DETAILED DESCRIPTION

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-6As shown, an embodiment of the utility model provides a measuring tool, including: a shell 1, a motor 2 is fixedly installed at one end of the shell 1, a top screw 3 is arranged in threaded cooperation, a base plate 4 is fixedly installed at the output end of the motor 2, a folding component 5 is rotationally damped and arranged on the base plate 4, a measuring instrument body 6 is fixedly installed at one end of the folding component 5, a cover plate 14 is slidingly arranged on the shell 1, four support components 7 are slidingly arranged on the shell 1, the support component 7 includes a support leg 8, a universal wheel 9 respectively fixedly installed at both ends of the support leg 8, and a rotating seat 10, a spring 11 is elastically connected between the support leg 8 and the shell 1, four fixed seats 12 corresponding to the four rotating seats 10 are fixedly installed on the lower surface of the shell 1, and two rotating wheels 15 are rotationally arranged on the upper side of the cover plate 14.

[0029] In this embodiment, specifically: a cavity 101 for accommodating the bottom plate 4 and the folding assembly 5 is opened in the outer shell 1, and a circular hole interconnected with the cavity 101 is opened on the lower surface of the outer shell 1. When the tool needs to be fixed to the ground, it is necessary to open a hole in the ground, and then insert the expansion bolt, and then the top of the expansion bolt passes through the circular hole, and then the nut on the expansion screw is rotated to fix the tool. The opening of the circular hole makes it easy to fix the tool.

[0030] In this embodiment, specifically: the output end of the motor 2 passes through the housing 1 and is fixedly connected to the bottom plate 4, and the folding assembly 5 includes a plurality of rotating bars 13 that are arranged in sequence to rotate and damp.

[0031] In the present embodiment, specifically: a conical groove 401 corresponding to the top screw 3 is provided on one side of the bottom plate 4, one end of the top screw 3 is a conical structure, and a gripper 1401 is provided on the outer shell 1 and the cover plate 14. When the motor 2 drives the bottom plate 4 to rotate, the bottom plate 4 is in a vertical state at this time. At this time, the top screw 3 needs to be rotated. After the top screw 3 is rotated, the bottom plate 4 is pressed tightly. When the bottom plate 4 is pressed, the bottom plate 4 is not easy to move, and the bottom plate 4 is not easy to move, so that the tool is more stable when used.

[0032] In this embodiment, specifically: two guide parts 102 are provided on both sides of the top of the shell 1, and two sliding parts 1402 corresponding to the two guide parts 102 are provided on the lower surface of the cover plate 14. The installation of the cover plate 14 can seal and protect the measuring instrument body 6, so that the measuring instrument body 6 is not easily damaged.

[0033] In this embodiment, specifically: the support leg 8 is an L-shaped structure, the top of one end of the support leg 8 is a columnar structure, and a disc protrusion 801 is provided on the upper surface of the support leg 8. The installation of the support leg 8 facilitates the movement of the universal wheel 9.

[0034] In this embodiment, specifically: the spring 11 is located between the disc protrusion 801 and the housing 1, the universal wheel 9 is located on the lower surface of one end of the support leg 8, and the installation of the universal wheel 9 allows the device to move after measuring one wall to measure the next wall.

[0035] In the present embodiment, specifically: a plurality of clamping protrusions 1001 are arranged on the rotating seat 10, a plurality of clamping recesses 1201 corresponding to the plurality of clamping protrusions 1001 are opened on the fixed seat 12, and the four fixed seats 12 are respectively arranged at a corner of the outer shell 1. When the rotating seat 10 slides toward the side close to the fixed seat 12, the clamping protrusion 1001 at this time contacts with the clamping recess 1201, and the rotating seat 10 is not easy to rotate at this time, so that the rotating seat 10 and the supporting leg 8 are more stable when used.

[0036] When the utility model is working: when the device needs to measure the flatness of the wall, the cover plate 14 is pulled first, and the cover plate 14 is opened. Then the tool is placed in front of the wall, and the motor 2 is turned on. The turning on of the motor 2 drives the bottom plate 4, the folding component 5, and the measuring instrument body 6 to rotate. Then, the folding component 5 is unfolded, the measuring instrument body 6 is opened, and the measuring instrument body 6 is opened to measure the distance between the wall and the measuring instrument body 6. At this time, the staff needs to record the measured value, and then unfold the folding component 5 to different positions, so that the measuring instrument body 6 can measure the distance between the measuring instrument body 6 and the wall. The cycle is repeated, and the flatness of the wall can be measured. Finally, the wall flatness information is obtained by calculation. It should be noted that this tool calculates the wall flatness information by taking points.

[0037] When the tool needs to increase the contact area with the ground, because the measuring instrument body 6 is raised and the folding assembly 5 is unfolded, the center of gravity of the tool is raised. At this time, the contact area between the tool and the ground needs to be increased. First, the support leg 8 is pulled downward. After the support leg 8 is pulled, the rotating seat 10 is separated from the fixed seat 12. At this time, the spring 11 is compressed and contracted. At this time, the support leg 8 is rotated. The rotation of the support leg 8 drives the universal wheel 9 to rotate. During the rotation of the universal wheel 9, the four universal wheels 9 are away from each other. When the four universal wheels 9 rotate After moving away, the contact area between the tool and the ground increases, and then the force pulling the supporting leg 8 is released, and the spring 11 pushes the supporting leg 8 to rise. When the supporting leg 8 is raised, the rotating seat 10 is in contact with the fixed seat 12, and the supporting assembly 7 no longer rotates because the universal wheel 9 increases the contact area between the tool and the ground, so that when the tool is used, it is not easy to tip over due to unstable center of gravity. When the tool is measured, it is necessary to push the cover 14 to close, and then pull the tool, then the rotating wheel 15 rotates, and the tool moves.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
