Description

Technical Field

[0001] The utility model relates to the field of measuring tools, in particular to a longitudinal seam welding inspection ruler. Background Art

[0002] Welding quality inspection is to ensure the integrity, reliability, safety and usability of the welded structure. In addition to the requirements for welding technology and welding process, welding quality inspection is also an important part of the quality management of welded structures.

[0003] Appearance inspection is an important part of welding quality inspection, which includes size inspection, geometric shape inspection, surface flaw inspection, etc. However, the existing longitudinal seam welding inspection rulers can only measure horizontal surfaces, and the same ruler cannot be applied to a variety of different welding surfaces. As a result, the applicability is not very strong and the effect of use is also very single. If you carry multiple inspection rulers for measuring different welding surfaces, it is very inconvenient and not conducive to the convenience of measurement. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a longitudinal seam welding inspection ruler, which aims to improve the problem that the existing longitudinal seam welding inspection ruler has a relatively single measuring object and can often only measure one welding surface.

[0009] Furthermore, a second slide plate is fixedly connected to one side of the outer wall of the main board, and a first slide plate is fixedly connected to one side of the outer wall of the replacement plate.

[0010] The above technical solution facilitates the movement of the measuring ruler.

[0011] Furthermore, one side of the outer wall of the slide plate 1 and the slide plate 2 is respectively fixedly connected with an acrylic plate.

[0012] The above technical solution makes it easier to observe the degree of the measuring ruler.

[0013] Furthermore, a measuring ruler is slidably connected inside the second slide plate, and the measuring ruler is slidably connected inside the first slide plate.

[0014] Through the above technical solution, the movement trajectory of the measuring ruler is limited, which facilitates the measurement accuracy.

[0015] Furthermore, two sliding holes are opened on both sides of the second slide plate, and two locking balls are arranged on both sides of the second slide plate. The two locking balls are slidably connected inside the second slide hole.

[0018] Through the above technical solution, the second card ball can be reset while moving.

[0019] Furthermore, an anti-slip groove is provided on one side of the outer wall of the measuring ruler, and limiting grooves are provided on both sides of the inside of the measuring ruler.

[0020] Through the above technical solution, the anti-skid groove facilitates the operation of the measuring ruler, and the limiting groove allows the measuring ruler to slide normally, and the limiting groove is for the second card ball to slide.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, firstly, the replacement plate can be disassembled on the main board, the sleeve is inserted into the jack, the fixing column is inserted into the sleeve, and then the card ball is pushed out by the action of the spring and is stuck into the card slot, so that the replacement plate can be disassembled at the bottom of the main board, which solves the problem that the inspection ruler can only measure a single welding surface, and achieves the effect of being able to inspect both the arc welding surface and the horizontal welding surface.

[0023] 2. In the utility model, firstly, the measuring ruler can be slid by the slide plate 1 and the slide plate 2, and the spring 2 can push the card ball 2 out of the slide hole 2, so that the measuring ruler can only slide through the limit groove, and the spring 2 facilitates the removal of the measuring ruler, so that the measuring ruler can be replaced as needed.

[0033] Specifically, the main board 1 and the replacement board 2 can be spliced ​​as a whole or used separately, so that the inspection ruler can inspect both the arc welding surface and the horizontal welding surface. A socket 7 is provided at the bottom of the main board 1, which can be inserted and fitted by the sleeve 6 at the top of the replacement board 2. When the sleeve 6 is inserted into the socket 7, the fixing column 10 will also be inserted into the sleeve 6 and complete the fixation. A conical block 12 is provided on the top of the fixing column 10 to facilitate pushing the card ball 9 back into the sliding hole 18. After it is fully inserted, the elastic force of the spring 8 can make the card ball 9 extend out of the sliding hole 18. At this time, the card slot 11 is level with the card ball 9, and the card ball 9 will be stuck in the card slot 11, so that the main board 1 and the replacement board 2 are fixed.

After the fixing column 10 is inserted, the card ball 9 can be made to protrude out of the sliding hole 18 again under the action of the spring 8, and then snap into the card slot 11 corresponding to its position, thereby fixing the main board 1 and When replacing the plate 2, when the replacement plate 2 is fixed, the horizontal welding surface can be inspected, and when the replacement plate 2 is removed, the arc welding surface can be inspected. When replacing the measuring scale bar 5, the measuring scale bar 5 can be inserted into the interior of the slide groove plate 2 4. Under the action of pressure, the second card ball 16 will overcome the force of the second spring 15 and retract into the second slide hole 19, so that the measuring scale bar 5 can be inserted into the interior of the slide groove plate 2 4. After insertion, the limiting groove 17 will allow the second card ball 16 to normally extend out of the second slide hole 19, thereby not interfering with the sliding of the measuring scale bar 5.
