Description

Technical Field

[0001] This utility model relates to the field of sealing strips, and in particular to a sealing strip for a watertight door. Background Technology

[0002] A watertight door is a door installed on a watertight bulkhead, meeting watertight requirements and capable of preventing water infiltration. Watertight doors are widely used in various locations requiring waterproofing, moisture protection, and emergency protection, such as ships and docks, to prevent seawater or other liquids from entering the cabin and protect the vessel's safety. The sealing strip of a watertight door is a crucial component, essential for ensuring its airtightness and waterproofing.

[0003] While existing watertight doors use a variety of sealing strips, these strips have simple structures. After installation, they lack cushioning and anti-collision properties during closing. Repeated opening and closing of the watertight door can easily damage the sealing strips, affecting the overall sealing and waterproofing performance. Furthermore, the poor cushioning and anti-collision effect of the sealing strips during closing can cause them to loosen due to vibrations, further compromising waterproofing and sealing. Overall, their performance is generally mediocre. Utility Model Content

[0004] The main objective of this invention is to provide a sealing strip for a watertight door, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A sealing strip for a watertight door includes a fixed mounting strip with a connecting sleeve on the fixed mounting strip. A buffer anti-collision structure is installed at the front end of the connecting sleeve. The buffer anti-collision structure includes a sealing anti-collision strip, a deformation hole, a deformation support plate, and a wear-resistant outer layer. The deformation hole is formed on the sealing anti-collision strip, the deformation support plate is installed in the deformation hole on the sealing anti-collision strip, and the wear-resistant outer layer is connected to the sealing anti-collision strip.

[0007] Preferably, the fixing strip has a through hole, and the fixing strip and the connecting sleeve are integrally formed.

[0008] Preferably, the connecting sleeve has a square hole, and a cross support frame is fixedly installed in the square hole of the connecting sleeve. The cross support frame divides the square hole into filling holes of the same size, and filling strips are installed in the filling holes.

[0009] Preferably, the buffer anti-collision structure further includes round holes and sealing films, the deformation support plates are symmetrically distributed in the deformation holes on the sealing anti-collision strip, and the deformation support plates are distributed with an increasing angle from the middle to both ends inside the deformation holes.

[0010] Preferably, the circular hole is formed on the sealing anti-collision strip, the wear-resistant outer layer is fixedly connected to the sealing film, and the sealing film is symmetrically arranged on the wear-resistant outer layer, and the wear-resistant outer layer is fixedly connected to the sealing anti-collision strip.

[0011] Compared with the prior art, this utility model has the following beneficial effects: The sealing strip of the watertight door, through the set connecting sleeve, has a square hole on the connecting sleeve. The square hole is set with a cross support frame and a filling square strip. While ensuring the stability of the connection part, it improves the buffering effect of the connection part. The buffer anti-collision structure adopts a deformation support plate set in the deformation hole on the sealing anti-collision strip. The deformation support plate is distributed with an increasing tilt angle. It works in conjunction with the round hole. During the closing process of the watertight door, it can disperse the impact force and effectively play a buffering and anti-collision role, ensuring the integrity of the entire sealing strip. At the same time, the deformation support plate can also enhance the resilience of the sealing anti-collision strip, ensuring the sealing and waterproof performance of the watertight door after closing. The wear-resistant outer layer with sealing film on the sealing anti-collision strip can improve the wear resistance of the sealing strip, so that the sealing strip can be used for a long time.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-3As shown, a sealing strip for a watertight door includes a fixed mounting strip 1, a connecting sleeve 2 on the fixed mounting strip 1, and a buffer anti-collision structure 3 installed at the front end of the connecting sleeve 2. The fixed mounting strip 1 has a through hole 4, and the fixed mounting strip 1 and the connecting sleeve 2 are integrally formed. The connecting sleeve 2 has a square hole 5, and a cross support frame 6 is fixedly installed in the square hole 5. The cross support frame 6 divides the square hole 5 into filling holes of the same size, and a filling strip 7 is installed in the filling hole.

