Description

Technical Field

[0001] This utility model relates to the field of sealing structure technology, specifically an adaptive sealing structure. Background Technology

[0002] A sealing structure is an engineering device designed through mechanical, material, or fluid dynamics mechanisms to prevent leakage of media (gas, liquid, or solid particles) driven by pressure or temperature differences. Its core objective is to maintain stable pressure, temperature, and media purity or cleanliness inside and outside the system.

[0003] However, existing sealing structures lack self-adaptive capabilities. In actual use, thermal expansion and contraction can affect their sealing performance, leading to pipeline leaks. This results in significant limitations in their application. To address this issue, an adaptive sealing structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an adaptive sealing structure to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: an adaptive sealing structure, including a plug cylinder, a fixing plate fixedly sleeved on the outside of the plug cylinder, and "L"-shaped sealing gaskets connected to both sides of the fixing plate. The sealing gaskets are sleeved on the outside of the plug cylinder. Several springs are provided on both sides of the outer wall of the fixing plate. The other end of the springs is fixedly connected to the side of the sealing gasket parallel to the fixing plate. A rigid metal plate is fixedly embedded inside the side of the sealing gasket parallel to the fixing plate. The side of the sealing gasket perpendicular to the fixing plate is a flexible rubber gasket. Multiple fixing components are provided on the circumference of the outer wall of the plug cylinder.

[0005] Preferably, the fixing assembly includes a fixing cylinder, a lead screw, a knob, a telescopic assembly, and a top plate. The fixing cylinder is fixedly inserted into the insert cylinder, the lead screw is screwed into the inner cavity of the fixing cylinder, the knob is located at the bottom end of the lead screw, the top plate is rotatably connected to the top end of the lead screw via a bearing, and the telescopic assembly is fixedly inserted into the insert cylinder and fixedly connected to the top plate.

[0006] Preferably, the outer circumference of the knob is provided with anti-slip ridges.

[0007] Preferably, the outer wall of the top plate is adapted to fit the inner wall of the pipe.

[0008] Preferably, the telescopic assembly includes a telescopic cylinder, a telescopic rod, and a connecting assembly. The telescopic cylinder is fixedly inserted into the insert cylinder, the telescopic rod is slidably inserted into the inner cavity of the telescopic cylinder and fixedly connected to the top plate, and the connecting assembly is disposed in the inner cavity of the telescopic cylinder and fixedly connected to the outer wall of the telescopic rod.

[0009] Preferably, the connecting assembly includes a connecting groove and a connecting block. The connecting groove is formed on one side of the inner wall of the telescopic cylinder, and the connecting block is slidably embedded in the inner cavity of the connecting groove and fixedly connected to the outer wall of the telescopic rod.

[0010] Preferably, the inner cavity of the connecting groove and the outer wall of the connecting block are adapted to each other and are both dovetail-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. Since both L-shaped sealing gaskets are fixedly connected to the fixing plate, the two sealing gaskets and the fixing plate work together to seal the connection between the two pipes. Under the elastic force of the spring, the distance between the side of the sealing gasket parallel to the fixing plate and the fixing plate can be adjusted when the gap between the two pipes changes, thus keeping the two pipes sealed. This solves the problem that the existing sealing structure does not have self-adaptive ability, and the sealing performance is affected by thermal expansion and contraction during actual use, resulting in pipe leakage and limited use.

