiting rod 8, which moves radially through the corresponding position of the side wall of the positioning chamber 4; a clamping plate 9, which is assembled on one end of the limiting rod 8 located inside the positioning chamber 4, and whose clamping working surface has a predetermined curvature; and a support spring 10, which is wound around the limiting rod 8 and located between the clamping plate 9 and the inner wall of the positioning chamber 4. Insert the test tube into the top of the positioning chamber 4, pull the handle of the limiting rod 8, and the clamping plates 9 in the positioning chamber 4 move away from each other. The support spring 10 is compressed. After the test tube passes the clamping plate 9 to the appropriate position, slowly release the handle of the limiting rod 8. The clamping plate 11 is pushed against the corresponding position on the outer wall of the test tube by the reverse force of the support spring 10, thus clamping the test tube. Here, it is preferable to configure a friction layer on the clamping working surface of the clamping plate 9 to enhance the stability of clamping. It should be noted that when the test tube is inserted downward into the positioning chamber 4, the end of the positioning rod 5 is pressed down and against the test tube wall to assist in positioning the test tube.

[0030] The specific usage is as follows: This device is used in conjunction with a corresponding water bath, a connecting rod 2 of the corresponding length, and a corresponding number of positioning units. After installation by the installation unit, the test tube is inserted into the positioning chamber 4 from the top or bottom. The clamping plate 9 clamps the test tube appropriately, and the positioning rod 5 provides auxiliary positioning, increases friction, and improves clamping stability. During the water bath, the immersion height of the test tube in the water bath can be adjusted by the multi-stage telescopic rod. After the water bath is completed, the test tube can be lifted for drainage. When the test tube is pulled out, the wiping end of the positioning rod 5 can wipe the tube wall appropriately to reduce water on the outer wall of the test tube and reduce water droplets falling into the external environment. In addition, the positioning block 6 can be set to a longer height so that there is a certain height difference between the position of the clamping plate 9 and the position of the positioning rod 5. Multiple sets of positioning rods 5 arranged in a ring array can be set up to repeatedly pull up and insert the test tube to wipe the test tube wall.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In summary, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention. Each component of this application can be driven by a corresponding external motor; this is prior art and will not be elaborated upon here.
