Description

A kind of bellows

Technical field

The utility model relates to a kind of bellows, and more particularly, it relates to a kind of wear-resisting bellows.

Background technology

Bellows is a kind of wavy tubing of profile rule, mainly comprises metal bellows and plastic film capicitor, and plastic film capicitor has irreplaceable effect in fields such as medium transport, electric power threading, lathe, household electrical appliances in fact.

What be wherein most widely used is exactly in electric power threading, because the cable of electric power transfer needs the fail safe ensureing that it is higher, but when being arranged on the external world or underground, the pollution of the corrosion or water that are easily subject to air causes the fault that electric leakage power-off occurs, security performance is affected, therefore bellows usually can be used to protect cable when cable transmission, it is prevented to be subject to sunlight, moisture content, the invasion of insect, but in use, first that bellows is fixed-type often, then cable is put in bellows and drag, until forget about it the place needing to install, the wearing and tearing of bellows inwall can be caused like this, thus the shape of bellows and useful life are affected, and because of bellows, when protecting cable, residing environment can be relatively severe, easy generation is aging, fracture and easily got into the cave by mouse insect bite food, cause greatly reduce the useful life of bellows, its cable line protected can be caused so also to impact, therefore be necessary that proposing a kind of new scheme solves the problems referred to above.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of resistance to wear is good, not yielding, the bellows of long service life.

For achieving the above object, the utility model provides following technical scheme: a kind of bellows, comprise body, described body is formed with some grooves with protruding, the surface uniform of described projection is coated with wearing layer, also one-body molded in described groove have reinforcement, and be formed with cavity between described reinforcement and body, the outer surface of described body is evenly coated with weathering layer.

As preferably, described weathering layer surface is also coated with insect protected coating.

As preferably, in described cavity, strutting piece is installed.

As preferably, the thickness of described wearing layer is 0.4mm ~ 0.8mm.

As preferably, the thickness of described weathering layer is 0.2mm ~ 0.6mm.

As preferably, the thickness of described insect protected coating is 0.4mm ~ 0.6mm.

As preferably, described strutting piece is made up of steel wire.

Compared with prior art the utility model has following advantage: by having reinforcement the inboard wall groove place of bellows body is one-body molded, and be formed with cavity between reinforcement and body, this makes it possible to the structural strength greatly strengthening body, make it that bending be less likely to occur, and the high spot on inboard wall of tube body is evenly coated with wearing layer, like this when body installs, when cable drags in body and high spot rub, frictional layer effectively can increase the rubbing fastness of body, thus it is damaged to prevent body from occurring, and evenly weathering layer is coated with on the outer wall of body, for increasing the ageing resistance of body, scrubbing and Exposure to Sunlight of wind and rain can be withstood, ensure that body can not corrode, this makes it possible to that bellows is reached and there is higher structural strength, resistance to wear is good, not easily aging, the object of long service life.

Accompanying drawing explanation

Fig. 1 is the cross-sectional view of embodiment.

In figure: 1, body; 2, protruding; 3, groove; 4, reinforcement; 5, strutting piece; 6, wearing layer.

Embodiment

With reference to Fig. 1, a kind of bellows of the utility model is described further.

As shown in Figure 1, the body 1 of bellows forms spaced protruding 2 and groove 3 in the wavy wall that sets within it, one-body molded in groove 3 have reinforcement 4, one is formed between the two side of reinforcement 4 and groove 3, and be formed with cavity between the diapire of reinforcement 4 and groove 3, strutting piece 5 is interspersed with in cavity, the steel wire that strutting piece 5 is preferably thinner softness is made, whole like this bellows tends to distortion during when being subject to the extruding of outside or inside, reinforcement 4 effectively can increase the bending resistance of bellows, it is made to be not easy the distortion that is crushed, the cavity formed effectively can change the institutional framework of inboard wall of tube body, make the direction of the internal organizational structure between reinforcement 4 part and body 1 and not quite identical, in order to when being subject to the pressure on different directions, bellows all can effectively be supported like this, can not deform, thus ensure that the cable of bellows interior can not be oppressed, thus ensure that the fail safe of cable, and strutting piece 5 effectively can increase the anti-pull property of bellows, the phenomenon of fracture is there is when preventing from being stretched, the structural strength on bellows vertical direction can be increased simultaneously, and the surface at projection 2 place in body 1 is also evenly coated with wearing layer 6, wearing layer 6 is made up of TiSiN coating, TiSiN coating layer thickness gets 0.4mm ~ 0.8mm, this TiSiN coating knownly at present has extreme hardness, there is the wear-resistant paint of superregulated performance, China knows in " preparation of TiSiN coating and the performance study thereof " of online Yan Guangyuan master and describes the preparation method of this coating and specific performance, here do not add and repeat, like this when cable drags in body 1, the wearing layer 6 on protruding 2 surfaces and cable generation CONTACT WITH FRICTION, wearing layer 6 can withstand the friction of more number of times and loss can not occur, and can not be damaged by effective guarantee bellows, thus extend the useful life of bellows.

Certainly comparatively preferably also evenly weathering layer is coated with at the outer surface of body 1, weathering layer is made up of weather-resistant coating, the thickness of weathering layer is arranged on 0.2mm ~ 0.6mm, weather-resistant coating can adopt the patent No. to be the weatherability coating that " CN1294215C " introduces, when this coating is evenly coated in the outer surface of body 1, effectively can absorb ultraviolet, ensure that deterioration by oxidation phenomenon can not occur body 1, thus the useful life of body 1 is effectively strengthened, more preferably also evenly be coated with insect protected coating on the surface of weathering layer, insect protected coating is evenly coated in weathering layer surface by insect paint, the thickness of wherein insect protected coating is arranged on 0.4mm ~ 0.6mm, wherein insect protected coating has certain peculiar smell and does not go near bellows after making to want close worm mouse to smell smell, this makes it possible to the function effectively reaching expelling parasite, available protecting bellows, below just reach that to make bellows have resistance to wear good, not yielding, good weatherability, the not easily object of aging long service life.

The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
