Description

Technical Field

[0001] This utility model relates to the field of industrial gas supply technology, and in particular to a self-locking multi-hole gas exhaust module. Background Technology

[0002] Existing factory production line workbenches are typically assembled using 28mm diameter lean pipes and various connectors, with workbenches, panels, power strips, and other accessories installed as needed. These workbenches are characterized by their ability to operate independently, be combined, and be easily adjusted, making them suitable for various scenarios such as inspection, maintenance, and product assembly.

[0003] In the production process, compressed air is often used to drive equipment such as actuator cylinders. Therefore, high-pressure air delivery pipelines need to be laid near the workbench. When multiple cylinders or other pneumatic components need to be used simultaneously on a single workbench, multiple delivery pipelines are often required. Due to the lack of a unified distribution and fixing structure, the pipelines easily become tangled and stacked around the workbench, resulting in a messy layout. This not only affects the cleanliness of the operating environment but may also increase problems such as pipeline interference, air leaks, or inconvenient maintenance.

[0004] While some air distributors or connector assemblies exist in the prior art, most have simple structures, a limited number of interfaces, and lack modular installation capabilities with workbenches, making it difficult to meet the multi-point, flexible, and neat compressed air distribution requirements of assembly line operations. Therefore, it is necessary to provide a new air exhaust module structure to address these shortcomings. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] This utility model provides a self-locking multi-hole air exhaust module, comprising: The horizontal exhaust pipe has an internal airflow channel; The gas pipe connectors are located at both ends of the gas exhaust horizontal pipe. Each gas pipe connector has multiple gas interfaces. The gas interfaces are equipped with a self-locking structure to achieve a self-locking connection with the external delivery pipeline. An adapter module is disposed on the outer wall of the horizontal air exhaust pipe. The adapter module protrudes from the side wall of the horizontal air exhaust pipe and is used to install the horizontal air exhaust pipe onto an external workbench.

[0007] Furthermore, each air pipe connector has two gas inlets, giving the air exhaust module a four-hole structure.

[0008] Furthermore, each air pipe connector has three gas ports, giving the entire air exhaust module a six-hole structure, thus allowing connection to six delivery lines.

[0009] Furthermore: one end of the gas pipe connector is provided with multiple gas interfaces with a self-locking quick-connect structure, and the other end is provided with an external thread; both ends of the gas exhaust horizontal pipe are provided with internal threads that mate with the external threads.

[0010] Furthermore, the adapter module is provided with a fan-shaped protrusion, and the two sides of the fan-shaped protrusion form clamping edges for installing external modular clamping connectors.

[0011] Furthermore, the plane containing the clamping edges on both sides of the fan-shaped protrusion coincides with the radial direction of the exhaust pipe.

[0012] Furthermore, the side wall of the exhaust pipe is provided with four sets of adapter modules, which are evenly distributed along the circumference of the exhaust pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: ① Streamlined piping solves the problem of clutter: This utility model achieves centralized compressed air transmission through the airflow channel inside the horizontal exhaust pipe. Combined with the multi-hole design of the air pipe connector (such as four-hole or six-hole structures), the external main air source can be connected to the exhaust module through one pipeline, and then distributed to multiple pneumatic devices through the multi-hole interface, forming an orderly "main-branch" piping layout. Compared with the existing method of directly connecting multiple independent pipelines, this significantly reduces the number of pipelines around the workbench, shortens the length of branch pipelines, effectively avoids pipeline tangling, and improves the utilization rate of the working space and the overall neatness.

[0014] ② Self-locking quick-connect design improves operational efficiency: The gas interface of the air hose connector adopts a self-locking quick-connect structure, allowing for tool-free insertion and removal of external delivery pipelines. The self-locking design ensures a tight seal, preventing compressed air leakage. Simultaneously, the air hose connector and the horizontal air outlet pipe are securely connected via a threaded structure, ensuring a robust and reliable assembly. This connection method not only meets the high-frequency requirements of equipment position adjustments in production but also reduces the complexity of pipeline disassembly and assembly, improving the efficiency of pneumatic equipment debugging and maintenance.

