Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline protection technology, and in particular to pipeline protection devices. Background Technology
[0002] During transportation, storage, and application, contaminants such as air, water, and dust frequently enter the interior of pipes, causing them to accumulate. For example, in the home furnishing industry, the stainless steel tubing in bed frames easily accumulates dust or insects. Currently, the most common solution is to seal the ends of the pipes with caps. However, during handling or assembly of bed frames, the pipe ends are easily struck by hard external objects, causing the caps to break and deform, thus reducing the sealing effect. Utility Model Content
[0003] The purpose of this utility model is to provide a pipeline protection device that uses protective components to protect the sealing components and ensure the sealing effect of the sealing components.
[0004] To achieve this objective, the present invention adopts the following technical solution:

[0007] A protective element is disposed on the second surface of the seal, the protective element having a third surface close to the seal and a fourth surface away from the seal, the hardness of the protective element being less than the hardness of the seal.
[0008] As an optional technical solution, the second surface of the seal is recessed inward to form a mounting groove, and the protective member is at least partially and tightly disposed within the mounting groove.
[0009] As an optional technical solution, one of the second surface and the third surface is recessed inward to form an embedding groove, and the other surface is protruded outward to form an embedding part, which is tightly embedded in the embedding groove.

[0011] As an optional technical solution, the plane with the embedding groove protrudes outward to form a support platform, the embedding groove surrounds the periphery of the support platform, the plane with the embedding part is recessed inward to form a receiving groove, the embedding part surrounds the periphery of the receiving groove, and the platform surface of the support platform abuts against the bottom of the receiving groove.
[0012] As an optional technical solution, the sealing element includes a sealing layer and a connecting platform. The sealing layer has a first side close to the pipe and a second side away from the pipe. The protective element is disposed on the second side of the sealing layer. The connecting platform extends outward from the first side of the sealing layer. The periphery of the connecting platform is provided with an abutment layer. The abutment layer elastically abuts against the inner wall of the pipe. The sealing layer seals the port of the pipe.
[0013] As an optional technical solution, the periphery of the abutment layer is provided with an inclined surface, which is located on the side of the abutment layer opposite to the sealing layer.
[0014] As an optional technical solution, the thickness of the abutment layer at the portion with the inclined surface gradually decreases along the direction away from the connecting platform.

