Description

Technical Field

[0001] This application relates to the field of sealing strip technology, and more particularly to a sealing strip for cold storage doors. Background Technology

[0002] Cold storage sealing strips are mainly used to seal cold storage doors, preventing cold air leakage and ensuring a stable internal environment. Because cold storage doors are frequently opened and closed, the area where the door frame contacts the ground is prone to frost or freezing due to temperature fluctuations. Sealing strips effectively prevent this, avoiding the problem of frozen door frames causing difficulty in opening and closing.

[0003] The cold storage door sealing strip consists of two parts: one part is installed at the edge of the cold storage door opening, and the other part is installed on the cold storage door itself. The two parts work together to achieve a sealing effect. However, current cold storage door sealing strips still have certain drawbacks during installation and use. Due to repeated opening and closing of the door over long-term use, the sealing strip is subject to temperature fluctuations, making it prone to mold growth during rainy seasons. Furthermore, it accumulates dust over time, and existing sealing strips are not easy to disassemble and clean. Without cleaning, bacteria can grow, affecting the hygiene of the cold storage. Therefore, this application proposes a new type of cold storage door sealing strip. Utility Model Content

[0004] The purpose of this application is to address the technical problems pointed out in the background art by proposing a sealing strip for cold storage doors.

[0005] The technical solution of this application: A cold storage door sealing strip, including two connecting strips, and further comprising:

[0006] A sealing groove is formed on the side wall of one of the connecting strips, and a sealing strip is fixedly connected to the side wall of the other connecting strip. When the cold storage door is closed, the sealing strip fits into the sealing groove.

[0007] Both sides of the two connecting strips are fixedly connected with built-in positioning components;

[0008] The built-in positioning component includes a support bar fixedly connected to the side of the connecting bar, and a support airbag is connected to one end of the support bar. The cross-section of the support airbag after it is inflated is larger than the cross-section of the support bar.

[0009] Preferably, one of the connecting strips has a pair of rectangular grooves on its sidewall, which are located on both sides of the sealing groove, and the other connecting strip has a pair of rectangular strips fixedly connected to its sidewall, which are located on both sides of the sealing strip. When the cold storage door is closed, the two rectangular strips are inserted into the two rectangular grooves respectively.

[0010] Preferably, the inner end of the supporting airbag is fixedly connected to an inflation tube that extends into the rectangular groove, and a first one-way valve is provided inside the inflation tube.

[0011] The inner end of the support airbag is also connected to a vent pipe that extends into the rectangular groove, and a second one-way valve is installed in the vent pipe.

[0012] Preferably, the side of the supporting airbag near the connecting strip is fixedly connected with auxiliary support plates located on both sides of the supporting strip for support and positioning.

[0013] Preferably, each of the two connecting strips has a groove at one end that is far from each other, and a magnetic strip is embedded in each of the two grooves. The magnetic strip can be attached to the cold storage or the cold storage door.

[0014] Preferably, the sealing groove is slightly larger than a half-circular arc groove, the sealing strip is slightly larger than a half-circular arc shape, and the sealing strip is elastic.

[0015] Compared with the prior art, this application has the following beneficial technical effects:

[0016] This application features built-in positioning components on both sides of the connecting strip, and corresponding T-shaped connecting grooves on both the cold storage and the cold storage door. The supporting airbag can be inflated or deflated. When the sealing strip needs to be disassembled and cleaned, the one-way valve on the vent pipe is opened, and then the connecting strip is taken out. During the removal process, the supporting airbag and the T-shaped groove are squeezed together, causing the gas inside to be discharged, thus making it easy to remove the connecting strip for cleaning and maintaining a good hygienic condition.

[0017] By creating a sealing groove on the outer surface of one of the connecting strips and fixing a sealing strip to the outer surface of the other connecting strip, the sealing strip fits into the sealing groove when the cold storage door is closed, achieving a better sealing effect and further preventing cold air leakage inside the cold storage.

[0018] By embedding magnetic strips at the ends of the two connecting strips that are far apart from each other, the two magnetic strips attract the cold storage and the cold storage door respectively when in use, which further improves the stability of the connecting strip connection.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Example

[0029] like Figures 1-3 As shown, the cold storage door sealing strip proposed in this application includes two connecting strips 1 and a sealing groove 6 formed on the side wall of one of the connecting strips 1. A sealing strip 8 is fixedly connected to the side wall of the other connecting strip 1. When the cold storage door is closed, the sealing strip 8 fits into the sealing groove 6, which can achieve a better sealing effect when the cold storage door is closed, and further prevent cold air leakage.

