Terms used herein, including technical and scientific terms, have the same meaning as terms commonly understood by one of ordinary skill in the art, unless otherwise defined. It will be understood that terms defined in commonly used dictionaries have meanings that are consistent with their meanings in the prior art.
Referring to fig. 1 to 4, a door bottom sealing structure of an indoor door includes a sealing frame 2 fixedly disposed in a sealing strip mounting groove 1; the sealing strip mounting groove 1 is arranged at the bottom of the door leaf 3; the door leaf is connected with the door frame 5 through a hardware connecting piece 4; a bulge part 6 is arranged on the inner side of the door frame; an elastic switch 7 is arranged at one end of the sealing frame close to the protruding part; the bottom of the sealing frame is provided with a sealing strip body 8; the elastic switch is contacted with or separated from the bulge part, and the lifting of the sealing strip body is controlled by the reciprocating mechanism.
Specifically, in this embodiment, door leaf 3 is closing the in-process, and elastic switch 7 can take place the extrusion with bellying 6 on the door frame, and elastic switch 7 produces the displacement owing to receive the extruded reason, and then takes place the linkage through reciprocating mechanism and sealing strip body for the sealing strip body descends when the door leaf is closed, with the laminating on ground, improves the door leaf leakproofness.
After the door leaf is opened, pressure disappears, and elastic switch 7 resets, and then shifts up through reciprocating mechanism control sealing strip, takes in the sealing frame, like this at the door leaf motion in-process, can not receive the resistance that sealing strip body and ground friction produced, realizes that the switch of the door body is smooth and easy.
Further, the sealing strip mounting groove 1 is a square groove; the sealing strip mounting groove 1 is arranged at the bottom of the door leaf 3 in a penetrating manner; the length of the sealing frame 2 is the same as that of the sealing strip mounting groove; and two ends of the sealing strip mounting groove are respectively provided with a packaging sheet 9.
Specifically, in the present embodiment, the sealing frame 2 is fixedly connected to prevent the sealing frame from being mounted in the sealing strip mounting groove, and the sealing strip body 8 is actually fixedly connected to the reciprocating mechanism, and the reciprocating mechanism drives the sealing strip body to ascend and descend.
Furthermore, a through hole 9.1 for the elastic switch 7 to pass through is formed on the packaging sheet 9 at one end close to the protruding part; the packaging piece is fixedly connected with the door leaf through a screw.
Specifically, in this embodiment, an iron piece having a certain thickness may be used as the protrusion, and in other embodiments, a part having another shape or texture may be used as the protrusion as long as it can protrude from the door frame.
Furthermore, the convex part is an iron sheet; the convex part is fixedly connected with the door frame through a screw; the protruding part is positioned at the right lower side of the hardware connecting piece.
Furthermore, the sealing frame 2 is provided with a mounting chamber 2.1 relative to the elastic switch; the elastic switch comprises a cylindrical rod 7.1 and a spring 7.2; the reciprocating mechanism comprises an ejection part connected with the cylindrical rod 7.1; the upper side of the sealing strip body is connected into the sealing frame through a spring.
Furthermore, a limiting ring 7.3 is arranged on the cylindrical rod 7.1; the spring 7.2 is sleeved outside the cylindrical rod, and two ends of the spring are respectively connected to the limiting ring and the inner side wall of the mounting cavity.
Specifically, in this embodiment, the elastic switch is composed of the cylindrical rod 7.1, the spring 7.2 and the limit ring integrally arranged with the cylindrical rod 7.1, when the cylindrical rod 7.1 is extruded by the protruding portion, the spring is compressed, so that the whole cylindrical rod 7.1 moves towards the installation cavity (the reciprocating mechanism is linked in the moving process), and when the external force disappears, the limit ring 7.3 is pushed outwards due to the acting force of the spring, so that the cylindrical rod resets.
Further, the ejection portion includes a first link 10 and a second link 11.
Furthermore, one end of the first connecting rod 10 is hinged to the cylindrical rod 7.1, and the other end of the first connecting rod is hinged to the second connecting rod 11; the tail end of the second connecting rod 11 is contacted with or separated from the upper side of the sealing strip body.
