Description

Technical Field

[0001] The utility model relates to the technical field of spectrophotometers, in particular to an ultra-micro spectrophotometer. Background Art

[0002] When using cuvette detection, if the detection kinetic experiment requires a long time of detection, during the detection process, long-term static state will cause many samples to easily precipitate and form films, thus affecting the test results. Mixing is required before measurement. Therefore, a stirrer is required for spectrophotometer cuvette detection. Generally, the instrument has a built-in magnetic stirrer and is equipped with a magnetic stirrer to mix the samples. The magnetic material repels each other and the polarity of the two ends of the base is continuously changed to drive the magnetic stirrer to rotate. The rotation of the magnetic stirrer drives the sample to rotate, so that the sample is evenly mixed. However, the magnetic stirrer needs to be placed separately when not in use and is easy to lose.

[0025] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] See also Figures 1 to 3 The utility model provides an ultra-micro spectrophotometer, comprising a workbench 1 and a stirring structure 2 detachably arranged on the workbench 1, wherein the stirring structure 2 comprises a driving part 201 and a stirring part 202 connected to each other, and the workbench 1 is provided with a storage structure for storing the stirring structure 2;

[0027] The storage structure comprises:

[0028] A storage tank 3, provided on the workbench 1, for accommodating the driving unit 201;

[0029] A storage tube 4, connected to the storage tank 3, and used to accommodate the stirring part 202;

[0030] A plurality of limit blocks 5 are arranged at intervals in the storage slot 3, and each of the limit blocks 5 includes a first limit portion 501 and a second limit portion 502 which are rotatably connected. The first limit portion 501 is fixed to the inner wall of the storage slot 3, and the first limit portion 501 and the second limit portion 502 are connected via a torsion spring 7. When an external force drives the second limit portion 502 to rotate forward, the second limit portion 502 rotates in a direction away from the first limit portion 501 and gradually extends into the storage slot 3 to support the driving portion 201. After the external force disappears, the second limit portion 502 rotates in the direction of the first limit portion 501 to fold the first limit portion 501 and the second limit portion 502.

[0031] In this embodiment, in order to facilitate the storage and removal of the stirring structure 2, a storage tank 3 is provided on the workbench 1, and the storage tank 3 is connected to the storage tube 4. When the stirring structure 2 is not in use, the driving part 201 and the stirring part 202 are respectively stored in the storage tank 3 and the storage tube 4, which saves space and protects the stirring structure 2; a plurality of limit blocks 5 in a circumferential array are provided in the storage tank 3, each limit block 5 is composed of a first limit part 501 and a second limit part 502 connected in rotation, the first limit part 501 is fixed on the inner wall of the storage tank 3, and the second limit part 502 is rotatably connected to the first limit part 501 through the rotating shaft 6, so that the second limit part 502 rotates relative to the first limit part 501 when subjected to external force. When it is necessary to put the stirring structure 2 into the storage tank 3, the second limit part 502 is rotated forward, and the second limit part 502 will rotate in a direction away from the first limit part 501 and extend into the storage tank 3. The extension of the second limiting portion 502 plays a role in supporting the driving portion 201, so that it can be suspended and stably arranged in the storage slot 3. On the other hand, the first limiting portion 501 and the second limiting portion 502 are connected by the torsion spring 7. When the external force is removed (it can be understood that the elastic force of the torsion spring 7 should be less than the gravity of the driving portion 201), that is, when the driving portion 201 is separated from the second limiting portion 502, the restoring force of the torsion spring 7 will drive the second limiting portion 502 to rotate toward the first limiting portion 501, and fold the two together, thereby reducing the occupied space and facilitating the cleaning of the storage slot 3 without dead ends. At the same time, it is also convenient for the stirring structure 2 to be easily taken out of the storage slot 3. The driving portion 201 is suspended on the storage slot 3 through the second limiting portion 502, so as to increase the contact area with the driving portion 201 and improve the stability of the stirring structure 2 when placed. The upper part of the driving portion 201 can protrude outside the storage slot 3 when stored, so as to facilitate the stirring structure 2 to be taken and placed at will.

