[0002] Pointer-type instruments are widely used in daily life. Examples include mechanical thermometers and hygrometers for measuring environmental conditions, and aneroid barometers for measuring atmospheric pressure. These instruments use different sensing elements to achieve equilibrium with the current ambient temperature, humidity, or atmospheric pressure, indicating the current value through pointer movement. When taking a reading, the position indicated by the pointer is estimated, leading to significant human error. Currently, the most widely used method is image recognition. This method uses an image acquisition and recognition device to obtain a precise image of the instrument's dial area based on the relative position of the device. Image recognition processing is then performed on the instrument to read the dial value. This method is simple and fast, but costly, requiring high-definition cameras and compatible recognition software. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0026] Example 1:

[0027] like Figure 1 and Figure 3 As shown, this utility model proposes an auxiliary reading device for pointer-type instruments, including a resistor ring 3, a sliding rod 4, and a sliding laser 5. The inner ring of the resistor ring 3 is provided with an annular groove. Two sliding rods 4 are provided, and one end of each sliding rod 4 is respectively installed in the annular groove and slidably disposed in the annular groove. The sliding laser 5 is slidably mounted on the sliding rod 4 by fastening knobs 9.

[0028] It also includes a fixing rod 6, one end of which is fixed to the upper surface of the resistor ring 3, and the other end is located at the center point of the resistor ring 3. A fixed laser 61 is fixed to the end of the fixing rod 6. The fixed laser 61 is located at the center point of the resistor ring 3. The sliding laser 5 and the fixed laser 61 are connected to each other. The sliding laser 5 and the fixed laser 61 are always set perpendicular to the plane. The pointer-type instrument panel is placed parallel to the resistor ring 3 directly below. The center and tail of the pointer, the upper limit and the lower limit of the disk scale of the pointer-type instrument panel are coated with laser reaction material.

[0029] It also includes a display 7, which is connected to a resistor ring 3;

[0030] It also includes a telescopic rod 2 and a base frame 10. The telescopic rod 2 includes a base 21 and a telescopic arm 22. The telescopic arm 22 is mounted on the base 21. The base 21 is provided with a knob 23 for controlling the extension and retraction of the telescopic arm 22. The top of the telescopic arm 22 is fixed on a resistor ring 3. The base frame 10 and the resistor ring 3 are concentric circles. The base 21 of the telescopic rod 2 is fixed on the base frame 10.

[0031] It also includes a display stand 1, which includes an adjuster 11 and a fixing foot 12. An adjustment groove is provided along the height direction of the fixing foot 12. The adjuster 11 is provided with a slot, a fixing hole and a fixing button. The adjuster 11 is snapped onto the base frame 10 through the slot. The fixing foot 12 is inserted into the fixing hole and fixed by inserting the fixing button into the adjustment groove. The pointer-type instrument panel is placed on the fixing foot 12.

[0032] The fixing foot 12 is L-shaped, and the adjustment groove is formed on the side wall of the L-shaped fixing foot 12.

[0033] It also includes levers 8, which are respectively mounted on sliding rods 4. The sliding rods 4 slide within the annular groove by being moved by the levers 8.

[0034] This utility model proposes an auxiliary reading device for pointer-type instruments, including a resistance ring 3, a sliding rod 4, and a sliding laser 5. The inner ring of the resistance ring 3 has an annular groove for the sliding rod 4 to slide. Two sliding rods 4 are provided, with one end of each sliding rod 4 installed in the annular groove and slidably positioned relative to the groove, thus fixing the sliding rod 4. The sliding laser 5 is slidably mounted on the sliding rod 4 via a fastening knob 9. The pointer-type instrument panel is placed parallel to the resistance ring 3 directly below it. The pointer center and pointer tail, as well as the upper and lower limits of the disc scale, are coated with a laser reactive substance. This allows the fixed laser 61 and the sliding laser 5 to react with the laser reactive substance during measurement, causing the laser to light up upon contact with the reactive substance, thus facilitating recording and measurement.

[0035] One end of the fixing rod 6 is fixed to the upper surface of the resistance ring 3, and the other end is located at the center point of the resistance ring 3. The fixing rod 6 is used to fix the fixed laser 61, which is located at the center point of the resistance ring 3. The sliding laser 5 and the fixed laser 61 are connected to each other to realize the measurement. The measured resistance value can be converted into the reading value of the pointer instrument panel. The sliding laser 5 and the fixed laser 61 are always set perpendicular to the plane to prevent deviation during measurement.

[0036] The display 7 is connected to the resistor ring 3 to display the measured final resistance value for easy reading and recording.

