Abstract

The utility model discloses a public transformation box with hoisting hooks. The public transformation box comprises a box top (1) and a box body (2); the box top (1) is mounted on the box body (2); the hoisting hooks (3) are respectively mounted on two opposite sidewalls of the box body (2); each hoisting hook (3) comprises a hook handle (3.1) and a hook body (3.2), and the hook body (3.2) is connected with the hook handle (3.1); the hook body (3.2) is integrated with the hook handle (3.1); and multiple projections (3.3) are uniformly distributed on the inner ring of the hook body (3.2), protruded along the radial direction of the hook body (3.2) and integrated with the hook body (3.2). The hoisting hooks of the public transformation box have the antiskid effect.

Description

Public affairs with Lift hook become case

Technical field

The utility model relates to the public case that becomes, and relates to or rather a kind of public affairs with Lift hook and becomes case.

Background technology

There are two kinds of service message forms in resident's service message: a kind of is that public change, another kind are special changes.So-called public become refer to on-site circuit, transformer, to the ammeter of each household all by power supply administration install, safeguard, the abbreviation of management.The public case that becomes generally is arranged on the parts such as outdoor, user installation and protection transformer.The public case that becomes comprises case top and casing, and described case top is arranged on described casing.In order to lift conveniently, on two relative sidewalls of the casing of the public affairs of prior art change case, be equipped with Lift hook.The Lift hook of prior art comprises the neck of hook and coupler body, and described coupler body is connected on the described neck of hook, and described coupler body and the neck of hook are one-body molded.The inner ring of the coupler body of prior art is smooth, in the process of lifting, easily skids and causes security incident.

The utility model content

Technical problem to be solved in the utility model is that the public affairs with Lift hook that provide a kind of Lift hook to have skidproof effect become case.

For solving the problems of the technologies described above, the utility model provides a kind of public affairs with Lift hook to become case, comprises case top and casing; Described case top is arranged on described casing; Be equipped with Lift hook on two relative sidewalls of described casing; Described Lift hook comprises the neck of hook and coupler body, and described coupler body is connected on the described neck of hook; Described coupler body and the neck of hook are one-body molded; The inner ring of described coupler body is evenly distributed with a plurality of projections along the coupler body radial projection, and described projection and described coupler body are one-body molded.

After adopting above structure, the inner ring that the public affairs with Lift hook of the present utility model become the coupler body of case is provided with a plurality of projections, in the process of using, can increase the frictional force between suspension hook and Lift hook inner ring like this, prevents that suspension hook from skidding, and therefore avoids occurring security incident.

As a kind of improvement of the present utility model, described projection is hemisphere.This kind of structure is optimum implementation.

As another kind of improvement the of the present utility model, described coupler body is provided with a plurality of antislip rings; Described antislip ring radially arranges and is arranged in equably on described coupler body along coupler body.After adopting this kind of structure, described antislip ring can increase frictional force more, so skidproof effect is better.

Also have a kind of improvement as of the present utility model, be equipped with 11 antislip rings on the coupler body of each Lift hook.This kind is designed to optimum implementation.
