Description

Technical Field

[0001] The utility model relates to the technical field of levels, in particular to a building measurement level. Background Art

[0002] A digital level is a high-precision measuring instrument that is mainly used to measure ground elevation differences or height differences between objects. It uses a set of sophisticated optical systems and electronic sensors to automatically read and process the pattern of a special leveling rod on the aiming point to obtain height data. Compared with traditional optical or automatic levels, digital levels improve measurement speed and accuracy through digital processing, greatly reducing the possibility of human reading errors. It is widely used in civil engineering, construction, topographic mapping, infrastructure construction and other fields, especially in projects that require extremely high measurement accuracy. Digital levels not only improve work efficiency, but also record and store measurement data in real time for subsequent analysis and management. With its high efficiency and precision, digital levels have become one of the indispensable tools in modern measurement technology.

[0003] like Figure 1 As shown, the level in the prior art includes a digital level 1 and a measuring button 2 arranged on its shell, and the measuring button 2 is coupled to the digital level 1. As a digital level, although it still requires the operator to perform calibration and adjustment, the digital level is rotated on the tripod in the horizontal circumferential direction, and then after pressing the measuring button, the measuring switch electrically connected to the digital level will input a start signal, and the digital level will start to measure the level rod. However, since the bottom base of the digital level is fixed on the tripod, and the digital level is adjusted at an angle on the base, the specific rotation connection between the two is mainly achieved through the matching of the shaft hole. When the measuring button is pressed, the human hand will apply an eccentric force in the circumferential direction to the digital level. Even if the angle deflection is small, under the influence of the measuring distance of the digital level, its final measuring range will have a large deviation, resulting in the inability to accurately measure the level rod.

[0004] Therefore, a building measurement level is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a building measurement level.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A building measurement level comprises a tripod, a digital level detachably connected to the tripod, and a touch screen detachably connected to the tripod, wherein a controller in the touch screen is communicatively connected to a controller of the digital level.

[0008] Preferably, the controller in the touch screen is communicatively connected with the controller of the digital level via a coaxial cable.

[0009] Preferably, a back shell is fixedly connected to the back of the touch screen, and a clamping sleeve with a superior arc-shaped cross-section is fixedly connected to the back shell.

[0010] Preferably, a tightening component for reducing the distance between the two ends of the clamping sleeve is disposed on the outer side of the clamping sleeve.

[0011] Preferably, the tightening assembly includes arc piece 1 and arc piece 2 rotatably connected to the two ends of the clamping sleeve, and a positioning pin that can be embedded between arc piece 1 and arc piece 2. The arc piece 1 and arc piece 2 are staggered and distributed, and when arc piece 1 or arc piece 2 is at the maximum rotation angle, they are in surface contact with the end face of the clamping sleeve.

[0012] Preferably, both ends of the clamping sleeve are fixedly connected with a group of hinge seats, and the arc piece 1 and the arc piece 2 are rotatably connected between the two groups of hinge seats respectively.

[0013] Preferably, two groups of fixing sleeves with arc-shaped cross-sections are fixedly connected to the back shell, and the fixing sleeves are used to embed the positioning pins.

[0014] The utility model has the following beneficial effects:

[0015] The utility model design remotely controls the digital level by attaching a detachable touch screen to a tripod to achieve calibration and photographic measurement, avoiding deviation caused by direct contact with the digital level. It is connected through a coaxial cable and operates the touch screen instead of the level, reducing position errors caused by hand force and ensuring high precision and reliability of measurement data. This method greatly reduces errors in the measurement process and ensures the accuracy of the results. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] A building measurement level, such as Figure 2 As shown, it includes a tripod 3, a digital level 41 detachably connected to the tripod 3, and a touch screen 5 detachably connected to the tripod 3. The controller in the touch screen 5 is communicatively connected to the controller of the digital level 41. Specifically, the controller in the touch screen 5 is communicatively connected to the controller of the digital level 41 via a coaxial cable.

