Technical Field
[0001] This utility model relates to the field of measuring device technology, and in particular to a measuring device. Background Technology
[0002] The measuring device is specifically designed for on-site measurement and observation during architectural engineering design. The measuring device consists of a mounting base, support plates, extension plates, pins, and the measuring instrument body. When using the measuring device in architectural engineering design, the three support plates are rotated outwards and placed on the ground. At the same time, the extension of the extension plate is adjusted and fixed with the pins. Then, the measuring instrument body on the mounting base is opened to begin on-site measurement and observation, thus achieving dedicated on-site measurement.
[0003] In their daily work, the inventors discovered that when using the measuring device, due to the unevenness of the ground at the actual measurement point, the mounting base is usually leveled by adjusting the length of the extension plate on the support plate. The length of the extension plate on the support plate is adjusted using a pin and a slot. However, when the adjusted length is between the two slots, it is impossible to fix it effectively with the pin, which may affect the measurement. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that in actual use, due to the unevenness of the ground at the measurement point, the installation base is generally adjusted by adjusting the length of the extension plate on the support plate. However, the length of the extension plate on the support plate is adjusted by using a pin and a slot. When the adjusted length is between the two slots, it is not possible to fix it well and effectively with the pin, which may affect the measurement. Therefore, a special measuring device for architectural engineering design is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a measuring device, comprising a mounting base, a measuring instrument body rotatably mounted on the upper end of the mounting base, a support plate rotatably connected to the arc surface of the mounting base, an extension plate slidably inserted at the other end of the support plate, a protective component provided at the lower end of the extension plate, a fixing component provided on the front side of the support plate, a plurality of evenly distributed slots opened on one side of the extension plate, protrusions provided on the inner wall of the slots, a pin slidably inserted on one side of the support plate, and the fixing component comprising a screw rotatably connected to the inner wall of the support plate, the screw penetrating the extension plate, a square plate threadedly connected to the arc surface of the screw, the square plate sliding on the inner wall of the support plate.
[0006] The effect achieved by the above components is as follows: by setting the fixing components, when the length of the extension plate is adjusted between the two slots, the screw is rotated by the drive mechanism, so that the square plate slides on the inner wall of the support plate to the extension plate, and the other end of the extension plate contacts the ground, thereby fixing the extension plate and thus achieving the effect of fixing the extension plate as much as possible to avoid affecting the measurement.
[0007] Preferably, the support plate has a drive cavity inside, and a worm gear is provided inside the drive cavity. The worm gear is rotatably connected to the screw.
[0008] The effect achieved by the above components is to drive the worm gear in the drive chamber to rotate, thereby causing the screw to rotate.
[0009] Preferably, the worm gear is connected to a worm shaft via an arcuate surface, and the worm shaft is rotatably connected to the support plate.
[0010] The effect achieved by the above components is that the worm rotates, causing the worm wheel inside the drive cavity to rotate.
[0011] Preferably, the other end of the worm gear is fixedly connected to a turntable, and the arc surface of the turntable is provided with friction stripes.
[0012] The effect achieved by the above components is as follows: when the worker rotates the turntable, the worm gear rotates, and magnetic plates are provided on the sides of the extension plate and the square plate that are close to each other. The magnetic plates attract each other, thereby providing auxiliary limiting for the extension plate.
[0013] Preferably, the protective assembly includes a protective shell slidably connected to the surface of the extension plate, wherein a ball is slidably inserted into the inner wall of the protective shell and the ball is inserted into the extension plate.
[0014] The effect achieved by the above components is as follows: dragging the protective shell causes it to be inserted into the surface of the sharp end of the extension plate, so that the ball is inserted into the extension plate, thereby fixing the protective shell and thus minimizing the risk of injury from the sharp end of the extension plate.
[0015] Preferably, a spring is fixedly connected to the arc surface of the sphere, and the other end of the spring is fixed to the protective shell.
[0016] The effect achieved by the above components is to reset the sphere by setting a spring.
[0017] Preferably, a pull rope is fixedly connected to the arc surface of the sphere, and the pull rope passes through the protective shell.
[0018] The effect achieved by the above components is: pulling the pull rope causes the ball to retract completely into the protective shell, and then dragging the protective shell for disassembly.
[0019] Preferably, one end of the pin is fixedly connected to a fixing rope, and the other end of the fixing rope is fixed to the support plate.
