Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology, specifically a length measuring device for cement poles. Background Technology

[0002] As the name suggests, a utility pole is a pole used to carry power lines. They appear in rural areas, fields, roads, and streets, and are one of China's important infrastructure projects. Early utility poles were mostly made of wood, but with the development of reinforced concrete and technological advancements, most utility poles today are made of concrete. Concrete utility poles are mostly frustum-shaped structures, thicker at one end and thinner at the other, with an internal cavity. The thicker end has a notch, while the thinner end is sealed.

[0003] Before installation, utility poles need to be measured. In the existing technology, most measurements are taken with a measuring tape. However, since utility poles are truncated cones, measuring their length requires two people and the measurement accuracy is not high. Therefore, there is an urgent need for a length measuring device for cement utility poles to solve the above problems. Utility Model Content

[0040] 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.

[0041] In this embodiment of the utility model, please refer to Figures 1 to 3 A length measuring device for cement poles, comprising a connecting plate 1, and further comprising:

[0042] The positioning mechanism is connected to the connecting plate 1;

[0043] Fixed bending rod 8, one end of which is connected to connecting plate 1;

[0044] The telescopic rod 9 is connected to the other end of the fixed folding rod 8;

[0045] The fixing mechanism, connected to the telescopic rod 9, is used to fix the outer shell of the measuring tape;

[0046] The abutment plate 14 is connected to the fixed bending rod 8 and abuts against the outer wall of the thick end of the utility pole;

[0047] The measuring tape end fixing mechanism is connected at one end to the fixing folding rod 8 and at the other end to the telescopic rod 9, and is used to fix the end of the measuring tape.

[0048] The connecting plate 1 is fixed by the positioning mechanism and is located at the center of the thicker end. The abutment plate 14 abuts against the outer wall of the thicker end of the utility pole. The fixing mechanism fixes the measuring tape and the measuring tape head fixing mechanism fixes the end of the measuring tape. The telescopic rod 9 is pulled to unfold the measuring tape and measure the length of the utility pole. The telescopic rod 9 ensures that the measuring tape and the central axis of the utility pole are always in a straight line parallel to each other during the movement of the measuring tape.

[0049] In this embodiment, the measuring tape consists of a measuring tape shell and a measuring tape. The measuring tape is wound inside the measuring tape shell, with one end connected to it. The other end of the measuring tape is exposed outside the measuring tape shell. A fixing mechanism fixes the measuring tape shell, thereby fixing the measuring tape body. A tape head fixing mechanism fixes the tape head exposed to the outside. When the fixing mechanism drives the measuring tape shell to move, the measuring tape unwinds and its length increases because the tape head is fixed by the tape head fixing mechanism, allowing for measurement.

[0050] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 The positioning mechanism includes:

[0051] A bidirectional threaded rod 2 is rotatably connected to a connecting plate 1, and the bidirectional threaded rod 2 is provided with threaded grooves in opposite directions;

[0052] Threaded block 3 is threadedly connected to bidirectional threaded rod 2;

[0053] Support rod 4, one end of which is hinged to threaded block 3;

[0054] Fixed plate 5 is hinged to the other end of support rod 4;

[0055] Arc block 6 is connected to fixed plate 5;

[0056] Telescopic folding rod 7, one end is connected to connecting plate 1, and the other end is connected to fixing plate 5.

[0057] Hold the fixed folding rod 8 so that the abutment plate 14 abuts against the outer wall of the thicker end of the utility pole. Rotate the double-threaded rod 2. Under the limit of the telescopic folding rod 7, the threaded block 3 moves. The threaded block 3 drives the support rod 4 to move. The support rod 4 drives the fixed plate 5 to unfold on the outside. The fixed plate 5 drives the arc block 6 to move to abut against the inner wall of the thicker end of the utility pole, thereby fixing the device.

