Description

Electric control box

Technical Field

The utility model belongs to the technical field of electric control equipment, and relates to an electric control box.

Background

The electric cabinet is a very common control device in life, and generally comprises a shell and various control components inside the shell, and the electric cabinet can normally operate through various component control equipment inside the shell after being electrified.

The electric cabinet is widely applied, such as: industrial equipment, power installations, vehicles and the like, so that extremely high requirements are required for the sealing performance of components inside the housing; the electric cabinet shell in the prior art generally comprises a box cover and a shell, wherein all components are sequentially arranged in the shell through an assembler, and then the box cover is screwed on the shell through a fastening piece, so that an opening of the shell is sealed through the box cover; and in order to ensure the sealing performance, a sealing ring is arranged between the box cover and the shell, and the gap between the box cover and the shell is sealed and blocked by the sealing ring.

However, in the assembling process, the sealing ring can be affected by the twisting force of the fastening piece and the subsequent sealing ring is affected by expansion with heat and contraction with cold, and the gap between the shell and the box cover, which is originally blocked by the sealing ring, can be exposed again, so that dust and water can possibly penetrate into the shell from the gap to corrode each component.

Disclosure of Invention

The utility model aims to solve the problems in the prior art, and provides a mask, which aims to solve the technical problems that: how to improve the sealing effect of the electric cabinet.

The purpose of the utility model can be realized by the following technical scheme: the utility model provides an electric cabinet, includes casing and case lid, the casing with be equipped with between the case lid and be annular sealing washer, its characterized in that, the ring channel has been seted up on the case lid, just the embedded groove has been seted up along self hoop to the open end of the housing, the sealing washer inlays to be established in the ring channel, and work as the case lid passes through the fastener spiro union to be fixed when compressing tightly downwards on the casing, one side that the sealing washer is close to the casing can imbed the embedded groove.

The electric cabinet comprises a shell and a cabinet cover, wherein the cabinet cover is detachably arranged on the shell through a fastener, an annular sealing ring is arranged between the shell and the cabinet cover, an annular groove is formed in the cabinet cover, before assembly, the sealing ring can be embedded in the annular groove, so that the sealing ring is guaranteed to be limited in the subsequent assembly process, the cabinet cover is prevented from being twisted due to the locking force of the fastener in the fixing process, and further the gap between the cabinet cover and the shell is prevented from being exposed, an embedded groove is formed in the opening end of the shell along the annular direction of the shell, when an assembler assembles the cabinet cover on the shell (particularly in the process of inwards screwing the fastener), the sealing ring made of a flexible material can deform by the pressure generated in the process of screwing the fastener, so that one side, close to the shell, of the sealing ring is embedded into the embedded groove, and the sealing ring with the originally strip-shaped cross section is deformed into a curved shape under the state, therefore, the contact area between the two sides of the sealing ring and the box cover and between the two sides of the sealing ring and the shell are increased under the condition of the same stress, and the sealing performance between the box cover and the shell is further ensured.

In the electric cabinet, the bottom wall in the embedded groove is arched along the circumferential direction of the shell to form an annular bulge.

Form annular protrusion along casing circumference hunch-up on the diapire in the embedded groove, annular protrusion can separate the embedded groove along the casing hoop for the embedded groove is located the inward flange and the outward flange of casing open end respectively, makes from this in the equipment process, the inward flange and the outward flange of sealing washer inlay respectively and establish in one of them inslot, makes the transversal V-arrangement of personally submitting of sealing washer, thereby has increased the area of contact of sealing washer both sides and case lid, casing, and then has guaranteed the leakproofness between case lid and the casing.

In the electric cabinet, the annular groove is formed in the circumferential edge of the bottom of the cabinet cover.
