Description

Technical Field

[0001] This utility model relates to the field of pneumatic connector technology, and in particular to a flow-adjustable pneumatic quick-release right-angle connector. Background Technology

[0002] A pneumatic quick-connect coupling is a type of quick-connect coupling mainly used in air piping and pneumatic tools. It can connect or disconnect pipelines without tools. When the coupling is not connected, that is, when the collar of the female body moves to the other end, the stainless steel ball automatically rolls outward. The male body is disconnected due to the combined valve spring force of the female and male bodies. The valves of the male and female bodies close respectively, instantly blocking the flow of fluid.

[0003] Currently, pneumatic quick-exit connectors include various models and types, such as straight pipe connectors, right-angle connectors, and T-type tee connectors. Among them, the right-angle pneumatic quick-exit connector, after installation, can only fully open and close the pipeline during adjustment, and cannot adjust the flow rate. This makes it impossible to achieve partial gas passage in special circumstances, resulting in inconvenience. To address this, we propose a flow-adjustable pneumatic quick-exit right-angle connector. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a flow-adjustable pneumatic quick-exhaust right-angle connector. Through the cooperation of the adjustment component and the operation component, the gas flow rate passing through the right-angle connector can be actively controlled, and it is easy to operate.

[0005] To solve the above-mentioned technical problems, this utility model solves the problem that the original right-angle pneumatic quick-connect coupling, after installation, can only fully open and close the pipeline during adjustment, and cannot adjust the flow rate. This results in the inconvenience of using the coupling when partial gas passage is required in special circumstances.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable-flow pneumatic quick-exhaust right-angle connector includes a connector body with a first cavity and a second cavity communicating with each other; an adjustment component disposed in the first cavity and the second cavity, comprising two sets of conical sleeves respectively disposed in the first cavity and the second cavity, with multiple sets of fixing blocks fixedly connected to the outside of the two sets of conical sleeves and fixedly connected to the first cavity and the second cavity, and each set of conical sleeves having a conical block adapted to its interior; the adjustment component is used to block the gas between the first cavity and the second cavity; and an operating component disposed on the connector body and connected to the adjustment component, used to control the operation of the adjustment component, thereby driving the two sets of conical blocks to cooperate with the corresponding conical sleeves, thereby adjusting the gas flow rate inside the connector body. This solves the problem that the original right-angle pneumatic quick-exhaust connector, after installation, could only fully open and fully close the pipeline during adjustment, and could not adjust the flow rate, making it inconvenient to use when partial gas passage is required in special circumstances.

[0008] Preferably, the adjustment assembly further includes a fixing plate disposed in the first cavity and fixedly connected to the corresponding conical block. The fixing plate has a sliding groove, and a first threaded rod is fixedly connected to one end of the fixing plate away from the conical block. The end of the first threaded rod away from the fixing plate is located outside the connector body. The fixing plate is connected to an adapter mechanism connected to another conical block through the sliding groove.

[0009] Preferably, the adapter mechanism includes a fixed shaft disposed in the second cavity and fixedly connected to the corresponding conical block. A limiting groove is formed on the fixed shaft, and a limiting block adapted to the sliding groove is slidably connected through the limiting groove. A second threaded rod is fixedly connected to one end of the fixed shaft away from the conical block, and one end of the second threaded rod is located outside the connector body.

[0010] Preferably, the operating component includes two sets of fixing seats respectively sleeved on the first threaded rod and the second threaded rod. Both sets of fixing seats are fixedly connected to the outer wall of the connector body. Threaded seats are rotatably connected to the fixing seats, and the two sets of threaded seats are threadedly connected to the first threaded rod and the second threaded rod respectively.

[0011] Preferably, both the first threaded rod and the second threaded rod have a blocking block fixedly connected to one end outside the joint body, which helps to ensure the connection between the first threaded rod, the second threaded rod and the corresponding threaded seat, and makes the overall operation more stable.

[0012] Preferably, a sealing gasket is provided at the connection between the bottom end of the fixed base and the joint body to ensure a seal. This helps to ensure that the connection between the first threaded rod and the second threaded rod remains sealed when they move, preventing any impact on the overall function of the joint.

