Description

Technical Field

[0001] This utility model relates to an air supply component for a workbench, belonging to the field of workbench accessories. Background Technology

[0002] Workshop workbenches are specialized equipment used in workshop production operations, with diverse classification methods and functional characteristics. They combine assembly systems, workpiece fixtures, and online assembly and testing equipment to meet the assembly and production needs of a variety of products.

[0003] The existing air supply components for workbenches typically consist of an air inlet pipe fixed to the workbench, with one end connected to the air source and the other end directly inserted into a tightly fitted air hose to ventilate the workpiece. To improve the utilization rate of the air source, two air outlets are provided at the end of the air inlet pipe. However, under prolonged use, the air hose may come loose from the end of the air inlet pipe due to air pressure, affecting normal use and work for personnel. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a gas supply component for a workbench.

[0005] An air supply assembly for a workbench includes an air inlet pipe with air inlet connectors fixedly connected to both sides. One of the air inlet connectors is used to connect to an air source. The air inlet pipe also has an air outlet connector with at least one outlet. The air inlet pipe's fixed connection of the air inlet and outlet connectors avoids the loosening problem caused by air pressure fluctuations when directly plugging in traditional air hoses, significantly improving the reliability and stability of the air source connection. The air inlet pipe has at least one outlet connector, allowing for multiple outlets to be configured according to actual needs, achieving multi-purpose use of a single air source, improving air source utilization efficiency, and meeting the needs of simultaneously supplying air to multiple workstations or multiple pneumatic devices. This utility model has a compact structure and an integrated air inlet and outlet interface, facilitating installation and maintenance. It is suitable for various workshop workbench environments, and is particularly adaptable to multi-variety, small-batch assembly operations.

[0006] Preferably, both the air inlet and outlet connectors are fixedly installed on the air receiving pipe via threaded connections. This threaded connection ensures a tight engagement between the contact surfaces of the air inlet and outlet connectors and the air receiving pipe. Combined with sealing rings or gaskets, this significantly improves the airtightness at the interface, further reducing the risk of leakage. The overall assembly is comprehensively optimized in terms of air source utilization efficiency, connection reliability, and ease of daily maintenance, making it more suitable for high-intensity, long-cycle workshop operating environments.

[0007] Preferably, the air outlet connector is located at the bottom of the air inlet pipe. Positioning the air outlet connector at the bottom allows for efficient routing of the air outlet hose or quick-connect fitting along the underside of the workbench, avoiding congestion on the front and sides and improving the overall flexibility of the workbench layout. With the air outlet at the bottom, the air pipe status is readily apparent, making it easier for operators to detect hose connections and airflow direction, facilitating the timely detection of any loose connections or potential leaks, and ensuring safe production in the workshop.

[0008] Furthermore, the air outlet connector can be a one-way connector, a two-way connector, or a three-way connector. The number of branches can be freely selected according to the actual workstation requirements, enabling flexible allocation of single, dual, or triple air sources to meet the simultaneous air supply needs of different tooling or fixtures. For applications requiring only one air source, a one-way connector can be used to save materials and costs; for applications requiring multiple air sources, two-way or three-way connectors can be selected, eliminating the need for additional distributors or branch pipes, thereby reducing procurement and maintenance costs.

[0009] Preferably, the air inlet pipe is further provided with a connecting component. The air inlet pipe has a protruding connecting flange on its exterior. The connecting component includes an upper adjusting block and a lower adjusting block that is adjustablely connected to the upper adjusting block via bolts. The upper and lower adjusting blocks cooperate to form a first locking groove and a second locking groove. The first locking groove is used to engage with the connecting flange, and the second locking groove is used to engage with a protrusion on the worktable. The engagement of the locking grooves with the connecting flange and the protrusion on the worktable achieves a "click-lock" type fixation, allowing for quick positioning without additional bolts or special tools, shortening installation and disassembly time, and improving on-site work efficiency. The double locking groove structure can lock both the pipe body itself and the worktable protrusion, forming dual positioning and locking, significantly enhancing the component's vibration resistance and anti-loosening reliability, and ensuring stability during long-term operation. The upper and lower adjusting blocks can be disassembled, replaced, or fitted with anti-loosening washers individually. When wear occurs or readjustment is required, maintenance can be completed by loosening only a few bolts, without overall disassembly, making on-site maintenance and repair more convenient.

