Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of power engineering related tools and equipment, and more specifically, to a measurement toolbox for power engineering design. Background Technology

[0002] In power engineering design, from the initial planning and surveying to the mid-term on-site construction guidance and the later equipment commissioning and maintenance, engineers always need various measuring tools to ensure the accurate implementation of the project. Power engineering measurement covers many aspects, from the length of transmission lines and the spacing between towers, to the installation location of equipment in substations and the measurement of electrical parameters. Its accuracy directly affects the stability and safety of the power system operation.

[0003] Traditional power engineering design measurement toolboxes have gradually revealed many limitations when facing complex and ever-changing work scenarios. Common toolboxes often adopt simple box structures, which can only achieve rough storage of tools and have relatively limited functions. On the construction site, engineers often need to frequently switch between multiple tools. However, existing toolboxes lack reasonable partitioning and fixing measures. Tools are placed randomly inside the box, which is not only inconvenient to access, but also prone to collision and wear during transportation, thus shortening the service life of the tools.

[0004] In addition, traditional toolboxes are not portable enough. When engineers need to travel outdoors or to different work areas for long periods of time, heavy toolboxes that lack humanized portability design can become a considerable burden. For example, some toolboxes are only equipped with simple carrying handles, which can easily cause hand fatigue after holding them for a long time. Moreover, in construction sites with complex road conditions, it is not safe to carry a toolbox with one hand, nor is it convenient to carry other equipment at the same time. At the same time, most existing toolboxes do not fully consider the effective fixation and protection of storage spaces such as drawers. During transportation, drawers can easily slide out accidentally, causing tools to scatter and affecting work progress.

[0005] In scenarios requiring rapid access and organization of measuring tools, traditional measuring toolboxes are insufficient. Power engineering operations are often time-sensitive, such as during emergency repairs where workers need to quickly locate the necessary tools. However, the design of traditional toolboxes makes the tool-finding process time-consuming and laborious, severely impacting work efficiency. Therefore, developing a new type of measuring toolbox with good portability, a reasonable storage structure, and reliable locking function is of significant practical importance for improving the efficiency and quality of power engineering design work. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a measurement toolbox for power engineering design, which solves the problem that traditional measurement toolboxes for power engineering design in the prior art have gradually revealed many limitations when facing complex and ever-changing work scenarios. Common toolboxes mostly adopt simple box structures, which can only achieve rough storage of tools and have relatively single functions. On the construction site, engineers often need to frequently switch between multiple tools. However, existing toolboxes lack reasonable partitioning and fixing measures. Tools are placed randomly in the box, which is not only inconvenient to take out, but also easy to collide and wear each other during carrying, shortening the service life of the tools.

[0007] According to one aspect, at least one embodiment of this disclosure provides a measurement toolbox for power engineering design, comprising:

[0008] A portable case, wherein a drawer is provided on the side wall of the portable case;

[0009] A plug-in locking assembly is disposed inside the portable case.

[0010] A portable lifting assembly is disposed inside the portable case.

[0011] The plug-in locking assembly includes a plug-in cavity, which is opened on the side wall of the portable case. The drawer is inserted into the interior of the plug-in cavity. The side wall of the drawer is provided with a locking groove. A pull rod is inserted into the interior of the portable case. A portion of the pull rod is embedded in the locking groove. The upper end of the pull rod extends out of the upper surface of the portable case. The upper end of the portable case is provided with a receiving cavity, and a flip-up cover is provided on the receiving cavity.

[0012] As a further technical solution, a support strip is provided on the inner wall of the insertion cavity, and the support strip is in contact with the bottom surface of the drawer.

[0013] As a further technical solution, the portable lifting assembly includes a connecting frame, an internal pin of which is connected to a folding frame, a lifting rod is connected to the end pin of the folding frame, a locking sleeve is provided at the lower end of the lifting rod, a locking piece is provided at the upper end of the locking sleeve, a locking ring is provided on the side wall of the portable case, and the end of the locking piece is embedded in the interior of the locking ring.

