Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary tools for the installation of power equipment, and particularly relates to a portable fixing device for a metering box door, which is applicable to on-site operation scenarios such as the installation and maintenance of power equipment, and is particularly suitable for the stable fixing of the box door in complex environments such as strong winds, interference from obstacles, or tilting of the box body. Background Art

[0002] Taking the power marketing profession as an example, at present, the on-site operations in the marketing profession are mostly the installation and disassembly of electricity meters in metering boxes. During the installation and disassembly process, it is necessary to fully open the box door of the metering box to carry out the work. However, due to the complex and diverse on-site environments, there are external factors such as strong winds, obstacles, and tilting of the box body due to gravity, and the box door will swing uncontrollably or suddenly close, which is likely to cause object hitting injuries and impact electric shock accidents, threatening the personal safety of the operators. Similarly, the same is true for other work scenarios that require opening the box for operation. After consulting relevant materials, it is found that there is no precedent for such a device in the current power industry. Therefore, we urgently need to invent an effective auxiliary device that can stably and reliably fix the box door without manual intervention and supervision, ensuring the safe and smooth progress of on-site operations for the staff.

[0003] In on-site operations in the power industry, such as the installation and disassembly of electricity meters in metering boxes, operators need to fully open the box door before they can operate. However, affected by environmental factors such as strong winds, tilting of the box body, or interference from obstacles, the box door is prone to uncontrolled swinging or sudden closing, resulting in object hitting injuries or impact electric shock accidents, seriously threatening the safety of the operators.

[0004] In the prior art, it usually relies on manual fixation or temporary tool support, which has defects such as poor stability, cumbersome operation, and low versatility. After retrieval, devices such as existing door and window limiters cannot adapt to the diverse sizes and complex working conditions of power box doors. Therefore, there is an urgent need for a box door fixing device that combines portability, quick disassembly and assembly capabilities, and high versatility to improve operation safety and efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a portable fixing device for a metering box door, which solves the problems of unstable box door fixing, heavy device, and poor adaptability in the prior art through structural optimization design, realizes quick installation, stable support, and wide compatibility, and ensures the safety of the operators.

[0006] A portable fixing device for a metering box door, characterized in that in the portable fixing device for a metering box door, the main support rod has a length ≤ 22 cm after folding and a total weight ≤ 650 g; the double-ended T-shaped powerful clamp has a maximum opening width of 31 mm, and the clamping part is provided with screw holes at multiple positions; the magic bearing connects the main support rod and the powerful clamp, supports 360° adjustment and is equipped with a quick wrench locking mechanism;

[0007] Both ends of the main support rod are connected to the adapter through the combination of Magic Bearing 1 and Magic Bearing 2, so that the fixing device of the portable metering box door can be unfolded and the angle can be adjusted. The T-shaped strong clamp is connected to the adapter.

[0008] The main support rod is a three-section two-axis structure, with a maximum unfolded length of 50 cm and a load-bearing capacity of ≥ 2 kg.

[0009] The main support rod is a three-section two-axis structure. Specifically, the pea pod is the axis, and there are two in total. One support rod and two strong clamps are equivalent to three sections of the structure.

[0010] A 1 / 4 nut is provided at the side end of the magic bearing, which matches the screw hole of the strong clamp to achieve multi-angle fixation.

[0011] The inner lining of the T-shaped strong clamp is a non-slip rubber pad, the clamping surface is a serrated structure, and the load-bearing capacity is ≥ 4 kg.

[0012] The surface of the main support rod is treated with hard anodized insulation to adapt to the complex outdoor environment.

[0013] Folding three-section two-axis structure: The main support rod is made of 6061T6 aluminum alloy, with an unfolded length of 30 to 60 cm, and ≤ 22 cm after folding and storage;

[0014] Universal adjustment mechanism: Both ends are connected through magic bearings, specifically a pea pod-shaped structure, supporting 360° azimuth adjustment. The shaft body is equipped with a quick wrench to lock the angle, and the deformation rate < 0.089 under a pressure of 50 N;

[0015] T-shaped strong clamp: The opening width ≤ 30 mm, the clamping surface is a serrated structure, the inner lining is a non-slip rubber pad, the load-bearing capacity is ≥ 4 kg, and it is suitable for metering boxes of any size with a box door thickness within 3 cm;

[0016] Standardized interface: A 1 / 4 nut is provided at the side end of the connecting shaft body, which matches the screw holes at multiple positions of the strong clamp and supports quick disassembly and assembly.

[0017] The device is made of an aluminum alloy frame structure, which has strong stress resistance and corrosion resistance. The main body of the device is divided into a three-section two-axis type, with the main support rod in the middle and multi-port strong clamps at both ends. The total weight of the device is less than 1000 g, the maximum unfolded length is 60 cm, the actual use length is 30 - 50 cm, and the minimum after folding and storage can reach 22 cm, and it can be stored in any tool bag. The main support rod and the strong clamp are connected by a universal shaft body, and the azimuth can be adjusted 360 degrees; there is a quick wrench at the upper end of the shaft body, and the shaft body is tightened and fixed by adjusting the wrench; the side of the connecting shaft body is a 1 / 4 nut, which can correspond to the screws at multiple positions on the strong clamp and can be flexibly converted to increase the clamping type. The double-end multi-port strong clamp has a maximum opening of 31 mm and can match and grab power box screens and cabinet doors of different specifications. The disassembly and assembly test can be completed by a single person within 30 seconds for each time.

[0020] Quick disassembly and assembly: Single-person operation can complete installation or disassembly within ≤ 30 seconds;

[0021] Universal adaptability: By adjusting the angle of the universal shaft and the position of the powerful clamp, it is compatible with more than 95% of the existing power box doors such as single-phase single-meter positions, single-phase multi-meter positions, three-phase single-meter positions, and three-phase multi-meter positions;

[0022] Corrosion resistance: The aluminum alloy material is treated by anodic oxidation to adapt to the complex outdoor environment.

[0023] This device has good mechanical strength, can withstand a positive stress of more than 50 N, and the main support rod can bear a weight of more than 2 kg. Since most on-site operations are characterized by "small, scattered, and fragmented", this device needs to have the functions of being easy to carry, quickly disassembled and assembled, so as to facilitate on-site operators to carry and use through tool kits, and avoid the device being too large in volume, too heavy in weight, and cumbersome in operation, which becomes a burden for actual users. At the same time, this device needs to match the installation conditions of the vast majority of existing power box doors, and meet the actual applications of various specifications of boxes in the current power box design specifications, improving the versatility of the device, that is, one device can solve all on-site problems.

[0024] Advantages of the invention:

[0025] 1. Improved safety: Through rigid support and multi-directional adjustment functions, it effectively prevents the accidental closing or swinging of the box door, avoiding the risks of object hitting and electric shock;

[0026] 2. Optimized operation efficiency: The folding design reduces the storage volume, and the quick-disassembly structure reduces the non-operation time;

[0027] 3. Portability and compatibility: The lightweight structure is convenient for carrying through tool kits and adapts to various box specifications;

[0028] 4. Social benefits: Reduce the incidence of safety accidents and ensure the high-quality implementation of power projects.
