Description
Technical field
The utility model belongs to gasket techniques field, particularly relates to a kind of buffer gasket of transition between unlike material structure.
Background technique
Often need when Liang Ge mechanism assembles to install packing ring additional, packing ring is that some packing ring also can play seal action for increasing the Area of bearing of connected compcnent to reduce the protection device of the pressure of contacting point.But current packing ring great majority are metal ring, rubber ring or both combinations, for the different mechanism of two materials with the use of situation, because material difference causes the character such as the expansion coefficient of two mechanisms inconsistent, so also different to the wear intensity of packing ring, it is different and complicated that obvious simple packing ring cannot meet assemble mechanism material, to the requirement of packing ring durability during work under bad environment, in addition, also there is function singleness in existing packing ring, the problem that turnover rate is high.
Summary of the invention
In view of this, the utility model provides a kind of buffer gasket of transition between unlike material structure, and single to solve current gasket function, turnover rate is high, assemble mechanism material cannot be met different and complicated, to the technical problem of the requirement of packing ring durability during work under bad environment.
The technological scheme that the utility model adopts: a kind of buffer gasket of transition between unlike material structure, it is characterized in that, comprise inner ring, outer ring, adhesive plaster and offset plate, described offset plate two ends are fixedly connected with outer ring with described inner ring respectively, the upper surface of described inner ring and outer ring all offers the circular cavity for holding adhesive tape, described adhesive plaster is compressed by described adhesive tape and is embedded in described circular cavity, is equipped with absorbent wool between described offset plate and adhesive plaster.
Preferably, the lower surface of described inner ring and outer ring offers circular cavity equally, and symmetry be provided with adhesive plaster, be fixed in circular cavity by adhesive tape, namely the mechanism that laterally zygomorphic formation is identical, increase buffer capacity, and material and the thickness of described adhesive plaster can be selected according to actual needs, adapt to be connected of unlike material.
Preferably, described circular cavity offers oral area, so that put into described adhesive tape, wherein, the oral area of described circular cavity is semiclosed opening, and semi-enclosed opening can avoid adhesive tape to deviate from, and plays the effect of fastening described adhesive tape.
Preferably, be provided with some glueballs in described circular cavity, described glueballs increases the frictional force of adhesive tape and described circular cavity inner wall, is convenient to more stable fixing described adhesive plaster.
Beneficial effect: the packing ring up-down structure that the utility model provides is different, can adapt to the assembling of to be connected of unlike material; Adhesive plaster can be changed at any time, and can embed the adhesive plaster of different-thickness and material according to working environment, improves the adaptivity of packing ring; Absorbent wool not only plays buffer function further, and Absorbable rod excessive moisture, and reduction wet environment or other mal-conditions treat the corrosion of link, improves the durability of packing ring entirety.
Accompanying drawing explanation
Fig. 1 is the plan view that the utility model embeds the buffer gasket of adhesive plaster.

Fig. 3 is the A-A view of Fig. 1 of embodiment 2.
Embodiment
The following description and drawings illustrate specific embodiment of the invention scheme fully, to enable those skilled in the art to put into practice them.Embodiment only represents possible change.Unless explicitly requested, otherwise independent parts and function are optional, and the order of operation can change.The part of some embodiments and feature can be included in or replace part and the feature of other embodiments.The scope of embodiment of the present invention comprises the gamut of claims, and all obtainable equivalent of claims.
Embodiment 1:
As illustrated in fig. 1 and 2, provide a kind of buffer gasket of transition between unlike material structure, comprise inner ring 1, outer ring 2, adhesive plaster 3 and offset plate 4.Described inner ring 1 is fixedly connected with by described offset plate 4 with outer ring 2, wherein, described inner ring 1, outer ring 2 and offset plate 4 are formed in one structure, or, got up to use by the combination of materials of unlike material, namely the material of inner ring 1 and outer ring 2 is Nitrile Rubber, butadiene-styrene rubber, hydrogenated butyronitrile glue, ethylene-propylene diene copolymer, silica gel, fluorine glue, neoprene, one or more of FFKM, described offset plate 4 is chosen as metal material or identical with the material of outer ring 2 with described inner ring 1, one machine shaping.
Described inner ring 1 and outer ring 2 all offer circular cavity 5, and for holding adhesive tape 6, described adhesive plaster 3 is ring, and the inner circle of adhesive plaster 3 and cylindrical compress by described adhesive tape and be embedded in described circular cavity 5.The thickness of described offset plate 4 is less than the thickness of inner ring 1 and outer ring 2, namely between described offset plate 4 and adhesive plaster 3, certain space is had, be used for placing absorbent wool 7, absorbent wool 7 not only plays buffer function further, and Absorbable rod excessive moisture, reduction wet environment or other mal-conditions treat the corrosion of link, improve the durability of packing ring entirety.
Wherein, the material of described adhesive plaster 3 and adhesive tape 6 is similarly Nitrile Rubber, butadiene-styrene rubber, hydrogenated butyronitrile glue, ethylene-propylene diene copolymer, silica gel, fluorine glue, neoprene, one or more of FFKM.
Described circular cavity 5 offers oral area, so that put into described adhesive tape 6, preferably, the diameter of described adhesive tape 6 is slightly larger than the width of described circular cavity 5, so that fixing adhesive plaster 3, but or the unexpected situation that adhesive tape comes off can occur, so, the oral area of described circular cavity 5 can be designed to semiclosed opening, and semi-enclosed opening can avoid adhesive tape 6 to deviate from, and plays the effect of fastening described adhesive tape 6.
Further, be provided with some glueballs 8 in described circular cavity 5, described glueballs 8 increases adhesive tape 6 and the frictional force of described circular cavity 5 inwall, is convenient to more stable fixing described adhesive plaster 3.
Embodiment 2:
As shown in figs. 1 and 3, difference from Example 1 is that the lower surface of described inner ring 1 and outer ring 2 offers circular cavity 5 equally, in like manner, adhesive plaster 3 is fixed in circular cavity 5 by adhesive tape 6, namely the up-down structure of buffer gasket is symmetrical, not only can increase buffer capacity, and material and the thickness of described upper and lower two-layer adhesive plaster can be selected according to actual needs, adapt to be connected of unlike material.
The adhesive plaster 3 of lower surface is same with between described offset plate 4 prevents absorbent wool 7, same, can select the thickness of absorbent wool according to actual needs.
The design of other oral areas as circular cavity 5, glueballs 8, adhesive plaster 3, adhesive tape 6, inner ring 1, outer ring 2, offset plate 4 and its material are identical with embodiment 1, repeat no more here.
Above-described embodiment is the utility model preferably mode of execution; but mode of execution of the present utility model is not restricted to the described embodiments; other are any do not deviate from Spirit Essence of the present utility model and principle under the change made; modify; substitute, combination, simplify; all should be the substitute mode of equivalence, all should be included in protection domain of the present utility model.
