Description

Technical Field

[0001] This utility model relates to the technical field of engineering acceptance level rulers, and in particular to a telescopic level ruler for engineering acceptance. Background Technology

[0002] In the current construction environment of engineering projects, after the construction party completes the construction, installation, and commissioning stages of the project, the acceptance unit's acceptance personnel will conduct acceptance of various parameters to confirm whether the project meets the design requirements, contractual agreements, and relevant national standards. Generally, the most common tool used in the acceptance process is a spirit level.

[0003] However, existing spirit levels used for engineering acceptance have certain shortcomings in practical applications. Typically, existing spirit levels can only be used to check the levelness of the acceptance surface and measure the length of the acceptance surface that does not exceed the length of the spirit level. For acceptance measurements of longer acceptance surfaces, there are significant limitations, which restricts the applicability of the current spirit level. Therefore, there is an urgent need to address this issue. Utility Model Content

[0004] In view of this, the present invention provides a telescopic level for engineering acceptance. The main technical problem to be solved is that the existing level is convenient for testing the levelness of the acceptance plane and for measuring the length of the acceptance plane that does not exceed the length of the current level. However, it has a great limitation when measuring the acceptance plane with a larger length.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a telescopic level for engineering acceptance, comprising a first level body, a second level body, a protrusion, and a sliding rod. The first level body and the second level body are rotatably connected. Two sliding rods are provided, and the two sliding rods are respectively slidably connected inside the first level body and the second level body. The protrusion is fixedly connected to the outer wall of the sliding rod.

[0006] The first and second rulers each have a second storage groove inside. The sliding rod is slidably connected inside the second storage groove. The first ruler has a second hexagonal nut movably connected inside. The second hexagonal nut fits against the outer wall of the sliding rod. The first and second rulers each have a first knob bolt threaded inside. The sliding rod has a first square groove inside. The first knob bolt is movably connected inside the first square groove. The first knob bolt and the second hexagonal nut are threaded together.

[0007] The first ruler body has a first storage groove inside, and a sliding plate is slidably connected inside the first storage groove. The sliding plate has a second square groove inside, and the second ruler body has a mating groove inside. The sliding plate is movably connected inside the mating groove. The second ruler body has a second knob-type bolt threaded inside, and a first hexagonal nut movably connected inside the second ruler body. The first hexagonal nut fits against the outer wall of the sliding plate. The second knob-type bolt is movably connected inside the second square groove, and the second knob-type bolt and the first hexagonal nut are threaded together.

[0008] By adopting the above technical solution, the first and second rulers are rotatably connected. When the level needs to be unfolded, the second ruler is rotated and unfolded. After being fully unfolded, the sliding plate in the first storage groove of the first ruler can be slid out into the mating groove of the second ruler. When the sliding plate is fully in contact with the bottom of the mating groove, the first hexagonal nut can be threaded up on the second knob bolt by rotating it until the sliding plate in the mating groove is locked, thus completing the locking and fixing of the first and second rulers after unfolding. The sliding rod of the first and second rulers located in the second storage groove facilitates the adjustment of the protrusion by stretching and pushing it out. When the protrusion is adjusted to a suitable length, the second knob bolt can be rotated to thread up the second hexagonal nut on the first knob bolt until the sliding rod in the second storage groove is fitted into the second storage groove and locked, thus completing the extension and retraction adjustment of the protrusion. The current structural design allows the level of the same length to have a larger acceptance length calculation range by using a folding ruler and an extendable ruler design, thereby improving the acceptance applicability of the equipment.

[0009] As a further description of the above technical solution: a push rod is fixedly connected to one side of the upper end face of the sliding plate, a sliding groove is opened inside the first ruler body, the sliding groove corresponds to the first storage groove, and the push rod is movably connected inside the sliding groove.

[0010] By adopting the above technical solution and the above structural design, it is convenient to push the push rod to slide in the groove, thereby driving the sliding plate integrated with the push rod to slide and adjust its position in the first storage groove.

