Description

Technical Field

[0001] The present application relates to the technical field of ventilation duct construction, and in particular to a double-sided socket connection structure of a ventilation duct. Background Art

[0002] The socket-and-plug structure of ventilation ducts is a common connection method used to quickly and firmly connect different sections of ventilation pipes together. This structure usually consists of two parts: a spigot and a socket. The spigot refers to the part of one end of the ventilation duct that is designed to be inserted into the smaller diameter of another pipe. This part is usually smooth to facilitate easy insertion into the socket. The socket is a ring-shaped or cup-shaped area enlarged at the other end of the ventilation duct to receive and secure the spigot of another pipe. There may be a rubber seal or other type of sealing material inside the socket to ensure the airtightness and waterproofness of the connection. During the installation process, the operator needs to align the spigot of one pipe with the socket of the other pipe and apply a certain amount of force to insert it. Once the spigot is fully inserted into the socket, the connection will be secured by a seal or other fastener to ensure the stability and sealing of the pipe connection.

[0003] The advantage of the socket structure is that it provides a quick and simple assembly method, reducing the need for on-site welding, reducing installation costs and time. At the same time, this connection method is easy to disassemble and maintain, and the various parts can be easily separated when cleaning or replacing the pipe.

[0004] However, when the current plug-and-socket structure is used to connect ventilation pipes, each ventilation pipe needs to be processed to form a plug structure and a socket structure. For unit pipes without a plug structure and a socket structure, it is not convenient to connect and install. Utility Model Content

[0005] In order to improve the convenience of connection between ventilation ducts, the present application provides a double-sided socket connection structure for ventilation ducts.

[0006] The present application provides a double-sided socket connection structure for a ventilation duct, which adopts the following technical solution:

[0007] A double-sided socket connection structure of a ventilation duct comprises a first air duct, a second air duct and a connection assembly, wherein the connection assembly comprises a connecting inner cylinder, a first flange and a second flange;

[0008] One end of the connecting inner tube is located in the first air duct, the first flange is sleeved on the tube section of the connecting inner tube located outside the first air duct, one end of the second flange is sleeved on the second air duct, and a socket for inserting the end of the first flange is formed between the inner side wall of the second flange and the end face of the second air duct;

[0009] The connecting inner cylinder is provided with a first fixing member, and the first fixing member is used to connect the first air duct, the connecting inner cylinder and the first flange;

[0010] The second air duct is provided with a second fixing member, and the second fixing member is used to connect the second air duct and the second flange.

By connecting the connecting assembly and the fixing member, the first air duct and the second air duct without the socket structure and the socket structure are connected, which solves the connection problem of the direct connection of the pipeline without the socket structure and the socket interface.

[0012] Optionally, the first flange and the second flange are detachably connected.

[0013] By adopting the above technical solution, the first flange and the second flange are detachably connected, so that the layout of the ventilation duct system can be flexibly adjusted according to needs.

[0026] By adopting the above technical solution, the first flange and the second flange can be locked or unlocked by rotating the locking rod, which makes the operation simpler and more convenient.

[0027] Optionally, a connecting rod is arranged in the installation groove, the connecting rod is passed through the locking rod, the connecting rod is arranged perpendicular to the locking rod, and the connecting rod includes a rod body and a damping sleeve sleeved outside the rod body.

[0028] By adopting the above technical solution, the setting of the damping sleeve increases the friction resistance between the load-bearing rod and the connecting rod, which can make the rotation of the locking rod smoother and less likely to move when not affected by external force, thereby improving the stability of locking or unlocking.

[0029] In summary, the present application includes at least one of the following beneficial effects:

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The present application is further described below with reference to the accompanying drawings:

[0038] Embodiment 1:

[0039] like Figure 1 As shown, this embodiment discloses a double-sided socket connection structure of a ventilation duct, comprising a first air duct 1, a second air duct 2 and a connection assembly 3. The connection assembly 3 is composed of a connection inner tube 31, a first flange 32 and a second flange 33. One end of the connection inner tube 31 is inserted into the first air duct 1, and the first flange 32 is sleeved on the tube section of the connection inner tube 31 located outside the first air duct 1, and one end of the first flange 32 is against the end face of the first air duct 1. Two groups of first fixing members 34 are arranged on the connection inner tube 31, and the two groups of first fixing members 34 are arranged at intervals, and each group of first fixing members 34 includes a plurality of first fixing members 34 arranged at intervals around the circumference of the first air duct 1. Among them, one group of first fixing members 34 is used to connect the first flange 32 and the connection inner tube 31, and the other group of first fixing members 34 is used to connect the first air duct 1 and the connection inner tube 31.

