A kind of threaded fitting connection rubber sheath
The utility model relates to component of machine technical field, is specifically related to a kind of threaded fitting connection rubber sheath.
It is a kind of to be widely usedly dismountablely fixedly connected with that threaded fitting connects, have structure simple, connect the advantages such as reliable and mounting or dismounting are convenient.Threaded fitting connects and has self-locking performance, tightens and generally can not to loosen afterwards, but under shock and vibration or varying load effect, and high temperature or temperature variation larger time, the frictional force between Deformed Steel Bars can reduce or disappear, and connection just may loosen.In addition, use in wet environment if this kind of pipe fitting is long-term or accidentally intakes around it, pipe fitting screw thread all can be caused to get rusty, affecting its dismounting and maintenance, reduce the working life of pipe fitting simultaneously.
Model utility content
Technical problem to be solved in the utility model is the threaded fitting connection rubber sheath providing a kind of structure simple, reasonable in design, easy to use.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of threaded fitting connection rubber sheath, comprise sheath body, described sheath body is formed by connecting by thick muzzle pipe and thin muzzle pipe, the outer tube wall of described thick muzzle pipe and thin muzzle pipe is respectively equipped with two stiffening ribs, inner tubal wall is evenly provided with many hangnails, and the inner side connection part of described thick muzzle pipe and thin muzzle pipe is provided with fold.
Described stiffening rib is arcuation stiffening rib.
The beneficial effects of the utility model are: the utility model not only has the function of shockproof, waterproof, sealing, and have and install firmly, difficult drop-off, cracking, the feature of long service life.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model;
Wherein: 1-sheath body; The thick muzzle pipe of 2-; The thin muzzle pipe of 3-; 4-stiffening rib; 5-hangnail; 6-fold.
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, 2, a kind of threaded fitting connection rubber sheath, comprise sheath body 1, sheath body 1 is formed by connecting by thick muzzle pipe 2 and thin muzzle pipe 3, the outer tube wall of thick muzzle pipe 2 and thin muzzle pipe 3 is respectively equipped with two stiffening ribs 4, inner tubal wall is evenly provided with many hangnails 5, it is all the sealing in order to strengthen rubber sheath, stiffening rib is arcuation stiffening rib, and be provided with fold 6 at the inner side connection part of thick muzzle pipe 2 and thin muzzle pipe 3, to reduce the impact force of extraneous threaded elements, improve the working life of threaded fitting.The utility model have dust-proof, waterproof, high temperature resistant, install firmly, the feature of difficult drop-off and cracking.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
