Description

Technical Field

[0001] This utility model relates to the field of ventilation ducts, specifically a low-resistance, high-efficiency ventilation duct. Background Technology

[0002] Ventilation ducts are hollow pipes used for ventilation, mostly round or square. The plates, profiles, and other main finished materials used in the fabrication and installation of ventilation ducts include: air supply and return ducts for purification systems, ventilation ducts for central air conditioning, ventilation ducts for industrial air supply and exhaust, ventilation ducts for environmental protection systems, gas extraction pipes for mines, coated cloth ventilation ducts for mines, and ventilation ducts for fire-fighting smoke ducts, etc.

[0003] However, current ventilation ducts still have some shortcomings. For example, existing ventilation ducts are mostly connected and fixed with multiple sets of bolts and nuts, which requires workers to spend a long time disassembling and assembling them during maintenance. This interferes with the efficiency of workers in replacement and maintenance, and thus has certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure to provide a low-wind-resistance and high-efficiency ventilation pipe. Utility Model Content

[0005] The purpose of this invention is to provide a low-resistance, high-efficiency ventilation duct to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-resistance, high-efficiency ventilation duct, comprising a stainless steel ventilation duct body and a second mounting bracket. The inner surface of the stainless steel ventilation duct body is provided with a corrosion-resistant coating, and a first mounting bracket is fixedly installed on the outer surface of one end of the stainless steel ventilation duct body. A positioning groove is provided on the side of the first mounting bracket. The second mounting bracket is fixedly installed on the outer surface of the other end of the stainless steel ventilation duct body, and a positioning rod is fixedly installed on the side of the second mounting bracket. A fixing plate is fixedly installed on the other side of the second mounting bracket, and a connecting shaft is rotatably connected inside the fixing plate. At the same time, a locking component is fixedly connected to the outer surface of the connecting shaft.

[0007] Furthermore, the external dimensions of the positioning rod perfectly match the internal dimensions of the positioning groove, and the positioning rod forms a locking structure with the first mounting frame through the positioning groove.

[0008] Furthermore, the locking assembly includes an L-shaped locking frame, a connecting sleeve, and a clamping and limiting mechanism. The connecting sleeve is fixedly installed on the inner surface of the L-shaped locking frame, and the clamping and limiting mechanism is movably installed on the inner surface of the other side of the L-shaped locking frame.

[0009] Furthermore, the interior of the connecting sleeve is fixedly connected to the outer surface of the connecting shaft, and the end of the connecting shaft is rotatably connected to the interior of the fixing plate. The connecting sleeve and the fixing plate form a rotating structure through the connecting shaft.

[0010] Furthermore, the clamping and limiting mechanism includes a clamping plate, a connecting seat, a fixing rod, a connecting plate, a pull ring, a strong elastic limiting mechanism, and a locking rod. The clamping plate is fixedly connected to the side of the clamping plate, and the fixing rod is fixedly installed on the other side of the connecting seat. The end of the fixing rod is fitted with a connecting plate, and the connecting plate is fixedly installed with a pull ring. The strong elastic limiting mechanism is symmetrically installed on the side of the clamping plate, and the locking rod is fixedly installed at equal intervals on the inner side of the clamping plate.

[0011] Furthermore, the end of the connecting seat is fixedly connected to the outer side of the clamping plate, and the other end of the connecting seat is fixedly connected to the end of the fixing rod. The fixing rod forms a fixed structure with the clamping plate through the connecting seat, and the inner side of the clamping plate is fitted and connected to the side of the first mounting frame.

[0012] Furthermore, the end of the fixing rod is fixedly connected to the end of the connecting plate, and the side of the fixing rod is movably connected to the interior of the L-shaped locking frame.

[0013] Furthermore, the end of the strong elastic limiting mechanism is fixedly connected to the outer side of the clamping plate, and the other end of the strong elastic limiting mechanism is fixedly connected to the inner surface of the L-shaped locking frame. The clamping plate is formed into an elastic structure through the strong elastic limiting mechanism and the L-shaped locking frame.

[0014] This utility model provides a low-resistance, high-efficiency ventilation duct, which has the following beneficial effects:

[0015] 1. This utility model, through the positioning rod and positioning groove, facilitates the initial positioning and docking installation between the second mounting bracket and the first mounting bracket by the operator. Then, the rotation of the connecting shaft within the fixed plate allows the angle of the locking component to be quickly adjusted by the operator, enabling the locking component to quickly lock the first and second mounting brackets together. This improves the efficiency of the operator in disassembling and assembling the ventilation duct, thus avoiding the situation where the operator has to spend a long time disassembling and assembling the duct, which would interfere with the operator's replacement and maintenance efficiency.

