Description

Vehicle door sealing rubber strip

Technical Field

The utility model relates to an adhesive tape especially relates to a door joint strip.

Background

As the train of the motor train unit has higher requirement on sealing performance, the door system of the motor train unit needs to have good watertight performance and airtight performance. The door plant of current EMUs door installs "splayed" shape joint strip usually, through joint strip and the door frame compress tightly the sealed effect that the laminating realized the door system.

The existing door panel sealing rubber strip has some problems in the manufacturing and using processes: after the adhesive tape is arranged in the door plate, sealant needs to be applied to the root of the adhesive tape, otherwise, air leakage and water seepage can occur. Beat and glue and need guarantee that the door plant border is even, the operation degree of difficulty is great to beat and glue the back and need additionally increase the solidification and the clear time of gluing of sealed glue, cause production efficiency to reduce, the cost increase. In addition, when the splayed sealing rubber strip is applied to a vehicle, the elasticity of the rubber strip is reduced because the splayed lip edge is pressed on a door frame for a long time, the sealing performance of a door plate is obviously reduced along with the deformation of the splayed lip edge, and the service life of the rubber strip is greatly shortened.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a sealed effectual, long service life's door joint strip between respectively and door plant mounted position and the sealed face.

When the vehicle door is closed, the sealing rubber strip on the door plate is extruded with the door frame, and a sealed joint part is formed between the extension part of the rubber strip positioned at one side/two sides of the door plate along the lower edge of the door plate and the door plate, so that the sealing at the mounting position of the sealing rubber strip is realized; simultaneously, realize sealedly because of the extrusion between sealing and the door frame, consequently, the utility model discloses can realize whole sealed effect between door plant and the door frame. And, rationally set up the three-layer material layer, make the extension be the foam rubber material layer, this part needs stronger resistance to compression deformability, and uses closely knit rubber material layer respectively to the root of adhesive tape, the part with door frame direct contact, can not produce too big frictional resistance closing the door the process, and has avoided using the easy damaged shortcoming of foam adhesive tape material. The design of three material layers prolongs the life of adhesive tape greatly.

Has the advantages that: compared with the prior art, the utility model discloses following beneficial effect has: 1. not only can realize the sealed between adhesive tape and the door frame, utilize the extension of adhesive tape to also realize the sealed between and the door frame moreover, whole sealed effectual, long service life. 2. The extension part replaces the gluing process in the original rubber strip installation, greatly reduces the manufacturing difficulty and shortens the production period. 3. Adopt the compound structure of foam rubber layer and closely knit rubber layer, the too big deflection of production can be avoided on the one hand foam material layer, the installation of being convenient for to the life of adhesive tape has been prolonged, the closely knit rubber layer of on the other hand can not cause the influence to the door closing process. 4. The door frame structure can be suitable for the existing door plate and door frame structure, and can not influence other functions and performances of the vehicle door. 5. The structure is simple and reliable, and the reliability and the economy are good.