[0023] like Figure 3 and 4 As shown, the back of the touch screen 5 is fixedly connected to a back shell 6, and two groups of fixing sleeves 8 with a major arc-shaped cross-section are fixedly connected to the back shell 6, and the fixing sleeve 8 is used to embed the positioning pin 12. A clamping sleeve 7 with a major arc-shaped cross-section is fixedly connected to the back shell 6, and a tightening component for reducing the distance between the two ends of the clamping sleeve 7 is arranged on the outer side of the clamping sleeve 7. The tightening component includes an arc piece 10 and an arc piece 2 11 rotatably connected to the two ends of the clamping sleeve 7, and a positioning pin 12 that can be embedded between the arc piece 10 and the arc piece 2 11. The arc piece 10 and the arc piece 2 11 are staggered and distributed, and when the arc piece 10 or the arc piece 2 11 is at the maximum rotation angle and is arranged in surface contact with the end face of the clamping sleeve 7, both ends of the clamping sleeve 7 are fixedly connected to a group of hinge seats 9, and the arc piece 10 and the arc piece 2 11 are respectively rotatably connected between the two groups of hinge seats 9.

[0024] The two ends of arc piece 10 and arc piece 2 11 are fixedly connected with rotating shafts, and the hinge seat 9 is provided with holes that cooperate with the rotating shafts. In this way, the rotation of arc piece 10 or arc piece 2 11 and the hinge seat 9 can be achieved through the cooperation of the shaft and the hole.

[0025] The utility model only uses the digital level 41 to perform calibration and photographic measurement. The actual triggering and operation of the digital level 41 will not be carried out on the digital level 41, but through the touch screen 5 detachably connected to the tripod 3 to perform triggering, reading and other operations. The communication connection is made through a coaxial cable, so that when the digital level 41 is operated or triggered, the operator's hand force will not act on the digital level 41 adjusted in the horizontal direction, but will act on the touch screen 5 fixed on the tripod 3, so as to prevent the digital level 41 from receiving the horizontal force and deflecting on its base, so as to prevent the final picture taken by the digital level 41 from being unable to be aligned with the level ruler. In this way, there are few measurement errors in the measurement process of the level, thus ensuring the accuracy of the data finally obtained.

[0026] When the touch screen 5 needs to be installed on the tripod 3, it is only necessary to remove the positioning pin 12 from the fixing sleeve 8, and apply an outward force to the positioning pin 12 by human power to make the positioning pin 12 come into rigid contact with the fixing sleeve 8. Since the fixing sleeve 8, the clamping sleeve 7, the arc piece 10 and the arc piece 2 11 are all made of plastic, they have a certain elasticity and can be deformed to form an opening for the positioning pin 12 to leave.

[0027] Similarly, by pressing the openings at both ends of the clamping sleeve 7 against the legs of the tripod 3 and exerting force, the spacing between the openings at both ends of the clamping sleeve 7 can be increased to form an opening that can accommodate the legs of the tripod 3 to pass through, so that the clamping sleeve 7 is arranged on the outside of the legs of the tripod 3. If it is necessary to make the touch screen 5 more firmly set on the tripod 3 to avoid falling, it is only necessary to rotate the arc piece 10 and then the arc piece 2 11. When the arc piece 10 and the arc piece 2 11 are at the maximum rotation angle, the two are partially staggered, but the staggered position of the two cannot accommodate the positioning pin 12, and at this time, the two ends of the clamping sleeve 7 conflict with the arc piece 10 and the arc piece 2 11. 11 are unable to rotate, then the operator only needs to apply a force to the arc piece 1 10 and the arc piece 2 11 to make the two rotate, so that the arc piece 10 and the arc piece 2 11 respectively drive the two ends of the clamping sleeve 7 to move closer to each other, so that the degree of interlacing of the arc piece 10 and the arc piece 2 11 is further strengthened, and when the space formed between the two is sufficient to accommodate the positioning pin 12, the positioning pin 12 is inserted therein, and at this time, the two ends of the clamping sleeve 7 try to drive the arc piece 10 and the arc piece 2 11 to rotate, but the positioning pin 12 prevents the reverse deflection, so that the distance between the two ends of the clamping sleeve 7 is kept smaller than the normal state, so that it can clamp the legs of the tripod 3 to avoid the touch screen 5 from falling off.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
