Description

Technical Field

[0001] The present invention belongs to the technical field of steel structure detection equipment, and specifically relates to a steel structure detection equipment. Background Technique

[0002] After the steel structure is welded, in order to ensure the quality of the welded joint and meet the design requirements, a welding inspection ruler needs to be used for measurement. The welding inspection ruler is used to measure the weld height, weld width, weld angle, weld surface flatness, and the length and position of the welded joint at the welded part of the steel structure.

[0003] After the welding operation of the steel structure is completed, there are often impurities such as welding slag, oil stains, and oxides at the welded joint. These impurities need to be removed in time before measurement, otherwise it will affect the subsequent measurement accuracy. However, the traditional welding inspection ruler itself does not have a mechanism for cleaning impurities such as welding slag, resulting in the need to carry cleaning tools when removing welding slag and other impurities, which is not convenient to carry when measuring multiple points, and at the same time will lead to low measurement efficiency.

[0004] Therefore, the present invention provides a steel structure detection equipment and method. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background technique.

[0007] Furthermore, a spraying component is arranged inside the fixed frame, and the spraying component includes two liquid storage boxes symmetrically and fixedly installed inside the fixed frame. A liquid outlet pipe that is fixedly installed at the bottom of the liquid storage box and is connected to the inside and is equipped with a one-way valve. Hollow bottom plates are fixedly installed on both sides of the fixed frame. A number of holes that are connected to the inside are opened at the bottom of the bottom plate. The end of the liquid outlet pipe away from the liquid storage box is connected to the inside of the bottom plate. A liquid inlet pipe that is connected to the inside and is equipped with a one-way valve is fixedly installed on one side of the liquid storage box.

[0008] Further, an auxiliary component is arranged inside the fixed frame. The auxiliary component includes a number of elastic balls fixedly installed inside the fixed frame. One side of the bottom plate is fixedly installed with a number of connecting pipes, and one end of the connecting pipe is communicated with the inside of the elastic ball.

[0009] Further, two symmetrically arranged guiding plates are fixedly installed inside the connecting pipe, and the guiding plates are arc-shaped.

[0010] Further, a positioning component is arranged on the surface of the sliding rod. The positioning component includes a positioning ring fixedly sleeved on the surface of the sliding rod and made of flexible material, and a positioning groove is formed inside the fixed frame.

[0011] Further, the pressing block is of a hollow design and made of elastic flexible material. A quick-drying mechanism is arranged at the bottom of the pressing block. The quick-drying mechanism includes a communicating pipe communicated with the inside of the pressing block. One end of the communicating pipe is fixedly installed with a connector, and a sealing ring is fixedly sleeved on the surface of the connector. An air spraying pipe made of flexible material is fixedly installed inside the fixed frame, and one end of the air spraying pipe is outside the fixed frame and connected to the communicating pipe.

[0012] Further, a stirring mechanism is arranged inside the pressing block. The stirring mechanism includes a connecting plate fixedly connected to the inner wall of the pressing block. One end of the connecting plate is fixedly installed with a connecting rod. The end of the connecting rod away from the connecting plate is inside the liquid storage box. The connecting rod is in sealed sliding connection with both the pressing block and the liquid storage box. The end of the connecting rod away from the connecting plate is fixedly installed with a pushing plate, and a number of convex platforms are fixedly installed on one side of the pushing plate.

[0013] Further, a limiting mechanism is arranged inside the welding inspection ruler. The limiting mechanism includes a number of storage grooves formed inside the welding inspection ruler. A sealing plate is hermetically slidably connected to the inside of the storage groove through a second spring. One end of the sealing plate is fixedly installed with a magnetic block. A docking pipe communicated with the inside of the storage groove is installed on one side of the welding inspection ruler, and one end of the docking pipe is connected to the communicating pipe. Both the height ruler and the undercut depth ruler are made of metal.

[0014] Further, a limiting plate is fixedly installed inside the storage groove. A cylinder on the sealing plate is slidably connected to the limiting plate. A convex block made of rubber is fixedly installed on one side of the sealing plate, and the convex block gradually increases from the end close to the sealing plate to the end away from the sealing plate. A groove adapted to the convex block is formed on one side of the limiting plate.

