Technical field
The utility model relates to hermetically-sealed construction, particularly a kind of rail traffic platform sliding door of screen door hermetically-sealed construction.
Background technology
Track traffic has become a kind of common public transit systems in modern metropolis, in order to protect passenger getting on/off safety, railway platform is provided with shield door.Guarantee that by shield door the train back passenger of entering the station stands on a home all the time and waits.Enter the station tail gate and sliding door of screen door of train opened, and the passenger can enter in the train.After the passenger entered train, train car door and sliding door of screen door were closed, and train can roll platform away from.
But might there be certain slit in sliding door of screen door after closing, and causes the wasting of resources cold in the platform, heating installation.And also influenced the aesthetic of shield door integral body to a certain extent.
The utility model content
The purpose of this utility model in order to overcome the defective that above-mentioned prior art exists, provides a kind of simple in structure, reliable rail traffic platform sliding door of screen door hermetically-sealed construction exactly.
To achieve these goals, the utility model has adopted following technical scheme: a kind of rail traffic platform sliding door of screen door hermetically-sealed construction, be installed in the opposite flank of the left sliding door and the right sliding door doorframe of shield door, comprise two adhesive tape section bars and two sealing joint strips, two adhesive tape section bars are installed in respectively on the doorframe of left sliding door and right sliding door, two sealing joint strips are inlaid in respectively on two adhesive tape section bars, described two sealing joint strip symmetrical configuration are identical, the sealing surface both sides of sealing joint strip are respectively equipped with first seal convexity and second seal convexity, side at deflection first seal convexity in the middle of the sealing surface of sealing joint strip is provided with the 3rd seal convexity, between first seal convexity and the 3rd seal convexity, form first concave station, between second seal convexity and the 3rd seal convexity, form second concave station, first seal convexity is identical with the height of second seal convexity, and the height of the 3rd seal convexity is higher than the height of first seal convexity and second seal convexity.
Described two sealing joint strips are inlaid in respectively on two adhesive tape section bars according to the staggered mode of the 3rd seal convexity, when left sliding door and right sliding door are closed, two sealing joint strips coincide mutually and form sealing, and first seal convexity of a side seal adhesive tape and second seal convexity of opposite side sealing joint strip coincide mutually and form sealing, second seal convexity of one side seal adhesive tape and first seal convexity of opposite side sealing joint strip coincide mutually and form sealing, the 3rd seal convexity of one side seal adhesive tape and second concave station of opposite side sealing joint strip coincide mutually and form sealing, and second concave station of a side seal adhesive tape and the 3rd seal convexity of opposite side sealing joint strip coincide mutually and form sealing.
Described first seal convexity, second seal convexity and the 3rd seal convexity have compressible hollow-core construction respectively.
Adopt structure of the present utility model, opening at closing time when sliding door, left and right sealing joint strip moves with regard to the following left sliding door.When having the passenger to enter train in the process of closing the door, shield door can be opened automatically when contacting left and right doorframe, opens the back and attempts closing the door for the second time.A buffer protection function is arranged when the passenger contacts the adhesive tape that is installed on the left and right doorframe, can not make the passenger be clamped or crush by left and right doorframe.After sliding door was closed, structure of the present utility model formed sealing fully between left and right sliding door, had avoided loss cold in the platform, heating installation, and the overall appearance to shield door has also played certain effect of interspersing simultaneously.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model rail traffic platform sliding door of screen door hermetically-sealed construction;
Fig. 2 is the cross section structure schematic diagram of the sealing joint strip in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, Fig. 2, rail traffic platform sliding door of screen door hermetically-sealed construction of the present utility model, be installed in the opposite flank of the doorframe 11,21 of the left sliding door 1 of shield door and right sliding door 2, comprise two adhesive tape section bars 3 and two sealing joint strips 4, two adhesive tape section bars 3 are installed on the doorframe 11,21 of left sliding door and right sliding door by screw 5 respectively, and two sealing joint strips 4 are inlaid in respectively on two adhesive tape section bars 3.
Cooperation is referring to Fig. 2, two sealing joint strip 4 symmetrical configuration in the utility model are identical, the sealing surface both sides of sealing joint strip are respectively equipped with first seal convexity 41 and second seal convexity 42, side at deflection first seal convexity 41 in the middle of the sealing surface of sealing joint strip is provided with the 3rd seal convexity 43, between first seal convexity 41 and the 3rd seal convexity 43, form first concave station 44, between second seal convexity 42 and the 3rd seal convexity 43, form second concave station 45, first seal convexity 41 is identical with the height of second seal convexity 42, and the height of the 3rd seal convexity 43 is higher than the height of first seal convexity 41 and second seal convexity 42.
