[0030] Please refer to Figures 1 to 4 The embodiment of the application provides a detection equipment for adjacent cover plate height difference, which comprises a first ruler 1, a second ruler 2 and a sliding hinge part 3. The middle part of the first ruler 1 is provided with a through slot 11. The middle part of the second ruler 2 is provided with a sliding groove 21, and the second ruler 2 and the first ruler 1 are overlapped with each other, and the second ruler 2 and the first ruler 1 are both provided with scales 4. The sliding hinge part 3 is arranged between the first ruler 1 and the second ruler 2, and the sliding hinge part 3 is used for slidingly connecting the first ruler 1 and the second ruler 2.

[0031] The detection equipment for adjacent cover plate height difference provided by the utility model, when detecting, the first ruler 1 is close to the top surface of the higher side cover plate, and the second ruler 2 is slid to be close to the top surface of the adjacent cover plate, the height difference between the adjacent two cover plates is measured by reading the scale 4 of the second ruler 2 under the first ruler 1. And because the first ruler 1 and the second ruler 2 are slidingly connected (that is, the first ruler 1 and the second ruler 2 can not only slide relative to each other, but also rotate relative to each other), therefore, when the measurement is completed, the first ruler 1 and the second ruler 2 can be relatively rotated to fold, so as to completely overlap (as shown in Figure 4 Fig. 3), so as to facilitate the carrying and storage of the detection equipment.

[0032] In one embodiment, the sliding hinge part 3 comprises a first connecting block 31 and a second connecting block 32. The first connecting block 31 is slidingly fitted in the sliding groove 21 of the second ruler 2. The second connecting block 32 is slidingly fitted in the through slot 11 of the second ruler 2, and the second connecting block 32 is connected with the first connecting block 31. The cross section of the first connecting block 31 and / or the second connecting block 32 is circular. By making the cross section of the first connecting block 31 and / or the second connecting block 32 circular, the first ruler 1 / second ruler 2 can be rotated and adjusted around the sliding hinge part 3, so as to facilitate the unfolding and folding of the first ruler 1 and the second ruler 2.

[0033] In one embodiment, the second connecting block 32 is a threaded rod, and the end of the second connecting block 32 is threaded out of the through slot 11 of the second connecting block 32; the sliding hinge 3 further comprises a wing nut 33, which is threadedly fitted to the end of the second connecting block 32. The wing nut 33 can prevent the first ruler 1 from being loosened from the second connecting block 32, thereby causing the first ruler 1 to be separated from the second ruler 2. The wing nut 33 can also be manually tightened to lock the included angle and relative position between the first ruler 1 and the second ruler 2, thereby facilitating measurement. In addition, the wing nut 33 can be manually loosened to separate the first ruler 1 from the second connecting block 32, so that the first ruler 1 can be used alone. The entire disassembly and locking / unlocking process does not require the use of other tools, and is quick and convenient.

[0034] In one embodiment, the second ruler 2 is provided with a sunken platform 22 on the side close to the first ruler 1, and the scale 4 of the second ruler 2 is arranged on the sunken platform 22. As shown in Figure 2 The sunken platform 22 can keep a certain distance between the scale 4 on the second ruler 2 and the first ruler 1, so that the first ruler 1 does not directly rub against the scale 4 on the second ruler 2 when the first ruler 1 and the second ruler 2 slide or rotate relative to each other, thereby protecting the scale 4 of the second ruler 2 from being worn by the first ruler 1.

[0035] In one embodiment, the first ruler 1 and the second ruler 2 are both made of stainless steel. The first ruler 1 and the second ruler 2 made of stainless steel have good corrosion resistance and wear resistance, so that the detection device in this embodiment is not prone to rust and wear during use, thereby prolonging the service life of the detection device.

[0036] In one embodiment, the scale 4 of the first ruler 1 and the second ruler 2 is a laser-engraved scale 4, to ensure the clarity and durability of the scale 4.

[0037] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the present application.
