Abstract
The utility model relates to a kind of communication bellows, comprise bellows and the compensated loop being connected to its two ends, the two ends of described bellows have line style section respectively, described line style section is axially plugged in described compensated loop, radially being provided with in described compensated loop can the press part of elastic telescopic, and for the groove of described line style section compressive deformation depression under press part effect.Line style section, by arranging line style section at bellows two ends, is inserted in compensated loop by communication bellows of the present utility model, utilizes the press part radial direction in compensated loop to compress line style section, avoids bellows end facial disfigurement; Because of line style section mutability, in compensated loop, arrange groove, the part of line style section distortion can be absorbed in groove, even if when press part loosens, utilize the effect of groove, also can prevent line style section from sliding axially, there will not be the phenomenon of decylization.
Description
Technical field
The utility model relates to a kind of communication tubing, particularly relates to a kind of bellows communicated.
Background technique
Bellows refers to the tubular elastomeric sensing element connected into along folding retractable direction with collapsible wrinkle sheet.Bellows is widely used in instrument and apparatus, and predominant use is that sealed end is in free state for opening end is fixed.Because the welding performance of bellows is poor, the compensated loop of bellows end can not directly and bellows-welding, existing structure is inlayed at bellows end and compensated loop, mosaic structure can produce two problems because of the expansion coefficient of material: if a magnitude of interference is excessive, distortion can be caused in normal temperature lower end surface; If two magnitude of interference are too small, under operating temperature, the magnitude of interference of decylization may be there is and affect use.
Model utility content
The utility model overcomes the deficiencies in the prior art, provides that a kind of structure is simple, pipe end and the firm and indeformable bellows of compensated loop linkage structure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of communication bellows, it is characterized in that: comprise bellows and the compensated loop being connected to its two ends, the two ends of described bellows have line style section respectively, described line style section is axially plugged in described compensated loop, radially being provided with in described compensated loop can the press part of elastic telescopic, and for the groove of described line style section compressive deformation depression under press part effect.
In the utility model preferred embodiment, comprise described line style section free end further for ease of transitting to the wedge shape in described compensated loop, the sphenoid surface of described line style section is towards the end of described press part.
In the utility model preferred embodiment, comprise described press part further and comprise Returnning spring and be arranged on the pressure section of taper of Returnning spring end, described pressure section can be pressed on the sphenoid surface of described line style section under described action of reset spring.
In the utility model preferred embodiment, comprising described bellows further, to comprise the cross section, ripple place connected of staggering successively be first bellows segment of " V " font and second bellows segment of " one " font, and the diameter of described second bellows segment is less than the diameter of described first bellows segment.
The utility model solves the defect existed in background technique, communication bellows of the present utility model is by arranging line style section at bellows two ends, line style section is inserted in compensated loop, utilizes the press part radial direction in compensated loop to compress line style section, avoid bellows end facial disfigurement; Because of line style section mutability, in compensated loop, arrange groove, the part of line style section distortion can be absorbed in groove, even if when press part loosens, utilize the effect of groove, also can prevent line style section from sliding axially, there will not be the phenomenon of decylization.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
In figure: 10, bellows, 11, line style section, 12, sphenoid surface, the 13, first bellows segment, the 14, second bellows segment, 20, compensated loop, 21, press part, 22, groove, 23, Returnning spring, 24, pressure section.
Embodiment
Be described in further detail the utility model in conjunction with the accompanying drawings and embodiments now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of communication bellows, bellows 10 and the compensated loop 20 being connected to its two ends, the two ends of bellows 10 have line style section 11 respectively, line style section 11 is axially plugged in compensated loop 20, radially arranging in compensated loop 20 can the press part 21 of elastic telescopic, and for the groove 22 of line style section 11 compressive deformation depression under press part 21 acts on.The compensated loop at bellows two ends of the present utility model and the linkage structure of corrugated tube end cast aside traditional mosaic structure, but by arranging line style section at bellows two ends, line style section is inserted in compensated loop, utilize the press part radial direction in compensated loop to compress line style section, because of line style section mutability, groove is set in compensated loop, the part of line style section sex change can be absorbed in groove, even if when press part loosens, utilize the effect of groove, also can prevent line style section from sliding axially.
Preferably, be set to by the free end of line style section 11 be convenient to transit to the wedge shape in compensated loop 20 in the utility model, the sphenoid surface 12 of line style section 11 is towards the end of press part 21.The line style section 11 of wedge shape is when inserting in compensated loop 20, sphenoid surface 12 is less with the frictional force of compensated loop 20, conveniently to be inserted in compensated loop 20 and to utilize sphenoid surface 12 to be extruded laterally by press part 21, press part 21 gives sphenoid surface 12 1 reaction forces simultaneously, firmly can prop up the end of line style section 1, make it can not axial play.
Further, the press part 21 in the utility model comprises Returnning spring 23 and is arranged on the pressure section 24 of taper of Returnning spring 23 end, and pressure section 24 can be pressed on the sphenoid surface 12 of line style section 11 under the effect of Returnning spring 23.
Because line style section 11 can produce deformation under the effect of press part 21, line style section 11 meeting produces the stress to two side stretchings to bellows 10, for adapting to this stress, it is first bellows segment 13 of " V " font and second bellows segment 14 of " one " font that bellows 10 of the present utility model comprises the cross section, ripple place connected of staggering successively, and the diameter of the second bellows segment 14 is less than the diameter of the first bellows segment 13, what connect line style section 11 is the first bellows segment 13.When the two ends of bellows receive the stress stretched laterally, the first bellows segment 13 meeting axial tension of " V " font, have flexible advantage, the end face of bellows can not be out of shape, and can not be destroyed rigidly due to the existence of stress.
Above according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related personnel in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine technical scope according to right.