[0010] Furthermore, the connecting protrusion is fan-shaped, with a smaller inner edge and a larger outer edge, and the first and second connecting grooves are fan-shaped to mate with the connecting protrusion. This fan-shaped engagement has a natural conical guiding effect, allowing the upper and lower adjusting blocks to be quickly "guided" into the correct position during assembly, automatically achieving precise alignment of the angle and center, reducing the number of adjustments and assembly errors. During bolt tightening, the fan-shaped engagement surface has a slight wedging effect, which can further enhance the radial clamping force under axial force, ensuring a firm fit between the air pipe and the connector.

[0011] Furthermore, the second snap-fit ​​groove is fixedly connected to a connecting protrusion, and a fixing protrusion is provided on the other side of the connecting protrusion. The fixing protrusion is used to fixally connect with the slide rail on the worktable. After the fixing protrusion engages with the worktable slide rail, it can achieve precise horizontal movement and positioning under the guidance of the slide rail, meeting the needs of rapid adjustment between different workstations and improving layout flexibility. The size of the fixing protrusion can be customized according to the width and shape of the slide rail, compatible with common industrial slide rails such as T-type and U-type. By utilizing the cooperation between the slide rail and the fixing protrusion, it is only necessary to loosen the upper and lower adjusting block bolts, slide along the slide rail to the desired position, and then re-lock, which greatly shortens the adjustment time and improves on-site efficiency.

[0012] Furthermore, the fixing protrusion is fixedly connected to the connecting protrusion via bolts passing through the slide rail on the worktable, thus fixing the air inlet pipe to the worktable. When replacement or maintenance is required, only one or a few bolts need to be removed to remove the entire air inlet pipe assembly without damaging the slide rail structure, making maintenance operations more efficient and convenient. After the bolts are tightened, the fixing protrusion and the inner wall of the slide rail are tightly fitted on three or four sides, further preventing micro-movements or offsets caused by vibration, air pressure impact, or external pulling, ensuring that the position of the air supply pipeline is always accurate. The repeatable tightening characteristic of the bolt fixing method ensures that after multiple disassemblies and reassemblies, the fit gap between the slide rail and the connecting protrusion is extremely small, without significant looseness, ensuring the accuracy of assembly, disassembly, and repositioning.

[0013] Furthermore, the upper and lower adjusting blocks are fixed and separated by bolts. Separation of the upper and lower adjusting blocks can be achieved simply by loosening or unloosening the bolts, requiring no special tools or complex procedures. This facilitates both initial assembly and subsequent maintenance, replacement, or repositioning. After multiple disassemblies, simply tightening the bolts to the same torque restores the original clamping state and position, ensuring consistency and repeatability in each assembly.

[0014] Preferably, the air inlet connector on the other side is used to connect to other air supply components or to an external environmental ventilation hose. This air inlet connector can be sequentially connected to the next-level air supply component to achieve multi-stage air path cascading, facilitating the construction of a distributed air source network to meet the centralized air supply needs of large areas or multiple workstations. When cascading air supply is not required, this connector can be directly connected to an external environmental ventilation hose, quickly interfacing with the overall compressed air system in the workshop, simplifying on-site installation and adjustment procedures.