[0015] A detection method using the above steel structure detection equipment includes the following steps: S1: Slide the sliding rod, causing the sliding rod to drive the fixing plate and the sandpaper to move towards the welding area. Make the positioning ring on the surface of the sliding rod snap into the positioning groove of the fixed frame for temporary fixation. The sandpaper contacts the steel structure welding area, and then rotate the sliding rod to drive the fixing plate and the sandpaper to rotate, so that after rotating the fixing plate and the sandpaper by 90°, they contact the steel structure welding area again. S2: When the sliding rod moves, it continuously squeezes the liquid storage box with the fixing plate, causing the pre-stored cleaner in the liquid storage box to enter the bottom plate through the liquid outlet pipe and then spray out through the holes at the bottom of the bottom plate. S3: When using the welding inspection ruler for measurement, the gas in the pressing block enters the storage groove and pushes the sealing plate with the gas, causing the sealing plate to slide out of the storage groove with the magnetic block.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. For the steel structure detection equipment and method of the present invention, by sliding the sliding rod, the sliding rod drives the fixing plate and the sandpaper to move towards the welding area, exposing the sandpaper from the fixed frame, and making the positioning ring on the surface of the sliding rod snap into the positioning groove of the fixed frame for temporary fixation, thus facilitating the removal of impurities such as welding slag on the steel structure welding area by the sandpaper. When there is too much welding slag at the steel structure welding area, by rotating the sliding rod, the sliding rod drives the fixing plate and the sandpaper to rotate, thereby rotating the fixing plate and the sandpaper by 90°, and then changing the vertical fixing plate and sandpaper into a horizontal one, which can more efficiently remove impurities such as welding slag on the steel structure. Through the designed structure, it can quickly clean the residual welding slag on the surface when measuring the steel structure welding area, and there is no need to carry additional cleaning equipment. While achieving high integration, it also has the advantages of being easy to carry and operate, and greatly improving the measurement efficiency of the measurement personnel.

[0018] 2. For the steel structure detection equipment and method of the present invention, through the designed spraying component, the pre-stored cleaner in the liquid storage box enters the bottom plate through the liquid outlet pipe and then sprays out through the holes at the bottom of the bottom plate, so that before the sandpaper contacts the welding slag, the fixing plate first squeezes and sprays the cleaner towards the welding slag, making impurities such as welding slag become soft, thus cooperating with the subsequent removal of welding slag by the sandpaper. The designed auxiliary component uses the fixing plate to squeeze the elastic ball, squeezing the gas in the elastic ball into the connecting pipe, and guiding the gas to all around through the arc-shaped guide plate in the connecting pipe. Thus, after completing the cleaning work of the welding slag, the residual liquid on the surface can be quickly dried by the gas, which is convenient for subsequent measurement of the welding joint of the steel structure using the welding inspection ruler. The designed quick-drying mechanism can use the gas in the pressing block to assist in drying the bottom of the sandpaper, thereby preventing the cleaning liquid from damaging the sandpaper and improving the utilization rate of the sandpaper. And at this time, using the pressing block made of anti-slip material is also convenient for holding the fixed frame and the welding inspection ruler tightly for measurement.

[0019] 3. For a steel structure detection device and its method according to the present invention, since the pressing block is made of a flexible material, it will drive the connecting plate and the connecting rod to move towards the liquid storage box. When the connecting rod moves, it will drive the push plate and several convex platforms to move together, and use the push plate and the convex platforms to stir the cleaning agent in the liquid storage box, thereby effectively preventing the precipitation of the cleaning agent after long-term non-use, which may lead to poor use effects. Since the pressing block is made of an elastic material, when not being extruded, it will drive the connecting plate, the connecting rod and the push plate to reset, thus not affecting the subsequent extrusion of the liquid storage box by the fixing plate.

[0020] 4. For a steel structure detection device and its method according to the present invention, when one end of the height gauge and the root penetration depth gauge contacts the steel structure and measures, press the pressing block, so that the gas in the pressing block enters the storage groove, and use the injected gas to push the sealing plate, so that the sealing plate drives the magnetic block to slide out of the storage groove, and the magnetic block adsorbs to the height gauge or the root penetration depth gauge made of metal material, thereby temporarily fixing the height gauge or the root penetration depth gauge, and then facilitating the measurement personnel to take readings. And the second spring causes the sealing plate not to reset quickly, thus playing a role of delaying reset, which is convenient for the staff to confirm the value after the initial reading. Through the structure designed above, the function of quickly fixing the height gauge and the root penetration depth gauge is realized, which is not as cumbersome and inefficient as the traditional knob style.