[0020] The effect achieved by the above components is to limit the position of the pin by setting a fixing rope.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] In this invention, by setting a fixing component, when the length of the extension plate is adjusted to be between the two slots, the drive mechanism causes the screw to rotate, causing the square plate to slide on the inner wall of the support plate to the extension plate. The other end of the extension plate contacts the ground, thereby fixing the extension plate. This achieves the goal of fixing the extension plate as much as possible to avoid affecting the measurement. It solves the problem that when the ground at the actual measurement point is uneven, the installation base is usually adjusted by adjusting the length of the extension plate on the support plate. However, the length of the extension plate on the support plate is adjusted using a pin and slots. But when the adjusted length is between the two slots, it is not possible to fix it well with the pin, which may affect the measurement. Attached Figure Description

[0028] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a special measuring device for architectural engineering design includes a mounting base 1, a measuring instrument body 4 rotatably mounted on the upper end of the mounting base 1, a support plate 5 rotatably connected to the arc surface of the mounting base 1, an extension plate 6 slidably inserted at the other end of the support plate 5, a protective component 3 provided at the lower end of the extension plate 6, a fixing component 2 provided on the front side of the support plate 5, a plurality of evenly distributed slots 7 opened on one side of the extension plate 6, protrusions provided on the inner wall of the slots 7, and a pin 8 slidably inserted on one side of the support plate 5.
[0029] The following section will explain the specific settings and functions of the fixing component 2 and the protective component 3.
[0030] Reference Figure 3As shown in this embodiment: the fixing component 2 includes a screw 21 rotatably connected to the inner wall of the support plate 5. The screw 21 passes through the extension plate 6, and a square plate 22 is threadedly connected to the arc surface of the screw 21. The square plate 22 slides on the inner wall of the support plate 5. By setting the fixing component 2, when the length of the extension plate 6 is adjusted to be between the two slots 7, the screw 21 is rotated by the driving mechanism, causing the square plate 22 to slide on the inner wall of the support plate 5 to the extension plate 6. The other end of the extension plate 6 contacts the ground, thereby fixing the extension plate 6 and thus achieving the effect of fixing the extension plate 6 as much as possible to avoid affecting the measurement. A driving cavity 23 is opened inside the support plate 5. The drive cavity 23 is equipped with a worm gear 24, which is rotatably connected to the screw 21. When the worm gear 24 rotates in the drive cavity 23, the screw 21 rotates. The arc surface of the worm gear 24 is meshed with a worm 25, which is rotatably connected to the support plate 5. When the worm 25 rotates, the worm gear 24 rotates in the drive cavity 23. The other end of the worm 25 is fixedly connected to a turntable 26. The arc surface of the turntable 26 is provided with friction stripes 27. When the worker rotates the turntable 26, the worm 25 rotates. Magnetic sheets are provided on the sides of the extension plate 6 and the square plate 22 that are close to each other. The magnetic sheets attract each other, thereby providing auxiliary limiting for the extension plate 6.
[0031] Reference Figure 4 As shown in this embodiment: the protective component 3 includes a protective shell 31 slidably connected to the surface of the extension plate 6. A ball 32 is slidably inserted into the inner wall of the protective shell 31. The ball 32 is inserted into the extension plate 6. Dragging the protective shell 31 causes it to be inserted into the sharp end surface of the extension plate 6, thus fixing the protective shell 31 and minimizing the risk of injury from the sharp end of the extension plate 6. A spring 33 is fixedly connected to the arc surface of the ball 32. The other end of the spring 33 is fixed to the protective shell 31. By setting the spring 33, the ball is reset. A pull rope 34 is fixedly connected to the arc surface of the ball 32. The pull rope 34 passes through the protective shell 31. Pulling the pull rope 34 causes the ball 32 to be completely retracted into the protective shell 31. Then, the protective shell 31 is dragged to disassemble. One end of the pin 8 is fixedly connected to a fixing rope 9. The other end of the fixing rope 9 is fixed to the support plate 5. By setting the fixing rope 9, the pin 8 is limited.
[0032] Working principle:
[0033] When using a measuring device in architectural engineering design, the three support plates 5 are rotated outwards and placed on the ground. Simultaneously, the extension plate 6 is adjusted and secured with pins 8. Then, the measuring instrument body 4 (model Liangce GCL-32X) on the mounting base 1 is opened to begin on-site measurement and observation, thus achieving dedicated on-site measurement. When the length of the extension plate 6 is adjusted to be between the two slots 7, the worker rotates the turntable 26, causing the worm gear 25 to rotate. This rotates the worm wheel 24 in the drive cavity 23, causing the screw 21 to rotate. This causes the square plate 22 to slide against the inner wall of the support plate 5 to the extension plate 6, with the other end of the extension plate 6 contacting the ground, thereby securing the extension plate 6. To achieve the goal of fixing the extension plate 6 as much as possible and avoiding interference with the measurement, magnetic sheets are provided on the sides of the extension plate 6 and the square plate 22 that are close to each other. The magnetic sheets attract each other, thereby providing auxiliary limiting for the extension plate 6. Dragging the protective shell 31 allows it to be inserted into the sharp end surface of the extension plate 6, causing the ball 32 to be inserted into the extension plate 6, thereby fixing the protective shell 31 and thus minimizing the risk of injury from the sharp end of the extension plate 6. A spring 33 is used to reset the ball. Pulling the pull rope 34 causes the ball 32 to be completely retracted into the protective shell 31. Then, the protective shell 31 is dragged to disassemble it. A fixing rope 9 is used to limit the pin 8.
