Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermometer clamp technology, and in particular to a thermometer clamp and oven temperature calibration structure. Background Technology
[0002] Temperature control is crucial in industrial production, laboratory research, and daily life. Especially in heating equipment such as ovens, accurate temperature calibration directly affects product quality and experimental accuracy. Currently, oven temperature control primarily relies on the oven's built-in temperature controller, which may contain some error. For experiments requiring precise temperature readings, an additional thermometer is typically needed to accurately monitor the oven's internal temperature.
[0003] However, how to stably and accurately fix the thermometer in a specific position within the oven to obtain reliable temperature data has always been a problem that needs to be solved. Currently, the conventional method is to directly insert the thermometer into the cover 9 at the exhaust vent on top of the oven (e.g., Figure 4 As shown, the cover 9 has a disc-shaped cavity design inside, with an open bottom and a closed top. A base is designed around the bottom of the cover 9, and the base is fixed to the oven with screws. There is a round hole 91 in the center of the top surface of the cover 9, and six fan-shaped windows 92 are evenly opened around the round hole 91. The thermometer is inserted through the round hole 91. In order to fix it, a long-tail clip is usually clamped on the outside of the thermometer. The thermometer is easily damaged by accidental contact or clamping, and the thermometer is easy to slip out of the clip. Utility Model Content
[0004] In view of the problems existing in the prior art, the present invention aims to provide a thermometer clamp and oven temperature calibration structure to stably clamp the thermometer at the exhaust port of the oven.
[0005] To achieve the above objectives, this utility model proposes a thermometer clamp, including a base, a clamp body, and a tightening head. The base has a stepped hole extending vertically, with the upper part of the stepped hole having a larger diameter than the lower part. The lower end of the clamp body is fixed in the upper part of the stepped hole, and the clamp body has a clamping hole coaxially formed with the lower part of the stepped hole. The upper part of the clamp body is designed as a ring of jaws. The tightening head is threaded onto the outside of the ring of jaws. The lower part of the inner hole of the tightening head is a circular hole, and the upper part of the inner hole is a tapered hole with a diameter that gradually decreases from bottom to top. The inner hole, clamping hole, and stepped hole of the tightening head are all through holes through which a thermometer can pass. When the thermometer is inserted into the clamping hole, turning the tightening head will cause it to press the jaws inward, thereby clamping the thermometer tightly with the ring of jaws.
[0006] In the above solution: the lower end of the chuck body is fixed to the upper part of the stepped hole by threads, which facilitates disassembly and replacement.
[0007] In the above scheme, a rubber sleeve is pasted inside the entire gripper ring, which helps to increase the gripping force and anti-slip performance.
[0008] In the above solution: a step is provided at the lower middle part of the chuck body, and the step abuts against the top surface of the base, which can limit the screwing depth of the chuck body and improve the overall stability of the entire clamp.
[0009] In the above scheme: the lower end of the base extends outward with an outer ring of seats, so that the base is in the shape of an inverted "T". The stepped hole is located in the center of the base to facilitate the placement and fixation of the clamp.
[0010] This utility model also proposes a temperature calibration structure for an oven, including a thermometer and an oven. The top of the oven is provided with an exhaust port, and the oven also includes the aforementioned thermometer clamp. The thermometer is clamped on the thermometer clamp, and the thermometer clamp is placed at the exhaust port of the oven. The measuring end of the thermometer extends into the exhaust port.
[0011] In the above solution: a cover is provided at the exhaust port on the top of the oven. The cover has a disc-shaped cavity design, open at the bottom and closed at the top. A base is designed around the outer periphery of the bottom of the cover, and the base is fixed to the oven with screws. A circular hole is provided at the center of the top surface of the cover, and six fan-shaped windows are evenly distributed around the circular hole. The thermometer holder is placed in the inner area of the six fan-shaped windows, and the lower part of its stepped hole is aligned with the circular hole. The measuring end of the thermometer extends into the circular hole. This structure can ensure both accurate thermometer measurement and good exhaust of the oven.
