Description

Technical Field

[0001] The utility model belongs to the technical field related to fluid transportation, and particularly relates to an anti-seepage ground air duct joint. Background Technique

[0002] The ground air duct, that is, the ground air supply duct, has a smooth inner wall and small resistance loss. It supplies air under the floor, and the duct and air outlet are embedded under the indoor ground surface. It is commonly used in two-way flow and heat recovery fresh air systems for air supply. The square ultra-thin air supply duct overcomes the disadvantages of the traditional air duct that occupies a large space and has complex on-site installation. Generally, it can be flexibly laid on the ground, wall, ceiling, etc. according to the on-site situation. The connection between the ducts adopts a quick socket structure, with good airtightness, fast and convenient installation, and can greatly save installation costs. Of course, when laying the ground air duct, it must be connected, and joints are inevitably required. However, the related joints still have the following disadvantages in actual use:

[0003] Excluding the duct itself, the most easily damaged part is the joint. If the connection at the joint is not tight enough, not sealed enough, or not firm enough, it may have certain impacts. If the connection at the joint is not sealed enough, it is easy for moisture and the like to penetrate into the duct, and then through the air supply of the duct, it is easy to input humid air into the room, bringing hazards such as germs. Therefore, the airtightness and tightness of the connection at the duct joint need to be ensured;

[0004] After the duct is connected to the joint, the structural strength of the connection part is an important part. Because it needs to be buried under the ground surface and needs to bear a certain pressure, in order to avoid damage to the connection part and cause trouble in later maintenance, the structural strength of the connection part must be sufficient. However, the current socket connection obviously cannot ensure the structural strength at the connection with the joint. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-seepage ground air duct joint, which solves the problems of insufficient tightness at the connection between the duct and the joint, and the inability to effectively guarantee the structural strength at the connection between the duct and the joint by setting a long fixing plate, a short fixing plate, a connecting part, a screw, an adjusting rod, a first reinforcing rib plate, and a second reinforcing rib plate.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is an anti-seepage ground air duct joint, including a joint main body, a long fixing plate, and a short fixing plate. Both ends of the joint main body are fixedly penetrated with connecting parts. Two symmetrically arranged long fixing plates are arranged inside the ports at the ends of the connecting parts away from the joint main body. Bolts are rotatably connected to the mutually facing sides of the two long fixing plates, and the middle parts of the bolts are screwed into the long side edges of the connecting parts;

[0008] The connection parts at both ends of the joint body are used to connect the pipe body. The long fixing plate can be moved up and down by rotating the bolts, and is used to fix the long side of the pipe body.

[0009] The two ends of the two long fixing plates are plugged with left-right symmetrical short fixing plates, and the centers of the two short fixing plates are connected with adjustment rods for common rotation, and the two ends of the adjustment rods penetrate the two short sides of the connecting part;

[0010] The two short fixing plates can move away from or closer to each other by cooperating with the rotation of the adjusting rod, and are used to fix the short side edges of the pipeline body;

[0011] A first reinforcing rib plate is fixed at the outer ends of the two long sides of the connecting portion, and a second reinforcing rib plate is fixed at the outer ends of the two short sides of the connecting portion;

[0012] The provision of reinforcing rib plate 1 improves the structural strength of the long side of the connection, while the provision of reinforcing rib plate 2 strengthens the structural strength of the short side of the connection, so that the connection part ensures good structural strength when connected to the pipeline body, increases pressure resistance, and will not be easily damaged.

[0013] Furthermore, a sealing gasket 1 is fixed to the sides of the two long fixing plates facing away from each other, and sockets are provided through the long fixing plates at both ends of the sealing gasket 1;

[0014] The design of the sealing gasket 1 is that when the long fixed plate contacts the inner wall of the long side of the pipe body, firstly, the long side of the pipe body is locked by the long fixed plate, and secondly, the contact surface can be sealed by the sealing gasket 1 to ensure that there is no penetration of moisture and water vapor as much as possible; and the setting of the socket is to prevent it from being affected by the short fixed plate during the up and down movement.

[0015] Furthermore, a second sealing gasket is fixed to the sides of the two short fixing plates facing away from each other, and the two ends of each short fixing plate are respectively plugged into the sockets at the ends of the two long fixing plates;

[0016] When the long fixed plate moves up and down, both ends of the short fixed plate are in the sockets. Firstly, the positions of the short fixed plate and the long fixed plate are limited, and no rotation occurs, only linear motion occurs. Secondly, even if the long fixed plate and the short fixed plate move synchronously, no collision or intersection occurs. Similarly, the contact surface can be sealed by using the second sealing gasket to ensure that no moisture or water vapor can penetrate as much as possible.

