Abstract
The utility model relates to a vehicular air conditioner rubber sealing member which comprises an annular sealing member body, wherein elastic transverse annular edges are arranged at the upper end and the lower end of the sealing member body, the sealing member body is internally provided with a rigid supporting structure keeping the fixed shape of the sealing member body, and an installation hole is arranged on the sealing member body. The sealing member is provided with the elastic transverse annular edges that are used for blocking seams among pipelines when the pipelines are connected, so that the sealing property of the whole pipeline is improved, the rigid supporting structure in the sealing member body leads the sealing member to difficultly deform in radial direction, the possibilities of leakage caused by deformation of the sealing member due to stress can be decreased, the service life of the sealing member is prolonged, the structure is simple and the sealing effect is good.
Description
Technical field
The utility model relates to rubber sealing device, especially relates to the rubber seal of car air-conditioner ventilation duct.
Background technique
In the fluid-transporting tubing, Sealing is to influence the critical component that pipe fitting connects sealing, O-ring seals is the typical part of annular rubber sealing element, it uses extremely extensive in sealing occasions such as axis hole cooperation, end face seals, it is modal a kind of Sealing, for the work that guarantees that seal ring can be permanently effective, except the material of compressibility, amount of tension and the seal ring of choose reasonable seal ring, rational axis hole quality of fit must be arranged also.When determining the compressibility of seal ring, should guarantee that seal ring can be subjected to enough sealing surface contact pressures, the little frictional force of trying one's best and avoid producing permanent deformation because of biasing, in the practical set process, if magnitude of interference is too big, seal ring is easy to be sheared damage, otherwise seal ring loses envelope again easily, under the conditional request of high pressure, high vacuum, high elasticity sealing, higher to the accuracy of manufacturing requirement of O-ring seals.The poor sealing performance of common Sealing; working life is short, can't glue together pipe fitting ends such as pipe, plastic-aluminum pipe to the bilayer of modern extensive use and be subjected to protections such as industrial chemicals erosion, oxidation, corrosion, and it is low to bear pressure; easily cause pipeline gas leakage, leak, cause environmental pollution.The using effect of car air-conditioner and the sealability of its ventilation duct have close getting in touch, and the power of on-board air conditioner is generally little, if pipeline has gas leak phenomenon again, and the inevitable utilization efficiency that reduces air-conditioning greatly, and waste energy, increase toxic emission.Especially in high-grade car, the warm effect of refrigeration, system of on-board air conditioner and aspect such as quiet, energy-conservation are all had higher requirement, therefore, the airtight performance and the working life of improving car air-conditioner ventilation duct Sealing are very important.
The model utility content
The purpose of this utility model provides a kind of good sealing effect, car air-conditioner rubber seal easy for installation.
The utility model is that the technological scheme that its technical problem of solution is adopted is,
The car air-conditioner rubber seal comprises an annular seal body, and described seal body upper and lower end is provided with elasticity lateral loops limit.
Be provided with the rigidity supporting structure that makes seal body be maintained fixed shape in the described seal body.
Described seal body is provided with mounting hole.
The beneficial effects of the utility model are, the Sealing that is provided is provided with flexible lateral loops limit, when pipeline connects, the seam of pipeline enclosure is blocked on the ring limit, improves the airtight performance of whole pipe, and the rigidity supporting structure in the seal body makes Sealing radially be not easy distortion at it, reduced to cause the possibility of leakage because of the Sealing compressive deformation, also improved the working life of Sealing, it is simple in structure, and sealing effect is good.

Fig. 1 is the front view of the utility model car air-conditioner rubber seal;
Fig. 2 is the plan view of car air-conditioner rubber seal;
Fig. 3 is the A-A view of Fig. 2;
Among the figure, 1. seal body is 2. encircled the limit, 3. ring limit, 4. mounting hole, 5. screw.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and embodiment, further set forth the utility model.
Fig. 1 is the front view of car air-conditioner rubber seal, seal body 1 is the rectangular rubber ring of four jiaos of slynesses in the present embodiment, there is circular rigid support its inside, the vertically mutual displacement meeting of pipeline enclosure produces longitudinal frictional force to Sealing in the use, the pressure of pipeline enclosure also can make Sealing produce radially deformation, be easy to cause gas leakage, Sealing is being worn out rapidly under the active force in many ways, reduction of service life, add and do not allow yielding rigid support, the shape that whole Sealing is maintained fixed had both been avoided the gas leakage that causes because of Sealing deformation, the life time that has also prolonged Sealing; Seal body 1 upper end is provided with trumpet-shaped ring limit 2, ring limit 2 is made by flexible rubber material, can be close to the pipe fitting that is connected, improve obturation effect, the seal body lower end is provided with ring limit 3, and mounting hole 4 is arranged at the joint of ring limit 3 and seal body 1, is provided with each three mounting hole of both sides in the present embodiment, being connected and fixed when six mounting holes provide Sealing to use altogether, present embodiment are used screw 5 fixing whole Sealings.
When pipeline connects, the seam of pipeline enclosure is blocked on the ring limit, improve the airtight performance of whole pipe, and frictional force, pressure that pipeline enclosure is produced play buffer function, rigidity supporting structure in the seal body makes Sealing radially be not easy distortion at it, has reduced to cause because of the Sealing compressive deformation possibility of leakage, the working life of also having improved Sealing, it is simple in structure, and sealing effect is good.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