[0014] As a further technical solution, the inner sidewall of the lifting rod is provided with a movable shaft, and the locking sleeve is movably fitted inside the movable shaft.

[0015] As a further technical solution, the drawer is provided with a limiting plate on its side wall, and the inner side wall of the limiting plate is provided with a groove, and the limiting plate is fitted to the portable case.

[0016] As a further technical solution, the flip cover is provided with an operating handle, which is located on the side wall of the flip cover.

[0017] As a further technical solution, the upper surface of the portable case is provided with a through hole, and one end of the pull rod is inserted into the through hole.

[0018] As a further technical solution, a stabilizing sleeve is provided on the inner side wall of the portable case, and the stabilizing sleeve is fitted onto the pull rod.

[0019] As a further technical solution, the number of drawers is several, and the multiple drawers are arranged longitudinally on the side wall of the portable case.

[0020] As a further technical solution, the flip-top cover has an L-shaped cross-section and is connected to the upper pin of the portable case.

[0021] The beneficial effects of the embodiments disclosed herein are as follows:

[0022] 1. In this disclosure, the portable lifting component of the measuring toolbox is ingeniously designed. The coordinated operation of the connecting frame, the folding frame, and the lifting rod allows the user to flexibly adjust the position of the lifting rod according to actual needs. During transportation, the folding frame is flipped out and the lifting rod is raised. It is then fixed to the locking ring on the side wall of the box by the locking sleeve and locking plate. At this time, the lifting rod becomes a comfortable and stable lifting handle, which greatly reduces the burden on the hands. Compared with traditional carrying handles, it makes it easier for engineers to move the toolbox over long distances.

[0023] 2. In this disclosure, the cooperation between the pull rod and the locking groove on the side wall of the drawer, as well as the locking of the pull rod by the flip-top cover, can ensure that the drawer will not slide out accidentally during transportation, preventing tools from being scattered and damaged. In addition, the contact between the bottom surface of the drawer and the support strip on the inner side wall of the insertion cavity not only reduces the friction when the drawer slides and reduces the risk of wear, but also buffers vibration to a certain extent, preventing tools from being damaged by collision.

[0036] like Figures 1-4 As shown, a measurement toolbox for power engineering design according to this disclosure includes:

[0037] Portable case 1, with drawers 2 provided on the side wall of portable case 1;

[0038] The plug-in locking component 3 is located inside the portable case 1;

[0039] Portable lifting component 4 is installed inside the portable case 1;

[0040] The plug-in locking assembly 3 includes a plug-in cavity 3-1, which is located on the side wall of the portable case 1. A drawer 2 is inserted into the interior of the plug-in cavity 3-1. A locking groove 3-2 is provided on the side wall of the drawer 2. A pull rod 3-3 is inserted into the interior of the portable case 1. Part of the pull rod 3-3 is embedded in the locking groove 3-2. The upper end of the pull rod 3-3 extends out of the upper surface of the portable case 1. A receiving cavity 3-4 is provided at the upper end of the portable case 1. A flip-up cover 3-5 is provided on the receiving cavity 3-4.

[0041] The portable lifting assembly 4 includes a connecting frame 4-1, with a folding frame 4-2 connected to the inside of the connecting frame 4-1 by a pin. The end of the folding frame 4-2 is connected to a lifting rod 4-3 by a pin. A locking sleeve 4-4 is provided at the lower end of the lifting rod 4-3, and a locking piece 4-5 is provided at the upper end of the locking sleeve 4-4. A locking ring 4-6 is provided on the side wall of the portable case 1, and the end of the locking piece 4-5 is embedded inside the locking ring 4-6.

