Description

Technical Field

[0001] This utility model relates to the field of connecting devices, and in particular to a heat insulation pipe connecting structure. Background Technology

[0002] Insulated pipes are pipeline engineering accessories installed on pipelines and equipment for functions such as heat preservation, corrosion prevention, and heat insulation. Insulated pipes generally consist of components such as the pipe itself, insulation layer, waterproof layer, steel sleeve, and supports. The main purpose of insulated pipes is to reduce energy loss during transportation, lower operating temperature, save energy, and prevent damage to pipelines and equipment under high-temperature radiation conditions. During installation, a connecting structure is required for assistance. Currently, the connection methods for insulated pipes are mostly heat fusion, threaded spiral, and adhesive connections. These methods are mostly fixed connections with non-adjustable angles. During construction, if obstacles are encountered, laying the pipe and connecting the pipes becomes very difficult, causing delays in construction progress and economic losses. Forcibly bending the angle may cause leaks at the connection, wasting manpower and materials. Furthermore, current connection methods do not provide effective insulation and reinforcement at the connection points, resulting in insignificant insulation effects and affecting the overall insulation performance of the pipeline. Therefore, we propose an insulated pipe connection structure. Utility Model Content

[0003] The main purpose of this utility model is to provide a heat insulation pipe connection structure that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An insulated pipe connection structure includes an inner straight pipe, an inner flared pipe fixedly installed on the rear surface of the inner straight pipe, a front connecting plate fixedly installed on the front surface of the inner straight pipe, front fixing blocks fixedly installed on one side and the other side of the front connecting plate, a front clamp fixedly installed in front of the front connecting plate, a front clamp bolt fixedly installed on the upper surface of the front clamp, a rear connecting plate fixedly installed on the rear surface of the inner flared pipe, a rear fixing block fixedly installed on one side and the other side of the rear connecting plate, a front pipe movably clamped on the front surface of the inner straight pipe, and a rear pipe movably clamped inside the rear connecting plate.

[0006] Preferably, a rear pipe interface is fixedly installed on the rear surface of the rear connecting plate, a rear sealing ring is embedded in the rear of the rear pipe interface near the rear position, a rear clamp is fixedly installed behind the rear pipe interface, and a rear clamp bolt is fixedly installed on the upper surface of the rear clamp.

[0007] Preferably, a front sealing ring is fixedly installed on the front surface of the front connecting plate, and a front connecting plate base is fixedly installed on the lower surface of the front connecting plate.

[0008] Preferably, a front movable component is fixedly installed on the front surface of the front fixed block, a front pull rod is embedded inside the front movable component, a front fixed component is fixedly installed on one side surface of the front clamp, and the front fixed component is connected to the front movable component via the front pull rod.

[0009] Preferably, a rear movable component is fixedly installed on the rear surface of the rear fixed block, a rear pull rod is embedded inside the rear movable component, a rear fixed component is fixedly installed on one side surface of the rear clamp, and the rear fixed component is connected to the rear movable component via the rear pull rod.

[0010] Preferably, an outer protective cover is fixedly installed on the rear surface of the front connecting plate, and an injection port is provided on the upper surface of the outer protective cover.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, the worker can first insert the pipe to be connected through the front clamp, then into the front connecting plate, with the pipe connected to the inner straight pipe. Then, tighten the front clamp bolts with a wrench. The front fixing block creates tension between the pipe and the connecting structure, making the connection tighter. Next, insert the pipe to be connected through the rear clamp, then into the rear pipe connection port, with the pipe connected to the rear connection port. The connecting structure has sealing rings at both the front and rear, and because it is internally connected to the connecting device, the sealing is guaranteed. Then, tighten the rear clamp bolts with a wrench. The rear fixing block creates tension between the pipe and the connecting structure, making the connection even tighter. When fine-tuning the angle is needed, simply move and adjust. Because the internal flared tube is made of rubber and has a narrow front and wide rear design, the pipe angle can be finely adjusted without affecting the sealing of the connection. At this point, the pipe is connected. The entire installation process is convenient, requiring only a wrench, thus improving installation efficiency. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, an insulation pipe connection structure includes an inner straight pipe 1, which is made of rigid plastic. An inner flared pipe 2, made of soft rubber, is fixedly installed on the rear surface of the inner straight pipe 1. A front connecting plate 3 is fixedly installed on the front surface of the inner straight pipe 1. A front fixing block 4 is fixedly installed on one side and the other side of the front connecting plate 3. A front clamp 5 is fixedly installed in front of the front connecting plate 3. A front clamp bolt 501 is fixedly installed on the upper surface of the front clamp 5. A rear connecting plate 7 is fixedly installed on the rear surface of the inner flared pipe 2. A rear fixing block 8 is fixedly installed on one side and the other side of the rear connecting plate 7. A front pipe 10 is movably clamped on the front surface of the inner straight pipe 1. A rear pipe 11 is movably clamped inside the rear connecting plate 7.

