Description

Technical Field

[0001] The utility model patent relates to the technical field of electric power engineering, and mainly relates to an electric power engineering measuring ruler. Background Art

[0002] In power distribution network projects, many tools and instruments are used to build transformer substations, and multiple sets of data need to be collected. Therefore, construction workers often need to carry multiple measuring tools such as tape measures and rulers when working, which brings great inconvenience to their work.

[0003] However, the existing measuring rulers used in power distribution network projects have a single measurement effect, and various tools need to be replaced during operation. Replacing tools not only affects the construction speed, but also easily causes measurement deviation during the replacement process, resulting in inaccurate measurement. In this regard, we propose a power engineering measuring ruler. Utility Model Content

Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0022] For example, please refer to Figure 1-5 A power engineering measuring ruler comprises a first scale 10, one side of the first scale 10 is connected to a protractor 40, one side of the protractor 40 is rotatably connected to a second scale 20, one side of the second scale 20 and the first scale 10 are connected to a marking device 30, the marking device 30 comprises a threaded rod 31 rotatably connected to one side of the second scale 20 and the first scale 10, a support platform 32 connected to one side of the threaded rod 31, an I-shaped slider 33 slidably connected to the top of the support platform 32 and a support plate 34 connected to both sides of the top of the I-shaped slider 33, the top of the support plate 34 is rotatably connected to a marking pen 36, and both sides of the marking pen 36 are connected to torsion springs 35.

[0023] It should be noted that, in the embodiment, the rotation of the threaded rod 31 drives the support platform 32 to move, thereby adjusting the position of the marking pen 36. The position of the marking pen 36 is further adjusted by moving the I-shaped slider 33 to avoid the positions of the second scale 20 and the first scale 10 being difficult to mark. The marking pen 36 is rotated to leave a mark on the object, and the marking pen 36 is reset by the elastic force of the torsion spring 35.

[0024] For example, please refer to Figure 1 and Figure 5 A threaded hole is provided on one side of the I-shaped slide block 33 , and the hole body of the threaded hole is rotatably connected to a positioning screw 50 , and a rubber pad is provided on one side of the positioning screw 50 .

[0025] It should be noted that, in the embodiment, the positioning screw 50 is rotated so that the rubber pad of the positioning screw 50 contacts the support platform 32, so that the I-shaped slider 33 is fixed, thereby avoiding position errors caused by the marking pen 36 when marking.

[0026] For example, please refer to Figure 5 A T-shaped slide groove 321 is provided on the top of the support platform 32 , and the groove body of the T-shaped slide groove 321 is slidably connected to the I-shaped slide block 33 .

[0027] It should be noted that, in the embodiment, the T-shaped slide groove 321 limits the position of the I-shaped slide block 33 .

[0028] For example, please refer to Figure 3 and Figure 5 A pointing rod 331 is fixed to one side of the I-shaped slider 33, and the pointing rod 331 is L-shaped.

[0029] It should be noted that, in the embodiment, the pointing rod 331 facilitates observation of the position of the marking pen 36 to avoid deviation in the reading.

[0030] For example, please refer to Figure 2A rotating block 311 is fixed to one side of the threaded rod 31 , and a plurality of anti-slip grooves are provided on the outer wall of the rotating block 311 .

[0031] It should be noted that, in the embodiment, the rotating block 311 facilitates the rotation of the threaded rod 31 , and the anti-slip groove plays an anti-slip role.

[0032] For example, please refer to Figure 1 A central groove 21 is provided on one side of the second scale 20, and the second scale 20 and the first scale 10 are transparent.

[0033] It should be noted that, in the embodiment, the central groove 21 facilitates the protractor 40 to measure the angle between the second scale 20 and the first scale 10, and the second scale 20 and the first scale 10 are transparent to facilitate angle observation.

[0034] For example, please refer to Figure 3 A pressing strip 361 is fixed to one side of the top of the marking pen 36 .

[0035] It should be noted that, in the embodiment, the pressing bar 361 facilitates the marking pen 36 to rotate and mark the measuring position.

[0036] The specific operation mode of the utility model is as follows:

[0037] The above-mentioned electric power engineering measuring ruler places the second scale 20 and the first scale 10 on the surface of the object to be measured, measures the angle between the second scale 20 and the first scale 10 by using a protractor 40, drives the support platform 32 to move by rotating the threaded rod 31, thereby adjusting the position of the marking pen 36, and further adjusts the position of the marking pen 36 by moving the I-shaped slider 33 to avoid the positions of the two ends of the second scale 20 and the first scale 10 being difficult to mark, rotates the positioning screw 50 to make the rubber pad contact the support platform 32, fixes the I-shaped slider 33, leaves a mark on the object by rotating the marking pen 36, and resets the marking pen 36 by the elastic force of the torsion spring 35.

[0038] The above-described embodiments only express the implementation methods of the present application, but for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
