In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a freezer door strip of paper used for sealing, includes footstock and air chamber, the footstock bottom is equipped with fixed foot, fixed foot links to each other with the air chamber top, and encloses into side direction open-ended U-shaped groove with the roof of air chamber, U-shaped inslot portion is equipped with a plurality of crisscross zigzag anti-overflow muscle, and the air chamber comprises upper portion brace rod, buffering gasbag, lower part buffering muscle and outer wall all around, the buffering gasbag is oval, lower part buffering muscle is the ingot shape, and the exocoel wall of the air chamber laminating cabinet body is equipped with the sealed wing that extends to the door liner direction, one side chamber wall of door liner is pressed close to the air chamber still is equipped with supplementary.

Furthermore, a plurality of reinforcing ribs are arranged in the outer cavity wall of the air chamber.

Furthermore, the upper supporting rib adopts a trapezoidal design, and the top of the trapezoid is connected with the buffering air bag.

Further, the anti-overflow rib faces the bottom of the U-shaped groove.

The utility model has the advantages as follows:

1. when the door body is closed and the door seal is pressed, the trapezoidal upper supporting rib, the oval buffer air bag and the ingot-shaped lower buffer rib are arranged in the air chamber to form at least five closed air bags, the multi-air-bag structure not only can play a role in buffering in the opening and closing process of the door body, but also increases the temperature gradient inside and outside the refrigerator, reduces the heat convection and heat conduction rate, and therefore, the energy consumption of the refrigerator can be effectively reduced.

2. Through being equipped with trapezoidal upper portion brace rod and "ingot" shape lower part buffering muscle in that the air chamber is inside, play the joint support effect, can guarantee when the freezer is closed the door, support the door strip of paper used for sealing and be unlikely to by the flat of cabinet door pressure, and when the freezer opens the door, support the quick reconversion of door strip of paper used for sealing.

3. Through set up a plurality of strengthening ribs in the outer cavity wall of air chamber, increase the intensity in door strip of paper used for sealing outside chamber wall, can solve the bight fracture problem well.

4. Through setting up outside supplementary gasbag and sealed wing, both combined action increase the laminating degree between door seal and the door lining, widen the width of door strip of paper used for sealing, prevent that the freezer from carrying out inside and outside heat exchange when closed, solve the middle easy ejecting cabinet mouth department that causes of foaming of door seal and leak cold problem.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application.

The first embodiment is as follows:

the utility model provides a freezer door strip of paper used for sealing, includes footstock 1 and air chamber 2, 1 bottom of footstock is equipped with fixed foot 11, fixed foot 11 links to each other with 2 tops of air chamber, and encloses into side direction open-ended U-shaped groove 12 with the roof of air chamber 2, and door lining 3 inserts in the U-shaped groove 12 when the assembly to realize the strip of paper used for sealing and 3 fixed mounting of door lining. The U-shaped groove 12 is internally provided with a plurality of staggered zigzag anti-overflow ribs 13, the anti-overflow ribs 13 face to the bottom of the U-shaped groove, namely the orientation of the anti-overflow ribs 13 is opposite to the flowing direction of foaming materials when overflowing, so that the problem of cold leakage in the middle of a door seal caused by the fact that a door body is wasted due to the fact that a foamed door seal slides or the overflowing materials leak can be reduced.

The air chamber 2 is composed of an upper supporting rib 21, a buffer air bag 22, a lower buffer rib 23 and peripheral outer walls. The upper supporting rib 21 adopts a trapezoidal design, has a stable structure, is convenient for punching air holes, and can prevent the problem of overhigh negative pressure in the air chamber. The lower buffer rib 23 is designed in a shape of a ingot, the two sides are high and the middle is low, so that the oval buffer air bag 22 can be better attached, and the strength of the door seal can be increased while the support performance is achieved. The lower buffer rib 23 and the upper support rib 21 act together, so that when the refrigerator is closed, the support door seal strip is not shrunken by the door of the refrigerator, and when the refrigerator is opened, the support door seal strip is quickly restored. When the door body is closed, the door seal strip is pressed, the upper supporting rib 21, the buffering air bag 22 and the lower buffering rib 23 of the air chamber 2 form at least five closed air bags, and the multi-air-bag structure formed inside not only can play a role in buffering in the opening and closing process of the door body, but also increases the temperature gradient inside and outside the refrigerator, reduces the heat convection and heat conduction rate, and therefore, the energy consumption of the refrigerator can be effectively reduced. The outer cavity wall of the air chamber 2 is internally provided with a plurality of reinforcing ribs 24, so that the strength of the outer side cavity wall of the door seal strip is enhanced, and the problem of corner cracking can be well solved. The sealing fins 25 extending towards the door liner 3 are arranged on the outer cavity wall of the air chamber 2 attached to the cabinet body 4, so that gaps at the connecting part between the door seal and the door liner are effectively covered, and the problem of cold leakage at the cabinet opening caused by easy ejection of the middle part when the door seal is foamed is solved. The chamber wall of one side that air chamber 2 is pressed close to door liner 3 still is equipped with supplementary gasbag 26 outward, when playing the auxiliary stay effect, widens the width of door strip of paper used for sealing, and with sealed wing 25 interact, prevent that the freezer from carrying out inside and outside heat exchange when closed, further increase the heat preservation ability of door strip of paper used for sealing.

The utility model discloses in the door seals for materials such as soft polyvinyl chloride (PVC) elastomer, polyolefin thermoplastic elastomer (TPE), silicon rubber, and the material is safe, meets the requirements.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
