Description

Technical Field

[0001] This utility model relates to the field of temperature monitoring instrument technology, specifically a temperature measuring wire fixing device for a portable temperature monitoring instrument. Background Technology

[0002] During temperature calibration, temperature deviation, temperature fluctuation, and temperature uniformity are the most frequently monitored temperature parameters. Temperature deviation and temperature fluctuation are usually measured in the geometric center region of the temperature field, but temperature uniformity needs to be measured at different locations within the temperature field. The accuracy of the calibration location directly affects the evaluation of instrument performance. The measuring wires of digital thermometers or temperature monitoring instruments are mostly flexible and difficult to fix in a specific position. Manual fixing cannot guarantee that the measuring wire will be fixed in the same position every time or for every device during calibration; even slight movement will inevitably have a significant impact on the measurement results.

The main fixing post 1 is fixedly connected to the base 3. Multiple support rods 2 are provided and set on the circumferential surface of the main fixing post 1. A limiting assembly for gathering the temperature measuring wire is provided on the main fixing post 1.

[0024] The first end of the support rod 2 is fixedly connected to the threaded post 21, and the tail end of the support rod 2 is provided with a threaded hole that matches the threaded post 21.

[0025] Multiple threaded tubes 11 that match the threaded column 21 are fixedly connected to the circumferential surface of the main fixing column 1. Multiple threaded tubes 11 are provided and fixedly connected to the circumferential surface of the main fixing column 1 at equal intervals.

[0026] To fix the temperature measuring wire at different positions on the support rod 2, multiple sets of locking hook assemblies are provided on each support rod 2, and the locking hook assemblies are arranged at equal intervals on the support rod 2. The locking hook assembly includes a locking hook 31 with its upper end passing through the support rod 2, a limiting cylinder 32 sleeved on the upper end of the locking hook 31, and a return spring 33 with its upper end fixedly connected to the top of the locking hook 31. The lower end of the return spring 33 is fixedly connected to the limiting cylinder 32, which is fixedly connected to the support rod 2. The upper end of the locking hook 31 is straight, and the lower end of the locking hook 31 is a curved hook structure.

[0027] The limiting assembly includes arc-shaped rods 41 symmetrically arranged on the left and right sides of the main fixed post 1, and a locking plate 42 fixedly connected to the head end of the arc-shaped rods 41. The tail end of the arc-shaped rods 41 is hinged to the main fixed post 1, and a locking hole is provided on the locking plate 42. In order to further fix the temperature measuring wire of the temperature monitoring instrument to the main fixed post 1, a high-temperature resistant rubber pad is fixedly connected to the inner side wall of the arc-shaped rods 41. The rubber pad can increase the contact area between the arc-shaped rods 41 and the temperature measuring wire of the temperature monitoring instrument. After the operator attaches the temperature measuring wire of the temperature monitoring instrument to the main fixed post 1, the operator rotates the arc-shaped rods 41 on the left and right sides of the main fixed post 1 to align the locking holes on the locking plate 42. The operator then inserts a bolt into the locking hole and finally uses a nut to tighten the bolt.

[0030] Working principle: At the temperature measurement location, the operator first screws the main fixing column 1 onto the base 3. Then, according to the height of the temperature measurement location, selects an appropriate number of main fixing columns 1 and assembles them. Next, the operator selects an appropriate number of support rods 2 and assembles them. Then, according to the temperature measurement location, the operator installs the support rods 2 onto the appropriate threaded tubes 11. The operator then fixes the temperature measuring wire of the temperature monitoring instrument onto the support rod 2. The operator first pulls down the locking hook 31 to install the temperature measuring wire of the temperature monitoring instrument into the locking hook 31. After releasing the locking hook 31, under the action of the return spring 33, the locking hook 31 returns to its original position, thus fixing the temperature measuring wire of the temperature monitoring instrument. Then, after the operator attaches the temperature measuring wire of the temperature monitoring instrument to the main fixing column 1, the operator rotates the arc-shaped rods 41 on both sides of the main fixing column 1 to align the locking holes on the locking plate 42. The operator then inserts bolts into the locking holes and finally uses nuts to tighten the bolts. The operation is then complete.
