Detailed Description
The quality inspection of the house is an important link in the house construction process, and the squaring measurement of the floor and the wall of a room is one of the main measurement contents of the house quality inspection. However, at present, no instrument specially used for detecting the squareness of the floor or the wall of a room is available in the market, and detection personnel basically judge the squareness of the room by manually measuring the length, the width and the diagonal dimension of the floor or the wall of the room by using a measuring tape.

The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The second measuring stick 200 is rotatably connected to the central shaft 800, cavities are formed in the first measuring stick 100 and the second measuring stick 200, and a first motor 300, a first transmission device driven by the first motor 300, a first telescopic rod 120 driven by the first transmission device, a second motor 400, a second transmission device driven by the second motor 400, a second telescopic rod 140 driven by the second transmission device, and a control system are arranged in each of the two cavities.
One end of each of the first measuring rod 100 and the second measuring rod 200 is provided with a first extending opening matched with the first telescopic rod 120, the other end of each of the first measuring rod 100 and the second measuring rod 200 is provided with a second extending opening matched with the second telescopic rod 140, the first telescopic rod 120 and the second telescopic rod 140 are parallel to each other and are respectively connected in the cavity in a sliding mode, the control system comprises a control button 600 for starting or closing the first motor 300 and the second motor 400, the control button 600 is arranged on the outer wall of each of the first measuring rod 100 and the second measuring rod 200, and scales are arranged on each of the first measuring rod 100, the first telescopic rod 120, the second measuring rod 200 and the second telescopic rod 140.
Two control buttons 600 are respectively arranged in the middle of the first measuring rod 100 and the second measuring rod 200 to facilitate the operation of a measurer.
The working process and principle of the square measuring instrument are as follows: firstly, a theoretical value of a diagonal angle of a room floor to be measured is calculated, then the central shaft 800 is placed at the center of the room floor, when the central shaft is placed, the first measuring rod 100 is positioned below, two ends of the first measuring rod are respectively aligned with a pair of opposite angles of the room floor, and the second measuring rod 200 is positioned above. The second stick 200 is then rotated so that the angle between the second stick 200 and the first stick 100 is equal to the previously calculated theoretical value, based on the reading of the angle dial 700. Finally, two control buttons 600 are pressed, the first telescopic rod 120 and the second telescopic rod 140 slowly extend out of the first measuring rod 100 and the second measuring rod 200, and the control buttons 600 are released after the first telescopic rod 120 and the second telescopic rod 140 abut against the surrounding wall.
After the above operations are completed, the user can visually observe whether the first telescopic rod 120 and the second telescopic rod 140 are just against four corners of the floor of the room. If yes, the floor of the room is proved to be square and is a standard rectangle; if not, the floor of the room is proved to be not square enough and not a standard rectangle.
Meanwhile, the user can also read the scales on the first measuring rod 100, the first telescopic rod 120, the second measuring rod 200 and the second telescopic rod 140, calculate the actual value of the diagonal dimension of the floor of the room, and compare the actual value with the standard value. The closer the actual value is to the standard value, the higher the squareness of the floor of the room is proved.
Further, the first transmission device and the second transmission device each include a gear and a rack that are engaged with each other, the gear is disposed on the output shafts of the first motor 300 and the second motor 400, and the rack is disposed on the first telescopic rod 120 and the second telescopic rod 140. When the gear and the rack are used for transmission, the output shafts of the first motor 300 and the second motor 400 are perpendicular to the first telescopic rod 120 and the second telescopic rod 140.
Thus, the rotational motion of the first motor 300 and the second motor 400 can be converted into the linear motion of the first telescopic rod 120 and the second telescopic rod 140 through the cooperation of the gear and the rack.
The gear and rack meshing transmission is the most widely applied transmission form in mechanical transmission, and has the characteristics of accurate transmission, high efficiency, compact structure, reliable work and long service life. The measuring instrument is a measuring instrument, so the requirements on accuracy and stability are high, and the transmission safety of the gear and the rack can meet the requirements.
Further, a driven wheel 500 is arranged between the first telescopic rod 120 and the second telescopic rod 140, and driven teeth matched with the racks are arranged on the driven wheel 500. Wherein, the driven wheel 500 is rotatably connected to the inner walls of the first measuring stick 100 and the second measuring stick 200.
The driven wheel 500 can support the first telescopic rod 120 and the second telescopic rod 140, so that the first telescopic rod 120 and the second telescopic rod 140 can stably slide.
Further, there are three driven wheels 500, which are uniformly spaced along the length direction of the first telescopic rod 120 or the second telescopic rod 140.
The purpose of this arrangement is to further ensure that the first telescopic rod 120 and the second telescopic rod 140 can stably extend out of the first measuring stick 100 and the second measuring stick 200.
It should be noted that, in this technical solution, the number of the driven wheels 500 may also be set to 2 or 4, and the specific number may be determined according to the lengths of the first measuring stick 100 and the second measuring stick 200.
Further, the first motor 300 and the second motor 400 are both servo motors, the servo motors are connected with servo controllers, the control system comprises a PLC, and the servo controllers are connected with the PLC.
The servo motor is provided with a signal feedback device, the speed of the motor can be measured in real time, the control precision is very high, and the accurate movement of the first telescopic rod 120 and the second telescopic rod 140 can be realized.
It should be noted that, if the requirement for measurement is not particularly high, the motor in the present technical solution may also be a stepping motor, and the cost of the stepping motor is relatively low, and the precise movement of the first telescopic rod 120 and the second telescopic rod 140 may also be basically achieved.
Further, the first motor 300 is disposed at an end of the cavity close to the first protruding opening, and the second motor 400 is disposed at an end of the cavity close to the second protruding opening.
This is done in order to provide as large an effective displacement as possible of the first telescopic rod 120 and said second telescopic rod 140. The effective displacement means that the first telescopic rod 120 and the second telescopic rod 140 can extend out of the actual length of the first measuring rod 100 and the second measuring rod 200, so as to increase the measuring area of the present positive measuring instrument as much as possible.
Further, stoppers are disposed at the first extending opening and the second extending opening of the first measuring rod 100, and fixture blocks corresponding to the stoppers are disposed on the first telescopic rod 120 and the second telescopic rod 140.
Meanwhile, the second measuring stick 200 and the first and second telescopic rods 120 and 140 disposed inside the second measuring stick 200 also have similar structures.
The purpose of the stop block and the clamping block is to prevent the first telescopic rod 120 and the second telescopic rod 140 from being separated from the first measuring rod 100 and the second measuring rod 200 in the telescopic transition, so that the normal operation of the whole squareness measuring instrument is ensured.
Further, the ends of the first telescopic rod 120 and the second telescopic rod 140 extending out of the first measuring rod 100 are hemispherical.

Further, the lengths of the first measuring rod 100, the first telescopic rod 120, the second measuring rod 200 and the second telescopic rod 140 are all 1m-2.5 m.
The length of the squareness measuring instrument is too short, the measurement of a room cannot be finished, the measurement is very inconvenient when the measuring instrument is brought into the room, and the length of 1m-2.5m enables the squareness measuring instrument to measure the squareness of most rooms and to be easily and conveniently brought into the room.
