The utility model discloses further set up to: the inner wall of the extension part is coated with two adhesive layers which are divided into an inner CH205 adhesive layer and an outer CH220 adhesive layer.
By adopting the technical scheme, the CH205 and the CH220 are adhesives of rubber and metal, the high-strength bonding effect is achieved, the CH205 adhesive layer is coated on the inner wall of the extension part firstly, the CH220 adhesive layer is coated after drying, the outer pipe is bonded on the rubber sleeve through the adhesive layer, and therefore gaps are prevented from appearing between the extension part on the outer pipe and the rubber sleeve, and the outer pipe is loosened.
The utility model discloses further set up to: the rubber sleeve is characterized in that an annular cavity which is coaxial with the rubber sleeve is arranged inside the covering part of the rubber sleeve, a buffer protection tube is embedded in the annular cavity, and two ends of the buffer protection tube are respectively abutted against the two extending parts.
Through adopting above-mentioned technical scheme, be provided with the buffering protection tube in rubber sleeve's cover portion, can reduce rubber sleeve's the deformation range that takes place to a certain extent, extrude rubber sleeve behind the outer tube atress, and then rubber sleeve will some power effects at the buffering protection tube, unload the power through the buffering protection tube, and then improve rubber sleeve's shock attenuation effect.
The utility model discloses further set up to: the rubber sleeve is made of NR natural rubber, a tear-resistant canvas layer is further arranged inside the rubber sleeve, and the canvas layer is three-layer and is uniformly distributed.
By adopting the technical scheme, the NR natural rubber is mainly composed of rubber hydrocarbon (polyisoprene) and contains a small amount of protein, moisture, resin acid, saccharides, inorganic salt and the like. The rubber sleeve is large in elasticity, high in stretching strength, good in tear resistance and electrical insulation, good in wear resistance and drought resistance, and easy to adhere to other materials, so that the rubber sleeve is manufactured by adopting the material, and the working strength of the rubber sleeve is high, so that the tear resistance of the rubber sleeve is further improved, three layers of canvas layers are arranged in the rubber sleeve, and the canvas layers play a role in connecting ribs, so that the rubber sleeve is prevented from being damaged after exceeding a deformation range.