[0040] like Figure 1 and Figure 2 As shown, one end of the second flange 33 is sleeved outside the second air duct 2, and a socket 36 is formed between the inner wall of the second flange 33 and the end surface of the second air duct 2, and the socket 36 is for the end of the first flange 32 away from the first air duct 1 to be inserted. Similarly, a second fixing member 35 is provided on the second air duct 2, and a plurality of second fixing members 35 are provided at intervals around the circumference of the second air duct 2 for connecting the second air duct 2 and the second flange 33.

[0041] The arrangement of the first fixing member 34 and the second fixing member 35 on the first air duct 1 and the second air duct 2 increases the stability and firmness of the connection, and prevents the loosening or falling off problem that may be caused by single-point connection. At the same time, the multi-point fixing method also helps to disperse stress and improve the durability of the overall structure.

[0042] In this embodiment, rivets are used as fixing elements for both the first fixing member 34 and the second fixing member 35. Rivet connection has the advantages of simple structure, reliable connection, good seismic performance, etc., and is suitable for occasions such as ventilation ducts that need to withstand vibration and impact frequently. By firmly connecting the various parts with rivets, the long-term stable operation of the ventilation duct system can be ensured.

[0043] like Figure 2 As shown, the second flange 33 is penetrated by a connecting rod 4. A circular plate-shaped abutting portion 41 is integrally formed at one end of the connecting rod 4, and the abutting portion 41 is used to abut against the second flange 33; and the other end of the connecting rod 4 passes through the first flange 32 and is connected with a locking member 5. In this embodiment, a threaded section 42 is processed on the connecting rod 4, and the locking member 5 includes a locking nut 51 that matches the threaded section 42. By rotating the locking nut 51, it can be moved along the threaded section 42 of the connecting rod 4, thereby realizing the locking and unlocking operations of the connecting rod 4, and then realizing the detachable connection between the first air duct 1 and the second air duct 2. This locking structure is simple and reliable, and is convenient for on-site installation and maintenance.

[0044] The implementation principle of the double-sided socket connection structure of a ventilation duct in Example 1 of the present application is as follows:

[0045] The implementation principle of Example 1 is as follows: a first flange 32, a second flange 33 and a connecting assembly 3 are arranged between the adjacent first air duct 1 and the second air duct 2, so that the connection between the first air duct 1 and the second air duct 2 becomes simple and quick. After the connecting inner cylinder 31 is inserted into the first air duct 1, the first fixing member 34 is used to fix the first air duct 1, the first flange 32 and the connecting inner cylinder 31, and then one end of the connecting inner cylinder 31 is inserted into the second air duct 2, and the second air duct 2 and the second flange 33 are fastened and connected using the second fixing member 35, and the first flange 32 and the second flange 33 are fixedly connected using the connecting rod 4 and the locking member 5 at the left rear, so that the connection between the first air duct 1 and the second air duct 2 can be completed. This method does not require complicated processing of the ventilation duct, which greatly saves installation time and cost.

[0046] Embodiment 2:

[0047] In this embodiment, a mounting groove 43 is formed at one end of the connecting rod 4 away from the abutting portion 41, and the locking member 5 is configured as a locking rod 52. A bearing rod 44 is disposed in the mounting groove 43, and the bearing rod 44 is passed through the middle of the locking rod 52 and is disposed perpendicular to the locking rod 52, so as to realize the rotational connection of the locking rod 52 in the mounting groove 43. After one end of the connecting rod 4 passes through the first flange 32, the locking rod 52 is rotated to rotate the locking rod 52 to be perpendicular or parallel to the connecting rod 4, so that the locking rod 52 can be abutted against or disengaged from the outer side wall of the first flange 32, thereby realizing the locking and unlocking functions.

[0048] The bearing rod 44 specifically includes a rod body 441 and a damping sleeve 442 sleeved outside the rod body 441, and the rod body 441 is fixedly connected to the inner wall of the mounting groove 43. The function of the damping sleeve 442 is to provide a certain damping effect for the bearing rod 44, so that it has a certain damping feeling during the rotation process, thereby preventing misoperation caused by accidental touch. At the same time, the damping sleeve 442 can also protect the bearing rod 44 and the locking rod 52 from wear and corrosion, thereby extending their service life.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
