DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model.

[0022] Please refer toFigures 1-5 The utility model provides a high accuracy temperature sensor technical scheme: a high accuracy temperature sensor, including sensor body 1, sensor body 1 includes installation end 11, detection end 12 and adjustment end 13, the bottom of installation end 11 is equipped with installation cylinder 14, adjustment end 13 is located in installation cylinder 14, sliding fit between adjustment end 13 and installation cylinder 14, detection end 12 is located at the bottom position of adjustment end 13, installation cylinder 14 is equipped with the locking fixed structure 2 of locking adjustment end 13.

[0023] Installation end 11 is used to install sensor body 1, and detection end 12 is used to detect temperature.

[0024] In the embodiment, referring to Figure 2 As shown in the figure, the adjustment end 13 is a cylindrical barrel, the cylindrical barrel is a hollow structure, the cylindrical barrel is equipped with a reset spring 10, the two ends of the reset spring 10 are respectively equipped with an upper mounting circular block 101 and a lower mounting circular block 102, the upper mounting circular block 101 is connected to the bottom of the installation end 11, and the lower mounting circular block 102 is located at the inner position of the cylindrical barrel.

[0025] During the downward movement of the cylindrical barrel, the position of the detection end 12 is moved downward, and the reset spring 10 is stretched and elongated, after completing a detection, the locking knob 24 is released, the cylindrical barrel is moved upward to the initial position through the reset of the reset spring 10, so as to adjust the position of the detection end 12 next time.

[0026] In the embodiment, referring to Figure 3 As shown in the figure, the side wall of the installation cylinder 14 is equipped with a through slot 141, the outer side wall of the installation cylinder 14 and located on the side of the through slot 141 is equipped with a numerical annotation 142, and the side wall of the sliding block 21 and located on one side of the numerical annotation 142 is equipped with an indicating arrow 25.

[0027] During the adjustment of the detection end 12 according to needs, the indicating arrow 25 moves on the numerical annotation 142, and the operator can accurately adjust the detection end 12 to the required position or value according to the position of the arrow; when the detection end 12 is operated, the arrow immediately moves on the numerical annotation 142, to provide real-time feedback for the operator; this enables the operator to adjust the operation strength and direction in time according to the feedback, to avoid excessive adjustment or adjustment out of position, so that the position is more accurate during the adjustment of the detection end 12.

[0028] In the embodiment, referring to Figure 5As shown, the locking fixing structure 2 comprises a sliding block 21 fixedly connected to the outer wall of the cylindrical barrel, two sliding blocks 22 are arranged at the two ends of the sliding block 21, the sliding block 21 slides up and down in the through groove 141 through the two sliding blocks 22, an arc-shaped block 23 is arranged on the sliding block 21, the arc-shaped block 23 is in sliding fit with the outer wall of the mounting barrel 14, and a locking knob 24 is arranged on the arc-shaped block 23; a push rod 26 is arranged on the sliding block 21.

[0029] When the position of the detection end 12 is adjusted or regulated, the locking knob 24 is loosened, and then the push rod 26 is pulled downward to move the sliding block 21 downward in the through groove 141 through the two sliding blocks 22, the sliding block 21 moves downward while driving the position of the indicating arrow 25 to move, and when the sliding block 21 is moved to the position of the specified numerical annotation 142, the detection end 12 is in the position to be detected at this time, and then the locking knob 24 is tightened to fix the position of the detection end 12, so that the temperature detection work can be carried out.

[0030] When detection is carried out through the sensor body 1, the position of the detection end 12 can be adjusted at any time, and the temperature at different positions can be accurately measured. In some large equipment or complex environment, the temperature at different positions may be different. For example, in an industrial furnace, the temperature distribution of the upper part and the lower part is uneven, and by adjusting the up-down position of the temperature sensor detection end 12, the temperature at a specific position can be accurately measured to provide accurate data for process control. Adapt to temperature gradient change: In an environment with obvious temperature gradient, such as a high refrigeration warehouse, the temperature of the upper and lower layers is different. The up-down adjustment of the detection end 12 can make the sensor better adapt to such gradient change, and obtain accurate temperature value at the height that needs to be concerned, avoiding that the fixed position leads to that the measurement result cannot reflect the actual situation.

[0031] Avoid local interference: There may be local heat sources or heat dissipation areas inside the equipment, and if the position of the sensor detection end 12 is fixed, it may be disturbed by these local factors. By adjusting up and down, the position with the least disturbance can be found to ensure that the measurement result truly reflects the overall temperature condition.

[0032] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
