Description

Technical Field

[0001] This utility model relates to the field of pneumatic transmission technology, specifically a multi-tube quick-connect connector. Background Technology

[0002] The quick-connect fitting is composed of a metal part and a plastic part. The traditional quick-connect fitting uses a snap-fit ​​structure to connect the metal and plastic parts. Multiple sets of air tubes are connected to the quick-connect fitting by inserting them into the plastic part, which allows different tubes to be connected at the same time through a single quick-connect fitting, reducing the workload and cost of installation and maintenance.

[0003] However, the snap-fit ​​structure at the quick-connect connector is prone to problems such as cracking of the plastic part and deformation of the metal part during the snap-fit ​​process. When the quick-connect connector is subjected to high pressure greater than its bearing pressure, the snap-fit ​​structure is prone to detachment, causing the metal part of the quick-connect connector to separate from the plastic part, affecting the stability of the quick-connect connector in the pneumatic transmission process. In view of the shortcomings of the existing technology, we propose a multi-tube docking quick-connect connector to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-tube quick-connect connector, which solves the problems of the quick-connect connector's snap-fit ​​structure, which is prone to cracking of plastic parts and deformation of metal parts during the snap-fit ​​process. When the quick-connect connector is subjected to high pressure exceeding its withstand pressure, the snap-fit ​​structure is prone to detachment, causing the metal parts of the quick-connect connector to separate from the plastic parts, thus affecting the stability of the quick-connect connector during pneumatic transmission.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-tube quick-connect connector, comprising a connecting member integrally formed by injection molding and multiple sets of plug bodies, wherein a guide mechanism is provided on the outside of the multiple sets of plug bodies, and the guide mechanism includes:

[0006] A support ring is sleeved on the outer wall of the plug body, and multiple sets of support plates are fixedly connected to one side of the support ring. One end of each set of support plates is rotatably provided with a set of guide rollers for guiding the tube insertion.

[0007] A support plate for supporting the guide rollers is provided on one side of the support plate for adjusting the position of the support plate.

[0008] A limiting rod is fixedly connected to one side of the support, and one end of the limiting rod is limited to slide inside the support plate.

[0009] Preferably, a limiting bearing is fixedly connected to one side of the support, and the outer wall of one end of the adjusting screw is fixedly connected to the inner wall of the limiting bearing.

[0010] Preferably, a movable component is provided on one side of the support ring, the movable component being used to change the position of the support ring relative to the plug body.

[0011] Preferably, the movable component includes an external threaded ring fixedly disposed on the outer wall of the plug body and an internal threaded ring threadedly sleeved on the outer wall of the external threaded ring and rotatably connected to one side of the support ring.

[0012] Preferably, a connecting bearing is fixedly connected to the side of the support ring away from the support plate, and the outer wall of one end of the internal threaded ring is fixedly connected to the inner wall of the connecting bearing.

[0013] Preferably, a telescopic rod for positioning the movement trajectory of the support ring is fixedly connected between the side of the support ring away from the support plate and the side of the external threaded ring.

[0014] Preferably, a handle is fixedly connected to the side of the internal threaded ring away from the connecting bearing.

[0015] Preferably, a positioning block is fixedly connected to the side of the external threaded ring away from the telescopic rod.

[0016] This utility model discloses a multi-tube quick-connect connector, which has the following beneficial effects: The multi-tube quick-connect connector integrates the connecting part and the multiple plugs through injection molding, making the metal connecting part and the plastic multiple plug bodies a single unit. This effectively avoids the breakage of the multiple plug bodies and can withstand high pressure without easily dislodging. In addition, combined with guide rollers, adjusting screws, support rings, internal thread rings and external thread rings, the position of the guide rollers at the plug socket can be adjusted from multiple directions. This allows the multi-directionally adjusted guide rollers to restrict the insertion path at the socket position, ensuring that the air tubes are inserted into the plug in a straight state.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0027] This application provides a multi-tube quick-connect connector, which solves the problems of the snap-fit ​​structure at the quick-connect connector, where the snap-fit ​​process can easily cause the plastic part to crack and the metal part to deform. When the quick-connect connector is subjected to high pressure greater than its bearing pressure, the snap-fit ​​structure is easy to detach, causing the metal part of the quick-connect connector to separate from the plastic part, affecting the stability of the quick-connect connector in the pneumatic transmission process. The invention achieves the integral molding of the metal part and the plastic part of the quick-connect connector through injection molding.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] This utility model discloses a multi-tube quick-connect connector.

