Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline connector technology, and more specifically, to a detachable rubber hose assembly that is easy to maintain. Background Technology
[0002] In oil extraction, refining, and chemical production processes, rubber hose assemblies are used to transport various fluid media such as crude oil, refined oil, and chemical raw materials. For example, rubber hose assemblies on oil drilling platforms need to possess properties such as high pressure resistance, corrosion resistance, and oil resistance to adapt to harsh working environments. A rubber hose assembly is a pipeline connection device assembled from rubber hoses, connectors, and related accessories.
[0003] Commonly used pipe connections employ flanges or threads, with gaskets used to seal the joints during assembly. With flange and threaded connections, the fit between the pipe end and the gasket is affected by the size of the gasket's contact surface, and the fit strength is influenced by the insertion pressure, resulting in a poor fit. Furthermore, the gasket is susceptible to corrosion over long-term use, affecting its sealing performance. Therefore, we propose a maintenance-friendly, detachable rubber hose assembly. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a detachable rubber hose assembly that is easy to maintain, so as to solve the technical problems of poor sealing fit of current pipeline connectors and low sealing effect after corrosion.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a detachable rubber hose assembly that is easy to maintain, including a sleeve, a shell, and an adjustment component. There are two sleeves, which are connected to each other by an inner rubber sleeve. A flange is fixedly fitted to the outer end of the sleeve. The shell is fixedly connected to the two sleeves, and the inner rubber sleeve is located inside the shell. The adjustment component is installed between the shell and the inner rubber sleeve. The adjustment component consists of a spring plate and a pressure ring, and the two pressure rings are connected by the spring plate.
[0006] During installation, the external pipeline is inserted through the sleeve opening and initially fixed using a threaded connection, followed by secondary reinforcement with a flange. After installation, the external pipeline adheres to the inner wall of the inclined pressure surface of the inner rubber sleeve. At this point, the contact area is relatively small. By adjusting the component, the pressure ring is displaced relative to the internal sleeve, causing it to unfold and compress the inclined pressure surface. This deformation of the inclined pressure surface of the inner rubber sleeve increases the contact area between it and the external pipeline. Through the above structural design, the device increases the sealing contact area by allowing the inner rubber sleeve to deform, ensuring sealing performance and delaying the impact of liquid corrosion on the sealing effect, thus improving service life. Rotating the rotating ring, which rotates 90 degrees and is positioned by a snap-fit, simultaneously rotates the upper pressure ring. During the rotation, the spring plate unfolds, pushing the pressure rings at both ends to displace relative to each other, thus completing the compression of the inclined pressure surface. Through the above structural design, the pressure ring is displaced bidirectionally by external rotation. The high-intensity compression improves the fit between the inner rubber sleeve and the external pipeline connection surface, enhancing the sealing effect.
[0007] Preferably, the inner rubber sleeve has inclined pressure surfaces on both outer sides, and the narrow opening of the inclined pressure surfaces is adapted to the diameter of the matching pipe. The inner rubber sleeve has a concave arc-shaped opening in the middle.
[0008] Preferably, the cylindrical shell is composed of a rotating ring and a fixed sleeve, and the rotating ring is rotatably mounted on the fixed sleeve. Limiting rods are distributed in a circular array inside both the rotating ring and the fixed sleeve, and a positioning block is fixed to the inner end of the limiting rod.
[0009] Preferably, the rotating ring has buckles arranged in a ring array, and the fixing sleeve has a slot, with the buckles elastically engaging in the corresponding slot.
[0010] Preferably, a limiting opening is provided on the outer side of the pressure ring, and the limiting opening slides into a limiting rod, with the positioning block of the limiting rod fitting against the pressure ring.
[0011] Preferably, the spring sheet is in an inclined state and is connected and fixed to the corresponding pressure ring, the pressure ring being the inclined pressure surface of the inner rubber sleeve.
[0012] Preferably, the sleeve has a threaded opening at the port connection, and the threaded opening corresponds to the inner side of the inclined pressure surface.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the design of an inner rubber sleeve, allows the external pipeline to be inserted through the sleeve opening during installation. It is then initially fixed via a threaded connection and further reinforced by a flange. After installation, the external pipeline adheres to the inner wall of the inclined pressure surface of the inner rubber sleeve. At this point, the contact area is relatively small. By adjusting the component, the pressure ring is displaced, causing it to expand and compress the inclined pressure surface. This deformation of the inclined pressure surface of the inner rubber sleeve increases the contact area between it and the external pipeline. Through this structural design, the device increases the sealing contact area by allowing the inner rubber sleeve to deform, ensuring sealing performance, delaying the impact of liquid corrosion on the sealing effect, and improving service life.
