Like this, through the cooperation of jump ring 4 and edge rolling 11, can greatly improve sealing washer 3's stability, further avoid sealing washer 3 pine to take off.
It should be noted that the annular side plate of the present invention may be a part of the main body of the inner cylinder assembly 1; or may be a portion formed on the body of the inner barrel assembly 1. That is, the size of the annular side plates may or may not be consistent with the size of the main body portion of the inner barrel assembly 1.
The invention aims to overcome the existing problems and provide a novel structure which is simple in structure, convenient to assemble and good in sealing stability.
The invention is realized by the following technical scheme: adopt the jump ring fastening structure of brand-new design, on this structure inner tube subassembly and felt (being sealing washer 3) assembly structure's basis, increase the elasticity jump ring in the felt outer lane, can solve through this structure because the clearance between inner tube subassembly 1 and the inner tube support 2 that the assembly of inner tube subassembly and felt is unstable causes is too big, the poor problem of leakproofness that leads to, effectively improve the drying performance of dryer, improved the stability of complete machine stoving performance greatly.
The invention has the advantages that: simple structure, the equipment is convenient, has taken the design that increases the jump ring in the felt outer lane, has greatly promoted the stoving performance of complete machine, has reduced because the unstable clearance that causes of assembly of inner tube subassembly and felt is too big between inner tube and the preceding support, the leakproofness problem that leads to.
The clamp spring 4 mainly comprises a steel ring 41 and a spring 42, wherein the steel ring 41 is connected with the spring 42 through a clamping hook structure;
The clamp spring 4 is fastened on the felt outer ring (namely the outer side part 31 of the sealing ring 3) by using the tension force of the spring 42, and the spring 42 is always in a stretching state. The front end of the inner cylinder component 1 adopts a structure of the edge rolling 11, so that the clamp spring 4 can be effectively limited in the operation process of the whole machine, and the stability of the clamp spring 4 in the operation process of the whole machine is also ensured by the surface friction force of the felt. Under the action of the tension force of the clamp spring 4, the stability of the assembly position of the felt is high, so that the sealing stability of the whole machine in operation is ensured, and the stability of the drying performance of the whole machine is greatly improved.
The inner cylinder component 1 is assembled with the inner cylinder support 2 after being provided with the felt and the clamp spring 4. The end face of the felt is in close contact with the end face of the inner cylinder support 2, so that a good sealing state in the cylinder is realized when the whole machine operates. The clamp spring 4 can effectively avoid the contact gap between the end face of the felt and the end face of the inner cylinder support 2 in the actual assembly process, and the stability of end face sealing is ensured. Thereby effectively improving the drying performance of the clothes dryer and ensuring the stability of the drying performance.
