[0021] According to this specific embodiment, the chamfered corner is fixedly connected to the annular band 101 and is located on one side of the annular band 101. The lip 103 is fixedly connected to the annular band 101 and is located above the inside of the annular band 101. The placement groove 104 is fixedly connected to the annular band 101 and is located above the inside of the annular band 101. The placement groove 104 is also provided on one side of the lip 103. The negative pressure groove 105 is fixedly connected to the annular band 101 and is located above the inside of the annular band 101. The negative pressure groove 105 is provided on the side of the lip 103 away from the placement groove 104. When sealing the vehicle door and the vehicle body, the staff will use the placement groove 104 to place the annular band 101 on the vehicle body. After the lip 103 and the negative pressure groove 105 are installed, a certain negative pressure or vacuum state will be formed in the internal space of the negative pressure groove 105 after installation, thereby enhancing the installation firmness of the annular band 101.

[0022] Among them, the upper buffer hole 106 is fixedly connected to the annular belt 101 and is located above the inside of the annular belt 101, and the upper buffer hole 106 is arranged below the placement groove 104, and the upper buffer hole 106 is arranged vertically to the lip edge 103. After the deformation hole 109 is impacted for the first time, the remaining impact force will be buffered by the upper buffer hole 106 and the lower buffer hole 107.

[0023] Secondly, the lower buffer hole 107 is fixedly connected to the annular belt 101 and is located below the inside of the annular belt 101, and the lower buffer hole 107 is arranged below the upper buffer hole 106. The rebound strip 108 is fixedly connected to the annular belt 101 and is located inside the annular belt 101, and the rebound strip 108 is arranged inside the lower buffer hole 107. Since the connection points of the car doors are mostly terraced, the lower buffer hole 107 needs to receive more impact force than the upper buffer hole 106. After the lower buffer hole 107 receives the impact, the rebound strip 108 will cooperate with the lower buffer hole 107 to alleviate the impact force.

[0024] At the same time, the deformation hole 109 is fixedly connected to the annular belt 101 and is located on one side of the interior of the annular belt 101, and the deformation hole 109 is arranged on one side of the upper buffer hole 106 and the lower buffer hole 107. The deformation hole 109 is also arranged below the negative pressure groove 105. The rebound column 110 is fixedly connected to the annular belt 101 and is located inside the annular belt 101, and the rebound column 110 is arranged inside the deformation hole 109. The rebound column 110 is also arranged vertically with the deformation hole 109. When the car door is closed forcefully, causing the car door to collide strongly with the annular strip, the deformation hole 109 will be impacted first. Since the deformation hole 109 is elliptical, the impact force caused by the collision will be greatly alleviated during the deformation process. After deformation, the deformation hole 109 will rebound by the rebound column 110, thereby returning to its original shape.

[0025] In addition, the sound insulation hole 111 is fixedly connected to the annular belt 101 and is located on the inner side of the annular belt 101, and the sound insulation hole 111 is arranged on the side of the upper buffer hole 106 and the lower buffer hole 107 away from the deformation hole 109. The sound insulation hole 111 is also arranged below the negative pressure groove 105. When the car door collides with the annular belt 101, a certain amount of noise will inevitably be generated, and the sound insulation hole 111 in the annular belt 101 will effectively prevent the noise from being transmitted into the interior of the car body, thereby providing users with a better experience of sound insulation.

[0026] Among them, the safety identification belt 112 is detachably connected to the annular belt 101 and is located below the inside of the annular belt 101, and the safety identification belt 112 is arranged below the lower buffer hole 107. After long-term use, the user can observe the status of the safety identification belt 112, and when the safety identification belt 112 is broken, the annular belt 101 needs to be replaced in time.

[0027] When the present invention is used to seal a car door and a car body, a worker will use the installation groove 104 to install the annular belt 101 on the car body. After the lip 103 and the negative pressure groove 105 are installed, a certain negative pressure or vacuum state will be formed in the internal space of the negative pressure groove 105 after installation, thereby strengthening the installation firmness of the annular belt 101. When the car door is closed vigorously, resulting in a strong collision between the car door and the annular strip, the deformation hole 109 will be impacted first. Since the deformation hole 109 is elliptical, the impact force caused by the collision will be greatly alleviated during the deformation process. After deformation, the deformation hole 109 will rebound by the rebound column 110 to return to its original shape, and the remaining impact force will be buffered by the upper buffer hole 106 and the lower buffer hole 107. At the same time, since the connection points of the car doors are mostly terraced, the lower buffer hole 107 is smaller than the upper buffer hole The punching hole 106 needs to receive more impact force, and after the lower buffer hole 107 receives the impact, the rebound strip 108 will cooperate with the lower buffer hole 107 to alleviate the impact force. When the car door collides with the annular belt 101, a certain amount of noise will inevitably be generated, and the sound insulation hole 111 in the annular belt 101 will effectively prevent the noise from entering the interior of the car body, thereby providing the sound insulation user with a better use experience. After long-term use, the user can observe the status of the safety identification belt 112, and when the safety identification belt 112 is broken, the annular belt 101 will need to be replaced in time. While retaining the original beneficial effects, it actively and effectively solves the situation where the car door is inevitably closed forcefully during long-term use. Under strong impact, the probability of the small lip being damaged increases sharply, and after the small lip is damaged, it will not be able to reduce the noise and cannot provide effective sealing between the car door and the car body, posing a safety hazard.
