Description

Technical Field

[0001] This utility model relates to the field of heating and ventilation technology, and in particular to an easy-to-install and easy-to-disassemble pipe for heating and ventilation. Background Technology

[0002] In modern building heating and ventilation systems, pipes are the key carriers for heat and air transfer. The ease of installation and dismantling of pipes has a crucial impact on construction efficiency, subsequent maintenance costs, and overall system performance. With the acceleration of urbanization and the booming development of the construction industry, the application scenarios of heating and ventilation systems are becoming increasingly widespread. Whether it is a residential building, a commercial complex, or an industrial plant, there are high requirements for the installation and dismantling of pipe systems.

[0003] Traditional heating and ventilation ducts are typically installed using welding. While welding ensures a strong connection, it requires highly skilled workers and poses safety hazards due to the high temperatures and sparks generated during the process. Furthermore, once welded, subsequent repairs and replacements are extremely difficult, often requiring structural damage and wasting materials. Existing flange connections offer greater convenience, particularly during disassembly. This method allows for easy assembly and disassembly without damaging the duct structure, ensuring the integrity and stability of the system. The reliability and stability of flange connections eliminate concerns about potential safety hazards. However, flange installation is more complex, requiring numerous bolts and nuts, increasing installation time and labor costs. Over time, thermal expansion and contraction can cause bolts to loosen, leading to air and water leaks, disrupting the heating and ventilation system and failing to meet user needs.

[0032] Specifically, the system includes a flow pipe 1, the outer wall of which is covered with a layer of polyurethane foam 3. This polyurethane foam 3 not only has good thermal insulation properties but also effectively reduces heat loss. A layer of aluminum foil 4 is further covered on the outer wall of the polyurethane foam 3. The main function of the aluminum foil 4 is to reflect heat, further enhancing the thermal insulation effect. The outer wall of the aluminum foil 4 is wrapped with a sturdy aluminum sheet 5. The aluminum sheet 5 not only enhances the mechanical strength of the entire pipe but also has good corrosion resistance. On both sides of the outer wall of the aluminum sheet 5, there are slidably connected fixed frames 6. This sliding connection method allows the fixed frames 6 to be flexibly adjusted in position, facilitating installation and maintenance. A limit block 7 is firmly fixed to the bottom of the fixed frame 6. The function of the limit block 7 is to ensure that the fixed frame 6 does not exceed a predetermined range during sliding. A circular hole 8 is opened in the center of the limit block 7. The inner wall of the circular hole 8... The sliding connection is provided by screw 9, which can be adjusted by rotation to achieve precise fixation of the fixed frame 6. The rear side of screw 9 is connected by a bolt 10 via a thread. Tightening and loosening the bolt 10 can further reinforce or disassemble the entire structure. On the inner wall of the flow pipe 1, a cross frame 11 is fixedly connected, which increases the internal support strength of the pipe. A motor 12 is fixedly connected to the left side of the cross frame 11. The motor 12 is the power source of the entire system. A fan 13 is fixedly connected to its output end. The function of the fan 13 is to drive airflow and ensure smooth gas flow in the pipe. In addition, a disassembly mechanism 2 is provided on the outer wall of the aluminum sheet 5. This disassembly mechanism 2 can easily and quickly disassemble and install the pipe, greatly facilitating daily maintenance and repair work. The entire flow pipe 1 not only has good heat preservation and ventilation performance, but also has high flexibility and convenience.

[0033] Please see the appendix Figure 1 - Appendix Figure 3 The disassembly mechanism 2 includes a semi-iron ring 201, the inner wall of which is set on the outer wall of the flow pipe 1. A rotating shaft 202 is rotatably connected to the rear side of the semi-iron ring 201. A support column 203 is fixedly connected to the bottom of the rotating shaft 202.

A knob 208 is threadedly connected to the middle of the outer wall of the swing column 206.

[0034] Specifically, the disassembly mechanism 2 includes a component called a semi-iron ring 201. The inner wall of the semi-iron ring 201 is tightly fitted and disposed on the outer wall of the flow pipe 1 to ensure a stable connection between the two. On the rear side of the semi-iron ring 201, a rotating shaft 202 is installed by a rotatable connection. The bottom of the rotating shaft 202 is firmly fixedly connected to a support column 203. The main function of the support column 203 is to provide stable support force. The bottom of the support column 203 is further fixedly connected to a component called a semi-iron ring 204, forming a complete support structure. On the front side of the semi-iron ring 201, a rotating shaft 205 is fixedly connected. The outer wall of the rotating shaft 205 is connected to a swing column 206 by a rotatable connection. The swing column 206 allows it to swing flexibly to adapt to different operating needs. A handle 207 is firmly fixedly connected to the bottom of the swing column 206. The handle 207 is convenient for the operator to hold and operate. In addition, a knob 208 is installed in the middle of the outer wall of the swing column 206 by a threaded connection. The function of the knob 208 is to adjust and fix the position of the disassembly mechanism 2 to ensure stability and accuracy during operation.