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] As Figures 1 to 9 shown, a steel structure detection device according to an embodiment of the present invention includes a welding inspection ruler 1. A height ruler 2 and an undercut depth ruler 3 are slidably connected to the welding inspection ruler 1. A multi-purpose ruler 4 is rotatably connected to a surface of the welding inspection ruler 1 away from the height ruler 2. A cleaning mechanism 10 is provided on a surface of the welding inspection ruler 1 close to the multi-purpose ruler 4. The cleaning mechanism 10 includes a hollow fixed frame 11 fixedly connected to the welding inspection ruler 1. A sliding rod 12 is slidably connected to a top of the fixed frame 11. A bottom of the sliding rod 12 is fixedly installed with a fixed plate 13 located inside the fixed frame 11. A sandpaper 14 is installed at a bottom of the fixed plate 13. A first spring 15 is fixedly installed between the fixed plate 13 and the fixed frame 11. Pressing blocks 16 made of anti-slip material are fixedly installed on two sides of the fixed frame 11. A positioning assembly 19 is provided on a surface of the sliding rod 12. The positioning assembly 19 includes a positioning ring 191 made of flexible material and fixedly sleeved on the surface of the sliding rod 12. A positioning groove 192 is formed inside the fixed frame 11.

[0034] During operation, when using the welding inspection ruler 1 to detect the joint 22 of the steel structure, by gripping the pressing blocks 16 on both sides of the fixed frame 11, it is convenient to pick up the welding inspection ruler 1 for use. When the welding inspection ruler 1 approaches the welding area, by sliding the sliding rod 12, the sliding rod 12 drives the fixed plate 13 and the sandpaper 14 to move towards the welding area, so that the sandpaper 14 is exposed from the fixed frame 11, and the positioning ring 191 on the surface of the sliding rod 12 is snapped into the positioning groove 192 of the fixed frame 11 for temporary fixation. At this time, the sliding rod 12, the fixed plate 13 and the sandpaper 14 will not reset under the action of the first spring 15, which is convenient for the sandpaper 14 to grind and remove impurities such as welding slag at the welding area of the steel structure. When there is too much welding slag at the welding area of the steel structure, by rotating the sliding rod 12, the sliding rod 12 drives the fixed plate 13 and the sandpaper 14 to rotate, so as to rotate the fixed plate 13 and the sandpaper 14 by 90°, and then turn the vertical fixed plate 13 and sandpaper 14 into horizontal, which can more efficiently remove impurities such as welding slag on the steel structure. By using the positioning ring 191 to enter the positioning groove 192, the fixed plate 13 is not easily reset under the action of the first spring 15. At the same time, due to the friction between the positioning ring 191 and the positioning groove 192, the rotated sliding rod 12 will not be affected by the first spring 15 and reset.

[0035] Through the structure designed above, it can quickly clean the residual welding slag on the surface when measuring the welding area of the steel structure, and there is no need to carry additional cleaning equipment. While achieving high integration, it also has the advantages of being easy to carry and convenient to operate, and greatly improves the measurement efficiency of the measurement personnel.

[0036] A spraying component 17 is arranged in the fixed frame 11. The spraying component 17 includes two liquid storage boxes 171 symmetrically and fixedly installed in the fixed frame 11. The bottom of the liquid storage box 171 is fixedly installed with a liquid outlet pipe 172 that is connected to the inside and has a one-way valve. Hollow bottom plates 173 are fixedly installed on both sides of the fixed frame 11. A number of holes communicating with the inside are opened at the bottom of the bottom plate 173. One end of the liquid outlet pipe 172 away from the liquid storage box 171 is connected to the inside of the bottom plate 173. One side of the liquid storage box 171 is fixedly installed with a liquid inlet pipe that is connected to the inside and has a one-way valve.

[0037] Specifically, an auxiliary component 18 is arranged in the fixed frame 11. The auxiliary component 18 includes a number of elastic balls 181 fixedly installed in the fixed frame 11. A number of connecting pipes 182 are fixedly installed on one side of the bottom plate 173. One end of the connecting pipe 182 is connected to the inside of the elastic ball 181. Two symmetrically arranged guide plates 183 are fixedly installed in the connecting pipe 182. The guide plates 183 are arc-shaped.