[0012] The beneficial effects of this utility model are:
[0013] 1. The thermometer clamp, through its base, clamp body, and tightening head design, achieves a stable grip on the thermometer. The inner hole design of the tightening head makes operation simple; clamping or releasing the thermometer is achieved by simply turning it. The clamping stability is good, and the thermometer is not prone to slipping. 2. The clamping hole, the inner hole of the tightening head, and the stepped hole are all through-hole designs, accommodating thermometers of different diameters and improving the clamp's versatility. 3. The stepped hole design allows the clamp body to be firmly fixed to the base, and the clamping hole communicates with the lower part of the stepped hole, facilitating thermometer insertion and clamping. 4. In the oven temperature calibration structure, the thermometer clamp is placed at the oven's exhaust vent, with the thermometer's measuring end extending into the exhaust vent. This allows for real-time measurement of the oven's internal temperature. The thermometer clamp has good placement stability and is not easily affected by airflow within the oven, effectively ensuring the accuracy of the measurement results. 5. This thermometer clamp is not limited to temperature calibration in ovens; it can also be used in other applications where thermometers need to be clamped, such as laboratories and production lines.

[0018] Figure 4 This is a schematic diagram of the cover's structure. Detailed Implementation
[0019] like Figure 1 As shown in Figure 4, a thermometer clamp mainly consists of a base 1, a clamp body 2, and a tightening head 3. The lower end of the base 1 extends outward with an outer ring, making the base 1 in an inverted "T" shape. The base 1 has stepped holes 6 extending vertically, which are located at the center of the base, and the diameter of the upper part of the stepped hole 6 is larger than that of the lower part.
[0020] The lower end of the chuck body 2 is fixed in the upper part of the stepped hole 6, and a clamping hole 7 communicating with the lower part of the stepped hole 6 is coaxially provided on the chuck body 2. Specifically, the lower end of the chuck body 2 is fixed in the upper part of the stepped hole 6 by threads, which facilitates disassembly and replacement.
[0021] The upper part of the chuck body 2 is designed as a ring of jaws 8. The tightening head 3 is threaded onto the outside of the ring of jaws 8. The lower part of the inner hole of the tightening head 3 is a round hole, and the upper part of the inner hole is a tapered hole with a diameter that gradually decreases from bottom to top. The inner hole, the clamping hole 7, and the stepped hole 6 of the tightening head 3 are all through holes that allow the thermometer to pass through. When the thermometer 5 is inserted into the clamping hole 7, turning the tightening head 3 will cause it to press the jaws 8 inward, thereby clamping the thermometer 5 with the ring of jaws 8.
[0022] Specifically, a rubber sleeve 4 is pasted inside the entire gripper 8 to increase clamping force and anti-slip performance.
[0023] Specifically, a step 21 is provided at the lower middle part of the chuck body 2. The step 21 abuts against the top surface of the base 1, which can limit the screwing depth of the chuck body 2 and improve the overall stability of the entire chuck.
[0024] An oven temperature calibration structure mainly consists of a thermometer 5, an oven, and a thermometer clamp.
[0025] The oven has an exhaust port at the top. The thermometer 5 is clamped on a thermometer holder, which is placed at the exhaust port of the oven. The measuring end of the thermometer 5 extends into the exhaust port.
[0026] Specifically, a cover 9 is provided at the exhaust port on the top of the oven. The interior of the cover 9 is a disc-shaped cavity design, open at the bottom and closed at the top. A base is designed around the outer periphery of the bottom of the cover 9, and the base is fixed to the oven with screws. A circular hole 91 is provided at the center of the top surface of the cover 9, and six fan-shaped windows 92 are evenly distributed around the circular hole 91. The thermometer holder is placed in the inner area of the six fan-shaped windows 92, and the lower part of its stepped hole 6 is aligned with the circular hole 91. The measuring end of the thermometer 5 extends into the circular hole 91. This structure can ensure the accurate measurement of the thermometer 5 and the good exhaust of the oven.
[0027] Specifically, the thermometer clamp is usually 4-8cm high. The thermometer clamp is generally held in the area of the lower part of the thermometer 5 where no scale lines are drawn. The area of the thermometer 5 with scale lines is exposed outside the thermometer clamp and is not blocked or covered by the thermometer clamp, making it convenient for staff to read the temperature directly.
