Description

Technical Field

[0001] This utility model belongs to the field of ventilation structure technology, and in particular relates to a ventilation structure for a factory refrigeration system. Background Technology

[0002] In factory applications, ventilation ducts are often used to transport air and guide the low-temperature airflow generated by the air cooler to a designated location for cooling. During the construction of ventilation ducts, due to some special circumstances, flexible connecting pipes are required to ensure that the ducts can be arranged normally. At the same time, connecting with flexible connecting pipes can also reduce the transmission of vibration to a certain extent.

[0003] When connecting flexible pipes to ventilation ducts, the traditional method often uses bolts, which takes time and reduces installation efficiency, thus affecting the overall construction efficiency. To solve this problem, there is an urgent need for a ventilation structure for factory refrigeration systems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of reduced installation efficiency caused by connecting ventilation pipes and flexible connecting pipes with bolts, and to propose a ventilation structure for a factory refrigeration system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ventilation structure for a factory refrigeration system, comprising a ventilation pipe, one end of which is provided with a flexible connecting pipe; a fixing component located outside the connection between the ventilation pipe and the flexible connecting pipe; and a connecting component located inside the fixing component. The fixing component includes a mounting frame, on which an extrusion strip is slidably mounted through a groove. An extrusion frame is slidably mounted on one side of the mounting frame. A first connecting post is rotatably mounted on the mounting frame through a through hole at one end. An extrusion block is fixedly mounted on the outer wall of the first connecting post. A sliding plate is slidably mounted on the extrusion block through a groove at its bottom end. A plug rod is fixedly mounted on one side of the sliding plate, and a spring is fixedly mounted on one end of the sliding plate.

[0006] As a further description of the above technical solution: The spring is located inside the extrusion block and one end is fixedly connected to the extrusion block. The insertion rod is slidably connected to the mounting frame through a groove opened on the inner side of the mounting frame.

[0007] As a further description of the above technical solution: The extrusion frame is located between the extrusion strip and the mounting frame, and the side of the extrusion strip that contacts the extrusion frame is an inclined surface.

[0008] As a further description of the above technical solution: The mounting frame is located on the outside of the connection between the flexible connecting pipe and the ventilation pipe. Limiting strips are provided on both sides of the extrusion strip, and a corresponding sliding groove is provided on the inner side of the mounting frame.

[0009] As a further description of the above technical solution: The connecting assembly includes a sliding sleeve, one end of which is fixedly mounted with a top block, and the top block is rotatably mounted with a second connecting column through a groove opened therein.

[0010] As a further description of the above technical solution: A limit block is fixedly installed at one end of the second connecting column, and a torsion spring is fixedly installed on the outer wall of the second connecting column. The other end of the torsion spring is fixedly connected to the top block.

[0011] As a further description of the above technical solution: A push rod is slidably installed inside the sliding sleeve, and a limit post is fixedly installed on the outer wall of the push rod. The limit post is slidably connected to the sliding sleeve through a limit groove opened inside the sliding sleeve.

[0012] As a further description of the above technical solution: The mounting frame and the extrusion frame are both fixedly connected to one side with a top rod, and the sliding sleeve is slidably connected to both through the through holes opened in the ventilation pipe and the flexible connecting pipe.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, a fixing component is provided inside. This design allows for easy connection between the ventilation duct and the flexible connector. Simply place the mounting frame at the connection point and insert the compression frame into the mounting frame. The compression frame then compresses the compression strip, causing it to move and compress the connection point. Simultaneously, the compression frame and the mounting frame also compress the connection point, ensuring a tight connection between the ventilation duct and the flexible connector. Furthermore, the compression block can limit and fix the compression frame, and inserting a rod into the mounting frame prevents the compression block from moving, thus ensuring the stability of the compression frame during use and ensuring a tight connection between the ventilation duct and the flexible connector.

