Description

Technical Field

[0001] The utility model relates to the technical field of an anti-mistaken-closing bracket, in particular to an anti-mistaken-closing bracket for a meter box door. Background Art

[0002] Meter boxes include electric meter boxes, water meter boxes, some large cable branch boxes, low-voltage distribution boxes, etc. Electric meter boxes and water meter boxes are commonly used civil infrastructure equipment and facilities, and are widely used in civil infrastructure construction in towns, large, medium and small cities. When installing or maintaining electrical components in the meter box, the staff needs to reach into the meter box.

[0003] At present, the door of the meter box lacks a supporting structure. When the worker is working on the meter box, the door of the outdoor meter box is easily closed by mistake. For example, if the wind blows the door or other factors cause the door to be closed, the mistakenly closed door may easily cause harm to the workers, causing collision or pinching injuries to the workers, and affecting the installation, maintenance or inspection of electrical components in the meter box. Utility Model Content

[0004] The purpose of the utility model is to provide a meter box door anti-misclosing bracket, which has the advantages of supporting the meter box door, preventing the door from being accidentally closed, and facilitating the installation, maintenance and repair of the meter box by the staff, thus solving the problems raised by the above-mentioned background technology.

[0006] The first telescopic mechanism and the second telescopic mechanism both include a sleeve rod and a threaded rod. The sleeve rod is rotatably mounted on the side end of the first mounting plate. A threaded hole is provided at the end of the sleeve rod. The threaded rod is rotatably mounted in the threaded hole. A positioning plate is installed at the end of the threaded rod. A second mounting plate is symmetrically installed at the side end of the positioning plate. A rotating shaft is rotatably mounted between the second mounting plates. A connecting rod is installed on the rotating shaft. An electromagnet is installed at the end of the connecting rod.

[0007] When using the meter box door anti-misclosing bracket of the utility model,

[0008] After the meter box door is opened, the positions of the two electromagnets are adjusted according to the opening angle of the door. The threaded rod can be extended or shortened by manually rotating the sleeve rod, so that the positions of the two electromagnets can be adjusted. The electromagnets are powered by batteries, and the metal can be adsorbed through the operation of the electromagnets. The electromagnets at the end of the second telescopic mechanism are adsorbed to the inner wall of the meter box. Then, the angle of the electromagnet at the end of the first telescopic mechanism is manually adjusted, and the electromagnet at the end of the first telescopic mechanism is adsorbed to the inner wall of the door, so that the door of the meter box can be supported, and the meter box door can be prevented from being closed by mistake.

[0009] Preferably, a battery is provided in the device box, and the battery is electrically connected to the electromagnet. The battery is provided to supply power to the electromagnet.

[0010] Preferably, a positioning hole is provided at the end of the sleeve rod outside the threaded hole, and a total of four positioning holes are arranged in an array about the sleeve rod. The positioning hole is used to accommodate the positioning rod, and when the threaded rod is extended or retracted, the positioning rod will be located in the positioning hole for extension or retraction.

[0011] Preferably, the side ends of the positioning plates are provided with positioning rods distributed in an array about the threaded rods, and the ends of the positioning rods are located in the positioning holes. The positioning holes and positioning rods can limit the threaded rods, so that when the sleeve rod rotates, the threaded rods can only perform telescopic movements, which can prevent the threaded rods from rotating and enable the threaded rods to perform telescopic adjustments normally.

[0012] Preferably, the first fixing rod and the second fixing rod are symmetrically distributed with respect to the device box.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] After the meter box door is opened, the electromagnet can adsorb metal through the operation of the electromagnet, and the electromagnet at the end of the second telescopic mechanism is adsorbed to the inner wall of the meter box. Then, the angle of the electromagnet at the end of the first telescopic mechanism is manually adjusted, and the electromagnet at the end of the first telescopic mechanism is adsorbed to the inner wall of the door, so that the door of the meter box can be supported. When the wind blows the door or an external force hits the door, the utility model can support the door and prevent the meter box door from closing, so that the door cannot cause harm to the working staff.