[0038] Specifically, the pressing block 16 is designed to be hollow and made of elastic flexible material. A quick-drying mechanism 20 is provided at the bottom of the pressing block 16. The quick-drying mechanism 20 includes a connecting pipe 21 communicating with the inside of the pressing block 16. One end of the connecting pipe 21 is fixedly installed with a connector 22, and a sealing ring 23 is fixedly sleeved on the surface of the connector 22. A flexible material jet pipe 24 is fixedly installed inside the fixed frame 11, and one end of the jet pipe 24 is outside the fixed frame 11 and connected to the connecting pipe 21.

[0039] During operation, when the sliding rod 12 drives the fixed plate 13 to move, both sides of the fixed plate 13 will continuously squeeze the liquid storage box 171, so that the pre-stored cleaning agent (which can be a water-based cleaning solution or an alcohol solvent, selected according to the actual situation) in the liquid storage box 171 enters the bottom plate 173 through the liquid outlet pipe 172 and is then sprayed out through the holes at the bottom of the bottom plate 173. Thus, before the sandpaper 14 contacts the welding slag, the fixed plate 13 first squeezes and sprays the cleaning agent towards the welding slag, making impurities such as welding slag become soft, so as to cooperate with the subsequent removal of the welding slag by the sandpaper 14. It should be noted that the design of the bottom plate 173 and the opening of several holes at the bottom are to increase the spraying area, so as to better remove the welding slag. And when sliding the sliding rod 12, the staff's hand holds the fixed frame 11 and no longer presses the pressing block 16.

[0040] When the fixed plate 13 drives the sandpaper 14 to complete the work of removing the welding slag, it will reset into the fixed frame 11. At this time, the elastic ball 181 is squeezed by the fixed plate 13, and the gas in the elastic ball 181 is squeezed into the connecting pipe 182 and guided to all around through the arc-shaped guide plate 183 in the connecting pipe 182. Thus, after the welding slag cleaning work is completed, the gas is used to quickly dry the remaining liquid on the surface, so as to facilitate the subsequent measurement of the welding joint 22 of the steel structure by the welding inspection ruler 1.

[0041] After the fixed plate 13 resets into the fixed frame 11, press the pressing block 16 again. The gas in the pressing block 16 will enter the jet pipe 24 through the connecting pipe 21 and blow towards the bottom surface of the sandpaper 14 (one end of the connecting pipe 21 is connected to the jet pipe 24 in the initial state and is sealed by the sealing ring 23 to prevent air leakage). The gas in the pressing block 16 is used to assist in drying the bottom of the sandpaper 14, so as to prevent the cleaning liquid from damaging the sandpaper 14, and thus improve the utilization rate of the sandpaper 14. And at this time, the pressing block 16 made of anti-slip material is also convenient for holding the fixed frame 11 and the welding inspection ruler 1 for measurement.

[0042] A stirring mechanism 30 is arranged inside the pressing block 16. The stirring mechanism 30 includes a connecting plate 31 fixedly connected to the inner wall of the pressing block 16. One end of the connecting plate 31 is fixedly installed with a connecting rod 32. The end of the connecting rod 32 away from the connecting plate 31 is located inside the liquid storage box 171. The connecting rod 32 is in sealed sliding connection with both the pressing block 16 and the liquid storage box 171. The end of the connecting rod 32 away from the connecting plate 31 is fixedly installed with a pushing plate 33. A plurality of convex platforms 34 are fixedly installed on one side of the pushing plate 33.

[0043] During operation, when the pressing block 16 is pressed for the first time, since the pressing block 16 is made of a flexible material, it will drive the connecting plate 31 and the connecting rod 32 to move towards the liquid storage box 171. When the connecting rod 32 moves, it will drive the pushing plate 33 and a plurality of convex platforms 34 to move together, using the pushing plate 33 and the convex platforms 34 to stir the cleaning agent in the liquid storage box 171, thereby effectively preventing the cleaning agent from precipitating after long-term non-use, resulting in poor use effects. Since the pressing block 16 is made of an elastic material, when not being extruded, it will drive the connecting plate 31, the connecting rod 32 and the pushing plate 33 to reset, thus not affecting the subsequent pressing of the liquid storage box 171 by the fixing plate 13.