[0017] Furthermore, the surface of the adjusting rod is provided with two symmetrically arranged threaded parts, the thread directions of the two threaded parts are opposite, and the threaded parts are screwed into the short fixing plate;

[0018] The opposite thread part design enables the two short fixing plates to only approach or depart from each other synchronously when the adjusting rod rotates, achieving synchronous locking of the short side of the pipe body.

[0019] Furthermore, one end of the bolt away from the connecting part penetrates through the first reinforcing rib plate, and the threaded part on the surface of the adjusting rod penetrates through the second reinforcing rib plate; this does not affect the installation of the pipe body and ensures the structural strength of the connection.

[0020] Furthermore, the pipe body is inserted into the connecting part, and a first slot is penetrated and opened in the long side of the pipe body near one end of the connecting part, and a second slot is penetrated and opened in the short side of the pipe body near one end of the connecting part.

[0021] Furthermore, the first slot is inserted outside the bolt, the second slot is inserted outside the adjusting rod, and both the long fixing plate and the short fixing plate are located inside the port of the pipe body;

[0022] When installing the pipe body, insert the pipe body into the connecting part. During this process, the position of the first slot corresponds to the bolt, and the position of the second slot corresponds to the adjusting rod, so that they just fit together after insertion. Then adjust the positions of the long fixing plate and the short fixing plate to lock the four sides of the pipe body.

[0023] The utility model has the following beneficial effects:

[0024] By setting the long fixing plate, short fixing plate, connecting part, screw rod, and adjusting rod, the utility model solves the problem of insufficient tightness at the connection between the pipe and the joint; when installing the pipe body, insert the pipe body into the connecting part, and then by rotating the bolt, the two long fixing plates move towards the inner walls of the two long sides of the pipe body respectively until the two long sides of the pipe body are locked and fixed. With the cooperation of the first sealing gasket, the contact surface can be sealed to ensure that moisture and water vapor will not penetrate as much as possible. Similarly, by rotating the adjusting rod, the two short fixing plates can only approach or depart from each other synchronously until the two short fixing plates lock the short sides of the pipe body, thereby realizing the locking and fixing of the four sides and ensuring good tightness.

[0025] By setting the first reinforcing rib plate and the second reinforcing rib plate, the utility model solves the problem that the structural strength at the connection between the pipe and the joint cannot be effectively guaranteed; the setting of the first reinforcing rib plate improves the structural strength of the long side of the connecting part, and the setting of the second reinforcing rib plate strengthens the structural strength of the short side of the connecting part, enabling the connecting part to have good structural strength when connected to the pipe body, increasing the compressive resistance and not being easily damaged.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] Please refer to Figure 1-6 As shown, the present invention is an anti-permeation ground air duct joint, including a joint main body 1, a long fixing plate 2 and a short fixing plate 3. Both ends of the joint main body 1 are fixedly penetrated with connection parts 101. Inside the ports at the ends of the connection parts 101 away from the joint main body 1, there are two long fixing plates 2 symmetrically arranged up and down. On the opposite sides of the two long fixing plates 2, bolts 201 are rotatably connected. The middle parts of the bolts 201 are screwed into the long sides of the connection parts 101;

[0036] The connection parts 101 at both ends of the joint main body 1 are all used for connecting the duct main body 4. By rotating the bolts 201, the long fixing plates 2 can move up and down, which is used for fixing the long sides of the duct main body 4;

[0037] The left and right symmetric short fixing plates 3 are inserted into the two ends of the two long fixing plates 2. The centers of the two short fixing plates 3 are jointly rotatably connected with an adjusting rod 301, and both ends of the adjusting rod 301 penetrate through the two short sides of the connection part 101;

[0038] The two short fixing plates 3 cooperate with the rotation of the adjusting rod 301 to move away from or close to each other, which is used for fixing the short sides of the duct main body 4;

[0039] Reinforcing rib plates I 1011 are fixed at the outer ports of the two long side edges of the connecting part 101, and reinforcing rib plates II 1012 are fixed at the outer ports of the two short side edges of the connecting part 101; the setting of the reinforcing rib plates I 1011 improves the structural strength of the long side edges of the connecting part 101, and the setting of the reinforcing rib plates II 1012 strengthens the structural strength of the short side edges of the connecting part 101, so that the connecting part 101 ensures good structural strength when connected to the pipeline main body 4, increases the compressive resistance, and is not easily damaged.

