Description

Technical Field

[0001] This utility model relates to the field of measurement tools, and more specifically, it relates to a measuring ruler for construction completion acceptance. Background Technology

[0002] In engineering acceptance surveying, slope measuring rulers are key tools for accurately determining the angle of a building's inclined surface. The measurement results directly affect the stability of the engineering structure and are a crucial link in ensuring project quality and safety.

[0003] The existing slope measuring ruler still has the following problems when in use: When using a slope measuring ruler, first, the outer casing must be tightly fitted to the surface of the object to be measured. Then, manually and slowly adjust the angle of the ruler while simultaneously observing the status of the internal bubble level. When the bubble moves to the center position, it indicates that a level state has been achieved. At this point, the scale value indicated by the pointer above can be read as the tilt angle. However, since the centeredness of the bubble is judged entirely by visual inspection, visual bias is unavoidable, especially in poor lighting or when the viewing angle is tilted, which can easily lead to misjudgment and thus errors in the final reading, affecting the accuracy and reliability of the measurement. Furthermore, common slope measuring rulers generally lack a stable support structure. During the measurement process, the user must hold the ruler to maintain its position throughout, making it impossible to temporarily place it securely. This design flaw makes it extremely inconvenient when recording data or performing subsequent operations, not only occupying both hands but also easily introducing additional errors due to shaking or movement.

[0004] In view of this, we propose a measuring ruler for construction completion acceptance. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a measuring ruler for construction completion acceptance, so as to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a measuring ruler for construction completion acceptance, comprising a measuring ruler body, two support plates disposed in the middle of the measuring ruler body, a fixed shaft fixedly connected between the two support plates, a rotating sleeve rotatably connected to the fixed shaft, a counterweight pointer fixedly connected to the rotating sleeve, an indicator line disposed at a through hole in the measuring ruler body, a pressing block slidably connected between the two support plates, the pressing block pressing and engaging with the rotating sleeve, a sliding rod slidably connected to the measuring ruler body, the sliding rod being fixedly connected to the pressing block, a spring fixedly connected between the pressing block and the measuring ruler body, and the measuring ruler body being provided with a support structure and a limiting structure.

[0007] The present invention is further configured such that a lever is fixedly connected to the end of the sliding rod.

[0008] The present invention is further configured such that the support structure includes two fixed columns, both of which are fixedly connected to one side of the measuring ruler, and a support rod is rotatably connected to each fixed column, and a torsion spring is fixedly connected between the support rod and the fixed column.

[0009] The present invention is further configured such that the measuring ruler body is fixedly connected to a fixing plate, the fixing plate is slidably connected to a connecting rod, the connecting rod is fixedly connected to a limiting shell, and the limiting shell is limitedly engaged with the two supporting rods.

[0010] The present invention is further configured such that inclined surfaces are provided on both sides of the limiting shell.

[0011] The present invention is further configured such that a second spring is fixedly connected between the limiting shell and the fixing plate.

[0012] The present invention is further configured such that the limiting structure includes a spline rod, the spline rod is splinedly connected to a pressing member, and a spring is fixedly connected between the pressing member and the measuring ruler body.

[0013] The present invention is further configured such that the spline rod is fixedly connected to a threaded rod, the threaded rod is threadedly connected to a rotating wheel, the rotating wheel is rotatably connected to a connecting sleeve, and the connecting sleeve abuts against the extrusion piece.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a measuring ruler for construction completion acceptance, which has the following beneficial effects: 1. This utility model improves measurement accuracy through a unique gravity-adaptive pointer design. Specifically, during measurement, pulling the lever releases the locking of the squeezing block onto the rotating sleeve, allowing the counterweight pointer to hang naturally under pure gravity, directly indicating the tilt angle and eliminating human error caused by the traditional method of visually judging bubble centering. Simultaneously, in the non-measuring state, the squeezing block applies friction to the rotating sleeve under the action of spring one, effectively locking the pointer and preventing it from swinging arbitrarily. This protects the internal mechanism and ensures the stability of the initial state, laying the foundation for accurate measurement.

[0015] 2. In operation, the user can repeatedly and briefly contact the rotating sleeve with the lever by pulling it back and forth. The friction will quickly consume the energy of the counterweight pointer's reciprocating swaying due to inertia, allowing it to reach a stationary state in a short time, thereby quickly reading a stable reading.

