Description

Technical Field

[0001] This utility model relates to the technical field of gas distribution devices, and in particular to a multi-hole uniform gas outlet structure for a gas distribution rod. Background Technology

[0002] In industrial automated production lines, cleaning and purging, or material cooling applications, air distribution rods are often used. The main function of the air distribution rod is to evenly distribute and blow the gas from the autonomous air source to the designated area through multiple orifices or nozzles on the rod body.

[0003] Currently, the connection between the gas distributor and the main gas source pipeline is fundamental to its function, and most existing connection methods use traditional threaded or flanged connections. While this connection method can ensure a certain degree of sealing and firmness during initial installation, its structure is fixed and rigid, making disassembly and assembly very cumbersome.

[0004] In situations requiring regular maintenance, unclogging, or rapid replacement of different specifications of the gas distributor rod to meet varying production needs, the drawbacks of threaded or flanged connections become glaringly apparent. Operators must use specialized tools and spend considerable time disassembling and reinstalling, severely impacting production continuity and maintenance efficiency, and increasing labor costs.

[0005] Furthermore, existing gas distributors have shortcomings in achieving uniform gas output and facilitating equipment installation. On the one hand, simple pipe openings can lead to uneven gas flow within the pipe, resulting in significant differences in gas pressure and flow rate between near and far orifices. On the other hand, the installation and fixation of the gas distributor itself usually requires additional clamps or supports, making the overall structure complex and inconvenient to install. Therefore, the market urgently needs a structure that can achieve both quick assembly and disassembly, while ensuring uniform gas output and convenient installation.

[0006] Therefore, this utility model proposes a multi-hole uniform air outlet structure for the air distribution rod to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of the existing gas distribution rod multi-hole uniform gas outlet structure, such as cumbersome and time-consuming connection and disassembly with the main gas source pipeline, reliance on complex fasteners for sealing performance, and inconvenient installation, this utility model aims to provide a gas distribution rod multi-hole uniform gas outlet structure with improved structure that can effectively solve the above problems.

[0008] This utility model provides a multi-hole uniform air outlet structure for a gas distribution rod, including: a connecting sleeve and a connecting tube that can be plugged into the connecting sleeve; it also includes a uniform air outlet mechanism fixed inside the connecting sleeve and a fixing mechanism disposed on the connecting tube.

[0009] The fixing mechanism includes a square groove set on the connecting pipe, a pressing plate rotatably connected in the square groove, and a rubber block set in the connecting pipe and abutting against one end of the pressing plate. A locking block is fixedly connected to the other end of the pressing plate. The uniform air outlet mechanism includes a T-shaped pipe, and multiple air distribution pipes are evenly distributed along the length of the T-shaped pipe on the rear side.

[0010] Furthermore, the outer wall of the connecting sleeve is provided with an extension plate along the axial direction of the connecting sleeve. In the combined state, the pressing plate rotates under the rebound force of the rubber block, causing the locking block to engage with the extension plate of the connecting sleeve, thereby locking the connecting tube into the connecting sleeve.

[0011] Preferably, H-shaped blocks are fixed on both sides of the T-shaped tube of the uniform air outlet mechanism. The H-shaped blocks are provided with mounting hole one and mounting hole two. The structure is used to conveniently install and fix the entire air distribution rod device to external equipment, which improves the integration and installation convenience.

[0012] Preferably, as a specific combination method, the H-shaped block is a block with a central through hole, and the left and right ends of the T-shaped tube are respectively inserted into and fixed in the central through hole of the corresponding H-shaped block. This insertion and fixing method has a stable structure and is easy to process and assemble.

[0013] Preferably, the locking block of the fixing mechanism is located at the opposite end of the pressing plate to the end that abuts against the rubber block, forming an efficient lever structure that allows the pressing action to reliably drive the locking block to lift and reset.

[0014] Preferably, as a specific implementation of the unlocking operation, when the pressing plate is pressed from the outside, one end of the pressing plate compresses the rubber block, and the locking block at the other end is lifted due to the lever action, thereby separating from the extension plate, realizing quick unlocking, and the operation is in line with ergonomic intuition.

[0015] Preferably, to ensure airtightness, the structure also includes a sealing ring, which is disposed around the outer wall of the connecting pipe. When the connecting pipe is inserted into the connecting sleeve, the sealing ring is compressed and forms a circumferential elastic seal with the inner wall of the connecting sleeve, effectively preventing gas leakage.

[0016] Preferably, the main body of the T-shaped tube is arranged radially along the connecting sleeve, while multiple air distribution tubes are evenly distributed axially along the connecting sleeve. This spatial layout is conducive to the formation of a stable buffer zone after the airflow enters the T-shaped tube, thereby distributing it more evenly to each air distribution tube.