[0044] A limiting mechanism 40 is arranged inside the welding inspection ruler 1. The limiting mechanism 40 includes a plurality of storage grooves 41 opened inside the welding inspection ruler 1. A sealing plate 42 is hermetically slidably connected to the inside of the storage groove 41 through a second spring 44. One end of the sealing plate 42 is fixedly installed with a magnetic block 43. A butt joint pipe 45 communicating with the inside of the storage groove 41 is installed on one side of the welding inspection ruler 1. One end of the butt joint pipe 45 is connected to the communicating pipe 21. The height ruler 2 and the undercut depth ruler 3 are both made of metal.

[0045] Specifically, a limiting plate 46 is fixedly installed inside the storage groove 41. The cylinder on the sealing plate 42 is slidably connected to the limiting plate 46. A convex block 47 made of rubber is fixedly installed on one side of the sealing plate 42. The convex block 47 gradually increases from the end close to the sealing plate 42 to the end away from the sealing plate 42. A groove 48 adapted to the convex block 47 is opened on one side of the limiting plate 46.

[0046] During operation, after the welding slag removal work is completed, when the welding inspection ruler 1 is used for measurement, the connecting tube 21 and the air injection tube 24 are pulled out and separated, and the two connecting tubes 21 are respectively inserted into the corresponding butt joint tubes 45, so that the gas generated after pressing the pressing block 16 again will enter the storage groove 41 through the connecting tube 21 and the butt joint tube 45. When one end of the height gauge 2 and the undercut depth gauge 3 are in contact with the steel structure and measured, it is necessary to temporarily fix the depth gauge and the undercut depth gauge 3, so as to facilitate the measurement personnel to read accurately. At this time, the pressing block 16 is pressed, so that the gas in the pressing block 16 enters the storage groove 41 (the gas will only enter the interval of the second spring 44 of the storage groove 41), and the sealing plate 42 is pushed by the filled gas, so that the sealing plate 42 slides out of the storage groove 41 with the magnetic block 43, and the magnetic block 43 is adsorbed with the metal height gauge 2 or the undercut depth gauge 3, thereby temporarily fixing the height gauge 2 or the undercut depth gauge 3, and then facilitating the measurement personnel to read.

[0047] When the pressing block 16 is released, the gas in the receiving groove 41 will flow back into the pressing block 16, and the second spring 44 will also reset the sealing plate 42, the protrusion 47 and the magnetic block 43 (when the sealing plate 42 slides toward the limit plate 46, the protrusion 47 is stuck in the groove 48). The second spring 44 cannot quickly reset the sealing plate 42, and will slowly remove the protrusion 47 on the sealing plate 42 from the groove 48, thereby delaying the reset and making it easier for the staff to confirm the value after the initial reading. The structure designed above can achieve the function of quickly fixing the height gauge 2 and the undercut depth gauge 3, without the need for the cumbersome and inefficient traditional knob style.

[0048] A detection method using the above steel structure detection equipment comprises the following steps: S1: Slide the slide bar 12 so that the slide bar 12 moves with the fixing plate 13 and the sandpaper 14 toward the welding position, and the positioning ring 191 on the surface of the slide bar 12 is temporarily fixed in the positioning groove 192 of the fixing frame 11, and the sandpaper 14 contacts the welding position of the steel structure, and rotate the slide bar 12 to rotate with the fixing plate 13 and the sandpaper 14, so that the fixing plate 13 and the sandpaper 14 are rotated 90 degrees and then contact the welding position of the steel structure; S2: When the slide bar moves, it brings the fixed plate 13 to continuously squeeze the liquid storage box 171, so that the cleaning agent pre-stored in the liquid storage box 171 enters the bottom plate 173 through the liquid outlet pipe 172, and then sprays out through the holes at the bottom of the bottom plate 173; S3: When the welding inspection ruler 1 is used for measurement, the gas in the pressing block 16 enters the receiving groove 41 and pushes the sealing plate 42 , so that the sealing plate 42 slides out of the receiving groove 41 with the magnetic block 43 .

