Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of level calibration instruments, specifically relating to a multifunctional level calibration instrument for civil engineering. Background Technology
[0002] In the process of civil engineering construction, leveling is a crucial step in ensuring project quality, directly affecting the structural stability and subsequent functionality of buildings.
[0003] Currently, most level calibration tools on the market have limited functionality. In actual engineering measurements, in addition to levelness detection, it is often necessary to measure parameters such as distance and length. This requires additional tools such as measuring tapes and rangefinders, which not only increases construction costs but also causes inconvenience to on-site measurement work. Moreover, existing levels are also insufficient in terms of grip comfort and portability, and prolonged use can easily lead to hand fatigue for operators, reducing work efficiency.
[0004] Therefore, developing a multifunctional civil engineering level calibrator that integrates multiple functions, is easy to operate, and provides accurate measurements is of great practical significance. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by providing a multifunctional leveling instrument for civil engineering. The specific technical solution is as follows:
[0006] A multifunctional civil engineering level calibrator includes a level housing. A first cylindrical level, a second cylindrical level, and a third cylindrical level are mounted on the level housing for level detection. The first and second cylindrical levels are perpendicular. The included angles between the third and first cylindrical levels, and between the third and second cylindrical levels, are both 45 degrees. The first cylindrical level is located near the right-angled side of the level housing, and the second cylindrical level is located near the 45-degree side of the level housing. A measuring tape and a laser rangefinder are fixedly mounted on the level housing for length measurement. A mounting groove is formed on the right-angled side of the level housing, and a magnet is bonded and fixed within the mounting groove. An anti-slip grip is mounted on the side surface of the level housing.
[0007] Preferably, the anti-slip grip includes a handle fixed to the side surface of the level housing, a rubber sleeve installed in the middle of the handle, and a limiting silicone plate fixed to the side surface of the level housing, the limiting silicone plate being located inside the handle.
[0008] Preferably, the surface of the limiting silicone plate near the middle of the handle has a limiting groove for limiting the user's four fingers.
[0009] Preferably, the limiting silicone plate has through holes.
[0010] Preferably, the rubber sleeve has anti-slip rings integrally formed at equal intervals.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. The first, second, and third cylindrical levels mounted on the level housing allow users to easily attach the side of the level housing to the building surface as needed. This facilitates the observation of the building surface's levelness using the three levels together. A measuring tape and laser rangefinder are fixedly mounted on the level housing for length measurement, enhancing the level calibrator's functionality. Magnets are fixed in mounting slots on the right-angled sides of the level housing, allowing the level calibrator to adhere to the surface of iron objects using magnetic force, facilitating level measurement. An anti-slip handle mounted on the side surface of the level housing prevents users from easily detaching the level calibrator and makes it convenient to carry.
[0013] 2. The anti-slip grip is composed of a handle, a rubber sleeve, and a limiting silicone plate. The rubber sleeve is installed in the middle of the handle to increase the user's grip comfort. The limiting silicone plate, which is fixed to the side surface of the level housing, is located inside the handle. When the user holds the rubber sleeve, the four fingers are limited by the limiting grooves on the surface of the limiting silicone plate, thus achieving the anti-slip function. The through holes on the limiting silicone plate cause the limiting silicone plate to deform under external force. Attached Figure Description

[0018] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.
[0019] Please see Figure 1-3This embodiment provides the following technical solution: a multifunctional civil engineering level calibrator, including a level housing 1, on which a first cylindrical level 2, a second cylindrical level 3, and a third cylindrical level 4 for level detection are installed. The first cylindrical level 2 and the second cylindrical level 3 are perpendicular, and the included angle between the third cylindrical level 4 and the first cylindrical level 2, as well as the included angle between the third cylindrical level 4 and the second cylindrical level 3, are both 45 degrees. The first cylindrical level 2 is close to the right-angled side of the level housing 1, and the second cylindrical level 3 is close to the 45-degree side of the level housing 1. A measuring tape 5 for measuring length and a laser rangefinder 6 are fixedly installed on the level housing 1. A mounting groove 7 is opened on the right-angled side of the level housing 1, and a magnet 8 is glued and fixed in the mounting groove 7. An anti-slip grip is installed on the side surface of the level housing 1.
[0020] In this embodiment, the first cylindrical level 2, the second cylindrical level 3, and the third cylindrical level 4 installed on the level housing 1 allow the user to attach the side of the level housing 1 to the building surface as needed. This facilitates the observation of the building surface's levelness using the first cylindrical level 2, the second cylindrical level 3, and the third cylindrical level 4. The measuring tape 5 and the laser rangefinder 6 fixedly installed on the level housing 1 are used to measure length, enhancing the functionality of the level calibrator. The magnet 8 fixed in the mounting groove 7 on the right-angle side of the level housing 1 allows the level calibrator to be magnetically attracted to the surface of iron products when measuring them, facilitating level measurement. The anti-slip handle installed on the side surface of the level housing 1 allows the user to grip the level calibrator to prevent it from slipping off, making it easy for the user to carry the level calibrator.
[0021] Specifically, the anti-slip grip includes a handle 9 fixed to the side surface of the level housing 1, a rubber sleeve 10 installed in the middle of the handle 9, a limiting silicone plate 11 fixed to the side surface of the level housing 1, the limiting silicone plate 11 being located inside the handle 9, a limiting groove 12 for limiting the user's four fingers being opened on the surface of the limiting silicone plate 11 near the middle of the handle 9, and a through hole 13 being opened on the limiting silicone plate 11.
[0022] In this embodiment, an anti-slip grip component is provided, consisting of a handle 9, a rubber sleeve 10, and a limiting silicone plate 11. The rubber sleeve 10 is installed in the middle of the handle 9 to increase the user's grip comfort. The limiting silicone plate 11, which is fixed to the side surface of the level housing 1, is located inside the handle 9. When the user grips the outside of the rubber sleeve 10, the four fingers are limited by the limiting groove 12 provided on the surface of the limiting silicone plate 11, thus achieving the anti-slip function when the user grips the outside of the rubber sleeve 10. The through hole 13 provided on the limiting silicone plate 11 causes the limiting silicone plate 11 to be squeezed and deformed by external force.
[0023] Specifically, anti-slip rings are integrally formed at equal intervals on the rubber sleeve 10 to increase the surface roughness of the rubber sleeve 10.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