[0018] When using the sealing strip, during installation, the fixing strip 1 is connected to the door body. During this process, the fixing strip 1 deforms through the through hole 4, allowing it to quickly snap into the mounting groove on the door body. Once the sealing strip is installed, it is ready for use. During the closing of the watertight door, the buffer and anti-collision structure 3 provides cushioning and anti-collision, ensuring the integrity of the sealing strip. Simultaneously, the connecting sleeve 2, in conjunction with the cross support frame 6 inside the square hole 5, ensures the stability of the buffer and anti-collision structure 3. The filling strip 7 inside the square hole 5 can deform, allowing the connecting sleeve 2 to provide support while also undergoing elastic deformation, further enhancing the cushioning and anti-collision effect and ensuring the integrity of the sealing strip. After the watertight door is closed, the buffer and anti-collision structure 3, together with the connecting sleeve 2, provides the primary sealing and waterproofing, while the fixing strip 1 ensures the installation stability of the sealing strip. The structure is simple and the performance is excellent.

[0019] According to the above implementation scheme, the buffer anti-collision structure 3 includes a sealing anti-collision strip 301, deformation holes 302, deformation support plates 303, and a wear-resistant outer layer 305. The deformation holes 302 are formed on the sealing anti-collision strip 301, and the deformation support plates 303 are installed in the deformation holes 302 on the sealing anti-collision strip 301. The wear-resistant outer layer 305 is connected to the sealing anti-collision strip 301. The buffer anti-collision structure 3 also includes circular holes 304 and sealing sheets 306. The deformation support plates 303 are symmetrically distributed in the deformation holes 302 on the sealing anti-collision strip 301, and their distribution gradually increases in angle from the middle to both ends inside the deformation holes 302. The circular holes 304 are formed on the sealing anti-collision strip 301, and the wear-resistant outer layer 305 is fixedly connected to the sealing sheets 306. The sealing sheets 306 are symmetrically arranged on the wear-resistant outer layer 305, and the wear-resistant outer layer 305 is fixedly connected to the sealing anti-collision strip 301.

[0020] During the closing process of the watertight door, the wear-resistant outer layer 305 first contacts the door frame. Subsequently, after being obstructed, the wear-resistant outer layer 305 deforms along with the sealing anti-collision strip 301. During this process, under the action of the deformation support plate 303 and the round hole 304 inside the deformation hole 302, the sealing anti-collision strip 301 plays a buffering and anti-collision role. The deformation support plate 303, due to its gradually increasing tilt angle, works in conjunction with the round hole 304 to effectively disperse the impact force and ensure the integrity of the sealing strip. At the same time, the sealing film 306 at the wear-resistant outer layer 305 deforms after contacting the structure on the door frame. After the watertight door is closed, under the action of the round hole 304 and the deformation support plate 303, the sealing anti-collision strip 301 has good resilience, allowing the wear-resistant outer layer 305 to closely contact the door frame, improving waterproofness and sealing performance. The wear-resistant outer layer 305 has good wear resistance, ensuring that the sealing strip can be used for a long time.

[0021] It should be noted that the connecting sleeve 2 has a square hole 5, and a cross support frame 6 and a filling square strip 7 are installed inside the square hole 5. This improves the buffering effect of the connecting part while ensuring its stability. The buffer anti-collision structure 3 is adopted, and a deformation support plate 303 is installed in the deformation hole 302 on the sealing anti-collision strip 301. The deformation support plate 303 has a gradually increasing tilt angle and works in conjunction with the round hole 304. During the closing of the watertight door, it can disperse the impact force and effectively play a buffering and anti-collision role, ensuring the integrity of the entire sealing strip. At the same time, the deformation support plate 303 can also enhance the resilience of the sealing anti-collision strip 301, ensuring the sealing and waterproof performance of the watertight door after it is closed. The sealing anti-collision strip 301 is provided with a wear-resistant outer layer 305 with a sealing film 306, which can improve the wear resistance of the sealing strip and allow it to be used for a long time.

[0022] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