[0015] The beneficial effects of this utility model are as follows: The air inlet pipe is fixedly connected with an air outlet connector, avoiding the loosening problem caused by air pressure fluctuations when directly plugging in a traditional air hose, thus significantly improving the reliability and stability of the air source connection. The air inlet pipe has at least one air outlet connector, allowing for multiple air outlets to be configured according to actual needs, achieving multi-purpose use of a single source, improving air source utilization efficiency, and meeting the needs of simultaneously supplying air to multiple workstations or multiple pneumatic devices. This utility model has a compact structure, with the air inlet and outlet interfaces integrated, facilitating installation and maintenance. It is suitable for various workshop workbench environments, and is particularly adaptable to multi-variety, small-batch assembly operations. Attached Figure Description

[0024] like Figure 1-3 The illustration shows an embodiment of an air supply component for a workbench according to this utility model. It includes an air inlet pipe 1, with air inlet connectors 2 fixedly connected to both sides of the pipe 1. One of the air inlet connectors 2 is used to connect to an air source. The air inlet pipe 1 also has an air outlet connector 4 with at least one outlet. The air inlet pipe 1, with its fixed connection of the air inlet connector 2 and air outlet connector 4, avoids the loosening problem caused by air pressure fluctuations when directly plugged into a traditional air hose, significantly improving the reliability and stability of the air source connection. The air inlet pipe 1 has at least one air outlet connector 4, allowing for multiple outlets to be configured according to actual needs, achieving multi-purpose use of a single source, improving air source utilization efficiency, and meeting the needs of simultaneously supplying air to multiple workstations or multiple pneumatic devices. This utility model has a compact structure, with the air inlet and outlet interfaces integrated, facilitating installation and maintenance. It is suitable for various workshop workbench environments, and is particularly adaptable to multi-variety, small-batch assembly operations.

[0025] Both the air inlet connector 2 and the air outlet connector 4 are fixedly installed on the air inlet pipe 1 via a threaded connection 12. The threaded connection ensures a tight engagement between the contact surfaces of the air inlet connector 2 and the air outlet connector 4 and the air inlet pipe 1. Combined with a sealing ring or gasket, this significantly improves the airtightness at the interface, further reducing the risk of leakage. The overall assembly is comprehensively optimized in terms of air source utilization efficiency, connection reliability, and ease of daily maintenance, making it more suitable for high-intensity, long-cycle workshop operating environments.

[0026] The air outlet connector 4 is located at the bottom of the air inlet pipe 1. Positioning the air outlet connector 4 at the bottom allows for the efficient routing of the air outlet hose or quick-connect fitting along the underside of the workbench, avoiding congestion on the front and sides and improving the overall flexibility of the workbench layout. With the air outlet at the bottom, the condition of the air pipes is readily apparent, making it easier for operators to observe the hose connection status and airflow direction. This helps in the timely detection of any loose connections or potential leaks, ensuring safe production in the workshop.

[0027] The air outlet connector 4 can be a one-way connector, a two-way connector, or a three-way connector. The number of branches can be freely selected according to the actual workstation requirements, enabling flexible allocation of single, dual, or triple air sources to meet the simultaneous air supply needs of different tooling or fixtures. For applications requiring only one air source, a one-way connector can be used to save materials and costs; for applications requiring multiple air sources, two-way or three-way connectors can be selected, eliminating the need for additional distributors or branch pipes, thereby reducing procurement and maintenance costs. The number of air outlet connections can also be further increased to four, five, etc., depending on actual production requirements, offering high flexibility.

[0028] In this embodiment, unlike the previous embodiment, the air inlet pipe 1 is further provided with a connecting component. The air inlet pipe 1 has a protruding connecting flange 11 on its exterior. The connecting component includes an upper adjusting block 31 and a lower adjusting block 32 that is adjustablely connected to the upper adjusting block 31 via bolts. The upper adjusting block 31 and the lower adjusting block 32 cooperate to form a first locking groove 33 and a second locking groove 34. The first locking groove 33 is used to engage with the connecting flange 11, and the second locking groove 34 is used to engage with a protrusion on the workbench. By utilizing the meshing engagement of the locking grooves with the connecting flange 11 and the protrusion on the workbench, a "lock-and-lock" fixing is achieved, allowing for quick positioning without additional bolts or special tools, shortening installation and disassembly time, and improving on-site work efficiency. The double locking groove structure can lock both the pipe body itself and the workbench protrusion, forming dual positioning and locking, significantly enhancing the component's resistance to vibration and loosening, and ensuring stability during long-term operation. The upper and lower adjustment blocks 32 can be disassembled, replaced, or fitted with anti-loosening washers. When wear occurs or readjustment is required, maintenance can be completed by loosening only a few bolts without the need for complete disassembly, making on-site maintenance and repair more convenient.

