Abstract

The utility model discloses a bottom self-sealing door which comprises a door frame and a door leaf. A hinge edge of the door leaf is connected with the door frame through hinges. A left right-angled connecting bar and a right right-angled connecting bar disposed in parallel are rotatably disposed in the door leaf through pins. A horizontal push bar is connected to the tops of the two right-angled connecting bars through pins. A return spring with one end abutted to the horizontal push bar and other end abutted to the door leaf is sleeved on a body of the horizontal push bar. A horizontal contact is disposed at one end of the horizontal push bar. When the return spring is free, the horizontal contact extends out of the hinge edge of the door leaf, the bottoms of the two right-angled connecting bars are connected with a square seal tube through perpendicular suspending bars, and a rubber seal strip is disposed at the bottom of the square seal tube. The bottom self-sealing door is simple in structure and convenient to use, and the gap between the bottom of the door leaf and the ground can be sealed effectively.

Description

The bottom is hermatic door automatically

Technical field

The utility model relates to a kind of door

Background technology

In the prior art; The encapsulating method of door all is between doorframe and door leaf, to add the ring-shaped rubber weather strip, yet some door does not allow door; And the inside and outside ground of door does not allow the discrepancy in elevation again; So, traditional encapsulating method just can only seal up three faces (two sides and an end face) of door, and the gap between door leaf bottom surface and the ground just can't seal with conventional method

Summary of the invention

the utility model purpose is: provide a kind of bottom automatic hermatic door, it is simple in structure, easy to use, can effectively seal up the gap between door leaf bottom surface and the ground.

The technical scheme of the utility model is: the automatic hermatic door in a kind of bottom; Comprise doorframe and door leaf; The hinged limit of said door leaf links to each other with doorframe through hinge, and the inside of said door leaf is rotatably mounted about two through bearing pin and the right angle connecting rod of column distribution, and the top of these two right angle connecting rods is through bearing pin connection horizontal push; Be with on the body of rod of horizontal push that an end is against on the horizontal push, the other end is against the back-moving spring on the door leaf; Level contacts is equipped with in one end of horizontal push, and when back-moving spring was in free state, said level contacts was stretched out outside the hinged limit of door leaf; The bottom of said two right angle connecting rods connects the sealing square tube through vertical suspension rod, and sealing joint strip is equipped with in the bottom of sealing square tube.

said back-moving spring is a stage clip.

the utility model has the advantages that: the utility model bottom is the sealing mechanism and the switch door action interlock of hermatic door automatically, the i.e. sealing of closing the door, and the i.e. unpacking of opening the door, very convenient.Specific as follows:

are when hermatic door is in opening, because the effect of back-moving spring is stretched out outside the hinged limit of door leaf level contacts, the sealing square tube is in a high position with sealing joint strip and does not contact with ground; When this hermatic door was in closed condition, doorframe can compress level contacts and level contacts is pressed in the door leaf, sealed square tube and sealing joint strip simultaneously and can move down and be in low level, thereby the gap sealing between door leaf bottom surface and the ground is lived.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the structural representation (being in the sectional view under the closed condition) of the utility model embodiment;

Fig. 2 is that the A-A of Fig. 1 is to sectional view;

wherein: the 1-doorframe, and the 2-door leaf, 3-right angle connecting rod, the 4-horizontal push, the 5-level contacts, the 6-back-moving spring, the vertical suspension rod of 7-, 8-seals square tube, 9-sealing joint strip, 10-ground, 11-door leaf lower frame.

The specific embodiment

are as depicted in figs. 1 and 2, and the automatic hermatic door in the bottom of present embodiment comprises doorframe 1 and door leaf 2, and the hinged limit of said door leaf 2 links to each other with doorframe 1 through the hinge (not shown).

The inside of said door leaf 2 is equipped with about two and the right angle connecting rod 3 of column distribution, and each right angle connecting rod 3 all is installed in rotation on the inside of door leaf 2 through bearing pin.The top of these two right angle connecting rods 3 connects a horizontal push 4 through bearing pin, is with back-moving spring 6 (stage clip) on the body of rod of horizontal push 4, and an end of this back-moving spring 6 is against on the horizontal push 4, the other end is against on the door leaf 2.Level contacts 5 is equipped with in one end of horizontal push.The bottom of said two right angle connecting rods 3 connects a sealing square tube 8 through vertical suspension rod 7, and sealing joint strip 9 is equipped with in the bottom of sealing square tube 8, and sealing square tube 8 all is positioned at door leaf 2 bottoms with sealing joint strip 9.

The operating principle of present embodiment is: when this hermatic door was opened, back-moving spring 6 was in free extended configuration, and level contacts 5 is stretched out outside the hinged limit of door leaf 2, and sealing square tube 8 is in a high position with sealing joint strip 9 and does not contact with bottom surface 10; When this hermatic door is closed; Level contacts 5 can be inconsistent with doorframe 2; Doorframe 2 compresses level contacts 5 and makes level contacts be pressed into door leaf 2 inside; And then corresponding action (this moment, back-moving spring was in compressive state) take place in drive horizontal push 4, back-moving spring 6, vertical suspension rod 7, sealing square tube 8 and sealing joint strip 9; Sealing square tube 8 and sealing joint strip 9 can move down and be in low level; (when this hermatic door changed opening over to by closed condition, sealing square tube and sealing joint strip can move upward again and be in a high position, and can be with door leaf lower frame 11 as sealing the guide (like Fig. 2) that square tube and sealing joint strip move up and down thereby the gap closing between door leaf bottom surface and the ground is lived.

are certain, and the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is the content that lets people can understand the utility model and implements according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model
