Description

Technical Field

[0001] The utility model relates to the field of horizontal measurement tools, in particular to a curved spirit level. Background Art

[0002] In the field of decoration, horizontal measurement instruments are often used to measure the angular values of some decoration designs on horizontal planes, vertical planes or other angular values. The existing horizontal measurement instruments include electronic types and spirit level types. Among them, the existing spirit level type horizontal measurement instruments are mainly realized by installing a spirit level on a long straight ruler, such as the contents shown in the patent with the authorization announcement number CN208313289U and the application publication number CN116448057A. Most of the existing spirit levels directly install and combine a tubular spirit level, or set transparent plastics on both sides of the spirit level to protect the spirit level to a certain extent; while for the position of the bubble in the spirit level, only a rough control can be carried out. For example, when the bubble is controlled between two scale lines on the spirit level housing, it is considered to be horizontal. The reason is that it is difficult to accurately identify the position of the bubble in the spirit level. Therefore, a curved spirit level that can accurately read the position of the bubble is needed. Summary of the Invention

[0027] As Figures 1 - 5 shown, a curved spirit level bubble includes a spirit level bubble housing 1. The interior of the spirit level bubble housing 1 is hollow, and the hollow interior of the spirit level bubble housing 1 is used to hold a liquid for indicating the level, usually a green fluorescent liquid; the spirit level bubble further includes an outer shell 2; the outer shell 2 is integrally cylindrical with a hollow interior. On the one hand, it is used to place the spirit level bubble housing 1, and on the other hand, it is also used to reduce the overall mass of the outer shell 2 and reduce consumables; an opening 21 is provided on the outer arc surface of the outer shell 2, and the spirit level bubble housing 1 is fixedly arranged inside the outer shell 2; the upper and lower surfaces of the outer shell 2 are provided with convex lens structures 22 that protrude. The upper and lower surfaces of the outer shell 2 are made of a transparent material. Through the convex lens structures 22, the bubble located inside the spirit level bubble can be magnified, so as to more quickly and accurately control the position of the bubble. In this example, the spirit level bubble housing 1 and the outer shell 2 are integrally formed, and both are made of a transparent plastic material, such as transparent acrylic material, etc.

[0028] The edges of the upper and lower surfaces of the outer shell 2 are also provided with upwardly protruding skirts 23 for protecting the convex lenses on the upper and lower surfaces and reducing the wear and collision of the convex lenses by the outside world.

[0029] The inner contour of the skirt 23 on at least one of the upper and lower surfaces of the outer shell 2 is set as a regular polygon. In this example, a regular dodecagon is used, which is convenient for forming a snap connection with an external regular polygon tool, rotating the spirit level bubble, and adjusting the angle of the spirit level bubble in an external device, such as a spirit level, to better complete the level detection.

[0030] The outer side surface of the said housing 2 is also provided with a clamping projection 24 for calibrating the direction, and the clamping projection 24 is used for cooperating with the external structure for mounting a spirit level. The clamping projection 24 is a vertical strip-shaped projection, and the length direction of the strip-shaped projection is parallel to the central axis of the housing 2.

The inside of the spirit level housing 1 is a cylindrical cavity 12; the radius of the middle area of the cavity 12 is larger than the radius of its two ends, forming a cavity 12 structure that is thicker in the middle than at both ends, which is convenient for the water bubble to stay at a position close to the middle of the spirit level housing 1, and can more conveniently adjust the horizontal state.

[0032] During the implementation process, by providing a spirit level with a convex lens, it is convenient to observe the magnified water bubble through the convex lens, and the position of the water bubble can be read and adjusted more quickly and accurately; by providing the inside of the housing 2 to be hollow, the overall mass and consumables of the housing 2 are reduced; by providing a skirt 23 with a regular polygon on the inner side on the upper surface or the lower surface of the housing 2, it is convenient to rotate and adjust the housing 2 with the aid of a clamping and cooperating tool; by providing a clamping projection 24 on the outer side of the housing 2, it is convenient to adjust the housing 2 to a set angle and prevent it from rotating randomly when it is installed on an external structure, such as a spirit level.