[0013] 2. By rotating the knob, the screw is driven to rotate. Since the screw is screwed into the inner cavity of the fixed cylinder, when the screw rotates, it can slide in the inner cavity of the fixed cylinder, thereby adjusting the position of the top plate. This allows multiple top plates to abut against the inner wall of the pipe, thus fixing the device. The device can be fixed on one side of the pipe, which facilitates the connection of two pipe flanges. This avoids the need to hold the device in place when connecting the flanges, making the pipe connection easier. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: an adaptive sealing structure, including a plug 1, a fixing plate 2 fixedly sleeved on the outside of the plug 1, and "L"-shaped sealing gaskets 3 connected to both sides of the fixing plate 2. The sealing gaskets 3 are sleeved on the outside of the plug 1. Several springs 4 are provided on both sides of the outer wall of the fixing plate 2. The other end of the springs 4 is fixedly connected to one side of the sealing gasket 3 parallel to the fixing plate 2. A rigid metal plate is fixedly embedded inside the side of the sealing gasket 3 parallel to the fixing plate 2. The side of the sealing gasket 3 perpendicular to the fixing plate 2 is a flexible rubber gasket. Multiple fixing components are provided on the circumference of the outer wall of the plug 1. Due to the two "L"-shaped sealing components... The L-shaped sealing gaskets 3 are all fixedly connected to the fixing plate 2. Therefore, under the combined action of the two sealing gaskets 3 and the fixing plate 2, the connection between the two pipes can be sealed. Under the elastic force of the spring 4, when the size of the gap between the two pipes changes, the distance between the side of the sealing gasket 3 parallel to the fixing plate 2 and the fixing plate 2 can be adjusted, so that the two pipes can still be sealed. This solves the problem that the sealing structure of the existing technology does not have self-adaptive ability, and the sealing performance is affected by thermal expansion and contraction during actual use, resulting in pipe leakage. This also limits its application.

[0021] In this embodiment, the fixing assembly includes a fixing cylinder 5, a lead screw 6, a knob 7, a telescopic assembly, and a top plate 8. The fixing cylinder 5 is fixedly inserted into the insert cylinder 1, the lead screw 6 is screwed into the inner cavity of the fixing cylinder 5, the knob 7 is located at the bottom end of the lead screw 6, and the top plate 8 is rotatably connected to the top end of the lead screw 6 via a bearing. The telescopic assembly is fixedly inserted into the insert cylinder 1 and fixedly connected to the top plate 8. By rotating the knob 7, the lead screw 6 is driven to rotate. Since the lead screw 6 is screwed into the inner cavity of the fixing cylinder 5, when the lead screw 6 rotates, it can slide within the inner cavity of the fixing cylinder 5, thereby adjusting the position of the top plate 8. This allows multiple top plates 8 to abut against the inner wall of the pipe, thus achieving the fixing of the device. The device can be fixed on one side of the pipe, facilitating the connection of two pipe flanges and avoiding the need to hold the device in place when connecting the flanges, thus simplifying the pipe connection.

[0022] In this embodiment, the outer circumference of the knob 7 is provided with anti-slip ridges, which can improve the roughness of the outer circumference of the knob 7, thereby preventing the knob 7 from slipping out of the hand when rotating, and improving the stability of the device during use.

[0023] In this embodiment, the outer wall of the top plate 8 is adapted to fit the inner wall of the pipe, which can improve the stability of the device when it is fixed in the inner cavity of the pipe.

[0024] In this embodiment, the telescopic assembly includes a telescopic cylinder 9, a telescopic rod 10, and a connecting assembly. The telescopic cylinder 9 is fixedly inserted into the insert cylinder 1. The telescopic rod 10 is slidably inserted into the inner cavity of the telescopic cylinder 9 and fixedly connected to the top plate 8. The connecting assembly is disposed in the inner cavity of the telescopic cylinder 9 and fixedly connected to the outer wall of the telescopic rod 10. Under the combined action of the telescopic rod 10 and the telescopic cylinder 9, the top plate 8 can be prevented from rotating with the lead screw 6 when the lead screw 6 rotates, thereby improving the stability of the fixing assembly during use.

[0025] In this embodiment, the connecting assembly includes a connecting groove 11 and a connecting block 12. The connecting groove 11 is formed on one side of the inner wall of the telescopic cylinder 9. The connecting block 12 is slidably embedded in the inner cavity of the connecting groove 11 and fixedly connected to the outer wall of the telescopic rod 10. Under the combined action of the connecting groove 11 and the connecting block 12, one end of the telescopic rod 10 can always be inserted into the inner cavity of the telescopic cylinder 9, which improves the stability of the telescopic assembly during use.

[0026] In this embodiment, the inner cavity of the connecting groove 11 and the outer wall of the connecting block 12 are adapted to each other and are both dovetail-shaped, which can keep one end of the connecting block 12 embedded in the inner cavity of the connecting groove 11, thus improving the stability of the connecting assembly during use.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