[0042] In some examples, a rectangular cavity 3-1 is provided on the side wall of the portable case 1, and its size precisely matches the shape of the drawer 2 to ensure that the drawer 2 can be inserted tightly and smoothly. The inner side wall of the cavity 3-1 is polished to reduce the friction when the drawer 2 is pulled out. At the upper end of the portable case 1, a receiving cavity 3-4 is machined using a milling process. The size of the receiving cavity 3-4 is large enough to accommodate the upper part of the pull rod 3-3. The flip cover 3-5 is made of metal and has an L-shaped cross-section. One end of the flip cover 3-5 is connected to the upper end of the portable case 1 by a pin, so that the flip cover 3-5 can be freely flipped around the pin. When it is necessary to lock the drawer 2, the pull rod 3-3 is pressed down to fit into the locking groove 3-2, and then the flip cover 3-5 is closed, and the upper end of the pull rod 3-3 is housed in the receiving cavity 3-4 to prevent the pull rod 3-3 from being pulled up accidentally.

[0043] Inside the portable case 1, on both side walls, a connecting frame 4-1 is fixed by screws or welding. The connecting frame 4-1 is made of metal and its shape and size are designed to stably support the folding frame 4-2. One end of the folding frame 4-2 is connected to the connecting frame 4-1 by a pin, allowing the folding frame 4-2 to rotate freely around the pin within the connecting frame 4-1. One end of the lifting rod 4-3 is connected to the end of the folding frame 4-2 by a pin, and it can also rotate around the pin. On the inner side wall of the lifting rod 4-3, a movable shaft 4-7 is installed and fixed to the lifting rod 4-3 by welding or screws. On the upper end of the locking sleeve 4-4, a locking plate 4-5 is welded or fixed by screws. The locking piece 4-5 is made of metal, and its end is designed to be accurately embedded in the locking ring 4-6 on the side wall of the portable case 1. The locking ring 4-6 is installed on the side wall of the portable case 1 according to the position of the locking piece 4-5. The locking ring 4-6 is made of metal and is fixed to the side wall of the case by welding or screws. When it is necessary to lift the portable case 1, the folding frame 4-2 is flipped out from the connecting frame 4-1, and then the lifting rod 4-3 is rotated to make the lifting rod 4-3 vertical. Then the locking sleeve 4-4 is rotated so that the end of the locking piece 4-5 is embedded in the locking ring 4-6, thereby fixing the lifting rod 4-3 and making it convenient for the user to lift the case.

[0044] like Figures 1-4 As shown, in this embodiment, a support strip 3-6 is provided on the inner wall of the insertion cavity 3-1, and the support strip 3-6 is in contact with the bottom surface of the drawer 2.

[0045] In some examples, the support bar 3-6 is made of wear-resistant plastic or rubber, and its height and width are designed according to the weight and size of the drawer 2 to ensure that it can effectively support the drawer 2, reduce the friction between the drawer 2 and the insertion cavity 3-1, and extend the service life of the drawer 2.

[0046] For example, such as Figure 4 As shown, the inner wall of the lifting rod 4-3 is provided with a movable shaft 4-7, and the locking sleeve 4-4 is movably fitted inside the movable shaft 4-7.

[0047] In some examples, the locking sleeve 4-4 is fitted onto the movable shaft 4-7, allowing the locking sleeve 4-4 to rotate around the movable shaft 4-7.

[0048] For example, such as Figure 3 As shown, the side wall of drawer 2 is provided with a limiting plate 5, and the inner side wall of the limiting plate 5 is provided with a groove 6. The limiting plate 5 is attached to the portable case 1.

[0049] In some examples, a limiting plate 5 is fixed to the outer wall of drawer 2 by screws or welding, so that the user can pull drawer 2 with their fingers. The diameter of the limiting plate 5 is larger than the opening diameter of the insertion cavity 3-1. When drawer 2 is fully inserted into insertion cavity 3-1, the limiting plate 5 fits tightly against the outer wall of portable case 1 to prevent drawer 2 from being over-inserted.

[0050] For example, such as Figure 1 As shown, an operating handle 7 is provided on the flip cover 3-5, and the operating handle 7 is located on the side wall of the flip cover 3-5.