[0011] As a further description of the above technical solution: a second magnetic block is installed on the inner wall of the first storage slot away from the second ruler, and a first magnetic block is installed on the outer wall of the sliding plate away from the second ruler, and the first magnetic block and the second magnetic block are magnetically connected.

[0012] By adopting the above technical solution and the above structural design, the sliding plate in the first storage slot can be firmly attracted to the storage slot in the storage state through the magnetic attraction between the first magnetic block on the sliding plate and the second magnetic block in the first storage slot. This can prevent the sliding plate from sliding out of the first storage slot when the level is folded.

[0013] As a further description of the above technical solution: a third bubble level is installed inside the second ruler body, and a second bubble level is installed inside the first ruler body.

[0014] By adopting the above technical solution, the third bubble level installed on the second ruler can roughly confirm the tilt of the platform when the level is upright, and the second bubble level installed on the first ruler can determine whether the current plane is level by whether the bubble is centered.

[0015] As a further description of the above technical solution: a first bubble level is fixedly connected inside the first ruler body and the second ruler body, and a groove is opened inside the first ruler body and the first bubble level is installed inside the groove.

[0016] By adopting the above technical solution, the first bubble level can be used to determine whether the levelness of the current acceptance plane meets the requirements by observing whether the bubble in the first bubble level is centered when the level ruler is attached to the plane to be inspected.

[0017] As a further description of the above technical solution: a positioning block is fixedly connected to the outer wall side of the second ruler body near the first ruler body, and the positioning block is in contact with the outer wall of the first ruler body.

[0018] By adopting the above technical solution, the positioning block set on the second ruler can be used to hold the second ruler in place when the horizontal ruler changes from the folded state to the unfolded state, so that the second ruler and the first ruler are horizontally aligned in the unfolded state, and the sliding plate in the first storage slot can be aligned with the mating slot on the second ruler.

[0019] As a further description of the above technical solution: the outer walls of both the first and second rulers are provided with scales, and the scales are also provided on the outer walls of the protrusions and the sliding rod.

[0020] By adopting the above technical solution, the scales set on the first and second rulers can be used to detect the length of the inspection surface in both the folded and unfolded states. The scales set in the sliding rod and the protrusion can be used to quickly determine the length of the current inspection surface by adding the scales on the extended sliding rod and the protrusion to the scales on the first and second rulers.

[0021] By employing the above technical solution, the telescopic level for engineering acceptance of this utility model has at least the following beneficial effects:

[0022] Compared with existing technologies, this telescopic level for engineering acceptance, by designing the level body to be folded by rotating the first and second sections and adding a telescopic adjustment mechanism, gives the current equipment a larger acceptance length range than level bodies of the same length specifications. Moreover, the telescopic length can be adjusted according to different construction specifications, greatly improving the applicability of the current equipment for acceptance.

