Description

A foldable measuring ruler

Technical Field

The utility model relates to the technical field of measuring rulers, in particular to a foldable measuring ruler.

Background Art

In urban and rural planning, the measuring ruler plays an important role as a basic measuring tool. It can be used to: measure the length and width of land and plots, which is very important for planning land use, determining land boundaries and drawing planning maps. It can also be used to mark length, distance and scale on planning drawings to help planners accurately present the planning layout, road network, building location and other information of cities or villages. In the process of urban and rural planning implementation, field surveys and investigations are required. The measuring ruler can be used to quickly measure specific geographical features such as buildings, land boundaries, and road widths, providing real-time data support for planning. The measuring ruler provides planners with necessary tool support, which helps to ensure the accuracy and feasibility of planning schemes. The existing measuring ruler can only measure simple lengths. When it is necessary to detect whether the ground is flat, ordinary measuring rulers cannot meet the measurement needs, and planners need to use other tools, which brings inconvenience to users.

Utility Model Content

In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

A foldable measuring ruler comprises a second ruler body, wherein a circular level is fixedly mounted on the surface of the second ruler body, an air bubble is arranged inside the circular level, and the air bubble can move freely inside the circular level.

Furthermore, the first scale body is rotatably mounted on one side of the second scale body, and the third scale body is rotatably connected to one side of the second scale body away from the first scale body. The third scale body can be placed in the first scale body.

Furthermore, a placement groove is provided in the first ruler body, and the third ruler body can be placed in the first ruler body through the placement groove.

Furthermore, a protractor is fixedly mounted on one side of the first scale body, and the protractor is arranged on a side of the first scale body close to the second scale body, and the protractor can measure the angle between the first scale body and the second scale body.

Furthermore, scale bars are arranged on the surfaces of the first scale body, the second scale body and the third scale body, and the scale bars are equidistantly engraved on the surfaces of the first scale body, the second scale body and the third scale body.

Furthermore, a hanging ring is provided on a side of the third ruler body away from the second ruler body, and both ends of the hanging ring are fixedly connected to the third ruler body.

Furthermore, an elastic strip is disposed on the outer cover of the second ruler body, and the elastic strip can cover the first ruler body, the second ruler body and the third ruler body together.

The beneficial effects of the utility model are as follows:

1. The utility model provides a circular level on the surface of the second ruler body and an air bubble in the circular level. When the measuring ruler is placed on the ground, if the air bubble is located at the center of the circular level, it means that the ground is level. If the air bubble is located at other positions of the circular level, it means that the ground is not flat. This solves the problem that the existing measuring ruler can only measure simple lengths. When it is necessary to detect whether the ground is flat, the ordinary measuring ruler cannot meet the measurement requirements and the planner needs to use other tools, which brings inconvenience to the user.

2. The utility model also provides a placement groove in the first ruler body, and the third ruler body can be placed in the first ruler body, so that it is more convenient for users to store when performing site measurement.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

The present application provides a foldable measuring ruler, which is mainly used to solve the problem that the existing measuring ruler can only measure simple length. When it is necessary to detect whether the ground is flat, the ordinary measuring ruler cannot meet the measurement requirements, and the planner needs to use other tools, which brings inconvenience to the user. The application also provides the following technical solutions, which will be described in detail in conjunction with Figures 1 and 2:

A foldable measuring ruler comprises a second ruler body 1, a circular level 2 is fixedly mounted on the surface of the second ruler body 1, an air bubble 3 is arranged inside the circular level 2, and the air bubble 3 can move freely in the circular level 2; a first ruler body 4 is rotatably mounted on one side of the second ruler body 1; a third ruler body 5 is rotatably connected to the side of the second ruler body 1 away from the first ruler body 4; the third ruler body 5 can be placed in the first ruler body 4; a placement groove 6 is provided in the first ruler body 4; the third ruler body 5 can be placed in the first ruler body 4 through the placement groove 6; a protractor 7 is fixedly mounted on one side of the first ruler body 4; the protractor 7 is arranged on the side of the first ruler body 4 close to the second ruler body 1; the protractor 7 can measure the angle between the first ruler body 4 and the second ruler body 1; The first scale body 4, the second scale body 1, and the third scale body 5 are provided with scale bars 8 on their surfaces, and the scale bars 8 are equidistantly engraved on the surfaces of the first scale body 4, the second scale body 1, and the third scale body 5. A hanging ring 9 is provided on the side of the third scale body 5 away from the second scale body 1, and both ends of the hanging ring 9 are fixedly connected to the third scale body 5. An elastic strip 10 is provided on the outer cover of the second scale body 1, and the elastic strip 10 can cover the first scale body 4, the second scale body 1, and the third scale body 5 together. In some embodiments, when measuring the length on the spot, the elastic strip 10 can be pulled out, and the third scale body 5 can be rotated out of the placement slot 6. When the first scale body 4 and the second scale body 1 are horizontal, the scale bars 8 engraved on the surfaces of the first scale body 4, the second scale body 1, and the third scale body 5 are The scale bar 8 is placed horizontally, and the measuring ruler can be unfolded. When measuring, the length can be measured by reading the scale bar 8 on the surface. When it is necessary to measure the angle of a corner, the first scale body 4 is rotated so that there is an angle between the first scale body 4 and the second scale body 1, and then the opposite surfaces of the first scale body 4 and the second scale body 1 are attached to the position to be measured. By observing the data on the protractor 7, the record can be completed.
