Description

Wiring storehouse and dc-to-ac converter

Technical Field

The utility model relates to a photovoltaic equipment technical field especially relates to a wiring storehouse and dc-to-ac converter.

Background

The inverter is used as an outdoor use product, and a cabin door of the wiring cabin needs to be opened for operation or maintenance. The bin door of the wire connection bin commonly used in the market at present has the following two structures:

(1) a single door panel structure; the staff need take off the door after opening the door, puts aside the dc-to-ac converter, just can operate, and the advantage of this structure is simple structure, practices thrift the cost, but user operation is more troublesome.

(2) A hinge is added on the door plate; the advantage of this structure is that maintenance operation is convenient, but the hinge cost is higher, and to the product of outdoor use, need consider waterproof problem when the installation hinge, its cost has increased again to a certain extent.

Thus, a solution is urgently needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to the above-mentioned problem, provide a wiring storehouse and dc-to-ac converter, it has simple structure, equipment convenience, with low costs, long service life's characteristics.

The utility model aims at realizing through the following technical scheme:

the utility model provides a wiring bin, includes the storehouse body, the front end of the storehouse body is provided with the opening, just lie in on the storehouse body the opening part is provided with the door, left upper and lower both ends in the storehouse body all through rotating assembly with the door links to each other so that the door can for the storehouse body rotates, rotating assembly is including pressing rivet nut, shaft shoulder screw, pressing rivet nut is fixed in on the storehouse body, the shaft shoulder screw includes the pin fin on upper portion, the polished rod of middle department and the screw rod of lower part, be provided with the connecting plate on the door, it has the connecting hole to open on the connecting plate, the aperture of connecting hole is less than the external diameter of pin fin, just the aperture of connecting hole is greater than the external diameter of polished rod, the lower extreme of shaft shoulder screw passes behind the connecting hole with pressing nut threaded connection.

As an optimized scheme of the utility model, the connecting hole is oval hole the door is in under the closed condition, the connecting hole is arranged along the fore-and-aft direction.

As a preferred scheme of the utility model, the pin fin, the polished rod, the screw rod structure as an organic whole.

As an optimized proposal of the utility model, the bin body is provided with an extension board, the pressure riveting nut is fixed on the extension board by compression.

An inverter comprising a wiring compartment as described above.

The beneficial effects of the utility model are that, above-mentioned wiring storehouse has simple structure, the convenient characteristics of equipment, and it can not bring waterproof problem for hinge structure, the intangible cost reduction to have long service life's characteristics.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings. It is to be understood that the embodiments described herein are merely illustrative of the present invention and are not limiting thereof.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a wire connecting bin; figure 2 is an enlarged view of one of the wiring silos shown in figure 1 at a.

In this embodiment, a wiring cabin comprises a cabin body 1, an opening is arranged at the front end of the cabin body 1, and a bin door 2 is arranged at the opening of the bin body 1, the upper end and the lower end of the left side of the bin body 1 are both connected with the bin door 2 through a rotating assembly so that the bin door 2 can rotate relative to the bin body 1, the rotating component comprises a pressure riveting nut 3 and a shaft shoulder screw 4, the pressure riveting nut 3 is fixed on the bin body 1, the shaft shoulder screw 4 comprises an upper nail head, a middle polished rod and a lower screw rod, the bin gate 2 is provided with a connecting plate, the connecting plate is provided with a connecting hole 5, the aperture of the connecting hole 5 is smaller than the outer diameter of the nail head, the aperture of the connecting hole 5 is larger than the outer diameter of the polished rod, and the lower end of the shaft shoulder screw 4 penetrates through the connecting hole 5 and then is in threaded connection with the pressure riveting nut 3.

Specifically, in this embodiment, the connection hole 5 is a kidney-round hole, and when the bin door 2 is in a closed state, the connection hole 5 is arranged in the front-rear direction; through adopting this kind of structural design for door 2 rotates the in-process, and the polished rod can slide in connecting hole 5, thereby guarantees that door 2 rotates the in-process and can not take place to interfere with storehouse body 1.

In order to facilitate production and manufacture, in the embodiment, the nail head, the polish rod and the screw rod are of an integrated structure.

Specifically, in this embodiment, a support plate 6 is disposed on the bin body 1, the support plate 6 and the bin body 1 are of an integral structure, and the pressure riveting nut 3 is fixed on the support plate 6 in a compression joint manner.

Above-mentioned wiring storehouse need not to install the hinge, and can realize door 2's rotation function, has simple structure, the convenient characteristics of equipment, and it for hinge structure, can not bring waterproof problem, the intangible cost that has reduced to have long service life's characteristics.

The embodiment also discloses an inverter which comprises the wiring cabin.

The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims.