[0033] Reference Figure 1-8This utility model provides a telescopic level for engineering acceptance: it includes a first level body 1, a second level body 2, a protrusion 3, and a sliding rod 4. The first level body 1 and the second level body 2 are rotatably connected. Two sliding rods 4 are provided, each slidably connected inside the first level body 1 and the second level body 2 respectively. The protrusion 3 is fixedly connected to the outer wall of the sliding rod 4. A second storage groove 20 is provided inside both the first level body 1 and the second level body 2, and the sliding rod 4 is slidably connected inside the second storage groove 20. A second hexagonal nut 23 is movably connected inside the first level body 1, and the second hexagonal nut 23 fits against the outer wall of the sliding rod 4. A first knob-type bolt 6 is threadedly connected inside both the first level body 1 and the second level body 2. A first square groove 5 is provided inside the sliding rod 4. The first knob-type bolt 6 is movably connected inside the first square groove 5. The first knob-type bolt 6 and the second hexagonal nut 23 are threadedly connected. The first ruler body 1 has a first storage groove 17 inside. A sliding plate 12 is slidably connected inside the first storage groove 17. A second square groove 16 is opened inside the sliding plate 12. The second ruler body 2 has a mating groove 13 inside. The sliding plate 12 is movably connected inside the mating groove 13. A second knob-type bolt 14 is threadedly connected inside the second ruler body 2. A first hexagonal nut 19 is movably connected inside the second ruler body 2. The first hexagonal nut 19 fits against the outer wall of the sliding plate 12. The second knob-type bolt 14 is movably connected inside the second square groove 16. The second knob-type bolt 14 and the first hexagonal nut 19 are threadedly connected. The first ruler body 1 and the second ruler body 2 are rotatably connected. When the level needs to be unfolded for use, the second ruler body 2 is rotated and unfolded. After being fully unfolded, the sliding plate 12 in the first storage groove 17 of the first ruler body 1 can be slid out into the mating groove 13 of the second ruler body 2. When the sliding plate 12 is completely in contact with the bottom of the mating groove 13, the first hexagonal nut 19 can be threaded onto the second knob bolt 14 by rotating it until the sliding plate 12 in the mating groove 13 is locked, thus completing the locking and fixing of the first ruler body 1 and the second ruler body 2 after unfolding. The sliding rod 4, located within the second storage groove 20, facilitates the adjustment of the protrusion 3 by stretching and pushing it out. After the protrusion 3 is adjusted to the appropriate length, the second knob bolt 14 can be rotated to cause the second hexagonal nut 23 to rise on the thread of the first knob bolt 6 until the sliding rod 4 in the second storage groove 20 is engaged with the second storage groove 20 and locked, thus completing the extension and retraction adjustment of the protrusion 3. The current structural design allows the level ruler of the same length to have a larger acceptance length measurement range by using a folding ruler body and an extendable ruler body design, thereby improving the acceptance applicability of the equipment.

[0034] A push rod 9 is fixedly connected to one side of the upper end face of the sliding plate 12. A sliding groove 10 is formed inside the first ruler body 1, which corresponds to the first storage groove 17. The push rod 9 is movably connected inside the sliding groove 10. The above structural design facilitates the sliding adjustment of the sliding plate 12, which is integrated with the push rod 9, within the first storage groove 17 by pushing the push rod 9 to slide within the sliding groove 10.

[0035] A second magnetic block 21 is installed on the inner wall of the first storage slot 17 away from the second ruler body 2, and a first magnetic block 18 is installed on the outer wall of the sliding plate 12 away from the second ruler body 2. The first magnetic block 18 and the second magnetic block 21 are magnetically connected. This structural design allows the sliding plate 12 in the first storage slot 17 to be firmly attached to the storage slot in the folded state through the magnetic attraction between the first magnetic block 18 on the sliding plate 12 and the second magnetic block 21 in the first storage slot 17. This prevents the sliding plate 12 from sliding out of the first storage slot 17 when the level is folded.

[0036] The second ruler 2 has a third bubble level 15 installed inside, and the first ruler 1 has a second bubble level 8 installed inside. The third bubble level 15 installed on the second ruler 2 can roughly determine the tilt of the platform when the level is upright, and the second bubble level 8 installed on the first ruler 1 can determine whether the current plane is level by whether the bubble is centered.

[0037] Both the first ruler body 1 and the second ruler body 2 are fixedly connected to a first bubble level 7. The first ruler body 1 and the second ruler body 2 have grooves 24 inside, and the first bubble level 7 is installed inside the grooves 24. The first bubble level 7 allows the level of the surface to be inspected to be determined by observing whether the bubble inside the first bubble level 7 is centered when the level is in contact with the surface to be inspected.

[0038] A positioning block 11 is fixedly connected to the outer wall of the second ruler 2 near the first ruler 1, and the positioning block 11 fits against the outer wall of the first ruler 1. The positioning block 11 on the second ruler 2 can hold the second ruler 2 in place when the horizontal ruler changes from a folded state to an unfolded state, ensuring that the second ruler 2 and the first ruler 1 are horizontally aligned in the unfolded state, so that the sliding plate 12 in the first storage groove 17 can be aligned with the mating groove 13 on the second ruler 2.