[0037] The telescopic rod 2 is installed below the resistor ring 3. It includes a base 21 and a telescopic arm 22. The telescopic arm 22 is installed on the base 21. The base 21 is provided with a knob 23 for controlling the extension and retraction of the telescopic arm 22. The height of the telescopic rod 2 can be adjusted by adjusting the knob 23, thereby adjusting the height of the resistor ring 3. When it is necessary to adjust the height of the telescopic arm 22, the telescopic arm 22 is adjusted to an appropriate height, and the adjustment knob 23 is tightened to press against the telescopic arm 22, thus fixing the telescopic arm 22. By adjusting the telescopic rod 2, it can be ensured that the light emitted by the fixed laser 61 is perpendicular to the center of the resistor ring 3.

[0038] The base frame 10 is used to install and fix the telescopic rod 2, and it is concentric with the resistor ring 3.

[0039] The instrument holder 1 is used to fix and place the pointer-type instrument panel. By adjusting the adjuster 11, it can meet the reading requirements of pointer-type instrument panels of various sizes. The instrument holder 1 includes the adjuster 11 and the fixing foot 12. An adjustment groove is provided along the height direction of the fixing foot 12. The adjuster 11 is provided with a slot, a fixing hole and a fixing button. The adjuster 11 is snapped onto the base frame 10 through the slot. The fixing foot 12 is inserted into the fixing hole and fixed by inserting the fixing button into the adjustment groove. When it is necessary to adjust the height of the base frame 10, the fixing button is released and it is snapped into the adjustment groove of the appropriate height to achieve the height adjustment of the base frame 10.

[0040] The fixing foot 12 is L-shaped, and the connection angle of the L-shaped fixing foot 12 is acute or obtuse. That is, the L-shaped fixing foot 12 can be turned outward or inward. At this time, the fixing hole on the adjuster 11 for fixing the fixing foot 12 is set with a corresponding tilt, which facilitates the installation and adjustment of the fixing foot 12. When the fixing foot 12 is turned outward or inward, the placement area for placing the pointer instrument panel is larger, which can place a large pointer instrument panel and support and fix it.

[0041] The levers 8 are respectively installed on the sliding rods 4. By moving the levers 8, the sliding rods 4 can be slid, thereby moving the sliding laser 5.

[0042] Example 2: As Figure 2 As shown, the connection angle of the L-shaped fixing foot 12 is a right angle, that is, the L-shaped fixing foot 12 is perpendicular to the ground. At this time, the fixing hole on the adjuster 11 for fixing the fixing foot 12 is straight, which facilitates the installation and adjustment of the fixing foot 12. The resulting placement area for placing the pointer instrument panel is small, which can place small or medium pointer instrument panels and achieve support and fixation.

[0043] The present invention discloses a method for using an auxiliary reading device for pointer-type instruments, comprising the following steps:

[0044] S1. Apply laser reactive material to the center and tail of the pointer, as well as the upper and lower limits of the circular scale on the pointer-type instrument panel.

[0045] S2. Position the fixed laser 61 at the center of the resistor ring 3 and perpendicular to the plane. Position the sliding laser 5 at the upper limit and lower limit of the disk scale respectively and make it perpendicular to the plane. Connect the two ends of the sliding rheostat to the sliding laser 5 respectively, and record the resistance at this time as R1.

[0046] S3. During the measurement process, keep the position of the sliding laser 5 at the upper limit of the disk scale stationary, and position it to the end of the pointer by moving the other sliding laser 5 on the moving resistor ring 3. Record the resistance at this time as R2.

[0047] S4. Calculate the final reading. The final reading is... Where T 读 This indicates that the fixed laser 6 on the pointer-type instrument panel points to the reading on the pointer-type instrument panel, T. 上限 T represents the upper limit reading of the pointer-type instrument panel indicated by the sliding laser 5. 下限 This indicates the reading of the lower limit of the pointer-type instrument panel indicated by the sliding laser 5.

[0048] This invention ensures that the three lasers are always perpendicular to the dial, thus achieving higher accuracy during measurement. The fixed laser 61 at the center of the resistance ring 3 is fixedly installed, while the sliding laser 5 on the resistance ring 3 can interact in a ring. The fixed laser 61 and the sliding laser 5 on the resistance ring 3 are interconnected.

[0049] This invention, through the telescopic rod 2, effectively ensures that the light emitted by the fixed laser 61 is perpendicular to the center of the pointer. The outer base 10, via the telescopic rod 2, can accommodate readings from pointer dials of various sizes.

[0050] In this invention, the sliding laser 5 on the resistor ring 3 is used to measure the resistance value. The measured resistance value can be converted into a dial reading and displayed on the display 7, making it more convenient for staff to observe.

[0051] Based on the above structure, this utility model has low manufacturing cost, high accuracy, and simple operation, and is worth promoting and using.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