[0015] 2. This utility model also designs a cylindrical shell with a rotating ring. The rotating ring rotates 90 degrees and is positioned by a buckle. During the rotation, it synchronously drives the upper pressure ring to rotate. During the rotation of the pressure ring, the spring plate unfolds. The unfolding of the spring plate pushes the pressure rings at both ends to move relative to each other, and the pressure ring completes the effect of squeezing the inclined surface. Through the above structural design, the pressure ring can be displaced in both directions by external rotation. The high-intensity squeezing can improve the fit between the inner rubber sleeve and the external pipeline connection surface and enhance the sealing effect. Attached Figure Description

[0025] like Figures 1 to 4 As shown, this utility model relates to a detachable rubber hose assembly that is easy to maintain, including a sleeve 2, a shell 3, and an adjusting component 5. Two sleeves 2 are provided, connected by an inner rubber sleeve 4. A flange 1 is fixedly fitted to the outer end of each sleeve 2. The shell 3 is fixedly connected to the two sleeves 2, and the inner rubber sleeve 4 is located inside the shell 3. Both ends of the inner rubber sleeve 4 have inclined pressure surfaces 401, and the narrow opening of the inclined pressure surfaces 401 is adapted to the diameter of the sleeve 2. The inner rubber sleeve 4 has a concave arc-shaped opening 402 in the middle. The shell 3 consists of a rotating ring 301 and a fixed sleeve 303, with the rotating ring 301 rotatably mounted on the fixed sleeve 303. Limiting rods 304 are arranged in a circular array inside both the rotating ring 301 and the fixed sleeve 303, and a positioning block 305 is fixed to the inner end of each limiting rod 304. The upper ring array has buckles 302 distributed on it, and the fixing sleeve 303 has a slot. The buckles 302 are elastically engaged in the corresponding slots. During installation, the external pipeline is inserted from the opening of the sleeve 2 and then initially fixed by threaded connection. Then it is reinforced by flange 1. After installation, the external pipeline is in contact with the inner wall of the inclined pressure surface 401 of the inner rubber sleeve 4. At this time, the contact surface is small. By adjusting component 5, the pressure ring 502 is moved relative to the inner wall. The pressure ring 502 unfolds and squeezes the inclined pressure surface 401. At this time, the inclined pressure surface 401 of the inner rubber sleeve 4 deforms, increasing the contact surface with the connection surface of the external pipeline. Through the above structural design, the device increases the sealing contact surface by the deformable design of the inner rubber sleeve 4, ensuring sealing performance, delaying the impact of liquid corrosion on the sealing effect, and improving service life.
[0026] like Figures 3 to 8As shown, this utility model relates to a detachable rubber hose assembly that is easy to maintain, including a sleeve 2, a cylindrical shell 3, and an adjusting component 5. The adjusting component 5 is installed between the cylindrical shell 3 and the inner rubber sleeve 4. The adjusting component 5 consists of a spring plate 501 and a pressure ring 502, and the two pressure rings 502 are connected by the spring plate 501. A limiting port 503 is provided on the outer side of the pressure ring 502, and the limiting port 503 slides and engages with a limiting rod 304. The positioning block 305 of the limiting rod 304 fits against the pressure ring 502. The spring plate 501 is in an inclined state and is connected and fixed to the corresponding pressure ring 502. The pressure ring 502 corresponds to the inclined pressing surface 4 of the inner rubber sleeve 4. 01. The port connection of the sleeve 2 is provided with a threaded opening, and the threaded opening corresponds to the inner side of the inclined pressure surface 401. Rotate the rotating ring 301, and the rotating ring 301 rotates 90 degrees and is positioned by the buckle 302. During the rotation, the upper pressure ring 502 is rotated synchronously. During the rotation of the pressure ring 502, the spring plate 501 is unfolded. The unfolding of the spring plate 501 pushes the pressure rings 502 at both ends to move relative to each other. The pressure ring 502 completes the effect of squeezing the inclined pressure surface 401. Through the above structural design, the pressure ring 502 is displaced in both directions by external rotation. The high-strength squeezing can improve the fit between the inner rubber sleeve 4 and the external pipeline connection surface and enhance the sealing effect.
[0027] Working principle: This embodiment provides a detachable rubber hose assembly that is easy to maintain. During installation, the external pipeline is inserted into the opening of the sleeve 2 and then initially fixed by threaded connection. It is then reinforced by flange 1. After installation, the external pipeline fits against the inner wall of the inclined pressure surface 401 of the inner rubber sleeve 4. At this time, the contact area is small. By adjusting component 5, the pressure ring 502 is moved relative to the inner wall. The pressure ring 502 unfolds and squeezes the inclined pressure surface 401. At this time, the inclined pressure surface 401 of the inner rubber sleeve 4 deforms, increasing the contact area between it and the external pipeline. Rotating the rotating ring 301, the rotating ring 301 rotates 90 degrees and is positioned by buckle 302. During the rotation, the upper pressure ring 502 is rotated synchronously. During the rotation of the pressure ring 502, the spring plate 501 unfolds. The unfolding of the spring plate 501 pushes the pressure rings 502 at both ends to move relative to each other. The pressure ring 502 completes the effect of squeezing the inclined pressure surface 401.
