Description

Technical Field

[0001] This utility model relates to the field of test tube rack technology, specifically a portable constant temperature test tube rack. Background Technology

[0002] Test tube racks are used to store test tubes, and sometimes test tubes can be placed on the rack to observe the phenomena of a certain experiment. They can also be used to dry test tubes. Test tube racks are the most basic experimental instruments in a chemistry laboratory. The test tube racks are equipped with a corresponding number of small wooden posts and holes. These holes allow the test tubes to be placed upright for later use or to continue to observe the reaction.

[0003] However, existing test tube racks are generally one-piece structures that cannot be disassembled, resulting in a large space occupied by the racks and making them difficult to carry and transport. At the same time, the temperature of the liquid inside the test tubes is easily lowered, and existing test tube racks are not good at keeping the test tubes warm, thus failing to meet current needs. To address this, we propose a portable constant temperature test tube rack. Utility Model Content

[0004] The purpose of this utility model is to provide a portable constant temperature test tube rack to solve the problem mentioned in the background art that the test tube rack is generally an integral structure that cannot be disassembled, resulting in the test tube rack occupying a large space and making it difficult to carry and transport.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable constant temperature test tube rack, comprising two fixing plates, each fixing plate having a square groove at one of its four corners, a support component being engaged between two opposite square grooves, and a locking component being movably provided at the upper and lower ends of the support component, the locking component being engaged within the square groove, and multiple mounting holes being provided through the end face of the fixing plate, a first sleeve being engaged between two opposite mounting holes, a second sleeve being adhered to the inside of the first sleeve, and a test tube being inserted into the inside of the second sleeve.

[0006] Preferably, the fixing plate has an outer annular groove around its upper and lower ends, and the outer annular groove is engaged with the mounting hole.

[0007] Preferably, the top of the second sleeve is provided with an inner annular groove, which is engaged with the upper end of the test tube.

[0008] Preferably, both the first sleeve and the second sleeve are made of thermal insulation rubber material.

[0009] Preferably, the support component includes a support column inserted between two fixed plates, the support column having an inner movable cavity inside, and two connecting columns fixedly connected to the upper and lower ends of the inner movable cavity.

[0010] Preferably, the snap-fit ​​component includes a snap-fit ​​plate that moves laterally inside the inner movable cavity. A push-pull block is fixedly connected to the upper end of the snap-fit ​​plate. Movable holes are provided through both sides of the surface of the snap-fit ​​plate, and the movable holes and the connecting post are laterally movable.

[0011] Preferably, one side of the snap-fit ​​plate is provided with a connecting groove, and a spring is fixedly connected between the two connecting grooves.

[0012] Preferably, the cross-section of the snap-fit ​​plate is designed as an L-shaped structure, and the upper end of the snap-fit ​​plate is inserted into a square groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The separation operation between the snap-fit ​​component and the fixing plate in this utility model realizes the separation of the fixing plate and the supporting component, thereby allowing the two fixing plates and four supporting components to be disassembled. Compared with the overall test tube rack, the disassembled fixing plates and supporting components occupy less space, making them easy to transport and carry, thus realizing its portable function.

[0015] 2. This utility model uses a push-pull block to move laterally towards the inside of the test tube, causing the push-pull block to move the snap-fit ​​plate laterally. The relative movement of the two snap-fit ​​plates compresses the spring between them, thereby separating the upper end of the snap-fit ​​plate from the upper end of the fixing plate. The test tube can then be inserted into the second sleeve. The first and second sleeves are made of heat-insulating rubber material, thus allowing the entire first and second sleeves to keep the liquid inside the test tube warm. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1 to 5 An embodiment of this utility model provides a portable constant temperature test tube rack, including two fixing plates 1. Each of the four corners of the fixing plate 1 is provided with a square groove 10. A support component 2 is snapped between two opposite square grooves 10. The upper and lower ends of the support component 2 are provided with snap-fit ​​components 3, which are snapped into the square grooves 10. Multiple mounting holes 4 are provided through the end face of the fixing plate 1. A first sleeve 5 is snapped between two opposite mounting holes 4. A second sleeve 7 is adhered inside the first sleeve 5. A test tube 6 is inserted inside the second sleeve 7.