[0013] Preferably, both sets of threaded seats are fixedly connected to multiple sets of rotatable protrusions on their outer sides, which facilitates manual and active rotation of the threaded seats, thereby driving the adjustment component through the operating component, and finally adjusting the internal structure of the connector body through gas.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention solves the problem that, after installation, the original right-angle pneumatic quick-connect fitting could only fully open or close the pipe during adjustment, without being able to adjust the flow rate. This resulted in inconvenience when partial gas passage was required in special circumstances. If it is necessary to control the gas flow inside the fitting body, the operating component is controlled, which in turn drives the adjusting component to operate within the fitting body, thereby controlling the amount of gas passing through.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. Example

[0023] Please see Figures 1-4 An adjustable pneumatic quick-exhaust right-angle connector includes a connector body 1, with a first cavity 2 and a second cavity 3 communicating with each other inside the connector body 1; an adjustment component 4, disposed in the first cavity 2 and the second cavity 3, comprising two sets of conical sleeves 5 respectively disposed in the first cavity 2 and the second cavity 3, with multiple sets of fixing blocks 6 fixedly connected to the outside of the two sets of conical sleeves 5 and fixedly connected to the first cavity 2 and the second cavity 3, and each set of conical sleeves 5 is provided with a conical block 7 adapted to its interior, the adjustment component 4 is used to block the gas between the first cavity 2 and the second cavity 3; and an operating component 8, disposed on the connector body 1 and connected to the adjustment component 4, the operating component 8 is used to control the operation of the adjustment component 4, thereby driving the two sets of conical blocks 7 to cooperate with the corresponding conical sleeves 5, thereby adjusting the gas flow rate inside the connector body 1.

[0024] Please see Figures 1-4 The adjustment assembly 4 also includes a fixing plate 9 disposed in the first cavity 2 and fixedly connected to the corresponding conical block 7. The fixing plate 9 has a sliding groove 10, and a first threaded rod 11 is fixedly connected to the end of the fixing plate 9 away from the conical block 7. The end of the first threaded rod 11 away from the fixing plate 9 is located outside the connector body 1. The fixing plate 9 is connected to an adapter mechanism 12 connected to another conical block 7 through the sliding groove 10. The adapter mechanism 12 includes a fixing shaft 13 disposed in the second cavity 3 and fixedly connected to the corresponding conical block 7. A limit groove 14 is provided on the fixing shaft 13, and a limit block 15 adapted to the sliding groove 10 is slidably connected through the limit groove 14. A second threaded rod 16 is fixedly connected to the end of the fixing shaft 13 away from the conical block 7. One end of the second threaded rod 16 is located outside the connector body 1. In order to ensure the stability of the connection between the first threaded rod 11 and the second threaded rod 16 and the corresponding threaded seat 18, a blocking block is fixedly connected to the end of the first threaded rod 11 and the second threaded rod 16 located outside the connector body 1.

[0025] Please see Figures 1-3The operating component 8 includes two sets of fixed seats 17 respectively fitted onto the first threaded rod 11 and the second threaded rod 16. Both sets of fixed seats 17 are fixedly connected to the outer wall of the connector body 1. Threaded seats 18 are rotatably connected to the fixed seats 17. The two sets of threaded seats 18 are threadedly connected to the first threaded rod 11 and the second threaded rod 16 respectively. In order to ensure that the connection between the first threaded rod 11 and the second threaded rod 16 remains sealed when they move, a sealing gasket is provided at the connection between the bottom end of the fixed seat 17 and the connector body 1 to ensure a seal. In addition, in order to facilitate manual rotation of the threaded seats 18, multiple sets of rotatable protrusions are fixedly connected to the outer side of both sets of threaded seats 18.

[0026] During implementation, after the connector body 1 is installed, when it is necessary to adjust the amount of gas passing through, the two sets of threaded seats 18 are rotated one after another. When the threaded seats 18 rotate on the fixed seat 17, they are connected to the first threaded rod 11 through the threaded connection of the threaded seats 18. The first threaded rod 11 moves into the connector body 1 at this time, and drives the fixed plate 9 to move simultaneously. At the same time, the fixed plate 9 slides through the sliding groove 10 and the limiting block 15, and then drives the fixed conical block 7 to move into the conical sleeve 5 during the movement. The outer side of the conical block 7 gradually approaches the inner wall of the conical sleeve 5, and the outer wall of the conical sleeve 5 is fixed in the first cavity 2 by multiple sets of fixed blocks 6, so that the position of the conical sleeve 5 is fixed and can bear the pushing force of the conical block 7 on the conical sleeve 5. At this time, the closer the conical block 7 is to the inner wall of the conical sleeve 5, the less gas passes through the connector body 1, until the conical block 7 is completely attached to the inner wall of the conical sleeve 5, thus achieving the effect of completely blocking the gas.

[0027] Through the threaded connection between the threaded seat 18 and the second threaded rod 16, the second threaded rod 16 moves into the second cavity 3 when being adjusted, and drives the fixed shaft 13 to move. At this time, the fixed shaft 13 slides through the limiting groove 14 and the limiting block 15. At the same time, through the cooperation of the limiting block 15 and the sliding groove 10, the first threaded rod 11 and the second threaded rod 16 cannot rotate with the threaded seat 18, thus making the adjustment smooth. When complete closure is required, the existing closure method of the connector body 1 can be used to completely block the gas. When a certain amount of gas needs to pass through, the two sets of threaded seats 18 can be rotated one after the other, thus making the flow rate adjustable and improving the overall practicality.
