[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 3, the utility model provides an embodiment: an auxiliary device for calibrating a small thermometer, including a thermometer calibrating machine 1, which is used to calibrate the small thermometer. It is a prior art, so it will not be described in detail in this case. The thermometer calibrating machine 1, the inner wall of the top of the thermometer calibrating machine 1 is provided with a placing disk 2, which provides a platform for placing the thermometer, and is used to insert the bottom end of the small thermometer into the constant temperature bath in the thermometer calibrating machine 1 through the placing disk 2. A placing hole 3 is opened through the top of the placing disk 2 to accommodate multiple small thermometers, providing a preliminary positioning space for the thermometer, and there are multiple groups of placing holes 3. The inner wall of the placing hole 3 is provided with an anti-slip strip 4, which increases the gap between the thermometer and the thermometer. The friction force helps to improve the stability of the thermometer. A clamping assembly is provided on the inner wall of the placement plate 2. The clamping assembly includes a limit plate 51. The outer wall of the limit plate 51 rotates on the inner wall of the placement plate 2 to provide a basis for installation and rotation of the components for clamping the thermometer. A limit hole 52 is provided at the top of the limit plate 51 near the bottom of the placement hole 3. The limit hole 52 is used to place the thermometer. By rotating the limit plate 51, the splint 53 is driven to cooperate with the anti-slip strip 4, so as to stably clamp the thermometer, effectively avoiding the risk of the thermometer falling into the constant temperature bath due to accidental slipping. The outer side of the anti-slip strip 4 is arranged on the inner wall of the limiting hole 52, which can limit the limit plate 51 and cooperate with the splint 53 to clamp the thermometer.

[0034] Reference Figure 2 - Figure 4 The top of the rotating rod 55 is fixedly connected to a twist cap 56, which is turned clockwise to drive the rotating rod 55 to rotate, thereby driving the limit plate 51 to rotate, and quickly clamping the thermometer.

[0035] Furthermore, there are two groups of limit plates 51, and both groups of limit plates 51 are arranged on the inner wall of the placement plate 2, clamping the thermometer from the upper and lower positions to enhance the stability and reliability of clamping. The length of the clamping plate 53 arranged on the inner wall of the lower group of limit plates 51 is slightly longer than the clamping plate 53 arranged in the upper group of limit plates 51, which can better adapt to thermometers of different lengths. At the same time, in order to provide different fulcrums and clamping force distributions during clamping to more effectively fix the thermometer and effectively avoid the risk of the thermometer falling into the constant temperature bath due to accidental slipping, the end of the clamping plate 53 close to the anti-slip strip 4 is set in an arc shape, which can better fit the thermometer, thereby increasing the contact area with the thermometer, thereby improving the stability and reliability of clamping. It is made of rubber material and can provide a certain buffer when clamping the thermometer to avoid damage to the thermometer. At the same time, the friction of rubber is large, which can enhance the firmness of clamping and prevent the thermometer from sliding or falling off during the clamping process.

[0036] Reference Figure 2 、 Figure 5 and Figure 6 A limit assembly is provided at the top of the placement disk 2. The limit assembly includes a fixed cylinder 61, which provides support and guidance for the rotation and sliding of the rotating rod 55. The fixed cylinder 61 is fixedly connected to the top of the placement disk 2. The outer wall of the rotating rod 55 rotates and is slidably connected to the inner wall of the fixed cylinder 61. A sliding tooth 62 is provided at the top of the fixed cylinder 61. The sliding tooth 62 is provided with multiple groups, and the top is inclined. When the limit tooth 65 rotates clockwise, it can drive the limit tooth 65 and the torsion cap 56 to move upward. At the same time, the sliding tooth 62 contacts the vertical surface of the limit tooth 65 to limit the torsion cap 56 and the rotating rod 55. The rotating rod 55 is fixedly connected to a baffle 63 near the inner side of the fixed cylinder 61 for supporting the reset spring 64.

[0037] Furthermore, the outer wall of the baffle 63 is slidably connected to the inner wall of the fixed cylinder 61, and the top of the baffle 63 is elastically connected to the fixed cylinder 61 by a return spring 64. The elastic force of the return spring 64 drives the rotating rod 55 and the twist cap 56 to reset, thereby improving the stability of the rotating rod 55 and the twist cap 56. A limiting tooth 65 is provided at the bottom end of the twist cap 56 near the top of the sliding tooth 62, and the bottom end of the limiting tooth 65 slides on the top of the sliding tooth 62. The cooperation between the limiting tooth 65 and the sliding tooth 62 plays a role in locking and limiting the rotation of the rotating rod 55. When the inclined surface of the bottom end of the limiting tooth 65 slides on the inclined surface of the top end of the sliding tooth 62, the position of the rotating rod 55 can be fixed by the engagement of the two, thereby keeping the clamping state of the splint 53 on the thermometer stable, thereby ensuring that the precise position of the thermometer is fixed during the calibration process, and the bottom end of the twist cap 56 slides on the top of the fixed cylinder 61.

[0038] Working principle: When in use, first insert the small thermometer into the placement hole 3 opened at the top of the placement plate 2, and then rotate the twist cap 56 clockwise. The twist cap 56 rotates, driving the inclined surface of the bottom end of the limiting tooth 65 at its bottom end to slide along the inclined surface of the top end of the sliding tooth 62, which will drive the limiting tooth 65 and the twist cap 56 to move upward, thereby driving the baffle 63 to move and squeeze the reset spring 64.

[0039] At the same time, the twist cap 56 drives the rotating rod 55 to rotate, and the protrusion on the rotating rod 55 enables the rotating rod 55 to drive the limiting plate 51 to rotate. As the limiting plate 51 rotates, the clamping plate 53 in the limiting hole 52 moves toward the thermometer under the elastic action of the compression spring 54, thereby clamping the thermometer.

[0040] At this time, the rotation of the torsion cap 56 is stopped. Under the elastic force of the reset spring 64, the vertical surface of the sliding tooth 62 is driven to contact the vertical surface of the limiting tooth 65, thereby limiting the torsion cap 56 and the rotating rod 55, thereby fixing the position of the rotating rod 55 and keeping the clamping state of the splint 53 on the thermometer stable.

[0041] Since two sets of limit plates 51 are provided, and the length of the clamping plate 53 in the lower limit plate 51 is slightly longer than that in the upper one, the thermometer can be clamped more stably and reliably from the upper and lower positions, adapting to thermometers of different lengths, and providing different fulcrum points and clamping force distributions, effectively preventing the thermometer from accidentally slipping and falling into the constant temperature bath.

[0042] When the thermometer needs to be released, the operator holds the thermometer with one hand and pulls the twist cap 56 upward with the other hand and rotates the twist cap 56 in the opposite direction. The rotating rod 55 drives the limit plate 51 to reset, thereby releasing the splint 53 from the thermometer and the thermometer can be taken out.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
