Description

Technical Field

[0001] This utility model relates to the field of engineering management, and more specifically, to a portable measuring ruler for engineering management. Background Technology

[0002] Engineering management is a management system that takes engineering projects and their resources as its objects and uses systematic theories and methods to efficiently plan, organize, implement, and control projects in order to achieve engineering goals. In the field of engineering management, measuring rulers are sometimes needed to measure the length of the target.

[0003] A search revealed that Chinese Patent Publication No. CN219265203U discloses "a portable measuring ruler for architectural surveying, comprising an angle ruler, wherein the angle ruler has rotating grooves on both sides of the front top of the angle ruler, and straight grooves on both sides of the middle front of the angle ruler, with a straight ruler disposed within the straight grooves, one end of the straight ruler being rotatably connected to the straight groove via a rotating shaft, and fixing blocks being fixedly connected to the top and bottom of the rotating shaft, and a sliding groove being disposed in the middle of the straight ruler. In this utility model, when drawing architectural survey paper, the measuring ruler is placed on the paper, and when an angle needs to be measured, the calibration groove is aligned with the measurement point, and the angle on the angle ruler can be used for measurement. When a length needs to be measured, the flat angle face of the angle ruler can be used for measurement and drawing. In architectural engineering surveying, multiple rulers are often needed to complete the drawing of some areas, thus meeting people's needs and not affecting construction efficiency." However, the following defects still exist:

[0004] When using this measuring ruler, one end of the extension ruler is not fixed. When the extension ruler is rotated into the straight groove, if the worker picks up the measuring ruler with the extension ruler facing down, the extension ruler will easily detach from the straight groove, thus hindering the worker's measurement.

[0005] Therefore, we made improvements and proposed a portable measuring ruler for engineering management. Utility Model Content

[0006] The purpose of this utility model is to address the problem that, when using a portable measuring ruler for engineering management, one end of the extension ruler is not fixed. When the extension ruler is rotated into the straight groove, if the worker picks up the measuring ruler with the extension ruler facing down, the extension ruler will easily detach from the straight groove, thus hindering the worker's measurement.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] Portable measuring rulers for engineering management aim to improve the above-mentioned problems.

[0009] The specific details of this utility model are as follows:

[0010] The device includes an angle ruler, a storage groove on the side wall of the angle ruler, an isolation block fixedly connected to the inner wall of the storage groove, a ruler hinged to one end of the storage groove, a cavity on the side wall of the ruler, a fixing plate fixedly connected to the inner wall of the cavity, a sliding rod slidably connected inside the fixing plate, a stop block fixedly connected to the end of the sliding rod away from the fixing plate, a spring sleeved on the outside of the sliding rod, and a hemispherical block fixedly connected to the side wall of the isolation block near the ruler, and a hemispherical groove on the side wall of the stop block.

[0011] As a preferred technical solution of this utility model, a first extension ruler is provided on the side of the storage groove away from the ruler. A second extension ruler is hinged to one end of the first extension ruler. A first sliding plate and a second sliding plate are fixedly connected to the side walls of the first extension ruler and the second extension ruler, respectively. A convex groove is provided on the side wall of the storage groove. The shapes of the first sliding plate and the second sliding plate are two oppositely arranged "L" shapes.

[0012] As a preferred technical solution of this utility model, a fixing rod is fixedly connected to one end of the storage groove away from the ruler, a coil spring is sleeved on the outside of the fixing rod, a baffle is fixedly connected to the top of the coil spring, and the bottom end of the coil spring is fixedly connected to the bottom of the storage groove.

[0013] As a preferred technical solution of this utility model, the inside of the angle ruler is fixedly connected to a handle, and the top of the handle is fixedly connected to a level.

[0014] As a preferred technical solution of this utility model, a nail groove is provided on the side wall of the abutment block.

[0015] As a preferred technical solution of this utility model, the angle ruler, straight ruler, first extension ruler and second extension ruler are all made of acrylic.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the solution of this utility model:

[0018] 1. The system consists of a storage slot, a partition block, a ruler, a cavity, a fixing plate, a sliding rod, a stop block, and a spring. When the ruler is retracted into the storage slot, the worker presses the stop block, causing it to move towards the cavity. At this point, the spring contracts until the stop block is in contact with one end of the ruler. The ruler is then rotated into the storage slot, and the stop block is released. The spring force causes the stop block to firmly press against the partition block, thus fixing the ruler in place. This prevents the ruler from detaching from the storage slot when using an angle gauge, which would affect the measurement operation.