[0015] ③ Versatile installation for flexible scenarios: The adapter module on the outer wall of the air exhaust horizontal pipe can be precisely adapted to the existing lean pipe connectors (external modular clamping joints) on the workbench through the fan-shaped protrusion and clamping edge structure, so as to achieve stable fixation of the air exhaust module; and the four sets of adapter modules evenly distributed along the circumference support installation in multiple directions such as ceiling, side and bottom support, and can flexibly adjust the installation posture of the air exhaust module according to the distribution position of the pneumatic equipment on the workbench, further shortening the branch pipeline length, reducing pressure loss, and ensuring the operational stability of the pneumatic equipment.

[0016] ④ Strong structural compatibility and reduced application costs: The structural design of this utility model is fully compatible with existing production line workbenches assembled with 28mm diameter lean pipes. It can be directly installed without modifying the workbench body. Moreover, the number of holes in the air pipe connector can be flexibly selected according to equipment requirements (such as four holes for three-way equipment, six holes for five-way equipment), adapting to the air source distribution needs of different production scenarios. This avoids the additional costs incurred due to workbench modification or customization of special accessories, and has high economic efficiency and promotional value.

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

[0022] Please see Figures 1 to 4 In this embodiment of the present invention, a self-locking multi-hole air exhaust module includes: The horizontal exhaust pipe 10 has an internal airflow channel 11; Gas pipe connectors 20 are provided at both ends of the gas exhaust horizontal pipe 10. Each gas pipe connector 20 has multiple gas interfaces 21. The gas interfaces 21 are provided with a self-locking structure to achieve a self-locking connection with the external delivery pipeline. The adapter module 30 is disposed on the outer wall of the air exhaust horizontal pipe 10. The adapter module 30 protrudes from the side wall of the air exhaust horizontal pipe 10 and is used to install the air exhaust horizontal pipe 10 onto an external workbench.

[0023] Specifically, existing assembly line workbenches are typically assembled using 28mm diameter lean pipes with a variety of connectors, and fitted with corresponding workbenches, panels, power strips, and other application accessories according to operational needs. These workbenches can be used independently, combined, and easily adjusted, allowing for free design and assembly based on operational requirements. They are suitable for testing, repair, and product assembly in various industries. However, in factory production activities, compressed air is frequently used to drive actuators and other equipment. The transmission of compressed air requires high-pressure air delivery pipelines. When there are many cylinders and other components near a workbench, numerous delivery pipelines are needed, easily leading to clutter around the workbench area. Therefore, improvements are necessary.

[0024] Secondly, this invention features a horizontal air exhaust pipe 10 with an airflow channel 11 inside, allowing compressed air to circulate within it. Two air pipe connectors 20 are then connected to both ends of the horizontal air exhaust pipe 10, enabling direct connection between external compressed air delivery pipelines and the connectors 20. The self-locking structure of the connectors 20 ensures the connection and locking of the delivery pipeline. Furthermore, an adapter module 30 protrudes from the outer wall of the horizontal air exhaust pipe 10, facilitating clamping with existing adapters and ensuring stable installation of the horizontal air exhaust pipe 10 on the workbench. The horizontal air exhaust pipe 10 unifies the arrangement of pipelines near the workbench, allowing equipment requiring compressed air to directly access the pipes through shorter delivery pipelines at the connectors 20 at both ends of the horizontal air exhaust pipe 10, reducing pipeline length and preventing tangled pipelines.