[0032] A rotating shaft 6 is provided at the connection between the first limiting portion 501 and the second limiting portion 502 , and the torsion spring 7 is sleeved on the outer side of the rotating shaft 6 .

[0033] In this embodiment, the first limiting portion 501 and the second limiting portion 502 are connected by a rotating shaft 6, and the rotating shaft 6 serves as the rotation center between the two, so that the second limiting portion 502 can rotate freely relative to the first limiting portion 501. The torsion spring 7 is mounted on the outer side of the rotating shaft 6 to help the second limiting portion 502 to rotate smoothly under the action of external force and automatically reset after the external force disappears.

[0034] The second limiting portion 502 is provided with an empty slot 503 for avoiding the rotating shaft 6 and the first limiting portion 501 .

[0035] In this embodiment, the empty groove 503 allows the second limiting portion 502 to rotate more smoothly and unimpeded. Even at the maximum rotation angle, the continuity of rotation will not be affected or damaged due to structural collision, ensuring that no additional space is occupied during the folding or unfolding of the second limiting portion 502. When the second limiting portion 502 returns to its original position, the empty groove 503 wraps the first limiting portion 501 therein, saving space.

[0036] The first limiting portion 501 is vertically arranged. Under the action of external force, the first limiting portion 501 and the second limiting portion 502 are perpendicular to each other.

[0037] In this embodiment, when an external force acts on the second limiting portion 502 to rotate it, the first limiting portion 501 and the second limiting portion 502 will eventually form a mutually perpendicular state, which helps to maintain the stability and compactness of the overall structure while supporting the driving portion 201. The vertical setting can utilize space more efficiently, especially in an environment with limited height. The conversion from unfolded support to folded storage can be achieved through rotational movement without increasing the occupied space in the horizontal direction.

[0038] The storage slot 3 is stacked with a plurality of gaskets 8 , and the gaskets 8 are located below the second limiting portion 502 .

[0039] In this embodiment, the gasket 8 is arranged below the second limiting portion 502 to ensure the rotation angle of the second limiting portion 502. Under the limitation of the gasket 8, it can form a mutually perpendicular state with the first limiting portion 501, which is convenient for stably supporting the driving portion 201.

[0040] A rubber sheet 9 is disposed on the top of the storage tube 4 . The rubber sheet 9 is provided with a receiving opening 901 for avoiding the driving part 201 .

[0041] In this embodiment, the rubber material has good elasticity and sealing properties. After the stirring part 202 passes through the receiving port 901 and enters the storage tube 4, the rubber sheet 9 can return to its original shape and fit tightly on the top of the storage tube 4 to form a sealing layer. This can not only prevent dust, liquid or other contaminants from entering the storage tube 4 and protect the stirring part 202 from the influence of the external environment, but also the stirring part 202 entering the storage tube 4 through the receiving port 901 can avoid direct contact between the stirring part 202 and the storage tube 4, thereby avoiding damage to the stirring part 202.

[0042] The receiving opening 901 is provided with a cleaning sponge.

[0043] In this embodiment, the cleaning sponge is located at the receiving port 901. When the stirring portion 202 of the stirring structure 2 enters and exits the storage tube 4, the dust, residual liquid or other impurities on its surface can be wiped off, which is very important for maintaining the cleanliness of the inside of the instrument and preventing contamination, especially in ultra-micro spectrophotometers that perform high-precision measurements. Any tiny contamination may affect the accuracy of the measurement results.

[0044] An opening 401 is formed at the bottom of the storage tube 4 , and a cover 10 is detachably provided on the opening 401 for closing or opening the opening 401 .

[0045] In this embodiment, an opening 401 is provided at the bottom of the storage tube 4, and a sealing cover 10 is screwed onto the opening 401. When the cleaned stirring part 202 is placed in the storage tube 4, the water remaining thereon will not drip directly into the storage tube 4, but will drip onto the sealing cover 10. The separation of the sealing cover 10 facilitates the treatment of the residual water.

[0046] The second limiting portion 502 is provided with a plurality of friction portions.

[0047] In this embodiment, when the second limiting portion 502 rotates or supports the stirring structure 2, the friction portion (not shown) can provide additional resistance to prevent the driving portion 201 from sliding freely on the second limiting portion 502 due to external force.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
