[0024] The specific implementation of the present application is described in detail below with reference to the accompanying drawings.

[0025] Embodiment 1: A gap measuring vernier feeler gauge, referring to Figure 1 , including a base 2 and a ruler 1 arranged on the base 2, the ruler 1 is wedge-shaped, a cursor slider 3 is provided on the inclined surface of the ruler 1, U-shaped grooves 4 are provided on both sides of the ruler 1, and both sides of the cursor slider 3 are slidably connected in the U-shaped grooves 4.

[0026] You can place the tip of the wedge ruler ( Figure 1 When measuring the gap, the tip of the wedge-shaped ruler is inserted into the gap until it cannot be inserted any further, at which time the slider 3 is pushed upward, and the gap width can be obtained according to the position of the slider 3.

[0027] The inclined surface of the ruler body 1 is provided with a scale or scale lines 5 for reading. In particular, the reading indicated by the scale or scale lines 5 is set as the corresponding gap width value.

[0028] refer to Figure 1-2 The base body 2 is provided with a distance measuring module 7 and a display module 6. The distance measuring module 7 is arranged at the tail end of the inclined surface of the ruler body 1 and faces the cursor slider 3. The distance measuring module 7 is used to detect the distance between the distance measuring module 7 and the cursor slider 3. The distance measuring module is any one of a laser distance measuring module, an infrared distance measuring module and an ultrasonic distance measuring module.

[0029] The display module 6 is used to display the measurement results. In this embodiment, the display module 6 is a display screen.

[0030] A main control unit and a power module are arranged in the base 2. The main control unit receives data from the distance measuring module 7 and controls the display module 6 to display the measurement result. In this embodiment, the main control unit is a single chip microcomputer and the power module is a battery.

[0031] The base body 2 is also provided with a voice module, which is connected to the main control unit and is used for voice broadcasting of measurement results.

[0032] The base body 2 is also provided with a key module including a plurality of keys, wherein the key module at least includes a power key and a start key, and the start key is used to control the distance measuring module 7 to perform measurement.

[0033] A storage module is provided in the base body 2 for saving the measurement results, and storing the maximum value in a single measurement process, which is beneficial for data tracing.

[0034] The principle of gap width measurement is as follows Figure 3As shown, assume that the distance from the distance measuring module 7 to the leftmost end of the vernier slider 3 is L, the maximum height value of the wedge-shaped feeler gauge is H, and the wedge angle value of the feeler gauge is a, wherein the maximum height value H of the wedge-shaped feeler gauge and the wedge angle value a of the feeler gauge are design values ​​and are known in a certain ruler body 1. Therefore, the gap width h=H-sina*L.

[0035] In particular, the distance L from the distance measuring module 7 to the leftmost end of the cursor slider 3 is the sum of the data measured by the distance measuring module 7 and the width of the cursor slider 3 .

[0036] The wedge angle value a of the feeler gauge is in the range of 15-30°, and the maximum height value H of the wedge feeler gauge is in the range of 20-30 mm.

[0037] When using the gap measuring vernier feeler gauge to measure the gap width, there is no need for manual reading. The measured values ​​can be automatically displayed, voice broadcasted, and automatically stored, which greatly reduces the labor intensity of the measurement personnel and improves work efficiency. In the case of insufficient power supply, it can also be used as a regular feeler gauge and read visually, achieving dual purposes of one gauge.

[0040] By combining two gap measuring vernier feeler gauges, the measuring range can be increased without increasing the wedge angle of the gauge body, thereby improving the scope of use.