[0025] In one embodiment, the air exhaust module is suitable for installation on a production line workbench assembled from lean pipes and connectors. This workbench can be configured with workbenches, panels, power strips, and other accessories according to operational needs. Since compressed air is frequently used to drive actuators during production, direct pipe connections can easily lead to cluttered piping. This embodiment addresses this by providing an airflow channel 11 inside the horizontal air exhaust pipe 10 and installing air pipe connectors 20 at both ends, allowing external compressed air to be accessed through self-locking interfaces, thereby achieving a unified piping layout.

[0026] like Figure 1 and Figure 2 As shown, preferably, each air pipe connector 20 has two gas interfaces 21, giving the entire air exhaust module a four-hole structure, thereby connecting four delivery pipelines.

[0027] Specifically, in one embodiment, the air pipe connector 20 adopts a dual-interface structure, forming four gas interfaces 21 at both ends of the air exhaust horizontal pipe 10. This facilitates the connection of four delivery pipelines, thereby achieving a one-to-three compressed air distribution to meet the requirement of simultaneously driving three devices. Alternatively, the air pipe connector 20 can have a structure with two gas interfaces 21, forming four gas structures at both ends of the air exhaust horizontal pipe 10, creating a four-hole structure. This facilitates the connection of four delivery pipelines, forming a one-to-three compressed air delivery pipeline, allowing the workbench to access three compressed air lines to drive three devices.

[0028] In another embodiment, each duct connector 20 has three gas ports 21, giving the entire duct module a six-hole structure for connecting six delivery lines.

[0029] Similarly, the air pipe connector 20 adopts a three-port structure, forming a total of six gas ports 21 at both ends of the air exhaust horizontal pipe 10, which can realize a one-to-five compressed air distribution, facilitating the simultaneous supply of air to multiple devices. The air pipe connector 20 can also adopt a structure with three gas ports 21, thus forming a total of six gas structures at both ends of the air exhaust horizontal pipe 10, forming a six-hole structure, which facilitates the connection of six delivery pipelines, forming a one-to-five compressed air delivery pipeline, allowing the workbench to be accessed by five compressed air lines to drive three devices.

[0030] like Figure 2 and Figure 4 As shown, preferably, one end of the tracheal connector 20 is provided with multiple gas ports 21, each gas port 21 is connected to the external delivery pipeline using a self-locking quick-connect structure; the other end of the tracheal connector 20 is provided with an external thread, and both ends of the air exhaust horizontal pipe 10 are respectively provided with internal threads, so that the tracheal connector 20 and the air exhaust horizontal pipe 10 are fixedly connected through the threaded structure.

[0031] Specifically, in a preferred embodiment, the endotracheal connector 20 is securely connected to the internal thread of the horizontal gas exhaust pipe 10 via an external thread; while the multiple gas ports 21 at the other end adopt a self-locking quick-connect structure, facilitating frequent insertion and removal of the delivery pipeline while maintaining good sealing. For installing the endotracheal connector 20, it is preferable to provide an external thread at one end connected to the horizontal gas exhaust pipe 10, while internal threads are provided at both ends of the horizontal gas exhaust pipe 10 corresponding to the external thread. This threaded connection between the external and internal threads securely fixes the endotracheal connector 20 to the horizontal gas exhaust pipe 10.

[0032] Secondly, since the multiple gas ports 21 at the other end of the gas pipe connector 20 need to be frequently plugged and unplugged during production, it is preferable to use a quick-connect gas port 21 with self-locking characteristics, so that the external compressed air delivery pipeline can be easily inserted into the gas port 21 to form a good self-locking sealing connection state.

[0033] like Figures 1 to 3 As shown, preferably, the adapter module 30 is provided with a fan-shaped protrusion 31, which protrudes from the side wall of the air exhaust horizontal pipe 10, thereby forming clamping edges 32 on both sides of the fan-shaped protrusion 31. The clamping edges 32 are used to install external modular clamping connectors, thereby connecting the air exhaust horizontal pipe 10 and the external workbench respectively.

