[0028] Reference Figures 1 to 4This application provides a water bath nitrogen blowing apparatus, comprising: a chassis 100, wherein a water bath 110 is provided; a support mechanism 200, including a support plate 210 and a support rod 220, wherein the support plate 210 is placed in the water bath 110 and the support rod 220 is disposed on the support plate 210; and a sample holder disposed on the support rod 220, the sample holder including a base plate 310, a connecting plate 320 and a fixing plate 330, wherein the connecting plate 320 is disposed above the base plate 310 and connected to the base plate 310 via a first connecting rod 340, and the fixing plate 330 is disposed above the connecting plate 320 and connected to the connecting plate 320 via a second connecting rod 350, wherein the fixing plate 330 has a plurality of first through holes 331 on its circumference, and the second connecting rod 350 is located in the first through holes 331. Between 1, the connecting plate 320 is provided with a second through hole 321 corresponding to the first through hole 331. The connecting plate 320 is slidably provided with an adjusting plate 322 on the side of the second through hole 321 near the support rod 220. The adjusting plate 322 can move closer to or away from the second through hole 321. An elastic fixing ring 323 is provided on the side of the second through hole 321 away from the adjusting plate 322. The elastic fixing ring 323 is wrapped around the periphery of the second connecting rod 350. The bottom plate 310 is provided with an elastic locking position 311 corresponding to the first through hole 331. The nitrogen blowing mechanism 400 is provided on the support rod 220 and above the sample holder. The nitrogen blowing mechanism 400 is provided with a gas needle 410 that is raised and lowered. The gas needle 410 corresponds to the first through hole 331 and is used to blow out nitrogen gas.

[0029] During testing, a sample tube containing grease is placed on the sample tube holder 300. The adjusting plate 322 slides to abut one side of the sample tube, while the other side is secured by a spring-loaded retaining ring. The bottom of the sample tube is also secured by an elastic clip, ensuring the sample tube remains vertical. Then, the air needle 410 descends and inserts into the sample tube, blowing nitrogen gas into the grease. The sliding adjusting plate 322, in conjunction with the elastic retaining ring 323, secures the sample tube, and the bottom is secured by the elastic clip. This design accommodates sample tubes of different sizes, prevents tilting, maintains verticality, and improves sample tube stability. This facilitates the descent of the air needle 410 into the sample tube, resulting in a simple structure, easy operation, and improved work efficiency.

[0030] Reference Figures 1 to 4Furthermore, the connecting plate 320 is provided with a fixed seat 324, and the adjusting plate 322 is provided on the guide rod 325. The guide rod 325 passes through the fixed seat 324, and a spring member 326 is sleeved on the guide rod 325. The two ends of the spring member 326 abut against the fixed seat 324 and the adjusting plate 322, respectively. When the sample tube is placed on the sample tube support 300, the adjusting plate 322 slides towards the support rod 220 as the sample tube is inserted, and the adjusting plate 322 is tightly abutted against the sample tube under the action of the spring. Thus, the adjusting plate 322 cooperates with the elastic fixing ring 323 to self-adaptively fix the sample tube. The structure is simple and the operation is convenient.

[0031] The adjusting plate 322 has an arc surface on the side away from the guide rod 325, which increases the contact area between the adjusting plate 322 and the sample tube, thus improving the stability of the sample tube. Alternatively, the adjusting plate 322 can also have a V-groove on the side away from the guide rod 325, which not only improves the stability of the sample tube but also accommodates sample tubes of different specifications. This application does not limit the shape of the adjusting plate 322.

[0032] It should be noted that the sliding of the adjusting plate 322 can also be manually adjusted by a screw or automatically adjusted by a cylinder or other structure, and this application does not limit this.

[0033] In this embodiment, the elastic retaining ring 323 is configured as a spring ring. Of course, the elastic retaining ring 323 can also be configured as a rubber band, etc. Those skilled in the art can make reasonable choices regarding the structure of the elastic retaining ring 323 based on the actual situation, and this application does not impose any limitations on this.

[0034] It is conceivable that both the first through hole 331 and the second through hole 321 are provided with openings to facilitate the placement and removal of the sample tube, thereby improving work efficiency.

[0035] Reference Figures 1 to 3 In some embodiments of this application, the nitrogen blowing mechanism 400 further includes a mounting frame 420, with the gas needle 410 elliptically mounted on the mounting frame 420. The mounting frame 420 is provided with a gas chamber 430, which is connected to an inlet pipe 440 connected to a gas supply system. The gas chamber 430 is provided with an outlet pipe 450 connected to the gas needle 410. The inlet pipe 440 is equipped with a regulating valve, and the outlet pipe 450 is equipped with an outlet valve. The regulating valve allows for adjustment of the nitrogen delivery speed to adapt to different production requirements, simplifying operation. The outlet valve in the outlet pipe 450 allows for control of the gas flow of the corresponding gas needle 410, preventing resource waste.

[0036] As is easily understood, the water bath 110 is equipped with a heating plate to heat the water within it. The water bath 110 also includes a temperature sensor connected to the heating plate to detect the water temperature. By detecting the water temperature, the heating plate can adjust its heating accordingly, keeping the water in the water bath 110 within a set range and thus improving detection accuracy. Furthermore, the chassis 100 is equipped with a high-temperature alarm light connected to the temperature sensor. This structure enables the alarm light to illuminate at high temperatures, alerting operators and simplifying operation.

[0037] Furthermore, the side wall of the chassis 100 is provided with an operation panel 120, which is connected to the heating plate, temperature sensor and nitrogen blowing mechanism 400 respectively, so that the operation panel 120 can drive the start of the equipment and set the water temperature, making the operation more convenient.

[0038] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
