Description

Technical Field

[0001] This utility model belongs to the technical field of level measuring instruments, and in particular relates to a level measuring instrument for construction. Background Technology

[0002] Construction surveying instruments are various instruments used for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry during the planning, design, construction, and operation management phases of engineering construction. These instruments play a crucial role in these phases, measuring parameters such as elevation differences, distances, and angles between two points on the ground to ensure the accuracy and efficiency of construction. Through precise design and high-tech applications, they provide accurate measurement results, helping construction personnel determine horizontal positions and elevation differences, thereby ensuring the stability and safety of buildings.

[0003] The following problems exist with the level measuring instruments currently on the market during use:

[0004] 1. In practical applications, traditional construction level measuring instruments mostly rely on the tripod's bottom end to directly contact the ground for observation and recording. However, the bottom end of the tripod is often spiked, which does not provide a strong fixation to the ground, resulting in a certain degree of instability in the instrument's observation data.

[0005] 2. Most construction level measuring instruments are often directly fixed to the tripod using the bolts that come with it. However, this can easily lead to stiffness or jamming of parts, making installation difficult and negatively impacting construction efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide a level measuring instrument for construction, so as to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A construction level measuring instrument includes a measuring instrument body and a support frame. A telescopic rod is installed in the interior of the support frame through a hole. A limiting ring is installed on the surface of the telescopic rod. A movable rod is provided inside the telescopic rod. A first ground nail is fixedly connected to the bottom of the movable rod. A cross plate is threadedly connected to the surface of the movable rod. A second ground nail is inserted into a hole on the surface of the cross plate.

[0008] Preferably, a fixing plate is installed on the top of the support frame, a sliding groove is formed on the top of the fixing plate, and a slider is fixedly connected to the bottom of the measuring instrument body, the slider being slidably connected to the sliding groove.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a construction level measuring instrument.

[0028] like Figure 1-4 As shown, this utility model discloses a construction level measuring instrument, including a measuring instrument body 1 and a support frame 2. A telescopic rod 4 is installed in the interior of the support frame 2. A limiting ring 5 is installed on the surface of the telescopic rod 4. A movable rod 6 is provided inside the telescopic rod 4. A first ground nail 8 is fixedly connected to the bottom of the movable rod 6. The length of the movable rod 6 is fixed by the limiting ring 5, which facilitates the first ground nail 8 to penetrate into the ground. A cross plate 7 is connected to the surface of the movable rod 6 by threads. A second ground nail 9 is inserted into the surface of the cross plate 7. Through the cross plate 7 and the second ground nail 9, the overall structure can be more firmly fixed on the ground.

[0029] A fixed plate 14 is installed on the top of the support frame 2. A sliding groove 13 is opened on the top of the fixed plate 14. A slider 12 is fixedly connected to the bottom of the measuring instrument body 1. The slider 12 is slidably connected to the sliding groove 13. The mutual sliding cooperation between the sliding groove 13 and the slider 12 makes the installation of the measuring instrument body 1 more convenient to a certain extent.

[0030] A nut 11 is fixedly connected to the outer surface of the fixed plate 14, and a screw 10 is threadedly connected to the inner wall of the nut 11. A handle 15 is installed at one end of the screw 10. By rotating the handle 15, the screw is rotated, so that the slider 12 can be fixed.

[0031] There are four second ground anchors 9, which are evenly distributed. The four evenly distributed second ground anchors 9 make the overall structure more stable on the ground.

[0032] The surface of the support frame 2 is connected to the support rods 3 by bolts. There are three support rods 3, which are evenly distributed. The support frame 2 is stably supported by the three support rods 3.

[0033] Foot pads 16 are installed at the bottom of the support rod 3. There are three foot pads 16, which are evenly distributed. The installation of foot pads 16 increases the friction between the support rod 3 and the ground to a certain extent, thereby increasing stability.

[0034] The working principle of this construction level measuring instrument is as follows: When using this instrument, the operator first needs to take the device to the designated location. A foot pad 16 is installed at the bottom of the support rod 3. The support rod 3 is then opened and placed vertically on the ground, allowing the foot pad 16 to have a large contact area with the ground. A telescopic rod 4 is located at the bottom of the support frame 2. A limiting ring 5 is installed on the surface of the telescopic rod 4, and a movable rod 6 is located inside the telescopic rod 4. Rotating the limiting ring 5 extends the movable rod 6. A first ground nail 8 is fixedly connected to the bottom of the movable rod 6, and a cross plate 7 is threaded onto the surface of the movable rod 6. A hole is made inside the cross plate 7 to insert a second ground nail 9. Using the first ground nail 8 and the second ground nail 9, the device is driven into the ground, thus improving the overall stability of the device to a certain extent. The top of the support frame 2 is provided with a fixed plate 14, and the top of the fixed plate 14 is provided with a sliding groove 13. The bottom of the measuring instrument body 1 is fixedly connected to a slider 12. The slider 12 and the sliding groove 13 cooperate with each other through a sliding connection, making the installation of the measuring instrument body 1 smoother and more convenient. The outer surface of the fixed plate 14 is fixedly connected to a nut 11, and the inner wall of the nut 11 is threadedly connected to a screw 10. One end of the screw 10 is equipped with a handle 15. When the measuring instrument body 1 is moved to a suitable position by sliding, the screw 10 is rotated by turning the handle 15, so that the slider 12 is fixed in the sliding groove 13, thereby fixing the measuring instrument body 1. At this time, the operator can adjust the parameter settings of the measuring instrument body 1 according to the actual situation for observation.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
