Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a universal leveler used for fixing or hanging objects on the top surface of a space such as a ceiling or a ceiling to measure the level of the objects. Background Art

[0002] A universal level, also known as a universal level, is a tool used to measure whether the surface of an object is parallel to the earth and whether it is horizontal. It is widely used in the fields of construction, civil engineering, aerospace, etc. In construction, a universal level can be used to determine whether walls, floors, roofs, etc. are horizontal; in the field of aerospace, a universal level can be used to test whether satellites and other space equipment are horizontal.

[0003] For example, the Chinese utility model patent "square universal level bubble" with patent publication number CN2844850Y includes a front shell and a rear shell, wherein the front shell is a hollow cube, the top surface of the inner wall of the front shell is a spherical measuring surface, the four side surfaces of the inner wall of the front shell are measuring surfaces composed of four arc surfaces whose normals are perpendicular to each other, and dividing lines are provided on the top surface and four side surfaces of the inner wall of the front shell, and the rear shell is fixed together with the front shell.

[0004] The universal level bubble in the above scheme can only measure the surface level of the ground or near-ground objects, and cannot measure whether the objects fixed or suspended on the top surface of the ceiling, ceiling, etc. are level. Utility Model Content

[0005] Aiming at the problem that the traditional universal level bubble cannot measure whether the objects fixed or hung on the top surface of the space such as the ceiling and the ceiling are level, the utility model provides a universal level for measuring the level of the objects installed on the top surface to solve the above problem.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: a universal level for measuring the level of an object installed on a top surface, comprising a shell, a level liquid chamber filled with a level liquid in the shell, a concave spherical surface on the inner wall of the bottom surface of the shell, a space between the level liquid and the spherical surface to form a level bubble, a graduation circle is arranged on the top surface of the shell, and the reference surface of the shell is installed on the object. When the level bubble is observed to be at the center position of the graduation circle, it can be determined that the object is level with the earth. In actual implementation, the universal level is installed on the surface of the top surface object, and the operator can observe the position of the level bubble in the universal level by looking up, so that the operator can adjust the position of the object so that the level bubble is at the center position of the graduation circle, thereby achieving the level of the object installed on the top surface with the earth.

[0007] A further preferred solution of the utility model is that the vertical projection of the highest point of the spherical surface coincides with the center point of the dividing circle. In actual implementation, when an operator looks up at the level bubble on an object, he often thinks that the installed object is level with the ground due to the deviation of the visual image. Therefore, the vertical projection of the highest point of the concave spherical surface of the inner wall of the bottom surface of the shell is used to coincide with the center point of the dividing circle as a further judgment of whether the object installed on the top surface is level with the ground.

[0008] A further preferred solution of the present invention is that the leveling liquid chamber is a polygonal column or a cylindrical body.

[0009] A further preferred solution of the utility model is: a water injection hole is provided on the bottom surface, and a small plug is provided in the water injection hole to close the water injection hole, so as to realize a sealed space environment after a certain amount of level liquid is injected into the level liquid chamber.

[0010] A further preferred scheme of the utility model is: the shell includes a level bubble shell, a large plug and a lens, the large plug is arranged at one end of the level bubble shell and closes the opening of the one end to form the bottom surface of the shell, the lens is arranged at the other end of the level bubble shell and closes the opening of the other end to form the top surface of the shell, the level bubble shell, the large plug and the lens together form the level liquid chamber.

[0011] A further preferred solution of the utility model is that the spherical surface is located on the inner surface of the large plug, and the dividing circle is located on the lens.

[0012] A further preferred solution of the present invention is that the vial shell and the lens are made of transparent materials.

[0013] Compared with the prior art, the utility model has the following advantages: an inwardly concave spherical surface is arranged on the inner wall of the bottom surface of the shell, and the top surface of the shell has a graduated circle. When in use, the reference surface of the shell is installed on an object, and a space is provided between the level liquid and the spherical surface to form a level bubble. By observing the position of the level bubble from the graduated circle, it can be judged whether the object installed on the top surface is level. This solves the technical problem in the prior art that the universal level bubble cannot be installed on the surface of the object on the top surface, and the horizontality of the object on the top surface cannot be measured by looking up. This produces a technical effect that the operator can judge that the object on the top surface is level with the earth when looking up and observing that the level bubble is at the center position of the graduated circle, thereby achieving fast and accurate horizontal installation of the object.

