[0002] A spirit level is a measuring tool mainly used for detecting or measuring horizontality and verticality. According to different materials, spirit levels can be divided into various types such as plastic, stainless steel, and aluminum alloy.

[0003] A spirit level includes a ruler body and a liquid level tube installed on the ruler body. Some spirit levels also have a magnet in the ruler body. The liquid level tube is sealed with a liquid with an indicator color and a spirit bubble above the liquid. There are also scale lines on the tube wall of the liquid level tube. When in use, people place the spirit level on the object to be detected, and then complete the inspection of the levelness by comparing the position of the spirit bubble with the scale lines.

[0004] In the prior art, some machine tools are provided with adjusting blocks at the bottom for adjusting the levelness of the tabletop. When people adjust the levelness of the machine tool, they place the spirit level on the machine tool. However, the shaking caused during the process of adjusting the adjusting blocks may cause the spirit level to fall over, and people need to pick up the spirit level again, which is rather inconvenient.

[0005] Therefore, a new solution is needed to solve this problem. Content of the Utility Model

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a spirit level.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: A spirit level, including a ruler body, grooves are respectively opened on two opposite side walls of the ruler body, support rods with one end rotatably connected to the side walls of the grooves are respectively arranged in the two grooves, a suction cup for adsorbing a machine tool is arranged at the movable end of the support rod, and an adjusting component for adjusting the distance between the support rod and the suction cup is arranged on the support rod.

[0008] The utility model is further arranged as: a threaded hole is opened at the movable end of the support rod, the adjusting component includes an adjusting rod rotatably connected in the threaded hole, and the suction cup is fixedly connected to one end of the adjusting rod.

[0009] The utility model is further arranged as: a dial rod perpendicular to the central axis of the adjusting rod passes through the end of the adjusting rod far from the suction cup, and an embedding groove for accommodating the dial rod is opened on the side wall of the groove.

[0010] The utility model is further arranged as: a protrusion is formed on the inner wall of the groove, and a limiting groove for being embedded by the protrusion is opened on the side wall of the support rod. When the limiting groove is embedded by the protrusion, the support rod is perpendicular to the ruler body.

[0011] The present utility model is further configured such that: the projection plane of the embedding groove is circular, and two ends of the lever are pasted with films for abutting against the peripheral wall of the embedding groove.

[0012] The present utility model is further configured such that: a digging groove is formed in the side wall of the support rod.

[0013] The present utility model is further configured such that: the ruler body is made of aluminum alloy.

[0014] To sum up, the present utility model has the following beneficial effects: when people use the spirit level to adjust the levelness of a machine tool, first place the end of the ruler body far from the liquid level tube flat on the machine tool, then turn out the support rod on the ruler body, and adsorb the suction cups at the movable ends of the support rod on the machine tool by adjusting the adjusting assembly. After both suction cups are adsorbed on the machine tool, people can complete the adjustment of the levelness of the machine tool by adjusting the adjusting block and referring to the level bubble in the liquid level tube on the spirit level. After people finish using the spirit level, the suction cups can be separated from the machine tool, and then the support rod is turned back into the groove. The formation of the groove enables the support rod to be stored in the groove when not in use, so that the setting of the support rod will not affect the portability of the ruler body. At the same time, the support rod is stored in the groove, and during the transportation and storage of the ruler body, the support rod is not likely to touch external objects, thus better protecting the support rod. The support rods are arranged on both sides of the ruler body, enabling the support rods to provide better support for the ruler body. The setting of the adjusting assembly enables people to adjust the distance between the support rod and the suction cup, so that the suction cup can better adapt to different surfaces of machine tools.

[0019] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0020] The spirit level, as shown in Figure 1 and Figure 2As shown, it includes a ruler body 1 and a liquid level tube installed on the ruler body 1, grooves 2 are opened on the two opposite side walls of the ruler body 1, and support rods 3 are provided in the two grooves 2, one end of which is rotatably connected to the side wall of the groove 2, and the movable end of the support rod 3 is provided with a suction cup 4 for adsorbing the desktop, and the support rod 3 is provided with an adjustment component for adjusting the distance between the support rod 3 and the suction cup 4. When people use the level ruler to adjust the level of the machine tool, first put the end of the ruler body 1 away from the liquid level tube flat on the machine tool, then turn the support rod 3 on the ruler body 1 out, and adsorb the suction cup 4 at the movable end of the support rod 3 on the machine tool by adjusting the adjustment component. When both suction cups 4 are adsorbed on the machine tool, people can then adjust the adjustment block and refer to the level bubble in the liquid level tube on the level ruler. To complete the adjustment of the horizontality of the machine tool, after people have used the level ruler, they can separate the suction cup 4 from the machine tool, and then turn the support rod 3 back into the groove 2. The opening of the groove 2 allows the support rod 3 to be stored in the groove 2 when not in use, so that the setting of the support rod 3 will not affect the portability of the ruler body 1. At the same time, the support rod 3 is stored in the groove 2. During the transportation and storage of the ruler body 1, the support rod 3 is not easy to touch external objects, thereby better protecting the support rod 3. The support rod 3 is set on both sides of the ruler body 1, so that the support rod 3 can provide better support for the ruler body 1. The setting of the adjustment component allows people to adjust the distance between the support rod 3 and the suction cup 4, so that the suction cup 4 can better adapt to different machine tool surfaces.

