Description

a level ruler

technical field

The utility model relates to a measuring device, in particular to a level.

Background technique

The level is used to detect whether the surface of the object is level, but the existing level can only detect the plane. And for the object to be measured 13 as shown in Figure 1, there is a protruding part on the object to be measured 13, if we want to detect whether the planes on both sides of the protruding part are on the same horizontal plane, then using the existing spirit level is Unable to detect.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a level that can detect the levelness of objects with protruding parts on the surface.

The purpose of this utility model is achieved through the following technical solutions:

A level, comprising a level body, a bubble tube, a ruler, a fixed seat, an elastic patch, a pressing part, an elastic connecting piece, a magnet A, a magnet B, and a magnet C; the bubble tube is fixed on the level body; the level body There are fixed grooves at the bottom of both ends of the fixed groove, and a vertical chute is opened on one of the walls of the fixed groove. The seat is connected, the magnet C is set in the fixed seat; the elastic connecting piece runs through the bottom of the fixing groove, the top of the elastic connecting piece is connected with the pressing part, the bottom end of the elastic connecting piece is connected with the magnet B, and the top of the elastic patch is fixed in the fixing groove At the bottom of the bottom, the elastic patch is located between the scale and the elastic connecting piece, and the elastic patch is forced to approach the scale; magnet A and magnet B attract each other and press the elastic patch and the scale in the chute.

The working principle of the utility model is as follows:

The fixed seat is adsorbed on the object to be measured by the magnet C, and the protrusion on the object to be measured is located between the two fixed seats, and does not touch the level body, so that the parts on both sides of the protrusion of the object to be measured can be measured , to check whether they are on the same level.

In order to make the utility model have a wider application range, the utility model also provides the function of adjusting the distance between the fixing seat and the level body. Lift the pressing part upwards, the pressing part drives the magnet B to move upward through the elastic connecting piece, the magnet B is out of the adsorption range of the magnet A, and the elastic patch bounces away from the scale, at this time, the scale can slide up and down in the chute , so that the distance between the fixed seat and the level reaches a predetermined value, and then press down on the pressing part, magnet B enters the adsorption range of magnet A, magnet B and magnet A attract each other, and press the elastic patch and scale on the slide In the groove, the ruler cannot move again, thereby locking the distance between the fixed seat and the level body. Once done, you can start measuring.

The distance between the fixing seats at both ends of the level body and the level body can be guaranteed to be equal by the ruler.

Further, the elastic patch and the elastic connecting piece are aluminum thin sheets.

Aluminum is not magnetized and has good toughness. It avoids the problem that the iron sheet is easy to break after being bent many times, and the scale cannot slide freely because it is always attracted by the magnet after magnetization.

Further, the bottom of the chute is provided with an anti-slip rubber layer.

Further, a non-slip rubber layer is provided on the surface of the elastic patch opposite to the scale.

The non-slip rubber layer is provided to increase the friction between the scale and the chute or the elastic patch after the scale is compressed, preventing the scale from moving up and down during the measurement process, and increasing the reliability of the utility model when it works.

Further, a transparent plastic block is inlaid on the level body, marking lines are arranged horizontally in the transparent plastic block, and the transparent plastic block is adjacent to the chute.

To judge whether the distance between the two fixing seats and the level body is consistent, it is necessary to see the scale scale corresponding to the bottom surface of the level body, and since the bottom surface of the level bar is protruding relative to the scale, therefore, the corresponding scale on the bottom surface of the level body The scale marks are not easy to see. To solve this problem, set transparent plastic blocks. It is easier to observe the scale scale corresponding to the marking line through the transparent plastic block.

In summary, the advantages and beneficial effects of the present utility model are:

1. The utility model can detect the levelness of objects with protruding parts on the surface, and can challenge the adjustment of the distance between the fixing seat and the level body, and can measure objects with protruding parts of different heights;

2. The elastic patch and the elastic connecting piece are made of aluminum sheet, aluminum will not be magnetized, and has good toughness, avoiding that the iron sheet is easy to break after repeated bending, and the scale cannot slide freely due to being attracted by magnets after magnetization question;

3. The anti-slip rubber layer is provided, which can increase the friction between the scale and the chute or the elastic patch after the scale is pressed, preventing the scale from moving up and down during the measurement project, and increasing the reliability of the utility model when it works;

4. The transparent plastic block and the marking line are arranged to make it easier to observe the scale of the ruler, and it is beneficial to ensure that the distances between the two fixed seats and the level are equal.