[0019] 2. With the first extension ruler, second extension ruler, first sliding plate, second sliding plate, and convex groove set up, if it is inconvenient to use a ruler, the first extension ruler, second extension ruler, first sliding plate, and second sliding plate can be pulled out from the inside of the storage groove and convex groove, so that the first extension ruler and second extension ruler are separated from the angle ruler, thus making it convenient for workers to use.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] like Figure 1-7 As shown, this embodiment proposes a portable measuring ruler for engineering management, including an angle ruler 1. A storage groove 2 is formed on the side wall of the angle ruler 1. An isolation block 3 is fixedly connected to the inner wall of the storage groove 2. A ruler 4 is hinged to one end inside the storage groove 2. A cavity 5 is formed on the side wall of the ruler 4. A fixing plate 6 is fixedly connected to the inner wall of the cavity 5. A sliding rod 7 is slidably connected inside the fixing plate 6. A stop block 8 is fixedly connected to the end of the sliding rod 7 away from the fixing plate 6. A spring 9 is sleeved on the outside of the sliding rod 7. A hemispherical block 15 is fixedly connected to the side wall of the isolation block 3 near the ruler 4. A hemispherical groove 16 is formed on the side wall of the stop block 8. The two ends of the spring 9... The ruler 4 is fixedly connected to the fixing plate 6 and the abutment block 8 respectively. After using the ruler 4, the user can press the abutment block 8 so that the side wall of the abutment block 8 fits against one end of the ruler 4. At this time, the spring 9 contracts. Then the worker rotates the ruler 4 so that the ruler 4 enters the storage groove 2. Then the abutment block 8 is released. The elastic force of the spring 9 will make the side wall of the abutment block 8 firmly press against the isolation block 3, thereby preventing the ruler 4 from leaving the storage groove 2 when using the angle ruler 1. When the abutment block 8 presses against the isolation block 3, if there is a large shaking, the abutment block 8 may slightly separate from the isolation block 3. At this time, the cooperation of the hemispherical groove 16 and the hemispherical block 15 can prevent the abutment block 8 from accidentally separating from the isolation block 3.

[0034] like Figure 6 and Figure 7As shown, a first extension ruler 10 is provided inside the storage slot 2 on the side away from the ruler 4. A second extension ruler 11 is hinged to one end of the first extension ruler 10. A first sliding plate 12 and a second sliding plate 13 are fixedly connected to the side walls of the first extension ruler 10 and the second extension ruler 11, respectively. A convex groove 14 is provided on the side wall of the storage slot 2. The shapes of the first sliding plate 12 and the second sliding plate 13 are two oppositely arranged "L" shapes. When it is necessary to measure a narrow area, the worker can press the first extension ruler 10 and the second extension ruler 11 with their fingers and move them to the side away from the isolation block 3. At this time, the first extension ruler 10, the second extension ruler 11, the first sliding plate 12 and the second sliding plate 13 will move to the outside of the storage slot 2 and the convex groove 14. Then the second extension ruler 11 can be rotated, and the second extension ruler 11 and the first extension ruler 10 are combined to form a new long ruler, which is convenient for the worker to use.

[0035] like Figure 1 As shown, a fixing rod 17 is fixedly connected to one end of the storage slot 2 away from the ruler 4. A coil spring 18 is sleeved on the outside of the fixing rod 17. A baffle 19 is fixedly connected to the top of the coil spring 18. The bottom end of the coil spring 18 is fixedly connected to the bottom of the storage slot 2. When in use, the coil spring 18 and the baffle 19 can block one end of the first extension ruler 10 to prevent the first extension ruler 10 and the second extension ruler 11 from directly detaching from the storage slot 2.

[0036] like Figure 1 As shown, a handle 20 is fixedly connected inside the angle ruler 1, and a level 21 is fixedly connected to the top of the handle 20. When in use, the level 21 can measure the flatness of the surface of the object being measured, increasing the versatility of the device.

[0037] like Figure 5 As shown, a nail groove 22 is provided on the side wall of the abutment block 8. When the ruler 4 is needed, the fingernail can be inserted into the nail groove 22, which makes it easier to move the abutment block 8.

[0038] like Figure 5 and Figure 6 As shown, the angle ruler 1, the straight ruler 4, the first extension ruler 10 and the second extension ruler 11 are all made of acrylic. Acrylic has excellent optical properties and durability. Acrylic is stronger than traditional plastic rulers while maintaining its lightweight characteristics.

[0039] Specifically, when using the portable measuring ruler in this project: the angle ruler 1 can measure the angle of the object being measured; the level 21 can measure the flatness of the surface of the object being measured; if the length of the object needs to be measured, a fingernail can be inserted into the nail groove 22, and then the stop block 8 can be moved towards the ruler 4 until the hemispherical groove 16 disengages from the hemispherical block 15. At this point, the ruler 4 can be rotated out for measurement. After using the ruler 4, the user can press the stop block 8 so that the side wall of the stop block 8 fits against one end of the ruler 4. At this point, the spring 9 contracts. Then, the worker rotates the ruler 4 so that the ruler 4 enters the storage groove 2. Then, the stop block 8 is released, and the elastic force of the spring 9 will make the side wall of the stop block 8 firmly press against the isolation block 3. When it is necessary to measure in a narrow space, the worker can press the first extension ruler 10 and the second extension ruler 11 with their fingers and move them away from the isolation block 3. The first extension ruler 10, the second extension ruler 11, the first sliding plate 12, and the second sliding plate 13 will first contact the baffle 19. Then the baffle 19 will open. When the first extension ruler 10, the second extension ruler 11, the first sliding plate 12, and the second sliding plate 13 move to the outside of the storage groove 2 and the convex groove 14, the coil spring 18 will drive the baffle 19 to return to its original position. Then the second extension ruler 11 can be rotated. The second extension ruler 11 and the first extension ruler 10 will be combined to form a new long ruler for the convenience of workers. When storing the first extension ruler 10 and the second extension ruler 11, rotate the second extension ruler 11 so that it is located below the first extension ruler 10. Then manually rotate the baffle 19 to open the baffle 19. Then align the first sliding plate 12 and the second sliding plate 13 with the convex groove 14. Then move the first extension ruler 10 and the second extension ruler 11 until the first extension ruler 10 and the second extension ruler 11 are completely inside the storage groove 2, thus completing the storage.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
