Problems solved by technology

Existing levels need to be placed on the plane to be measured by hand, so that the reference plane of the level and the plane to be measured are completely fitted, requiring a certain amount of pressure from the hand. If it is a vertical plane, the operation will be more laborious, and it will also cause some Disturbance interference measurement results of
Or it is adsorbed on the surface of iron objects by magnets, but it cannot be adsorbed on smooth surfaces such as ceramic tiles, glass, plastics, etc., and it still needs to be fixed manually

Embodiment Construction

[0020] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". The following descriptions in the specification are preferred implementation modes for implementing the present invention, but the descriptions are for the purpose of illustrating the general principles of the present invention, and are not intended to limit the scope of the present invention. The scope of protection of the present invention should be defined by the appended claims.

[0021] The present invention will b...

Abstract

The invention discloses a level bar with suckers. The level bar with the suckers comprises a scale, a first spirit level and a reference plane, wherein the first spirit level is arranged on the upper side of the scale; the reference plane is arranged on the lower side of the scale; sucker devices are symmetrically arranged at two ends of the scale respectively; and the reference plane is used as a working reference surface of the first spirit level. The sucker devices are arranged at two ends of the scale of the level bar with the suckers, the level bar can be firmly fixed on the smooth surface of a measured object, interference is reduced, measuring precision is improved, when not used, the sucker devices are combined with the surface of the scale integrally, when in use, the sucker devices rotate to move downward, and the level bar with the suckers is attractive and practical.

Description

technical field [0001] The invention relates to the technical field of spirit levels, in particular to a level with a suction cup. Background technique [0002] The spirit level is mainly used to detect or measure the level and verticality, and can be divided into aluminum alloy square tube type, I-shaped type, die-cast type, plastic type, special-shaped and other specifications. Existing levels need to be placed on the plane to be measured by hand, so that the reference plane of the level and the plane to be measured are completely fitted, requiring a certain amount of pressure from the hand. If it is a vertical plane, the operation will be more laborious, and it will also cause some The disturbance interferes with the measurement results. Or it is adsorbed on the surface of the iron belt by a magnet, but it cannot be adsorbed on the surface of smooth objects such as ceramic tiles, glass, plastics, etc., and it still needs to be manually fixed. Contents of the invention ...