[0024] The aforementioned fixing plate 1 has an outer annular groove 8 around its upper and lower ends, which is snapped into the mounting hole 4. The second sleeve 7 has an inner annular groove 9 at its top end, which is snapped into the upper end of the test tube 6. Both the first sleeve 5 and the second sleeve 7 are made of soft thermal insulation rubber material. When the mounting hole 4 on the overall fixing plate 1 is fixedly connected to the first sleeve 5, the mounting hole 4 on the fixing plate 1 is snapped into the outer annular groove 8 around the end face of the first sleeve 5, so that the overall first sleeve 5 can be snapped into the fixing plate 1, preventing the overall first sleeve 5 from shaking between the two fixing plates 1, and further improving the fixation of the overall test tube 6.

[0025] The test tube 6 can be inserted into the second sleeve 7. The upper end of the second sleeve 7 is provided with an inner annular groove 9. The inner annular groove 9 is pressed against the upper end of the test tube 6. This setting allows the inner annular groove 9 to limit the test tube 6, thus making it difficult for the test tube 6 to fall out of the second sleeve 7. The second sleeve 7 and the first sleeve 5 are bonded together as a whole. The first sleeve 5 and the second sleeve 7 are made of heat-insulating rubber material, thus allowing the first sleeve 5 and the second sleeve 7 to keep the liquid inside the test tube 6 warm.

[0026] In one optional embodiment, the constant temperature in this application can be achieved by using the insulation properties of the first sleeve 5 and the second sleeve 7 to keep the liquid inside the test tube 6 within a certain temperature range for a certain period of time. In this embodiment, temperature changes in the liquid inside the test tube 6 are not excluded. Furthermore, to achieve a more stable liquid temperature inside the test tube 6, in some optional embodiments, a heating electrode, a temperature measuring electrode, and a heating controller can be installed between the first sleeve 5 and the second sleeve 6, or on the inner wall of the second sleeve 7. The heating electrode can be a flexible electric heating element based on carbon materials, such as graphene heating electrodes, carbon fiber heating electrodes, or other existing flexible electric heating elements. The temperature measuring electrode can be positioned on the side of the heating electrode facing the test tube 6 to monitor the temperature of the heating electrode or the test tube wall temperature in real time and transmit the data to the heating controller, which controls the temperature of the heating electrode to maintain the liquid inside the test tube 6 within a certain temperature range.

[0027] The support component 2 includes a support column 201 inserted between two fixed plates 1. The support column 201 has an inner movable cavity 202 inside, and two connecting columns 203 are fixedly connected to the upper and lower ends of the inner movable cavity 202.

[0028] The snap-fit ​​component 3 includes a snap-fit ​​plate 301 that moves laterally inside the inner movable cavity 202. A push-pull block 302 is fixedly connected to the upper end of the snap-fit ​​plate 301. Movable holes 303 are provided through both sides of the surface of the snap-fit ​​plate 301. The movable holes 303 and the connecting post 203 are laterally movable and engaged. A connecting groove 304 is provided on one side of the snap-fit ​​plate 301. A spring 305 is fixedly connected between the two connecting grooves 304. The cross-section of the snap-fit ​​plate 301 is designed as an L-shaped structure. The upper end of the snap-fit ​​plate 301 is inserted into the square groove 10.

[0029] In use, the stretching force of the spring 305 can move the snap-fit ​​plates 301 on both sides laterally, so that the upper end of the snap-fit ​​plate 301 can be inserted into the upper end of the square groove 10. This arrangement allows the support column 201 and the fixing plate 1 to be snap-fit ​​connected. The four support components 2 are supported at each end corner between the two fixing plates 1 in this way, so that the fixing plate 1 and the support components 2 are assembled into a test tube rack, and thus the first sleeve 5 of the whole can be connected between the two mounting holes 4.

[0030] If the entire support component 2 is to be disassembled, the push-pull block 302 needs to be pushed laterally into the square groove 10, so that the push-pull block 302 drives the snap-fit ​​plate 301 to move laterally. By moving the two snap-fit ​​plates 301 relative to each other, the spring 305 between them is squeezed, thereby separating the upper end of the snap-fit ​​plate 301 from the upper end of the fixing plate 1. Then, the fixing plate 1 is lifted vertically, so that the square groove 10 in the middle of the fixing plate 1 and the snap-fit ​​plate 301 are separated.

[0031] The operation between the snap-fit ​​component 3 and the fixing plate 1 separates the fixing plate 1 and the supporting component 2, thereby disassembling the two fixing plates 1 and the four supporting components 2. The overall test tube rack occupies a large space, making it difficult to move and carry. In contrast, the disassembled fixing plates 1 and supporting components 2 occupy less space than the overall test tube rack, making them easier to move and carry, thus achieving its portable function.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
