Description
Technical field
The invention belongs to industrial applications and rail to hand over application field, and in particular to a kind of Split type box body.
Background technique
Present Split type box body sealing structure mainly has following 2 kinds: 1, single-side sealing, sealing element are installed on panel and case
Between body, box back surface welded nut is fixed finally by fastener；2, single-side sealing, sealing element are installed on panel and cabinet
Between, box back surface welds swivel nut (screw thread is not through swivel nut), fixes finally by fastener；The first above sealing structure without
Method is solved due to welding bring problem on deformation, and due to welded nut, the substances such as water or dust can be with screw thread
Gap enters cabinet, therefore can not be applicable in the higher environment of degree of protection；Second of sealing structure is using welding swivel nut, although solution
The problem of substances such as water or dust of having determined can enter cabinet with screw thread gap, but welding bring can not be solved
Problem on deformation influences integral protection performance, therefore is also not suitable for being applicable in the higher environment of degree of protection.
In addition, there are mainly two types of seal forms for existing box sealing strips: line squeezes sealing and face squeezes sealing.Needle
To both the above seal form, strip or ribbon seal are commonly used, glue is carried by glue or sealing strip and is sticked on cabinet.This
Kind sealing strips have following 3 defects, first is that glue, which easily reacts with tank surface process layer (such as baking vanish), generates nocuousness
Gas, second is that being not easy to remove after the sealing strip long-time of cabinet, third is that replacement sealing strip process is various.
Summary of the invention
It is an object of the invention to overcome the problems, such as screw gap and the decline of welding deformation bring protective performance, one kind is provided
Split type junction box makes product can be applied to high requirement of shelter occasion, and the present invention includes can not easily to fall off close of Fast Installation
Strip of paper used for sealing, the sealing strip are pasted without glue, quick for installation, reliable, not only can be in the case where the seal request as defined in meeting
There is provided sealing reliability by dual face seals, moreover it is possible to be conveniently replaceable, only need to directly replace sealing strip, without other tools and
Auxiliary material.Which improves installation and maintenance maintenance costs, can save working hour, to reduce working service cost.
The present invention includes screw, panel, U-shaped rubber weather strip, compressing member and cabinet；The cabinet offers centre bore
One, one edge of centre bore opens up equally distributed n through-hole one, n >=6；The compressing member offers n blind hole, and blind hole is set
There is internal screw thread；N blind hole is aligned one by one with the central axis of n through-hole one.The global shape and centre bore of U-shaped rubber weather strip
One shape is consistent；The centre bore two being coaxially disposed with centre bore one is offered on the end face of U-shaped rubber weather strip, and at center
Two edge of hole opens up equally distributed n through-hole two, and n through-hole two is aligned one by one with the central axis of n through-hole one；U-shaped rubber
The side of glue sealing strip is equipped with global shape and the consistent conduit of one shape of centre bore；The both ends in U-shaped rubber weather strip section are equal
It is U-shaped.The panel face opposite with cabinet offers n through-hole three, one a pair of central axis of n through-hole three and n through-hole one
Together；The centre bore one of the conduit package cabinet of U-shaped rubber weather strip, panel compress U-shaped rubber weather strip outer end face；Compressing member is set
In in cabinet and compressing U-shaped rubber weather strip inner face；Each through-hole three, through-hole two and the through-hole one of alignment pass through one in combining
A screw；The blind hole connection corresponding with compressing member of the tail portion of each screw.
The centre bore one is circular hole, and all through-holes one are circumferential uniformly distributed along centre bore one.
The centre bore one is square hole, and through-hole one is equidistantly arranged along one length direction of centre bore, in the width direction also etc.
Away from arrangement.
The compressing member is monolithic construction.
The compressing member includes n/3 block briquetting；Every piece of briquetting offers 3 blind holes.
Several component installing ports are also provided on the panel, each component installing port edge offers array
Four through-holes four of arrangement.
The U-shaped rubber weather strip includes U-shaped rubber matrix and metal clips, and U-shaped rubber matrix wraps up metal clips；
Each through-hole two runs through U-shaped rubber matrix and metal clips；The global shape of U-shaped rubber matrix and metal clips is and center
The shape in hole one is consistent.The both ends in U-shaped rubber matrix section are U-shaped.The both ends in metal clips section are also U-shaped.
The U-shaped rubber matrix uses silicone rubber material.
The metal clips uses spring steel material.
The invention has the benefit that
1, due to there is the U-shaped structure of U-shaped rubber weather strip, Double-protection is played, and it is close by compressing member to compress U-shaped rubber
Strip of paper used for sealing, sealing effect greatly promote.
2, due to there is the use of compressing member, screw during the fastening process, can be to avoid existing cabinet due to welding bring
Deformation influences, to promote cabinet sealing performance, efficiently solves the substances such as water or dust as screw thread gap enters
The problem of cabinet.
3, due to the Double-protection of U-shaped rubber weather strip U-shaped structure, and U-shaped rubber weather strip can be with elastic component
Buffer function is played to a certain extent, is suitable under vibration environment, and panel and cabinet or cabinet and briquetting are this when avoiding vibrating
Collision between rigid member influences product structure.
4, since the U-shaped structure of U-shaped rubber weather strip can wrap up the frame that cabinet needs to seal, so that reducing cabinet needs
The hidden danger such as body incised wound or material incised wound in the brought operating process of the defects of wanting the burr on sealed frame.