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0023] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0024] This embodiment mainly describes a universal level for a ceiling, as follows:

[0025] like Figures 1 to 6As shown, a universal level for measuring the level of an object mounted on a top surface comprises a shell 1, the shell 1 can be a polygonal column or a cylinder, preferably a cylinder, the shell 1 has a leveling liquid chamber 2 filled with a leveling liquid 3, the leveling liquid chamber 2 is a polygonal column or a cylinder, the bottom surface 12 of the shell 1 is parallel to the horizontal plane, the inner wall of the bottom surface 12 of the shell 1 has a concave spherical surface 121, the top surface 11 of the shell 1 has a dividing circle 111, and the vertical projection of the highest point of the spherical surface 121 coincides with the center point of the dividing circle 111 When the reference surface 4 on the shell 1 is attached to the object on the top surface of the space, a space is provided between the level liquid 3 and the spherical surface 121 to form a level bubble. For the convenience of observation, the top surface 11 or the interior of the graduation circle 111 is set to be made of transparent material. By observing the position of the level bubble from the graduation circle 111, it is judged whether the plane of the object installed on the top surface of the space is horizontal. When the level bubble is located at the center of the graduation circle 111, the plane of the object installed on the top surface of the space is level with the earth. Otherwise, it means that the plane of the object installed on the top surface of the space is not on the same level as the earth.

[0026] like Figure 3 and Figure 6 As shown, a water injection hole 122 is provided on the bottom surface 12, and the water injection hole 122 is used to inject the level liquid 3 into the level liquid chamber 2. A small plug 123 is provided in the water injection hole 122 to close the water injection hole 122. The arrangement of the water injection hole 122 and the small plug 123 makes it convenient to add the level liquid 3 into the level chamber 2, and can better control the amount of the added level liquid 3, so that the level liquid 3 can be controlled to fit with the bottom surface 12 of the shell 1, leaving only a little space for accommodating bubbles.

[0027] Specifically, the housing 1 includes a level bubble housing 13, a large plug 14 and a lens 15. The level bubble housing 13 has openings at both ends. Figure 6 As shown, the large plug 14 is arranged at one end of the level bubble shell 13 and closes the opening of one end to form the bottom surface 12 of the shell 1, and the lens 15 is arranged at the other end of the level bubble shell 13 and closes the opening of the other end to form the top surface 11 of the shell 1. The level bubble shell 13, the large plug 14 and the lens 15 together form the level liquid chamber 2, the concave spherical surface 121 is located on the inner surface of the large plug 14, and the dividing circle 111 is located on the lens 15. The level bubble shell 13 and the lens 15 are made of transparent material, which is convenient for viewing the position of the level bubble inside the level liquid chamber 2 and the overall aesthetics.

[0028] The reference surface 4 of the universal level can be fixed to the plane of the top object by pasting, or by screws, or other fixing methods. For example, elastic hooks 5 are provided on both sides of the level bubble shell 13, and the elastic hooks 5 can be used in conjunction with a fixing seat. The fixing seat can be pasted on the top surface, or fixed to the measured surface of the top object by screws. The fixing seat is provided with a hook groove that cooperates with the hook. The universal level is fixed to the top surface by the cooperation of the elastic hook 5 and the hook groove. The fixing method of the universal level in this scheme is not limited to the fixing methods listed above.

[0029] When in use, install the reference surface 4 of the universal level on the object on the top surface, and observe the position of the level bubble in the graduation circle 111. When the level bubble is located at the center of the graduation circle 111, the plane of the object installed on the top surface is level with the earth. Otherwise, it means that the plane of the object installed on the top surface is not on the same horizontal plane with the earth. The utility model is used to measure the level of equipment and devices installed or suspended on the top surface of the ceiling, ceiling and other spaces. During the installation and debugging of the equipment, the device is debugged so that the level bubble is centered in the graduation circle 111. Then the relevant working part of the device is level with the earth, and its parallelism falls within the design accuracy range of the device.

[0030] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0031] The universal level for measuring the level of objects installed on the top surface provided by the utility model is introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation mode of the utility model. The description of the above embodiments is only used to help understand the utility model and the core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified. These improvements and modifications also fall within the protection scope of the claims of the utility model.