[0016] 3. This utility model uses an upward pulling limit shell and a torsion spring to automatically unfold the support rod, which can stably support the measuring ruler on an inclined surface. More importantly, by driving the extrusion component to move linearly through a rotating wheel, the two support rods can be firmly clamped to form a stable triangular support, ensuring that the measuring ruler body remains vertical even when no one is holding it. This frees the operator's hands, facilitates data recording or other auxiliary work, and improves the convenience and safety of use. Attached Figure Description

[0022] Please see Figures 1-5 A measuring ruler for construction completion acceptance includes a measuring ruler body 1, two support plates 2 in the middle of the measuring ruler body 1, a fixed shaft 3 fixedly connected between the two support plates 2, a rotating sleeve 4 rotatably connected to the fixed shaft 3, a counterweight pointer 5 fixedly connected to the rotating sleeve 4, an indicator line 6 provided at the through hole of the measuring ruler body 1, a pressing block 7 slidably connected between the two support plates 2, the pressing block 7 pressing and engaging with the rotating sleeve 4, a sliding rod 8 slidably connected to the measuring ruler body 1, the sliding rod 8 fixedly connected to the pressing block 7, a spring 9 fixedly connected between the pressing block 7 and the measuring ruler body 1, the measuring ruler body 1 is provided with a support structure and a limiting structure; a lever 10 is fixedly connected to the end of the sliding rod 8.

[0023] Please see Figure 1 and Figure 4 The support structure includes two fixed columns 11, both of which are fixed to one side of the measuring scale. The fixed columns 11 are rotatably connected to support rods 12, and torsion springs 13 are fixed between the support rods 12 and the fixed columns 11. The measuring scale body 1 is fixed to a fixed plate 14, and a connecting rod 15 is slidably connected to the fixed plate 14. The connecting rod 15 is fixed to a limiting shell 16, which is in a limiting fit with the two support rods 12. Inclined surfaces are provided on both sides of the limiting shell 16. A second spring 17 is fixed between the limiting shell 16 and the fixed plate 14.

[0024] Please see Figure 4 and Figure 5 The limiting structure includes a spline rod 18, which is splinedly connected to an extrusion member 19. A spring 20 is fixed between the extrusion member 19 and the measuring scale body 1. A threaded rod 21 is fixedly connected to the spline rod 18, which is threadedly connected to a rotating wheel 22. The rotating wheel 22 is rotatably connected to a connecting sleeve 23, which abuts against the extrusion member 19.

[0025] The working principle of this utility model: In use, the width is measured by measuring the lower side of the ruler body 1. When it is necessary to measure the tilt angle of the inclined surface of a building, the ruler body 1 is placed on the inclined surface, and then the lever 10 is pulled. The lever 10 drives the sliding rod 8 to slide along the ruler body 1. The sliding rod 8 drives the pressing block 7 to slide along the two support plates 2. The spring 9 is compressed. After the pressing block 7 loses contact with the rotating sleeve 4, under the action of the gravity of the counterweight pointer 5, the counterweight pointer 5 is made parallel to the direction of gravity. The indicator line 6 pointed to by the counterweight pointer 5 is the tilt angle of the inclined surface of the building. This method adjusts the counterweight pointer 5 only by gravity, thereby improving the test accuracy.

[0026] Initially, the squeezing block 7 squeezes the rotating sleeve 4, thereby limiting the rotating sleeve 4 and the counterweight pointer 5 and improving the stability of the counterweight pointer 5. During use, the lever 10 is pulled back and forth, causing the lever 10 to contact the rotating sleeve 4 multiple times, reducing the back-and-forth shaking of the counterweight pointer 5 due to inertia, thereby enabling the rotating sleeve 4 and the counterweight pointer 5 to remain stationary for a short time and improving testing efficiency.

[0027] During the test, if it is necessary to place and record the reading of the measuring ruler body 1, pull the limiting shell 16 upward to release the limiting shell 16 from limiting the two support rods 12. The limiting shell 16 moves along the line of the fixed plate 14 through the two connecting rods 15. The spring 17 is compressed, and the two support rods 12 rotate to both sides along the fixed column 11 under the torsion of the torsion spring 13 until the support rods 12 are placed on the inclined surface. During the above process, the manual needs to keep the side ruler body in a vertical state.

[0028] When the limiting shell 16 is released, the limiting shell 16 returns to its original position under the elastic force of the second spring 17. The rotating wheel 22 then rotates, moving along the threaded rod 21. The rotating wheel 22, through the connecting sleeve 23, pushes the pressing member 19 along the splined rod 18, compressing the third spring 20. The pressing member 19 then presses against the two support rods 12, ensuring their support positions. When the measuring scale body 1 is released, it remains vertical. After measurement, the rotating wheel 22 is rotated in the opposite direction, releasing the pressing member 19 from the two support rods 12. The pressing member 19 returns to its original position under the elastic force of the third spring 20, causing the two support rods 12 to swing back to their initial state. The limiting shell 16 then limits the movement of the two support rods 12.

For all the fixed connections mentioned above, welding is preferred.
