In above-mentioned encapsulating cover for dialyzer structure, the lid uses PP materials with the circle body.
A kind of encapsulating cover for dialyzer structure that above-mentioned technical proposal is provided, compared with prior art, advantage is,
It is caught in bulge loop and first embedding groove by described first, described second is caught in mistake between bulge loop and second embedding groove
It is full of cooperation, it is ensured that the leakproofness coordinated between the lid and the circle body, the assembly being equipped with by the inner wall of the circle body
Slot reaches the interference fit damascene structures between circle body and the dialyzer shell, overall sealing performance is made to be guaranteed.

Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Please refer to attached drawing 1-3, a kind of encapsulating cover for dialyzer structure provided by the utility model comprising lid 10 and with
The circle body 20 that the lid 10 coordinates；The lid 10 includes substrate and is caught in bulge loop on the substrate, described to be caught in
Bulge loop is caught in bulge loop 1 and second including first and is caught in bulge loop 2, is coordinated with the circle body 20 by the bulge loop that is caught in；The circle
Body 20 be equipped with embedding groove, the embedding groove be set to the circle body 20 and the lid 10 mating surface, the embedding groove include with
Described first the second edge for being caught in the first embedding groove 3 of the interference fit of bulge loop 1 and being caught in the interference fit of bulge loop 2 with described second
Caulking groove 4 improves the circle body 20 and the lid by the embedding groove and the corresponding interference fit being caught between bulge loop
Fitted seal between body 10, the leak adhesive situation occurred when injecting glue being avoided to centrifuge.
The inner wall of the circle body 20 is equipped with the fitting groove 5 for being interference fitted with dialyzer shell, passes through the fitting groove
5, so that the being completely embedded property between circle body 20 and the dialyzer shell is guaranteed, further increases leakproofness.
Encapsulating cover for dialyzer structure based on above-mentioned technical characteristic is caught in bulge loop 1 by described first and is inlayed with described first
Caulking groove 3, described second are caught in interference fit between bulge loop 2 and second embedding groove 4, it is ensured that the lid 10 with it is described
The leakproofness coordinated between circle body 20, the fitting groove 5 being equipped with by the inner wall of the circle body 20, reaches circle body 20 and dialyzer shell
Interference fit damascene structures between body, make overall sealing performance be guaranteed.
In the present embodiment, described first be caught in bulge loop 1 cross section it is triangular in shape；Described second is caught in the cross of bulge loop 2
Section is trapezoidal；First embedding groove 3 is the rectangular channel equipped with chamfering；Second embedding groove 4 is half dovetail groove；It uses
The described of above structure is caught in bulge loop and the embedding groove, when being interference fitted, can further improve the circle
Leakproofness between body 20 and the lid 10 increases the being completely embedded property between the circle body 20 and the lid 10, it is ensured that
The stability of injecting glue centrifugal work
Further, the fitting groove 5 is dovetail groove, can increase the circle body 20 and match with the progress interference of dialyzer shell
The tight ness rating of leakproofness and connection when conjunction.