[0016] 2. This utility model, through the setting of a powerful elastic limiting mechanism, enables the clamping plate to move towards the inner surface of the L-shaped locking frame when the operator pulls the pull ring outward, thereby completing the unlocking work quickly. This provides convenience for the operator to adjust the angle of the locking component for unlocking. Furthermore, due to the powerful elastic limiting mechanism, the clamping plate can automatically lock when the operator releases the pull ring, thus ensuring that the ventilation pipe will not loosen during use. Moreover, the application of a corrosion-resistant coating makes the inner surface of the stainless steel ventilation pipe body smoother and flatter, thereby reducing the coefficient of friction and lowering wind resistance.

At the same time, a locking component 9 is fixedly connected to the outer surface of the connecting shaft 8.

[0023] like Figures 1-3As shown, the inner surface of the stainless steel ventilation duct body 1 is provided with a corrosion-resistant coating 2, and a first mounting bracket 3 is fixedly installed on the outer surface of the end of the stainless steel ventilation duct body 1.

A second mounting bracket 5 is fixedly installed on the outer surface of the other end of the stainless steel ventilation duct body 1, and a positioning rod 6 is fixedly installed on the side of the second mounting bracket 5. A fixing plate 7 is fixedly installed on the other side of the second mounting bracket 5. A connecting shaft 8 is rotatably connected inside the fixing plate 7, and a locking assembly 9 is fixedly connected to the outer surface of the connecting shaft 8. The locking assembly 9 includes an L-shaped locking frame 91, a connecting sleeve 92, and a clamping and limiting mechanism 93. The connecting sleeve 92 is fixedly installed on the inner surface of the L-shaped locking frame 91. The inner surface of the sleeve 92 is fixedly connected to the outer surface of the connecting shaft 8, and the end of the connecting shaft 8 is rotatably connected to the inner surface of the fixing plate 7. The connecting sleeve 92 and the fixing plate 7 form a rotating structure through the connecting shaft 8. By setting the connecting sleeve 92 and the fixing plate 7 into a rotating structure, the angle of the locking component 9 can be quickly adjusted by the operator. The clamping and limiting mechanism 93 is movably installed on the inner surface of the other side of the L-shaped locking frame 91. The clamping and limiting mechanism 93 includes a clamping plate 931, a connecting seat 932, a fixing rod 933, a connecting plate 934, a pull ring 935, a strong elastic limiting mechanism 936, and a locking rod 937. The connecting seat 932 is fixedly connected to the side of the clamping plate 931, and the other side of the connecting seat 932... A fixing rod 933 is fixedly installed. The end of the connecting seat 932 is fixedly connected to the outer side of the clamping plate 931, and the other end of the connecting seat 932 is fixedly connected to the end of the fixing rod 933. The fixing rod 933 and the clamping plate 931 form a fixed structure through the connecting seat 932. The inner side of the clamping plate 931 is fitted and connected to the side of the first mounting bracket 3. Through the fixed structure of the fixing rod 933 and the clamping plate 931, the clamping plate 931 will not loosen when the fixing rod 933 moves. A connecting plate 934 is installed at the end of the fixing rod 933, and the end of the fixing rod 933 is fixedly connected to the end of the connecting plate 934.

The clamping plate 931 forms an elastic structure through the strong elastic limiting mechanism 936 and the L-shaped locking frame 91. With the clamping plate 931 and the L-shaped locking frame 91 configured as elastic structures, the clamping plate 931 can automatically complete the limiting and locking work when the operator releases the pull ring 935. The inner side of the clamping plate 931 is fixedly installed with locking rods 937 at equal intervals.

[0024] In summary, this low-resistance, high-efficiency ventilation duct is first based on... Figures 1 to 3 As shown in the diagram, the operator inserts the positioning rod 6 into the positioning groove 4 to connect the second mounting bracket 5 and the first mounting bracket 3, thus completing the initial positioning and installation of the two stainless steel ventilation pipe bodies 1. Next, the operator grasps the pull ring 935 and pulls it outward, causing the fixing rod 933 to move the clamping plate 931 towards the inner surface of the L-shaped locking frame 91 via the connecting seat 932. Then, the operator uses the connecting sleeve 92 to rotate the connecting shaft 8 inside the fixing plate 7 to quickly adjust the angle of the L-shaped locking frame 91. When the inner surface of the L-shaped locking frame 91 is against the outer surface of the connection between the first mounting bracket 3 and the positioning groove 4, the pull ring 935 is released, allowing the clamping plate 931 to automatically lock the connection between the first mounting bracket 3 and the second mounting bracket 5 through the rebound force of the strong elastic limiting mechanism 936, thus completing the rapid splicing and installation of the ventilation pipes. At this point, the locking rod 937 automatically inserts into the slot on the outside of the first mounting bracket 3 to complete the locking operation.