[0021] like Figure 2 and Figure 3As shown, a threaded hole 5 is provided at the movable end of the support rod 3. The adjusting assembly includes an adjusting rod 6 rotatably connected in the threaded hole 5. The suction cup 4 is fixedly connected to one end of the adjusting rod 6. During the process of people adsorbing the suction cup 4 on the machine tool, the distance between the suction cup 4 and the support rod 3 can be adjusted by rotating the adjusting rod 6, so that the suction cup 4 can be better adsorbed on the surface of the machine tool. The adjustment of the suction cup 4 by the adjusting rod 6 is achieved through threaded connection. When people rotate the adjusting rod 6, the feed amount of the adjusting rod 6 can be better controlled. One end of the adjusting rod 6 away from the suction cup 4 passes through a lever 7 perpendicular to the central axis of the adjusting rod 6. An embedding groove 8 for accommodating the lever 7 is provided on the side wall of the groove 2. When it is necessary to adjust the distance between the suction cup 4 and the support rod 3, the lever 7 on the adjusting rod 6 can be pinched with fingers, and then the adjusting rod 6 is rotated to complete the adjustment of the distance between the suction cup 4 and the support rod 3. The setting of the lever 7 provides people with a better force application point to rotate the adjusting rod 6. A protrusion 9 is formed on the inner wall of the groove 2, and a limiting groove 10 for the protrusion 9 to be embedded is provided on the side wall of the support rod 3. When the limiting groove 10 is embedded with the protrusion 9, the support rod 3 is perpendicular to the ruler body 1. When people need to use the suction cup 4 to fix the ruler body 1 on the machine tool, first rotate the support rod 3 out of the groove 2. After the protrusion 9 is embedded in the limiting groove 10, people can use the lever 7 to rotate the adjusting rod 6 to adjust the position of the suction cup 4. After people rotate the support rod 3 in place, the convex block will be embedded in the limiting groove 10 and cause the support rod 3 to vibrate. This vibration will generate a feedback to people's hands, so that people know that the support rod 3 has been rotated in place, and then subsequent operations can be started. In addition, when the support rod 3 has a tendency to rotate, the protrusion 9 embedded in the limiting groove 10 will abut against the inner wall of the limiting groove 10, so that the support rod 3 is not easy to rotate by itself, which preferably ensures the stability of the support rod 3.

[0022] As Figure 2As shown, the projection surface of the groove 8 is circular. Films 11 for abutting against the peripheral wall of the groove 8 are pasted at both ends of the lever 7. After people use the support rod 3, first adjust the distance between the suction cup 4 and the support rod 3 to the minimum. Then rotate the support rod 3 into the groove 2 and make the lever 7 embed in the groove 8. At this time, the films 11 at both ends of the lever 7 abut against the peripheral wall of the groove 8. The films 11 abutting against the peripheral wall of the groove 8 preferably increase the friction between the lever 7 and the inner wall of the groove 8, making it difficult for the lever 7 to spontaneously disengage from the groove 8, so that the support rod 3 is not easily disengaged from the groove 2, preferably ensuring the stability of the support rod 3 in the groove 2. A groove 12 is formed on the side wall of the support rod 3. When people need to use the support rod 3, they can insert their fingers into the groove 12. The setting of the groove 12 provides a better force application point for people to overcome the friction between the film 11 and the inner wall of the groove 8, so as to separate the lever 7 from the groove 8. The ruler body 1 is made of aluminum alloy. Aluminum alloy has the advantages of relatively light weight and high strength, making the ruler body 1 made of aluminum alloy have better strength while making the overall weight of the spirit level relatively light, making it more labor-saving for people to carry the spirit level.
