Abstract
The utility model provides a little three -box of sealed with silicone rubber, including the box, the bottom half is equipped with the installation foot, and the box passes through hinge and casing cover connection, and is sealed through the sealed with silicone rubber strip between box and the case lid, on the case mouth of box along inwards bend and with the laminating of box inner wall, the department of bending forms the circular arc, circular arc department with the sealed with silicone rubber strip is crossed and is won the cooperation. The device provided by the utility model the case mouth flattens the technical processing through two bending, and whole case mouth is once bent and is flattened the shaping. Case mouth edge is reserved when flattening, ensures that the edge forms the circular arc. Once bending and flattening fashioned case mouth processing degree of difficulty greatly reduced, take the circular arc to flatten fashioned case mouth, not only increased the rigidity of case mouth, the arc surface is also impressed the sealed with silicone rubber strip easily and sealed effectual, still can not lacerate the sealed with silicone rubber strip.
Description
Technical field
The utility model relates in a kind of power supply industry electrical assemblies switchgear equipment little three casees used, and particularly relates to a kind of little three casees being undertaken sealing by silastic sealing strip.
Background technology
Electrically mainly comprise headstock, lighting case, batch meter etc. little three casees.Control cabinet, socket box belong to headstock classification, and user kit belongs to lighting case classification, and ammeter box belongs to batch meter classification.This kind of nonstandard all small box are all referred to as little three casees.
At present, require in the product of little three casees of high switchgear assembly in useful life, usually adopt silicon rubber to make seal, as shown in Figure 1, casing 1 is connected with case lid 4 by hinge 2, is sealed between casing 1 and case lid 4 by silastic sealing strip 3.Silicon rubber has feature that is high temperature resistant, long service life, but silastic sealing strip is close relative to its material of sealing strip of other materials and hard, therefore, the case mouth of band gradient made by usual casing 1, be convenient to the insertion silastic sealing strip 3 that case mouth edge can be more deep, play sealing effectiveness effectively.But this structure defect specific as follows:
1) the case oral area indent of casing forms the case mouth of band gradient, and it is complicated that this structure adds man-hour processing step, needs special equipment and special grinding apparatus, and cost is higher and waste time and energy;
2) silastic sealing strip directly inserts from the edge of case oralia material, and the corner angle that case oralia material is sharp easily cut silastic sealing strip.
Utility model content
The technical problems to be solved in the utility model is to provide a kind ofly processes convenient welding, good sealing effect and can not cut little three casees of silastic sealing strip.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide little three casees of a kind of silicone rubber seal, comprise casing, bottom half is provided with installation foot, casing is connected with case lid by hinge, is sealed between casing and case lid by silastic sealing strip, it is characterized in that: the case mouth of described casing is fitted along inside bending with cabinet wall, bending part forms circular arc, and circular arc place and described silastic sealing strip are crossed to win and coordinated.
Preferably, along being square waveform on the case mouth of described casing, after bending, square waveform place and cabinet wall are fitted.
The device case mouth that the utility model provides is by the processing of double-bending flattening technology, and the bending of whole case mouth is flattened shaping.During flattening, case mouth edge reserves, and guarantees that edge forms circular arc.A bending is flattened shaping case mouth difficulty of processing and is greatly reduced, and band circular arc flattens shaping case mouth, not only adds the rigidity of case mouth, and arc surface is also easily pressed into silastic sealing strip and good sealing effect, also can not cut silastic sealing strip.

Embodiment
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The little three casees cutaway views of silicone rubber seal that Fig. 2 provides for the utility model, described silicone rubber seal is little comprises casing 1 for three casees, installation foot 7 is housed bottom casing 1, casing 1 is connected with case lid 4 by hinge 2, sealed by silastic sealing strip 3 between casing 1 and case lid 4, casing 1 and case lid 4 are also locked by clamping screw 5 and locking nut 6.Composition graphs 3, the case mouth of casing 1 is fitted along inside bending with cabinet wall, and bending part forms circular arc.
Composition graphs 4, the case mouth of casing 1 flattens technology processing by double-bending, and the bending of whole case mouth is flattened shaping.During flattening, case mouth edge reserves, and guarantees that edge forms circular arc.A bending is flattened shaping case mouth difficulty of processing and is greatly reduced, and band circular arc flattens shaping case mouth, not only adds the rigidity of case mouth, and arc surface is also easily pressed into silastic sealing strip 3 and good sealing effect, also can not cut silastic sealing strip.
Composition graphs 5 and Fig. 6, edge on the case mouth of casing 1 is designed to square waveform, and after bending, square waveform place and cabinet wall are fitted, and square wave-shaped configuration contributes to realizing a bending better and flattens shaping, makes on case mouth along fitting tightr with cabinet wall.
Add man-hour, the four sides side plate of casing 1 is on one block of plate, and the case mouth of flattening is on the top of respective side plate.First, along going out breach on the case mouth of casing, form square wave-shaped configuration, then along the case mouth bending part of whole casing under shape is into a straight condition, carry out Integral bending flattening, during flattening, case mouth edge reserves, and guarantees that edge forms circular arc.Then, 90 degree of bendings are carried out to casing, make it form a casing casing only having a limit not link up.During welding processing, as long as the splice point both sides alignment of guard box mouth, just can realize the smooth welding of case mouth.As long as bottom half adds in the welding of block base plate, whole casing just welding completes.Silastic sealing strip 3 is pasted onto on case lid 4, as long as to control the degree of depth of case mouth press-in silastic sealing strip well just passable in the welding of hinge 2, processing welding is simple and convenient.
The little three-bin system of the silicone rubber seal of the flattening shaping box mouth that the utility model provides is done simple, and without the need to special equipment and special grinding apparatus, processing technology is good, can accomplish that volume is enough little, is applicable to the degree of protection such as nuclear power, explosion-proof, EME and requires that high occasion uses.
