Description
Technical field
It the utility model is related to a kind of gas-particulate filter connection structure, and in particular to a kind of gas-particulate filter is justified with connector
Ring.
Background technology
Civil air defense constructions and installations is a kind of special hypogee for being used for wartime, having requirement of shelter, and the filtering for civil air defense constructions and installations is inhaled
Device is received, it is necessary to there is extremely strong filter effect, the air containing toxic gas, radioactive dust can be effectively filtered, in addition, bomb blast
After can produce enormous impact ripple, although when shock wave reaches gas-particulate filter, overbottom pressure has become very little, but still can be to filtering
Fine filter inside absorber causes to damage, and substantial amounts of dust also be easy to cause fine filter blocking, reduces its service life.
At present, gas-particulate filter connector annulus, its process are：Whole plate is made by processes such as punching press, blanking, flange, chamferings,
Large area punching press clout wastes among plate, and punching course generation burr phenomena is serious, and processing is cumbersome, and has and scratch operation
The security risk of work.
The content of the invention
Goal of the invention：The purpose of this utility model is to overcome deficiency of the prior art, there is provided and one kind shaping is reliable,
Burr phenomena is effectively eliminated, saves material cost, improves the people's air defense special filtering absorber connector annulus of process reliability.
Technical solution：In order to solve the above-mentioned technical problem, a kind of people's air defense special filtering absorber described in the utility model
With connector annulus, it includes annulus body, and the annulus body winds welded shaping by right angle connection side, in the annulus
Be equipped with installing port in the middle part of body, the annulus body includes horizontal connection ring and vertical connection circle, the horizontal connection ring with it is vertical
Direct-connected adapter ring is integrally formed, and mounting hole is equipped with the side wall of the vertical connection circle, in the outer edge of the vertical connection circle
It is equipped with clamping piece.
12 mounting holes are uniformly provided with the side wall of the vertical connection circle.
3 clamping pieces are uniformly provided with the outer edge of the vertical connection circle.
The clamping piece and vertical connection circle are integrally formed.
The horizontal connection ring, vertical connection circle and clamping piece are all stainless steel.
Beneficial effect：Compared with prior art, its remarkable advantage is the utility model：The utility model overall structure is set
Rationally, annulus body is formed by the welded shaping of right angle connection side winding, reduces drawing process, material shaping more may be used
Lean on, effectively eliminate burr phenomena, safe operation, overall precision is high, solves former whole plate and passes through punching press, blanking, flange, chamfering
The problem of causing large area punching press clout waste among plate is made etc. process, saves production cost, is clamped piece and vertical connection
Circle is integrally formed, and use intensity is high, is set multiple mounting holes and clamping piece, is made to be connected firmly, meet actual operation requirements.
Brief description of the drawings
Fig. 1 is the overlooking the structure diagram of the utility model；
Fig. 2 is the positive structure diagram of the utility model.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of people's air defense special filtering absorber connector annulus described in the utility model, it is wrapped
Annulus body is included, the annulus body winds welded shaping by right angle connection side 1, peace is equipped with the middle part of the annulus body
Mouth 2 is filled, the annulus body includes horizontal connection ring 3 and vertical connection circle 4, the horizontal connection ring 3 and vertical connection circle 4 one
It is body formed, mounting hole 5 is equipped with the side wall of the vertical connection circle 4, card is equipped with the outer edge of the vertical connection circle 4
Contact pin 6；12 mounting holes 5 are uniformly provided with the side wall of the vertical connection circle 4；In the outer edge of the vertical connection circle 4
On be uniformly provided with 3 clamping pieces 6；The clamping piece 6 and vertical connection circle 4 are integrally formed；The horizontal connection ring 3, vertically connect
Adapter ring 4 and clamping piece 6 are all stainless steel.It is reasonable that the utility model overall structure is set, by the winding welding of right angle connection side
Composition annulus body is integrally formed, reduces drawing process, material shaping is relatively reliable, effectively eliminates burr phenomena, operation peace
Entirely, overall precision is high, solves former whole plate and causes plate face broad in the middle by the making of the processes such as punching press, blanking, flange, chamfering
The problem of product punching press clout wastes, saves production cost, is clamped piece and vertical connection circle is integrally formed, and use intensity is high, sets
Multiple mounting holes and clamping piece, make to be connected firmly, meet actual operation requirements.
The utility model provides a kind of thinking and method, and it is many to implement method and the approach of the technical solution, with
Only it is the preferred embodiment of the utility model described in upper, it is noted that for those skilled in the art,
On the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications should also regard
For the scope of protection of the utility model, all undefined components in this embodiment can be implemented in the prior art.
