Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a power distribution box to solve the problem that the existing power distribution box lacks a top structure that is both rainproof and heat-dissipating and breathable. Due to the principle of hot air rising, when in use, The temperature at the upper end is higher than the middle position inside. If the hot air flow at the top cannot be dissipated in time, it will easily affect the work of the original components inside the distribution box, and the existing distribution box lacks an auxiliary structure that is convenient for the staff to carry out wiring. Since the distribution box is usually installed At the upper end of the utility pole, when wiring, the staff need to climb to the high altitude for one-handed operation. The traditional power distribution box is not conducive to the one-handed operation of the staff. When wiring, the staff needs to reach out to the bottom of the distribution box. Inside, it is extremely troublesome to operate

Embodiment

[0059] as attached figure 1 to the attached Figure 8 shown:

[0060] The present invention provides an electric power distribution box, comprising: an external mechanism 1; a splicing mechanism 2 is provided at the bottom of the external mechanism 1; The upper end is provided with the closing mechanism 4, and the top of the support rod 202 is mounted on the heat sink 501; the middle position of the front end of the external mechanism 1 is provided with the mounting mechanism 3, and the moving plate 301 of the mounting mechanism 3 is mounted on the main board 101 through two sets of tension springs; The fixing rod 402 of the closing mechanism 4 is fixedly installed on both sides of the rear end of the bottom plate 201 , the upper end of the fixing rod 402 is connected with the heat dissipation plate 501 of the heat dissipation mechanism 5 , and an elastic member is provided between the movable plate 401 of the closing mechanism 4 and the main board 101 . ; The heat dissipati...

Embodiment approach

[0064] As an embodiment of the present application, the closing mechanism 4 includes: a movable plate 401, which is a C-shaped plate-like structure, the front end of the movable plate 401 is provided with a handle, the rear end of the movable plate 401 is provided with a circular groove, and the movable plate 401 There is a circular through hole inside the rear side; the fixing rod 402 is a cylindrical structure, and the two sides of the fixing rod 402 are provided with cylindrical limit blocks, and a movable plate 401 is rotatably installed in the middle of the limit block. The circuit inside the device is protected, and the movable plate 301 is pushed to move in the open state, and the fixed rod 402 is provided to facilitate the installation of the movable plate 401 and enable the movable plate 401 to rotate around the axis.

[0065] As another implementation of the embodiment of the present invention, the elastic member between the movable plate 401 and the main board 101 ca...

Abstract

The invention provides a power distribution box, relates to the technical field of power distribution boxes, and aims to solve the problems that an existing power distribution box lacks an auxiliary structure facilitating wiring of a worker, the worker needs to climb to a high altitude for single-hand operation during wiring due to the fact that the power distribution box is usually installed at the upper end of a telegraph pole, a traditional power distribution box is not beneficial to single-hand operation of the worker who needs to stretch a hand into the innermost part of the power distribution box during wiring, and the operation is very troublesome. The power distribution box comprises an external mechanism; and a splicing mechanism is arranged at the bottom of the external mechanism. When wiring work is carried out, an operator can unlock movable plates to enable the movable plates to be automatically bounced off towards the two sides, the movable plates rotate around the axis of a fixed rod after being jacked up by elastic pieces on the rear sides, the rear ends of the movable plates make contact with trapezoidal grooves of a moving plate through rotation, and along with continuous increase of the opening angle of the two movable plates, the movable plates jacks up the moving plate forwards, so that the moving plate extends forwards, and a worker can perform wiring conveniently.

Description

technical field [0001] The invention belongs to the technical field of distribution boxes, and more specifically relates to a power distribution box. Background technique [0002] With the development of the economy, urban and rural power grids have higher and higher requirements for the development of public distribution boxes. Distribution boxes are the basic guarantee for residents to use electricity. Use on the top of outdoor utility poles to avoid accidental touch by pedestrians and vandalism. [0003] For example, the application number: CN202011088055.4 relates to a power distribution box, including a base, a cabinet, an antenna device and a control panel. The base is provided with a shaft hole, a connecting arm, a first motor and a shaft seat, and the shaft hole is opened in the base. In the middle of the top, the connecting arm is welded on the upper left side of the inside of the base. The first motor is installed and fixed on the left side of the inside of the ba...