[0017] The beneficial effects of this utility model are:
[0018] The pipeline protection device of this utility model includes a sealing element and a protective element. The sealing element is used to seal the pipeline and has a first surface close to the pipeline and a second surface away from the pipeline. The protective element is disposed on the second surface of the sealing element and has a third surface close to the sealing element and a fourth surface away from the sealing element. The hardness of the protective element is less than that of the sealing element.
[0019] When an external hard object moves toward the end of the pipe, the protective component can prevent the external hard object from hitting the seal, preventing the seal from being damaged and ensuring that the sealing performance of the seal is not affected.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0028] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0029] like Figure 1 and Figure 2 As shown, the pipeline protection device provided in this embodiment includes a sealing element 1 and a protective element 2. The sealing element 1 is used to seal the pipeline and has a first surface close to the pipeline and a second surface away from the pipeline. The protective element 2 is disposed on the second surface of the sealing element 1 and has a third surface close to the sealing element 1 and a fourth surface away from the sealing element 1. The hardness of the protective element 2 is less than that of the sealing element 1.
[0030] Specifically, when an external hard object moves toward the end of the pipe, such as when folding a bed frame, the various pipes of the bed frame move relative to each other. The protective component 2 can prevent the external hard object, such as another pipe, from hitting the seal 1, preventing the seal 1 from being damaged and ensuring that the sealing performance of the seal 1 is not affected. The hardness of the protective component 2 is less than that of the seal 1. Compared with the seal 1, the protective component 2 has a stronger elastic deformation ability. When an external hard object hits the protective component 2, the protective component 2 can absorb part of the impact and produce less noise.
[0031] Optionally, the sealing element 1 is made of plastic, and the protective element 2 is made of rubber or sponge. Plastic has a higher hardness than rubber and sponge, so when an external hard object impacts the rubber or sponge, the rubber or sponge can absorb the impact, protecting the sealing element 1. Simultaneously, the noise generated by the impact is reduced. The sealing element 1 is embedded inside the pipe. Due to the relatively high hardness of the plastic, the installation stability of the sealing element 1 within the pipe is ensured, and no electro-corrosion occurs between the plastic and the stainless steel pipe, guaranteeing the product's service life.
[0032] Optionally, the second surface of the seal 1 is recessed inward to form a mounting groove 114, and the protective element 2 is at least partially and tightly disposed within the mounting groove 114. The seal 1 and the protective element 2 are installed with an interference fit, eliminating the need for additional locking components, reducing costs, and eliminating the need to consider the problem of external hard objects impacting the fasteners.
[0033] Optionally, one of the second and third surfaces is recessed inward to form an insert groove 111, and the other is protruded outward to form an insert portion 21, which is tightly fitted into the insert groove 111. This tight fit ensures the connection strength between the protective member 2 and the sealing member 1, preventing the protective member 2 from detaching from the sealing member 1.
[0034] In this embodiment, the second surface is recessed inward to form an embedding groove 111, and the third surface protrudes outward to form an embedding portion 21. In other embodiments, the third surface is recessed inward to form an embedding groove 111, and the second surface protrudes outward to form an embedding portion 21.
[0035] In this embodiment, the embedding groove 111 is formed inside the mounting groove 114. In other embodiments, the embedding groove 111 is formed outside the mounting groove 114. The two are independent of each other and are not connected to each other.
[0036] Optionally, one of the second and third surfaces is recessed inward to form a socket 112, and the other is protruded outward to form a post 22. The post 22 is tightly inserted into the socket 112, further strengthening the connection between the protective member 2 and the sealing member 1, and preventing the protective member 2 from detaching from the sealing member 1.
[0037] In this embodiment, the second surface is recessed inward to form a insertion hole 112, which is located at the bottom of the embedding groove 111, and the third surface protrudes outward to form a insertion post 22, which is located in the embedding portion 21. In some other embodiments, the third surface is recessed inward to form the insertion hole 112, and the second surface protrudes outward to form the insertion post 22.
[0038] Optionally, the plane with the embedding groove 111 protrudes outward to form a support platform 113, the embedding groove 111 surrounds the periphery of the support platform 113, and the plane with the embedding part 21 is recessed inward to form a receiving groove 23, the embedding part 21 surrounds the periphery of the receiving groove 23, and the platform surface of the support platform 113 abuts against the bottom of the receiving groove 23. The support platform 113 supports the protective member 2 and prevents a void space from appearing between the protective member 2 and the sealing member 1.
[0039] Optionally, the seal 1 includes a sealing layer 11 and a connecting platform 12. The sealing layer 11 has a first side close to the pipe and a second side away from the pipe. The protective member 2 is disposed on the second side of the sealing layer 11. The connecting platform 12 extends outward from the first side of the sealing layer 11. The periphery of the connecting platform 12 is provided with an abutment layer 13. The abutment layer 13 elastically abuts against the inner wall of the pipe. The sealing layer 11 seals the port of the pipe.
[0040] When the connecting platform 12 extends into the interior of the pipe, the abutment layer 13 undergoes elastic deformation and elastically abuts against the inner wall of the pipe. After the connecting platform 12 is fully extended into the interior of the pipe, the sealing layer 11 seals the port of the pipe to prevent external pollutants such as dust or insects from entering the interior of the pipe.
[0041] Optionally, the periphery of the abutment layer 13 is provided with an inclined surface 131, which is located on the side of the abutment layer 13 away from the sealing layer 11. When the connecting platform 12 begins to enter the interior of the pipe, the inclined surface 131 abuts against the edge of the pipe port, and the inclined surface 131 activates the guiding and alignment function to ensure that the entire abutment layer 13 and the connecting platform 12 can be accurately inserted into the interior of the pipe.
[0042] Optionally, the thickness of the portion of the abutment layer 13 with the inclined surface 131 gradually decreases along the direction away from the connecting platform 12, which makes it easier for the portion of the abutment layer 13 with the inclined surface 131 to elastically deform. When it is necessary to remove the seal 1, the portion of the abutment layer 13 with the inclined surface 131 deforms in the opposite direction. Since the portion of the abutment layer 13 with the inclined surface 131 is easy to elastically deform, the seal 1 can be pulled out relatively easily.
[0043] Optionally, the periphery of the abutment layer 13 is provided with a deformation port 132. In this embodiment, the abutment layer 13 is provided with deformation ports 132 at all four corners, and there are four unconnected portions of the abutment layer 13 with inclined surfaces 131. The deformation ports 132 serve to avoid interference, making the portions of the abutment layer 13 with inclined surfaces 131 more prone to elastic deformation, thus allowing the seal 1 to be pulled out more easily.
[0044] Optionally, the connecting platform 12 includes a first connecting layer 121 and a second connecting layer 122, which are vertically connected. An abutment layer 13 surrounds the periphery of the first connecting layer 121 and the second connecting layer 122. The first connecting layer 121 and the second connecting layer 122 support the abutment layer 13 in two mutually perpendicular directions to ensure the structural strength of the root of the abutment layer 13.
[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
