Description

Technical Field

[0001] The utility model relates to the field of construction tools, in particular to a spirit level for construction engineering construction. Background Art

[0002] A spirit level is a commonly used tool in building inspection and measurement, mainly used to measure the levelness and perpendicularity. By observing the positions of the horizontal bubble and the vertical bubble, it can judge the levelness and perpendicularity in the contacted direction. During operations such as decoration and item installation, we often need to use a spirit level to measure and correct the levelness or perpendicularity between multiple items. In short, a spirit level is a simple and practical tool that can help us quickly and accurately measure and correct the levelness or perpendicularity between multiple items. Whether in building inspection or daily decoration, it is one of the indispensable tools.

[0003] However, in the prior art, due to the relatively fixed length of the spirit level, its adaptability is low when used in different working environments and scenarios. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a spirit level for construction engineering construction.

[0005] To solve the above technical problem, the technical solution of the utility model: A spirit level for construction engineering construction includes an outer ruler. A chute is provided on the inner wall of the outer ruler. A slider is slidably connected inside the chute. One side of the slider is fixedly connected with an inner ruler. A threaded hole is provided at the upper end of the outer ruler. A bolt is arranged on the inner wall of the outer ruler. The lower end of the bolt is fixedly connected with a clamping ring. A clamping circle is sleeved outside the clamping ring. The lower end of the clamping circle is fixedly connected with a fixing plate. A through hole is provided on the front side of the outer ruler.

[0006] Preferably, a pressing block is fixedly connected to the left side of the inner ruler. A moving plate is fixedly connected to the left side of the pressing block. An end block is arranged outside the moving plate. A damping rod is arranged on the left side of the moving plate. A short rod is fixedly connected to the left edge position of the moving plate. A connecting ring is fixedly connected to the left side of the short rod. A spring is arranged on the left side of the connecting ring. The connecting ring is sleeved with a spring outside.

[0007] Preferably, the external thread of the bolt is adapted to the internal thread of the outer ruler.

[0008] Preferably, the fixing plate is movably connected with the bolt through the cooperation of the clamping circle and the clamping ring.

[0009] Through the above scheme, the following technical effects can be achieved: The outer ruler can be extended through components such as bolts, clamping rings, clamping circles, fixing plates, and sliders, thereby meeting different usage requirements and improving its adaptability.

[0010] Preferably, the connecting ring slides within the connecting circle through a spring.

[0011] Preferably, the number of the damping rods is two groups, and they are symmetrically arranged about the midline of the outer scale.

[0012] Through the above solution, the following technical effects can be achieved: components such as the damping rods, connecting circles, connecting rings, springs, and moving plates can buffer the two ends of the spirit level, thereby reducing the impact force received, and at the same time, the service life of the spirit level can also be extended.

[0013] Adopting the above technical solution, by rotating the bolt, under the action of the threaded hole inside the outer scale, the bolt drives the snap ring, snap ring, and fixing plate to move upward, releasing the limit on the inner scale. Pull the inner scale to one side, and the inner scale slides out from the outer scale. Rotate the bolt in the reverse direction, and the bolt pushes the fixing plate against the inner scale to fix it, that is, the extension of the outer scale is completed. During the sliding process of the inner scale, the slider slides inside the chute. With the cooperation of the slider and the chute, the stability of the inner scale during sliding can be increased. Components such as bolts, snap rings, snap rings, fixing plates, and sliders can extend the outer scale, thereby meeting different usage requirements and improving its adaptability at the same time.

[0014] Adopting the above technical solution, the preliminary buffering of the two ends of the spirit level can be realized through the provided damping rods, reducing the impact force received. When the damping rods contract due to impact, the moving plate slides inside the end block and makes the connecting ring compress the spring. The spring absorbs and converts the impact force, thereby further increasing the buffering effect. Components such as the damping rods, connecting circles, connecting rings, springs, and moving plates can buffer the two ends of the spirit level, thereby reducing the impact force received, and at the same time, the service life of the spirit level can also be extended.