[0017] Preferably, to ensure smooth insertion and automatic locking, the outer wall of the extension plate of the connecting sleeve has a guide slope. When the connecting tube is inserted, the locking block will first contact and slide smoothly along the guide slope, automatically completing the compression of the rubber block and the final locking action without any additional operation.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model solves the problems of complex, time-consuming, and tool-intensive operation in connecting the gas source pipe and the gas distribution rod in the prior art by setting a lever-buckle fixing mechanism consisting of a pressing plate, a locking block, a rubber block, and an extension plate. It achieves the technical effect of automatically locking when the connecting pipe is inserted, unlocking by simply pressing the pressing plate when disassembling, making the operation extremely simple and quick, and greatly improving work efficiency.

[0020] 2. This utility model solves the problems of uneven gas distribution and difficulty in integrating and fixing the gas distribution rod device with external equipment in the prior art by setting a T-shaped tube and evenly distributing multiple gas distribution tubes on the rear side of the T-shaped tube, and setting H-shaped blocks with mounting holes at both ends of the T-shaped tube. It achieves the technical effect of uniform gas distribution and compact overall structure of the device, which is easy to install stably on the equipment.

[0021] 3. This utility model solves the problem of sealing failure and gas leakage caused by vibration or pressure fluctuations in the existing quick-plug structure by setting a sealing ring on the outer wall of the connecting pipe and utilizing the elastic deformation of the sealing ring in the connecting sleeve, combined with the axial locking force of the fixing mechanism. It achieves the technical effect of simple sealing structure, high airtightness, safety and reliability under the premise of quick disassembly and assembly. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 4 This utility model provides a multi-hole uniform air outlet structure for the air distribution rod, which aims to solve the problems of inconvenient connection and disassembly of the air source pipe, unreliable sealing, and complicated installation and fixing of the air distribution rod in the prior art.

[0031] like Figure 1 and Figure 2 As shown, the multi-hole uniform gas outlet structure of the gas distributor includes a connecting sleeve 1. An extension plate 406 is provided on the outer wall of the connecting sleeve 1 along its axial direction. The connecting sleeve 1 is used to install and accommodate the uniform gas outlet mechanism 2. A connecting pipe 3 is detachably fitted into the connecting sleeve 1 and is used to introduce gas. The uniform gas outlet mechanism 2 is fixed to the inner side of the connecting sleeve 1 and is used to uniformly distribute and discharge the gas. A fixing mechanism 4 is provided on the connecting pipe 3 and is used to lock the connecting pipe 3 to the connecting sleeve 1. Figure 2 and Figure 3 As shown, the uniform gas discharge mechanism 2 includes a T-shaped tube 201, which is fixed to the inner side of the connecting sleeve 1. The main body of the T-shaped tube 201 is arranged radially along the connecting sleeve 1. Multiple gas distribution pipes 202 are evenly distributed along the length of the T-shaped tube 201 on its rear side. These multiple gas distribution pipes 202 are evenly distributed along the axial direction of the connecting sleeve 1. Gas is evenly discharged from the multiple gas distribution pipes 202 through the T-shaped tube 201. Figure 3 and Figure 4 As shown, H-shaped blocks 203 are fixed on both the left and right sides of the T-shaped tube 201. The H-shaped block 203 is a block with a central through hole. The left and right ends of the T-shaped tube 201 are respectively inserted into and fixed in the central through hole of the H-shaped block 203. The H-shaped block 203 is provided with mounting hole one 204 and mounting hole two 205. Mounting hole one 204 and mounting hole two 205 are used to fix the entire uniform air outlet mechanism 2 to the external equipment.

[0032] Please refer to Figure 2 , Figure 3 and Figure 4 The uniform air outlet mechanism 2 has a T-shaped tube 201. Multiple air distribution tubes 202 are evenly distributed along the length of the rear side of the T-shaped tube 201. H-shaped blocks 203 are fixedly connected to both the left and right sides of the T-shaped tube 201. The upper side of the H-shaped block 203 is provided with mounting hole 1 204 and mounting hole 205.

[0033] The uniform gas outlet mechanism 2 is fixedly connected to the inner wall of the connecting sleeve 1 by welding or integral molding. Its function is to collect the gas from the connecting pipe 3 and distribute it evenly through multiple gas distribution pipes 202 and discharge it. At the same time, the mounting hole 1 204 and the mounting hole 205 are used to fix the connecting sleeve 1 and the uniform gas outlet mechanism 2 to the external equipment.

