Description

Technical Field

[0001] The utility model relates to the field of measuring devices, in particular to a scale for measuring the spacing of steel bars. Background Technique

[0002] Steel bars are long-shaped steel materials widely used in construction projects, especially in reinforced concrete structures and prestressed concrete structures. Its main function is to improve the strength and bearing capacity of concrete, making the building more firm and stable.

[0003] At many construction sites, such as tunnels and bridges, multiple rows of steel bars are used. In order to improve the construction quality, the distance between two steel bars needs to meet relevant regulations, so it is necessary to measure the spacing between two steel bars.

[0004] When the existing scale for measuring the spacing of steel bars is in use, generally, the measuring distance plate is driven to move by a threaded drive method, and the distance between two steel bars is measured by the spacing between the two distance plates. When using the scale of this method, the position of the distance plate is directly adjusted by a threaded adjustment method. When the spacing between the two distance plates is quite different from the spacing between the two measured steel bars, multiple turns of rotation are required, and the operation is rather inconvenient.

[0005] Therefore, it is necessary to provide a new scale for measuring the spacing of steel bars to solve the above technical problems. Content of the Utility Model

[0006] To solve the above technical problems, the utility model provides a scale for measuring the spacing of steel bars.

[0007] The scale for measuring the spacing of steel bars provided by the utility model includes a mounting plate. One end of the mounting plate is fixedly connected with a second distance plate. The mounting plate is also provided with a mounting groove, on which a sliding device and a guiding device are installed. A threaded ring is installed on the guiding device. A threaded sleeve is threadedly connected to the threaded ring. A first distance plate is fixedly installed on the threaded sleeve. The sliding device drives the threaded ring to slide in the mounting groove. When the threaded ring rotates, it drives the threaded sleeve to move horizontally on the threaded ring.

[0008] Preferably, the sliding device includes a mounting frame in a U-shaped structure, a limiting component, and two connecting rings. The two connecting rings are respectively rotatably sleeved at both ends of the threaded ring. The two ends of the mounting frame are respectively fixedly connected to the two connecting rings. The mounting frame is movably inserted into a through hole opened on the inner wall of the mounting groove. The limiting component is installed on the mounting frame.

[0009] Preferably, the limiting assembly includes a movable frame, a limiting rod and a spring. A slot is provided on the mounting frame. The end of the movable frame is movably inserted into the slot provided on the mounting frame. The limiting rod is fixedly connected to the movable frame. The two ends of the spring are respectively fixedly connected to the end of the movable frame and the bottom wall of the slot of the mounting frame.

[0010] Preferably, the mounting plate is provided with a plurality of equally spaced adjustment slots for the limiting rod to move into.

[0011] Preferably, the guiding device comprises a rotating rod and a guiding rod, the rotating rod being rotatably connected to the mounting plate, a plurality of raised strips being fixedly connected to the outer surface of the rotating rod, a through groove adapted to the plurality of raised strips being provided on the inner wall of the threaded ring, the guiding rod being fixedly installed in the mounting groove, a movable plate being provided on the movable sleeve of the guiding rod, and one end of the movable plate being fixedly connected to the threaded sleeve.

[0012] Preferably, one end of the rotating rod extends to the outside of the mounting groove and is fixedly connected to a handle.

[0013] Preferably, a scale line is arranged on the top of the mounting plate, and a positioning frame with an L-shaped structure is fixedly connected to the first ranging plate, and the top wall of the positioning frame is in contact with the scale line.

[0014] Preferably, one end of the rotating rod extends to the outside of the mounting groove and is fixedly connected to a handle.

[0015] Compared with the related art, the ruler for measuring the spacing between steel bars provided by the utility model has the following beneficial effects:

[0016] The position of the first measuring plate is roughly adjusted by the sliding device, and then the rotating rod drives the threaded ring to rotate. Since the movable plate is fixedly connected to the threaded sleeve, when the threaded ring rotates, the threaded sleeve moves on the threaded ring, thereby accurately adjusting the position of the first measuring plate to facilitate the measurement of the distance between two steel bars. The adjustment of the first measuring plate by the device is not a single thread adjustment, which makes it more convenient for the staff to measure the steel bar distance to a certain extent.

