Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to pipeline rubber coating technology, and specifically relates to a nasal pillow tube structure connected by a rotating compression ring with a threaded tube and a rubber coating part. BACKGROUND
[0002] The existing rubber coating technology of the nasal pillow tube usually adopts injection molding rubber coating directly on the outer surface of the threaded tube. Since the outer surface of the threaded tube is threaded, the irregular outer surface of the threaded tube leads to the phenomenon of glue overflow and glue runout in the injection molding process. Glue overflow and glue runout will further cause the formation of "batch edge". Excessive batch edge will cause pipeline damage, resulting in the shortening of the service life of the nasal pillow tube. SUMMARY
[0003] The utility model aims at providing a nasal pillow tube structure connected by a rotating compression ring with a threaded tube and a rubber coating part to solve the problems of glue overflow, glue runout and excessive batch edge in the existing rubber coating technology.
[0004] The technical scheme of the utility model is as follows:
[0005] A nasal pillow tube structure connected by a rotating compression ring with a threaded tube and a rubber coating part, comprising:
[0006] The threaded tube has a preset rubber coating area.
[0007] The rotating compression ring is assembled to the preset rubber coating area on the threaded tube through threaded connection.
[0008] The rubber coating part is formed by injection molding process and covers the outer surface of the rotating compression ring.
[0009] Preferably, the outer surface of the rotating compression ring is provided with a pattern for reinforcing the rubber coating part.
[0010] Preferably, the threaded tube is made of PP and TPE materials.
[0011] Preferably, the thickness of the rubber coating part is between 0.7mm and 2.2mm.
[0012] The utility model has the following beneficial effects:
[0013] By increasing a rotating compression ring, the threaded pipe is connected more closely with the encapsulating part, reduces manufacturing defects such as glue leakage, glue running, burr and other part defects, and injection molding is more stable, so that the performance of the nasal pillow pipe structure product is more stable. Specifically, the rotating compression ring is assembled and fixed at the end of the threaded pipe in a threaded manner, and then the encapsulating part is formed on the outer surface of the rotating compression ring by the injection molding process, which can ensure that the encapsulating material is accurately and uniformly distributed in the preset encapsulating area of the threaded pipe, thereby avoiding material unevenness and excess overflow during the encapsulating process, effectively avoiding burr generation, and improving the performance stability and service life of the nasal pillow pipe. At the same time, since the rotating compression ring is integrated with the threaded pipe and the encapsulating part after encapsulation, the nasal pillow pipe after encapsulation can maintain good appearance and mechanical properties, and the product yield is improved. BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1 It is a structure schematic view of the nasal pillow pipe structure of the utility model embodiment connecting the threaded pipe and the encapsulating part through the rotating compression ring.
[0015] Figure 2 It is a structure schematic view of the rotating compression ring of the utility model embodiment. DETAILED DESCRIPTION
[0016] The specific implementation of the utility model is described in detail below in combination with the drawings.
[0017] As shown in Figure 1 and Figure 2 The nasal pillow pipe structure of the utility model connecting the threaded pipe and the encapsulating part through the rotating compression ring comprises a threaded pipe 1, and a rotating compression ring 3 is assembled on the threaded pipe 1.
[0018] Among them, the threaded pipe 1 is made of PP and TPE materials.
[0019] The rotating compression ring 3 and the threaded pipe 1 are connected in a threaded manner, and the rotating compression ring 3 can exert sufficient pressure to tightly adhere the surface of the rotating compression ring 3 and the threaded pipe 1, thereby preventing gas or liquid leakage.
[0020] The encapsulating part 2 is formed on the outer surface of the rotating compression ring 3 by the injection molding process, which can ensure that the encapsulating material is accurately and uniformly distributed in the preset encapsulating area of the threaded pipe 1, thereby avoiding material unevenness and excess overflow during the encapsulating process, effectively avoiding burr generation, and improving the performance stability and service life of the nasal pillow pipe.
[0021] Overall, before injection encapsulation, the rotating compression ring 3 is rotated to the end of the threaded pipe 1, and the encapsulating part 2 is directly injection encapsulated on the outer surface of the rotating compression ring 3. After encapsulation, the rotating compression ring 3, the threaded pipe 1 and the encapsulating part 2 are integrated and cannot be disassembled.
[0022] After the injection molding, the thickness of the formed encapsulation 2 is between 0.7mm and 2.2mm.
[0023] With reference to Figure 2 In the embodiments of the present application, the outer surface of the rotating pressure ring 3 is provided with a texture 31 for stabilizing the encapsulation 2. The texture 31 can prevent the encapsulation 2 formed after encapsulation from being structurally damaged due to external forces such as pulling and rotating, thereby improving the structural stability.
[0024] Although only a limited number of embodiments are explained in detail, the present application is not limited to the application listed in the specification and the embodiments, and can be fully applied to various fields suitable for the present application. For engineering technicians familiar with the art, other modifications, supplements and substitutions can be easily realized, and therefore the present application should not be considered as limited by the foregoing description without departing from the general concept defined by the claims and the equivalent scope.