[0034] The outlet end of the connecting pipe 3 is inserted into the connecting sleeve 1 and approaches the inlet of the T-shaped pipe 201 of the uniform gas outlet mechanism 2. In the assembled state, the connecting pipe 3 and the connecting sleeve 1 are locked and sealed by the fixing mechanism 4 described later, forming a connected gas flow channel. This structure, which integrates the gas source pipeline and the gas distribution mechanism into one unit, ensures that the gas can be efficiently and stably transported from the connecting pipe 3 to the uniform gas outlet mechanism 2 for distribution.

[0035] For the setup of gas source equipment used to provide gas, those skilled in the art can use various conventional methods such as compressors and gas storage tanks. The specific connection methods are well-known technologies in the field and will not be described in detail here.

[0036] As a preferred embodiment, please refer to Figure 3 and Figure 4 H-shaped blocks 203 are fixed on both the left and right sides of the T-shaped tube 201. The H-shaped block 203 is a block with a central through hole. The left and right ends of the T-shaped tube 201 are respectively inserted into and fixed in the central through hole of the H-shaped block 203. The H-shaped block 203 is provided with mounting hole one 204 and mounting hole two 205. Mounting hole one 204 and mounting hole two 205 are used to fix the entire uniform air outlet mechanism 2 together with the connecting sleeve 1 to the external equipment.

[0037] In a preferred embodiment, the main body of the T-tube 201 is arranged radially along the connecting sleeve 1, while the multiple gas distribution pipes 202 are evenly distributed axially along the connecting sleeve 1. This arrangement is conducive to the smooth transition of gas in the T-tube 201 and the even distribution to the multiple gas distribution pipes 202.

[0038] As a preferred embodiment, please refer to Figure 4 The locking block 404 is located on the opposite end of the pressing plate 403 from the end that is abutted by the rubber block 405. When it is necessary to disassemble the connecting pipe 3, the pressing plate 403 is pressed externally, and the end of the pressing plate 403 that abuts against the rubber block 405 will squeeze the rubber block 405. The other end of the pressing plate 403 with the locking block 404 is lifted due to the lever action, so that the locking block 404 is separated from the extension plate 406.

[0039] In a preferred embodiment, in order to achieve rapid automatic locking, the outer wall of the extension plate 406 has a guide slope. When the connecting tube 3 is inserted into the connecting sleeve 1, the locking block 404 first contacts and slides along the guide slope, forcing the pressing plate 403 to rotate and compress the rubber block 405 until the locking block 404 passes over the extension plate 406 and is locked onto the locking surface of the extension plate 406 under the action of the rebound force of the rubber block 405.

[0040] In a preferred embodiment, to ensure the airtightness of the connection, the porous uniform air outlet structure of the air distribution rod also includes a sealing ring 401. The sealing ring 401 is arranged around the outer wall of the connecting pipe 3 and forms a reliable seal with the inner wall of the connecting sleeve 1 when the connecting pipe 3 is sleeved in the connecting sleeve 1.

[0041] Working principle: During connection, the connecting tube 3 is inserted into the connecting sleeve 1. The sealing ring 401 on the outer wall of the connecting tube 3 contacts and is compressed against the inner wall of the connecting sleeve 1, forming a reliable gas seal. During insertion, the locking block 404 on the fixing mechanism 4 contacts the guide slope of the extension plate 406 on the connecting sleeve 1. The locking block 404 slides along the guide slope, forcing the pressing plate 403 to rotate around the rotation point in the square groove 402. The other end of the pressing plate 403 then squeezes the rubber block 405. When the connecting tube 3 is inserted into place, the locking block 404 passes over the extension plate 406. At this time, the compressed rubber block 405 rebounds. The elastic force of the rubber block 405 drives the pressing plate 403 to rotate in the opposite direction, so that the locking block 404 is firmly locked onto the extension plate 406, realizing the quick and automatic locking of the connecting tube 3 and the connecting sleeve 1.

[0042] Gas enters through connecting pipe 3, flows through the internal cavity of connecting sleeve 1, and enters the uniform gas outlet mechanism 2 fixed inside the connecting sleeve 1; the gas first enters T-shaped pipe 201, and is buffered and split within T-shaped pipe 201, and then is evenly discharged from multiple gas distribution pipes 202 evenly distributed along the length of T-shaped pipe 201 from the rear side of T-shaped pipe 201; the entire device can be fixed to external equipment through mounting holes 204 and 205 on the H-shaped blocks 203 on the left and right sides of T-shaped pipe 201;

[0043] When disassembly is required, press the pressing plate 403. One end of the pressing plate 403 will squeeze the rubber block 405 again. The other end of the rubber block 405, which has a locking block 404, will be lifted due to the lever action, so that the locking block 404 will disengage from the extension plate 406. At this time, keep pressing and the connecting tube 3 can be pulled out from the connecting sleeve 1. The operation is simple and quick.