[0035] Please see the appendix Figure 3 - Appendix Figure 5 A protruding ring 14 is fixedly connected to the right side of the flow pipe 1. An anti-slip sleeve 25 is fixedly connected to the outer wall of the knob 208. An annular frame 16 is fixedly connected to the left side of the outer wall of the flow pipe 1 near the edge.

Multiple nuts 19 are fixedly connected to the left side of the annular frame 27.

[0036] Specifically, the flow channel 1 has a raised annular structure, namely a raised ring 14, securely fixed to its right side. This raised ring 14 provides additional support and positioning. Meanwhile, the knob 208 has an anti-slip sleeve 25 securely attached to its outer wall. The main function of the anti-slip sleeve 25 is to increase the friction of the knob 208, thereby preventing slippage during use and improving operational safety and convenience. Furthermore, on the left side of the flow channel 1 near the edge, a ring-shaped frame structure, namely an annular frame 16, is stably fixed to it. The presence of the annular frame 16 primarily enhances the structural strength and stability of the flow channel 1. Similarly, the flow channel 1 has a raised annular frame 16 on its right side of the outer wall... Near the edge, another annular frame structure, namely annular frame 17, is also securely connected. Annular frame 17 functions similarly to annular frame 16, providing support and reinforcement. In addition, annular frame 16 has multiple screws 18 slidably connected to its right side. These screws 18 can slide along the right side surface of annular frame 16 for fixing and adjustment in different positions. Correspondingly, annular frame 17 has multiple nuts 19 fixedly connected to its left side. These nuts 19 work in conjunction with screws 18 to achieve a tight connection and secure fixation of the flow pipe 1 and its related components, ensuring the reliability and durability of the entire structure.

[0037] Please see the appendix Figure 1 - Appendix Figure 3 Multiple circular holes 20 are provided in the middle of the ring frame 2 17. A rubber pad 15 is fixedly connected to the right side of the flow pipe 1 near the middle. A support column 21 is fixedly connected to the bottom of the half iron ring 204. A base 22 is fixedly connected to the bottom of the support column 21. Multiple circular holes 3 23 are provided on the top of the base 22. A reflector 24 is fixedly connected to the middle of the top of the base 22.

[0038] Specifically, the annular frame 217 has multiple circular holes 20 evenly spaced in the middle of its structure. These circular holes 20 enhance the overall ventilation and circulation effect. A rubber pad 15 is securely connected to the circulation pipe 1 on its right side near the center. The main function of the rubber pad 15 is to provide cushioning and sealing, ensuring the stability and safety of the circulation pipe 1 during operation. A support column 21 is securely connected to the bottom of the semi-iron ring 204. This support column 21 provides stable support for the entire structure. A base 22 is further securely connected to the bottom of the support column 21. This base 22 serves as the foundation of the entire device, providing a solid support platform. Multiple circular holes 33 are evenly spaced at the top of the base 22. Furthermore, a reflector 24 is securely connected to the top center of the base 22. The main function of the reflector 24 is to reflect light, enhancing the visibility and safety of the device.

[0039] Working principle: To achieve convenient heating, the outer wall of the circulation pipe 1 is wrapped with polyurethane foam 3, which has good thermal insulation properties. The outer wall of the polyurethane foam 3 is wrapped with an aluminum foil layer 4 to prevent moisture. Then, an aluminum sheet 5 is wrapped on the outside to form a protective layer, so as to prevent external mechanical damage and environmental factors. The left and right sides are fixed by a fixed frame 6. The screws 9 pass through the circular holes 8 and are threadedly connected to the bolts 10 to achieve the thermal insulation effect. The inner wall of the circulation pipe 1 has a motor 12. When it is turned on, the fan 13 at the output end works, which accelerates the exchange speed of air between the inside and outside, promotes air circulation, and makes the ventilation effect more significant, thus meeting the needs of users.

[0040] When the pipe needs to be disassembled, loosen the knob 208, hold the handle 207 and pull it outward. The swing column 206 rotates around the second pivot 205, so that the half iron ring 201 can be detached from the outer wall of the aluminum sheet 5. The rear side of the half iron ring 201 rotates around the first pivot 202 without falling off, ensuring safety. At this time, the flow pipe 1 can be removed. This structure eliminates the need for frequent screw tightening, and the disassembly speed is fast, meeting the needs of users.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