[0014] In this invention, a connecting component is provided inside. This design allows the sliding sleeve to be inserted into the corresponding through hole at the connection point of the ventilation pipe and the flexible connecting pipe when the ventilation pipe and the flexible connecting pipe are fixed by the mounting frame and the compression frame. The insertion of the sliding sleeve increases the connection between the fixing component and the ventilation pipe, thus preventing the mounting frame from slipping off the connection point. At the same time, the ventilation pipe blocks the sliding sleeve, so that when the mounting frame and the compression frame gradually compress the connection point, the top rod can be moved. The top rod drives the limiting block to rotate, and one end of the limiting block contacts the inner wall of the ventilation pipe. This allows the fixing component to be further connected to the ventilation pipe, thus ensuring the stability of the fixing component in use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In its specific implementation, such as Figures 1-5This utility model provides a technical solution: a ventilation structure for a factory refrigeration system, including a ventilation pipe 1, one end of which is provided with a flexible connecting pipe 2; a fixing component 3, which is located on the outside of the connection between the ventilation pipe 1 and the flexible connecting pipe 2; and a connecting component 4, which is located on the inside of the fixing component 3. The fixing component 3 includes a mounting frame 31, on which an extrusion strip 33 is slidably mounted through a groove. An extrusion bracket 32 ​​is slidably mounted on one side of the mounting frame 31. A first connecting post 38 is rotatably mounted on the mounting frame 31 through a through hole at one end. An extrusion block 37 is fixedly mounted on the outer wall of the first connecting post 38. A sliding plate 35 is slidably mounted on the extrusion block 37 through a groove at its bottom end. A plug rod 34 is fixedly mounted on one side of the sliding plate 35. One end of the sliding plate 35 is fixedly mounted... A spring 36 is fixedly installed inside the extrusion block 37, with one end fixedly connected to the extrusion block 37. The insertion rod 34 is slidably connected to the mounting frame 31 through a groove opened on the inner side of the mounting frame 31. The extrusion frame 32 is located between the extrusion strip 33 and the mounting frame 31. The side of the extrusion strip 33 that contacts the extrusion frame 32 is an inclined surface. The mounting frame 31 is located outside the connection between the flexible connecting pipe 2 and the ventilation pipe 1. Limiting strips are provided on both sides of the extrusion strip 33, and corresponding sliding grooves are provided on the inner side of the mounting frame 31.