[0034] Specifically, in a preferred embodiment, the horizontal exhaust pipe 10 is cylindrical, with a partial protrusion on its side wall forming a fan-shaped protrusion 31. The clamping edge 32 of the fan-shaped protrusion 31 can be used to hold an external clamping connector, thereby fixing the horizontal exhaust pipe 10 to the workbench or installing other accessories such as a pipeline integration frame. To optimize the shape and size of the horizontal exhaust pipe 10, it is preferable to set the horizontal exhaust pipe 10 as a cylinder, utilizing the cylindrical side wall for corresponding settings. For example, a portion of the side wall can protrude to form a fan-shaped protrusion 31, and the clamping edge 32 of the fan-shaped protrusion 31 can form a connecting part that can be clamped and fixed, allowing the external clamping connector to be clamped to the fan-shaped protrusion 31, thereby installing the horizontal exhaust pipe 10 on the external workbench. Alternatively, other accessories can be installed on the horizontal exhaust pipe 10, such as installing a pipeline integration frame, to further organize the delivery pipeline.

[0035] like Figures 1 to 3 As shown, preferably, the plane where the clamping edges 32 on both sides of the fan-shaped protrusion 31 are located coincides with the radial direction of the air exhaust horizontal pipe 10.

[0036] Specifically, in a preferred embodiment, the clamping edge 32 is positioned on the radial extension line of the cylindrical exhaust horizontal pipe 10 according to the dimensions of the external universal clamping connector, thereby improving clamping stability and aesthetic consistency. To conform to the clamping specifications of the external clamping connector, it is preferable to position the clamping edge 32 according to the corresponding dimensions of the external universal clamping connector. Alternatively, to give the sidewall of the cylindrical exhaust horizontal pipe 10 a more aesthetically pleasing edge and to enhance clamping stability, it is preferable to position the clamping edge 32 on the radial extension line of the cylindrical shape.

[0037] like Figures 1 to 3 As shown, preferably, the side wall of the exhaust horizontal pipe 10 is provided with four sets of transition modules 30, and the four sets of transition modules 30 are evenly distributed along the circumference of the exhaust horizontal pipe 10.

[0038] Specifically, in one embodiment, the four sets of adapter modules 30 can be installed in different directions as needed, thereby achieving ceiling-mounted, lateral, or bottom-mounted fixing, which facilitates shortening the length of the delivery pipeline and maintaining neatness. Alternatively, the fan-shaped protrusions 31 at different positions can be used to install the air exhaust horizontal pipe 10 in different directions, achieving ceiling-mounted, lateral, or bottom-mounted installation. This allows for adaptive installation based on the specific compressed air requirements of the workstation, making the delivery pipeline between the air exhaust horizontal pipe 10 and the compressed air-using equipment as short or as neat as possible.

[0039] Example 1: Four-hole self-locking air vent module (basic example) This embodiment provides a four-hole self-locking air exhaust module, suitable for assembly line workbenches that need to be connected to three pneumatic devices.

[0040] The specific structure is as follows: Air exhaust horizontal pipe 10: adopts an aluminum alloy cylindrical structure with a diameter of 25mm, and forms an airflow channel 11 with a diameter of 17mm through the interior axially. The inner walls at both ends are machined with M20 internal threads.

[0041] Air pipe connector 20: A double-port air pipe connector 20 is installed at each end of the air exhaust horizontal pipe 10. Each connector has an external thread at one end (matching the internal thread of the air exhaust horizontal pipe 10), and two gas ports 21 (diameter 8mm) are symmetrically distributed at the other end. Each gas port 21 has a built-in spring-type self-locking structure. When the external delivery pipeline (8mm diameter PU tube) is inserted, the steel ball in the port is locked against the outer wall of the pipeline by the spring force to achieve self-locking. When the tube is pulled out, the pipeline can be released by pressing the unlocking ring on the outside of the port.

