Support of level instrument weight

Abstract

The invention discloses a supporting device of a heavy bob of a spirit level; the supporting device is arranged in a body of the spirit level; the heavy bob is supported in the body of the spirit level and is internally provided with a laser module; the supporting device comprises a fixing unit and a universal joint bearing, wherein, the fixing unit is arranged in the body of the spirit level, and the universal joint bearing is installed in the fixing unit; a shaft part is formed at the upper end of the heavy bob and is connected with the universal joint bearing, and the heavy bob is supported in the body of the spirit level in a swinging way by the universal joint bearing; therefore, the supporting device can achieve the effects such as structure simplification, easy assembly and disassembly as well as convenient manufacture, maintenance and correction, etc.

Description

technical field [0001] The invention relates to a support device for a level hammer, especially a support method for the level hammer, which can simplify the structure and facilitate disassembly and assembly, so as to facilitate the manufacture, maintenance and calibration of the weight support. device. Background technique [0002] Existing weight-type laser levels are all provided with a weight, in which at least one laser module (or laser transmitter) is installed, and the weight is supported inside the body by a supporting device, so that the weight can The front and rear and left and right swings, such as the Chinese Taiwan Patent No.: M288683, disclose relevant structures. [0003] The above-mentioned support device generally includes a main support ring, a secondary support ring, two first support shafts, two second support shafts and four bearings. The upper end of the weight is supported on the secondary support by two first support shafts and two bearings. ring, ...

AI Technical Summary

Problems solved by technology

[0004] At present, the support device for the weight of the spirit level includes at least one main support ring, one secondary support ring, two first support shafts, two second support shafts and four bearings. Inconvenient disassembly, especially the installation of bearings and support shafts, requires high precision, and a slight error will cause deviation and failure of the bearings and support shafts, resulting in abnormal operation

Obviously this kind of design is not conducive to manufacturing and maintenance, especially when the spirit level leaves the factory, it still needs to be returned to the original factory for calibration regularly, which will also cause inconvenience in operation