[0030] According to the appendix Figure 1-7As shown, it includes a connector 1 integrally molded by injection molding and multiple plug bodies 2. The diameters of the multiple plug bodies 2 are different, so that the metal connector 1 and the plastic multiple plug bodies 2 are integrated, which effectively avoids the multiple plug bodies 2 from breaking and can withstand high pressure without easily coming loose. It also reduces the number of quick connectors used, and provides different connection methods for connecting pipelines, which facilitates pipeline docking and reduces the workload and cost of installation and maintenance.

[0031] See attached document Figure 2-4 The multiple plug bodies 2 are provided with a guide mechanism 3 on their exterior. The guide mechanism 3 restricts the insertion path of the air tube near the plug body 2 when the air tube is inserted into the plug body 2, ensuring that the air tube is inserted into the plug body 2 in a straight state. The guide mechanism 3 includes a support ring 31. Multiple support rings 31 are respectively sleeved on the outer wall of a plug body 2. Multiple support plates 32 are fixedly connected to one side of the support ring 31. A set of guide rollers 34 for guiding the tube insertion is rotatably provided at one end of each set of support plates 32. The four sets of guide rollers 34 can restrict the insertion path of the plug body 2 at the socket position from four sides.

[0032] See attached document Figure 4 The support 33 is used to support the guide roller 34, that is, the guide roller 34 is rotatably mounted on one end of the support 33. An adjusting screw 35 for changing the position of the support 33 is rotatably mounted on one side of the support plate 32. A limit bearing 351 is fixedly connected to one side of the support 33. The outer wall of one end of the adjusting screw 35 is fixedly connected to the inner wall of the limit bearing 351. Through the limit bearing 351, the adjusting screw 35 and the support 33 are always connected. The limit rod 36 is fixedly connected to one side of the support 33, and one end of the limit rod 36 is limited to slide inside the support plate 32. Through the limit rod 36, the movement path of the support 33 relative to the support plate 32 can be limited.

[0033] Specifically, depending on the diameter of the plug body 2, the adjusting screw 35 on one side of the support plate 32 is rotated, so that the adjusting screw 35 pushes the support 33 at one end to move linearly under the limit of the limiting rod 36, so that the outer wall of the guide roller 34 installed at the support 33 corresponds to the insertion position of the plug body 2. Later, when the air tube is inserted into the interior of a set of plug bodies 2, the outer wall of the air tube contacts the outer walls of the four sets of guide rollers 34 at the same time. At this time, under the restriction of the four sets of guide rollers 34, one end of the air tube is inserted into the interior of the plug body 2 in a straight state.

[0034] See attached document Figure 5-7A movable component 4 is provided on one side of the support ring 31. The movable component 4 is used to change the position of the support ring 31 relative to the plug body 2. For plugs of different sizes, the position of multiple sets of guide rollers 34 relative to the plug body 2 can be adjusted by the movable component 4. The movable component 4 includes an external threaded ring 41 fixedly disposed on the outer wall of the plug body 2 and an internal threaded ring 42 threadedly sleeved on the outer wall of the external threaded ring 41 and rotatably connected to one side of the support ring 31. A connecting bearing 44 is fixedly connected to the side of the support ring 31 away from the support plate 32. One end of the outer wall of the internal threaded ring 42 is fixedly connected to the inner wall of the connecting bearing 44. Through the connected bearing 44, the internal threaded ring 42 and the support ring are connected. The two rings 31 are always connected. A telescopic rod 43 for positioning the movement trajectory of the support ring 31 is fixedly connected between the side of the support ring 31 away from the support plate 32 and the side of the external threaded ring 41. The telescopic rod 43 limits the movement trajectory of the support plate 32, so that the support plate 32 can only move in a straight line. A handle 45 is fixedly connected to the side of the internal threaded ring 42 away from the connecting bearing 44. The handle 45 facilitates the rotation of the internal threaded ring 42. A positioning block 46 is fixedly connected to the side of the external threaded ring 41 away from the telescopic rod 43. The positioning block 46 limits the movement position of the internal threaded ring 42 relative to the external threaded ring 41, preventing them from disengaging.

[0035] Specifically, after the adjustment of the limiting range of the four sets of guide rollers 34 is completed, according to the different sizes of plug body 2, the inner threaded ring 42 connected to the outer wall of the outer threaded ring 41 can be rotated. Under the action of the threaded connection between them, the inner threaded ring 42 and the support ring 31 connected to one end of the inner threaded ring 42 move away from the outer threaded ring 41, thereby driving the four sets of guide rollers 34 set on one side of the support ring 31 to move. This allows the four sets of guide rollers 34 to be set at the plug body 2 socket position as required, thereby restricting the insertion path of the plug body 2 socket position.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
