Abstract
The utility model belongs to bellows, particularly a kind of compound bellows.Compound bellows, it straight length comprising two sections and the bellows segment be connected between straight length, the end of described straight length is provided with the locking nut be connected with other devices, it is characterized in that: described bellows segment has the crest section of circular arc and connects the trough section formation of adjacent wave crest segment, described trough section is circular arc, and described bellows segment and the outside of straight length are coated with cushion rubber layer.The utility model devises a kind of combined type bellows; cushion rubber layer and rubber layer is provided with respectively at the outer surface of bellows and inwall; the cushion rubber layer arranged on the one hand can be protected the outer wall of bellows; avoid it exposed in malaria; avoid the too early generation of corrosion phenomena, extend the working life of bellows.
Description
Technical field
The utility model belongs to bellows, particularly a kind of compound bellows.
Background technique
The general all straight tubes of existing bellows are directly compressed into corrugated, due to compressing, the tube wall of bellows is directly in atmosphere exposed, in use there are the following problems: 1, because the tube wall of bellows is directly exposed in air, and general bellows is all in comparatively moist environment, the ripple of bellows adopts extruded, the metal surface of bending part is impaired, easily there is the problem of corrosion, 2, bellows is directly exposed, there is the situation of shock in using process, easily cause bellows to be out of shape, affect the bending of bellows.
Model utility content
The utility model is for the deficiencies in the prior art, the utility model devises a kind of combined type bellows, cushion rubber layer and rubber layer is provided with respectively at the outer surface of bellows and inwall, the cushion rubber layer arranged on the one hand can be protected the outer wall of bellows, avoid it exposed in malaria, avoid the too early generation of corrosion phenomena, extend the working life of bellows, a protection can be carried out on the other hand to bellows, prevent from being directly subject to external impact, avoid the generation of bending over-education phenomenon, the rubber layer that inwall is arranged can carry out a protection to the inwall of bellows.
The utility model is achieved through the following technical solutions:
Compound bellows, it straight length comprising two sections and the bellows segment be connected between straight length, the end of described straight length is provided with the locking nut be connected with other devices, it is characterized in that: described bellows segment has the crest section of circular arc and connects the trough section formation of adjacent wave crest segment, described trough section is circular arc, and described bellows segment and the outside of straight length are coated with cushion rubber layer.
Described straight length and the inside of bellows segment are also provided with rubber layer.
In sum, the utility model has the following advantages:
The utility model devises a kind of combined type bellows; cushion rubber layer and rubber layer is provided with respectively at the outer surface of bellows and inwall; the cushion rubber layer arranged on the one hand can be protected the outer wall of bellows; avoid it exposed in malaria; avoid the too early generation of corrosion phenomena; extend the working life of bellows; a protection can be carried out on the other hand to bellows; prevent from being directly subject to external impact; avoid the generation of bending over-education phenomenon, the rubber layer that inwall is arranged can carry out a protection to the inwall of bellows.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the utility model will become apparent.Wherein:
Fig. 1 is structural representation of the present utility model;
In figure, 1 is locking nut, and 2 is straight length, and 3 is bellows segment, and 4 is rubber layer, and 5 is trough section, and 6 is crest section, and 7 is cushion rubber layer.
Embodiment
Compound bellows as shown in Figure 1, it straight length 2 comprising two sections and the bellows segment 3 be connected between straight length, the end of described straight length 2 is provided with the locking nut 1 be connected with other devices, it is characterized in that: described bellows segment 3 has the trough section 5 of the crest section 6 of circular arc and connection adjacent wave crest segment to form, described trough section 5 is in circular arc, and described bellows segment 3 and the outside of straight length 2 are coated with cushion rubber layer 7.
Described straight length 2 and the inside of bellows segment 3 are also provided with rubber layer 4.
In sum, the utility model has the following advantages:
The utility model devises a kind of combined type bellows; cushion rubber layer and rubber layer is provided with respectively at the outer surface of bellows and inwall; the cushion rubber layer arranged on the one hand can be protected the outer wall of bellows; avoid it exposed in malaria; avoid the too early generation of corrosion phenomena; extend the working life of bellows; a protection can be carried out on the other hand to bellows; prevent from being directly subject to external impact; avoid the generation of bending over-education phenomenon, the rubber layer that inwall is arranged can carry out a protection to the inwall of bellows.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model namely openly in scope; still can do some revise or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
