Description

Technical Field

[0001] This utility model belongs to the field of flexible air duct adjustment technology, specifically relating to a flexible air duct that is easy to disassemble. Background Technology

[0002] In ventilation, air conditioning, and industrial air supply, flexible ducts are widely used due to their flexibility and adaptability to complex installation environments. The stability of their connection with connecting pipes and external equipment, as well as the ease of disassembly, directly affects the efficiency of equipment installation and maintenance. Traditional flexible duct connection methods often use fixed connection structures, such as welding and flange fastening. Although these methods provide a stable connection, disassembly for maintenance or replacement is complex and time-consuming, and may even require specialized tools and technicians, increasing maintenance costs and downtime.

[0003] Therefore, there is an urgent need to provide a flexible air duct that is easy to disassemble in order to solve the problems mentioned in the background art. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a flexible air duct that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a flexible air duct that is easy to disassemble, comprising: a flexible air duct, a connecting pipe at one end of the flexible air duct, rubber sleeves at both ends of the connecting pipe, a fixing component on the rubber sleeve, the fixing component including an adjusting belt and a retractable sleeve, the tail end of the adjusting belt being fixed to the lower end of the retractable sleeve, the retractable sleeve having a through groove and a screw hole inside, the head end of the adjusting belt passing through the through groove, and a bolt being threaded into the screw hole.

[0006] As further explained, the thickness of the groove is adapted to the thickness of the adjustment belt.

[0007] As further explained, the lower end of the groove is connected to the upper end of the screw hole, and when the bolt is connected to the screw hole, the adjusting band is tightly pressed into the groove by the bolt.

[0008] As a further explanation, the rubber sleeve at one end of the connecting pipe is tightly fitted onto the outer periphery of one end of the flexible air duct, and the elastic deformation of the rubber sleeve is used to achieve a sealed fit.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model replaces traditional flange bolt assemblies or welding methods with a unique fixing assembly consisting of an adjusting belt, a retractable sleeve, and bolts. Disassembly is simple: loosening the bolts releases the constraint; installation is complete by tightening the adjusting belt and bolts. This process requires no special tools, is quick and easy, significantly reducing downtime for equipment maintenance, cleaning, or layout adjustments, and lowering labor costs.

[0010] 2. Utilizing the elastic deformation of the rubber sleeve, it tightly fits around the outer perimeter of the flexible air duct and connecting pipe, forming an effective sealing layer. The fixing component, by tightening the adjusting strap, can evenly press the rubber sleeve onto the connection surface, ensuring the airtightness of the connection and effectively preventing air leakage. At the same time, the flexible rubber sleeve can buffer vibration, making the connection more reliable.

[0011] 3. The entire connection structure has few components, a simple construction, and is easy to manufacture and assemble. This design does not require high manufacturing precision for the flexible duct and connecting pipe. Through the adaptive deformation of the rubber sleeve and the flexible tension of the adjusting belt, it can accommodate dimensional tolerances within a certain range, exhibiting strong versatility. Compared to complex quick-connect mechanisms, this invention effectively controls manufacturing costs while achieving convenient functionality.

[0012] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figure 1-3 A flexible air duct that is easy to disassemble includes: a flexible air duct 1, a connecting pipe 2 at one end of the flexible air duct 1, rubber sleeves 201 at both ends of the connecting pipe 2, a fixing component 3 on the rubber sleeves 201, the fixing component 3 including an adjusting belt 301 and a retractable sleeve 302, the tail end of the adjusting belt 301 being fixed to the lower end of the retractable sleeve 302, the retractable sleeve 302 having a through groove 303 and a screw hole 304, the head end of the adjusting belt 301 passing through the through groove 303, and a bolt 305 being threaded into the screw hole 304. The rubber sleeves 201 at both ends of the connecting pipe 2 are adapted to the connection ends of the flexible air duct 1 and the external equipment, respectively, and the flexibility of the rubber achieves initial contact. The tail end of the adjusting band 301 of the fixing component 3 is fixed to the retracting sleeve 302, and the head end passes through the through groove 303 and is tightened, which can drive the rubber sleeve 201 to retract, so as to achieve a tight fit between the connecting pipe 2 and another flexible air duct or external equipment. After the bolt 305 in the screw hole 304 is tightened, the adjusting band 301 in the through groove 303 is pressed, locking the tightened state of the adjusting band 301 and preventing loosening. This design replaces the traditional fixed structure such as welding and flange fastening. The disassembly and assembly of this design only requires loosening or tightening the bolt 305 and pulling the adjusting band 301, without the need for professional tools and technicians, greatly shortening the operation time and significantly reducing maintenance costs and downtime.

[0019] The thickness of the slot 303 is matched with the thickness of the adjusting belt 301. This ensures that the adjusting belt 301 can only slide along its length within the slot 303, while also preventing the adjusting belt 301 from shifting or getting stuck within the slot 303 due to excessive gaps. This makes the tightening or loosening of the adjusting belt 301 smoother and further improves assembly and disassembly efficiency.

[0020] The lower end of the slot 303 is connected to the upper end of the screw hole 304. When the bolt 305 is connected to the screw hole 304, the adjusting band 301 is tightly pressed into the slot 303 by the bolt 305. After the bolt 305 is screwed into the screw hole 304, its end will directly enter the inside of the slot 303 and press the passing adjusting band 301 against the bottom or side wall of the slot 303. This "top-pressing" locking method is very direct and efficient. The axial locking force of the bolt 305 is directly converted into a radial pressing force on the adjusting band 301. The force flow path is clear and the locking force is large.

[0021] The rubber sleeve 201 at one end of the connecting pipe 2 is tightly fitted onto the outer periphery of one end of the flexible air duct 1, and the elastic deformation of the rubber sleeve 201 achieves a sealing fit. Utilizing the elastic deformation characteristics of the rubber sleeve 201, after it is tightly fitted onto the outer periphery of the flexible air duct 1, the rubber material deforms due to compression, filling the gap between the flexible air duct 1 and the connecting pipe 2, thus achieving a seamless seal.

[0022] All components selected in this application (parts whose specific structures are not described) are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals. This knowledge can be obtained through conventional experimental methods.

The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.

[0024] In addition, in the various embodiments of this utility model, each functional unit can be integrated into one processing unit, or each unit can exist physically separately, or two or more units can be integrated into one unit.

[0025] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
