Abstract
The utility model provides a sleeve which is characterized in that a plurality of dentiform grooves are evenly arranged on an inner wall of the sleeve and the outer surface of the sleeve is provided with a zinc coating. According to the sleeve, the dentiform grooves on the inner wall mutually clamp down on a rubber pipe easily after matching with the rubber pipe, the sealing of the sleeve is firmer, the sleeve is not prone to be disconnected, and the zinc coating on an outer wall can also resist a corrosion effect from the external service environment.
Description
Technical field
The utility model relates to a kind of sleeve.
Background technique
Sleeve is as the accessory commonly used in the hydraulic tube piece, be mainly used in being socketed on the pipe fitting joint, be socketed by the rubber pipe transition between sleeve and the pipe fitting joint, in order to avoid collision causes damage, but in long-term the use, because environmetal impact, sleeve easily and rubber pipe come off or seal insecurely, cause product quality problem.
The model utility content
In order to overcome above-mentioned technical problem, the utility model provides a kind of sleeve.
Concrete technological scheme is as follows:
A kind of sleeve is characterized in that: the uniform some roads of sleeve lining profile of tooth groove, sleeve outer surface has zinc coat.
Beneficial effect:
Sleeve of the present utility model, inwall profile of tooth groove be easy to the rubber pipe drive fit after clamp down on mutually, sealing firmly is difficult for throwing off more, the outer wall zinc coat also can well be resisted the corrosive action of outside Environmental Conditions.
Description of drawings
Fig. 1 is the utility model tube-in-tube structure schematic diagram.
Among the figure: 1-profile of tooth groove.
Embodiment
By reference to the accompanying drawings the utility model is described further.
A kind of sleeve, the uniform some roads of sleeve lining profile of tooth groove 1, sleeve outer surface has zinc coat.
At last, it is also to be noted that, what more than enumerate only is specific embodiment of the utility model, and obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
