[0036] The base 1 is used for magnetic attraction to the inner wall of the sleeve 6, and the base 1 is provided with an adjusting screw hole 11 arranged vertically;

[0037] The base 1 can be magnetically attracted to the inner wall of the sleeve 6, so that the axial position of the base 1 in the sleeve 6 can be changed; as Figure 3As shown, by changing the left and right positions of the base 1 magnetically attracted to the inner wall of the sleeve 6, the left and right positions of the mounting plate 3 can be changed, and the left and right positions of the temperature recorder 4 on the mounting plate 3 can be changed.

Furthermore, the lower end of the boss structure is a strong magnetic structure, which saves costs while ensuring magnetic attraction strength, while the upper end does not use a strong magnetic structure to avoid affecting the adjustment of the adjusting stud 2.

[0046] In this embodiment, the adjustable bracket for the recorder is used by first calculating the length that the adjusting stud 2 needs to be adjusted based on the size of the sleeve 6 and the size of the bridge plug 5. Then, the adjusting stud 2 is initially adjusted, and the orientation of the mounting plate 3 is adjusted. Finally, the adjustable bracket is installed in the sleeve 6 at the specified axial position, and then the temperature recorder 4 is placed to record the test temperature of the bridge plug 5. By recording the actual temperature inside the sleeve 6, more accurate data information is provided to the R&D personnel.

[0047] The adjustable bracket for the recorder described in this embodiment utilizes the magnetic attraction of the base 1 to the inner wall of the sleeve 6, allowing the axial position of the base 1 within the sleeve 6 to be changed. Figure 3 (in the left and right directions), the adjusting stud 2 is threaded into the vertically arranged adjusting screw hole 11 provided in the base 1, and the adjusting stud 2 is threaded to one side of the mounting plate 3, so that the height of the mounting plate 3 can be adjusted by rotating the adjusting stud 2.

The adjustable support for the recorder in the embodiment is mainly used for the installation of the temperature recorder 4, and the installation direction, vertical height and axial position in the sleeve 6 of the temperature recorder 4 are adjusted. When the length of the mounting plate 3 in the radial direction of the adjusting stud 2 and towards the cantilever side meets the size of the axial center of the bridge plug 5, the temperature recorder 4 can be completely arranged at the center position of the bridge plug 5 in the sleeve 6, so that the actual temperature is higher than the preset value due to the “self-heating” caused by the material dissolution in the sleeve 6, and the influence on the data accuracy is reduced.