[0042] Adapter module 30: The outer wall of the exhaust horizontal pipe 10 is integrally formed with four sets of fan-shaped protrusions 31 (Adapter module 30), each set of protrusions is distributed at 90° intervals along the circumference; parallel clamping edges 32 are formed on both sides of the fan-shaped protrusions 31, the plane of the clamping edges 32 coincides with the radial direction of the exhaust horizontal pipe 10, and the distance between the two clamping edges 32 is 28mm (for standard lean pipe connectors).

[0043] Assembly and usage process: Two dual-port air pipe connectors 20 are screwed onto both ends of the air outlet horizontal pipe 10 to form four gas ports 21 (four-hole structure). Using the standard lean pipe clamps of the workbench, the air exhaust module is fixed to the side of the workbench frame by clamping it on any set of fan-shaped protrusions 31 and clamping it on the clamping edge 32. The main gas supply pipeline is connected to one of the gas interfaces 21, and the other three interfaces are connected to the three cylinder devices on the workbench, forming a "one-to-three" gas supply distribution path.

[0044] This embodiment achieves centralized gas supply for three devices through a four-hole layout, shortening the pipeline length by more than 60% compared to the traditional method, and increasing the insertion and removal efficiency of the self-locking interface to 5 times that of the traditional threaded connection.

[0045] Example 2: Six-hole self-locking air vent module (extended example) This embodiment optimizes the structure of the air pipe connector 20 based on Embodiment 1 to accommodate more pneumatic devices. The specific differences are as follows: Air tube connector 20: adopts a three-interface structure. Each air tube connector 20 has three gas interfaces 21 (8mm in diameter) distributed in an equilateral triangle at the end away from the air exhaust horizontal tube 10. The interfaces also adopt a self-locking quick-connect structure. The connectors at both ends of the air exhaust horizontal tube 10 form a total of six gas interfaces 21 (six-hole structure).

[0046] The length of the horizontal exhaust pipe 10 is increased by 50mm compared to the first embodiment, while the diameter of the airflow channel 11 remains at 15mm to ensure stable air supply pressure for the six branches.

[0047] Application scenario: Suitable for assembly line workbenches in electronic assembly workshops. This workbench needs to drive five small pneumatic grippers (8mm diameter pipes) simultaneously. The six-hole structure realizes the "one-to-five" air source distribution. After the main air source is connected, the remaining five interfaces are connected to the gripper devices respectively. With the side-mounted adapter module 30, the pipe length of each device is controlled within 30cm, completely avoiding pipe crossing.

[0048] Example 3: Multi-directionally installed four-hole air exhaust module (optimized installation method example) This embodiment focuses on demonstrating the multi-directional installation characteristics of the adapter module 30. Its structure is basically the same as in Embodiment 1, the difference being the installation method: Ceiling mount: Select a set of fan-shaped protrusions 31 at the top of the air exhaust horizontal pipe 10 and fix them to the top beam of the workbench frame through lean pipe connectors. The gas interface 21 faces downwards and is compatible with pneumatic equipment suspended below the workbench. Bottom-mounted installation: The air exhaust module is fixed to the support beam under the workbench using the fan-shaped protrusion 31 at the bottom, with the interface facing upwards, which facilitates connection to the equipment on the workbench. Combined installation: Two sets of vertical fan-shaped protrusions 31 are used simultaneously to fix the air exhaust module at the corner of the workbench through corner bracket connectors, so as to provide air supply to the equipment from both directions.

[0049] This embodiment uses four sets of circumferentially distributed adapter modules 30 to allow the air exhaust module to be flexibly adjusted in terms of installation angle according to the equipment layout, minimizing pipe bends and reducing pressure loss to less than 5% (the pressure loss of traditional distributed pipelines is about 15-20%).

[0050] The above embodiments fully demonstrate the technical solution of this utility model from the perspectives of basic structure, extended functions and installation methods. The structural features of each embodiment can be combined and applied according to actual needs, and can achieve the technical effects of neat pipeline, convenient connection and stable installation.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