Specific embodiments

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] In the specific implementation process, as Figure 1 - Figure 4 shown, it includes a mounting plate 1. One end of the mounting plate 1 is fixedly connected to a second distance measuring plate 5. The mounting plate 1 is further provided with a mounting groove 2. A sliding device and a guiding device are installed on the mounting groove 2. A threaded ring 3 is installed on the guiding device. A threaded sleeve 6 is threadedly connected to the threaded ring 3. A first distance measuring plate 4 is fixedly installed on the threaded sleeve 6. The sliding device drives the threaded ring 3 to slide in the mounting groove 2. When the threaded ring 3 rotates, it drives the threaded sleeve 6 to move horizontally on the threaded ring 3;

[0024] The sliding device includes a mounting frame 7 in a U-shaped structure, a limiting component, and two connecting rings 8. The two connecting rings 8 are respectively rotatably sleeved at both ends of the threaded ring 3. The two end parts of the mounting frame 7 are respectively fixedly connected to the two connecting rings 8. The mounting frame 7 is movably inserted into a through hole opened on the inner wall of the mounting groove 2. The limiting component is installed on the mounting frame 7. The limiting component includes a moving frame 9, a limiting rod 11, and a spring 10. A slot 19 is opened on the mounting frame 7. The end part of the moving frame 9 is movably inserted into the slot opened on the mounting frame 7. The limiting rod 11 is fixedly connected to the moving frame 9. The two ends of the spring 10 are respectively fixedly connected to the end part of the moving frame 9 and the bottom wall of the slot of the mounting frame 7. The mounting plate 1 is provided with a plurality of equally spaced adjusting grooves 12 for the limiting rod 11 to move into. Pull the moving frame 9, and the moving frame 9 drives the limiting rod 11 to move, so that the end part of the limiting rod 11 moves out of the adjusting groove 12, and the spring 10 is in a stretched state. Then, move the moving frame 9, and the moving frame 9 drives the mounting frame 7 and the two connecting rings 8 thereon to move, thereby driving the threaded ring 3 to move;

[0025] The guide device includes a rotating rod 13 and a guide rod 14. The rotating rod 13 is rotatably connected to the mounting plate 1. One end of the rotating rod 13 extends to the outside of the mounting groove 2 and is fixedly connected to a handle 20. A plurality of raised strips 15 are fixedly connected to the outer surface of the rotating rod 13. A through groove adapted to the plurality of raised strips 15 is provided on the inner wall of the threaded ring 3. The guide rod 14 is fixedly installed in the mounting groove 2. A movable plate 16 is movably sleeved on the guide rod 14. One end of the movable plate 16 is fixedly connected to the threaded sleeve 6. The rotating rod 13 is rotated by the handle 20, and the rotating rod 13 drives the threaded ring 3 to rotate. Since the movable plate 16 is fixedly connected to the threaded sleeve 6, when the threaded ring 3 rotates, the threaded sleeve 6 moves on the threaded ring 3, thereby accurately adjusting the position of the first distance measuring plate 4.

[0026] A scale line 17 is arranged on the top of the mounting plate 1, and a positioning frame 18 with an L-shaped structure is fixedly connected to the first ranging plate 4, and the top wall of the positioning frame 18 is in close contact with the scale line 17. When the first ranging plate 4 moves, the positioning frame 18 thereon is driven to move, and the positioning frame 18 moves in close contact with the scale line 17, which is convenient for reading. In addition, cleaning sponges can be arranged on both sides of the positioning frame 18, and when the positioning frame 18 moves, the cleaning sponge is driven to move, so as to facilitate cleaning of the scale line 17;

[0027] For ease of understanding, it should be noted that, assuming that the spacing between the two steel bars is 10 cm, at this time, the spacing between the first ranging plate 4 and the second ranging plate 5 after adjustment is larger. If the steel bar spacing measured subsequently is 2 cm, it is necessary to reduce the spacing between the first ranging plate 4 and the second ranging plate 5. If it is simply adjusted by rotating the thread, it needs to be rotated multiple times, which is more troublesome to operate. Therefore, the device first roughly adjusts the first ranging plate 4 through the mobile frame, and then accurately adjusts the first ranging plate 4 through the threaded ring, which is more convenient to operate.

[0028] The working principle provided by the utility model is as follows: when the device is used, the position of the first distance measuring plate 4 is adjusted according to the approximate spacing between the two steel bars, the moving frame 9 is pulled, and the moving frame 9 drives the limiting rod 11 to move, so that the end of the limiting rod 11 moves out of the adjustment slot 12, and the spring 10 is in a stretched state, then the moving frame 9 drives the mounting frame 7 and the two connecting rings 8 thereon to move, thereby driving the threaded ring 3 to move, and the movement of the threaded ring 3 drives the threaded sleeve 6 and the first distance measuring plate 4 thereon to move, and after moving to a suitable position, under the action of the spring 10 , the limit rod 11 moves into the adjustment groove 12, the first distance measuring plate 4 and the second distance measuring plate 5 are placed between the two steel bars, the handle 20 is turned, and the rotating rod 13 is driven to rotate by twisting the handle 20, and the rotating rod 13 drives the threaded ring 3 to rotate. Since the movable plate 16 is fixedly connected to the threaded sleeve 6, when the threaded ring 3 rotates, the threaded sleeve 6 moves on the threaded ring 3, so that the position of the first distance measuring plate 4 is accurately adjusted, which is convenient for measuring the distance between the two steel bars. In addition, when the first distance measuring plate 4 moves, it drives the positioning frame 18 thereon to move, and the positioning frame 18 moves in close contact with the scale line 17 to facilitate reading.