[0029] The connecting protrusion 11 is fan-shaped, with a smaller inner edge and a larger outer edge. The first and second connecting grooves are also fan-shaped, matching the connecting protrusion 11. This fan-shaped engagement provides a natural conical guiding effect, allowing the upper and lower adjusting blocks 32 to be quickly and accurately positioned during assembly, automatically achieving precise alignment of the angle and center, reducing the number of adjustments and assembly errors. During bolt tightening, the fan-shaped engagement surface has a slight wedging effect, further enhancing the radial clamping force under axial force, ensuring a firm fit between the air inlet pipe 1 and the connector.

[0030] In this embodiment, unlike the previous embodiment, the second snap-fit ​​groove 34 is fixedly connected to a connecting protrusion 35. A fixing protrusion 36 is provided on the other side of the connecting protrusion 35, and the fixing protrusion 36 is used to fixably connect to the slide rail on the workbench. After the fixing protrusion 36 engages with the workbench slide rail, it can achieve precise horizontal movement and positioning under the guide of the slide rail, meeting the needs for rapid adjustment between different workstations and improving layout flexibility. The size of the fixing protrusion 36 can be customized according to the width and shape of the slide rail, compatible with common industrial slide rails such as T-type and U-type. Utilizing the cooperation between the slide rail and the fixing protrusion 36, it is only necessary to loosen the upper and lower adjusting block 32 bolts, slide along the slide rail to the desired position, and then re-lock, significantly shortening the adjustment time and improving on-site efficiency.

[0031] The fixing protrusion 36 is fixedly connected to the connecting protrusion 35 via bolts passing through the slide rail on the worktable, thus fixing the air inlet pipe 1 to the worktable. When replacement or maintenance is required, only one or several bolts need to be removed to remove the entire air inlet pipe 1 assembly without damaging the slide rail structure, making maintenance operations more efficient and convenient. After the bolts are tightened, the fixing protrusion 36 is in close contact with the inner wall of the slide rail on three or four sides, further preventing micro-movements or offsets caused by vibration, air pressure impact, or external pulling, ensuring that the position of the air supply pipeline is always accurate. The repeatable tightening characteristic of the bolt fixing method ensures that after multiple disassemblies and reassemblies, the fit gap between the slide rail and the connecting protrusion 35 is extremely small, without significant looseness, ensuring the accuracy of assembly, disassembly, and repositioning.

[0032] The upper adjusting block 31 and the lower adjusting block 32 are fixed and separated by bolts. Separation of the upper and lower adjusting blocks 32 can be achieved simply by loosening or unloosening the bolts, requiring no special tools or complex procedures. This facilitates initial assembly and subsequent maintenance, replacement, or repositioning. After multiple disassemblies, simply tightening the bolts to the same torque restores the original clamping state and position, ensuring consistency and repeatability in each assembly.

[0033] In this embodiment, unlike the previous embodiment, the air inlet connector 2 on the other side is used to connect with other air supply components or with an external environmental ventilation hose. This air inlet connector 2 can be sequentially connected to the next-level air supply component to achieve multi-stage air path cascading, facilitating the construction of a distributed air source network to meet the centralized air supply needs of a large area or multiple workstations. When cascading air supply is not required, this connector can be directly connected to an external environmental ventilation hose, quickly interfacing with the overall compressed air system in the workshop, simplifying on-site installation and adjustment procedures.

Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