[0020] A rear pipe interface 701 is fixedly installed on the rear surface of the rear connecting plate 7. A rear sealing ring 702 is embedded in the rear pipe interface 701 near the rear. A rear clamp 9 is fixedly installed behind the rear pipe interface 701, and a rear clamp bolt 901 is fixedly installed on the upper surface of the rear clamp 9. A front sealing ring 301 is fixedly installed on the front surface of the front connecting plate 3. A front connecting plate base 302 is fixedly installed on the lower surface of the front connecting plate 3. The height of the front connecting plate base 302 is the same as that of the rear connecting plate 7 to maintain the balance and stability of the connection structure. A front movable part 401 is fixedly installed on the front surface of the front fixing block 4. The front movable part 401 is fastened with screws. A front pull rod 402 is embedded in the front movable part 401 and fastened with screws. The front pull rod 402 is a replaceable design. After the angle of the front pipe 10 is finely adjusted, a front pull rod 402 of appropriate length can be replaced for reinforcement. A front fixing part 403 is fixedly installed on one side surface of the front clamp 5. Part 403 is connected to the front movable part 401 via the front pull rod 402. The front pull rod 402 allows the front pipe 10 and the connecting device to generate tension, thereby improving the connection. The rear movable part 801 is fixedly installed on the rear surface of the rear fixed block 8 and is fastened with screws. The rear pull rod 802 is embedded inside the rear movable part 801 and is also fastened with screws. The rear pull rod 802 is a replaceable design, allowing for the replacement of a rear pull rod 802 of appropriate length. For reinforcement, a rear fixing component 803 is fixedly installed on one side of the rear clamp 9. The rear fixing component 803 is connected to the rear movable component 801 via a rear pull rod 802. The rear pull rod 802 can generate tension between the rear pipe 11 and the connecting device, thereby achieving a better connection. An outer protective cover 6 is fixedly installed on the rear surface of the front connecting plate 3. The outer protective cover 6 is made of soft rubber. A filling port 601 is opened on the upper surface of the outer protective cover 6. A rotating bottle cap is provided on the upper surface of the filling port 601 for sealing.

[0021] It should be noted that this utility model is a connection structure for an insulated pipe. During use, the operator first needs to pass the front pipe 10 through the front clamp 5, and then insert it into the front connecting plate 3. A front sealing ring 301 is provided on the front surface of the front connecting plate 3. The front pipe 10 passes through the front sealing ring 301 and is connected to the inner straight pipe 1. At this time, a wrench is needed to tighten the front clamp bolt 501. Through the provided front fixing block 4, tension is generated between the front pipe 10 and the connection structure, thereby making the connection between the front pipe 10 and the connection structure more secure. The design of the sealing ring 301 and its inner connection to the inner straight pipe 1 ensures a tight seal. The rear pipe 11 then needs to be passed through the rear clamp 9 and inserted into the rear pipe interface 701. A rear sealing ring 702 is provided on the rear surface of the rear pipe interface 701. The rear pipe 11 is then connected to the rear pipe interface 701 via the rear sealing ring 702. The rear clamp bolt 901 needs to be tightened with a wrench. The rear fixing block 8 creates tension between the rear pipe 11 and the connecting structure, thus connecting the rear pipe 11 and the connecting structure. The design of the rear sealing ring 702 and the inner connection to the rear pipe interface 701 ensures a more robust seal, thus completing the connection process. If a fine-tuning of the angle is required, simply move the front pipe 10 to the appropriate angle. Both the inner flared tube 2 and the outer protective cover 6 are made of soft rubber, possessing excellent sealing and ductility, allowing for direct angle adjustments without affecting the structural seal. Because the inner flared tube 2, as a conveying component, does not directly contact the rear pipe 11 but is fixedly connected to the rear connecting plate 7, fine-tuning the angle of the inner flared tube 2 will not affect the structural seal. After adjusting the angle, the connection can be reinforced according to the actual situation by injecting insulating and reinforcing materials such as expanding foam into the filling port 601, and finally covering it with the rotating cap, allowing the expanding foam to solidify. This provides both insulation and reinforcement to the connection, making it more robust and stable. Furthermore, the device is easy to install, requiring only a wrench, thus improving installation efficiency.