[0049] Working principle: When using the welding inspection ruler 1 to detect the joint 22 of the steel structure, hold the pressing blocks 16 on both sides of the fixed frame 11 tightly, so as to facilitate the taking and using of the welding inspection ruler 1. When the welding inspection ruler 1 approaches the welding area, slide the sliding rod 12, so that the sliding rod 12 drives the fixing plate 13 and the sandpaper 14 to move towards the welding area, making the sandpaper 14 expose from the fixed frame 11, and let the positioning ring 191 on the surface of the sliding rod 12 snap into the positioning groove 192 of the fixed frame 11 for temporary fixation. At this time, the sliding rod 12, the fixing plate 13 and the sandpaper 14 will not reset under the action of the first spring 15, thus facilitating the sandpaper 14 to grind and remove impurities such as welding slag at the welding area of the steel structure. When there is too much welding slag at the welding area of the steel structure, rotate the sliding rod 12, and use the sliding rod 12 to drive the fixing plate 13 and the sandpaper 14 to rotate, so as to rotate the fixing plate 13 and the sandpaper 14 by 90°, and then change the vertical fixing plate 13 and sandpaper 14 into horizontal ones, so as to more efficiently remove impurities such as welding slag on the steel structure. By using the positioning ring 191 to enter the positioning groove 192, the fixing plate 13 is not easy to reset under the action of the first spring 15. At the same time, due to the friction between the positioning ring 191 and the positioning groove 192, the rotated sliding rod 12 will not be affected by the first spring 15 and reset.

[0050] When the sliding rod 12 drives the fixing plate 13 to move, both sides of the fixing plate 13 will continuously squeeze the liquid storage box 171, so that the pre-stored cleaning agent in the liquid storage box 171 enters the bottom plate 173 through the liquid outlet pipe 172 and sprays out through the holes at the bottom of the bottom plate 173. Thus, before the sandpaper 14 contacts the welding slag, the fixing plate 13 first squeezes and sprays the cleaning agent towards the welding slag, making impurities such as welding slag become soft, so as to cooperate with the subsequent removal of welding slag by the sandpaper 14. When the fixing plate 13 drives the sandpaper 14 to complete the work of removing welding slag, it will reset into the fixed frame 11. At this time, use the fixing plate 13 to squeeze the elastic ball 181, and squeeze the gas in the elastic ball 181 into the connecting pipe 182, and guide the gas to all around through the arc-shaped guide plate 183 in the connecting pipe 182. After the fixing plate 13 resets into the fixed frame 11, press the pressing block 16 again. The gas in the pressing block 16 will enter the air spraying pipe 24 through the communicating pipe 21 and blow towards the bottom surface of the sandpaper 14, using the gas in the pressing block 16 to assist in drying the bottom of the sandpaper 14.

[0051] When the pressing block 16 is pressed for the first time, since the pressing block 16 is made of a flexible material, it will move the connecting plate 31 and the connecting rod 32 toward the liquid storage box 171. The connecting rod 32 will move with the push plate 33 and several bosses 34 when moving, and the push plate 33 and the bosses 34 will be used to stir the detergent in the liquid storage box 171, thereby effectively preventing the detergent from settling after a long period of non-use, resulting in poor use effect. Since the pressing block 16 is made of an elastic material, when it is not squeezed, it will reset with the connecting plate 31, the connecting rod 32 and the push plate 33, thereby not affecting the subsequent squeezing of the liquid storage box 171 by the fixing plate 13.

[0052] After the welding slag removal work is completed, when the welding inspection ruler 1 is used for measurement, the connecting tube 21 and the air injection tube 24 are pulled out and separated, and the two connecting tubes 21 are respectively inserted into the corresponding butt joint tubes 45, so that the gas generated after pressing the pressing block 16 again will enter the storage groove 41 through the connecting tube 21 and the butt joint tube 45. When one end of the height gauge 2 and the undercut depth gauge 3 are in contact with the steel structure and measured, it is necessary to temporarily fix the depth gauge and the undercut depth gauge 3, so as to facilitate the measurement personnel to take accurate readings. At this time, the pressing block 16 is pressed, so that the gas in the pressing block 16 enters the storage groove 41, and the sealing plate 42 is pushed by the filled gas, so that the sealing plate 42 slides out of the storage groove 41 with the magnetic block 43, and the magnetic block 43 is adsorbed with the metal height gauge 2 or the undercut depth gauge 3, thereby temporarily fixing the height gauge 2 or the undercut depth gauge 3, and then facilitating the measurement personnel to take readings. When the pressing block 16 is released, the gas in the receiving groove 41 will flow back into the pressing block 16, and the second spring 44 will also bring the sealing plate 42, the protrusion 47 and the magnetic block 43 back to the original position. The second spring 44 cannot quickly bring the sealing plate 42 back to the original position, but will slowly bring the protrusion 47 on the sealing plate 42 out of the groove 48, thereby playing a role of delayed reset, which is convenient for the staff to confirm the value after the initial reading.
