Detailed Description of the Embodiments

[0022] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0023] As Figures 1 to 2 shown, the full-automatic intelligent drawing type adhesion test device of the present invention includes a toe tip 1, a rod body 2, a telescopic rod one 5, a telescopic rod two 8, and a telescopic rod three 11; the rod body 2 includes a distance measuring host 3, a rod body fixing knob 4, and a level bubble 12; the telescopic rod one 5 includes a distance measuring component one 6 and a telescopic rod fixing knob one 7; the telescopic rod two 8 includes a distance measuring component two 9 and a telescopic rod fixing knob two 10.

[0024] Specifically, depth gauges are provided on the telescopic rods, which can provide accurate length information for the distance measuring host 3, the distance measuring component one 6, and the distance measuring component two 9, and can also prevent relative rotation. The length information measured by the distance measuring component one 6 and the distance measuring component two 9 can be transmitted wirelessly to the distance measuring host 3, and the distance measuring host 3 displays the detailed length information.

[0025] Among them, the distance measuring host 3, the distance measuring component one 6, and the distance measuring component two 9 all adopt grating electronic displacement gauges. Specifically, the model of the distance measuring component is a general large stroke 1000 - 1500 mm type grating scale, and the accuracy is 0.1 mm; in addition, the distance measuring component one 6 and the distance measuring component two 9 are respectively connected to the control panel of the distance measuring host 3 by Bluetooth.

[0026] In one embodiment, length information is engraved on the rod surfaces of the telescopic rod one 5, the telescopic rod two 8, and the telescopic rod three 11, and the clearance can be manually measured through the elongation of the telescopic rods.

[0027] In addition, the rod body is equipped with a level bubble 12. When measuring, keeping the bubble centered can measure the clearance height of the road sign board more accurately. The level bubble 12 can be replaced by other levels, such as a bar level, a frame level, an optical-mechanical level, an electronic level, a laser level, etc.

[0028] The following briefly describes the working principle and working process of the traffic sign clearance detection device of the present utility model.

[0029] As Figure 1 shown, retract the telescopic rod one 5, the telescopic rod two 8, and the telescopic rod three 11 into the rod body 2. When it is retracted to the minimum, turn on the distance measuring host 3. The distance measuring component one 6 and the distance measuring component two 9 can be adjusted to "zero" with one key through the distance measuring host 3, or can be adjusted to "zero" separately. After adjusting to "zero", add the length from the bottom of the toe tip 1 to the top of the telescopic rod three 11, which is the fully retracted length, on the operation page of the distance measuring host 3. After setting, stand the toe tip 1 directly below the sign board and adjust the rod body to make the bubble in the level bubble 12 centered.

[0030] As Figure 2As shown, extend the telescopic rod III 11. During the extension of the telescopic rod III 11, the distance measuring component II 9 automatically measures the extended length of the telescopic rod III 11 and transmits the data to the distance measuring host 3. After the telescopic rod III 11 is fully extended, tighten the telescopic rod fixing knob II 10.

[0031] Extend the telescopic rod II 8. During the extension of the telescopic rod II 8, the distance measuring component I 6 automatically measures the extended length of the telescopic rod II 8 and transmits the data to the distance measuring host 3. After the telescopic rod II 8 is fully extended, tighten the telescopic rod fixing knob I 7.

[0032] Extend the telescopic rod I 5. During the extension of the telescopic rod I 5, the distance measuring host 3 automatically measures the extended length of the telescopic rod I 5. When the telescopic rod I 5 extends to the bottom of the sign board, tighten the rod body fixing knob 4. The distance measuring host 3 records the cumulative length in real time. At this time, the cumulative length measured by the distance measuring host 3 is the clearance of the current sign board.

[0033] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
