Description

Technical Field

[0001] This utility model belongs to the technical field of constant temperature metal bath equipment, specifically relating to a constant temperature metal bath equipment with uniform heating. Background Technology

[0002] Thermostatic metal baths are commonly used temperature control devices in laboratories, typically used to achieve accurate temperature control of samples, reactants, or instrument components. Their applications are very wide-ranging. Whether in chemical experiments, biological experiments, or materials research, thermostatic metal baths provide a reliable temperature control environment. In organic synthesis reactions, thermostatic metal baths can ensure a stable temperature of the reaction system. For example, the existing patent with publication number CN217368463U describes "an improved thermostatic metal bath with uniform heat conduction, relating to the field of biochemical instrument technology, including a box body, a control panel on the front of the box body, protective railings on both sides of the box body, support legs at the four corners of the bottom of the box body, the box body including an outer shell, support legs fixedly installed at the four corners of the bottom of the outer shell, and a heat-conducting block disposed on the top of the outer shell within the cavity of the heat-insulating cover." It can be seen that the application describes a common thermostatic metal bath device with uniform heating, which can ensure uniform heating of subsequent test tube samples through evenly spaced holes on the heat-conducting block.

[0003] In existing technologies, the constant-temperature metal bath equipment with uniform heating lacks a corresponding limiting structure on the heat-conducting test tube holder during actual use. This can cause the test tube to tilt or wobble after being inserted into the socket, potentially affecting the subsequent heating stability and uniformity. Furthermore, the unused test tube sockets on the heat-conducting test tube holder are not effectively shielded, making it easy for foreign objects to fall in and affect cleanliness. Therefore, this utility model proposes a constant-temperature metal bath equipment with uniform heating. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example

[0026] See also Figures 1 to 6 This is an embodiment of the present invention, which provides a technical solution: a constant-temperature metal bath device with uniform heating, comprising...

[0027] The machine body 1, the top seat 2 set on the top of the machine body 1, and the heat-conducting test tube seat 3 set on the top of the top seat 2, with the bottom end of the heat-conducting test tube seat 3 inserted into the inside of the top seat 2. The top of the heat-conducting test tube seat 3 is provided with multiple test tube insertion holes 31. The above structural principles are all technologies that have been disclosed in the prior art. For details, please refer to the existing patent with publication number CN217368463U. It will not be elaborated here.

[0028] And two limiting structures 5 are provided on the inner wall of the test tube insertion hole 31, including a telescopic groove 51 opened on the inner wall of the test tube insertion hole 31, a telescopic block 52 installed in the telescopic groove 51, and a spring B53. The telescopic block 52 is movably installed in the telescopic groove 51 through the spring B53, and the end of the telescopic block 52 extends to the inner side of the test tube insertion hole 31. When the test tube is inserted into the test tube insertion hole 31, the bottom end of the test tube will first squeeze the end of the telescopic block 52, so that the telescopic block 52 is squeezed into the telescopic groove 51, and the spring B53 is gradually compressed. When the bottom end of the test tube is successfully inserted, the symmetrical clamping and pressing of the two telescopic blocks 52 can clamp the inserted test tube, ensuring the heat stability and uniformity of the test tube in the subsequent experiment, and preventing the test tube from tilting.

[0029] And a sealing cover plate 4 is slidably set on the top of the heat-conducting test tube holder 3, and the sealing cover plate 4 covers and blocks one row of test tube insertion holes 31, which can block a row of unused test tube insertion holes 31 to prevent foreign objects from entering these unused test tube insertion holes 31, thus playing a protective and blocking role.

[0030] The sealing cover plate 4 extends to both sides of the heat-conducting test tube base 3, and side slide seats 41 are slidably provided on both sides of the heat-conducting test tube base 3. A side connecting plate 42 is movably installed on the side of the side slide seat 41. The top of the side connecting plate 42 is fixed to the bottom surface of the sealing cover plate 4, so that the sealing cover plate 4 can slide smoothly on the top of the heat-conducting test tube base 3. A movable groove 45 is opened on the side of the side slide seat 41. A movable block 47 is slidably provided in the movable groove 45, and one end of the movable block 47 extends to the side of the side slide seat 41 and is fixed to the side connecting plate 42. A spring A46 is also provided on the inner side of the movable groove 45 relative to the top of the movable block 47. Under the pushing of the spring A46, the movable block 47 will carry the side connecting plate. 42 and the sealing cover 4 move down to ensure that the sealing cover 4 can be stably pressed on the top of the heat-conducting test tube base 3 during daily use, blocking the unused test tube insertion hole 31. The bottom center of the sealing cover 4 is fixed with a positioning block 44 corresponding to the test tube insertion hole 31, and the positioning block 44 is embedded in the test tube insertion hole 31, so that the sealing cover 4 can be limited when pressed on the top of the heat-conducting test tube base 3, and it is not easy to slip. Only when the operator lifts the sealing cover 4 with force, the side connecting plate 42 moves up with the movable block 47, and the spring A46 is gradually compressed, so that the positioning block 44 can be moved out of the test tube insertion hole 31. Only then can the sealing cover 4 be slid to change the position of the sealing cover 4.

[0031] The bottom end of spring A46 is fixed to the top surface of movable block 47, and the top end of spring A46 is fixed to the inner wall of the bottom end of movable groove 45 to ensure the stable installation of spring A46.

[0032] The heat-conducting test tube base 3 has side slides 32 on both sides of its surface. A side slider 43 is welded and fixed to the side of the side slide seat 41. The side slider 43 slides in the side slides 32, so that the side slide seat 41 can slide smoothly on the side of the heat-conducting test tube base 3.

[0033] The telescopic block 52 has a cylindrical groove inside. One end of the spring B53 is inserted into and fixed in the cylindrical groove, and the other end of the spring B53 is fixed on the inner wall of the telescopic groove 51. This can limit the spring B53 and prevent it from shifting. At the same time, since the spring B53 is welded and fixed to the telescopic block 52, the telescopic block 52 can be stably installed in the telescopic groove 51, preventing the telescopic block 52 from falling off, and does not affect the sliding of the telescopic block 52 when it is squeezed later.

[0034] The front surface of the body 1 is provided with an operation screen 11.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