[0023] During installation, first connect both ends of the flexible connecting pipe 2 to one end of the ventilation pipe 1 to be connected. Then, place the mounting frame 31 at the overlapping part of the ventilation pipe 1 and the flexible connecting pipe 2, and insert the compression frame 32 into the mounting frame 31, so that the compression frame 32 is located between the compression strip 33 and the mounting frame 31. As the compression frame 32 extends, the compression strip 33 can gradually compress the connection between the flexible connecting pipe 2 and the ventilation pipe 1. At the same time, the mounting frame 31 and the compression frame 32 can also compress the connection, thereby ensuring that the flexible connecting pipe 2 can be tightly connected to the ventilation pipe 1. Then, rotate the compression block 37 so that one side contacts the compression frame 32. At the same time, pull the sliding plate 35 to move the insertion rod 34 and stretch the spring 36. When the compression block 37 rotates to a certain position, insert the insertion rod 34 into the groove opened inside the mounting frame 31 to fix the compression block 37. At the same time, the compression of the compression frame 32 by the compression block 37 can prevent the compression frame 32 from moving. like Figure 5As shown, the connecting assembly 4 includes a sliding sleeve 45. A top block 41 is fixedly installed at one end of the sliding sleeve 45. A second connecting post 43 is rotatably installed on the top block 41 through a groove opened inside it. A limit block 44 is fixedly installed at one end of the second connecting post 43. A torsion spring 42 is fixedly installed on the outer wall of the second connecting post 43. The other end of the torsion spring 42 is fixedly connected to the top block 41. A top rod 47 is slidably installed inside the sliding sleeve 45. A limit post 46 is fixedly installed on the outer wall of the top rod 47. The limit post 46 is slidably connected to the sliding sleeve 45 through a limit groove opened inside the sliding sleeve 45. The mounting frame 31 and the extrusion frame 32 are both fixedly connected to one side of the top rod 47. The sliding sleeve 45 is slidably connected to the ventilation pipe 1 and the flexible connecting pipe 2 through through holes opened inside them. When the mounting frame 31 is installed at the connection between the ventilation pipe 1 and the flexible connecting pipe 2, the sliding sleeve 45 is aligned with the through hole at the connection and inserted into the through hole as the mounting frame 31 moves. As the mounting frame 31 and the pressing frame 32 gradually press inward, the sliding sleeve 45 stops moving due to the obstruction of the ventilation pipe 1 and the flexible connecting pipe 2, while the push rod 47 moves with the movement of the mounting frame 31 and the pressing frame 32. This push rod 47 presses the limiting block 44, causing the limiting block 44 to rotate and be released from the top. One side of block 41 extends out, which allows the torsion spring 42 to deform and allows one end of the limiting block 44 to contact the inner wall of the ventilation pipe 1 for further limiting. When disassembling, the top rod 47 extends outward as the mounting frame 31 and the compression frame 32 move and gradually separates from the limiting block 44, so that the limiting block 44 retracts back into the top block 41 under the action of the torsion spring 42, and the sliding sleeve 45 can be removed from the through hole at the connection between the ventilation pipe 1 and the flexible connecting pipe 2, thus completing the separation.

[0024] Working principle: During installation, firstly, connect both ends of the flexible connecting pipe 2 to one end of the ventilation pipe 1 to be connected. Then, place the mounting frame 31 at the overlapping position of the ventilation pipe 1 and the flexible connecting pipe 2, and align the sliding sleeve 45 with the through hole at the connection point. As the mounting frame 31 moves, it is inserted into the through hole at the connection point. Then, place the mounting frame 31 at the overlapping position of the ventilation pipe 1 and the flexible connecting pipe 2, thereby inserting the compression frame 32 into the mounting frame 31, so that the compression frame 32 is located between the compression strip 33 and the mounting frame 31. As the compression frame 32 extends, the compression strip 33 can gradually compress the connection between the flexible connecting pipe 2 and the ventilation pipe 1. At the same time, the mounting frame 31 and the compression frame 32 can also compress the connection point, thereby ensuring that the flexible connecting pipe 2 can be tightly connected to the ventilation pipe 1. Then, by rotating the compression block 37 so that one side contacts the compression frame 32, and at the same time, pull the sliding plate 35 to move the insertion rod 34 and stretch the spring 36. Thus, when the compression block 37 rotates to a certain position... When the insert rod 34 is inserted into the groove opened inside the mounting frame 31, the extrusion block 37 is fixed. At the same time, the extrusion frame 32 is prevented from moving by the extrusion block 37. When the mounting frame 31 and the extrusion frame 32 are pressed and fixed, the sliding sleeve 45 stops moving due to the obstruction of the ventilation pipe 1 and the flexible connecting pipe 2, while the push rod 47 moves with the movement of the mounting frame 31 and the extrusion frame 32. Thus, the push rod 47 presses the limiting block 44, causing the limiting block 44 to rotate and be released from the push rod. One side of 41 extends outward, which allows the torsion spring 42 to deform and the limiting block 44 to contact the inner wall of the ventilation pipe 1, thereby further limiting it. When disassembling, the top rod 47 extends outward as the mounting frame 31 and the pressing frame 32 move and gradually separates from the limiting block 44, so that the limiting block 44 retracts back into the top block 41 under the action of the torsion spring 42, and the sliding sleeve 45 can be taken out from the through hole at the connection between the ventilation pipe 1 and the flexible connecting pipe 2, thus completing the separation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