[0058] As one embodiment of this utility model, please refer to Figure 1 and Figure 3 The fixing mechanism includes:

[0059] Connecting lever 10, one end of which is connected to telescopic lever 9;

[0060] Sliding sleeve 11 is slidably connected to connecting folding rod 10;

[0061] Fixed plate 12 is connected to sliding sleeve 11;

[0062] The elastic element 13 is connected at one end to the connecting folding rod 10 and at the other end to the fixing plate 12.

[0063] The measuring tape is placed between two sets of fixing plates 12. The measuring tape shell presses against the fixing plates 12 on both sides. The fixing plates 12 drive the sliding sleeve 11 to move while pressing the elastic element 13, causing the elastic element 13 to undergo elastic deformation. Under the reaction force of the elastic element 13, the fixing plates 12 fix the measuring tape. The elastic element 13 can be a spring, sheet metal, etc.

[0064] As one embodiment of this utility model, please refer to Figure 1 and Figure 3 The ruler-head fixing mechanism includes:

[0065] The end fixing plate 15 is connected to the fixing folding plate 8;

[0066] Sliding sleeve 16 is slidably connected to fixed folding rod 8;

[0067] Elastic element 2 17, one end is connected to sliding sleeve 2 16, and the other end is connected to telescopic rod 9;

[0068] Limiting plate 18 is connected to sliding sleeve 16.

[0069] Pulling the sliding sleeve 16 causes it to move, and simultaneously, the elastic element 17 undergoes elastic deformation, locking one end of the measuring tape onto the end fixing plate 15. Releasing the sliding sleeve 16 allows the limiting plate 18 to cooperate with the end fixing plate 15 to fix one end of the measuring tape under the reaction force of the elastic element 17. The elastic element 17 can be a spring, a sheet spring, or the like.

[0070] As one embodiment of this utility model, please refer to Figure 1 and Figure 3 It also includes:

[0071] Pointer 19 is connected to telescopic rod 9;

[0072] Telescopic folding rod 20, one end of which is connected to telescopic rod 9;

[0073] Positioning plate 21 is connected to the other end of telescopic folding rod 20.

[0074] The telescopic rod 9 drives the telescopic folding rod 20 to move laterally, which in turn drives the positioning plate 21 to move laterally. The positioning plate 21 can move vertically. When the positioning plate 21 comes into contact with the thinner end of the utility pole, the length of the utility pole is the value indicated by the measuring tape on the pointer 19.

[0075] The working principle of this utility model is as follows: Hold the fixed bending rod 8 so that the abutment plate 14 abuts against the outer wall of the thicker end of the utility pole. Rotate the bidirectional threaded rod 2. Under the limitation of the telescopic bending rod 7, the threaded block 3 moves. The threaded block 3 drives the support rod 4 to move. The support rod 4 drives the fixed plate 5 to unfold outwards. The fixed plate 5 drives the arc block 6 to move until it abuts against the inner wall of the thicker end of the utility pole, thus fixing the device. Place the measuring tape between the two sets of fixed plates 12. The measuring tape shell presses against the two fixed plates 12. The fixed plates 12 drive the sliding sleeve 11 to move while pressing against the elastic element 13, causing the elastic element 13 to undergo elastic deformation. The reaction force of the elastic element 13... The fixed plate 12 fixes the measuring tape. Pulling the sliding sleeve 16 causes it to move. At the same time, the elastic element 17 undergoes elastic deformation, locking one end of the measuring tape onto the end fixed plate 15. Releasing the sliding sleeve 16 allows the limiting plate 18 to cooperate with the end fixed plate 15 to fix one end of the measuring tape under the reaction force of the elastic element 17. Pulling the telescopic rod 9 causes the measuring tape to unfold and measure the length of the utility pole. The telescopic rod 9 ensures that the measuring tape is always parallel to the central axis of the utility pole during its movement. When the positioning plate 21 abuts against the thinner end of the utility pole, the value indicated by the pointer 19 on the measuring tape is the length of the utility pole.