[0024] Specifically, rotate the bolt 6. Under the action of the threaded hole 5 inside the outer ruler 1, the bolt 6 drives the snap ring 7, the retaining ring 8, and the fixed plate 9 to move upward, releasing the limit on the inner ruler 4. Pull the inner ruler 4 to one side, and the inner ruler 4 slides out from the outer ruler 1. Rotate the bolt 6 in the reverse direction, and the bolt 6 pushes the fixed plate 9 to closely adhere to the inner ruler 4 to fix it, that is, the extension of the outer ruler 1 is completed. During the sliding process of the inner ruler 4, the slide block 3 slides inside the slide groove 2. With the cooperation of the slide block 3 and the slide groove 2, the stability of the inner ruler 4 during sliding can be increased. The outer ruler 1 can be extended through components such as the bolt 6, the snap ring 7, the retaining ring 8, the fixed plate 9, and the slide block 3, thereby meeting different usage requirements and improving its adaptability.

[0025] Embodiment 2

[0026] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a spirit level for construction engineering. A pressing block 10 is fixedly connected to the left side of the inner ruler 4. A moving plate 16 is fixedly connected to the left side of the pressing block 10. An end block 11 is arranged outside the moving plate 16. A damping rod 17 is arranged on the left side of the moving plate 16. A short rod 15 is fixedly connected to the left edge position of the moving plate 16. A connecting ring 14 is fixedly connected to the left side of the short rod 15. A spring 13 is arranged on the left side of the connecting ring 14. The spring 13 is sleeved outside the connecting ring 14. The connecting ring 14 slides in the connecting ring 12 through the spring 13. The number of damping rods 17 is two groups, and they are symmetrically arranged about the midline of the outer ruler 1.

[0027] Specifically, the damping rods 17 provided can achieve preliminary buffering of both ends of the spirit level, reducing the impact force received. When the damping rods 17 contract due to impact, the moving plate 16 slides inside the end block 11 and the connecting ring 14 compresses the spring 13. The spring 13 absorbs and converts the impact force, thereby further increasing the buffering effect. Components such as the damping rods 17, connecting rings 12, connecting rings 14, springs 13, and moving plates 16 can buffer both ends of the spirit level, thereby reducing the impact force it receives and also extending the service life of the spirit level.

[0028] Working principle: When the spirit level for construction engineering is in use, first, place it on a stable surface and ensure that the outer ruler is in close contact with the object to be measured. Then, observe the positions of the spirit levels inside the inner ruler and the outer ruler, as well as the vertical spirit level. If they are in the central position, it indicates that the measured surface is horizontal or vertical. If the spirit level or the vertical spirit level deviates from the central position, it means that the measured surface is not horizontal or vertical. Then, the staff can make corresponding adjustments. When it is necessary to extend the length of the outer ruler 1, turn the bolt 6. Under the action of the threaded hole 5 inside the outer ruler 1, the bolt 6 drives the snap ring 7, the retaining ring 8, and the fixing plate 9 to move upward, releasing the limit on the inner ruler 4. Pull the inner ruler 4 to one side, and the inner ruler 4 slides out from the outer ruler 1. Reverse the rotation of the bolt 6, and the bolt 6 pushes the fixing plate 9 against the inner ruler 4 to fix it, that is, the extension of the outer ruler 1 is completed. During the sliding process of the inner ruler 4, the slider 3 slides inside the chute 2. With the cooperation of the slider 3 and the chute 2, the stability of the inner ruler 4 during sliding can be increased. The outer ruler 1 can be extended through components such as the bolt 6, the snap ring 7, the retaining ring 8, the fixing plate 9, and the slider 3, which can meet different usage requirements and improve its adaptability. When the two ends of the spirit level are impacted, the damping rod 17 provided can achieve preliminary buffering of the two ends of the spirit level, reducing the impact force received. When the damping rod 17 contracts due to the impact, the moving plate 16 slides inside the end block 11 and makes the connecting ring 14 compress the spring 13. The spring 13 absorbs and converts the impact force, further increasing the buffering effect. The two ends of the spirit level can be buffered through components such as the damping rod 17, the connecting ring 12, the connecting ring 14, the spring 13, and the moving plate 16, which can reduce the impact force received and extend the service life of the spirit level.