[0039] The outer walls of both the first ruler body 1 and the second ruler body 2 are provided with scales 22. Scales 22 are also provided on the outer walls of the protrusion 3 and the sliding rod 4. The scales 22 on the first ruler body 1 and the second ruler body 2 can be used to detect the length of the inspection surface in both the folded and unfolded states. The scales 22 inside the sliding rod 4 and the protrusion 3 can be used to quickly determine the length of the current inspection surface by adding the scales 22 on the extended sliding rod 4 and the protrusion 3 to the scales 22 on the first ruler body 1 and the second ruler body 2.

[0040] Working principle: In actual use, when it is necessary to accept the project that is about to be delivered, the acceptance personnel can determine whether the current acceptance plane is level by placing the side of the current equipment on the plane to be inspected and observing whether the bubbles on the first bubble level 7 and the second bubble level 8 are centered and whether the bubble on the third bubble level 15 is at the top.

[0041] When it is necessary to measure whether the length and width of the acceptance plane meet the construction requirements, if the distance of the acceptance plane is greater than the distance of the horizontal ruler without extension and retraction adjustment in the folded state, but less than the distance of the horizontal ruler without extension and retraction adjustment in the unfolded state, at this time, while keeping the horizontal ruler in the folded state, the first knob bolt 6 can be loosened by rotating it so that the second hexagonal nut 23 no longer locks the sliding rod 4, so that the sliding rod 4 can slide in the second storage groove 20. Then adjust it until the edge of the protrusion 3 is aligned with the edge of the acceptance plane. By rotating and tightening the first knob bolt 6, the second hexagonal nut 23 locks the sliding rod 4 again, so that the protrusion 3 is fixed at the current acceptance length. At this time, by reading the scale 22 on the protrusion 3, adding the scale 22 on the exposed sliding rod 4, and adding the scale 22 on the first ruler body 1, the length and width values ​​of the current acceptance plane can be obtained. Under the premise of ensuring the current measurement length, the length of each point in the longitudinal direction of the acceptance plane can be calculated to ensure the accuracy of the acceptance.

[0042] When the distance to the inspection surface is greater than the distance at which the level ruler does not extend or retract in its unfolded state, the inspector can rotate and unfold the second ruler body 2. When the second ruler body 2 is rotated to be level with the first ruler body 1, the inspector then pushes the push rod 9 to move the sliding plate 12 in the first storage groove 17 into the mating groove 13 of the second ruler body 2. When the sliding plate 12 is pushed deep enough into the mating groove 13, the inspector tightens the second knob bolt 14 by rotating it, causing the thread of the first hexagonal nut 19 in the second ruler body 2 to rise, locking the sliding plate 12 in the mating groove 13, thus completing the unfolding operation of the level ruler. Then, the first knob bolts on the first ruler body 1 and the second ruler body 2 are loosened by rotating them. 6. This causes the second hexagonal nut 23 to no longer lock the sliding rod 4, allowing the sliding rods 4 at both ends to slide in the second storage groove 20. Then, adjust the edges of the protrusions 3 at both ends to align with the edges of the acceptance plane at both ends. By rotating and tightening the first knob bolt 6, the second hexagonal nut 23 locks the sliding rod 4 again, fixing the protrusions 3 at the current acceptance length. At this point, by reading the scale 22 on the two protrusions 3, adding the scale 22 on the exposed sliding rods 4 at both ends, and adding the scale 22 on the first ruler 1 and the second ruler 2, the length and width values ​​of the current acceptance plane can be obtained. This allows for the calculation of the length at various points in the longitudinal direction of the acceptance plane while ensuring the current measured length, thus guaranteeing the accuracy of the acceptance.
