Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof distribution boxes, in particular to a folded edge reinforcement structure of an explosion-proof distribution box. Background Art

[0002] Explosion-proof distribution box is a kind of distribution box with explosion-proof performance, which is widely used in many fields such as petroleum, chemical industry, coal mining, textile, printing and dyeing, etc. Its main goal is to prevent danger from occurring during the operation of electrical components and further improve operational safety. In order to increase the strength and rigidity of the box body and prevent deformation or rupture caused by external impact or vibration during use, a folding reinforcement structure of explosion-proof distribution box is proposed.

[0003] According to the search, the Chinese patent document, announcement number: CN213093653U, discloses a distribution box with a reinforced anti-impact structure, which uses a steel structure support frame built into the inner wall of the box to enhance the mechanical strength of the inner wall of the box, and the box is fixedly connected to the support seat, which is pre-buried in the ground through concrete, and the upper end of the anti-impact stabilizing seat in the support seat is sleeved and connected to the steel structure support frame, so that the anti-impact stabilizing seat and the steel structure support frame are connected as a whole, which can evenly conduct the impact force and improve the stability of the box when it is impacted. However, since the device is fixed in the base and has no effective buffer structure, it may cause the box to deform or even break when it is impacted, affecting its performance and life. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a folded edge reinforcement structure for an explosion-proof distribution box, which has the advantages of high strength, stable structure, and good buffering performance, and solves the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a folded edge reinforcement structure of an explosion-proof distribution box, comprising an outer shell, a box door is hinged on the front side of the outer shell, a handle is installed on the front side of the box door, a protective frame is fixedly installed on the top surface of the outer shell, a protective cover is fixedly installed on the outer side of the outer shell, a triangular support column, a stabilizing rod and an inner shell are fixedly installed inside the outer shell, a buffer column and a buffer pad are fixedly installed on the outer side of the inner shell, and a triangular support frame is fixedly installed inside the inner shell.

[0008] Preferably, the number of the protective sleeves is four.

[0009] Through the above technical solution, the four protective covers and the protective frame can not only effectively prevent the distribution box from being hit or rubbed during transportation and handling, but also prevent the interior from being contaminated by dust, moisture, grease and other substances; in addition, the protective cover can also serve as an additional protective layer for the outer shell to prevent it from being affected by external extreme environments such as high temperature, low temperature, high pressure, and low pressure, thereby ensuring its normal operation and extending its service life.

[0010] Preferably, the triangular support columns and the stabilizing rods are provided in plural numbers.

[0011] Through the above technical solution, multiple triangular support columns and stabilizer bars can make the installation process more convenient and quick, reduce the difficulty and workload of installation, and the triangular support columns and stabilizer bars can help the outer shell remain stable during installation and use, avoiding displacement or damage caused by vibration or other external forces, thereby effectively protecting the electrical components inside the distribution box and extending its service life.

[0012] Preferably, the buffer columns and the buffer pads are both provided in plural numbers, and the plurality of buffer columns and the plurality of buffer pads are evenly distributed on the outer surface of the inner shell.

[0013] Through the above technical solution, multiple buffer columns and buffer pads can withstand greater impact forces, thus not only helping the inner shell to remain stable during installation, but also effectively protecting the inner shell to prevent it from being impacted or rubbed during transportation and handling, thereby reducing damage to the entire device.

[0014] Preferably, a spring is fixedly installed inside the buffer column, and one end of the spring away from the buffer column is fixedly connected to a moving block.

[0015] Through the above technical solution, when the outer shell is impacted by external force, the buffer pad will first buffer part of the impact force, and then the outer shell will deform to squeeze the moving block, and the moving block will buffer the remaining part of the impact force under the action of the spring, thereby effectively improving the overall shock absorption capacity of the device.

[0016] Preferably, the number of the triangular support frames is eight.

[0017] Through the above technical solution, the eight triangular support frames can not only help the inner shell to remain stable during installation and use, avoiding displacement or damage caused by vibration or other external forces, but the triangular support frames are also easy and convenient to install, occupy less space, and provide convenience for subsequent maintenance.

[0018] Compared with the prior art, the utility model provides a folding reinforcement structure of an explosion-proof distribution box, which has the following beneficial effects:

[0020] 2. The utility model will first buffer a part of the impact force through the buffer pad, and then the outer shell will deform to squeeze the moving block, and the moving block will buffer the remaining part of the impact force under the action of the spring. Therefore, it can not only help the inner shell to remain stable during installation, but also effectively protect the inner shell to prevent it from being hit or rubbed during transportation and handling, thereby reducing the overall damage of the device; the eight triangular support frames can not only help the inner shell to remain stable during installation and use, and avoid displacement or damage caused by vibration or other external forces, but the triangular support frames are also easy and convenient to install, occupy less space, and provide convenience for later maintenance.