[0040] Among them, as Figure 1-6 shown, sealing gaskets I 202 are fixed on the mutually facing surfaces of the two long fixing plates 2, and sockets 203 are penetrated and opened in the long fixing plates 2 at both ends of the sealing gaskets I 202;

[0041] The design of the sealing gaskets I 202, when the long fixing plates 2 contact the inner wall of the long side edges of the pipeline main body 4, firstly, the long side edges of the pipeline main body 4 are locked by the long fixing plates 2, and secondly, the contact surfaces can be sealed by the sealing gaskets I 202 to ensure as much as possible that no moisture and water vapor penetrate; the setting of the sockets 203 is to prevent being affected by the short fixing plates 3 during the up and down movement;

[0042] Sealing gaskets II 302 are fixed on the mutually facing surfaces of the two short fixing plates 3, and the two ends of each short fixing plate 3 are respectively inserted into the sockets 203 at the ends of the two long fixing plates 2;

[0043] When the long fixing plates 2 move up and down, the two ends of the short fixing plates 3 are both in the sockets 203. Firstly, the positions of the short fixing plates 3 and the long fixing plates 2 are limited and will not rotate, but only perform linear motion. Secondly, even if the long fixing plates 2 and the short fixing plates 3 move synchronously, no collision and intersection will occur. Similarly, the contact surfaces can be sealed by the sealing gaskets II 302 to ensure as much as possible that no moisture and water vapor penetrate.

[0044] Among them, as Figure 1-4 shown, two symmetrically arranged threaded parts 3011 are arranged on the surface of the adjusting rod 301, the two threaded parts 3011 have opposite thread directions, and the threaded parts 3011 are screwed into the short fixing plates 3; the design of the opposite threaded parts 3011 enables the two short fixing plates 3 to only move synchronously closer to or away from each other when the adjusting rod 301 rotates, realizing synchronous locking of the short side edges of the pipeline main body 4;

[0045] One end of the bolt 201 away from the connecting part 101 penetrates through the reinforcing rib plate I 1011, and the threaded part 3011 on the surface of the adjusting rod 301 penetrates through the reinforcing rib plate II 1012; it does not affect the installation of the pipeline main body 4 and ensures the structural strength of the connection.

[0046] Among them, as Figure 1-5As shown, a pipeline main body 4 is inserted into the connecting part 101. A first slot 401 is penetrated and opened in the long side of one end of the pipeline main body 4 close to the connecting part 101, and a second slot 402 is penetrated and opened in the short side of one end of the pipeline main body 4 close to the connecting part 101;

[0047] The first slot 401 is inserted outside the bolt 201, and the second slot 402 is inserted outside the adjusting rod 301, and both the long fixing plate 2 and the short fixing plate 3 are located inside the port of the pipeline main body 4;

[0048] When installing the pipeline main body 4, insert the pipeline main body 4 into the connecting part 101. During this process, the position of the first slot 401 corresponds to that of the bolt 201, and the position of the second slot 402 corresponds to that of the adjusting rod 301, so that they just fit together after insertion. Then adjust the positions of the long fixing plate 2 and the short fixing plate 3 to lock the four sides of the pipeline main body 4.

[0049] The specific working principle of the present utility model is as follows: When installing the pipeline main body 4, insert the pipeline main body 4 into the connecting part 101. During this process, the position of the first slot 401 corresponds to that of the bolt 201, and the position of the second slot 402 corresponds to that of the adjusting rod 301, so that they just fit together after insertion. Then rotate the bolt 201 to move the two long fixing plates 2 towards the inner walls of the two long sides of the pipeline main body 4 respectively until the two long sides of the pipeline main body 4 are locked and fixed. With the cooperation of the first sealing gasket 202, the contact surface can be sealed to ensure as much as possible that there is no penetration of moisture and water vapor. Then rotate the adjusting rod 301, and the two short fixing plates 3 can only move closer to or away from each other synchronously until the two short fixing plates 3 lock the short sides of the pipeline main body 4. Similarly, with the use of the second sealing gasket 302, the contact surface can be sealed, so as to realize the locking and fixing of the four sides and ensure good tightness.

[0050] The above is only the preferred embodiment of the present utility model, which does not limit the present utility model. Any modification to the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made all fall within the protection scope of the present utility model.