[0051] In some examples, an operating handle 7 is installed on the side wall of the flip cover 3-5. The operating handle 7 is made of plastic or metal to facilitate the user to open and close the flip cover 3-5.

[0052] For example, such as Figure 2 As shown, the upper surface of the portable case 1 is provided with a through hole 8, and one end of the pull rod 3-3 is inserted into the through hole 8.

[0053] In some examples, a through hole 8 is drilled on the upper surface of the portable case 1 using a drilling device. The position of the through hole 8 corresponds to the locking groove 3-2 on the drawer 2. The pull rod 3-3 is made of high-strength metal rod with a diameter that matches the through hole 8. It can move freely up and down within the through hole 8. One end of the pull rod 3-3 is inserted into the through hole 8 so that its lower end can be accurately embedded in the locking groove 3-2 on the side wall of the drawer 2, thereby locking the drawer 2.

[0054] For example, such as Figure 2 As shown, a stabilizing sleeve 9 is provided on the inner side wall of the portable case 1, and the stabilizing sleeve 9 is fitted onto the pull rod 3-3.

[0055] In some examples, the stabilizing sleeve 9 is inside the portable case 1, around the pull rod 3-3, and is fixed by glue or screws. The stabilizing sleeve 9 is made of rubber or plastic and its inner diameter matches the diameter of the pull rod 3-3. It is used to stabilize the pull rod 3-3 and prevent it from shaking during use.

[0056] For example, such as Figure 1 As shown, there are several drawers 2, and multiple drawers 2 are arranged longitudinally on the side wall of the portable case 1. The cross-section of the flip-top cover 3-5 is L-shaped, and the flip-top cover 3-5 is connected to the upper end pin of the portable case 1.

[0057] When using it, open drawer 2, hold the groove 6 on the inner side wall of the limit plate 5 with your finger, pull drawer 2 outward, and put the sorted tools into the corresponding drawer 2 in order. Note that the tools should be arranged neatly to avoid stacking or squeezing each other, which will affect the subsequent use. For example, screwdrivers can be neatly arranged on one side of drawer 2, and wrenches can be placed on the other side.

[0058] After placing all the tools inside, gently push drawer 2 to allow it to slowly slide into the insertion cavity 3-1. Once drawer 2 is fully inserted, the limiting plate 5 will fit tightly against the outer wall of the portable case 1. At this point, to prevent drawer 2 from accidentally sliding out, operate the insertion locking component 3 and press down the pull rod 3-3 located on the upper surface of the portable case 1 so that the lower end of the pull rod 3-3 is accurately embedded in the locking groove 3-2 on the side wall of drawer 2. Then, flip the flip cover 3-5 located on the receiving cavity 3-4 to receive the upper end of the pull rod 3-3 in the receiving cavity 3-4 and fasten the flip cover 3-5 to complete the locking of drawer 2.

[0059] When the toolbox needs to be moved, first open the flip cover 3-5, pull up the lever 3-3 to disengage it from the locking groove 3-2 of drawer 2, then flip the folding bracket 4-2 on the connecting frame 4-1 inside the portable case 1 around the pin, then rotate the lifting rod 4-3 connected to the pin at the end of the folding bracket 4-2 so that the lifting rod 4-3 is perpendicular to the ground, rotate the locking sleeve 4-4 on the movable shaft 4-7 on the inner side wall of the lifting rod 4-3 so that the locking plate 4- at the upper end of the locking sleeve 4-4... 5. The end is accurately embedded into the locking ring 4-6 on the side wall of the portable case 1, thereby firmly fixing the lifting rod 4-3. At this time, the lifting rod 4-3 becomes a convenient handle for gripping. Users can hold the lifting rod 4-3 with both hands to lift and carry the toolbox to the required location. During the transportation process, pay attention to keeping it stable and avoid violent shaking or collision to prevent the tools inside the case from being damaged by vibration. If long-distance transportation is required, the grip posture can be adjusted in time according to the actual situation to reduce hand fatigue.
