In prior art, the screw cap structure of dialyser housing two ends assembling as shown in Figure 3, spiral cover is provided with body 10, the Connection Block 20 for being connected with conduit, the ring portion 30 for coordinating with dialyser shell end, ring portion 30 at spiral cover is provided with a plurality of grooves 40 as folder point, when screwing, the jaw that screws fixture is sandwiched in corresponding groove, by screwing the jaw rotation of fixture, makes spiral cover be tightened against the end of dialyser housing.In actual production, easily occur the uppity situation of jaw, cause occurring that spiral cover assembles underproof situation, jaw reliability is not high in addition, easily occurs damaging.
Therefore, not enough for prior art, provide a kind of dialyser spiral cover very necessary to overcome prior art weak point.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of dialyser spiral cover is provided, this dialyser spiral cover can withstand body by screwing mechanism, by rotation, the muscles and bones application of force is rotated, thereby this dialyser spiral cover is tightened in to the end of dialyser housing, screw assembling firm, screwing mechanism and fixture are not fragile, and service life is longer.
The purpose of this utility model realizes by following technical measures.
A kind of dialyser spiral cover, be provided with body, ring portion and Connection Block, described Connection Block is fixed on the center of described body, described body is fixedly connected with described ring portion, the internal face of described ring portion is provided with for the screw thread with the assembling of dialyser housing, also be provided with many muscles and bones, described muscles and bones is fixed on described body, and described muscles and bones is uniformly distributed in described Connection Block around.
One end of above-mentioned muscles and bones is fixedly connected with described Connection Block.
Above-mentioned muscles and bones and described body, described Connection Block are set to integrated formed structure.
Above-mentioned muscles and bones is set to 5 to 10.
Preferably, above-mentioned muscles and bones is set to 6 or 8.
Above-mentioned dialyser revolves and is also provided with many card articles, and the quantity of described card article equates with the quantity of described muscles and bones, and described card article is fixed on the outside wall surface of described ring portion, and described card article is fixedly connected with described muscles and bones.
Preferably, above-mentioned muscles and bones and described card article are set to integrated formed structure.
A kind of dialyser spiral cover of the present utility model, be provided with body, ring portion and Connection Block, described Connection Block is fixed on the center of described body, described body is fixedly connected with described ring portion, the internal face of described ring portion is provided with for the screw thread with the assembling of dialyser housing, also be provided with many muscles and bones, described muscles and bones is fixed on described body, and described muscles and bones is uniformly distributed in described Connection Block around.This dialyser spiral cover, owing to being provided with many muscles and bones, and many muscles and bones are uniformly distributed in Connection Block around, therefore can withstand body by screwing mechanism, by rotation, the muscles and bones application of force are rotated, thereby this dialyser spiral cover are tightened in to the end of dialyser housing.The active force applying due to screwing mechanism is for body medium position and muscles and bones, therefore, screws assembling firm, and screwing mechanism and fixture are not fragile, and service life is longer.