[0030] Each of the two connecting strips 1 has a built-in positioning component 2 fixedly connected to both sides, which facilitates the disassembly and assembly of the two connecting strips 1.

[0031] Specifically, the built-in positioning component 2 includes a support strip 21 fixedly connected to the side of the connecting strip 1. One end of the support strip 21 is connected to a support airbag 22. The cross-section of the inflated support airbag 22 is larger than that of the support strip 21. T-shaped connecting grooves are provided on both the cold storage door and the cold storage. The inflated support airbag 22 can fill the inner side of the T-shaped groove. The side of the support airbag 22 near the connecting strip 1 is fixedly connected to auxiliary support plates 23 located on both sides of the support strip 21 for support and positioning (when the support airbag 22 is inflated, the two auxiliary support plates 23 are perpendicular to the support strip 21).

[0032] Specifically, one of the connecting strips 1 has a pair of rectangular grooves 7 located on both sides of the sealing groove 6 on its side wall, and the other connecting strip 1 has a pair of rectangular strips 9 located on both sides of the sealing strip 8 fixedly connected to its side wall. When the cold storage door is closed, the two rectangular strips 9 are inserted into the two rectangular grooves 7 respectively. The inner end of the supporting airbag 22 is fixedly connected to an inflation pipe 4 that extends into the rectangular groove 7. The inflation pipe 4 is equipped with a first one-way valve. After the first one-way valve is opened, gas can be injected into the supporting airbag 22 (there will be no leakage during the inflation process, and there will be no leakage when the external inflation pipe is removed). The inner end of the supporting airbag 22 is also connected to a venting pipe 5 that extends into the rectangular groove 7. The venting pipe 5 is equipped with a second one-way valve. When it is necessary to disassemble and clean the sealing strip, the second one-way valve in each rectangular groove 7 is opened to release the gas in both pairs of supporting airbags 22, allowing the two connecting strips 1 to be easily and without damage.

[0033] Furthermore, each of the two connecting strips 1 has a groove at one end that is far apart from each other, and a magnetic strip 3 is embedded in each of the two grooves. The magnetic strip 3 can be attached to the cold storage or the cold storage door, which can improve the stability of the installation of the two connecting strips 1.

[0034] In this embodiment, the sealing groove 6 is slightly larger than a half-circular arc groove, and the sealing strip 8 is slightly larger than a half-circular arc shape, and the sealing strip 8 is elastic. When the sealing strip 8 is inserted into the sealing groove 6, the covering area is larger, and the sealing performance is better.

[0035] In practical use: First, insert the two connecting strips 1 into the T-shaped connecting grooves of the cold storage door and the cold storage. During installation, both pairs of support airbags 22 are in a deflated state. When the support airbags 22 are located in the inner groove of the T-shaped groove, insert the external inflation tube into the inflation tube 4 to inflate the support airbags 22, causing them to bulge. After the support airbags 22 bulge, they fit snugly into the inner groove of the T-shaped groove. At this time, the two auxiliary support plates 23 are respectively supported and located at both ends of the support strip 21, thus achieving a better support and positioning effect. Furthermore, when the connecting strip 1 is inserted into the T-shaped groove, the magnetic strip 3 is attracted to the cold storage door or cold storage, making the connection of the connecting strip 1 more stable.

[0036] When the sealing strip needs to be disassembled and cleaned, open the one-way valve on the vent pipe 5, and then take out the connecting strip 1. During the removal process, the supporting airbag 22 and the T-slot will squeeze the gas inside the connecting strip 1, so that the connecting strip 1 can be easily removed for cleaning, maintaining good hygiene and preventing bacteria from growing on the sealing strip.

[0037] By creating a sealing groove 6 on the outer surface of one of the connecting strips 1, the sealing groove 6 being slightly larger than half a circular arc groove, and fixing a sealing strip 8, also slightly larger than half a circular arc, to the outer surface of the other connecting strip 1, the sealing strip 8 fits snugly into the sealing groove 6 when the cold storage door is closed, achieving a better sealing effect and further preventing cold air leakage from the cold storage. Because the sealing strip 8 has a certain degree of elasticity, it can smoothly engage with the sealing groove 6 when opening and closing the cold storage door, and can also easily disengage from the sealing groove 6, making it economical and practical. In this application, the connecting strip 1 is made of rubber, which is flexible and has a certain degree of elasticity.

[0038] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
