Description

Technical Field

[0001] This utility model relates to the field of air shower door technology, and in particular to a sealing strip. Background Technology

[0002] Air shower door sealing strips are used to seal between the air shower door frame and the door to prevent dust and pollutants from entering the clean area. With the increasing requirements for cleanroom environment, traditional sealing methods are difficult to meet the needs of efficient sealing and durability. Air shower door sealing strips are usually made of high-performance rubber, silicone and other materials, which have good elasticity, wear resistance and corrosion resistance, and can effectively maintain the air cleanliness and airflow stability of the cleanroom.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing sealing strips cannot be adjusted or added to provide a stable sealing effect. The main function of the air shower is to blow away dust from the surface of personnel or goods entering the room through high-speed clean airflow to maintain the cleanliness of the room. If the air shower door sealing strip cannot be effectively sealed, outside air and dust will easily enter the air shower room, leading to a decrease in the cleanliness of the room. If the air shower door is not properly sealed between adjacent clean rooms, it may lead to poor air circulation or even negative pressure difference, thereby causing cross-contamination. This cross-contamination will not only affect product quality but may also cause serious pollution to the production environment.

[0004] Therefore, this utility model proposes a sealing strip to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-4 As shown, this embodiment provides a technical solution: a sealing strip, comprising:

[0034] The first sealing strip 1 and the second sealing strip 2 disposed on the first sealing strip 1;

[0035] The connecting component 3 is placed on the first sealing strip 1. The connecting component 3 includes a limiting plate 31 fixed on the first sealing strip 1, a first limiting block 32 fixedly connected to the first sealing strip 1, a first limiting groove 33 opened on the first limiting block 32, a second limiting block 34 disposed in the first limiting groove 33, the second limiting block 34 fixedly connected to the second sealing strip 2, a second limiting groove 35 opened on the side of the second sealing strip 2 near the limiting plate 31, and the limiting plate 31 disposed in the second limiting groove 35.

[0036] Mounting component 4 is placed at the bottom of the first sealing strip 1. Mounting component 4 includes a connecting strip 41 fixedly connected to the bottom of the first sealing strip 1. The bottom of the first sealing strip 1 has a through hole 42. Firstly, the first sealing strip 1, as the main sealing component, is connected to the second sealing strip 2 via the connecting component 3. The connecting component 3 includes a limiting plate 31, which is fixed to the first sealing strip 1 and connected to the second limiting block 34 via a first limiting block 32. The first limiting groove 33 on the first limiting block 32 engages with the second limiting block 34 to ensure the second sealing strip 2 is in the correct position. The second sealing strip 2 is then connected via its first limiting groove 33. The two limiting grooves 35 are fixed in conjunction with the limiting plate 31, so that the first sealing strip 1 and the second sealing strip 2 can be tightly connected to ensure the sealing effect of the air shower door. This allows the sealing strips to be adjusted and added to provide a stable sealing effect. In addition, the mounting component 4 is located at the bottom of the first sealing strip 1 and is fixed to the bottom of the first sealing strip 1 by the connecting strip 41. The bottom is provided with a through hole 42, which makes the installation of the first sealing strip 1 more stable and allows air at the installation location to be smoothly discharged through the through hole 42, improving the stability and durability of the first sealing strip 1, while ensuring that the sealing performance is not compromised during long-term use.

[0037] The above solutions also have the problem that if a second sealing strip 2 needs to be installed on the first sealing strip 1, it cannot effectively limit and fix the second sealing strip 2.

The bottom of the retaining pin 38 is equipped with a pin head 39. The design of the pin head 39 not only improves the fixing effect of the retaining pin 38, but also enhances the long-term stability, durability, and reliability of the sealing system.

[0038] Working principle: such as Figures 1-4As shown, firstly, the first sealing strip 1, as the main sealing component, is connected to the second sealing strip 2 via the connecting assembly 3. The connecting assembly 3 includes a limiting plate 31, which is fixed to the first sealing strip 1 and connected to the second limiting block 34 via a first limiting block 32. The first limiting groove 33 on the first limiting block 32 engages with the second limiting block 34 to ensure the second sealing strip 2 is in the correct position. The second sealing strip 2 is fixed by its second limiting groove 35 cooperating with the limiting plate 31. The retaining plate 36 is set in the retaining groove 37, which not only improves the fixation and sealing performance between the first sealing strip 1 and the second sealing strip 2, but also effectively improves the safety, durability, and ease of maintenance of the system. The main function of the retaining pin 38 is to provide additional fixing force to ensure that the second sealing strip 2 can be stably fixed to the first sealing strip 1, avoiding... To prevent the second sealing strip 2 from loosening or falling off due to external forces, pressure changes, or vibrations during operation, the design of the nail head 39 not only improves the fixing effect of the clip 38, but also enhances the long-term stability, durability, and reliability of the sealing system. This allows the first sealing strip 1 and the second sealing strip 2 to be tightly connected, ensuring the sealing effect of the air shower door. The sealing strip can be adjusted and added to provide a stable sealing effect. In addition, the mounting component 4 is located at the bottom of the first sealing strip 1 and is fixed to the bottom of the first sealing strip 1 by the connecting strip 41. The bottom is provided with a through hole 42, which makes the installation of the first sealing strip 1 more secure and allows air at the installation location to be smoothly discharged through the through hole 42, improving the stability and durability of the first sealing strip 1, while ensuring that the sealing performance is not compromised during long-term use.
