Problems solved by technology

[0002] Most of the liquid-connected leveling devices commonly used in construction projects are connected to the atmosphere. When in use, the liquid is easy to leak out, and sometimes it is necessary to fill the device with water, which brings a lot of inconvenience to the user.

Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] see figure 1 The two ends of the thin transparent tube (1) are connected with a relatively thick thick transparent tube (2), and the outer side of the thick transparent tube (2) has a scale (3) indicating the height of the liquid level. see figure 2 , the middle scale (6) of the scale (3) is marked with "0", and the colored liquid is not completely filled in the tube, so that the thick transparent tube (2) at both ends of the device leaves a vacuum part (4).

[0011] Design principle of the present invention is as follows.

[0012] There is a vacuum above the liquid surfaces at both ends of the device, so the absolute pressure at both liquid surfaces is 0. Due to the effect of gravity, the liquid surfaces at both ends of the device must be on the same horizontal plane when the device is at rest. When the device is manufactured, an appropriate amoun...

Abstract

The invention discloses a liquid communicated leveling instrument for a building. The leveling instrument consists of thick transparent pipes, a thin transparent pipe and a colored anti-freezing liquid. A device is only filled with a liquid without any air, and the device is not full of the liquid, so that the upper sides of liquid surfaces at two ends in the device are in the vacuum state. The leveling instrument is structurally characterized by comprising a thin transparent pipe, wherein the two ends of the thin transparent pipe are connected with relatively thick transparent pipes; and the outer sides of the thick transparent pipes are provided with graduations for indicating liquid surface heights. The pipe wall of the device is of a certain thickness, so that the inside of the device is in the vacuum state, and the device is prevented from being damaged and deformed under the condition of an external atmospheric pressure. The leveling instrument is suitable for scale height measurement in small-distance and small-height-difference construction, and has the characteristics of convenience for operating, simple structure and prevention of the liquid from leaking easily.

Description

technical field [0001] The invention relates to a device for measuring elevation in engineering construction. Background technique [0002] Most of the liquid-connected leveling devices commonly used in construction projects are connected to the atmosphere. When in use, the liquid is easy to leak out, and sometimes it is necessary to fill the device with water, which brings a lot of inconvenience to the user. Contents of the invention [0003] The present invention aims at the shortcomings of the above-mentioned level instrument, and provides a level instrument with simple structure, convenient use, and difficult leakage of liquid. [0004] The technical solution of the present invention is that the liquid-communicating level is a fully enclosed device, and there is only liquid in the device without air, and the liquid does not fill the tube, leaving a vacuum at the ends of the thick transparent tubes at both ends. Its structural feature is that it includes a thin transpa...
