[0002] In the supervision of construction project quality, measuring devices are an indispensable core tool. Their performance directly affects the accuracy and reliability of the project quality inspection data. Whether it is the angle calibration of building structures, the measurement of dimensions, or the precision control of construction slope, all of these tasks require the use of professional measuring devices.

[0003] A search revealed that Chinese Patent Publication No. CN216621138U discloses a measuring device for supervising the quality of construction projects. The device includes an adjustment knob, a rotating rod, a rotating disk, and a connecting rod. The adjustment rod rotates, causing a scale to rotate and align with the slope. Under the action of a pointer, the scale is aligned with the corresponding value on the dial, enabling rapid measurement of the slope's inclination. This device is highly practical.

[0004] However, in actual use, the scale of the aforementioned equipment is not reliably stored and fixed. It is prone to displacement and collision due to shaking during handling or storage, which may not only affect the measurement accuracy of the scale but also pose a risk of damage. This makes it difficult to meet the strict requirements for the storage stability of measuring devices in construction engineering quality supervision. Therefore, a measuring device for construction engineering quality supervision is proposed to solve the above problems. Utility Model Content

The limiting component includes a mounting groove, which is located on the back of the base. The inner wall of the mounting groove has a movable groove, and the inner wall of the movable groove has a moving groove. A spring is fixedly connected to the inner wall of the movable groove, and a clip is fixedly connected to the end of the spring. A moving block is fixedly connected to the side of the clip, and a slot is provided on the side of the scale.

[0007] As a further description of the above technical solution: The connecting assembly includes a movable rod, which is rotatably connected to the back of the scale. A connecting rod is inserted inside the movable rod, and a limit pin is engaged on the side of the movable rod. A connecting groove is provided on the back of the scale.

[0008] As a further description of the above technical solution: The pointer is located inside the slide groove, and the position of the slot corresponds to the position of the center of the scale.

[0009] As a further description of the above technical solution: The card has an inclined surface on its front and is disposed inside the movable slot.

[0010] As a further description of the above technical solution: The movable block is disposed inside the movable slot, and the size of the mounting slot is adapted to the size of the scale.

[0011] As a further description of the above technical solution: The upper surface of the base is provided with a storage component, which includes a storage slot. The storage slot is opened on the upper surface of the base, and a placement slot is opened on the upper surface of the base.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a measuring device for supervising the quality of construction projects, comprising a base 1, a scale 2 fixedly connected to the upper surface of the base 1, a connecting component 3 rotatably connected to the back of the scale 2, the connecting component 3 including a movable rod 301 rotatably connected to the back of the scale 2, a connecting rod 302 inserted inside the movable rod 301, a limit pin 303 engaged on the side of the movable rod 301, a connecting groove 304 on the back of the scale 4, wherein the connecting rod 302 is detachably connected inside the connecting groove 304, thereby allowing the scale 4 to be detached, and the connecting rod 302 can be pulled to extend out of the movable rod 301, and the limit pin 303 passes through the limit hole provided on the side of the movable rod 301 and the connecting rod 302, a sliding groove 5 on the front of the scale 2, a scale 4 detachably connected to the end of the connecting component 3, a pointer 6 fixedly connected to the side of the connecting component 3, the pointer 6 being disposed inside the sliding groove 5, and a limit component 8 provided on the back of the base 1.

[0020] Reference Figures 4-6 The limiting component 8 includes a mounting groove 801, which is located on the back of the base 1. The size of the mounting groove 801 is adapted to the size of the scale 4. A movable groove 802 is provided on the inner side of the mounting groove 801, and a sliding groove 803 is provided on the inner side of the movable groove 802. A spring 804 is fixedly connected to the inner side of the movable groove 802. The spring 804 allows the locking piece 805 to extend out of the movable groove 802. The locking piece 805 is fixedly connected to the end of the spring 804. The front of the locking piece 805 is provided with an inclined surface. The locking piece 805 is located inside the movable groove 802. When the scale 4 is inserted into the mounting groove 801, it will engage the locking piece. The spring 805 is pressed, which causes the locking piece 805 to retract into the movable groove 802. Then, after the scale 4 is fully inserted into the mounting groove 801, the elastic force of the spring 804 pushes the locking piece 805 into the locking groove 807, thereby limiting the scale 4. The side of the locking piece 805 is fixedly connected to a moving block 806, which is located inside the movable groove 803. The operator can move the moving block 806 to move the locking piece 805 inside the movable groove 802. The side of the scale 4 has a locking groove 807, and the position of the locking groove 807 corresponds to the position of the center of the scale 4, which allows the locking piece 805 to be inserted into the locking groove 807.

[0021] Reference Figure 1 , Figure 3 and Figure 6The upper surface of the base 1 is provided with a storage component 7, which includes a storage slot 701. The storage slot 701 is located on the upper surface of the base 1, and its size is adapted to the size of the movable rod 301. This allows the connecting rod 302 to be retracted into the movable rod 301 and then fixed by a limiting pin 303. Rotating the movable rod 301 allows it to retract into the storage slot 701. The upper surface of the base 1 is provided with two placement slots 703. The slots 703 are symmetrically arranged around the center of the base 1, and the position of the slots 703 corresponds to the position of the pointer 6. After the movable rod 301 is retracted into the storage slots 701, the pointer 6 is just inserted into the storage slots 703. The inner wall of the storage slots 701 is fixedly connected to the protrusions 702, which are made of rubber. The protrusions 702 are designed so that the fixed holes on the top of the connecting rod 302 can be inserted into the protrusions 702, thereby limiting the movable rod 301. This makes the device more convenient to carry.

[0022] Working principle: First, the movable block 806 pulls the clamp 805 to remove the scale 4 from the mounting slot 801. Then, the connecting rod 302 is pulled out of the movable rod 301 to the required length. A limiting pin 303 is passed through the limiting holes of the movable rod 301 and the connecting rod 302 to fix their relative positions. Next, the connecting rod 302 is aligned with the connecting slot 304 of the scale 4 and secured with bolts, completing the assembly of the measuring component. The movable rod 301 is rotated to allow the outer surface of the scale 4 to conform to the slope, causing the pointer 6 to move within the groove 5 of the scale 2. Angle data is read from the scale indicated by the pointer 6. After measurement, the components are disassembled. Remove the scale 4 and place it into the mounting slot 801 on the back of the base 1. The clip 805 automatically engages with the slot 807 of the scale 4 under the action of the spring 804, thus securing the scale 4. Then, pull out the limiting pin 303 and retract the connecting rod 302 into the movable rod 301. Secure it again with the limiting pin 303 and rotate the movable rod 301 to retract it into the storage slot 701. At this time, the pointer 6 engages with the corresponding placement slot 703, and the fixing hole at the top of the connecting rod 302 engages with the rubber protrusion 702 in the storage slot 701, thus securing the movable rod 301. Finally, the entire unit is stored and made easy to carry.
